ITEM 1. DESCRIPTION OF BUSINESS
 
INTRODUCTION
 
  The Ashton Technology Group, Inc. ("ATG(TM)", the "Company", "Ashton", or
the "Registrant") is engaged in the development and commercialization of
online transaction systems for participants in the U.S. and international
financial markets. The Company was founded in 1994 to take advantage of
commercial opportunities through the application of advanced telecommunication
and computing technologies to the area of electronic commerce. The Company is
currently organized as a parent company which has or will have four
subsidiaries: (1) Universal Trading Technologies Corporation ("UTTC(TM)"); (2)
Gomez Advisors, Inc. ("GA"); (3) Electronic Market Center, Inc. ("EMC"); and
(4) ATG(TM) International, Inc. ("ATG(TM) International") (not yet
incorporated). REB Securities, Inc. ("REB"), a broker-dealer whose
registration statement with the Securities and Exchange Commission (the "SEC"
or "Commission") is pending, is a wholly-owned subsidiary of UTTC(TM). All
subsidiaries are or will be wholly-owned, except for UTTC(TM), of which the
Company owns approximately 96% of the common stock. During the third quarter
of fiscal 1998, the Company sold its Computer Science Innovations, Inc.
("CSI(R)") subsidiary (see "Computer Science Innovations, Inc.").
 
  During the fiscal year ended March 31, 1997, all of the Company's revenues
were generated by CSI(R). During the most recent fiscal year ended March 31,
1998, approximately 91% of the Company's revenues were generated by CSI(R),
and the remaining 9% of revenues were generated by GA. Following the sale of
CSI(R), the Company continues to seek regulatory approval to operate its
VTS(TM) system (see "Universal Trading Technologies Corporation") and to seek
other means of generating revenue. At the present time, GA (see "Gomez
Advisors, Inc.") is the Company's sole source of revenue.
 
ATG(TM)
 
  ATG(TM)'s transaction systems incorporate or plan to incorporate the
Company's core areas of technological expertise which include:
 
  .  Internet and Extranet technologies and systems;
 
  .  Electronic authentication, encryption and trusted systems providing high
     grade data and information security;
<PAGE>
 
  .  Online transaction systems for use through traditional communication
     channels and through the Internet;
 
  .  Advanced computing technologies (including neural networks and other
     forms of artificial intelligence to provide analytical tools for
     prediction and decision support which are being implemented in future
     products).
 
  ATG(TM) focuses on the development and application of the Company's data and
information security technologies and initiatives for the future electronic
distribution of the Company's online transaction based products and services.
ATG(TM)'s data and information security products are being designed to provide
the elements of confidentiality, integrity, non-repudiation, access control
and auditability that are necessary to allow the use of both "open" and
proprietary networks in the conduct of Internet commerce.
 
  WORLDCOM INC./COMPUSERVE NETWORK SERVICES, INC. AGREEMENT
 
  In January 1998, the Company announced the signing of a global network
services agreement with CompuServe Network Services, Inc., ("CompuServe
Network") a division of WorldCom Inc. CompuServe Network offers a wide range
of integrated data communications including Internet, Intranet, and Extranet
connectivity to over 1,300 businesses in 115 countries. CompuServe Network's
high speed digital network backbone, which includes Virtual Private Networking
(VPN) and Virtual Private Line (VPL) integrated services, is expected to allow
ATG(TM)'s trusted online transaction systems to be accessed worldwide by
financial intermediaries serving institutional and individual investors.
CompuServe Network's network solutions are expected to provide wide access to
ATG(TM)'s customers and permit ATG(TM) to deploy and control its system's
state-of-the-art encryption, authentication, and firewall technologies.
 
  E.COM INTERNATIONAL STRATEGIC RELATIONSHIP
 
  In November 1997, the Company entered into a strategic relationship with
E.Com International, Inc. ("E.Com") to support its goal of providing remote
wireless access to its family of online transaction systems. Under this
relationship, the Company will be the exclusive distributor of E.Com's
products for the professional financial services market. E.Com develops and
markets integrated wireless mobile computing devices which provide user access
to the Internet, corporate networks, and remote databases. As the exclusive
distributor of E.Com products to the professional financial services market,
ATG(TM) will be able to offer its proprietary online transaction products and
the Company's Universal Trading System ("UTS(TM)"), an electronic pricing and
transaction facility for trading securities with access from remote locations.
The Company purchased 35,000 shares of E.Com common stock and warrants to
purchase E.Com common stock at $3.00 per share in a private placement.
 
UNIVERSAL TRADING TECHNOLOGIES CORPORATION
 
  UTTC(TM)'s business is to develop, market and operate electronic pricing and
transactional systems for the securities trading market. UTTC(TM)'s target
customers are broker-dealers, pension plan sponsors, institutional money
managers and mutual funds and other members of the professional investment
community. These professional investors may benefit from UTTC(TM)'s
proprietary technologies and pricing mechanisms which will enable them to
trade efficiently and cost effectively in an electronic trading environment
which features:
 
  .  Anonymity;
 
  .  State-of-the-art data and information security;
 
  .  Market neutrality;
 
  .  Exchange-standard surveillance;
 
  .  Advanced computer and telecommunications technologies;
 
                                       2
<PAGE>
 
  .  Accessibility from anywhere in the world through the Company's alliance
     with CompuServe Network and ultimately through the Internet;
 
  .  Total data security through the use of encryption, electronic
     authentication and firewalls;
 
  .  Seamless integration into major customers' trading and investment
     management platforms;
 
  .  Electronic connection to pre-trade analytics and post-trade industry
     wide clearing and settlement mechanisms; and
 
  .  The ability to upgrade and expand to take advantage of the rapid
     improvements in computer and communications hardware and software.
 
  UTTC(TM) has developed the UTS(TM)'s first product module, the volume
weighted average price ("VWAP(TM)") Trading System ("VTS(TM)"), an electronic
securities pricing and transaction system for trading exchange listed and
NASDAQ National Market securities. All trades through the VTS(TM) system will
be executed at the days VWAP(TM), the average price for a specific stock
weighted by the volume of shares of such stock traded "regular way" during the
day on all securities exchanges throughout the United States as reported to
the appropriate consolidated reporting authority.
 
  THE PHILADELPHIA STOCK EXCHANGE AGREEMENT
 
  On April 22, 1995, the Philadelphia Stock Exchange (the "Exchange" or
"PHLX") and UTTC(TM) agreed to integrate and deploy the VTS(TM) system as a
new trading product of PHLX. On September 18, 1995, UTTC(TM) and PHLX
memorialized the April 22 agreement in a formal contract for a term of five
years commencing from the date the VTS(TM) becomes operational on PHLX.
Operation of the system is contingent upon approval by the SEC of a rule
proposal filed by PHLX in April 1996. The contract provides, among other
things, for the deployment of the VTS(TM) as a new trading product of PHLX.
 
  PHLX RULE CHANGE
 
  On October 28, 1997, PHLX submitted an amendment to its original request for
a rule change, which was required because of the elapsed time since the
original submission, and also reflected enhancements made by UTTC(TM) to
VTS(TM). On December 31, 1997, the SEC republished the rule and amendments in
the Federal Register. The standard notification period for the SEC to respond
is 35 to 90 days--though the SEC may extend this period with the Exchange's
consent. It is management's belief that approval of VTS(TM) as a facility of
the Exchange relates, in part, to operational issues related to the Exchange
and not to UTTC(TM) or the VTS(TM). Since the first filing in April 1996, and
the special investigation of PHLX by the SEC culminating in March 1997, PHLX
adopted significant governance changes, ceased full clearing agency services
and, after receiving merger or acquisition proposals from the Chicago Board
Options Exchange and the American Stock Exchange ("AMEX"), has agreed to enter
into an agreement to be acquired by AMEX.
 
  The Company has developed a working system in accordance with its contract
with PHLX, and continues to support the Exchange in efforts to secure
regulatory approval of VTS(TM) as a facility of the Exchange. The business and
regulatory environment for introducing new trading systems has become more
flexible based on proposals announced by the SEC in April 1998 regarding
alternate trading systems ("ATSs"). On April 16, 1998, the SEC proposed new
rules and rule amendments that, if adopted, will permit ATSs to choose whether
to register as national securities exchanges, or to register as broker-dealers
which must comply with additional requirements depending on their activities
and trading volume. Additionally, the SEC proposed to exclude from rule filing
requirements certain pilot trading systems to be launched by national
securities exchanges and self-regulatory organizations (collectively "SROs").
The latter regulation, if and when adopted, may allow the Company to introduce
its products, regardless of whether PHLX rule proposal is approved by the SEC.
Anticipating adoption of these new regulations, the Company currently is
exploring the best structure for launching its existing electronic trading
product and products under development, e.g. through an existing SRO facility,
as a broker-dealer, or as a new and independent registered exchange.

GOMEZ ADVISORS, INC.
 
  Gomez Advisors, Inc. ("GA") was formed in May 1997 as a wholly owned
subsidiary by the Company together with Julio Gomez and John Robb, formerly of
Forrester Research, Inc. and Dr. Alex Stein from FarSight Financial. GA
provides independent advice with respect to online investing and provides
clients in the financial services industry with consulting advice concerning
the use of the Internet as a tool for establishing electronic client
relationships, marketing, and the interactive distribution of securities. The
range of Internet brokerage consulting services provided through GA includes
strategy development, product and interface design, and implementation
planning. GA also publishes proprietary evaluations of Internet financial
services through its Internet Broker Scorecard and Internet Banker Scorecard
rankings. GA commenced generating revenue in October 1997 and has continued to
increase its business base since that time.
 
ELECTRONIC MARKET CENTER, INC.
 
  On June 4, 1998, the Company formed Electronic Market Center, Inc. as a
wholly owned subsidiary. This subsidiary is expected to operate and market the
Company's to be developed distributed open finance system called the
electronic market center ("eMC(TM)"). The Company intends to design eMC(TM)
for interactive market access by member users and to provide a global
electronic distribution channel for all types of financial products and
services. Although the Company has designed the specifications for the
eMC(TM), there can be no assurance that the Company will be able to finance
the development or to actually develop such finance system.
 
REB SECURITIES, INC.
 
  REB is a wholly owned broker-dealer subsidiary of UTTC(TM). REB expects
that, upon approval of its application for registration with the Commission,
National Association of Securities Dealers, Inc., and state authorities, it
will provide institutional "soft dollar" services pursuant to Section 28(e) of
the Exchange Act and brokerage services to banks, broker-dealers, insurance
companies, and other financial intermediaries.
 
ATG(TM) INTERNATIONAL, INC.
 
  The Company currently is in the process of forming ATG(TM) International,
Inc. as a wholly owned subsidiary. The international markets represent
potential significant growth opportunities for the application of ATG(TM)'s
technology and skills to the development of proprietary online transaction
systems for global financial markets. In November 1997, the Company entered
into a strategic initiative with Tianjin New Hong Chen Technology & Trading
Company to introduce its online trading technology and systems to the
financial markets in China.
 
COMPUTER SCIENCE INNOVATIONS, INC.
 
  CSI(R) was a subsidiary of the Company. CSI(R) was incorporated in Florida
in March 1983 and specialized in utilizing computer technologies and
sophisticated mathematical techniques to address complex information retrieval
and management problems. During the past year, CSI(R) was the primary revenue
provider for the Company.
 
  On November 6, 1997, ATG(TM) sold CSI(R) to George H. Milligan and Susanne
L. Cavadeas, as Trustees of the Trust Created by The Computer Science
Innovations, Inc. Leveraged ESOP, for $1,723,000, payable as follows: (1)
repayment of a $500,000 loan plus interest of $28,875, (2) $600,000 in cash,
and (3) a five year 8 1/4% Note of $594,125. The Company recognized an
accounting loss on the sale of $385,930; however, on a cash basis, the Company
realized a gain on the sale of $101,992. In addition, the Company received
cash in the amount of approximately $340,000 due to a Tax Allocation Agreement
(see "Tax Allocation Agreement").

INITIAL PUBLIC OFFERING
 
  On May 2, 1996, ATG(TM) completed an initial public offering (the
"Offering") of 2,472,500 shares of common stock, par value $0.01 per share
(the "Common Stock") at an initial public offering price of $4.50 per share
and 2,472,500 redeemable common stock purchase warrants at $.25 per warrant.
The Common Stock and the warrants are separately tradable. As a result of the

  In April 1997, UTTC(TM) completed a private placement of $3,000,000 notes,
consisting of $2,550,000 nonconvertible and $450,000 convertible notes, to
accredited investors. The convertible notes are convertible into 450,000
shares of UTTC(TM) common stock. These notes bear interest at 9% per annum,
payable annually in arrears on January 31, 1998 and are due on January 31,
1999 or after the earlier conversion or prepayment of the Notes. The Company
received net proceeds of approximately $2,596,655 after deducting debt
issuance costs of $403,345. A total of $2,975,000 of notes were exchanged into
Series B Convertible Preferred Stock (see "ATG(TM) Series A and Series B
Private Placement and Exchange Offer").
 
ATG(TM) SERIES A AND SERIES B PRIVATE PLACEMENT AND EXCHANGE OFFER
 
  On September 18, 1997, the Company commenced a private offering and exchange
offer pursuant to which it offered to certain investors (i) up to 250,000
shares of its Series A Convertible PIK Preferred Stock (with a liquidation
preference of $10.00 per share) ( the "Series A Preferred"); (ii) up to
250,000 shares of its Series B Convertible Preferred Stock (with a liquidation
preference of $10.00 per share) (the "Series B Preferred"); and (iii) the

Series B Preferred for up to $3,000,000 of convertible and non-convertible
notes issued by UTTC(TM) (the "UTTC(TM) Notes"). The Series A Preferred pays
cumulative dividends semi-annually at an annual rate of $0.50 per share and is
payable in additional shares of Series A Preferred until February 15, 2000. At
any time after February 15, 1998, each holder of shares of Series A Preferred
will have the right to convert each share of Series A Preferred into: (i) ten
shares of Common Stock; and (ii) one two-year warrant to purchase three shares
of the common stock, par value $0.01 per share, of UTTC(TM) (the "UTTC(TM)
Common Stock"), with an exercise price of $0.75 per share, subject to
adjustment. The Series B Preferred pays cumulative dividends semi-annually at
an annual rate of $0.90 per share. At any time after June 30, 1998, each
holder of shares of Series B Preferred has the right to convert each share of
Series B Preferred into: (i) six shares of Common Stock; and (ii) one two-year
warrant to purchase two shares of UTTC(TM) Common Stock, with an exercise
price of $0.75 per share, subject to adjustment.
 
  The Company sold all 250,000 shares of its Series A Preferred at $10.00 and
realized gross proceeds of $2,500,000. The Series A Preferred offering closed
on January 15, 1998. The Company closed the Exchange Offer transaction after
receiving the tender of $2,975,000 of the UTTC(TM) Notes for which the Company
issued 297,500 shares of Series B Preferred Stock. The Company extended its
private offering to institutional and accredited investors of Series B
Preferred until May 15, 1998. As of March 31, 1998, the Company had received
signed Subscription Agreements for 587,500 shares of the Series B Preferred
offered. The Series B transaction closed on May 6, 1998 after being
oversubscribed by 40,000 shares of Series B Preferred. The Company realized
gross proceeds of $2,900,000. The Company incurred transaction costs in
connection with the issuance of the Series A Preferred and the Series B
Preferred, as well as the issuance of the Series C Preferred (as defined
below) described below, in the aggregate amount of approximately $1.6 million.
 
 
ATG(TM) SERIES C CONVERTIBLE PREFERRED STOCK
 
  On January 27, 1998, the Company completed the sale of 100,000 shares of the
Series C Convertible Preferred Stock to a group of foreign investors (the
"Series C Investors"), with a liquidation preference of
 
                                       5
<PAGE>
 
$10.00 per share (the "Series C Preferred"), for an aggregate purchase price
of $1,000,000. Holders of the Series C Preferred will have the right to
convert each share of Series C Preferred into one share of Common Stock at the
conversion price which shall be equal to the following: (i) if the Market
Price (as hereinafter defined) on the Conversion Date (as hereinafter defined)
is less than $1.8774, the conversion price is equal to the lesser of 75% of
the Market Price at the Conversion Date or $1.2516; and (ii) if the Market
Price at the Conversion Date is equal to or greater than $1.8774, the
conversion price is equal to $1.2516 plus 50% of the difference between the
Market Price at the Conversion Date and $1.8774. The "Market Price" means the
average of the closing bid price per share of the Common Stock over the five
consecutive trading days ending on the trading day immediately preceding the
date the holder elects to convert the Series C Preferred (the "Conversion
Date"). In addition, the Series C Investors will receive warrants exercisable
into an aggregate of 100,000 shares of Common Stock at an exercise price of
105% of the Market Price for a period of 5 years.
 
  As of March 31, 1998, 50,000 shares of the Series C Preferred were converted
into 281,071 shares of Common Stock. Between March 31 and April 21, 1998, the
remainder of the shares of Series C Preferred were converted into
314,342 shares of Common Stock. The fees paid for the Series C Shares were as
follows: 5,000 Series C Shares, $50,000, and a warrant to purchase 100,000
shares of Common Stock at 105% of the Market Price to Settondown Capital
International Ltd. (the "Placement Agent"). In addition, the Company paid
$50,000 and is expected to grant an option to purchase 150,000 shares of
Common Stock at $1.875 per share to Adirondack Capital, L.L.C., whose managing
director is a director of the Company, for services in structuring the
offering.
 
ATG(TM) SERIES D AND E CONVERTIBLE PREFERRED STOCK
 
  On April 3, 1998 (the "Subscription Date"), the Company entered into a
Private Equity Line of Credit Agreement (the "Private Equity Agreement") with
a group of accredited investors (the "Private Equity Investors") which
provides for an aggregate commitment of $18,000,000 to the Company. On the
Subscription Date the Private Equity Investors purchased three shares of
Series D Convertible Preferred Stock (the "Series D Preferred") with a
liquidation preference of $1,000,000 per share for an aggregate purchase price
of $3,000,000 and the Company agreed to promptly file a registration statement
with the Securities and Exchange Commission under the Securities Act,
registering shares of Common Stock issuable in connection with the
transactions contemplated by the Private Equity Agreement (the "Registration
Statement"). The Company filed this registration statement with the Commission
on June 29, 1998. The Agreement provides that within five days after the
Registration Statement has been filed, and subject to the satisfaction of
certain other conditions, the Private Equity Investors will purchase two
shares of Series E Convertible Preferred Stock (the "Series E Preferred") with
a liquidation preference of $1,000,000 per share for an aggregate purchase
price of $2,000,000. Following the purchase of the Series E Preferred and
subject to the satisfaction of certain other conditions, the Company may from
time to time put (each, a "Put") to the Private Equity Investors shares of the
Common Stock for an aggregate Put price of $13,000,000. The Put price per
share is an amount equal to 85% of the average of the lowest bid prices of
such Common Stock over the seven day period beginning three days before and
ending three days after the Company gives notice of a Put. On the completion
of each Put, the Company has agreed to pay the Placement Agent an amount equal
to 5% in cash of the amount of each Put and has agreed to pay a fee of 5% cash
to Adirondack Capital, L.L.C., whose managing director is a director of the
Company.
 
  Under the terms of the Private Equity Agreement, the Company has agreed to
hold $1,000,000 of the proceeds received on the Subscription Date in cash or
government securities until the Company (i) receives shareholder approval for
the issuance of 20% or more of its Common Stock in connection with the
transactions contemplated by the Agreement (the "Required Approval") or (ii)
is able to increase its issued and outstanding Common Stock by at least
4,000,000 shares through the conversion of Convertible Preferred Stock (other
than Common Stock to be issued in connection with the Private Equity
Agreement). If neither of these events has occurred within 90 days after the
Subscription Date, the Company must return the $1,000,000 plus a 10% premium,
to the Private Equity Investors. On May 29, 1998, the Company held a Special
Meeting of its stockholders at which time the stockholders approved the
increase in the Company's Common Stock to 60,000,000 shares and its Preferred
Stock to 3,000,000 shares, thus removing the stipulation on holding the
$1,000,000 cited above.

  The Private Equity Investors are not obligated to purchase the Series E
Preferred or any Put shares unless, among other things, (i) the Company has
received the Required Approval, (ii) the Registration Statement is filed (the
Registration Statement must be effective in order for the Private Equity
Investors to be obligated to purchase the Put shares), (iii) the Company is
listed and its Common Stock is trading on a national exchange or quotation
system, (iv) the closing bid price of the Common stock on the day immediately
preceding such purchase is at least $1.50 per share, and (v) the Common Stock
has traded at an average volume of at least 25,000 shares a day for the thirty
trading days preceding such purchase.
 
  The Series D Preferred may not be converted into Common Stock until the
earlier of (i) 60 days following the Subscription Date or (ii) the date the
Registration Statement has been filed. The conversion price of the Series D
Preferred is an amount equal to 75% of the average closing bid price per share
over the five days preceding the conversion date (the "Market Price"). The
conversion price of the Series E Preferred is 80% of the Market Price. Each of
the Series D Preferred and Series E Preferred (i) ranks pari passu with the
other authorized Preferred Stock of the Company and (ii) is entitled to a
cumulative dividend of 8% per annum on its respective liquidation preference.
 
  On the Subscription Date, the Private Equity Investors received warrants
(each, a "Warrant") to purchase up to an aggregate of 250,000 shares of Common
Stock and will receive additional Warrants to purchase up to an aggregate of
100,000 of such shares on the completion of the purchase of the Series E
Preferred. The Warrants are exercisable for five years at an exercise price of
120% of the average closing bid price of the Common stock over the five
trading days preceding the Subscription Date.
 
  On the Subscription Date, the Company paid the Placement Agent, a fee of (i)
$150,000, (ii) 0.15 shares of Series D Preferred, (iii) a Warrant, on the same
terms as the Warrants issued to the Private Equity Investors, to purchase up
to 190,000 shares of Common Stock, (iv) 20,000 shares of Common Stock and (v)
attorney fees of $30,000. In addition, the Company paid a fee of $150,000 and
is expected to grant an option to purchase 450,000 shares of Common Stock at
$1.875 per share to Adirondack Capital, L.L.C., whose managing director is a
director of the Company, for its assistance in structuring the transaction.
Upon the completion of the purchase of the Series E Shares, the Company has
agreed to pay the Placement Agent (i) an amount equal to 5% of the proceeds of
such purchase, (ii) 0.1 shares of Series E Preferred, and (iii) a Warrant to
purchase up to 60,000 shares of the Common Stock. In addition, the Company
paid an amount equal to 5% of the proceeds of such purchase to Adirondack
Capital, L.L.C., the managing director of which is a director of the Company.
On the completion of each Put by the Company pursuant to the Series E
Agreement, the Company has agreed to pay the Placement Agent an amount equal
to 5% of the proceeds of each such Put.
 
OWNERSHIP OF SUBSIDIARIES
 
  ATG(TM) owns (i) approximately 96% of the outstanding common stock of
UTTC(TM) and (ii) 100% of the outstanding common stock of GA. During this
fiscal year, the Company increased its ownership of UTTC(TM) from 80% to 96%
by receiving: (i) approximately 6,000,000 shares of UTTC(TM) common stock in
connection with the Exchange Offer; (ii) approximately 4,800,000 shares of
UTTC(TM) common stock for the payment of certain guaranteed obligations; (iii)
3,000,000 shares of UTTC(TM) common stock for existing development advances;
and (iv) 5,000,000 shares of UTTC(TM) common stock for $2.5 million of the
proceeds from the Series B Offering.
 
COMPETITION
 
  The Company and its subsidiaries operate in several competitive markets.
ATG(TM)'s competition in the commercial markets principally comes from larger,
better-established companies, many of which have financial, sales and
marketing resources substantially greater than ATG(TM). In online trading
systems, the UTS(TM) system will compete with other electronic trading
systems, including Reuters, N.A.'s Instinet system, Investment Technology
Group, Inc.'s POSIT system and Optimark Technologies, Inc.'s proposed Optimark
system. The Company believes that competitive criteria includes quality of
trade execution, pricing and reliability of post-execution processing and
settlement operations. The UTS(TM) system will also compete with various
national and
 
                                       7
<PAGE>
 
regional securities exchanges for trade execution services. The automated
trade execution and analytical services to be offered by the UTS(TM) system
will compete with services offered by leading brokerage firms and other
information service and transaction processing firms. In the advisory/product
research area, Forrester Research, Inc., Gartner Group and J. D. Power &
Associates are competitors. In distribution networks, the Company's
competition would be national and regional securities exchanges and financial
intermediary private networks such as Merrill Lynch and Bloomberg L.P.
 
  UTTC(TM)'s success is heavily dependent upon the acceptance of the UTS(TM)
by institutional investors. Failure to obtain such acceptance could result in
lower share volumes and a lack of liquidity on the UTS(TM). Market and
customer acceptance of the UTS(TM) will depend upon, among other things,
UTS(TM)'s operational performance, which has not yet been tested in the
environment of actual equity market trading activity. In addition, once
operational, the UTS(TM)'s institutional customers may discontinue the use of
the UTS(TM) at any time. While the Company's management continues to solicit
customers to use the UTS(TM), any commitments are dependent upon the UTS(TM)
becoming operational at PHLX or, in the alternative, at an independent broker-
dealer or exchange. There can be no assurance that UTTC(TM) will attract a
sufficient number of customers to the UTS(TM). Failure to introduce
successfully and market the UTS(TM) could result in a material adverse effect
on UTTC(TM) and the consolidated operations of the Company.
 
DEVELOPMENT COSTS
 
  As a development stage company which has had a limited operating history,
the company is subject to the risks and difficulties common to new businesses.
During the fiscal year ended March 31, 1998, the Company incurred $196,974 of
development costs compared with $3,382,848 of development costs on a
consolidated basis for the fiscal year ended March 31, 1997. During the
previous fiscal year, ATG(TM) incurred development costs of $2,049,651 for the
design and development of the Ashton Technology Encryption Device ("ATED") and
the encryption client-server. Separately, UTTC(TM) incurred costs of
$1,333,197 for the development of the UTS(TM) system which will be an
electronic pricing and transaction facility for trading securities.
 
PROPRIETARY RIGHTS
 
  ATG(TM)'s success depends to some degree on the protection of its
proprietary rights. ATG(TM) and its subsidiaries regard their respective
products as proprietary and rely primarily on a combination of trademark and
trade secret protection, employee and third party confidentiality and non-
disclosure agreements, license agreements and other intellectual property
protection methods to protect their proprietary rights. Neither ATG(TM),
UTTC(TM) nor GA currently holds any material patents or has filed for
copyright protection. UTTC(TM) has filed "intent-to-use" or "actual use"
documents to the Patent & Trademark Office for all of the products presently
available or currently being developed. UTTC(TM)'s products are generally
licensed to customers on a "right to use" basis pursuant to a non-transferable
license that generally restricts the customer's use to internal purposes.
 
GOVERNMENT REGULATION
 
  The UTS(TM) will be subject to significant government regulation by the
Commission and SROs which are charged with protecting the interests of the
investing public and the integrity of the securities markets. Originally, the
VTS(TM) system had been developed as a facility of PHLX, an SRO, and is
subject to regulatory approval by the SEC. Section 19(b) of the Exchange Act
and Rule 19b-4 promulgated thereunder require PHLX to file any proposed rules
changes with the SEC. The concept of the UTS(TM) system, which would
constitute a new PHLX facility accompanied by new PHLX rules, must be filed as
a proposed rule change (the "Rule Change proposal"). In this regard, PHLX
management was authorized by its Board of Governors to submit a proposed rule
change filing relating to the UTS(TM) system with the SEC, which published a
notice of the terms of the substance of the proposed rule change on September
4, 1996 and gave interested persons an opportunity to submit written data,
views, and arguments concerning such proposed rule change. In order to approve
the proposed Rule Change, the Commission must determine that the UTS(TM)
filing is consistent with the purposes of the Exchange Act, particularly
Section 6 of the Exchange Act, which provides standards governing the rules of
 
                                       8
<PAGE>
 
national securities exchanges. In October 1997, PHLX submitted a second
amendment of the proposed Rule Change to the SEC. In December 1997, the SEC
published a notice in the Federal Register soliciting comments on the proposed
rule change. There can be no assurance that the Commission will not require
further amendment to the PHLX Rule Change proposal or that the Commission will
approve the Rule Change proposal in the amended form. The Company is unable to
predict whether or when such approval of PHLX request will be received.
 
YEAR 2000/DOW 10,000 COMPLIANCE
 
  The Company has assessed the potential impact of what is commonly referred
to as the "Year 2000" issue, concerning the inability of certain information
systems and automated equipment to properly recognize and process dates
containing the Year 2000 and beyond. If not corrected, these systems and
equipment could fail or create erroneous results. The Company currently is in
the process of determining if any of its systems and equipment present Year
2000 issues. Regardless of the Year 2000 compliance of the Company's systems,
there can be no assurance that the Company will not be adversely affected by
the failure of others to become Year 2000 compliant. The potential liabilities
and costs associated with the Year 2000 compliance cannot be estimated with
certainty at this time. Because of these uncertainties regarding others, there
can be no assurance that the Year 2000 issue will not have a material
financial impact in any future period.
 
  Additionally, the Company has assessed the potential impact of the Dow Jones
Industrial Average (the "Dow" or "DJIA") exceeding 10,000 ("Dow 10,000"). The
potential issue involves whether certain information systems and automated
equipment may be unable to process and recognize a Dow in excess of 9,999. If
not corrected, these systems and equipment could fail or create erroneous
results. The Company currently is in the process of determining if any of its
systems and equipment present Dow 10,000 compliance issues. Regardless of the
Dow 10,000 compliance of the Company's systems, there can be no assurance that
the Company will not be adversely affected by the failure of others to become
Dow 10,000 compliant. The potential liabilities and costs associated with the
Dow 10,000 compliance cannot be estimated with certainty at this time. Because
of these uncertainties regarding others, there can be no assurance that the
Dow 10,000 issue will not have a material financial impact in any future
period.
 
EMPLOYEES
 
  As of March 31, 1998, the Company and its subsidiaries employed a total of
25 people.

ITEM 3. LEGAL PROCEEDINGS
 
  Alliant Techsystems, Inc. ("Alliant") with whom the Company has a contract
for the production of certain ATED encryption devices, has demanded payment of
approximately $292,000 under that contract, which the Company is contesting.
On October 22, 1997, ATG(TM) filed a complaint against Alliant in the court of
Common Pleas, County of Philadelphia, Pennsylvania for damages for failure of
Alliant to perform its obligations under its contract with ATG(TM). On
December 15, 1997, Alliant filed its answer and counterclaims seeking damages
in an amount "in excess of $50,000."

  On May 1, 1997, David N. Rosensaft ("Rosensaft") commenced an action in the
United States District Court for the Southern District of New York entitled
"David N. Rosensaft vs. The Ashton Technology Group, Inc., Universal Trading
Technologies Corporation, The Dover Group, Inc. and Fredric W. Rittereiser
(collectively, the "Defendants")" No. 97 Civ. 3138 ("Rosensaft Action"),
asserting ten claims against the defendants including breach of contract and
securities fraud and seeking, inter alia, specific performance of the
Settlement Agreement, dated January 30, 1997, between and among the parties or
in the alternative, actual and consequential damages in an amount to be proved
at trial in addition to punitive damages.
 
  On April 9, 1998, the parties agreed to a settlement of all claims in
consideration of $1,133,020 paid to Rosensaft by the defendants (ATG(TM),
UTTC(TM) and the Dover Group, Inc.) and a Stipulation and Order of Dismissal
was filed with the Court on April 10, 1998. ATG(TM)'s portion of the
settlement is $760,000.
 
  On May 29, 1998, Rosensaft ("Rosensaft") served the Company with a complaint
in the United States District Court for the Southern District of New York
entitled "David Rosensaft vs. Universal Trading Technologies Corporation and
The Ashton Technology Group, Inc." No. 98 Civ. 3681, asserting five claims
against the Company and its subsidiary, UTTC(TM) for breach of the Company's
fiduciary duty to Rosensaft as a minority shareholder of UTTC(TM) (Third Cause
of Action), for invalid amendments to the certificates of incorporation of
UTTC(TM) and the Company and invalid issuance of UTTC(TM) stock to the Company
(Fourth Cause of Action) and for improper issuance of additional shares of
UTTC(TM) common stock to the Company (Fifth Cause of Action).
 
  More specifically, the First Cause of Action alleges that in 1995 the
Company breached its March 7, 1995 agreement with Rosensaft by issuing only
2,000,000 shares of UTTC(TM) common stock to him in violation of a provision
of that agreement that allegedly entitled him to receive 2,450,000 shares of
UTTC(TM) common stock.
 
  The Second, Third, Fourth and Fifth Causes of Action allege that, in causing
UTTC(TM) to issue approximately 19 million shares of UTTC(TM) common stock to
ATG(TM) in September 1997, allegedly without adequate consideration, the
Company improperly diluted Rosensaft's share of UTTC(TM) common stock from
6.7% to 1.38% in violation of Delaware corporate law and in breach of
Rosensaft's March 7, 1995 agreement with the Company.
 
  The relief sought by Rosensaft is as follows: in the First Cause of Action,
450,000 shares of UTTC(TM) common stock, or damages to be determined at trial,
but not less than $2 Million; in the Second and Third Causes of Action,
damages to be determined at trial; in the Fourth Cause of Action, an order
revoking or canceling the issuance of additional shares of UTTC(TM) common
stock in excess of the 10,000,000 shares authorized by UTTC(TM)'s original
Certificate of Incorporation; and in the Fifth Cause of Action, an order
revoking or canceling the issuance of the approximately 19,000,000 additional
shares of UTTC(TM) common stock to the Company.
 
  The Company believes that none of the above matters will have a material
adverse effect upon the Company.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
  No matters were submitted to a vote of security holders during the fiscal
year ended March 31, 1997. A Proxy Statement was filed with the SEC on April
20, 1998 notifying stockholders of a Special Meeting of Stockholders to be
held on May 29, 1998 for the purpose of considering and voting upon: (i)
increasing the number of authorized shares of ATG(TM) Common Stock from
20,000,000 to 60,000,000; (ii) increasing the number of authorized shares of
ATG(TM) Preferred Stock from 1,000,000 to 3,000,000; and (iii) authorizing the
issuance of ATG(TM) Common Stock pursuant to certain put rights and upon the
conversion or exercise, as the case may be, of ATG(TM)'s Series D Convertible
Preferred Stock, Series E Convertible Preferred Stock and warrants to purchase
shares of Common Stock issued or issuable pursuant to the Private Equity Line
of Credit Agreement dated April 2, 1998. All three items were approved by the
stockholders at the May 29, 1998 Special Meeting of Stockholders.

ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS
 
  The following discussion of the Company's results of operations and
liquidity and capital resources should be read in conjunction with the
consolidated financial statements and related notes of the Company for the
years ended March 31, 1996, 1997 and 1998. The results for the year ended
March 31, 1998 are not comparable to the prior fiscal year (i) because the
Company established GA, which began to generate revenues in October 1997, and
(ii) because the Company sold, in November 1997, its CSI(R) subsidiary, which
had been the Company's primary source of revenues.
 
REVENUES AND EXPENSES
 
  The Company had consolidated revenues of $3,494,276 for the fiscal year
ended March 31, 1998 which compares with $4,938,330 for the fiscal year ended
March 31, 1997. All but $313,659 of the Company's current fiscal year revenues
and the related "cost of revenues" were generated by CSI(R), and all of the
Company's previous fiscal year revenues were generated by CSI(R). (The
consolidated revenues for last fiscal year do not include $1,386,143 paid by
ATG(TM) and UTTC(TM) to CSI(R) for software engineering services.) During this
fiscal year, the Company sold CSI(R), and continues to seek regulatory
approval to operate its VTS(TM) system and to seek other sources of operating
revenues, including the expansion and development of its subsidiaries.
However, there can be no assurance that the Company will obtain such
regulatory approval, that the company will locate other sources of operating
revenues, or that the Company's subsidiaries, other than GA, will generate
revenues.
 
  During the twelve months ended March 31, 1998, the Company incurred a net
loss of $8,674,902, compared to a loss of $6,842,406 in the prior fiscal year.
These losses include the following significant one-time expenses:
 
  .  $1,804,917 related to the issuance of non-employee stock options to
     consultants and professional advisors. This is a non-cash charge which
     impacts the Company's profit and loss ("P&L") in the current year but
     does not affect the balance sheet (the $1,804,917 reduction in retained
     earnings is offset by a corresponding increase in additional paid-in
     capital to reflect the grant of the options.) The options are not
     registered and are subject to the trading restrictions imposed by SEC
     rules.
 
  .  $385,930 loss on the sale of CSI(R). (On a "cash-on-cash" basis, the
     Company purchased CSI(R) for approximately $1.6 million, sold it for
     $1.7 million, and received $340,000 in cash from CSI(R) per a Tax
     Allocation agreement.)
 
  .  $760,000 settlement of the Rosensaft litigation (see Item 3).
 
  Although the Company reported a higher P&L loss in Fiscal 1998 than in the
prior fiscal year, the "net cash used in operating activities" was less in
fiscal 1998 ($5,749,180) than in fiscal 1997 ($6,377,582). (See "Consolidated
Financial Statement: Statement of Cash Flows")
 
 
GOMEZ ADVISORS
 
  At the beginning of fiscal 1998, the Company established GA. GA has grown
from an initial staff of three to seven employees at fiscal year end. GA
started to generate revenues in October 1997, and these have increased to
$313,659 for the year ended March 31, 1998. Costs of revenues are direct
costs, which include labor costs, subcontract costs, material costs and other
direct costs related to contract revenue and overhead.
 
CSI(R)
 
  CSI(R)'s revenues for the year ended March 31, 1997 increased by 5%,
$2,657,000, to approximately $6,324,000, from approximately $3,667,000 for the
year ended March 31, 1996. This increase was attributable to an increase in
commercial sales of $2,872,000. CSI(R) also recorded revenue of approximately
$1,386,000 from ATG(TM) for the year ended March 31, 1997.
 
                                      12
<PAGE>
 
  Costs of revenues for the year ended March 31, 1997 increased by $1,739,000,
or 58.2%, to approximately $4,725,000, from approximately $2,986,000 for the
year ended March 31, 1996. This change has occurred primarily due to the
higher concentration of commercial sales.
 
  Operating expenses for the year ended March 31, 1997 increased by $120,000,
or 28.0%, to approximately $549,000, from approximately $429,000 for the year
ended March 31, 1996.
 
  Net income for the year ended March 31, 1997 increased by $357,000, or
146.9%, to approximately $600,000, from approximately $243,000 in the year
ended March 31, 1996, based upon increased revenues.
 
SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
 
  During the fiscal year ended March 31, 1998, the Company incurred $5,718,443
of selling, general and administrative ("SG&A") expenses. This compares to the
$3,479,660 of SG&A expenses incurred during the fiscal year ended March 31,
1997. On a per subsidiary basis this fiscal year, ATG(TM) incurred $2,918,187
compared with last year's $2,140,582 of SG&A expense, UTTC(TM) incurred
$1,816,880 compared with last year's $876,069 SG&A expense and GA incurred
$492,901 of SG&A expense. The largest components of ATG(TM)'s increased SG&A
expenses were salaries, professional fees and public company expenses which
include directors and officers insurance.
 
DEVELOPMENT COSTS
 
  During the fiscal year ended March 31, 1998, the Company incurred
development costs of $196,974 which compares with the $3,382,848 of
development costs incurred last fiscal year on a consolidated basis. The
reduction in development costs occurred with the VTS(TM) system being
developed and ready for operation in April 1997. During the previous fiscal
year ended on March 31, 1997, ATG(TM) incurred development costs of $2,049,651
primarily for the design and development of the ATED encryption device and the
encryption client-server. Separately, UTTC(TM) incurred costs of $1,333,197
for the development of the UTS(TM) system.
 
INTEREST EXPENSE
 
  For the year ended March 31, 1998, the Company incurred interest expenses of
$393,813, which included the interest paid on the $3,000,000 in UTTC(TM) notes
payable, interest paid on a loan to CSI(R), and amortization of the deferred
placement expenses associated with its UTTC(TM) notes. This compares to the
interest expense of $39,792 shown last fiscal year.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  For the year ended March 31, 1998, the Company had cash and cash equivalents
of $5,050,680 after giving pro-forma effect to the private placement of Series
D Preferred Stock consummated on April 3, 1998 and after giving effect to the
additional Series B Preferred issuance. This compares to the cash and cash
equivalents of $2,691,854 in the last fiscal year after giving pro-forma
effect to the UTTC(TM) private placement that was consummated in April 1997.
Management expects to raise additional capital for the development of new
online transactional products for UTTC(TM), GA and ATG(TM) from the Series E
Equity Line of Credit or other sources. The Company has committed $1.5 million
of any such additional capital to the expansion of GA to complete its initial
business strategy. Management also expects to generate revenues from the
VTS(TM) system once regulatory approval has been obtained and the Company can
begin marketing the product to the professional investment community. However,
there can be no assurance that approval will be received or when such approval
will be received.
 
  Based upon the Company's current plan of operations, it is anticipated that
the net proceeds from the private placement of Series D Preferred completed in
April 1998 and the Series E Preferred together with the Put (when and if
exercised), will provide sufficient working capital for at least the next 18
months. The Company may need
 
                                      13
<PAGE>
 
additional financing in the future if (i) the Company experiences unexpected
costs, (ii) there is a delay in the introduction of the UTS(TM) system, (iii)
the Company fails to develop successfully the market for its
products, (iv) other opportunities arise which require significant investment,
or (v) if the net proceeds from the Series D Preferred and Series E Preferred
private placements prove to be insufficient for the Company's continued
operations. In addition, the Company may require additional financing to
complete any acquisition it may undertake. If financing is required, such
financing may be raised through additional equity offerings, joint ventures or
other collaborative relationships, borrowings and other sources. There can be
no assurance that additional financing will be available or, if it is
available, that it will be available on acceptable terms. If additional funds
are raised through the issuance of additional equity securities, the
percentage ownership of the then current stockholders of the Company may be
reduced and such equity securities may receive rights, preferences or
privileges senior to those of the holders of Common Stock.
 
CAPITAL EXPENDITURES
 
  During the current fiscal year ended March 31, 1998, the Company spent
$348,392 for the acquisition of capital equipment. This compares with the
$1,104,336 the Company spent for the acquisition of capital equipment
(primarily computer hardware and software for the UTS(TM) system) and for
leasehold improvements during the previous fiscal year.
 
TAX ALLOCATION AGREEMENT
 
  On or about March 27, 1997, the Company entered into an agreement with each
of its subsidiaries at the time, CSI(R) and UTTC(TM) (together with the
Company, the "Affiliated Group"), providing for the allocation of the
consolidated tax liability of the Affiliated Group among its members, for
reimbursing the Company for payment of such tax liability, for compensating
any party for use of its losses or tax credits, and for the allocation and
payment of any refund arising from a carryback of losses or tax credits from
subsequent tax years. The tax allocation agreement with CSI(R) was terminated
on its sale by the Company.

                         INDEPENDENT AUDITOR'S REPORT
 
To the Board of Directors
The Ashton Technology Group, Inc.
 
  We have audited the accompanying consolidated balance sheet of The Ashton
Technology Group Inc. and Subsidiaries as of March 31, 1998 and the related
consolidated statements of operations, stockholders' equity, and cash flows
for each of the two years in the period then ended. We have also audited the
pro forma consolidated balance sheet which gives effect to the receipt of
proceeds from issuance of preferred stock as described in Note 15 to the
consolidated financial statements. These financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of The Ashton
Technology Group, Inc. and Subsidiaries as of March 31, 1998 and the results
of their operations and their cash flows for each of the two years in the
period then ended in conformity with generally accepted accounting principles.
Also, in our opinion, the pro forma balance sheet presents fairly the
financial position of The Ashton Technology Group, Inc. and Subsidiaries as it
would have appeared at March 31, 1998 had the transaction described in Note 15
been consummated at that date.

              THE ASHTON TECHNOLOGY GROUP, INC. AND SUBSIDIARIES
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. ORGANIZATION, PRESENTATION, PRINCIPAL BUSINESS ACTIVITY AND SIGNIFICANT
   ACCOUNTING POLICIES:
 
 The accompanying consolidated financial statements include the accounts of
The Ashton Technology Group, Inc. ("Ashton") and its Subsidiaries, Universal
Trading Technologies Corporation ("UTTC(TM)"), and Gomez Advisors, Inc., a
company formed in May 1997 ("Gomez"), (collectively the "Company"). All
significant intercompany transactions and balances have been eliminated in
consolidation.
 
  On May 2, 1996, Ashton purchased sufficient shares of Class A voting and
Class B nonvoting common stock of Computer Science Innovations inc. ("CSI(R)")
to enable Ashton to own 80% of each class of CSI(R)'s common stock, giving
Ashton a controlling interest in CSI(R). On November 4, 1997, Ashton sold
CSI(R) (see Note 9). The results of operations of CSI(R) are included in the
accompanying consolidated financial statements since May 2, 1996, the date of
acquisition, through November 4, 1997, the date of disposition of CSI(R). In
May 1997, the Company formed a wholly owned subsidiary, Gomez. Gomez provides
banks, broker-dealers, insurance companies and other financial intermediaries
with advice concerning the business potential of the Internet as a tool for
use in marketing and in the interactive distribution of financial products.
The range of services provided includes strategy development, marketing,
product and interface design and implementation planning. Gomez recognizes
revenue when services are performed. The results of operations of Gomez are
included from the date of formation.
 
  The Company was founded to take advantage of opportunities in the rapidly
evolving businesses of Internet and electronic commerce through the
application of its skills and advanced technologies in securities trading and
information security. The Company designs, develops and markets online
transactional systems, especially for the securities industry, and information
security technologies. Ashton has designed and developed the Ashton Technology
Encryption Device ("ATED") and UTTC(TM) has designed and developed the
Universal Trading System ("UTS(TM)").
 
  CSI(R)'s revenue on time and materials-type contracts is recognized as work
performed. Revenue from cost-reimbursement contracts is recorded as costs
incurred and includes estimated earned fees in the proportion that costs
incurred to date bear to total estimated costs. CSI(R) recognizes revenue from
long-term fixed-price contracts on the percentage-of-completion method,
measured by the percentage of contract costs incurred to date to estimated
total contract costs for each contract.
 
  CSI(R)'s cost of revenue includes all direct material and labor costs and
those indirect costs related to contract performance. Provisions for estimated
losses on uncompleted fixed-price contracts are made in the period in which
such losses are first estimated. The cumulative effect of revisions to
estimated total contract costs and revenue is recorded in the period in which
the facts requiring the revision become known. Claims, including change
orders, are reflected at estimated recoverable amounts. An allowance for
doubtful accounts is recorded in the period in which such accounts are
determined to be uncollectible.
 
  Development costs are expensed as incurred until technical feasibility is
obtained. Development costs incurred subsequent to technical feasibility are
capitalized and amortized on a straight-line basis over the estimated economic
life of the product of 18 months.
 
  At each balance sheet date, the capitalized computer software costs are
compared to the net realizable value of the related product. The net
realizable value is the estimated future gross revenue from the related
product reduced by the estimated future costs of completing and disposing of
such product. In the event that the unamortized capitalized computer software
costs exceed the net realizable value of the related product, such excess
amount is to be written off.
 
  Advertising and marketing costs are charged to operations when incurred.
These costs amounted to approximately $175,000 and $245,000 for the years
ended March 31, 1997 and 1998, respectively.

              THE ASHTON TECHNOLOGY GROUP, INC. AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.
 
  The Company considers highly liquid investments with an original maturity of
three months or less to be cash equivalents.
 
  In 1998, the Company adopted Statement of Financial Accounting Standards
("SFAS") No. 128, Earnings per Share. The adoption of this statement does not
change net loss per common share for the year ended March 31, 1997. Net loss
per common share is computed using the weighted-average number of shares
outstanding.
 
  In June 1997, the Financial Accounting Standards Board (the "FASB") issued
SFAS No. 130, Reporting Comprehensive Income, and SFAS No. 131, Disclosures
about Segments of an Enterprise and Related Information. In February 1998, the
FASB issued SFAS No. 132, Employer's Disclosures about Pensions and Other
Postretirement Benefits. SFAS No. 130 establishes new standards for reporting
and displaying comprehensive income and its components. SFAS No. 131 requires
disclosure of certain information regarding operating segments, products and
services, geographic areas of operation and major customers. SFAS No. 132
revises employer's disclosures about pensions and other postretirement benefit
plans. Adoption of these statements is expected to have no significant impact
on the Company's consolidated financial position, results of operations or
cash flows.
 
  Depreciation of property and equipment is provided for using the straight-
line method over the estimated useful life of the related assets. Amortization
of leasehold improvements is provided for using the straight-line method over
the term of the lease.
 
  The Company maintains life insurance policies on its key officers and
employees in the aggregate amount of $8,600,000.
 
  In 1997, the Company adopted SFAS No. 123, Accounting for Stock-Based
Compensation. The Company has elected to apply APB Opinion No. 25 and related
interpretations in accounting for its stock options issued to employees and
has adopted the disclosure-only provisions of SFAS No. 123.
 
  In 1998, the Company purchased a 1.5% interest in E. Com International, Inc.
for $105,000. The investment is accounted for on the cost method.
 
2. PROPERTY AND EQUIPMENT:
 
  Property and equipment, at cost, consists of the following:

private placement. Each unit consisted of a $49,000 10% nonconvertible
promissory note due in April 1997 and a $1,000 10% convertible promissory note
due in October 1998. The $1,000 convertible notes were convertible into
warrants to purchase 20,000 shares of common stock through October 1998 at $8

6. INITIAL PUBLIC OFFERING:
 
  On May 2, 1996, the Company completed an Offering of 2,150,000 shares of
common stock at an offering price of $4.50 per share and 2,150,000 warrants at
$.25 per warrant. The common stock and the warrants are separately tradable.
The Company granted to the underwriters the right to exercise over-allotment
options of 322,500 shares of common stock and/or 322,500 warrants at the
Offering price, within 45 days of May 2, 1996. On May 7, 1996, the
underwriters exercised the over-allotment options and offered an additional
322,500 shares of common stock and 322,500 warrants to the public at $4.50 per
share and $.25 per warrant. As a result of the Offering, the Company received
net proceeds of approximately $10,395,000 and increased its total shares of
common stock and warrants outstanding by 2,472,500 each. The net proceeds from
the Offering were used to

              THE ASHTON TECHNOLOGY GROUP, INC. AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
repay all notes payable to stockholders, certain notes payable and related
accrued interest in existence through the date of the Offering and provided
working capital. The net proceeds were also used to purchase the additional
shares of CSI(R) stock as described in Note 9.
 
  Concurrent with the Offering, the Company registered 760,000 additional
warrants to purchase common stock. Such warrants are identical to the warrants
described above and were issuable automatically upon the completion of the
Offering in exchange for the already existing outstanding common stock
warrants.
 
7. STOCKHOLDERS' EQUITY:
 
  In 1998, the Company completed a series of private offerings and an exchange
offering pursuant to which it issued to certain investors (i) 250,000 shares
of its Series A Convertible PIK Preferred Stock (with a liquidation preference
of $10.00 per share) (the "Series A Preferred"); (ii) 162,500 shares of its
Series B Convertible Preferred Stock (with a liquidation preference of $10.00
per share) ("Series B Preferred"); and (iii) exchanged 297,500 shares of its
Series B Preferred for $2,975,000 of convertible and nonconvertible notes
issued by UTTC(TM) (see below). The Series A Preferred pays cumulative
dividends semiannually at an annual rate of $.50 per share payable in
additional shares of Series A Preferred until February 15, 2000. At any time
after February 15, 1998, each holder of shares of Series A Preferred will have
the right to convert each share of Series A Preferred into: (i) ten shares of
common stock of Ashton, and (ii) one two-year warrant to purchase three shares
of the common stock, par value $.01 per share, of UTTC(TM) (the "UTTC(TM)
Common Stock"), with an exercise price of $.75 per share, subject to
adjustment. The Series B Preferred pays cumulative dividends semiannually at
an annual rate of $.90 per share. At any time after June 30, 1998, each holder
of shares of Series B Preferred will have the right to convert each share of
Series B Preferred into: (i) six shares of common stock, and (ii) one two-year
warrant to purchase two shares of UTTC(TM) Common Stock, with an exercise
price of $.75 per share, subject to adjustment.
 
  Dividends in arrears amounted to $47,705 and $60,044 for Series A Preferred
and Series B Preferred, respectively.
 
  In addition, in January 1998, the Company completed the sale of 100,000
shares of its Series C Convertible Preferred Stock to a group of foreign
investors (the "Series C Investors"), with a liquidation preference of $10.00
per share (the "Series C Preferred"), for an aggregate purchase price of
$1,000,000. Holders of the Series C Preferred will have the right to convert
each share of Series C Preferred into one share of common stock at the
conversion price which shall be equal to the following: (i) if the Market
Price (as hereinafter defined) on the Conversion Date (as hereinafter defined)
is less than $1.8774, the conversion price is equal to the lesser of 75% of
the Market Price at the Conversion Date or $1.2516; and (ii) if the Market
Price at the Conversion Date is equal to or greater than $1.8774, the
conversion price is equal to $1.2516 plus 50% of the difference between the
Market Price at the Conversion Date and $1.8774. The Market Price shall mean
the average of the closing bid prices per share of the common stock over the
five consecutive trading days preceding the Conversion Date. The Conversion
Date shall mean the date the holder elects to have shares converted into
common stock. In addition, the Series C Investors will receive warrants
exercisable into an aggregate of 100,000 shares of common stock at an exercise
price of 105% of the Market Price for a period of five years. In connection
with the sale, the Company has agreed to pay a placement fee to a placement
agent of $50,000 and to transfer to it 5,000 shares of the Series C Preferred
and a warrant to purchase 100,000 shares of common stock at an exercise price
of 105% of Market Price for a period of five years. In March 1998, 50,000
shares of Series C Preferred were converted into 281,071 shares of common
stock. In addition, subsequent to March 31, 1998, the remaining 55,000 shares
of Series C Preferred were converted into 314,343 shares of common stock.
 
  At the time of issuance, the preferred stock described above was convertible
at prices below the market price of the underlying common stock. The
beneficial conversion feature represented by the intrinsic value is calculated
as the difference between the conversion price and the market price of the
underlying common stock

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
multiplied by the number of shares to be issued upon conversion. The
beneficial conversion feature is recognized as a return to the preferred
stockholders over the minimum period in which the preferred stockholders can
realize that return. At March 31, 1998, the beneficial conversion feature
amounted to $1,643,900, $212,637 and $349,943 for Series A Preferred, Series B
Preferred and Series C Preferred, respectively.
 
  The Company received net proceeds from the above transactions of
approximately $3,734,000 after deducting issue costs of approximately
$1,146,000.
 
  In April 1997, UTTC(TM) completed a private placement of $3,000,000 in
notes, consisting of $2,550,000 nonconvertible and $450,000 convertible notes,
to accredited investors. The Company received net proceeds of approximately
$2,600,000 after deducting debt issue costs of approximately $400,000. As
described above, $2,975,000 of these notes were exchanged for Series B
Preferred.
 
  At March 31, 1998, notes payable consist of $21,250 nonconvertible and
$3,750 convertible UTTC(TM) notes. The convertible notes are convertible into
3,750 shares of UTTC common stock. The notes bear interest at 9% per annum
payable on January 31, annually, and are due January 31, 1999.
 
  In February 1998, the Company entered into a consulting agreement whereby
the Company issued 300,000 shares of common stock, with a fair market value of
$475,125, in exchange for promotional services through February 1999. The
consulting costs will be amortized over the term of the agreement. For the
year ended March 31, 1998, the Company charged $39,844 to operations and
recorded a deferred consulting expense of $438,281 as a reduction to
stockholders' equity at March 31, 1998.
 
  In May 1998, the Company's stockholders authorized an increase in the number
of shares of common stock from 20,000,000 to 60,000,000 and in the number of
shares of preferred stock from 1,000,000 to 3,000,000.
 
8. DEFINED CONTRIBUTION PLAN:
 
  The Company maintains a defined contribution plan under Section 401(k) of
the Internal Revenue Code covering all qualified employees. The Company may
make nonmandatory contributions. Certain officers of the Company serve as
trustees of the plan. No contributions were made during the years ended March
31, 1997 and 1998.

  On November 4, 1997, Ashton sold CSI(R) to a trust created by the Computer
Science Innovations Inc. Leveraged ESOP for $1,723,000. The Company received
$600,000 in cash, a $594,125 five-year 8 1/4% note and the forgiveness of
$528,875 due to CSI(R), which included $28,875 of accrued interest. The sale
resulted in a loss of $385,930, which is included in the accompanying
consolidated statement of operations. Based on rates of return currently
available to the Company for investments with similar terms and maturities,
the fair value of the note receivable approximates the carrying amount.
 
10. INCOME TAXES:

  The Company has net operating loss carryforwards at March 31, 1998 of
approximately $11,800,000, which will begin to expire in 2011, available to
reduce future federal taxable income. Additionally, the income tax basis of
intangibles and nonqualified options exceeds the basis for financial reporting
purposes by approximately $1,400,000 and $2,600,000, respectively. The
carryforwards and the temporary difference result in a deferred tax asset of
approximately $6,260,000 at March 31, 1998 for which the Company has provided
a full valuation allowance due to the uncertainty about the future realization
of this tax benefit.
 
  The components of deferred income taxes at March 31, 1998 were as follows:

  The Company files a consolidated federal income tax return. In 1997, Ashton
entered into an agreement with CSI(R) and UTTC(TM). The agreement provides
that any member of the group which has taxable income must compensate any
other member for the use of net operating losses and tax credits. The
agreement with CSI(R) was terminated upon disposition.

  The leases are subject to escalation for the Company's share of increases in
real estate taxes and other operating expenses. In addition, the Company
leases office facilities on a month-to-month basis. Rent expense for the years
ended March 31, 1997 and 1998 totaled approximately $390,000 and $253,000,
respectively.
 
  The Company has employment agreements which require the Company to pay
approximately $672,000 through September 1999.
 
  In September 1995, UTTC(TM) entered into an agreement with the Philadelphia
Stock Exchange ("PHLX") whereby PHLX has agreed to employ UTTC(TM)'s UTS(TM)
on its equity trading floor. In connection with this agreement, UTTC(TM) is
required to reimburse PHLX up to $100,000 for the first year of the agreement
for marketing costs incurred by PHLX. UTTC(TM) is also required to assume up
to $200,000 of PHLX's initial technology development costs in implementing the
UTS(TM). UTTC(TM) is required to contribute to a PHLX administered "claim
fund" for potential claims relating to the UTS(TM) operations. UTTC(TM) is
required to contribute $100,000 after commencement of the UTS(TM) trading and,
if necessary, to make additional contributions of up to $100,000 per year to
such claim fund. PHLX is also entitled to receive an annual

royalty from UTTC(TM) of 3% of annual gross revenue based on UTTC(TM)'s
average revenue in the first three years of operations for each year the PHLX
agreement is in effect. These payments are required to begin at the end of the
second full year of operation and continue for the life of the PHLX agreement.
 
  On January 30, 1997, Ashton, along with UTTC(TM), Fredric W. Rittereiser
("Rittereiser") and Dover (of which Rittereiser is the chairman) entered into
a settlement agreement ("Settlement Agreement dated January 30, 1997") related
to a dispute with David N. Rosensaft ("Rosensaft") (a cofounder of UTTC(TM))
under which a consulting agreement among Ashton, UTTC(TM) and Rosensaft dated
January 19, 1996 was deemed to be void ab initio and each of the parties
released and discharged each of the other parties from any and all agreements
and claims which any of them have against any of the other parties. The
Settlement Agreement dated January 30, 1997 granted Rosensaft registration
rights under the Securities Act of 1933, as amended (the "Securities Act")
under certain terms and conditions for the 333,333 shares of UTTC(TM) common
stock that he owns. Also on January 30, 1997, Ashton, Dover, Rittereiser and
Rosensaft entered into a Stock Purchase Agreement under which Dover and
Rittereiser or his or its designee, agreed to purchase the 750,000 shares of
Ashton common stock owned by Rosensaft on April 10, 1997 for a total purchase
price of $2,000,000 and Ashton granted Dover and Rittereiser or his or its
designees, registration rights under the Securities Act under certain
conditions for the 750,000 shares. On or about April 10, 1997, Ashton advised
Rosensaft that the Rosensaft agreement was null and void and Rittereiser and
Dover declined to purchase the 750,000 shares.
 
  On May 1, 1997, Rosensaft commenced an action in the United States District
Court for the Southern District of New York entitled David N. Rosensaft vs.
The Ashton Technology Group, Inc., UTTC(TM), Dover and Fredric Rittereiser
(collectively the "defendants") No. 97 Civ. 3138, asserting 10 claims against
the defendants including breach of contract and securities fraud and seeking,
inter alia, specific performance of the Settlement Agreement dated January 30,
1997, between and among the parties or in the alternative, actual and
consequential damages in an amount to be proved at trial in addition to
punitive damages. On June 11, 1997, Rosensaft served a First Amended Complaint
adding three additional claims against the defendants, relating to Ashton's
refusal to allow Rosensaft's sale of his Ashton shares.
 
  On June 26, 1997, the defendants filed their answers and counterclaims
generally denying the allegations of the First Amended Complaint and alleging
six counterclaims against Rosensaft including that (i) Rosensaft acquired
1,100,000 shares of Ashton common stock from Ashton on the basis of false and
misleading statements and common law fraud, and (ii) Rosensaft breached his
January 19, 1996 consulting agreement with the Company (the "Agreement") by
(a) failing to carry out his duties as a consultant under the Agreement, (b)
violating the provisions of the Agreement restricting his use of confidential
information of the Company, (c) failing to adhere to the noncompetition
provisions of the Agreement, (d) misappropriating for himself the property
rights of UTTC(TM) relating to the Company's UTS(TM) and (e) failing to return
to UTTC(TM) and/or Ashton valuable property and information, including
confidential documents and computer equipment belonging to UTTC(TM) and/or
Ashton.
 
  On April 10, 1998, the Company and Dover entered into a settlement agreement
pursuant to which Rosensaft is to receive $1,133,000 in settlement of the
above claims and counterclaims. The Company's portion of the settlement, which
amount has been accrued and charged to operations for the year ended March 31,
1998 is $760,000.
 
  On May 29, 1998, Rosensaft filed a complaint alleging that UTTC(TM) had
improperly amended its certificate of incorporation increasing the number of
authorized shares of UTTC(TM) common stock. Rosensaft is asserting inter alia
claims regarding (i) breach of contract, (ii) improper dilution of Rosensaft's
ownership share of UTTC(TM), (iii) breach of fiduciary duty, (iv) fraud, and
(v) violations of Delaware corporate law. The Company and counsel for the
Company are of the opinion that the claims are unfounded and without merit.

  On October 22, 1996, the Company entered into a settlement agreement (the
"Settlement Agreement") related to a dispute involving Robert A. Eprile, John
A. Blohm, Rittereiser, Dover, F.E. Weimmer, Jr., F.E. Weimmer, Sr., F.E.
Rittereiser, Sr. and Thomas Rittereiser, as trustee for Alexis J. Rittereiser,
Amanda Weimmer and John Weimmer, Raymond T. Tate ("Tate"), Helen J. Tate, as
trustee for the Andrew Patrick Tate Trust, Helen J. Tate, as trustee for the
Susan Katherine Tate Burrowbridge Trust and Helen J. Tate, as trustee for the
Elizabeth Tate Winters Trust (collectively the "Tate Trusts"). The Settlement
Agreement resolved all differences among the parties thereto, and all parties
to the Settlement Agreement agreed to release each of the other parties from
any and all actions or claims arising out of or in connection with the matters
covered by the Settlement Agreement. Pursuant to the Settlement Agreement, on
October 22, 1996, Tate resigned from his position as director of the Company
and its Subsidiaries and all officer positions held by him in the Company and
its Subsidiaries. Pursuant to the Settlement Agreement, on October 22, 1996,
the board of directors of the Company elected Fred S. Weingard, executive vice
president of UTTC(TM), to fill the vacancy on the Company's board of directors
created by the resignation of Tate.
 
  Pursuant to the Settlement Agreement and in consideration of the payment of
$250,000 on October 22, 1996, Helen J. Tate as trustee for the Tate Trusts
granted to Rittereiser or his designee the option (the "Call Option"),
exercisable at any time from April 2, 1997 through June 2, 1997, to purchase
1,000,000 shares of the Company's common stock, par value $.01 per share (the
"Tate Common Stock"), from the Tate Trusts for a total purchase price of
$4,500,000. Pursuant to the Settlement Agreement and in consideration for $1,
Rittereiser granted Tate the option (the "Put Option"), exercisable at any
time during the five business days following the exercise of the Call Option,
to require Rittereiser to purchase from Tate the 107,500 shares of Tate Common
Stock owned, beneficially or otherwise, by Tate for a total purchase price of
$483,750. Rittereiser did not exercise the Call Option prior to its
expiration.
 
  In addition, on October 22, 1996, Tate and the Company also entered into a
license agreement (the "License Agreement"). Under the terms of the License
Agreement, the Company granted Tate a perpetual, worldwide license, at his own
cost, to use, sublicense, reproduce and make derivative works and enhancements
of the technology used by the Company to develop the ATED, including the ATED
Key Management System, encryption software and cryptoserver technology (the
"Licensed Technology") in any field of use other than the Financial Services
Industry (as such term is defined in the License Agreement). In consideration
for granting the license, Tate (or his permitted assigns under the License
Agreement) must pay a perpetual annual royalty to the Company equal to 2% of
the total gross revenue earned from the use of the Licensed Technology. Tate's
right to use the Licensed Technology will be exclusive, provided Tate pays to
the Company a cumulative license fee of at least $100,000 by October 22, 2000.
The license fee will be reduced by the total amount of royalties paid to the
Company. Tate may assign the license to any person or entity controlled by
Tate.
 
  Additionally, the Company and Tate entered into a consulting agreement,
dated October 22, 1996 (the "Consulting Agreement"). Under the terms of the
Consulting Agreement, the Company retained Tate to act as a consultant to
CSI(R) for the period from October 22, 1996 to December 31, 1998. As
compensation for such services, for the period from October 22, 1996 through
December 31, 1996, the Company paid Tate $40,000. For the period from October
22, 1996 through December 31, 1998, the Company will also pay to Raymond Tate
Associates, Inc. $120,000 per annum which was charged to operations during the
year ended March 31, 1997 and is included in corporate restructuring costs.
Tate also agreed not to compete with the Company in the Financial Services
Industry (as such term is defined in the Consulting Agreement) during the term
of the Consulting Agreement.
 
  On October 24, 1996, the Securities and Exchange Commission (the "SEC")
commenced a private investigation concerning the circumstances under which
Ashton's subsidiary, UTTC(TM), obtained a contract with PHLX to develop and
install an electronic trading and pricing system. Ashton provided testimony to
the SEC

on February 12, 1997 through its chairman, Robert Eprile, and has not been
contacted about the matter since that date. In March 1997, the SEC directed
PHLX to make certain changes in its governance procedures and in April 1997
PHLX announced a reorganization of its board of governors and changes in its
governance procedures.
 
  In addition to the above claims, the Company is involved in various claims
and legal actions arising in the ordinary course of business. Management is of
the opinion that the ultimate outcome of these matters would not have a
material adverse impact on the financial position of the Company or the
results of its operations.
 
15. SUBSEQUENT EVENTS:
 
  On April 3, 1998 (the "Subscription Date"), the Company entered into a
Private Equity Line of Credit Agreement (the "Private Equity Agreement") with
a group of accredited investors (the "Private Equity Investors") which
provides for an aggregate commitment of $18,000,000 to the Company. On the
Subscription Date the Private Equity Investors purchased three shares of
Series D Convertible Preferred Stock (the "Series D Preferred") with a
liquidation preference of $1,000,000 per share for an aggregate purchase price
of $3,000,000 and the Company agreed to promptly file a registration statement
(the "Registration Statement") under the Securities Act, registering shares of
the Company's common stock (the "Registered Common Stock") issuable in
connection with the transactions contemplated by the Private Equity Agreement.
The Private Equity Agreement provides that within five days after the
Registration Statement has been filed and subject to the satisfaction of
certain other conditions, the Private Equity Investors will purchase two
shares of Series E Convertible Preferred Stock (the "Series E Preferred") with
a liquidation preference of $1,000,000 per share for an aggregate purchase
price of $2,000,000. Following the purchase of the Series E Preferred and
subject to the satisfaction of certain other conditions, the Company may from
time to time put (each, a "Put") to the Private Equity Investors shares of the
Registered Common Stock for an aggregate Put price of $13,000,000. The Put
price per share is an amount equal to 85% of the average of the lowest bid
prices of such Registered Common Stock over the seven-day period beginning
three days before and ending three days after the Company gives notice of a
Put. On the completion of each Put, the Company has agreed to pay the
placement agent an amount equal to 5% of the proceeds of such Put.
 
  The Private Equity Investors are not obligated to purchase the Series E
Preferred or any Put shares unless, among other things, (i) the Company has
received the required approval, (ii) the Registration Statement is filed (the
Registration Statement must be effective in order for the Private Equity
Investors to be obligated to purchase any Put shares), (iii) the Company is
listed and trading on a national exchange or quotation system, (iv) the
closing bid price of the common stock on the day immediately preceding such
purchase is at least $1.50 per share, and (v) the common stock has traded at a
volume of at least 25,000 shares a day for the 30 trading days preceding such
purchase.
 
  The Series D Preferred may not be converted into common stock until the
earlier of (i) 60 days following the Subscription Date or (ii) the
Registration Statement has been filed. The conversion price of the Series D
Preferred is an amount equal to 75% of the Market Price. The conversion price
of the Series E Preferred is 80% of the Market Price. Each of the Series D
Preferred and Series E Preferred is entitled to a cumulative dividend of 8%
per annum on its respective liquidation preference.
 
  On the Subscription Date the Private Equity Investors received warrants
(each, a "Warrant") to purchase up to an aggregate of 250,000 shares of
Registered Common Stock and will receive additional Warrants to purchase up to
an aggregate of 100,000 of such shares on the completion of the purchase of
the Series E Preferred. The Warrants are exercisable for five years at an
exercise price of 120% of average closing bid price of the common stock over
the five trading days preceding the Subscription Date.

  On the Subscription Date, the Company paid the placement agent a fee of (i)
$150,000, (ii) .15 shares of Series D Preferred, (iii) a Warrant, on the same
terms as the Warrants issued to the Private Equity Investors, to purchase up
to 190,000 shares of Registered Common Stock and (iv) 20,000 shares of common
stock.
 
  In addition, upon the completion of the purchase of Series E Preferred, the
Company will pay a placement fee of (i) 5% of the purchase proceeds and (ii)
 .10 shares of Series E Preferred and a warrant to purchase 60,000 shares of
common stock.
 
  In April 1998, the Company issued 127,500 shares of Series B Preferred and
3.15 shares of Series D Preferred. The Company received net proceeds from the
above transactions of approximately $3,790,000 after deducting issue costs of
approximately $485,000 of which $200,000 was paid to a member of the Company's
board of directors.
 
  The accompanying pro forma balance sheet presents the financial position of
the Company as it would have appeared at March 31, 1998 had the additional
Series B Preferred and Series D Preferred been issued on that date. The
issuance included a beneficial conversion feature aggregating $1,977,998.
 
  In April 1998, UTTC(TM) formed a wholly owned subsidiary, REB Securities,
Inc. ("REB"). REB will operate as a registered broker-dealer.
 
  Subsequent to March 31, 1998, the Company formed a wholly owned subsidiary,
Electronic Market Center, Inc. ("EMC"). EMC will develop and operate a
transactional Web site for the financial community.

that time, the Board of Directors of the Company decided to engage a Maryland-
based accounting firm. GGK's reports on the financial statements of the
Company did not contain any adverse opinion or disclaimer of opinion, nor were
they qualified or modified as to uncertainty, audit scope or accounting
principles. There were no disagreements with GGK on any matter of accounting
principles or practices, financial statement disclosure or auditing scope or
procedure, which, if not resolved to the satisfaction of GGK, would have
caused it to make reference to the subject matter of the disagreement(s) in
connection with its report.
 
  The Baltimore, Maryland office of Arthur Andersen LLP ("Andersen") was
engaged as the Company's independent public accountants effective June 3, 1996
and performed the audit for the fiscal year ended March 31, 1996. However,
after the principal executive offices of the Company were relocated to
Philadelphia, Pennsylvania, the Company decided to re-engage GGK. The decision
to change accountants was approved by the Company's Board of Directors. On
April 30, 1997, Andersen was dismissed as the principal independent
accountants engaged in auditing the financial statements of the Company.
Andersen's report on the financial statements of the Company for the 1996
fiscal year (which was the only year for which Andersen acted as the Company's
principal independent accountants) did not contain an adverse opinion or a
disclaimer of opinion and was not modified as to uncertainty, audit scope or
accounting principles. There were no disagreements with Andersen on any matter
of accounting principles or practices, financial statement disclosure or
auditing scope or procedure, which, if not resolved to the satisfaction of
Andersen, would have caused it to make reference to the subject matter of the
disagreement(s) in connection with its report.
 
  On April 30, 1997, GGK was re-engaged as principal independent accountants
to audit the financial statements of the Company and its subsidiaries. As
noted, GGK was the Company's auditor for its fiscal year ended March 31, 1995
and for Ashton's Offering.

stockholders and of the board and shall be an ex officio member of all
committees of the board.  He shall perform all duties incident to the office of
chairman of the board and such duties as may from time to time be assigned to
him by the board of directors.

          The president shall be the chief executive officer of the Corporation
and shall have the general and active supervision and direction over the
business operations and affairs of the Corporation and over its several
officers, agents and employees, subject, however, to the direction of the
chairman of the board and the control of the board of directors.  At the request
of the chairman of the board, or in the case of his absence or inability to act,
the president shall perform the duties of the chairman of the board, including
presiding at meetings of stockholders and directors and when so acting, shall
have all the powers of, and be subject to all the restrictions upon, the
chairman of the board.  In general, the president shall have such other powers
and shall perform such other duties as usually pertain to the office of
president or as may be assigned to him, from time to time, by the board, the
chairman of the board or these by-laws."

                                                  -----------                 
organized and existing under the General Corporation Law of the State of
Delaware (the "DGCL"), does hereby certify that pursuant to the provisions of
               ----                                                          
Section 151 of the DGCL, the Board of Directors of the Corporation, at a meeting
duly convened on September 11, 1997 at which a quorum was present at all times,
adopted the following resolution, which resolution remains in full force and
effect as of the date hereof:

          WHEREAS, the Board of Directors of the Corporation is authorized,
within the limitations and restrictions stated in the Corporation's Certificate
of Incorporation, to fix by resolution or resolutions the designation of each
class or series of Preferred Stock (the "Preferred Stock") and the voting
                                         ---------------                 
powers, and any designations, preferences, and relative, participating, optional
or other special rights of any such class or series of Preferred Stock, as well
as such other provisions with regard to redemption (at the option of the holders
thereof and/or at the option of the Corporation), dividends, dissolution or the
distribution of assets, conversion or exchange, and any qualifications or
restrictions thereof or such other subjects or matters as shall be stated and
expressed in the resolution or resolutions providing for the issue of such stock
adopted by the Board of Directors; and

          WHEREAS, it is the desire of the Board of Directors of the
Corporation, pursuant to such authority, to authorize and fix the terms of the
series of Preferred Stock designated as Series A Convertible PIK Preferred Stock
(the "Series A Preferred"):
      ------------------   

          NOW THEREFORE, be it resolved, that the terms and provisions of such
series and all other right or preferences granted to or imposed upon such series
or the holders thereof are as herein set forth:

                                       2
<PAGE>
 
          1.   Rank. The Series A Preferred shall, with respect to dividend
               ----                                                        
rights or rights upon liquidation, dissolution and winding-up of the
Corporation, rank pari passu with all other series of preferred stock or other
class of security expressly ranking pari passu ("Pari Passu Classes") with the
                                                 ---- -------------           
Series A Preferred of the Corporation (including, without limitation, the Series
B Convertible Preferred Stock of the Corporation) and prior to all series or
classes of Common Stock of the Corporation ("Common Stock"). Nothing contained
                                             ------------                     
herein shall be of Common Stock of the Corporation ("Common Stock"). Nothing
contained herein shall be construed to prohibit the Corporation from authorizing
or issuing, in accordance with its Certificate of Incorporation and By-Laws, as
the same may be amended and in effect from time to time, any classes or series
of equity securities of the Corporation ranking senior to or pari passu with the
Series A Preferred with respect to dividend rights or rights upon liquidation,
dissolution and winding-up of the Corporation or both.

          2.   Dividends. (a) The holders of the shares of the Series A
               ---------                                               
Preferred shall be entitled to be paid, when, as and if declared by the Board of
Directors of the Corporation out of funds legally-available for the payment of
dividends, dividends at an annual rate of $0.50 per share payable semiannually
February 15 and August 15, of each year commencing February 15, 1998 ( a
"Dividend Payment Date"). Such dividends shall, if declared, be paid to holders
of the Series A Preferred at the close of business on February 15 and August 15
of each year, commencing February 15, 1998. Each of semi-annual dividends
(whether in cash or stock) shall be fully cumulative and shall accrue (whether
or not declared), without interest, from the date of the immediately preceding
Dividend Payment Date, except with respect to the first dividend payment which
will accrue from the date of issuance of the Series A Preferred. Any dividend
payments made with respect to the Series A Preferred prior to and including
February 15, 2000 (the "Pay-In-Kind Period") may be made, at the option of and
                        ------------------                                    
in the sole discretion of the Board of Directors, in cash or by issuing
additional fully paid and nonassessable shares of Series A Preferred at the rate
of 0.05 of one share for each $1.00 of such dividend not paid in cash, and the
issuance of such additional shares shall constitute full payment of such
dividend; provided, however, that if the Corporation shall fail to pay a
          --------  -------                                             
dividend payment in cash during the Pay-In-Kind Period, then the Corporation
shall make such dividend payment in additional shares.

               (b)  Each fractional share of Series A Preferred outstanding
shall be entitled to a ratably proportionate amount of all dividends accruing
with respect to each outstanding share of Series A Preferred pursuant to Section
2(a) hereof, and all such dividends with respect to such outstanding fractional
shares shall be fully cumulative and shall accrue (whether or not declared),
without interest, and shall be payable in the same manner and at the such times
as provided in Section 2(a) hereof with respect to dividends on each outstanding
share of Series A Preferred.

          3.   Liquidation Preference.
               ---------------------- 

               a)   Subject to the rights of holders of any class of capital
stock or series thereof expressly ranking senior to the Series A Preferred, upon
any voluntary or
                          
                                       3
<PAGE>
 
involuntary liquidation, dissolution or winding up of the affairs of the
Corporation, the holder of each share of the Series A Preferred then outstanding
shall be entitled to be paid out of the assets of the Corporation available for
distribution to its stockholders an amount equal to $10.00 for each share of
Series A Preferred then held by such holder plus an amount equal to all
accumulated but unpaid dividends thereon through the date of payment (whether or
not earned or declared and whether or not there are funds legally available for
the payment of dividends) (such amount being herein called the "Liquidation
                                                                -----------
Preference") before any payment shall be made or any assets distributed to the
- ----------
holders of Common Stock or any other series of capital stock junior to the
Series A Preferred. If the assets of the Corporation are not sufficient to pay
in full the payments payable to the holders of outstanding shares of Series A
Preferred and any Pari Passu Classes upon the liquidation, dissolution or
winding up of the affairs of the Corporation, then the holders of all such
shares shall share ratably with all other holders of shares of Series A
Preferred and Pari Passu Classes in such distribution of assets in proportion to
the Liquidation Preference of the respective shares.

          b)   For the purposes of this Section 3, neither the voluntary sale,
conveyance, exchange or transfer (for cash, shares of stock, securities or other
consideration) of all or substantially all the property or assets of the
Corporation nor the consolidation or merger of the Corporation with or into one
or more other corporations or other entities shall be deemed to be a
liquidation, dissolution or winding up of the Corporation, voluntarily or
involuntarily.

          4.   Conversion.
               ---------- 

               a)   Rights of Holder of Convert. At any time after 90 days
                    ---------------------------                           
following the date of the issuance of the Series A Preferred, each holder of
shares of Series A Preferred may, at the option of the holder exercisable at any
time and from time to time, convert some or all of each of such holder's shares
of Series A Preferred into: (i) ten shares of the Common Stock, par value $0.01
per share (the "Common Stock"), of the Corporation, and (ii) one two-year
                ------------                                             
warrant to purchase two shares of the Common Stock, par value $0.01 per share
(the "UTTC Common"), of Universal Trading Technologies Corporation, a Delaware
corporation ("UTTC"), with an exercise price of $0.75 per share (the "Warrants")
                                                                      --------  
(such number of securities, as adjusted from time to time pursuant hereto, is
herein called the "Conversion Ratio").

               b)   Adjustments to Conversion Ratio. The Conversion Ratio shall
                    -------------------------------                            
be adjusted, from time to time by the Board of Directors of the Corporation, to
reflect the effect of any stock dividend, stock split, reverse stock split,
merger, consolidation, recapitalization (other than the issuance of Common Stock
in exchange for indebtedness or other obligation of similar value),
reorganization or other similar transaction affecting the Corporation or UTTC so
that immediately following such event the holders of the Series A Preferred
shall be entitled to receive upon conversion thereof the kind and amount of
shares of securities of the Corporation and UTTC and other property which they
would have owned or been entitled to receive upon or by reason of such event if
such shares of Series A Preferred had been converted immediately before the
record date (or, if no record date, the effective date) for such event. An
adjustment 

                                       4
<PAGE>
 
made pursuant to this paragraph b) of this Section 4 shall become effective
immediately after the opening of business on the day next following the record
date in the case of a dividend or distribution and shall become effective
immediately after the opening of business on the day next following the
effective date in the case of a subdivision, combination, reclassification,
merger, recapitalization, reorganization or other similar transaction. In case
of (i) any consolidation or merger to which the Corporation or UTTC is a party,
other than a merger or consolidation in which the Corporation or UTTC, as the
case may be, is the surviving or continuing corporation and which does not
result in any reclassification of, or change (other than a change in par value
or from par value to no par value or from no par value to par value, or as a
result of a subdivision or combination) in, outstanding shares of Common Stock
(or such other class or series of common stock into which shares of Series A
Preferred are then convertible, including Warrants) or (ii) any sale or
conveyance of all or substantially all of the property and assets of the
Corporation or UTTC, then provision shall be made as part of the terms of such
transaction whereby the holder of each share of Series A Preferred which is not
converted into the right to receive stock or other securities and property in
connection with such transaction shall have the right thereafter to convert
such share of Series A Preferred into the kind and amount of shares of stock or
other securities and property receivable upon such consolidation, merger, sale
or conveyance by a holder of the number of shares of Common Stock and/or UTTC
Common issuable upon the exercise of the Warrants (or such other class or series
of common stock into which shares of Series A Preferred are then convertible)
into which such shares of Series A Preferred could have been converted
immediately prior to such consolidation, merger, sale or conveyance, subject to
adjustment which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this paragraph b) of this Section 4. The Corporation
shall not enter into any of the transactions referred to in clauses (i) or (ii)
of the first sentence of this paragraph unless, prior to the consummation
thereof, effective provision shall be made in a certificate or articles of
incorporation or other constituent document or written instrument of the
Corporation or the entity surviving the consolidation or merger, if other than
the Corporation, or the entity acquiring the Corporation's assets, unless, in
either case, such entity is a direct or indirect subsidiary of another entity,
in which case such provision shall be made in the certificate or articles of
incorporation or other constituent document or written instrument of such other
entity (any such entity or other entity being the "Surviving Entity") so as to
                                                   ----------------
assume the obligation to deliver to each holder of shares of Series A Preferred
such stock or other securities and property and otherwise give effect to the
provisions set forth in this paragraph. The provisions of this paragraph shall
apply similarly to successive consolidations, mergers, sales or conveyances.

          The Corporation shall give each holder of Series A Preferred prior
written notice delivered to the applicable address set forth on the record books
of the Corporation of each adjustment made pursuant to this paragraph b) of
Section 4.

          c)   Procedures for Conversion. Any holder of Series A Preferred
               -------------------------                                  
electing to convert such shares or any portion thereof shall deliver the
certificates therefor to the principal office of the Corporation, with the form
of notice of election to convert endorsed on such 

                                       5
<PAGE>
 
certificates fully completed and duly executed. The conversion right with
respect to such Series A Preferred shall be deemed to have been exercised on the
date upon which the certificates therefor with such notice of election duly
executed shall have been so delivered, and the person or persons entitled to
receive Common Stock and Warrants issuable upon such conversion shall be treated
for all purposes as the record holder or holders of such Common Stock and
Warrants on such date. Any declared but unpaid dividends payable through the
Conversion Date with respect to Series A Preferred so converted shall be payable
upon such conversion.

          d)   No Fractional Securities. No fractional shares of Common Stock
               ------------------------                                      
nor Warrants to purchase fractional shares of Common Stock shall be issued upon
conversion of shares of Series A Preferred. Instead of any fractional shares of
Common Stock or Warrants to purchase fractional shares of UTTC Common which
would otherwise be issuable upon conversion of any share or shares of Series A
Preferred, the Corporation shall pay a cash adjustment in respect of such
fraction in such amount as the Board of Directors of the Corporation shall in
good faith determine.

          e)   Taxes. If a holder converts shares of Series A Preferred, the
               -----                                                        
Corporation shall pay any documentary, stamp or similar issue or transfer tax
due on the issue of securities of the Corporation or UTTC to the holder upon the
conversion. The holder shall pay any such tax due because any shares are issued
in a name other than the holder's.

          f)   Reservation of Shares. The Corporation shall at all times reserve
               ---------------------                                            
out of its authorized but unissued shares of Common Stock, or such shares held
in treasury (and use reasonable efforts to cause UTTC to reserve out of its
authorized but unissued shares of UTTC Common, or such shares held in treasury)
enough of such shares (or other securities deliverable upon conversion) to
permit the conversion of all of the Series A Preferred then outstanding and the
issuance of shares of UTTC Common issuable upon the exercise of the Warrants
issuable upon the conversion of all of the Series A Preferred then outstanding.
All shares of Common Stock issued upon due conversion of shares of Series A
Preferred shall be validly issued, fully paid and non-assessable. All shares of
UTTC Common issuable upon (i) exercise of the Warrants issued upon due
conversion of the Series A Preferred, and (ii) receipt by UTTC of the applicable
exercise price therefor, shall be fully paid, and non-assessable.

          5.   Redemption.
               ---------- 

               a)   General. At any time and from time to time (i) after the
                    -------                                                 
second anniversary of the date of issuance of the Series A Preferred, or (ii)
after the date upon which the trading price for the Common Stock on the
principal exchange or automated quotation system upon which the Common Stock
then trades equals or exceeds $3.25 per share of Common Stock for a period of at
least 10 consecutive trading days, the Corporation may redeem all or any portion
of the then outstanding Series A Preferred for an amount in cash equal to the
Liquidation Preference in accordance with the provisions of this paragraph 5.

                                       6
<PAGE>
 
               b)   Redemption Procedure. If the Corporation shall determine to
                    --------------------                                       
redeem less than all shares of the Series A Preferred then outstanding pursuant
to subparagraph (a) of this paragraph 5, (i) the shares to be redeemed shall be
selected pro rata (or as nearly as may be) so that the number of shares redeemed
from each holder shall bear the same proportion to all the shares to be redeemed
that the total number of shares then held by such holder bears to the total
number of shares then outstanding or (ii) if the number of holders of the Series
A Preferred Stock exceeds 50, and the Board of Directors so determines, the
shares to be redeemed shall be selected by lot.

               c)   Notice. Notice of every redemption pursuant to this
                    ------                                             
paragraph 5 shall be mailed, first class, postage prepaid, not less than 30 nor
more than 60 days prior to the date fixed for redemption (the "Redemption
Date"), to each holder's address as it appears on the books of the Corporation.
Each such notice shall state: the Redemption Date; the number of shares of
Series A Preferred to be redeemed, and, if less than all shares of Series A
Preferred held by such holder are to be redeemed, the number of such shares to
be redeemed from such holder; the redemption price applicable to the shares to
be redeemed; the place or places where such shares are to be surrendered; and
that dividends on shares to be redeemed will cease to accrue on the Redemption
Date.

               d)   Rights of Holders. Notice having been mailed as aforesaid,
                    -----------------                                         
from and after the Redemption Date (unless the Corporation defaults in providing
money for the payment of the redemption price) dividends on shares called for
redemption shall cease to accrue, said shares shall no longer be deemed to be
outstanding, all rights of holders thereof as stockholders of the Corporation
(except the right to receive the redemption price thereof, without interest)
shall terminate, and, upon surrender, in accordance with said notice, of the
certificates representing any such shares (properly endorsed or assigned for
transfer, if the Board of Directors of the Corporation shall so require), such
shares shall be redeemed by the Corporation at the applicable redemption price;
provided, however, that the Corporation may include in such notice a statement
- -----------------                                                             
that the money required for the payment of the redemption price will be
deposited on a specified date, prior to the Redemption Date, with a specified
bank or trust company (which shall have an office in The City of New York and
which shall have a combined capital and surplus of not less than $50,000,000) in
trust for the benefit of holders of shares called for redemption, and, notice
having been given, from and after such deposit shares called for redemption
shall no longer be deemed to be outstanding and all rights with respect to such
shares shall forthwith upon such deposit cease and terminate except for the
right to receive the amount payable upon surrender of the certificates
representing such shares from such bank or trust company (but not from the
Corporation). If less than all the shares represented by any surrendered
certificate are redeemed, a new certificate representing the unredeemed shares
shall be issued to the holder who surrendered such certificate. Holders of
shares of Series A Preferred called for redemption shall not be entitled to any
interest allowed by any such depositary on money deposited to effect the
redemption but any such interest shall be paid to the Corporation. Any money
deposited as aforesaid for redemption of any shares and remaining unclaimed for
four years and eleven months after the date of such deposit shall then be repaid
to the 

                                       7
<PAGE>
 
Corporation upon its request, and the holders of such shares shall thereafter
look only to the Corporation for payment of the redemption price thereof,
without interest.

          e)   Status of Redeemed Shares. Any share of Series A Preferred
               -------------------------                                 
redeemed or otherwise purchased or acquired by the Corporation shall be retired,
shall no longer be deemed outstanding, and shall not be reissued.

          6.   Voting Rights.
               ------------- 

               a)   Generally. The holders of record of shares of Series A
                    ---------                                             
Preferred shall not be entitled to vote on any matters presented to the
stockholders of the Company for approval, except as required by law.

          7.   General Provisions.
               ------------------ 

               a)   "Outstanding" Securities. The term "outstanding", when used
                     -----------------------            -----------            
with reference to shares of stock, shall mean issued shares, excluding shares
held by the Corporation, or a subsidiary thereof.

               b)   Headings. The headings of the paragraphs, subparagraphs,
                    ----------                                              
clauses, and sub-clauses of this Certificate of Designations are for convenience
of reference only and shall not define, limit, or affect any of the provisions
hereof.

          The Ashton Technology Group, Inc. (the "Corporation"), a corporation
                                                  -----------                 
organized and existing under the General Corporation Law of the State of
Delaware (the "DGCL"), does hereby certify that pursuant to the provisions of
Section 151 of the DGCL, the Board of Directors of the Corporation, at a meeting
duly convened on September 11, 1997 at which a quorum was present at all times,
adopted the following resolution, which resolution remains in full force and

          WHEREAS, the Board of Directors of the Corporation is authorized,

of Incorporation, to fix by resolution or resolutions the designation of each

or other special rights of any such class or series of Preferred Stock, as well
as such other provisions with regard to redemption (at the option of the holders
thereof and/or at the option of the Corporation), dividends, dissolution or the
distribution of assets, conversion or exchange, and any qualifications or
restrictions thereof or such other subjects or matters as shall be stated and
expressed in the resolution or resolutions providing for the issue of such stock
adopted by the Board of Directors; and

          WHEREAS, it is the desire of the Board of Directors of the
Corporation, pursuant to such authority, to authorize and fix the terms of the
series of Preferred Stock designated as Series B Convertible Preferred Stock
(the "Series B Preferred"):
      ------------------   

                                       2
<PAGE>
 
          NOW THEREFORE, be it resolved, that the terms and provisions of such
series and all other rights or preferences granted to or imposed upon such
series or the holders thereof are as herein set forth:

          1.   Rank. The Series B Preferred shall, with respect to dividend
               ----                                                        
rights or rights upon liquidation, dissolution and winding-up of the
Corporation, rank pari passu with all other series of preferred stock or other
class of security expressly ranking pari passu ("Pari Passu Classes") with the
                                                 ---- -------------           
Series A Preferred of the Corporation (including, without limitation, the Series
A Convertible PIK Preferred of the Corporation) and prior to all series or
classes of Common Stock of the Corporation ("Common Stock"). Nothing contained
                                             ------------                     
herein shall be construed to prohibit the Corporation from authorizing or
issuing, in accordance with its Certificate of Incorporation and By-Laws, as the
same may be amended and in effect from time to time, any classes or series of
equity securities of the Corporation ranking senior to or pari passu with the
Series B Preferred with respect to dividend rights or rights upon liquidation,
dissolution and winding-up of the Corporation or both.

          2.   Dividends. The holders of the shares of the Series B Preferred
               ---------                                                     
shall be entitled to be paid, when, as and if declared by the Board of Directors
of the Corporation out of funds legally available for the payment of dividends,
dividends at the rate of 9% per annum payable semiannually on February 15 and
August 15 of each year, commencing February 15, 1998 (a "Dividend Payment
Date"). Such dividends shall, if declared, be paid to the holders of record of
the Series B Preferred at the close of the business day on February 15 and
August 15 of each year commencing February 15, 1998. Each of such semi-annual
dividends shall be fully cumulative and shall accrue (whether or not declared),
without interest, from the date of the immediately preceding Dividend Payment
Date, except with respect to the first dividend payment which will accrue from
the date of issuance of the Series B Preferred.

          3.   Liquidation Preference.
               ---------------------- 

               a)   Subject to the rights of holders of any class of capital
stock or series thereof expressly ranking senior to the Series B Preferred, upon
any voluntary or involuntary liquidation, dissolution or winding up of the
affairs of the Corporation, the holder of each share of the Series B Preferred
then outstanding shall be entitled to be paid out of the assets of the
Corporation available for distribution to its stockholders an amount equal to
$10.00 for each share of Series B Preferred then held by such holder plus an
amount equal to all accumulated but unpaid dividends thereon through the date of
payment (whether or not earned or declared and whether or not there are funds
legally available for the payment of dividends) (such amount being herein called
the "Liquidation Preference") before any payment shall be made or any assets
     ----------------------                                                 
distributed to the holders of Common Stock or any other series of capital stock
junior to the Series B Preferred. If the assets of the Corporation are not
sufficient to pay in full the payments payable to the holders of outstanding
shares of Series B Preferred and any Pari Passu Classes upon the liquidation,
dissolution or winding up of the affairs of the Corporation, then the holders of
all such shares shall share ratably with all other holders of shares of Series B
Preferred

                                       3
<PAGE>
 
and Pari Passu Classes in such distribution of assets in proportion to the
Liquidation Preference of the respective shares.

               b)   For the purposes of this Section 3, neither the voluntary
sale, conveyance, exchange or transfer (for cash, shares of stock, securities or
other consideration) of all or substantially all the property or assets of the
Corporation nor the consolidation or merger of the Corporation with or into one
or more other corporations or other entities shall be deemed to be a
liquidation, dissolution or winding up of the Corporation, voluntarily or
involuntarily.

          4.   Conversion.
               ---------- 

               a)   Rights of Holder of Convert.  At any time after 90 days
                    ---------------------------                            
following the date of the issuance of the Series B Preferred, each holder of
shares of Series B Preferred may, at the option of the holder exercisable at any
time and from time to time, convert some or all of each of such holder's shares
of Series B Preferred into: (i) six shares of the Common Stock, par value $0.01
per share (the "Common Stock"), of the Corporation, and (ii) one two-year
                ------------                                             
warrant to purchase two shares of the Common Stock, par value $0.01 per share
(the "UTTC Common"), of Universal Trading Technologies Corporation, a Delaware
      -----------                                                             
corporation ("UTTC"), with an exercise price of $0.75 per share (the "Warrants")
              ----                                                    --------  
(such number of securities, as adjusted from time to time pursuant hereto, is
herein called the "Conversion Ratio").
                   ----------------   

               b)   Adjustments to Conversion Ratio.  The Conversion Ratio shall
                    -------------------------------                             
be adjusted, from time to time by the Board of Directors of the Corporation, to
reflect the effect of any stock dividend, stock split, reverse stock split,
merger, consolidation, recapitalization (other than the issuance of Common Stock
in exchange for indebtedness or other obligation of similar value),
reorganization or other similar transaction affecting the Corporation or UTTC so
that immediately following such event the holders of the Series B Preferred
shall be entitled to receive upon conversion thereof the kind and amount of
shares of securities of the Corporation and UTTC and other property which they
would have owned or been entitled to receive upon or by reason of such event if
such shares of Series B Preferred had been converted immediately before the
record date (or, if no record date, the effective date) for such event. An
adjustment made pursuant to this paragraph b) of this Section 4 shall become
effective immediately after the opening of business on the day next following
the record date in the case of a dividend or distribution and shall become
effective immediately after the opening of business on the day next following
the effective date in the case of an applicable subdivision, combination,
reclassification, merger, recapitalization, reorganization or other similar
transaction. In case of (i) any consolidation or merger to which the Corporation
or UTTC is a party, other than a merger or consolidation in which the
Corporation or UTTC, as the case may be, is the surviving or continuing
corporation and which does not result in any reclassification of, or change
(other than a change in par value or from par value to no par value or from no
par value to par value, or as a result of a subdivision or combination) in,
outstanding shares of Common Stock (or such other class or series of common
stock into which shares of Series B Preferred are then convertible, including
Warrants) or (ii) any sale or conveyance of all or substantially all of the
property and

                                       4
<PAGE>
 
assets of the Corporation or UTTC, then provision shall be made as part of the
terms of such transaction whereby the holder of each share of Series B Preferred
which is not converted into the right to receive stock or other securities and
property in connection with such transaction shall have the right thereafter to
convert such share of Series B Preferred into the kind and amount of shares of
stock or other securities and property receivable upon such consolidation,
merger, sale or conveyance by a holder of the number of shares of Common Stock
and/or shares of UTTC Common issuable upon the exercise of the Warrants (or such
other class or series of common stock into which shares of Series B Preferred
are then convertible) into which such shares of Series B Preferred could have
been converted immediately prior to such consolidation, merger, sale or
conveyance, subject to adjustment which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this paragraph b) of this Section
4. The Corporation shall not enter into any of the transactions referred to in
clauses (i) or (ii) of the first sentence of this paragraph unless, prior to the
consummation thereof, effective provision shall be made in a certificate or
articles of incorporation or other constituent document or written instrument of
the Corporation or the entity surviving the consolidation or merger, if other
than the Corporation, or the entity acquiring the Corporation's assets, unless,
in either case, such entity is a direct or indirect subsidiary of another
entity, in which case such provision shall be made in the certificate or
articles of incorporation or other constituent document or written instrument of
such other entity (any such entity or other entity being the "Surviving Entity")
                                                              ----------------
so as to assume the obligation to deliver to each holder of shares of Series B
Preferred such stock or other securities and property and otherwise give effect
to the provisions set forth in this paragraph. The provisions of this paragraph
shall apply similarly to successive consolidations, mergers, sales or
conveyances.

          The Corporation shall give each holder of Series B Preferred prior
written notice delivered to the applicable address set forth on the record books
of the Corporation of each adjustment made pursuant to this paragraph b) of
Section 4.

          c)   Procedures for Conversion.  Any holder of Series B Preferred
               -------------------------                                   
electing to convert such shares or any portion thereof shall deliver the
certificates therefor to the principal office of the Corporation, with the form
of notice of election to convert endorsed on such certificates fully completed
and duly executed. The conversion right with respect to such Series B Preferred
shall be deemed to have been exercised on the date upon which the certificates
therefor with such notice of election duly executed shall have been so
delivered, and the person or persons entitled to receive Common Stock and
Warrants issuable upon such conversion shall be treated for all purposes as the
record holder or holders of such Common Stock and Warrants on such date. Any
declared but unpaid dividends payable through the Conversion Date with respect
to Series B Preferred so converted shall be payable upon such conversion.

          d)   No Fractional Securities. No fractional shares of Common Stock
               ------------------------                                      
nor Warrants to purchase fractional shares of UTTC Common shall be issued upon
conversion of shares of Series B Preferred. Instead of any fractional shares of
Common Stock or Warrants to purchase fractional shares of UTTC Common which
would otherwise be issuable upon

                                       5
<PAGE>
 
conversion of any share or shares of Series B Preferred, the Corporation shall
pay a cash adjustment in respect of such fraction in such amount as the Board of
Directors of the Corporation shall in good faith determine.

          e)   Taxes. If a holder converts shares of Series B Preferred, the
               -----                                                        
Corporation shall pay any documentary, stamp or similar issue or transfer tax
due on the issue of securities of the Corporation or UTTC to the holder upon the
conversion. The holder shall pay any such tax due because any shares are issued
in a name other than the holder's.

          f)   Reservation of Shares.  The Corporation shall at all times
               ---------------------                                     
reserve out of its authorized but unissued shares of Common Stock, or such
shares held in treasury (and use reasonable efforts to cause UTTC to reserve out
of its authorized but unissued shares of UTTC Common, or such shares held in
treasury), enough of such shares (or other securities deliverable upon
conversion) to permit the conversion of all of the Series B Preferred then
outstanding and the issuance of shares of Common Stock and the issuance of UTTC
Common issuable upon the exercise of the Warrants, in each case issuable upon
the conversion of all of the Series B Preferred then outstanding. All shares of
Common Stock issued upon due conversion of shares of Series B Preferred shall be
validly issued, fully paid and non-assessable. All shares of Common Stock
issuable upon (i) exercise of the Warrants issued upon due conversion of the
Series B Preferred, and (ii) receipt by UTTC of the applicable exercise price
therefor, shall be fully paid, and non-assessable.

          5.   Redemption.
               ---------- 

               a)   General.  At any time and from time to time (i) after the
                    -------                                                  
second anniversary of the date of issuance of the Series B Preferred, or (ii)
after the date upon which the trading price for the Parent Common Stock on the
principal exchange or automated quotation system upon which the Parent Common
Stock then trades equals or exceeds $3.25 per share of Parent Common Stock for a
period of at least 10 consecutive trading days, the Corporation may redeem all
or any portion of the then outstanding Series B Preferred for an amount in cash
equal to the Liquidation Preference in accordance with the provisions of this
paragraph 5.

               b)   Redemption Procedure.  If the Corporation shall determine to
                    --------------------                                        
redeem less than all shares of the Series B Preferred then outstanding pursuant
to subparagraph (a) of this paragraph 5, (i) the shares to be redeemed shall be
selected pro rata (or as nearly as may be) so that the number of shares redeemed
from each holder shall bear the same proportion to all the shares to be redeemed
that the total number of shares then held by such holder bears to the total
number of shares then outstanding or (ii) if the number of holders of the Series
B Preferred Stock exceeds 50, and the Board of Directors so determines, the
shares to be redeemed shall be selected by lot.

               c)   Notice.  Notice of every redemption pursuant to this
                    ------                                              
paragraph 5 shall be mailed, first class, postage prepaid, not less than 30 nor
more than 60 days prior to the

                                       6
<PAGE>
 
date fixed for redemption (the "Redemption Date"), to each holder's address as
it appears on the books of the Corporation. Each such notice shall state: the
Redemption Date; the number of shares of Series B Preferred to be redeemed, and,
if less than all shares of Series B Preferred held by such holder are to be
redeemed, the number of such shares to be redeemed from such holder; the
redemption price applicable to the shares to be redeemed; the place or places
where such shares are to be surrendered; and that dividends on shares to be
redeemed will cease to accrue on the Redemption Date.

               d)   Rights of Holders.  Notice having been mailed as aforesaid,
                    -----------------                                          
from and after the Redemption Date (unless the Corporation defaults in providing
money for the payment of the redemption price) dividends on shares called for
redemption shall cease to accrue, said shares shall no longer be deemed to be
outstanding, all rights of holders thereof as stockholders of the Corporation
(except the right to receive the redemption price thereof, without interest)
shall terminate, and, upon surrender, in accordance with said notice, of the
certificates representing any such shares (properly endorsed or assigned for
transfer, if the Board of Directors of the Corporation shall so require), such
shares shall be redeemed by the Corporation at the applicable redemption price;
provided, however, that the Corporation may include in such notice a statement
that the money required for the payment of the redemption price will be
deposited on a specified date, prior to the Redemption Date, with a specified
bank or trust company (which shall have an office in The City of New York and
which shall have a combined capital and surplus of not less than $50,000,000) in
trust for the benefit of holders of shares called for redemption, and, notice
having been given, from and after such deposit shares called for redemption
shall no longer be deemed to be outstanding and all rights with respect to such
shares shall forthwith upon such deposit cease and terminate except for the
right to receive the amount payable upon surrender of the certificates
representing such shares from such bank or trust company (but not from the
Corporation). If less than all the shares represented by any surrendered
certificate are redeemed, a new certificate representing the unredeemed shares
shall be issued to the holder who surrendered such certificate. Holders of
shares of Series B Preferred called for redemption shall not be entitled to any
interest allowed by any such depositary on money deposited to effect the
redemption but any such interest shall be paid to the Corporation. Any money
deposited as aforesaid for redemption of any shares and remaining unclaimed for
four years and eleven months after the date of such deposit shall then be repaid
to the Corporation upon its request, and the holders of such shares shall
thereafter look only to the Corporation for payment of the redemption price
thereof, without interest.

               e)   Status of Redeemed Shares. Any share of Series B Preferred
                    -------------------------                                 
redeemed or otherwise purchased or acquired by the Corporation shall be retired,
shall no longer be deemed outstanding, and shall not be reissued.

          6.   Voting Rights. The holders of record of shares of Series B
               -------------                                             
Preferred shall not be entitled to vote on any matters presented to the
stockholders of the Company for approval, except as required by law.

          7.   General Provisions.
               ------------------ 

               a)   "Outstanding" Securities. The term "outstanding", when used
                     -----------------------            -----------            
with reference to shares of stock, shall mean issued shares, excluding shares

9% SUBORDINATED NON-CONVERTIBLE PROMISSORY NOTE DUE 
JANUARY 31, 1999

$___________ U.S.                                    April 18, 1997

          UNIVERSAL TRADING TECHNOLOGIES CORPORATION, a Delaware corporation
(the "Company"), for value received, promises to pay to the order of
_______________ ________________________ at _________________________________ or
at the offices of the Company, the sum of $_________ U.S. on JANUARY 31, 1999
with interest from the date hereof on the unpaid principal hereof until maturity
(whether as stated or by acceleration), according to the tenor hereof, at a rate
of 9% per annum (and after such maturity or demand at a rate per annum equal to
9%) until such principal is paid in full. Interest shall be payable annually in
arrears on JANUARY 31, 1998 and on JANUARY 31, 1999 or upon the earlier of the
prepayment or due date of the note. Interest shall be calculated on the basis
of a 360-day year for actual days elapsed. This note is one of a series of 9%
subordinated non-convertible promissory notes that have been delivered to
investors in a Private Placement by the Company, all of which notes are
hereinafter referred to as the "Notes". The Notes are direct, unsecured
obligations of the Company.

          The Company for itself, its successors and assigns, covenants and
agrees, and each holder of the Notes, by his acceptance hereof, likewise
covenants and agrees, that the payment of the principal of, premium (if any) and
interest on, the Notes is hereby expressly subordinated, to the extent and in
the manner hereinafter set forth, in right of payment to the prior payment in
full of all "Senior Indebtedness," as that term is herein defined.

          In case of any distribution of assets of the Company upon any
dissolution, winding up, liquidation or reorganization of the Company, whether
in bankruptcy, insolvency, reorganization or receivership proceedings or upon an
assignment for the benefit of creditors or any other marshalling of the assets
and liabilities of the Company:

          (a) the holders of all Senior Indebtedness shall first be entitled to
receive payment thereof in full, including all principal, premium, if any, and
interest, or provision shall be made for such payment before the holders of the
Notes receive any payment upon the principal of, premium, if any, or interest
on, indebtedness evidenced by the Notes;

                                      -1-
<PAGE>
 
          (b)  any payment or distribution of assets of the Company of any kind
or character, whether in cash, property or securities, to which the holders of
the Notes would be entitled except for the subordination provisions hereof shall
be paid and/or delivered by the liquidating trustee or agent or other person
making such payment or distribution, whether a trustee in bankruptcy, a receiver
or liquidating trustee or otherwise, directly to the holders of Senior
Indebtedness or their representative or representatives or to the trustee or
trustees under any indenture under which any instruments evidencing any of such
Senior Indebtedness may have been issued, as their respective interests may
appear, for application to the payment of amounts remaining unpaid on account of
the Senior Indebtedness held or represented by each to the extent necessary to
make payment in full of all Senior Indebtedness remaining unpaid, after giving
effect to any concurrent payment or distribution (or provision therefor) to the
holders of such Senior Indebtedness; and

          (c)  in the event that notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, shall be received by the holders of the Notes before all
Senior Indebtedness is paid in full or provision is made for such payment, such
payment or distribution shall be held in trust for the benefit of and promptly
paid over to the holders of such Senior Indebtedness or their representative or
representatives or to the trustee or trustees under any indenture under which
any instruments evidencing any of such Senior Indebtedness may have been issued,
as their respective interests may appear, for application to the payment of all
Senior Indebtedness remaining unpaid until all such Senior Indebtedness shall
have been paid in full, after giving effect to any concurrent payment or
distribution (or provision therefor) to the holders of such Senior Indebtedness.

          Upon the payment in full of all Senior Indebtedness, the holders  of
the Notes shall be subrogated to the rights of the holders of Senior
Indebtedness to receive payments or distributions of assets of the Company
applicable to the Senior Indebtedness until the unpaid principal of, premium, if
any, and interest on the Notes shall be paid in full. No such payments or
distributions applicable to the Senior Indebtedness shall, as between the
Company, its creditors other than the holders of Senior Indebtedness, and the
holders of the Notes, be deemed to be a payment by the Company to or on account
of the Notes. The subordination provisions of the Notes are intended solely for
the purpose of defining the relative rights of the holders of the Notes, on the
one hand, and the holders of the Senior Indebtedness, on the other hand.

          Nothing contained herein is intended to or shall impair, as between
the Company, its creditors other than the holders of Senior Indebtedness, and
the holders of the Notes, the obligation of the Company, which is unconditional
and absolute, to pay to the holders of the Notes the principal of (and premium,
if any) and interest on the Notes as and when the same shall become due and
payable in accordance with its terms, or to affect the relative rights of the
holders of the Notes and creditors of the Company other than the holders of the
Senior Indebtedness, nor shall anything herein or therein prevent the holders of
the Notes from exercising all remedies otherwise permitted by applicable law
upon default under the Notes, subject to the rights, if any, under the
subordination provisions of the Notes of the holders of Senior Indebtedness in
respect of cash, property or securities of the Company received upon the
exercise of any such remedy.

          Upon any payment or distribution of assets of the Company referred to
in the subordination provisions of the Notes, the holders of the Notes shall be
entitled to rely upon any order or decree made by any court of competent
jurisdiction in which such dissolution, winding up, liquidation or
reorganization proceedings are pending or upon a certificate of the liquidating
trustee or agent or other person making any distribution to the holders of the
Notes for the purpose of ascertaining the persons entitled to participate in
such distribution, the holders of the Senior Indebtedness and other indebtedness
of the Company, the amount thereof or payable thereon, the amount or amounts
paid or distributed thereon and all other facts pertinent thereto or to the
subordination provisions of the Notes.

          No payments on account of principal, premium, if any, or interest on
the Notes, shall be made unless full payment of amounts then due for principal,
premium, if any, sinking funds and interest on Senior Indebtedness has been made
or duly provided for in money or money's worth.  No payments on account of
principal, premium, if any, or interest on the Notes, shall be made if:  (i) at
the time of such payment or immediately after giving effect thereto, there shall
exist under any Senior Indebtedness or any agreement pursuant to which any
Senior Indebtedness is issued, any default or any condition, event or act, which
with notice or lapse of time, or both, would constitute a default, or (ii) the
Company shall have received from any holder of Senior Indebtedness or the
representative of a holder of Senior Indebtedness written notice of the
existence of any default or any condition, event or act, which, with notice or
lapse of time, or both, would constitute a default, or which would preclude the
making of any payment by the Company with respect to the principal, premium, if
any, or interest on the Notes; in any such case unless and until such default
shall have been cured or waived or shall have ceased to exist.

          Nothing contained in the subordination provisions of the Notes, shall
affect the obligation of the Company to make, or prevent the Company from
making, at any time except during the pendency of any such insolvency,
bankruptcy, dissolution, winding up, liquidation or reorganization proceedings,
and except during the continuance of any default specified in the immediately
preceding paragraph (not cured or waived), payments at any time of principal of,
and premium or interest on, the Notes.

          The term "Senior Indebtedness" shall mean the principal of, and
premium (if any) on, and interest on all indebtedness of the Company (other than
the Notes), whether outstanding on the date of the Notes or hereafter created
for money borrowed by the Company or other monetary obligations of the Company
(whether the same be evidenced by debentures or notes (other than the Notes) or
evidenced by a letter of credit, loan agreement or an indenture or similar
instrument) from, owing to, or guaranteed to, banks, trust companies, leasing
companies, insurance companies or other institutional lenders and any renewal,
extension refunding, amendment or modifications of any such Senior Indebtedness,
including without limitation of the foregoing, purchase money mortgages,
mortgages made or given or guaranteed by the Company as mortgagor or guarantor,
and assumed or guaranteed mortgages, upon property, but excluding any
indebtedness to trade creditors 

                                      -3-
<PAGE>
 
or suppliers on open account for work, labor, services and materials and
excluding any indebtedness which by the terms of the instrument creating or
evidencing the same is stated to be not superior in right of payment to the
Notes. During the continuation of any default in the payment of principal or
interest on any Senior Indebtedness, no payment of principal or interest may be
made by the Company on the Notes. The Notes contain no limitation on the amount
of additional Senior Indebtedness or other indebtedness that may be issued or
incurred. However, the Company will not in the future until the Notes have been
repaid in full incur indebtedness that is senior to the Notes other than Senior
Indebtedness; provided, however, that nothing shall prohibit the Company from
incurring secured indebtedness.

          The transferability of the Notes is restricted under the Federal and
state securities laws.

          NO SALE, OFFER TO SELL OR TRANSFER OF THE NOTES SHALL BE MADE UNLESS A
REGISTRATION STATEMENT UNDER THE FEDERAL SECURITIES ACT OF 1933, AS AMENDED,
WITH RESPECT TO SUCH SECURITIES IS THEN IN EFFECT OR AN EXEMPTION FROM THE
REGISTRATION REQUIREMENT OF SUCH ACT IS THEN IN FACT APPLICABLE TO SUCH
TRANSFER.
THE NOTES ARE NOT CONVERTIBLE INTO OTHER SECURITIES OF THE COMPANY.

                                   REDEMPTION

          1.1  Subject to the subordination provisions of the Notes, the Company
may, at its option, redeem the Notes in whole and not in part, at 100% of the
face value of the Notes plus accrued and unpaid interest to such date by giving
written notice to the holders of the Notes to that effect at least 30 calendar
days prior to the redemption date.

          Notice of redemption to the holders of the Notes shall be mailed by
the Company by first class mail, postage prepaid, at least 30 and not more than
60 days prior to the redemption date, to the holders of Notes, at their last
addresses as they shall appear in the books of Registration, but failure of a
Note holder to receive such notice shall not affect the validity of the
proceedings for the redemption of any of the Notes.

          1.2  Upon the giving of notice of redemption as above provided, the
Notes shall become due and payable on the date and at the place stated in such
notice at the applicable redemption price, together with interest accrued to the
date fixed for redemption, and on and after such date fixed for redemption
(unless the Company shall make default in the payment of such Notes at the
redemption), interest on the Notes so called for redemption shall cease to
accrue and such Notes shall be deemed not to be outstanding.

          1.3  Upon the completion by the Company of a private placement or
public offering wherein the Company receives gross proceeds of at least
$10,000,000 U.S. in any one transaction, the Company will promptly notify its
noteholders that it will redeem the Notes at 100% of the face amount of the
Notes plus accrued and unpaid interest.  Such notice will provide for the
redemption of the Notes six months after the completion of such offering.

          3.2. The holders of not less than 50% by amount of the Notes may
consent to change any terms covering the Notes except those terms relating to
interest rate, payment dates and maturity date which may be changed only by
unanimous consent of the Note holders.

          The holders of not less than fifty (50%) percent of the principal
amount of the Notes by notice in writing sent by registered mail to the Company
may declare the principal amount of all the Notes to be forthwith due and
payable, and upon any such declaration the same shall become immediately due and
payable, in the following events:

          (a)  If default shall be made in the payment of any installment of
interest on any of the Notes when and as the same shall become due and payable,
as herein provided, after allowance for a grace period of fifteen (15) days and
such default shall continue for a period of an additional fifteen (15) days
after written notice is received by the Company from the Note holders; or

          (b)  If default shall be made in the payment of the principal of any
of the Notes when and as the same shall become due and payable; or

          (c)  If the Company shall institute proceedings for voluntary
bankruptcy, or shall apply for or consent to the appointment of a receiver for
itself or any of its property, or shall make an assignment for the benefit of
its creditors, or shall go into voluntary liquidation or be dissolved, or shall
admit in writing its inability to pay its debts generally as they mature, or
shall institute proceedings for reorganization, readjustment, arrangement,
composition or similar relief under any bankruptcy, insolvency or other
applicable law, or shall file an answer in any such proceedings against it
joining in seeking such relief or not objecting thereto; or

          (d)  If an order, judgment or decree shall have been made for the
appointment of a receiver of the Company or of a substantial part of its
property, or approving a petition seeking reorganization, readjustment,
arrangement, composition or similar relief for the Company under any bankruptcy,
insolvency or other applicable law, or adjudging the Company to be bankrupt or
insolvent, and such order, judgment or decree shall remain in force for sixty
(60) days without any stay thereof; or

          (e)  If one or more judgments, decrees or orders for the payment of
money in excess of $100,000 U.S. in the aggregate shall be rendered against the
Company and/or its subsidiaries, and such judgments, decrees, or orders shall
continue unsatisfied and in effect for a period of 30 consecutive days without
being vacated, discharged, satisfied or stayed or bonded pending appeal.

                                   ARTICLE IV

                                 MISCELLANEOUS

<PAGE>
 
          4.2  The Notes shall be governed by and construed in accordance with
laws of the State of New York.

          4.3  No recourse shall be had for the payment of the principal of, or
interest on, the Notes, or for any claim based hereon, or otherwise in respect
hereof, against any incorporator, or against any past, present or future
stockholder, officer or director, as such, of the Company or of any successor
corporation, whether by virtue of any constitution, statute or rule of law, or
by the enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance hereof and as part of the consideration for the issue
hereof, expressly waived and released.

          4.4  The Company is prohibited from declaring any cash dividends prior
to payment in full of the Notes.

          4.5  Notwithstanding anything contained herein to the contrary, the
Notes may not be disposed of except in compliance with all applicable federal
and state securities laws. In this respect, before selling or otherwise
disposing of any Notes, the holder of such Notes shall give five business days
prior written notice to the Company of his intention to do so. The notice by the
holder shall specify the Notes proposed to be sold or otherwise disposed of and
describe in reasonable detail the amount of the proposed sale or other
disposition and shall be accompanied by an opinion (in form and substance
reasonably satisfactory to the Company's counsel) of the holder's securities
counsel addressed to the Company as to whether the proposed sale or other
disposition may be effected without the filing of a Registration Statement under
the Securities Act of 1933, as amended (the "Act"), covering the Notes proposed
to be sold or otherwise disposed of. If in the opinion of such counsel, and of
counsel for the Company, no such registration action is necessary, the holder
may sell or otherwise of dispose of such Notes in the manner described by him in
the notice given to the Company. (Copies of any documents which the holder or
his counsel files with the Securities and Exchange Commission regarding the sale
or other disposition will immediately be provided by him or his counsel to the
Company.) If, in the opinion of counsel for the Company registration of such
Notes under the Act is necessary, no such sale or other disposition may be
effected.

          The holder of the Notes may not sell or otherwise transfer the Notes
without the transferee agreeing to be bound by the provisions of the
Subscription Agreement pursuant to which the holder of the Notes is bound.  A
copy of such Subscription Agreement may be obtained from the Company at its
principal executive offices.

9% SUBORDINATED CONVERTIBLE PROMISSORY NOTE DUE
JANUARY 31, 1999

$_________ U.S.                                      April 18, 1997

          UNIVERSAL TRADING TECHNOLOGIES CORPORATION, a Delaware corporation
(the "Company"), for value received, promises to pay to the order of
_______________________________  at ____________________________ or at the
offices of the Company, the sum of $___________ U.S. on JANUARY 31, 1999 with
interest from the date hereof on the unpaid principal hereof until maturity
(whether as stated or by acceleration), according to the tenor hereof, at a rate
of 9% per annum (and after such maturity or demand at a rate per annum equal to
9%) until such principal is paid in full. Interest shall be payable annually in
arrears on JANUARY 31, 1998 and on JANUARY 31, 1999 or upon the earlier due date
of the note. Interest shall be calculated on the basis of a 360-day year for
actual days elapsed. This note is one of a series of 9% subordinated convertible
promissory notes that have been delivered to investors in a Private Placement by
the Company, all of which notes are hereinafter referred to as the "Notes". The
Notes are direct, unsecured obligations of the Company.

          The Company for itself, its successors and assigns, covenants and
agrees, and each holder of the Notes, by his acceptance hereof, likewise
covenants and agrees, that the payment of the principal of, premium (if any) and
interest on, the Notes is hereby expressly subordinated, to the extent and in
the manner hereinafter set forth, in right of payment to the prior payment in
full of all "Senior Indebtedness," as that term is herein defined.

          In case of any distribution of assets of the Company upon any
dissolution, winding up, liquidation or reorganization of the Company, whether
in bankruptcy, insolvency, reorganization or receivership proceedings or upon an
assignment for the benefit of creditors or any other marshalling of the assets
and liabilities of the Company:

          (a) the holders of all Senior Indebtedness shall first be entitled to
receive payment thereof in full, including all principal, premium, if any, and
interest, or provision shall be made for such payment before the holders of the
Notes receive any payment upon the principal of, premium, if any, or interest
on, indebtedness evidenced by the Notes;

          (b) any payment or distribution of assets of the Company of any kind
or character, whether in cash, property or securities, to which the holders of
the Notes would be entitled except for the subordination provisions hereof shall
be paid and/or delivered by the 

<PAGE>
 
liquidating trustee or agent or other person making such payment or
distribution, whether a trustee in bankruptcy, a receiver or liquidating trustee
or otherwise, directly to the holders of Senior Indebtedness or their
representative or representatives or to the trustee or trustees under any
indenture under which any instruments evidencing any of such Senior Indebtedness
may have been issued, as their respective interests may appear, for application
to the payment of amounts remaining unpaid on account of the Senior Indebtedness
held or represented by each to the extent necessary to make payment in full of
all Senior Indebtedness remaining unpaid, after giving effect to any concurrent
payment or distribution (or provision therefor) to the holders of such Senior
Indebtedness; and

          (c) in the event that notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, shall be received by the holders of the Notes before all
Senior Indebtedness is paid in full or provision is made for such payment, such
payment or distribution shall be held in trust for the benefit of and promptly
paid over to the holders of such Senior Indebtedness or their representative or
representatives or to the trustee or trustees under any indenture under which
any instruments evidencing any of such Senior Indebtedness may have been issued,
as their respective interests may appear, for application to the payment of all
Senior Indebtedness remaining unpaid until all such Senior Indebtedness shall
have been paid in full, after giving effect to any concurrent payment or
distribution (or provision therefor) to the holders of such Senior Indebtedness.

          Upon the payment in full of all Senior Indebtedness, the holders of
the Notes shall be subrogated to the rights of the holders of Senior
Indebtedness to receive payments or distributions of assets of the Company
applicable to the Senior Indebtedness until the unpaid principal of, premium, if
any, and interest on the Notes shall be paid in full. No such payments or
distributions applicable to the Senior Indebtedness shall, as between the
Company, its creditors other than the holders of Senior Indebtedness, and the
holders of the Notes, be deemed to be a payment by the Company to or on account
of the Notes. The subordination provisions of the Notes are intended solely for
the purpose of defining the relative rights of the holder of the Notes, on the
one hand, and the holder of the Senior Indebtedness, on the other hand.

          Nothing contained herein is intended to or shall impair, as between
the Company, its creditors other than the holders of Senior Indebtedness, and
the holder of the Notes, the obligation of the Company, which is unconditional
and absolute, to pay to the holder of the Notes the principal of (and premium,
if any) and interest on the Notes as and when the same shall become due and
payable in accordance with its terms, or to affect the relative rights of the
holders of the Notes and creditors of the Company other than the holders of the
Senior Indebtedness, nor shall anything herein or therein prevent the holders of
the Notes from exercising all remedies otherwise permitted by applicable law
upon default under the Notes, subject to the rights, if any, under the
subordination provisions of the Notes of the holders of Senior Indebtedness in
respect of cash, property or securities of the Company received upon the
exercise of any such remedy.

          Upon any payment or distribution of assets of the Company referred to
in the subordination provisions of the Notes, the holders of the Notes shall be
entitled to rely upon any order or decree made by any court of competent
jurisdiction in which such dissolution, winding up, liquidation or
reorganization proceedings are pending or upon a certificate of the liquidating
trustee or agent or other person making any distribution to the holders of the
Notes for the purpose of ascertaining the persons entitled to participate in
such distribution, the holders of the Senior Indebtedness and other indebtedness
of the Company, the amount thereof or payable thereon, the amount or amounts
paid or distributed thereon and all other facts pertinent thereto or to the
subordination provisions of the Notes.

          No payments on account of principal, premium, if any, or interest on
the Notes, shall be made unless full payment of amounts then due for principal,
premium, if any, sinking funds and interest on Senior Indebtedness has been made
or duly provided for in money or money's worth.  No payments on account of
principal, premium, if any, or interest on the Notes, shall be made if:  (i) at
the time of such payment or immediately after giving effect thereto, there shall
exist under any Senior Indebtedness or any agreement pursuant to which any
Senior Indebtedness is issued, any default or any condition, event or act, which
with notice or lapse of time, or both, would constitute a default, or (ii) the
Company shall have received from any holder of Senior Indebtedness or the
representative of a holder of Senior Indebtedness written notice of the
existence of any default or any condition, event or act, which, with notice or
lapse of time, or both, would constitute a default, or which would preclude the
making of any payment by the Company with respect to the principal, premium, if
any, or interest on the Notes; in any such case unless and until such default
shall have been cured or waived or shall have ceased to exist.

          Nothing contained in the subordination provisions of the Notes, shall
affect the obligation of the Company to make, or prevent the Company from
making, at any time except during the pendency of any such insolvency,
bankruptcy, dissolution, winding up, liquidation or reorganization proceedings,
and except during the continuance of any default specified in the immediately
preceding paragraph (not cured or waived), payments at any time of principal of,
and premium or interest on, the Notes.

          The term "Senior Indebtedness" shall mean the principal of, and
premium (if any) on, and interest on all indebtedness of the Company (other than
the Notes), whether outstanding on the date of the Notes or hereafter created
for money borrowed by the Company or other monetary obligations of the Company
(whether the same be evidenced by debentures or notes (other than the Notes) or
evidenced by a letter of credit, loan agreement or an indenture or similar
instrument) from, owing to, or guaranteed to, banks, trust companies, leasing
companies, insurance companies or other institutional lenders and any renewal,
extension refunding, amendment or modifications of any such Senior Indebtedness,
including without limitation of the foregoing, purchase money mortgages,
mortgages made or given or guaranteed by the Company as mortgagor or guarantor,
and assumed or guaranteed mortgages, upon property, but excluding any
indebtedness to trade creditors or suppliers on open account for work, labor,
services and materials and excluding any indebtedness which by the terms of the
instrument creating or evidencing the same is stated to be not superior in right
of payment to the Notes.  During the continuation of any default in the payment
of principal 

                                      -3-
<PAGE>
 
or interest on any Senior Indebtedness, no payment of principal or interest may
be made by the Company on the Notes. The Notes contain no limitation on the
amount of additional Senior Indebtedness or other indebtedness that may be
issued or incurred. However, the Company will not in the future until the Notes
have been repaid in full incur indebtedness that is senior to the Notes other
than Senior Indebtedness; provided, however, that nothing shall prohibit the
Company from incurring secured indebtedness.

          The transferability of the Notes is restricted under federal and state
securities laws.

          NO SALE, OFFER TO SELL OR TRANSFER OF THE NOTES SHALL BE MADE UNLESS A
REGISTRATION STATEMENT UNDER THE FEDERAL SECURITIES ACT OF 1933, AS AMENDED,
WITH RESPECT TO SUCH SECURITIES IS THEN IN EFFECT OR AN EXEMPTION FROM THE
REGISTRATION REQUIREMENT OF SUCH ACT IS THEN IN FACT APPLICABLE TO SUCH
TRANSFER.

THE NOTES ARE CONVERTIBLE INTO OTHER SECURITIES OF THE COMPANY.

                              CONVERSION OF NOTES

          1.1   Commencing eighteen months from April 18, 1997, the principal of
the Notes is convertible at a price of $1.00 per share.   In the event that the
Notes become due and payable prior to October 18, 1998, as provided in 4.1 of
Article IV, then the Company will notify the holders of the Notes of their right
to convert the Notes at least thirty days prior to the due date of the Notes.
In the event that the Notes are converted, the holder shall be entitled to
receive accrued but unpaid interest through the conversion date of the Notes.

          For the purpose of this Article, the term "Common Stock" shall mean
the capital stock of the Company of the class authorized and designated as
Common Stock at the date hereof or as such stock may, by change or
reclassification, be constituted from time to time.

          1.2.  The Company shall not be required to issue fractions of shares
of Common Stock upon conversions of the Notes.  If more than one Note shall be
surrendered for conversion at one time by the same holder, the number of shares
of Common Stock which shall be issuable upon conversion thereof shall be
computed on the basis of the aggregate principal amount of the Notes so
surrendered.  If any fractional interest in a share of Common Stock would
otherwise be deliverable upon the conversion of any Note or Notes, the Company
shall make adjustment therefor by rounding to the nearest whole share.

          1.3   The issue of Common Stock certificates on conversions of Notes
shall be made without charge to the holder for such certificates or any tax in
respect of the issue thereof.  The Company shall not, however, be required to
pay any tax which may be payable in respect of any transfer involved in the
issue and delivery of any certificate in any name other than that of the holder
of the Notes being converted, and the Company shall not be required to issue or
deliver any such shares unless and until the person or persons requesting the
issue thereof shall have paid to the Company the amount of such tax or shall
have established to the satisfaction of the Company that such tax has been paid.

          The Company shall at all times reserve and keep available out of its
authorized but unissued stock for the purpose of effecting conversions of the
Notes such number of its duly authorized shares of Common Stock as shall from
time to time be sufficient to effect such exercises and if at any time the
number of authorized but unissued shares of Common Stock shall not be sufficient
to effect such exercises at the exercise price then in effect the Company will
take such corporate action as may, in the opinion of its counsel, be necessary

prior written notice to the Company of his intention to do so. The notice by the
holder shall specify the Notes proposed to be sold or otherwise disposed of and
describe in reasonable detail the amount of the proposed sale or other
disposition and shall be accompanied by an opinion (in form and substance
reasonably satisfactory to the Company's counsel) of the holder's securities
counsel addressed to the Company as to whether the proposed sale or other

his counsel files with the Securities and Exchange Commission regarding the sale
or other disposition will immediately be provided by him or his counsel to the

Notes under the Act is necessary, no such sale or other disposition may be
effected by him other than as contemplated by a Registration Statement filed
under the Act which has become effective under such Act.

          The holder of the Notes may not sell or otherwise transfer the Notes
purchased hereunder without the transferee agreeing to be bound by the
provisions of the Subscription Agreement pursuant to which the holder of the
Notes is bound.  A copy of such Subscription Agreement may be obtained from the
Company at its principal executive offices.

     If the variable interest rate is not applicable and if this note is payable
on demand, Bank reserves, and is hereby granted the right, to adjust the
interest rate from time to time by furnishing Maker with written notice of such
adjusted rate, provided, however, that no such adjusted rate shall exceed the
maximum rate allowed, from time to time, by law.

     Additions to, reductions or exchanges of, or substitutions for the
Collateral, payments on account of this note or increases of the same, or other
loans made partially or wholly upon the Collateral, may from time to time, be
made without affecting the provisions of this note.

     If Bank deems itself insecure, or upon the happening of any of the
following events, each of which shall constitute a default hereunder, all
liabilities of each Maker to Bank shall thereupon or thereafter, at the option
of the Bank, without notice or demand, become due and payable:  (a) failure of
any Obligor (which term shall mean and include each Maker, endorser, surety and
guarantor of this note) to perform any agreement hereunder, to pay interest
hereon when due or requested or demanded or to pay any other liability
whatsoever to Bank when due; (b) the death of any Obligor; (c) the filing of any
petition under the Bankruptcy Code or any similar federal or state statute, by
or against any Obligor; (d) an application for the appointment of a receiver or
the making of a general assignment for the benefit of creditors by, or the
insolvency of any Obligor; (e) the entry of a judgment against any Obligor; (f)
the issuing of any writ of attachment or writ of garnishment, or the filing of
any lien, against the property of any Obligor; (g) the taking of possession of
any substantial part of the property of any Obligor at the instance of any
governmental authority; (h) the dissolution, merger, consolidation, or
reorganization of any Obligor; (i) the assignment by any Maker of any equity in
any of the Collateral without the written consent of Bank.

     Bank is hereby given a lien upon and a security interest in all property of
each Maker now or at any time hereafter in the possession of Bank in any
capacity whatsoever, including but not limited to any balance or share of any
deposit, trust, or agent account as security for the payment of this note, and a
similar lien upon and security interest in all such property of each Maker as
security for the payment of all other liabilities of each Maker to Bank
(including liabilities of each Maker and any other person); and Bank shall have
the same rights as to such property as it has with respect to the Collateral.

     If Bank deems itself insecure or upon the occurrence of any default
hereunder Bank shall have the remedies of a secured party under the Uniform
Commercial Code and, without limiting the generality of the foregoing, Bank
shall have the right, immediately and without further action by it, to set off
against this note all money owed by Bank in any capacity to each or any Obligor,
whether or not due, and also to set off against all other liabilities of each
Maker to Bank all money owed by Bank in any capacity to each or any Maker; and
Bank shall be deemed to have exercised such right of set-off and to have made a
charge against any such money immediately upon the occurrence of such default
even though such a charge is made or entered on the books of Bank subsequent
thereto.  Unless the Collateral is perishable or threatens to decline speedily
in value or is of a type customarily sold on a recognized market, the Bank will
give Maker reasonable notice of the time and place of any public sale thereof or
of the time after which any private sale or any other intended disposition
thereof is to be made.  The requirement of reasonable notice shall be met if
such notice is mailed, postage prepaid, to any Maker at the address given below
or at any other address shown on the records of the Bank, at least five days
before the time of the sale or disposition.  Upon disposition of any Collateral
after the occurrence of any default hereunder, Maker shall be and remain liable
for any deficiency; and Bank shall account to Maker for any surplus, but Bank
shall have the right to apply all or any part of such surplus (or to hold the
same as a reserve against) any and all other liability of each or any Maker to
bank.  The Obligors, jointly and severally, promise and agree to pay all costs
and expenses of collection and reasonable attorneys' fee, including costs,
expenses and reasonable attorneys' fees on appeal, if collected by legal
proceedings or through an attorney at law.  Maker hereby waives any right to a
trial by jury in any civil action arising out of, or based upon, this note or
the Collateral.

     Bank shall exercise reasonable care in the custody and preservation of the
Collateral to the extent required by applicable statute and shall be deemed to
have exercised reasonable care if it takes such action for that purpose as Maker
shall reasonably request in writing, but no omission to do any act not requested
by Maker shall be deemed a failure to exercise reasonable care, and no omission
to comply with any request of Maker shall of itself be deemed a failure to
exercise reasonable care.  Bank shall not be bound to take any steps necessary
to preserve any rights in the Collateral against prior parties and Maker shall
take all necessary steps for such purposes.  Bank or its nominee need not
collect interest on or principal of any Collateral or give any notice with
respect to it.

     If the Collateral shall at any time become unsatisfactory to Bank, Maker
shall within one day after demand pledge and deposit with Bank as part of the
Collateral additional property which is satisfactory to Bank.

     Bank shall have the right, which may be exercised at any time whether or
not this note is due, to notify the Obligors on any collateral to make payment
to Bank on any amounts due or to become due thereon.  In the event of any
default hereunder, Bank shall thereafter have, but shall not be limited to, the
following rights:  (i) to pledge or transfer this note and the Collateral and
Bank shall thereupon be relieved of all duties and responsibilities hereunder
and relieved from any and all liability with respect to any Collateral so
pledged or transferred, and any pledgee or transferee shall for all purposes
stand in the place of Bank hereunder and have all the rights of Bank hereunder;
(ii) to transfer the whole or any part of the Collateral into the name of itself
or its nominee; (iii) to vote the Collateral; (iv) to demand, sue for, collect,
or make any compromise or settlement it deems desirable with reference to the
Collateral; and (v) to take control of any proceeds of Collateral.

     No delay or omission on the part of Bank in exercising any right hereunder
shall operate as a waiver of such right or of any other right under this note.
Presentment, demand, protest, notice of dishonor, and extension of time without
notice are hereby waived by each and every Obligor.  Any notice to Maker shall
be sufficiently served for all purposes if placed in the mail, postage prepaid,
addressed to or left upon the premises at, the address shown below or any other
address shown on the Bank's records.

extensions or renewals thereof or any security therefor or to any party liable
thereunder or hereunder (including but not limited to failure or refusal to

that any of the provisions of said note may be modified; all without notice to
or consent of and without affecting the liability of the undersigned as
endorsers and sureties, and further consent and agree that any of the
undersigned may be sued by the holder hereof with or without joining any of the
other endorsers or makers of said note and without first or contemporaneously
suing any such other persons, or otherwise seeking or proceeding to collect from

   COMPUTER SCIENCE INNOVATIONS, INC., a Florida Corporation
   -----------------------------------------------------------------------------
                                                        (Name(s) of Borrower(s))

of   1280 Clearmont Street, N.E., Palm Bay      Brevard County,       Florida
     ---------------------------------------------------------------------------
            (Name and Street)      (City)          (County)           (State)

herein called "Borrower",

     In consideration of loans or advances made or to be made by Bank to
Borrower, and for other value received by Borrower, the parties hereto,
intending to be legally bound, agree as follows:

     1.   As used herein: (a) "Account" means an immediate right to payment for
goods sold and for goods leased and for services rendered, or any of them, and
includes a right to payment under a contract whether or not it has been earned
by performance.  "Qualified Account" means an Account which has been due less
than ninety (90) days; (b) "Inventory" means goods held for sale or lease or
     -----------
being processed for sale or lease in Borrower's business, as now or hereafter
conducted, including all materials, goods and work in process, finished goods,
and other tangible property now owned or hereafter acquired and held for sale or
lease or furnished or to be furnished under contracts of service or used or
consumed in Borrower's business; (c) "Goods" means all articles of tangible
personal property, sold, supplied, or otherwise disposed of, represented by an
Account; (d) "Purchaser" includes the buyer of goods from Borrower, the customer
for which services have been rendered or materials furnished by Borrower, or the
party with whom Borrower has contracted; (e) "Borrower" includes all
corporations and all individuals executing this agreement as parties hereto and
all members of a partnership when Borrower is a partnership, each of whom shall
be jointly and severally liable individually and as partners hereunder; (f)
"security interest" means an interest in property which secures payment or
performance of an obligation; (g) "liability" or "liabilities" includes all
liabilities (primary, secondary, direct, contingent, sole, joint or several) due
or to become due or that may be hereafter contracted or acquired, of Borrower
(including any Borrower and any other person) to Bank.

     2.   Bank will from time to time hereafter lend Borrower, on the security
of Accounts and Inventory, or any of them, acceptable to Bank, such amounts as
Bank may determine from time to time, at such rates of interest and payable and
on such terms as Bank may from time to time specify or require, and Bank may
require that such loans, or any of them, be evidenced by one or more promissory
notes of the Borrower in form satisfactory to Bank.  For the convenience of the
Borrower, the Bank may make loans and advances to the Borrower under any
promissory note the principal face amount of which is in excess of the actual
unpaid principal balance at such time.

     3.   As security for the payment of all loans and advances now or in the
future made hereunder and for all Borrower's liabilities, including any
extensions, renewals, or changes in form of any thereof, Borrower hereby assigns
to Bank and grants to Bank a security interest in: (a) all Accounts and
Inventory owned by Borrower at  the date of this agreement; (b) all Accounts and
Inventory at any time hereafter acquired by Borrower; and (c) all proceeds of
all such Accounts and Inventory.

     4.   So long as any liability to Bank is outstanding, Borrower will not
without the prior written consent of Bank borrow from anyone except Bank on the
security of, or pledge or grant any security interest in, any Account or any of
Borrower's Inventory to anyone except Bank, or permit any lien or encumbrance to
attach to any of the foregoing, or any levy to be made thereon, or any financing
statement (except Bank's financing statement) to be on file with respect
thereto.

     5.   Borrower represents and warrants that the location where it keeps the
bulk of its Inventory is at the address specified in the preamble to this
agreement, unless a different address has been specified in the following space:

     Same
     ---------------------------------------------------------------------------
             (No. and Street)        (City)         (County)         (State)

                                      -28-

and that the office where it keeps its records concerning all of its Accounts is
at the address specified in the preamble to this agreement, unless a different
address has been specified in the following space:

                (No. and Street)      (City)      (County)          (State)

Accounts are kept.

     6.   Borrower will (a) maintain Accounts and Inventory in such quantities
that at all times  70   % of the face amount of its Qualified Accounts, less

allowable discount, plus  0  % of the cost or wholesale market value, whichever
                         ---
is lower, of its Inventory, plus 100% of the balance in the Cash Collateral
Account hereinafter referred to, or such other percentages thereof as may from
time to time be fixed by Bank upon notice to Borrower, shall be at least equal
to Borrower's liabilities to Bank; and Borrower will pay to Bank, in reduction
of its liabilities, such sums as may be necessary from time to time to maintain
such ratio; (b) collect its Accounts and sell its Inventory only in the ordinary
course of business; (c) furnish Bank at the time of each borrowing, and at such
other intervals as Bank may prescribe, with a Borrower's Certificate (in such

Accounts and Inventory; (e) pay and discharge when due all taxes, levies and

such companies and against such risks as may be satisfactory to or required by
Bank; pay the cost of all such insurance; and deliver certificates evidencing
such insurance to Bank; and Borrower assigns to Bank all right to receive
proceeds of such insurance.

one or more of the following requirements, Borrower will (a) give Bank
assignments, in form acceptable to Bank, of specific Accounts or groups of
Accounts, and of moneys due and to become due under specific contracts; (b)

information relating thereto as the Bank may specify or require; (d) make no
change in any assigned Accounts or in any Account arising out of a contract
assigned to Bank, and make no material change in the terms of any such contract;
(e) furnish to Bank all information received by Borrower affecting the financial
standing of any Purchaser whose Account has been assigned to Bank; (f) receive
as the sole property of Bank and hold as trustees for Bank all moneys, checks,
notes, drafts, and other property (herein called "items of payment")
representing the proceeds of any Account or Inventory in which Bank has a
security interest, which comes into the possession of Borrower; and deposit all
such items of payment immediately in the exact form received in a special
account of Borrower in Bank entitled "Cash Collateral Account" in which account
Bank shall have a security interest to secure all Borrower's liabilities and
with respect to which account Bank alone shall have power of withdrawal; (g) pay
Bank the amount loaned against any Account assigned to Bank where the goods are
returned by the Purchaser, or where the contract is canceled or terminated; (h)
immediately notify Bank if any of its contracts arise out of contracts with the
United States or any department, agency, or instrumentality thereof, and execute
any instruments and take any steps required by Bank in order that all moneys due
and to become due under any such contract shall be assigned to Bank and notice
thereof given to the Government under the Federal Assignment of Claims Act; (i)
deliver to Bank with appropriate endorsement or assignment, as Bank may require,

Account as security and may charge any deposit account of Borrower with any such
amounts; (c) join with Bank in executing a financing statement, notice
affidavit, or similar instrument in form satisfactory to Bank, and such other
instruments as Bank may from time to time request; and pay the cost of filing
the same in any public office deemed advisable by Bank; and (d) give Bank such
financial statements, reports, certificates, lists of Purchasers (showing names,
addresses, and amounts owing), and other data concerning its Accounts,
contracts, collections, inventory and other matters as Bank may from time to
time specify; and permit Bank or its nominee to examine all of Borrower's
records relating thereto at any time, and to make extracts therefrom, and to
inspect and check Borrower's Inventory.

     9.   Borrower warrants (a) in connection with each Account covered by the
agreement: (i) it constitutes a Qualified Account as defined herein is not

request) or has delivered to Bank shipping or delivery receipts evidencing

invoice or statement delivered to Bank is owing to Borrower; (iii) the title

person, except Borrower, has any claim thereto, or, with the sole exception of
Purchaser, to the goods; (v) no partial payment has been made by anyone; and
(vi) no set-off or counterclaim to such Account exists and no agreement has been
made with any person under which any deduction or discount may be claimed,
except regular discounts allowed by Borrower for prompt payments; (vii) it
arises under an existing binding written contract between Borrower and
Purchaser; and (b) in connection with its Inventory: that Borrower is and will
be the absolute owner thereof, free and clear of all encumbrances and security
interests other than the Bank's security interest.

     10.  Borrower shall pay Bank such interest as may be specified in any note
evidencing a loan or advance made hereunder and such service charges as may be
agreed upon and shall pay to Bank all costs and expenses, including attorneys'
fees, incurred by it in the preservation or collection of collateral.  Changes
in interest rate and service charges may be made by Bank from time to time,
notwithstanding the interest rate specified in any note evidencing a loan or
advance hereunder, upon notice to Borrower and shall become effective on the
date therein specified.

     11.  Bank shall have the right at any time and from time to time, without
notice, to (a) apply any part or all the moneys in the Cash Collateral Account
representing collected items against any liability of borrower to Bank, and Bank
shall upon demand by Borrower make such application against such liability or
liabilities as Bank may itself select; (b) release to Borrower such part of the
moneys in the Cash Collateral Account as Bank may elect; (c) charge to

Accounts and of any Inventory; (f) compromise, extend, or renew any Account or
deal with the same as it may deem advisable; (g) make exchanges, substitutions
or surrenders of collateral; (h) insure inventory to its satisfaction if
Borrower fails to do so and pay for the same, and pay, for the account of
Borrower, any taxes, levies, or other charges affecting Borrower's inventory or
upon or on account of the Security Agreement or any liability or any writing
evidencing any liability, which Borrower fails to pay, and any such payment
shall constitute a liability of Borrower.

     12.  Until default, Borrower may use its inventory in any lawful manner not
inconsistent with this agreement and with the terms of insurance thereon; may
sell its inventory in the ordinary course of business; and may use and consume
any raw materials or supplies, the use and consumption of which is necessary in
order to carry on Borrower's business.

     13.  If at any time any warranty, representation, certificate or statement
of Borrower is not true, or if any liability or any part or instalment thereof
or interest thereon is not paid when due, or if any event of default as defined
in any note or other evidence of liability held by Bank should occur, or if
Borrower should fail to observe or perform any agreement or term hereof, or if
Bank at any time feels insecure for any reason whatsoever, Bank may, at its
option, thereupon or thereafter declare all liabilities of Borrower to Bank, or
any of them selected by Bank (notwithstanding any provisions thereof),
immediately due and payable without demand or notice of any kind and the same
thereupon shall immediately become and be due and payable without demand or
notice (but with such adjustments, if any, with respect to interest or other
charges as may be provided for in the promissory note or other writing
evidencing such liability), and Bank may, in addition to any other rights and
remedies which it may have, immediately and without demand, exercise any and all
the rights and remedies granted to a secured party upon default under the
Florida Uniform Commercial Code; and upon request or demand of Bank, Borrower
shall, at its expense, assemble Borrower's Inventory and make it available to
Bank at a convenient place acceptable to Bank; and Borrower shall promptly pay
to Bank any and all costs and expenses, including legal expenses and reasonable
attorney's fees incurred or paid by Bank in protecting and enforcing liabilities
and the rights of Bank hereunder, including Bank's right to take possession of
Borrower's Inventory and the proceeds of Accounts and Inventory, and to hold,
prepare for sale, sell and dispose of such Inventory.  Any notice of sale,
disposition or other intended action by Bank, sent to Borrower at the address
specified in the preamble to this agreement, or such other address of Borrower
as may from time to time be shown on Bank's records, at least five days prior to
such action, shall constitute reasonable notice to Borrower.  Upon disposition
by Bank of any property in which Bank has a security interest hereunder, or upon
collection by Bank of the proceeds of Accounts, Borrower shall be and remain
liable for any deficiency; and Bank shall account to Borrower for any surplus,
but Bank shall have the right to apply all or any part of such surplus (or to
hold the same as a reserve against) all or any liabilities of Borrower to Bank,
whether or not they, or any of them, be then due, without marshalling of assets
and in such order of application as Bank may from time to time elect.

     14.  Borrower waives protest of all commercial paper at any time held by
Bank on which borrower is in any way liable, notice of non-payment at maturity
of any and all Accounts, and except where required hereby or by law, notice of
action taken by Bank; and hereby ratifies and confirms whatever Bank may do.

     15.  No waiver by Bank of any default shall operate as a waiver of any
other default or of the same default on a future occasion.  No delay or omission
on the part of Bank in exercising any right or remedy shall operate as a waiver
thereof, and no single or partial exercise by Bank of any right or remedy shall
preclude any other or further exercise thereof or the exercise of any other
right or remedy.  Time is of the essence of this agreement.  The provisions of
this agreement are cumulative and in addition to the provisions of any liability
and any note or other writing evidencing any liability secured by this
agreement, and Bank shall have all 

                                      -30-
<PAGE>
 
the benefits, rights and remedies of and under any liability and any note or
other writing evidencing any liability secured hereby. If more than one party
shall execute this agreement, the term "Borrower" shall mean all parties signing
this agreement and each of them, and all such parties shall be jointly and
severally obligated and liable hereunder. The singular pronoun, when used
herein, shall include the plural, and the neuter shall include the masculine and
feminine. All rights of Bank hereunder shall inure to the benefit of its
successors and assigns; and all obligations of Borrower shall bind the heirs,
executors, administrators, successors and assigns of each Borrower.

     16.  Borrower releases Bank from all claims for loss or damage caused by
any failure to collect any account or enforce any contract or by any act or
omission on the part of Bank, its officers, agents and employees, except willful
misconduct.

     17.  This agreement may be terminated by either party giving the other
written notice of intention to terminate on a date named in said notice, mailed
to the last known address of the party to whom such notice is addressed; but no
such termination shall in any way affect the rights and liabilities of the
parties hereunder relating to loans or advances made, Accounts, Inventory or
other property pledged prior to the date named in such notice.

     18.  This agreement has been delivered in the State of Florida and shall be
construed in accordance with the laws of Florida.  Wherever possible, each
provision of this agreement shall be interpreted in such manner as to be
effective and valid under applicable law, but if any provision of this agreement
shall be prohibited by or invalid under applicable law, such provision shall be
ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this
agreement.

     IN WITNESS WHEREOF, this agreement has been duly executed as of the date
hereinabove first written.

of credit in the amount of $500,000 subject to the following conditions:

BORROWER:           Computer Science Innovations, Inc.

AMOUNT:             $500,000

PURPOSE:            To fund short term working capital needs.

TERMS:              Interest payable monthly, principal due on demand.

REVIEW DATE:           June 30, 1997

INTEREST RATE:         Fully floating at SunTrust Bank, Inc.'s Prime Rate.
                       SunTrust Bank's Prime Rate is currently 8.25%.

           Prime Rate is defined as the annual interest rate announced by
           SunTrust Bank, Inc. from time to time, as the prime rate (which
           interest rate is only a bench mark, is purely discretionary and is
           not necessarily the best or lower rate charged borrowing customers of
           any subsidiary bank of SunTrust Banks Inc.) Any such change in prime
           rate shall be effective at the beginning business day on which such
           change is announced; provided however, that the interest rate charged
           hereunder shall never exceed the maximum rate allowed, from time to
           time, by law.

                                  In the event that there is an outstanding
                                  balance, the company will be restricted from
                                  distributions, dividends, intercompany loans,

LOAN AGREEMENT MODIFICATION

     THIS AGREEMENT, MADE AND ENTERED INTO THIS 5TH DAY OF SEPTEMBER, L996, BY
AND BETWEEN COMPUTER SCIENCE INNOVATIONS, INC., HEREINAFTER REFERRED TO AS
"COMPANY", AND SUNTRUST BANK, CENTRAL FLORIDA, NA FORMERLY KNOWN AS SUN BANK,
NATIONAL ASSOCIATION, HEREINAFTER REFERRED TO AS "BANK".

                              W I T N E S S E T H:
                              ------------------- 

     WHEREAS, on January 8, 1991, COMPANY and BANK entered into a loan agreement
which provided for the COMPANY to borrow from the BANK the sum of ONE MILLION
AND 00/100 ($1,000,000.00) DOLLARS in a revolving line of credit as an operating
line; and

     WHEREAS, this revolving line of credit has been modified on several
occasions by the parties; and

     WHEREAS, the current revolving line of credit is ONE HUNDRED FIFTY FIVE
THOUSAND AND 00/100 ($155,000.00) DOLLARS and COMPANY has requested BANK to
increase the line of credit from ONE HUNDRED FIFTY FIVE THOUSAND AND 00/100
($155,000.00) DOLLARS to FIVE HUNDRED THOUSAND AND 00/100 ($500,000.00) DOLLARS
and BANK has agreed to such increase upon the terms and conditions set forth
below.

     NOW THEREFORE, in consideration of the mutual covenants and promises of the
parties and other good and valuable consideration the receipt and sufficiency of
which is hereby acknowledged, it is hereby agreed as follows:

     1.   The foregoing recitals are true and incorporated herein by reference.

     2.   The revolving line of credit referred to as Loan "A" as described in
          the loan agreement of January 8, 1991, as modified, is hereby
          increased from ONE HUNDRED FIFTY FIVE THOUSAND AND 00/100
          ($155,000.00) DOLLARS to FIVE HUNDRED THOUSAND AND 00/100
          ($500,000.00) DOLLARS. The interest rate shall be SunTrust Bank,
          Inc's, prime rate, fully floating. SunTrust Bank, Inc's, prime rate is
          currently 8.25%. Prime rate is defined as the annual interest rate
          announced by SunTrust Bank, Inc, from time to time as the prime rate
          (which interest rate is only a benchmark, is purely discretional and
          is not necessarily the best or lower rate charged borrowing customers
          of any subsidiary bank of SunTrust Bank, Inc). Any such change in
          prime rate shall be effective at the beginning of the business day in
          which such change is announced; provided however, that the interest
          rate charged hereunder shall never exceed the maximum rate allowed,
          from time to time, by law. Monthly payments of interest only shall be
          due and payable to BANK by COMPANY. The principal balance and accrued
          interest of the line of credit shall be due on demand.

          reduced to ZERO ($0.00) for a period of thirty (30) consecutive days
          each year.

     4.   Advances on the line of credit will be governed by a borrowing base to
          include eighty (80%) percent of accounts receivable less than ninety
          (90) days, excluding bonded and non assigned/acknowledged government
          receivables. The borrowing base will include ninety (90%) percent of
          direct assigned/acknowledged U.S. Government contracts.

     5.   The financial loan covenants are as follows:

          a.  Minimum Current Ratio        1.25:1.00

         required reports are not received by BANK as set forth in the loan
         agreement, as modified.

         management fees to Ashton Technology Group, Inc. In the event that this
         loan is in default or there is an outstanding balance on the line of
         credit, then COMPANY covenants and agrees that it will not pay to
         Ashton Technology Group, Inc., any distributions, dividends or
         management fees and it will not make any intercompany loans or other
         capital withdrawals to Ashton Technology Group, Inc., without BANK's
         prior written consent which consent shall not be unreasonably withheld.

     8.  COMPANY shall maintain its primary deposit relationship with SunTrust

     Notice to Cosigner:  You are being asked to guarantee this debt.  Think
carefully before you do.  If the Borrower doesn't pay the debt, you will have
to.  Be sure you can afford to pay if you have to, and that you want to accept
responsibility.

     You may have to pay up to the full amount of the debt if the borrower does
not pay.  You may also have to pay late fees or collection costs, which increase
this amount.

     The Bank can collect this debt from you without first trying to collect
from the borrower,  The Bank can use the same collection methods against you
that can be used against the borrower, such as suing you, garnishing your wages,
etc.  If this debt is ever in default, that fact may become a part of your
                                                                      ----

     If the variable interest rate is not applicable and if this note is payable
on demand, Bank reserves, and is hereby granted the right, to adjust the
interest rate from time to time by furnishing Maker with any written notice of
such adjusted rate, provided however, that no such adjusted rate shall exceed
the maximum rate allowed, from time to time, by law.

     Additions to, reductions or exchanges of, or substitutions for the
Collateral, payments on account of this note or increases of the same or other
loans made partially or wholly upon the Collateral, may from time to time, be
made without affecting the provisions of this note.

     If the Bank deems itself insecure, or upon the happening of any of the
following events, each of which shall constitute a default hereunder, all
liabilities of each Maker to Bank shall thereupon or thereafter, at the option
of the Bank, without notice or demand, become due and payable: (a) failure of
any Obligor (which term shall mean and include each Maker, endorser, surety and
guarantor of this note) to perform any agreement hereunder to pay interest
hereon when due or requested or demanded or to pay any other liability
whatsoever to Bank when due; (b) the death of any Obligor; (c) the filing of any
petition under the Bankruptcy Code, or any similar federal state statute, by or
against any Obligor; (d) an application for the appointment of a receiver or the
making of a general assignment for the benefit of creditors by, or the
insolvency of any Obligor; (e) the entry of a judgment against any Obligor; (f)
the issuing of any writ of attachment or writ of garnishment, or the filing of
any lien, against the property of any Obligor; (g) the taking of possession of
any substantial part of the property of any Obligor at the instance of any
governmental authority; (h) the dissolution, merger, consolidation, or
reorganization of any Obligor; (i) the assignment of any Maker of any equity in
any of the Collateral without the written consent of Bank.

     Bank is hereby given a lien upon and a security interest in all property of
each Maker now or at any time hereafter in the possession of bank in any
capacity whatsoever, including but not limited to any balance or share of any
deposit, trust, or agent account as security for the payment of this note, and a
similar lien upon the security interest in all such property of each maker as
security for the payment of all other liabilities of each Maker to Bank
including liabilities of each Maker and any other person); and Bank shall have
the same rights as to such property as it has with respect to the Collateral.

     If Bank deems itself insecure or upon the occurrence of any default
hereunder Bank shall have the remedies of a secured party under the Uniform
Commercial Code and, without limiting the generality of the foregoing, Bank
shall have the right, immediately and without further action by it, to set off
against this note all money owed by Bank in any capacity to each or any Obligor,
whether or not due, and also to set off against all other liabilities of each
maker to bank all money owed by Bank in any capacity to each or any Maker; and
Bank shall be deemed to have exercised such right of set-off and to have made a
charge against any such money immediately upon the occurrence of such default
even though such a charge is made or entered on the books of the bank subsequent
thereto.  Unless the Collateral is perishable or threatens to decline speedily
in value or is of a type customarily sold on a recognized market, the Bank will
give Maker reasonable notice of the time and place of any public sale thereof or
of the time after which any private sale or any other intended disposition
thereof is to made.  The requirement of reasonable notice shall be met if such
notice is mailed, postage prepaid, to any Maker at the address given below or at
any other address shown on the records of the Bank, at least five days before
the time of the sale or disposition.  Sale at a wholesale dealers' auction is a
commercially reasonable disposition.  Upon disposition of any Collateral after
the occurrence of any default hereunder, Maker shall be and remain liable for
any deficiency; and Bank shall account to Maker for any surplus, but Bank shall
have the right to apply all or any part of such surplus (or to hold the same as
a reason against) any and all other liability of each or any Maker to Bank. The
obligors, jointly and severally, promise and agree to pay all costs and expenses
of collection and reasonable attorney's fee, including costs expenses and
reasonable attorneys' fees on appeal, if collected by legal proceedings or
through an attorney at law, Maker hereby waives any right to a trial by jury in
any civil action arising out of, or based upon, this note or the Collateral.

     Bank shall exercise reasonable care in the custody and preservation of the
Collateral to the extent required by applicable statute, and shall be deemed to
have exercised reasonable care if it takes such action for that purpose as Maker
shall reasonably request in writing, but no omission to do any act not requested
by maker shall be deemed a failure to exercise reasonable care, and no omission
to comply with any request of Maker shall of itself be deemed a failure to
exercise reasonable care.  Bank shall not be bound to take any steps necessary
to preserve any rights in the Collateral against prior parties and maker shall
take all necessary steps for such purposes.  Bank or its nominee need not
collect interest on or principal of any Collateral or give any notice with
respect to it.

     If the Collateral shall at any time become unsatisfactory to Bank, Maker
shall within one day after demand pledge and deposit with Bank as part of the
Collateral additional property which is satisfactory to Bank.

     Bank shall have the right, which may be exercised at any time whether or
not this note is due, to notify the Obligors on any Collateral to make payment
to bank on any amounts due to become due thereon.  In the event of any default
hereunder, Bank shall thereafter have, but not be limited to, the following
rights; (i) to pledge or transfer this note and the Collateral and bank shall
thereupon be relieved of all duties and responsibilities hereunder and relieved
from any and all liability with respect to any Collateral so pledged or
transferred, and any pledgee or transferee shall for all purposes stand in the
place of the Bank hereunder and have all the rights of the bank hereunder, (ii)
transfer the whole or any part of the Collateral into the name of itself or its
nominee, (iii) to vote the Collateral; (iv) to demand, sue for, collect, or make
any compromise or settlement it deems desirable with reference to the
Collateral; and (v) to take control of any proceeds of Collateral.

     I HEREBY CONSENT TO THE ATTACHMENT OR GARNISHMENT OF MY EARNINGS..

     No delay or omission on the part of Bank in exercising any right hereunder
shall operate as a waiver of such right or any other right under this note,
Presentment, demand, protest, notice of dishonor, and extension of time without
notice are hereby waived by each and every Obligor.  Any notice to Maker shall
be sufficiently served for all purposes if placed in the mail, postage prepaid,
addressed to or left upon the premises at, the address shown below or any other
address shown on the Bank's records.

     I waive any and all privilege and rights which I may have under Chapter 47,
Florida Statutes, relating to venue, as it now exists or may hereafter be
amended:  I agree that any action shall be brought in the County in which the
Bank's business office is located as designated above or at which the loan was
closed.

HEREWITH, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER
VERBAL OR WRITTEN) OR ACTIONS OF ANY PART HERETO.  THIS PROVISION IS A MATERIAL
INDUCEMENT FOR BANK ENTERING INTO THIS AGREEMENT.  FURTHER, MAKER HEREBY
CERTIFIES THAT NOR REPRESENTATIVE OR AGENT OF BANK NOR THE BANK'S COUNSEL HAS
REPRESENTED, EXPRESSLY OR OTHERWISE, THAT BANK WOULD NOT, IN ANY EVENT OF SUCH
LITIGATION, SEEK TO ENFORCE THIS WAIVER OF RIGHT TO JURY TRIAL PROVISION.  NO
REPRESENTATIVE OR AGENT OF THE BAN NOR BANK'S COUNSEL HAS THE AUTHORITY TO
WAIVE, CONDITION, OR MODIFY THIS PROVISION.

     That certain Commercial Note(s) dated September 5, 1996, in the amount of
$500,000.00 herewith is supplemented by adding the following:

and save and keep Bank free and harmless from the payment of the same and all

thereof, whether affixed to any realty or not, shall be and remain personal
property), or to become an accession to other goods or property, or (f) locate
Collateral on any property not owned or controlled by Borrower, without the
prior written consent of the Secured Party.

     7.   Borrower will (a) at all times keep the Collateral insured in amounts
not less than the full insurable value thereof, against loss, damage, theft, and
such other risks as Secured Party may require in such companies, under such
policies, in such form and for such periods, as shall be satisfactory to Secured

Insurance Premium Refund will be credited to Borrower by the Secured Party.

Experience Rated Refunds due to the placement and termination of such insurance,
such compensation and/or refund shall be paid to Secured Party. Any interest
earned during the period of placement of such insurance may be retained by
Secured Party.

     8.   (a) Borrower will not use the Collateral or permit the same to be used
in violation of any statute, law or ordinance;

<PAGE>
 
and Secured Party may examine and inspect the Collateral at any time, wherever
located, (b) Borrower will pay promptly when due all taxes and assessments on
the Collateral or for its use of operation or upon this Agreement or upon any
note or notes or other writing evidencing the Liabilities, or any of them.

     9.   At its options, Secured Party may discharge taxes, liens or security
interest or other encumbrances at any time levied or placed on the Collateral,
may pay for insurance on the Collateral, and may pay for the maintenance and
preservation of the Collateral. Borrower agrees to reimburse Secured Party on
demand for any payment made, or any expense incurred, by Secured Party, pursuant
to the foregoing authorization, together with interest thereon at the highest
lawful rate and each such payment and interest thereon shall be secured by this
Security Agreement. Until default, Borrower may have possession of Collateral
and use it in any lawful manner not inconsistent with this Agreement and not
inconsistent with any policy of insurance thereon.

     10.  Borrower shall be in default under this Agreement upon the happening
of any of the following events or conditions: (a) failure or omission to pay
when due any Liability (or any installment thereof or interest thereon), or
default in the payment or performance of any obligation, covenant, agreement, or
Liability contained or referred to therein; (b) any warranty, representation, or
statement made or furnished to Secured Party by or on behalf of any Borrower
proves to have been false in any material respect when made or furnished; (c)
loss, theft, substantial damage, destruction, sale, or encumbrance to or of any
of the Collateral, or the making of any levy, seizure, or attachment thereof or
thereon; (d) any Obligor (which term as used herein, shall mean each Borrower
and each other Party primarily or secondarily or contingently liable on any of
the Liabilities) becomes insolvent or unable to pay debts as they mature or
makes an assignment for the benefit of creditors, or any proceeding (including
any proceeding in bankruptcy) is instituted by or against any Obligor alleging
that such Obligor is insolvent or unable to pay debts as they mature; (e) entry
of any judgment against any Obligor; (f) death of an Obligor who is a natural
person, or of any partner of any Obligor which is a partnership; (g)
dissolution, merger or consolidation, or transfer of a substantial part of the
property of any Obligor which is a corporation or partnership; (h) appointment
of a receiver for the Collateral or any part thereof or for any property in
which any Borrower has an interest; (i) the Collateral is used by anyone to
transport or store goods the possession, transportation or use of which is
illegal.

     11.  Upon the occurrence of any such default or at any time thereafter, or
whenever the Secured Party feels insecure for any reason whatsoever, Secured
Party may, at its option, declare all Liabilities secured hereby, or any of them
(notwithstanding any provisions thereof), immediately due and payable without
demand or notice of any kind and the same thereupon shall immediately become and
be due and payable without demand or notice (but with such adjustments, if any,
with respect to interest or other charges as may be provided for in the
promissory note or other writing evidencing such Liability), and Secured Party
shall have and may exercise from time to time any and all rights and remedies of
a Secured Party under the Uniform Commercial Code and any and all rights and
remedies available to it under any other applicable law; and upon request or

includes a right to payment under a contract whether or not it has been earned
by performance.  "Qualified Account" means an Account which has been due less
than ________________________ days; (b) "Inventory" means goods held for sale or
lease or being processed for sale or lease in Borrower's business, as now or
hereafter conducted, including all materials, goods and work in process,
finished goods, and other tangible property now owned or hereafter acquired and
held for sale or lease or furnished or to be furnished under contracts of
service or used or consumed in Borrower's business; (c) "Goods" means all
articles of tangible personal property, sold, supplied, or otherwise disposed
of, represented by an Account; (d) "Purchaser" includes the buyer of goods from

     2.   Bank will from time to time hereafter lend Borrower, on the security
of Accounts and Inventory, or any of them, acceptable to Bank, such amounts as
Bank may determine from time to time, at such rates of interest and payable and
on such terms as Bank may from time to time specify or require, and Bank may
require that such loans, or any of them, be evidenced by one or more promissory
notes of the Borrower in form satisfactory to Bank. For the convenience of the
Borrower, the Bank may make loans and advances to the Borrower under any
promissory note the principal face amount of which is in excess of the actual
unpaid principal balance at such time.

     3.   As security for the payment of all loans and advances now or in the
future made hereunder and for all Borrower's liabilities, including any
extensions, renewals, or changes in form of any thereof, Borrower hereby assigns

Inventory owned by Borrower at the date of this agreement; (b) all Accounts and

the security of, or pledge or grant any security interest in, any Account or any
of Borrower's inventory to anyone except Bank, or permit any lien or encumbrance
to attach to any of the foregoing, or any levy to be made thereon, or any
financing statement (except Bank's financing statement) to be on file with
respect thereto.

records of its Accounts and Inventory; (e) pay and discharge when due all taxes,
levies and other charges on its Inventory; (f) keep its Inventory insured in

     15.  No waiver by Bank of any default shall operate as a waiver of any
other default or of the same default on a future occasion. No delay or omission
on the part of Bank in exercising any right or remedy shall operate as a waiver

preclude any other or further exercise thereof or the exercise of any other
right or remedy. Time is of the essence of this agreement. The provisions of
this agreement are cumulative and in addition to the provisions of any liability
and any note or other writing evidencing any liability secured by this
agreement, and Bank shall have all the benefits, rights and remedies of and
under any liability and any note or other writing evidencing any liability
secured hereby. If more than one party shall execute this agreement, the term
"Borrower" shall mean all parties signing this agreement and each of them, and
all such parties shall be jointly and severally obligated and liable hereunder.
The singular pronoun, when used herein, shall include the plural, and the neuter
shall include the masculine and feminine. All rights of Bank hereunder shall
inure to the benefit of its successors and assigns; and all obligations of

omission on the part of the Bank, its officers, agents and employees, except
willful misconduct.

written notice of intention to terminate on a date named in said notice, mailed
to the last known address of the party to whom such notice is addressed: but no
such termination shall in any way affect the rights and liabilities of the
parties hereunder relating to loans or advances made, Accounts, Inventory or
other property pledged prior to the date named in such notice.

     18.  This agreement has been delivered in the State of Florida and shall be
construed in accordance with the laws of Florida. Wherever possible, each
provision of this agreement shall be interpreted in such manner as to be
effective and valid under applicable law, but if any provision of this agreement

ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this
agreement.

          (C)  Continuing Contractual Work.
               --------------------------- 

          The Borrower shall continue to perform its obligations under existing
contracts for sales and services under its ordinary course of business with the
Lender and specifically, Borrower acknowledges and agrees to pay Lender promptly
within invoice terms, which are Net 30, but in no event later than ninety (90)
days of the date of Lender's invoice for work pertaining to contract
performance.  Failure by Borrower to pay Lender within said ninety (90) days
shall constitute a breach of this Agreement.

          In the event the Lender, at the time of execution of this Agreement,
has outstanding on its books any accounts receivable from Borrower that are
ninety (90) days or more past due, Lender is authorized to and shall pay said
past due amount from the loan proceeds. For example, if on the day of loan
closing, $150,000.00 in 90-day plus receivables to Lender are outstanding,
$150,000.00 of the $500,000.00 loan proceeds shall be paid to Lender, not as a
prepayment of principal, but to satisfy said receivables, and the outstanding
balance of the Note shall remain at $500,000.00.

          Notwithstanding the above, the Lender specifically acknowledges and
agrees that UTS Invoice #13, dated November 22, 1996, in the amount of
$100,419.07, and ATED Invoice #11, dated November 22, 1996, in the amount of
$26,255.86, shall not be deemed a default hereunder unless payment on said
invoices is not received by April 22, 1997.

          Further, the Parties agree that nothing contained herein shall limit
the Borrower's ability to raise good faith disputes as to the invoices received
from the Lender. Any good faith dispute by Borrower shall not be deemed a
default hereunder. Borrower shall have thirty (30) days from the date of invoice
to raise a good faith dispute regarding said invoice. Failure by the Borrower to
raise a good faith dispute within thirty (30) days of invoice shall be deemed an
acknowledgment that said invoice is valid, due and payable.

          Borrower specifically acknowledges and agrees that amounts due under
UTS Invoice #13, dated November 22, 1996; #14, dated December 27, 1996; and #15,
dated January 24, 1997, and ATED Invoice #11, dated November 22, 1996; #12,
dated December 27, 1996; and #13, dated January 24, 1997; are not in dispute and
are due and payable.

          In the event any good faith dispute arises on any specific invoices
not referenced 

                                      -6-

above, Borrower acknowledges and agrees that the liability on the specific
invoices identified herein remain due and payable pursuant to the terms

continuing, the Lender may proceed to protect and enforce its rights or remedies

<PAGE>
 
          (E)  Rights and Remedies Not Waived.
               ------------------------------ 

          No course of dealing between the Borrower and the Lender or any
failure or delay on the part of the Lender in exercising any rights or remedies
hereunder shall operate as a waiver of any rights or remedies of the Lender and
no single or partial exercise of any rights or remedies hereunder shall operate
as a waiver or preclude the exercise of any other rights or remedies hereunder.

     9.   MISCELLANEOUS.
          ------------- 

          (A)  Waivers.
               ------- 

          The Borrower waives presentment, demand, protest, notice of default,
nonpayment, partial payments and all other notices and formalities relating to

consents to and waives notice of the granting of indulgences or extensions of
time of payment, the taking or releasing of security, the addition or release of
persons primarily or secondarily liable on or with respect to liabilities of the
Borrower to the Lender, all in such manner and at such time or times as the
Lender may deem advisable. No act or omission of the Lender shall in any way be
implied or affect any of the indebtedness or liabilities of the Borrower to the
Lender or rights of the Lender in any security.  No delay by the Lender to
exercise any right, power or remedy hereunder or under any security agreement,
and no indulgence given to the Borrower in case of any default, shall impair any
such right, power or remedy or be construed as having created a course of
dealing or performance contrary to the specific provisions of this Agreement or
as a waiver of any default by the Borrower or any acquiescence therein or as a
violation of any of the terms or provisions of this Agreement.  The Lender shall
have the right at all times to enforce the provisions of this Agreement and all
other documents executed in connection herewith in strict accordance with their
terms, notwithstanding any course of dealing or performance by the Lender in
refraining from so doing at any time.  No course of dealing between the Borrower
and the Lender shall operate as a waiver of any of the Lender's rights.

                                ---------------

$500,000.00                                            Date:  February 18, 1997

     FOR VALUE RECEIVED, the undersigned, THE ASHTON TECHNOLOGY GROUP, INC., a
Delaware corporation, (the "Maker") promises to pay to the order of COMPUTER
SCIENCE INNOVATIONS, INC., a Florida corporation, its successors and assigns
(the "Lender" or "Holder") located at 1235 Evans Road, Melbourne, FL 32904, or
elsewhere as directed from time to time in writing by the Holder hereof, the
principal sum of Five Hundred Thousand Dollars ($500,000.00), together with
interest thereof at the rate of eight and one-quarter percent (8.25%) per annum,
in lawful money of the United States of America, payable as follows:

          (a)  Interest shall accrue from the period of February 18, 1997, until
          November 18, 1997, on the principal amount at an annual rate of Eight
          and One-Quarter Percent (8.25%); and

          (b)  The principal sum of Five Hundred Thousand Dollars ($500,000.00),
          and all accrued interest thereon shall be due on November 18, 1997.

     Repayment of this Note is secured by certain shares of Class A and Class B
Common stock of Computer Science Innovations, Inc., held in escrow pursuant to
the terms of an Escrow Agreement dated of even date herewith.

     Payment not received within said twenty (20) days of the due date shall be
deemed a default under this Note.  If the undersigned defaults in the payment
hereunder, the Note shall bear interest at the rate of 15% ("default rate") on
the amount then due and payable.  Upon default for non-payment of the Note, the
entire unpaid principal balance of this obligation, together with accrued
interest, shall, at the Holders election, become immediately due and payable.

     Additionally, repayment of this Note is secured by a Short-Term Loan and
Security Agreement (the "Short-Term Loan Agreement').  It is expressly agreed
that all of the covenants, conditions and agreements of the Maker hereof under
said Short-Term Loan Agreement are made a part of this Note and shall be
included in the interpretation of this Note.  Upon the occurrence of default in
the performance or observation of any term, agreement, or condition specified in
the Short-Term Loan Agreement, other than for non-payment on the Note, Maker
shall have twenty (20) days from the date of written notice of default to cure
said default.

     In the event said default is not cured within the twenty (20) day period,
the entire unpaid principal balance of this obligation, together with accrued
interest, shall, at the Holders election, become immediately due and payable.

                                      -14-
<PAGE>
 
     Maker shall have the privilege to prepay the indebtedness evidenced hereby,
in whole or in part at any time.  Partial prepayments shall first be applied
against accrued interest then due and owing, and thereafter against principal.
Any partial prepayment shall not postpone the due date or change the amount of
any subsequent payment.

     All persons or entities now or at anytime liable for payment of this Note
hereby waive presentment, protest, notice of protest and dishonor.  The Maker
and all persons/entities liable hereunder expressly consent to any extensions or
renewals, in whole or in part, and all delays in timely payment or other
performance which Holder may grant at any time and from time to time without
limitation and without any notice or further consent of the undersigned.

     The remedies of Holder provided herein, or in the Short-Term Loan
Agreement, shall be cumulative and concurrent and may be pursued singularly,
successively, or together, at the sole discretion of Holder and may be exercised
as often as the occasion therefore shall arise.

     In the event this Note is placed in the hands of an attorney for collection
by civil action the prevailing party shall be entitled to an award of its
reasonable attorneys' fees and costs, including those on appeal.

     This Promissory Note is to be construed and enforced according to the laws
of the State of Florida or, if Holder elects the benefit thereof, applicable
Federal pre-emption laws.

          Whereas, the parties hereto are members of an affiliated group
(Affiliated Group) as defined in Section 1504(a); and

          Whereas, such Affiliated Group will file a U.S. consolidated income
tax return for its taxable year ended March 31, 1997 and is required to file
consolidated tax returns for subsequent years; and

          Whereas, it is the intent and desire of the parties hereto that a
method be established for allocating the consolidated tax liability of the
Affiliated Group among its members, for reimbursing the Parent for payment of
such tax liability, for compensating any party for use of its losses or tax
credits, and to provide for the allocation and payment of any refund arising
from a carryback of losses or tax credits from subsequent tax years.

          Now, Therefore, in consideration of the mutual covenants and promises
contained herein, the parties hereto agree as follows:

          1.   A U.S. consolidated income tax return shall be filed by the
               Parent for the tax year ended March 31, 1997, and for each
               subsequent taxable period in respect of which this Agreement is
               in effect and for which the Affiliated Group is required or
               permitted to file a consolidated tax return. Each Subsidiary
               shall execute and file such consent, elections, and other
               documents that may be required or appropriate for the proper
               filing of such returns.

          2.   For each tax period, each member of the Affiliated Group shall
               compute its tax liability in accordance with the provisions of
               Regulation (S) 1.1502-33(d)(3) with a fixed percentage of 100
               percent and shall pay such amount (including any increased
               liability allocated pursuant to such regulation above any
               liability allocated pursuant to section 1552 of the Internal
               Revenue Code) to the Parent. For purposes of this Agreement, any
               liability for alternative minimum tax shall be treated as a tax
               liability subject to this paragraph.

          3.   Payment of the consolidated tax liability for a taxable period
               shall include the payment of estimated tax installments due for
               such taxable period, and each Subsidiary shall pay to the Parent
               its share of each payment within ten days of receiving notice of
               such payment from the Parent, but in no event later than the due
               date for each such payment. Any amounts paid by a Subsidiary 
<PAGE>
 
               on account of a separate return or separate estimated tax
               payments that are credited against the consolidated tax liability
               of the Affiliated Group shall be included in determining the
               payments due from such Subsidiary. Any overpayment of estimated
               tax should be refunded to the Subsidiary. Any payments made by a
               Subsidiary to the Parent under this Agreement, including payments
               by a Subsidiary to the Parent of any estimated tax installments
               due for each taxable period, shall be paid to the Parent, even if
               the Affiliated Group as a whole does not have any consolidated
               estimated tax liability for such period.

          4.   To the extent payments received in respect of a taxable year by
               Parent pursuant to paragraph 2, above, exceed the consolidated
               tax liability for such period as a result of the absorption or
               utilization of losses, deductions, credits or similar items of
               certain members against other members' income, gain or similar
               items, then the Parent shall pay such excess amount received to
               those members whose items were absorbed or utilized in a manner
               that reasonably reflects such utilization or absorption within 10
               days of filing its consolidated federal income tax return for
               such period.

          5.   If part or all of an unused loss or tax credit is allocated to a
               member of the Affiliated Group pursuant to Regulation (S) 1.1502-
               79, and is carried back or forward to a year in which such member
               filed a separate return or a consolidated return with another
               affiliated group, any refund or reduction in tax liability
               arising from the carryback or carryover shall be retained by such
               member. Notwithstanding the above, the Parent shall determine
               whether an election shall be made not to carry back part or all
               of a consolidated net operating loss for any tax year in
               accordance with Section 172(b)(3).

          6.   If the consolidated tax liability is adjusted for any taxable
               period, whether by means of an amended return, claim for refund,
               or after a tax audit by the Internal Revenue Service, the
               liability of each member shall be recomputed to give effect to
               such adjustments, and in the case of a refund, the Parent shall
               make payment to each member for its share of the refund,
               determined in the same manner as in paragraphs 2 and 4 above,
               within ten days after the refund is received by the Parent, and
               in the case of an increase in tax liability, each member shall
               pay to the Parent its allocable share of such increased tax
               liability within ten days after receiving notice of such
               liability from the Parent.

          7.   If during a consolidated return period the Parent or any
               Subsidiary acquires or organizes another corporation that is
               required to be included in the consolidated return, then such
               corporation shall join in and be bound by this Agreement.
<PAGE>
 
          8.   This Agreement shall apply to the tax year ending March 31, 1997,
               and all subsequent taxable periods unless the Parent and the
               Subsidiaries agree to terminate the Agreement. Notwithstanding
               such termination, this Agreement shall continue in effect with
               respect to any payment or refunds due for all taxable periods
               prior to termination.

          9.   Notwithstanding any other provisions of this Agreement, payment
               of any estimated tax installment by a Subsidiary to the Parent
               under this Agreement for the tax year ending March 31, 1997 shall
               be made on or before March 31, 1997.

          10.  This Agreement shall be binding upon and inure to the benefit of
               any successor, whether by statutory merger, acquisition of
               assets, or otherwise, to any of the parties hereto, to the same
               extent as if the successor had been an original party to the
               Agreement.

          In Witness Whereof, the parties hereto have caused this Agreement to
be executed by their duly authorized representatives on March 27, 1997.

                          MEMORANDUM OF UNDERSTANDING
                                    BETWEEN
                       THE ASHTON TECHNOLOGY GROUP, INC.
                                      AND
                           E.COM INTERNATIONAL, INC.

1.   The Ashton Technology Group, Inc. ("Ashton") is engaged in the development,
commercialization and marketing of on-line transaction systems for the financial
services industry.

2.   E.Com International, Inc. ("E.Com") develops, manufactures and markets
integrated wireless mobile computing products for mobile computer users.

3.   In connection with the deployment of its on-line transaction systems Ashton
wishes to provide the users of its transaction systems with the ability to reach
its transaction systems from remote locations on a wireless basis.  The users of
Ashton's on-line transaction systems will be financial services executives and
professional securities traders, including but not limited to: institutional
money managers, institutional traders, exchange specialists, floor brokers,
block traders and NASDAQ market makers.

4.   Ashton wishes to become the exclusive distributor of E.Com's Discovery
family of products to the "professional" financial services market.  The
"professional" financial services market is defined as financial services
industry participants and their employees, corporate pension funds and their
employees, and individuals whose business is the trading of securities.

5.   E.Com desires to penetrate the "professional" financial services market and
hereby appoints Ashton as its exclusive distributor for the "professional"
financial services market.  This exclusive distribution right will expire on 31
December 2000, unless it is extended by mutual agreement.

6.   In consideration of its appointment as E.Com's exclusive distributor for
the "professional" financial services market Ashton will make the following
commitment to purchase the Discovery, or other appropriate product from E.Com.

               1998                 a minimum of 500 units
               1999                              [_] units
               2000                              [_] units

     This purchase commitment will be further refined to provide a quarterly
delivery schedule no later than November 15 of the year preceding the year of
each purchase commitment.  For the year 1998 Ashton currently anticipates taking
delivery of 100 units during each of the first and second calendar quarters and
150 units during each of the third and forth calendar quarters.

                                       2
<PAGE>
 
     In any calendar quarter that Ashton fails to meet its quarterly purchase
commitment, and is not current with its purchase commitment by the calendar
quarter following such shortfall, E.Com may at its discretion discontinue the
exclusivity distribution status of this agreement.  In any event, E.Com will
provide Ashton 30 day written notice of its intent to discontinue exclusivity
status in such an event.

     With regard to the purchase commitments for the years of 1999 and 2000,
Ashton will establish the minimum level of its purchase commitment not later
than June 30, 1998 in consultation with E.Com.  Ashton currently anticipates
that its minimum commitment for 1999 will be 1000 units.

7.   In consideration for the above purchase commitment, E.Com will sell these
units to Ashton at a price equal to 75% of E.Com's listed distributor price,
provided, however, that no distributor will receive pricing which is more
favorable than the pricing received by Ashton.

8.   In addition to the above purchase commitment Ashton will purchase the final
30 units in E.Com's proposed private placement as described in the private
placement memorandum dated September 1997.

9.   It is understood and agreed that it will be necessary to coordinate the
encryption protocols of E.Com's Discovery and its successor products with that
of Ashton's on-line transaction systems, and that each of Ashton and E.Com will
make the necessary resources available to assure the compatibility of the
respective encryption protocols.

10.  It is further understood and agreed that E.Com's Discovery will have to be
made compatible with the wireless "gateways" of Ashton's on-line transaction
systems and those of the financial market participants who subscribe to Ashton's
on-line transaction systems.  Each of Ashton and E.Com will make the necessary
resources available to assure that the Discovery, or its successor products,
will communicate with the necessary "gateways".

11.  Ashton and E.Com agree to enter into reciprocal and mutually satisfactory
confidentiality agreements with respect to each of the their technologies and
business plans.

12.  This memorandum of understanding provides an outline of a preliminary
business understanding which will be formalized in a contract following further
business discussions between the parties and due diligence.

               Any exercisable portion of the Option or the entire Option, if

     or (B) in the event the Company registers its Common Stock under the

     (or any successor form), through the written election of the Grantee to
     have shares of such Common Stock withheld by the Company from the shares
     otherwise to be received, with such withheld shares having the aggregate
     Fair Market Value on the date of exercise equal to or less than the
     Exercise Price, plus (ii) cash or certified check for any difference
     between the value of the shares so surrendered or withheld and the Exercise
     Price;

               (c) A bona fide written representation and agreement, in a form
     satisfactory to the Company, signed by the Grantee or other person then
     entitled to exercise such Option or portion thereof, stating that the
     shares of stock are being acquired for the Grantee's own account, for
     investment purposes only and without any present intention of distributing
     or reselling said shares or any of them except as may be permitted under
     the Act, and then applicable rules and regulations thereunder, and that the
     Grantee or other person then entitled to exercise such Option or portions
     thereof will indemnify the Company against and hold it free and harmless
     from any loss, damage, expense of liability resulting to the Company if any
     sale or distribution of the shares by such person is contrary to the
     representation and agreement referred to above; provided, however, that the
                                                     --------- -------          
     Company may, in its absolute discretion, take whatever additional actions
     it deems appropriate to ensure the observance

                                       5
<PAGE>
 
     and performance of such representation and agreement and to effect
     compliance with the Act and any other federal or state securities laws or
     regulations;

          (d) Full payment to the Company of all amounts which, under federal,
     state or local law, it is required to withhold and remit to any taxing
     authority upon exercise of the Option; and

     pursuant to Section 4.1 by any person or persons other than the Grantee,
     appropriate proof of the right of such person or persons to exercise the
     Option.

Without limiting the generality of the foregoing, the Company may require an
opinion of counsel acceptable to it to the effect that any subsequent transfer
of shares acquired on exercise of an Option does not violate the Act, and may
issue stop-transfer orders covering such shares.  Share certificates evidencing
stock issued on exercise of the Option shall bear an appropriate legend
referring to the provisions of subsection (c) above and the agreements herein.
The written representation and agreement referred to in subsection (c) and the
legend referred to above shall, however, not be required if the shares to be
issued pursuant to such exercise have been registered under the Act, and such
registration is then effective in respect of such shares.  The Company shall
determine acceptable methods for tendering and withholding Common Stock of the
Company as payment of the Exercise Price upon exercise of an Option and in
satisfaction of any withholding obligation and may impose such limitations and
prohibitions on the use of Common Stock of the Company to exercise an Option as
it deems appropriate, including without limitation, any limitation or
prohibition designed to avoid certain accounting consequences that may result
from the use of Common Stock of the Company as payment of the Exercise Price
upon exercise of an Option and in satisfaction of any withholding obligation.

Section 4.4 -  Conditions to Issuance of Stock Certificates
- ------------   --------------------------------------------

               The shares of stock deliverable upon the exercise of the Option,
or any portion thereof, may be either previously authorized but unissued shares
of issued shares that have then been reacquired by the Company. Such shares
shall be fully paid and nonassessable. The Company shall not be required to
issue or deliver any certificates of shares of stock purchased upon the exercise
of the Option or portion thereof prior to fulfillment of all of the following
conditions:

               (a) The admission of such shares to listing on all stock
     exchanges on which such class of stock is then listed if so required by
     such exchanges;

               (b) The completion of any registration or other qualification of
     such shares under any state or federal law or under rulings or regulations
     of the Securities and Exchange Commission or of any other governmental
     regulatory body, which the Company shall, in its absolute discretion, deem
     necessary or advisable;

                                       6
<PAGE>
 
              (c)  The obtaining of approval or other clearance from any state
     or federal governmental agency which the Company shall reasonably determine
     to be necessary or advisable;

              (d)  The payment to the Company of all amounts which, under
     federal, state or local law, it is required to withhold and remit to any
     taxing authority upon exercise of the Option; and

              (e)  The lapse of such reasonable period of time following the
     exercise of the Option as the Company may from time to time establish for
     reasons of administrative convenience.

in respect of such Option or portion thereof, the Common Stock has ceased to be
listed any national securities exchange or otherwise publicly traded (whether or
not listed on any stock exchange), the Board of Directors, in its sole
discretion, shall have the option of delivering (i) shares of Common Stock or
(ii) a cash payment in lieu of shares of Common Stock equal to the difference
between the Fair Market Value of the Common Stock and the Exercise Price,
multiplied by the number of shares of Common Stock that would have been issued
upon such exercise.

Section 4.6 -  Rights as Stockholder
- ------------   ---------------------

                The Grantee shall not be, nor have any of the rights or
privileges of a stockholder of the Company in respect of any shares purchasable
upon the exercise of the Option or any portion thereof unless and until
certificates representing such shares shall have been issued by the Company to
such Grantee.

disposition by transfer, alienation, anticipation, pledge, encumbrance,
assignment or any other means, whether such disposition be voluntary or
involuntary or by operation of law or by judgment, levy, attachment, garnishment
or any other legal or equitable proceeding (including bankruptcy) and any

     Exercise Price, plus (ii) cash or certified bank check for any difference;

          (c) A bona fide written representation and agreement, in a form
     satisfactory to the Company, signed by the Grantee or other person then

     investment purposes only and without any present intention of distributing
     or reselling said shares or any of them except as may be permitted under

     Grantee or other person then entitled to exercise such Option or portions
     thereof will indemnify the Company against and hold it free and harmless
     from any loss, damage, expense of liability resulting to the Company if any
     sale or distribution of the shares by such person is contrary to the
     representation and agreement referred to above; provided, however, that the

issue stop-transfer orders covering such shares.  Share certificates evidencing

issued pursuant to such exercise have been registered under the Act, and such
registration is then effective in respect of such shares.  The Company shall

obligation and may impose such limitations and prohibitions on the use of Common
Stock of the Company to exercise an Option as it deems appropriate, including

     of the Option as the Committee may from time to time establish for reasons
     of administrative convenience.

assets of the Company (including the exchange of such assets for the securities
of another corporation), the acquisition by another person of 80% or more of the

date of such event, of the number of shares of Common Stock to which the Option
relates exceeds the Exercise Price for the shares of Common Stock which are
subject to the Option, and that upon the occurrence of such event, such Option
shall terminate and be of no further force or effect; provided, however, that
                                                      --------  -------

<PAGE>
 
Section 4.1 - Eligibility to Exercise
- -----------   -----------------------

          During the lifetime of the Grantee (if an individual), only the
Grantee (or the Grantee's legal guardian) may exercise the Option or any portion
thereof.  After the death of the Grantee, any exercisable portion of the Option
may be exercised by the Grantee's personal representative or by any person
empowered to do so under the Grantee's will or under the then applicable laws of
descent and distribution.  During the existence of the Grantee (if an entity),
only the Grantee may exercise the Option or any portion thereof.  If the Grantee
ceases to exist as a legal entity, any exercisable portion of the option may be
exercised by any successor to all or substantially all of the Grantee's assets.

Section 4.2 - Partial Exercise
- -----------   ----------------

          Any exercisable portion of the Option or the entire Option, if then
wholly exercisable, may be exercised in whole or in part at any time prior to
the time when the Option or portion thereof becomes unexercisable under this
Agreement; provided, however, that any partial exercise shall be for whole
           --------  -------                                              
shares only.

Section 4.3 - Manner of Exercise
- -----------   ------------------

          The Option, or any exercisable portion thereof, may be exercised
solely by delivering to the Secretary or the Secretary's office all of the
following prior to the time when the Option or such portion becomes
unexercisable under this Agreement:

          (a) Notice in writing signed by the Grantee or the other person or
     entity then entitled to exercise the Option or portion thereof stating that
     the Option or portion thereof is thereby exercised, such notice complying
     with all applicable rules established by the Company;

          (b) Full payment of the Exercise Price in cash or certified bank check
     for the shares with respect to which such Option or portion thereof is
     exercised or, if acceptable to the Company, (i)(A) by surrender or delivery
     to the Company of shares of its Common Stock with an aggregate fair market
     value on the date of exercise equal to or less than the Exercise Price or
     (B) in the event the Company registers the Company's Common Stock under the
     Securities Act of 1933, as amended (the "Act"), by registration on form S-8
     (or any successor form), through the written election of the Grantee to
     have shares of such Common Stock withheld by the Company from the shares
     otherwise to be received, with such withheld shares having an aggregate
     Fair Market Value on the date of exercise equal to or less than the
     Exercise Price, plus (ii) cash or certified bank check for any difference
     between the value of the shares so surrendered or withheld and the Exercise
     Price;

          (c) A bona fide written representation and agreement, in a form
     satisfactory to the Company, signed by the Grantee or other person then
     entitled to exercise such Option or portion thereof, stating that the
     shares of stock are being acquired for the Grantee's own 

                                       4
<PAGE>
 
     account, for investment purposes only and without any present intention of
     distributing or reselling said shares or any of them except as may be
     permitted under the Act, and then applicable rules and regulations
     thereunder, and that the Grantee or other person then entitled to exercise
     such Option or portions thereof will indemnify the Company against and hold
     it free and harmless from any loss, damage, expense of liability resulting
     to the Company if any sale or distribution of the shares by such person is
     contrary to the representation and agreement referred to above; provided,
                                                                     --------
     however, that the Company may, in its absolute discretion, take whatever
     -------
     additional actions it deems appropriate to ensure the observance and
     performance of such representation and agreement and to effect compliance
     with the Act and any other federal or state securities laws or regulations;

          (d) Full payment to the Company of all amounts which, under federal,
     state or local law, it is required to withhold and remit to any taxing
     authority upon exercise of the Option; and

          (e) In the event the Option or portion thereof shall be exercised
     pursuant to Section 4.1 by any person or entity other than the Grantee,
     appropriate proof of the right of such person or entity to exercise the
     Option.

Without limiting the generality of the foregoing, the Company may require an
opinion of counsel acceptable to it to the effect that any subsequent transfer
of shares acquired on exercise of an Option does not violate the Act, and may
issue stop-transfer orders covering such shares.  Share certificates evidencing
stock issued on exercise of the Option shall bear an appropriate legend
referring to the provisions of subsection (c) above and the agreements herein.
The written representation and agreement referred to in subsection (c) and the
legend referred to above shall, however, not be required if the shares to be
issued pursuant to such exercise have been registered under the Act, and such
registration is then effective in respect of such shares.  The Company shall
determine acceptable methods for tendering and withholding Common Stock of the
Company as payment of the Exercise Price upon exercise of an Option and in
satisfaction of any withholding obligation and may impose such limitation and
prohibitions on the use of Common Stock of the Company to exercise an Option as
it deems appropriate, including, without limitation, any limitation or
prohibition designed to avoid certain accounting consequences that may result
from the use of Common Stock of the Company as payment of the Exercise Price
upon exercise of an Option and in satisfaction of any withholding obligation.

Section 4.4 - Conditions to Issuance of Stock Certificates
- -----------   --------------------------------------------

          The shares of stock deliverable upon the exercise of the Option, or
any portion thereof, may be either previously authorized but unissued shares or
issued shares that have then been reacquired by the Company.  Such shares shall
be fully paid and nonassessable.  The Company shall not be required to issue or
deliver any certificate or certificates for shares of stock purchased upon the
exercise of the Option or portion thereof prior to fulfillment of all of the
following conditions:

                                       5
<PAGE>
 
          (a) The admission of such shares to listing on all stock exchanges on
     which such class of stock is then listed if so required by such exchanges;

          (b) The completion of any registration or other qualification of such
     shares under any state or federal law or under rulings or regulations of
     the Securities and Exchange Commission or of any other governmental
     regulatory body, which the Company shall, in its absolute discretion, deem
     necessary or advisable;

          (c) The obtaining of approval or other clearance from any state or
     federal governmental agency which the Company shall reasonable determine to
     be necessary or advisable;

          (d) The payment to the Company of all amounts which, under federal,
     state or local law, it is required to withhold and remit to any taxing
     authority upon exercise of the Option; and

          (e) The lapse of such reasonable period of time following the exercise
     of the Option as the Company may from time to time establish for reasons of
     administrative convenience.

Section 4.5 - Cash Payment in Lieu of Stock
- -----------   -----------------------------

          Notwithstanding anything to the contrary contained herein, if at the
time the Option or any exercisable portion thereof is delivered for exercise to
the Company, or at any time prior to the issuance of a certificate of stock in
respect of such Option or portion thereof, the Common Stock has ceased to be
listed any national securities exchange or otherwise publicly traded (whether or
not listed on any stock exchange), the Board of Directors, in its sole
discretion, shall have the option of delivering (i) shares of Common Stock or
(ii) a cash payment in lieu of shares of Common Stock equal to the difference
between the Fair Market Value of the Common Stock and the Exercise Price,
multiplied by the number of shares of Common Stock that would have been issued
upon such exercise.

Section 4.6 - Rights as Stockholder
- -----------   ---------------------

          The Grantee shall not be, nor have any of the rights or privileges of
a stockholder of the Company in respect of any shares purchasable upon the
exercise of the Option or any portion thereof unless and until certificates
representing such shares shall have been issued by the Company to such Grantee.
