                                  THE COMPANY
 
    The Company is a technology and service driven provider of discount
securities brokerage and related financial services. The Company provides retail
brokerage services to individual investors throughout the United States and
internationally through a variety of electronic mediums, including the Internet,
and through registered representatives. The Company offers trade execution for
stocks, mutual funds, options and bonds, as well as market data and research.
The Company also provides clearing and execution services to its own retail
brokerage operations, as well as to independent broker-dealers, depository
institutions, registered investment advisors and financial planners. The Company
had approximately 111,000 active accounts as of September 27, 1996, an increase
from approximately 86,000 active accounts as of September 29, 1995. Average
daily trading volume during the month of October 1996 was approximately 4,200
executed transactions. This compares to an average daily trading volume of
approximately 3,700 executed transactions during fiscal 1996.
 
    The Company has experienced significant growth over the past five years
while expanding profitability. Transaction volumes have increased at an average
annual rate of 45% from fiscal 1992 through fiscal 1996. Net revenues and net
income have grown at average annual rates of 43% and 61%, respectively, over the
same period. These increases, along with the Company's ability to leverage the
use of technology and its aggressive marketing, have resulted in an average
return on equity over the same five-year period of 51% and an operating margin
that has increased from 21% in fiscal 1992 to 34% in fiscal 1996.
 
    The Company's leadership position in the discount brokerage industry is a
result of its unique approach to the delivery of retail brokerage and execution
and clearing services. Retail brokerage services are provided under four
distinct brand names, each of which offers a range of services and commission
rates designed to appeal to specific groups of investors within the discount
brokerage market. Accutrade, Inc. ("Accutrade") offers advanced technology
delivery systems to sophisticated investors. K. Aufhauser & Company, Inc.
("Aufhauser") provides third-party research and investment analysis to
experienced investors. Ceres Securities, Inc. ("Ceres") offers execution
services to customers who want minimal transaction costs. eBroker, a division of
the Company's subsidiary All American Brokers, Inc. ("All American"), provides
execution services exclusively through the Internet. This branding strategy
allows the Company to segment the marketplace, which enables it to align the
cost structures of its discount brokerage businesses with the level of services
desired by their customers. By providing clearing and execution services, the
Company is able to expand its customer base, provide synergies to the Company's
retail brokerage businesses and diversify its revenues.
 
    The Company offers its retail brokerage customers the opportunity to conduct
business through a diversity of electronic mediums, including the Internet,
automated touchtone telephone, personal computer, the Sharp Zaurus personal
digital assistant and facsimile machine. During the quarter ended September 27,
1996, approximately 43% of the Company's transactions were generated through
electronic mediums. The Company also maintains a staff of over 130 registered
representatives to service customers directly. By combining innovative
technology and a range of delivery systems with over 21 years of industry
expertise, the Company is able to provide sophisticated services and efficient
transaction execution while
 
                                       3
<PAGE>
offering commissions that are among the lowest in the industry. The Company
believes that its brokerage commissions are in most cases substantially lower
than those charged by full-commission or traditional discount brokerage firms
for similar transactions.
 
    The Company also provides services to over 70 independent broker-dealers,
depository institutions, registered investment advisers and financial planners
through AmeriTrade Clearing, Inc. ("AmeriTrade Clearing") and AmeriVest, a
division of All American. AmeriTrade Clearing provides complete securities
transaction clearing and execution services to each of the Company's discount
brokerage businesses, as well as to independent broker-dealers. AmeriVest
provides discount brokerage services to depository institutions that do not
operate their own registered broker-dealers. Providing services to these
correspondents allows the Company to reach investors who rely on more
traditional investment services, such as investment advice, or who prefer to
deal with local or regional financial service providers. During the year ended
September 27, 1996, the delivery of financial services to unaffiliated
correspondents accounted for approximately 11% of the Company's net revenues.
 
BUSINESS STRATEGY
 
    The Company believes that four significant trends currently drive growth in
the discount brokerage industry. First, the unbundling of brokerage services
from other financial and information services has permitted investors to pick
and choose among various financial and information service providers for
specified services. Second, consumers have expanded access to powerful
technology, which they are using with increasing frequency. Third, investors are
becoming more self-reliant and value-conscious with respect to their financial
matters. Finally, the growth in financial assets held by these individuals is
accelerating, due to the largest transference of wealth in history. See
"Business--Industry." The Company believes that its focus on innovative
technology and cost effective services permits it to take advantage of these
trends. The Company seeks to capitalize on the changing financial services
industry and to increase its market share by pursuing the following strategies:
 
    - MARKET DISTINCT BRANDS TO SPECIFIC GROUPS OF DISCOUNT BROKERAGE
      CUSTOMERS.  The Company markets a range of services and commission rates
      designed to appeal to specific groups of investors within the discount
      brokerage market. By providing specified services to targeted customers in
      the discount brokerage market, the Company believes that it appeals to a
      broader range of investors seeking brokerage services at discount prices.
      Accutrade provides more technologically advanced solutions than the
      Company's other brands, including program trading and basket trading
      available through Accutrade FOR WINDOWS. Aufhauser is marketed to
      experienced investors seeking research and customer service. Aufhauser
      also provides international investors interested in the U.S. securities
      market with multi-lingual service and with toll-free telephone access from
      36 countries. Ceres is directed at investors who are seeking simple and
      efficient execution services at the lowest possible transaction cost.
      eBroker serves investors who are comfortable with the Internet and prefer
      to trade exclusively through electronic communication in exchange for
      low-priced trade executions. Through this market segmentation approach,
      the Company is able to deliver products and services tailored to the
      specific needs of its customers in the most cost efficient manner. See
      "Business-- Discount Securities Brokerage Services."
 
    - CREATE TECHNOLOGICALLY INNOVATIVE SOLUTIONS TO INVESTOR NEEDS.  The
      Company is a technology leader in the retail brokerage and clearing and
      execution businesses:
 
       - In 1988, the Company was the first broker to implement automated
         touchtone trading technology, which allows customers to place trades
         and obtain quotes electronically using the telephone.
 
       - In 1994, the Company became the first brokerage firm to offer trading
         services over the Internet.
 
                                       4

       - In 1995, the Company introduced a trading application for the Sharp
         Zaurus personal digital assistant, which allows portable access to
         trades, quotes, positions and balances.
 
       - In 1996, the Company introduced Accutrade FOR WINDOWS, the first online
         investing system that permits individual investors to engage in program
         trading and basket trading.
 
       - The Company recently completed the development and introduction of
         AmeriTrade OnLine, a technologically advanced financial system for its
         correspondents that integrates the products and services of some of the
         world's foremost financial service vendors into one Internet-based
         system.
 
       The Company is actively pursuing additional technologies to service the
       rapidly evolving financial services industry. See "Business--Strategic
       Relationships" and "Business--Product Development."
 
    - PROVIDE THE BEST TRANSACTION VALUES TO INVESTORS.  The Company strives to
      offer investors the best transaction values in the financial services
      industry by providing specified services at prices that are among the
      lowest in the industry. eBroker offers a flat $12.00 commission on
      Internet-only trades for an equity order of any size. For investors who
      want access to registered representatives as well as the Internet to place
      trades, Ceres charges a flat $18.00 fee for an equity order of any size.
      Investors desiring more services, such as increased technology, more
      trading options or research, may use Aufhauser or Accutrade. Through more
      efficient operations, an increasing number of transactions and the use of
      advanced technology, the Company strives to minimize costs, which allows
      it to offer some of the best transaction values in the industry.
 
    - EXPAND CLEARING AND EXECUTION SERVICES TO CORRESPONDENTS.  The Company
      intends to continue to leverage the advanced technology offered to its
      retail brokerage customers to increase its clearing and execution business
      with correspondents. Providing clearing and execution services permits the
      Company to expand its customer base by allowing the Company to reach
      investors outside of its targeted retail brokerage markets. Providing
      clearing and execution services for its own broker-dealer subsidiaries
      allows the Company to realize efficiencies and achieve strategic
      flexibility as a result of its ability to control the delivery of these
      services without relying on third parties. In addition, the Company's
      clearing and execution services diversify the Company's revenues. See
      "Business--Clearing and Execution Services."
 
                                 --------------

                                  RISK FACTORS
 
    IN DETERMINING WHETHER TO PURCHASE THE SHARES OF CLASS A STOCK BEING OFFERED
HEREBY, PROSPECTIVE INVESTORS SHOULD CAREFULLY CONSIDER THE FOLLOWING FACTORS IN
ADDITION TO THE OTHER INFORMATION CONTAINED IN THIS PROSPECTUS.
 
SECURITIES BUSINESS
 
    Substantially all of the Company's revenues are derived from discount
securities brokerage and clearing and execution services. The securities
business is subject to fluctuations and is directly affected by national and
international economic conditions, broad trends in business and finance and
fluctuations in volume and price levels of securities transactions, all of which
are beyond the control of the Company. Reduced trading volume generally results
in reduced transaction revenues and decreased profitability. Severe market
fluctuations in the future could have a material adverse effect on the Company's
business, financial condition and operating results. The securities business is
also subject to various other risks, including customer default and employees'
misconduct, errors and omissions. Losses associated with these risks could have
a material adverse effect on the Company's business, financial condition and
operating results. The securities industry has undergone many fundamental
changes during the last two decades, including regulation and deregulation at
federal and state levels and consolidation. See "Business-- Industry." There can
be no assurance that future changes will not have a material adverse effect on
the Company's business, financial condition and operating results. In addition,
commissions charged to customers of discount brokerage services have steadily
decreased, and the Company expects such decreases to continue. There can be no
assurance that such decreases will not have a material adverse effect on the
Company's business, financial condition and operating results. See
"--Competition."
 
LOSS OF FUTURE ORDER FLOW PAYMENTS
 
    The Company has arrangements with several execution agents to receive cash
payments in exchange for routing trade orders to these firms for execution.
Although this practice of receiving payments for order flow is widespread in the
securities industry, it has come under increased scrutiny in recent years.
Furthermore, competition between execution agents has narrowed the spread
between bid and ask prices, which has made it less profitable for execution
agents to offer order flow payments to broker-dealers. The revenues received by
the Company under these arrangements for the year ended September 27, 1996
amounted to approximately 15% of net revenues. The Company expects such payments
to decrease as competition increases; however, the Company has taken steps and
intends to take further steps to mitigate the financial impact of the loss of
these revenues on the Company. See "Business--Investments." Nevertheless, there
can be no assurance that the loss of any significant portion of these revenues
will not have a material adverse effect on the Company's business, financial
condition and operating results. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
EVOLVING MARKETS AND TECHNOLOGIES
 
    During the quarter ended September 27, 1996, approximately 43% of the
Company's transactions were generated through electronic mediums, including the
Internet. The market for electronic discount brokerage services is at an early
stage of development and is rapidly evolving. As is typical for new and rapidly
evolving industries, demand and market acceptance for recently introduced
services and products are subject to a high level of uncertainty. The Company's
services over the Internet, automated touchtone telephone and personal computer
involve alternative approaches to securities transactions and, as a result,
intensive marketing and sales efforts may be necessary to educate prospective
customers regarding the uses and benefits of the Company's electronic discount
brokerage services and products. Consumers who already obtain brokerage services
from more traditional full-commission brokerage firms, or even discount brokers,
may be reluctant or slow to change to obtaining brokerage services over the
Internet, automated touchtone telephone and personal computer. Moreover, the
security and privacy concerns of existing and potential users of the Company's
services may inhibit the growth of electronic discount brokerage trading.

In addition, the Company's future success will depend, in part, on its ability
to develop and use leading technologies, respond to technological advances,
enhance its existing services and products and develop new services and products
on a timely and cost-effective basis. There can be no assurance that the market
for electronic discount brokerage services will continue to grow, or that the
Company will be successful in effectively developing or using new technologies,
responding to technological advances or developing, introducing or marketing
service and product enhancements or new services and products. See
"Business--Product Development."
 
    During the quarter ended September 27, 1996, approximately 17% of the
Company's transactions were generated over the Internet. Sales of some of the
Company's services and products will depend upon the broader adoption of the
Internet by consumers as a medium for commerce and communication. Use of the
Internet depends on the development of the necessary infrastructure and
complementary services and products, such as high speed modems and high speed
communication lines. As the number of users and amount of traffic on the
Internet continues to increase, there can be no assurance that the Internet
infrastructure will continue to be able to support the demands placed on it. In
addition, delays in the development or adoption of new standards and protocols
to handle increased levels of Internet activity or increased governmental
restrictions could impede further use of the Internet. Moreover, consumer
concerns about the Internet (including security, reliability, cost, ease of use,
accessibility and quality of service) remain unresolved and may negatively
affect the growth of Internet use. As a result, there can be no assurance that
the number of the Company's transactions generated over the Internet will
continue to increase.
 
COMPETITION
 
    The market for discount brokerage services, particularly electronic
brokerage services, is new, rapidly evolving and intensely competitive. The
Company expects competition to continue and intensify in the future. The Company
encounters direct competition from approximately 100 other discount brokerage
firms, many of which provide electronic brokerage services. These competitors
include such discount brokerage firms as Charles Schwab & Co., Inc., Fidelity
Brokerage Services, Inc., Waterhouse Securities, Inc., Quick & Reilly, Inc. and
E*Trade Group, Inc. The Company also encounters competition from established
full-commission brokerage firms as well as financial institutions, mutual fund
sponsors and other organizations, some of which provide electronic brokerage
services. The clearing business is also highly competitive. The Company's
clearing broker subsidiary, AmeriTrade Clearing, competes with over 40 firms
that provide clearing and execution services to the securities industry.
 
    A number of the Company's competitors have significantly greater financial,
technical, marketing and other resources than the Company. Some of the Company's
competitors also offer a wider range of services and financial products than the
Company and have greater name recognition and more extensive customer bases than
the Company. These competitors may be able to respond more quickly to new or
changing opportunities, technologies and customer requirements than the Company
and may be able to undertake more extensive promotional activities, offer more
attractive terms to customers and adopt more aggressive pricing policies than
the Company. Moreover, current and potential competitors have established or may
establish cooperative relationships among themselves or with third parties to
enhance their services and products. The Company expects that new competitors or
alliances among competitors will emerge and may acquire significant market
share.
 
    The general financial success of companies within the securities industry
over the past several years has strengthened existing competitors. The Company
believes that such success will continue to attract new competitors to the
industry, such as depository institutions, software development companies,
insurance companies, providers of online financial and information services and
others. Commercial depository institutions and other financial institutions have
become a competitive factor in the securities industry by offering their
customers certain financial services traditionally provided by brokerage firms.
While it is not possible to predict the type and extent of competitive services
that commercial depository institutions and
 
                                       9
<PAGE>
other financial institutions ultimately may offer or whether regulatory or
legislative barriers will be repealed or modified, brokerage firms such as the
Company may be adversely affected by such competition.
 
    There can be no assurance that the Company will be able to compete
effectively with current or future competitors or that the competitive pressures
faced by the Company will not have a material adverse effect on the Company's
business, financial condition and operating results. See
"Business--Competition."
 
DEPENDENCE ON COMPUTER SYSTEMS
 
    The Company receives and processes trade orders through a variety of
electronic mediums, including the Internet, automated touchtone telephone,
personal computer and the Sharp Zaurus personal digital assistant. These methods
of trading are heavily dependent on the integrity of the electronic systems
supporting them. Extraordinary trading volumes could cause the Company's
computer systems to operate at an unacceptably low speed or even fail. The
Company has never experienced a systems failure that has resulted in a material
loss to the Company. However, any significant degradation or failure of the
Company's computer systems or any other systems in the trading process (e.g.,
online service providers, record keeping and data processing functions performed
by third parties and third-party software such as Internet browsers) could cause
customers to suffer delays in trading. Such delays could cause substantial
losses for customers and could subject the Company to claims from customers for
losses, including litigation claiming fraud or negligence. There can be no
assurance that the Company's network structure will operate appropriately in the
event of a computer systems failure or that, in the event of a tornado, fire or
any other natural disaster, power or telecommunications failure, act of God or
war, the Company will be able to prevent an extended computer systems failure.
Any computer systems failure that causes interruptions in the Company's
operations could have a material adverse effect on the Company's business,
financial condition and operating results. See "Business--Systems".
 
DEPENDENCE ON KEY PERSONNEL
 
    The Company's business is dependent upon a small number of key executive
officers, principally J. Joe Ricketts, the Company's Chairman and Chief
Executive Officer. The Company has employment agreements with J. Joe Ricketts,
Joseph A. Konen, President and Chief Operating Officer, and Robert T. Slezak,
Vice President, Chief Financial Officer and Treasurer. The Company does not
maintain any "key person" life insurance policy on any of its executives for the
benefit of the Company. The loss of the services of any of the key personnel or
the inability to identify, hire, train and retain other qualified personnel in
the future could have a material adverse effect on the Company's business,
financial condition and operating results. See "Business--Employees" and
"Management--Executive Officer Compensation--Employment Agreements."
 
OWNERSHIP AND CONTROL BY AFFILIATES
 
    Upon completion of the Offering, J. Joe Ricketts, Marlene M. Ricketts, and
trusts held for the benefit of their children, grandchildren and their spouses
(collectively, the "Ricketts Family") will own approximately   % of the Class A
Stock and all of the Class B Stock, which will constitute approximately   % of
the Common Stock (  % if the Underwriters' over-allotment option is exercised in
full). See "Principal and Selling Stockholders." As a result, the Ricketts
Family will have the ability to control all fundamental matters affecting the
Company, including the election of the majority of the directors of the Company,
the acquisition or disposition of the Company's assets, the future issuance of
Common Stock or other securities of the Company and the declaration of any
dividend payable on the Common Stock. In addition, the Ricketts Family could
convert a portion of its Class B Stock into Class A Stock and subsequently
dispose of such shares, thereby substantially reducing its economic interest in
the Company while retaining the ability to elect the majority of the directors
of the Company. However, all the Class B Stock shall automatically convert into
Class A Stock if the number of shares of outstanding Common Stock held by the
 
                                       10
<PAGE>
Control Group, which includes the Ricketts Family and its lineal descendants,
falls below 20% of the total number of shares of outstanding Common Stock. See
"Description of Capital Stock--Conversion Rights."
 
STRATEGIC ACQUISITIONS AND RELATIONSHIPS
 
    The Company has pursued and may in the future pursue strategic acquisitions
of complementary businesses and technologies. Acquisitions entail numerous
risks, including difficulties in the assimilation of acquired operations and
products, diversion of management's attention to other business concerns,
amortization of acquired intangible assets and potential loss of key employees
of acquired companies. There can be no assurance that the Company will be able
to integrate successfully any operations, personnel, services or products that
might be acquired in the future or that any acquisition will enhance the
Company's business, financial condition or operating results. The Company has
established a number of strategic relationships with online service providers
and information service providers. There can be no assurance that any such
relationships will be maintained, that if such relationships are maintained,
they will be successful or profitable or that the Company will be successful in
developing any new strategic alliances. See "Business--Strategic Relationships."
 
CLEARING OPERATIONS
 
    AmeriTrade Clearing provides clearing and execution services to each of the
Company's discount brokerage businesses, as well as to independent
broker-dealers, depository institutions, registered investment advisors and
financial planners. Clearing services include the confirmation, receipt,
settlement and delivery functions involved in securities transactions. As a
clearing broker, AmeriTrade Clearing also assumes direct responsibility for the
possession and control of customer securities and other assets and the clearance
of customer securities transactions. Clearing brokers are subject to substantial
regulatory control and examination. Errors in performing clearing functions or
reporting could lead to civil penalties imposed by the Securities and Exchange
Commission (the "SEC"), the National Association of Securities Dealers, Inc.
(the "NASD"), other self-regulatory organizations ("SROs") and other regulatory
bodies. Errors in the clearing process also may lead to civil liability for
actions in negligence brought by parties who are financially harmed as a result
of clerical errors related to the handling of customer funds and securities.
There can be no assurance that any of such errors will not have a material
adverse effect on the Company's business, financial condition and operating
results.
 
    In connection with its clearing and execution services, the Company makes
margin loans to customers collateralized by customer securities and periodically
borrows securities to cover trades. By permitting customers to purchase
securities on margin, the Company is subject to risks inherent in extending
credit, especially during periods of rapidly declining markets in which the
value of the collateral held by the Company could fall below the amount of a
customer's indebtedness. In addition, under specific regulatory guidelines, the
Company collateralizes borrowings of securities by depositing cash or securities
with lending institutions. Failure to maintain cash deposit levels at all times
at least equal to the value of the related securities can subject the Company to
risk of loss should there be sharp changes in market values of substantial
amounts of securities and parties to the borrowing transactions fail to honor
their commitments. See "Business--Operations."
 
ENCRYPTION TECHNOLOGY
 
    The Company relies on encryption and authentication technology, including
public key cryptography technology licensed from Netscape Communications, Inc.
to provide the security and authentication necessary to effect secure
transmission of confidential information over the Internet. There can be no
assurance that advances in computer capabilities, new discoveries in the field
of cryptography or other events or developments will not result in a compromise
or breach of the Netscape technology or other algorithms used by the Company to
protect customer transaction data. Any such compromise of the
 
                                       11
<PAGE>
Company's security could have a material adverse effect on the Company's
business, financial condition and operating results.
 
RELATED PARTY TRANSACTIONS AND POTENTIAL CONFLICTS
 
    The Company has entered into a certain lease transaction with the Ricketts
Family and will continue to enter into similar transactions in the future. The
Company's intention is that all such transactions will be on terms at least as
favorable to the Company as would be obtainable in arm's-length dealings with
unrelated third persons. However, the ongoing relationship between the Company
and the Ricketts Family may result in conflicts of interest between the Company
and the Ricketts Family, which may result in action taken by the Company that
does not fully reflect the interests of all stockholders of the Company. In
order to minimize any conflict of interest, the fairness and reasonableness of
any compensation paid to the Ricketts Family or their affiliates by the Company
and any material transaction between the Ricketts Family or its affiliates and
the Company in the future will be subject to approval by a majority of the
independent members of the Board of Directors of the Company (the "Board") or by
an independent firm selected by such members. See "Certain Transactions."
 
GOVERNMENT REGULATION
 
    The securities industry in the United States is subject to extensive
regulation under both federal and state laws. In addition, the SEC, the NASD,
other SROs, such as the various stock exchanges, and other regulatory bodies,
such as state securities commissions, require strict compliance with their rules
and regulations. As a matter of public policy, regulatory bodies are charged
with safeguarding the integrity of the securities and other financial markets
and with protecting the interests of customers participating in those markets,
and not with protecting the interests of the Company's stockholders.
Broker-dealers are subject to regulations covering all aspects of the securities
business, including sales methods, trade practices among broker-dealers, use and
safekeeping of customers' funds and securities, capital structure, record
keeping and the conduct of directors, officers and employees. AmeriTrade
Clearing also is required to comply with many complex laws and rules as a
clearing broker, including rules relating to possession and control of customer
funds and securities, margin lending and execution and settlement of
transactions. Failure to comply with any of these laws, rules or regulations
could result in censure, fine, the issuance of cease-and-desist orders or the
suspension or expulsion of a broker-dealer or any of its officers or employees,
any of which could have a material adverse effect on the Company's business,
financial condition and operating results.
 
    The Company has recently initiated an aggressive marketing campaign designed
to bring greater brand name recognition to its product lines. All marketing
activities by the Company's subsidiaries are regulated by the NASD. The NASD can
impose certain penalties, including censure, fine, suspension of all
advertising, the issuance of cease-and-desist orders or the suspension or
expulsion of a broker-dealer and certain of its officers or employees for
violations of the NASD's advertising regulations.
 
    It is the Company's intent to expand its business in United States
securities to other countries. In order to expand its services internationally,
the Company must comply with regulatory controls of each specific country in
which it conducts business. The brokerage industry in many foreign countries is
heavily regulated. The varying compliance requirements of these different
regulatory jurisdictions may limit the Company's ability to expand
internationally. See "Business--Government Regulation."
 
NET CAPITAL REQUIREMENTS
 
    The SEC, the NASD and various other regulatory agencies have stringent rules
with respect to the maintenance of specific levels of net capital by securities
brokers, including the SEC's Uniform Net Capital Rule (the "Net Capital Rule"),
which governs each of the Company's subsidiaries. Failure to maintain the
required net capital may subject a firm to suspension or revocation of
registration by the SEC and
 
                                       12
<PAGE>
suspension or expulsion by the NASD and other regulatory bodies and ultimately
could require the firm's liquidation. In addition, a change in the net capital
rules, the imposition of new rules or any unusually large charge against net
capital could limit those operations of the Company that require the intensive
use of capital, such as the financing of customer account balances, and also
could restrict the Company's ability to withdraw capital from its brokerage
subsidiaries, which in turn could limit the Company's ability to pay dividends,
repay debt and repurchase shares of its outstanding stock. A significant
operating loss or any unusually large charge against net capital could adversely
affect the ability of the Company to expand or even maintain its present levels
of business, which could have a material adverse effect on the Company's
business, financial condition and operating results. See "Business--Government
Regulation."
 
FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FINANCING
 
    The Company currently anticipates that its available cash resources and
credit facilities, combined with the net proceeds to the Company from the
Offering, will be sufficient to meet its presently anticipated working capital
and capital expenditure requirements for the foreseeable future based on known
and reasonably estimated trends. However, if the Company needs to raise
additional funds in order to support more rapid expansion, develop new or
enhanced services and products, respond to competitive pressures, acquire
complementary businesses or technologies or respond to unanticipated
requirements, there can be no assurance that additional financing will be
available when needed on terms favorable to the Company. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon completion of the Offering, the Company will have approximately
shares of Common Stock outstanding, including       shares of Class A Stock
offered hereby and 7,697,650 "restricted" shares of Common Stock. The shares of
Class A Stock offered hereby will be freely tradeable without restriction or
further registration under the Securities Act of 1933, as amended (the
"Securities Act"), by persons other than "affiliates" of the Company within the
meaning of Rule 144 promulgated under the Securities Act. The holders of
restricted shares generally will be entitled to sell these shares in the public
securities market without registration under the Securities Act to the extent
permitted by Rule 144 (or Rule 145, as applicable) promulgated under the
Securities Act or any exemption under the Securities Act. Of the 7,697,650
restricted shares, 7,568,743 shares of Common Stock are currently eligible for
sale under Rule 144, and 128,907 shares of Common Stock will be eligible for
sale under Rule 144 beginning in November 1998. Certain employees of the Company
purchased 59,462 shares of Class A Stock from J. Joe Ricketts in November 1996.
Although those shares will be eligible for sale under Rule 144 beginning in
November 1998, the respective stock purchase agreements between such employees
and Mr. Ricketts prohibit the sale of such shares until May 1999, subject to
certain limited exceptions. In addition, the Company intends to register under
the Securities Act 500,000 shares of Class A Stock reserved for issuance under
its employee stock option plan. See "Management--Executive Officer
Compensation--1996 Long Term Incentive Plan."
 
    Each of the Company, its directors and officers, the Selling Stockholders
and certain other stockholders has agreed that it will not offer, sell, contract
to sell, announce its intention to sell, pledge or otherwise dispose of,
directly or indirectly, or file with the SEC a registration statement under the
Securities Act relating to, any additional shares of the Class A Stock or
securities convertible into or exchangeable or exercisable for any shares of the
Class A Stock without the prior written consent of CS First Boston Corporation
for a period of 180 days after the date of this Prospectus, except, in the case
of the Company, issuances pursuant to the exercise of employee stock options
granted under the Company's existing employee benefit plans and, in the case of
the directors and officers, Selling Stockholders and certain other stockholders,
gifts and pledges of shares where the donees or pledgees, as the case may be,
agree in writing to be bound by the terms of such agreement. See "Shares
Eligible for Future Sale" and "Underwriting."
 
                                       13
<PAGE>
    Future sales of a substantial amount of Class A Stock in the public market,
or the perception that such sales may occur, could adversely affect the market
price of the Class A Stock prevailing from time to time in the public market.
See "Shares Eligible for Future Sale."
 
LACK OF PRIOR MARKET FOR CLASS A STOCK
 
    Prior to the Offering, there has been no public market for the Class A
Stock. The Company will apply for quotation of the Class A Stock on the Nasdaq
National Market under the trading symbol "AMTD". There can be no assurance that
an active public market will develop or be sustained for the Class A Stock. The
initial public offering price will be determined through negotiations between
the Company, the Selling Stockholders and the representatives of the
Underwriters and may not be indicative of the market price for the Class A Stock
after the completion of the Offering. The market price of the Class A Stock
after completion of the Offering could be subject to significant fluctuations in
response to quarterly variations in operating results, announcements of
technological innovations or new software, services or products by the Company
or its competitors, changes in financial estimates by securities analysts or
other events or factors, many of which are beyond the Company's control. In
addition, the stock market has experienced significant price and volume
fluctuations that have particularly affected the market prices of equity
securities of many technology companies and that often have been unrelated to
the operating performance of such companies. These broad market fluctuations may
adversely affect the market price of the Class A Stock. There can be no
assurance that purchasers of Class A Stock will be able to resell their Class A
Stock at prices equal to or greater than the initial public offering price. See
"Underwriting."
 
DILUTION
 
    Purchasers in the Offering will experience immediate and substantial
dilution in the net tangible book value per share of their investment in the
Class A Stock. See "Dilution."
 
                                       14
<PAGE>
                                USE OF PROCEEDS
 
    The net proceeds to the Company from the Offering are estimated to be
approximately $      million ($      million if the Underwriters' over-allotment
option is exercised in full) assuming an initial public offering price of
$      per share (the mid-point of the estimated range of the initial public
offering price set forth on the cover of this Prospectus) and after deducting
underwriting discounts and commissions and estimated offering expenses. The
Company will not receive any proceeds from the sale of shares of Class A Stock
by the Selling Stockholders. Approximately $4.9 million of the net proceeds to
the Company will be used to repay borrowings under the Company's credit
facility. These borrowings mature through 1999 and bear interest at a variable
rate, which at September 27, 1996 was 9.25%. See "Management's Discussion and
Analysis of Financial Condition and Results of Operation--Liquidity and Capital
Resources--Bank Loan Agreement." The remainder of the net proceeds will be used
to expand the Company's customer base through marketing activities and the
development and acquisition of new forms of technology to be used in the
Company's business. The Company may also use a portion of the proceeds for other
general corporate purposes, including to acquire complementary businesses and to
increase the net capital of AmeriTrade Clearing. See "Risk Factors--Strategic
Acquisitions and Relationships." The Company does not currently have any
agreements with respect to any such acquisitions. Prior to the application of
the net proceeds to the Company as described above, such funds will be invested
in short-term investment grade securities.
 
                                       15
<PAGE>
                                DIVIDEND POLICY
 
    The Company has never declared or paid any cash dividends on its capital
stock and does not anticipate paying any cash dividends to its stockholders in
the foreseeable future. The Company currently intends to retain all future
earnings to finance the continued expansion and operation of its business. The
Company's Certificate of Incorporation provides that any cash dividend declared
must be paid equally on a per share basis on the Class A Stock and the Class B
Stock. See "Description of Capital Stock--Common Stock--Dividend Rights." Any
determination as to the payment of dividends will be made by the Board and will
depend upon the Company's future results of operations, financial condition,
capital requirements and such other factors as the Board considers appropriate.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."
 
                                    DILUTION
 
    The net tangible book value of the Common Stock at September 27, 1996 was
approximately $24.0 million, or $2.99 per share. Net tangible book value per
share is determined by dividing the number of outstanding shares of Common Stock
into the net tangible book value of the Company. After giving effect to the
Offering, the pro forma net tangible book value of the Common Stock at September
27, 1996 would have been approximately $      million, or $      per share. This
represents an immediate increase in the net tangible book value of $      per
share to present stockholders and an immediate dilution of $      per share to
new investors purchasing shares at an assumed initial public offering price of
$      per share. The following table illustrates this per share dilution in net
tangible book value:

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    The following discussion of the financial condition and results of
operations of the Company should be read in conjunction with the Consolidated
Financial Statements and Notes thereto included elsewhere in this Prospectus.
This discussion contains forward-looking statements that involve risks and
uncertainties. The Company's actual results may differ materially from those
anticipated in these forward-looking statements as a result of certain factors,
including, but not limited to, those set forth under "Risk Factors" and
elsewhere in this Prospectus.
 
OVERVIEW
 
    The Company was established in 1971 and has conducted its operations in the
discount brokerage industry since 1975. The Company's consolidated financial
statements include the accounts of AmeriTrade Holding Corporation and its wholly
owned discount brokerage subsidiaries, Accutrade, Aufhauser, Ceres and All
American, and its wholly owned securities clearing subsidiary, AmeriTrade
Clearing. The Company began to provide clearing and execution services for its
own broker-dealer subsidiaries and for independent correspondents in 1983.
Throughout the 1980s, the Company's discount securities brokerage and clearing
and execution businesses experienced significant growth, both in terms of number
of accounts and trading volume. In the 1990s, the Company has continued to grow
and has diversified its services through the formation of Ceres in 1994 and
eBroker in 1996. In July 1995, the Company acquired the net assets of Aufhauser
for approximately $7.6 million in cash. Of the total purchase price, $7.0
million was allocated to goodwill, which is being amortized over a 20 year
period. In October 1995, the Company acquired the net assets of All American for
approximately $0.2 million.
 
    The Company's revenues consist primarily of transaction revenues and
interest revenues. Transaction revenues include brokerage commissions,
securities transaction clearing fees and payments based on order flow. Interest
revenues are generated by charges to customers on debit balances maintained in
brokerage accounts and the investment of cash from operations and cash
segregated in compliance with federal regulations in short-term marketable
securities.
 
    Interest expense consists of amounts paid or payable to customers based on
credit balances maintained in brokerage accounts, as well as costs related to
notes payable, letters of credit and a revolving line of credit with financial
institutions.
 
    The Company's operating expenses include employee compensation and benefits,
commissions and clearing fees related to the processing of securities
transactions, telephone, postage and other communications costs, occupancy and
equipment costs, advertising and promotion costs, provision for losses related
to the processing of securities transactions, and amortization of goodwill
established in connection with the acquisitions discussed above.
 
    In addition, the Company incurs supply costs related to the processing of
customer confirmations, statements and other communications, as well as general
office supply costs, legal costs and regulatory costs. These costs have been
classified as other expenses on the Company's consolidated statements of income.
 
    For the years ended September 27, 1996, September 29, 1995 and September 30,
1994, 67%, 68% and 74%, respectively, of the Company's net revenues were derived
from commissions and clearing fees. Clearing services include the confirmation,
receipt, settlement, delivery and recordkeeping functions involved in the
processing of securities transactions. Included as a part of the clearing
function is the assumption of responsibility for the possession and control of
customer securities and other assets. As a result, the Company records on its
balance sheet amounts receivable from customers that are a result of margin
loans (loans made to customers that are collateralized by securities held in
customers' brokerage accounts at the Company). In addition, the Company records
on its balance sheet amounts payable to its
 
                                       19
<PAGE>
customers and correspondent broker-dealers related to cash balances maintained
by the Company on behalf of those customers and correspondents (free credit
balances).
 
    The Company uses several execution agents to execute its customers' orders
and derives a significant portion of its revenues from these execution agents
for such order flow. The revenues generated by the Company under these
arrangements for the years ended September 27, 1996, September 29, 1995 and
September 30, 1994 were 15%, 11% and 12%, respectively, of net revenues. The
majority of these revenues were received from execution agents owned by
Roundtable Partners, L.L.C. ("Roundtable"), an entity that was approximately
12.1% owned by the Company as of September 27, 1996. Competition between
execution agents has narrowed the spread between bid and ask prices, which has
made it less profitable for execution agents to offer order flow payments to
brokers such as the Company's subsidiaries. The Company expects such payments to
decrease as competition increases; however, the Company has taken steps and
intends to take further steps to mitigate the financial impact of the loss of
these revenues. See "Business--Investments." Nevertheless, there can be no
assurance that the loss of any significant portion of these revenues will not
have a material adverse effect on the Company's business, financial condition
and operating results. See "Risk Factors--Loss of Future Order Flow Payments."
 
    The Company operates in a highly competitive and rapidly expanding market.
As a result, a significant portion of its operating costs are incurred in
connection with advertising and promotional activities. These expenditures
represented 14%, 14% and 22% of operating expenses in the years ended September
27, 1996, September 29, 1995 and September 30, 1994, respectively. The Company's
primary advertising and promotional mediums include print, television, direct
mail, online services and various Internet sites. The Company generally expenses
all advertising and promotional costs as incurred. The Company has increased its
advertising and promotional activities substantially during the first quarter of
fiscal 1997 and intends to maintain a high level of such expenditures during the
remainder of fiscal 1997.

    FISCAL YEARS ENDED SEPTEMBER 27, 1996 AND SEPTEMBER 29, 1995
 
    NET REVENUES.  Commissions and clearing fees increased 52% to $36.5 million
for fiscal 1996 from $24.0 million in fiscal 1995. This increase was primarily
attributable to an increase in the number of securities transactions processed,
as average trades per day increased 79% to 3,670 in fiscal 1996 from 2,055 in
fiscal 1995. The increase in transaction processing volume was primarily a
result of the marketing efforts undertaken by the Company's discount brokerage
subsidiaries, the first full fiscal year of operations of Aufhauser and the
introduction of the Accutrade FOR WINDOWS software in March 1996. The increase
in transactions processed was partially offset by a decrease in average
commission revenue per trade of 15% to $39 in fiscal 1996 from $46 in fiscal
1995, primarily as a result of an increased proportion of trades generated by
Ceres.
 
    Net interest revenue (interest revenue less interest expense) increased 37%
to $11.5 million in fiscal 1996 from $8.4 million in fiscal 1995. This increase
was due primarily to an increase of 42% in cash and investments segregated in
compliance with federal regulations, an increase of 28% in customer and
correspondent broker-dealer receivables and an increase of 42% in amounts
payable to customers and correspondent broker-dealers in fiscal 1996 over fiscal
1995.
 
    Equity income from the Company's investments increased to $3.4 million in
fiscal 1996 from $0.5 million in fiscal 1995, due primarily to the Company's
investment in Roundtable in March 1995.
 
    The Company recorded a fiscal 1995 gain of $0.6 million related to the sale
of its interest in Bond Express, L.P. in August 1995.
 
                                       21
<PAGE>
    Other revenues increased 100% to $3.0 million for fiscal 1996 from $1.5
million for fiscal 1995, due primarily to an increase in marketing fees and
service fees paid to the Company by mutual funds.
 
    EXPENSES EXCLUDING INTEREST.  Expenses associated with employee compensation
and benefits, commissions and clearance, communications, occupancy, equipment
and other costs increased 57% to $27.9 million in fiscal 1996 from $17.8 million
in fiscal 1995, due primarily to the increase in the Company's transaction
processing and customer account maintenance activities.
 
    Advertising and promotion expenses increased 56% to $7.5 million in fiscal
1996 from $4.8 million in fiscal 1995 as the Company increased its advertising
and promotional expenditures in connection with the introduction and promotion
of its Accutrade FOR WINDOWS software in March 1996.
 
    Provision for losses, net of recoveries, was $1.4 million in fiscal 1995,
due primarily to the settlement of a complaint relating to alleged
responsibility for trading losses. See Note 7 to the Consolidated Financial
Statements.
 
    Amortization of goodwill increased to $0.4 million in fiscal 1996 from $0.1
million in fiscal 1995 due to the July 1995 acquisition of Aufhauser.
 
    Income tax expense increased 92% to $7.3 million in fiscal 1996 from $3.8
million in fiscal 1995, consistent with the increase in net income before income
taxes during the same period.
 
    FISCAL YEARS ENDED SEPTEMBER 29, 1995 AND SEPTEMBER 30, 1994
 
    NET REVENUES.  Commissions and clearing fees increased 18% to $24.0 million
for fiscal 1995 from $20.4 million in fiscal 1994. This increase was primarily
attributable to an increase in the number of securities transactions processed,
as average trades per day increased 35% to 2,055 in fiscal 1995 from 1,519 in
fiscal 1994. The increase in transaction processing volume was primarily a
result of the marketing efforts undertaken by the Company's discount brokerage
subsidiaries and the acquisition of Aufhauser in July 1995. The increase in
transactions processed was partially offset by a decrease in average commission
revenue per trade of 12% to $46 in fiscal 1995 from $52 in fiscal 1994,
primarily as a result of an increased proportion of trades generated by Ceres.
In addition, the acquisition of Aufhauser contributed significantly to the 40%
increase in the number of active accounts from 61,665 at September 30, 1994 to
86,431 at September 29, 1995.
 
    Net interest revenue (interest revenue less interest expense) increased 42%
to $8.4 million in fiscal 1995 from $5.9 million in fiscal 1994. This increase
was due primarily to an increase of 24% in cash and investments segregated in
compliance with federal regulations, an increase of 31% in customer and
correspondent broker-dealer receivables and an increase of 27% in amounts
payable to customers and correspondent broker-dealers in fiscal 1995 over fiscal
1994.
 
    Equity income from the Company's investments increased to $0.5 million in
fiscal 1995 from a loss of $0.6 million in fiscal 1994, due primarily to the
Company's investment in Roundtable in March 1995, which generated income of $0.9
million.
 
    The Company recorded a fiscal 1995 gain of $0.6 million related to the sale
of its interest in Bond Express, L.P. in August 1995.
 
    Other revenues decreased 13% to $1.5 million for fiscal 1995 from $1.7
million for fiscal 1994, due primarily to a decrease in transfer and service
fees generated from correspondent broker-dealers.
 
    EXPENSES EXCLUDING INTEREST.  Expenses associated with employee compensation
and benefits, commissions and clearance, communications, occupancy, equipment
and other costs increased 30% to $17.8 million in fiscal 1995 from $13.7 million
in 1994, due primarily to the increase in the Company's transaction processing
and customer account maintenance activities.
 
                                       22
<PAGE>
    Advertising and promotion expenses decreased 20% to $4.8 million in fiscal
1995 from $6.0 million in fiscal 1994 as the Company reduced its advertising and
promotional expenditures related to Accutrade prior to its development and
promotion of its Accutrade FOR WINDOWS software.
 
    Provision for losses, net of recoveries, was $1.4 million in fiscal 1995 due
primarily to the settlement of a complaint relating to alleged responsibility
for trading losses. See Note 7 to the Consolidated Financial Statements.
 
    Amortization of goodwill was $0.1 million in fiscal 1995 due to the July
1995 acquisition of Aufhauser.
 
    Income tax expense increased 45% to $3.8 million in fiscal 1995 from $2.6
million in fiscal 1994, consistent with the increase in net income before income
taxes during the same period.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company has financed its growth primarily through the use of funds
generated from operations. As of September 27, 1996, the Company had $15.8
million in cash and cash equivalents, working capital of $6.4 million and $4.0
million available under its revolving line of credit.
 
    The Company is subject to the requirements of the SEC and the NASD relating
to liquidity, capital standards and the use of customer funds and securities.
The Company has historically operated in excess of the minimum net capital
requirements. See "Business--Government Regulation." The net proceeds from the
Offering will enhance the Company's net capital position, thereby enabling it to
more readily expand its brokerage and clearing businesses. The Company
anticipates that its available cash resources and credit facilities, combined
with the net proceeds from the Offering, will be sufficient to meet its
presently anticipated working capital and capital expenditure requirements for
the foreseeable future based on known and reasonably estimated trends.
 
    OPERATING CASH FLOW
 
    The Company generated $20.9 million in cash from operations in fiscal 1996,
compared to $7.4 million and $2.0 million in fiscal 1995 and 1994, respectively.
The increase in fiscal 1996 was attributable primarily to an increase in
transaction volume related to growth in the discount brokerage operations and
the acquisition of Aufhauser.
 
    Cash used in investing activities was $4.7 million in fiscal 1996, down from
$14.1 million in fiscal 1995 and up from $1.7 million in fiscal 1994. The
significant use of cash in fiscal 1995 related to the purchase of property and
equipment and the acquisition of ownership interests in Aufhauser and Telescan,
Inc. ("Telescan"), as well as increases in the ownership interests of the
Company's investments in Roundtable and Comprehensive Software Systems, Ltd.
("CSS"). Uses of cash in fiscal 1996 related primarily to purchases of property
and equipment and additional investments in Roundtable and CSS, offset by cash
distributions received from Roundtable. See "Business--Investments."
 
    Cash used in financing activities was $2.2 million in fiscal 1996, as
compared to cash provided by financing activities of $7.1 million in fiscal 1995
and cash used of $0.2 million in fiscal 1994. The cash provided in fiscal 1995
was due primarily to term notes payable issued in connection with the Aufhauser
acquisition, and the cash used in fiscal 1996 was due to payments made on those
term notes.
 
    BANK LOAN AGREEMENT
 
    The Company has entered into a Loan Agreement dated as of December 22, 1994
(as amended, the "Bank Loan Agreement") with the First National Bank of Omaha
(the "Bank"). Pursuant to the Bank Loan Agreement, the Company has borrowed a
term loan of $1.9 million payable in monthly installments of principal of
$79,000 beginning January 31, 1995 until January 31, 1997, and a term loan of
$6.0 million payable in monthly installments of principal of $125,000 beginning
August 31, 1995 until July 31, 1999, and
 
                                       23
<PAGE>
may borrow, pay and reborrow up to $4.0 million in revolving loans until January
31, 1997. As of September 27, 1996, the outstanding principal amount of the term
loans was $4.9 million, and there were no outstanding revolving loans. All of
the loans bear interest at the rate designated by the Bank as its regional base
rate, which at September 27, 1996 was 9.25%. The Company has pledged all of the
outstanding stock of AmeriTrade Clearing to the Bank. The Company pays the Bank
an annual commitment fee of 0.5% of the average daily unused amount of the
revolving loans. The Bank Loan Agreement contains various covenants, the more
restrictive requirements being: minimum net capital requirements, minimum net
worth requirements, limitations on incurring additional indebtedness and
limitations on the sale or pledge of capital stock of the Company's subsidiaries
or a substantial part of the Company's assets.
 
    Letters of credit in an aggregate amount of $16.3 million as of September
27, 1996 have been issued on behalf of AmeriTrade Clearing by a financial
institution. These letters of credit, which are for the benefit of securities
clearinghouses, have been issued to support margin requirements. AmeriTrade
Clearing pays a maintenance fee of 0.5% of the committed amount for each letter
of credit. In addition, the same financial institution may make loans to
AmeriTrade Clearing if requested under a note. AmeriTrade Clearing has pledged
customer securities, the amount of which fluctuates from time to time, to secure
its obligations under the letters of credit and the note. As of September 27,
1996, no amounts were outstanding under the note.
 
    CAPITAL EXPENDITURES
 
    The Company's anticipated capital expenditures for fiscal 1997 approximate
$6.0 million, primarily for the purchase of office, computer and other operating
equipment. In addition, at September 27, 1996, the Company had lease commitments
for operating equipment and facilities extending through 2013 in an aggregate
amount of approximately $14.3 million.

OVERVIEW
 
    The Company is a technology and service driven provider of discount
securities brokerage and related financial services. The Company provides retail
brokerage services to individual investors throughout the United States and
internationally through a variety of electronic mediums, including the Internet,
and through registered representatives. The Company offers trade execution for
stocks, mutual funds, options and bonds, as well as market data and research.
The Company also provides clearing and execution services to its own retail
brokerage operations, as well as to independent broker-dealers, depository
institutions, registered investment advisors and financial planners. The Company
had approximately 111,000 active accounts as of September 27, 1996, an increase
from approximately 86,000 active accounts as of September 29, 1995. Average
daily trading volume during the month of October 1996 was approximately 4,200
executed transactions. This compares to an average daily trading volume of
approximately 3,700 executed transactions during fiscal 1996.
 
    The Company has experienced significant growth over the past five years
while expanding profitability. Transaction volumes have increased at an average
annual rate of 45% from fiscal 1992 through fiscal 1996. Net revenues and net
income have grown at average annual rates of 43% and 61%, respectively, over the
same period. These increases, along with the Company's ability to leverage the
use of technology and its aggressive marketing, have resulted in an average
return on equity over the same five-year period of 51% and an operating margin
that has increased from 21% in fiscal 1992 to 34% in fiscal 1996.
 
    The Company's leadership position in the discount brokerage industry is a
result of its unique approach to the delivery of retail brokerage and execution
and clearing services. Retail brokerage services are provided under four
distinct brand names, each of which offers a range of services and commission
rates designed to appeal to specific groups of investors within the discount
brokerage market. Accutrade offers advanced technology delivery systems to
sophisticated investors. Aufhauser provides third-party research and investment
analysis to experienced investors. Ceres offers execution services to customers
who want minimal transaction costs. eBroker provides execution services
exclusively through the Internet. This branding strategy allows the Company to
segment the marketplace, which enables it to align the cost structures of its
discount brokerage businesses with the level of services desired by their
customers. By providing clearing and execution services, the Company is able to
expand its customer base, provide synergies to the Company's retail brokerage
businesses and diversify its revenues.
 
    The Company offers its retail brokerage customers the opportunity to conduct
business through a diversity of electronic mediums, including the Internet,
automated touchtone telephone, personal computer, the Sharp Zaurus personal
digital assistant and facsimile machine. During the quarter ended September 27,
1996, approximately 43% of the Company's transactions were generated through
electronic mediums. The Company also maintains a staff of over 130 registered
representatives to service customers directly. By combining innovative
technology and a range of delivery systems with over 21 years of industry
expertise, the Company is able to provide sophisticated services and efficient
transaction execution while offering commissions that are among the lowest in
the industry. The Company believes that its brokerage commissions are in most
cases substantially lower than those charged by full-commission or traditional
discount brokerage firms for similar transactions.
 
    The Company also provides services to over 70 independent broker-dealers,
depository institutions, registered investment advisers and financial planners
through AmeriTrade Clearing and AmeriVest. AmeriTrade Clearing provides complete
securities transaction clearing and execution services to each of the Company's
discount brokerage businesses, as well as to independent broker-dealers.
AmeriVest provides discount brokerage services to depository institutions that
do not operate their own registered broker-dealers. Providing services to these
correspondents allows the Company to reach investors who rely on more
traditional investment services, such as investment advice, or who prefer to
deal with local or
 
                                       25

regional financial service providers. During the year ended September 27, 1996,
the delivery of financial services to unaffiliated correspondents accounted for
approximately 11% of the Company's net revenues.
 
INDUSTRY
 
    Before 1975, all stock exchanges required brokers to charge fixed minimum
commissions for trades of listed stocks. Under pressure from Congress, the
Department of Justice and the SEC, these policies were changed, which allowed
for negotiated commissions and the unbundling of investment services. These
developments brought about the advent of the discount brokerage firm, which
could separate financial advisory services from execution services, and could
execute trades at a lower cost than a full-commission broker. Although investors
have been able to use discount brokerage services for years, various emerging
trends make the modern investor more likely to use discount brokerage services,
particularly electronic brokerage services.
 
    First, the unbundling of brokerage services from other financial services
has permitted investors to pick and choose among various financial service
providers for specified services. As a result, firms have emerged that provide
the services provided by a full-commission broker on an A LA CARTE basis. Firms
now specialize in investment advice, the provision of financial information and
financial planning. Other firms, like the Company, specialize in providing
securities brokerage services.
 
    Second, consumers have expanded access to powerful, yet inexpensive
technology and are becoming more comfortable with and proficient in the use of
this technology. The use of this new technology to sort and deliver vast amounts
of information, to facilitate inexpensive communication of data and for the
completion of financial transactions has been growing at an accelerating rate.
Specifically, the Internet has produced thousands of new cyber-investors every
day, primarily through the World Wide Web. Forrester Research, Inc. estimates
the number of electronic brokerage accounts will approach 1.5 million by the end
of 1996. Forrester further predicts the number of such accounts will grow to 10
million, carrying $524 billion of assets, by the year 2001, a 46% annual growth
rate.
 
    Third, investors are becoming more self-reliant and value conscious in the
pursuit of their financial goals. Investors are increasingly willing to acquire
the information about, and an understanding of, investment alternatives and have
become increasingly sophisticated and knowledgeable about investing. Access to a
broad range of financial information and advice has decreased the necessity for
full-service brokers. These investors make their own decisions about their
financial future and tend to seek greater value, often in the form of lower
transaction costs. As a result, the use of discount brokers and directly
marketed no-load mutual funds have increased in market share at the expense of
traditional providers charging a higher commission or sales load.
 
    Finally, the growth in financial assets held by an individual is
accelerating. Large numbers of "baby boomers" are beginning to invest for their
children's education and for their own retirement. Additionally, it is estimated
that these individuals, many of whom have greater education, technical
capabilities and investment choices than their parents, as well as greater
access to information, will inherit up to $10 trillion from the previous
generation during the next decade. This represents the largest transference of
wealth in history.
 
    The convergence of these trends is creating a new marketplace for financial
services. It is also creating a new investor, who is self-reliant, comfortable
with the use of technology and value oriented. The Company seeks to be the
leading provider of financial services to this new investor.
 
BUSINESS STRATEGY
 
    The Company seeks to capitalize on the changing financial services industry
and to increase its market share by pursuing the following strategies:

      designed to appeal to specific groups of investors within the discount
      brokerage market. By providing specified services to targeted customers in
      the discount brokerage market, the Company believes that it appeals to a
      broader range of investors seeking brokerage services at discount prices.
      Accutrade provides more technologically advanced solutions than the
      Company's other brands, including program trading and basket trading
      available through Accutrade FOR WINDOWS. Aufhauser is marketed to
      experienced investors seeking research and customer service. Aufhauser

      market with multi-lingual service and with toll-free telephone access from
      36 countries. Ceres is directed at investors who are seeking simple and

      low-priced trade executions. Through this market segmentation approach,
      the Company is able to deliver products and services tailored to the
      specific needs of its customers in the most cost efficient manner. See "--
      Discount Securities Brokerage Services."
 
    - CREATE TECHNOLOGICALLY INNOVATIVE SOLUTIONS TO INVESTOR NEEDS.  The
      Company is a technology leader in the retail brokerage and clearing and
      execution businesses:
 
       - In 1988, the Company was the first broker to implement automated
         touchtone trading technology, which allows customers to place trades
         and obtain quotes electronically using the telephone.
 
       - In 1994, the Company became the first brokerage firm to offer trading
         services over the Internet.
 
       - In 1995, the Company introduced a trading application for the Sharp
         Zaurus personal digital assistant, which allows portable access to
         trades, quotes, positions and balances.
 
       - In 1996, the Company introduced Accutrade FOR WINDOWS, the first online
         investing system that permits individual investors to engage in program
         trading and basket trading.
 
       - The Company recently completed the development and introduction of
         AmeriTrade OnLine, a technologically advanced financial system for its
         correspondents that integrates the products and services of some of the
         world's foremost financial service vendors into one Internet-based
         system.
 
     The Company is actively pursuing additional technologies to service the
     rapidly evolving financial services industry. See "--Strategic
     Relationships" and "Product--Development."
 
    - PROVIDE THE BEST TRANSACTION VALUE TO INVESTORS.  The Company strives to
      offer investors the best transaction values in the financial services
      industry by providing specified services at prices that are among the
      lowest in the industry. eBroker offers a flat $12.00 commission on
      Internet-only trades for an equity order of any size. For investors who
      want access to registered representatives as well as the Internet to place
      trades, Ceres charges a flat $18.00 fee for an equity order of any size.
      Investors desiring more services, such as increased technology, more
      trading options or research, may use Aufhauser or Accutrade. Through more
      efficient operations, an increasing number of transactions and the use of
      advanced technology, the Company strives to minimize costs, which allows
      it to offer some of the best transaction values in the industry.
 
    - EXPAND CLEARING AND EXECUTION SERVICES TO CORRESPONDENTS.  The Company
      intends to continue to leverage the advanced technology offered to its
      retail brokerage customers to increase its clearing and execution business
      with correspondents. Providing clearing and execution services permits the
      Company to expand its customer base by allowing the Company to reach
      investors outside of its targeted retail brokerage markets. Providing
      clearing and execution services for its own broker-

MARKETING
 
    The Company seeks to increase its market share through direct-response
advertising, advertising on its own and other Web sites, a public relations
program and co-marketing. The Company has recently initiated an aggressive
marketing campaign designed to bring greater brand name recognition to the
Company's product lines. As a result, the Company intends to significantly
increase its spending on print, television, radio, direct mail, telemarketing
and online advertising during the current fiscal year. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Overview." From time to time, the Company may choose to increase
spending on advertising to target specific groups of investors or to decrease
advertising expenditures in response to market conditions.
 
    The Company's marketing focuses on advertising its discount brokerage
services as a less expensive and more efficient way of initiating transactions,
building awareness of the Company's product lines and selling the benefits of
the Company's services. Print advertisements are placed in a broad range of
business, technology and financial publications, including THE WALL STREET
JOURNAL, BARRON'S, INVESTOR'S BUSINESS DAILY, FORBES, MONEY and WIRED. Online
advertising is conducted through America Online, CompuServe and popular Web
sites such as Yahoo!, Netscape, Wall Street Journal Interactive and Barron's
Online. The Company advertises regularly on CNBC, CNNFN and other major business
cable television networks. The Company also uses telemarketing and direct mail.
The Company's aggressive advertising program has been a significant contributor
to growth in new accounts. To monitor the efficacy of its various direct
response marketing efforts, the Company has installed sophisticated prospect
tracking and customer acquisition accounting systems.
 
    At the Company's Web sites, prospective customers are able to obtain
detailed information on the Company's services, use an interactive demonstration
system, request additional information and complete an account application
online. Visitors to the Accutrade Web site can periodically participate in a
stock trading game to increase awareness of Accutrade services. The Company
intends to capitalize on the popularity of its Web sites by selling advertising
to third parties who are interested in targeted marketing. In addition, there
are links to home pages of the Company's product lines from more than 750 sites
on the
 
                                       33
<PAGE>
Web. The Company believes that this is a significant factor in increasing brand
awareness and generating leads, as consumers increasingly look to the Internet
as a key source of information and commercial activity. A demonstration of
eBroker's Web site is available on the CD-ROM attached to the inside back cover
page of this Prospectus. Information contained in the Company's Web sites shall
not be deemed to be part of this Prospectus.
 
    The Company pursues public relations opportunities to build brand awareness.
This campaign has resulted in appearances on CNN, CNBC and various local
television stations, in addition to profiles in BUSINESS WEEK and THE WALL
STREET JOURNAL. The Company also actively seeks speaking opportunities at
industry conferences and events. The Company has established a number of
co-marketing alliances to increase brand awareness. For example, the Company has
co-branded Web sites with USA TODAY and Prodigy, which will provide targeted
customers with business and market information. See "--Strategic Relationships."
 
    The Company plans to increase its marketing efforts to attract more
international customers. The Company's customers are currently able to trade
securities online from anywhere in the world. Aufhauser provides multi-lingual
customer service, and toll-free access to Aufhauser is available in 36
countries. The Company has been discussing possible alliances with local
institutions in foreign countries, such as brokers and depository institutions,
to make the portfolio tracking, purchase and sale and funds transfer processes
easier for foreign investors, to facilitate the handling of foreign securities
and to ensure compliance with applicable international laws and regulations.
 
    The Company markets its clearing and execution services primarily through
its direct sales staff. The Company also has booths at trade shows and
advertises in brokerage industry magazines and through AmeriTrade Clearing's Web
site. In addition, the Company has entered into a marketing alliance with Essex,
a leading provider of related financial products to depository institutions. See
"--Strategic Relationships."
 
    All communications by the Company's subsidiaries with the public are
regulated by the NASD. See "--Government Regulation."
 
CUSTOMER SERVICE
 
    The Company strives to optimize the level of customer service provided to
its clients by (i) expanding its use of technology to handle most typical
inquiries generated in the course of customers' securities trading and related
activities, (ii) ensuring adequate staffing with properly trained and motivated
personnel in its customer service departments, enabling prompt response to
customer service calls and (iii) tailoring customer service to the particular
expectations of the clients of each of the Company's brokerage businesses.
 
    The Company's software and Web sites provide basic information on how to use
the Company's services. For those inquiries that cannot be answered through one
of the Company's automated systems, customers are encouraged to use e-mail for
matters that are not time sensitive. The Company's operating standards require a
response within 24 hours of receipt of the e-mail for such matters; however, the
Company strives to respond within 60 minutes of the original message. The
Company also maintains electronic bulletin boards where customers and potential
customers can ask questions and exchange information about the Company's
services. For customers who choose to call or whose inquiries necessitate
calling one of the Company's customer service representatives, the Company is
currently installing advanced call handling capabilities. These systems will
provide automated answering, directing of calls to the proper department,
information about current wait times, summary market data while the customer
waits and the capability to exit the voice queue to leave a voice message for
later response or to transfer to an automated system. The new telephone systems
will also allow linkage between caller identification and the customer database
to give the customer service representative immediate access to the customer's
account data at the time the call is received. It is expected that these
telephone systems will increase call
 
                                       34
<PAGE>
handling efficiency and enhance the customers' experience when calling for
service, particularly during periods of heavy market activity.
 
    The Company recognizes that many of its customers' inquiries require
handling by customer service representatives. The Company strives to provide the
best customer service in the industry as measured by (i) speed of response time
on telephone calls, (ii) turnaround time on resolving customer inquiries and
(iii) customer satisfaction with the account relationship. The Company develops
hiring plans by brand that reflect growth projections for each brand to ensure
that adequate personnel are hired and trained in advance of customer needs.
Customer service representatives receive training in brokerage operations,
Company policies and procedures and basic telephone and clerical skills to
ensure quality and accuracy. Each new representative is monitored closely by a
lead representative, who is supervised by experienced operations managers. All
telephone calls are recorded for purposes of training and supervision and to
assist in the resolution of customer disputes. Hours of service vary by brand,
with all units offering availability at least one hour before and after market
hours.
 
    The Company monitors the speed of answering telephone calls from its
customers. While each of the Company's brokerage businesses establishes its own
target for maximum average wait time before answering, all of them strive to
answer all customer calls in less than one minute. During the month of September
1996, the average answering time at Accutrade, Aufhauser and Ceres was 9.5
seconds. The Company also seeks to monitor the level of overall customer
satisfaction through use of customer response cards sent with trade
confirmations or through periodic surveys. Written comments, e-mails and
electronic postings by customers are regularly reviewed by the Company's senior
officers. It is the Company's policy to respond to all customer questions,
comments or complaints, regardless of the manner received.
 
OPERATIONS
 
    ORDER PROCESSING
 
    Order processing and the resulting trade executions are essential parts of
the delivery of the Company's services. The Company's order processing functions
are performed by AmeriTrade Clearing. AmeriTrade Clearing receives customer
trade orders generated by both its affiliated and independent correspondents
through numerous mediums, including automated touchtone telephone, telephone
calls with registered representatives, proprietary software provided to
customers (e.g., Accutrade FOR WINDOWS), the Internet, online services and
personal digital electronic devices.
 
    Once received, customer orders are subjected to internally developed credit
algorithms to assess the presence of available funds, securities or credit in
the customers' trading accounts. Upon meeting these acceptability criteria,
customer orders are processed by electronically routing the buy or sell orders
to another broker-dealer who is making a market in the security or who
represents AmeriTrade Clearing on the floor of various national stock exchanges.
Over 95% of AmeriTrade Clearing's trades in listed securities are executed by
market making broker-dealers. AmeriTrade Clearing has established redundant
backup electronic links to its primary and secondary execution agents and
maintains flexible routing schedules with these execution agents to assure
timely and best possible execution for its customers.
 
    All listed and over-the-counter ("OTC") market orders without special
qualifiers (subject to certain size limitations based on the order size in the
primary market) are executed at no worse than the National Best Bid/Offer
("NBBO") at the time of receipt by a market making firm or exchange. Eligible
orders are exposed to the marketplace for possible price improvement, but in no
case are orders executed at prices inferior to the NBBO. Limit orders are
executed based on time priority and indicated price. Qualifying limit orders in
OTC securities between the inside market in the Nasdaq quote will be reflected
in the NBBO, creating a new inside quote. This price discovery procedure allows
the Company to execute many orders with the Company's market makers that would
not have been executed by other market making firms.
 
                                       35

    CLEARING
 
    The Company provides clearing and execution services to each of its discount
brokerage businesses, as well as to independent broker dealers, depository
institutions, registered investment advisors and financial planners through its
subsidiary, AmeriTrade Clearing. The clearing function involves a sharing of
responsibilities between the clearing broker and the introducing broker. The
Company's correspondents, as introducing brokers, are responsible for all
customer contact, including opening customer accounts, responding to customer
inquiries and placing customer orders with the clearing broker. As a clearing
broker, AmeriTrade Clearing provides the following back office functions:
maintaining customer accounts; extending credit (in a margin account) to the
customer; settling security transactions with clearing houses (e.g., the
Depository Trust Company and the National Securities Clearing Corporation);
settling commissions and clearing fees; preparing customer trade confirmations
and statements; performing designated cashiering functions, including the
delivery and receipt of funds and securities to or from the customer;
safeguarding funds and securities in customer accounts; transmitting tax
accounting information to the customer and the applicable tax authority;
preparing books and records in support of the above; and other related
transactions.
 
    Included as a part of the clearing function is the assumption of
responsibility for the possession and control of customer securities and other
assets. As a result, the Company records on its balance sheet amounts receivable
from customers that are a result of margin loans (loans made to customers that
are collateralized by securities held in customers' trading accounts at the
Company). In addition, the Company records on its balance sheet amounts payable
to its customers and correspondent broker-dealers related to cash balances
maintained by the Company on behalf of those customers and correspondents (free
credit balances). Clearing operations involve substantial risks of losses due to
errors in performing clearing functions or reporting and clerical errors related
to the handling of customer funds and securities. See "Risk Factors--Clearing
Operations."
 
    AmeriTrade Clearing borrows securities both to cover short sales and to
complete customer transactions in the event that a customer fails to deliver
securities by the required date. AmeriTrade Clearing collateralizes such
borrowings by depositing cash or securities with lending institutions.
Securities borrowing transactions are executed pursuant to written agreements
with counterparties that require that the securities borrowed be "marked to
market" on a daily basis and that excess collateral be refunded or that
additional collateral be furnished in the event of changes in the market value
of the securities. Failure to maintain cash deposit levels at all times at least
equal to the value of the related securities can subject the Company to risk of
loss. See "Risk Factors--Clearing Operations."
 
    MARGIN LENDING
 
    The Company makes loans to customers collateralized by customer securities.
Margin lending by the Company is subject to the margin rules of the Board of
Governors of the Federal Reserve System, NASD margin requirements and the
Company's internal policies, which are more stringent than the Federal Reserve
and NASD requirements. By permitting customers to purchase on margin, the
Company takes the risk of a market decline that could reduce the value of the
collateral held by the Company to below the customers' indebtedness before the
collateral can be sold. See "Risk Factors--Clearing Operations." Under
applicable NASD rules, in the event of a decline in the market value of the
securities in a margin account, the Company is obligated to require the customer
to deposit additional securities or cash in the account so that at all times the
customer's equity in the account is at least 25% of the value of the securities
in the account. The Company's current internal requirement, however, is that the
customer's equity not fall below 30% of the value of the securities in the
account. If it does, the customer will be required to increase the account's
equity to 35% of the value of the securities in the account. These requirements
can be and often are raised as the Company deems necessary for certain accounts,
groups of accounts, securities or groups of securities. The Company is
constantly monitoring customer accounts for these purposes. Margin lending to
customers constitutes the major portion of the basis on which net capital
requirements of the
 
                                       36
<PAGE>
Company are determined under the SEC's Net Capital Rule. To the extent these
activities expand, the Company's net capital requirements will increase. See
"--Government Regulation--Net Capital Requirements; Liquidity."
 
    EXECUTIVE COMMITTEES
 
    The Company has established three executive committees that institute
policies and procedures regarding the Company's daily operations: the Risk
Committee, the Expense Committee and the Operations Committee. Each committee
includes J. Joe Ricketts, Chairman and Chief Executive Officer, Joseph A. Konen,
President and Chief Operating Officer, Robert T. Slezak, Vice President, Chief
Financial Officer and Treasurer, and assigned executives from each of the
Company's subsidiaries. The committees provide oversight and assist the
subsidiaries in achieving their goals. The committees may suggest the
establishment of, or changes to, policies and procedures of the subsidiaries to
strengthen controls in areas of risk, expense and operations. The committees,
however, do not take the place of the decision-making authority vested in each
of the subsidiaries.
 
    The purpose of the Risk Committee is to help protect the Company in the
event a customer (retail customer or correspondent broker) defaults on a payment
obligation to the Company. In addition, the Risk Committee reviews AmeriTrade
Clearing's new and existing correspondents as well as its retail margin
accounts. The Expense Committee is responsible for establishing policies and
procedures for cost control. The Expense Committee reviews each subsidiary's
expenditures to ensure they are in accordance with a pre-approved business plan.
The purpose of the Operations Committee is to design and document systems,
procedures and policies to make daily operations more efficient, and to ensure
that actual operating procedures conform to documented standards.
 
SYSTEMS
 
    The Company uses a variety of systems to support investors and the Company's
correspondents. The Company maintains a sophisticated proprietary computer
network that links the various trading applications to the proprietary core
system, the AmeriTrade Operating System ("ATOS"). All of the customer trading
applications interface and feed data through standardized messaging and
formatting into ATOS. ATOS delivers quotes and information to the investor and
routes trades to the market. ATOS then updates account balances and positions
via multiple lines of communication. ATOS also supports other operations such as
clearing functions, account administration and recordkeeping.
 
    The Company's technology relies on a distributed computer system with an IBM
RISC 6000 backbone. To enhance the reliability of the system and integrity of
data, the Company maintains multiple backup systems. A backup power supply
supports the operations facility. Tape backups are made nightly to prevent a
loss of data.
 
    The Company's technology is supported by an internal staff of programmers,
developers and operators 24 hours a day, seven days a week. The programming
staff is supplemented by a team of quality control analysts, Web page
developers, technical writers and design specialists who ensure the final
product is user-friendly and dependable. In addition to supporting the systems,
the staff continually enhances software and hardware and develops new services.
Software is designed to be versatile and easily adaptable to new and emerging
technologies.
 
COMPETITION
 
    The market for discount brokerage services, particularly electronic
brokerage services, is new, rapidly evolving and intensely competitive. The
Company expects competition to continue and intensify in the future. The Company
encounters direct competition from approximately 100 other discount brokerage
firms, many of which provide electronic brokerage services. These competitors
include such discount brokerage firms as Charles Schwab & Co., Inc., Fidelity
Brokerage Services, Inc., Waterhouse Securities,
 
                                       37
<PAGE>
Inc., Quick & Reilly, Inc. and E*Trade Group, Inc. The Company also encounters
competition from established full-commission brokerage firms as well as
financial institutions, mutual fund sponsors and other organizations, some of
which provide electronic brokerage services. The clearing business is also
highly competitive. AmeriTrade Clearing competes with over 40 clearing firms
that provide clearing and execution services to the securities industry.
 
    The Company believes that the principal competitive factors affecting the
market for its discount brokerage services are price, customer service, quality
of trade execution, delivery platform capabilities, ease of use, graphical user
interface, breadth of services and innovation. Clearing firms compete on the
elements of price, technology, financial strength and customer service. Based on
research conducted with focus groups and the success the Company has enjoyed to
date, the Company believes that it presently competes effectively with respect
to each of these factors.
 
    A number of the Company's competitors have significantly greater financial,
technical, marketing and other resources than the Company. Some of the Company's
competitors also offer a wider range of services and financial products than the
Company and have greater name recognition and more extensive customer bases than
the Company. These competitors may be able to respond more quickly to new or
changing opportunities, technologies and customer requirements than the Company
and may be able to undertake more extensive promotional activities, offer more
attractive terms to customers and adopt more aggressive pricing policies than
the Company. Moreover, current and potential competitors have established or may
establish cooperative relationships among themselves or with third parties to
enhance their services and products. The Company expects that new competitors or
alliances among competitors will emerge and may acquire significant market
share.
 
    The general financial success of companies within the securities industry
over the past several years has strengthened existing competitors. The Company
believes that such success will continue to attract new competitors to the
industry such as depository institutions, software development companies,
insurance companies, providers of online financial and information services and
others. Commercial depository institutions and other financial institutions have
become a competitive factor in the securities industry by offering their
customers certain financial services traditionally provided by brokerage firms.
While it is not possible to predict the type and extent of competitive services
that commercial depository institutions and other financial institutions
ultimately may offer or whether regulatory or legislative barriers will be
repealed or modified, brokerage firms such as the Company may be adversely
affected by such competition or legislation.
 
    There can be no assurance that the Company will be able to compete
effectively with current or future competitors or that the competitive pressures
faced by the Company will not have a material adverse effect on the Company's
business, financial condition and operating results. See "Risk
Factors--Competition."
 
INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS
 
    The Company's success and ability to compete are dependent to a significant
degree on its proprietary technology. The Company relies primarily on copyright,
trade secret and trademark law to protect its proprietary technology. The
Company has several registered and unregistered trademarks, various registered
and unregistered copyrights and certain licenses of technology with third
parties. The Company has no patents. The source code for the Company's
proprietary software is protected both as a trade secret and as a copyrighted
work. It is the Company's policy to enter into confidentiality and
noncompetition agreements with its associates and generally to control access to
and distribution of its proprietary technology.
 
                                       38

GOVERNMENT REGULATION
 
    BROKER-DEALER REGULATION
 
    The securities industry is subject to extensive regulation under federal and
state law. The SEC is the federal agency responsible for administering the
federal securities laws. In general, broker-dealers are required to register
with the SEC under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"). Each of the Company's subsidiaries is a broker-dealer and is
registered with the SEC. Under the Exchange Act, every registered broker-dealer
that does business with the public is required to be a member of and is subject
to the rules of the NASD. The NASD has established Rules of Fair Practice, which
are subject to SEC approval, for all securities transactions among
broker-dealers and private investors, trading rules for the over-the-counter
markets, and operational rules for its member firms. The NASD conducts
examinations of member firms, investigates possible violations of the federal
securities laws and its own rules, and conducts disciplinary proceedings
involving members firms and associated individuals. The NASD administers
qualification testing for all securities principals and registered
representatives for its own account and on behalf of the state securities
authorities.
 
    The Company's subsidiaries also are subject to regulation under state law.
Each of the Company's subsidiaries is registered as a broker-dealer in all 50
states and the District of Columbia. A recent amendment to the federal
securities laws prohibits the states from imposing substantive requirements on
broker-dealers which exceed those imposed under federal law. The recent
amendment, however, does not preclude the states from imposing registration
requirements on broker-dealers that operate within their jurisdiction or from
sanctioning such broker-dealers for engaging in misconduct.
 
    The Company has recently initiated an aggressive marketing campaign designed
to bring greater brand name recognition to the Company's product lines. All
marketing activities by the Company are regulated by the NASD, and all such
marketing materials are required by the NASD to be reviewed by the Company's
compliance officer prior to release. The Company does not currently solicit
orders from its customers or make investment recommendations. However, if the
Company were to engage in such activities, it would become subject to additional
rules and regulations governing, among other things, the suitability of
recommendations to customers and sales practices.
 
    AmeriTrade Clearing is engaged primarily in clearing and settling
transactions effected by other broker-dealers (including the Company's other
subsidiaries). In its capacity as a clearing firm, AmeriTrade Clearing is a
member of the National Securities Clearing Corporation, the Depository Trust
Company and The Options Clearing Corporation, each of which is registered as a
clearing agency with the SEC. As a member of the clearing agencies, AmeriTrade
Clearing is required to comply with the rules of such clearing agencies,
including rules relating to possession and control of customer funds and
securities, margin lending and execution and settlement of transactions.
Participation of AmeriTrade Clearing in these clearing agencies also exposes
AmeriTrade Clearing to certain contingent liabilities. The primary function of
the clearing agencies is to guarantee the settlement of securities transactions
among its members. To ensure that they have the resources available to perform
this guarantee function, the clearing agencies are permitted under their rules
to assess their members on a pro-rata basis in the event of participant default.
In addition, under the rules of the clearing agencies, each member is
responsible for transactions cleared by such member on behalf of its customers.
Accordingly, AmeriTrade Clearing is responsible to the clearing agencies for the
obligations of its customers and must pay or deliver funds or securities to
satisfy its customers' obligations even if it has not received the necessary
funds or securities from its customers.
 
    The Company conducts a significant portion of its business through the
Internet and other electronic media and intends to expand its use of such media.
To date, the use of the Internet has been relatively free from regulatory
restraints. However, the SEC, the SROs and the states are beginning to address
the regulatory issues that may arise in connection with the use of the Internet.
Accordingly, there can be no assurance that these authorities will not adopt new
regulations (or interpret their existing regulations) in a manner which
constrains the Company's ability to transact business through the Internet or
other
 
                                       39
<PAGE>
electronic media. Any additional regulation of the Company's use of electronic
media could render its business or operations more costly, less efficient or
even impossible, any of which could have a material adverse effect on the
Company's business, financial condition and operating results.
 
    NET CAPITAL REQUIREMENTS; LIQUIDITY
 
    As registered broker-dealers and members of the NASD, the Company's
subsidiaries are subject to the Net Capital Rule. The Net Capital Rule, which
specifies minimum net capital requirements for registered brokers-dealers, is
designed to measure the general financial integrity and liquidity of a broker-
dealer and requires that at least a minimum part of its assets be kept in
relatively liquid form. In general, net capital is defined as net worth (assets
minus liabilities), plus qualifying subordinated borrowings and certain
discretionary liabilities, and less certain mandatory deductions that result
from excluding assets that are not readily convertible into cash and from
valuing conservatively certain other assets. Among these deductions are
adjustments (called "haircuts"), which reflect the possibility of a decline in
the market value of an asset prior to disposition.
 
    Failure to maintain the required net capital may subject a firm to
suspension or revocation of registration by the SEC and suspension or expulsion
by the NASD and other regulatory bodies and ultimately could require the firm's
liquidation. The Net Capital Rule prohibits payments of dividends, redemption of
stock, the prepayment of subordinated indebtedness and the making of any
unsecured advance or loan to a stockholder, employee or affiliate, if such
payment would reduce the firm's net capital below a certain level. The Net
Capital Rule also provides that the SEC may restrict for up to 20 business days
any withdrawal of equity capital, or unsecured loans or advances to
stockholders, employees or affiliates ("capital withdrawal") if such capital
withdrawal, together with all other net capital withdrawals during a 30-day
period, exceeds 30% of excess net capital and the SEC concludes that the capital
withdrawal may be detrimental to the financial integrity of the broker-dealer.
In addition, the Net Capital Rule provides that the total outstanding principal
amount of a broker-dealer's indebtedness under certain subordination agreements,
the proceeds of which are included in its net capital, may not exceed 70% of the
sum of the outstanding principal amount of all subordinated indebtedness
included in net capital, par or stated value of capital stock, paid in capital
in excess of par, retained earnings and other capital accounts for a period in
excess of 90 days.
 
    A change in the Net Capital Rule, the imposition of new rules or any
unusually large charge against net capital could limit those operations of the
Company that require the intensive use of capital, such as the financing of
customer account balances, and also could restrict the Company's ability to
withdraw capital from its brokerage subsidiaries, which in turn could limit the
Company's ability to pay dividends, repay debt and repurchase shares of its
outstanding stock. A significant operating loss or any unusually large charge
against net capital could adversely affect the ability of the Company to expand
or even maintain its present levels of business, which could have a material
adverse effect on the Company's business, financial condition and operating
results.
 
    Each of the subsidiaries is a member of Securities Investor Protection
Corporation ("SIPC"), which provides, in the event of the liquidation of a
broker-dealer, protection for customers' accounts held by each of them of up to
$500,000 for each customer account, subject to a limitation of $100,000 for
claims for cash balances. In addition, AmeriTrade Clearing has obtained
$10,000,000 of protection for the benefit of its own broker-dealers and
independent correspondents in excess of SIPC coverage for each account in the
form of an excess securities bond from a private insurance carrier.

    ROUNDTABLE PARTNERS, L.L.C.
 
    Roundtable owns a 99.99% interest in each of Trimark, L.P. ("Trimark") and
Knight Securities, L.P. ("Knight Securities"). Trimark is a third-market trading
operation that makes markets in securities listed on the New York Stock
Exchange, Inc. ("NYSE") and the American Stock Exchange, Inc. Knight Securities

    The Company believes its investment in Roundtable mitigates the risk of
disruption in payment for order flow by giving the Company a significant
investment in the securities trading business. J. Joe Ricketts, Chairman and
Chief Executive Officer of the Company, is a member of the Advisory Committee of
Roundtable.
 
    COMPREHENSIVE SOFTWARE SYSTEMS LTD.
 
    CSS is a limited partnership organized to provide consulting services and to

PROPERTIES
 
    The Company's headquarters are located in Omaha, Nebraska and occupy
approximately 40,000 square feet of leased space. See "Certain Transactions." An
additional 35,000 square feet of space to be leased by the Company is currently
under construction and is expected to be completed in May 1997. The existing
lease expires in December 2013, and upon completion of the addition, the lease
will expire in December 2017. The Company also leases three other locations
totalling approximately 25,000 square feet of space under leases that expire
through August 2001.
 
EMPLOYEES
 
    As of September 27, 1996, the Company employed a total of 334 full-time
associates and 23 part-time associates, of which 139 were registered
representatives. Approximately 85% of the Company's employees have earned at
least a bachelor's degree. The Company believes that its future success will
depend on its continued ability to attract and retain highly skilled and
qualified employees. The Company believes that its relations with its employees
are good.
 
    The Company's employment assessment process is a critical factor in
identifying candidates whose abilities and potential create the opportunity to
be a successful associate with the Company. The assessment process includes an
in-person interview, a work-related behavioral trait profile, a cognitive
reasoning assessment test, a telephone structured interview to identify life
themes predictive of success, and a data entry "keyboarding" or computer skills
test when appropriate. The Company believes that its employment assessment
process has a positive impact on the Company's success.
 
    The Company regularly pays cash bonuses to its management and non-management
employees. Bonuses are based upon the success of the Company and the individual
job performance of the employee.
 
LEGAL PROCEEDINGS
 
    The Company is not aware of any material legal proceedings against the
Company. The Company is involved from time to time in various legal proceedings
and claims incident to the normal conduct of its business.

    Profit Sharing Plan.

    PROFIT SHARING PLAN
 
    The Company maintains the AmeriTrade Holding Corporation Associates Profit
Sharing Plan and Trust (the "Profit Sharing Plan") for the benefit of eligible
employees of the Company and its subsidiaries. Generally, all employees who have
attained age 21 and have completed a year of service are eligible for
participation in the Profit Sharing Plan. For any plan year, the Company may
make a discretionary contribution to the Profit Sharing Plan, which is allocated
to participants employed on the last day of the year based on their compensation
for that year pursuant to a formula integrated with the Social Security taxable
wage base. Participants vest in their account balances in 20 percent increments,
and become fully vested after completing six years of service with the Company.
Generally, distributions from the Profit Sharing Plan are made following
termination of employment. Unless a participant elects periodic payments, during
the first calendar year following termination of employment the amount
distributable is the greater of one-half of the participant's vested account
balance or $50,000, with any remaining portion of such account balance paid in
the next following year. The assets of the Profit Sharing Plan are invested
primarily in Class A Stock. Upon completion of the Offering, the Profit Sharing
Plan will own approximately   % of the Class A Stock.
 
    1996 LONG TERM INCENTIVE PLAN
 
    The Company has adopted the AmeriTrade Holding Corporation 1996 Long Term
Incentive Plan (the "Incentive Plan"). The number of shares which may be awarded
under the Incentive Plan shall not exceed 500,000 shares in the aggregate, no
more than 100,000 shares may be awarded to any one individual in any
 
                                       47
<PAGE>
one-year period and the aggregate cash payout with respect to awards under the
Incentive Plan in any calendar year for any one individual may not exceed $2.5
million. Shares issued under the Incentive Plan may be authorized and unissued
shares of Class A Stock or treasury shares of Class A Stock. In the event of
certain transactions affecting the type or number of outstanding shares of Class
A Stock, the number of shares subject to the Incentive Plan, the number or type
of shares subject to outstanding awards and the exercise price thereof will be
appropriately adjusted. The Incentive Plan will authorize the award of options
to purchase Class A Stock, Class A Stock appreciation rights ("SARs"), awards of
Class A Stock (which may be subject to restrictions) and performance units.
 
    The Incentive Plan shall be administered by a committee of the Board
consisting of two or more non-employee directors appointed to administer the
Incentive Plan (the "Committee"). The Board has designated the Compensation
Committee to act as the Committee. The Committee will determine which employees
of the Company shall be eligible to receive awards under the Incentive Plan, and
the amount, price, timing and other terms and conditions applicable to such
awards; provided, that only the Chief Executive Officer, Chief Operating Officer
and Chief Financial Officer are eligible to receive awards under the Incentive
Plan.
 
    Options awarded under the Incentive Plan may be either incentive stock
options which are intended to satisfy the requirements of Section 422 of the
Internal Revenue Code of 1986, as amended, or nonqualified stock options which
are not intended to satisfy Section 422 of the Code. SARs may be granted in
tandem or otherwise in connection with options or may be granted as
free-standing awards. Exercise of an option will result in the corresponding
surrender of any tandem SAR. The exercise price of an option or SAR may not be
less than the fair market value of a share of Class A Stock on the date on which
the option or SAR is granted. Options and SARs will be exercisable in accordance
with the terms established by the Committee. Options and SARs will expire on the
date determined by the Committee, which shall not be later than the earliest to
occur of (i) the tenth anniversary of the grant date, (ii) the first anniversary
of the participant's termination of employment by reason of death or disability,
(iii) the third anniversary of the participant's termination of employment by
reason of retirement or (iv) the three-month anniversary of the participant's
termination of employment for any other reason. If an SAR is issued in tandem
with an option, the expiration date for the SAR shall be the expiration date for
the related option.
 
    Under the Incentive Plan, the Committee may grant awards of Class A Stock to
participants, which shall be subject to such conditions and restrictions, if
any, as the Committee may determine. During the period a stock award is subject
to restrictions or limitations, the Committee may award the participant dividend
rights with respect to such shares.
 
    The Committee may also award participants performance units, which entitle
the participant to receive value for the units at the end of a performance
period to the extent provided under the award. The number of units and the
performance measures and periods shall be established by the Committee at the
time such award is made.
 
    All awards under the Incentive Plan will accelerate and become fully vested
upon a change in control of the Company.
 
    EXECUTIVE BONUS PLAN
 
    Effective October 1, 1991, the Company adopted an Executive Bonus Plan (the
"Executive Bonus Plan") to allow designated executive participants the
opportunity to earn bonus awards with current and deferred components. The value
of each component is based on the annual increase (if any) in the book value per
share of Common Stock. Not later than October 31 of each plan year, which is the
same as the Company's fiscal year, the Board designates the executives who shall
be participants in the Executive Bonus Plan for such plan year and the
performance guidelines to be used to determine the number of Credits that may be
earned by such participant for such plan year.
 
                                       48
<PAGE>
    On or before November 15 of each plan year, each participant designates
whether the Credits that may be earned for a particular plan year shall vest as
of the last day of such plan year ("Cash Bonus Credits"), the last day of the
fifth plan year commencing after such plan year ("5-Year Credits"), or the
earlier of the last day of the fifth plan year commencing after such plan year
or the participant's attainment of age 55 ("Age-55 Credits"); provided, that no
more than 50% of the Credits for a plan year may be designated as Cash Bonus
Credits. No later than December 31 following the end of each plan year, the
Company credits to each participant's applicable Cash Bonus Credit Account,
5-Year Credit Account or Age-55 Credit Account the number of Credits, if any,
earned for such plan year and allocated by the participant to that Account.
 
    Upon vesting, each Credit entitles the participant to a cash payment equal
to the excess, if any, of the book value of a share of Common Stock on the last
day of the plan year in which Credit vests over the book value of a share of
Common Stock on the last day of the plan year immediately preceding the plan
year with respect to which the Credit was awarded. Such payment is made on or
before the first January 31 occurring after the end of the plan year in which
the Credit vests with respect to the participant. If a participant's employment
with the Company terminates for any reason other than death or disability prior
to the time the participant's Credits become vested, such Credits are forfeited.
Credits become fully vested in the event of the participant's death or
disability. Vesting may be accelerated for any reason in the sole discretion of
the Board.
 
    The Company records all increases in the value of participant accounts in
the year of such increase for all current and deferred Credits. The Company has
recorded expenses in connection with the Executive Bonus Plan of $1,710,000,
$1,105,000 and $544,350 for the years ended September 27, 1996, September 29,
1995 and September 30, 1994, respectively.

addition, either party may terminate any of the Employment Agreements with or

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    The current members of the Compensation Committee are Messrs. Mark L.
Mitchell and Thomas Y. Hartley. Prior to October 1996, there was no Compensation
Committee and the then existing Board participated in decisions regarding
executive officer compensation. During the year ended September 27,
 
                                       49
<PAGE>
1996, no member of the Board served as a director or a member of the
compensation committee of any other company of which any executive officer
served as a member of the Board.
 
    The Company paid $591,040 during each of fiscal 1994, 1995 and 1996 to J.
Joe Ricketts and Marlene M. Ricketts for lease of the Company's headquarters. J.
Joe Ricketts is Chairman and Chief Executive Officer of the Company.
 
    On June 7, 1994, J. Joe Ricketts borrowed $430,000 from the Company, payable
in monthly installments, at an 8.75% interest rate. The remaining outstanding
principal balance of the loan was fully paid on May 7, 1996.
 
    On September 5, 1995, J. Joe Ricketts borrowed $173,000 from the Company,
payable on demand, at a 7.25% interest rate. The remaining outstanding principal
balance of the loan was fully paid on November 19, 1996.
 
                              CERTAIN TRANSACTIONS
 
    The Company has engaged in a variety of transactions with the Ricketts
Family and may continue to engage in similar transactions in the future. The
Company's intention is that all such transactions will be on terms at least as
favorable to the Company as would be obtainable in arms-length dealings with
unrelated third persons. In addition, the fairness and reasonableness of any
compensation paid to the Ricketts Family or their affiliates by the Company and
any material transaction between the Ricketts Family or their affiliates and the
Company in the future will be subject to approval by a majority of the
independent members of the Board or by an independent firm selected by such
members. See "Compensation Committee Interlocks and Insiders Participation."

                          DESCRIPTION OF CAPITAL STOCK
 
    The following description of the Company's authorized capital stock is
subject to the detailed provisions of the Company's Certificate of Incorporation
and Bylaws, copies of which have been filed as exhibits to the Registration
Statement of which this Prospectus is a part.
 
    The authorized capital stock of the Company consists of 25,000,000 shares of
Class A Common Stock, $.01 par value (the "Class A Stock"), 2,000,000 shares of
Class B Common Stock, $.01 par value (the "Class B Stock"), and 3,000,000 shares
of preferred stock, $1.00 par value (the "Preferred Stock"). The Class A Stock
and the Class B Stock are referred to herein as the "Common Stock." At September
27, 1996, there were 7,155,900 shares of Class A Stock outstanding, 852,750
shares of Class B Stock outstanding and no shares of Preferred Stock were
outstanding. After the Offering, there will be       shares of Class A Stock
outstanding (  shares if the Underwriters' over-allotment option is exercised in
full), 852,750 shares of Class B Stock outstanding and no shares of Preferred
Stock outstanding. The additional shares of Common Stock and Preferred Stock may
be utilized for a variety of corporate purposes, including future public
offerings and corporate acquisitions, and could be utilized, under certain
circumstances, to delay, prevent or make more difficult a takeover or change in
control of the Company.
 
COMMON STOCK
 
    VOTING RIGHTS
 
    Except as otherwise required by law and with respect to the election of
directors, the holders of Class A Stock and the holders of Class B Stock have
one vote per share and vote as a single class with respect to all matters
submitted to a vote of stockholders. Under the Delaware General Corporation Law
("DGCL"), any proposal to amend the Certificate of Incorporation to change the
rights, preferences and limitations of Class A Stock must be approved by the
holders of Class A Stock voting separately as a class. The number of directors
shall not be less than three, with the precise number to be determined by
resolution of the Board. The Company currently has six directors. The Class B
Stock is entitled to elect a majority of the directors of the Company. The Class
A Stock is entitled to elect the remaining directors of the Company. Directors
may be removed and vacancies may generally be filled only by the holders of the
class of Common Stock that elected the removed director or that had previously
filled the vacancy. If all of the shares of Class B Stock are converted into
Class A Stock or otherwise cease to be outstanding, the holders of Class A Stock
will be entitled to elect all of the directors, subject to the rights of the
holders of Preferred Stock, if any. Shares of Class A Stock and Class B Stock do
not have cumulative voting rights.
 
    The holders of Class B Stock generally will have the power to defeat any
attempt to acquire control of the Company even though such a change in control
may be favored by stockholders holding substantially more than a majority of the
Company's outstanding shares of Common Stock. This may have the effect of
precluding holders of shares in the Company from receiving any premium above
market price for their shares which may be offered in connection with any such
attempt to acquire control. The holders of Class B Stock through their ability
to control the Board will also generally have the power to prevent certain
fundamental corporate changes, such as a sale of substantially all of the
Company's assets, a merger of the Company, or an amendment to the Company's
Certificate of Incorporation.
 
                                       52
<PAGE>
    DIVIDEND RIGHTS
 
    Each share of Class A Stock is entitled to dividends if, as and when
dividends are declared by the Board. Any dividend declared and payable in cash,
capital stock of the Company (other than Class A Stock or Class B Stock) or
other property must be paid equally on a share for share basis on Class A Stock
and Class B Stock. Dividends and distributions payable in shares of Class A
Stock may be paid only on shares of Class A Stock, and dividends and
distributions payable in shares of Class B Stock may be paid only on shares of
Class B Stock. If a dividend or distribution payable in Class A Stock is made on
Class A Stock, a simultaneous and equivalent dividend or distribution in Class B
Stock must be made on Class B Stock. If a dividend or distribution payable in
Class B Stock is made on Class B Stock, a simultaneous and equivalent dividend
or distribution in Class A Stock must be made on Class A Stock.
 
    CONVERSION RIGHTS
 
    The Class A Stock is not convertible. Each share of Class B Stock is
convertible into one share of Class A Stock at any time at the option of and
without cost to the holder thereof. Each share of Class B Stock shall
automatically convert into one share of Class A Stock in the event such share of
Class B Stock is sold or transferred to any person other than to a member of the
Control Group. In addition, the Class B Stock shall automatically convert on a
share for share basis into Class A Stock if the number of shares of outstanding
Common Stock held by the Control Group falls below 20% of the total number of
shares of outstanding Common Stock.
 
    LIQUIDATION RIGHTS
 
    The holders of the Class A Stock and the holders of the Class B Stock are
entitled to participate equally on a share for share basis in all distributions
to the holders of Common Stock in any liquidation, distribution or winding up of
the Company.
 
    PREEMPTIVE RIGHTS
 
    Neither the holders of Class A Stock nor the holders of Class B Stock have
preemptive rights to purchase shares of such stock or shares of stock of any
other class that the Company may issue.
 
PREFERRED STOCK
 
    The Board of Directors of the Company is authorized to issue, by resolution
and without any action by stockholders, up to 3,000,000 shares of Preferred
Stock and may establish the designations, dividend rights, dividend rate,
conversion rights, voting rights, terms of redemption, liquidation preference,
sinking fund terms and all other preferences and rights of any series of
Preferred Stock, including rights that could adversely affect the voting power
of the holders of Class A Stock. The Company has no present intention to issue
any shares of Preferred Stock.
 
CERTAIN PROVISIONS OF THE CERTIFICATE OF INCORPORATION AND BYLAWS
 
    The Company's Certificate of Incorporation incorporates certain provisions
permitted under the DGCL relating to the liability of directors. These
provisions eliminate the personal liability of its directors to the Company or
its stockholders for monetary damages for any breach of their fiduciary duties
in their capacity as directors, except for any breach of the duty of loyalty,
for acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law, for liability under Section 174 of the DGCL
(relating to certain unlawful dividends, stock repurchases or stock
redemptions), or for any transaction from which the director derived any
improper personal benefit. These provisions do not eliminate a director's duty
of care and do not affect the availability of equitable remedies such as an
action to enjoin or rescind a transaction involving a breach of fiduciary duty.
Moreover, these provisions do not apply to claims against a director for
violation of certain laws, including Federal securities laws. The
 
                                       53
<PAGE>
Company's Bylaws contain provisions to indemnify the directors and officers to
the fullest extent permitted by the DGCL. The Company believes that these
provisions will assist the Company in attracting and retaining qualified
individuals to serve as directors and officers.
 
    The Company's Bylaws establishes procedures, including advance notice
procedures, regarding the nomination of candidates for election as directors and
stockholder proposals. For nominations of directors or other business to be
properly brought by a stockholder before an annual meeting of stockholders, a
stockholder must give notice to the Secretary of the Company of not less than
120 days nor more than 150 days prior to the date of the Company's proxy
statement regarding the preceding year's annual meeting. For nominations or
other business to be properly brought by a stockholder before a special meeting
of stockholders, a stockholder must give notice to the Secretary of not less
than 60 days nor more than 90 days prior to the date of such special meeting. A
special meeting of the stockholders may only be called by the Chief Executive
Officer, the President, the majority of the Board or the holders of not less
than 25% of the outstanding voting stock of the Company. A stockholder may
nominate a person to be a director only if such stockholder would be entitled to
vote for such person in the election for such director. In addition, the notice
of a stockholder nominating a person for director must provide all information
relating to such person as is required by Regulation 14A of the Exchange Act.
 
DELAWARE ANTI-TAKEOVER LAW
 
    Section 203 of the DGCL ("Section 203") restricts certain transactions
between a corporation organized under Delaware law (or its majority-owned
subsidiaries) and any person holding 15% or more of the corporation's
outstanding voting stock, together with the affiliates or associates of such
person (an "Interested Stockholder"). Section 203 prevents, for a period of
three years following the date that a person becomes an Interested Stockholder,
the following types of transactions between the corporation and the Interested
Stockholder (unless certain conditions, described below, are met): (a) mergers
or consolidations, (b) sales, leases, exchanges or other transfers of 10% or
more of the aggregate assets of the corporation, (c) issuances or transfers by
the corporation of any stock of the corporation which would have the effect of
increasing the Interested Stockholder's proportionate share of the stock of any
class or series of the corporation, (d) any other transaction which has the
effect of increasing the proportionate share of the stock of any class or series
of the corporation which is owned by the Interested Stockholder and (e) receipt
by the Interested Stockholder of the benefit (except proportionately as a
stockholder) of loans, advances, guarantees, pledges or other financial benefits
provided by the corporation.
 
    The three-year ban does not apply if either the proposed transaction or the
transaction by which the Interested Stockholder became an Interested Stockholder
is approved by the board of directors of the corporation prior to the time such
stockholder becomes an Interested Stockholder. Additionally, an Interested
Stockholder may avoid the statutory restriction if, upon the consummation of the
transaction whereby such stockholder becomes an Interested Stockholder, the
stockholder owns at least 85% of the outstanding voting stock of the corporation
without regard to those shares owned by the corporation's officers and directors
or certain employee stock plans. Business combinations are also permitted within
the three-year period if approved by the board of directors and authorized at an
annual or special meeting of stockholders by the holders of at least two-thirds
of the outstanding voting stock not owned by the Interested Stockholder. In
addition, any transaction is exempt from the statutory ban if it is proposed at
a time when the corporation has proposed, and a majority of certain continuing
directors of the corporation have approved, a transaction with a party who is
not an Interested Stockholder (or who becomes such with approval of the board of
directors) if the proposed transaction involves (a) certain mergers or
consolida-tions involving the corporation, (b) a sale or other transfer of over
50% of the aggregate assets of the corporation or (c) a tender or exchange offer
for 50% or more of the outstanding voting stock of the corporation.

TRANSFER AGENT AND REGISTRAR
 
    The transfer agent and registrar for Class A Stock is The Bank of New York.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Prior to the Offering, there has been no market for Class A Stock of the
Company. Future sales of substantial amounts of Class A Stock in the public
market, or the perception that such sales may occur, could adversely affect the
market price of the Class A Stock prevailing from time to time in the public
market.
 
    Upon completion of the Offering, the Company will have approximately
shares of Common Stock outstanding (  shares if the Underwriters' over-allotment
option is exercisable in full), including       shares of Class A Stock offered
hereby and 7,697,650 "restricted" shares of Common Stock. The shares of Class A
Stock offered hereby will be freely tradeable without restriction or further
registration under the Securities Act by persons other than "affiliates" of the
Company within the meaning of Rule 144 promulgated under the Securities Act. All
of the 6,844,900 shares of Class A Stock that were outstanding before the
Offering but are not being sold pursuant to the Offering and all 852,750
outstanding shares of Class B Stock may not be sold unless registered under the
Securities Act or sold in accordance with an exemption therefrom, such as Rule
144. In general, under Rule 144 as currently in effect, a person (and persons
whose shares are aggregated with those of such person) who has owned restricted
shares beneficially for at least two years, including an affiliate for purposes
of Rule 144, would be entitled to sell within any three-month period a number of
shares that does not exceed the greater of (i) one percent of the then
outstanding shares of Class A Stock or (ii) the average weekly trading volume of
the Class A Stock during the four calendar weeks preceding the date on which
notice of the sale is filed with the SEC. Sales under Rule 144 are also subject
to certain manner of sale provisions, notice requirements and the availability
of current public information about the Company. Of the 7,697,650 restricted
shares, 7,568,743 shares of Common Stock are currently eligible for sale under
Rule 144 and 128,907 shares of Common Stock will be eligible for sale under Rule
144 beginning in November 1998. Certain employees of the Company purchased
59,462 shares of Class A Stock from J. Joe Ricketts in November 1996. Although
those shares will be eligible for sale under Rule 144 beginning in November
1998, the respective stock purchase agreements between such employees and Mr.
Ricketts prohibit the sale of such shares until May 1999, subject to certain
limited exceptions. In addition, the Company intends to register under the
Securities Act 500,000 shares of Class A Stock under the Incentive Plan. See
"Management--Executive Compensation--1996 Long Term Incentive Plan."
 
    Each of the Company, its directors and officers, the Selling Stockholders
and certain other stockholders has agreed that it will not offer, sell, contract
to sell, announce its intention to sell, pledge or otherwise dispose of,
directly or indirectly, or file with the SEC a registration statement under the
Securities Act relating to, any additional shares of the Company's Class A Stock
or securities convertible into or exchangeable or exercisable for any shares of
the Company's Class A Stock without the prior written consent of CS First Boston
Corporation for a period of 180 days after the date of this Prospectus, except
in the case of the Company, issuances pursuant to the exercise of employee stock
options granted under the Company's existing incentive plans and, in the case of
the directors and officers, Selling Stockholders and certain other stockholders,
gifts and pledges of shares where the donees or pledgees, as the case may be,
agree in writing to be bound by the terms of such agreement. See "Underwriting."

    The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent and that the Underwriters will be
obligated to purchase all of the shares of Class A Stock offered hereby (other
than those shares covered by the over-allotment option described below) if any

default by an Underwriter, in certain circumstances the purchase commitments of
non-defaulting Underwriters may be increased or the Underwriting Agreement may

First Boston Corporation, expiring at the close of business on the 30th day

outstanding shares of Class A Stock from the Company at the initial public
offering price less the underwriting discounts and commissions, all as set forth
on the cover page of this Prospectus. Such option may be exercised only to cover
over-allotments in the sale of the shares of Class A Stock offered hereby. To
the extent such option is exercised, each Underwriter will become obligated,
subject to certain conditions, to purchase approximately the same percentage of
such additional shares of Class A Stock as it was obligated to purchase pursuant
to the Underwriting Agreement.
 
    The Company has been advised by the Representatives that the Underwriters
propose to offer the shares of Class A Stock to the public at the public
offering price set forth on the cover page of this Prospectus and, through the
Representatives, to certain dealers at such price less a concession of $
per share, and the Underwriters and such dealers may allow a discount of $
per share on sales to certain other dealers. After the initial public offering,
the public offering price and concession and discount to dealers may be changed
by the Representatives.
 
    The Representatives have informed the Company that they do not expect
discretionary sales by the Underwriters to exceed 5% of the shares of Class A
Stock being offered hereby.
 
    Each of the Company, its directors and officers, the Selling Stockholders
and certain other stockholders has agreed that it will not offer, sell, contract
to sell, announce its intention to sell, pledge or otherwise dispose of,
directly or indirectly, or file with the SEC a registration statement under the
Securities Act relating to, any additional shares of the Company's Class A Stock
or securities convertible into or exchangeable or exercisable for any shares of
the Company's Class A Stock without the prior written consent of CS First Boston
Corporation for a period of 180 days after the date of this Prospectus, except
in the case of the Company, issuances pursuant to the exercise of employee stock
options granted under the Company's existing incentive plans and, in the case of
the directors and officers, Selling Stockholders and certain other stockholders,
gifts and pledges of shares where the donees or pledgees, as the case may be,
agree in writing to be bound by the terms of such agreement.
 
    At the request of the Company, the Underwriters have reserved for sale, at
the initial public offering price less 60% of the underwriting discount
approximately   % of the shares offered hereby, to directors,
 
                                       56
<PAGE>
officers and employees of the Company and its subsidiaries. The number of shares
available for sale to the general public will be reduced to the extent such
persons purchase such reserved shares. Any reserved shares not so purchased will
be offered by the Underwriters to the general public on the same terms as the
other shares offered hereby.
 
    The Company and the Selling Stockholders have agreed to indemnify the
Underwriters against certain liabilities, including civil liabilities under the
Securities Act, or contribute to payments which the Underwriters may be required
to make in respect thereof.
 
    Application will be made to list the shares of Class A Stock being offered
hereby on the NASDAQ National Market under the symbol "AMTD".
 
    Prior to the Offering, there has been no established trading market for the
Class A Stock. The initial price to the public for the Class A Stock offered
hereby has been determined by negotiation among the Company, the Selling
Stockholders and the Representatives. The factors considered in determining the
initial price to the public include the history of and the prospects for the
industry in which the Company operates, the ability of the Company's management,
the past and present operations of the Company, the historical results of
operations of the Company, the prospects for future operating income and
earnings of the Company and the trends of such operating income and earnings,
the general condition of the securities markets at the time of the Offering and
the recent market prices of securities of generally comparable companies. There
can be no assurance, however, that the prices at which the Class A Stock will
sell in the public market after the Offering will not be lower than the price at
which they are sold by the Underwriters.
 
    Each of the Company's subsidiaries is a member of the NASD. Raymond James &
Associates, Inc. ("Raymond James"), one of the Underwriters, may be deemed to be
an affiliate of the Company. The Offering, therefore, is being conducted in
accordance with the applicable provisions of Schedule E of the By-Laws of the
NASD. Schedule E requires that the initial public offering price of the Class A
Stock not be higher than that recommended by a "qualified independent
underwriter" meeting certain standards. Accordingly, CS First Boston Corporation
is assuming the responsibilities of acting as the qualified independent
underwriter and conducting due diligence. The initial public offering price of
the Class A Stock set forth on the cover page of this Prospectus will be no
higher than the price recommended by CS First Boston Corporation.
 
    Raymond James, together with the Company and certain other investors, is a
limited partner of CSS and a stockholder in its general partner, CSS Management.
See "Business--Investments." Raymond James owns approximately 12.7% of CSS.
Thomas A. James, Chairman of the Board of Directors of Raymond James Financial,
Inc., the sole parent of Raymond James, is a member of the Executive Committee
of CSS and a member of the Board of Directors of CSS Management.
 
SUBSEQUENT RESTRICTIONS
 
    Securities industry regulations prohibit an NASD member firm, after the
completion of a distribution of securities of its parent to the public, from
effecting any transaction (except on an unsolicited basis) for the account of
any customer in, or making any recommendation with respect to, any such
security. Thus, following the Offering, the Company's subsidiaries will not be
permitted to make recommendations regarding the purchase or sale of the Class A
Stock.
 
    Under the Rules of the NASD, if any employee of any of the Company's
subsidiaries, any person associated (as defined in such Rules) with any of the
Company's subsidiaries, or any immediate family member of any such employee or
associated person purchases any of the shares of Class A Stock offered hereby,
such person may not sell, transfer, assign, pledge or hypothecate such shares
for a period of five months following the effective date of the Offering.

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Stockholders of
 
AmeriTrade Holding Corporation and Subsidiaries
 
Omaha, Nebraska
 
    We have audited the accompanying consolidated balance sheets of AmeriTrade
Holding Corporation (formerly, "TransTerra Co.") and its subsidiaries
(collectively, the "Company") as of September 29, 1995 and September 27, 1996,
and the related consolidated statements of income, stockholders' equity and cash
flows for each of the three years in the period ended September 27, 1996. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of AmeriTrade Holding Corporation
and its subsidiaries as of September 29, 1995 and September 27, 1996, and the
results of their operations and their cash flows for each of the three years in
the period ended September 27, 1996 in conformity with generally accepted
accounting principles.

                AMERITRADE HOLDING CORPORATION AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                    FOR THE YEARS ENDED SEPTEMBER 30, 1994,
                   SEPTEMBER 29, 1995 AND SEPTEMBER 27, 1996
 
1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    BASIS OF PRESENTATION--The consolidated financial statements include the
accounts of AmeriTrade Holding Corporation (formerly TransTerra Co.) and its
wholly-owned subsidiaries (collectively, the "Company"), AmeriTrade Clearing,
Inc. (formerly, AmeriTrade, Inc.) ("AmeriTrade Clearing"), Accutrade, Inc.
("Accutrade"), Ceres Securities, Inc. ("Ceres"), K. Aufhauser & Company, Inc.
("Aufhauser"), and All American Brokers, Inc. ("All American"). All significant
intercompany balances and transactions have been eliminated.
 
    On September 27, 1996, the Company's Board of Directors approved a
resolution to reincorporate in the State of Delaware and change its name from
TransTerra Co. to AmeriTrade Holding Corporation. The reincorporation was
accomplished by exchanging each share of Class A and Class B common stock of
TransTerra Co. for thirty shares of Class A and Class B common stock,
respectively of AmeriTrade Holding Corporation. All share data and per share
amounts have been restated to reflect this exchange.
 
    NATURE OF OPERATIONS--AmeriTrade Clearing is a broker-dealer that provides
trade execution and clearing serivces to correspondent broker-dealers.
AmeriTrade Clearing is required to abide by all applicable rules and regulations
of the Securities and Exchange Commission, the Chicago Stock Exchange, Inc. and
the National Association of Securities Dealers. Accutrade, Ceres, Aufhauser and
All American, are broker-dealers that provide discount securities brokerage and
related financial services. Ceres brokerage operations commenced in October
1994. Each of these brokerage companies clears its securities transactions
through AmeriTrade Clearing.
 
    The Company reports on a fifty-two/fifty-three week year.
 
    USE OF ESTIMATES--The preparation of consolidated financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amount of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the consolidated financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.
 
    SECURITIES TRANSACTIONS--Securities transactions are recorded on a
settlement date basis with such transactions generally settling three business
days after trade date. Revenues and expenses related to securities transactions
are also recorded on settlement date, which is not materially different than
trade date.
 
    DEPRECIATION AND AMORTIZATION--Depreciation is provided on a straight-line
basis using estimated useful service lives of five to seven years. Leasehold
improvements are amortized over the lesser of the economic useful life of the
improvement or the term of the lease.
 
    Goodwill is amortized on a straight-line basis generally over a twenty year
period. Accumulated amortization at September 29, 1995 and September 27, 1996
was $154,020 and $517,022, respectively.
 
    EARNINGS PER SHARE--Per share data is determined based on the weighted
average number of common shares outstanding each year.

1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
(CONTINUED)
    INCOME TAXES--The Company files a consolidated income tax return with its
subsidiaries on a calendar year basis. Deferred income taxes are provided for
temporary differences between financial statement and taxable income. The
principal temporary differences arise from depreciation, bad debts, prepaid
expenses, and certain accrued liabilities. Deferred tax liabilities and assets
are determined based on the differences between the financial statement carrying
amounts and tax bases of assets and liabilities using enacted tax rates in
effect in the years in which the differences are expected to reverse.
 
    CASH AND CASH EQUIVALENTS--The Company considers temporary, highly liquid
investments to be cash equivalents.
 
    SEGREGATED CASH AND INVESTMENTS--Cash and investments at AmeriTrade Clearing
of $123,690,789 and $175,668,497 in 1995 and 1996, respectively, have been
segregated in a special reserve bank account for the benefit of customers under
Rule 15c3-3 of the Securities Exchange Act of 1934.
 
    ESTIMATED FAIR VALUE OF FINANCIAL INSTRUMENTS--The Company considers the
amounts presented for financial instruments on the consolidated balance sheets
to be reasonable estimates of fair value. The fair value of the Company's
long-term borrowings, estimated based on current interest rates, does not differ
significantly from the amount recorded at September 27, 1996.
 
    INVESTMENTS--Investments in other companies and partnerships are accounted
for under the equity method when the Company has the ability to exercise
significant influence over the investee's operating and financial policies or
when the investment is a corporate joint venture. The cost method is used for
other investments. All material intercompany balances and transactions are
eliminated in consolidation.
 
    RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS--In March 1995, Statement of
Financial Accounting Standards No. 121, ACCOUNTING FOR IMPAIRMENT OF LONG-LIVED
ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF ("SFAS No. 121") was issued.
SFAS No. 121 establishes the accounting and reporting requirements for
recognizing and measuring impairment of long-lived assets to be either held and
used or held for disposal. The Company does not expect SFAS No. 121 to have a
material effect on its consolidated financial statements.
 
    RECLASSIFICATIONS--Certain items in prior years' consolidated financial
statements have been reclassified to conform to the fiscal 1996 presentation.

    The Company and certain of its subsidiaries lease their office facilities
from the Chief Executive Officer of the Company and his wife. The lease expires
on December 31, 2013, and provides for annual rentals of $591,040. Additionally,
the Company and its subsidiaries lease certain computer equipment, office
equipment, and office facilities under various operating leases. Rental expense
was $834,299, $866,983 and $1,581,171 for fiscal years ended 1994, 1995 and
1996, respectively.
 
    The Company has amended its lease for office facilities to provide for
additional space. The amended lease is for a term of twenty years, and will
provide for annual rentals of $1,288,000. This amended lease is expected to
become effective in 1997.
 
    LETTERS OF CREDIT--Letters of credit in an aggregate amount of $16.3 million
as of September 27, 1996, have been issued on behalf of AmeriTrade Clearing by a
financial institution. These letters of credit, which are for the benefit of
securities clearinghouses, have been issued to support margin requirements.
AmeriTrade Clearing pays a maintenance fee of 0.5% of the committed amount for
each letter of credit. In addition, the same financial institution may make
loans to AmeriTrade Clearing if requested under a note. AmeriTrade Clearing has
pledged customer securities, the amount of which fluctuates from time to time,
to secure its obligations under the letters of credit and the note. As of
September 27, 1996, no amounts were outstanding under the note.
 
    LEGAL--In July 1994, a civil complaint was filed by an Ohio county in U.S.
District Court against Accutrade and AmeriTrade Clearing seeking to recover
approximately $6.5 million of alleged trading losses, plus interest. The
complaint alleged that the treasurer of the county unlawfully invested county
funds through a relative, who allegedly fraudulently caused certain county funds
to be wire transferred from the county to Accutrade and AmeriTrade Clearing into
an account owned by that relative. It was further alleged that the funds were
improperly invested in common stock and options resulting in the trading losses.
A customer account in the name of the county was never maintained at Accutrade
or

7. COMMITMENTS AND CONTINGENCIES (CONTINUED)
AmeriTrade Clearing. In December 1994, this complaint was settled with an out of
court payment of $1.5 million to the Ohio county.
 
    The Company and its subsidiaries are part of a number of other legal matters
arising in the ordinary course of its business. In management's opinion, the
Company has adequate legal defenses respecting each of these actions and does
not believe that they will materially affect the Company's results of operations
or its financial position.
 
    GENERAL CONTINGENCIES--In the general course of business, there are various
contingencies which are not reflected in the consolidated financial statements.
These include AmeriTrade Clearing's customer activities involving the execution,
settlement and financing of various customer securities transactions. These
activities may expose the Company to off-balance-sheet credit risk in the event
the customers are unable to fulfill their contracted obligations.
 
    AmeriTrade Clearing's customer securities activities are transacted on
either a cash or margin basis. In margin transactions, AmeriTrade Clearing
extends credit to the customer, subject to various regulatory and internal
margin requirements, collateralized by cash and securities in the customer's
account. In connection with these activities, AmeriTrade Clearing executes and
clears customer transactions involving the sale of securities not yet purchased
("short sales"). Such transactions may expose AmeriTrade Clearing to off-
balance-sheet risk in the event margin requirements are not sufficient to fully
cover losses which customers may incur. In the event the customer fails to
satisfy its obligations, AmeriTrade Clearing may be required to purchase or sell
financial instruments at prevailing market prices in order to fulfill the
customer's obligations.
 
    AmeriTrade Clearing seeks to control the risks associated with its customer
activities by requiring customers to maintain margin collateral in compliance
with various regulatory and internal guidelines. AmeriTrade Clearing monitors
required margin levels daily and, pursuant to such guidelines, requires the
customers to deposit additional collateral, or to reduce positions, when
necessary.
 
8. ACQUISITIONS
 
    AUFHAUSER--On July 10, 1995, the Company acquired the net assets of K.
Aufhauser & Company, Inc. for $7,582,337 in cash. $7,000,000 of the purchase
price has been allocated to goodwill, which is being amortized over a twenty
year period. The acquisition was accounted for under the purchase method of
accounting and the consolidated financial statements include the results of
operations from the date of acquisition.
 
    ALL AMERICAN--On October 25, 1995, the Company acquired the net assets of
All American Brokers, Inc. for $188,953 in cash. $127,000 of the purchase price
has been allocated to goodwill, which is being amortized over a twenty year
period. The acquisition was accounted for under the purchase method of
accounting and the consolidated financial statements include the results of
operations from the date of acquisition.
 
    The pro forma effects of these acquisitions on the Company's consolidated
financial statements as if they had occurred at the beginning of fiscal years
are not material.

ITEM 17. UNDERTAKINGS.
 
    The undersigned registrant hereby undertakes to provide to the underwriters,
at the closing specified in the underwriting agreement, certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described under Item 14 above, or
otherwise, the registrant has been advised that in the opinion of the SEC such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by a registrant of expenses
incurred or paid by a director, officer or controlling person of such registrant
in the successful defense of any action, suit or proceeding) is asserted against
the registrant by such director, officer or controlling person in connection
with the securities being registered, the registrant will, unless in the opinion
of its counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
it is against public policy as expressed in the Securities Act and will be
governed by the final adjudication of such issue.
 
    The undersigned registrant hereby undertakes that:
 
    (1) For the purpose of determining any liability under the Securities Act,
the information omitted from the form of Prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
Prospectus filed by such registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial BONA FIDE offering thereof.

<PAGE>

powers, full or limited, if any, of the shares of such series and the
designations, preferences and relative, participating, optional or other special
rights and the qualifications, limitations or restrictions thereof.

                                 B. COMMON STOCK

     Except as otherwise provided in this Section B or as otherwise required by
applicable law, all shares of Class A Stock and Class B Stock shall be identical

privileges, subject to the same qualifications, limitations and restrictions.

     1.   VOTING RIGHTS.

          (a)  GENERAL.  Except as otherwise provided in this Section B or
     as otherwise required by applicable law, the holders of Class A Stock
     and the holders of Class B Stock shall vote as a single class and
     shall be entitled to one vote per share on all matters to be voted on
     by the stockholders of the Corporation.

          (b)  ELECTION OF DIRECTORS.  The number of directors shall be

     vote of the majority of the directors (or director) elected by the

     or removal created the vacancy, or in the event that there are no such
     directors, by the vote of the majority of the other directors or by
     the sole remaining director, regardless, in each instance, of any
     quorum requirements set forth in the Bylaws of the Corporation.  Any

     his or her successor has been elected and has qualified.  Any vacancy in
     the office of a director created by the increase in the number of directors
     may be filled by election at the next annual or special meeting of
     stockholders in accordance with Section 1(b) or by the vote of all the
     directors prior to such annual or special meeting of stockholders, in which
     case the directors shall designate which class of stock shall be deemed to
     have elected the director filling such vacancy.

          (e)  ONE CLASS OUTSTANDING.  Notwithstanding anything in this
     Section 1 to the contrary, the holders of Class A Stock shall be

     outstanding, subject in each case to the provisions of any Preferred
     Stock.

     2.   DIVIDENDS.  As and when dividends are declared or paid on the Common
Stock, whether in cash, property or securities of the Corporation, the holders
of Class A Stock and the holders of Class B Stock shall be entitled to
participate in such dividends ratably on a per share basis; provided that if
dividends are declared that are payable in shares of Class A Stock or Class B
Stock, dividends shall be declared that are payable at the same rate on both
classes of stock and any dividends payable in shares of Class A Stock shall be
payable to holders of that class of stock and any dividends payable in shares of
Class B Stock shall be payable to holders of that class of stock.


     3.   CONVERSION.

          (a) CONVERSION OF CLASS A STOCK.  The Class A Stock is not
     convertible.

          (b)  CONVERSION OF CLASS B STOCK.

                    (i)  Each share of Class B Stock may be converted into
               one share of Class A Stock at any time at the option of and
               without cost to the holder thereof.  Any such conversion may
               be effected by any holder of Class B Stock surrendering such
               holder's certificate or certificates representing the Class
               B Stock to be converted, duly endorsed, at the principal
               office of the Corporation or any transfer agent for the
               Class B Stock during normal business hours, together with a
               written notice to the Corporation at such office that such
               holder elects to


                                       -3-
<PAGE>

               convert all or a specified number of shares of Class B Stock and
               stating the name or names in which such holder desires the
               certificate or certificates representing such Class A Stock to be
               issued.  Promptly thereafter, the Corporation shall issue and
               deliver to such holder, or such holder's nominee or nominees, a
               certificate or certificates representing the number of shares of
               Class A Stock to which such holder shall be entitled.  Such
               conversion shall be deemed to have been made at the close of
               business on the date of such surrender and receipt of such notice
               and the person or persons entitled to receive the Class A Stock
               issuable upon such conversion shall be treated for all purposes
               as the record holder or holders of such Class A Stock as of the
               close of business on that date.

                    (ii) Each share of Class B Stock shall automatically
               convert into one share of Class A Stock if the number of
               issued and outstanding shares of Common Stock held by the
               Control Group is less than twenty percent (20%) of the
               aggregate number of issued and outstanding shares of Common
               Stock.

                   (iii) Each share of Class B Stock shall automatically convert
               into one share of Class A Stock in the event such share is sold
               or transferred to any person other than to a member of the
               Control Group.  If any share of Class B Stock is sold or
               transferred to a member of the Control Group who subsequently
               ceases to be a member of the Control Group, each such share shall
               automatically convert into one share of Class A Stock.

                  (iv)   For purposes of this Section 3, "Control Group"
               shall mean J. Joe Ricketts, Marlene M. Ricketts, the lineal
               descendants of J. Joe Ricketts and Marlene M. Ricketts and
               their spouses, and any trust or other person or entity that
               holds Class B Stock for the benefit for any of the
               foregoing.

     4.   LIQUIDATION.  Subject to the provisions of any Preferred Stock, the
holders of Class A Stock and the holders of Class B Stock shall be entitled to
participate ratably on a per share basis in all distributions to the holders of
Common Stock in any liquidation, dissolution or winding up of the Corporation.

     5.   SUBDIVISION, RECLASSIFICATION AND COMBINATION.  The Corporation shall
not subdivide, reclassify or combine any class of Common Stock without at the
same time


                                       -4-
<PAGE>

making a proportionate subdivision, reclassification or combination of each
other class of Common Stock.

     SECTION 5.     CLOSING OF TRANSFER BOOKS OR FIXING OF RECORD DATE.  For the

stockholders, or stockholders entitled to receive payment of a dividend, the

any stockholder during the whole time of the meeting.

     SECTION 7.     QUORUM.  The holders of a majority of the outstanding shares
of the Corporation entitled to vote on any matter, represented in person or by
proxy, shall constitute a quorum for consideration of such matter at any meeting
of stockholders; provided that if less than a majority of the outstanding shares
are represented at said meeting, a majority of the shares so represented may
adjourn the meeting at any time without further notice.  If a quorum is present,
the affirmative vote of the majority of the shares represented at the meeting
shall be the act of the stockholders, unless the vote of a greater number or
voting by classes is required by the General Corporation Law of the State of
Delaware (as now in effect or as amended from


                                       -2-

time to time, the "Act"), the Certificate of Incorporation or these bylaws.  At
any adjourned meeting at which a quorum shall be present, any business may be
transacted which might have been transacted at the original meeting.  Withdrawal
of stockholders from any meeting shall not cause failure of a duly constituted
quorum at that meeting.

     SECTION 8.     PROXIES.  At all meetings of stockholders, a stockholder may
vote by proxy executed in writing by the stockholder or by his or her duly
authorized attorney-in-fact.  Such proxy shall be filed with the Secretary of

prepaid.  The attendance of a director


                                       -3-
<PAGE>

at any meeting shall constitute a waiver of notice of such meeting, except where
a director attends a meeting for the express purpose of objecting to the
transaction of any business because the meeting is not lawfully called or
convened.  Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the Board of Directors need be specified in the
notice or waiver of notice of such meeting.

     SECTION 6.     QUORUM.  Unless otherwise provided in the Certificate of

meeting at any time without further notice.

     SECTION 7.     MANNER OF ACTING.  The act of the majority of the directors

Certificate of Incorporation or these bylaws.

     SECTION 8.     PRESUMPTION OF ASSENT.  A director of the Corporation who is
present at a meeting of the Board of Directors at which action on any corporate
matter is taken shall be conclusively presumed to have assented to the action
taken unless his or her dissent shall be entered in the minutes of the meeting
or unless he or she shall file his or her written dissent to such action with
the person acting as the secretary of the meeting before the adjournment thereof
or shall forward such dissent by registered or certified mail to the Secretary
of the Corporation immediately after the adjournment of the meeting.  Such right
to dissent shall not apply to a director who voted in favor of such action.

     SECTION 9.     RESIGNATION OF DIRECTORS.  A director may resign at any time
upon written notice to the Board of Directors, its chairman, if any, or to the
Chief Executive Officer, the President or Secretary.

election at the next annual or special meeting of stockholders or by a majority
of the Board of Directors prior to such annual or special meeting of
stockholders.

     SECTION 11.    REMOVAL OF DIRECTORS.  One or more of the directors may be
removed, with or without cause, at a meeting of stockholders by the affirmative
vote of the holders of a majority of the outstanding shares then entitled to
vote at an election of directors, except that no director shall be removed at a
meeting of stockholders unless the notice of such meeting shall state that a
purpose of the meeting is to vote upon the removal of one or more directors
named in the notice, and then only the named director


                                       -4-

any committee of the Board of Directors may participate in and act at any
meeting of the Board or such committee through the use of a conference telephone

the meeting can hear each other.  Participation in such meeting shall constitute
attendance and presence in person at the meeting of the person or persons so
participating.

     SECTION 13.    INFORMAL ACTION BY DIRECTORS.  Any action required to be
taken at a meeting of the Board of Directors, or any other action which may be
taken at a meeting of the Board of Directors, or of any committee thereof, may
be taken without a meeting if a consent in writing, setting forth the action so
taken, shall be signed by all the directors entitled to vote with respect to the
subject matter thereof, or by all the members of such committee, as the case may
be, and filed with the minutes of the Board or committee.  Any such consent
signed by all the directors or all the members of the committee shall have the
same effect as a unanimous vote, and may be stated as such in any document filed
with the Secretary of State or with anyone else.

     SECTION 14.    COMMITTEES.  A majority of the Board of Directors may by
resolution create one or more committees and appoint members of the Board to
serve on any one or more of such committees.  Each committee shall have two or

committee shall constitute a quorum and a majority of a quorum shall be
necessary for committee action.  Each committee, to the extent provided by the
Board of Directors in such resolution, shall have and exercise all of the
authority of the Board of Directors in the management of the Corporation,
subject to any restriction contained in the Act.  Vacancies in the membership of
any committee shall be filled by the Board of Directors.  Each committee shall
keep regular minutes of its proceedings and report the same to the Board when
requested.  A committee may act by unanimous consent in writing without a
meeting and, subject to action by the Board of Directors, each committee, by a
majority vote of its members, shall determine the time and place of meetings and
the notice therefor.

     SECTION 15.    COMPENSATION.  The Board of Directors, by the affirmative
vote of a majority of directors then in office, and irrespective of any personal
interest of any of its members, shall have authority to establish reasonable
compensation of all directors for services to the Corporation as directors,
officers or otherwise, notwithstanding any director conflict of interest.   By
resolution of the Board of Directors, the directors may be paid their expenses,
if any, of attendance at each meeting of the Board.  No such payment previously
mentioned in this Section 15 shall preclude any


                                       -5-

be accepted in order to be effective.

     SECTION 3.     REMOVAL.  Any officer elected or appointed by the Board of

the proxy statement as a nominee and to serving as a director if elected); (ii)
as to any other business that the stockholder proposes to bring before the
meeting, a brief description of the business desired to be brought before the
meeting, the reasons for conducting such business at the meeting and any
material interest in such business of such stockholder and the beneficial owner,
if any, on whose behalf the proposal is made; and (iii) as to the stockholder

they appear on the Corporation's books, and of such beneficial owner, and (2)

beneficially and of record by such stockholder and such beneficial owner.

     SECTION 4.     DETERMINATION OF COMPLIANCE.  The Chairman of the meeting of
stockholders shall have the power and duty to determine whether a nomination or
any business proposed to be brought before the meeting was made in accordance
with the procedures set forth in this Article V and, if any proposed nomination

defective nominations or proposal shall be disregarded.

                                   ARTICLE VI

                                 INDEMNIFICATION

     Each person who at any time is or shall have been a director or officer of
this Corporation shall be indemnified by the Corporation and shall be entitled
to advancement of expenses by the Corporation in accordance with and to the full
extent permitted by the Act.  The foregoing right of indemnification and
advancement of expenses shall not be deemed exclusive of any other rights to
which a person seeking indemnification may be entitled under any bylaw,
agreement, vote of stockholders or disinterested directors or otherwise.  If
authorized by the Board of Directors, the Corporation may purchase and maintain
insurance on behalf of any person to the full extent permitted by the Act.

                                   ARTICLE VII

                            SHARES AND THEIR TRANSFER

     SECTION 1.     SHARES REPRESENTED BY CERTIFICATES AND UNCERTIFICATED
SHARES.  The issued shares of the Corporation shall be represented by
certificates or shall be uncertificated shares.


                                      -10-

     Certificates representing shares of the Corporation, if any, shall be
signed by or in the name of the Corporation by the Chief Executive Officer, the
President or a Vice President and by the Treasurer or an Assistant Treasurer or
the Secretary or an Assistant Secretary of the Corporation.  Where a certificate
is countersigned by a transfer agent, other than the Corporation or an employee
of the Corporation, or by a registrar, the signatures of the Chief Executive
Officer, the President or a Vice President and the Treasurer or an Assistant
Treasurer or the Secretary or an Assistant Secretary may be facsimiles.  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, the
certificate may be issued by the Corporation with the same effect as if such
officer, transfer agent or registrar were such officer, transfer agent or
registrar at the date of its issue.  Each certificate representing shares shall
be consecutively numbered or otherwise identified, and shall also state the name
of the person to whom issued, the number and class of shares (with designation
of series, if any), the date of issue, and that the Corporation is organized
under Delaware law.  If the Corporation is authorized to issue shares of more
than one class or of series within a class, the certificate shall also contain
such information or statement as may be required by the Act.

     Unless prohibited by the Certificate of Incorporation, the Board of
Directors may provide by resolution that some or all of any class or series of
shares shall be uncertificated shares.  Any such resolution shall not apply to
shares represented by a certificate until the certificate has been surrendered
to the Corporation.  Within a reasonable time after the issuance or transfer of
uncertificated shares, the Corporation shall send the registered owner thereof a
written notice of all information that would appear on a certificate.  Except as
otherwise expressly provided by law, the rights and obligations of the holders
of uncertificated shares shall be as identical to those of the holders of
certificates representing shares of the same class and series.

     The name and address of each stockholder, the number and class of shares
held and the date on which the shares were issued shall be entered on the books
of the Corporation.  The person in whose name shares stand on the books of the
Corporation shall be deemed the owner thereof for all purposes as regards the
Corporation.

     SECTION 2.     TRANSFER OF SHARES.  Transfer of shares of the Corporation
shall be recorded on the books of the Corporation. Transfer of shares
represented by a certificate, except in the case of a lost or destroyed
certificate, shall be made upon surrender for cancellation of the certificate
for such shares.  A certificate presented for transfer must be duly endorsed and
accompanied by proper guaranty of signature and other appropriate assurances
that the endorsement is effective.  Transfer of an uncertificated share shall be
made on receipt by the Corporation of an instruction from the registered owner
or other appropriate person.  The instruction shall be in writing or a
communication in such form as may be agreed upon in writing by the Corporation.


                                      -11-

     SECTION 3.     REPLACEMENT.  In case of the loss, destruction, mutilation
or theft of a certificate for any stock of the Corporation, a new certificate of
stock or uncertificated shares in place of any certificate therefor issued by
the Corporation may be issued upon satisfactory proof of such loss, destruction,
mutilation or theft and upon such terms as the Board of Directors may prescribe.
The Board of Directors may in its discretion require the owner of the lost,
destroyed, mutilated or stolen certificate, or his legal representative, to give
the Corporation a bond, in such sum and in such form and with such surety or
sureties as it may direct, and/or to indemnify the Corporation against any claim
that may be made against it with respect to the certificate alleged to have been
lost, destroyed, mutilated or stolen.

                                  ARTICLE VIII

                                     GENERAL

     SECTION 1.     FISCAL YEAR.  The fiscal year of the Corporation shall be
fixed by resolution of the Board of Directors.

     SECTION 2.     SEAL.  The corporate seal shall have inscribed thereon the
name of the Corporation and the words "Corporate Seal, Delaware."  The seal may
be used by causing it or a facsimile thereof to be impressed or affixed or in
any other manner reproduced, provided that the affixing of the corporate seal to
an instrument shall not give the instrument additional force or effect, or
change the construction thereof, and the use of the corporate seal is not
mandatory.

     SECTION 3.     CONTRACTS.  The Board of Directors may authorize any officer
or officers, agent or agents, to enter into any contract or execute and deliver
any instrument in the name of and on behalf of the Corporation, and such
authority may be general or confined to specific instances.

     SECTION 4.     WAIVER OF NOTICE.  Whenever any notice is required to be
given under the provisions of the Act, the Certificate of Incorporation or these
bylaws, a waiver thereof in writing, signed by the person or persons entitled to
such notice, whether before or after the time stated therein, shall be deemed
equivalent to the giving of such notice.  Attendance at any meeting shall
constitute waiver of notice thereof unless the person at the meeting objects to
the holding of the meeting because proper notice was not given.

                                   ARTICLE IX

                                   AMENDMENTS

     Unless otherwise provided in the Certificate of Incorporation, these bylaws
may be adopted, amended or repealed by the stockholders or the Board of
Directors.

determined and maintained from the inception of the Partnership strictly in
accordance with the rules set forth in Section 1.704-1(b)(2)(iv) of the Treasury

those Regulations and this definition.  By way of illustration and not
limitation, each Partner's Capital Account shall initially equal the cash and
the fair market value of property (net of liabilities secured by such
contributed property assumed or to which the property is subject) contributed by
a Partner to the Partnership, and during the term of the Partnership shall be
(A) increased by the amount of (1) Net Profit or items thereof as allocated to
the Partner, other than Net Profit or items thereof attributable to the
difference between the fair market value and adjusted basis of the property at
contribution, and (2) any money and the fair market value of property (net of
any liabilities secured by such contributed property assumed or to which the
property is subject) subsequently contributed to the Partnership and, (B)
decreased by the amount of (1) Net Loss or items thereof allocated to the
Partner, except (a) Net Loss or items thereof attributable to depreciation of
contributed property, which shall decrease Capital Accounts to the extent of
depreciation computed as if the property were purchased by the Partnership at
its fair market value, and (b) Net Loss attributable to the difference between
the fair market value and adjusted basis of property at contribution (which
shall not decrease the contributing Partner's Capital Account), and (2) all cash
and the fair market value of property (net of liabilities secured by such
distributed property assumed or to which the property is subject) distributed to
such Partner.

          2.4  CAPITAL CONTRIBUTION shall mean the amount of money or value of
property contributed to the capital of the Partnership by a Partner pursuant to

shall mean the minimum gain of the Partnership computed strictly in accordance
with the principles of Section 1.704-2(b)(2) of the Treasury Regulations issued
under the Code.

          Subject to the previous sentence, "Minimum Gain" means an amount of
gain that would be realized by the Partnership on the disposition of Partnership
property subject to non-recourse indebtedness equal to the amount by which such
non-recourse indebtedness exceeds the adjusted tax basis of such property.  For
this purpose, where the asset is subject to multiple secured liabilities, the
allocation rules of Treasury Regulations Section 1.704-2(d)(2) shall apply.  If
Partnership property subject to one or more Nonrecourse Liabilities of the
Partnership is, under Treasury Regulations Section 1.704-1(b)(2)(iv)(d) or
(b)(2)(iv)(f), properly reflected on the books of the Partnership at a book
value


                                        4

that differs from the adjusted tax basis of such property, the determination of

trust, estate, partnership, joint venture, association, company, corporation or
other entity of whatever nature.

that point in time when the back office and order management modules of the
software being developed by the Partnership are deliverable and usable (as
determined in the reasonable judgment of the Board of Directors of the General
Partner ("Software Completion")) and have been installed, as evidenced by the
commencement and clearing of live trades using such software, by 50% of the
Brokers who elect to install such software within sixty (60) days after such
determination by the Board of Directors, and a definitive schedule for
installation of the software with the remaining Brokers (each such Broker shall
have up to six (6) months after such determination by the Board of Directors to
elect to install such software) has been adopted by the Board of Directors of
the General Partner (no later than 30 days from the end of six months after such
determination), provided however, if such schedule is not adhered to by the
Partnership (other than for reasons within the control of one or more Brokers or
by reason of governmental restrictions, strikes or scarcity of labor or
material, or for other reasons beyond the control of the Partnership),
immediately upon the failure to adhere to the schedule, Project Completion shall
be deemed not to have occurred and all of the provisions hereof applicable to
the period prior to Project Completion shall again be effective.

thereafter during which Project Completion remains attained in accordance with
the definition thereof contained in Section 2.18 hereof.

          4.2  ALLOCATION OF NET PROFIT AND NET LOSS. Subject to Sections 4.3,
4.4 and 4.5 hereof, Net Profit and Net Loss shall be allocated among the
Partners in accordance with the Sharing Ratios set forth in Section 4.1.

          4.3  ALLOCATION OF MINIMUM GAIN. In the event that there is a net
decrease in the Minimum Gain of the Partnership during a Partnership taxable
year, each Partner shall be allocated items of Partnership income and gain in
accordance with Treasury Regulation Section 1.704-2(f)(1) for such year (and, if
necessary, for subsequent years) in an amount equal to such Partner's share of
such net decrease of Partnership Minimum Gain. For this purpose, a Partner's
share of the net decrease in Partnership Minimum Gain shall be determined under
Treasury Regulation Section 1.704-2(g)(2). This Section 4.3 is intended to
comply with Treasury Regulation Section 1.704-2(f)(1) and shall be interpreted
consistently therewith.

          4.4  QUALIFIED INCOME OFFSET. In the event any Partners unexpectedly
receive any adjustments, allocations, or distributions described in Treasury
Regulation Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Partnership
income and gain shall be specially allocated to such Partners in an amount and
manner sufficient to eliminate the deficit balances in their Capital Accounts
created by such adjustments, allocations, or distributions as quickly as
possible. Any special allocations of items of income or gain pursuant to this
Section shall be taken into account in computing subsequent allocations of
profits pursuant to this Section, so that the net amount of any items so
allocated to each Partner pursuant to this Section shall, to the extent
possible, be equal to the net amount that would have been allocated to each such
Person pursuant to the provisions of this Section if such unexpected
adjustments, allocations or distributions had not occurred.

          The Partners intend that the provision set forth in this Section will
constitute a "Qualified Income Offset" as described in Section 1.704-
1(b)(2)(ii)(d) of the Treasury Regulations. The regulations shall control in the
case of any conflict between those regulations and this section.

          4.5  ALLOCATIONS FOR CONTRIBUTED PROPERTY. In accordance with Code
Section 704(c) and the Treasury Regulations thereunder, income, gain, loss, and
deduction with respect to any property contributed to the capital of the
Partnership shall, solely for tax purposes, be allocated among the Partners in a
manner consistent with Code Section 704(c) and the Treasury Regulations
thereunder.


                                        8

<PAGE>



          In the event the fair market value of any Partnership property is
adjusted due to a distribution of property, admission of a new Partner,
termination of the Partnership or otherwise, subsequent allocations of income,
gain, loss, and deduction with respect to such asset shall be allocated among
the Partners in the same manner consistent with Code Section 704(c) and the
Treasury Regulations thereunder.

          4.6  DISTRIBUTIONS OF DISTRIBUTABLE CASH. Any Distributable Cash shall
be distributed to the Partners in accordance with the Sharing Ratios set forth
in Section 4.1 at such times and in amounts as determined by the Board of
Directors of the General Partner, in its discretion; provided that all
Distributable Cash on hand shall be distributed at least annually within one
hundred twenty (120) days after the expiration of each fiscal year of the
Partnership. Notwithstanding any other provision hereof, if the Partnership
reports any taxable income for any fiscal year, the Partnership shall distribute
sufficient cash distributions to its Limited Partners so that they would be able
to pay federal, state and local income taxes with such distributions on such
income at the highest effective rate that any Limited Partner is subject to for
such fiscal year. The Board of Directors of the General Partner may from time to
time also allow a Partner to withdraw Distributable Cash from the Partnership,
without concurrent distributions to other Partners in accordance with the
Sharing Ratios, if agreed to in writing by all Partners. Such draws shall be
repaid to the Partnership from future distributions of Distributable Cash to the
Partner.

          4.7. CURATIVE ALLOCATIONS. If the General Partner determines, after
consultation with counsel, that the allocation of any item of Partnership
income, gain, loss, deduction or credit is not specified in this Article IV (an
"unallocated item"), or that the allocation of any item of Partnership income,
gain, loss, deduction or credit hereunder is clearly inconsistent with the
Partners' economic interests in the Partnership (determined by reference to the
general principles of Temp. Reg. Section 1.704-1T(b)(4)(iv), Treas. Reg.
Section 1.704-1(b) and the factors set forth in Treas. Reg. Section 1.704-
1(b)(3)(ii)) (a "misallocated item"), then the General Partner may allocate such
unallocated items, or reallocate such misallocated items, to reflect such
economic interests.

                                      13



<PAGE>

subject to use and confidentiality restrictions in this Agreement or other 
agreements with the Partnership.

     5.5 DISTRIBUTIONS.  Each Partner shall look solely to the assets of the 
Partnership for all Distributions and share of Net Profit or Net Loss, and 
shall have no recourse therefor (upon dissolution or otherwise) against any 
General Partner or Limited Partner, except, however, that this limitation 
shall not impair the right of the Partnership to enforce its rights against a 
Partner under Sections 5.6, 6.1 or 10.4 hereof. No Partner shall have any 
right to demand or receive property other than money upon dissolution and 
termination of the Partnership.

     5.6  LIMITATION ON LIABILITY OF GENERAL PARTNERS; INDEMNIFICATION.

     (a) The General Partner and its directors, officers, employees and 
agents who are entitled to indemnification from the General Partner in 
connection with performing services on behalf of the Partnership 
("Indemnitee"), shall not have any liability, responsibility, or 
accountability in damages or otherwise to any Partner or the Partnership for 
any loss suffered by the Partnership which arises out of any act or omission 
performed or omitted by such Indemnitee in good faith and within the scope of 
the authority granted to it by this Agreement and in the best interest of the 
Partnership; PROVIDED that such act or omission did not constitute gross 
negligence, misconduct or any knowing violation of any statute, law or 
regulation by such Indemnitee. Such Indemnitee shall be indemnified by the 
Partnership and the Partnership hereby agrees to indemnify, pay, protect, and 
hold harmless such Indemnitee (on the demand of and to the satisfaction of 
such Indemnitee) from and against any and all liabilities, obligations, 
losses, damages, actions, judgments, suits, proceedings, costs, expenses and 
disbursements of any kind or nature (provided that the same were not the 
result of gross negligence, misconduct or any knowing violation of any 
statute, law or regulation on the part of the Indemnitee) including, without 
limitation, all reasonable legal fees, costs and expenses of defense, appeal 
and settlement of any and all suits, actions or proceedings instituted 
against such Indemnitee and all costs of investigation in connection 
therewith (collectively referred to as "Liabilities" for the remainder of 
this Section 5.6) that may be imposed on, incurred by, or asserted against an 
Indemnitee in any way relating to or arising out of, any action or inaction 
on the part of such Indemnitee. Notwithstanding the foregoing, an Indemnitee 
shall be liable, responsible and accountable, and the Partnership shall not 
be liable to any such Indemnitee for any portion of such Liabilities, that 
resulted from such Indemnitee's own gross negligence, misconduct or any 
knowing violation of any statute, law or regulation.  Subject to Section 
5.6(c) hereof, if any action, suit or proceeding shall be pending

                                      14
<PAGE>

or threatened against the General Partner relating to or arising, or alleged 
to relate or arise out of any such action or nonaction, such General Partner 
shall have the right to employ separate counsel of its choice in such action, 
suit or proceeding and the reasonable fees and expenses of such counsel shall 
constitute costs, expenses, and disbursements for the purposes of the 
indemnification provided by this Section 5.6.

     The satisfaction of the obligations of the Partnership under this 
Section 5.6(a) shall be from and limited to the assets of the Partnership and 
no Partner shall have any personal liability on account thereof.

     (b) The Partnership shall not incur the cost of that portion of any 
insurance which insures any Indemnitee for any liability as to which such 
Indemnitee is prohibited from being indemnified under this Section 5.6.

     (c) Advances from Partnership funds to an Indemnitee for legal expenses 
and other costs incurred as a result of any legal action initiated against an 
Indemnitee by a Limited Partner of the Partnership in his capacity as such is 
prohibited. Except as provided in the foregoing sentence, advances from 
Partnership funds to an Indemnitee for legal expenditures and other costs 
incurred as a result of any initiated suit, action or proceeding is 
permissible if (i) such suit, action or proceeding relates to or arises out 
of, or is alleged to relate to or arise out of, any action or inaction on the 
part of the Indemnitee in the performance of its duties or provision of its 
services on behalf of the Partnership; (ii) such suit, action or 
proceeding is initiated by a third party who is not a Limited Partner, and 
(iii) the Indemnitee undertakes to repay any funds advanced pursuant to this 
Section 5.6(c) in cases in which such Indemnitee would not be entitled to 
indemnification under Section 5.6(a). If advances are permissible under this 
Section 5.6(c), the Indemnitee shall furnish the Partnership with an 
undertaking as set forth in the foregoing sentence and shall thereafter have 
the right to bill the Partnership for, or otherwise request that the 
Partnership pay, at any time and from time to time after such Indemnitee has 
become obligated to make payment therefor, any and all amounts for which such 
Indemnitee has determined in good faith that such Indemnitee is entitled to 
indemnification under this Section 5.6. The Partnership shall pay any and all 
such bills and honor any and all such requests for payment for which the 
Partnership is liable as determined above. In the event that a final 
determination is made by the Board of Directors of the General Partner that 
the Partnership is not so obligated in respect to any amount paid by it, such 
Indemnitee will refund such amount, plus interest thereon at the then 
prevailing market rate of interest, within 60 days of such final 
determination, and in the event that a final determination is made

                                      15
<PAGE>

by the Board of Directors of the General Partner that the Partnership is so 
obligated in respect to any amount not paid by the Partnership to such 
Indemnitee, the Partnership will pay such amount to such Indemnitee.

     5.7  REIMBURSEMENT OF EXPENSES.

     (a) Except as otherwise set forth herein, all of the Partnership's 
expenses shall be billed directly to and paid by the Partnership. The General 
Partner shall be reimbursed for the actual cost to the General Partner of 
goods, materials and services used for and by the Partnership. The General 
Partner shall be reimbursed for the administrative services necessary to the 
prudent operation of the Partnership at the General Partner's actual cost.

     The General Partner shall not be reimbursed by the Partnership for the 
following expenses:

            (i) Services for which the General Partner is entitled to 
compensation in the form of a separate fee; and

            (ii) Any expenses that are unrelated to the business of the 
Partnership.

     (b) Subject to Section 5.7(a), the Partnership shall pay all expenses of 
the Partnership and all reasonable expenses of the General Partner relating 
to the Partnership which may include, but are not limited to: (i) all costs 
of borrowed money, taxes, and assessments on Partnership property and other 
taxes applicable to the Partnership;  (ii) legal, audit, accounting, and 
other fees; (iii) printing and other expenses and taxes incurred in 
connection with the issuance, distribution, transfer and recording of 
documents evidencing ownership of an interest in the Partnership or in 
connection with the business of the Partnership; (iv) fees and expenses paid 
to independent contractors, bankers, brokers, servicers, leasing agents and 
consultants; (v) the cost of insurance as required in connection with the 
business of the Partnership; (vi) expenses of revising or amending the 
Partnership Agreement, converting, modifying or terminating the Partnership; 
(vii) the costs and expenses incurred in qualifying the Partnership to do 
business in any jurisdiction, including fees and expenses of any resident 
agent appointed by the Partnership; (viii) the costs incurred in connection 
with any litigation or regulatory proceedings in which the Partnership is 
included and (ix) the costs, salaries, benefits, bonuses, employment taxes, 
and expenses incurred, paid borne or reimbursed by the General Partner to all 
employees and officers of the General Partner.

     5.8  TAX STATUS OF PARTNERSHIP.  The General Partner shall use its best 
efforts to meet such requirements of the Code,

                                      16
<PAGE>

as interpreted from time to time by the Internal Revenue Service, necessary 
to assure that the Partnership will be classified as a partnership for 
federal income tax purposes.

                                  ARTICLE VI
                  RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS

     6.1  NO ASSESSMENTS.  Except as specifically provided herein, or as 
otherwise provided by law, no Limited Partner shall be personally liable for, 
or bound by, any expenses, liabilities or obligations of the Partnership.

     6.2  NO RIGHT TO MANAGE.  No Limited Partner shall take part in, or 
interfere in any manner with, the management, control, conduct or operation

the Partnership.

     6.3  DEATH OR DISABILITY OF LIMITED PARTNERS.  The Partnership shall not 
be dissolved by the death, insanity, adjudication of incompetency,

substitute Limited Partner.

     6.4  CONSENT OF LIMITED PARTNERS.  The General Partner may from time to 
time seek the consent of the Limited Partners on any matters not inconsistent 
with the provisions of the Act. Such consent may be obtained by a written 
consent or by the vote of the Limited Partners at a meeting where a majority 
of the Sharing Ratios of Limited Partners are represented in person or by 
proxy after at least 30-days written notice to all Limited Partners. Any 
consent or vote shall be subject to the provisions of Section 5 of the 
Shareholder Agreement. A majority of Sharing Ratios voted for or consenting 
to a proposal of the General Partner will, unless otherwise provided herein 
or in another agreement among all the Limited Partners, evidence the consent 
of the Limited Partners, provided however that the General Partner shall not 
take any of the following actions without the consent of two-thirds of the 
Sharing Ratios of the Limited Partners:

     (a) The sale of all or substantially all of the assets of the 
Partnership pursuant to a single transaction or series of related 
transactions, except for sales in connection with the liquidation and winding 
up of the Partnership business upon its dissolution,

                                  ARTICLE VII

         TRANSFERS BY LIMITED PARTNERS AND ADDITIONAL LIMITED PARTNERS

     7.1    TRANSFER. A Limited Partner may not transfer (a transfer, for 
purposes of this Agreement, shall be deemed to include, but not be limited 
to, any sale, assignment, pledge, creation of a security interest or other 
disposition, whether voluntary or involuntary), in whole or in part, any of 
its interest in the Partnership pursuant to this Agreement, unless, in 
addition to the conditions in Section 11.13 and this Article VII, such 
transfer complies with the applicable provisions of the Shareholder Agreement 
(so long as such provisions have not been terminated) and the following terms 
and conditions have been satisfied:

     (a)    The transferee shall have: (i) assumed all costs incurred by the 
Partnership in connection with the transfer; (ii) at the request of the 
General Partner, furnished the Partnership with an opinion of counsel, 
satisfactory in form and substance to counsel for the Partnership, that such 
transfer complies with applicable federal and state securities laws and this 
Agreement and that such transfer, for federal income tax purposes, will not 
cause the termination of the Partnership, cause the Partnership to be treated 
as an association taxable as a corporation or otherwise adversely affect the 
Partnership or the Partners; and (iii) complied with such other conditions as 
the General Partner may require from time to time;

     (b)    The transferee shall have at the request of the General Partner, 
acknowledged in writing that the transferee's interest in the Partnership 
interest to be transferred is and shall continue to be subject and 
subordinate to any security interest then existing of the Partnership in such 
Partnership interest;

     (c)    The General Partner shall have consented in writing to the 
transfer, which consent may be withheld or given in the sole discretion of 
the General Partner.

     Transfers will be effective and recognized by the Partnership only as of 
the close of business on the last day of the calendar month following 
satisfaction of the above conditions, and the transferor shall cease to be a 
Partner as of that day. Any transfer in contravention of this Article VII and 
any transfer which if made would cause a termination of the Partnership for 
federal income tax purposes (even if the General Partner has

                                      18

<PAGE>

consented to such transfer) shall be void and ineffectual and shall not bind 
the Partnership.

     7.2 RIGHT OF FIRST REFUSAL.

     (a)    As long as Section 12 of the Shareholder Agreement or any 
successor provision has not been terminated, such Section 12 shall govern 
transfers of the interests of Limited Partners and shall supersede this 
Section 7.2. Any Limited Partner other than Comprehensive Securities Systems, 
Inc. ("a Broker") may transfer any portion of its Partnership interest to any 
Affiliate of it without compliance with this Section 7.2. Comprehensive 
Securities Systems, Inc. ("Employee Co.") shall not transfer any portion of 
its Partnership interest to Affiliates except in accordance with the terms of 
this Section 7.2.

     (b)    If a Limited Partner shall receive a bona fide offer in writing 
(a "Bona Fide Offer") from a party which, in the case of Brokers only, is not 
an Affiliate of such Limited Partner and which is financially responsible (a 
"Prospective Purchaser") to purchase all and not less than all of the 
Partnership interest of that Limited Partner for cash (or cash equivalents) 
payable in full at closing, which Bona Fide Offer is subject to no 
contingencies (other than those imposed by this Section 7.2) and such Limited 
Partner is not in default under the Shareholder Agreement, this Agreement or 
its License Agreement and desires to accept such Bona Fide Offer, then the 
Limited Partner that received the Bona Fide Offer (the "Selling Limited 
Partner"), in the manner set forth in this Section 7.2, shall first offer to 
sell its Partnership interest to the other Limited Partners (the "Offerees") 
for a consideration and on terms equivalent to those to which the Selling 
Limited Partner would be entitled if it accepted the Bona Fide Offer. For the 
purposes of this Agreement, the term Bona Fide Offer shall mean a written 
offer which is honest in fact, not collusive and, to the best knowledge of a 
Limited Partner receiving such offer, not a sham.

     (c)    The Selling Limited Partner shall give written notice (an "Offer 
Notice") to each of the Offerees of its receipt of the Bona Fide Offer and 
its offer to sell its Partnership interest at the price and on the material 
terms set forth therein, enclosing with such Offer Notice a complete and 
correct copy of the Bona Fide Offer setting forth all of the terms thereof.

     (d)    If an Offeree or any Affiliate of the Offeree that the Offeree 
may designate shall desire to exercise the right to purchase pursuant to 
subsection (b) of this Section 7.2 (an "Accepting Offeree"), then it shall do 
so in accordance with the following provisions:

                                      19

<PAGE>

         (i)    such Accepting Offeree shall give written notice thereof 
    to the Selling Limited Partner and the other Offerees within 30 days 
    after the Offer Notice was given and, if an Affiliate of such Offeree 
    is to effect the purchase, the Offeree shall guarantee the 
    performance of such Affiliate;

         (ii)   each Accepting Offeree, except for Employee Co., that 
    gives notice of the exercise of the right to purchase shall be 
    obligated to purchase that portion of the Partnership interest being 
    offered by the Selling Limited Partner which is in the proportion 
    that its Sharing Ratio immediately prior to such purchase bears to 
    the aggregate Sharing Ratios of all Brokers who are then Limited 
    Partners, and if Employee Co. is an Accepting Offeree, it shall be 
    obligated to purchase, if at all, all of the Partnership interest of 
    the Selling Limited Partner, however, if Employee Co. is not the only 
    Accepting Offeree, it shall have no rights to purchase any portion of 
    the Project Interest of the Selling Limited Partner, except as 
    provided in clause (iv) below;

         (iii)  if not all of the Selling Limited Partner's Partnership 
    interest is committed for by Accepting Offerees pursuant to clause 
    (ii) above, the Selling Limited Partner shall give another written 
    notice (the "Second Offer Notice") only to the Accepting Offerees, 
    within 45 days after the Offer Notice was given, stating the amount 
    of its Partnership interest that remains uncommitted (the "Excess 
    Amount");

         (iv)   if any Accepting Offeree (including Employee Co.) is 
    willing to commit to purchase any of the Excess Amount (an "Excess 
    Accepting Offeree"), it shall give written notice to the Selling 
    Limited Partner within 60 days after the Offer Notice was given, 
    stating the additional Partnership interest it is willing to commit 
    to purchase, and if such commitments total more than the Excess 
    Amount, the Excess Amount shall be allocated for purchase among the 
    Excess Accepting Offerees in proportion to the respective Excess 
    Amounts they were willing to purchase, provided, however, that if all 
    the Excess Amount can be purchased by Brokers who are Excess 
    Accepting Offerees, then Employee Co., if it is an Excess Accepting 
    Offeree, shall not purchase any of the Excess Amount; and


         (v)    the closing of a purchase of a Selling Limited Partner's 
    interest pursuant to this Section 7.2(d) shall be held at a mutually 
    acceptable place on a mutually acceptable date not more than the 
    later of 60 days after the date the Offer Notice was given or 45 days 
    after the date the Second Offer Notice was given, if it was in fact 
    given; PROVIDED, HOWEVER, that if one or more Accepting Offerees fail 
    to tender its share of the purchase price therefor at the closing, 
    then

                                      20

<PAGE>

    each of the nontendering Accepting Offerees shall lose its rights 
    under this Section 7.2(d) and the tendering Accepting Offerees shall 
    be provided an additional 30 days in which to tender payment for the 
    Selling Limited Partner's interest. At any such closing, the 
    Accepting Offerees shall tender payment to the Selling Limited 
    Partner, and the Selling Limited Partner shall assign to the 
    Accepting Offerees, the Partnership interest to be sold, free and 
    clear of all liens, claims and encumbrances (other than those 
    necessary to finance such sale), and shall execute such documents as 
    may be necessary to effectuate the sale.

     (e)    In the event that (i) no offer to sell made pursuant to Section 
7.2(b) has been accepted on or prior to the 31st day after the Offer Notice 
was given in accordance with Section 7(d)(i) above, (ii) if no Second Offer 
Notice is given, the 60-day period referred to in Section 7.2(d)(v) (subject 
to extension in accordance with Section 7.2(d)(v)) shall lapse without the 
Accepting Offerees having tendered payment in accordance with Section 7(d)(i) 
and (v) above, or (iii) the 45-day period referred to in Section 7.2(d)(v) 
(subject to extension in accordance with Section 7.2 (d)(v)) shall lapse 
without the Accepting Offerees having tendered payment (the first to occur of 
the events referred to in clauses (i), (ii) and (iii) being herein referred 
to as the "Free to Sell Date"), then the Selling Limited Partner shall have 
the right to sell all but not less than all of its Partnership's interest to 
the Prospective Purchaser at the price (or a greater price) and upon the terms 
specified in the Bona Fide Offer, subject to the terms of the other 
subsections of this Section 7.2. The Selling Limited Partner's right to sell 
its Limited Partner's interest to the Prospective Purchaser pursuant to this 
Section 7.2 shall expire and the full restrictions of this Section 7.2 shall 
be reinstated in the event that the Prospective Purchaser has not purchased 
such Partnership interest within 90 days after the Free to Sell Date.

     (f)    A Selling Limited Partner does not waive whatever claims or 
remedies it may have in law or equity against an Accepting Offeree that 
elects to purchase and wrongfully fails to so purchase the Selling Limited 
Partner's interests. The Accepting Offerees that tender payment under the 
circumstances described in Section 7.2(d)(v) do not waive whatever claims or 
remedies they may have in law or equity against any nontendering Accepting 
Offeree.

     7.3    EFFECT OF TRANSFER. If a transfer of a Limited Partner's interest 
has become effective pursuant to Sections 7.1 or 7.2, but the transferee is 
not substituted as a Limited Partner pursuant to Section 7.4 hereof, the 
transferee shall be entitled, as though a Limited Partner, to receive 
Distributions in the manner provided in Article IV, but shall have no other 
rights by virtue of

                                      21
<PAGE>

such transfer, and the transferor shall remain primarily liable for 
Subsequent Capital Contributions hereunder. Unless otherwise agreed by such 
transferee who does not become a substituted Limited Partner, such transferee 
shall not be liable for the obligations of such Limited Partner but the right 
of any such transferee to receive distributions or other payments shall be 
subject to set-off to the same extent that such Limited Partner would have 
been subject to set-off. Notwithstanding any other provisions of this 
Agreement, the Partnership shall be entitled to treat the transferor of a 
Limited Partner's interest as the absolute owner thereof, and shall incur no 
liability by reason of distributions of cash or other property made in good 
faith to such transferor, until such time as the transfer has been accepted 
by the General Partner and registered on the books of the Partnership.

     7.4  SUBSTITUTION OF LIMITED PARTNERS.  A transferee of a Limited 
Partner's interest shall have the right to be substituted as a Limited 
Partner if and only if:

     (a)  The transferee delivers to the General Partner a written notice, 
executed and acknowledged by the transferee and by the transferor, requesting 
that the transferee be substituted as a Limited Partner;

     (b)  All Partners consent in writing to such substitution;

     (c)  The transferee executes, acknowledges and delivers to the General 
Partner instruments in form and substance satisfactory to the General Partner 
accepting and adopting the terms, provisions, appointments and agreements set 
forth in this Agreement and assuming the obligations, if any, of the 
transferor to the Partnership;

     (d)  The opinions, acknowledgements and assumptions referred to in 
Section 7.1 are furnished to the General Partner; and

     (e)  The transferor and/or transferee agree to pay the out-of-pocket 
costs incurred by the Partnership, including legal fees, in connection with 
such substitution.

     7.5  ACQUIT PARTNERSHIP.  In the absence of compliance with the terms of 
this Article and written notice to the Partnership of any transfer of a 
Partnership interest, any payment to the assigning Partner shall acquit the 
Partnership of liability to the extent of such payment to any other Person 
who may have an interest in such payment by reason of a transfer by the 
Partner.

                                      22

     7.6  ADDITIONAL LIMITED PARTNERS.  Subject to Section 10 of the 
Shareholder Agreement, additional Persons may be admitted to the Partnership 
as Limited Partners and Partnership interests may be created and issued to 
those Persons and to existing Partners if approved by the General Partner and 
all of the Limited Partners on such terms and conditions as the General 
Partner and the Limited Partners may determine at the time of admission. The 
terms of admission or issuance must specify the Sharing Ratios applicable to 
the new Partnership interests and to the existing Partners; the effect, if 
any, on Capital Contributions of the Partners; and may provide for the 
creation of different classes or groups of Limited Partners having different 
rights, powers, and duties. The General Partner shall reflect the creation of 
any new class or group in an amendment to this Agreement indicating the 
different rights, powers, and duties, and such an amendment need be executed 
only by the General Partner.

                                 ARTICLE VIII

         ASSIGNMENT, WITHDRAWAL AND SUBSTITUTION OF GENERAL PARTNER

     8.1  ASSIGNMENT OF GENERAL PARTNER'S INTEREST.

     (a)  The General Partner may without any consent or approval, assign, 
mortgage, pledge, encumber or otherwise dispose of any of such General 
Partner's right to receive distributions or other payments with respect to 
its Partnership interests from the Partnership, but such action shall not 
cause the withdrawal of the General Partner nor cause the transferee to 
become substituted as a General Partner, unless such withdrawal and 
substitution is approved as required by this Article. The General Partner 
shall remain liable for its obligations hereunder and, unless otherwise 
agreed by such transferee who does not become a substituted General Partner, 
such transferee shall not be liable for the obligations of such General 
Partner or of the Partnership, but the right of any such transferee to 
receive distributions or other payments shall be subject to set-off to the 
same extent that such General Partner would have been subject to set-off.

     (b)  Any Person receiving all or part of the Partnership interest of a 
General Partner as a result of transfer by operation of law, whether by 
death, bankruptcy or otherwise, shall, subject to the terms of this 
Agreement, receive only such General Partner's rights to receive 
distributions or other payments from the Partnership, and shall not become a 
substituted General Partner (unless substituted as a General Partner pursuant 
to this Article). The Person receiving such Partnership interest shall have 
the same status as a transferee under subsection (a).

                                      23

<PAGE>

     8.2  WITHDRAWAL.  A General Partner may not withdraw or retire from the 
Partnership without the consent of all of the Limited Partners. Any General 
Partner who with the consent of all of the Limited Partners withdraws or 
retires shall cease to be a Partner as of the close of business on the last 
day of the calendar month in which such consent is obtained.

     8.3  SPECIAL LIMITED PARTNERS.  Upon the occurrence of an Event of 
Withdrawal, a General Partner with respect to which such event has occurred, 
or his legal representative as the case may be, shall become a Special 
Limited Partner. A Special Limited Partner shall have no responsibility for, 
and no right to participate in, the management of the Partnership business, 
but shall retain his rights with respect to his Capital Contributions, Net 
Profits and Net Losses, and Distributions as if he had remained a General 
Partner, subject to any set-off or other claim which the Partnership may have.

     8.4  ADMISSION OF ADDITIONAL OR SUCCESSOR GENERAL PARTNER.  A Person 
shall be admitted or substituted as an additional or successor General 
Partner of the Partnership only if each of the following conditions is 
satisfied:

     (a)  the admission or substitution of such Person shall have been 
consented to or ratified by all of the Partners excluding Special Limited 
Partners under Section 8.3 hereof;

     (b)  such Person shall have accepted and agreed to be bound by the terms 
and provisions of this Agreement, by executing a counterpart hereof, and such 
other documents or instruments as may be required or appropriate in order to 
effect the admission of such Person as a General Partner shall have been 
filed for recording, and all other actions required by law in connection with 
such admission shall have been performed;

     (c)  if such Person is a corporation, it shall have provided the 
Partnership with evidence satisfactory to counsel for the Partnership of its 
authority to become a General Partner and to be bound by the terms and 
provisions of this Agreement; and

     (d)  counsel for the Partnership shall have rendered an opinion to the 
Partnership that the admission of such Person as a General Partner is in 
conformity with the Act and that none of the actions taken in connection with 
the admission of such Person is in violation of the Act, shall impair the 
limited liability of the Limited Partners, shall cause the termination or 
dissolution of the Partnership for tax purposes or otherwise, shall cause the 
Partnership to be classified other than as a partnership, (including as a 
publicly-traded partnership) for federal income tax purposes or shall violate 
federal or state securities laws.

     8.5  FAILURE TO ADMIT SUBSTITUTE GENERAL PARTNER.  In the event a 
substitute General Partner has not been admitted within a reasonable time 
after the occurrence of an Event of Withdrawal with respect to the General 
Partner (which "reasonable time" shall in no event be more than 90 days), and 
as a result there is no General Partner then acting, the Partnership shall be 
dissolved, terminated and liquidated as of such date, as provided in Article 
X.

                               ARTICLE IX

                               ACCOUNTING

     9.1  BOOKS AND RECORDS.  The Partnership's books and records, a list of 
the full name and last known business address of each Partner, copies of the 
Partnership's federal, state and local tax returns and reports, if any, and 
financial statements, for the three (3) most recent years, this Agreement and 
all amendments thereto, and all Certificates, together with executed copies 
of any power of attorney pursuant to which any Certificate has been executed, 
shall be maintained at the office of the Partnership and shall be open to 
inspection and, upon payment of costs, to copying by the Partners or their 
duly authorized representatives at all reasonable times.

     9.2  BOOKS OF ACCOUNT.  The General Partner shall, for income tax 
purposes, keep and maintain, or cause to be kept and maintained, adequate

     9.4  TAX RETURNS.  The Tax Matters Partner, at Partnership expense, 
shall cause income tax returns for the Partnership to be prepared and timely 
filed with the appropriate authorities.

     9.5  TAX MATTERS PARTNER.  The General Partner shall be the "tax matters 
partner" of the Partnership pursuant to Section 6231(a) (7) of the Code. The 
General Partner shall take such action as may be necessary to cause each 
other Partner to become a "notice partner" within the meaning of section 6223 
of the Code. The General Partner shall inform each other Partner of all 
significant matters that may come to its attention in its capacity as tax 
matters partner by giving notice thereof within seven days after becoming 
aware thereof, and, within that time, shall forward to each other Partner 
copies of all significant written communications it may receive in that 
capacity. The General Partner may take an action contemplated by sections 
6222 through 6232 of the Code only with the consent of the Limited Partner, 
but

financial statements (balance sheet, statement of income or loss and 
statement of cash flows) prepared in accordance with generally accepted 
accounting principles, except as noted therein, and within ninety (90) days 
after the expiration of each fiscal year of the Partnership, at Partnership 
expense, (a) Partnership information necessary for the preparation of the 
Partners' income tax returns (including a copy of the Partnership's federal, 
state and local income tax returns, if any) and (b) annual audited financial 
statements (balance sheet, statement of income or loss and statement of cash 
flows) prepared in accordance with generally accepted accounting principles 
consistently applied, accompanied by a report of a nationally recognized firm 
of independent public accountants engaged at the direction of the Executive 
Committee of the Board of Directors of the General Partner containing the 
favorable opinion of such accountants to that effect. The officers of the 
Partnership shall also cause to be prepared annual summaries of Partnership 
operations, and such other information on the Partnership's operations and 
conditions as the Executive Committee of the Board of Directors of the 
General Partner deems appropriate. Upon reasonable request, such information 
shall be available for review by any Partner.

         (c)  A dissolution of the Partnership at the direction of the

                                        26
<PAGE>

         (e)  Entry of a decree of judicial dissolution under Colorado 
Statutes, Section 7-62-802.

         10.2 TERMINATION.  Upon dissolution, the Partnership shall be wound 
up and terminated unless, and in the event the dissolution is caused by the 
occurrence of an Event of Withdrawal with respect to the General Partner, 
within 90 days after the occurrence of such Event of Withdrawal, all Partners 
agree in writing to continue the business of the Partnership and to the 
admission of one or more additional General Partners if necessary or desired 
to continue the business of the Partnership. Expenses incurred in the 
reformation or attempted reformation of the Partnership shall be deemed 
expenses of the Partnership.

         10.3 DISTRIBUTION OF ASSETS.  Upon a dissolution of the Partnership, 
unless it is continued pursuant to Section 10.2, the General Partner (or, if 
there is no General Partner then remaining such other Person(s) designated by 
the Limited Partners) shall take full account of the Partnership assets and 
liabilities, shall liquidate the assets as promptly as is consistent with 
obtaining the fair value thereof, and shall apply and distribute the proceeds 
therefrom in the following order:

         (a)  To the payment of the expenses of liquidation and the debts and 
liabilities of the Partnership (other than any loans or advances that may 
have been made by the Partners to the Partnership);

         (b)  To the setting up of any reserves which the General Partner may 
deem necessary or appropriate for any anticipated obligations or 
contingencies of the Partnership or of the General Partner arising out of or 
in connection with the operation or business of the Partnership. Such 
reserves may be paid over by the General Partner to an escrow agent or 
trustee selected by the General Partner to be disbursed by such escrow agent 
or trustee in payment of any of the aforementioned obligations or 
contingencies and, if any balance remains at the expiration of such period 
as the General Partner shall deem advisable, to be distributed by such escrow 
agent or trustee in the manner hereinafter provided;

         (c)  To the repayment of any loans or advances which may have been 
made by any of the Partners to the Partnership, but if the amount available 
for such repayment shall be insufficient, then pro rata on account thereof; 
and

         (d)  To the Partners in accordance with their positive capital 
accounts and in accordance with Section 1.704-1(b)(2)(ii)(b)(2) of the 
Treasury Regulations.


                                        27
<PAGE>


Upon liquidation of any Partner's interest in the Partnership, liquidating 
distributions shall be made to such Partner in accordance with positive 
capital accounts and in accordance with Section 1.704-1(b)(2)(ii)(b)(2) of 
the Treasury Regulations. If at the time of liquidation the General Partner 
shall determine that an immediate sale of part or all of the Partnership 
assets would cause undue loss to the Partners, the General Partner may, in 
order to avoid loss, either defer liquidation and retain the assets or 
distribute the assets to the Partners in kind. In the event that the General 
Partner elects to distribute such assets in kind, the assets shall first be 
assigned a value and the unrealized appreciation or depreciation in value of 
the assets shall be allocated to the Partner's capital accounts, as if such 
assets had been sold and the gain or loss allocated in the manner described 
in Article IV, and such assets shall then be distributed to the Partners in 
accordance with their positive capital accounts.

         10.4 DEFICIT CAPITAL ACCOUNTS. The Limited Partners have no 
liability to the Partnership, to the other Partners, or to the creditors of 
the Partnership on account of any deficit balance in the Limited Partners' 
capital account.

         If a General Partner has a deficit balance in his capital account at 
the time of liquidation of the Partnership or the liquidation of his interest 
to the Partnership (after crediting allocations of income and debiting 
allocations of loss to its capital account), the General Partner must pay to 
the Partnership the amount of the deficit balance. This amount, upon 
liquidation of the Partnership, shall be paid to the creditors of the 
Partnership due such amounts or distributed to the other Partners in 
accordance with his positive capital account balance and in accordance with 
Section 1.704-1(b)(2)(ii)(b)(3) of the Treasury Regulations.

         This payment must be made in immediately available funds. This 
payment must be made no later than the end of the taxable year of the 
liquidation of its interest in the Partnership (or, if later, within ninety 
(90) days after the date of the liquidation).

                                   ARTICLE XI

                                 MISCELLANEOUS

         (a)  Each Limited Partner and General Partner shall become a 
signatory hereto by signing, directly or by an attorney-in-fact, this 
Agreement and such other instrument or instruments, and in such manner and at 
such time, as the General Partner shall


                                        28
<PAGE>


determine. By so signing, each Limited Partner and General Partner, as the 
case may be, shall be deemed to have adopted, and to have agreed to be bound 
by, all the provisions of this Agreement, as amended from time to time; 
provided, however, that no such counterpart shall be binding until it shall 
have been accepted by the General Partner.

         (b)  Except as provided in subsection (c) below, any amendment 
hereto shall be authorized and adopted upon the execution by all the Partners 
hereto.

         (c)  In making any amendments, there shall be prepared and filed by 
the General Partner for recording such documents and certificates as shall be 
required to be prepared and filed under the Act and under the laws of any 
other jurisdictions under which the Partnership is then formed or qualified.

         (d)  Any provision to the contrary herein notwithstanding, the 
General Partner may, without the consent of the Limited Partners, make any 
technical changes to the provisions of this Agreement to conform the 
allocations set forth in Article Four hereof to the requirements of 
regulations under Code Sections 704(b) and 704(c). Any amendment made by the 
General Partner in accordance with this Section 11.1(d), (i) shall be made 
pursuant to appropriate advice of counsel, and (ii) shall be deemed to have 
been made pursuant to the fiduciary obligations of the General Partner to the 
Partnership and the Limited Partners.

         11.2 NOTICES. Notices to the Partners shall be sent to the addresses 
set forth in Section 1.5. Any Partner may require notices to be sent to a 
different address by giving notice to the other Partners in accordance with 
this Section 11.2. All notices, requests, demands, consents and other 
communications required or permitted hereunder shall be by telecopy or in 
writing and shall be deemed to have been duly given and received when 
personally delivered to an officer of each party hereto, or transmitted by 
telecopier, confirmation received, to the telephone number specified below, 
or five business days after such notice is mailed, certified mail return 
receipt requested, first-class postage prepaid, or the next day after such 
notice is sent by commercial courier.

         11.3 WAIVER OF PARTITION. No Partner or successor in interest to any 
Partner may have any property of the Partnership partitioned, or, except as 
provided by applicable law, file a complaint or institute any proceeding at 
law or in equity to have the property partitioned, and each Partner for itself,
its successors, representatives, and assigns, hereby waives any right to proceed
under any applicable law or otherwise to partition any Partnership property. Any
creditor of a Partner shall have


                                        29

<PAGE>

recourse only against such Partner's interest in the Partnership, but such 
creditor shall not have any recourse against the property of the Partnership.

agreement among the parties and supersedes any prior agreement or 
understanding among them representing the subject matter of this Agreement.

         11.5 HEADINGS. All article and section headings in this Agreement 
are for convenience of reference only and shall not control or alter the 
meaning of this Agreement as set forth in this text.

         11.6 CERTAIN PROVISIONS. If the operation of any provision of this 
Agreement would contravene the provisions of the Revised Uniform Limited 
Partnership Act as in effect in the State of Colorado, or would result in the 
imposition of general liability on any Limited Partner, such provision shall 
be void and ineffectual.

         11.7 SEPARABILITY. Each provision of this Agreement shall be 
considered separable and if, for any reason, any provision or provisions 
hereof are determined to be invalid and contrary to existing or future law, 
such invalidity shall not impair the operation of or affect those portions of 
this Agreement that are valid.

         11.8 PRONOUNS AND PLURALS. All pronouns and any variations thereof 
shall be deemed to refer to the masculine, feminine, neuter, singular, or 
plural as the identity of the person or persons may require.

inure to the benefit of, the parties hereto, their successors, heirs, 
legatees, devisees, assigns, legal representatives, executors and 
administrators, except as otherwise provided herein.

         11.10 COUNTERPARTS. This Agreement may be executed in sereval 
counterparts, and all so executed shall constitute one agreement, binding on 
all the parties hereto, even though all parties are not signatory to the 
original or the same counterpart. Any counterpart of either this Agreement or 
the Certificate, which has attached to it separate signature pages, which 
altogether contain the signatures of all Partners, shall for all purposes be 
deemed a full executed instrument. Each party to the Agreement agrees that it

         11.11 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND 
CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF COLORADO 
WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS. EACH OF THE PARTIES HERETO 
AGREE TO SUBMIT TO THE JURISDICTION OF ANY FEDERAL COURT IN THE STATE OF 
COLORADO, AND TO VENUE IN THE CITY AND COUNTY OF DENVER FOR ALL MATTERS 
CONCERNING THE INTERPRETATION, CONSTRUCTION OR ENFORCEMENT OF THIS AGREEMENT 
OR FOR ANY OTHER MATTERS CONCERNING OR ARISING OUT OF THIS AGREEMENT.

         11.12 NO BENEFIT TO THIRD PARTIES. The provisions of this Agreement 
shall not be construed for the benefit of or enforceable by a person not a 
party hereto, including but not limited to any creditor of any Partner or any 
of their affiliates.

         11.13 COMPLIANCE WITH SECURITIES LAWS. No Partnership interest has 
been or may be registered under the Securities Act of 1933, as amended, or any 
state securities law, without the consent of the General Partner. A Partner 
may not transfer all or any part of his interest, except upon compliance with 
the applicable federal and state securities laws. The General Partner shall 
have no obligation to register any Partner's interest under the Securities 
Act of 1933, as amended, or any state securities law, or to make any 
exemption therefrom available to any Partner.

         11.14 LIMITATION ON USE IN CASE OF DISTRIBUTION OF SOFTWARE. To the 
extent that any of the Partners receive rights to any of the assets of the 
Partnership by distribution in liquidation or otherwise, such Partners agree 
that they will be subject to and shall comply with the limitations on the use 
of Partnership software and the confidentiality provisions contained herein, 
subject however to the terms of any other agreement the Partners may enter 
into with the Partnership or among themselves which shall govern. The terms of 
this Section 11.14 shall survive any termination of this Agreement. Each 
Partner or Affiliate of the Partner shall have a worldwide, personal, 
nontransferable, and nonexclusive right to reproduce, modify, translate and 
use the software. The software shall be used only for the processing of the 
brokerage business of the Partner or an Affiliate of the Partner, including, 
but not limited to, correspondent business on either a fully disclosed or 
omnibus basis, and shall not be used in the operation of a service bureau or 
sold or otherwise made available for use by a non-Affiliated entity. The 
software and any modifications, changes, enhancements, conversions, upgrades 
or additions made to the software, made by the Partnership or a third party 
on the Partnership's behalf, shall be the sole and exclusive property of the 
Partnership, including all applicable rights to patents, copyrights, 
trademarks and trade secrets inherent therein and appurtenant thereto. Any 
modifications, changes, enhancements, conversions, upgrades or additions 
made to the software by a Partner or an Affiliate of the Partner or a third 
party on the 

                                 31

<PAGE>

Partner's or an Affiliate's behalf ("Permitted Modifications") shall be the 
sole and exclusive property of such Partner or Affiliate, including all 
applicable rights to patents, copyrights, trademarks and trade secrets 
inherent therein and appurtenant thereto and the Partner or its Affiliate 
shall have the right to use the Permitted Modifications without charge 
pursuant to the terms of the License Agreement. Notwithstanding the above, 
nothing herein shall prevent the making of modifications, changes, 
enhancements, upgrades or additions or developing any new software products 
by a Partner which produce the same or similar results, data, reports or 
information produced by the Permitted Modifications. Each Partner shall not 
sell, transfer, publish, disclose, display or otherwise make available to 
others (except for Affiliates) any source code, object code, documentation or 
other material relating to the software. Each Partner shall obtain agreements 
from its employees and the Affiliates' employees maintaining confidentiality 
of, and prohibiting unauthorized use of disclosure of, the source code or 
object code of the software or of any portion of the software, or any of the 
algorithms or logic contained therein. Without limitation of the foregoing, a 
Partner shall advise the other Partners immediately in the event that the 
Partner learns or has reason to believe that any person who has had access to 
the software, or any portion thereof, has violated or intends to violate the 
terms of this Section; and the Partner will (at such Partner's own expense), 
cooperate with the other Partners in seeking injunctive or other equitable 
relief against such Person.

         11.15 CONFIDENTIALITY. Each Partner acknowledges that the software 
contains proprietary trade secrets and hereby agrees to maintain the 
confidentiality of the software in a manner using at least as great a degree 
of care as the manner used to maintain the confidentiality of the Partner's 
own most confidential information. Each Partner acknowledges that the 
disclosure of any aspect of the software, of any of the confidential 
information referred to herein or any information which, at law or equity, 
ought to remain confidential within the Partner and any of its Affiliates, 
will give rise to irreparable injury to the Partnership or the Partners as a 
group inadequately compensable in damages. Accordingly, the Partnership or 
any Partner may seek or obtain injunctive relief against the breach or 
threatened breach of any of the foregoing undertakings, in addition to any 
other legal remedies which may be available, and each Partner hereby consents 
to the obtaining of such injunctive relief. The terms of this Section 11.15 
shall survive any termination of this Agreement.

                         LIMITED LIABILITY COMPANY AGREEMENT
                                          OF

    This AMENDED AND RESTATED LIMITED LIABILITY COMPANY AGREEMENT of 
Roundtable Partners, L.L.C. (the "Agreement") is made and entered into as of 
March ___, 1995 by and among the Members.

    FOR AND IN CONSIDERATION OF and reliance upon the mutual covenants, 
rights and obligations set forth herein, the benefits to be derived therefrom 
and the relationship of trust, confidence, fair dealing and utmost good faith 
created hereby, and other good and valuable consideration, the receipt and 
the sufficiency of which each Member acknowledges and confesses, the Members 
agree that the Agreement shall be the limited liability company agreement of 
the Company and shall replace in its entirety the limited liability company 
agreement, dated October 1, 1994, entered into by Walter Raquet and Kenneth 
Pasternak (a copy of which is attached as Exhibit 1 hereto), which shall be 
of no further force and effect, and further agree as follows:

                                      ARTICLE I
                                     DEFINITIONS
                                           
    1.1  DEFINITIONS.   As used herein, the following terms shall have the 
respective meanings set forth below:

              ACT - the Delaware Limited Liability Company Act and any 
successor statute, as amended from time to time.

         ADJUSTED CAPITAL ACCOUNT - the Capital Account maintained for each 
Member as of the end of each fiscal year of the Company (a) increased by (i) 
the 

<PAGE>
                                       -2-

amount of any unpaid capital contributions, if any, unconditionally agreed to 
be contributed by such Member under Article IV of this Agreement, (ii) an 
amount equal to the sum of such Member's allocable share of the Company's 
Minimum Gain attributable to Company Nonrecourse Liabilities and such 
Member's allocable share of the Company's Minimum Gain attributable to Member 
Nonrecourse Debt, in each case as computed on the last day of such fiscal 
year in accordance with applicable Treasury Regulations, and (iii) the amount 
of Company liabilities allocable to such Member under Section 752 of the Code 
with respect to which such Member bears the Economic Risk of Loss to the 
extent such liabilities do not constitute "Member Nonrecourse Debt" and (b) 
reduced by all reasonably expected adjustments, allocations and distributions 
described in Treas. Reg. Section 1.704-1(b) (2) (ii) (d) (4), (5) and (6).  
For purposes of this definition of "Adjusted Capital Account," any recourse 
debt for which no Member bears the Economic Risk of Loss shall be treated as 
a Company Nonrecourse Liability.

         ADJUSTED PROPERTY - means any property, the Carrying Value of which 
has been adjusted pursuant to Section 4.3(d) (i) or 4.3 (d) (ii).  Once an 
Adjusted Property is deemed distributed by, and recontributed to, the Company 
for federal income tax purposes upon a termination thereof pursuant to 
Section 708 of the Code, such property shall thereafter constitute 
Contributed Property until the Carrying Value of such property is thereafter 
adjusted pursuant to Section 4.3(d) (i) or 4.3 (d) (ii).

         ADVISORY COMMITTEE - as defined in Section 6.2(a).

         AFFILIATE - (a) with respect to any Person who is a natural person, 
(i) each Entity that such Person controls and (ii) each member of such 
Person's immediate family and (b) with respect to any Entity, (i) each Entity 
that such Entity controls, (ii) each Person that controls such Entity and 
(iii) each Entity that is under common control with such Entity.  For the 
purposes of the preceding sentence, the term "control" shall mean the 
possession, directly or indirectly, through one or more intermediaries, of 
the power or authority, through ownership of voting securities, by Contract 
or otherwise, to direct the management, activities or policies of the Entity. 
 With respect to the Company, an Affiliate thereof shall be deemed to include 
an Entity that is controlled by the Company.

         AGREED VALUE - of any Contributed Property means the fair market 
value of such property or other consideration at the time of contribution,
as determined by the Advisory Committee using such reasonable method of 
valuation as it may adopt; PROVIDED, however, that the Agreed Value of any 
property deemed contributed to the Company for federal income tax purposes 
upon termination and reconstitution thereof pursuant to Section 708 of the 
Code shall be determined in accordance with Section 4.3(c).  Subject to 
Section 4.3(c), the Advisory Committee shall, in its sole discretion, use 
such method as it deems reasonable and appropriate to allocate the aggregate 
Agreed Value of Contributed Properties contributed to the Company in a single 
or integrated transaction among each separate property on a basis 
proportional to the fair market value of each Contributed Property.

         BANKRUPT MEMBER - any Member (a) that (i) makes an assignment for 
the benefit of creditors, (ii) files a voluntary petition in bankruptcy, 
(iii) is adjudged bankrupt or insolvent or has entered against the Member an 
order for relief in any bankruptcy or insolvency proceeding, (iv) files a 
petition or answer seeking for the Member a reorganization, arrangement, 
composition, readjustment, liquidation, dissolution or similar relief under 
any statute, law or regulation, (v) files an answer or other pleading 
admitting or failing to contest the material allegations of a petition filed 
against the Member in a proceeding of the type described in subclauses (i) 
through (iv) of this clause (a), or (vi) seeks, consents to, or acquiesces in 
the appointment of a trustee, receiver or liquidator of the Member or of all 
or any substantial part of the Member's properties or (b) against which a 
proceeding seeking reorganization, arrangement, composition, readjustment, 
liquidation, dissolution or similar relief under any statute, law or 
regulation has been commenced and 120 days have expired without dismissal or 
stay thereof or with respect to which, without the Member's consent or 
acquiescence, a trustee, receiver or liquidator of the Member or of all or 
any substantial part of the Member's properties has been appointed and 90 
days have expired without the decree or order making such appointment having 
been vacated or stayed, or 90 days have expired after the date of expiration 
of a stay, if the appointment has not previously been vacated.

Disparities in all of its Contributed Property and Adjusted Property will be 
reflected by the difference between such Member's Capital Account balance as

Member's Capital Account computed as if it had been maintained strictly in 
accordance with federal income tax accounting principles.

tax

Membership Interest or any portion thereof).

    3.4  ADDITIONAL INTERESTS.  Additional Membership Interests may be

    4.1  CAPITAL CONTRIBUTIONS.

         (a)  Effective as of the Effective Date, each of the Members (other 
than Trimark Securities) has contributed the amount of cash set forth next to 
such Member's name on Schedule A hereto to the Company as a Capital 
Contribution and Trimark Securities shall be treated as having sold, and not 
contributed as a Capital Contribution, the Trimark Interest to the Company.

         (b)  No Member shall have any obligation to make any capital 
contribution other than the capital contribution referred to in section 
4.1(a), except that each Management Investor shall, upon the admission of any 
additional Members, be required to contribute capital in exchange for Common 
Units such that the Common Interest of such Management Investor immediately 
after the admission of such new Members is not less than the Common Interest 
of such Management Investor immediately before such admission; provided that 
this obligation of each Management Investor shall expire at such time as such 
Management Investor shall, in the aggregate, have made capital contributions 
to the Company of $3 million.

    4.2  RETURN OF CONTRIBUTIONS.  A Member is not entitled (except as 
otherwise expressly provided by other provisions of this Agreement) to the 
return of any part of its Capital Contributions or to be paid interest in 
respect of either its Capital Account or its Capital Contributions.  An 
unrepaid Capital Contribution is not a liability of the Company or of the 
other Members. A Member is not required to contribute or to lend any cash or 
property to the Company to enable the Company to return any other Members' 
Capital Contributions.

    4.3  CAPITAL ACCOUNTS.  

         (a)  The Company shall maintain for each Member owning a Membership 
Interest a single, separate Capital Account with respect to such Membership 
Interest in accordance with the rules of Treasury Regulation Section 
1.704-1(b)(2)(iv).  Such Capital Account shall be increased by (i) the amount 
of cash and the Net Agreed Value of all property transferred to the Company 
as Capital Contributions with respect to such Membership Interest pursuant to 
this Agreement and (ii) all items of Company income and gain (including, 
without limitation, income and gain exempt from tax) computed in accordance 
with Section 4.3(b) and allocated to such Membership Interest pursuant to 
Section 5.1, and decreased by (x) the amount of cash and the Net Agreed Value 
of all actual and deemed distributions of cash or property made with respect 
to such Membership Interest pursuant to this Agreement and (y) all items of 
Company deduction and loss computed in accordance with Section 4.3(b) and 
allocated to such Membership Interest pursuant to Section 5.1.

         (b)  For purposes of computing the amount of any item of income, 
gain, loss or deduction to be reflected in the Members' Capital Accounts, the 
determination, recognition and classification of any such item shall be the 
same as its determination, recognition and classification for federal income 
tax purposes (including, without limitation, any method of depreciation, cost 
recovery or amortization used for that purpose), provided, that:

          (i) Except as otherwise provided in Treasury Regulation 
      Section 1.704-1(b)(2)(iv)(m), the computation of all items of income, 
      gain, loss and deduction shall be made without regard to any election 
      under Section 754 of the Code which may be made by the Company and, as 
      to those items described in Section 705(a)(1)(B) or 705(a)(2)(B) of the 
      Code, without regard to the fact that such items are not includable in 
      gross income or are neither currently deductible nor capitalized for 
      federal income tax purposes.

         (ii) Any income, gain or loss attributable to the taxable 
      Disposition of any Company property shall be determined as if the 
      adjusted basis of such property as of such date of Disposition were 
      equal in amount to the Company's Carrying Value with respect to such 
      property as of such date.

<PAGE>
                                       -23-

        (iii) In accordance with the requirements of Section 704(b) 
      of the Code, any deductions for depreciation, cost recovery or 
      amortization attributable to any Contributed Property shall be 
      determined as if the adjusted tax basis of such property on the date it 
      was acquired by the Company were equal to the Agreed Value of such 
      property.  Upon an adjustment pursuant to Section 4.3(d) to the 
      Carrying Value of any Company property subject to depreciation, cost 
      recovery or amortization, any further deductions for such depreciation, 
      cost recovery or amortization attributable to such property shall be 
      determined (A) as if the adjusted tax basis of such property were equal 
      to the Carrying Value of such property immediately following such 
      adjustment and (B) using a rate of depreciation, cost recovery or 
      amortization derived from the same method and useful life (or, if 
      applicable, the remaining useful life) as if applied for federal income 
      tax purposes; provided, however, that if the asset has a zero adjusted 
      basis for federal income tax purposes, depreciation, cost recovery or 
      amortization deductions shall be determined using any reasonable method 
      that the Advisory Committee may adopt.

         (c)  A transferee of a Membership Interest shall succeed to a pro rata
portion of the Capital Account of the transferor relating to the Membership
Interest so transferred; provided, however, that, if the transfer causes a
termination of the Company under Section 708(b)(1)(B) of the Code, the Company's
properties shall be deemed to have been distributed in liquidation of the
Company to the Members (including any transferee of a Membership Interest that
is a party to the transfer causing such termination) pursuant to Section 12.2
and recontributed by such Members in reconstitution of the Company.  Any such
deemed distribution shall be treated as an actual distribution for purposes of
this Section 4.3.  In such event, the Carrying Values of the Company properties
shall be adjusted immediately prior to such deemed distribution pursuant to
Section 4.3(d)(ii) and such Carrying Values shall then constitute the Agreed
Values of such properties upon such deemed contribution to the reconstituted
Company.  The Capital Accounts of such reconstituted Company shall be maintained
in accordance with the principles of this Section 4.3.

          (d) (i) Consistent with the provisions of Treasury Regulation 
      Section 1.704-1(b)(2)(iv)(f), on an issuance of additional Common Units 
      for cash or Contributed Property, the Capital Accounts of all Members 
      and the Carrying Value

<PAGE>
                                       -24-

      of each Company property immediately prior to such issuance shall be 
      adjusted upward or downward to reflect any Unrealized Gain or 
      Unrealized Loss attributable to such Company property, as if such 
      Unrealized Gain or Unrealized Loss had been recognized on an actual 
      sale of each such property immediately prior to such issuance and had 
      been allocated to the Members at such time pursuant to Section 5.1.  In 
      determining such Unrealized Gain or Unrealized Loss, the aggregate cash 
      amount and fair market value of all Company assets (including, without 
      limitation, cash or cash equivalents) immediately prior to the issuance 
      of additional Membership Interests shall be determined by the Advisory 
      Committee using such reasonable method of valuation as it may adopt; 
      provided, however, the Advisory Committee, in arriving at such 
      valuation, must take fully into account the fair market value of the 
      Membership Interests of all Members at such time.  The Advisory 
      Committee shall allocate such aggregate value among the assets of the 
      Company (in such manner as it determines in its sole discretion to be 
      reasonable) to arrive at a fair market value for individual properties.

              (ii) In accordance with Treasury Regulation Section 
      1.704-1(b)(2)(iv)(f), immediately prior to any actual or deemed 
      distribution to a Member of any Company property (other than (A) a 
      distribution of cash that is not in redemption or retirement of any 
      portion of a  Membership Interest or (B) a distribution that is in 
      redemption of a Preferred A Interest or a Preferred B Interest), the 
      Capital Accounts of all Members and the Carrying Value of such Company 
      property shall be adjusted upward or downward to reflect any Unrealized 
      Gain or Unrealized Loss attributable to such Company property, as if 
      such Unrealized Gain or Unrealized Loss had been recognized in a sale 
      of such property immediately prior to such distribution for an amount 
      equal to its fair market value, and had been allocated to the Members, 
      at such time, pursuant to Section 5.1.  In determining such Unrealized 
      Gain or Unrealized Loss the aggregate cash amount and fair market value 
      of all Company assets (including, without limitation, cash or cash 
      equivalents) immediately prior to a distribution shall (A) in the case 
      of a deemed distribution occurring as a result of a termination of the 
      Company pursuant to Section 708 of the Code, be determined and 
      allocated in the same manner as that provided in Section 4.3(d)(i) or 
      (B) in the case of a liquidating distribution pursuant to Section 12.2 
      be determined and allocated by the liquidator using such reasonable 
      method of valuation as it may adopt.

         (e)  Capital Accounts shall be adjusted, in a manner consistent with
this Section 4.3, to reflect any adjustments in items of the Company's income,
gain, loss or deduction that result from amended returns filed by the Company or
pursuant to an agreement by the Company with the Internal Revenue Service or a
final court decision.

    4.4  ADVANCES BY MEMBERS.  Except as approved by the Advisory Committee, or
provided for specifically herein, no Member may advance any money or other
property to, or contribute any money or property to, the Company.

                            ALLOCATIONS AND DISTRIBUTIONS
                                           
    5.1  ALLOCATIONS FOR CAPITAL ACCOUNT PURPOSES.  For purposes of maintaining
the Capital Accounts and in determining the rights of the Members among
themselves, the Company's items of income, gain, loss and deduction (computed in
accordance with Section 4.3(b)) shall be allocated among the Members in each
taxable year (or portion thereof) as provided herein below.

         (a)  After giving effect to the special allocations set forth in
Section 5.1(c), Net Income for each taxable period and all items of income and
gain taken into account in computing Net Income for such taxable period shall be
allocated to the Members in the following order and priority:  

              (i)  first, to each Preferred A Holder in an amount equal to 
      the Preferred A Holder's Untaxed Preference Amount;

         (ii) second, to each Preferred B Holder in an amount equal to the 
      Preferred B Holder's Untaxed Preference Amount;

         (iii)     third, to each Member in an amount equal to the excess, if 
      any, of Net Losses allocated to such Member under Section 5.1(b)(v) 
      over Net Income previously allocated to such Member under this Section 
      5.1.(a)(iii).

<PAGE>
                                       -26-

         (iv) fourth, to each Member in an amount equal to the excess of Net 
      Losses allocated to such Member under Section 5.1(b)(iv) over Net 
      Income previously allocated to such Member under this Section 
      5.1(a)(iv).  For purposes of this Section 5.1(a)(iv), Net Income shall 
      be allocated among the Members in a manner that "unwinds" the 
      allocation of Net Losses set forth in Section 5.1(b)(iv), I.E., taking 
      into account allocations made under the second sentence of Section 
      5.1(b)(iv) before taking into account allocations made under the first 
      sentence of Section 5.1(b)(iv).

         (v)  fifth, in accordance with their respective Trimark Order Flow 
      Percentages, in an aggregate amount equal to the result obtained by 
      multiplying (A) 50 percent of the Net Income which was not allocated 
      pursuant to Section 5.1(a)(i), (ii) (iii) and (iv) by (B) the Trimark 
      Income Percentage for such taxable period.

         (vi) sixth, in accordance with their respective Knight Order Flow 
      Percentages, in an aggregate amount equal to the excess of 
      (A) 50 percent of the Net Income which was not allocated pursuant to 
      Sections 5.1(a)(i), (ii), (iii) and (iv) over (B) the Net Income 
      allocated pursuant to Section 5.1(a)(v).

         (vii) seventh, in accordance with their respective Common Interests.

         (b)  After giving effect to the special allocations set forth in
Section 5.1(a), Net Loss for each taxable period and all items of loss and
deduction taken into account in computing Net Loss for such taxable period shall
be allocated to the Members in the following order and priority:

          (i)  first, with respect to any Preferred A Units converted 
      pursuant to Section 11.1, to each Preferred A Holder to the extent of 
      the excess, if any, of (A) allocations made with respect to any such 
      converted Preferred A Units pursuant to Section 5.1(a)(i) over (B) the sum
      of (1) distributions made with respect to any such converted Preferred A 
      Units pursuant to 

<PAGE>
                                       -27-

      Section 5.3(a)(ii) and (2) any Net Loss previously allocated to such 
      Preferred A Holder pursuant to this Section 5.1(b)(i).

         (ii) [intentionally omitted].

         (iii) third, to all the Members in accordance with their respective 
      Common Interests, but only to the extent such amount when so allocated 
      would not result in, or cause an increase in, a deficit balance in any 
      Member's Adjusted Capital Account.  

         (iv) fourth, to the Members that (after the application of Sections 
      5.1(b)(i)-(iii)) do not have an Adjusted Capital Account with a deficit 
      balance in accordance with their respective Common Interests; but only 
      to the extent such amount when so allocated would not result in, or 
      cause an increase in, a deficit balance in any Member's Adjusted 
      Capital Account.  This Section 5.1(b)(iv) shall be applied, MUTATIS 
      MUTANDIS, until the allocation of Net Losses would cause each of the 
      Members to have a deficit balance in such member's Adjusted Capital 
      Account.

         (v)  fifth, to each Member in proportion to its respective Common 
      Interest.

         (c)  Notwithstanding any other provision of this Section 5.1, the
following special allocations shall be made for each taxable period:
          
          (i)  MINIMUM GAIN CHARGEBACK.  If, at any time during any Company 
      taxable period, there is a net decrease in Minimum Gain attributable to 
      Company Nonrecourse Liabilities, then to the extent of such decrease 
      items of Company income and gain for such period (and, if necessary, 
      subsequent periods) shall be specially allocated as quickly as possible 
      to each Member having a share of the Minimum Gain attributable to 
      Company Nonrecourse Liabilities, in proportion to, and to the extent 
      of, the portion of such Member's share of the net decrease during such 
      period in Minimum Gain attributable to Company Nonrecourse Liabilities. 
       The items to be so allocated shall be determined in accordance with 
      Treasury

<PAGE>
                                       -28-
 
      Regulations Sections 1.704-2(f)(6) and 1.704-2(j)(2).  This Section 
      5.1(c)(i) is intended to comply with the minimum gain chargeback 
      requirement in Treasury Regulations Section 1.704-2(f) and shall be 
      interpreted consistently therewith.

         (ii) MEMBER MINIMUM GAIN CHARGEBACK.  If, at any time during any 
      Company taxable period, there is a net decrease in the Minimum Gain 
      attributable to Member Nonrecourse Debt, then to the extent of such 
      decrease items of Company income and gain for such period (and, if 
      necessary, subsequent periods) shall be specially allocated as quickly 
      as possible to each Member having a share of the Minimum Gain 
      attributable to Member Nonrecourse Debt in proportion to, and to the 
      extent of, the portion of such Member's share of the net decrease 
      during such period in Minimum Gain attributable to Member Nonrecourse 
      Debt.  The items to be so allocated shall be determined in accordance 
      with Treasury Regulations Sections 1.704-2(i)(4) and 1.704-2(j)(2).  
      This Section 5.1(c)(ii) is intended to comply with the partner minimum 
      gain chargeback requirement in the foregoing section of the Treasury 
      Regulations and shall be interpreted consistently therewith.
         
        (iii) QUALIFIED INCOME OFFSET.  If, at any time during any 
      Company taxable period any Member unexpectedly receives any 
      adjustments, allocations or distributions described in Treasury 
      Regulations Section 1.704-l(b)(2)(ii)(d)(4), (5) or (6), and if such 
      adjustment, allocation or distribution would result in or increase a 
      deficit balance in the Adjusted Capital Account of such Member as of 
      the end of a Company taxable year, then items of Company income and 
      gain shall be specially allocated to such Member in an amount and 
      manner sufficient to eliminate (to the extent required by the foregoing 
      Treasury Regulations) such deficit as quickly as possible, provided 
      that an allocation pursuant to this Section 5.1(c)(iii) shall be made 
      only if and to the extent that such Member would have a deficit balance 
      in its Adjusted Capital Account after all other allocations provided 
      for in this Article 5 have been tentatively made as if this Section 
      5.1(c)(iii) were not in this Agreement.

                                       -29-

         (iv) MEMBER NONRECOURSE DEDUCTIONS.  The Member Nonrecourse 
      Deductions for any taxable period shall be specially allocated in 
      accordance with Treasury Regulations Section 1.704-(2)(i)(1) among the 
      Members bearing the Economic Risk of Loss with respect to the Member 
      Nonrecourse Debt to which such Member Nonrecourse Deductions are 
      attributable.
    
          (v)  CODE SECTION 754 ADJUSTMENTS.  To the extent that an 
      adjustment to the adjusted tax basis of any asset of the Company under 
      Sections 734(b) or 743(b) of the Code is required to be taken into 
      account in determining Capital Accounts pursuant to Treasury 
      Regulations Section 1.704-1(b)(2)(iv)(m), the amount of such adjustment 
      to the Capital Accounts shall be treated as an item of gain (if the 
      adjustment increases the basis of the asset) or loss (if the adjustment 
      decreases such basis), and such gain or loss shall be specially 
      allocated to the Members in a manner consistent with the manner in 
      which their Capital Accounts are required to be adjusted pursuant to 
      such Treasury Regulations.
    
         (vi) CURATIVE ALLOCATIONS.  Notwithstanding any other provisions of 
      this Section 5.1, the Required Allocations, if any, made pursuant to 
      this Section 5.1(c) shall be taken into account in allocating other Net 
      Income, Net Loss and items of Company income, gain, loss and deduction 
      for the Company taxable year in which such Required Allocation occurs 
      and each subsequent Company taxable year among the Members so that, to 
      the extent possible, the net amount of income, gain, loss, deduction 
      and other items allocated to each Member shall be equal to the net 
      amount that would have been allocated to each such Member if the 
      Required Allocations had not been made.  Notwithstanding the preceding 
      sentence, (i) allocations of Member Nonrecourse Deductions shall not be 
      taken into account hereunder except to the extent that there has been a 
      net decrease in Minimum Gain attributable to Member Nonrecourse Debt 
      and (ii) allocations of Company Nonrecourse Deductions shall not be 
      taken into account hereunder except to the extent there has been a net 
      decrease in Minimum Gain attributable to Company Nonrecourse 
      Liabilities.

                                       -30-

        (vii) EXCESS NONRECOURSE LIABILITIES.  Solely for purposes of 
      determining each Member's proportionate share of the "excess 
      nonrecourse liabilities" of the Company within the meaning of Treasury 
      Regulation Section 1.752-3(a)(3), each Member's interest in the Net 
      Income of the Membership shall be its Common Interest, as adjusted from 
      time to time.

       (viii) ALLOCATIONS GREATER THAN 20 PERCENT.  No allocation of Net 
      Income or Net Loss shall be made to any Member if such allocation would 
      cause such Member to have allocated to it an amount in excess, in any 
      taxable year, of greater than 20 percent of the Company's Net Income or 
      Net Loss for such year; provided any Net Income or Net Loss not 
      allocated pursuant to this Section 5.1(c)(viii) shall be allocated 
      among the other Members in accordance with their respective Common 
      Interests (which allocation shall again be subject to the limitation 
      contained in this Section 5.1(c)(viii)).

    5.2  ALLOCATIONS FOR TAX PURPOSES

         (a)  Except as otherwise provided herein, for federal income tax
purposes, (i) each item of income, gain, loss and deduction shall be allocated
among the Members in the same manner as its correlative items of "book" income,
gain, loss or deduction is allocated pursuant to Section 5.1, and (ii) each tax
credit shall be allocated to the Members in the same manner as the receipt or
expenditure giving rise to such credit is allocated pursuant to Section 5.1.

         (b)  In an attempt to eliminate Book-Tax Disparities attributable to a
Contributed Property or Adjusted Property, items of income, gain, loss,
depreciation, amortization and cost recovery deductions shall be allocated for
federal income tax purposes among the Members as follows:

              (i)  (A)  In the case of a Contributed Property, such items 
      attributable thereto shall be allocated among the Members in the manner 
      provided under Section 704(c) of the Code that takes into account the 
      variation between the Agreed Value of such property and its adjusted 
      tax basis at the time of contribution; and (B) any item of Residual 
      Gain or

<PAGE>
                                       -31-

      Residual Loss attributable to a Contributed Property shall be allocated 
      among the Members in the same manner as its correlative item of "book" 
      gain or loss is allocated pursuant to Section 5.1.

         (ii) (A)  In the case of an Adjusted Property, such items shall (1) 
      first, be allocated among the Members in a manner consistent with the 
      principles of Section 704(c) of the Code to take into account the 
      Unrealized Gain or Unrealized Loss attributable to such property and 
      the allocations thereof pursuant to Section 4.3(d)(i) or (ii), and (2) 
      second, in the event such property was originally a Contributed 
      Property, be allocated among the Members in a manner consistent with 
      Section 5.2(b)(i)(A); and (B) any item of Residual Gain or Residual 
      Loss attributable to an Adjusted Property shall be allocated among the 
      Members in the same manner as its correlative item of "book" gain or 
      loss is allocated pursuant to Section 5.1.

         (iii) To correct distortions created by the "Ceiling rule" of 
      Treasury Regulation Section 1.704-3(b)(1), to the extent permitted or 
      required by Treasury Regulations, the Company may make curative 
      allocations of Company tax items (other than those with respect to 
      property which is subject to the allocations contained in clauses (i) 
      and (ii) above) so that allocations of tax items be made to effect the 
      purposes of Code Sections 704(b) and 704(c) by allocating the tax 
      consequences of precontribution gain or loss to a contributing Member.

         (c)  Any gain allocated to the Members upon the sale or other taxable
Disposition of any Company asset shall, to the extent possible, after taking
into account other required allocations of gain pursuant to this Section 5.2, be
characterized as Recapture Income in the same proportions and to the same extent
as such Members (or their predecessors in interest) have been allocated any
deductions directly or indirectly giving rise to the treatment of such gains as
Recapture Income.

         (d)  All items of income, gain, loss, deduction and credit recognized
by the Company for federal income tax purposes and allocated to the Members in
accordance with the provisions hereof shall be determined without regard to any
election under Section 754 of the Code which may be made by the Company;
provided, however, that

<PAGE>
                                       -32-

such allocations, once made, shall be adjusted as necessary or appropriate to 
take into account those adjustments permitted or required by Sections 734 and 
743 of the Code.

         (e)  For federal income tax purposes, the Trimark Interest shall be
treated as having been sold, and not contributed, to the Company pursuant to
Section 707 of the Code.

                                       -33-

    5.3  DISTRIBUTIONS.

         (a)  The Company shall distribute cash or other property to the
Members as set forth below:

        (iii) third, no less than three days prior to April 15 of each 
      year, the Company shall distribute to the Members (the "April 
      Distribution") (pro rata, in proportion to the amount of Net Income 
      allocated to the Members pursuant to Sections 5.1(a)(iii) through (vii) 
      with respect to the preceding taxable year), an amount equal to 50 
      percent of the excess of (A) the Net Income of the Company for the 
      preceding taxable year over (B) the amounts allocated pursuant to 
      Sections 5.1(a)(i) and (ii) with respect to such preceding taxable 
      year, plus if the Company's Net Income for any year is increased above 
      the amount used to compute the April Distribution as a result of an 
      adjustment deemed necessary by the Company or as the result of a tax 
      audit, the Company shall make an additional distribution in such amount 
      as the Advisory Committee shall determine is appropriate, in its good 
      faith discretion, taking into account the respective additional 
      federal, state and local tax liability of the Members as a result of 
      such increase and any related penalties and interest;

         (iv) fourth, on April 15 of each Company Year, the Company shall 
      distribute to each Preferred A Holder a pro rata portion of fifty 
      percent (or such higher percentage as may be determined by the Advisory 
      Committee) of the excess of the Net Income for the immediately 
      preceding Company taxable year over the sum of (a) the aggregate amount 
      of the distributions with respect to such year required by Section 
      5.3(a)(iii) plus (b) fifty percent

<PAGE>
                                       -34-

      of the aggregate amount of the distributions with respect to such year 
      required by Sections 5.3(a)(i) and (ii); provided, that any 
      distributions made pursuant to this Section 5.3(a)(iv) shall be in 
      redemption of that number of Preferred A Units equal to one-tenth of 
      the dollar amount of the distribution made pursuant to this Section 
      5.3(a)(iv); provided further, that no distribution shall be made under 
      this Section 5.3(a)(iv) in excess of the aggregate for all Preferred A 
      Holders of the Preferred A Holder's Preferred Capital Amounts 
      immediately before such distribution;

         (v) fifth, on April 15 of each Company Year occurring after the date 
      on which all of the Preferred A Units have been either redeemed 
      pursuant to Section 5.3(a)(iv) or converted pursuant to Section 11.1, 
      the Company shall distribute to each Preferred B Holder a pro rata 
      portion of fifty percent of the excess of Net Income for such taxable 
      year over the sum of (a) the aggregate amount of the distributions with 
      respect to such taxable year required by Section 5.3(a)(iii) plus (b) 
      fifty percent of the aggregate amount of the distributions with respect 
      to such year required by Section 5.3(a)(i) and (ii); provided, that any 
      distributions made pursuant to this Section 5.3(a)(v) shall be in 
      redemption of that number of Preferred B Units equal to one-tenth of 
      the dollar amount of the distribution made pursuant to this Section 
      5.3(a)(v); provided further, that no distribution shall be made under 
      this Section 5.3(a)(v) in excess of the Preferred B Holder's Preferred 
      Capital Amount immediately before such distribution; and

         (vi) sixth, the Company shall periodically make distributions to the 
      Members in accordance with their respective Capital Accounts (after 
      reduction for the amount of any such Capital Account attributable to 
      the acquisition of Preferred A Units or Preferred B Units and any 
      allocations and distributions made as a result of the ownership of 
      Preferred A Units or Preferred B Units), with the timing and aggregate 
      amount of each distribution, if any, to be determined by the Advisory 
      Committee.

         (b)  Notwithstanding the foregoing:

<PAGE>
                                       -35-

              (i)  the Company may make distributions for the payment of 
      taxes at such times as any Member would be required to pay federal 
      estimated taxes in an amount not in excess of the Company's good faith 
      estimate of the aggregate tax liability of the Members for the period 
      to which such estimated taxes relate as a result of allocations of Net 
      Income pursuant to section 5.1(a)(iii)-(vii); provided, any such 
      distribution under this Section 5.3(b)(i) shall reduce any distribution 
      under Section 5.3(a)(iii) which is computed with respect to the same 
      taxable year;

         (ii) no distribution shall be made to any Member if such Member, as 
      a result thereof, would receive distributions in excess of 20 percent 
      of the Company's Net Income for the taxable year to which the 
      distribution relates; provided any amounts not distributed pursuant to 
      this Section 5.3(b)(ii) shall be distributed to the other Members in 
      accordance with their respective Common Interests (which distribution 
      shall again be subject to the limitation contained in this Section 
      5.3(b)(ii));

         (iii)     no distributions shall be made under Section 5.3(a) if

    6.1  MANAGEMENT BY MEMBERS.  The business and affairs of the Company shall
be managed under the direction of an Advisory Committee, as hereinafter

otherwise provided in this Agreement, the Advisory Committee shall have full
authority to manage and supervise the business, affairs and properties of the
Company, to make all other decisions regarding the same and to perform any and

shall be composed of eleven members (collectively, the "Representatives"); 
PROVIDED, that the number of Representatives may be increased up to a total of 
18 with the written consent of Members holding at least a majority of the 
Common Units then outstanding.  Each Member shall act only through the 
Representatives. The initial Representatives shall be nominated by the 
Management Investors and shall be elected by a majority vote of all of the 
Members voting in accordance with their respective Common Interests, which 
voting shall not be cumulative. Representatives need not be residents of the 
State of Delaware.  Except with the unconditioned written consent of the

status, of a securities exchange shall be a Representative.  Each 
Representative shall have the obligations to the Members of a partner of a 
general partnership but such obligations shall not be a limitation on Section

"associated with" another Person if such first Person is a partner, officer, 
director, branch manager or employee of such second Person (or any person 
occupying a similar status or performing similar functions), or directly or 
indirectly controls, is controlled by, or is under common control with such 
second person.

         (b)  Each Representative shall be entitled to hold office until death,
resignation or removal.  Any Representative may be removed, with or without
cause, only by a majority vote of all Members voting in accordance with their
respective Common Interests, and the right of removal may be exercised at any
time.  In the event the position of a Representative becomes vacant (including
as a result of an increase in the number of Representatives) a replacement shall
be nominated by agreement of the Advisory Committee and shall be elected by a
majority vote of all the Members voting in accordance with their respective
Common Interests.

shall be kept and retained in the records of the Company.

         (b)  Any action permitted or required by applicable law or this
Agreement to be taken at a meeting of the Advisory Committee may be taken

force and effect as a vote at a meeting and may be stated as such in any
document or instrument filed with the Secretary of State, and the execution of
such consent shall constitute attendance or presence in person at a meeting of
the Advisory Committee.  Subject to the requirements of this Agreement for
notices of special meetings, Representatives may participate in and hold a

provisions hereof.  Each Member acknowledges that disclosure of information 
in violation of the provisions of this Section 7.4 may cause irreparable 
injury to the Company and the Members for which monetary damages are 
inadequate, difficult to compute or both. Accordingly, each Member agrees 
that its obligations under this Section 7.4 may be enforced by specific

the Buy Out Date, as applicable, except for the rights set forth in Section 10.2
or expressly set forth in any other agreement (including an employment
agreement) the Member designated in the applicable notice (the "Resigning
Member") (and all Persons claiming by, through or under such Member) shall have
no further rights or interests in and in respect of the Company, including any
Membership Interest, any rights in specific Company property or any rights
against the Company or any Member.

    10.2 PURCHASE PRICE.

         (a)  In consideration of the resignation of the Resigning Member, the
Company shall pay to the Resigning Member a purchase price (the "Purchase
Price") equal to the sum of (i) the product obtained by multiplying $10 times
the number of Preferred A Units and/or Preferred B Units then held by the
resigning Member, plus (ii) the product obtained by multiplying the Company's
Members' equity attributable to Common Units shown on the Company's most recent
financial statement (which may not be as of a date more than 30 days prior to
the Buy Out Date) by the Resigning Member's Common Interest.

         (b)  The payment of the Purchase Price as a result of the resignation
of a Member pursuant to Section 10.1(i) may be paid, at the Company's sole
discretion, by delivery to the Resigning Member of the Company's subordinated
promissory note, in substantially the form of Exhibit 10.2(b) hereto, paying
interest at the Broker Call Rate

<PAGE>
                                       -48-

and maturing no later than two years after the Resignation Date or Buy-Out 
Date, as applicable.  Notwithstanding anything to the contrary contained 
herein, no payment shall be made pursuant to this Article X (whether or not 
upon the maturation of the Company's subordinated note) except at such time 
as such payment is permitted by regulatory requirements (including Net 
Capital Requirements) to which the Company or any of its subsidiaries are 
subject ("Regulatory Requirements").  If the payment of the Purchase Price as 
a result of the resignation of a Member pursuant to Section 10.1(ii) is 
restricted by Regulatory Requirements, the Company shall pay such Purchase 
Price by delivery to the Resigning Member of the Company's subordinated 
promissory note, in substantially the form of Exhibit 10.2(b) hereto, paying 
interest at the Broker Call Rate and maturing no later than the date 15 days 
after the payment thereon is no longer restricted by Regulatory Requirements, 
but subject to the ordering of payments set forth in the next sentence.  If 
payments with respect to any subordinated notes issued by the Company 
pursuant to this Section 10.2(b) are restricted by regulatory requirements, 
such payments shall be made when permitted with respect to such notes in 
order of their respective issuance dates; PROVIDED, that all notes issued 
pursuant to the immediately preceding sentence shall be paid in full before 
any payments are made with respect to any notes issued pursuant to the first 
sentence of this Section 10.2(b).

    10.3 OTHER RESIGNATIONS.  No Member shall have any right to, or shall,
resign from the Company as a Member prior to the dissolution and winding up of
the Company, except in accordance with the provisions of this Article X.

                                     CONVERSIONS
                                           
    11.1 CONVERSION OF PREFERRED A UNITS.  On and after the fifth anniversary
of the Effective Date, at the option of any Preferred A Holder, such Member may
elect (by providing written notice thereof to the Company) to convert any
Preferred A Units not previously redeemed pursuant to Section 5.3(a)(iv) and
then held by such Member, into Common Units at the rate of one Common Unit for
each Preferred A Unit converted.

    11.2 EFFECTIVE DATE.  Any election made pursuant to Section 11.1 shall be
effective as of the close of business on the day the notice of such election is
received by the

<PAGE>
                                       -49-

Company.  Following a conversion by a Preferred A Holder, such converting 
Member shall no longer be treated as a Preferred A Holder for any purpose, 
including the right to receive distributions pursuant to Sections 5.3(a)(i) 
and (iv) or 12.2(b)(iv).  
                                           
                                           
                                     ARTICLE XII
                       DISSOLUTION, LIQUIDATION AND TERMINATION
                                           
    12.1 DISSOLUTION.  The Company shall be dissolved and its affairs shall be
wound up upon the first to occur of any of the following:

         (a)  The written consent of all the Members;

         (b)  The entry of a decree of judicial dissolution under Section 
18-802 of the Act;

         (c)  If (i) any Member shall dissolve or become a Resigning Member or
Bankrupt Member, or any other event shall occur that terminates the continued
membership of a Member in the Company under Section 18-801(4) of the Act;
PROVIDED, that the Company shall be continued if there are at least two
remaining Members and such remaining Members owning a majority of the profits
interests and the capital interests in the Company agree to continue the
business of the Company within the meaning of Section 18-801(4) of the Act;

         (d)  The Disposition of all, or substantially all, the Membership
Interests held by all Members or the Disposition of all, or substantially all,
the assets of the Company; or

         (e)  the date fixed in the Certificate as the latest date on which the
Company is to dissolve.

    12.2 LIQUIDATION AND TERMINATION.  On dissolution of the Company, unless it
is reconstituted and continued as provided in Section 12.1(c), the Advisory
Committee shall act as liquidator or may appoint one or more other Persons as
liquidator.  The liquidator shall proceed diligently to wind up the affairs of
the Company and make final

<PAGE>
                                       -50-

distributions as provided herein and in the Act by the end of the taxable 
year of the company in which its liquidation (as such term is defined in 
Treas. Reg. Section 1.704-1(b)(2)(ii)(g)) occurs or, if later, within 90 
Business Days of the date of such liquidation.  The costs of liquidation 
shall be borne as a Company expense.  Until final distribution, the 
Liquidator shall continue to operate the Company properties with all of the 
power and authority of the Members and the Advisory Committee.  The steps to 
be accomplished by the Liquidator are as follows:

         (a)  As promptly as possible after dissolution and again after final
liquidation, the Liquidator shall cause a proper accounting to be made by one of
the "big five" nationally recognized firms of certified public accountants of
the Company's assets, liabilities and operations through the last day of the
calendar month in which the dissolution shall occur or the final liquidation
shall be completed, as applicable; 

         (b)  The Liquidator shall have full power and authority to sell,
assign and encumber any or all of the Company's assets and to wind up and
liquidate the affairs of the Company in an orderly and business-like manner. 
All proceeds from liquidation shall be distributed in the following order of
priority:

                    (i) to the payment of the debts and liabilities of the 
               Company, to persons other than Members (but, in the case of 
               nonrecourse debts and liabilities, only to the extent required
               under the applicable credit and security agreement) and expenses
               of liquidation;

                    (ii) to the setting up of such reserves as the Liquidator 
               may reasonably deem necessary for any contingent liability of 
               the Company;

                    (iii) to the payment of any debts or liabilities of the 
               Company to Members;

                    (iv) to each Preferred A Holder in an amount equal to the 
               sum of (A) the Preferred A Holder's Unrecovered Preferred 
               Capital Amount (or a proportionate amount thereof) plus (B) the

<PAGE>
                                       -51-

      Preferred A Holder's Preference Amount for the taxable period in which 
      the liquidation occurs;

          (v) to each Preferred B Holder in an amount equal to the sum of (A) 
      the Preferred B Holder's Unrecovered Preferred Capital Amount (or a 
      proportionate amount thereof) plus (B) the Preferred B Holder's 
      Preference Amount for the taxable period in which the liquidation 
      occurs; and

         (vi) pro rata to the Members in accordance with the positive 
      balances in their Capital Accounts (as determined after taking into 
      account the distributions provided for in Section 12.2(b)(iv) and (v), 
      and other adjustments required under Treasury Regulation Section 
      1.704-1(b)(2)(ii)(b)(2)).

         (c)  Notwithstanding the provisions of this Section 12.2 which require
the liquidation of the assets of the Company, but subject to the order of
priorities set forth above, if prior to or upon dissolution of the Company the
Liquidator determines that an immediate sale of part or all of the Company's
assets would be impractical or would cause undue loss to the Members, the
Liquidator may, in its reasonable discretion, defer for a reasonable time the
liquidation of any assets except those necessary to satisfy liabilities of the
Company (other than those to Members as creditors).

    12.3 DISTRIBUTION IN KIND.  If the Liquidator shall determine that all or a
portion of the Company's assets should be distributed in kind to the Members,
the Liquidator, on behalf of the Company, shall obtain an independent appraisal
of the fair market value of each such asset as of a date reasonably close to the
date of liquidation.  Any unrealized appreciation or depreciation with respect
to such assets shall be allocated among the Members' Capital Accounts (in
accordance with Article V, assuming that the assets of the Company were sold for
such appraised fair market value) and distribution of any such assets in kind to
a Member shall be considered a distribution of an amount equal to the assets'
appraised fair market value for purposes of Section 12.2.

    12.4 DEFICIT CAPITAL ACCOUNTS.  Notwithstanding any other provision hereof
to the contrary, to the extent that a deficit, if any, exists in the Capital
Account of any Member,

<PAGE>
                                       -52-

such deficit shall not be an asset of the Company and such Member shall not 
be obligated to contribute such amount to the Company to bring the balance of 
such Member's Capital Account to zero.

    12.5 CANCELLATION OF FILINGS.  Upon completion of the distribution of
Company assets a provided herein, the Company is terminated, and the Liquidator
shall file a certificate of cancellation with the Secretary of State, cancel any
other filings made pursuant to Section 2.5 and take such other actions as may be
necessary to terminate the Company.


                                     ARTICLE XIII
                                  GENERAL PROVISIONS
                                           
    13.1 OFFSET.  Whenever the Company is to pay any sum to any Member, any
amounts that Member owes the Company may be deducted from that sum before
payment.

    13.2 NOTICES.  All notices and other communications (collectively,
"notices") provided for or permitted to be given under this Agreement shall be
in writing and shall be given by depositing the notice in the United States
mail, addressed to the Person to be notified, postage paid and registered or
certified with return receipt requested, or by such notice being delivered in
person or by facsimile communication to such party.  Unless otherwise expressly
set forth herein, notices given or served pursuant hereto shall be effective
upon receipt by the Person to be notified.  All notices to be sent to a Member
shall be sent to or made at, and all payments hereunder shall be made at, the
address set forth on Schedule A hereto or such other address as that Member may
specify by notice to the Company.  Any notice to the Company or the Advisory
Committee shall be given to all Representatives.  The address of a
Representative shall, unless notice to the contrary is given by a Representative
to the Company and the Members, be the same as the address of the Company.

    13.3 ENTIRE AGREEMENT; WAIVERS AND MODIFICATIONS.

         (a)  This Agreement constitutes the entire agreement of the Members
and their Affiliates relating to the Company and supersedes any and all prior
contracts,

<PAGE>
                                       -53-

understandings, negotiations and agreements with respect to the Company and 
the subject matter hereof, whether oral or written.

         (b)  This Agreement and the Certificate may be amended or modified
from time to time only by a written instrument executed by Members holding at
least two-thirds of the Common Units then outstanding, except, to the extent
permitted by the Act, for ministerial changes and changes necessitated by the
admission of new Members, in each case as approved by the Advisory Committee;
PROVIDED, HOWEVER, that no amendment to this Agreement shall be permitted which
impacts the rights of any Member with respect to voting, capital contributions,
allocations, distributions or this Section 13.3(b) without the express, prior,
written consent of such Member.

         (c)  Any waiver or consent, express, implied or deemed, to or of any
breach or default by any Person in the performance by that Person of its
obligations with respect to the Company or any action inconsistent with this
Agreement is not a waiver of or consent to any other breach or default in the
performance by that Person of the same or any other obligations of that Person
with respect to the Company or any other such action.  Failure on the part of a
Person to complain of any act of any Person or to declare any Person in default
with respect to the Company, irrespective of how long that failure continues,
does not constitute a waiver by that Person of its rights with respect to that
default until the applicable statute-of-limitations period has run.  Except with
respect to the matters described in the first sentence of this Section 13.3(c),
all waivers and consents hereunder shall be in writing and shall be delivered to
the other Members in the manner set forth in Section 13.2.

    13.4 BINDING EFFECT; NO THIRD-PARTY BENEFICIARIES.  Subject to the
restrictions on Dispositions set forth herein, this Agreement is binding on and
inures to the benefit of the Members and their respective heirs, legal
representatives, successors and assigns.  Nothing in this Agreement shall
provide any benefit to any third party or entitle any third party to any claim,
cause of action, remedy or right of any kind, it being the intent of the parties
that this Agreement shall not be construed as a third-party beneficiary
contract.

    13.5 GOVERNING LAW.  This agreement is governed by and shall be construed 
in accordance with the law of the state of Delaware, excluding any 
conflict-of-laws rule or principle that might refer the governance or 
construction of this agreement to the law of

<PAGE>
                                       -54-

another jurisdiction.  If any provision of this Agreement or the application 
thereof to any Person or circumstance is held invalid or unenforceable to any 
extent, the remainder of this Agreement and the application of that provision 
shall be enforced to the greatest extent permitted by law.

    13.6 FURTHER ASSURANCES.  In connection with this Agreement and the
transactions contemplated hereby, each Member shall execute and deliver any
additional documents and instruments and perform any additional acts that may be
necessary or appropriate to effectuate and perform the provisions of this
Agreement and those transactions.

    13.7 WAIVER OF CERTAIN RIGHTS.  Each Member irrevocably waives any right
(but not any power) it might have to maintain any action for dissolution of the
company or for partition of the property of the Company.  If any Member
maintains any action for such dissolution or partition, such Member shall be
liable to the Company and the other Members for all monetary damages suffered by
them as a result thereof (including, indirect, incidental and consequential
damages).  

    13.8 MULTIPLE COUNTERPARTS.  This Agreement may be executed in multiple
counterparts with the same effect as if each of the signing parties had signed
the same document.  All counterparts shall be construed together and constitute
the same instrument.

    13.9 SUCCESSOR AND ASSIGNS.  Subject to the limitations and restrictions
set forth in this Agreement, this Agreement shall be binding on and insure to
the benefit of the successors and assigns of the Membership Interests of the
parties hereto.

<PAGE>
                                       -55-

    IN WITNESS WHEREOF, the Members have executed this Agreement as of the date
first set forth above.

                               PURCHASE AGREEMENT


     THIS AGREEMENT is made as of June 28, 1995, between Telescan, Inc., a
Delaware corporation (the "Company"), and TransTerra Company, a Nebraska
corporation (the "Purchaser").  Except as otherwise indicated herein,
capitalized terms used herein are defined in Section 6 hereof.

     The parties hereto agree as follows:

          Section 1.  AUTHORIZATION AND CLOSINGS.

          1.01 AUTHORIZATION OF THE COMMON STOCK.  The Company shall authorize
the issuance and sale to the Purchaser of a number of shares of its Common
Stock, par value $.01 per share (the "Common Stock"), necessary to fulfill its
obligations pursuant to this Agreement.

          1.02 PURCHASE AND SALE OF THE COMMON STOCK.  At each Closing, the
Company shall sell to the Purchaser and, subject to the terms and conditions set
forth herein, the Purchaser shall purchase from the Company, the number of
shares of Common Stock set forth opposite such Closing under the heading "Number
of Shares" on the "Schedule of Purchases" attached hereto.  The sale of Common
Stock to the Purchaser at each Closing shall constitute a separate sale
hereunder.

duly organized, validly existing and in good standing under the laws of Delaware

qualify would reasonably be expected to have a material adverse effect on the

Company and its Subsidiaries taken as a whole (a "Material Adverse Effect").
The Company has all requisite corporate power and authority and all material
licenses, permits and authorizations necessary to own and operate its

     (ii) There are no statutory or, to the best of the Company's knowledge,
contractual stockholders preemptive rights or rights of refusal with respect to
the issuance of the Common Stock hereunder. The Company has not violated any
applicable federal or state securities laws in connection with the offer, sale
or issuance of any of its capital stock, and the offer, sale and issuance of the
Common Stock hereunder do not require registration under the Securities Act or
any applicable state securities laws.  To the best of the Company's knowledge,
there are no agreements between


                                       -5-

performance of this Agreement and the Registration Agreement have been duly

to which the Company or any Subsidiary is subject, or any agreement, instrument,
order, judgment or decree to which the Company or any Subsidiary is subject,
except where any such occurrence described in clauses (i) through (v) above
would not have a Material Adverse Effect.

          WHEREAS, the parties hereto desire that Buyer purchase all of the
outstanding capital stock and other securities of K. Aufhauser & Company Inc., a
New York corporation (the "Company"), from Seller.

          NOW, THEREFORE, in consideration of the payment of $1.00 and other
good and valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties hereby covenant and agree as follows:

which shall constitute all of the outstanding shares of the capital stock of the
Company.

          1.2  PURCHASE PRICE.  The purchase price for the Stock (the "Purchase
Price") shall be an amount equal to $7,300,000.  The Purchase Price shall be
paid by wire transfer at the Closing in immediately available funds to an
account designated by Seller ("Seller's Account").

          1.3  EXISTING LIABILITIES.  It is the parties' intent that the Seller
pay all liabilities of the Company existing as of the Closing or arising
thereafter and relating to the operation of the Company prior to the Closing,
including without limitation liabilities for taxes (and tax returns) through 
the Closing and the items listed on the SCHEDULE OF CLAIMS AND LITIGATIONS 
(the "Existing Liabilities").  As a result, immediately prior to the Closing 
the Company, acting on behalf of the Seller, and the Buyer shall use all 
reasonable efforts to estimate the Existing Liabilities and the amount of 
that estimate shall be withheld

<PAGE>

from the cash payment described in SECTION 1.2(a) above.  The amount of any
other Existing Liabilities shall be promptly reimbursed to Buyer by Seller.

          1.4  NO OTHER OBLIGATIONS.  Buyer shall have no responsibility for any
liabilities or obligations of Seller of any nature whatsoever, whether now
existing or hereafter arising, attributable to any period prior to the Closing,
and whether known or unknown to Buyer.

          1.5  CLOSING.  The consummation of the purchase and sale herein
contemplated (the "Closing") shall take place at 10:15 o'clock a.m., local time,
at the offices of Schiff Hardin & Waite, 150 East 52nd Street, New York, New
York 10022, July 10, 1995 or as soon thereafter as all of the conditions to the
Closing specified in this Agreement shall have been fulfilled or waived by the
party or parties entitled to such fulfillment or such other date as the parties
may mutually agree (the "Closing Date").

          1.6  PAYMENT FOLLOWING CLOSING.  Following the Closing, Seller
promptly shall reimburse the Company for all existing liabilities for which
funds were not withheld pursuant to SECTION 1.3 above.  Following the Closing,
Buyer promptly shall pay Seller all tangible assets in excess of $300,000 that
existed as of the closing as such assets are received.


          SECTION 2.  REPRESENTATIONS AND WARRANTIES OF SELLER.  Seller hereby
represents and warrants to Buyer as follows:

          2.1  CORPORATE EXISTENCE; CAPITAL STOCK.  The Company is a corporation
duly organized, validly existing and in good standing under the laws of New
York, has corporate power to own its properties and to carry on its business as
now being conducted, and is duly qualified and in good standing as a foreign
corporation in every jurisdiction where the failure to be qualified would
adversely affect its ownership of its properties or the conduct of its business
in any material respect.  The Company has no subsidiaries.  The authorized
capital stock of the Company consists of 200 shares, of which 25 are issued and
outstanding (those being the shares which comprise the Stock).  Except for this
Agreement


                                        2
<PAGE>

and an option dated January 2, 1994, in favor of Lucky Coin (which option shall
be canceled upon the payment described in SECTION 1.2 above) (the "Option"),
there are no options, warrants, preemptive rights, conversion privileges or
other contracts which give any person or entity the right to acquire any capital
stock of the Company, whether from the Company, Seller or otherwise.

          2.2  CORPORATE DOCUMENTS.  Seller has furnished Buyer with a copy of
the Company's charter certified as of a recent date by the New York Secretary of
State, and a copy of the Company's bylaws of the Company certified as of a
recent date by the Secretary of the Company.  Both documents are complete and
correct and reflect all amendments thereto as of the date of certification.

          2.3  AUTHORIZATION OF AGREEMENT.  Seller has the full legal right and
power to execute, deliver and perform this Agreement and to consummate the
transactions herein contemplated, and such execution, delivery and performance
do not violate (and do not, automatically or at the election of a third party,
result in the modification of the terms of) any provisions of the charter or
bylaws of the Company, or any agreement to which Seller or the Company is a
party or is otherwise bound or any order, decree, judgment, statute, rule or
regulation applicable to Seller or the Company.

          2.4  FINANCIAL STATEMENTS. Seller has furnished Buyer with (a) balance
sheets of the Company as of December 31, 1994 (the "1994 Year-End Balance
Sheet") and 1993, and the related statements of income, stockholders equity and
cash flows for the years then ended (collectively, the "Financial Statements")
and (b) a balance sheet of the Company as of May 31, 1995, and the related
statement of income for the five-month period then ended (collectively, the
"Interim Statements"), together with respect to the Financial Statements, the
unqualified reports thereon of Breiner & Bodian, independent public accountant
for the Company.  The Financial Statements and Interim Statements have been
prepared in accordance with generally accepted accounting principles ("GAAP")
consistently applied and, together with the notes thereto, present fairly the
financial position of the Company at the dates


                                        3
<PAGE>

shown and the results of operations for the periods then ended, except that the
Interim Statements do not contain customary year-end adjustments.

          2.5  UNDISCLOSED LIABILITIES.  Except as listed on the SCHEDULE OF
MATERIAL LIABILITIES, since December 31, 1994, the Company has not incurred or
suffered any material liabilities (whether accrued, absolute, contingent or
otherwise) that exist or arise out of any transaction or state of facts existing
on or prior to the date hereof other than (a) as and to the extent reflected or
reserved against on the face of the 1994 Year-End Balance Sheet (and not solely
in a footnote thereto), and (b) as and to the extent incurred in the ordinary
course of business (i.e., not including liabilities for breaches of contracts or
violations of law) consistent with past practices after December 31, 1994 and
with the expectation of a normal profit.

          2.6  NO ADVERSE CHANGES.  Except as indicated in the SCHEDULE OF
ADVERSE CHANGES, there has not occurred (a) any materially adverse change since
December 31, 1994 in the business, relationship with any material customer or
with the Pershing Division of Donaldson, Lufkin and Jenrette Securities
Corporation, sales, income, profit margins, assets, liabilities or financial
condition of the Company; (b) any condition, event, circumstance, fact or other
occurrence, whether occurring before or since December 31, 1994, that may
reasonably be expected to have or result in such a materially adverse change; or
(c) any damage, destruction or loss since December 31, 1994, whether or not
covered by insurance, materially and adversely affecting the assets or business
of the Company.

          2.7  SERVICES.  The only product or service ever produced by the
Company is the provision of discount stock, bond and option brokerage services
(with the exception of certain clients listed on the SCHEDULE OF RUBY LIN'S
CLIENTS and on the SCHEDULE OF ROBERT LEE BULL'S CLIENTS who may be considered
non-discount clients), and the Company has provided those services in conformity
with all applicable laws, ordinances, regulations, trade and industry standards
and customer specifications now in effect.  Seller has furnished to Buyer a
SCHEDULE OF CLAIMS AND LITIGATIONS which accurately describes


                                        4
<PAGE>

all customer and other claims made and related to the conduct of the business of
the Company since January 1, 1990 and the resolution thereof.  The Company is a
member in good standing of the National Association of Securities Dealers, Inc.
Seller is not a member of any securities exchange.

          2.8  CONDUCT OF BUSINESS IN NORMAL COURSE.  (a) Subject to SECTION
2.8(b), the business of the Company has, since December 31, 1994, been conducted
only in the usual and ordinary course consistent with past practice.  As of the
Closing, the Company will have a net book value of not less than $300,000
(following any dividends) computed pursuant to GAAP and satisfying the
regulatory net capital requirements.  Except as indicated in the SCHEDULE OF
BUSINESS INFORMATION, or reflected on the ADP Report for May 1995, since January
1, 1995, no change has been made in compensation of officers and employees, and
no commitment has been made therefor, whose annual rate of compensation exceeds
$20,000 and, except as contemplated hereby, the Company has not paid (or
declared) any bonus or dividend.  All transactions between the Company and its
stockholders, officers, directors, employees (and their family members) since
January 1, 1990 have been on terms no less favorable than those available from
unrelated third parties and are properly reflected in the financial records of
the Company.  As of May 31, 1995, the Company had in excess of 11,000 customer
accounts on record of which more than 8,000 had positive equity as of the
purchase date.  The trading activity of the Company's accounts since January 1,
1995 through June 30, 1995 is indicated in the Pershing Monthly Commission
Summary.  The debit balances, credit balances, money fund balances and long and
short securities positions of the Company's clients as of July 7, 1995 are as
appears on the Pershing MoneyLine Report.  The Pershing High Liability Account
Report, as of July 7, 1995, indicates accounts which merit special attention 
with an eye to monitor risks.  The July 7, 1995 Pershing Concentration Report
indicates accounts with unusual (and perhaps risky) concentrations of
securities.  The audited financials for the years 1992, 1993, and 1994, and the
two most recent quarterly FOCUS reports for the Company have been delivered to
Buyer.

          (b)  Notwithstanding the foregoing, the Company shall be entitled to
dividend (or pay out as salary, bonus, or otherwise) to its stockholder
immediately prior to the Closing its cash on hand


                                        5
<PAGE>

(other than the $300,000 in cash net capital) and securities and fixed assets
listed on EXHIBIT A hereto which shall include the Company's contract with
Digitrade (but not the fixed assets used in the ordinary course of the Company's
business).

          2.9  PROPERTIES AND ASSETS.  The Company has good and marketable title
to all of its assets free and clear of any and all liens, claims, restrictions,
charges or encumbrances of any kind or character, other than (a) liens of
current taxes not delinquent as to payment; or (b) liens or interests of others
arising under contracts and commitments listed in the SCHEDULE OF CONTRACTS
(other than as a result of breaches thereof).  All assets used in the operation
(or necessary for the continued operation) of the business of the Company are
either owned by the Company or leased pursuant to leases set forth on the
SCHEDULE OF CONTRACTS.  Except for the Option, which shall be canceled prior to
the Closing, Seller owns all outstanding equity interests in the Company free
and clear of any liens, claims, encumbrances or other rights, and there are no
rights to purchase equity securities of the Company or other securities
convertible into or exercisable for any equity securities of the Company.  The
assets of the company include the account papers for each of the 11,000 plus
customer accounts (and records regarding the approximately 10,000 respondents to
advertising who did not open accounts) and are sufficient so that following the
Closing the Company will be in compliance with all record keeping requirements.

          2.10 ACCOUNTS RECEIVABLE.  All of the Company's accounts receivable
result from the provision of brokerage services by the Company in the ordinary
course of its business.  Except for the rights of Pershing to assert a setoff
pursuant to exchange rules or the other agreements between Pershing and the
Company, no obligor has any right to a credit, setoff or offset against any of
the accounts receivable, and all of the accounts receivable are collectible in
full with ordinary efforts within ninety days.

          2.11 PATENTS, TRADEMARKS, ETC.  The Company does not infringe any
patent, license, copyright, trademark or other right owned by any other person.
The SCHEDULE OF PROPRIETARY RIGHTS is complete and lists all patents,
trademarks, trade names, copyrights and applications therefor owned by


                                        6
<PAGE>

the Company or by others whereunder the Company has been licensed or has
acquired other rights; and all contracts and assignments relating thereto are
listed in the SCHEDULE OF CONTRACTS.

          2.12 CONTRACTS.  Except as listed on the SCHEDULE OF CONTRACTS: (a)
the Company is not a party to, or obligated under, any contract, lease for real
or personal property, arrangement, program or commitment pertaining to the
operations of the business of the Company (including, but not limited to, any
price sheets, advertising allowances, rebates or discounts) that provides for
aggregate payments in excess of U.S. $5,000 during its remaining term, except
for contracts for the purchase or sale of goods and services entered into in the
ordinary course of the business of the Company consistent with past practice and
either scheduled to be fulfilled within the next 90 days or terminable on 90 or
fewer days notice without penalty to the Company; (b) the Company has fulfilled,
or taken all action reasonably necessary to enable it to fulfill when due, all
material obligations of the Company under the contracts listed on the SCHEDULE
OF CONTRACTS; (c) there has not occurred any default, or any event which with
the lapse of time or the election of any person, or both, will become a default,
under any such contract; (d) all such contracts are legal, valid and binding
upon the Company and, to the knowledge of Seller, upon the other parties
thereto, and are in full force and effect.  The Fully Disclosed Clearing
Agreement between the Company and Pershing is not terminable as a result of the
consummation of the transaction contemplated hereby.  Seller and Pershing have
agreed that a change in ownership of the Company would not cause the termination
of the Fully Disclosed Clearing Agreement between the Company and Pershing and
that as soon after the Closing as requested by the Company, Pershing will
cooperate fully with a bulk transfer of all of the accounts to an affiliate of
Buyer.  (See SCHEDULE OF MISCELLANEOUS CORRESPONDENCE.)

          2.13 LITIGATION AND COMPLIANCE WITH CERTAIN LAWS.  Except as disclosed

the Company, at law or in equity, or before any federal, state, municipal or
other governmental authority, or before any arbitrator or arbitration panel,
whether by contract or otherwise;

CORRESPONDENCE) there is no decree, judgment or order of any kind in existence
restraining the Company, or any of its officers, employees, or directors, from
taking any actions of any kind in connection with the business of the Company;

decrees applicable to it, its business, or its assets; and (d) the Company has
not received any written notice of any claim that it is not in compliance
therewith.

of the Company's annual revenue during 1993, 1994, or the first four months of
1995.

          2.16 TAXES.  All tax returns required to be filed by the Company with
any federal, territorial state, local or other governmental unit have been or

respects.  No application for extension of time for filing any tax return or
consent to any extension of the period of limitations applicable to the
assessment or collection any tax is in effect or will, prior to the date of the
Closing, have been made by the Company without the written consent of Buyer.
The Company is not delinquent in the payment of any taxes claimed to be due by
any taxing authority.

          2.17 EMPLOYEE BENEFITS.  Except as described on the SCHEDULE OF

contracts,


                                        8

agreements and plans, if any.  All social security returns required to be filed
by the Company with any federal, territorial, state, local, or other
governmental unit have been or will be timely filed and were or are accurate and
complete in all material respects.  No application for extension of time for
filing any social security return or consent to any extension of the period of

effect or will, prior to the date of the Closing, have been made by the Company
without the written consent of Buyer.  The Company is not delinquent to the
payment of any charges claimed to be due by any social security authority.

          2.18 ENVIRONMENTAL MATTERS.  The Company is not in violation of any

or any other entity which is authorized by law to issue orders under any
Environmental Law ("Environmental Agency") or from anyone else.  If the Seller
or the Company receives (a) any notice of an Environmental Event affecting the
Company or its assets, or (b) any notice of an Environmental Action from any
Environmental Agency or from anyone else, Seller shall give, within seven (7)
days, written notice thereof to Buyer.  The Company has all certificates,
licenses and permits (the "Permits") necessary under Environmental Laws


                                        9
<PAGE>

for the Company to conduct its operations.  No underground storage tanks exist

of Buyer in conformity with all requirements of Buyer's bylaws and Certificate
of Incorporation and applicable law.  Buyer has full corporate power to execute,

provisions of the Certificate of Incorporation or bylaws of Buyer, or any
agreement to which Buyer is a party or is otherwise bound and which is material
to any business of Buyer or any order, decree, judgment, statute, rule or
regulation applicable to Buyer, the violation of which might have a materially
adverse effect on any business of Buyer.

          Seller hereby covenants that the following shall apply beginning on
the Closing Date and thereafter where applicable:

affirmation of the truth and correctness as of the Closing of the
representations and warranties of Buyer and Seller contained in this Agreement;

such representations, warranties or agreements shall not be a defense to a claim

circumstances giving rise to any claims by Buyer under this Section, (ii)
subject to the limitations of any contract of insurance, Buyer shall tender to
Seller the opportunity to manage and control any defense against any such claim,
it being understood that Buyer may participate at its expense in any such
defense assumed by Seller and that the assumption of management and control of
any such defense shall not, itself, constitute any admission by Seller of
liability to Buyer or to any other entity, (iii) Buyer shall cooperate
reasonably with Seller in the prosecution of any such defense, and (iv) Buyer
shall not compromise or settle any such claim without the prior written consent
of Seller which shall not be unreasonably withheld.

be subject to written notice of the matter giving rise to such potential

statutes of limitation.

          5.4  INDEMNIFICATION BY BUYER.  Buyer shall indemnify Seller against
and hold Seller harmless from any and all loss, cost, damage or expense arising
out of or resulting from (a) breach or incorrectness of any of the

this Section, (ii) subject to the limitations of any contract of insurance,
Seller shall tender to Buyer the opportunity to manage and control and defend
against any such claim, it being understood that Seller may participate at its
expense in any such defense assumed by Buyer and that the assumption of
management and control of any such defense shall not, itself, constitute any
admission by Buyer of liability to Seller or to any other entity, (iii) Seller
shall cooperate reasonably with Buyer in the prosecution of any such defense,
and (iv) Seller shall not compromise or settle any such claim without the prior
written consent of Buyer which shall not be unreasonably withheld.

          SECTION 6.  GENERAL

          6.1  FURTHER ASSURANCES.  Each party hereto agrees that at any time
and from time to time after the Closing they will execute and deliver to the

    obligations of whatever nature and whenever incurred to Company") shall not
    be affected by any of the following:

       - Acceptance or retention by Company of other property or interests
         as security for the Obligations, or for the liability of any
         person other than a Maker with respect to the Obligations;

         any of the Obligations or the liability of any obligator thereon;

         liable for the Obligations.

    Each Maker specifically consents to multiple renewals or extensions of the
    Obligations.  This Note shall be deemed extended through the date of any
    advance made by Company after the original maturity hereof; and any such
    advance shall constitute principal due under this Note.

2.  REPRESENTATION, WARRANTIES AND COVENANTS.  Each Maker represents, warrants
    and covenants as follows:

    This Note and the real estate lien or mortgage, if any, securing the Note
    have been duly authorized, executed and delivered by the Maker and
    constitute legal, valid and binding Obligations of Maker.

    This Note evidences a loan for business or agricultural purposes.

         in this Note or the other Obligations; or breaches any other
         covenant or condition described in any other document;

       - Any Maker, endorser, surety, or guarantor of any of the

         benefit of creditors, becomes insolvent or the subject of
         bankruptcy or insolvency proceedings;

       - Any representation made to induce Company to extend credit under
         this Note or otherwise is false in any material respect when
         made;

    and without notice or demand, mature and become immediately due and
    payable; and Company shall have all rights and remedies for default
    provided by the Uniform Commercial Code, and any other applicable law
    and/or the Obligations.

    All costs and expenses incurred by Company in enforcing its rights under
    this Note or any mortgage or other lien, endorsement, surety agreement,
    guarantee relating thereto are the obligations of Maker and are immediately
    due and payable.  Interest shall accrue on such costs and expenses from the
    date of incurrence at the rate specified herein for delinquent Note
    payments.  Each maker, endorser, surety and guarantor hereby waives
    presentment, protest, demand, notice of dishonor, and the defense of any
    statue of limitations.

4.  GENERAL.  Without affecting the liability of any Maker, endorser, surety,
    or guarantor, the holder may, without notice, renew or extend the time for
    payment, accept partial payments, release or impair any collateral security
    for the payment of this Note or agree to sue any party liable on it.

    or unsecured) then owed to Company by depositor or in the case of a
    multiple-party account, by any part to such multiple-party account, and
    this agreement shall be construed to be the consent of depositor and any

    required by any person or future law.

    Bank shall not be deemed to have waived any of its rights upon or under
    this Note, or under any mortgage or other lien, endorsement, surety
    agreement, or guarantee unless such waivers be in writing and signed by
    Company.  No delay or omission on the part of Company in exercising any
    right shall operate as a waiver of such right or any other right.  A waiver
    on any one occasion shall not be construed as a bar to or waiver of any
    right on any future occasion.  All rights and remedies of Company on
    liabilities or the collateral whether evidenced hereby or by any other
    instrument or papers shall be cumulative and may be exercised singularly or
    concurrently.

    applying to all future as well as existing transactions, whether or not of
    the character contemplated at the date of this Note, and if all
    transactions between Company and Maker shall be at any time closed, shall
    be equally applicable to any new transactions thereafter; shall benefit
    Company, its successors, and assigns; and shall so continue in force not
    withstanding any change in any partnership party hereto, whether such

    provisions hereof or affecting the validity or enforceability of such

                               LOAN AGREEMENT

     This Agreement, made as of the 22nd day of December, 1994, by and among 
First National Bank of Omaha ("BANK"), a national banking association with 
principal offices in Omaha, Nebraska; TRANSTERRA CO. ("BORROWER"), a Nebraska 
corporation with principal offices in Omaha, Nebraska; AmeriTrade, Inc. 
("AMERITRADE"), a Nebraska corporation with principal offices in Omaha, 
Nebraska; and John Joe Ricketts ("GUARANTOR"), a resident of Douglas County, 
Nebraska.

     This Agreement is executed contemporaneously with a revolving promissory 
note in the amount of $500,000.00 ("REVOLVING NOTE") in the form attached 
hereto as Exhibit A, a term promissory note in the amount of $1,900,000.00, 
("TERM NOTE") in the form attached hereto as Exhibit B (which, together with 
any renewals, extensions, or modifications thereof are collectively called 
"NOTES") of even date in favor of BANK by BORROWER, which are guaranteed by 
GUARANTOR.  The NOTES shall specify the manner of principal and interest 
payments and rate of interest accrual.  As collateral for the NOTES, BORROWER 
has pledged a security interest in 7,559 shares of AMERITRADE capital stock 
as evidenced by a pledge agreement in the form attached hereto as Exhibit C.

     AMERITRADE is a wholly owned subsidiary of BORROWER.  AMERITRADE has an 
interest in assuring that BORROWER obtains the loan proceeds from the TERM 
NOTE, to allow the investment by BORROWER in Roundtable Partners.  In 
consideration of BANK lending such funds to BORROWER, AMERITRADE enters into 
this Agreement.

     Now, Therefore, in consideration for the NOTES, and their mutual 
promises made herein, the parties agree as follows:

1.   MINIMUM NET CAPITAL.

     AMERITRADE shall, at all times until full repayment to BANK of any and 
all indebtedness due to BANK as the result of the NOTES, maintain net capital 
in excess of Three Million Seven Hundred Thousand ($3,700,000.00) Dollars.  
Said net capital is to be calculated according to United States Securities 
and Exchange Commission Rule 15c 3-1.  Failure to maintain such minimum net 
capital shall constitute a default sufficient to allow BANK, at its option, 
to accelerate the loan obligation represented by the NOTES.

2.   MINIMUM ALTERNATE NET CAPITAL.

     AMERITRADE shall maintain at all times until full repayment of all 
indebtedness due to BANK by BORROWER, a minimum 5% alternate net capital 
requirement of aggregate debit items as determined by United States 
Securities and Exchange Commission Rule 15c-3.  Though the Securities and 
Exchange Commission requires AMERITRADE to maintain an alternate net capital 
requirement of 2% of such debit items, nonetheless, AMERITRADE agrees to 
maintain a minimum 5% alternate capital requirement.  Failure to maintain 
such minimum net capital requirement shall constitute a default sufficient to 
allow BANK, at its option, to accelerate the loan obligation represented by 
the NOTES.



<PAGE>

3.   CERTIFICATION OF CAPITAL COMPLIANCE.

     AMERITRADE and BORROWER shall provide monthly certification of 
AMERITRADE'S compliance with the alternate minimum capital requirement by 
providing to BANK a signed copy of the documents furnished to the Securities 
and Exchange Commission, wherein AMERITRADE computes alternate capital 
requirements pursuant to United States Securities and Exchange Commission 
Rule 15c 3-1 and computation of determination of reserve requirement pursuant 
to United States Securities and Exchange Commission Rule 15c 3-3.

4.   MINIMUM NET WORTH.

     BORROWER shall, at all times until full repayment to BANK of any and all 
indebtedness due to BANK as the result of the NOTES, maintain net worth in 
excess of Seven Million Five Hundred Thousand ($7,500,000.00) Dollars.  Said 
net worth is to be calculated according to generally accepted accounting 
principles ("GAAP").  Failure to maintain such minimum net worth shall 
constitute a default in repayment sufficient to allow BANK, at its option, to 
accelerate the loan obligation represented by the NOTES.

5.   BORROWING PROHIBITION.

     Neither AMERITRADE nor BORROWER shall borrow additional funds during the 
term of the loan evidenced by the NOTES, except such loans and borrowings as 
are collateralized only by AMERITRADE'S securities, unless such additional 
borrowings are approved in writing by BANK.

6.   ALL ISSUED STOCK.

     GUARANTOR, BORROWER and AMERITRADE warrant that the capital stock of 
AMERITRADE transferred by the pledge agreement dated April 24, 1992 to BANK 
constitutes all of the issued and outstanding capital stock of AMERITRADE.

7.   NEGATIVE PLEDGE.

     Neither GUARANTOR nor BORROWER shall directly, or indirectly, sell, 
pledge, convey, or otherwise dispose of any shares of capital stock, nor all 
or any substantial part of such entity's assets.

8.   MONTHLY FINANCIAL STATEMENTS.

     AMERITRADE and BORROWER shall provide within twenty days after the close 
of each monthly accounting period in each fiscal year income statements for 
such month and balance sheets as of the close of such month in reasonable 
detail, subject to normal year-end audit adjustments prepared in accordance 
with GAAP.



<PAGE>

9.   ANNUAL FINANCIAL AUDITS.

     AMERITRADE and BORROWER shall provide BANK within ninety days after the 
close of each fiscal year income statements of such fiscal year and balance 
sheets as of the close of such fiscal year in reasonable detail, subject to 
normal year-end audit adjustments prepared in accordance with GAAP.

10.  COMMITMENT FEE.

     BORROWER shall pay to BANK on a quarterly basis a fee computed daily at 
rate of one-half percent (1/2%) of the difference between the maximum 
borrowing available under the REVOLVING LOAN and paid for the actual days 
elapsed.

11.  DEFAULT.

     If one or more of the following events shall have occurred and be 
continuing:

          a.  BORROWER shall fail to pay when due to BANK any sum required by
     NOTES;

          b.  BORROWER, GUARANTOR, or AMERITRADE shall fail to observe any
     covenant contained herein or in any other document executed in connection 
     with the NOTES;

          c.  Any material representation, warranty, certification or statement
     made by BORROWER, AMERITRADE or GUARANTOR in this Agreement or in any
     document delivered pursuant to this Agreement shall prove to be incorrect 
     in any  material respect when made or deemed made, then, in such event, 
     at the option of BANK, without further notice to BORROWER, AMERITRADE or
     GUARANTOR, the NOTES, together with accrued interest thereon shall become
     immediately due and payable without presentment, demand, protest or other
     notice of any kind, all of which are hereby waived by BORROWER,  
     AMERITRADE, and GUARANTOR.

12.  CONSENT AND RATIFICATION.

     GUARANTOR consents to this Agreement, and by his execution hereof 
ratifies and confirms his executed written guarantee of BORROWER'S 
obligations.

                             TERMS AND CONDITIONS

1. Maker shall reimburse Bank for all expenses incurred in protecting or 
   enforcing its rights.
   Maker's liability under its Obligations ("all Maker's existing and future 
   obligations of whatever nature and whenever incurred to Bank") shall not 
   be affected by any of the following:
   - Acceptance or retention by Bank of other property or interests as 
     security for the Obligations, or for the liability of any person other 
     than a Maker with respect to the Obligations;
   - Any release, extension, renewal, modification or compromise of any of 
     the Obligations or the liability of any obligor thereon; or
   - Failure by Bank to resort to other security or any person liable for the 
     Obligations.
   Each maker specifically consents to multiple renewals or extensions of the 
   Obligations. This Note shall be deemed extended through the date of any 
   advance made by Bank after the original maturity hereof; and any such advance
   shall constitute principal due under this Note.


2. REPRESENTATION, WARRANTS AND COVENANTS.  Each Maker represents, warrants 
   and covenants as follows:
   This Note, security agreement, deed of trust, mortgage, or other lien 
   document(s), if any, securing the Note have been duly authorized, executed 
   and delivered by the Maker and constitute legal, valid and binding 
   Obligations of Maker.
   This Note evidences a loan for business or agricultural purposes.
   Maker will provide business reports and with such frequency as Bank shall 
   request; and
   Maker agrees to pay all costs of collection in connection with this Note, 
   including reasonable attorneys' fees and legal expenses.


3. DEFAULTS AND REMEDIES. Upon the occurrence of one or more of the following 
   events of default:
   - Maker fails to pay when due any of the Obligations, or to perform or 
     rectify breach of, any warranty or other undertaking by Maker in this 
     Note or the other Obligations; or breaches any other covenant or condition
     described in any other document;
   - Any Maker, endorser, surety, or guarantor of any of the Obligations 
     dies, ceases to exist, makes an assignment for the benefit of creditors, 
     becomes insolvent or the subject of bankruptcy or insolvency proceedings;
   - Any representation made to induce Bank to extend credit under this Note 
     or otherwise is false in any material respect when made;
   - A material adverse change, in the opinion of Bank, occurs in the 
     financial or business condition of any Maker or of any endorser, surety or
     guarantor of this Note;
   - The entry of a judgment against any Maker;
   - Filing of any lien against any Maker;
   - The taking possession of any substantial part of the property of any 
     Maker at the instance of any governmental authority;
   - The dissolution, merger, consolidation, or reorganization of any Maker, 
     or other entity liable for this Obligation;
   - Any other event occurs which causes Bank in good faith to deem itself 
     insecure;

   then in such event, all of the Obligations shall, at the option of Bank 
   and without notice or demand, mature and become immediately due and payable;
   and Bank shall have all rights and remedies for default provided by the 
   Uniform Commercial Code, and any other applicable law and/or the Obligations.

   All costs and expenses incurred by Bank in enforcing its rights under this 
   Note or any mortgage or other lien, endorsement, surety agreement, guarantee 
   relating thereto are the obligations of Maker and are immediately due and 
   payable. Interest shall accure on such costs and expenses from the date of 
   incurrence at the rate specified herein for delinquent Note payments. Each 
   Maker, endorser, surety and guarantor hereby waives presentment, protest, 
   demand, notice of dishonor, and the defense of any statute of limitations.

4. GENERAL. Without affecting the liability of any Maker, endorser, surety, 
   or guarantor, the holder may, without notice, renew or extend the time for 
   payment, accept partial payments, release or impair any collateral security 
   for the payment of this Note or agree to sue any party liable on it.

   Subject to rights afforded by law, Bank may, at any time and for any 
   reason, charge to or off-set against any amount then on deposit in any 
   account (including a savings certificate), whether or not then due, any and
   all debts or liabilities (sole, several, joint, or joint and severable, 
   absolute or contingent, due or not due, liquidated or unliquidated, secured 
   or unsecured) then owed to Bank by depositor or in the case of a 
   multiple-party account, by any party to such multiple-party account, and 
   this agreement shall be construed to be the consent of depositor and any 
   such party for the Bank to make such charge or off-set if consent be 
   required by any person or future law.

   Bank shall not be deemed to have waived any of its rights upon or under 
   this Note, or under any mortgage or other lien, endorsement, surety 
   agreement, or guarantee unless such waivers be in writing and signed by
   Bank. No delay or omission on the part of Bank in exercising any right shall 
   operate as a waiver of such right or any other right. A waiver on any one 
   occasion shall not be construed as a bar to or waiver of any right on any 
   future occasion. All rights and remedies of Bank on liabilities or the 
   collateral whether evidenced hereby or by any other instrument or papers 
   shall be cumulative and may be exercised singularly or concurrently.

   Maker, if more than one, shall be jointly and severally liable hereunder 
   and all provisions hereof regarding the liabilities or security of Maker 
   shall apply to any liability or any security of any or all of them. This 
   agreement shall be binding upon the heirs, executors, administrators, assigns
   or successors of Maker; shall constitute a continuing agreement, applying to 
   all future as well as existing transaction, whether or not of the character 
   contemplated at the date of this Note, and if all transactions between Bank 
   and Maker shall be at any time closed, shall be equally applicable to any 
   new transactions thereafter; shall benefit Bank, its successors, and 
   assigns; and shall so continue in force notwithstanding any change in any 
   partnership party hereto, whether such change occurs through death, 
   retirement or otherwise.

   If any party of this Note is a married person, such person or persons 
   hereby separately charges his or her separate estate, including both that now
   owned and that hereafter acquired, with the payment of this Note.

   This Note shall be construed according to the laws of the State of Nebraska.

   Unless the content otherwise requires, all terms used herein which are 
   defined in the Uniform Commercial Code shall have the meanings therein 
   stated.

   Any provision of this Note which is prohibited or unenforceable in any 
   jurisdiction shall, as to such jurisdiction, be ineffective to the extent of 
   such prohibition or unenforceability without invalidating the remaining 
   provisions hereof or affecting the validity or enforceability of such 
   provision in any other jurisdiction.

   - A material adverse change, in the opinion of Bank, occurs in the financial 
     or business condition of any Maker or of any endorser, surety or guarantor
     of this Note;
   - The entry of a judgment against any Maker;
   - Filing of any lien against any Maker;
   - The taking possession of any substantial part of the property of any Maker 
     at the instance of any governmental authority;
   - The dissolution, merger, consolidation, or reorganization of any Maker, or 
     other entity liable for this Obligation;
   - Any other event occurs which causes Bank in good faith to deem itself 
     insecure;

   then in such event, all of the Obligations shall, at the option of Bank and 
   without notice or demand, mature and become immediately due and payable; and 
   Bank shall have all rights and remedies for default provided by the Uniform 
   Commercial Code, and any other applicable law and/or the Obligations.

   All costs and expenses incurred by Bank in enforcing its rights under this 
   Note or any mortgage or other lien, endorsement, surety agreement, guarantee 
   relating thereto are the obligations of Maker and are immediately due and 
   payable. Interest shall accrue on such costs and expenses from the date of
   incurrence at the rate specified herein for delinquent Note payments. Each 
   Maker, endorser, surety and guarantor hereby waives presentment, protest, 
   demand, notice of dishonor, and the defense of any statute of limitations.

4. GENERAL. Without affecting the liability of any Maker, endorser, surety, or 
   guarantor, the holder may, without notice, renew or extend the time for 
   payment, accept partial payments, release or impair any collateral security 
   for the payment of this Note or agree to sue any party liable on it.

   Subject to rights afforded by law, Bank may, at any time and for any reason, 
   charge to or off-set against any amount then on deposit in any account 
   (including a savings certificate), whether or not then due, any and all debts
   or liabilities (sole, several, joint, or joint and severable, absolute or 
   contingent, due or not due, liquidated or unliquidated, secured or 
   unsecured) then owed to Bank by depositor or in the case of a multiple-party 
   account, by any party to such multiple-party account, and this agreement 
   shall be construed to be the consent of depositor and any such party for the 
   Bank to make such charge or off-set if consent be required by any person or 
   future law.

   Bank shall not be deemed to have waived any of its rights upon or under this 
   Note, or under any mortgage or other lien, endorsement, surety agreement, or 
   guarantee unless such waivers be in writing and signed by Bank. No delay or 
   omission on the part of Bank in exercising any right shall operate as a 
   waiver of such right or any other right. A waiver on any one occasion shall 
   not be construed as a bar to or waiver of any right on any future occasion. 
   All rights and remedies of Bank on liabilities or the collateral whether 
   evidenced hereby or by any other instrument or papers shall be cumulative and
   may be exercised singularly or concurrently.

   Maker, if more than one, shall be jointly and severally liable hereunder and
   all provisions hereof regarding the liabilities or security of Maker shall 
   apply to any liability or any security of any or all of them. This 
   agreement shall be binding upon the heirs, executors, administrators, 
   assigns or successors of Maker; shall constitute a continuing agreement, 
   applying to all future as well as existing transaction, whether or not of 
   the character contemplated at the date of this Note, and if all 
   transactions between Bank and Maker shall be at any time closed, shall be 
   equally applicable to any new transactions thereafter; shall benefit Bank, 
   its successors, and assigns; and shall so continue in force not 
   withstanding any change in any partnership party hereto, whether such 
   change occurs through death, retirement or otherwise.

   If any party of this Note is a married person, such person or persons 
   hereby separately charges his or her separate estate, including both that 
   now owned and that hereafter acquired, with the payment of this Note.

   This Note shall be construed according to the laws of the State of Nebraska.

   Unless the content otherwise requires, all terms used herein which are 
   defined in the Uniform Commercial Code shall have the meanings therein 
   stated.

   Any provision of this Note which is prohibited or unenforceable in any 
   jurisdiction shall, as to such jurisdiction, be ineffective to the extent 
   of such prohibition or unenforceability without invalidating the remaining 
   provisions hereof or affecting the validity or enforceability of such 
   provision in any other jurisdiction.

                                                                    EXHIBIT A-2

   Each maker specifically consents to multiple renewals or extensions of the
   Obligations. This Note shall be deemed extended through the date of any 
   advance made by Bank after the original maturity hereof; and any such

   hereby waives presentment, protest, demand, notice of dishonor, and the

   Note, or under any mortgage or other lien, endorsement, surety agreement, or 
   guarantee unless such waivers be in writing and signed by Bank. No delay or 
   omission on the part of Bank in exercising any right shall operate as a 
   waiver of such right or any other right. A waiver on any one occasion shall 
   not be construed as a bar to or waiver of any right on any future occasion.

   may be exercised singularly or concurrently.

   Maker, if more than one, shall be jointly and severally liable hereunder 
   and all provisions hereof regarding the liabilities or security of Maker 
   shall apply to any liability or any security of any or all of them. This 
   agreement shall be binding upon the heirs, executors, administrators,

        (including by way of participation) by BANK and any and all renewals,
        extensions for any period, and rearrangements thereof.

REPRESENTATIONS, WARRANTIES, COVENANTS AND AGREEMENTS.

    PLEDGOR represents, warrants, covenants and agrees as follows:

3.  As to any SECURITIES which are stock or other interest in corporations, 
    the SECURITIES are duly authorized, are validly issued and are validly 
    outstanding, are fully paid and are nonassessable, and were not issued in 
    violation of the preemptive rights of any person or entity or of any 
    agreement by which PLEDGOR or any issuer of the SECURITIES is bound. As to 
    any SECURITIES which are interest in partnerships, such interests are valid,
    nonassessable interests in the partnerships indicated.

4.  All information supplied and statements made by PLEDGOR in any financial, 
    credit or accounting statement or application for credit prior to, 
    contemporaneously with or subsequent to the execution of this Security 
    Agreement are and shall be true, correct, complete, valid and genuine.

5.  Except for the security interest of BANK and unless otherwise agreed in 
    writing, PLEDGOR owns (and at the time of transfer or delivery of the 
    COLLATERAL to BANK owned or will own) good and indefeasible title to the 
    COLLATERAL free and clear of any other security interests, liens, adverse 
    claims or options; PLEDGOR has (and at the time of transfer or delivery of 
    the COLLATERAL to BANK had or will have) full right, power and authority 
    to convey, assign, transfer and deliver the COLLATERAL and to grant a 
    security interest in the COLLATERAL to BANK in the manner provided herein 
    and free and clear of any other security interests, liens, adverse claims 
    and options; no security interest or lien has been created by PLEDGOR or 
    is known by PLEDGOR to exist with respect to any COLLATERAL; and, to the 
    best of PLEDGOR's information and belief, no financing statement or other 
    security instrument is on file in any jurisdiction covering any COLLATERAL.

6.  The SECURITIES which evidence interests in corporations were properly 
    issued, drawn, made and/or accepted and are genuine; the issuer, drawer, 
    maker, and/or acceptor thereof has no defenses (including defenses of any 
    party which would be available in an action on a simple contract and the 
    defenses of want or failure of consideration, non-performance of any 
    condition precedent, non-delivery, or delivery for a special purpose), right
    of set off or claims to the securities; PLEDGOR has no knowledge that the 
    signature of the issuer, drawer, maker and/or acceptor is unauthorized; none
    of the SECURITIES has been materially altered; all signatures on each of the
    SECURITIES are genuine or authorized; no defense of any party is good 
    against PLEDGOR; PLEDGOR has no knowledge of any insolvency proceedings 
    instituted with respect to the issuer, maker and/or acceptor of the 
    SECURITIES; PLEDGOR's transfer of the SECURITIES to BANK is effective and 
    rightful; and PLEDGOR knows of no fact which might impair the validity of 
    the SECURITIES.

7.  PLEDGOR agrees to pay prior to any delinquency all taxes, charges, liens 
    and assessments against the COLLATERAL, and upon the failure of PLEDGOR to 
    do so, BANK at its option may pay any of them and shall be the sole judge 
    of the legality or validity thereof and the amount necessary to discharge 
    the same.

8.  PLEDGOR will at all times maintain with BANK COLLATERAL of a character and 
    value satisfactory to BANK. If at any time any of the COLLATERAL shall 
    depreciate in character or value or otherwise be unsatisfactory to BANK, 
    BANK in its discretion may demand such further COLLATERAL or such payment 
    on account of the INDEBTEDNESS as will be satisfactory to BANK.



<PAGE>

9.  BANK shall be deemed to have possession of any of the COLLATERAL in 
    transit to it or set apart by it.

10. PLEDGOR will sign, execute, deliver and file, alone or with BANK, any 
    financing statement, security agreements or other documents or procure any 
    document as may be requested by BANK from time to time to confirm, perfect 
    and preserve the security interest created hereby, and in addition, PLEDGOR
    hereby authorizes BANK to execute and deliver on behalf of PLEDGOR and to 
    file such financing statements, security agreements and other documents 
    without the signature of PLEDGOR. PLEDGOR shall do all such additional and 
    further acts, things, deeds, give such assurances and execute such 
    instruments as BANK requires to vest more completely in and assure to BANK 
    its rights under this Security Agreement. At the option of BANK, a carbon, 
    photographic or other reproduction of this Security Agreement or of a 
    financing statement covering the COLLATERAL shall be sufficient as a 
    financing statement and may be filed as a financing statement.

11. PLEDGOR will transmit to BANK promptly all information that PLEDGOR may 
    have or receive (i) with respect to the COLLATERAL or (ii) with respect to 
    obligors of the COLLATERAL which might in any way affect the value of the 
    COLLATERAL or BANK's rights or remedies with respect thereto.

12. Unless otherwise agreed in writing, PLEDGOR will not pledge, mortgage, 
    otherwise encumber, create or suffer a security interest to exist in, any
    of the COLLATERAL (other than in favor of BANK) or sell, assign or 
    otherwise transfer any of the COLLATERAL to or in favor of anyone other 
    than BANK, and PLEDGOR will not file or permit to be filed any financing 
    statement or other security instrument with respect to the COLLATERAL other 
    than in favor of BANK.

13. PLEDGOR will not adjust, settle or compromise any of the COLLATERAL 
    without the prior written consent of BANK.

14. PLEDGOR agrees to pay to BANK at BANK's banking quarters, all advances, 
    charges, costs and expenses (including reasonable attorneys' fees and 
    legal expenses) incurred by BANK in connection with the transaction which 
    gives rise to this Security Agreement, in connection with confirming, 
    perfecting and preserving the security interest created under this Security
    Agreement, in connection with protecting BANK against the claims or 
    interests of any third person against the COLLATERAL, and in exercising any

    by BANK in the collection of instruments deposited with or purchased by BANK

    to BANK upon demand together with interest thereon from the date of demand 
    at the maximum rate specified in any document evidencing INDEBTEDNESS.

    in Paragraph 1 above and the balance of every deposit account of PLEDGOR 
    with BANK and any other claim of PLEDGOR against BANK, now or hereafter 
    existing, and all money, instruments, securities, documents, chattel 
    paper, credits, claims, demands and any other property, rights and 
    interests of PLEDGOR which are now or at any time shall come into the 
    possession or custody or under the control of the BANK, for any purpose,
    and shall include the proceeds of any thereof. 

RIGHTS AND REMEDIES.

    PLEDGOR and in PLEDGOR's name, place and stead with full power of

    respect to all or any of the COLLATERAL (regardless of whether any of

        covenants or agreements contained in said instruments, or any one of
        them. BANK shall be entitled to foreclose said rights and liens and 
        have the properties covered by said instruments sold, in whole or in

        BANK may determine; all without notice and without liability except
        to account for property actually received by BANK; and

    (h) demand, sue for, collect, receive, receipt for, compound and give 
        acquittance for any and all amounts, money or property at any time 
        payable or receivable on account of or in exchange for, any of the
        COLLATERAL,

    provided, however, BANK shall be under no obligation or duty to exercise 
    any of the powers hereby conferred upon it and shall be without liability 
    for any act or failure to act in connection with the collection of, or the
    preservation of any rights under, any COLLATERAL.

17. At the option of BANK and without necessity of demand or notice, all or 
    any part of the INDEBTEDNESS shall immediately become due and payable
    irrespective of any agreed maturity or period of grace (provided, however,
    such consideration that constitutes interest under applicable law may 
    never include more than the maximum amount allowed by applicable law, and
    excess interest, if any, shall be automatically cancelled as of the date 
    of such acceleration and if theretofore paid, shall be credited on the
    INDEBTEDNESS) and/or any obligation of BANK for further financial 
    accommodation shall terminate upon the happening of any of the following 
    events:

    (a) any breach of this Security Agreement or any other agreement between 
        BANK and PLEDGOR or any other party primarily or secondarily liable 
        for all or any part of the INDEBTEDNESS (herein collectively and 
        individually called "OTHER LIABLE PARTY");

<PAGE>

    (b) default in the payment of any of the INDEBTEDNESS when due;

    (c) any deterioration, impairment or decline in character or value of any 
        part of the COLLATERAL or any other collateral subject to a security
        interest in favor of BANK as security for the INDEBTEDNESS (whether
        actual or reasonably anticipated) that causes the COLLATERAL or any
        such other COLLATERAL in the judgment of BANK to become unsatisfactory
        as to character or value;

    (d) the entry of a judgment, issuance of an injunction or order of 
        attachment, or any other process against PLEDGOR, or any of the
        COLLATERAL, or OTHER LIABLE PARTY;

    (e) the application for the appointment of, or the appointment of, a 
        receiver, trustee, liquidator, conservator, rehabilitator, or similar
        individual, officer or committee of, or for any property of, PLEDGOR or
        OTHER LIABLE PARTY;

    (f) the death, incapacity, insolvency, dissolution, commission of an act 
        of bankruptcy, assignment for the benefit of creditors, calling of a
        meeting of any creditors, appointment of a committee of any creditors
        or a liquidating agent, offering to or receiving from any creditors a
        composition or extension of any of the indebtedness of any of them,
        making a bulk transfer, granting a security interest in any property, 
        the whole or partial suspension, discontinuance or liquidation of 
        usual business or failure in business of or by PLEDGOR or OTHER LIABLE
        PARTY, including the imminent or threatened occurrence of any of the
        foregoing events;

    (g) the commencement of any proceeding, suit or action under any 
        provisions of the Bankruptcy Code, as amended, or any similar statute,
        for adjudication as a bankrupt, reorganization, composition, 
        extension, arrangement, wage earner's plan, receivership, liquidation
        or dissolution by or against PLEDGOR or OTHER LIABLE PARTY;

    (h) the admission in writing by PLEDGOR or OTHER LIABLE PARTY of 
        inability to pay its debts as they become due;

    (i) failure of the PLEDGOR, OTHER LIABLE PARTY or the COLLATERAL to 
        comply with Regulations U or X of the Board of Governors of the 
        Federal Reserve System, as amended;

    (j) failure by PLEDGOR or OTHER LIABLE PARTY, after demand, to furnish any
        financial information to BANK or to permit BANK to inspect books or
        records of account, making any misrepresentation to BANK for the 
        purpose of obtaining credit, failure to pay when due any obligations,
        failure to pay any tax or failure to withhold, collect or remit any 
        tax or tax deficiency when assessed or due;

    (k) failure by PLEDGOR, upon demand from BANK to furnish such further 
        COLLATERAL or make such payment on account of the INDEBTEDNESS as
        will be satisfactory to BANK; or

    (l) if in the reasonable exercise of its judgment, BANK determines that 
        the financial responsibility of PLEDGOR or OTHER LIABLE PARTY has
        become otherwise unsatisfactory.

18. If all or any part of the INDEBTEDNESS shall become due and payable as 
    specified in paragraph 17, BANK may then, or at any time thereafter, apply,
    set-off, collect, sell in one or more sales, lease, or otherwise dispose of,
    any or all of the COLLATERAL in its then condition or following any 
    commercially reasonable preparation or processing, in such order as BANK may
    elect, and any such sale may be made either at public or private sale at its
    place of business or elsewhere, or at any brokers' board or securities 
    exchange, either for cash or upon credit or for future delivery, at such 
    price as BANK may deem fair, and BANK may be the purchaser of any or all 
    COLLATERAL so sold and may hold the same thereafter in its own right free 
    from any claim of PLEDGOR or right of redemption. No such purchase or 
    holding by BANK shall be deemed a retention by BANK in satisfaction of the
    INDEBTEDNESS. All demands, notices and advertisements, and the presentment
    of property at sale are hereby waived. If, notwithstanding the foregoing 
    provisions, any applicable provision of the Uniform Commercial Code or other
    law requires BANK to give reasonable notice of any such sale or disposition 
    or other action, five days' prior written notice shall constitute reasonable
    notice. BANK may require PLEDGOR to assemble the COLLATERAL and make it 
    available to BANK at a place designated by BANK in Douglas County, Nebraska 
    which is reasonably convenient to BANK and PLEDGOR. Any sale hereunder may
    be conducted by an auctioneer or any officer or agent of BANK.

19. Prior to all or any part of the INDEBTEDNESS becoming due and payable as 
    specified in paragraph 17, all cash sums paid to and received by BANK
    on account of the COLLATERAL shall be promptly applied by BANK on the 
    INDEBTEDNESS whether or not such INDEBTEDNESS shall have by its terms 
    matured, such application to be made first to interest and then to 
    principal or exclusively to principal as BANK may determine; provided,
    however, BANK need not apply or give credit for any item included in
    such sums until BANK has received final payment thereof at its banking
    quarters or solvent credits accepted as such by BANK. After all or any
    part of the INDEBTEDNESS becomes due and payable as specified in paragraph
    17, the proceeds of any sale or other disposition of the COLLATERAL and 
    all sums received or collected by BANK from or on account of the 
    COLLATERAL the shall be applied by BANK in the manner set forth in 
    Section 9.504 of the Nebraska Uniform Commercial Code as presently in
    effect. PLEDGOR shall remain liable to BANK for any INDEBTEDNESS, 
    advances, costs, charges and expenses, together with interest thereon
    remaining unpaid and shall pay the same immediately to BANK at BANK's 
    banking quarters.

20. BANK shall be under no duty whatsoever to make or give any presentment,
    demand for performance, notice of nonperformance, protest, notice of 
    protest, notice of dishonor, or other notice or demand in connection with
    any COLLATERAL or the INDEBTEDNESS, or to take any steps necessary to
    preserve any rights against prior parties. BANK shall not be liable for 
    failure to collect or realize upon any or all of the INDEBTEDNESS or 
    COLLATERAL, or for any delay in so doing, nor shall BANK be under any duty
    to take any action whatsoever with regard thereto. BANK shall use
    reasonable care in the custody and preservation of any COLLATERAL in its
    possession but need not take any steps to keep the COLLATERAL 
    identifiable. BANK shall have no duty to comply with any recording, 
    filing, or other legal requirements necessary to establish or maintain the
    validity, priority or enforceability of, or BANK's rights in or to, any 
    of the COLLATERAL.

21. PLEDGOR waives any right to require BANK to proceed against any person, 
    exhaust any COLLATERAL or pursue any other remedy in BANK's power; waives 
    any and all notice of acceptance of this Security Agreement or of 
    creation, modification, renewal or extension of any period of any of the 
    INDEBTEDNESS from time to time; and waives any defense arising by reason of
    any disability or other defense of any OTHER LIABLE PARTY, or by reason of
    the cessation from any cause whatsoever of the liability of any OTHER 
    LIABLE PARTY. All dealings between PLEDGOR and BANK, whether or not 
    resulting in the creation of INDEBTEDNESS, shall conclusively be presumed
    to have been had or consummated in reliance upon this Security Agreement.
    Until all the INDEBTEDNESS shall have been paid in full, PLEDGOR shall 
    have no right to subrogation, and PLEDGOR waives any right to enforce any
    remedy which BANK now has or may hereafter have against PLEDGOR or OTHER
    LIABLE PARTY and waives any benefit of and any right to participate in 
    any COLLATERAL or security whatsoever now or hereafter held by BANK.
    PLEDGOR authorizes BANK, without notice or demand and without any 
    reservation of rights against PLEDGOR and without affecting PLEDGOR's 
    liability hereunder or on the INDEBTEDNESS, from time to time to (a) 
    renew, extend for any period, accelerate, modify, compromise, settle or
    release the obligation of PLEDGOR or any OTHER LIABLE PARTY with respect
    to any or all of the INDEBTEDNESS or COLLATERAL, (b) take and hold any 
    other property as collateral, other than the COLLATERAL, for the payment
    of any or all of the INDEBTEDNESS, and exchange, enforce, waive and 
    release any or all of the COLLATERAL or such other property; (c) apply the
    COLLATERAL or such other property and direct the order or manner of sale
    thereof as BANK in its discretion may determine; and (d) release or 
    substitute PLEDGOR or any OTHER LIABLE PARTY.

22. BANK may transfer any or all of the INDEBTEDNESS, and upon any such 
    transfer BANK may transfer any or all of the COLLATERAL and shall be fully
    discharged thereafter from all liability with respect to the COLLATERAL
    so transferred, and the transferee shall be vested with all rights, powers
    and remedies of BANK hereunder with respect to COLLATERAL so transferred; 
    but with respect to any COLLATERAL not so transferred BANK shall retain 
    all rights, powers and remedies hereby given. BANK may at any time deliver
    any or all of the COLLATERAL to PLEDGOR whose receipt shall be a complete
    and full acquittance for the COLLATERAL so delivered, and BANK shall 
    thereafter be discharged from any liability therefor.

23. The execution and delivery of this Security Agreement in no manner shall
    impair or affect any other security (by endorsement or otherwise) for the
    payment of the INDEBTEDNESS. No security taken hereafter as security for
    payment of the INDEBTEDNESS shall impair in any manner or affect this
    Security Agreement. All such present and future additional security is
    to be considered as cumulative security.

<PAGE>

24. This is a continuing agreement and the conveyance hereunder shall remain 
    in full force and effect and all the rights, powers and remedies of BANK 
    hereunder shall continue to exist until the INDEBTEDNESS is paid in full
    as the same becomes due and payable; until BANK has no further 
    obligation to advance monies to PLEDGOR, or any OTHER LIABLE PARTY; and 
    until BANK, upon request of PLEDGOR has executed a written termination 
    statement, reassigned to PLEDGOR without recourse, the COLLATERAL and all 
    rights and liens conveyed hereby and returned possession of the COLLATERAL
    to PLEDGOR. Furthermore, it is contemplated by the parties hereto that 
    there may be times when no INDEBTEDNESS is owing; but notwithstanding such
    occurrence, this Security Agreement shall remain valid and shall be in 
    full force and effect as to subsequent INDEBTEDNESS provided that BANK has
    not executed a written termination statement and returned possession of 
    the COLLATERAL to PLEDGOR. Otherwise this Security Agreement shall 
    continue irrespective of the fact that the liability of OTHER LIABLE 
    PARTY may have ceased, and notwithstanding the death or incapacity of
    PLEDGOR or the death, incapacity or bankruptcy of OTHER LIABLE PARTY, or
    any other event or proceeding affecting PLEDGOR and/or OTHER LIABLE PARTY.

25. The rights, powers and remedies of BANK hereunder shall be in addition to 
    all rights, powers and remedies given by statute or rule of law and are
    cumulative. The exercise of any one or more of the rights, powers and
    remedies provided herein shall not be construed as a waiver of any other
    rights, powers and remedies of BANK. Furthermore, regardless of whether 
    or not the Uniform Commercial Code is in effect in the jurisdiction where 
    such rights, powers and remedies are asserted, BANK shall have the rights, 
    powers and remedies of a secured party under the Nebraska Uniform 
    Commercial Code, as amended. BANK may exercise its bankers' lien or right 
    of set-off with respect to the INDEBTEDNESS in the same manner as if the 
    INDEBTEDNESS were unsecured. Time shall be of the essence for the 
    performance of any act under this Security Agreement or the INDEBTEDNESS by
    PLEDGOR or OTHER LIABLE PARTY, but neither BANK's acceptance of partial or
    delinquent payments nor any forbearance, failure or delay by BANK in 
    exercising any right, power or remedy shall be deemed a waiver of any
    obligation of PLEDGOR or OTHER LIABLE PARTY or of any right, power or
    remedy of BANK or preclude any other or further exercise thereof; and
    no single or partial exercise of any right, power or remedy shall preclude
    any other or further exercise thereof, or the exercise of any other right,
    power or remedy.

26. BANK may remedy any default and may waive any default without waiving the 
    default remedied or waiving any prior or subsequent default.

GENERAL.
27. The term "PLEDGOR", as used throughout this Security Agreement shall 
    (regardless of use of the singular form) mean PLEDGOR individually and/or
    collectively and shall include the respective successors, legal 
    representatives, heirs and assigns of PLEDGOR. The obligations and 
    agreements of PLEDGOR hereunder are joint and several. The PLEDGOR is and
    shall be deemed to be a "Debtor" within the meaning of that term as 
    defined in the Uniform Commercial Code.

28. Neither this Security Agreement nor the exercise by BANK of (or the 
    failure to so exercise) any right, power or remedy conferred herein or by 
    law shall be construed as relieving any person liable on the INDEBTEDNESS
    from full liability on the INDEBTEDNESS and for any deficiency thereon.

29. Any notice or demand to PLEDGOR under this Security Agreement or in 
    connection with the Security Agreement may be given and shall conclusively
    be deemed and considered to have been given and received upon the deposit
    thereof, in writing, duly stamped and addressed to PLEDGOR at the address
    of PLEDGOR appearing on the records of the BANK, in the U.S. Mail, but 
    actual notice, however given or received, shall always be effective.

30. This Security Agreement has been made in and the conveyance, assignment, 
    transfer and delivery has been made in and the security interest granted
    hereby is granted in and each shall be governed by the laws of the State
    of Nebraska in all respects, including matters of construction, validity,
    enforcement and performance. This Security Agreement may not be amended
    (nor may any of its terms be waived) except in writing duly signed by an
    authorized officer of BANK and by PLEDGOR. Except as the context may 
    otherwise require, any term used herein that is defined in the
    Nebraska Uniform Commercial Code shall have the meaning given therein.
    If any provision of this Security Agreement is rendered or declared
    illegal or unenforceable by reason of any existing or subsequently
    enacted legislation or by a judicial decision which shall have become
    final, PLEDGOR and BANK shall promptly meet and negotiate substitute
    provisions for those rendered illegal or unenforceable, but all of the
    remaining provisions shall remain in full force and effect.

31. The covenants, representations, warranties and agreements herein set forth
    shall be binding upon PLEDGOR and shall inure to the benefit of BANK, its
    successors and assigns.

33. BANK MAY ENFORCE ITS RIGHTS HEREUNDER WITHOUT PRIOR JUDICIAL PROCESS OR
    JUDICIAL HEARING, AND PLEDGOR EXPRESSLY WAIVES, RENOUNCES AND KNOWINGLY
    RELINQUISHES ANY AND ALL LEGAL RIGHTS WHICH MIGHT OTHERWISE REQUIRE BANK
    TO ENFORCE ITS RIGHTS BY JUDICIAL PROCESS. IN SO PROVIDING FOR NONJUDICIAL
    REMEDIES, PLEDGOR RECOGNIZES AND CONCEDES THAT SUCH REMEDIES ARE 
    CONSISTENT WITH THE USAGE OF THE TRADE, ARE RESPONSIVE TO COMMERCIAL 
    NECESSITY, AND ARE THE RESULT OF BARGAIN AT ARM'S LENGTH. NOTHING HEREIN
    IS INTENDED TO PREVENT BANK OR PLEDGOR FROM RESORTING TO JUDICIAL PROCESS
    AT EITHER PARTY'S OPTION.

    IN WITNESS WHEREOF the PLEDGOR has executed this Agreement this the 24th 
day of April, 1992 in Omaha, Nebraska.

REPRESENTATIONS, WARRANTIES, COVENANTS AND AGREEMENTS.

   PLEDGOR represents, warrants, covenants and agrees as follows:


3. As to any SECURITIES which are stock or other interest in corporations, the
   SECURITIES are duly authorized, are validly issued and are validly 
   outstanding, are fully paid and are nonassessable, and were not issued in
   violation of the preemptive rights of any person or entity or of any
   agreement by which PLEDGOR or any issuer of the SECURITIES is bound. As to
   any SECURITIES which are interest in partnerships, such interests are 
   valid, nonassessable interests in the partnerships indicated.

4. All information supplied and statements made by PLEDGOR in any financial, 
   credit or accounting statement or application for credit prior to, 
   contemporaneously with or subsequent to the execution of this Security 
   Agreement are and shall be true, correct, complete, valid and genuine.

5. Except for the security interest of BANK and unless otherwise agreed in 
   writing, PLEDGOR owns (and at the time of transfer or delivery of the
   COLLATERAL to BANK owned or will own) good and indefeasible title to the
   COLLATERAL free and clear of any other security interests, liens, adverse
   claims or options; PLEDGOR has (and at the time of transfer or delivery of
   the COLLATERAL to BANK had or will have) full right, power and authority to
   convey, assign, transfer and deliver the COLLATERAL and to grant a security
   interest in the COLLATERAL to BANK in the manner provided herein and free
   and clear of any other security interests, liens, adverse claims and 
   options; no security interest or lien has been created by PLEDGOR or is 
   known by PLEDGOR to exist with respect to any COLLATERAL; and, to the best 
   of PLEDGOR's information and belief, no financing statement or other 
   security instrument is on file in any jurisdiction covering any COLLATERAL.

6. The SECURITIES which evidence interests in corporations were properly 
   issued, drawn, made and/or accepted and are genuine; the issuer, drawer,
   maker, and/or acceptor thereof has no defenses (including defenses of any
   party which would be available in an action on a simple contract and the
   defenses of want or failure of consideration, non-performance of any 
   condition precedent, non-delivery, or delivery for a special purpose), 
   right of set off or claims to the securities; PLEDGOR has no knowledge that
   the signature of the issuer, drawer, maker and/or acceptor is unauthorized;
   none of the SECURITIES has been materially altered; all signatures on each
   of the SECURITIES are genuine or authorized; no defense of any party is 
   good against PLEDGOR; PLEDGOR has no knowledge or any insolvency 
   proceedings instituted with respect to the issuer, maker and/or acceptor
   of the SECURITIES; PLEDGOR's transfer of the SECURITIES to BANK is 
   effective and rightful; and PLEDGOR knows of no fact which might impair the
   validity of the SECURITIES.

7. PLEDGOR agrees to pay prior to any deliquency all taxes, charges, liens and
   assessments against the COLLATERAL, and upon the failure of PLEDGOR to do 
   so, BANK at its option may pay any of them and shall be the sole judge of 
   the legality or validity thereof and the amount necessary to discharge the
   same.

8. PLEDGOR will at all times maintain with BANK COLLATERAL of a character 
   and value satisfactory to BANK. If at any time any of the COLLATERAL shall
   depreciate in character or value or otherwise be unsatisfactory to BANK, 
   BANK in its discretion may demand such further COLLATERAL or such payment 
   on account of the INDEBTEDNESS as will be satisfactory to BANK.

<PAGE>

 9. BANK shall be deemed to have possession any of the COLLATERAL in transit 
    to it or set apart.

10. PLEDGOR will sign, execute, deliver and file, alone or with BANK, any 
    financing statement, security agreements or other documents or procure any
    document as may be requested by BANK from time to time to confirm, perfect
    and preserve the security interest created hereby, and in addition, 
    PLEDGOR hereby authorizes BANK to execute and deliver on behalf of PLEDGOR
    and to file such financing statements, security agreements and other 
    documents without the signature of PLEDGOR. PLEDGOR shall do all such 
    additional and further acts, things, deeds, give such assurances and 
    execute such instruments as BANK requires to vest more completely in and 
    assure to BANK its rights under this Security Agreement. At the option of
    BANK, a carbon, photographic or other reproduction of this Security 
    Agreement or of a financing statement covering the COLLATERAL shall be
    sufficient as a financing statement and may be filed as a financing 
    statement.  

11. PLEDGOR will transmit to BANK promptly all information that PLEDGOR may 
    have or receive (i) with respect to the COLLATERAL or (ii) with respect to
    obligors of the COLLATERAL which might in any way affect the value of the
    COLLATERAL or BANK's rights or remedies with respect thereto.

12. Unless otherwise agreed in writing, PLEDGOR will not pledge, mortgage, 
    otherwise encumber, create or suffer a security interest to exist in, any
    of the COLLATERAL (other than in favor of BANK) or sell, assign or 
    otherwise transfer any of the COLLATERAL, to or in favor of anyone other
    than BANK, and PLEDGOR will not file or permit to be filed any financing
    statement or other security instrument with respect to the COLLATERAL 
    other than in favor of BANK.

13. PLEDGOR will not adjust, settle or compromise any of the COLLATERAL 
    without the prior written consent of BANK.

14. PLEDGOR agrees to pay to BANK at BANK's banking quarters, all advances, 
    charges, costs and expenses (including reasonable attorneys' fees and 
    legal expenses) incurred by BANK in connection with the transaction 
    which gives rise to this Security Agreement, in connection with 
    confirming, perfecting and preserving the security interest created 
    under this Security Agreement, in connection with protecting BANK 
    against the claims or interests of any third person against the 
    COLLATERAL, and in exercising any right, power or remedy conferred to 
    this Security Agreement or by law (including, but not limited to, 
    attorney's fees and legal expenses incurred by BANK in the collection of 
    instruments deposited with or purchased by BANK and amounts incurred in 
    connection with the operation, maintenance of foreclosure of any or all 
    of the COLLATERAL). The amount of all such advances, charges, costs and 
    expenses shall be due and payable by PLEDGOR to BANK upon demand 
    together with interest thereon from the date of demand at the maximum 
    rate specified in any document evidencing INDEBTEDNESS.

15. The term "COLLATERAL" shall include the property described or referred to 
    in Paragraph 1 above and the balance of every deposit account of PLEDGOR 
    with BANK and any other claim of PLEDGOR against BANK, now or hereafter
    existing, and all money, instruments, securities, documents, chattel 
    paper, credits, claims, demands and any other property, rights and 
    interests of PLEDGOR which are now or at any time shall come into the
    possession or custody or under the control of the BANK, for any purpose,
    and shall include the proceeds of any thereof.

    never include more than the maximum amount allowed by applicable law, and
    excess interest, if any, shall be automatically cancelled as of the date 
    of such acceleration and if theretofore paid, shall be credited on the

    events:

    (c) any deterioration, impairment or decline in character or value of any 
        part of the COLLATERAL or any other collateral subject to a security

        such other COLLATERAL in the judgement of BANK to become unsatisfactory
        as to character or value;

        OTHER LIABLE PARTY;

    (f) the death, incapacity, insolvency, dissolution, commission of an act 
        of bankruptcy, assignment for the benefit of creditors, calling of a
        meeting of any creditors, appointment of a committee of any creditors

    (l) if in the reasonable exercise of its judgement, BANK determines that 
        the financial responsibility of PLEDGOR or OTHER LIABLE PARTY has
        become otherwise unsatisfactory.

18. If all or any part of the INDEBTEDNESS shall become due and payable as 
    specified in paragraph 17, BANK may then, or at any time thereafter, apply,
    set-off, collect, sell in one or more sales, lease, or otherwise dispose of,
    any or all of the COLLATERAL, in its then condition or following any 
    commercially reasonable preparation or processing, in such order as BANK may
    elect, and any such sale may be made either at public or private sale at its
    place of business or elsewhere, or at any brokers' board or securities 
    exchange, either for cash or upon credit or for future delivery, at such 
    price as BANK may deem fair, and BANK may be the purchaser of any or all 
    COLLATERAL so sold and may hold the same thereafter in its own right free 
    from any claim of PLEDGOR or right of redemption. No such purchase or 
    holding by BANK shall be deemed a retention by BANK in satisfaction of the
    INDEBTEDNESS. All demands, notices and advertisements, and the presentment
    of property at sale are hereby waived. If, notwithstanding the foregoing 
    provisions, any applicable provision of the Uniform Commercial Code or other
    law requires BANK to give reasonable notice of any such sale or disposition 
    or other action, five days' prior written notice shall constitute reasonable
    notice. BANK may require PLEDGOR to assemble the COLLATERAL and make it 
    available to BANK at a place designated by BANK in Douglas County, Nebraska 
    which is reasonably convenient to BANK and PLEDGOR. Any sale hereunder may
    be conducted by an auctioneer or any officer or agent of BANK.

19. Prior to all or any part of the INDEBTEDNESS becoming due and payable as 
    specified in paragraph 17, all cash sums paid to and received by BANK
    on account of the COLLATERAL shall be promptly applied by BANK on the 
    INDEBTEDNESS whether or not such INDEBTEDNESS shall have by its terms 
    matured, such application to be made first to interest and then to 
    principal or exclusively to principal as BANK may determine; provided,
    however, BANK need not apply or give credit for any item included in
    such sums until BANK has received final payment thereof at its banking
    quarters or solvent credits accepted as such by BANK. After all or any
    part of the INDEBTEDNESS becomes due and payable as specified in paragraph
    17, the proceeds of any sale or other disposition of the COLLATERAL and 
    all sums received or collected by BANK from or on account of the 
    COLLATERAL the shall be applied by BANK in the manner set forth in 
    Section 9.504 of the Nebraska Uniform Commercial Code as presently in
    effect. PLEDGOR shall remain liable to BANK for any INDEBTEDNESS, 
    advances, costs, charges and expenses, together with interest thereon
    remaining unpaid and shall pay the same immediately to BANK at BANK's 
    banking quarters.

20. BANK shall be under no duty whatsoever to make or give any presentment,
    demand for performance, notice of nonperformance, protest, notice of 
    protest, notice of dishonor, or other notice or demand in connection with
    any COLLATERAL or the INDEBTEDNESS, or to take any steps necessary to
    preserve any rights against prior parties. BANK shall not be liable for 
    failure to collect or realize upon any or all of the INDEBTEDNESS or 
    COLLATERAL, or for any delay in so doing, nor shall BANK be under any duty
    to take any action whatsoever with regard thereto. BANK shall use
    reasonable care in the custody and preservation of any COLLATERAL in its
    possession but need not take any steps to keep the COLLATERAL 
    identifiable. BANK shall have no duty to comply with any recording, 
    filing, or other legal requirements necessary to establish or maintain the
    validity, priority or enforceability of, or BANK's rights in or to, any 
    of the COLLATERAL.

21. PLEDGOR waives any right to require BANK to proceed against any person, 
    exhaust any COLLATERAL or pursue any other remedy in BANK's power; waives 
    any and all notice of acceptance of this Security Agreement or of 
    creation, modification, renewal or extension for any period of any of the 
    INDEBTEDNESS from time to time; and waives any defense arising by reason of
    any disability or other defense of any OTHER LIABLE PARTY, or by reason of
    the cessation from any cause whatsoever of the liability of any OTHER 
    LIABLE PARTY. All dealings between PLEDGOR and BANK, whether or not 
    resulting in the creation of INDEBTEDNESS, shall conclusively be presumed
    to have been had or consummated in reliance upon this Security Agreement.
    Until all the INDEBTEDNESS shall have been paid in full, PLEDGOR shall 
    have no right to subrogation, and PLEDGOR waives any right to enforce any
    remedy which BANK now has or may hereafter have against PLEDGOR or OTHER
    LIABLE PARTY and waives any benefit of and any right to participate in 
    any COLLATERAL or security whatsoever now or hereafter held by BANK.
    PLEDGOR authorizes BANK, without notice or demand and without any 
    reservation of rights against PLEDGOR and without affecting PLEDGOR's 
    liability hereunder or on the INDEBTEDNESS, from time to time to (a) 
    renew, extend for any period, accelerate, modify, compromise, settle or
    release the obligation of PLEDGOR or any OTHER LIABLE PARTY with respect
    to any or all of the INDEBTEDNESS or COLLATERAL, (b) take and hold any 
    other property as collateral, other than the COLLATERAL, for the payment
    of any or all of the INDEBTEDNESS, and exchange, enforce, waive and 
    release any or all of the COLLATERAL or such other property; (c) apply the
    COLLATERAL or such other property and direct the order or manner of sale
    thereof as BANK in its discretion may determine; and (d) release or 
    substitute PLEDGOR or any OTHER LIABLE PARTY.

22. BANK may transfer any or all of the INDEBTEDNESS, and upon any such 
    transfer BANK may transfer any or all of the COLLATERAL and shall be fully
    discharged thereafter from all liability with respect to the COLLATERAL
    so transferred, and the transferee shall be vested with all rights, powers
    and remedies of BANK hereunder with respect to COLLATERAL so transferred; 
    but with respect to any COLLATERAL not so transferred BANK shall retain 
    all rights, powers and remedies hereby given. BANK may at any time deliver
    any or all of the COLLATERAL to PLEDGOR whose receipt shall be a complete
    and full acquittance for the COLLATERAL so delivered, and BANK shall 
    thereafter be discharged from any liability therefor.

23. The execution and delivery of this Security Agreement in no manner shall
    impair or affect any other security (by endorsement or otherwise) for the
    payment of the INDEBTEDNESS. No security taken hereafter as security for
    payment of the INDEBTEDNESS shall impair in any manner or affect this
    Security Agreement. All such present and future additional security is
    to be considered as cumulative security.

<PAGE>

24. This is a continuing agreement and the conveyance hereunder shall remain 
    in full force and effect and all the rights, powers and remedies of BANK 
    hereunder shall continue to exist until the INDEBTEDNESS is paid in full
    as the same becomes due and payable; until BANK has no further 
    obligation to advance monies to PLEDGOR, or any OTHER LIABLE PARTY; and 
    until BANK, upon request of PLEDGOR has executed a written termination 
    statement, reassigned to PLEDGOR without recourse, the COLLATERAL and all 
    rights and liens conveyed hereby and returned possession of the COLLATERAL
    to PLEDGOR. Furthermore, it is contemplated by the parties hereto that 
    there may be times when no INDEBTEDNESS is owing; but notwithstanding such
    occurrence, this Security Agreement shall remain valid and shall be in 
    full force and effect as to subsequent INDEBTEDNESS provided that BANK has
    not executed a written termination statement and returned possession of 
    the COLLATERAL to PLEDGOR. Otherwise this Security Agreement shall 
    continue irrespective of the fact that the liability of OTHER LIABLE 
    PARTY may have ceased, and notwithstanding the death or incapacity of
    PLEDGOR or the death, incapacity or bankruptcy of OTHER LIABLE PARTY, or
    any other event or proceeding affecting PLEDGOR and/or OTHER LIABLE PARTY.

25. The rights, powers and remedies of BANK hereunder shall be in addition to 
    all rights, powers and remedies given by statute or rule of law and are
    cumulative. The exercise of any one or more of the rights, powers and
    remedies provided herein shall not be construed as a waiver of any other
    rights, powers and remedies of BANK. Furthermore, regardless of whether 
    or not the Uniform Commercial Code is in effect in the jurisdiction where 
    such rights, powers and remedies are asserted, BANK shall have the rights, 
    powers and remedies of a secured party under the Nebraska Uniform 
    Commercial Code, as amended. BANK may exercise its bankers' lien or right 
    of set-off with respect to the INDEBTEDNESS in the same manner as if the 
    INDEBTEDNESS were unsecured. Time shall be of the essence for the 
    performance of any act under this Security Agreement or the INDEBTEDNESS by
    PLEDGOR or OTHER LIABLE PARTY, but neither BANK's acceptance of partial or
    delinquent payments nor any forbearance, failure or delay by BANK in 
    exercising any right, power or remedy shall be deemed a waiver of any
    obligation of PLEDGOR or OTHER LIABLE PARTY or of any right, power or
    remedy of BANK or preclude any other or further exercise thereof; and
    no single or partial exercise of any right, power or remedy shall preclude
    any other or further exercise thereof, or the exercise of any other right,
    power or remedy.

26. BANK may remedy any default and may waive any default without waiving the 
    default remedied or waiving any prior or subsequent default.

GENERAL.
27. The term "PLEDGOR", as used throughout this Security Agreement shall 
    (regardless of use of the singular form) mean PLEDGOR individually and/or
    collectively and shall include the respective successors, legal 
    representatives, heirs and assigns of PLEDGOR. The obligations and 
    agreements of PLEDGOR hereunder are joint and several. The PLEDGOR is and
    shall be deemed to be a "Debtor" within the meaning of that term as 
    defined in the Uniform Commercial Code.

28. Neither this Security Agreement nor the exercise by BANK of (or the 
    failure to so exercise) any right, power or remedy conferred herein or by 
    law shall be construed as relieving any person liable on the INDEBTEDNESS
    from full liability on the INDEBTEDNESS and for any deficiency thereon.

29. Any notice or demand to PLEDGOR under this Security Agreement or in 
    connection with the Security Agreement may be given and shall conclusively
    be deemed and considered to have been given and received upon the deposit
    thereof, in writing, duly stamped and addressed to PLEDGOR at the address
    of PLEDGOR appearing on the records of the BANK, in the U.S. Mail, but 
    actual notice, however given or received, shall always be effective.

30. This Security Agreement has been made in and the conveyance, assignment, 
    transfer and delivery has been made in and the security interest granted
    hereby is granted in and each shall be governed by the laws of the State
    of Nebraska in all respects, including matters of construction, validity,
    enforcement and performance. This Security Agreement may not be amended
    (nor may any of its terms be waived) except in writing duly signed by an
    authorized officer of BANK and by PLEDGOR. Except as the context may 
    otherwise require, any term used herein that is defined in the
    Nebraska Uniform Commercial Code shall have the meaning given therein.
    If any provision of this Security Agreement is rendered or declared
    illegal or unenforceable by reason of any existing or subsequently
    enacted legislation or by a judicial decision which shall have become
    final, PLEDGOR and BANK shall promptly meet and negotiate substitute
    provisions for those rendered illegal or unenforceable, but all of the
    remaining provisions shall remain in full force and effect.

31. The covenants, representations, warranties and agreements herein set forth
    shall be binding upon PLEDGOR and shall inure to the benefit of BANK, its
    successors and assigns.

33. BANK MAY ENFORCE ITS RIGHTS HEREUNDER WITHOUT PRIOR JUDICIAL PROCESS OR
    JUDICIAL HEARING, AND PLEDGOR EXPRESSLY WAIVES, RENOUNCES AND KNOWINGLY
    RELINQUISHES ANY AND ALL LEGAL RIGHTS WHICH MIGHT OTHERWISE REQUIRE BANK
    TO ENFORCE ITS RIGHTS BY JUDICIAL PROCESS. IN SO PROVIDING FOR NONJUDICIAL
    REMEDIES, PLEDGOR RECOGNIZES AND CONCEDES THAT SUCH REMEDIES ARE 
    CONSISTENT WITH THE USAGE OF THE TRADE, ARE RESPONSIVE TO COMMERCIAL 
    NECESSITY, AND ARE THE RESULT OF BARGAIN AT ARM'S LENGTH. NOTHING HEREIN
    IS INTENDED TO PREVENT BANK OR PLEDGOR FROM RESORTING TO JUDICIAL PROCESS
    AT EITHER PARTY'S OPTION.

    IN WITNESS WHEREOF the PLEDGOR has executed this Agreement this the 24th 
day of April, 1992 in Omaha, Nebraska.

A. FOR VALUE RECEIVED the undersigned hereby assign, transfer and 
set over to    First National Bank of Omaha, Commercial Loan Dept.,
           -----------------------------------------------------------
   One First National Center     of     Omaha, NE 68102
- --------------------------------    ----------------------------------
its successors and assigns, (herein called the "Assignee") 
Policy No.       00551778         issued by the   Lincoln Benefit 
           ---------------------                ----------------------
  Life Company, 134 S. 13 St., Lincoln, NE 68508
- ----------------------------------------------------------------------
(herein called the "Insurer") and any supplementary contracts issued in
connection therewith (said policy and contracts being herein called the
"Policy"), upon the life of               John Joe Ricketts
                             ------------------------------------------
of    TransTerra Co.         and all claims, options, privileges, rights, 
   -------------------------
title and interest therein and thereunder (except as provided in Paragraph C 
hereof), subject to all the terms and conditions of the Policy and to all 
superior liens, if any, which the Insurer may have against the Policy. The 
undersigned by this instrument jointly and severally agree and the Assignee 
by the acceptance of this assignment agrees to the conditions and provisions 
herein set forth.

B. It is expressly agreed that, without detracting from the generality of the 
foregoing, the following specific rights are included in this assignment 
and pass by virtue hereof:

   1. The sole right to collect from the Insurer the net proceeds of the 
      Policy when it becomes a claim by death or maturity;

   2. The sole right to surrender the Policy and receive the surrender value 
      thereof at any time provided by the terms of the Policy and at such 
      other times as the Insurer may allow;

   3. The sole right to obtain one or more loans or advances on the Policy, 
      either from the Insurer or, at any time, from other persons, and to 
      pledge or assign the Policy as security for such loans or advances;

   4. The sole right to collect and receive all distributions or shares of 
      surplus, dividend deposits or additions to the Policy now or hereafter 
      made or apportioned thereto, and to exercise any and all options 
      contained in the Policy with respect thereto; provided, that unless and 
      until the Assignee shall notify the Insurer in writing to the contrary, 
      the distributions or shares of surplus, dividend deposits and additions 
      shall continue on the plan in force at the time of this assignment; and

   5. The sole right to exercise all nonforfeiture rights permitted by the 
      terms of the Policy or allowed by the Insurer and to receive all 
      benefits and advantages derived therefrom.

C. It is expressly agreed that the following specific rights, so long as the 
Policy has not been surrendered, are reserved and excluded from this 
assignment and do not pass by virtue hereof:

   1. The right to collect from the Insurer any disability benefit payable in 
cash that does not reduce the amount of insurance;

   2. The right to designate and change the beneficiary;

   3. The right to elect any optional mode of settlement permitted by the 
      Policy or allowed by the Insurer;

The reservation of these rights shall in no way impair the right of the 
Assignee to surrender the Policy completely with all its incidents or impair 
any other right of the Assignee hereunder, and any designation or change of 
beneficiary or election of a mode of settlement shall be made subject to this 
assignment and to the rights of the Assignee hereunder.

D. This assignment is made and the Policy is to be held as collateral security
for any and all liabilities of the undersigned, or any of them, to the 
Assignee, either now existing or that may hereafter arise in the ordinary 
cause of business between any of the undersigned and the Assignee (all of 
which liabilities secured or to become secured are herein called 
"Liabilities").

E. The Assignee covenants and agrees with the undersigned as follows:

   1. That any balance sums received hereunder from the Insurer remaining 
      after payment of the then existing Liabilities, matured or unmatured, 
      shall be paid by the Assignee to the persons entitled thereto under the 
      terms of the Policy had this assignment not been executed.

   2. That the Assignee will not exercise either the right to surrender the 
      Policy or (except for the purposes of paying premiums) the right to 
      obtain policy loans from the Insurer, until there has been default in 
      any of the Liabilities or a failure to pay any premium 

E. (continued)

      when due, nor until twenty days after the Assignee shall have mailed, 
      by first-class mail, to the undersigned at the addresses last supplied 
      in writing to the Assignee specifically referring to this assignment, 
      notice of intention to exercise such right; and 

   3. That the Assignee will upon request forward without unreasonable delay 
      to the Insurer the Policy for endorsement of any designation or change 
      of beneficiary or any election of an optional mode of settlements.

F. The Insurer is hereby authorized to recognize the Assignee's claims to 
rights hereunder without investigating the reason for any action taken by the 
Assignee, or the validity or the amount of the Liabilities or the existence 
of any default therein, or the giving of any notice under Paragraph E(2) 
above or otherwise, or the application to be made by the Assignee of any 
amounts to be paid to the Assignee. The sole signature of the Assignee shall 
be sufficient for the exercise of any rights under the Policy assigned hereby 
and the sole receipt of the Assignee for any sums received shall be a full 
discharge and release therefor to the Insurer. Checks for all or any part of 
the sums payable under the Policy and assigned herein, shall be drawn to the 
exclusive order of the Assignee if, when, and in such amounts as may be, 
requested by the Assignee.

G. The Assignee shall be under no obligation to pay any premium, or the 
principal or interest on any loans or advances on the Policy whether or not 
obtained by the Assignee, or any other charges on the Policy, but any such 
amounts so paid by the Assignee from its own funds, shall become a part of 
the Liabilities hereby secured, shall be due immediately, and shall draw 
interest at the annual percentage rate then in effect for the note or other 
evidence of any Liability.

H. The exercise of any right, option, privilege or power given herein to the 
Assignee shall be at the option of the Assignee, but (except as restricted by 
Paragraph E (2) above) the Assignee may exercise any such right, option, 
privilege or power without notice to, or assent by, or affecting the 
liability of, or releasing any interest hereby assigned by the undersigned or 
any of them.

I. The Assignee may take or release other security, may release any party 
primarily or secondarily liable for any of the Liabilities, may grant 
extensions, renewals or indulgences with respect to the Liabilities, or may 
apply to the Liabilities in such order as the Assignee shall determine, the 
proceeds of the Policy hereby assigned or any amount received on account of 
the Policy by the exercise of any right permitted under this assignment, 
without resorting or regard to the other security.

J. In the event of any conflict between the provisions of this assignment and 
provisions of the note or other evidence of any Liability, with respect to 
the Policy or rights of collateral security therein, the provisions of this 
assignment shall prevail.

K. Each of the undersigned declares that no proceedings in bankruptcy are 
pending against him and that his property is not subject to any assignment, 
for the benefit of creditors.

                        AMENDMENT TO LOAN AGREEMENT


     This Agreement, made as of the 7th day of July, 1995, by and among First 
National Bank of Omaha ("BANK"), a national banking association with 
principal offices in Omaha, Nebraska; TRANSTERRA CO. ("BORROWER"), a Nebraska 
corporation with principal offices in Omaha, Nebraska; AmeriTrade, Inc. 
("AMERITRADE"), a Nebraska corporation with principal offices in Omaha, 
Nebraska; and John Joe Ricketts ("GUARANTOR"), a resident of Douglas County, 
Nebraska.

     Whereas, BANK and BORROWER executed a written Loan Agreement dated 
December 22, 1994 (the "AGREEMENT").

     Whereas, the AGREEMENT was executed contemporaneously with a revolving 
promissory note in the amount of $500,000.00 ("REVOLVING NOTE") and a term 
promissory note in the amount of $1,900,000.00 ("TERM NOTE").

     Whereas, BORROWER desires to borrow additional funds from BANK in the 
amount of $6,000,000 ("TERM NOTE B") in the form attached hereto as Exhibit D.

     Whereas, the parties now desire to amend the AGREEMENT.

     Now, therefore, in consideration of the AGREEMENT, and their mutual 
covenants herein, the parties hereto agree as follows:

1.   All terms and conditions of the LOAN AGREEMENT shall remain in full 
force and effect except as expressly amended herein.  All capitalized terms 
herein shall have the meanings described in the LOAN AGREEMENT.

2.   Section 1. of the AGREEMENT is hereby amended to read, effective 
immediately:

     1.   MINIMUM NET CAPITAL.

          AMERITRADE shall, at all times until full repayment to BANK of any
     and all indebtedness due to BANK as the result of the NOTES, maintain net
     capital in excess of Eight Million ($8,000,000.00) Dollars.  Said net 
     capital is to be calculated according to United States Securities and 
     Exchange Commission Rule 15c 3-1.  Failure to maintain such minimum net 
     capital shall constitute a default sufficient to allow BANK, at its 
     option, to accelerate the loan obligation represented by the NOTES.

3.   Section 4. of the AGREEMENT is hereby amended to read, effective
immediately:




<PAGE>

     4.   MINIMUM NET WORTH.

          BORROWER shall, at all times until full repayment to BANK of any and
     all  indebtedness due to BANK as the result of the NOTES, maintain net 
     worth in excess of Twelve Million ($12,000,000.00) Dollars until 12-31-95.
     At 12-31-95, net worth will be $12,000,000 plus 50% of net income for 
     fiscal year ending 9-30-95; at 12-31-96, $12,000,000 plus 50% of 9-30-96 
     and 9-30-95; at 12-31-97 $12,000,000 plus 50% of 9-30-97, 9-30-96, and 
     9-30-95; and at 12-31-98 $12,000,000 plus 50% of 9-30-98, 9-30-97, 
     9-30-96, and 9-30-95.  This calculation assumes net income is greater 
     than or equal to zero.  Said net worth is to be calculated according to 
     generally accepted accounting principles ("GAAP").  Failure to maintain 
     such minimum net worth shall constitute a default in repayment sufficient 
     to allow BANK, at its option, to accelerate the loan obligation 
     represented by the NOTES.

     5.   GUARANTOR consents to this Agreement, and by his execution hereof 
ratifies and confirms his executed written guarantee of BORROWER'S obligations.

In witness whereof the parties set their hands as of the date first written 
above.

   the Obligations. This Note shall be deemed extended through the date of 
   any advance made by Bank after the original maturity hereof; and any such 
   advance shall constitute principal due under this Note.

2. REPRESENTATION, WARRANTIES AND COVENANTS. Each Maker represents, warrants 
   and covenants as follows:
   This Note, security agreement, deed of trust, mortgage, or other lien 
   document(s), if any, securing the Note have been duly authorized, executed 
   and delivered by the Maker and constitute legal, valid and binding 
   Obligations of Maker.
   This Note evidences a loan for business or agricultural purposes.
   Maker will provide business reports and with such frequency as Bank shall 
   request; and Maker agrees to pay all costs of collection in connection with 
   this Note, including reasonable attorneys' fees and legal expenses.

3. DEFAULTS AND REMEDIES. Upon the occurrence of one of more of the following 
   events of default:
   - Maker fails to pay when due any of the Obligations, or to perform or 
     rectify breach of, any warranty or other undertaking by Maker in this Note 
     or the other Obligations; or breaches any other covenant or condition 
     described in any other document;
   - Any Maker, endorser, surety, or guarantor of any of the Obligations dies, 
     ceases to exist, makes an assignment for the benefit of creditors, becomes 
     insolvent or the subject of bankruptcy or insolvency proceedings;
   - Any representation made to induce Bank to extend credit under this Note or 
     otherwise is false in any material respect when made;
   - A material adverse change, in the opinion of Bank, occurs in the financial 
     or business condition of any Maker or of any endorser, surety or guarantor
     of this Note;
   - The entry of a judgment against any Maker;
   - Filing of any lien against any Maker;
   - The taking possession of any substantial part of the property of any Maker 
     at the instance of any governmental authority;
   - The dissolution, merger, consolidation, or reorganization of any Maker, or 
     other entity liable for this Obligation;
   - Any other event occurs which causes Bank in good faith to deem itself 
     insecure;

   then in such event, all of the Obligations shall, at the option of Bank 
   and without notice or demand, mature and become immediately due and 
   payable; and Bank shall have all rights and remedies for default provided 
   by the Uniform Commercial Code, and any other applicable law and/or the 
   Obligations.

   All costs and expenses incurred by Bank in enforcing its rights under 
   this Note or any mortgage or other lien, endorsement, surety agreement, 
   guarantee relating thereto are the obligations of Maker and are 
   immediately due and payable. Interest shall accrue on such costs and 
   expenses from the date of incurrence at the rate specified herein for 
   delinquent Note payments. Each Maker, endorser, surety and guarantor 
   hereby waives presentment, protest, demand, notice of dishonor, and the 
   defense of any statute of limitations.

4. GENERAL. Without affecting the liability of any Maker, endorser, surety, or 
   guarantor, the holder may, without notice, renew or extend the time for 
   payment, accept partial payments, release or impair any collateral 
   security for the payment of this Note or agree to sue any party liable on 
   it.

   Subject to rights afforded by law, Bank may, at any time and for any 
   reason, charge to or off-set against any amount then on deposit in any 
   account (including a savings certificate), whether or not then due, any 
   and all debts or liabilities (sole, several, joint, or joint and 
   severable, absolute or contingent, due or not due, liquidated or 
   unliquidated, secured or unsecured) then owed to Bank by depositor or in 
   the case of a multiple-party account, by any party to such multiple-party 
   account, and this agreement shall be construed to be the consent of 
   depositor and any such party for the Bank to make such charge or off-set 
   if consent be required by any person or future law.
   
   Bank shall not be deemed to have waived any of its rights upon or under 
   this Note, or under any mortgage or other lien, endorsement, surety 
   agreement, or guarantee unless such waivers be in writing and signed by 
   Bank. No delay or omission on the part of Bank in exercising any right 
   shall operate as a waiver of such right or any other right. A waiver on 
   any one occasion shall not be construed as a bar to or waiver of any 
   right on any future occasion. All rights and remedies of Bank on 
   liabilities or the collateral whether evidenced hereby or by any other 
   instrument or papers shall be cumulative and may be exercised singularly 
   or concurrently.

   Maker, if more than one, shall be jointly and severally liable hereunder 
   and all provisions hereof regarding the liabilities or security of Maker 
   shall apply to any liability or any security of any or all of them. This 
   agreement shall be binding upon the heirs, executors, administrators, 
   assigns or successors of Maker; shall constitute a continuing agreement, 
   applying to all future as well as existing transaction, whether or not of 
   the character contemplated at the date of this Note, and if all 
   transactions between Bank and Maker shall be at any time closed, shall be 
   equally applicable to any new transactions thereafter; shall benefit 
   Bank, its successors, and assigns; and shall so continue in force not 
   withstanding any change in any partnership party hereto, whether such 
   change occurs through death, retirement or otherwise. 
   
   If any party of this Note is a married person, such person or persons 
   hereby separately charges his or her separate estate, including both that 
   now owned and that hereafter acquired, with the payment of this Note.
   
   This Note shall be construed according to the laws of the State of 
   Nebraska. 

   Unless the content otherwise requires, all terms used herein which are 
   defined in the Uniform Commercial Code shall have the meanings therein
   stated.
   
   Any provision of this Note which is prohibited or unenforceable in any 
   jurisdiction shall, as to such jurisdiction, be ineffective to the extent 
   of such prohibition or unenforceability without invalidating the 
   remaining provisions hereof or affecting the validity or enforceability 
   of such provision in any other jurisdiction.

jurisdiction of incorporation or organization, and the Debtor has all 
requisite authority to conduct its business in each jurisdiction in which its 
business is conducted.

   3.2 AUTHORIZATION, VALIDITY AND ENFORCEABILITY. The execution and delivery 
by the Debtor, if a corporation or partnership, of this Security Agreement 
has been duly authorized by proper corporate or partnership proceedings, as 
applicable, and this Security Agreement constitutes a legal, valid and 
binding obligation of the Debtor and creates a security interest which is 
enforceable against the Debtor in all now owned and hereafter acquired 
Collateral.

   3.3 FIRM SECURITIES. Each Pledged Security which is a Firm Security will, 
at the time of pledge, be owned by the Debtor free and clear of any liens, 
security interests or encumbrances, except for the security interest granted 
to the Bank hereunder.

   3.4 CUSTOMER SECURITIES. It is a broker or dealer as defined in the 
Securities Exchange Act of 1934, as amended, and that the pledge of the 
Securities designated as Customer Securities does not and will not contravene 
any provision of Rules 8c-1 or 15c2-1 of the Securities and Exchange 
Commission in effect from time to time. The Debtor has full power and 
authority from each customer to pledge the Customer Securities and to permit 
such Securities to be commingled with securities carried for the account of 
other customers of the Debtor.

Regulation T. The Debtor further represents and warrants to the Bank that (i) 
the proceeds of all extensions of credit constituting the Obligations shall 
be used for one or more of the special purposes described in, and shall meet 
the conditions of, Section 221.5(c) of Regulation U of such Board of 
Governors or, if not so used, (ii) the Obligations will be secured by 
Collateral having a sufficient value to comply with Regulation U.

4. COVENANTS

   From the date of this Security Agreement, and thereafter until this 
Security Agreement is terminated:

   4.1 INSPECTION. The Debtor will permit the Bank, by its representatives 
and agents, to inspect the Collateral, to examine and make copies of the 
records of the Debtor relating thereto, and to discuss the Collateral, and 
the records of the Debtor with respect thereto with, and to be advised as to 
the same by, the Debtor's officers and employees.

   4.2 RECORDS AND REPORTS. The Debtor will maintain complete and accurate 
books and records with respect to the Collateral, and furnish to the Bank 
such reports relating to the Collateral as the Bank may from time to time 
request. With respect to any Collateral which may

<PAGE>

be held by a third party, the Debtor shall instruct such party to mark its 
records or take such other action acceptable to the Bank to reflect the 
Bank's interest in such Collateral.

   4.3 FINANCING STATEMENTS AND OTHER ACTIONS. The Debtor shall, at its own 
expense, keep the Collateral free and clear of all liens, security interests, 
claims, or encumbrances, except in favor of the Bank and defend the Bank's 
interest in the Collateral against the claims of all persons and entities. 
The Debtor will execute and deliver to the Bank all financing statements and 
other documents from time to time requested by the Bank in order to maintain 
a first perfected security interest in the Collateral.

   4.4 UNCERTIFICATED SECURITIES. If any of the Collateral consists of 
uncertificated securities, the Debtor will, or will authorize the Bank to, 
cause the appropriate issuers of uncertificated securities constituting 
Collateral to mark their books and records with the numbers and face amounts 
of all uncertificated securities constituting Collateral and all rollovers 
and replacements therefor to reflect the Lien of the Bank granted pursuant to 
this Security Agreement, or the Debtor will take or cause the issuers or any 
other third parties to take such other action or make such notifications as 
may be required by applicable law.

   4.5 REGISTRATION OF PLEDGED STOCK. The Bank may, at its option, register 
any registerable Collateral in the name of the Bank or its nominee.

   4.6 EXERCISE OF RIGHTS IN PLEDGED STOCK. The Debtor will permit the Bank 
or its nominee at any time after the occurrence of a Default, without notice, 
to exercise all voting and corporate rights relating to the Collateral, 
including, without limitation, exchange, subscription or any other rights, 
privileges or options pertaining to any shares of the stock pledged as 
Collateral and the Pledged Securities as if it were the absolute owner 
thereof.

   4.7 NEGOTIABLE FORM. All Collateral, at the time it becomes part of the 
Collateral, will be in negotiable form (either in bearer form, endorsed in 
blank, with endorsement guaranteed, or such other form satisfactory to the 
Bank, suitable for immediate transfer or registration to the Bank or its 
nominee or at its order).

   4.8 NO LIENS. The Debtor will not create, incur or suffer to exist any 
lien, pledge, security interest or encumbrance on any of the Collateral except 
the security interest created by this Security Agreement. None of the 
Collateral will be held at any clearing corporation or clearing bank in an 
account over which such clearing corporation or bank has any lien or right of 
setoff or if held at a clearing corporation or clearing bank, the Bank shall 
determine the collateral value of such Collateral only upon the excess, if 
any, of the current market value of such Collateral over the amount of any


                                    Page 4
<PAGE>

lien or right of set-off which such clearing corporation or clearing bank 
has. If requested by the Bank, the Debtor will cause such clearing 
corporation or clearing bank to from time to time confirm to the Bank the 
amount of any such lien or right of set-off.

5. DELIVERY, SUBSTITUTION AND WITHDRAWAL OF COLLATERAL.

     5.1. DELIVERY OF COLLATERAL.  The Debtor shall promptly deliver to the 
Bank, its agent or designee, all Collateral pledged to the Bank pursuant to 
this Security Agreement. The Bank agrees that delivery to the Bank may be 
accomplished by transfer of Pledged Securities to the account of the Bank at 
Depository Trust Company in New York, the Midwest Securities Trust Company in 
Chicago or any similar depository acceptable to the Bank and that any 
direction by the Debtor to transfer any Securities to the Bank's account with 
any such depository or any other action taken in accordance with a 
depository's customary procedures regarding pledging of Collateral shall 
constitute a pledge by the Debtor of such Securities to the Bank and the 
confirmation of such pledge. Debtor further agrees that any agent or designee 
of the Bank or any depository or clearing corporation holding the Collateral 
shall have the right to deliver any Collateral held by it for the benefit of 
the Bank to the Bank or to sell such Collateral at the direction of the Bank.

     5.2  WITHDRAWAL OF COLLATERAL.  Provided no Default shall exist prior to 
or after giving effect thereto, the Debtor may withdraw all or any portion of 
the Collateral from time to time if, simultaneously therewith and after 
giving effect to any contemporaneous borrowings, repayments, and 
substitutions of Collateral the outstanding balance of the Obligations is 
secured by Securities of a type acceptable to the Bank having a collateral 
value determined by the Bank in its sole discretion to be satisfactory to it. 
No withdrawal or substitution of Collateral shall be effective until the Bank 
shall have consented to such withdrawal or substitution. Notwithstanding the 
foregoing, the Bank shall not be obligated to release any collateral in 
violation of the release and substitution rules of Regulation U.

     5.3.  SALE OF SECURITIES.  Unless the then outstanding Obligations are 
secured by other Securities of a type acceptable to, and having a collateral 
value satisfactory to, the Bank, the Debtor shall, promptly upon its receipt 
of any proceeds from the sale, pledge or other disposition of any of the 
Collateral, and in no event more than 10 days after such proceeds are 
received by the Debtor, deliver such proceeds to the Bank to be deposited in 
the special collateral account established pursuant to Section 9.2.

     6.2.  ACCELERATION AND REMEDIES.  If any Default occurs, then, upon the 
election of the Bank or, in the case of a Default under Section 6.1.6 or 
6.1.7, without any action on the part of the Bank, the Obligations shall 
immediately become due and payable without presentment, demand, protest or 
notice of any kind, all of which are hereby expressly waived, and the Bank 
may exercise any or all of the rights and remedies provided (i) in this 
Security Agreement, (ii) to a secured party when a debtor is in default under 
a security agreement by the Illinois Uniform Commercial Code and (iii) by any 
other applicable law including, without limitation, any law governing the 
exercise of a bank's right of setoff or bankers' lien.  With respect to 
Obligations which are contingent and cannot be accelerated by their nature, 
the Bank may require the Debtor to deposit cash or other acceptable 
collateral in an amount sufficient to cover principal and interest which will 
have accrued by the maturity date on said Obligations to be held as security

     are located, to take possession of all or any part of the Collateral and 
     to remove all or any part of the Collateral.

7.  WAIVERS, AMENDMENTS AND REMEDIES.

     No delay or omission of the Bank to exercise any right or remedy granted 
under this Security Agreement or under applicable law shall impair such right 
or remedy or be construed to be a waiver of any Default or an acquiescence 
therein, and any single or partial exercise of any such right or remedy shall 
not preclude other or further exercise thereof or the exercise of any other 
right or remedy, and no waiver, amendment or other variation of the terms, 
conditions or provisions of this Security Agreement whatsoever shall be valid 
unless in writing signed by the Bank, and then only to the extent in writing 
specifically set forth. All rights and remedies contained in this Security 
Agreement or by law afforded shall be cumulative and all shall be available 
to the Bank until the Obligations have been paid in full.

     Obligations in such order as the Bank elects, and;

          (c)  THIRD, the balance, if any, after all of the Obligations have 
     been satisfied, shall be deposited by the Bank into the Debtor's general
     operating account with the Bank, or to such other account as the Debtor 
     may direct in writing.

9.  GENERAL PROVISIONS.

     9.1.  DISPOSITION OF COLLATERAL.  After Default, the Bank may dispose of 
all or any part of the Collateral in such a manner and upon such terms as the 
Bank, in its sole discretion, shall determine.  If any notification of a 
proposed disposition of the Collateral is

                                    Page 8

<PAGE>

required by applicable law, such notice shall be deemed reasonable if sent to 
the Debtor, addressed as set forth in Section 10, at least 3 days prior to 
any public sale or the time after which any private sale may be made.  The 
Debtor hereby expressly agrees that the Pledged Securities are securities of 
a type customarily sold on a recognized market and as such, no notice of any 
sale or disposition of any of the Pledged Securities need be given unless 
trading in a particular Security shall have been suspended or ceased on all 
recognized markets at such time.

    9.2  SPECIAL COLLATERAL ACCOUNT.  The Bank may require all cash proceeds 
of the Collateral to be deposited in a special non-interest bearing cash 
collateral account with the Bank and held there as security for the 
Obligations.  The Debtor shall have no control whatsoever over said cash 
collateral account.  If no Default has occurred or is continuing, the Bank 
shall from time to time deposit the collected balances in said cash 
collateral account into the Debtor's general operating account with the Bank 
or, upon notice to the Debtor, apply such balances to payment of the 
Obligations.  If any Default has occurred and is continuing, the Bank may, at 
its option, apply the collected balances in said cash collateral account to 
the payment of the Obligations whether or not the Obligations shall then be 
due, or hold said cash collateral as Collateral hereunder.

    9.3  BANK PERFORMANCE OF DEBTOR OBLIGATIONS.  Without having any 
obligation to do so, the Bank may perform or pay any obligation which the 
Debtor has agreed to perform or pay in this Security Agreement and the Debtor 
shall reimburse the Bank for any amounts paid by the Bank pursuant to this 
Section.  The Debtor's obligation to reimburse the Bank pursuant to the 
preceding sentence shall be an Obligation payable on demand.

    9.4  AUTHORIZATION FOR BANK TO TAKE CERTAIN ACTION.  The Debtor 
irrevocably authorizes the Bank at any time and from time to time in the 
sole discretion of the Bank and appoints the Bank as its attorney in fact to 
act on behalf of the Debtor (i) to execute on behalf of the Debtor as 
debtor and to file financing statements necessary or desirable in the Bank's 
sole discretion to perfect and to maintain the perfection and priority of the 
Bank's security interest in the Collateral, (ii) to indorse and collect any 
cash proceeds of the Collateral, (iii) to file a carbon, photographic or 
other reproduction of this Security Agreement or any financing statement with 
respect to the Collateral as a financing statement in such offices as the 
Bank in its sole discretion deems necessary or desirable to perfect and to 
maintain the perfection and priority of the Bank's security interest in the 
Collateral, and (iv) to apply the proceeds of any Collateral received by the 
Bank to the Obligations as provided in Section 8.

    9.5  SPECIFIC PERFORMANCE OF CERTAIN COVENANTS.  The Debtor acknowledges 
and agrees that a breach of any of the covenants contained in Sections 4.4, 
4.8, 5.1, 5.3, 6.3 and 9.2 will cause irreparable injury to the Bank, that 
the Bank has no adequate remedy


                                    Page 9

<PAGE>

at law in respect of such breaches and therefore agrees, without limiting the 
right of the Bank to seek and obtain specific performance of other 
obligations of the Debtor contained in this Security Agreement, that the 
covenants of the Debtor contained in the Sections referred to in this Section 
shall be specifically enforceable against the Debtor.

    9.6.  USE AND POSSESSION OF CERTAIN PREMISES.  Upon the occurrence of a 
Default, the Bank shall be entitled to occupy and use any premises owned or 
leased by the Debtor where any of the Collateral or any records relating to 
the Collateral are located until the Obligations are paid or the Collateral 
is removed therefrom, whichever first occurs, without any obligation to pay 
the Debtor for such use and occupancy.

    9.7.  DISPOSITIONS NOT AUTHORIZED.  The Debtor is not authorized to sell 
or otherwise dispose of the Collateral except as set forth in Section 5.2 and 
notwithstanding any course of dealing between the Debtor and the Bank or 
other conduct of the Bank, no authorization to sell or otherwise dispose of 
the Collateral (except as set forth in Section 5.2) shall be binding upon the 
Bank unless such authorization is in writing signed by the Bank.

    9.8.  DEFINITION OF CERTAIN TERMS.  Terms defined in the Illinois Uniform 
Commercial Code which are not otherwise defined in this Security Agreement are 
used in this Security Agreement as defined in the Illinois Commercial Code as 
in effect on the date hereof.

    9.9.  BENEFIT OF AGREEMENT.  The terms and provisions of this Security 
Agreement shall be binding upon and inure to the benefit of the Debtor and 
the Bank and their respective successors and assigns, except that the Debtor 
shall not have the right to assign its rights under this Security Agreement 
or any interest herein, without the prior written consent of the Bank.

    9.10.  SURVIVAL OF REPRESENTATIONS.  All representations and warranties 
of the Debtor contained in this Security Agreement shall survive the 
execution and delivery of this Security Agreement.

    9.11.  TAXES AND EXPENSES.  Any taxes (excluding income taxes) payable or 
ruled payable by Federal or State authority in respect of this Security 
Agreement shall be paid by the Debtor, together with interest and penalties, 
if any.  The Debtor shall reimburse the Bank for any and all out-of-pocket 
expenses and interest charges (including reasonable attorneys', auditors', and 
accountants' fees and reasonable time charges of attorneys, paralegals, 
auditors and accountants who may be employees of the Bank) paid or incurred 
by the Bank in connection with the preparation, execution, delivery, 
administration, collection and enforcement of this Security Agreement and in 
the audit, analysis, administration, collection, preservation or sale of

                                    Page 10

<PAGE>


the Collateral (including the expenses and charges associated with any periodic
or special audit of the Collateral).  The obligations of the Debtor under this
Section shall survive termination of this Security Agreement.

    9.12.  HEADINGS.  The title of and section headings in this Security
Agreement are for convenience of reference only, and shall not govern the
interpretation of any of the terms and provisions of this Security Agreement.

    9.13.  TERMINATION.  This Security Agreement shall continue in effect
(notwithstanding the fact that from time to time there may be no Obligations or
commitments therefore outstanding) until (i) the Bank has received written
notice of its termination from the Debtor and (ii) no Obligations or commitments
of the Bank which would give rise to any Obligations shall be outstanding.

    9.14.  ENTIRE AGREEMENT.  This Security Agreement embodies the the entire 
agreement and understanding between the Debtor and the Bank relating to the 
Collateral and supersedes all prior agreements and understandings between the 
Debtor and the Bank relating to the Collateral.

accordance with the laws of the State of Illinois applicable to contracts with
national banking associations made and performed wholly in Illinois.

does hereby agree to indemnify and keep harmless the Bank, and its 
successors, assigns, agents and employees, from and against any and all 
liabilities, damages, penalties, suits, costs, and expenses of any kind and 
nature, imposed on, incurred by or asserted against the Bank, or its 
successors, assigns, agents and employees, in any way relating to or arising 
out of this Security Agreement, or the purchase, ownership, delivery, 
possession, use, sale or other disposition of any Collateral except for any 
such events arising out of the gross negligence or wilful misconduct by the 
Bank, its successors, assigns, agents and employees.

    9.17.  CONSENT TO JURISDICTION AND WAIVER OF JURY TRIAL.  The Debtor hereby
irrevocably submits to the non-exclusive jurisdiction of any United States
federal of Illinois state or local court sitting in Cook County, Illinois in any
action or proceedings arising out of or related to this Security Agreement and
hereby irrevocably agrees that all claims in respect of such action or
proceeding may be heard and determined in any such court.  The Debtor hereby

                            MASTER BROKER LOAN NOTE

                                                             Chicago, Illinois
                                                        Date: October 24, 1989

     FOR VALUE RECEIVED, Ameritrade, Inc. (the "Company") promises to pay to 
the order of The First National Bank of Chicago (the "Bank"), in lawful money 
of the United States at the office of the Bank at One First National Plaza, 
Chicago, Illinois, or as the Bank may otherwise direct the aggregate 
outstanding unpaid principal amount of loans ("Loans") advanced hereunder, 
together with interest as provided below.

     Except as provided in the following paragraph, each Loan hereunder shall 
be due and payable on the day following the day on which the Loan is made and 
shall bear interest at the rate per annum quoted to the Company by the Bank 
("Transaction Rate"), which rate shall be applicable to and in effect for the 
day on which it is quoted.

     In addition to the Transaction Rate, the Company and the Bank may agree 
to a fixed interest rate ("Fixed Rate") and a specific term in excess of one 
day for a Loan (a "Fixed Rate Loan") at the time of borrowing. Each such 
Fixed Rate Loan shall be due and payable at the specified maturity of such 
Loan.

     Unless another rate is specifically agreed to by the Bank for any Loan, 
a Transaction Rate Loan or Fixed Rate Loan not paid when due shall thereafter 
be payable on demand and bear interest at a rate equal to the greater of the 
corporate base rate of interest announced by the Bank from time to time, 
changing when and as the corporate base rate changes or the then applicable 
Fixed Rate or Transaction Rate.

     On each business day of the Bank for which the Company desires the Bank 
to make a Loan, any person authorized to borrow on behalf of the Company (an 
"authorized person") may request by telephone a quote for an interest rate 
for such Loan. If the Bank elects to offer a Loan to the Company and if the 
Company elects to accept the rate at the time such rate is quoted by the 
Bank, then the Bank shall make a Loan at the stipulated rate on such day. Any 
authorized person may request a Loan or an interest rate quote hereunder and 
give the Bank information relevant to such Loan by telephone or telex. The 
Company agrees that, in implementing this arrangement, the Bank is authorized 
to honor requests which it believes, in good faith, to emanate from an 
authorized person acting pursuant to this note, whether in fact that be the 
case or not. The Company will confirm the terms of each Loan by mailing a 
confirmation letter to the bank signed by an authorized person.

                                    Page 14

<PAGE>

     Each payment of principal hereunder shall be made in immediately 
available funds (or clearinghouse funds if the Loan was made in clearinghouse 
funds). Interest on all Loans shall be due and payable in immediately 
available funds on the last day of each month during which a Loan is 
outstanding. If any payment shall become due and payable on a Saturday, 
Sunday or legal holiday under the laws of Illinois, such payment shall be 
made on the next succeeding business day in Illinois and any such extended 
time of the payment of principal shall be included in computing interest at 
the rate this note bears in connection with such payment. All interest 
hereunder shall be computed for the actual numbers of days elapsed on a 
360-day year basis.

     Fixed Rate Loans may be prepaid prior to the agreed maturity or that 
Loan only upon payment to the Bank of all loss or cost to the Bank resulting 
from such prepayment, including without limitation, any loss or cost in 
liquidating or employing deposits acquired to fund or maintain such Fixed 
Rate Loan.

     The Company hereby authorizes the Bank to record Loans, maturities, 
repayments, interest rates and payment dates on the schedule on the reverse 
side of this note or otherwise on the Bank's books and records in accordance 
with the Bank's usual practices. The obligation of the Company to repay each 
Loan made hereunder shall be absolute and unconditional notwithstanding any 
failure of the Bank to enter such amounts on such schedule and, in the event 
of disagreement as to the terms of a transaction, the Bank's records shall 
govern, absent manifest error. The Company hereby authorizes the Bank to 
deposit the proceeds of Loans to, and to charge payments of principal and 
interest against, the Company's deposit account with the Bank or as otherwise 
requested by the Company. All Loans shall be made by the Bank in immediately 
available funds unless the Company specifically requests clearinghouse funds 
when such Loan is requested.

     Nothing in this note shall constitute a commitment to make Loans to the 
Company. In addition to, and without limitation of, any rights of the Bank 
under applicable law, if any amount payable hereunder is not paid, when due, 
there is any material adverse change in the Company's financial condition, 
there is a default under any agreement governing indebtedness of the Company, 
there is a default under any security agreement or other agreement between 
the Company and the Bank, any petition is filed by or against the Company 
under the United States Bankruptcy Code or similar state law or if the 
Company becomes insolvent, howsoever evidenced, the Bank may declare all 
unpaid principal and interest on the Loans and unpaid fees immediately due 
and payable and any indebtedness from the Bank to the Company may be offset 
and applied toward the payment of all unpaid principal, interest and fees 
payable hereunder, whether or not such amounts or any part thereof, shall 
then be due. The Company expressly waives any presentment, demand, protest or 
notice in connection with this note

                                    Page 15

<PAGE>

now, or hereafter, required by applicable law and agrees to pay all costs and 
expenses of collection. The Company represents to the Bank, in accordance 
with Regulation U of the Board of Governors of the Federal Reserve System, 
that it is subject to Regulation T promulgated by such Board of Governors and 
that it does not extend or maintain credit to or for customers except in 
accordance with the provisions of such Regulation T. This note and all Loans 
made hereunder, shall, to the extent permitted by law be secured by all 
collateral, if any, now or hereafter pledged by the Company to the Bank 
together with all proceeds thereof to the extent permitted by law.

     This note shall be governed by the internal laws (and not the law of 
conflicts) of the State of Illinois, giving effect, however, to federal laws 
applicable to national banks.

                             OFFICE BUILDING LEASE

     THIS LEASE, made and entered into this 14th day of July, 1993, by and 
between John Joe and Marlene M. Ricketts, husband and wife, hereinafter called
"Landlord", and TransTerra Co. a Nebraska corporation, hereinafter called
"Tenant".


                              W I T N E S S E T H:

     1.   DEMISED PREMISES.  Landlord does hereby demise and lease unto Tenant,
and Tenant does hereby lease and hire from Landlord, the following described
premises situated in Douglas County, Nebraska, to-wit:

     The office building and land located at 4211 South 102nd Street, Omaha,
     Nebraska, depicted on the survey attached hereto as Exhibit "A" attached
     and by this reference incorporated herein.

Such demised premises hereinafter are referred to, as the context may require,
as the "Premises"; the "Building"; and the "Land".

     2.   TERM.  The term of this lease shall be for twenty (20) years plus
that additional period which shall be necessary to enable the term of this
lease to end on the last day of a calendar year and shall commence on the date
on which Landlord delivers possession of the Premises to Tenant.

     3.   BASE RENT.  Tenant agrees to pay to Landlord, without demand,
deduction, or setoff, at Omaha, Nebraska, or at such other place as Landlord
from time to time may designate in writing, a fixed  minimum annual base rent
in the amount of Five Hundred Ninety One Thousand Forty and no/100 Dollars
($591,040.00), which sum shall be payable by Tenant in equal consecutive
monthly installments of Forty Nine Thousand Two Hundred Fifty Three and 33/100
Dollars ($49,253.33) each, in advance, on the first day of each month during
the term of this lease.  Rent for any period of less than a calendar month
shall be prorated on a daily basis and shall be paid within ten (10) days after
the end of the period for which it is due.

     4.   PERMITTED USE.  Tenant may use and occupy the Premises for an office 
building and no other purpose.  Tenant agrees to conduct its business at
all times in a responsible and reputable manner and at all times to comply with
all laws, ordinances, and governmental regulations affecting the Premises and
its cleanliness, safety, occupancy, and use.  Tenant shall not commit or suffer
to be committed any waste upon the Premises.

     5.   LANDLORD'S COVENANTS.  Landlord covenants that it is the owner of the
real estate described in paragraph 1 of this lease;


<PAGE>

and that Landlord has full power and authority to make this lease with Tenant.
Landlord further covenants that Tenant, upon the complete and timely payment of
all rent and performance of Tenant's other obligations under this lease, shall
peacefully and quietly have, hold, and enjoy the occupancy of the Premises
throughout the term of this lease or until this lease is sooner terminated in
accordance with its provisions without any disturbance from Landlord or anyone
claiming by, through, or under Landlord.

     6.   MECHANIC'S LIENS. If any mechanic's lien or other lien is filed
against the Building or Land or any part thereof for any reason whatsoever by
reason of Tenant's acts or omissions or because of a claim against Tenant, then
Tenant shall cause each such lien to be cancelled and discharged of record by
bond or otherwise within ten (10) days after notice by Landlord and shall hold
Landlord harmless from any costs, expenses, damages, or liabilities directly or
indirectly resulting from such lien.

     7.   MAINTENANCE AND REPAIRS.  Landlord, at its expense, shall keep the
Premises neat, orderly, safe, and clean and promptly shall make any and all
repairs and replacements to the Premises, to the Building and the fixtures and
equipment constituting a part thereof, and to the Land which may be required.

     8.   ENVIRONMENTAL MATTERS.  For purposes of this paragraph "Hazardous
Substance" shall have the meaning given to such phrase in the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended 
(42 USC Section 9601, ET SEQ.) and also shall include any flammable explosives,
radioactive materials, hazardous materials, hazardous wastes, hazardous or
toxic substances, or related materials which are regulated by any federal,
state, or local law, ordinance, rule, regulation, or policy relating to the
protection of the environment.  For purposes of this paragraph an
"Environmental Regulation" is any federal, state, or local law, ordinance,
rule, regulation, or policy governing the use, storage, treatment,
transportation, manufacture, refinement, handling, production, discharge,
emission, or disposal of any Hazardous Substance.  Tenant shall not use, store,
handle, produce, dispose of, discharge, take any other actions, or allow anyone
else to take any of such actions, with respect to any Hazardous Substance in,
at, on, or from the Premises in any manner which violates any Environmental
Regulation.  During the term of this lease and any other periods of Tenant's
occupancy of the Premises, Tenant at its expense shall obtain, maintain in
effect, and comply with all permits and licenses required by any Environmental
Regulation applicable to Tenant or the Premises.  Within three (3) business
days after Tenant is notified or otherwise becomes aware of any actual or
potential violation or alleged violation of any Environmental Regulation
involving or relating to the Premises, Tenant shall notify Landlord in writing
of such actual or potential violation or alleged violation and promptly shall
deliver to Landlord copies of any written materials that Tenant may have or
thereafter receive which pertain to or


                                       2


<PAGE>

purport to give notice of such actual or potential violation or alleged
violation.  Tenant at its expense promptly shall conduct and complete all
investigations, studies, sampling, testing, removal, and other actions
necessary to clean up and remove from the Premises any Hazardous Substance
which may have been introduced into or upon the Premises during the term of
this lease or any other period of occupancy of the Premises by Tenant, all in
accordance with and as required by any applicable Environmental Regulation and
the orders and directions of federal, state, and local governmental authorities
having jurisdiction over the Premises or such actions.  Tenant shall provide
Landlord and Landlord's agents or representatives with access to the Premises
and to Tenant's files and records at all reasonable times for the purpose of
verifying Tenant's compliance with the requirements of this paragraph.  Tenant
shall indemnify Landlord against and hold Landlord harmless from any and all
claims, demands, penalties, fines, liabilities, settlements, damages, costs, or
expenses of whatever kind or nature (including but not limited to attorney 
fees, fees of environmental consultants, and laboratory fees) known or unknown,
contingent or otherwise, arising out of or in any way related to the presence,
release, threatened release, or disposal of any Hazardous Substance in, upon,
or from the Premises or arising out of or in any way related to the violation
by Tenant or the Premises of any Environmental Regulation during the term of
this lease and any other period of Tenant's occupancy of the Premises.  The
obligations of Tenant under this paragraph shall survive the termination of
this lease and of Tenant's occupancy of the Premises.

     9.   SIGNS AND TRADE FIXTURES.  Tenant shall not install any signs upon
the exterior of the Building without the prior written consent of Landlord,
which consent shall not be unreasonably withheld.  Tenant understands that the
Building will be subject to certain architectural and other restrictions, and
it shall not be considered to be unreasonable for Landlord to withhold its
consent to the installation of any such signs in order to insure compliance
with such restrictions.  The immediately preceding sentence shall not be deemed
in any way to limit Landlord's considerations in determining whether or not to
give its consent to the installation of any signs upon the exterior of the
Building, and Landlord and Tenant agree that there may be reasonable causes
other than such architectural and other restrictions for Landlord to withhold
such consent.  Tenant may install in or upon the Premises and remove therefrom
such trade fixtures as it may deem necessary or appropriate to its business
operations; provided, that the removal of such trade fixtures shall cause no
material damage to the Premises.  Any damage which may be caused to the
Premises by the removal of any of Tenant's trade fixtures shall be repaired by
Tenant at its expense forthwith upon the removal of any such trade fixtures;
provided, that such damage is not caused by the negligence of Landlord or its
contractors, agents, servants, employees, or anyone else for whom Landlord may
be responsible.

     10.  ALTERATIONS BY TENANT.  Tenant shall make no alterations or additions
whatsoever to the Premises or the Building or to any of the mechanical,
electrical, plumbing, heating, air conditioning, sprinkler, or sewer systems
serving the Premises or the Building without prior written consent of Landlord,
which consent shall not be unreasonably withheld.  At the time Landlord's
consent to any alterations or additions is sought, Tenant shall submit to
Landlord plans and specifications for such work, together with a statement of
the estimated cost of such work.  All such alterations or additions shall be
completed in a good and workmanlike manner with first-class materials.  At
Landlord's option, any additions or alterations made to the Premises by Tenant
shall remain a part of the Premises and be surrendered therewith upon the
termination of this lease, or upon the termination of this lease Tenant shall
restore the Premises to their original condition at Tenant's expense.

     11.  INDEMNIFICATION.  Tenant agrees to indemnify Landlord against and to
hold Landlord harmless from any and all claims or demands of any third party
arising from or based upon any alleged act, omission, or negligence of Tenant
or Tenant's contractors, concessionaires, licensees, agents, servants,
invitees, employees, or anyone else for whom Tenant may be responsible. In the
event that Landlord shall be made a party to any litigation commenced by any
third party against Tenant, for which there is no liability on Landlord's part,
then Tenant shall indemnify Landlord against and hold Landlord harmless from
such litigation and shall pay all costs, expenses, and reasonable attorneys'
fees incurred or paid by Landlord in connection with such litigation.

     12.  PUBLIC LIABILITY INSURANCE.  Landlord at its expense at all times
during the term of this lease and any other period of occupancy of the Premises
by Tenant shall provide and maintain with respect to the Premises general
public liability insurance, with both Landlord (and any mortgagee of Landlord)
and Tenant as named insureds, which insurance shall provide coverage of not
less than $1,000,000 for personal injury and property damage.  Upon Tenant's
written request Landlord shall furnish to Tenant appropriate certificates
evidencing that such insurance is in force.

     13.  HAZARD INSURANCE.  Landlord at all times during the term of this
lease and any other period of occupancy of the Premises by Tenant shall provide
and maintain at Landlord's expense with respect to the Building fire and
extended coverage insurance to the extent of the replacement cost of the
Building, on a not less than eighty percent (80%) co-insurance basis and rent
insurance satisfactory to Landlord.  Tenant understands and agrees that such
insurance will not cover any of Tenant's property, including but not limited to
leasehold improvements, in the absence of a prior written agreement between
Landlord and Tenant with respect to such coverage.

<PAGE>

     14.  EMPLOYEE PARKING.  Tenant's employees shall park their motor vehicles
only in the areas of the parking lot not specifically designated by Landlord
for visitors' use.

     15.  ASSIGNMENT AND SUBLETTING.  Tenant shall have no right to assign this
lease (whether voluntarily or by operation of law) or to sublet the Premises
without the prior written consent of Landlord, which consent shall not
unreasonably be withheld; provided that, notwithstanding Landlord's giving of
such consent, Tenant shall remain primarily liable to Landlord for the payment
of the rent and the performance of Tenant's obligations under this lease, and
in the event that any such sublease approved by Landlord shall provide for the
payment of rent in excess of rent payable under this lease, such excess rent
shall be paid to Landlord as it becomes due under the terms of such sublease.

     16.  ENTRY BY LANDLORD.  Landlord shall have the right to enter the
Premises at all reasonable hours for the purpose of inspecting the Premises and
for all other necessary purposes; provided, that such entry shall not
unreasonably interfere with the conduct of Tenant's business.  For a period
commencing six (6) months prior to the termination of this lease, Landlord may
have reasonable access to the Premises for the purpose of exhibiting the
Premises to prospective tenants thereof and may display "For Rent" signs on the
Premises.

     17.  BUILDING OPERATIONS.  Landlord shall furnish reasonably adequate
heating and air conditioning for the Premises during normal business hours and
at such other times as Landlord may deem necessary or desirable for the
Building.  Landlord shall furnish water and electricity for the Premises;
provided, that Tenant shall not install or use any equipment in the Premises
which requires unusual or excessive amounts of electricity without Landlord's
prior written consent.  Landlord shall furnish reasonably adequate janitorial
service after normal business hours and during normal business hours on such
special occasions as Landlord may deem necessary.  Tenant agrees that Landlord
shall have the right to discontinue any service above mentioned or any part
thereof whenever and during any period for which bills for rent or other
services are not promptly paid by Tenant.  Tenant further agrees that Landlord
shall not be liable for damages, nor shall the rent provided for in this lease
be abated, for Landlord's failure to furnish or delay in furnishing any service
above mentioned when such failure to furnish, or delay in furnishing, is
occasioned, in whole or in part, by reasonably necessary repairs, renewals, or
improvements, any strike or labor controversy, any accident or casualty
whatever, any unauthorized act or default of any employee of landlord, or nay
other cause or causes beyond the reasonable control of Landlord; provided, that
Landlord shall follow reasonable maintenance and replacement schedules to
maintain the Building and the fixtures and equipment constituting a part
thereof in good operating condition.

<PAGE>

     18. DAMAGE BY CASUALTY.  If, during the term of this lease, the Premises 
shall be so damaged by fire or other casualty as to be rendered wholly or 
partially untenantable, then the rent shall be abated in proportion to 
Tenant's loss of use of the Premises while the Premises remain wholly or 
partially untenantable; and in the event of such damage Landlord shall, 
within thirty (30) days after such damage, elect whether to repair the 
Premises or to terminate this lease and notify Tenant in writing of such 
election. If Landlord elects not to repair the Premises, then this lease 
shall be deemed to have been terminated as of the date of such damage; but 
Landlord and Tenant shall fulfill all of their obligations under this lease 
which accrued on or before the effective date of such termination.  If 
Landlord elects to repair the Premises, then Landlord shall complete such 
repairs within 270 days after the occurrence of such damages and, upon 
completion thereof, shall so notify Tenant in writing whereupon Tenant's 
obligation to pay the full amount of its rent under this lease shall resume 
as of the date the repaired Premises are made available to Tenant for 
occupancy.

     19.  BANKRUPTCY.  In the event that Tenant becomes subject to voluntary or
involuntary proceedings under the Bankruptcy Reform Act of 1978 (the "Act"),
Landlord shall have all of the rights and remedies which are available to a
Landlord under the Act in such event.

     20.  HOLDOVER.  If Tenant remains in possession of the Premises after the
termination of this lease without the execution of a new lease, then Tenant
shall be deemed to be occupying the Premises as a tenant from month-to-month,
subject to all of the conditions, provisions, and obligations of this lease.

     21.  WAIVERS.  One or more waivers by Landlord or Tenant of a breach of
any covenant or condition by the other of them shall not be construed as a
waiver of the subsequent breach of the same covenant or condition, and the
consent or approval by Landlord or Tenant to or of any act by either requiring
the other's consent or approval shall not be deemed to waive or render
unnecessary either party's consent to or approval of any subsequent similar act
by the other party.

     22.  WAIVER OF CLAIMS.  Tenant agrees that (except for the willful
misconduct of Landlord and Landlord's agents and employees) Landlord and
Landlord's agents and employees shall not be liable for and Tenant hereby
waives all claims for damage to persons or property sustained by Tenant or any
person claiming by, through, or under Tenant resulting from any accident or
occurrence in or upon the Premises or any part of the Building, or Land,
including but not limited to claims for damage resulting from (a) any equipment
or appurtenances becoming out of repair; (b) injury done or occasioned by fire
or wind or other natural condition or event; (c) any defect in or failure of
plumbing, heating, sprinkler, or air conditioning equipment, electrical wiring
or equipment, gas, water,

                                       6


<PAGE>

or steam pipes, elevators, stairs, porches, railings, driveways or walks; (d)
broken glass; (a) the backing up of any sewer pipe or downspout; (f) the
bursting, leaking, or running over of any tank, tub, washstand, water closet,
waste pipe, drain, or any other pipe or tank in, upon, or about the Premises,
or the stoppage of any utility service for the purpose of inspecting the system
or making repairs thereto; (g) the escape of steam or hot air; (h) water, snow,
or ice being upon or coming through the roof, skylight, trap door, stairs,
walks, or any other place upon or near the Premises or otherwise; (i) the
falling of any fixtures, plaster, or stucco; and (j) any act, omission, or
negligence of co-tenants or of other persons or occupants of the Building or of
adjoining or contiguous buildings or of owners of adjacent or contiguous
property.

     23.  NOTICES.  Whenever under this lease a provision is made for notice of
any kind, such notice and the service thereof shall be deemed sufficient if
such notice to Tenant is in writing addressed to Tenant at the Premises, and is
delivered personally or sent by certified mail with postage prepaid, and if
such notice to Landlord is in writing addressed to Landlord at ________________
____________________________________ and is delivered personally or sent by 
certified mail with postage prepaid.  Either party may by notice to the other 
party change the address at which it wishes to receive any notice given under 
this lease.

     24.  RELATIONSHIP OF PARTIES.  Nothing contained in this lease shall be
deemed or construed by the parties hereto, or by any third party, to create the
relationship of principal and agent or of partnership or of joint venture
between the parties hereto, it being understood and agreed that neither the
method of computation of rent, nor any other provision contained herein, nor
any acts of the parties hereto shall be deemed to create any relationship
between the parties hereto other than the relationship of landlord and tenant.

     25.  REAL ESTATE TAXES.  Landlord agrees to pay, prior to delinquency, the
general real estate taxes on the Land and Building whose delinquency dates
occur during the term of this lease.

     26.  DELAYS IN PERFORMANCE.  The performance by Landlord and Tenant of any
of their respective obligations or undertakings provided for in this lease
(except the payment of rent or any other sums of money payable by Tenant under
this lease) shall be excused and no default shall be deemed to exist in the
event and so long as the performance of any such obligation or undertaking is
prevented, delayed, retarded, or hindered by any act of nature, fire,
earthquake, flood, explosion, action of the elements, war, riot, failure of
transportation, strikes, lockouts, action of labor unions, condemnation, laws,
orders of government or civil or military authorities, inability to procure
labor, equipment, facilities, materials or supplies in the open market, or any
other cause beyond the control of Landlord or Tenant, as the case may be.


                                       7


<PAGE>

     27.  DELINQUENT PAYMENTS. If any rent or other sums due and payable by
Tenant under this lease are not paid within ten (10) days after such rent, or
other sums are due and payable, then such unpaid base rent, additional rent, or
other sums shall bear interest at the rate of twelve (12%) per cent per annum,
or, if lower, at the maximum contract interest rate allowable by law from their
respective due dates until paid.

     28.  DEFAULT.  If Tenant defaults in the payment of any rent or other sums
due and payable to Landlord under this lease and such default continues for a
period of ten (10) days, or if Tenant shall violate or default in the
performance of any covenants, agreements, stipulations or other conditions
contained herein (other than the payment of rent and other sums payable under
this lease) and such violation or default continues for a period of thirty (30)
days after written notice of such violation or default has been given by
Landlord to Tenant (or, in the case of a default not curable within thirty (30)
days, if Tenant shall fail to commence to cure the same within thirty (30) days
and thereafter proceed diligently to complete the cure thereof), then
Landlord, at its option, upon fifteen (15) days prior written notice to Tenant
may re-enter and repossess the Premises, with or without process of law, and
declare this lease terminated and the term of this lease ended forthwith.
Landlord may use such force as may be necessary to remove all persons and
property then located in the Premises, and Landlord shall not be liable for
damages by reason of such re-entry and repossession.  Notwithstanding such re-
entry and repossession by Landlord, the liability of Tenant for the payment of
the rent and other sums due hereunder and for the performance of Tenant's other
obligations hereunder for the balance of the term of this lease shall not be
relinquished or extinguished; and Landlord at any time may commence such one or
more actions as it may deem necessary to collect any sums due from Tenant under
this lease.  In the event of any such re-entry and repossession, Landlord shall
have the right to relet all or any portion of the Premises upon such terms and
conditions as Landlord may deem appropriate; and any such reletting shall not
relieve Tenant of any of its obligations to Landlord under this lease, except
to the extent of any net rentals actually received by Landlord from such
reletting after deducting all of Landlord's expenses (including but not limited
to legal expenses, brokerage commissions, and the costs of remodeling the
Premises so as to render it suitable for reletting) incurred in preparing for
and accomplishing such reletting.  Tenant further agrees to pay, in addition to
the rentals and other sums agreed to be paid hereunder, such additional sums as
a court of competent jurisdiction may adjudge reasonable as attorneys' fees in
any suit or action resulting in a judgment in favor of Landlord instituted by
Landlord to enforce the provisions of this lease or the collection of the
rentals or other sums payable by Tenant hereunder.

     29.  SHORT-FORM LEASE.  Both parties agree not to record this lease; but
each party hereto agrees, at the request of the other, to execute a so-called
"short form" of lease in form recordable and


                                       8


<PAGE>

reasonably satisfactory to Landlord's attorneys.  In no event shall such "short
form" lease set forth the rental and other charges payable by Tenant under this
lease, and any such "short form" lease shall expressly state that it is
executed pursuant to the provisions contained in this lease and is not intended
to vary the terms and conditions of this lease.

     30.  SUBORDINATION.  Landlord may assign its rights under this lease as
security to the holders of one or more mortgages (which term shall include a
mortgage, trust deed, or other encumbrance) now or hereafter in force against
all or any part of the Building, or Land.  Upon the request of Landlord, Tenant
will subordinate its rights hereunder to the lien of one or more mortgages
(which term shall include a mortgage, trust deed, and other encumbrance) now or
hereafter in force against all or any part of the Building, or Land and to all
advances made or hereafter to be made upon the security thereof; provided, that
any such mortgage shall provide that the mortgagee, in the event of its
acquiring title to the Building or Land, whether through foreclosure, judicial
process, or otherwise, shall recognize the validity of this lease and shall
honor the rights of Tenant hereunder so long as Tenant (a) is not in default
under this lease at the time such mortgagee acquires such title and (b) agrees
to attorn to such mortgagee as if it were the original Landlord hereunder.

     31.  CUMULATIVE RIGHTS.  The rights, options, elections and
remedies of both parties contained in this lease shall be cumulative and may be
exercised on one or more occasions; and none of them shall be construed as
excluding any other or any additional right, priority, or remedy allowed or
provided by law.

     32.  EMINENT DOMAIN.  If the whole of the Premises shall be taken by any
public authority under the power of eminent domain, then the lease term shall
cease as of the date possession shall be taken by such public authority; and
Tenant shall pay rent up to that date with an appropriate refund by Landlord of
such rent as shall have been paid in advance for a period subsequent to the
date of the taking of possession.  If less than twenty-five percent (25%) of
the floor space of the Premises shall be so taken, then the lease term shall
cease only as to the part taken as of the date possession shall be taken by
such public authority, and Tenant shall pay its full rent up to that day with
an appropriate refund to Tenant of such rent as may have been paid in advance f
or a period subsequent to the date of the taking; and in such event, Landlord
at its expense shall make all necessary repairs and alterations to the Premises
and the Building so as to constitute the remaining premises a complete
architectural unit.  If more than twenty-five percent (25%) of the floor space
of the Premises shall be so taken, then the lease term shall cease only as to
the part so taken from the date possession shall be taken by such public
authority, and Tenant shall pay its full rent up to that day with an
appropriate refund by Landlord of such rent as may have been paid in advance
for a period subsequent to the date of the taking,


                                      9


<PAGE>

except that either party shall have the right to terminate this lease upon 
notice in writing to the other party given within thirty (30) days after such
taking of possession; in the event Tenant remains in possession and Landlord
does not so terminate, then all of the terms herein provided shall continue in
effect except that the Base Rent shall be equitably adjusted, and Landlord
shall make all necessary repairs or alterations to the Premises and the
Building so as to constitute the remaining premises a complete architectural
unit. If more than fifty percent (50%) of the floor space in the Building shall
be taken under the power of eminent domain, either party may, by notice in
writing to the other delivered on or before the day of surrendering possession
to the public authority, terminate this lease; and all rent under this lease
shall be computed to the date of such termination. All compensation awarded for
any taking under the power of eminent domain, whether for the whole or any part
of the Premises, shall be the property of the Landlord, whether such damages be
awarded as compensation for diminution in the value or loss of the leasehold or
for diminution in the value of or loss of the fee of the Premises or
otherwise; and Tenant hereby assigns to Landlord all of Tenant's right, title,
and interest in and to any and all such compensation except for moving costs.

     33.  ADJUSTMENT.  Notwithstanding the foregoing provisions of this
Paragraph 33, if for any calendar year during the term of this Lease, should
real estate taxes, insurance, utilities, maintenance and repairs, and all other
ordinary and necessary expenses (excluding provisions for depreciation and/or
amortization and expenditures of a capital nature) which are the obligations of
the Landlord hereunder, hereafter referred to as operating expenses and which
term specifically excludes any payments of principal or interest on any
purchase money mortgage on the Premises, exceed Two Hundred Seventy-Five
Thousand Dollars ($275,000.00), then the rent for such calendar year shall
automatically be increased by such excess.  Any additional rent required of
Tenant pursuant to the provisions of this paragraph shall be payable within ten
(10) days of demand by landlord, which demand shall be accompanied by an
accounting setting forth the computation of how such additional rent was
determined.

     34.  CONTINUOUS OCCUPANCY. Tenant agrees continuously throughout the term
of this lease to occupy the Premises and to conduct its business therefrom
during all normal business hours, except when the Premises are untenantable by
reason of the occurrence of any damage thereto or the destruction thereof.

     35.  BINDING AGREEMENT. All rights and liabilities herein given to or
imposed upon the respective parties hereto shall extend to and bind the
respective heirs, executors, Administrators, legal representatives, successors,
and assigns of such parties.  No rights, however, shall inure to the benefit of
any assigns of Tenant unless the assignment thereof to such assignee has been


                                      10


<PAGE>

approved by Landlord in writing if such approval is required by this lease.

     36.  ESTOPPEL CERTIFICATES.  Tenant, from time to time upon written 
request from Landlord, agrees to execute, acknowledge, and deliver to 
Landlord, in form reasonably satisfactory to Landlord or Landlord's 
mortgagee, a written statement certifying that Tenant has accepted the 
Premises, that this lease is unmodified and in full force and effect (or, if 
there have been modifications, that this lease is in full force and effect as 
modified, setting forth the modifications), that Landlord is not in default 
hereunder, the date to which the rent and other amounts payable by Tenant 
have been paid in advance (if any), and such additional facts as reasonably 
may be required by Landlord or Landlord's mortgagee.  Tenant understands and 
agrees that any such statement delivered pursuant to this paragraph may be 
relied upon by any prospective purchaser or mortgagee of the Premises and 
their respective successors and assigns.

     37.  GOVERNING LAW.  This lease shall be governed by and construed in
accordance with the laws of the State in which the Premises are located.

     38.  MULTIPLE COUNTERPARTS.  This lease may be executed in multiple
counterparts, each of which shall be deemed to be an original for all purposes.

     39.  DEFINITIONS. Except as otherwise expressly stated in this lease, the
"term" of this lease shall include the original term and any additional term
or extended term, and references to this "lease" shall include this instrument
and any properly executed amendment thereof or supplement thereto.

     40.  NO PERSONAL LIABILITY.  Anything in this lease to the contrary
notwithstanding, Tenant agrees that it will look solely to the equity, estate,
and property of Landlord in the Building, and Land (subject to prior rights of
the holder of any mortgage or deed of trust thereon) for the collection of any
judgment requiring the payment of money by Landlord in the event of any default
on the part of Landlord in the observance or performance of any of the terms,
covenants, and conditions of this lease to be observed or performed by
Landlord; and Tenant understands and agrees that no other assets of Landlord
shall be subject to levy, execution, or other process for the satisfaction of
any such judgment or for the enforcement of any rights or remedies of Tenant.

     41.  SALE OR UNDERLYING LEASE.  In the event of a sale or transfer of the
Building and Land or any undivided interest therein, or in the event of the
making by Landlord of an underlying lease of the Building and Land, the
respective grantor, transferor, or landlord, as the case may be, thereafter
shall be entirely relieved of all obligations to be performed by Landlord under
this lease to the extent of the interest in or portion of the Building,


                                       11


<PAGE>

and Land so sold, transferred, or leased; and, without further agreement
between any of the parties hereto and the purchaser or transferee in the event
of any such sale or transfer, as the case may be, such purchaser, or transferee
shall be deemed to have assumed and agreed to carry out all of the obligations
of Landlord under this lease.  Notwithstanding the foregoing provisions of this
paragraph, the grantor, transferor, or landlord, as the case may be, referred
to in this paragraph shall not be relieved of any liability to Tenant arising
or occurring prior to the sale transfer, or lease referred to herein.

     42.  PARAGRAPH TITLES.  The titles of the various paragraphs of this lease
have been inserted merely as a matter of convenience and for reference only
and shall not be deemed in any manner to define, limit, or describe the scope
or intent of the particular paragraphs to which they refer or to affect the
meaning or construction of the language contained in the body of such
paragraphs.

     43.  SEVERABILITY.  If any provision of this lease shall be declared
legally invalid or unenforceable, then the remaining provisions of this lease
nevertheless shall continue in full force and effect and shall be enforceable
to the fullest extent permitted by law.

     44.  TIME OF ESSENCE.  Time is of the essence of this lease, and all
provisions of this lease relating to the time of performance of any obligation
under this lease shall be strictly construed.

     45.  BROKERS.  Tenant warrants that it had no dealings with any broker or
agent in connection with the negotiations for or execution of this lease other
than Landlord's broker, if any; and Tenant agrees to indemnify Landlord against
and to hold Landlord harmless from any and all cost, expense, or liability for
commissions or other compensation or charges claimed by any other broker or
agent with respect to this lease.

     46.  NUMBER AND GENDER.  Where the context of this lease requires,

                                          TO
                                OFFICE BUILDING LEASE


    THIS AMENDMENT TO OFFICE BUILDING LEASE, made and entered into this 27
day of September, 1996, is an amendment to a certain Office Building Lease dated
July 14, 1993, by and between John Joe and Marlene M. Ricketts, husband and
wife, hereinafter called "Landlord", and TransTerra Co., a Nebraska corporation,
hereinafter called "Tenant".

                                 W I T N E S S E T H:

    WHEREAS, Landlord and Tenant entered into a certain written Office Building
Lease (hereinafter "Lease") wherein Landlord leased unto Tenant and Tenant
leased from Landlord a certain office building and land located at 4211 South
102nd Street, Omaha, Nebraska (hereinafter referred to, as the context may
require, as the "Premises"; the "Building"; and the "Land") as depicted on the
survey attached to the Lease as Exhibit "A"; and

    WHEREAS, Tenant is in need of additional office space and Landlord is
willing to provide such space by constructing as an addition to the Building on
the Land a two-story office building approximately 35,000 square feet in size;
and

    WHEREAS, the parties hereto wish to amend the Lease in the following
hereinafter identified particulars in order that such Lease will incorporate
therein the new two-story office building addition to be constructed by
Landlord.

    NOW, THEREFORE, in consideration of the foregoing preambles which are
incorporated herein and made a part hereof by this reference, and in further
consideration of the mutual covenants of the parties hereto, it is hereby agreed
that said Lease is changed and amended as hereinafter provided:

    1.   TERM.  Paragraph 2 of the Lease is hereby amended to provide for a
term of twenty (20) years commencing on the date Tenant occupies the new
addition (currently estimated as April 1, 1997), plus that additional period
which shall be necessary to enable the term of the lease to end on the last day
of a calendar year.

    2.   BASE RENT.  

    a)   Paragraph No. 3 of the Lease is hereby amended to provide that Tenant
agrees to pay to Landlord, without demand, deduction, or setoff, at Omaha,
Nebraska, or at such other place as Landlord from time to time may designate in
writing, a fixed minimum annual base rent in the amount of One Million Two
Hundred Eighty-eight


<PAGE>
Thousand Dollars ($1,288,000.00), which sum shall be payable by Tenant in 
equal consecutive monthly installments of One Hundred Seven Thousand Three 
Hundred Thirty-three and 33/100 Dollars ($107,333.33) each, in advance, on 
the first day of each month during the term of this Lease.  Rent for any 
period of less than a calendar month shall be pro rated on a daily basis and 
shall be paid within ten (10) days after the end of the period for which it 
is due.

    b)   Anything in the foregoing Paragraph No. 2a) to the contrary
notwithstanding, Landlord and Tenant herewith agree and stipulate that the
above-described rental rate of One Million Two Hundred Eighty-eight Thousand
Dollars ($1,288,000.00) per year (One Hundred Seven Thousand Three Hundred
Thirty-three and 33/100 Dollars ($107,333.33) per month), is predicated upon a
total construction cost for the new addition in the sum of not less than Four
Million Two Hundred Thousand Dollars ($4,200,000.00).  Landlord and Tenant
further agree that said rental rate will be subject to negotiation and
adjustment based on the actual costs of the project.  

    3.   RENTAL ADJUSTMENT.  Paragraph No. 33 of the Lease is hereby amended to
provide that notwithstanding the foregoing provisions of Paragraph 2, supra, if
for any calendar year during the term of this Lease, should real estate taxes,
insurance, utilities, maintenance and repairs, and all other ordinary and
necessary expenses (excluding provisions for depreciation and/or amortization
and expenditures of a capital nature) which are the obligations of the Landlord
hereunder, hereinafter referred to as operating expenses (such term specifically
excluding therefrom any payments of principal or interest on any purchase money
mortgage on the Premises), exceed Five Hundred Forty Thousand Dollars
($540,000.00), then the rent for such calendar year shall automatically be
increased by such excess.  Any additional rent required of Tenant pursuant to
the provision of this paragraph shall be payable within ten (10) days of demand
by Landlord, which demand shall be accompanied by an accounting setting forth
the computation of how such additional rent was determined.

    4.   ENTIRE AGREEMENT.  Paragraph 49 of the Lease is herewith amended to
provide that Tenant and Landlord hereby agree that all of the terms and
provisions of the Lease, except as herein specifically changed and/or amended by
this document, and the exhibits to the Lease therein identified, shall be and
remain in full force and effect, and represent the entire agreement between the
parties hereto with respect to the Premises and that there are no other
agreements, promises, or representations, written or verbal, between the parties
hereto pertaining to the Premises or the subject matter hereof.  This Amendment
to the Lease and the Lease itself may not be further amended or supplemented
orally, but only by an agreement in writing which has been signed by the party
against whom enforcement of any such amendment or supplement is sought.

                                       2

                             ---------                                ----------
    ----------------------------------------------------------------------------
    J.   Refundable Services Retainer   $2,400.00
                                      ------------------------------------------
    ----------------------------------------------------------------------------

    2.   OFFICE.  Client shall, as part of the Base Services, be granted 
a license to use the Office and shall have access to the Office twenty-four 
(24) hours a day, seven (7) days a week. HQ agrees to provide office 
cleaning, maintenance services, electric heating and air conditioning to the 
Office for normal office use in such reasonable quantities and during such 
reasonable hours as shall be determined by HQ or the Building. In addition, 
Client will have reasonable use of HQ common area facilities. Client shall 
use the Office and common areas of the HQ Business Center solely for general 
office use in the conduct of the Client's business.
    If, for any reason whatsoever, HQ is unable to provide use of the Office 
or a mutually agreed upon alternative Office at the time herein agreed, 
Client may either extend the Commencement Date until the Office becomes 
available or, as its sole remedy for such failure, cancel and terminate this 
Agreement if the use of the Office is not available to Client within five (5) 
business days after written notice to HQ by Client, in which case any prior 
payments shall be fully refunded. No such failure to provide use of the 
Office shall subject HQ to any liability for loss or damage, nor affect the 
validity of this Agreement or the obligations of the Client hereunder.
    HQ will have the right to relocate Client to another office in the HQ 
Business Center, and to substitute such other office for the Office licensed 
hereby, provided such other office is substantially similar in area and 
configuration to Client's contracted office and provided Client shall incur 
no increase in the Monthly Base Services Fee or any relocation cost or 
expense.
    3.   SERVICES.  HQ agrees, in consideration of the Monthly Base Services 
Fee, to provide Base Services to Client as described in Schedule "A". From 
time to time during the Term, HQ may, at its option, make other services 
available to Client of the nature described in Schedule "B", at fees that are 
from time to time established by HQ. HQ shall be under no obligation to 
provide Schedule "B" services if the monthly cost thereof exceeds the 
Refundable Services Retainer. In the event Client is in default of this 
Agreement, HQ may, at its option, cease furnishing any and all services 
including telephone services.
    Client will not offer to any party in the HQ Business Center or the 
Building, any of the services that HQ provides to its clients including, but 
not limited to, the services described in Schedule "A" or "B".
    HQ will answer all incoming telephone calls, unless otherwise mutually 
agreed, during normal business hours, as determined by HQ. Answering service 
will be limited to normal business communications, excluding inbound 
telemarketing and advertising response which requires pre-approval by HQ and 
shall be subject to fees established from time to time by HQ.
    Client will use only telecommunications systems and services as provided 
by HQ. Client will pay to HQ a monthly equipment rental fee for the use of 
each telephone instrument and voice lines. In the event HQ discontinues the 
offering of long distance service, Client will provide its own long distance 
service through a locally accessed long distance carrier.
    Client acknowledges that due to the imperfect nature of verbal, written 
and electronic communications, neither HQ nor any of its officers, directors, 
employees, shareholders, partners, agents or representatives shall be 
responsible for damages, direct or consequential, that may result from


995HQBC                         Page 1 of 5   -C- 1995 HQ NETWORK SYSTEMS, INC.

<PAGE>

the failure of HQ to furnish any service, including but not limited to the 
service of conveying messages, communications and other utility or services 
required under this Agreement or agreed to by HQ. Client's sole remedy and 
HQ's sole obligation for any failure to render any service, any error or 
omission, or any delay or interruption with respect thereto, is limited to an 
adjustment to Client's billing in an amount equal to the charge for such 
service for the period during which the failure, delay or interruption 
continues.
    CLIENT EXPRESSLY WAIVES, AND AGREES NOT TO MAKE ANY CLAIM FOR DAMAGES, 
DIRECT OR CONSEQUENTIAL, ARISING OUT OF ANY FAILURE TO FURNISH ANY UTILITY, 
SERVICE OR FACILITY, ANY ERROR OR OMISSION WITH RESPECT THERETO, OR ANY 
DELAY OR INTERRUPTION OF THE SAME.
    4.   DURATION OF AGREEMENT.  Upon the End of Initial Term, or any 
extension thereof, the term of this Agreement and the license herein granted 
shall be automatically extended for the same period of time as the Initial 
Term, upon the same terms and conditions as contained herein, unless either 
party gives notice to the other in writing to the contrary at least sixty 
(60) days prior to the End of Initial Term (90 days if Client has licensed 
the use of three or more offices). 
    Upon any termination of this Agreement, whether by lapse of time or 
otherwise, or upon any revocation of Client's license herein granted, the 
Client shall cease all use of the Office, the HQ Business Center and all 
services immediately. For each and every month or portion thereof that Client 
continues use of the Office after the termination of this Agreement by lapse 
of time or otherwise, without the express written consent of HQ, Client shall 
pay HQ an amount equal to double the Monthly Base Services Fee computed on a 
per-month basis for each month or portion thereof that Client continues the 
use of the Office.
    5.   PAYMENTS AND ESCALATIONS.  Client agrees to pay to HQ the Monthly 
Base Services Fee plus applicable sales or use taxes, in advance, on the 
first day of each calendar month during the Initial Term and all extensions 
thereof, without any deduction, offset, notice or demand. If the Commencement 
Date shall be other than the first day of a month or end on the last day of a 
month, fees for any such month shall be prorated. Charges for any Schedule 
"B" service purchased by Client from HQ shall be due and payable on the 10th 
of the month following the order for any such service.
    One year after the Commencement Date of this Agreement and each and every 
anniversary date thereafter, the Monthly Base Services Fee will automatically 
increase by six percent (6%) of the Monthly Base Services Fee due for the 
month preceding such anniversary date.
    All Monthly Base Services Fees and other sums payable hereunder shall be 
payable at the office of HQ or at such other location or to any agent 
designated in writing by HQ. In addition to any other sums due, Client shall 
pay monthly late charges equal to five percent (5%) of all amounts that have 
not been paid to HQ within five (5) days of their respective due dates. The 
parties agree that such late charges are fair and reasonable compensation for 
costs incurred by HQ where there is default in any payment due under this 
Agreement.
    Upon the execution of this Agreement, Client shall pay HQ or its agent 
the Refundable Services Retainer. The Refundable Services Retainer need not 
be kept separate and apart from other funds of HQ, no interest shall be paid 
thereon, and may be used by HQ to provide Schedule "A" and "B" services under 
this Agreement. In addition to the Refundable Services Retainer, Client will, 
upon execution hereof, pay to HQ the Monthly Base Services Fee for the first 
full month of the Initial Term.
    Client agrees that the Refundable Services Retainer shall not be used by 
Client as payment for the Monthly Base Services Fee for the last month of the 
Initial Term, or any extension thereof. In the event Client defaults in the 
performance of any of the terms hereof, HQ may terminate this Agreement and 
the license herein granted and may also use, apply or retain the whole, or 
any part, of the Refundable Services Retainer for the payment of any service 
fee or any other payment due hereunder, or for payment of any other sum that 
HQ may spend by reason of Client's default. If Client shall, at the end of 
the term of this Agreement, have fully and faithfully complied with all of 
the terms and provisions of this Agreement, and surrendered all keys, access 
cards and building passes, the Refundable Services Retainer, or any balance 
thereof, shall be returned to Client within forty-five (45) days thereafter.
    6.   DAMAGES AND INSURANCE.  Client will not damage or deface the 
furnishings, walls, floors or ceilings, nor make holes for the hanging of 
pictures or make or suffer to be made any waste, obstruction or unlawful, 
improper or offensive use of the Office or the common area facilities. Client 
will not cause damage to any part of the Building or the property of HQ or 
disturb the quiet enjoyment of any other licensee or occupant of the 
Building. At the termination of this Agreement, the Office shall be in as 
good condition as when Client commenced the use thereof, normal wear and tear 
excepted. Client agrees to pay for repainting each Office used less than 
twelve (12) months by Client, at a cost not to exceed One Hundred Fifty 
Dollars ($200.00) per Office. HQ will have the right, at any time and from 
time to time, to enter the Office to inspect the same, to make such repairs 
and alterations as HQ reasonably deems necessary, and the cost of any such 
repair resulting from the act or omission of Client shall be reimbursed to 
HQ by Client upon demand. HQ shall have the right to show the Office to 
prospective Clients, provided HQ will use reasonable efforts not to disrupt 
Client's business.
    HQ and its respective directors, licensors, officers, agents, servants 
and employees shall not, to the extent permitted by law, except upon the 
affirmative showing of HQ's gross negligence or willful misconduct, be 
liable for, and Client waives all right of recovery against such entities and 
individuals for any damage or claim with respect to any injury to person or 
damage to, or loss or destruction of any property of Client, its employees, 
authorized persons and invitees due to any act, omission or occurrence in or 
about the HQ Business Center or the Building. Without limitation of any other 
provision hereof, each party hereto hereby agrees to indemnify, defend and 
hold harmless the other party hereto, and such other party's officers, 
directors, employees, shareholders, partners, agents and representatives from 
and against any liability to third parties arising out of, in the case of 
Client as an indemnifying party, Client's use and occupancy of the Office or 
any negligent act or omission of Client or Client's officers, directors, 
employees, shareholders, partners, agents, representatives, contractors, 
customers or invitees and, in the case of HQ as an indemnifying party, any 
act or omission constituting gross negligence or willful misconduct of HQ or 
HQ's officers, directors, employees, shareholders, partners, agents or 
representatives. Subject to the foregoing, Client assumes all risk of loss 
with respect to all personal property of Client, its agents employees, 
contractors, and invitees, within or about the HQ Business Center or the 
Building. Client acknowledges that it is the Client's responsibility to 
maintain insurance to cover the risks set forth in this paragraph.
    HQ and Client each hereby waive any and all rights of recovery against 
the other, or against the directors, licensors, officers, agents, servants 
and employees of the other, for loss of or damage to its property or the 
property of others under its control, to the extent such loss or damage is 
covered by any insurance policy.
    If the HQ Business Center is made unusable, in whole or in part, by fire 
or other casualty not due to negligence of Client, HQ may, at its option, 
terminate the Agreement upon notice to Client, effective upon such casualty, 
or may elect to repair, restore or rehabilitate, or cause to be repaired, 
restored or rehabilitated, the HQ Business Center, without expense to


                                 Page 2 of 5
<PAGE>

Client, within ninety (90) days or within such longer period of time as may 
be required because of events beyond HQ's control. The Monthly Base Services 
Fee shall be abated on a per diem basis for the portions of the Office that 
are unusable. 
    7. DEFAULT.  Client shall be deemed to be in default under this 
Agreement: (a) if Client defaults in the payment of the Monthly Base Services 
Fee or other sums due hereunder or (b) if Client defaults in the prompt and 
full performance of any other provision of this Agreement and any such 
default continues in excess of five (5) business days after written notice by 
HQ. 
    Should Client be in default hereunder, HQ shall have the option to pursue 
any one or more of the following remedies without any additional notice or 
demand whatsoever and without limitation to HQ in the exercise of any remedy: 
    (1) HQ may, if HQ so elects, without any additional notice of such 
election or demand to Client, either forthwith terminate this Agreement and 
the license to use any portion of the HQ Business Center, and may enter into 
the Office and take and hold possession of the contents thereof, without 
releasing Client, in whole or in part, from the Client's obligations 
hereunder. In the event of such termination, HQ may, at its option, declare 
the entire amount of the Monthly Base Services Fee which would become due and 
payable during the remainder of the term, to be due and payable immediately, 
in which event, Client agrees to pay the same at once.
    (2) Pursue any other remedy now or hereafter available to HQ. HQ's 
exercise of any right or remedy shall not prevent it from exercising any 
other right or remedy.
    Client agrees to pay all costs and expenses, including reasonable 
attorneys' fees, expended or incurred by HQ in connection with the 
enforcement of this Agreement, the collection of any sums due hereunder, any 
action for declaratory relief in any way related to this Agreement, or the 
protection or preservation of any rights of HQ hereunder.
    8.   RESTRICTION ON HIRING.  Client agrees that during the term of this 
Agreement and within one (1) year of the termination of this Agreement, 
neither Client nor any of its principals, employees or affiliates will hire 
directly or as an independent contractor, any person who is at that time, or 
was during the term of this Agreement, an employee of HQ. In the event of a 
breach of any obligation of Client contained in this paragraph, Client shall 
be liable to HQ for, and shall pay to HQ, on demand, liquidated damages in 
the sum of $10,000.00 for each employee with respect to whom such breach shall 
occur, it being mutually agreed that the actual damage that would be 
sustained by HQ as the result of any such breach would be, from the nature of 
the case, extremely difficult to fix and that the aforesaid liquidated 
damage amount is fair and reasonable.
    9.   MISCELLANEOUS. 
    A.  This is the only Agreement between the parties. No other agreements 
are effective. All amendments to this Agreement shall be in writing and 
signed by all parties. Any other attempted amendment shall be void. The 
invalidity or unenforceability of any provision hereof shall not affect the 
remainder hereof.
    B.  All waivers must be in writing and signed by the waiving party. HQ's 
failure to enforce any provision of this Agreement or its acceptance of fees 
shall not be a waiver and shall not prevent HQ from enforcing any provision 
of this Agreement in the future. No receipt of money by HQ shall be deemed to 
waive any default of Client or to extend, reinstate or continue the term 
hereof.
    C.  All Schedules and Addenda attached hereto are hereby incorporated 
herein by this reference. The laws of the State in which the HQ Business 
Center is located shall govern this Agreement.
    D.  All parties signing this Agreement as a partnership or co-signing 
individuals shall be jointly and severally liable for all obligations of 
Client.
    E.  Client represents and warrants to HQ that there are no agents, 
brokers, finders or other parties except ____________________ with whom 
Client has dealt who are or may be entitled to any commission or fee with 
respect to this Agreement.
    F.   Neither Client nor anyone claiming by, through or under Client 
shall assign this Agreement or permit the use of any portion of the HQ 
Business Center by any person other than Client; provided, however, Client 
may assign this Agreement to an affiliated corporation of Client. In the 
event of any such permitted assignment, Client shall not thereby be relieved 
of any of its obligations under this Agreement.
    G.   The Rules and Regulations of the Building and of HQ as defined on 
Schedule "C" hereto and any additional schedules that may be attached hereto 
are expressly made a part of this Agreement and Client expressly covenants 
and agrees to abide by all of such Rules and Regulations and such additional 
terms, as well as such reasonable modifications to such Rules and Regulations 
as may be hereafter adopted by HQ.
    H.   All notices hereunder shall be in writing. Notices to Client shall 
be deemed to be duly given if mailed by registered or certified mail, postage 
prepaid, addressed to Client at:

    I.   THIS AGREEMENT IS NOT INTENDED TO CREATE A LEASE OR ANY OTHER 
INTEREST IN REAL PROPERTY IN FAVOR OF THE CLIENT, BUT MERELY CREATES A 
REVOCABLE LICENSE IN ACCORDANCE WITH THE TERMS HEREOF.  This Agreement grants 
Client the license to use the HQ Business Center and the Office for the 
specific purposes herein set forth without diminution of the legal possession 
or control thereof by HQ and shall be revocable at the option of HQ upon the 
destruction of the HQ Business Center or the breach by Client of any term or 
condition herein set forth. This Agreement is subject and subordinate to any 
underlying lease or contract of the Building or of the premises comprising 
the Office or the HQ Business Center as such lease or contract may be amended 
from time to time (such underlying lease or contract together with any 
amendments, is hereinafter referred to as the "Master Lease"). This Agreement 
shall terminate simultaneously with the termination of the HQ Business Center 
operation for any reason. Client is not a party to nor shall Client have any 
rights under the Master Lease.

creditors;
    (d) If involuntary proceedings under any bankruptcy or insolvency act 
shall be instituted against Tenant, or if a receiver or trustee shall be 
appointed of all or substantially all of the property of Tenant, and such

addition to Tenant's liability to Landlord for breach of this Lease, Tenant 
shall be liable for all expenses of the reletting, for any alterations and 
repairs made, and for the rent due for the balance of the Lease term, which 
sum shall be immediately due Landlord from Tenant. The amount due Landlord 
will be reduced by the net rent received by Landlord during the remaining term
of this Lease from reletting the Premises or any part thereof. If during the 
remaining term of this Lease Landlord receives more than the amount due 
Landlord under this sub-paragraph, the Landlord shall pay such excess to 
Tenant, but only to the extent Tenant, but only to the extent Tenant has 
actually made payment pursuant to this sub-paragraph.

                           SURRENDER - HOLDING OVER     19. Tenant shall, 
upon termination of this Lease, whether by lapse of time or otherwise 
peaceably and promptly surrender the Premises to Landlord. If Tenant remains 
in possession after the termination of this Lease, without a written lease 
duly executed by the parties, Tenant shall be deemed a trespasser. If Tenant 
pays, and Landlord accepts, rent for a period after termination of this 
Lease, Tenant shall be deemed to be occupying the Premises only as a tenant 
from month to month, subject to all the terms, conditions, and agreements of 
this Lease, except that the rent shall be two times the monthly rent 
specified in the lease immediately before termination.

                       SUBORDINATION AND ATTORNMENT
    20. Landlord reserves the right to place liens and encumbrances on the 
Premises superior in lien and effect to this Lease. This Lease, and all 
rights of Tenant hereunder, shall, at the option of Landlord, be subject and 
subordinate to any liens and encumbrances now or hereafter imposed by 
Landlord upon the Premises or the Real Estate or any part thereof, and Tenant 
agrees to execute, acknowledge, and deliver to Landlord, upon request, any 
and all instruments that may be necessary or proper to subordinate this Lease 
and all rights herein to any such lien or encumbrance as may be required by 
Landlord.

     In the event any proceedings are brought for the foreclosure of any 
mortgage on the Premises, Tenant will attorn to the purchaser at the 
foreclosure sale and recognize such purchaser as the Landlord under this 
Lease. The purchaser, by virtue of such foreclosure, shall be deemed to have 
assumed, as substitute Landlord, the terms and conditions of this Lease until 
the resale or other disposition of its interest. Such assumption, however, 
shall not be deemed an acknowledgment by the purchaser of the validity of any 
then existing claims of Tenant against the prior Landlord.

     Tenant agrees to execute and deliver such further assurances and other 
documents, including a new lease upon the same terms and conditions contained 
herein, confirming the foregoing, as such purchaser may reasonably request. 
Tenant waives any right of election to terminate this Lease because of any 
such foreclosure proceedings.

                                 NOTICES
     21. Any notice to given hereunder shall be given in writing and sent by 
registered or certified mail to Landlord at 404 So. 108th St., Omaha, NE 
68157 and to Tenant at TransTerra Co., Attn: Thomas J. Pleiss, Vice 
President, 4211 So. 102nd St., Omaha, NE 68127 or at such other address as 
either party may from time to time designate in writing. Each such notice 
shall be deemed to have been given at the time it shall be personally 
delivered to such address or deposited in the United States mail in the 
manner prescribed herein.

                                 NET LEASE
     22. This is a net-net-net Lease and the parties agree and understand 
that Tenant shall pay Tenant's proportionate share of the real estate taxes, 
special assessments, insurance and all other Operating Expense as described 
in subparagraph 4.b of this Lease.

                               MISCELLANEOUS
     23. (a) BINDING ON ASSIGNS. All terms, conditions, and agreements of 
this Lease shall be binding upon, apply, and inure to the benefit of the 
parties hereto and their respective heirs, representatives, successors, and 
assigns.

     (b) AMENDMENT IN WRITING. This Lease contains the entire agreement 
between the parties and may be amended only by subsequent written agreement.

     (c) WAIVER - NONE. The failure of Landlord to insist upon strict 
performance of any of the terms, conditions and agreements of this Lease 
shall not be deemed a waiver of any of its rights or remedies hereunder and 
shall not be deemed a waiver of any subsequent breach or default of any of 
such terms, conditions, and agreements. The doing of anything by Landlord 
which Landlord is not obligated to do hereunder shall not impose any future 
obligation on Landlord nor otherwise amend any provisions of this Lease.

     (d) NO SURRENDER. No surrender of the Premises by Tenant shall be 
effected by Landlord's acceptance of the keys to the Premises or of the rent 
due hereunder, or by any other means whatsoever, without Landlord's written 
acknowledgment that such acceptance constitutes a surrender.

     (e) CAPTIONS. The captions of the various paragraphs in this Lease are 
for convenience only and do not define, limit, describe, or construe the 
contents of such paragraphs.

     (f) BROKERS. Landlord hereby warrants that N P Dodge Management Company 
is the Real Estate Broker in this transaction and that Landlord has agreed to 
pay a real estate fee to said Broker.

     (g) APPLICABLE LAW. This Lease shall be governed by and construed in 
accordance with the laws of the State of Nebraska.


                                 OTHER PROVISIONS

     24.  1. This Lease agreement will be null and void in the event that the

                                 EMPLOYMENT AGREEMENT


    This Agreement made and entered into as of the 3rd day of December, 1996
(the "Effective Date") by and between Ameritrade Holding Corporation (the
"Company"), and J. Joe Ricketts (the "Executive"),

                                   WITNESSETH THAT:

    WHEREAS, the parties desire to enter into this Agreement pertaining to the
continued employment of the Executive by the Company; 

    NOW THEREFORE, in consideration of the mutual covenants and agreements set
forth below, it is hereby covenanted and agreed by the Company and the Executive
as follows: 

    1.   EMPLOYMENT PERIOD.  Subject to the terms of this Agreement, the
Company hereby agrees to employ the Executive as its Chairman and Chief
Executive Officer during the Employment Period (as defined below), and the
Executive hereby agrees to remain in the employ of the Company during the
Employment Period and to provide services during the Employment Period in
accordance with this Agreement.  The "Employment Period" shall be the period
beginning on the Effective Date and ending on the first anniversary thereof. 
After the first anniversary of the Effective Date, the Employment Period shall
be automatically extended for three additional consecutive 12-month periods,
unless one party to this Agreement provides written notice of non-renewal to the
other at least 180 days before the last day of the then current Employment
Period. 

    2.   DUTIES.  The Executive agrees that, during the Employment Period while
he is employed by the Company, he will devote his full time, energies and
talents to serving as the Chairman and the Chief Executive Officer of the
Company, subject to the direction of the Board of Directors of the Company (the
"Board").  The Executive shall have such duties and responsibilities as may be
assigned to him from time to time by the Board, including, but not limited to,
managing and directing the operations, executives and markets of the
subsidiaries of the Company, creating and executing strategic business plans to
enable the accomplishment of corporate goals, evaluating profitable corporate
purchases and marketing Company services to the industry.  The Executive shall
perform all duties assigned to him faithfully and efficiently, subject to the
direction of the Board and shall have such authorities and powers as are
inherent 

<PAGE>


to the undertakings applicable to his position and necessary to carry out the
responsibilities and duties required of him hereunder; provided, however, that
the Executive shall not be required to perform any duties while he is disabled
(within the meaning of paragraph 4(c)).  Notwithstanding the foregoing
provisions of this Section 2, during the Employment Period, the Executive may
devote reasonable time to activities other than those required under this
Agreement, including the supervision of his personal investments, and activities
involving professional, charitable, educational, religious and similar types of
organizations, speaking engagements, membership on the boards of directors of
other organizations, and similar type activities, to the extent that such other
activities do not, in the judgement of the Board, inhibit or prohibit the
performance of the Executive's duties under this Agreement, or compete or
conflict with the business of the Company or any of its subsidiaries.
 
    3.   COMPENSATION.  Subject to the terms and conditions of this Agreement,
during the Employment Period while the Executive is employed by the Company, the
Company shall compensate him for his services as follows:

    (a)  The Executive shall receive, for each 12-consecutive month period
         beginning on the Effective Date and each anniversary thereof, an
         annual salary of $350,000 (the "Salary"), which Salary shall be
         payable in substantially equal monthly or more frequent installments. 
         The Executive's Salary rate shall be reviewed annually on or about
         January 1 of each year; provided, however, that in no event shall the
         Salary of the Executive be reduced to an amount that is less than the
         amount specified in this paragraph (a) (as the same may be increased
         from time to time) except to the extent that reductions of the same
         percentage are being made at the same time to the salaries of all
         other senior executive officers of the Company. 

    (b)  The Executive shall be entitled to receive bonuses from the Company as
         determined in the sole discretion of the Board.

    (c)  Except as otherwise specifically provided to the contrary in this
         Agreement, the Executive shall be provided with the employee benefits
         and other fringe benefits and perquisites to the same extent and on
         the same terms and conditions as those benefits are provided by the
         Company from time to time to the Company's other senior executive
         officers.

    4.   RIGHTS AND PAYMENTS UPON TERMINATION.  The Executive's employment with
the Company may be terminated during the 


                                         -2-

<PAGE>


Employment Period by the Company or the Executive at any time, for any reason,
without breach of this Agreement.  The Executive's right to benefits and
payments, if any, for periods after the date on which his employment with the
Company terminates for any reason (his "Termination Date") shall be determined
in accordance with the following provisions of this Section 4:

    (a)  MINIMUM PAYMENTS.  If the Executive's Termination Date occurs during
         the Employment Period for any reason, the employee shall be entitled
         to the following payments, in addition to any payments or benefits to
         which the Executive may be entitled under the following provisions of
         this Section 4 (other than this paragraph (a)) and the express terms
         of any employee benefit plan or arrangement in which the Executive
         participates as of his Termination Date:

         (i)       his earned but unpaid Salary for the period ending on his
                   Termination Date; and
 
         (ii)      his accrued but unpaid vacation pay for the period ending
                   with his Termination Date, as determined in accordance with
                   the Company's policy as in effect from time to time.

         Payments to be made to the Executive pursuant to this paragraph 4(a)
         shall be made in a lump sum as soon as practicable after the
         Executive's Termination Date.  Except as may be otherwise expressly
         provided to the contrary in this Agreement, nothing in this Agreement
         shall be construed as requiring the Executive to be treated as
         employed by the Company following his Termination Date for purposes of
         any employee benefit plan or arrangement in which he may participate
         at such time.

    (b)  TERMINATION BY COMPANY FOR CAUSE.  If the Executive's Termination Date
         occurs during the Employment Period and is a result of the Company's
         termination of the Executive's employment on account of Cause (as
         defined below), then, except as agreed in writing between the
         Executive and the Company, the Executive shall have no right to future
         payments or benefits under this Agreement (and the Company shall have
         no obligation to make any such future payments or provide any such
         future benefits) for periods after the Executive's Termination Date. 
         For purposes of this Agreement, the term "Cause" shall mean (1) the
         continuous failure by the Executive to substantially perform his
         duties under this Agreement, (2) the willful engaging by the 


                                         -3-

<PAGE>


         Executive in conduct which is demonstrably and materially injurious to
         the Company or its affiliates, monetarily or otherwise, (3) conduct by
         the Executive that involves theft, fraud or dishonesty, or (4) the
         Executive's violation of the provisions of Section 6 hereof.

    (c)  TERMINATION FOR DEATH OR DISABILITY.  If the Executive's Termination
         Date occurs during the Employment Period on account of the Executive's
         death or disability (as defined below), then the Executive (or in the
         event of his death, his estate) shall be entitled to continuing
         payments of his Salary for the period commencing on his Termination
         Date and ending on the earliest of (i) the last day of the calendar
         month in which his Termination Date occurs, (ii) the last day of the
         Employment Period, or (iii) the date on which the Executive violates
         the provisions of Section 6 of this Agreement.   For purposes of this
         Agreement, the term "disability" shall mean the inability of the
         Executive to continue to perform his duties under this Agreement on a
         full-time basis as a result of mental or physical illness, sickness or
         injury for a period of 90 days within any 12-month period, as
         determined in the sole discretion of the Board. 

    (d)  TERMINATION BY THE COMPANY FOR REASONS OTHER THAN CAUSE.  If the
         Executive's Termination Date occurs during the Employment Period and
         is a result of the Executive's termination of employment by the
         Company for any reason other than Cause (and is not on account of the
         Executive's death, disability, or voluntary resignation, the mutual
         agreement of the parties or any other reason), then the Executive
         shall receive from the Company for the period commencing on his
         Termination Date and ending on the earliest of (i) last day of the
         Employment Period, (ii) the six month anniversary of his Termination
         Date, (iii) the date on which the Executive violates the provisions of
         Section 6 of this Agreement, or (iv) the date of the Executive's
         death, the Salary in effect as of his Termination Date, payable in
         accordance with the provisions of paragraph 3(a).  Notwithstanding the
         foregoing, the Company may, at any time, relieve the Executive of his
         duties for a specified period of time and such action on the part of
         the Company shall not be considered a termination of the Executive's
         employment hereunder.  During any period that the Executive has been
         relieved of his duties pursuant to the foregoing sentence, all
         provisions of this Agreement, other than the provisions of Section 2
         which require the Executive 


                                         -4-

<PAGE>


         to actively perform services for the Company, shall continue to remain
         in full force and effect.

    (e)  TERMINATION FOR VOLUNTARY RESIGNATION, MUTUAL AGREEMENT OR OTHER
         REASONS.  If the Executive's Termination Date occurs during the
         Employment Period on account of his voluntary resignation, mutual
         agreement of the parties, or any reason other than those specified in
         paragraphs (b), (c) or (d) above then, except as agreed in writing
         between the Executive and the Company, the Executive shall have no
         right to future payments or benefits under this Agreement (and the
         Company shall have no obligation to make any such future payments or
         provide any such future benefits) for periods after the Executive's
         Termination Date.  

    (f)  NOTICE OF NON-RENEWAL.  If the Executive's Termination Date occurs at
         the end of the Employment Period on account of non-renewal of the
         Employment Period by either party in accordance with Section 1, then,
         except as agreed in writing between the Executive and the Company, the
         Executive shall have no right to future payments or benefits under
         this Agreement (and the Company shall have no obligation to make any
         such future payments or provide any such future benefits) for periods
         after the Executive's Termination Date.  

Notwithstanding any other provision of this Agreement, the Executive shall
automatically cease to be an officer and/or director of the Company and its
affiliates as of his Termination Date.  

    5.   SET-OFF.  The Company shall be entitled to set off against the amounts
payable to the Executive under this Agreement, any amounts owed to the Company
or its affiliates by the Executive.

    6.   CONFIDENTIAL INFORMATION.  The Executive agrees that:

    (a)  Except as may be required by the lawful order of a court or agency of
         competent jurisdiction, or except to the extent that the Executive has
         express authorization from the Company, he shall keep secret and
         confidential indefinitely all non-public information (including,
         without limitation, information regarding costs of new accounts,
         activity rates of different market niche customers and advertising
         results) concerning the Company and the subsidiaries which was
         acquired by or disclosed to the Executive during the course of his
         employment with the Company and not to disclose the same, either
         directly or indirectly, to any other 


                                         -5-

<PAGE>


         person, firm, or business entity, or to use it in any way.  

    (b)  Upon his Termination Date or at the Company's earlier request, he will
         promptly return to the Company any and all records, documents,
         physical property, information, computer disks or other materials
         relating to the business of the Company and its affiliates obtained by
         him during his course of employment with the Company.

    (c)  The Executive shall keep the Company informed of, and shall execute
         such assignments as may be necessary to transfer to the Company or its
         affiliates the benefits of, any inventions, discoveries, improvements,
         trade secrets, developments, processes, and procedures made by the
         Executive, in whole or in part, or conceived by the Executive either
         alone or with others, which result from any work which the Executive
         may do for or at the request of the Company, whether or not conceived
         by the Executive while on holiday, on vacation, or off the premises of
         the Company, including such of the foregoing items conceived during
         the course of employment which are developed or perfected after the
         Executive's termination of employment.  The Executive shall assist the
         Company or other nominated by it, to obtain patents, trademarks and
         service marks and the Executive agrees to execute all documents and to
         take all other actions which are necessary or appropriate to secure to
         the Company and its affiliates the benefits thereof.  Such patents,
         trademarks and service marks shall become the property of the Company
         and its affiliates.  The Executive shall deliver to the Company all
         sketches, drawings, models, figures, plans, outlines, descriptions or
         other information with respect thereto.
    
    (d)  To the extent that any court or agency seeks to have the Executive
         disclose confidential information, he shall promptly inform the
         Company, and he shall take such reasonable steps to prevent disclosure
         of Confidential Information until the Company has been informed of
         such requested disclosure, and the Company has an opportunity to
         respond to such court or agency.  To the extent that the Executive
         obtains information on behalf of the Company or any of the
         subsidiaries that may be subject to attorney-client privilege as to
         the Company's attorneys, the Executive shall take reasonable steps to
         maintain the confidentiality of such information and to preserve such
         privilege.  


                                         -6-

<PAGE>


    (e)  Nothing in the foregoing provisions of this Section 6 shall be
         construed so as to prevent the Executive from using, in connection
         with his employment for himself or an employer other than the Company
         or any of its affiliates, knowledge which was acquired by him during
         the course of his employment with the Company and its affiliates, and
         which is generally known to persons of his experience in other
         companies in the same industry.

    7.   EQUITABLE REMEDIES.  The Executive acknowledges that the Company would
be irreparably injured by a violation of Section 6 and agrees that the Company,
in addition to other remedies available to it for such breach or threatened
breach, shall be entitled to a preliminary injunction, temporary restraining
order, other equivalent relief, restraining the Executive from any actual or
threatened breach of Section 6 without any bond or other security being
required.

    8.   DEFENSE OF CLAIMS.  The Executive agrees that, on and after the
Effective Date, he will cooperate with the Company and its affiliates in the
defense of any claims that may be made against the Company or its affiliates to
the extent that such claims may relate to services performed by him for the
Company. To the extent travel is required to comply with the requirements of
this Section 9, the Company, shall to the extent possible, provide the Executive
with notice at least 10 days prior to the date on which such travel would be
required and the Company agrees to reimburse the Executive for all of his
reasonable actual expenses associated with such travel; provided, however, that
if the Company reasonably expects the travel to be extensive or unduly
burdensome to the Executive from a financial perspective, the Executive may
provide to the Executive pre-paid tickets for transportation in connection with
such travel.

                              EMPLOYMENT AGREEMENT


     This Agreement made and entered into as of the 3rd day of December, 1996
(the "Effective Date") by and between Ameritrade Holding Corporation (the
"Company"), and Joseph A. Konen (the "Executive"),

                                WITNESSETH THAT:

     WHEREAS, the parties desire to enter into this Agreement pertaining to the
continued employment of the Executive by the Company;

     NOW THEREFORE, in consideration of the mutual covenants and agreements set
forth below, it is hereby covenanted and agreed by the Company and the Executive
as follows:

   1.   EMPLOYMENT PERIOD.  Subject to the terms of this Agreement, the Company
hereby agrees to employ the Executive as its President and Chief Operating
Officer during the Employment Period (as defined below), and the Executive
hereby agrees to remain in the employ of the Company during the Employment
Period and to provide services during the Employment Period in accordance with
this Agreement.  The "Employment Period" shall be the period beginning on the
Effective Date and ending on the first anniversary thereof.  After the first
anniversary of the Effective Date, the Employment Period shall be automatically
extended for three additional consecutive 12-month periods, unless one party to
this Agreement provides written notice of non-renewal to the other at least 180
days before the last day of the then current Employment Period.

     2.  DUTIES.  The Executive agrees that, during the Employment Period while
he is employed by the Company, he will devote his full time, energies and
talents to serving as the President and Chief Operation Officer of the Company,
subject to the direction of the Chairman and Chief Executive Officer of the
Company (the "CEO").  The Executive shall have such duties and responsibilities
as may be assigned to him from time to time by the CEO, including, but not
limited to, directing the activities of the subsidiaries of the Company relating
to their organizational, service, and administrative functions, managing and
mentoring the general managers and presidents of the subsidiaries and the vice
president of human resources of the Company and assisting the CEO in creating
and directing short and long term growth and profitability of the Company.  The
Executive shall perform all duties assigned to him faithfully and




<PAGE>

efficiently, subject to the direction of the CEO and shall have such authorities
and powers as are inherent to the undertakings applicable to his position and
necessary to carry out the responsibilities and duties required of him
hereunder; provided, however, that the Executive shall not be required to
perform any duties while he is disabled (within the meaning of paragraph 4(c)).
Notwithstanding the foregoing provisions of this Section 2, during the
Employment Period, the Executive may devote reasonable time to activities other
than those required under this Agreement, including the supervision of his
personal investments, and activities involving professional, charitable,
educational, religious and similar types of organizations, speaking engagements,
membership on the boards of directors of other organizations, and similar type
activities, to the extent that such other activities do not, in the judgement of
the CEO, inhibit or prohibit the performance of the Executive's duties under
this Agreement, or compete or conflict with the business of the Company or any
of its subsidiaries.

    3.  COMPENSATION.  Subject to the terms and conditions of this Agreement,
during the Employment Period while the Executive is employed by the Company, the
Company shall compensate him for his services as follows:

     (a)  The Executive shall receive, for each 12-consecutive month period
          beginning on the Effective Date and each anniversary thereof, an
          annual salary of $300,000 (the "Salary"), which Salary shall be
          payable in substantially equal monthly or more frequent installments.
          The Executive's Salary rate shall be reviewed annually on or about
          January 1 of each year; provided, however, that in no event shall the
          Salary of the Executive be reduced to an amount that is less than the
          amount specified in this paragraph (a) (as the same may be increased
          from time to time) except to the extent that reductions of the same
          percentage are being made at the same time to the salaries of all
          other senior executive officers of the Company.

     (b)  The Executive shall be entitled to receive bonuses from the Company as
          determined in the sole discretion of the Board of Directors of the
          Company.

     (c)  Except as otherwise specifically provided to the contrary in this
          Agreement, the Executive shall be provided with the employee benefits
          and other fringe benefits and perquisites to the same extent and on
          the same terms and conditions as those benefits are provided by the
          Company from time to time to the Company's other senior executive
          officers.

     4.   RIGHTS AND PAYMENTS UPON TERMINATION.  The Executive's employment with
the Company may be terminated during the Employment Period by the Company or the
Executive at any time, for any reason, without breach of this Agreement.  The
Executive's right to benefits and payments, if any, for periods after the date
on which his employment with the Company terminates for any reason (his
"Termination Date") shall be determined in accordance with the following
provisions of this Section 4:

     (a)  MINIMUM PAYMENTS.  If the Executive's Termination Date occurs during
          the Employment Period for any reason, the employee shall be entitled
          to the following payments, in addition to any payments or benefits to
          which the Executive may be entitled under the following provisions of
          this Section 4 (other than this paragraph (a)) and the express terms
          of any employee benefit plan or arrangement in which the Executive
          participates as of his Termination Date:

          (i)       his earned but unpaid Salary for the period ending on his
                    Termination Date; and

          (ii)      his accrued but unpaid vacation pay for the period ending
                    with his Termination Date, as determined in accordance with
                    the Company's policy as in effect from time to time.

          Payments to be made to the Executive pursuant to this paragraph 4(a)
          shall be made in a lump sum as soon as practicable after the
          Executive's Termination Date.  Except as may be otherwise expressly
          provided to the contrary in this Agreement, nothing in this Agreement
          shall be construed as requiring the Executive to be treated as
          employed by the Company following his Termination Date for purposes of
          any employee benefit plan or arrangement in which he may participate
          at such time.

     (b)  TERMINATION BY COMPANY FOR CAUSE.  If the Executive's Termination Date
          occurs during the Employment Period and is a result of the Company's
          termination of the Executive's employment on account of Cause (as
          defined below), then, except as agreed in writing between the
          Executive and the Company, the Executive shall have no right to future
          payments or benefits under this Agreement (and the Company shall have
          no obligation to make any such future payments or provide any such
          future benefits) for periods after the Executive's Termination Date.
          For purposes of this Agreement, the term "Cause" shall mean (1) the
          continuous failure by


                                       -3-
<PAGE>

          the Executive to substantially perform his duties under this
          Agreement, (2) the willful engaging by the Executive in conduct which
          is demonstrably and materially injurious to the Company or its
          affiliates, monetarily or otherwise, (3) conduct by the Executive that
          involves theft, fraud or dishonesty, or (4) the Executive's violation
          of the provisions of Section 6 hereof.

     (c)  TERMINATION FOR DEATH OR DISABILITY.  If the Executive's Termination
          Date occurs during the Employment Period on account of the Executive's
          death or disability (as defined below), then the Executive (or in the
          event of his death, his estate) shall be entitled to continuing
          payments of his Salary for the period commencing on his Termination
          Date and ending on the earliest of (i) the last day of the calendar
          month in which his Termination Date occurs, (ii) the last day of the
          Employment Period, or (iii) the date on which the Executive violates
          the provisions of Section 6 of this Agreement.   For purposes of this
          Agreement, the term "disability" shall mean the inability of the
          Executive to continue to perform his duties under this Agreement on a
          full-time basis as a result of mental or physical illness, sickness or
          injury for a period of 90 days within any 12-month period, as
          determined in the sole discretion of the CEO.

     (d)  TERMINATION BY THE COMPANY FOR REASONS OTHER THAN CAUSE.  If the
          Executive's Termination Date occurs during the Employment Period and
          is a result of the Executive's termination of employment by the
          Company for any reason other than Cause (and is not on account of the
          Executive's death, disability, or voluntary resignation, the mutual
          agreement of the parties or any other reason), then the Executive
          shall receive from the Company for the period commencing on his
          Termination Date and ending on the earliest of (i) last day of the
          Employment Period, (ii) the six month anniversary of his Termination
          Date, (iii) the date on which the Executive violates the provisions of
          Section 6 of this Agreement, or (iv) the date of the Executive's
          death, the Salary in effect as of his Termination Date, payable in
          accordance with the provisions of paragraph 3(a).  Notwithstanding the
          foregoing, the Company may, at any time, relieve the Executive of his
          duties for a specified period of time and such action on the part of
          the Company shall not be considered a termination of the Executive's
          employment hereunder.  During any period that the Executive has been
          relieved of his duties pursuant to the foregoing


                                       -4-
<PAGE>

          sentence, all provisions of this Agreement, other than the provisions
          of Section 2 which require the Executive to actively perform services
          for the Company, shall continue to remain in full force and effect.

     (e)  TERMINATION FOR VOLUNTARY RESIGNATION, MUTUAL AGREEMENT OR OTHER
          REASONS.  If the Executive's Termination Date occurs during the
          Employment Period on account of his voluntary resignation, mutual
          agreement of the parties, or any reason other than those specified in
          paragraphs (b), (c) or (d) above then, except as agreed in writing
          between the Executive and the Company, the Executive shall have no
          right to future payments or benefits under this Agreement (and the
          Company shall have no obligation to make any such future payments or
          provide any such future benefits) for periods after the Executive's
          Termination Date.

     (f)  NOTICE OF NON-RENEWAL.  If the Executive's Termination Date occurs at
          the end of the Employment Period on account of non-renewal of the
          Employment Period by either party in accordance with Section 1, then,
          except as agreed in writing between the Executive and the Company, the
          Executive shall have no right to future payments or benefits under
          this Agreement (and the Company shall have no obligation to make any
          such future payments or provide any such future benefits) for periods
          after the Executive's Termination Date.

Notwithstanding any other provision of this Agreement, the Executive shall
automatically cease to be an officer and/or director of the Company and its
affiliates as of his Termination Date.

     5.   SET-OFF.  The Company shall be entitled to set off against the amounts
payable to the Executive under this Agreement, any amounts owed to the Company
or its affiliates by the Executive.

     6.   CONFIDENTIAL INFORMATION.  The Executive agrees that:

     (a)  Except as may be required by the lawful order of a court or agency of
          competent jurisdiction, or except to the extent that the Executive has
          express authorization from the Company, he shall keep secret and
          confidential indefinitely all non-public information (including,
          without limitation, information regarding costs of new accounts,
          activity rates of different market niche customers and advertising
          results) concerning the Company and the subsidiaries which was
          acquired by or disclosed to the Executive during the course of his


                                       -5-
<PAGE>

          employment with the Company and not to disclose the same, either
          directly or indirectly, to any other person, firm, or business entity,
          or to use it in any way.

     (b)  Upon his Termination Date or at the Company's earlier request, he will
          promptly return to the Company any and all records, documents,
          physical property, information, computer disks or other materials
          relating to the business of the Company and its affiliates obtained by
          him during his course of employment with the Company.

     (c)  The Executive shall keep the Company informed of, and shall execute
          such assignments as may be necessary to transfer to the Company or its
          affiliates the benefits of, any inventions, discoveries, improvements,
          trade secrets, developments, processes, and procedures made by the
          Executive, in whole or in part, or conceived by the Executive either
          alone or with others, which result from any work which the Executive
          may do for or at the request of the Company, whether or not conceived
          by the Executive while on holiday, on vacation, or off the premises of
          the Company, including such of the foregoing items conceived during
          the course of employment which are developed or perfected after the
          Executive's termination of employment.  The Executive shall assist the
          Company or other nominated by it, to obtain patents, trademarks and
          service marks and the Executive agrees to execute all documents and to
          take all other actions which are necessary or appropriate to secure to
          the Company and its affiliates the benefits thereof.  Such patents,
          trademarks and service marks shall become the property of the Company
          and its affiliates.  The Executive shall deliver to the Company all
          sketches, drawings, models, figures, plans, outlines, descriptions or
          other information with respect thereto.

     (d)  To the extent that any court or agency seeks to have the Executive
          disclose confidential information, he shall promptly inform the
          Company, and he shall take such reasonable steps to prevent disclosure
          of Confidential Information until the Company has been informed of
          such requested disclosure, and the Company has an opportunity to
          respond to such court or agency.  To the extent that the Executive
          obtains information on behalf of the Company or any of the
          subsidiaries that may be subject to attorney-client privilege as to
          the Company's attorneys, the Executive shall take reasonable steps to
          maintain the confidentiality of such information and to preserve such
          privilege.


                                       -6-
<PAGE>

     (e)  Nothing in the foregoing provisions of this Section 6 shall be
          construed so as to prevent the Executive from using, in connection
          with his employment for himself or an employer other than the Company
          or any of its affiliates, knowledge which was acquired by him during
          the course of his employment with the Company and its affiliates, and
          which is generally known to persons of his experience in other
          companies in the same industry.

    7.  EQUITABLE REMEDIES.  The Executive acknowledges that the Company would
be irreparably injured by a violation of Section 6 and agrees that the Company,
in addition to other remedies available to it for such breach or threatened
breach, shall be entitled to a preliminary injunction, temporary restraining
order, other equivalent relief, restraining the Executive from any actual or
threatened breach of Section 6 without any bond or other security being
required.

     8.   DEFENSE OF CLAIMS.  The Executive agrees that, on and after the
Effective Date, he will cooperate with the Company and its affiliates in the
defense of any claims that may be made against the Company or its affiliates to
the extent that such claims may relate to services performed by him for the
Company. To the extent travel is required to comply with the requirements of
this Section 9, the Company, shall to the extent possible, provide the Executive
with notice at least 10 days prior to the date on which such travel would be
required and the Company agrees to reimburse the Executive for all of his
reasonable actual expenses associated with such travel; provided, however, that
if the Company reasonably expects the travel to be extensive or unduly
burdensome to the Executive from a financial perspective, the Executive may
provide to the Executive pre-paid tickets for transportation in connection with
such travel.

                                 EMPLOYMENT AGREEMENT


     This Agreement made and entered into as of the 3rd day of December, 1996
(the "Effective Date") by and between Ameritrade Holding Corporation (the
"Company"), and Robert T. Slezak (the "Executive"),

                                   WITNESSETH THAT:

     WHEREAS, the parties desire to enter into this Agreement pertaining to the
continued employment of the Executive by the Company;

     NOW THEREFORE, in consideration of the mutual covenants and agreements set
forth below, it is hereby covenanted and agreed by the Company and the Executive
as follows:

     1.   EMPLOYMENT PERIOD.  Subject to the terms of this Agreement, the
Company hereby agrees to employ the Executive as its Vice President, Treasurer
and Chief Financial Officer during the Employment Period (as defined below), and
the Executive hereby agrees to remain in the employ of the Company during the
Employment Period and to provide services during the Employment Period in
accordance with this Agreement.  The "Employment Period" shall be the period
beginning on the Effective Date and ending on the first anniversary thereof.
After the first anniversary of the Effective Date, the Employment Period shall
be automatically extended for three additional consecutive 12-month periods,
unless one party to this Agreement provides written notice of non-renewal to the
other at least 180 days before the last day of the then current Employment
Period.

     2.  DUTIES.  The Executive agrees that, during the Employment Period while
he is employed by the Company, he will devote his full time, energies and
talents to serving as the Vice President, Treasurer and Chief Financial Officer
of the Company, subject to the direction of the Chairman and Chief Executive
Officer of the Company (the "CEO").  The Executive shall have such duties and
responsibilities as may be assigned to him from time to time by the CEO,
including, but not limited to, providing decision-making support to the
subsidiaries of the Company, the CEO and the officers of the operating
subsidiaries and providing ongoing financial analysis and projections at the
corporate level.  The Executive shall perform all duties assigned to him
faithfully and efficiently, subject to the direction of the CEO and shall have
such authorities and powers as are inherent to the undertakings applicable to
his position and necessary to carry


<PAGE>

out the responsibilities and duties required of him hereunder; provided,
however, that the Executive shall not be required to perform any duties while he
is disabled (within the meaning of paragraph 4(c)).  Notwithstanding the
foregoing provisions of this Section 2, during the Employment Period, the
Executive may devote reasonable time to activities other than those required
under this Agreement, including the supervision of his personal investments, and
activities involving professional, charitable, educational, religious and
similar types of organizations, speaking engagements, membership on the boards
of directors of other organizations, and similar type activities, to the extent
that such other activities do not, in the judgement of the CEO, inhibit or
prohibit the performance of the Executive's duties under this Agreement, or
compete or conflict with the business of the Company or any of its subsidiaries.

     3.  COMPENSATION.  Subject to the terms and conditions of this Agreement,
during the Employment Period while the Executive is employed by the Company, the
Company shall compensate him for his services as follows:

    (a)  The Executive shall receive, for each 12-consecutive month period
         beginning on the Effective Date and each anniversary thereof, an
         annual salary of $250,000 (the "Salary"), which Salary shall be
         payable in substantially equal monthly or more frequent installments.
         The Executive's Salary rate shall be reviewed annually on or about
         January 1 of each year; provided, however, that in no event shall the
         Salary of the Executive be reduced to an amount that is less than the
         amount specified in this paragraph (a) (as the same may be increased
         from time to time) except to the extent that reductions of the same
         percentage are being made at the same time to the salaries of all
         other senior executive officers of the Company.

    (b)  The Executive shall be entitled to receive bonuses from the Company as
         determined in the sole discretion of the Board of Directors of the
         Company.

    (c)  Except as otherwise specifically provided to the contrary in this
         Agreement, the Executive shall be provided with the employee benefits
         and other fringe benefits and perquisites to the same extent and on
         the same terms and conditions as those benefits are provided by the
         Company from time to time to the Company's other senior executive
         officers.

    4.   RIGHTS AND PAYMENTS UPON TERMINATION.  The Executive's employment with
the Company may be terminated during the Employment Period by the Company or the
Executive at any time,

                                         -2-

<PAGE>

for any reason, without breach of this Agreement.  The Executive's right to
benefits and payments, if any, for periods after the date on which his
employment with the Company terminates for any reason (his "Termination Date")
shall be determined in accordance with the following provisions of this Section
4:

    (a)  MINIMUM PAYMENTS.  If the Executive's Termination Date occurs during
         the Employment Period for any reason, the employee shall be entitled
         to the following payments, in addition to any payments or benefits to
         which the Executive may be entitled under the following provisions of
         this Section 4 (other than this paragraph (a)) and the express terms
         of any employee benefit plan or arrangement in which the Executive
         participates as of his Termination Date:

         (i)       his earned but unpaid Salary for the period ending on his
                   Termination Date; and

         (ii)      his accrued but unpaid vacation pay for the period ending
                   with his Termination Date, as determined in accordance with
                   the Company's policy as in effect from time to time.

         Payments to be made to the Executive pursuant to this paragraph 4(a)
         shall be made in a lump sum as soon as practicable after the
         Executive's Termination Date.  Except as may be otherwise expressly
         provided to the contrary in this Agreement, nothing in this Agreement
         shall be construed as requiring the Executive to be treated as
         employed by the Company following his Termination Date for purposes of
         any employee benefit plan or arrangement in which he may participate
         at such time.

    (b)  TERMINATION BY COMPANY FOR CAUSE.  If the Executive's Termination Date
         occurs during the Employment Period and is a result of the Company's
         termination of the Executive's employment on account of Cause (as
         defined below), then, except as agreed in writing between the
         Executive and the Company, the Executive shall have no right to future
         payments or benefits under this Agreement (and the Company shall have
         no obligation to make any such future payments or provide any such
         future benefits) for periods after the Executive's Termination Date.
         For purposes of this Agreement, the term "Cause" shall mean (1) the
         continuous failure by the Executive to substantially perform his
         duties under this Agreement, (2) the willful engaging by the Executive
         in conduct which is demonstrably and


                                         -3-

<PAGE>

         materially injurious to the Company or its affiliates, monetarily or
         otherwise, (3) conduct by the Executive that involves theft, fraud or
         dishonesty, or (4) the Executive's violation of the provisions of
         Section 6 hereof.

    (c)  TERMINATION FOR DEATH OR DISABILITY.  If the Executive's Termination
         Date occurs during the Employment Period on account of the Executive's
         death or disability (as defined below), then the Executive (or in the
         event of his death, his estate) shall be entitled to continuing
         payments of his Salary for the period commencing on his Termination
         Date and ending on the earliest of (i) the last day of the calendar
         month in which his Termination Date occurs, (ii) the last day of the
         Employment Period, or (iii) the date on which the Executive violates
         the provisions of Section 6 of this Agreement.   For purposes of this
         Agreement, the term "disability" shall mean the inability of the
         Executive to continue to perform his duties under this Agreement on a
         full-time basis as a result of mental or physical illness, sickness or
         injury for a period of 90 days within any 12-month period, as
         determined in the sole discretion of the CEO.

    (d)  TERMINATION BY THE COMPANY FOR REASONS OTHER THAN CAUSE.  If the
         Executive's Termination Date occurs during the Employment Period and
         is a result of the Executive's termination of employment by the
         Company for any reason other than Cause (and is not on account of the
         Executive's death, disability, or voluntary resignation, the mutual
         agreement of the parties or any other reason), then the Executive
         shall receive from the Company for the period commencing on his
         Termination Date and ending on the earliest of (i) last day of the
         Employment Period, (ii) the six month anniversary of his Termination
         Date, (iii) the date on which the Executive violates the provisions of
         Section 6 of this Agreement, or (iv) the date of the Executive's
         death, the Salary in effect as of his Termination Date, payable in
         accordance with the provisions of paragraph 3(a).  Notwithstanding the
         foregoing, the Company may, at any time, relieve the Executive of his
         duties for a specified period of time and such action on the part of
         the Company shall not be considered a termination of the Executive's
         employment hereunder.  During any period that the Executive has been
         relieved of his duties pursuant to the foregoing sentence, all
         provisions of this Agreement, other than the provisions of Section 2
         which require the Executive


                                         -4-


<PAGE>

         to actively perform services for the Company, shall continue to remain
         in full force and effect.

    (e)  TERMINATION FOR VOLUNTARY RESIGNATION, MUTUAL AGREEMENT OR OTHER
         REASONS.  If the Executive's Termination Date occurs during the
         Employment Period on account of his voluntary resignation, mutual
         agreement of the parties, or any reason other than those specified in
         paragraphs (b), (c) or (d) above then, except as agreed in writing
         between the Executive and the Company, the Executive shall have no
         right to future payments or benefits under this Agreement (and the
         Company shall have no obligation to make any such future payments or
         provide any such future benefits) for periods after the Executive's
         Termination Date.

    (f)  NOTICE OF NON-RENEWAL.  If the Executive's Termination Date occurs at
         the end of the Employment Period on account of non-renewal of the
         Employment Period by either party in accordance with Section 1, then,
         except as agreed in writing between the Executive and the Company, the
         Executive shall have no right to future payments or benefits under
         this Agreement (and the Company shall have no obligation to make any
         such future payments or provide any such future benefits) for periods
         after the Executive's Termination Date.

Notwithstanding any other provision of this Agreement, the Executive shall
automatically cease to be an officer and/or director of the Company and its
affiliates as of his Termination Date.

    5.   SET-OFF.  The Company shall be entitled to set off against the amounts
payable to the Executive under this Agreement, any amounts owed to the Company
or its affiliates by the Executive.

    6.   CONFIDENTIAL INFORMATION.  The Executive agrees that:

    (a)  Except as may be required by the lawful order of a court or agency of
         competent jurisdiction, or except to the extent that the Executive has
         express authorization from the Company, he shall keep secret and
         confidential indefinitely all non-public information (including,
         without limitation, information regarding costs of new accounts,
         activity rates of different market niche customers and advertising
         results) concerning the Company and the subsidiaries which was
         acquired by or disclosed to the Executive during the course of his
         employment with the Company and not to disclose the same, either
         directly or indirectly, to any other


                                         -5-

<PAGE>

         person, firm, or business entity, or to use it in any way.

    (b)  Upon his Termination Date or at the Company's earlier request, he will
         promptly return to the Company any and all records, documents,
         physical property, information, computer disks or other materials
         relating to the business of the Company and its affiliates obtained by
         him during his course of employment with the Company.

    (c)  The Executive shall keep the Company informed of, and shall execute
         such assignments as may be necessary to transfer to the Company or its
         affiliates the benefits of, any inventions, discoveries, improvements,
         trade secrets, developments, processes, and procedures made by the
         Executive, in whole or in part, or conceived by the Executive either
         alone or with others, which result from any work which the Executive
         may do for or at the request of the Company, whether or not conceived
         by the Executive while on holiday, on vacation, or off the premises of
         the Company, including such of the foregoing items conceived during
         the course of employment which are developed or perfected after the
         Executive's termination of employment.  The Executive shall assist the
         Company or other nominated by it, to obtain patents, trademarks and
         service marks and the Executive agrees to execute all documents and to
         take all other actions which are necessary or appropriate to secure to
         the Company and its affiliates the benefits thereof.  Such patents,
         trademarks and service marks shall become the property of the Company
         and its affiliates.  The Executive shall deliver to the Company all
         sketches, drawings, models, figures, plans, outlines, descriptions or
         other information with respect thereto.

    (d)  To the extent that any court or agency seeks to have the Executive
         disclose confidential information, he shall promptly inform the
         Company, and he shall take such reasonable steps to prevent disclosure
         of Confidential Information until the Company has been informed of
         such requested disclosure, and the Company has an opportunity to
         respond to such court or agency.  To the extent that the Executive
         obtains information on behalf of the Company or any of the
         subsidiaries that may be subject to attorney-client privilege as to
         the Company's attorneys, the Executive shall take reasonable steps to
         maintain the confidentiality of such information and to preserve such
         privilege.


                                         -6-


<PAGE>

    (e)  Nothing in the foregoing provisions of this Section 6 shall be
         construed so as to prevent the Executive from using, in connection
         with his employment for himself or an employer other than the Company
         or any of its affiliates, knowledge which was acquired by him during
         the course of his employment with the Company and its affiliates, and
         which is generally known to persons of his experience in other
         companies in the same industry.

     7.  EQUITABLE REMEDIES.  The Executive acknowledges that the Company would
be irreparably injured by a violation of Section 6 and agrees that the Company,
in addition to other remedies available to it for such breach or threatened
breach, shall be entitled to a preliminary injunction, temporary restraining
order, other equivalent relief, restraining the Executive from any actual or
threatened breach of Section 6 without any bond or other security being
required.

    8.  DEFENSE OF CLAIMS.  The Executive agrees that, on and after the
Effective Date, he will cooperate with the Company and its affiliates in the
defense of any claims that may be made against the Company or its affiliates to
the extent that such claims may relate to services performed by him for the
Company. To the extent travel is required to comply with the requirements of
this Section 9, the Company, shall to the extent possible, provide the Executive
with notice at least 10 days prior to the date on which such travel would be
required and the Company agrees to reimburse the Executive for all of his
reasonable actual expenses associated with such travel; provided, however, that
if the Company reasonably expects the travel to be extensive or unduly
burdensome to the Executive from a financial perspective, the Executive may
provide to the Executive pre-paid tickets for transportation in connection with
such travel.

                                      ARTICLE IV

                       PARTICIPATION AND PARTICIPANT ELECTIONS


    4.1  PARTICIPATION.  Not later than October 31 of each Plan Year (except 
that for the first Plan Year such date shall be December 31) the Board shall 
designate in writing (i) each executive employee of the Company or any of its 
subsidiaries who shall be an Active Participant for such Plan Year and (ii) 
the performance guidelines to be used to determine the number of Credits 
which may be granted to such Active Participant for such Plan Year.  Promptly 
after making such designation, the Board shall furnish a written notice of

shall set forth for such executive employee the Grant Date, the performance 
guidelines to be used to determine the number of Credits which may be granted 
to such Participant for the particular Plan Year, and the Beginning Book

    4.2  PARTICIPANT ELECTIONS.  On or before November 15 of each Plan Year
(except that for the first Plan Year such date shall be January 15), an Active
Participant shall designate in an Election Agreement whether the Credits which
may be granted under Section 4.1 for a particular Plan Year shall be treated as
Cash Bonus Credits, 5-Year Credits, or Age-55 Credits; provided, that the


                                          3

<PAGE>

number of Credits designated by an Active Participant to be treated as Cash
Bonus Credits shall not exceed 50% of such Active Participant's actual Credits
for such Plan Year.  In the event an Active Participant does not timely enter
into an Election Agreement with the Company for any Plan Year, then such Active
Participant shall be deemed to have elected to treat all of such Active
Participant's Credits (if any) for such Plan Year as Age-55 Credits.  Except as
otherwise provided in the Plan, an Active Participant's election pursuant to an
Election Agreement shall be irrevocable upon the delivery of such Election
Agreement to the Committee.


                                      ARTICLE V

                                 PARTICIPANT ACCOUNTS

    5.1  ESTABLISHMENT OF ACCOUNT.  The Company shall establish in its records
a separate Account for each Participant.  Within each Account the Company shall
establish the following sub-accounts for each Participant:  a Cash Bonus Credit
Account, a 5-Year Credit Account, and an Age-55 Credit Account.  A Participant's
Account shall be used solely as a bookkeeping device for purposes of the Plan
and shall not constitute or be treated as a trust fund or reserve of any kind or
require the segregation of any assets of the Company.

    5.2  CREDITING OF ACCOUNTS.  On or before December 31 of each calendar year
but effective as of the last day of the preceding Plan Year, the Company will
credit to the Account of each Active Participant the Credits actually earned by
such Active Participant for the preceding Plan Year pursuant to the guidelines
referred to in Section 4.1; and such Credits shall be allocated among such
Active Participant's Cash Bonus Credit Account, 5-Year Credit Account, and
Age-55 Credit Account based upon the election made by such Active Participant
pursuant to Section 4.2 or as otherwise provided in Section 4.2.  For
bookkeeping purposes the Grant Date, number of Credits, and the Beginning Book
Value attributable to such Credits also shall be recorded in each Account.

    5.3  STATEMENT OF ACCOUNT.  The Company shall submit to each Participant,
within 120 days after the end of each calendar year, a statement in such form as
the Company deems appropriate setting forth a summary of such Participant's
Account as of December 31 of such calendar year (after all credits to such
account made on such December 31).

                                       VESTING

    6.1  VESTING OF CASH BONUS CREDITS.  A Participant's Cash Bonus Credits 
for a particular Plan Year shall vest in such Participant and become 
nonforfeitable by such Participant on the earlier of (i) the last day of such 
Plan Year, or (ii) the acceleration of such vesting by action of the Board.  
Notwithstanding the preceding sentence, a Participant's Cash Bonus Credits 
for a particular Plan Year shall not vest in such Participant pursuant to 
clause (i) in the event such Participant's employment with the Company or one 
of its subsidiaries has been terminated prior to the last day of such Plan 
Year for reasons other than such Participant's Disability or death.

    6.2  VESTING OF 5-YEAR CREDITS.  A Participant's 5-Year Credits for a
particular Plan Year shall vest in such Participant and become nonforfeitable by
such Participant on the earlier of (i) the last day of the fifth Plan Year
ending after such 5-Year Credits originally were credited to such Participant's
Account, (ii) the death of such Participant, (iii) the termination of such
Participant's employment by the Company or one of its subsidiaries solely by
reason of such Participant's Disability, or (iv) the acceleration of such
vesting by action of the Board.  For example, a Participant's 5-Year Credits for
the Plan Year beginning in 1991 will vest in such Participant under clause (i)
of the preceding sentence on the last day of the Plan Year ending in 1997;
however, such 5-Year Credits could vest in such Participant earlier than the
last day of the Plan Year ending in 1997 if clause (ii), (iii), or (iv) of the
preceding sentence actually is applicable.

    6.3  VESTING OF AGE-55 CREDITS.  A Participant's Age-55 Credits for a 
particular Plan Year shall vest in such Participant and become nonforfeitable 
by such Participant on the earlier of (i) the last day of the fifth Plan Year 
ending after such Age-55 Credits originally were credited to such 
Participant's Account, (ii) the death of such Participant, (iii) such 
Participant's reaching the age of fifty-five (55) years, (iv) the termination 
of such Participant's employment by the Company or one of its subsidiaries 
solely by reason of such Participant's Disability, or (v) the acceleration of 
such vesting by action of the Board.  For example, a Participant's Age-55 
Credits for the Plan Year beginning in 1991 will vest in such Participant 
under clause (i) of the preceding sentence on the last day of the Plan Year 
ending in 1997; however, such Age-55 Credits could vest in such Participant 
earlier than the last day of the Plan Year ending in 1997 if clause (ii), 
(iii), (iv), or (v) of the preceding sentence actually is applicable.

    6.4  FORFEITURE OF NON-VESTED CREDITS.  If a Participant's Credits for a 
particular Plan Year have not become fully vested and nonforfeitable pursuant 
to Sections 6.1, 6.2, or 6.3 at the time or as a result of the termination of 
such Participant's employment with the Company or one of its subsidiaries, 
then upon the termination of such Participant's employment by the Company or 
one of its subsidiaries the non-vested Credits shall be removed from such 
Participant's Account, and such Participant shall have no further rights with 
respect to the Credits so removed.

                                     ARTICLE VII

                                 PAYMENT OF BENEFITS

    7.1  CASH BONUS CREDITS.  The Company shall pay to a Participant the entire
value of his or her vested Cash Bonus Credits in one lump sum on or before the
first January 31 occurring after the end of the Plan Year in which such Cash
Bonus Credits vest in such Participant.  The value of such Participant's Cash
Bonus Credits shall be that amount determined by multiplying the number of such
vested Cash Bonus Credits by the difference determined by subtracting (i) the
applicable Beginning Book Value for such Cash Bonus Credits from (ii) the Book
Value for such Cash Bonus Credits as of the last day of the Plan Year in which
such Cash Bonus Credits vested in such Participant.  In the event the foregoing
computation results in a negative number, then the value of such vested Cash
Bonus Credits shall be zero.  (For example, consider a Participant whose 100
vested Cash Bonus Credits had a Beginning Book Value of $10 and a Book Value of
$12 as of the last day of the Plan Year in which such Cash Bonus Credits vested
in such Participant.  The value of this Participant's Cash Bonus Credits would
be $200 (100 X($12-$10)).

    7.2  5-YEAR CREDITS.  The Company shall pay to a Participant the entire
value of his or her vested 5-Year Credits in one lump sum on or before the first
January 31 occurring after the end of the Plan Year in which such 5-Year Credits
vest in such Participant. The value of such Participant's 5-Year Bonus 
Credits shall be that amount determined by multiplying the number of such
vested 5-Year Credits by the difference determined by subtracting (i) the
applicable Beginning Book Value for such 5-Year Credits from (ii) the Book Value
for such 5-Year Credits as of the last day of the Plan Year in which such 5-Year
Credits vested in such Participant.  In the event the foregoing computation
results in a negative number, then the value of such vested 5-Year Credits shall
be zero.

    7.3  TERMINATION OF EMPLOYMENT.  If a Participant's employment with the
Company or one of its subsidiaries terminates prior to such Participant's
reaching the age of fifty-five (55) years for any reason other than such
Participant's Disability or death, then


                                          6

<PAGE>

such terminated Participant shall be entitled to receive the entire value of his
or her vested Cash Bonus Credits, 5-Year Credits, and Age-55 Credits as of the
date of such termination; and such terminated Participant's non-vested Cash
Bonus Credits, 5-Year Credits, and Age-55 Credits shall be forfeited pursuant to
Section 6.4.  The value of such terminated Participant's vested Cash Bonus
Credits and 5-Year Credits shall be payable as provided in Section 7.1 or 7.2,
whichever is applicable.  The value of such terminated Participant's vested
Age-55 Credits shall be payable in one lump sum on or before the first January
31 after the first to occur of such Participant's reaching the age of 
fifty-five (55) years or such Participant's death; and such value shall be
determined by multiplying the number of such vested Age-55 Credits by the
difference determined by subtracting (i) the applicable Beginning Book Value for
such Age-55 Credits from (ii) the Book Value for such Age-55 Credits as of the
last day of the Plan Year immediately preceding the Plan Year in which such
Participant's employment by the Company terminated.  In the event the foregoing
computation results in a negative number, then the value of such vested Age-55
Credits shall be zero.

    7.4  AGE-55 CREDITS.  When a Participant reaches the age of fifty-five (55)
years, such Participant shall be entitled to receive the entire value of his or
her Cash Bonus Credits and Age-55 Credits (whether or not such Credits have
vested in such Participant) as of the December 31 immediately following the
Participant's 55th birthday, and (with respect to Credits subsequently earned)
on each December 31 thereafter (after all credits to such Participant's Account
which are to be made pursuant to the Plan on such December 31); and such value
shall be paid to the Participant in one lump sum on or before the first January
31 occurring after such December 31.  The value of such Cash Bonus Credits and
Age-55 Credits shall be that amount determined by multiplying the number of such
Credits by the difference determined by subtracting (i) the applicable Beginning
Book Value for such Credits from (ii) the Book Value for such Credits as of the
last day of the Plan Year ending prior to the Plan Year in which the Participant
reached age 55 or the last day of each Plan Year ending after the Participant
reached age 55, whichever is applicable.  In the event the foregoing computation
results in a negative number, then the value of such vested Credits shall be
zero.

    7.5  DEATH.  Upon the death of a Participant, such Participant's
Beneficiary or Beneficiaries shall be entitled to receive the entire value of
such deceased Participant's Cash Bonus Credits, 5-Year Credits, and Age-55
Credits (whether or not such Credits have vested in such Participant) as of the
December 31 immediately following the date of such Participant's death
(including any Credits credited to such Participant's Account on December 31 of
the calendar year in which such death occurs); and such benefits shall be paid
to the Participant's Beneficiary or Beneficiaries, as the case may be, in one
lump sum on or before the


                                          7

<PAGE>

first January 31 occurring after such December 31.  The value of such Cash Bonus
Credits, 5-Year Credits, and Age-55 Credits shall be that amount determined by
multiplying the number of such Credits by the difference determined by
subtracting (i) the applicable Beginning Book Value for such Credits from (ii)
the Book Value for such Credits as of the last day of the Plan Year ending prior
to the Plan Year in which such death occurs.  In the event the foregoing
computation results in a negative number, then the value of such vested Credits
shall be zero.

    7.6  DISABILITY.  If a Participant's employment with the Company terminates
solely because of such Participant's Disability, such Participant shall be
entitled to receive the entire value of his or her Cash Bonus Credits, 5-Year
Credits, and Age 55 Credits (whether or not such Credits have vested in such
Participant) as of the December 31 immediately following the Disability of such
Participant (after all Credits to such Participant's Account which are to be
made pursuant to the Plan on such December 31); and such value shall be paid to
the Participant in one lump sum on or before the first January 31 occurring
after such December 31.  The value of such Cash Bonus Credits, 5-Year Credits,
and Age-55 Credits shall be that amount determined by multiplying the number of
such Credits by the difference determined by subtracting (i) the applicable
Beginning Book Value for such Credits from (ii) the Book Value for such Credits
as of the last day of the Plan Year ending prior to the Plan Year in which such
Disability termination occurs.  In the event the foregoing computation results
in a negative number, then the value of such vested Credits shall be zero.

    7.7  ACCELERATED DISTRIBUTIONS.  The Board reserves the right in its
absolute discretion at any time to accelerate the time of vesting of any Credits
in a Participant and also to accelerate the payment to a Participant or a
Beneficiary or Beneficiaries (as the case may be) of some or all of the value of
the vested Credits in a Participant's Account.  No Participant who is a member
of the Board shall participate in any decision by the Board with respect to the
acceleration of vesting of Credits or of payments from such Participant's
Account.

    7.8  WITHHOLDING; PAYROLL TAXES.  To the extent required by applicable laws
in effect at the time payments are made under the Plan, the Company shall
withhold from payments made under the Plan any taxes required to be withheld
from such payments by federal, state or local laws.

                                     ARTICLE VIII

                               BENEFICIARY DESIGNATION

    8.1  BENEFICIARY DESIGNATION.  Each Participant shall have the right, at
any time, to designate in writing on a form prescribed by the Committee any
person or persons as the Beneficiary or Beneficiaries (both primary and
contingent) to whom payments under the Plan shall be made in the event of the
Participant's death prior to complete distribution of the benefits due the
Participant under the Plan.  Such form shall be filed with the Committee and
shall become effective when so filed.

    8.2  CHANGE OF BENEFICIARY.  Any Beneficiary designation may be changed by
a Participant by the filing of such change in writing on a form prescribed by
the Committee.  Effective upon its filing with the Committee prior to such
Participant's death, a new Beneficiary designation will cancel all Beneficiary
designations previously filed by a Participant.

    8.3  NO BENEFICIARY DESIGNATION.  If a Participant fails to designate a
Beneficiary pursuant to this Article VIII, or if all designated Beneficiaries
predecease the Participant, then the Participant's designated Beneficiary shall
be deemed to be the person or persons surviving the Participant in the first of
the following classes in which there is a survivor, in equal shares by
representation:

    (a)  The Participant's surviving spouse;

    (b)  The Participant's issue; or

    (c)  The personal representative of the Participant's estate.


                                      ARTICLE IX

                          AMENDMENT AND TERMINATION OF PLAN

    9.1  AMENDMENT.  The Board may amend the Plan at any time in whole or in
part or discontinue the Plan without terminating the Plan; however, no amendment
or discontinuance of the Plan shall decrease the amount of any Account then in
existence, without the written consent of the affected Participant.

    9.2  TERMINATION.  The Board may terminate the Plan at any time.  Upon any
such termination, the credits required to be made to a Participant's Account
shall be made as of the effective date of the Plan termination, all Credits
shall be fully vested in the respective Participants to whom such Credits have
been given, and all Participants in the Plan thereupon shall be paid the value
of


                                          9

<PAGE>

the Credits in their respective Accounts in a lump sum, such value to be
determined by multiplying the number of such Credits by the difference
determined by subtracting (i) the applicable Beginning Book Value for such
Credits from (ii) the Book Value for such Credits as of the last day of the Plan
Year ending prior to the effective date of such termination.  In the event the
foregoing computation results in a negative number, then the value of such
vested Credits shall be zero.


                                      ARTICLE X

                                    MISCELLANEOUS

    10.1  DILUTION.  In the event of any recapitalization, stock dividend,
stock split, combination of shares or other change in the shares of the Company,
then the Credits subject to the Plan shall be adjusted as and to the extent
appropriate, in the absolute discretion of the Committee, to provide each
Participant with the same relative rights before and after such change.

    10.2  CREDITOR STATUS.  Participants and their Beneficiaries shall have no
legal or equitable rights, interests, or claims in or to any particular property
or assets of the Company or any of its subsidiaries, nor shall they be
beneficiaries of, or have any rights, claims, or interests in or to, any life
insurance policies or annuity contracts (or the proceeds therefrom) now owned or
which hereafter may be acquired by the Company or any of its subsidiaries
("Policies").  Such Policies, proceeds, or other assets of the Company or any
of its subsidiaries shall not be held under any trust for the benefit of
Participants or their Beneficiaries or held in any way as collateral security
for the satisfaction or discharge of the obligations of the Company under the
Plan; however, such Policies, proceeds, and assets may be held in a trust if
such trust provides that such Policies, proceeds, and assets remain subject to
the claims of the general creditors of the Company or any of its subsidiaries in
the event of the bankruptcy or insolvency of the Company or any of its
subsidiaries.  Any and all of the assets of the Company or any of its
subsidiaries and such Policies (if any) shall be, and remain, the general and
unrestricted assets of the Company or any of its subsidiaries.  The obligation
of the Company or any of its subsidiaries under the Plan is and shall be merely
an unfunded and unsecured promise of the Company or any of its subsidiaries to
pay money in the future.

    10.3  NONASSIGNABILITY.  Neither a Participant nor a Beneficiary nor any
other person shall have any right to commute, sell, assign, transfer, pledge,
anticipate, mortgage, or otherwise encumber, transfer, hypothecate, or convey in
advance of actual receipt the amounts, if any, payable under the Plan, or any
part thereof, which are, and all rights to which are, expressly declared to be
nonassignable and nontransferable.  No part of any amounts


                                          10

<PAGE>

payable under the Plan shall, prior to actual payment, be subject to seizure or
sequestration for the payment of any debts, judgments, alimony, or separate
maintenance owed by a Participant or any other person nor be transferable by
operation of law in the event of a Participant's or any other person's
bankruptcy or insolvency.

    10.4  NOT A CONTRACT OF EMPLOYMENT.  The terms and conditions of the Plan
and of any Election Agreement entered into pursuant to the Plan shall not be
deemed to constitute a contract of employment between the Company or any of its
subsidiaries and a Participant, and a Participant (or a Participant's
Beneficiary) shall have no rights against the Company or any of its subsidiaries
under the Plan except as may be specifically provided in the Plan.  Moreover,
nothing in the Plan shall be deemed to give a Participant the right (i) to be
retained in the employ or other service of the Company or any of its
subsidiaries for any specific length of time, (ii) to interfere with the right
of the Company or any of its subsidiaries to discipline or discharge the
Participant at any time, (iii) to hold any particular position or responsibility
with the Company or any of its subsidiaries, (iv) to receive any particular
compensation from the Company or any of its subsidiaries, or (v) to be an Active
Participant for any particular Plan Year.

    10.5  NO EQUITY INTEREST.  Nothing in the Plan shall be deemed to give a
Participant (i) any capital stock or other equity interest in the Company or any
of its subsidiaries or (ii) the right to receive any shares of capital stock or
other equity interest in the Company or any of its subsidiaries.

    10.6  PARTICIPANT COOPERATION.  Each Participant shall cooperate with the
Company by furnishing any and all information requested by the Company to
facilitate the payment of benefits under the Plan, by taking such physical
examinations as the Company may deem necessary, and by taking such other actions
as reasonably may be requested by the Company.

    10.7  INCOMPETENT.  If the Committee reasonably determines that any
Participant or Beneficiary to whom a benefit is payable under the Plan is unable
to care for his or her affairs because of illness or accident, then any payment
due such Participant or Beneficiary (unless prior claim therefor shall have been
made by a duly authorized guardian or other legal representative) may be paid,
upon appropriate indemnification of the Company, to the person deemed by the
Committee to have current responsibility for the handling of the affairs of such
Participant or Beneficiary.  Any such payment shall be a payment for the account
of the Participant or Beneficiary and shall be a complete discharge of any
liability of the Company therefor.

                               TERMS AND CONDITIONS

1. Maker shall reimburse Bank for all expenses incurred in protecting or
   enforcing its rights. 
   Maker's liability under its Obligations ("all Maker's existing and future 
   obligations of whatever nature and whenever incurred to Bank") shall not be 
   affected by any of the following:
   -  Acceptance or retention by Bank of other property or interests as security
      for the Obligations, or for the liability of any person other than a 
      Maker with respect to the Obligations;
   -  Any release, extension, renewal, modification or compromise of any of 
      the Obligations or the liability of any obligor thereon; or
   -  Failure by Bank to resort to other security or any person liable for 
      the Obligations.
Each maker specifically consents to multiple renewals or extensions of the 
Obligations. This Note shall be deemed extended through the date of any 
advance made by Bank after the original maturity hereof; and any such advance 
shall constitute principal due under this Note.

2. REPRESENTATION, WARRANTIES AND COVENANTS. Each Maker represents, warrants 
   and covenants as follows:
   This Note, security agreement, deed of trust, mortgage, or other lien 
   document(s), if any, securing the Note have been duly authorized, executed 
   and delivered by the Maker and constitute legal, valid and binding 
   Obligations of Maker.
   This Note evidences a loan for business or agricultural purposes.
   Maker will provide business reports and with such frequency as Bank shall 
   request; and 
   Maker agrees to pay all costs of collection in connection with this Note, 
   including reasonable attorneys' fees and legal expenses.

3. DEFAULTS AND REMEDIES. Upon the occurrence of one or more of the following 
   events of default:
   - Maker fails to pay when due any of the Obligations, or to perform or 
     rectify breach of, any warranty or other undertaking by Maker in this Note 
     or the other Obligations; or breaches any other covenant or condition 
     described in any other document;
   - Any Maker, endorser, surety, or guarantor of any of the Obligations dies, 
     ceases to exist, makes an assignment for the benefit of creditors, becomes 
     insolvent or the subject of bankruptcy or insolvency proceedings;
   - Any representation made to induce Bank to extend credit under this Note or 
     otherwise is false in any material respect when made;
   - A material adverse change, in the opinion of Bank, occurs in the financial 
     or business condition of any Maker or of any endorser, surety or guarantor
     of this Note;
   - The entry of a judgment against any Maker;
   - Filing of any lien against any Maker;
   - The taking possession of any substantial part of the property of any Maker 
     at the instance of any governmental authority;
   - The dissolution, merger, consolidation, or reorganization of any Maker, or 
     other entity liable for this Obligation;
   - Any other event occurs which causes Bank in good faith to deem itself 
     insecure;

   then in such event, all of the Obligations shall, at the option of Bank and 
   without notice or demand, mature and become immediately due and payable; and 
   Bank shall have all rights and remedies for default provided by the Uniform 
   Commercial Code, and any other applicable law and/or the Obligations.

   All costs and expenses incurred by Bank in enforcing its rights under this 
   Note or any mortgage or other lien, endorsement, surety agreement, guarantee 
   relating thereto are the obligations of Maker and are immediately due and 
   payable. Interest shall accrue on such costs and expenses from the date of
   incurrence at the rate specified herein for delinquent Note payments. Each 
   Maker, endorser, surety and guarantor hereby waives presentment, protest, 
   demand, notice of dishonor, and the defense of any statute of limitations.

4. GENERAL. Without affecting the liability of any Maker, endorser, surety, or 
   guarantor, the holder may, without notice, renew or extend the time for 
   payment, accept partial payments, release or impair any collateral security 
   for the payment of this Note or agree to sue any party liable on it.

   Subject to rights afforded by law, Bank may, at any time and for any reason, 
   charge to or off-set against any amount then on deposit in any account 
   (including a savings certificate), whether or not then due, any and all debts
   or liabilities (sole, several, joint, or joint and severable, absolute or 
   contingent, due or not due, liquidated or unliquidated, secured or 
   unsecured) then owed to Bank by depositor or in the case of a multiple-party 
   account, by any party to such multiple-party account, and this agreement 
   shall be construed to be the consent of depositor and any such party for the 
   Bank to make such charge or off-set if consent be required by any person or 
   future law.

   Bank shall not be deemed to have waived any of its rights upon or under this 
   Note, or under any mortgage or other lien, endorsement, surety agreement, or 
   guarantee unless such waivers be in writing and signed by Bank. No delay or 
   omission on the part of Bank in exercising any right shall operate as a 
   waiver of such right or any other right. A waiver on any one occasion shall 
   not be construed as a bar to or waiver of any right on any future occasion. 
   All rights and remedies of Bank on liabilities or the collateral whether 
   evidenced hereby or by any other instrument or papers shall be cumulative and
   may be exercised singularly or concurrently.

   Maker, if more than one, shall be jointly and severally liable hereunder and
   all provisions hereof regarding the liabilities or security of Maker shall 
   apply to any liability or any security of any or all of them. This 
   agreement shall be binding upon the heirs, executors, administrators, 
   assigns or successors of Maker; shall constitute a continuing agreement, 
   applying to all future as well as existing transaction, whether or not of 
   the character contemplated at the date of this Note, and if all 
   transactions between Bank and Maker shall be at any time closed, shall be 
   equally applicable to any new transactions thereafter; shall benefit Bank, 
   its successors, and assigns; and shall so continue in force not 
   withstanding any change in any partnership party hereto, whether such 
   change occurs through death, retirement or otherwise.

   If any party of this Note is a married person, such person or persons 
   hereby separately charges his or her separate estate, including both that 
   now owned and that hereafter acquired, with the payment of this Note.

   This Note shall be construed according to the laws of the State of Nebraska.

   Unless the content otherwise requires, all terms used herein which are 
   defined in the Uniform Commercial Code shall have the meanings therein 
   stated.

   Any provision of this Note which is prohibited or unenforceable in any 
   jurisdiction shall, as to such jurisdiction, be ineffective to the extent 
   of such prohibition or unenforceability without invalidating the remaining 
   provisions hereof or affecting the validity or enforceability of such 
   provision in any other jurisdiction.
