(1)  Based on the  average  of the  reported  high and low  sales  prices of the
     Common Stock as reported on The NASDAQ  SmallCap Market of the NASDAQ Stock
     Market,  Inc.  on June  26,  1998,  estimated  solely  for the  purpose  of
     calculating the registration fee pursuant to Rule 457(c) and (g).

(2)  Included in this amount are (i) 2,896,350  shares  issuable upon conversion
     of the  Registrant's  Series D Convertible  Preferred  Stock (the "Series D
     Preferred"),   (ii)  1,810,218  shares  issuable  upon  conversion  of  the
     Registrant's   Series  E  Convertible   Preferred   Stock  (the  "Series  E
     Preferred"),  (iii)  200,000  shares  issuable  upon  the  exercise  of the
     Registrant's   Warrants   issued  in  connection   with  the  sale  of  the
     Registrant's   Series  C  Convertible   Preferred   Stock  (the  "Series  C
     Warrants"),   (iv)  880,000  shares  issuable  upon  the  exercise  of  the

     issuable upon the exercise of certain put rights  granted to the Registrant
     in connection  with the sale of the Series D&E  Preferred  (the "Series D&E

<PAGE>


     Common Stock to be included in this Registration Statement,  the Registrant
     calculated  200% of the  number  of  shares of  Common  Stock  issuable  in
     connection with the conversion of the Series D and Series E Preferred,  the
     exercise  of the  Series D and Series E Warrants  and the  exercise  of the
     Series D&E Puts by the  Registrant.  In addition to the shares set forth in
     the table, the amount to be registered includes an indeterminate  number of
     shares  issuable  upon  the  conversion  of,  or in  respect  of,  Series D
     Preferred and Series E Preferred, and/or the exercise of, or in respect of,
     the Series C Warrants, Series D Warrants, Series E Warrants, and the Series
     D&E Puts to which the registrable  securities relate, as such number may be
     adjusted as a result of stock splits,  stock dividends,  and  anti-dilution
     provisions  (including  floating rate conversion prices) in accordance with
     Rule 416.

     The Registrant  hereby amends this  Registration  Statement on such date or
     dates as may be necessary to delay its effective  date until the Registrant
     shall  file  a  further  amendment  which  specifically  states  that  this
     Registration Statement shall thereafter become effective in accordance with
     Section  8(a) of the  Securities  Act of 1933 or  until  this  Registration
     Statement  shall become  effective on such date as the  Commission,  acting
     pursuant to Section 8(a), may determine.

                           DESCRIPTION OF THE COMPANY

     The Company is engaged in the development and  commercialization of on-line
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
as follows: (1) Universal Trading Technologies,  Inc.,  ("UTTC(TM)");  (2) Gomez
Advisors,  Inc. ("GA"); (3) Electronic Market Center, Inc. ("eMC(TM)");  and (4)
ATG(TM)  International,  Inc. ("ATG(TM)  International") (not yet incorporated).
REB Securities,  Inc. ("REB"), a broker-dealer whose Registration Statement with
the Commission is pending, is a wholly-owned subsidiary of UTTC(TM).

     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   the   professional   investment   community   which   includes
broker-dealers,  pension plan sponsors, institutional money managers, and mutual
funds.  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.  UTTC(TM)  has
developed the Universal Trading System ("UTS(TM)"),  which incorporates advanced
computer and telecommunications  technology, and 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.

     On April 22, 1995 the Philadelphia Stock Exchange (the "PHLX") and UTTC(TM)
agreed to deploy the UTS(TM) as a facility of the PHLX.  On  September  18, 1995
UTTC(TM) and PHLX  memorialized the agreement in a formal contract for a term of
five years  commencing  from the date UTS(TM)  becomes  operational on the PHLX.
Operation of the system is contingent  upon approval by the Commission of a rule
proposal filed by the PHLX. The contract  provides,  among other things, for the
development of the VTS(TM) system as a new trading product of the PHLX.

     The Company has developed a working system in accordance with contract with
the PHLX. On April 16, 1998 the SEC proposed new rules and rule amendments that,
if adopted, will permit, among other things,  alternate trading systems ("ATSs")
to choose whether to register as national securities  exchanges,  or to register
as  broker-dealers.  If adopted,  the SEC  regulations  may allow the Company to
introduce its products, regardless of whether the PHLX rule proposal is approved
by the Commission.  Anticipating adoption of these new regulations,  the Company
currently is exploring the best structure for launching its  electronic  trading
products  being  developed,  e.g. as an existing  facility of a self  regulatory
organization  ("SRO"), a broker-dealer,  or as a new and independent  registered
exchange.

     The PHLX  recently  entered  into an  agreement  pursuant to which the PHLX
would,  in essence be acquired by the American Stock Exchange (the "AMEX").  The
Company's  contract with the PHLX is assignable by its terms with the consent of
both parties to the contract.  The Company presently does not intend to agree to
the assignment of the contract.

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.

     Electronic  Market Center,  Inc.  ("eMC(TM)") is a wholly owned  subsidiary
that expected to operate and market the Company's  to-be-developed  open finance
system.  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 is a wholly owned  broker-dealer  subsidiary  of UTTC(TM) . REB expects
that,  upon approval of its application  for  registration  with the Commission,
NASD,  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.

     The  Company  currently  is in  the  process  of  forming  a  wholly  owned
subsidiary,  ATG(TM)  International,  Inc. The  international  markets represent
potentially  significant growth 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.  On November 6,
1997, the Company sold CSI(R) to an Employee Stock Ownership Plan controlled by,
and for the benefit of, CSI(R)'s management and employees.

     Following the sale of CSI(R),  revenues for the Company have  significantly
decreased,  with GA providing the only revenue  since this sale.  Except for GA,
all of the  subsidiaries  described above are in the  development  stage and are
subject to significant risks associated with development stage businesses.  None
of the subsidiaries other than GA has realized any revenue to date.

                                  RISK FACTORS

     In addition to the other information contained or incorporated by reference
in  this  Prospectus,   prospective  investors  should  consider  carefully  the
following  risk  factors in  evaluating  the  Company  and its  business  before
purchasing Common Stock. The following  discussion  identifies important factors
that could cause  Ashton's  actual  results to differ  materially  from  results
predicted or implied in any  forward-looking  statements made in this Prospectus
or elsewhere by or on behalf of Ashton.

     Dependence Upon Former Subsidiary;  Limited Operating History;  Accumulated
Deficit.  From its inception in 1994 until its  acquisition of Computer  Science
Innovations,  Inc.  ("CSI(R)"),  a  former  subsidiary,  in 1995,  Ashton  was a
development stage company with no operating history. The Company operated CSI(R)
as a subsidiary  until November 6, 1997, when the Company  consummated its sale.
CSI(R) is a software  development company  headquartered in Melbourne,  Florida,
which assisted in the design of the Ashton Technology Encryption Device ("ATED")
and the  development of the server which handles the ATED. The Company has since
determined that CSI(R) no longer fits into its long-range  strategic plan. Other
than through  CSI(R),  the Company has  generated  revenues only through GA. The
Company  has  never  realized  any  operating   profit  and  has  a  significant
accumulated  deficit. The Company is unable to predict whether or when its other
subsidiaries and/or product lines will begin to generate revenue.

     UTTC(TM)'s   Reliance  Upon  its  Agreement  with  the  Philadelphia  Stock
Exchange;  New Regulatory  Environment.  UTTC(TM) is a development stage company
which has generated no revenue to date. On April 22, 1995, UTTC(TM) and the PHLX
agreed to deploy the UTS(TM) as a facility of the exchange.  In September  1995,
UTTC(TM) and the PHLX  memorialized the agreement into a formal contract whereby
the PHLX agreed to employ the UTS(TM)  system on its equity  trading floor for a
term of five years from the first date that the UTS(TM)  system is available for
trading  (the "PHLX  Agreement").  Although  UTTC(TM)  completed  the design and
development  of the UTS(TM) and VWAP(TM)  module in April 1997,  there can be no
assurance  that  either  will  operate as  designed or that PHLX will obtain the
regulatory  approvals  necessary  to  commence  operation  of the  UTS(TM)  as a
facility of the exchange.

     The  operation of the UTS(TM) as a facility of the PHLX is  dependent  upon
regulatory  approval by the  Commission.  Section  19(b) of the Exchange Act and
Rule l9b-4  thereunder  require the PHLX to file any proposed  rule changes with
the Commission.  The concept of the UTS(TM) , which would  constitute a new PHLX
facility accompanied by new PHLX rules, must be filed as a proposed rule change.
The PHLX  filed its  proposal  for a rule  change,  which was  published  in the
Federal  Register on  September 4, 1996.  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 national  securities  exchanges.
On October 28, 1997,  the PHLX filed an  amendment to the proposed  rule change.
The  Commission  published a notice of the Amended rule  proposal in the Federal
Register on December 31, 1997.  There can be no  assurance  that the  Commission
will not require further amendment to the proposed PHLX rule change  application
or that the  Commission  will  approve the  proposed  rule change in the amended
form. The Company is unable to predict whether or when such approval of the PHLX
request will be received.

                                       -5-

<PAGE>


     The PHLX proposed rule change, if approved,  would authorize the conducting
of a morning  session  (the  "Morning  Session")  at the PHLX for the placing of
orders for eligible  securities through the UTS(TM) prior to the commencement of
each regular  trading  session on the PHLX's equity trading floor.  In addition,
and  separate  to  the  proposed  rule  change,  the  PHLX  has  sought  certain
interpretive and exemptive relief in connection with the operation of UTS(TM) as
a  facility.  As of the  date  hereof,  the  Commission  has  not  granted  such
interpretive  and exemptive  relief in connection with this proposed rule change
and there is no assurance that such relief will be granted by the Commission. If
Commission  approval of the proposed rule  change and grant of the  interpretive
and  exemptive  relief are not obtained,  the UTS(TM) as described  would not be
utilized at the PHLX and consequently there could be a delay in implementing the
UTS(TM)  into  an  alternative   market.   The  Company  is  currently   seeking
alternatives for the marketing and implementation of the UTS(TM),  including the
formation of its own broker-dealer subsidiary.

     On June 9, 1998, the PHLX announced that its Board of Directors  approved a
plan to merge with AMEX.  The  Company is unable to predict  the impact that the
proposed merger will have on its agreement with the PHLX.  However,  the Company
does not presently  intend to agree to the  assignment of the agreement with the
PHLX to the AMEX.

     Development  Stage Company.  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.  The  viability of the Company must be  considered in
light  of  problems  normally  encountered  in  the  early  stages  of  business
development,  and the likelihood of the successful deployment of the UTS(TM) and
other  products  must be  considered  in  light of the  problems,  difficulties,
complications  and  delays   frequently   encountered  in  connection  with  the
deployment  of new  technologies.  No assurance  can be given that such problems
will  not  arise  or  will  be  overcome  or  that  the  Company   will  achieve
profitability.

     Capital  Requirements;  Need  for  Additional  Financing.  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 along with the  exercise  of certain  put rights  which the Company
obtained in connection with the sale of the Series D and Series E Preferred will
provide  sufficient  working capital for at least the next 8 months. The Company
may need  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&E private  placements  prove to be
insufficient for the Company's continued operations. In order for the Company to
exercise the put rights,  certain  conditions must be met, of which there can be
no  assurance.  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 have rights,  preferences  or privileges  senior to those of the
holders of Common Stock.

     Competition;  Product  Acceptance.  The  UTS(TM)  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
include quality of trade  execution,  pricing and reliability of  post-execution
processing and settlement operations. Although the Company

                                       -6-

<PAGE>


believes  the  UTS(TM)  will  offer  improved   trading   performance,   trading
flexibility, and commercial benefits, there can be no assurance that the UTS(TM)
will be accepted  by an  extended  customer  base,  specifically,  institutional
investors,  or  that it will be  able  to  address  adequately  the  competitive
criteria in a manner that results in a competitive  advantage.  The UTS(TM) will
also compete with various national,  regional and foreign  securities  exchanges
for trade  execution  services.  There can be no assurance that these  exchanges
will not take steps to attempt to retain  transaction  volume or to compete with
the  UTS(TM)  system by  establishing  or creating  their own pilot  alternative
trading  systems,  which in turn,  could limit the future  growth of the UTS(TM)
system.

     The automated trade execution and analytical  services to be offered by the
UTS(TM) will also compete with services  offered by leading  brokerage firms and
other  information  service  and  transaction  processing  firms.  Many  of  the
Company's   competitors  have   substantially   greater   financial,   research,
development and other resources than the Company and many of their products have
substantial operating histories. Although the Company believes that the UTS(TM),
when operational, will offer certain competitive advantages,  UTTC(TM)'s ability
to  maintain  these  advantages  will  require   continued   investment  in  the
development  of its  services,  additional  marketing  activities  and  customer
support  services.  There  can  be no  assurance  that  the  Company  will  have
sufficient resources to continue to make this investment, other than through the
recent private placements of convertible  preferred stock, which may raise up to
$13 million,  or that the Company's  competitors  will not devote  significantly
more  resources to  competing  services.  The  electronic  product  advisory and
research services provided by GA compete with Forrester Research,  Inc., Gartner
Group, and J.D. Power & Associates.

     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  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
the 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.

     Dependence Upon Proprietary  Technology;  Intellectual Property Rights. The
Company 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.  However,  neither Ashton,  UTTC(TM) nor the Company's other
subsidiaries  currently  hold any material  patents or have filed for  copyright
protection   relating  to  current  product  lines.  The  Company  is  currently
considering  whether to patent or copyright  certain aspects of its product line
including the pricing algorithm utilized in connection with the VWAP(TM) system.
It may be possible for  unauthorized  third parties to copy or reverse  engineer
certain portions of the Company's products or obtain or use information that the
Company regards as  proprietary.  There can be no assurance that the steps taken
by the  Company  will be  adequate  to  deter  misappropriation  of  proprietary
information,  that  the  Company  will  be able to  detect  unauthorized  use of
proprietary  information,  or that the  Company  will be able to afford the high
cost required to enforce intellectual property rights. Further, no assurance can
be given that  nondisclosure and other  contractual  arrangements to protect the
Company's  proprietary  rights will not be breached,  that the Company will have
adequate  remedies  for any breach,  or that trade  secrets  will not  otherwise
become  known to or be  independently  developed  by  competitors.  Although the
Company's competitive position may be adversely affected by the unauthorized use
of its proprietary information, the Company believes that the ability to protect
fully its  intellectual  property is less  significant to the Company's  success
than are other  factors,  such as the  knowledge,  ability and experience of its
employees and its ongoing product development and customer support activities.

                                       -7-

<PAGE>


     Although the Company  believes  that the services and products it offers do
not infringe on the intellectual property rights of others, there can also be no
assurance  that third parties will not assert  infringement  claims  against the
Company in the future,  that such assertions by third parties will not result in
costly litigation, that the Company will prevail in such litigation, or that the
Company  will be able to  license  any  patents or other  intellectual  property
rights  from  third  parties  on  commercially  reasonable  terms,  if  at  all.
Litigation, in and of itself and regardless of its outcome, could also result in
substantial  cost and  diversion of resources of the Company.  Any  infringement
claim or other litigation  against or by the Company could materially  adversely
affect the Company's  business,  operating  results and  consolidated  financial
condition.

     Rapid  Changes in  Technology;  Maintaining  Technological  Advantage.  The
technologies underlying the Company's products and services are subject to rapid
evolution and change.  The Company's future success  depends,  in large measure,
upon its ability to respond quickly and successfully to  technological  advances
by developing and introducing new and improved products and services.  There can
be no  assurance  that the  Company  will be able to foresee and respond to such
advances or that  competitors,  including those with greater financial and other
resources,  will not succeed in  developing  technologies,  products or services
that could be superior to the those of the Company.

     Dependence on High Trading Volumes.  UTTC(TM)  revenues may depend upon the
volume of  securities  trading.  Securities  trading  volumes may be affected by
national and international economic and political conditions and broad trends in
business and  finance.  Any of these  factors may result in lower share  volumes
offered  through the  UTS(TM)  and  adversely  affect the  Company's  results of
operations  once the UTS(TM)  becomes  operational.  Variations  in  transaction
volume  could also cause the  Company's  operating  results  to  fluctuate  on a
quarterly basis.

     Risk of Errors  and  Malfunctions.  The  UTS(TM)  may be subject to various
risks  associated  with systems  errors and  malfunctions  and employee  errors.
Systems errors and malfunctions  which could affect any electronic  system could
result in service  interruptions.  In a competitive  environment  for electronic
equity trading execution,  investors may turn to the Company's  competitors on a
temporary  or  permanent  basis to  complete  their  trades.  Prolonged  service
interruptions  resulting  from natural  disasters  or otherwise  could result in
decreased trading volumes and the loss of customers.

     Year 2000 Compliance. The Company is assessing 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 is
currently  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.
Because of these uncertainties  regarding the failure of others, there can be no
assurance that the Year 2000 issue will not have a material  financial impact in
any future period.

     Government  Regulation.  The UTS(TM) will be subject to  regulation  by the
Commission,  the PHLX,  and other SRO's,  which are charged with  protecting the
interests of the investing  public and the integrity of the securities  markets.
Failure to comply with any rule or regulation  established by these entities may
subject  UTTC(TM) to suspension or penalties which could have a material adverse
affect on UTTC(TM) and the consolidated operations of the Company.

     On April 17,  1998,  the  Commission  proposed  new rules that would  allow
alternative  trading  systems,  such as the UTS(TM),  to register and operate as
broker-dealers  or  national  securities  exchanges  independently,  rather than
relying on a sponsoring  exchange to incorporate such alternative trading system
as a facility of the

                                       -8-

<PAGE>


exchange.  In addition,  the Commission proposed rules that would allow national
securities exchanges, such as the PHLX, to implement, for a period of two years,
pilot alternative trading systems without prior Commission approval.  Ashton and
UTTC(TM)  intend  to  take  advantage  of  opportunities  presented  by the  new
Commission  rules.  However,  there can be no assurance that the Commission will
issue such rules in final form,  whether the Commission  will alter the scope or
form of the proposed rules, or whether such rules will ultimately be adopted. In
the event such alternative trading system rules are not adopted in their current
form,  the Company will seek other avenues to implement its  electronic  trading
systems.

     Dependence  on Key  Employees.  The  Company's  success is  dependent  to a
significant   degree  upon  the  services  of  its  key  employees   Fredric  W.
Rittereiser, Robert A. Eprile, John A. Blohm, Fred S. Weingard, and Julio Gomez.
The loss of any one or more of these key employees could have a material adverse
effect  on the  Company's  operations.  Ashton  has  entered  into a  multi-year
employment  agreement with Mr.  Weingard.  In October 1995, the Company obtained
key-man term life insurance policies in the amount of $900,000 each on the lives
of Fred S. Weingard,  John A. Blohm, and Robert A. Eprile, and $5,000,000 on the
life of Fred W.  Rittereiser in November 1997. The Company further believes that
its future  success  will  depend in large part upon its  ability to attract and
retain  additional  highly-skilled  technical,  managerial,  sales and marketing
personnel. There can be no assurance that the Company will succeed in its effort
to  attract  appropriate  personnel.  Competition  for  such  personnel  in  the
information technology  development industry is intense.  Failure to attract and
retain  such  personnel  could have an  adverse  effect on the  Company  and its
subsidiaries operating results and financial condition.

     Possible  Unspecified  Acquisitions.  One of the Company's strategies is to
attempt to grow  through the  acquisition  of one or more  products or companies
focused on advanced  information  technologies.  Stockholders of the Company may
not have the power to approve or disapprove an acquisition. The Company receives
and expects to continue to receive  inquiries  as to its  interest in  acquiring
other products and companies and forming other business combinations.  There can
be no assurance  that the Company  will find  suitable  acquisitions  or that an
acquisition or other business combination can be completed upon terms acceptable
to the Company.  Additionally,  the Company may require  significant  additional
financing  to complete  any  acquisition.  There can be no  assurance  that such
financing will be available, or if it is available, that it will be available on
acceptable terms.

     No Dividends and None Anticipated.  The payment by Ashton of cash dividends
on its Common  Stock,  if any, in the future rests within the  discretion of its
Board of Directors and will depend,  among other things, upon Ashton's earnings,
its capital  requirements and its financial  condition as well as other relevant
factors.  Ashton has not paid or  declared  any cash  dividends  upon its Common
Stock since its  inception.  While there are no  contractual  limitations on the
Company's  ability to pay dividends,  by reason of its present  financial status
and its  contemplated  future  financial  requirements,  the  Company  does  not
anticipate making any cash  distributions on its Common Stock in the foreseeable
future.  The payment of dividends by the Company must also be in compliance with
the  provisions  of the General  Corporation  Law of the State of Delaware  (the
"GCL").

     Possible  Issuance of Additional  Preferred Stock.  Ashton is authorized to
issue up to  3,000,000  shares of  Preferred  Stock,  par  value  $.01 per share
("Preferred Stock"). As described in further detail herein,  Preferred Stock has
been issued in the following  series:  Series A Convertible PIK Preferred Stock;
Series B Convertible  Preferred  Stock;  Series C Convertible  Preferred  Stock;
Series D Convertible  Preferred Stock; and Series E Convertible Preferred Stock.
Further series of Preferred Stock may be issued in one or more series, the terms
of which may be  determined  at the time of issuance  by the Board of  Directors
without further action by  stockholders.  The terms of any issuance of Preferred
Stock may  include  voting  rights  (including  the right to vote as a series on
particular  matters)  which  could be  superior to those of the shares of Common
Stock,  preferences  over  the  shares  of  Common  Stock  as to  dividends  and
distributions in liquidation,  conversion and redemption  rights  (including the
right to convert into shares of Common Stock) and sinking fund provisions.  Four
series of Preferred  Stock,  in the  aggregate  837,503.15  shares are currently
outstanding  (250,000  shares of Series A, 587,500  shares of Series B, and 3.15
shares of Series  D).  Ashton  has no  current  plans  for the  issuance  of any
additional

                                       -9-

<PAGE>


series of Preferred Stock. The issuance of any additional  Preferred Stock could
affect the rights of the holders of Common  Stock and could  reduce the value of
the Common Stock.

     Possible  Dilution from Conversion of Preferred Stock. The number of shares
of  Common  Stock  issuable  upon   conversion  of  the  Company's   outstanding
Convertible  Preferred  Stock including the Series A Convertible PIK Convertible
Preferred  Stock,  Series B Convertible  Preferred  Stock,  Series D Convertible
Preferred Stock,  and Series E Convertible  Preferred Stock is not fixed and may
result  in  substantial  dilution  to  current  stockholders.  The  sales of the
underlying shares of Common Stock could adversely affect the market price of the
Common Stock.  Purchasers of Common Stock could therefore experience substantial
dilution of their  investment  upon  conversion of any or all of the outstanding
series of Convertible Preferred Stock. The shares of Convertible Preferred Stock
are not registered  and may be sold only if registered  under the Securities Act
or sold in accordance with an applicable  exemption from  registration,  such as
Rule 144.  Shares of Common  Stock into which  certain  series of the  Preferred
Stock  may be  converted  are being  registered  pursuant  to this  Registration
Statement.

     Requirements for Listing  Securities on NASDAQ SmallCap Market.  The Common
Stock and the  Warrants  have been  approved for  quotation  on NASDAQ  SmallCap
Market. The rules of NASDAQ SmallCap establish criteria for continued  quotation
of  securities  on NASDAQ  SmallCap.  While  the  Company  expects  to meet such
criteria,  there  can be no  assurance  that it will  be  able to  maintain  the
standards  for  continued  quotation.  Continued  inclusion  on NASDAQ  SmallCap
generally  requires  that: (i) the Company  maintain at least  $4,000,000 in net
tangible  assets,  (ii) the minimum  bid price of the Common  Stock be $1.00 per
share,  (iii) there be at least 750,000  shares in the public float valued at $5
million or more, (iv) the shares of Common Stock have at least two active market
makers and (v) the shares of Common  Stock be held by at least 400  holders.  If
the Company fails to meet the standards for continued quotation,  the market for
the securities may be affected adversely and holders may be unable to sell their
shares of Common Stock or Warrants.  Trading,  if any, in the  securities  would
thereafter  be  conducted  in the  over-the-counter  market in what are commonly
referred to as the "pink sheets".  If this were to occur, an investor would find
it more  difficult  to dispose of, or to obtain  accurate  quotations  as to the
price of the securities.

     "Penny Stock" Regulations. The Commission has adopted regulations under the
Exchange Act which  generally  define a "penny stock" to be any equity  security
that has a market price (as defined in the Exchange  Act) of less than $5.00 per
share or an  exercise  price of less than  $5.00 per  share,  subject to certain
exceptions.  If the securities are removed from NASDAQ  SmallCap,  at the market
prices of the Common Stock and Warrants on the date hereof,  the  securities may
be  deemed  to be  "penny  stocks"  and  become  subject  to rules  that  impose
additional  sales  practice   requirements  on  broker-dealers   who  sell  such
securities.  For any  transaction  involving a penny stock,  unless exempt,  the
rules  require  delivery,  prior to the  transaction,  of a disclosure  schedule
prepared by the Commission relating to the penny stock market. The broker-dealer
also must disclose the  commissions  payable to both the  broker-dealer  and the
registered representative, current quotations for the securities, information on
the limited market in penny stocks and, if the  broker-dealer is the sole market
maker,  the  broker-dealer  must  disclose  this  fact  and the  broker-dealer's
presumed control over the market. In addition,  the broker-dealer  must obtain a
written  acknowledgment  from the customer that such disclosure  information was
provided and must retain such acknowledgment for at least three years.  Further,
monthly  statements  must be sent disclosing  current price  information for the
penny  stock held in the  account.  While many  securities  quoted on the NASDAQ
Stock  Market  would  otherwise  be covered by the  definition  of penny  stock,
transactions  in a  non-NASDAQ  security  would be exempt  from all but the sole
market maker  provision  for: (i) securities  priced at five dollars more,  (ii)
securities  registered on a national  securities  exchange,  (iii)  securities
authorized for quotation in the NASDAQ system,  and (iv) securities whose issuer
has net  tangible  assets in  excess of  $2,000,000, if the  issuer  has been in
continuous operation for at least three years, or $5,000,000,  if the issuer has
been in  continuous  operation  for less than  three  years,  or the  issuer has
average  revenue  of at least  $6,000,000  for the last 3  years.  In  addition,
transactions in a NASDAQ  security  directly with a NASDAQ market maker for such
securities  would be subject  only to the sole market maker  disclosure  and the
disclosure with respect to commissions to be paid to the  broker-dealer  and the
registered representative.

     The above-described rules may materially adversely affect the liquidity for
the market of the  Company's  securities  should  they cease to be quoted on the
NASDAQ SmallCap Market. Such rules may also affect the ability of broker-dealers
to  sell  the  securities  and may  impede  the  ability  of  Warrantholders  or
subsequent  holders of the shares of Common Stock,  Warrants and Preferred Stock
to purchase Common Stock, to sell such securities in the secondary market.

Preferred  Stockholders  are also obligated to purchase  shares of the Company's
Common  Stock  upon the  exercise  of Put  Rights  obtained  by the  Company  in
connection with the sale of the Series D and Series E Preferred Stock.

     An indeterminate  number of shares of Common Stock,  initially 2,896,350 as
of the date of this  Prospectus,  are being  offered  for resale by the Series D
Preferred   Stockholders   upon  conversion  of  the  Series  D  Preferred.   An
indeterminate  number of shares of Common Stock,  initially  1,810,218 as of the

     The shares of Common  Stock being  offered by the Selling  Stockholders  or
their respective pledgees,  donees, transferees or other successors in interest,
may be sold in one or more transactions  (which may involve block  transactions)
on the NASDAQ  SmallCap Market or on such other market on which the Common Stock
may from time to time be trading, in privately-negotiated  transactions, through
the writing of options on the shares,  short sales or any  combination  thereof.
The sale price to the public may be the market price  prevailing  at the time of
sale, a price related

to such prevailing market price or such other price as the Selling  Stockholders
determine  from time to time.  The shares may also be sold  pursuant  to Section
4(1) of the Securities Act or Rule 144 thereunder.

     The Selling Stockholders or their respective pledgees, donees, transferees,
or other  successors  in  interest,  may also sell the  shares  of Common  Stock
directly to market makers acting as principals and/or  broker-dealers  acting as
agents  for  themselves  or their  customers.  Brokers  acting as agents for the
Selling Stockholders will receive usual and customary  commissions for brokerage
transactions,  and market makers and block purchasers purchasing the shares will
do so for their own account and at their own risk. It is possible that a Selling
Stockholder will attempt to sell shares of Common Stock in block transactions to
market  makers or other  purchasers  at a price per share which may be below the
then market  price.  There can be no assurance  that all or any of the shares of
Common  Stock  offered  hereby  will be  issued  to,  or sold  by,  the  Selling
Stockholders. The Selling Stockholders and any brokers, dealers, or agents, upon
effecting  the  sale  of  any of  the  shares  offered  hereby,  may  be  deemed
"underwriters"  as that term is defined under the Securities Act or the Exchange
Act, or the rules and regulations thereunder.

     The Selling Stockholders and any other persons participating in the sale or
distribution  of the  shares of  Common  Stock  will be  subject  to  applicable
provisions of the Exchange Act and the rules and regulations  thereunder,  which
provisions  of the Exchange  Act may limit the timing of purchases  and sales of
any other such person. The foregoing may affect the marketability of the shares.
The Company  has agreed to  indemnify  certain  Selling  Stockholders,  or their
transferees or assignees,  against certain  liabilities,  including  liabilities
under  the  Securities  Act,  or  to  contribute  to  payments  certain  Selling
Stockholders  or  their  respective  pledgees,   donees,  transferees  or  other
successors in interest, may be required to make in respect thereof.

shares owned and the number of shares to be offered for each Selling Stockholder
account,  and the  percentage of Common Stock owned by each Selling  Stockholder
before and after this Offering:

(3)  The number of shares set forth in the table  represents  an estimate of the

     Preferred  Stockholders and Warrantholders.  The actual number of shares of
     Common Stock issuable upon conversion of the Series D Preferred, and Series
     E Preferred  and the exercise of the Series C Warrants,  Series D Warrants,
     and Series E Warrants is indeterminate,  subject to adjustment and could be
     materially  less or more than such  estimated  number  depending on factors
     which  cannot be predicted  by the Company at this time,  including,  among
     other  factors,  the future  market price of the Common  Stock.  The actual
     number of shares  of Common  Stock  offered  hereby,  and  included  in the
     Registration  Statement of which this  Prospectus is a part,  includes such
     additional  number of shares of Common  Stock as may be issued or  issuable
     upon  conversion of the Series D Preferred,  and Series E Preferred and the
     exercise of the Series C Warrants, Series D Warrants, and Series E Warrants
     by  reason  of the  floating  rate  conversion  price  mechanism  or  other
     adjustment  mechanisms  described therein, or by reason of any stock split,
     stock dividend or similar transaction  involving the Common Stock, in order
     to prevent dilution,  in accordance with Rule 416 under the Securities Act.
     The  Certificates  of  Designation  governing  the Series D Preferred,  the
     Series E  Preferred,  Series C Warrants,  Series D  Warrants,  and Series E
     Warrants each contain provisions which limit the number of shares of Common
     Stock into which the shares of Series D  Preferred,  and Series E Preferred
     and the Warrants are  convertible.  Under these  provisions,  the number of
     shares  of  Common  Stock  into  which  the  Series D  Preferred,  Series E
     Preferred are  convertible  (together with any additional  shares of Common
     Stock held by these  Selling  Stockholders)  will not  exceed  4.99% of the
     Company's then outstanding Common Stock. Accordingly,  the number of shares
     of Common  Stock set  forth in the  table  for these  Selling  Stockholders
     exceeds  the  number  of  shares  of  Common   Stock  that  these   Selling
     Stockholders  could  own  beneficially  at any  given  time  through  their
     ownership of the Series D Preferred and Series E Preferred.

                          DESCRIPTION OF CAPITAL STOCK

     As of May 29, 1998, the authorized  capital stock of the Company  consisted
of  60,000,000  shares  of Common  Stock,  par value  $.01 per  share,  of which
8,677,913 were issued and outstanding,  and 3,000,000 shares of Preferred Stock,
of which 837,503.15 were issued and outstanding.

Common Stock

     Holders of Common  Stock are  entitled to one vote per share on all matters
to be voted upon by the  stockholders.  Holders of Common  Stock are entitled to
receive  such  dividends,  if any, as may be  declared  from time to time by the
Board of Directors out of funds legally available therefor. The Common Stock has
no preemptive or conversion rights or other subscription rights and there are no
redemptive or sinking  funds  provisions  applicable  to the Common  Stock.  All
outstanding  shares of Common Stock are fully paid and  non-assessable,  and all
the shares of Common Stock offered by the Company hereby will,  when issued,  be
fully paid and non-assessable.

     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
including  the  Placement  Agent  for  such  sale,  (the  "Investors"),  with  a
liquidation  preference of $10.00 per share (the "Series C  Preferred"),  for an
aggregate  purchase  price of  $1,000,000  ("Series C  Shares").  Holders of the
Series C Shares have the right to convert  each Series C Share into one share of
Common Stock at a prescribed conversion price. Each of the holders of the Series
C Preferred  exercised their conversion  rights in March and April,  1998. As of
March 31, 1998,  50,000  shares of the Series C Shares had been  converted  into
281,071 shares of ATG(TM) Common Stock. Between March 31 and April 21, 1998, the
remainder of the Series C Shares were  converted  into 314,342 shares of ATG(TM)
Common Stock. In connection with the sale of the Series C, the Investors and the
Placement Agent received  Warrants to purchase an aggregate of 200,000 shares of
Common Stock at an exercise price of 105% of the Market Price, as defined in the
Series C Certificate of Designation, for a period of five years.

     On April 2, 1998, the Company  entered into a Private Equity Line of Credit
Agreement (the "Line of Credit"),  pursuant to Regulation D under the Securities
Act with the Series D and Series E Preferred Stockholders. Pursuant to, and upon
the  satisfaction  of certain  conditions  set forth in the Line of Credit,  the
Company was granted  certain put rights allowing the Company to cause the Series
D & Series E Preferred  Stockholders  to purchase  up to  $13,000,000  in Common
Stock at certain  intervals,  and at certain  volumes and prices.  The number of
shares to be purchased is to be determined by a conversion  formula set forth in
the Line of Credit.  For purposes of this Registration  Statement,  were the put
rights to be exercised in their entirety as of June 26, 1998 at a stock price of
$3.438,  the Series D Series E  Preferred  Stockholders  would be  obligated  to
purchase 4,448,550 shares of Common Stock. In addition,  pursuant to the Line of
Credit, the Series D and Series E Preferred Stockholders and the Placement Agent
acquired Warrants to purchase, in the aggregate,  600,000 shares of Common Stock
at prices to be determined in the Line of Credit  Agreement.  In connection with
the foregoing  offerings of Preferred  Stock and the Line of Credit,  K. Ivan F.
Gothner, a director of the Company,  received $200,000 and an option to purchase
600,000  shares of Common Stock at an exercise price of $1.875 per share for his
services in structuring the investments. In addition, the Company expects to pay
Mr. Gothner additional compensation in the amount of 5% of the proceeds received
at the time of conversion in connection with these offerings.

Anti-Takeover Provisions

     The Company is subject to the  provisions  of Section  203 of the  Delaware
General  Corporation  Law. In general,  the  statute  prohibits a  publicly held
Delaware  corporation  from  engaging  in  a  "business   combination"  with  an
"interested  stockholder"  for a period of three  years  after the date that the
person became an interested  stockholder  unless (with certain  exceptions)  the
business combination or the transaction in which the person became an interested
stockholder  is  approved  in  a  prescribed  manner.   Generally,  a  "business
combination"  includes  a  merger,  asset or stock  sale,  or other  transaction
resulting in a financial benefit to the stockholder.  Generally,  an "interested
stockholder" is a person who, together with affiliates and associates,  owns (or
within  three  years  prior,  did own) 15% or more of the  corporation's  voting
stock.

     The Company's  Bylaws provide that (i) the  authorized  number of directors
may be changed only by resolution of the Board of Directors,  and (ii) directors
can  only  be  removed  with  or  without  cause  by  a  majority  vote  of  the
stockholders.  These provisions could have the effect of delaying,  deterring or
preventing a change in control of the Company or depressing  the market price of
Common Stock or discouraging  hostile bids in which  stockholders of the Company
could  receive a premium  for their  shares of  Common  Stock.  The  Company  is
considering whether to adopt additional anti-takeover measures.

Transfer Agent and Registrar

     The transfer  agent and registrar  for the Company's  Common Stock is North
American Transfer Company.

follows:

     SEVENTH:  Directors  of the  Corporation  shall not be liable to either the

     fiduciary duties unless the breach  involves:  (1) a duty of loyalty to the
     corporation or its stockholders, (2) acts or omissions not in good faith or
     which involve  intentional  misconduct  or a knowing  violation of law, (3)
     liability for unlawful  payments of dividends or unlawful stock purchase or
     redemption by the corporation, or (4) a transaction from which the director

Item 17. Undertakings

     The undersigned Registrant hereby undertakes:

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

          (i)  Include  any  Prospectus  required  by  Section  10(a)(3)  of the
     Securities Act;

          (ii) Reflect in the Prospectus any facts or events which, individually
     or  together,  represent a  fundamental  change in the  information  in the
     Registration  Statement.  Notwithstanding  the  foregoing,  any increase or
     decrease  in volume of  securities  offered (if the total  dollar  value of
     securities  offered  would not exceed  that which was  registered)  and any
     deviation from the low or high end of the estimated  maximum offering range
     may be  reflected  in the form of  Prospectus  filed  with  the  Commission
     pursuant  to Rule  424(b) if, in the  aggregate,  the changes in volume and
     price represent no more than a 20% change in the maximum aggregate offering
     price set  forth in the  "Calculation  of  Registration  Fee"  table in the
     effective Registration Statement; and.

          (iii) Include any  additional or changed  material  information on the
     plan of distribution;

     Provided,  however, that, for small business issuers, paragraphs (1)(i) and
(1)(ii) of this  section do not apply if the  Registration  Statement is on Form
S-3 or Form S-8, and the information  required in a post-effective  amendment is
incorporated  by reference  from periodic  reports  filed by the small  business
issuer under the Exchange Act.

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

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

                             Pursuant to Section 151
             of the General Corporation Law of the State of Delaware

                                   ----------

     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 January  26, 1998 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 C Convertible Preferred Stock;

     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:

                                      -1-

<PAGE>


     1. Designation, Amount and Par Value. Of the authorized but unissued shares
of Preferred Stock, 105,000 shares are designated Series C Convertible Preferred
(the "Series C  Preferred").  The Series C Preferred will have a par value equal
to $0.01 per share.

     2. Rank. The Series C 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 C Preferred
(including, without limitation, the Series A Convertible PIK Preferred Stock and
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  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 C Preferred with respect to dividend  rights or rights upon  liquidation,
dissolution and winding-up of the Corporation or both.

     3. Dividends. The holders of the shares of the Series C Preferred shall not
be entitled to dividends.

     4. Liquidation Preference.

          a) Subject  to the rights of holders of any class of capital  stock or
series  thereof  expressly  ranking  senior to the Series C 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 C  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 C Preferred  then held by such holder  (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 C 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 C 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 C  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 4,  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.

     5. Conversion.

          a)  Rights of Holder to  Convert.  The  holders  of shares of Series C
Preferred  shall  have the right to  convert  all or a portion  of the  Series C
Preferred into shares of the Common Stock, par value $.01 per share (the "Common
Stock"),  of the  Corporation  so that  each  share  of  Series C  Preferred  is
convertible  into such numbers of shares of Common Stock  determined by dividing
the Liquidation Preference of each share of Series C Preferred by the Conversion
Price.  For the  purposes  hereof,  the  Conversion  Price shall be equal to the
following:  (i) if the Market Price at the Conversion Date is less than $1.8774,
the  Conversion  Price is equal to the lessor of 75% of the Market  Price at the
Conversion  Date or $1.2516;  or (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.  For  purposes  of this  Section 5, the "Market  Price"  shall mean the
average of the  closing  bid prices per share of the Common  Stock over the five
consecutive  trading days ending on the trading day  immediately  preceding  the
date the applicable  holder of Series C Preferred Stock elects to have shares of
Series C Preferred  Stock converted (the  "Conversion  Date") (i) as reported by
the National  Association of Securities  Automated Quotation System (' NASDAQ"),
or (ii) if not  quoted  by  NASDAQ,  then as  reported  in the  over-the-counter
market;  or (iii) in the event the Common  Stock is listed on a  national  stock
exchange,  as reported on such exchange,  in each case as reported by Bloomberg,
L.P.

          Each   outstanding   share  of  Series  C  Preferred  Stock  shall  be
automatically  converted into Common Stock on January 26, 2000 (the  "Expiration
Date") in accordance with the then applicable 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 so that
immediately  following such event the holders of the Series C Preferred shall be
entitled  to receive  upon  conversion  thereof the kind and amount of shares of
securities of the  Corporation 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 C 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 5 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 is a party, other than a merger or consolidation
in which the  Corporation 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

                                      -3-

<PAGE>


subdivision  or  combination)  in,  outstanding  shares of Common Stock (or such
other  class or series of Common  Stock into which  shares of Series C Preferred
are then  convertible),  or (ii) any sale or conveyance of all or  substantially
all of the property and assets of the Corporation,  then provision shall be made
as part of the terms of such  transaction  whereby  the  holder of each share of
Series C 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 shares of Series C 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  into  which  such  shares of Series C  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 5. 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  provisions  shall be made in a certificate or
articles of incorporation or other constituent document or written instrument of
the  Corporation or the Surviving  Entity,  as the case may be, so as to provide
for the assumption by the Corporation or such Surviving  Entity, as the case may
be, of the  obligation to deliver to each holder of shares of Series C Preferred
such stock or other  securities  and property and  otherwise  give effect to the
provisions  set forth in this  paragraph.  For the purposes  hereof,  "Surviving
Entity"   means  any  entity   (other  than  the   Corporation)   surviving  any
consolidation  or merger referred to in this paragraph,  or the entity acquiring
the Corporation's assets. The provisions of this paragraph shall apply similarly
to successive consolidations, mergers, sales or conveyances.

          The  Corporation  shall give each holder of Series C  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 5.

          c)  Procedures  for  Conversion.  Any  holder  of  Series C  Preferred
electing  to convert  such shares or any portion  thereof  shall  deliver to the
Corporation at its principal office by telecopy an executed and completed Notice
of Conversion and, by express courier, the certificate representing the Series C
Preferred  Stock to the  Corporation.  Each  business  date on which a Notice of
Conversion is telecopied to and received by the  Corporation in accordance  with
the provisions  hereof shall be deemed the Conversion Date. The Corporation will
transmit the  certificates  representing  shares of Common Stock  issuable  upon
conversion  of any Series C  Preferred  Stock  (together  with the  certificates
representing  the Series C Preferred  Stock not so converted) to the holders via
express courier,  by electronic transfer or otherwise within three business days
after the Conversion Date if the Corporation has received the original Notice of
Conversion and Series C Preferred Stock  certificate  being so converted by such
date. In addition to any other  remedies  which may be available to the holders,
in the event that the  Corporation  fails for any reason to effect  delivery  of
such shares of Common Stock within such three  business day period,  the holders
will be entitled to revoke the relevant  Notice of  Conversion  by  delivering a
notice to such  effect to the  Corporation  whereupon  the  Corporation  and the
holders shall each be restored to their respective  positions  immediately prior
to delivery of such Notice of Conversion.

                                      -4-

<PAGE>


The Notice of Conversion and Series C Preferred Stock  representing  the portion
of the  shares  converted  shall be  delivered  to the  principal  office of the
Corporation at its then current address.

          In the event that the Common Stock  issuable  upon  conversion  of the
Series C Preferred Stock is not delivered  within three business days of receipt
by the Corporation of a valid Conversion Notice and the Series C Preferred Stock
to be  converted,  the  Corporation  shall pay to the  holders.  in  immediately
available funds. upon demand, as liquidated  damages for such failure and not as
a penalty,  for each share of Series C Preferred  Stock sought to be  converted,
$0.05  for  each of the  first 10 days  and  $.10  per day  thereafter  that the
conversion shares are not delivered.  Such liquidated damages shall run from the
sixth business day after the  Conversion  Date up until the time that either the
Notice of Conversion is revoked or the Common Stock has been delivered, at which
time liquidated  damages shall cease. Any and all payments  required pursuant to
this  paragraph  shall be payable  only in  immediately  available  funds to the
stockholders at the addresses indicated in the records of the Corporation.

          d) No  Fractional  Securities.  No  fractional  shares of Common Stock
shall be issued upon conversion of shares of Series C Preferred.  Instead of any
fractional  shares of Common  Stock  which  would  otherwise  be  issuable  upon
conversion of any share or shares of Series C 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 C  Preferred,  the
Corporation  shall pay any  documentary,  stamp or similar issue or transfer tax
due on the  issue  of  securities  of the  Corporation  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  enough  of such  shares  (or  other  securities  deliverable  upon
conversion)  to permit  the  conversion  of all of the Series C  Preferred  then
outstanding.  All shares of Common Stock issued upon due conversion of shares of
Series C Preferred shall be validly issued, fully paid and non-assessable.

     6. Redemption.

          a) General.  At any time and from time to time,  the  Corporation  may
redeem all or any  portion of the then  outstanding  Series C  Preferred  for an
amount in cash equal to the Conversion Price (the "Redemption  Funds"),  as such
Conversion Price is to be determined on the day prior to the date the Redemption
Notice  as  defined  below is  received  by the  holders  of  shares of Series C
Preferred  multiplied  by the  number  of shares  of  Series C  Preferred  to be
redeemed in accordance with the provisions of this Section 6.

          b) Redemption Procedure.  If the Corporation shall determine to redeem
less than all shares of the Series C  Preferred  then  outstanding  pursuant  to
paragraph a) of this Section 6, the shares to be redeemed  shall be selected pro
rata (or as nearly as may be) so that the

                                      -5-

<PAGE>


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.

          c) Notice.  Notice of every redemption pursuant to this Section 6 (the
"Redemption Notice") shall be sent by facsimile and mailed. by reputable express
courier,  not  less  than  10  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 C Preferred to be redeemed,  and, if less than all shares of
Series C 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;  and the place or places  where  such  shares  are to be
surrendered.

          d) Rights of Holders.  (i) Each holder of shares of Series C Preferred
called for redemption  shall have the right to effect the conversion as provided
in Section 5 hereof within 10 days after the date of the Redemption Notice; (ii)
if the Corporation  fails to deliver the Redemption  Funds to the holders of the
shares called for redemption on the 10th day from the date of the receipt of the
Redemption Notice by the holder,  the redemption shall be declared null and void
and the Corporation shall lose any further redemption privileges but the holders
shall  retain their right to effect the  conversion;  and (iii) if less than all
the shares  represented  by any  surrendered  certificate  are  redeemed,  a new
certificate  representing the unredeemed  shares shall be promptly issued to the
holder who surrendered such certificate.

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

     7. Voting Rights.

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

     8. 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.

                             Pursuant to Section 151
             of the General Corporation Law of the State of Delaware

                                   ----------

     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 March 31,  1998 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 D Convertible Preferred Stock;

     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:

     1. Designation, Amount and Par Value. Of the authorized but unissued shares
of  Preferred  Stock,  ten (10)  shares  are  designated  Series  D  Convertible
Preferred  (the "Series D  Preferred").  The Series D Preferred  will have a par
value equal to $0.01 per share.

     2. Rank. The Series D 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 D Preferred
(including,  without  limitation,  the Series A Convertible PIK Preferred Stock,
Series B Convertible Preferred Stock and Series C 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 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

                                      -1-

<PAGE>


securities of the Corporation  ranking senior to or pari passu with the Series D
Preferred  with  respect  to  dividend   rights  or  rights  upon   liquidation,
dissolution and winding-up of the Corporation or both.

     3. Dividends.  The holders of the shares of the Series D Preferred shall be
entitled to receive a dividend,  payable,  at the option of the Corporation,  in
cash or shares of Series D Preferred,  on each share of Series D Preferred  held
by such holders (the  "Series D Dividend")  in an amount equal to eight  percent
(8%) per annum (computed on the basis of a 360 day year of twelve 30 day months)
of the Series D Liquidation  Preference (as defined below).  Such dividend shall
be cumulative  and payable  promptly  following the end of each calendar year or
upon conversion.

     4. Liquidation Preference.

          a) Subject  to the rights of holders of any class of capital  stock or
series  thereof  expressly  ranking  senior to the Series D 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 D  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 One Million
Dollars  ($1,000,000)  for each  share of Series D  Preferred  then held by such
holder (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 D 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 D 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 D  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 4,  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 not 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.

     5. Conversion

          a)  Rights of Holder to  Convert.  The  holders  of shares of Series D
Preferred  shall  have the right to  convert  all or a portion  of the  Series D
Preferred into shares of the Common Stock, par value $.01 per share (the "Common
Stock"),  of the  Corporation  so that  each  share  of  Series D  Preferred  is
convertible  into such numbers of shares of Common Stock  determined by dividing
the Liquidation Preference of each share of Series D Preferred by the Conversion
Price defined herein (the  "Conversion  Ratio").  For the purposes  hereof,  the
Conversion  Price  shall be  equal to the  following:  the  Market  Price at the
Conversion Date as defined below  multiplied by the Applicable  Conversion Rate.
For purposes of this Section 5, the "Market Price" shall mean 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
applicable  holder of Series D Preferred Stock elects to have shares of Series D
Preferred  Stock  converted  (the  "Conversion  Date")  (i) as  reported  by the
National  Association of Securities  Automated  Quotation System ("NASDAQ");  or
(ii) if not quoted by NASDAQ, then as reported in the  over-the-counter  market;
or (iii) in the event the Common Stock is listed on a national  stock  exchange,
as reported on such  exchange,  in each case as reported by Bloomberg,  L.P. The
"Applicable    Conversion   Rate"   shall   be   seventy-five   percent   (75%).
Notwithstanding the foregoing, the Maximum Conversion Price shall be one hundred
and twenty-five percent (125%) of the

                                      -2-

<PAGE>


closing  bid price of the  Corporation's  Common  Stock on the date the Series D
Preferred  to be  converted  was  purchased.  A holder may convert the shares of
Series D Preferred in fractional  increments of not less than .05 percent (.05%)
or 1/20 of a share (such that the shares are converted in increments  which have
a Liquidation Preference equal to Fifty Thousand Dollars ($50,000.00)).

          Each   outstanding   share  of  Series  D  Preferred  Stock  shall  be
automatically  converted  into Common  Stock on March 31, 2000 (the  "Expiration
Date") in accordance with the then applicable 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  so that  immediately
following such event the holders of the Series D Preferred  shall be entitled to
receive upon  conversion  thereof the kind and amount of shares of securities of
the  Corporation 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 D 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 5 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 is a party, other than a merger or consolidation
in which the  Corporation is the surviving or continuing  corporation  and which
does not result in any  reclassification  of, or change  (other than a change in
part  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
D Preferred  are then  convertible),  or (ii) any sale or  conveyance  of all or
substantially all of the property and assets of the Corporation, then provisions
shall be made as part of the terms of such  transaction  whereby  the  holder of
each  share of  Series D  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 shares of Series D
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 into which such shares of Series
D 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 5. 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 provisions shall
be made in a  certificate  or articles  of  incorporation  or other  constituent
document or written  instrument of the Corporation or the Surviving  Entity,  as
the case may be, so as to provide for the assumption by the  Corporation or such
Surviving  Entity,  as the case may be, of the  obligation  to  deliver  to each
holder of  shares  of Series D  Preferred  such  stock or other  securities  and
property  and  otherwise  give  effect  to the  provisions  set  forth  in  this
paragraph.  For the purposes hereof,  "Surviving Entity" means any entity (other
than the Corporation)  surviving any consolidation or merger referred to in this
paragraph,  or the entity acquiring the Corporation's  assets. The provisions of
this  paragraph  shall apply  similarly to successive  consolidations,  mergers,
sales or conveyances.

          The  Corporation  shall give each holder of Series D  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 5.

                                      -3-

<PAGE>


          c)  Procedures  for  Conversion.  Any  holder  of  Series D  Preferred
electing  to convert  such shares or any portion  thereof  shall  deliver to the
Corporation  at its principal  office by  telecopying  an executed and completed
Notice of  Conversion  and,  by  express  courier  within 3 business  days,  the
certificate  representing the Series D Preferred Stock to the Corporation.  Each
business  date on which a Notice of  Conversion is telecopied to and received by
the  Corporation in accordance  with the  provisions  hereof shall be deemed the
Conversion  Date. The Corporation  will transmit the  certificates  representing
shares of Common Stock issuable upon  conversion of any Series D Preferred Stock
(together with the certificates representing the Series D Preferred Stock not so
converted)  to the  holders  via  express  courier,  by  electronic  transfer or
otherwise   within  three  business  days  after  the  Conversion  Date  if  the
Corporation  has  received  the  original  Notice  of  Conversion  and  Series D
Preferred Stock  certificate being so converted by such date. In addition to any
other  remedies  which may be available  to the  holders,  in the event that the
Corporation  fails for any reason to effect  delivery  of such  shares of Common
Stock  within such three  business  day period,  the holders will be entitled to
revoke the relevant  Notice of  Conversion by delivering a notice to such effect
to the  Corporation  whereupon  the  Corporation  and the holders  shall each be
restored to their  respective  positions  immediately  prior to delivery of such
Notice of  Conversion.  The Notice of  Conversion  and Series D Preferred  Stock
representing  the  portion of the shares  converted  shall be  delivered  to the
principal office of the Corporation at its then current address.

          In the event that the Common Stock  issuable  upon  conversion  of the
Series D Preferred Stock is not delivered  within three business days of receipt
by the Corporation of a valid Conversion Notice and the Series D Preferred Stock
to be  converted,  the  Corporation  shall pay to the  holders,  in  immediately
available funds, upon demand, as liquidated  damages for such failure and not as
a penalty,  for each share of Series D Preferred  Stock sought to be  converted,
Five Thousand Dollars ($5,000.00) for each of the first 10 days and Ten Thousand
Dollars  ($10,000.00)  per day  thereafter  that the  conversion  shares are not
delivered.  Such liquidated  damages shall run from the fifth business day after
the  Conversion  Date up until the time that either the Notice of  Conversion is
revoked or the Common Stock has been delivered, at which time liquidated damages
shall cease. Any and all payments  required  pursuant to this paragraph shall be
payable only in immediately available funds to the stockholders at the addresses
indicated in the records of the Corporation.

          d) No  Fractional  Securities.  No  fractional  shares of Common Stock
shall be issued upon conversion of shares of Series D Preferred.  Instead of any
fractional  shares of Common  Stock  which  would  otherwise  be  issuable  upon
conversion of any share or shares of Series D 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 D  Preferred,  the
Corporation  shall pay any  documentary,  stamp or similar issue or transfer tax
due on the  issue  of  securities  of the  Corporation  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  enough  of such  shares  (or  other  securities  deliverable  upon
conversion)  to permit  the  conversion  of all of the Series D  Preferred  then
outstanding.  All shares of Common Stock issued upon due conversion of shares of
Series D Preferred shall be validly issued, fully paid and non-assessable.

     6. Redemption.

          a) Definitions. For the purposes of this Section 6,

          "Applicable  Premium" means if the Redemption Date occurs:  (a) within
30 days  (inclusive)  after the date any shares of Series D Preferred are issued
(the "Issue Date"), ten percent (10%) of the liquidation preference, (b) between
31 and 60 days after the Issue Date,  twenty  percent  (20%) of the  Liquidation
Preference,  (c)  between 61 and 90 days after the Issue  Date,  thirty  percent
(30%) of the Liquidation  Preference and (d) after 90 days after the Issue Date,
the Economic Benefit.

          "Economic  Benefit"  means an amount  equal to the market value of the
shares of Preferred Stock to be redeemed assuming such shares had been converted
to Common Stock on the Redemption Notice Date in accordance with the formula set
forth above.

          "Interest"  means interest at the rate of eight percent (8%) per annum
compounded  annually on the  Liquidation  Preference  from the Issue Date to the
Redemption Date calculated as set forth in Section 3 above.

          "Redemption  Amount"  means (i) the  Redemption  Price,  plus (ii) the
Applicable Premium plus (iii) Interest.

          "Redemption  Date" means the date specified in a Redemption  Notice as
received by the holder of Series D Preferred in respect of shares to be redeemed
in accordance with this Section 6.

in accordance with this Section 6.

          b) General.  At any time and from time to time,  the  Corporation  may
redeem all or any  portion of the then  outstanding  Series D  Preferred  for an
amount  in cash  equal  to the (i)  Redemption  Amount  on the  Redemption  Date
multiplied  by (b) The number of shares of Series D Preferred  to be redeemed in
accordance with the provisions of this Section 6.

          c) Redemption Procedure.  If the Corporation shall determine to redeem
less than all shares of the Series D  Preferred  then  outstanding  pursuant  to
paragraph a) of this Section 6, 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.

          d) Notice. Notice of every redemption pursuant to this Section 6 shall
be sent by facsimile and mailed, by reputable express courier,  not less than 10
days prior to 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 D  Preferred  to be  redeemed,  and, if less than all
shares of Series D Preferred held by such holder are to be redeemed,  the number
of such shares to be redeemed from such holder; the Redemption Price, Applicable
Premium, Interest Redemption Amount applicable to the shares to be redeemed; and
the place or places where such shares are to be surrendered.

          e) Rights of Holders.  (i) Each holder of shares of Series D Preferred
called for redemption  shall have the right to effect the conversion as provided
in section 5 hereof within 10 days after the date of the Redemption Notice; (ii)
if the Corporation  fails to deliver the Redemption Amount to the holders of the
shares called for redemption on the 10th day from the date of the receipt of the
Redemption Notice by the holder,  the redemption shall be declared null and void
and the Corporation shall lose any further redemption privileges but the holders
shall  retain their right to effect the  conversion;  and (iii) if less than all
the shares  represented  by any  surrendered  certificate  are  redeemed,  a new
certificate  representing the unredeemed  shares shall be promptly issued to the
holder who surrendered such certificate.

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

     7. Voting Rights.

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

     8. General Provisions.

                                   ----------

                             Pursuant to Section 151
             of the General Corporation Law of the State of Delaware

                                   ----------

     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 March 31,  1998 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 E Convertible Preferred Stock;

     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. Designation, Amount and Par Value. Of the authorized but unissued shares
of  Preferred  Stock,  ten (10)  shares  are  designated  Series  E  Convertible
Preferred  (the "Series E  Preferred").  The Series E Preferred  will have a par
value equal to $0.01 per share.

     2. Rank. The Series E 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 E Preferred

                                      -1-

<PAGE>


(including,  without  limitation,  the Series A Convertible PIK Preferred Stock,
Series B Convertible  Preferred Stock, Series C Convertible  Preferred Stock and
Series D 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 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 E Preferred with respect to dividend  rights or rights upon  liquidation,
dissolution and winding-up of the Corporation or both.

     3. Dividends.  The holders of the shares of the Series E Preferred shall be
entitled to receive a dividend,  payable,  at the option of the Corporation,  in
cash or shares of Series E Preferred,  on each share of Series E Preferred  held
by such holders (the  "Series E Dividend")  in an amount equal to eight  percent
(8%) per annum (computed on the basis of a 360 day year of twelve 30 day months)
of the Series E Liquidation  Preference (as defined below).  Such dividend shall
be cumulative  and payable  promptly  following the end of each calendar year or
upon conversion.

     4. Liquidation Preference.

          a) Subject  to the rights of holders of any class of capital  stock or
series  thereof  expressly  ranking  senior to the Series E 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 E  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 One Million
dollars  ($1,000,000)  for each  share of Series E  Preferred  then held by such
holder (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 E 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 E 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 E  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 4,  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.

     5. Conversion.

          a)  Rights of Holder to  Convert.  The  holders  of shares of Series E
Preferred  shall  have the right to  convert  all or a portion  of the  Series E
Preferred into shares of the Common Stock, par value $.01 per share (the "Common
Stock"),  of the  Corporation  so that  each  share  of  Series E  Preferred  is
convertible

                                      -2-

<PAGE>


into such  numbers  of  shares  of  Common  Stock  determined  by  dividing  the
Liquidation  Preference  of each share of Series E Preferred  by the  Conversion
Price defined herein (the  "Conversion  Ratio").  For the purposes  hereof,  the
Conversion  Price  shall be  equal to the  following:  the  Market  Price at the
Conversion Date as defined below  multiplied by the Applicable  Conversion Rate.
For purposes of this Section 5, the "Market Price" shall mean 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
applicable  holder of Series E Preferred Stock elects to have shares of Series E
Preferred  Stock  converted  (the  "Conversion  Date")  (i) as  reported  by the
National  Association of Securities  Automated  Quotation System ("NASDAO");  or
(ii) if not quoted by NASDAQ, then as reported in the  over-the-counter  market;
or (iii) in the event the Common Stock is listed on a national  stock  exchange,
as reported on such  exchange,  in each case as reported by Bloomberg,  L.P. The
"Applicable Conversion Rate" shall be eighty percent (80%).  Notwithstanding the
foregoing,  the Maximum  Conversion Price shall be the lesser of (a) one-hundred
and  twenty-five  percent  (125%) of the closing bid price of the  Corporation's
Common  Stock on the date the  Series E  Preferred  was  purchased,  or (b) Five
Dollars  ($5.00).  A holder  may  convert  the shares of Series E  Preferred  in
fractional  increments  of not less than .05  percent  (.05%) or 1/20 of a share
(such that the shares  are  converted  in  increments  which have a  Liquidation
Preference equal to Fifty Thousand Dollars ($50,000.00)).

          Each   outstanding   share  of  Series  E  Preferred  Stock  shall  be
automatically  converted  into Common  Stock on March 31, 2000 (the  "Expiration
Date") in accordance with the then applicable 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 so that
immediately  following such event the holders of the Series E Preferred shall be
entitled  to receive  upon  conversion  thereof the kind and amount of shares of
securities of the  Corporation 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 E 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 5 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 is a party, other than a merger or consolidation
in which the  corporation is the surviving or continuing  corporation  and which
does not result in any  reclassification  of, or change  (other than a change in
par

                                      -3-

<PAGE>


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 E
Preferred  are  then  convertible),  or (ii) any  sale or  conveyance  of all or
substantially all of the property and assets of the Corporation, then provisions
shall be made as part of the terms of such  transaction  whereby  the  holder of
each  share of  Series E  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 shares of Series E
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 into which such shares of Series
E 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 5. 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 provisions shall
be made in a  certificate  or articles  of  incorporation  or other  constituent
document or written  instrument of the Corporation or the Surviving  Entity,  as
the case may be, so as to provide for the assumption by the  Corporation or such
Surviving  Entity,  as the case may be, of the  obligation  to  deliver  to each
holder of  shares  of Series E  Preferred  such  stock or other  securities  and
property  and  otherwise  give  effect  to the  provisions  set  forth  in  this
paragraph.  For the purposes hereof,  "Surviving Entity" means any entity (other
than the Corporation)  surviving any consolidation or merger referred to in this
paragraph,  or the entity acquiring the Corporation's  assets. The provisions of
this  paragraph  shall apply  similarly to successive  consolidations,  mergers,
sales or conveyances.

          The  Corporation  shall give each holder of Series E  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 5.

          c)  Procedures  for  Conversion.  Any  holder  of  Series E  Preferred
electing  to convert  such shares or any portion  thereof  shall  deliver to the
Corporation  at its principal  office by  telecopying  an executed and completed
Notice of Conversion  and, by express  courier  within three  business days, the
certificate  representing the Series E Preferred Stock to the Corporation.  Each
business  date on which a Notice of  Conversion is telecopied to and received by
the  Corporation in accordance  with the  provisions  hereof shall be deemed the
Conversion  Date. The Corporation  will transmit the  certificates  representing
shares of Common Stock issuable upon  conversion of any Series E Preferred Stock
(together with the certificates representing the Series E Preferred Stock not so
converted)  to the  holders  via  express  courier,  by  electronic  transfer or
otherwise   within  three  business  days  after  the  Conversion  Date  if  the
Corporation  has  received  the  original  Notice  of  Conversion  and  Series E
Preferred Stock  certificate being so converted by such date. In addition to any
other  remedies  which may be available  to the  holders,  in the event that the
Corporation fails for any reason to effect delivery of such

                                      -4-

<PAGE>


shares of Common Stock within such three  business day period,  the holders will
be entitled to revoke the relevant  Notice of  Conversion by delivering a notice
to such effect to the  Corporation  whereupon  the  Corporation  and the holders
shall  each be  restored  to their  respective  positions  immediately  prior to
delivery of such Notice of  Conversion.  The Notice of  Conversion  and Series E
Preferred  Stock  representing  the  portion  of the shares  converted  shall be
delivered  to the  principal  office  of the  Corporation  at its  then  current
address.

          In the event that the Common Stock  issuable  upon  conversion  of the
Series E Preferred Stock is not delivered  within three business days of receipt
by the Corporation of a valid Conversion Notice and the Series E Preferred Stock
to be  converted,  the  Corporation  shall pay to the  holders,  in  immediately
available funds, upon demand, as liquidated  damages for such failure and not as
a penalty,  for each share of Series E Preferred  Stock sought to be  converted,
Five Thousand Dollars ($5,000.00) for each of the first 10 days and Ten Thousand
Dollars  ($10,000.00)  per day  thereafter  that the  conversion  shares are not
delivered.  Such liquidated  damages shall run from the fifth business day after
the  Conversion  Date up until the time that either the Notice of  Conversion is
revoked or the Common Stock has been delivered, at which time liquidated damages
shall cease. Any and all payments  required  pursuant to this paragraph shall be
payable only in immediately available funds to the stockholders at the addresses
indicated in the records of the Corporation.

          d) No  Fractional  Securities.  No  fractional  shares of Common Stock
shall be issued upon conversion of shares of Series E Preferred.  Instead of any
fractional  shares of Common  Stock  which  would  otherwise  be  issuable  upon
conversion of any share or shares of Series E 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 E  Preferred,  the
Corporation  shall pay any  documentary,  stamp or similar issue or transfer tax
due on the  issue  of  securities  of the  Corporation  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  enough  of such  shares  (or  other  securities  deliverable  upon
conversion)  to permit  the  conversion  of all of the Series E  Preferred  then
outstanding.  All shares of Common Stock issued upon due conversion of shares of
Series E Preferred shall be validly issued, fully paid and non-assessable.

     (6) Redemption.

          a) Definitions. For the purposes of this Section 6.

          "Applicable  Premium" means if the Redemption Date occurs:  (a) within
30 days  (inclusive)  after the date any shares of Series E Preferred are issued
(the "Issue Date"), ten percent (10%) of the liquidation preference, (b) between
31 and 60 days after the Issue Date,  twenty  percent  (20%) of the  Liquidation
Preference,  (c)  between 61 and 90 days after the Issue  Date,  thirty  percent
(30%) of the Liquidation  Preference and (d) after 90 days after the Issue Date,
the Economic Benefit.

                                      -5-

<PAGE>


          "Economic  Benefit"  means an amount  equal to the market value of the
shares of Preferred Stock to be redeemed assuming such shares had been converted
to Common Stock on the Redemption  Date in accordance with the formula set forth
above.

          "Interest"  means interest at the rate of eight percent (8%) per annum
compounded  annually on the  Liquidation  Preference  from the Issue Date to the
Redemption Date calculated as set forth in Section 3 above.

          "Redemption  Amount"  means (i) the  Redemption  Price,  plus (ii) the
Applicable Premium plus (iii) Interest.

          "Redemption  Date" means the date specified in a Redemption  Notice as
received by the holder of Series E Preferred in respect of shares to be redeemed
in accordance with this Section 6.

          "Redemption  Notice"  means a notice to a holder of Series E Preferred
in accordance with this Section 6.

          "Redemption  Price" means the highest closing ask price (determined in
the same manner as the  closing  bid price in Section  5(a) above) of the Common
Stock over the five (5) day trading period ending on the Redemption Date.

          b) General.  At any time and from time to time,  the  Corporation  may
redeem all or any  portion of the then  outstanding  Series E  Preferred  for an
amount  in cash  equal  to the (i)  Redemption  Amount  on the  Redemption  Date
multiplied  by (b) the number of shares of Series E  Preferred to be redeemed in
accordance with the provisions of this Section 6.

          c) Redemption Procedure.  If the Corporation shall determine to redeem
less than all shares of the Series E  Preferred  then  outstanding  pursuant  to
paragraph a) of this Section 6, 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.

          d) Notice. Notice of every redemption pursuant to this Section 6 shall
be sent by facsimile and mailed, by reputable express courier,  not less than 10
days prior to 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 E  Preferred  to be  redeemed,  and, if less than all
shares of Series E Preferred held by such holder are to be redeemed,  the number
of such shares to be redeemed from such holder; the Redemption Price, Applicable
Premium, Interest Redemption Amount applicable to the shares to be redeemed; and
the place or places where such shares are to be surrendered.

          e) Rights of Holders.  (i) Each holder of shares of Series E Preferred
called for redemption  shall have the right to effect the conversion as provided
in section 5 hereof within 10 days after the date of the Redemption Notice; (ii)
if the Corporation  fails to deliver the Redemption Amount to the holders of the
shares called for redemption on the 10th day from the date of the receipt of the
Redemption Notice by the holder,  the redemption shall be declared null and void
and the Corporation shall lose any further redemption privileges but the holders
shall  retain their right to effect the  conversion;  and (iii) if less than all
the shares  represented  by any  surrendered  certificate  are  redeemed,  a new
certificate  representing the unredeemed  shares shall be promptly issued to the
holder who surrendered such certificate.

                                      -6-

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

     7. Voting Rights.

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

     8. General Provisions.

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

and  sub-clauses of this  Certificate  of  Designations  are for  convenience of
