Item 5.  Other Events.

      Cyber Digital, Inc., a New York corporation (the "Company"),  entered into
a Securities  Purchase  Agreement (the  "Agreement"),  dated as of September 30,
1999, with the Purchaser  named therein (the  "Purchaser")  (attached  hereto as
Exhibit 10.1).

      In connection with the Agreement,  the Company  authorized a new series of
its Preferred Stock, par value $0.05 per share, called the Series D1 Convertible
Preferred  Stock  (the  "Preferred  Stock").  As  set  forth  in  the  Company's
Certificate of Amendment to its Certificate of  Incorporation  for the Preferred
Stock  (the  "Certificate  of  Amendment")  (included  as part of the  Company's
Composite  Amended & Restated  Certificate of  Incorporation  attached hereto as
Exhibit 3.1), the Preferred  Stock is  convertible  into shares of the Company's
Common Stock, par value $0.01 per share (the "Common Stock"), at a price that is
equal to the amount  obtained by  multiplying  100% (subject to  adjustment)  by
either  (i) that  price of the  Common  Stock  which  shall be  computed  as the
arithmetic  average of the three lowest  Closing Sales Prices (as defined in the
Certificate  of  Amendment)  of the Common Stock  during the twenty  consecutive
trading days immediately  preceding the date of such  determination and (ii) the
Closing Bid Price (as defined in the  Certificate  of  Amendment)  on such date,
whichever is lower.  Such amount shall not, in any case, exceed $5.43 subject to
certain adjustments as set forth in the Certificate of Amendment.

      Pursuant to the  Agreement,  the  Purchaser  has purchased an aggregate of
3,000 shares of the  Company's  Series D1 Preferred  Stock,  par value $0.05 per
share (the "Preferred  Stock"),  and a warrant to purchase 190,678 shares of the
Company's  Common  Stock (the  "Warrant")  for an  aggregate  purchase  price of
$3,000,000  (attached  hereto as Exhibit 4.1). The price at which the Warrant is
exercisable is $5.70.

      Subject to certain conditions as set forth in the Agreement, the Purchaser
is also  required to buy and the  Company is required to sell (i) an  additional
2,000 shares of Preferred Stock and (ii) warrants to purchase a number of shares
of Common Stock based on a formula set forth in the Agreement.

      Contemporaneously  with the execution and delivery of the  Agreement,  the
parties also executed a  Registration  Rights  Agreement,  pursuant to which the
Company has agreed to provide to the Purchaser certain registration rights under
the federal securities laws and the rules and regulations promulgated thereunder
(attached hereto as Exhibit 4.2).

      In connection  with the  transaction  as set forth in the  Agreement,  the
Zanett Securities Corporation, financial advisor to the Company, has been issued
a warrant to purchase  30,000 shares of the Company's  Common Stock (the "Zanett
Warrant") in partial  consideration  for services  rendered to the Company.  The
Zanett Warrant is in a form  substantially the same as the Warrant issued to the
Purchaser and attached hereto as Exhibit 4.1.

Stock,  par value $0.05 per share which shall be called the Company's  Series D1

purchase up to a number of shares of Common Stock (as  exercised,  collectively,
the "Initial  Warrant Shares") for each share of Preferred Stock purchased equal
to the quotient of (A) 300,  divided by (B) the average of the Closing Bid Price

amounts set forth opposite each Buyer's name on the Schedule of Buyers, and (ii)

trading  days  immediately  preceding  the Initial  Closing  Date (the  "Initial
Closing").  Subject to the  satisfaction (or waiver) of the conditions set forth
in Sections 1(c), 6(b) and 7(b) below, the Company shall issue and sell and each

(as defined below), subject to satisfaction (or waiver) of the conditions to the
Mandatory  Closing set forth in Sections  6(b) and 7(b) and the  conditions  set
forth in this Section  1(c) (or such later date as is mutually  agreed to by the
Company  and  the  Buyers).  The  Company  shall  deliver  written  notice  (the
"Mandatory  Share Notice") to each Buyer on a date (the "Mandatory  Share Notice
Date") as soon as reasonably  practicable,  but in no event later than the first
business  day,  following the date that the Initial  Registration  Statement (as
defined  in  the  Registration   Rights   Agreement)   registering  the  Initial
Registrable  Securities (as defined in the  Registration  Rights  Agreement) has
been  declared  effective  by the  SEC  in  accordance  with  the  terms  of the
Registration Rights Agreement,  which date shall not be later than 90 days after
the Initial  Closing Date.  The Mandatory  Share Notice shall set forth (x) each
Buyer's pro rata portion (based on the number of Initial  Preferred  Shares such
Buyer  purchased  in relation to the total  number of Initial  Preferred  Shares
purchased  by all of  the  Buyers)  of the  aggregate  number  of the  Mandatory
Preferred Shares (which aggregate number shall be 2,000 Preferred Shares), which
such Buyer is required to purchase at such Mandatory Closing,  (y) the aggregate
Purchase Price for such Buyer's  Mandatory  Preferred Shares and (z) the date of
the Mandatory  Closing Date.  Notwithstanding  the foregoing,  no Buyer shall be
required to purchase the Mandatory Preferred Shares unless each of the following
conditions is satisfied:  (i) during the period beginning on the Mandatory Share
Notice Date and ending on and including the Mandatory  Closing Date, the Initial
Registration Statement covering the resale of the Initial Registrable Securities

conversions)  and 100% of the  Warrant  Shares  issuable  upon  exercise  of the
Initial Warrants and the Mandatory  Warrants (as if the Mandatory  Warrants were
issued and outstanding and without regard to any limitations on Exercises); (ii)
during  the  period  beginning  on the  Initial  Closing  Date and ending on and
including the Mandatory  Closing Date there shall not have occurred (A) an event

it were not cured, or (C) the  announcement of a pending Change of Control which
has not been  abandoned  or  terminated;  (iii) at all times  during  the period
beginning on the  Mandatory  Share Notice Date and ending on and  including  the
Mandatory  Closing  Date,  the  Common  Stock  shall  have been  designated  for

quotation or reporting systems;  (iv) during the period beginning on the Initial
Closing Date and ending on and including the Mandatory Closing Date, the Company
shall have delivered  Conversion  Shares upon conversion of the Preferred Shares
on a timely  basis as set  forth  in  Section  2(d)(ii)  of the  Certificate  of
Amendment  and otherwise  shall have been in compliance  with and shall not have
breached any provision of the  Transaction  Documents (as defined below) and the
Certificate of Amendment; (v) either (I) on each day during the period beginning
on the  Mandatory  Share Notice Date and ending on and  including  the Mandatory
Closing Date,  the Proxy  Condition  Trigger (as defined  below) is less than or
equal to 10% or (II)  the  Company  shall  have  received  the  approval  of the
Company's shareholders, pursuant to Section 4(l), to issue the Conversion Shares
upon the conversion of the Preferred Shares and the Warrant Shares upon exercise
of the Warrants in excess of the Exchange Cap (as defined in the  Certificate of
Amendment); and (vi) the Company shall not have previously delivered a Mandatory
Share Notice. The "Proxy Condition Trigger" means the quotient of (A) the sum of
(y) the number of  Conversion  Shares  issuable  upon  conversion of the Initial
Preferred Shares and the Mandatory Preferred Shares on the date of determination
(as if the Mandatory  Preferred  Shares were issued and  outstanding and without
regard to any  limitations  on  conversions)  and (z) the number of the  Warrant
Shares issuable upon exercise of the Initial warrants and the Mandatory Warrants
on the date of  determination  (as if the  Mandatory  Warrants  were  issued and

Buyer shall pay the Purchase  Price to the Company for the Preferred  Shares and
the  related  Warrants  to be issued  and sold to such  Buyer at the  respective

Company's written wire instructions,  and (ii) the Company shall deliver to each
Buyer,  stock  certificates  (in the  denominations as such Buyer shall request)
(the "Stock  Certificates")  representing  such number of the  Preferred  Shares
which  such  Buyer is then  purchasing  along with the  related  Warrants,  duly
executed on behalf of the Company and registered in the name of such Buyer.

         2.       BUYER'S REPRESENTATIONS AND WARRANTIES.

                  Each Buyer represents and warrants with respect to only itself
that:

                  a.  Investment  Purpose.  Such  Buyer  (i)  is  acquiring  the
Preferred Shares and the Warrants, (ii) upon conversion of the Preferred Shares,
will acquire the Conversion  Shares then issuable and (iii) upon exercise of the
Warrants,  will acquire

<PAGE>

the Warrant Shares  issuable upon exercise  thereof (the Preferred  Shares,  the
Warrants,  the  Conversion  Shares  and the  Warrant  Shares,  collectively  are
referred to herein as the "Securities"), for its own account for investment only
and not with a view towards,  or for resale in connection  with, the public sale
or distribution  thereof,  except pursuant to sales registered or exempted under
the 1933 Act;  provided,  however,  that by making the  representations  herein,
subject to certain  restrictions set forth in Section 2(g) of the Certificate of
Amendment,  such  Buyer  does not  agree to hold any of the  Securities  for any
minimum  or other  specific  term and  reserves  the  right  to  dispose  of the
Securities  at any  time  in  accordance  with  or  pursuant  to a  registration
statement or an exemption under the 1933 Act.

                  b. Accredited  Investor  Status.  Such Buyer is an "accredited
investor" as that term is defined in Rule 501(a) of Regulation D.

                  c. Reliance on  Exemptions.  Such Buyer  understands  that the
Securities  are being offered and sold to it in reliance on specific  exemptions
from the registration requirements of United States federal and state securities
laws and that the Company is relying in part upon the truth and accuracy of, and
such Buyer's  compliance  with,  the  representations,  warranties,  agreements,
acknowledgments  and  understandings  of such Buyer set forth herein in order to
determine the  availability of such exemptions and the eligibility of such Buyer
to acquire such Securities.

                  d. Information. Such Buyer and its advisors, if any, have been
furnished with all materials  relating to the business,  finances and operations
of the Company and  materials  relating to the offer and sale of the  Securities
which have been  requested by such Buyer.  Such Buyer and its advisors,  if any,
have been afforded the opportunity to ask questions of the Company. Neither such
inquiries nor any other due diligence  investigations conducted by such Buyer or
its advisors,  if any, or its representatives shall modify, amend or affect such
Buyer's right to rely on the Company's  representations and warranties contained
in Sections 3 and 9(m) below.  Such Buyer understands that its investment in the
Securities  involves a high  degree of risk and might  involve  the loss of such
buyer's entire investment. Such Buyer has sought such accounting,  legal and tax
advice as it has considered  necessary to make an informed  investment  decision
with respect to its acquisition of the Securities.

                  e. No  Governmental  Review.  Such Buyer  understands  that no
United States  federal or state agency or any other  government or  governmental
agency has passed on or made any recommendation or endorsement of the Securities
or the fairness or suitability of the investment in the Securities nor have such
authorities  passed  upon  or  endorsed  the  merits  of  the  offering  of  the
Securities.

                  f. Transfer or Resale.  Such Buyer  understands that except as
provided in the Registration Rights Agreement:  (i) the Securities have not been
and are not being  registered  under the 1933 Act or any state  securities laws,
and may not be  offered  for sale,  sold,  assigned  or  transferred  unless (A)
subsequently  registered thereunder,  (B) such Buyer shall have delivered to the
Company an opinion of

<PAGE>

counsel,  in a form reasonably  satisfactory to the Company,  to the effect that
such  Securities to be sold,  assigned or transferred  may be sold,  assigned or
transferred  pursuant to an exemption from such registration,  or (C) such Buyer
provides the Company with reasonable assurance that such Securities can be sold,
assigned or transferred  pursuant to Rule 144 promulgated under the 1933 Act (or
a successor rule  thereto)("Rule  144"); (ii) any sale of the Securities made in
reliance on Rule 144 may be made only in  accordance  with the terms of Rule 144
and further,  if Rule 144 is not applicable,  any resale of the Securities under
circumstances  in which the seller (or the person through whom the sale is made)
may be deemed to be an  underwriter  (as that term is  defined in the 1933 Act),
may require compliance with some other exemption under the 1933 Act or the rules
and  regulations  of the SEC  thereunder;  and (iii) neither the Company nor any
other person is under any obligation to register such Securities  under the 1933
Act or any state  securities  laws or to comply with the terms and conditions of
any exemption thereunder.

                  g. Legends.  Such Buyer  understands  that the certificates or
other instruments  representing the Preferred Shares and the Warrants and, until
such time as the sale of the Conversion  Shares and the Warrant Shares have been
registered  under  the  1933  Act as  contemplated  by the  Registration  Rights
Agreement,  the stock  certificates  representing the Conversion  Shares and the
Warrant Shares,  except as set forth below,  shall bear a restrictive  legend in
substantially  the  following  form  (and a  stop-transfer  order  may be placed
against transfer of such stock certificates):

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE  SECURITIES  ACT OF 1933,  AS AMENDED,  OR  APPLICABLE  STATE
         SECURITIES  LAWS. THE SECURITIES  HAVE BEEN ACQUIRED FOR INVESTMENT AND
         MAY NOT BE OFFERED  FOR SALE,  SOLD,  TRANSFERRED  OR  ASSIGNED  IN THE
         ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER
         THE SECURITIES ACT OF 1933, AS AMENDED,  OR APPLICABLE STATE SECURITIES
         LAWS, OR AN OPINION OF COUNSEL, IN FORM REASONABLY  SATISFACTORY TO THE
         COMPANY  COUNSEL,  THAT  REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR
         APPLICABLE  STATE  SECURITIES  LAWS OR UNLESS SOLD PURSUANT TO RULE 144
         UNDER SAID ACT.  NOTWITHSTANDING  THE FOREGOING,  THE SECURITIES MAY BE
         PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT.

The legend  set forth  above  shall be removed  and the  Company  shall  issue a
certificate without such legend to the holder of the Securities upon which it is
stamped, if (i) such Securities are registered for sale under the 1933 Act, (ii)
in connection with a sale transaction,  such holder provides the Company with an
opinion of counsel,  in a form reasonably  satisfactory  to the Company,  to the
effect that a public sale, assignment or transfer of such Securities may be made
without  registration  under the 1933 Act,  or (iii) such  holder  provides  the
Company  with  assurances   reasonably  acceptable  to  the

<PAGE>

Company  that such  Securities  can be sold  pursuant  to Rule 144.  Such  Buyer
acknowledges,  covenants  and  agrees to sell the  Securities  represented  by a
certificate(s)  from which the legend has been  removed,  only pursuant to (i) a
registration  statement  effective under the 1933 Act, or (ii) advice of counsel
that such sale is exempt  from  registration  required  by Section 5 of the 1933
Act.

                  h.   Authorization;   Enforcement.   This  Agreement  and  the
Registration  Rights Agreement have been duly and validly  authorized,  executed
and  delivered on behalf of such Buyer and are valid and binding  agreements  of
such Buyer  enforceable  against  such  Buyer in  accordance  with their  terms,
subject as to enforceability  to general  principles of equity and to applicable
bankruptcy,  insolvency,  reorganization,   moratorium,  liquidation  and  other
similar laws relating to, or affecting generally,  the enforcement of applicable
creditors' rights and remedies.

                  i.  Residency.  Such Buyer is a resident of that  jurisdiction

         3.       REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

                  The  Company  represents  and  warrants  to each of the Buyers
that:

                  a.  Organization  and  Qualification.   The  Company  and  its
"Subsidiaries"  (which for purposes of this Agreement  means any entity in which
the Company,  directly or  indirectly,  owns a majority of the capital  stock or
holds an equivalent  equity or similar interest) are corporations duly organized
and validly  existing in good  standing  under the laws of the  jurisdiction  in
which  they are  incorporated,  and  have  the  requisite  corporate  power  and
authorization  to own  properties  and to carry on their  business  as now being
conducted.  Each of the  Company and its  Subsidiaries  is duly  qualified  as a
foreign corporation to do business and is in good standing in every jurisdiction
in which its ownership of property or the nature of the business conducted by it
makes such qualification necessary,  except to the extent that the failure to be
so qualified or be in good standing would not have a Material Adverse Effect. As
used in this Agreement,  "Material  Adverse  Effect" means any material  adverse
effect on the business, properties, assets, operations, results of operations or
financial  condition of the Company and its Subsidiaries taken as a whole, or on
the transactions  contemplated hereby or by the agreements and instruments to be
entered  into in  connection  herewith,  or on the  authority  or ability of the
Company to perform its obligations  under the Transaction  Documents (as defined
below) or the Certificate of Amendment. A complete list of entities in which the
Company, directly or indirectly owns capital stock or holds an equity or similar
interest is set forth in Schedule 3(a).

                  b.   Authorization;   Enforcement;   Compliance   with   Other
Instruments.  (i) The Company has the requisite corporate power and authority to
enter into and perform its obligations  under this Agreement,  the  Registration
Rights  Agreement,  the Irrevocable  Transfer Agent  Instructions (as defined in
Section 5), the  Warrants and

<PAGE>

each of the other  agreements  entered into by the parties  hereto in connection
with  the  transactions  contemplated  by  this  Agreement  (collectively,   the
"Transaction  Documents"),  and to issue the  Securities in accordance  with the
terms hereof and thereof,  (ii) the  execution  and delivery of the  Transaction
Documents  by the Company and the  execution  and filing of the  Certificate  of
Amendment by the Company and the consummation by the Company of the transactions
contemplated hereby and thereby,  including without limitation,  the issuance of
the Preferred  Shares and the Warrants and the  reservation for issuance and the
issuance  of  the  Conversion  Shares  and  the  Warrant  Shares  issuable  upon
conversion or exercise thereof, have been duly authorized by the Company's Board
of Directors and no further consent or authorization is required by the Company,
its Board of Directors or its stockholders, (iii) the Transaction Documents have
been duly  executed and  delivered by the Company,  (iv) this  Agreement and the
Registration  Rights  Agreement  and,  when  executed and  delivered,  the other
Transaction  Documents,  constitute  the valid and  binding  obligations  of the
Company  enforceable  against the Company in accordance with their terms, except
as such  enforceability  may be  limited  by  general  principles  of  equity or
applicable bankruptcy,  insolvency,  reorganization,  moratorium, liquidation or
similar laws relating to, or affecting generally,  the enforcement of creditors'
rights and  remedies,  and (v) prior to the Closing  Date,  the  Certificate  of
Amendment  will have been filed with  Secretary of State of the Sate of New York
and will be in full force and effect.

                  c. Capitalization. The authorized capital stock of the Company

stock of the Company or any of its  Subsidiaries  or options,  warrants,  scrip,
rights  to  subscribe  to,  calls or  commitments  of any  character  whatsoever

Company or any of its  Subsidiaries  which  contain  any  redemption  or similar

that will be triggered by the  issuance of the  Securities  as described in this
Agreement;  and (vii) the Company does not have any stock appreciation rights or
"phantom  stock"  plans or  agreements  or any similar  plan or  agreement.  The
Company  has  furnished  to the Buyer true and correct  copies of the  Company's
Certificate  of  Incorporation,  as amended  and as in effect on the date hereof
(the "Certificate of Incorporation"), and the Company's By-laws, as in effect on
the date hereof (the  "By-laws"),  and the terms of all  securities  convertible
into or  exercisable  for Common  Stock and the  material  rights of the holders
thereof in respect thereto.

                  d.  Issuance of  Securities  . The  Preferred  Shares are duly

validly issued,  fully paid and non-assessable,  (ii) free from all taxes, liens
and charges with respect to the issue  thereof and (iii)  entitled to the rights

entitled  to all  rights  accorded  to a holder of Common  Stock.  Assuming  the
representation  and warranties of the Buyers contained in Section 2 are true and
correct,  the  issuance  by  the  Company  of  the  Securities  is  exempt  from
registration under the 1933 Act.

                  e. No  Conflicts.  Except as disclosed in Schedule  3(e),  the
execution, delivery and performance of the Transaction Documents by the Company,
the  performance  by the Company of its  obligations  under the  Certificate  of
Amendment and the consummation by the Company of the  transactions  contemplated
hereby and thereby (including,  without limitation, the reservation for issuance
and  issuance  of the  Conversion  Shares and the Warrant  Shares)  will not (i)
result in a violation of the  Certificate of  Incorporation,  any Certificate of
Amendment,  Preferences and Rights of any outstanding  series of preferred stock
of the Company or the By-laws;  (ii) conflict  with, or constitute a default (or
an event  which  with  notice or lapse of time or both  would  become a default)
under, or give to others any rights of termination,  amendment,  acceleration or
cancellation of, any agreement,  indenture or instrument to which the Company or
any of its  Subsidiaries  is a party; or (iii) result in a violation of any law,
rule,  regulation,  order,  judgment  or  decree  (including  federal  and state

<PAGE>

securities  laws and  regulations and the rules and regulations of any principal
market or exchange on which the Common Stock is traded or listed)  applicable to
the Company or any of its  Subsidiaries or by which any property or asset of the
Company or any of its Subsidiaries is bound or affected.  Except as disclosed in
Schedule 3(e),  neither the Company nor its  Subsidiaries is in violation of any
term of (i) its Certificate of Incorporation or By-laws or their  organizational
charter  or  by-laws,  respectively,  or (ii) any  statute,  rule or  regulation
applicable  to the Company or its  Subsidiaries  and neither the Company nor its
Subsidiaries   is  in  default   under  any   contract,   agreement,   mortgage,
indebtedness,  indenture,  instrument,  judgment,  decree or order, except where
such violation would not either individually or in the aggregate have a Material
Adverse  Effect.  The business of the Company and its  Subsidiaries is not being
conducted,  and shall not be  conducted,  in violation of any law,  ordinance or
regulation of any  governmental  entity,  except where such violation  would not
either  individually or in the aggregate have a Material Adverse Effect.  Except
as  specifically  contemplated  by this  Agreement  and except such as have been
obtained  as of the date  hereof,  the  Company  is not  required  to obtain any
consent, authorization or order of, or make any filing or registration with, any
court or  governmental  agency or any  regulatory or  self-regulatory  agency in
order for it to  execute,  deliver or perform  any of its  obligations  under or
contemplated  by the  Transaction  Documents or the  Certificate of Amendment in
accordance  with the terms  hereof or thereof.  Except as  disclosed in Schedule
3(e), all consents, authorizations,  orders, filings and registrations which the
Company is  required  to obtain  pursuant to the  preceding  sentence  have been
obtained  or  effected  on or prior  to the date  hereof.  The  Company  and its
Subsidiaries are unaware of any facts or circumstances which might reasonably be
expected to give rise to any of the foregoing.  The Company complies with and is
not  in  violation  of  the  listing  requirements  of  or  shall  maintain  the
requirements  to be accepted  for trading on, as the case may be, the  Principal
Market (as  defined  below) as in effect on the date  hereof and on the  Closing
Date and has no actual  knowledge  of any facts which would  reasonably  lead to
delisting,  suspension  or the  rejection for trading of the Common Stock by the
Principal Market in the foreseeable future. For purposes of this Agreement,  the
"Principal  Market" means the securities or trading market upon which the Common
Stock is listed,  quoted or  reported  provided  that such  market is one of the
following:  the Over the  Counter  Bulletin  Board  (the  "OTCBB"),  the  Nasdaq
National Market, The Nasdaq SmallCap Market, NYSE or AMEX.

                  f. SEC Documents;  Financial Statements. Since March 31, 1998,
the Company has timely filed all reports, schedules, forms, statements and other
documents  required  to be filed by it with the SEC  pursuant  to the  reporting
requirements  of the 1934 Act,  (all of the  foregoing  filed  prior to the date
hereof and all exhibits included therein and financial  statements and schedules
thereto and  documents  incorporated  by  reference  therein  being  hereinafter
referred  to as the "SEC  Documents").  A  complete  list of the  Company's  SEC
Documents is set forth on the EDGAR database.  As of their respective dates, the
SEC Documents  complied in all material  respects with the  requirements  of the
1934  Act and the  rules  and  regulations  of the  SEC  promulgated  thereunder
applicable to the SEC Documents, and none of the SEC Documents, at the time they
were filed with the SEC,  contained  any untrue

<PAGE>

statement of a material  fact or omitted to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the  circumstances  under  which they were  made,  not  misleading.  As of their
respective  dates,  the financial  statements of the Company included in the SEC
Documents  complied  as  to  form  in  all  material  respects  with  applicable
accounting  requirements  of  the  SEC  with  respect  thereto.  Such  financial
statements have been prepared in accordance with generally  accepted  accounting
principles, consistently applied, during the periods involved (except (i) as may
be otherwise  indicated in such financial  statements or the notes  thereto,  or
(ii) in the case of unaudited interim statements, to the extent they may exclude
footnotes or may be condensed or summary  statements)  and fairly present in all
material respects the financial  position of the Company as of the dates thereof
and the  results of its  operations  and cash flows for the  periods  then ended
(subject,  in the  case  of  unaudited  statements,  to  normal  year-end  audit
adjustments).  Neither the Company nor any of its  Subsidiaries  or any of their
officers,  directors,  employees  or agents  have  provided  the Buyers with any
material,  nonpublic  information.  If  the  Common  Stock  was  designated  for
quotation on the Nasdaq SmallCap Market, the Company would meet the requirements
for the use of  Form  S-3 for  registration  of the  resale  of the  Registrable
Securities (as defined in the Registration Rights Agreement) by each Buyer.

                  g. Absence of Certain Changes. Except as disclosed in Schedule
3(g),  since  March 31, 1999 there has been no  material  adverse  change and no
material adverse development in the business, properties,  operations, financial
condition,   liabilities  or  results  of  operations  of  the  Company  or  its
Subsidiaries,  taken as a whole.  The Company has not taken any steps,  and does
not  currently  expect to take any steps,  to seek  protection  pursuant  to any
bankruptcy  law  nor  does  the  Company  or any of its  Subsidiaries  have  any
knowledge  that  its  creditors  intend  to  initiate   involuntary   bankruptcy
proceedings or any knowledge of any fact which would  reasonably lead a creditor
to do so.

                  h.  Absence of  Litigation.  Except as  disclosed  in Schedule
3(h), there is no action, suit,  proceeding,  inquiry or investigation before or
by any court, public board, government agency,  self-regulatory  organization or
body  pending or, to the  knowledge  of the Company or any of its  Subsidiaries,
threatened  against or  affecting  the  Company,  the Common Stock or any of the
Company's  Subsidiaries  or any of the Company's or the Company's  Subsidiaries'
officers or directors in their capacities as such, except as expressly set forth
in Schedule 3(h).  Except as set forth in Schedule 3(h), to the knowledge of the
Company none of the  directors or officers of the Company have been  involved in
securities related litigation during the past five years.

                  i. Acknowledgment  Regarding the Buyer's Purchase of Preferred
Shares.  The Company  acknowledges  and agrees that each of the Buyers is acting
solely in the capacity of arm's length purchaser with respect to the Transaction
Documents and the  Certificate  of Amendment and the  transactions  contemplated
thereby.  The  Company  further  acknowledges  that  Buyer  is not  acting  as a
financial  advisor or fiduciary of the Company (or in any similar capacity) with
respect to the

<PAGE>

Transaction  Documents and the  Certificate  of Amendment  and the  transactions
contemplated  thereby and any advice  given by any of the Buyers or any of their
respective   representatives  or  agents  in  connection  with  the  Transaction
Documents and the  Certificate  of Amendment and the  transactions  contemplated
thereby is merely  incidental to such Buyer's  purchase of the  Securities.  The
Company  further  represents to each Buyer that the Company's  decision to enter
into  the  Transaction  Documents  has  been  based  solely  on the  independent
evaluation by the Company and its representatives.

                  j.  No  Undisclosed  Events,   Liabilities,   Developments  or
Circumstances.  Except for the  issuance of the  Preferred  Shares and  Warrants
contemplated by this Agreement, no event, liability, development or circumstance
has occurred or exists with respect to the Company or its  Subsidiaries or their
respective business,  properties,  operations or financial condition, that would
be required to be disclosed by the Company under applicable securities laws on a
registration  statement  (including by way of  incorporation by reference) filed
with the SEC relating to an issuance and sale by the Company of its Common Stock
and which has not been publicly disclosed.

                  k. No General  Solicitation.  Neither the Company,  nor any of
its affiliates, nor any person acting on its or their behalf, has engaged in any
form of general  solicitation  or general  advertising  (within  the  meaning of
Regulation  D under  the 1933 Act) in  connection  with the offer or sale of the
Securities.

                  l. No Integrated Offering. Neither the Company, nor any of its
affiliates,  nor any  person  acting on its or their  behalf  has,  directly  or
indirectly,  made any offers or sales of any security or solicited any offers to
buy any security,  under  circumstances  that would require  registration of the
issuance of any of the  Securities  under the 1933 Act or cause this offering of
Securities to be integrated  with prior offerings by the Company for purposes of
the 1933  Act or any  applicable  stockholder  approval  provisions,  including,
without  limitation,  under the rules and  regulations  of the  Nasdaq  SmallCap
Market, nor will the Company or any of its Subsidiaries take any action or steps
that would require  registration  of the Securities  under the 1933 Act or cause
the offering of the Securities to be integrated with other offerings.

                  m.  Employee  Relations.  Neither  the  Company nor any of its
Subsidiaries is involved in any union labor dispute nor, to the knowledge of the
Company or any of its Subsidiaries,  is any such dispute threatened. None of the
Company's or its Subsidiaries' employees is a member of a union which relates to
their  relationship  with  the  Company,  neither  the  Company  nor  any of its
Subsidiaries is a party to a collective  bargaining  agreement,  and the Company
and its Subsidiaries believe that their relations with their employees are good.
No  executive  officer (as defined in Rule 501(f) of the 1933 Act) has  notified
the Company's  Board of Directors that such officer intends to leave the Company
or otherwise terminate such officer's employment with the Company.

<PAGE>

                  n.   Intellectual   Property  Rights.   The  Company  and  its
Subsidiaries  own or possess  adequate rights or licenses to use all trademarks,
trade names, service marks, service mark registrations,  service names, patents,
patent  rights,  copyrights,   inventions,  licenses,  approvals,   governmental
authorizations,  trade secrets and rights  necessary to conduct their respective
businesses  as now  conducted,  except where such failure  would not have either
individually or in the aggregate a Material Adverse Effect.  Except as set forth
on Schedule 3(n), none of the Company's trademarks,  trade names, service marks,
service mark registrations,  service names, patents, patent rights,  copyrights,
inventions,  licenses,  approvals,  government authorizations,  trade secrets or
other intellectual  property rights have expired or terminated,  or are expected
to expire or terminate within two years from the date of this Agreement,  except
where such  expiration or termination  would not have either  individually or in
the aggregate a Material Adverse Effect. The Company and its Subsidiaries do not
have any knowledge of any  infringement  by the Company or its  Subsidiaries  of
trademarks,  trade name rights, patents, patent rights, copyrights,  inventions,
licenses,  service  names,  service  marks,  service mark  registrations,  trade
secrets or other similar rights of others, or of any such development of similar
or identical trade secrets or technical information by others and, except as set
forth on Schedule 3(n), no claim,  action or proceeding has been made or brought
against, or to the Company's knowledge, has been threatened against, the Company
or its Subsidiaries  regarding trademarks,  trade name rights,  patents,  patent
rights, inventions,  copyrights, licenses, service names, service marks, service
mark registrations, trade secrets or other infringement; and the Company and its
Subsidiaries are unaware of any facts or circumstances  which might give rise to
any of the foregoing.  The Company and its  Subsidiaries  have taken  reasonable
security  measures to protect the secrecy,  confidentiality  and value of all of
their intellectual properties.

                  o.  Regulatory  Permits.  The  Company  and  its  Subsidiaries
possess all certificates,  authorizations  and permits issued by the appropriate
federal,  state or foreign  regulatory  authorities  necessary to conduct  their
respective  businesses,  and neither the Company nor any Subsidiary has received
any notice of proceedings relating to the revocation or modification of any such
certificate, authorization or permit.

                  p. Internal Accounting  Controls.  The Company and each of its
Subsidiaries  maintain a system of internal  accounting  controls  sufficient to
provide  reasonable  assurance that (i)  transactions are executed in accordance
with  management's  general or specific  authorizations,  (ii)  transactions are
recorded  as  necessary  to  permit  preparation  of  financial   statements  in
conformity with generally accepted  accounting  principles and to maintain asset
accountability,  (iii) access to assets is  permitted  only in  accordance  with
management's   general  or  specific   authorization   and  (iv)  the   recorded
accountability  for assets is compared  with the existing  assets at  reasonable
intervals and appropriate action is taken with respect to any differences.

                  q. Tax Status.  The Company and each of its  Subsidiaries  has
made

<PAGE>

or filed all federal  and state  income and all other tax  returns,  reports and
declarations  required by any  jurisdiction  to which it is subject  (unless and
only to the extent that the Company and each of its  Subsidiaries  has set aside
on its books  provisions  reasonably  adequate for the payment of all unpaid and
unreported taxes) and has paid all taxes and other governmental  assessments and
charges  that are  material  in amount,  shown or  determined  to be due on such
returns,  reports and  declarations,  except those being contested in good faith
and for  which the  Company  has set  aside on its  books  provision  reasonably
adequate for the payment of all taxes for periods  subsequent  to the periods to
which such returns,  reports or declarations apply. There are no unpaid taxes in
any  material  amount  claimed  to  be  due  by  the  taxing  authority  of  any
jurisdiction,  and the  officers  of the  Company  know of no basis for any such
claim.

                  r.  Transactions  With  Affiliates.  Except  as set  forth  on
Schedule 3(r) and in the SEC Documents filed at least ten days prior to the date
hereof and other than the grant of stock  options  disclosed  on Schedule  3(c),
none of the  officers,  directors,  or  employees  of the Company is presently a
party to any transaction with the Company or any of its Subsidiaries (other than
for services as  employees,  officers and  directors),  including  any contract,
agreement or other  arrangement  providing for the  furnishing of services to or
by,  providing for rental of real or personal  property to or from, or otherwise
requiring payments to or from any officer,  director or such employee or, to the
knowledge of the Company, any corporation, partnership, trust or other entity in
which any officer,  director, or any such employee has a substantial interest or
is an officer, director, trustee or partner.

                  s. Dilutive Effect.  The Company  understands and acknowledges
that the number of Conversion  Shares  issuable upon conversion of the Preferred
Shares will increase in certain circumstances.  The Company further acknowledges
that its obligation to issue Conversion  Shares upon conversion of the Preferred
Shares in accordance  with this  Agreement and the  Certificate of Amendment and
its obligation to issue the Warrant Shares in accordance with this Agreement and
the Warrants  is, in each case,  absolute and  unconditional  regardless  of the
dilutive effect that such issuance may have on the ownership  interests of other
stockholders of the Company.

                  t.  Application of Takeover  Protections.  The Company and its
board of directors have taken all necessary  action,  if any, in order to render
inapplicable any control share acquisition,  business  combination,  poison pill
(including  any  distribution   under  a  rights  agreement)  or  other  similar
anti-takeover  provision under the Certificate of  Incorporation  or the laws of
the state of its incorporation which is or could become applicable to the Buyers
as a result of the Buyers and the Company fulfilling their obligations under the
Transaction  Documents  and the  Certificate  of Amendment,  including,  without
limitation,  the Company's  issuance of the Securities and the Buyers' ownership
of the Securities.

                  u. Rights  Agreement.  As of the date hereof,  the Company has
not  adopted a  shareholder  rights  plan or  similar  arrangement  relating  to
accumulation  of

<PAGE>

beneficial ownership of Common Stock or a change in control of the Company.

                  v. Year 2000  Compliance.  The Company has  initiated a review
and  assessment  of all areas  within  its and each  Subsidiary's  business  and
operations  that  could be  materially  adversely  affected  by the  "Year  2000
Problem"  (that is, the risk that computer  applications  used by the Company or
any  of the  Subsidiaries  may be  unable  to  recognize  and  perform  properly
date-sensitive  functions  involving  certain  dates prior to and any date after
December  31,  1999).  Based on the  foregoing,  the Company  believes  that the
computer  applications  that are currently  material to its or any  Subsidiary's
business and operations are reasonably  expected to be able to perform  properly
data-sensitive functions for all dates before and after January 1, 2000.

                  w.  Environmental  Laws. The Company and its  Subsidiaries (i)
are in compliance in all material respects with any and all applicable  foreign,
federal,  state and local laws and  regulations  relating to the  protection  of
human health and safety,  the  environment  or hazardous or toxic  substances or
wastes,  pollutants or contaminants ), (ii) have received all permits,  licenses
or other  approvals  required  of them under  applicable  Environmental  Laws to
conduct their respective businesses and (iii) are in com-pliance in all material
respects with all terms and conditions of any such permit, license or approval.

                  x.  Title.  The  Company  and its  Subsidiaries  have good and
marketable  title in fee  simple to all real  property  and good and  marketable
title to all personal  property  owned by them which is material to the business
of the Company and its  Subsidiaries,  in each case free and clear of all liens,
encumbrances  and defects  except such as are described in Schedule 3(p) or such
as do not materially affect the value of such property and do not interfere with
the use made and proposed to be made of such  property by the Company and any of
its  Subsidiaries.  Any real  property  and  facilities  held under lease by the
Company and any of its Subsidiaries are held by them under valid, subsisting and
enforceable leases with such exceptions as are not material and do not interfere
with the use made and proposed to be made of such  property and buildings by the
Company and its Subsidiaries.

                  y.  Insurance.  The Company and each of its  Subsidiaries  are
insured by insurers of recognized financial  responsibility  against such losses
and risks and in such  amounts  as  management  of the  Company  believes  to be
customary  in the  businesses  in which the  Company  and its  Subsidiaries  are
engaged.  Neither  the Company nor any such  Subsidiaries  has been  refused any
insurance  coverage  sought or applied  for and neither the Company nor any such
Subsidiaries  has any  reason to  believe  that it will not be able to renew its
existing  insurance  coverage  as and when such  coverage  expires  or to obtain
similar  coverage  from  similar  insurers as may be  necessary  to continue its
business at a cost that would not materially and adversely affect the condition,
financial or otherwise,  or the earnings,  business or operations of the Company
and its Subsidiaries, taken as a whole.

<PAGE>

                  z. No Other  Agreements.  The  Company  has not,  directly  or
indirectly,  made  any  agreements  with  any  Buyer  relating  to the  terms or
conditions of the transactions  contemplated by the Transaction Documents except
as set forth in the Transaction Documents.

                  aa. Foreign Corrupt Practices. Neither the Company, nor any of
its Subsidiaries,  nor any director,  officer,  agent,  employee or other person
acting on behalf of the Company or any of its Subsidiaries has, in the course of
its actions for, or on behalf of, the Company,  used any corporate funds for any
unlawful contribution,  gift,  entertainment or other unlawful expenses relating
to  political  activity;  made any direct or  indirect  unlawful  payment to any
foreign or  domestic  government  official  or employee  from  corporate  funds;
violated  or is in  violation  of any  provision  of the  U.S.  Foreign  Corrupt
Practices Act of 1977, as amended; or made any unlawful bribe,  rebate,  payoff,
influence payment, kickback or other unlawful payment to any foreign or domestic
government official or employee.

         4.       COVENANTS.

                  a. Best Efforts.  Each party shall use its best efforts timely
to satisfy each of the  conditions to be satisfied by it as provided in Sections
6 and 7 of this Agreement.

                  b. Form D and Blue Sky.  The  Company  agrees to file a Form D
with respect to the Securities as required  under  Regulation D and to provide a
copy thereof to each Buyer promptly after such filing.  The Company shall, on or
before the  applicable  Closing  Date,  take such  action as the  Company  shall
reasonably  determine  is  necessary  to qualify the  Securities  for, or obtain
exemption for the Securities for, sale to the Buyers at the Closing  pursuant to
this Agreement under  applicable  securities or "Blue Sky" laws of the states of
the United States, and shall provide evidence of any such action so taken to the
Buyers on or prior to the Closing  Date.  The Company shall make all filings and
reports  relating  to the  offer  and  sale  of the  Securities  required  under
applicable  securities  or "Blue Sky" laws of the  states of the  United  States
following the Closing Date.

                  c. Reporting Status.  Until the later of (i) the date which is
one year after the date on which the  Investors  (as that term is defined in the
Registration  Rights  Agreement) may sell all of the  Conversion  Shares and the
Warrant Shares without restriction pursuant to Rule 144(k) promulgated under the
1933 Act (or  successor  thereto)  and (ii) the date on which (A) the  Investors
shall have sold all the Conversion Shares and the Warrant Shares and (B) none of
the Preferred  Shares or Warrants is outstanding (the "Reporting  Period"),  the
Company shall file all reports required to be filed with the SEC pursuant to the
1934 Act, and the Company shall not  terminate its status as an issuer  required
to file  reports  under  the 1934 Act  even if the  1934  Act or the  rules  and
regulations thereunder would otherwise permit such termination.

                  d. Use of Proceeds. The Company will use the proceeds from the

<PAGE>

sale  of the  Preferred  Shares  for  substantially  the  same  purposes  and in
substantially the same amounts as indicated in Schedule 4(d).

                  e.  Financial  Information.  The  Company  agrees  to send the
following to each  Investor (as defined in the  Registration  Rights  Agreement)
during the Reporting  Period:  (i) within two (2) days after the filing  thereof
with the SEC, a copy of its  Annual  Reports  on Form 10-K or Form  10-KSB,  its
Quarterly  Reports on Form 10-Q or Form 10-QSB,  any Current Reports on Form 8-K
and any  registration  statements  (other than on Form S-8) or amendments  filed
pursuant to the 1933 Act;  and (ii) copies of any notices and other  information
made  available  or  given  to  the  stockholders  of  the  Company   generally,
contemporaneously   with  the  making   available  or  giving   thereof  to  the
stockholders.

                  f.  Reservation  of Shares.  The Company shall take all action
necessary  to at all times have  authorized,  and  reserved  for the  purpose of
issuance,  no less than the sum of (A) 200% the number of shares of Common Stock
needed to provide  for the  issuance of the  Conversion  Shares and (B) 100% the
number of shares of Common  Stock  needed to  provide  for the  issuance  of the
Warrant  Shares  (without  regard to any  limitations on conversions or exercise
thereof).

                  g. Right of Participation. Subject to the exceptions described
below,  during  the  period  beginning  on the date  hereof  and  ending on, and
including,  the date which is one year after the date the Registration Statement
registering  the  Registrable  Securities  is declared  effective by the SEC the
Company and its Subsidiaries  shall not negotiate or contract with any party for
any equity financing  (including any debt financing with an equity component) or
issue any equity  securities  of the  Company or any  Subsidiary  or  securities
convertible  into or  exchangeable  for equity  securities of the Company or any
Subsidiary  (including  debt  securities  with an equity  component) in any form
("Future  Offerings"),  unless it shall have first  delivered to each Buyer or a
designee  appointed by such Buyer written notice (the "Future Offering  Notice")
describing  the  proposed  Future  Offering,   including  the  size,  terms  and
conditions  thereof,  and  providing  each Buyer an option to purchase up to its
Aggregate  Percentage  (as defined below) of the securities to be issued in such
Future Offering,  as of the date of delivery of the Future Offering  Notice,  in
the  Future  Offering  (the  limitations   referred  to  in  this  sentence  are
collectively referred to as the "Capital Raising Limitations").  For purposes of
this Section 4(g), "Aggregate  Percentage" at any time with respect to any Buyer
shall mean the percentage  obtained by multiplying  (I) 50% by (II) the quotient
of (i) the aggregate  number of the Preferred Shares issued to such Buyer on the
Closing Date by (ii) the aggregate  number of the Preferred Shares issued to all
the Buyers on the Closing  Date. A Buyer can exercise its option to  participate
in a Future Offering by delivering  written notice thereof to participate to the
Company  within  three (3)  business  days after  receipt  of a Future  Offering
Notice, which notice shall state the quantity of securities being offered in the
Future Offering that such Buyer will purchase,  up to its Aggregate  Percentage,
and that  number  of  securities  it is  willing  to  purchase  in excess of its
Aggregate  Percentage.  In the event  that one or more  Buyers  fail to elect to
purchase up to each such Buyer's  Aggregate

<PAGE>

Percentage of the Future  Offering,  then each Buyer which has indicated that it
is willing to purchase a number of securities in such Future  Offering in excess
of its  Aggregate  Percentage  shall be  entitled to purchase up to its pro rata
portion  (determined in the same manner as described in the preceding  sentence)
of the  securities in the Future  Offering  which one or more of the Buyers have
not  elected  to  purchase.  In the  event  the  Buyers  fail to  elect to fully
participate in the Future Offering within the periods  described in this Section
4(g),  the Company shall have 45 days  thereafter to sell the  securities of the
Future  Offering  that the  Buyers  did not elect to  purchase,  upon  terms and
conditions,  no more favorable to the  purchasers  thereof than specified in the
Future Offering Notice. In the event the Company has not sold such securities of
the Future Offering within such 45 day period,  the Company shall not thereafter
issue or sell such  securities  without first  offering  such  securities to the
Buyers  in the  manner  provided  in this  Section  4(g).  The  Capital  Raising
Limitations  shall  not  apply to (i) a loan from a  commercial  bank,  (ii) the
Company's   issuances  of  securities  (A)  as  consideration  in  a  merger  or
consolidation, (B) in connection with any strategic partnership or joint venture
(the  primary  purpose  of  which  is not to  raise  equity  capital)  or (C) as
consideration  for the  acquisition  of a  business,  product,  license or other
assets by the Company,  (iii) the issuance of Common Stock in a firm commitment,
underwritten  public offering,  (iv) the issuance of securities upon exercise or
conversion of the Company's  options,  warrants or other convertible  securities
outstanding as of the date hereof  provided the terms of such securities are not
amended after the date hereof,  (v) the grant of additional options or warrants,
or the issuance of additional  securities,  under any Company stock option plan,
restricted  stock plan or stock  purchase  plan for the benefit of the Company's
employees,  officers or  directors  for services  provided to the  Company.  The
Buyers  shall not be required to  participate  or exercise  their right of first
refusal with respect to a particular  Future Offering in order to exercise their
right of first refusal with respect to later Future Offerings.

                  h. Listing.  The Company shall promptly  secure the listing of
all of the  Registrable  Securities  (as  defined  in  the  Registration  Rights
Agreement)  upon each  national  securities  exchange  and  automated  quotation
system,  if any,  upon which shares of Common Stock are then listed  (subject to
official notice of issuance) and shall maintain,  so long as any other shares of
Common Stock shall be so listed, such listing of all Registrable Securities from
time to time  issuable  under the  terms of the  Transaction  Documents  and the
Certificate  of  Amendment.  The  Company  shall  maintain  the  Common  Stock's
authorization  for listing,  quotation  or  reporting  on the OTCBB,  The Nasdaq
SmallCap Market,  the Nasdaq National Market,  AMEX or NYSE. Neither the Company
nor any of its  Subsidiaries  shall  take any  action  which  may  result in the
discontinuance of quotation or reporting of the Common Stock on the OTCBB (other
than to switch listings from the OTCBB to The Nasdaq SmallCap Market, the Nasdaq
National  Market,  AMEX or NYSE).  The Company shall  promptly,  and in no event
later than the following  business day, offer to provide to such Buyer copies of
any notices it receives from The Nasdaq  SmallCap  Market,  the Nasdaq  National
Market, AMEX or NYSE regarding the continued eligibility of the Common Stock for
listing on such automated quotation system or securities exchange, provided that
such

<PAGE>

notices shall not contain any material non-public information. The Company shall
pay all fees and expenses in connection with  satisfying its  obligations  under
this Section 4(h).

                  i.  Expenses.  Subject to Section  9(l) below,  at the Initial
Closing, the Company shall pay a non-accountable expense allowance of $45,000 to
the Buyers or their designees.

                  j. Transactions With Affiliates.  So long as (i) any Preferred
Shares or Warrants are outstanding or (ii) any Buyer owns  Conversion  Shares or
Warrant  Shares with a market value of $500,000 the Company shall not, and shall
cause each of its Subsidiaries not to, enter into, amend,  modify or supplement,
or permit  any  Subsidiary  to enter  into,  amend,  modify or  supplement,  any
agreement,  transaction,  commitment  or  arrangement  with  any  of  its or any
Subsidiary's officers,  directors,  person who were officers or directors at any
time during the previous two years, stockholders who beneficially own 5% or more
of the Common  Stock,  or affiliates  or with any  individual  related by blood,
marriage or adoption to any such individual or with any entity in which any such
entity or  individual  owns a 5% or more  beneficial  interest  (each a "Related
Party"),  except for (a) customary employment  arrangements and benefit programs
on reasonable terms, (b) any agreement,  transaction,  commitment or arrangement
which is approved by a majority of the disinterested directors of the Company or
(c) any  agreement,  transaction,  commitment or  arrangement  on an arms-length
basis on terms no less  favorable  than terms which  would have been  obtainable
from a person other than such Related Party. For purposes  hereof,  any director
who is also an officer of the Company or any Subsidiary of the Company shall not
be a  disinterested  director with respect to any such  agreement,  transaction,
commitment or arrangement.  "Affiliate" for purposes hereof means,  with respect
to any person or entity,  another person or entity that, directly or indirectly,
(i) has a 5% or more equity  interest  in that person or entity,  (ii) has 5% or
more common ownership with that person or entity,  (iii) controls that person or
entity,  or (iv) shares common control with that person or entity.  "Control" or
"controls"  for  purposes  hereof  means  that a person or entity has the power,
direct or  indirect,  to  conduct or govern the  policies  of another  person or
entity.

                  k.  Filing of Form 8-K.  On or before the third  business  day
following the Initial Closing Dates and the first business day following each of
the Mandatory  Share Notice Date,  the Mandatory  Closing Date,  the  Additional
Share Notice Dates and the  Additional  Closing  Dates the Company  shall file a
Form 8-K with the SEC describing the terms of the  transaction  contemplated  by
the Transaction  Documents and consummated at such Closing,  in each case in the
form required by the 1934 Act.

                  l. Proxy Statement. The Company shall provide each shareholder
entitled  to vote at the next  meeting of  shareholders  of the  Company,  which
meeting  shall occur on or before  January 31,  1999 (the  "Shareholder  Meeting
Deadline"), a proxy statement,  which has been previously reviewed by the Buyers
and a counsel of their choice,  soliciting each such  shareholder's  affirmative
vote at such shareholder

<PAGE>

meeting for  approval of the  Company's  issuance  of all of the  Securities  as
described  in this  Agreement,  and the  Company  shall use its best  efforts to
solicit its shareholders'  approval of such issuance of the Securities and cause
the Board of Directors of the Company to recommend to the shareholders that they
approve  such  proposal.  If  the  Company  fails  to  hold  a  meeting  of  its
shareholders by the Shareholder Meeting Deadline, then, as partial relief (which
remedy  shall not be  exclusive  of any other  remedies  available  at law or in
equity),  the Company shall pay to each holder of Preferred  Shares an amount in
cash per Preferred Share equal to the product of (i) $1,000;  multiplied by (ii)
0.02;  multiplied  by (iii) the  quotient  of (x) the  number of days  after the
Shareholder Meeting Deadline that a meeting of the Company's shareholders is not
held,  divided by (y) 30. The Company shall make the payments referred to in the
immediately  preceding  sentence  within five (5) days of the earlier of (I) the
holding  of the  meeting of the  Company's  shareholders,  the  failure of which
resulted in the requirement to make such payments, and (II) the last day of each
30-day period beginning on the Shareholder  Meeting  Deadline.  In the event the
Company fails to make such payments in a timely manner, such payments shall bear
interest  at lower of the rate of 2.0% per month or the maximum  rate  allowable
under New York law (pro rated for partial months) until paid in full.

                  m. Corporate Existence. So long as any Buyer beneficially owns
any  Preferred  Shares or Warrants,  the Company  shall  maintain its  corporate
existence and shall not sell all or substantially  all of the Company's  assets,
except in the event of a merger or consolidation or sale of all or substantially
all of the Company's  assets,  where the  surviving or successor  entity in such
transaction  (i)  assumes  the  Company's  obligations  hereunder  and under the
agreements  and  instruments  entered into in connection  herewith and (ii) is a
publicly  traded  corporation  whose  common  stock is listed for trading on The
Nasdaq SmallCap Market, the Nasdaq National Market or NYSE.

                  n. Nasdaq Listing.  The Company shall use its best efforts to,
on or before the date which is 45 days  after the date of this  Agreement,  have
all the shares of Common Stock,  including the Conversion Shares and the Warrant
Shares listed on the NYSE,  the Nasdaq  National  Market or The Nasdaq  SmallCap
Market.

         5.       TRANSFER AGENT INSTRUCTIONS.

                  The  Company  shall  issue  irrevocable  instructions  to  its
transfer  agent,  and any  subsequent  transfer  agent,  to issue  certificates,
registered  in the name of each  Buyer  or its  respective  nominee(s),  for the
Conversion  Shares and the Warrant Shares in such amounts as specified from time
to time by each Buyer to the Company upon conversion of the Preferred  Shares or
exercise  of the  Warrants  (in the  form  attached  hereto  as  Exhibit  E, the
"Irrevocable  Transfer  Agent  Instructions").  Prior  to  registration  of  the
Conversion  Shares  and  the  Warrant  Shares  under  the  1933  Act,  all  such
certificates shall bear the restrictive legend specified in Section 2(g) of this
Agreement.  The Company warrants that no instruction  other than the Irrevocable
Transfer  Agent  Instructions  referred to in this Section 5, and stop  transfer
instructions

<PAGE>

to give effect to Section 2(f) hereof (in the case of the Conversion  Shares and
the Warrant  Shares,  prior to  registration  of the  Conversion  Shares and the
Warrant  Shares under the 1933 Act) will be given by the Company to its transfer
agent and that the  Securities  shall  otherwise be freely  transferable  on the
books and records of the Company as and to the extent provided in this Agreement
and the Registration Rights Agreement. Nothing in this Section 5 shall affect in
any way each Buyer's  obligations  and  agreements  set forth in Section 2(g) to
comply with all applicable prospectus delivery requirements, if any, upon resale
of the  Securities.  If a Buyer provides the Company with an opinion of counsel,
in a form reasonably  satisfactory to the Company, that registration of a resale
by such Buyer of any of such  Securities  is not required  under the 1933 Act or
such Buyer provides the Company with  reasonable  assurances that the Securities
can be sold pursuant to Rule 144, the Company shall permit the transfer, and, in
the case of the Conversion Shares and the Warrant Shares,  promptly instruct its
transfer  agent  to  issue  one or more  certificates  in such  name and in such
denominations  as specified by such Buyer and without any  restrictive  legends.
The Company  acknowledges that a breach by it of its obligations  hereunder will
cause  irreparable harm to the Buyers by vitiating the intent and purpose of the
transaction contemplated hereby. Accordingly,  the Company acknowledges that the
remedy  at law for a breach  of its  obligations  under  this  Section 5 will be
inadequate  and  agrees,  in the event of a breach or  threatened  breach by the
Company of the  provisions of this Section 5, that the Buyers shall be entitled,
in addition to all other available  remedies,  to an injunction  restraining any
breach and requiring  immediate issuance and transfer,  without the necessity of
showing economic loss and without any bond or other security being required.

         6.       CONDITIONS TO THE COMPANY'S OBLIGATION TO SELL.

                  a.  Initial  Closing  Date.  The  obligation  of  the  Company

         satisfied and complied with the  covenants,  agreements  and conditions
         required by the  Transaction  Documents to be  performed,  satisfied or

         jurisdiction   which   prohibits  the   consummation   of  any  of  the
         transactions contemplated by this Agreement.

                  b.  Mandatory  Closing  Date.  The  obligation  of the Company
hereunder to issue and sell the  Mandatory  Preferred  Shares and the  Mandatory
Warrants to each Buyer at the Mandatory  Closing is subject to the satisfaction,
at or before the Mandatory  Closing  Date, of each of the following  conditions,
provided that these  conditions  are for the  Company's  sole benefit and may be
waived by the Company at any time in its sole discretion by providing each Buyer
with prior written notice thereof:

         Mandatory  Warrants  being  purchased  by such  Buyer at the  Mandatory

         and warranties that speak as of a specific date),  and such Buyer shall

         and conditions  required by the Transaction  Documents to be performed,

         Closing Date. The Company shall have received a  certificate,  executed
         by an  authorized  signatory  for such  Buyer,  dated as of the Initial
         Closing Date, to the foregoing effect.

         7.       CONDITIONS TO EACH BUYER'S OBLIGATION TO PURCHASE.

                  a.  Initial   Closing  Date.  The  obligation  of  each  Buyer
hereunder to purchase the Initial  Preferred  Shares and the Initial Warrants at

         certified by such  Secretary of State shall have been delivered to such
         Buyer.

                  (iii) The Common Stock shall be  designated  for  quotation on

         shall  delisting  or  suspension  by such  exchanges  or  quotation  or
         reporting  systems have been  threatened  either (A) in writing by such

indemnify and hold  harmless each Buyer and each other holder of the  Securities
and all of their  shareholders,  officers,  directors,  employees  and direct or
indirect   investors  and  any  of  the  foregoing   person's  agents  or  other
representatives  (including,  without  limitation,  those retained in connection
with  the  transactions  contemplated  by  this  Agreement)  (collectively,  the
"Indemnitees")  from and against any and all actions,  causes of action,  suits,
claims, losses, costs, penalties, fees, liabilities and damages, and expenses in
connection therewith  (irrespective of whether any such Indemnitee is a party to
the  action  for which  indemnification  hereunder  is  sought),  and  including
reasonable  attorneys' fees and disbursements  (the "Indemnified  Liabilities"),
incurred by any Indemnitee as a result of, or arising out of, or relating to (a)
any  misrepresentation  or breach of any  representation or warranty made by the
Company in the  Transaction  Documents  or the  Certificate  of Amendment or any
other certificate,  instrument or document  contemplated hereby or thereby,  (b)

Company  and  (y) not a  shareholder  derivative  suit)  and  arising  out of or
resulting (i) from the  execution,  delivery,  performance or enforcement of the
Transaction Documents or the Certificate of Amendment, (ii) from any transaction
financed or to be financed in whole or in part, directly or indirectly, with the
proceeds of the  issuance of the  Securities  or (iii) solely from the status of
such Buyer or holder of the  Securities  as an investor in the  Company.  To the
extent that the foregoing  undertaking by the Company may be  unenforceable  for
any reason,  the Company shall make the maximum  contribution to the payment and
satisfaction of each of the Indemnified  Liabilities  which is permissible under
applicable law.

         9.       GOVERNING LAW; MISCELLANEOUS .

                  a. Governing Law; Jurisdiction; Jury Trial. The corporate laws
of the State of New York shall govern all issues  concerning the relative rights
of the  Company  and  its  shareholders.  All  other  questions  concerning  the
construction,  validity,  enforcement and interpretation of this Agreement shall
be governed by the internal laws of the State of New York, without giving effect
to any choice of law or conflict of law  provision or rule (whether of the State
of New York or any other  jurisdictions) that would cause the application of the
laws of any  jurisdictions  other than the State of New York.  Each party hereby
irrevocably  submits to the non-exclusive

<PAGE>

jurisdiction  of the state and federal  courts  sitting in the City of New York,
borough  of  Manhattan  for the  adjudication  of any  dispute  hereunder  or in
connection  herewith or with any  transaction  contemplated  hereby or discussed
herein,  and hereby  irrevocably  waives,  and agrees not to assert in any suit,
action  or  proceeding,  any  claim  that it is not  personally  subject  to the
jurisdiction of any such court,  that such suit, action or proceeding is brought
in an inconvenient forum or that the venue of such suit, action or proceeding is
improper.  Each party hereby  irrevocably waives personal service of process and
consents  to process  being  served in any such suit,  action or  proceeding  by
mailing a copy thereof to such party at the address for such notices to it under
this Agreement and agrees that such service shall constitute good and sufficient
service of process and notice thereof.  Nothing contained herein shall be deemed
to limit in any way any right to serve  process in any manner  permitted by law.
EACH PARTY HEREBY  IRREVOCABLY  WAIVES ANY RIGHT IT MAY HAVE,  AND AGREES NOT TO
REQUEST,  A JURY  TRIAL FOR THE  ADJUDICATION  OF ANY  DISPUTE  HEREUNDER  OR IN
CONNECTION  HEREWITH  OR  ARISING  OUT OF  THIS  AGREEMENT  OR  ANY  TRANSACTION
CONTEMPLATED HEREBY.

                  b. Counterparts. This Agreement may be executed in two or more
identical  counterparts,  all of  which  shall  be  considered  one and the same
agreement and shall become effective when  counterparts have been signed by each
party and  delivered to the other  party;  provided  that a facsimile  signature
shall be  considered  due  execution  and shall be  binding  upon the  signatory
thereto with the same force and effect as if the signature were an original, not
a facsimile signature.

                  c.   Headings.   The  headings  of  this   Agreement  are  for
convenience   of   reference   and  shall  not  form  part  of,  or  affect  the
interpretation of, this Agreement.

                  d.  Severability.  If any provision of this Agreement shall be
invalid   or   unenforceable   in   any   jurisdiction,   such   invalidity   or
unenforceability  shall  not  affect  the  validity  or  enforceability  of  the
remainder  of  this   Agreement  in  that   jurisdiction   or  the  validity  or
enforceability of any provision of this Agreement in any other jurisdiction.

                  e. Entire Agreement; Amendments. This Agreement supersedes all
other prior oral or written agreements  between the Buyers,  the Company,  their
affiliates  and  persons  acting on their  behalf  with  respect to the  matters
discussed  herein,  and this  Agreement and the  instruments  referenced  herein
contain  the entire  understanding  of the parties  with  respect to the matters
covered  herein and therein  and,  except as  specifically  set forth  herein or
therein,  neither the Company nor any Buyer makes any representation,  warranty,
covenant or  undertaking  with  respect to such  matters.  No  provision of this
Agreement may be amended  other than by an  instrument in writing  signed by the
Company and the Buyers which purchased at least  two-thirds (2/3) of the Initial
Preferred Shares on the Initial Closing Date or, if prior to the Initial Closing
Date, the Buyers listed on the Schedule of Buyers as being obligated to purchase
at least two-thirds (2/3) of the Initial Preferred Shares, then outstanding, and
no provision  hereof may be waived other than by an instrument in writing signed
by the party against whom  enforcement  is sought.  No such  amendment  shall be

<PAGE>

effective  to the extent  that it applies to less than all of the holders of the
Preferred Shares or Warrants then outstanding. No consideration shall be offered
or paid to any  person to amend or consent  to a waiver or  modification  of any
provision of any of the  Transaction  Documents or the  Certificate of Amendment
unless  the same  consideration  also is  offered  to all of the  parties to the
Transaction Documents or holders of the Preferred Shares, as the case may be.

                           g.       Successors and Assigns. This Agreement shall
be binding  upon and inure to the benefit of the  parties  and their  respective
successors and assigns,  including any purchasers of the Preferred  Shares.  The
Company shall not assign this Agreement or any rights or  obligations  hereunder
without  the prior  written  consent  of the  Buyers  which  purchased  at least
two-thirds  (2/3) of the Initial  Preferred  Shares on the Initial Closing Date,
including  by merger or  consolidation.  A Buyer may  assign  some or all of its
rights  hereunder to (i) a Permitted  Transferee  (as defined below) without the
consent of the Company and (ii) to a person which is not a Permitted  Transferee
with the prior consent of the Company,  which consent shall not be  unreasonably
withheld.  Notwithstanding anything to the contrary contained in the Transaction
Documents,  the Buyers shall be entitled to pledge the  Securities in connection
with a bona fide margin  account or other loan secured by such  Securities.  For
purposes of this Section 9(g), a "Permitted  Transferee" shall mean (i) a Buyer,
(ii) an Affiliate (as that term is defined in Rule 501(b) under the 1933 act) of
a Buyer, (iii) any holder of Preferred Shares or Warrants and (iv) any Affiliate
of a holder of Preferred Shares or Warrants.

                           h.       No Third Party Beneficiaries. This Agreement
is intended for the benefit of the parties hereto and their respective permitted
successors  and  assigns,  and is not for the benefit of, nor may any  provision
hereof be enforced by, any other person.

                           i.       Survival.    Unless   this    Agreement   is
terminated under Section 9(l), the representations and warranties of the Company
and the Buyers  contained in Sections 2 and 3, the  agreements and covenants set
forth in Sections 4, 5 and 9, and the  indemnification  provisions  set forth in
Section 8, shall  survive  each of the  Closings,  provided,  however,  that the
representations  and  Warranties  of the  Company  and the Buyers  contained  in
Sections 2 and 3 shall  survive each of the Closings only until such time as the
Preferred  Shares and the  Warrants  issued at such  closing  or the  Conversion
Shares or the Warrant Shares issuable upon conversion or exercise  thereof,  are
no longer held by the Buyers.  Each Buyer shall be responsible  only for its own
representations, warranties, agreements and covenants hereunder.

                           j.       Publicity.  The Company and each Buyer shall
have the right to approve before issuance any press releases or any other public
statements  with  respect to the  transactions  contemplated  hereby;  provided,
however,  that the

<PAGE>

Company shall be entitled,  without the prior approval of the Buyer, to make any
press release or other public disclosure with respect to such transactions as is
required by applicable law and  regulations  (although the Company shall use its
reasonable  efforts to consult with each Buyer in connection with any such press
release or other public  disclosure prior to its release and each Buyer shall be
provided with a copy thereof).

                           k.       Further Assurances.  Each party shall do and
perform,  or cause to be done and  performed,  all such further acts and things,
and  shall  execute  and  deliver  all  such  other  agreements,   certificates,
instruments and documents, as the other party may reasonably request in order to
carry out the intent and  accomplish  the  purposes  of this  Agreement  and the
consummation of the transactions contemplated hereby.

                           l.       Termination.  In the event that the  Initial
Closing  shall not have  occurred with respect to a Buyer on or before three (3)
business days from the date hereof due to the  Company's or the Buyer's  failure
to  satisfy  the  conditions  set  forth  in  Sections  6 and 7 above  (and  the
non-breaching  party's  failure to waive  such  unsatisfied  condition(s)),  the
non-breaching  party  shall have the option to  terminate  this  Agreement  with
respect to such  breaching  party at the close of business on such date  without
liability  of any  party to any other  party;  provided,  however,  that if this
Agreement is terminated  pursuant to this Section 9(l), the Company shall remain
obligated  to  reimburse  a  non-breaching  Buyer for  expenses up to the amount
described in Section 4(i) above.

                           m.       Placement  Agent.  The Company  acknowledges
that  it has  engaged  Zanett  Securities  Corporation  as  placement  agent  in
connection with the sale of the Preferred Shares and the related  Warrants.  The
Company shall be  responsible  for the payment of any placement  agent's fees or
brokers' commissions relating to or arising out of the transactions contemplated
hereby.  The  Company  shall pay,  and hold each  Buyer  harmless  against,  any
liability, loss or expense (including, without limitation, reasonable attorneys'
fees and out of pocket expenses) arising in connection with any such claim.

                           n.       No Strict Construction. The language used in
this  Agreement  will be deemed to be the  language  chosen  by the  parties  to
express their mutual intent, and no rules of strict construction will be applied
against any party.

                           o.       Remedies.  Each Buyer and each holder of the
Securities  shall  have all  rights and  remedies  set forth in the  Transaction
Documents and the  Certificate  of Amendment  and all rights and remedies  which
such holders have been granted at any time under any other agreement or contract
and all of the rights which such  holders have under any law. Any person  having
any rights under any  provision of this  Agreement  shall be entitled to enforce
such rights specifically (without posting a bond or other security),  to recover
damages  by  reason of any  breach of any  provision  of this  Agreement  and to
exercise all other rights granted by law.

<PAGE>


                           p.       Payment  Set Aside.  To the extent  that the
Company  makes a payment or payments to any Buyer  hereunder  or pursuant to the
Registration  Rights Agreement,  the Certificate of Amendment or the Warrants or
such Buyer enforces or exercises its rights  hereunder or  thereunder,  and such
payment or payments or the proceeds of such  enforcement or exercise or any part
thereof are subsequently invalidated, declared to be fraudulent or preferential,
set aside,  recovered from, disgorged by or are required to be refunded,  repaid
or otherwise  restored to the Company,  a trustee,  receiver or any other person
under any law  (including,  without  limitation,  any  bankruptcy  law, state or
federal law, common law or equitable cause of action), then to the extent of any
such  restoration  the  obligation  or part  thereof  originally  intended to be
satisfied  shall be revived  and  continued  in full force and effect as if such
payment had not been made or such enforcement or setoff had not occurred.

PART A.  Series A Preferred Stock.

      Eight Hundred Five (805) of the Ten Million (10,000,000) authorized shares
of  Preferred  Stock of the  Company  are hereby  designated  Series A Preferred
Stock,  par value $.05 per share.

<PAGE>

(References to section numbers in this Part A of Article FOURTH shall refer only
to such sections in this Part A of Article FOURTH,  unless  otherwise  expressly
stated  herein.)  The Series A  Preferred  Stock  shall  possess  the rights and
preferences set forth below:

      Section 1. Designation and Amount.  The shares of such series shall have a
par value of $.05 per share and shall be designated as Series A Preferred  Stock
(the  "Series A  Preferred  Stock")  and the number of shares  constituting  the
Series A  Preferred  Stock  shall be Eight  Hundred  Five  (805).  The  Series A
Preferred  Stock shall be offered at a purchase  price of Ten  Thousand  Dollars
($10,000.00) per share (the "Original Series A Issue Price"), with a ten percent
(10%) per annum accretion rate as set forth herein.

      Section 2. Rank.  The Series A Preferred  Stock shall rank:  (i) junior to
any other  class or series of capital  stock of the  Company  hereafter  created
specifically  ranking  by its  terms  senior  to the  Series A  Preferred  Stock
(collectively,  the  "Senior  Securities");  (ii) prior to all of the  Company's
Common  Stock,  $.01 par value per share  ("Common  Stock");  (iii) prior to any
class  or  series  of  capital  stock  of  the  Company  hereafter  created  not
specifically  ranking  by its terms  senior to or on  parity  with any  Series A
Preferred Stock of whatever  subdivision  (collectively,  with the Common Stock,
"Junior  Securities");  and (iv) on parity  with any class or series of  capital
stock of the  Company  hereafter  created  specifically  ranking by its terms on
parity with the Series A Preferred  Stock ("Parity  Securities") in each case as
to  distributions of assets upon  liquidation,  dissolution or winding up of the
Company, whether voluntary or involuntary (all such distributions being referred
to collectively as "Distributions").

      Section 3. Dividends. The Series A Preferred Stock will bear no dividends,
and the  holders  of the  Series A  Preferred  Stock  ("Holders")  shall  not be
entitled to receive dividends on the Series A Preferred Stock.

      Section 4. Liquidation Preference.

      (a) In the event of any  liquidation,  dissolution  or  winding  up of the
Company,  either  voluntary  or  involuntary,  the Holders of shares of Series A
Preferred   Stock  shall  be  entitled   to  receive,   immediately   after  any
distributions  to Senior  Securities  required by the Company's  Certificate  of
Incorporation or any certificate of designation,  and prior in preference to any
distribution to Junior  Securities but in parity with any distribution to Parity
Securities,  an amount per share equal to the sum of (i) the  Original  Series A
Issue Price for each  outstanding  share of Series A Preferred Stock and (ii) an
amount equal to ten percent (10%) of the Original Series A Issue Price per annum
for the period  that has  passed  since the date that,  in  connection  with the
consummation  of the  purchase by Holder of shares of Series A  Preferred  Stock
from  the  Company,   the  escrow  agent  first  had  in  its  possession  funds
representing  full  payment  for the shares of Series A  Preferred  Stock  (such
amount being  referred to herein as the  "Premium").  If upon the  occurrence of
such event, and after payment in full of the  preferential  amounts with respect
to the Senior Securities,

<PAGE>

the assets and funds available to be distributed among the Holders of the Series
A Preferred  Stock and Parity  Securities  shall be  insufficient  to permit the
payment to such Holders of the full  preferential  amounts due to the Holders of
the Series A Preferred Stock and the Parity Securities,  respectively,  then the
entire assets and funds of the Company legally available for distribution  shall
be distributed  among the Holders of the Series A Preferred Stock and the Parity
Securities,  pro rata, based on the respective liquidation amounts to which each
such series of stock is entitled by the Company's  Certificate of  Incorporation
and any certificate(s) of designation relating thereto.

      (b) Upon the completion of the  distribution  required by subsection 4(a),
if assets remain in this Company, they shall be distributed to holders of Junior
Securities  in  accordance  with  the  Company's  Certificate  of  Incorporation
including any duly adopted certificate(s) of designation.

      (c) At each Holder's option,  a sale,  conveyance or disposition of all or
substantially  all of the  assets  of the  Company  or the  effectuation  by the
Company of a transaction  or series of related  transactions  in which more than
fifty  percent  (50%) of the voting power of the Company is disposed of shall be
deemed to be a liquidation, dissolution or winding up within the meaning of this
Section 4; provided further that an event described in the prior clause that the
Holder does not elect to treat as a  liquidation  and a  consolidation,  merger,
acquisition, or other business combination of the Company with or into any other
company  or  companies  shall not be treated as a  liquidation,  dissolution  or
winding up within the meaning of this  Section 4, but  instead  shall be treated
pursuant to Section 5(e) hereof.

      (d) In the event that,  immediately  prior to the closing of a transaction
described in Section 4(c) which would  constitute a liquidation  event, the cash
distributions  required  by Section  4(a) or  Section 6 have not been made,  the
Company  shall  either:  (i) cause such closing to be postponed  until such cash
distributions  have been made, or (ii) cancel such  transaction,  in which event
the  rights of the  Holders  of Series A  Preferred  Stock  shall be the same as
existing immediately prior to such proposed transaction.

      Section 5. Conversion. The record Holders of this Series A Preferred Stock
shall have conversion rights as follows (the "Conversion Rights"):

      (a) Right to Convert. Each record Holder of Series A Preferred Stock shall
be entitled (at the times and in the amounts set forth below) and subject to the
Company's  right of  redemption  set forth in Section 6(a), at the office of the
Company or any transfer  agent for the Series A Preferred  Stock (the  "Transfer
Agent"),  to  convert  (in  multiples  of one (1) share of  Preferred  Stock) as
follows:  (x) up to  one-third  (1/3) of the shares of Series A Preferred  Stock
initially  issued to such  Holder  at any time  beginning  forty-five  (45) days
following  the date of the  last  closing  of a  purchase  and sale of  Series A
Preferred  Stock that occurs  pursuant to the offering of the Series A Preferred
Stock by the Company (the "Last Closing

<PAGE>

Date") and at any time  thereafter,  (y) up to an additional  one-third (1/3) of
the shares of Series A Preferred  Stock  initially  issued to such Holder at any
time beginning seventy-five (75) days following the Last Closing Date and at any
time  thereafter,  and (z) all remaining  Series A Preferred  Stock held by such
Holder at any time  beginning  one hundred  five (105) days  following  the Last
Closing Date (each of the time periods referenced in subclauses (x), (y) and (z)
is hereinafter  referred to singularly as a "Conversion  Gate") at the office of
the Company or any Transfer  Agent for the Series A Preferred  Stock,  into that
number of fully-paid  and  non-assessable  shares of Common Stock of the Company
calculated in accordance with the following formula (the "Conversion Rate"):

         Number of shares  issued upon  conversion  of one (1) share of Series A
Preferred Stock =

                         (.10) (N/365) (10,000) + 10,000
                         -------------------------------
                                Conversion Price

where,

      N= the number of days between (i) the date that,  in  connection  with the
consummation  of the initial  purchase by Holder of shares of Series A Preferred
Stock from the  Company,  the escrow  agent  first had in its  possession  funds
representing  full payment for the shares of Series A Preferred  Stock for which
conversion is being  elected,  and (ii) the  applicable  Date of Conversion  (as
defined in Section  5(c)(iv)  below) for the shares of Series A Preferred  Stock
for which conversion is being elected, and

      Conversion  Price = the  lesser  of (x) 100% of the  average  Closing  Bid
Price,  as that term is defined  below,  for the five (5) trading days ending on
June 28,  1996 (the  "Fixed  Conversion  Price"),  or (y) .85 times the  average
Closing Bid Price, as that term is defined below, of the Company's  Common Stock
for the five (5) trading days immediately  preceding the Date of Conversion,  as
defined below (the "Variable Conversion Price").

      For purposes  hereof,  the term "Closing Bid Price" shall mean the closing
bid price on the OTC Electronic  Bulletin Board, or if no longer traded thereon,
on the Nasdaq Small Cap Market or the Nasdaq National  Market,  or if not traded
on the Nasdaq Small Cap Market or the Nasdaq  National  Market,  the closing bid
price on the principal national  securities  exchange or the automatic quotation
system on which the Common Stock is so traded and if not available, the price of
the last sale on the  principal  national  securities  exchange or the automatic
quotation system on which the Common Stock is so traded.

      (b) Mechanics of Conversion.  In order to convert Series A Preferred Stock
into full shares of Common Stock, the Holder shall (i) fax, on or prior to 11:59
p.m.,  New York City  time (the  "Conversion  Notice  Deadline")  on the date of
conversion,  a copy of the fully  executed  notice  of  conversion  ("Notice  of
Conversion")  to the  Company  at the office of the  Company  or its  designated
Transfer  Agent for the Series A Preferred  Stock stating that the Holder elects
to convert,  which notice shall  specify the date of  conversion,  the number of
shares of Series A

<PAGE>

Preferred  Stock  to  be  converted,  the  applicable  conversion  price  and  a
calculation  of the  number  of  shares  of  Common  Stock  issuable  upon  such
conversion  (together  with a copy of the front page of each  certificate  to be
converted) and (ii) surrender to a common courier, for delivery to the office of
the Company or the Transfer Agent,  the original  certificates  representing the
Series A Preferred Stock being converted (the "Preferred  Stock  Certificates"),
duly endorsed for  transfer;  provided,  however,  that the Company shall not be
obligated to issue  certificates  evidencing the shares of Common Stock issuable
upon  such  conversion  unless  either  the  Preferred  Stock  Certificates  are
delivered to the Company or its Transfer Agent as provided  above, or the Holder
notifies  the Company or its  Transfer  Agent that such  certificates  have been
lost,  stolen or destroyed  (subject to the  requirements  of  subparagraph  (i)
below).  Upon receipt by Company of a facsimile  copy of a Notice of Conversion,
Company shall immediately send, via facsimile,  a confirmation of receipt of the
Notice of Conversion to Holder which shall specify that the Notice of Conversion
has been received and the name and telephone  number of a contact  person at the
Company whom the Holder  should  contact  regarding  information  related to the
Conversion.  In the case of a dispute as to the  calculation  of the  Conversion
Rate,  the Company shall  promptly issue to the Holder the number of Shares that
are not  disputed  and shall  submit the  disputed  calculations  to its outside
accountant via facsimile  within three (3) days of receipt of Holder's Notice of
Conversion.  The Company shall cause the accountant to perform the  calculations
and notify  Company  and Holder of the  results no later than  forty-eight  (48)
hours  from  the  time  it  receives  the  disputed  calculations.  Accountant's
calculation shall be deemed conclusive absent manifest error.

            (i) Lost or Stolen  Certificates.  Upon  receipt  by the  Company of
evidence of the loss,  theft,  destruction or mutilation of any Preferred  Stock
Certificates  representing  shares of Series A Preferred Stock, and (in the case
of loss, theft or destruction) of indemnity or security reasonably  satisfactory
to the Company,  and upon  surrender and  cancellation  of the  Preferred  Stock
Certificate(s),  if  mutilated,  the  Company  shall  execute  and  deliver  new
Preferred Stock  Certificate(s) of like tenor and date.  However,  Company shall
not be obligated to re-issue such lost or stolen Preferred Stock Certificates if
Holder  contemporaneously  requests  Company to convert  such Series A Preferred
Stock into Common Stock.

            (ii) Delivery of Common Stock Upon Conversion. The Transfer Agent or
the Company (as  applicable)  shall,  no later than the close of business on the
second  (2nd)  business  day (the  "Deadline")  after  receipt by the Company or
Transfer  Agent of a  facsimile  copy of a Notice of  Conversion  and receipt by
Company or the Transfer Agent of all necessary  documentation  duly executed and
in proper form required for conversion,  including the original  Preferred Stock
Certificates to be converted (or after provision for security or indemnification
in the case of lost or destroyed certificates, if required), issue and surrender
to a common  courier for either  overnight or (if delivery is outside the United
States)  two (2)  day  delivery  (or  the  shortest  period  of time in  which a
recognized  international  courier can  deliver) to the Holder at the address of
the Holder as shown on the stock records of the Company a certificate for

<PAGE>

the number of shares of Common  Stock to which the Holder  shall be  entitled as
aforesaid.

            (iii)  No  Fractional  Shares.  If any  conversion  of the  Series A
Preferred  Stock would create a  fractional  share of Common Stock or a right to
acquire a  fractional  share of Common  Stock,  such  fractional  share shall be
disregarded  and the number of shares of Common Stock issuable upon  conversion,
in the aggregate, shall be the next lower number of shares.

            (iv) Date of Conversion.  The date on which  conversion  occurs (the
"Date of Conversion") shall be deemed to be the date set forth in such Notice of
Conversion,  provided (i) that the advance copy of the Notice of  Conversion  is
faxed to the  Company  before  11:59  p.m.,  New York City time,  on the Date of
Conversion, and (ii) that the original Preferred Stock Certificates representing
the  shares of Series A  Preferred  Stock to be  converted  are  surrendered  by
depositing  such  certificates  with a common courier,  as provided  above,  and
received by the Transfer Agent or the Company as soon as  practicable  after the
date set forth in the Notice of  Conversion.  The person or persons  entitled to
receive  the  shares of Common  Stock  issuable  upon such  conversion  shall be
treated  for all  purposes  as the record  Holder or  Holders of such  shares of
Common  Stock  on the  Date  of  Conversion.  If the  original  Preferred  Stock
Certificates  representing  the Series A Preferred Stock to be converted are not
received by the  Transfer  Agent or the Company  within ten (10)  business  days
after the Date of Conversion, or if the facsimile of the Notice of Conversion is
not  received  by the  Company or its  designated  Transfer  Agent  prior to the
Conversion Notice Deadline,  the Notice of Conversion,  at the Company's option,
may be declared null and void.

      (c)  Reservation of Stock Issuable Upon  Conversion.  The Company shall at
all times reserve and keep available out of its  authorized but unissued  shares
of Common  Stock,  solely for the purpose of  effecting  the  conversion  of the
Series A Preferred  Stock,  such  number of its shares of Common  Stock as shall
from time to time be sufficient to effect the conversion of all then outstanding
Series A Preferred  Stock.  If at any time the number of authorized but unissued
shares of Common Stock shall not be sufficient  to effect the  conversion of all
then outstanding  shares of Series A Preferred Stock, the Company will take such
corporate  action as may be necessary to increase  its  authorized  but unissued
shares of Common Stock to such number of shares as shall be sufficient  for such
purpose; provided,  however, that the taking of such action shall not affect the
Company's  liability,  if any, for damages arising as a result of its failure to
have a sufficient number of shares reserved.

      (d)  Automatic  Conversion.   Each  share  of  Series  A  Preferred  Stock
outstanding  on the date which is three (3) years  after the Last  Closing  Date
automatically  shall  be  converted  into  Common  Stock  on  such  date  at the
Conversion  Rate then in effect  (calculated  in accordance  with the formula in
Section  5(a)  above),  and the date  which is three  (3)  years  after the Last
Closing  Date  shall be  deemed  the Date of  Conversion  with  respect  to such
conversion.

      (e) Adjustment to Conversion Rate.

<PAGE>

            (i) Adjustment to Fixed Conversion  Price Due to Stock Split,  Stock
Dividend,  Etc.  If,  prior to the  conversion  of all of the Series A Preferred
Stock, the number of outstanding  shares of Common Stock is increased by a stock
split, stock dividend,  or other similar event, the Fixed Conversion Price shall
be  proportionately  reduced,  or if the number of outstanding  shares of Common
Stock is decreased by a  combination  or  reclassification  of shares,  or other
similar event, the Fixed Conversion Price shall be proportionately increased.

            (ii) Adjustment to Variable  Conversion  Price. If, at any time when
any shares of the Series A  Preferred  Stock are  issued  and  outstanding,  the
number of  outstanding  shares of Common  Stock is  increased  or decreased by a
stock split,  stock  dividend,  or other similar  event,  which event shall have
taken place during the  reference  period for  determination  of the  Conversion
Price for any  conversion  of the Series A Preferred  Stock,  then the  Variable
Conversion  Price shall be  calculated  giving  appropriate  effect to the stock
split, stock dividend, combination,  reclassification or other similar event for
all five (5) trading days immediately preceding the Date of Conversion.

            (iii) Adjustment Due to Merger, Consolidation, Etc. If, prior to the
conversion  of all  Series  A  Preferred  Stock,  there  shall  be  any  merger,
consolidation,  exchange of shares, recapitalization,  reorganization,  or other
similar event,  as a result of which shares of Common Stock of the Company shall
be changed into the same or a different  number of shares of the same or another
class or  classes of stock or  securities  of the  Company or another  entity or
there is a sale of all or  substantially  all the Company's assets or there is a
change of control transaction not deemed to be a liquidation pursuant to section
4(c),  then the Holders of Series A Preferred  Stock shall  thereafter  have the
right to receive upon conversion of Series A Preferred Stock, upon the basis and
upon the terms and  conditions  specified  herein  and in lieu of the  shares of
Common Stock  immediately  theretofore  issuable  upon  conversion,  such stock,
securities  and/or other  assets  which the Holder  would have been  entitled to
receive in such  transaction  had the Series A  Preferred  Stock been  converted
immediately  prior  to  such  transaction,  and in  any  such  case  appropriate
provisions shall be made with respect to the rights and interests of the Holders
of the  Series  A  Preferred  Stock  to  the  end  that  the  provisions  hereof
(including, without limitation,  provisions for the adjustment of the Conversion
Price and of the  number of shares  issuable  upon  conversion  of the  Series A
Preferred Stock) shall thereafter be applicable, as nearly as may be practicable
in relation to any securities  thereafter  deliverable upon the exercise hereof.
The  Company  shall not  effect any  transaction  described  in this  subsection
5(e)(iii) unless (a) it first uses its best efforts to give thirty (30) days and
in any event gives at least  twenty (20) days notice prior to the record date of
such   merger,    consolidation,    exchange   of   shares,    recapitalization,
reorganization,  or other  similar  event (during which time the Holder shall be
entitled to convert its shares of Series A  Preferred  Stock into Common  Stock)
and (b) the resulting successor or acquiring entity (if not the Company) assumes
by written  instrument the obligations of the Company

<PAGE>

under this Certificate of Designation including this subsection 5(e)(iii).

            (iv) No Fractional Shares. If any adjustment under this Section 5(e)
would  create a  fractional  share of  Common  Stock  or a right  to  acquire  a
fractional share of Common Stock, such fractional share shall be disregarded and
the number of shares of Common Stock issuable upon conversion  shall be the next
lower number of shares.

      Section 6. Redemption by Company.

      (a) Company's Right to Redeem Upon Receipt of Notice of Conversion. If the
Conversion Price of the Company's Common Stock is less than the Fixed Conversion
Price (as  defined  in  Section  5(a)),  at the time of  receipt  of a Notice of
Conversion  pursuant to Section 5, the Company shall have the right, in its sole
discretion, to redeem in whole or in part any Series A Preferred Stock submitted
for conversion, immediately prior to and in lieu of conversion ("Redemption Upon
Receipt of Notice of Conversion"). If the Company elects to redeem some, but not
all, of the Series A Preferred Stock submitted for conversion, the Company shall
redeem  from  among  the  Series A  Preferred  Stock  submitted  by the  various
shareholders  for conversion on the applicable date, a pro-rata amount from each
such Holder so submitting Series A Preferred Stock for conversion.

            (i)  Redemption  Price Upon Receipt of a Notice of  Conversion.  The
redemption  price per share of Series A Preferred  Stock under this Section 6(a)
shall be  calculated  in  accordance  with the  following  formula  ("Redemption
Rate"):

[[(.10)(N/365)(10,000)] + 10,000] x Closing Bid Price on Date of Conversion
                                    ---------------------------------------
                                              Conversion Price

where,

      "N",  "Date of  Conversion",  "Closing Bid Price" and  "Conversion  Price"
shall have the same meanings as defined in Section 5.

            (ii)  Mechanics of Redemption  Upon Receipt of Notice of Conversion.

The Company  shall effect each such  redemption by giving notice of its election
to redeem,  by facsimile,  by 5:00 p.m. New York City time the next business day
following receipt of a Notice of Conversion from a Holder, and the Company shall
provide a copy of such redemption notice by overnight or two (2) day courier, to
(A) the Holder of the Series A Preferred  Stock  submitted for conversion at the
address and facsimile number of such Holder appearing in the Company's  register
for the Series A Preferred  Stock and (B) the  Company's  Transfer  Agent.  Such
redemption  notice shall indicate whether the Company will redeem all or part of
the  Series A  Preferred  Stock  submitted  for  conversion  and the  applicable
redemption price.

      (b)  Company's  Right to Redeem at its Election.  At any time,  commencing
twelve  (12)  months and one (1) day after the Last  Closing  Date,  the Company
shall  have the  right,  in its  sole

<PAGE>

discretion,  to redeem ("Redemption at Company's Election"),  from time to time,
any or all of the Series A Preferred  Stock;  provided  (i) Company  shall first
provide  thirty (30) days  advance  written  notice as provided in  subparagraph
6(b)(ii) below (which can be given beginning  thirty (30) business days prior to
the date  which is twelve  (12)  months  and one (1) day after the Last  Closing
Date),  and (ii) that the  Company  shall only be  entitled  to redeem  Series A
Preferred Stock having an aggregate  Stated Value (as defined below) of at least
One Million Five Hundred Thousand Dollars ($1,500,000.00). If the Company elects
to redeem some, but not all, of the Series A Preferred  Stock, the Company shall
redeem a pro-rata amount from each Holder of the Series A Preferred Stock.

            (i) Redemption Price At Company's Election. The "Redemption Price At
Company's Election" shall be calculated as a percentage of Stated Value, as that
term is defined below, of the Series A Preferred Stock redeemed pursuant to this
Section 6(b), which percentage shall vary depending on the Date of Redemption at
Company's Election (as defined below), and shall be determined as follows:

Date of Notice of Redemption at Company's Election            % of Stated Value

12 months and 1 day to 18 months following Last Closing Date          130%
18 months and 1 day to 24 months following Last Closing Date          125%
24 months and 1 day to 30 months following Last Closing Date          120%
30 months and 1 day to 36 months following Last Closing Date          115%

      For purposes hereof, "Stated Value" shall mean the Original Series A Issue
Price (as  defined in Section  4(a)) of the shares of Series A  Preferred  Stock
being  redeemed  pursuant to this Section  6(b),  together  with the accrued but
unpaid Premium (as defined in Section 4(a)).

            (ii)  Mechanics of  Redemption  at Company's  Election.  The Company
shall  effect  each such  redemption  by giving at least  thirty (30) days prior
written notice ("Notice of Redemption At Company's Election") to (A) the Holders
of the Series A Preferred  Stock  selected  for  redemption,  at the address and
facsimile  number of such Holder  appearing in the Company's  Series A Preferred
stock  register  and (B) the  Transfer  Agent,  which  Notice of  Redemption  At
Company's  Election  shall be deemed to have been  delivered  three (3) business
days after the Company's  mailing (by  overnight or two (2) day courier,  with a
copy by  facsimile) of such Notice of  Redemption  At Company's  Election.  Such
Notice of  Redemption  At Company's  Election  shall  indicate (i) the number of
shares of Series A Preferred Stock that have been selected for redemption,  (ii)
the date which such  redemption is to become  effective (the "Date of Redemption
At Company's  Election") and (iii) the applicable  Redemption Price At Company's
Election,  as defined in  subsection  (b)(i) above.  Notwithstanding  the above,
Holder may convert into Common  Stock  pursuant to section 5, prior to the close
of  business  on the Date of  Redemption  at  Company's  Election,  any

<PAGE>

Series A Preferred  Stock which it is otherwise  entitled to convert,  including
Series A Preferred  Stock that has been  selected  for  redemption  at Company's
election pursuant to this subsection 6(b); provided,  however, that the Company,
shall still be entitled to exercise its right to redeem upon receipt of a Notice
of Conversion pursuant to Section 6(a).

      (c) Company Must Have  Immediately  Available Funds or Credit  Facilities.
The Company  shall not be entitled to send any  Redemption  Notice and begin the
redemption procedure under Sections 6(a) and 6(b) unless it has:

            (i) the full amount of the redemption price in cash,  available in a
demand or other  immediately  available  account in a bank or similar  financial
institution; or

            (ii) immediately available credit facilities,  in the full amount of
the redemption price with a bank or similar financial institution; or

            (iii) an agreement  with a standby  underwriter  willing to purchase
from the  Company a  sufficient  number of shares of stock to  provide  proceeds
necessary to redeem any stock that is not converted prior to redemption; or

            (iv) a  combination  of the items  set forth in (i),  (ii) and (iii)
above, aggregating the full amount of the redemption price.

      (d) Payment of Redemption Price.

            (i) Each Holder submitting Preferred Stock being redeemed under this
Section 6 shall send their  Preferred  Stock  Certificates  so  redeemed  to the
Company  or its  Transfer  Agent,  and the  Company  shall  pay  the  applicable
redemption  price to that Holder  within five (5)  business  days of the Date of
Redemption at Company's Election.  The Company shall not be obligated to deliver
the redemption  price unless the Preferred  Stock  Certificates  so redeemed are
delivered  to the Company or its  Transfer  Agent,  or, in the event one or more
certificates have been lost,  stolen,  mutilated or destroyed,  until the Holder
has complied with Section 5(c)(i).

            (ii) If Company elects to redeem  pursuant to either Section 6(a) or
6(b) hereof,  and Company  fails to pay Holder the  redemption  price within the
time frame as required by this Section 6(d),  then Company shall issue shares of
Common  Stock to any such  Holder who has  submitted a Notice of  Conversion  in
compliance with Section 5(c) hereof.  The shares to be issued to Holder pursuant
to this provision  shall be the number of shares  determined  using a Conversion
Price (as  defined  in  Section  6 hereof)  that  equals  the  lesser of (i) the
Conversion Price on the date Holder sends its Notice of Conversion to Company or
Transfer  Agent  via  facsimile,  or (ii) the  Conversion  Price on the date the
Transfer  Agent issues  Common  Stock  pursuant to this  Section  6(d)(ii).  The
issuance of such shares shall not affect the  Company's  liability to the Holder
for damages, if any, arising as a result of its failure to redeem.

      (e) Blackout Period. Notwithstanding the foregoing, the

<PAGE>

Company  may not  either  send out a  redemption  notice or effect a  redemption
pursuant to Section  6(b) above  during a Blackout  Period  (defined as a period
during which the Company's officers or directors would not be entitled to buy or
sell stock because of their holding of material non-public information),  unless
the Company shall first disclose the non-public information that resulted in the
Blackout Period;  provided,  however, that no redemption shall be effected until
at least ten (10) days after the  Company  shall  have given the Holder  written
notice that the Blackout Period has been lifted.

      Section 7. Advance Notice of Redemption.

      (a) Holder's  Right to Elect to Receive  Notice of Cash  Redemption by the
Company.  Holder  shall  have the right to require  Company  to provide  advance
notice  stating  whether the  Company  will elect to redeem  Holder's  shares of
Series A Preferred Stock in cash,  pursuant to the Company's  redemption  rights
discussed in Section 6(a).

      (b)  Mechanics  of  Holder's  Election  Notice.  Holder  shall send notice
("Election  Notice")  to the  Company  and such other  person as the Company may
designate,  via  facsimile,  stating  Holder's  intention to require  Company to
disclose  that if Holder were to exercise  his,  her or its right of  conversion
(pursuant to Section 5) whether  Company would elect to redeem a specific number
of shares  of  Holder's  Series A  Preferred  Stock for cash in lieu of  issuing
Common  Stock.  Company is required  to  disclose to Holder what action  Company
would take over the  subsequent  twenty (20) business day period,  including the
date of such Election Notice, as further discussed in subsection 7(c).

      (c) Company's Response. Upon receipt by the Company of a facsimile copy of
an  Election  Notice,   Company  shall  immediately   send,  via  facsimile,   a
confirmation  of receipt of the Election  Notice to Holder  which shall  specify
that the Election Notice has been received and the name and telephone  number of
a  contact  person at the  Company  whom the  Holder  should  contact  regarding
information  related to the requested  advance notice.  Thereafter  Company must
respond by the close of business on the next business day  following  receipt of
Holder's  Election  Notice (1) via facsimile and (2) by depositing such response
with an overnight  or two (2) day courier.  The  Company's  response  must state
whether it would  redeem the shares,  in whole or in part,  or allow  conversion
into shares of Common Stock without  redemption.  If Company does not respond to
Holder  within one (1) business day via  facsimile  and overnight or two (2) day
courier, Company shall be required to issue to Holder Common Stock upon Holder's
conversion  within the  subsequent  twenty (20)  business day period of Holder's
Election Notice.  However, if the Company's Common Stock price decreases so that
under the  Conversion  Rate  Company  would be  required  to issue  more than an
additional  ten percent (10%) of shares of Common Stock than Holder was entitled
to receive at the time Holder sent  Company its  Election  Notice,  then Company
shall no longer be bound to convert  Holder's  Preferred Stock into Common Stock
but may elect to redeem for cash pursuant to Section 6(a).

      Section 8. Voting  Rights.  The  Holders of the Series A  Preferred  Stock
shall have no voting power whatsoever,  except as otherwise  provided by the New
York  General  Corporation  Law  ("New

<PAGE>

York Law"),  and no Holder of Series A Preferred  Stock shall vote or  otherwise
participate  in any proceeding in which actions shall be taken by the Company or
the shareholders thereof or be entitled to notification as to any meeting of the
shareholders.

      Notwithstanding the above,  Company shall provide Holder with notification
of  any  meeting  of the  shareholders  regarding  any  major  corporate  events
affecting the Company.  In the event of any taking by the Company of a record of
its shareholders for the purpose of determining shareholders who are entitled to
receive  payment of any dividend or other  distribution,  any right to subscribe
for,  purchase  or  otherwise  acquire  any  share  of any  class  or any  other
securities  or  property   (including  by  way  of  merger,   consolidation   or
reorganization),  or  to  receive  any  other  right,  or  for  the  purpose  of
determining  shareholders  who  are  entitled  to vote in  connection  with  any
proposed sale, lease or conveyance of all or substantially  all of the assets of
the  Company,  or any  proposed  liquidation,  dissolution  or winding up of the
Company, the Company shall mail a notice to Holder, at least ten (10) days prior
to the record date specified therein, of the date on which any such record is to
be taken for the purpose of such dividend,  distribution,  right or other event,
and a brief  statement  regarding  the amount and  character  of such  dividend,
distribution, right or other event to the extent known at such time.

      To the  extent  that  under  New York Law the vote of the  Holders  of the
Series A Preferred Stock, voting separately as a class, is required to authorize
a given action of the Company, the affirmative vote or consent of the Holders of
at least a majority of the shares of the Series A Preferred Stock represented at
a duly held  meeting at which a quorum is  present  or by  written  consent of a
majority of the shares of Series A Preferred  Stock  (except as otherwise may be
required under New York Law) shall constitute the approval of such action by the
class.  To the  extent  that  under  New York Law the  Holders  of the  Series A
Preferred  Stock are entitled to vote on a matter with holders of Common  Stock,
voting  together as one (1) class,  each share of Series A Preferred Stock shall
be entitled  to a number of votes equal to the number of shares of Common  Stock
into which it is then  convertible  using the record date for the taking of such
vote of  stockholders  as the date on which the Conversion  Price is calculated.
Holders of the Series A Preferred  Stock also shall be entitled to notice of all
shareholder  meetings or written  consents  with  respect to which they would be
entitled  to vote,  which  notice  would be provided  pursuant to the  Company's
by-laws and applicable statutes.

      Section 9. Protective  Provision.  So long as shares of Series A Preferred
Stock are  outstanding,  the  Company  shall not  without  first  obtaining  the
approval  (by vote or  written  consent,  as  provided  by New York  Law) of the
Holders of at least seventy-five percent (75%) of the then outstanding shares of
Series A Preferred  Stock, and at least  seventy-five  percent (75%) of the then
outstanding Holders:

      (a) alter or change the rights,  preferences or privileges of the Series A
Preferred Stock or any Senior  Securities so as to affect adversely the Series A
Preferred Stock;  provided,  however, that no such change may be approved at any
time on or

<PAGE>

prior to the  fortieth  (40th) day  following  the Last Closing Date unless such
change is unanimously approved by all Holders;

      (b) create any new class or series of stock having a preference over or on
parity  with the Series A  Preferred  Stock with  respect to  Distributions  (as
defined in Section 2 above) or  increase  the size of the  authorized  number of
Series A Preferred; or

      (c) do any act or thing not authorized or contemplated by this Designation
which  would  result in  taxation  of the  holders  of  shares  of the  Series A
Preferred  Stock under  Section 305 of the  Internal  Revenue  Code of 1986,  as
amended (or any comparable  provision of the Internal  Revenue Code as hereafter
from time to time amended);

provided,  however,  that nothing in this  subsection  shall limit the Company's
right to issue (i) straight debt  securities or (ii) debt  securities  which are
convertible  into  restricted  Common Stock which is  resaleable  only after the
expiration of the Rule 144 holding period.

      In the event  Holders of at least  seventy-five  percent (75%) of the then
outstanding shares of Series A Preferred Stock and at least seventy-five percent
(75%) of the then  outstanding  Holders  agree to allow the  Company to alter or
change the rights, preferences or privileges of the shares of Series A Preferred
Stock,  pursuant to subsection (a) above, so as to affect the Series A Preferred
Stock,  then the Company  will  deliver  notice of such  approved  change to the
Holders of the Series A Preferred Stock that did not agree to such alteration or
change (the  "Dissenting  Holders") and Dissenting  Holders shall have the right
for a period of thirty (30)  business  days to convert  pursuant to the terms of
this Certificate of Designation as they exist prior to such alteration or change
(notwithstanding the forty-five (45) day, seventy-five (75) day, and one hundred
five (105) day  holding  requirements  set forth in  Section  5(a)  hereof),  or
continue to hold their  shares of Series A Preferred  Stock  provided,  however,
that the  Dissenting  Holders may not convert  anytime on or before the fortieth
(40th) day following the Last Closing Date.

      Section 10. Status of Redeemed or Converted Stock. In the event any shares
of Series A Preferred Stock shall be redeemed or converted pursuant to Section 6
or Section 5 hereof,  the shares so  converted  or redeemed  shall be  canceled,
shall  return to the status of  authorized  but unissued  Preferred  Stock of no
designated  series,  and  shall  not be  issuable  by the  Company  as  Series A
Preferred Stock.

      Section 11. Preference Rights. Nothing contained herein shall be construed
to prevent the Board of  Directors  of the Company  from issuing one (1) or more
series of Preferred Stock with dividend and/or liquidation preferences junior to
the dividend and liquidation preferences of the Series A Preferred Stock."

Part B.  Series B Preferred Stock.

      Eight  Thousand  and  Sixty  (8,060)  of  the  Ten  Million   (10,000,000)
authorized  shares of Preferred Stock of the

<PAGE>

Corporation are hereby  designated  Series B Preferred Stock, par value $.05 per
share.  (References  to section  numbers in this Part B of Article FOURTH of the
Certificate  of  Incorporation  ("Part B") shall refer only to such  sections in
this Part B of Article FOURTH,  unless  otherwise  expressly stated herein.) The
Series B Preferred  Stock shall  possess  the rights and  preferences  set forth
below:

      Section 1. Designations and Amounts.  The shares of such series shall have
a par  value of $.05 per share and  shall be  designated  as Series B  Preferred
Stock (the "Series B Preferred Stock") and the number of shares constituting the
Series B  Preferred  Stock  shall be Eight  Thousand  and Sixty  (8,060).  Three
Thousand  Two Hundred  Twenty-Five  (3,225)  shares of Series B Preferred  Stock
shall be further  designated  as Series B-1  Preferred  Stock (the  "Series  B-1
Preferred Stock"), and Four Thousand Eight Hundred Thirty-Five (4,835) shares of
Series B Preferred  Stock shall be further  designated  as Series B-2  Preferred
Stock (the "Series B-2 Preferred Stock").  The Series B Preferred Stock shall be
offered at a purchase price of One Thousand  Dollars  ($1,000.00) per share (the
"Original Series B Issue Price").

      Section 2. Rank.  The Series B Preferred  Stock shall rank:  (a) junior to
any other class or series of capital stock of the Corporation  hereafter created
specifically  ranking  by its  terms  senior  to the  Series B  Preferred  Stock
(collectively,  the "Senior Securities");  (b) prior to all of the Corporation's
Common Stock, $.01 par value per share ("Common Stock");  (c) prior to any class
or series of capital stock of the Corporation hereafter created not specifically
ranking by its terms senior to or on parity with any Series B Preferred Stock of
whatever subdivision (collectively, with the Common Stock, "Junior Securities");
and (d) on parity with the Series A  Preferred  Stock and any class or series of
capital stock of the Corporation  hereafter created  specifically ranking by its
terms on parity with the Series B Preferred Stock ("Parity  Securities") in each
case as to distributions of assets upon  liquidation,  dissolution or winding up
of the Corporation,  whether  voluntary or involuntary  (all such  distributions
being referred to  collectively  as  "Distributions")  and as to dividends.  The
Series B-1  Preferred  Stock and the Series B-2  Preferred  Stock  shall rank on
parity with each other as to Distributions and dividends.

      Section 3. Dividends .

      3.1  Cumulative  Dividends.  The holders of Series B Preferred  Stock (the
"Series B Holders") shall be entitled to receive, out of funds legally available
therefor,  cumulative  annual dividends at an annual rate per share equal to ten
percent  (10%) of the Original  Series B Issue  Price,  and such amount shall be
compounded annually such that if the dividend is not paid for any year, then the
unpaid  amount shall be added to the Original  Series B Issue Price for purposes
of calculating succeeding years' dividends.  Such dividends shall accrue on each
share of  Series B  Preferred  Stock  from day to day from the date of issue and
shall be cumulative  until paid upon  liquidation,  dissolution or winding up of
the  Corporation  within the meaning of Section 4 hereof or upon  redemption  as
provided in Section 6 hereof or

<PAGE>

until such share is converted into Common Stock as provided in Section 5 hereof,
and such dividends shall so accrue whether or not earned or declared and whether
or not there are  profits,  surplus or other  funds of the  Corporation  legally
available for the payment of dividends.  If such cumulative dividends in respect
of any prior or current annual  dividend period shall not have been declared and
paid, then the deficiency shall first be fully paid before any dividend or other
distribution  shall be paid or declared  and set apart with respect to any class
of the  Corporation's  capital stock, now or hereafter  outstanding,  other than
Distributions  required  to be made to  holders  of  Series  A  Preferred  Stock
pursuant to Part A of this Article  FOURTH of the  Corporation's  Certificate of
Incorporation  ("Part A"). Cumulative dividends with respect to shares of Series
B Preferred Stock which are accrued,  payable and/or in arrears shall be paid on
December 21 of each year  commencing on December 21, 1998 (December 21, 1998 and
each  December 21  thereafter  being  referred to herein as a "Dividend  Payment
Date"), to the extent assets are legally available  therefor and any amounts for
which assets are not legally  available  shall be paid  promptly  thereafter  as
assets become legally  available  therefor;  any partial payment will be made to
the Series B Holders pro rata in accordance  with their holdings of such shares.
On any Dividend Payment Date occurring prior to December 21, 2001, (a) dividends
on shares of Series B-1  Preferred  Stock may be paid  through  the  issuance of
additional  shares of Series B-1 Preferred  Stock and (b) dividends on shares of
Series B-2 Preferred Stock may be paid through the issuance of additional shares
of Series B-2 Preferred Stock, in each case at the rate of one-tenth of one such
share for every $100 of accrued and unpaid dividends.

      3.2  Participating  Dividends.  In the event the Corporation shall make or
issue,  or shall fix a record  date for the  determination  of holders of Common
Stock entitled to receive,  a dividend or other distribution with respect to the
Common Stock payable in (a) securities of the  Corporation  other than shares of
Common Stock or (b) assets,  then and in each such event the holders of Series B
Preferred  Stock  shall  receive,  in addition to and not in lieu of any and all
dividends  under  Section  3.1,  at the  same  time  such  dividend  is  paid or
distribution is made with respect to Common Stock, the number of such securities
or such other assets of the Corporation which they would have received had their
Series B Preferred Stock been converted into Common Stock  immediately  prior to
the record date for determining holders of Common Stock entitled to receive such
distribution.

      3.3 Reservation of Stock Issuable as Dividends.  The Corporation  shall at
all times reserve and keep available out of its  authorized but unissued  shares
of Series B-1  Preferred  Stock and Series B-2 Preferred  Stock,  solely for the
purpose of effecting the payment of dividends on the Series B Preferred Stock as
provided in Section 3.1, such number of shares of Series B-1 Preferred Stock and
Series B-2  Preferred  Stock as shall from time to time be  sufficient to effect
such payment on all  outstanding  shares of Series B Preferred  Stock. If at any
time the number of authorized but unissued  shares of Series B-1 Preferred Stock
or Series B-2 Preferred  Stock shall not be sufficient to effect such payment on
all outstanding  shares of Series B Preferred  Stock,  the Corporation will take
such

<PAGE>

corporate  action as may be necessary to increase  its  authorized  but unissued
shares of Series B-1  Preferred  Stock and Series  B-2  Preferred  Stock to such
number of shares as shall be  sufficient  for such purpose;  provided,  however,
that the taking of such action shall not affect the Corporation's  liability, if
any, for damages arising as a result of its failure to have a sufficient  number
of shares reserved.

      Section 4. Liquidation Preference.

            4.1 In the event of any  liquidation,  dissolution  or winding up of
the  Corporation,  either  voluntary  or  involuntary,  the holders of shares of
Series B Preferred  Stock shall be  entitled to receive,  immediately  after any
distributions to Senior Securities required by the Corporation's  Certificate of
Incorporation,  and prior in preference to any distribution to Junior Securities
but in parity with any  distribution to Parity  Securities,  an amount per share
equal to the sum of (a) the Original  Series B Issue Price for each  outstanding
share of Series B  Preferred  Stock and (b) an amount  equal to all  accrued and
unpaid dividends thereon, whether or not declared, since the date of issue up to
and  including  the date full payment  shall have been  tendered to the Series B
Holders  with   respect  to  such   liquidation,   dissolution   or  winding  up
(collectively,  the "Series B Liquidation Amount").  If, after the occurrence of
any such  liquidation,  dissolution  or  winding  up and  payment in full of the
preferential amounts with respect to the Senior Securities, the assets and funds
available to be  distributed  among the holders of the Series B Preferred  Stock
and  Parity  Securities  shall be  insufficient  to permit  the  payment to such
holders  of the full  preferential  amounts  due to the  holders of the Series B
Preferred Stock and the Parity Securities,  respectively, then the entire assets
and  funds  of the  Corporation  legally  available  for  distribution  shall be
distributed  among the  holders of the Series B  Preferred  Stock and the Parity
Securities,  pro rata, based on the respective liquidation amounts to which each
such  series  of  stock  is  entitled  by  the   Corporation's   Certificate  of
Incorporation.

            4.2 Upon the completion of the distribution required by Section 4.1,
if assets remain in the  Corporation,  they shall be  distributed  to holders of
Junior   Securities  in  accordance  with  the   Corporation's   Certificate  of
Incorporation.

            4.3 At each  Series  B  Holder's  election,  a sale,  conveyance  or
disposition of all or substantially  all of the assets of the Corporation or the
effectuation   by  the  Corporation  of  a  transaction  or  series  of  related
transactions  (other than a registered  public  offering by the  Corporation  of
shares of its Common Stock) in which more than fifty percent (50%) of the voting
power of the  Corporation  is disposed  of shall be deemed to be a  liquidation,
dissolution or winding up within the meaning of this Section 4;  provided,  that
no such  election  by any Series B Holder in respect of any such event  shall be
effective so long as any shares of the  Corporation's  Series A Preferred  Stock
are outstanding  unless one or more holders of such outstanding shares of Series
A Preferred Stock exercise the  corresponding  option  available to such holders
under Section 4(c) of Part A in respect of such event. An event described in the
immediately  preceding  sentence  that a Series B Holder  does

<PAGE>

not elect or, by virtue of the proviso in such  sentence,  is unable to elect to
treat  as a  liquidation  and a  consolidation,  merger,  acquisition  or  other
business  combination  of the  Corporation  with or into any  other  company  or
companies  shall not be  treated  as a  liquidation,  dissolution  or winding up
within the meaning of this Section 4, but instead  shall be treated  pursuant to
Section 5.6 hereof.

            4.4 In the  event  that,  immediately  prior  to  the  closing  of a
transaction described in Section 4.3 which would constitute a liquidation event,
the cash distributions  required by Section 4.1 or Section 6 have not been made,
the Corporation shall either:  (a) cause such closing to be postponed until such
cash  distributions  have been made,  or (b) cancel such  transaction,  in which
event  the  rights  of the  Series  B  Holders  shall  be the  same as  existing
immediately prior to such proposed transaction.

      Section 5. Conversion.  The Series B Holders shall have conversion  rights
as follows (the "Conversion Rights"):

            5.1 Right to Convert. Each holder of any share of Series B Preferred
Stock shall be entitled,  subject to the  Corporation's  right of redemption set
forth in Section 6.1, at the office of the Corporation or any transfer agent for
the Series B Preferred  Stock (the "Transfer  Agent"),  to convert such share of
Series B Preferred  Stock, at any time after the first  anniversary of the first
issuance and sale by the Corporation of any shares of Series B Preferred  Stock,
into that number of fully-paid and non-assessable  shares of Common Stock of the
Corporation calculated in accordance with the following formula (the "Conversion
Rate"):

      Number of shares issued upon conversion of any share of Series B Preferred
Stock =

                                   1,000 + N
                                ------------------
                           Applicable Conversion Price

where,

      N = the amount of all unpaid  dividends  accrued from the date of issuance
to the applicable Date of Conversion (as defined in Section 5.3.5 below) of such
share of Series B Preferred Stock, and

      Applicable Conversion Price = the Series B Conversion Price (as defined in
Section 5.2) applicable to such share of Series B Preferred Stock.

      5.2 Conversion Price.

      5.2.1  Series B  Conversion  Price.  As used  herein,  the term  "Series B
Conversion  Price"  shall  mean  (a) in the  case of any  share  of  Series  B-1
Preferred  Stock,  the Series B-1 Conversion  Price,  as that term is defined in
Section  5.2.2 and (b) in the case of any share of Series B-2  Preferred  Stock,
the Series B-2 Conversion Price, as that term is defined in Section 5.2.3.

            5.2.2 Series B-1 Conversion Price. As used herein,  the term

<PAGE>

"Series B-1 Conversion Price" shall initially mean an amount equal to the lesser
of (a) $7.50 (the "Reference Price") or (b) .85 times the average Closing Price,
as that term is defined in Section 5.2.4, of the Corporation's  Common Stock for
the five trading days immediately  preceding the Date of Conversion,  as defined
in Section 5.3.5 (the "Variable Series B-1 Conversion Price"),  which Series B-1
Conversion  Price shall be adjusted,  however,  from time to time in  accordance
with this Section 5.

            5.2.3 Series B-2 Conversion Price. As used herein,  the term "Series
B-2 Conversion Price" shall initially mean an amount equal to the greater of (a)
the Reference  Price or (b) .85 times the average Closing Price, as that term is
defined in Section 5.2.4, of the Corporation's Common Stock for the five trading
days immediately preceding the date of the Corporation's first issuance and sale
of any shares of Series B Preferred  Stock,  which Series B-2  Conversion  Price
shall be adjusted, however, from time to time in accordance with this Section 5.

            5.2.4  Closing  Price.  The  term  "Closing  Price,"  as  used  with
reference to shares of Common Stock on any  specified  date,  shall mean (a) the
last  reported  sale  price per  share of  Common  Stock on such date on the OTC
Electronic  Bulletin Board, or if no longer traded thereon,  on the Nasdaq Small
Cap Market or the Nasdaq National  Market,  or if not traded on the Nasdaq Small
Cap Market or the Nasdaq  National  Market,  the last reported sale price on the
principal  national  securities  exchange or the automated  quotation  system on
which the Common Stock is so traded or (b) if such OTC Electronic Bulletin Board
or Nasdaq or other  automated  quotation  system shall report only asked and bid
prices,  or if there  shall  have been no sale of  Common  Stock on such date so
reported,  then  the  average  of the last  reported  asked  price  and the last
reported bid price of Common Stock.

      5.3 Mechanics of Conversion.

            5.3.1 General.  In order to convert any shares of Series B Preferred
Stock into shares of Common Stock, the holder of such shares shall (a) telecopy,
at or prior to 11:59 p.m., New York City time (the "Conversion Notice Deadline")
on the date of  conversion,  a copy of the fully  executed  notice of conversion
("Notice of  Conversion") to the Corporation at the office of the Corporation or
its designated Transfer Agent for the Series B Preferred Stock stating that such
holder elects to convert, which notice shall specify the date of conversion, the
number of shares of Series B Preferred  Stock to be  converted,  the  applicable
Series B Conversion  Price and a  calculation  of the number of shares of Common
Stock issuable upon such  conversion  (together with a copy of the front page of
each  certificate  to be converted) and (b) surrender to a common carrier or the
United States Postal  Service,  for delivery to the office of the Corporation or
the Transfer Agent, the original certificates  representing the shares of Series
B Preferred  Stock being converted (the "Preferred  Stock  Certificates"),  duly
endorsed  for  transfer  to  the  Corporation;   provided,   however,  that  the
Corporation shall not be obligated to issue  certificates  evidencing the shares
of Common Stock issuable upon such conversion  unless either the Preferred Stock
Certificates  are delivered to the Corporation or its Transfer Agent as provided
above,  or such holder  notifies the Corporation or its Transfer

<PAGE>

Agent that such certificates have been lost, stolen or destroyed (subject to the
requirements of Section 5.3.2). Upon receipt by the Corporation of a telecopy of
a Notice of Conversion,  the Corporation  shall within three business days send,
via  telecopier,  a confirmation  of receipt of the Notice of Conversion to such
holder which shall specify that the Notice of  Conversion  has been received and
the name and telephone  number of a contact person at the Corporation  whom such
holder should contact regarding  information  related to the conversion.  In the
case of a dispute as to the calculation of the Conversion  Rate, the Corporation
shall  promptly  issue to such holder the number of Shares that are not disputed
and shall  submit the  disputed  calculations  to its  outside  accountant  (the
"Accountant")  via  telecopier  within  five  business  days of  receipt of such
holder's  Notice of Conversion.  The  Corporation  shall cause the Accountant to
perform  the  calculations  and notify the  Corporation  and such  holder of the
results  no  later  than 48  hours  from  the  time  it  receives  the  disputed
calculations.  The Accountant's  calculation  shall be deemed  conclusive absent
manifest error.

            5.3.2  Lost,  Stolen,  Destroyed  or  Mutilated  Certificates.  Upon
receipt by the  Corporation  of  evidence  of the loss,  theft,  destruction  or
mutilation of any Preferred Stock Certificate(s) representing shares of Series B
Preferred Stock, and (in the case of loss, theft or destruction) of indemnity or
security  reasonably  satisfactory  to the  Corporation,  and upon surrender and
cancellation  of  the  Preferred  Stock   Certificate(s),   if  mutilated,   the
Corporation shall execute and deliver new Preferred Stock Certificate(s) of like
tenor and date. However, the Corporation shall not be obligated to re-issue such
lost,  stolen,  destroyed or mutilated  Preferred  Stock  Certificate(s)  if the
holder thereof contemporaneously requests the Corporation to convert such Series
B Preferred Stock into Common Stock.

            5.3.3 Delivery of Common Stock Upon  Conversion.  The Corporation or
the Transfer Agent (as applicable) shall, no later than the close of business on
the fourth  business day (the  "Deadline")  after receipt by the  Corporation or
Transfer  Agent of a  telecopy  of a Notice of  Conversion  and  receipt  by the
Corporation or the Transfer Agent of all necessary  documentation  duly executed
and in proper form required for  conversion,  including  the original  Preferred
Stock  Certificates to be converted (or after provision for  indemnification  or
security in the case of lost, stolen or destroyed certificate(s),  if required),
issue and surrender to a common  carrier or the United States Postal Service for
either  overnight or (if delivery is outside the United States) two day delivery
(or the shortest period of time in which a recognized  international carrier can
deliver) to the converting  holder at the address of such holder as shown on the
stock  records  of the  Corporation  a  certificate  for the number of shares of
Common Stock to which such holder shall be entitled as aforesaid.

            5.3.4 Cash in Lieu of Fractional  Shares. The Corporation may, if it
so  elects,  issue  fractional  shares  of  Common  Stock or scrip  representing
fractional  shares upon the conversion of shares of Series B Preferred Stock. If
the Corporation does not elect to issue fractional shares, the Corporation shall
pay to the holder of the shares of Series B Preferred Stock which were

<PAGE>

converted a cash  adjustment in respect of such  fractional  shares in an amount
equal to the same fraction of the Closing Price on the Date of  Conversion.  The
determination  as to whether or not any fractional  shares are issuable shall be
based  upon the  total  number  of shares  of  Series B  Preferred  Stock  being
converted at any one time by any holder thereof, not upon each share of Series B
Preferred Stock being converted.

            5.3.5 Date of Conversion. The date on which a conversion occurs (the
"Date of Conversion")  shall be deemed to be the date set forth in the Notice of
Conversion,  provided (a) that the copy of the Notice of  Conversion  is sent by
telecopier to the  Corporation at or prior to 11:59 p.m., New York City time, on
the Date of Conversion,  and (b) that the original  Preferred Stock Certificates
representing  the  shares  of  Series  B  Preferred  Stock to be  converted  are
surrendered by depositing such  certificates with a common carrier or the United
States  Postal  Service,  for delivery to the office of the  Corporation  or the
Transfer Agent and/or,  if any of such Preferred  Stock  Certificates  have been
lost,  stolen or  destroyed,  the holder of such shares  complies  with  Section
5.3.2.  The person or persons  entitled  to receive  the shares of Common  Stock
issuable  upon such  conversion  shall be treated for all purposes as the record
holder or holders of such shares of Common Stock on the Date of  Conversion.  If
the original  Preferred Stock  Certificates  representing the shares of Series B
Preferred  Stock to be  converted  are not  received by the  Corporation  or the
Transfer  Agent,  or if such holder fails to comply with Section  5.3.2,  as the
case may be,  within ten business days after the Date of  Conversion,  or if the
telecopy of the Notice of Conversion is not received by the  Corporation  or its
Transfer  Agent  prior  to  the  Conversion  Notice  Deadline,   the  Notice  of
Conversion, at the Corporation's option, may be declared null and void.

      5.4 Reservation of Stock Issuable Upon Conversion.  The Corporation  shall
at all times  reserve and keep  available  out of its  authorized  but  unissued
shares of Common Stock,  solely for the purpose of effecting  the  conversion of
the Series B Preferred Stock, such number of its shares of Common Stock as shall
from time to time be sufficient to effect the conversion of all then outstanding
shares of Series B Preferred  Stock. If at any time the number of authorized but
unissued shares of Common Stock shall not be sufficient to effect the conversion
of all then outstanding shares of Series B Preferred Stock, the Corporation will
take such  corporate  action as may be necessary to increase its  authorized but
unissued  shares of Common Stock to such number of shares as shall be sufficient
for such purpose;  provided,  however,  that the taking of such action shall not
affect the Corporation's  liability,  if any, for damages arising as a result of
its failure to have a sufficient number of shares reserved.

      5.5  Automatic  Conversion.   Each  share  of  Series  B  Preferred  Stock
outstanding on December 21, 2001,  shall  automatically be converted into shares
of Common Stock on such date at the  applicable  Conversion  Rate then in effect
for such share (calculated in accordance with the formula in Section 5.1 above),
and such date  shall be  deemed  the Date of  Conversion  with  respect  to such
conversion.

<PAGE>

      5.6 Adjustment of Common Stock Issuable Upon Conversion.

            5.6.1  Adjustment Due to Stock Split,  Stock  Dividend,  Etc. If the
number of  outstanding  shares of Common  Stock is  increased  by a stock split,
stock  dividend,  subdivision  of shares or other similar  event,  the Reference
Price and the Series B-2 Conversion Price shall each be proportionately reduced,
or if the  number  of  outstanding  shares  of Common  Stock is  decreased  by a
combination or reclassification of shares, or other similar event, the Reference
Price  and the  Series  B-2  Conversion  Price  shall  each  be  proportionately
increased.  In  addition,  if any such event shall have taken  place  during the
reference period for  determination of the Variable Series B-1 Conversion Price,
then the  Variable  Series  B-1  Conversion  Price  shall be  calculated  giving
appropriate   effect  to  the  stock   split,   stock   dividend,   combination,
reclassification  or other similar  event for all five trading days  immediately
preceding the Date of Conversion.

            5.6.2 Adjustment Due to Merger, Consolidation,  Etc. If, at any time
when any shares of Series B Preferred Stock are outstanding,  there shall be any
merger, consolidation, exchange of shares, recapitalization,  reorganization, or
other  similar  event,  as a  result  of which  shares  of  Common  Stock of the
Corporation  shall be changed  into the same or a different  number of shares of
the same or another class or classes of stock or  securities of the  Corporation
or  another  entity  or  there  is a  sale  of  all  or  substantially  all  the
Corporation's  assets or there is a change of control  transaction not deemed to
be a  liquidation  pursuant  to Section  4.3,  then each  Series B Holder  shall
thereafter  have the right to  receive  upon  conversion  of Series B  Preferred
Stock, upon the basis and upon the terms and conditions  specified herein and in
lieu of the  shares  of  Common  Stock  immediately  theretofore  issuable  upon
conversion,  such stock,  securities  and/or  other  assets  which such Series B
Holder would have been entitled to receive in such  transaction had the Series B
Preferred Stock been converted immediately prior to such transaction, and in any
such case  appropriate  provisions  shall be made with respect to the rights and
interests  of the  holders of the Series B  Preferred  Stock to the end that the
provisions hereof (including, without limitation,  provisions for the adjustment
of the  Series B  Conversion  Price and of the  number of shares  issuable  upon
conversion of the Series B Preferred Stock) shall  thereafter be applicable,  as
nearly  as  may  be  practicable  in  relation  to  any  securities   thereafter
deliverable  upon the  exercise  hereof.  The  Corporation  shall not effect any
transaction  described in this  Section  5.6.2 unless (a) it first uses its best
efforts to give notice  thereof to each Series B Holder 30 days prior to, and in
any event  gives  notice  thereof to each Series B Holder at least 20 days prior
to,  the  record  date  of  such  merger,  consolidation,  exchange  of  shares,
recapitalization, reorganization, or other similar event (during which time each
Series B Holder  shall be  entitled  to convert its shares of Series B Preferred
Stock into Common Stock) and (b) the resulting successor or acquiring entity (if
not the  Corporation)  assumes  by written  instrument  the  obligations  of the
Corporation under this Part B, including this Section 5.6.2.

            5.6.3  Calculation of  Adjustments.  In computing each adjustment to
either  Series B  Conversion  Price,  the result shall

<PAGE>

be rounded to the nearest  thousandth of a cent,  and such  adjustment  shall be
made  separately in each  instance,  and in the event the  adjustment  therefrom
results in a change of the Series B Conversion Price of less than $0.01, then no
adjustment to such then applicable  Series B Conversion Price shall be made, but
the amount of said  adjustment  calculated  thereby shall be carried  forward to
successive  occasions  until such  adjustments in the aggregate  equal or exceed
$0.01.

      Section 6. Redemption.

      6.1 Corporation's Right to Redeem to Prevent Certain Conversions.

            6.1.1 Blocking  Redemption Right. If the Series B-1 Conversion Price
on the Date of  Conversion  with  respect to any shares of Series B-1  Preferred
Stock is less than the Target Price (as hereinafter  defined) on such date, then
the Corporation shall have the right, in its sole discretion (but subject to the
provisions of Section  6.2.3),  to redeem any or all of the shares of Series B-1
Preferred  Stock  otherwise to be converted on such date,  in lieu of conversion
("Blocking Redemption"),  on the Blocking Redemption Date, as defined in Section
6.1.2 at a  redemption  price  for each  such  share  so  redeemed  equal to its
Redemption Price, as defined in Section 6.3 on such Blocking Redemption Date. If
the Corporation  elects to redeem some, but not all, of the shares of Series B-1
Preferred  Stock that would  otherwise be converted on such Date of  Conversion,
the  Corporation  shall  redeem from among such  shares of Series B-1  Preferred
Stock that would otherwise be so converted a pro rata amount from each holder of
any of such shares of Series B-1 Preferred  Stock in accordance  with the number
of shares so submitted for conversion by all such holders.  As used herein,  the
term "Target  Price" shall mean an amount equal to the  Reference  Price,  which
amount shall be adjusted,  however, from time to time in accordance with Section
5.6 and Section 6.6.

            6.1.2 Mechanics of Blocking  Redemption.  If the Corporation desires
to effect a redemption  under this Section 6.1, it shall  deliver  notice of its
election to redeem, by telecopy, at or prior to 5:00 p.m. New York City time the
third business day following  receipt of a Notice of Conversion  from a Series B
Holder  with  respect  to any  shares of Series  B-1  Preferred  Stock,  and the
Corporation  shall provide a copy of such redemption  notice by overnight or two
day carrier,  to (a) the holder of the Series B-1 Preferred  Stock submitted for
conversion at the address and telecopier  number of such holder appearing in the
Corporation's   register  for  the  Series  B-1  Preferred  Stock  and  (b)  the
Corporation's  Transfer Agent. Such redemption notice shall indicate (a) whether
the  Corporation  will  redeem  all or part of the Series  B-1  Preferred  Stock
submitted for conversion,  (b) the applicable  Redemption Price and (c) the date
such redemption  shall become  effective,  which shall be the fifth business day
following  the date such  notice is so sent by  telecopier  to such  holder (the
"Blocking Redemption Date").

      6.2 Corporation's Right to Redeem Generally.

            6.2.1 General Redemption Right. Commencing on December 21,

<PAGE>

1998, the Corporation  shall have the right, in its sole discretion,  to redeem,
from time to time,  any or all of the Series B Preferred  Stock pursuant to this
Section  6.2 (any  such  redemption  being  referred  to  herein  as a  "General
Redemption") at a redemption  price for each such share so redeemed equal to its
Redemption Price, as defined in Section 6.3; provided,  that (a) the Corporation
shall not be  entitled  to  exercise  its right to redeem any shares of Series B
Preferred  Stock  pursuant to this Section 6.2 unless the average of the Closing
Price of the Corporation's  Common Stock for any ten consecutive trading days is
greater  than the  Reference  Price then in effect,  (b) the  Corporation  shall
deliver,  within five trading days after the end of such ten consecutive trading
days,  advance  written notice of such  redemption as provided in Section 6.2.2,
(c) the Corporation  shall only be entitled to redeem on any one occasion either
all the  outstanding  shares of Series B  Preferred  Stock or shares of Series B
Preferred Stock having an aggregate Redemption Price (as defined in Section 6.3)
of at least One Million Dollars ($1,000,000.00) and (d) if at any time any share
of Series B-1 Preferred  Stock and any share of Series B-2  Preferred  Stock are
simultaneously   outstanding,   then  (i)  the  Corporation  may  exercise  such
redemption  right as to any share of Series B-1 Preferred  Stock only if, on the
date the  Corporation's  mailing of its notice of such  redemption  pursuant  to
Section 6.2.2,  the Series B-1  Conversion  Price is greater than the Series B-2
Conversion Price or all shares of Series B-2 Preferred Stock are  simultaneously
redeemed and (ii) the Corporation  may exercise such redemption  right as to any
share of Series B-2  Preferred  Stock only if, on the date of the  Corporation's
mailing of such notice  pursuant  to Section  6.2.2,  the Series B-2  Conversion
Price is greater  than the Series B-1  Conversion  Price or all shares of Series
B-1 Preferred Stock are  simultaneously  redeemed.  If the Corporation elects to
redeem some, but not all, of the shares of Series B-1 Preferred  Stock or Series
B-2 Preferred  Stock,  the Corporation  shall redeem a pro rata amount from each
holder of the Series B-1 Preferred  Stock or Series B-2 Preferred  Stock, as the
case may be, and each such holder may specifically designate which of its shares
of such Series B-1  Preferred  Stock or Series B-2  Preferred  Stock shall be so
redeemed.  Notwithstanding  the foregoing,  the Corporation may not exercise its
redemption right under this Section 6.2 more than once in any 60 day period, nor
within 31 days of the  issuance  of any  shares of Series B  Preferred  Stock in
payment of accrued dividends pursuant to Section 3.1.

            6.2.2  Mechanics of Redemption  at  Corporation's  Election.  If the
Corporation  desires to effect a  redemption  pursuant to this  Section  6.2, it
shall  deliver  prior  written  notice of such  redemption  ("Notice  of General
Redemption")  to (a) the holders of the Series B Preferred  Stock  selected  for
redemption, at the address and telecopier number of such holder appearing in the
Corporation's  register  for the Series B Preferred  Stock and (b) the  Transfer
Agent, which Notice of General Redemption shall be deemed to have been delivered
three  business  days after the  Corporation's  mailing (by overnight or two day
carrier), with a copy sent by telecopier to each such holder on the date of such
mailing, of such Notice of General Redemption. Such Notice of General Redemption
shall  indicate  (a) the number of shares of Series B-1  Preferred  Stock and/or
Series B-2 Preferred Stock that have been selected for redemption,  (b) the date
which such

<PAGE>

redemption  is to become  effective  (the "Date of General  Redemption"),  which
shall be a date not less than 15 days nor more than 30 days  following  the date
such Notice of General Redemption is delivered and (c) the applicable Redemption
Price.

            6.2.3  Holder's  Right  to  Block  Redemption.  Notwithstanding  the
foregoing  provisions  of this  Section  6.2,  each  Series  B  Holder  may,  by
delivering a Notice of  Conversion  pursuant to Section 5.3 within seven trading
days following such holder's receipt of a Notice of General Redemption,  convert
any or all  of  such  holder's  shares  selected  for  redemption,  and no  such
conversion  shall be subject to a Blocking  Redemption  pursuant to Section 6.1;
provided, however, that if the average Closing Price of the Corporation's Common
Stock for the five trading days immediately preceding the date of such Notice of
Conversion  is less than the  Reference  Price then in effect,  then such shares
shall neither be converted  pursuant to such Notice of  Conversion  nor redeemed
pursuant to such Notice of General Redemption nor subject to redemption pursuant
to Section 6.1, and such Notice of General  Redemption  shall be deemed null and
void, ab initio, as to such holder.

      6.3 Redemption Price. The redemption price payable by the Corporation upon
redemption of any share of Series B Preferred  Stock  pursuant to Section 6.1 or
Section 6.2 shall be an amount (the  "Redemption  Price")  equal to the Original
Series B Issue Price,  plus all unpaid  dividends on such share accrued from the
date of issuance to the date of such redemption.

      6.4 Limitations on the Corporation's Redemption Rights.

            6.4.1 Corporation Must Have Immediately  Available Funds on Deposit.
The  Corporation  shall not be entitled to exercise any  redemption  right under
Section 6.1 or Section 6.2, or send any  redemption  notice under Section 6.1 or
Section  6.2 unless it has,  and on the  applicable  redemption  date will have,
funds  legally  available  to effect such  redemption  in full and unless it has
deposited the full amount of the redemption price in cash, available in a demand
or other immediately  available account with a bank or trust corporation  having
aggregate  capital and surplus in excess of $100,000,000 as a trust fund for the
benefit of the  respective  holders of the shares  designated for redemption and
not yet redeemed,  with  irrevocable  instructions  and authority to the bank or
trust  corporation  to pay the  applicable  redemption  price for such shares to
their respective holders on or after the applicable redemption date upon receipt
of notification  from the Corporation that such holder has surrendered its share
certificate pursuant to Section 5 or this Section 6.

            6.4.2 Blackout Period.  Notwithstanding the foregoing  provisions of
this Section 6, the Corporation  may not either send out a redemption  notice or
effect a  redemption  pursuant  to Section  6.1 or Section 6.2 during any period
during which the  Corporation  or any of its officers or directors  are not able
lawfully to buy or sell shares of Common Stock because of the  possession by any
of them of material  non-public  information (a "Blackout  Period"),  unless the
Corporation shall first publicly disclose such non-public information; provided,
however,  that no redemption shall be effected until at least ten\

<PAGE>

days after the  Corporation  shall have given the holder written notice that the
Blackout Period has expired.

      6.5 Payment of Redemption Price.

            6.5.1 Each  holder of any shares of Series B  Preferred  Stock being
redeemed under this Section 6 shall send Preferred Stock Certificates evidencing
such shares to the Corporation or its Transfer Agent, and the Corporation  shall
cause the  applicable  Redemption  Price for each such  share to be paid to such
holder,  in  full,  on the  Date of  Blocking  Redemption  or  Date  of  General
Redemption,  as the case may be;  provided  that the  Corporation  shall  not be
obligated to deliver the Redemption Price for any such share until the Preferred
Stock  Certificate  evidencing such share is delivered to the Corporation or its
Transfer  Agent,  or, in the  event  such  certificate  has been  lost,  stolen,
mutilated or destroyed, until the holder of such share has complied with Section
5.3.2.

            6.5.2 If the  Corporation  elects to redeem  any  shares of Series B
Preferred  Stock pursuant to either  Section 6.1 or Section 6.2 hereof,  and the
Corporation  fails to pay or cause to be paid to any  Series B Holder,  in full,
the  Redemption  Price for any such share so selected for  redemption  from such
holder as and when such  payment is due as provided in Section  6.5.1,  then the
Corporation  shall,  if such  holder has  submitted  a Notice of  Conversion  in
compliance  with Section 5.3 hereof,  convert  such share,  in lieu of redeeming
such share,  into shares of Common  Stock on the date such payment is due (which
date shall be deemed the Date of Conversion  with respect to such conversion for
purposes of Section 5.1),  and the number of shares of Common Stock to be issued
to such Series B Holder upon such  conversion  of such share shall be the number
of shares of Common Stock  determined  using a conversion  price that equals the
lesser of (a) the applicable Series B Conversion Price on the date such Series B
Holder sent its Notice of Conversion to the  Corporation  or the Transfer  Agent
via telecopier,  or (b) the applicable Series B Conversion Price on the date the
Transfer  Agent  issues to such  Series B Holder  certificates  evidencing  such
shares of Common  Stock  pursuant to this  Section  6.5.2.  The issuance of such
shares shall not affect the Corporation's  liability to any such Series B Holder
for damages,  if any, arising as a result of its failure timely to redeem and to
pay the full amount of the  redemption  price payable to such holder as provided
herein.

      6.6  Adjustment  of Target  Price.  In addition to any  adjustment  to the
Target Price  resulting from any  adjustment to the Reference  Price pursuant to
Section 5, the Target Price shall also be subject to  adjustment  as provided in
this Section 6.6.

            6.6.1 Upon the Issuance of Common Stock

      (a) Issuance of Common Stock.  If the Corporation  shall,  while there are
any shares of Series B  Preferred  Stock  outstanding,  issue or sell  shares of
Common  Stock  without  consideration  or at a price  per  share  less  than the
Applicable Market Price, as hereinafter defined, as of the date of such issuance
or sale then,  in each such case,  the Target Price shall upon such  issuance or
sale, except as hereinafter  provided, be

<PAGE>

lowered  so as to be equal to an amount  determined  by  multiplying  the Target
Price by a fraction:

            (i) the  numerator  of which  shall be (x) the  number  of shares of
Common Stock  outstanding  immediately  prior to the issuance of such additional
shares of Common Stock,  plus (y) the number of shares of Common Stock which the
net aggregate  consideration,  if any, received by the Corporation for the total
number of such additional shares of Common Stock so issued would purchase at the
Applicable Market Price then in effect, and

            (ii) the  denominator  of which shall be (x) the number of shares of
Common Stock  outstanding  immediately  prior to the issuance of such additional
shares of Common Stock plus (y) the number of such  additional  shares of Common
Stock so issued.

      As used  herein,  the term  "Applicable  Market  Price"  as of any date of
determination means 85% of the average Closing Price, as that term is defined in
Section  5.2.4,  of the  Corporation's  Common  Stock for the five  trading days
immediately preceding such date of determination.

      (b) Upon Issuance of Warrants, Options and Rights to Common Stock.

            (i) For the  purposes of this  Section  6.6.1,  the  issuance of any
warrants,  options,  subscriptions  or purchase rights with respect to shares of
Common Stock and the issuance of any securities convertible into or exchangeable
for shares of Common  Stock (or the  issuance  of any  warrants,  options or any
rights with respect to such  convertible or  exchangeable  securities)  shall be
deemed an issuance of such  Common  Stock at such time if the Net  Consideration
Per Share (as hereinafter  defined) which may be received by the Corporation for
such Common Stock shall be less than the Applicable  Market Price at the time of
such issuance.  Any  obligation,  agreement or  undertaking  to issue  warrants,
options,  subscriptions  or purchase  rights at any time in the future  shall be
deemed to be an issuance at the time such  obligation,  agreement or undertaking
is made or arises.  No  adjustment  of the Target Price shall be made under this
Section  6.6.2 upon the  issuance of any shares of Common Stock which are issued
pursuant to the exercise of any  warrants,  options,  subscriptions  or purchase
rights or pursuant to the exercise of any  conversion or exchange  rights in any
convertible  securities if any  adjustment  shall  previously  have been made or
deemed not required hereunder, upon the issuance of any such warrants,  options,
or  subscription  or purchase  rights or upon the  issuance  of any  convertible
securities  (or  upon  the  issuance  of any  warrants,  options  or any  rights
therefor) as above provided.

      Should  the Net  Consideration  Per Share of any such  warrants,  options,
subscriptions  or purchase  rights or  convertible  securities be decreased from
time to time, then, upon the effectiveness of each such change, the Target Price
shall be  adjusted  to such  Target  Price as would  have  obtained  (1) had the
adjustments  made  upon  the  issuance  of such  warrants,  options,  rights  or
convertible   securities   been  made  upon  the  basis  of  the  decreased  Net
Consideration  Per Share of such securities and (2) had adjustments  made to the
Target  Price  since the date of issuance  of such  securities  been made to the
Target Price as

<PAGE>

adjusted  pursuant to (1) above. Any adjustment of the Target Price with respect
to this paragraph which relates to warrants,  options,  subscriptions,  purchase
rights or convertible securities with respect to shares of Common Stock shall be
disregarded   if,  as,   when  and  to  the  extent  such   warrants,   options,
subscriptions,  purchase rights or convertible securities expire or are canceled
without  being  exercised  or  converted,  so that the  Target  Price  effective
immediately  upon such  cancellation or expiration  shall be equal to the Target
Price in effect at the time of the issuance of the expired or canceled warrants,
options,  subscriptions,  purchase  rights or convertible  securities  with such
additional  adjustments  as would  have  been made to the  Target  Price had the
expired  or  canceled  warrants,  options,  subscriptions,  purchase  rights  or
convertible securities not been issued.

            (ii) For purposes of this Section  6.6, the "Net  Consideration  Per
Share" which may be received by the Corporation shall be determined as follows:

                  (x) The "Net  Consideration  Per Share"  shall mean the amount
equal to the total amount of consideration,  if any, received by the Corporation
for the issuance of such  warrants,  options,  subscriptions  or other  purchase
rights or convertible  or  exchangeable  securities,  plus the minimum amount of
consideration,  if any,  payable to the Corporation  upon exercise or conversion
thereof, divided by the aggregate number of shares of Common Stock that would be
issued if all such warrants, options,  subscriptions or other purchase rights or
convertible or exchangeable securities were exercised, exchanged or converted.

                  (y) The "Net Consideration Per Share" which may be received by
the Corporation  shall be determined in each instance as of the date of issuance
of warrants, options,  subscriptions, or other purchase rights or convertible or
exchangeable  securities  without  giving  effect to any possible  future upward
price  adjustments or rate  adjustments  which may be applicable with respect to
such warrants, options,  subscriptions,  or other purchase rights or convertible
or exchangeable securities.

      (c) Determination of Consideration.  For purposes of this Section 6.6, (i)
the amount of  consideration  received by or payable to the  Corporation for the
issuance  of any shares of Common  Stock or of any of the  securities  or rights
described  in  this  Section  6.6  shall  be  deemed  to be the  amount  of such
consideration received by or payable to the Corporation for such issuance, after
deducting  therefrom any  compensation or discount in the sale,  underwriting or
purchase  thereof  by  underwriters  or  dealers  or others  performing  similar
services or for any expenses  incurred in  connection  therewith,  and (ii) if a
part or all of the consideration  received by the Corporation in connection with
the  issuance  of  shares  of the  Common  Stock or the  issuance  of any of the
securities  or rights  described in this Section 6.6 consists of property  other
than cash, such consideration  shall be deemed to have a fair market value as is
reasonably   determined  in  good  faith  by  the  Board  of  Directors  of  the
Corporation.

      (d) Exceptions. This Section 6.6.1 shall not apply to (a)

<PAGE>

shares  issued as a stock  split or stock  dividend  or (b) shares  issued  upon
conversion of shares of Series A or Series B Preferred Stock.

            6.6.2  Calculations.  In  computing  each  adjustment  to the Target
Price, the result shall be rounded to the nearest thousandth of a cent, and such
adjustment  shall be made  separately  in each  instance,  and in the  event the
adjustment therefrom results in a change of the Target Price of less than $0.01,
then no adjustment to such then  applicable  Target Price shall be made, but the
amount  of said  adjustment  calculated  thereby  shall be  carried  forward  to
successive  occasions  until such  adjustments in the aggregate  equal or exceed
$0.01.

      Section 7. Advance Notice of Redemption.

      7.1 Holder's  Right to Elect to Receive  Notice of Cash  Redemption by the
Corporation.  Each  Series  B  Holder  shall  have  the  right  to  require  the
Corporation  to provide  advance  notice stating  whether the  Corporation  will
redeem such holder's shares of Series B Preferred Stock pursuant to Section 6.1.

      7.2 Mechanics of Holder's  Election  Notice. A Series B Holder desiring to
exercise its rights under this Section 7 shall send notice  ("Election  Notice")
to the Corporation  and such other person as the Corporation may designate,  via
telecopier,  requesting the Corporation to disclose whether, if such holder were
to exercise its right of conversion pursuant to Section 5 with respect to all or
a specified number of shares of Series B Preferred Stock, the Corporation  would
elect to redeem any or all of such shares of Series B  Preferred  Stock for cash
in lieu of issuing  Common  Stock.  The  Corporation  shall then be  required to
disclose  to such  holder  what  action  the  Corporation  would  take  over the
subsequent 20 business day period,  including the date of such Election  Notice,
as further provided in Section 7.3.

      7.3 Corporation's Response. Upon receipt by the Corporation of an Election
Notice,  the Corporation shall immediately send, via telecopier,  a confirmation
of receipt of the Election Notice to the holder submitting such Election Notice,
which  confirmation shall specify that the Election Notice has been received and
the name and telephone  number of a contact person at the Corporation  whom such
holder should contact  regarding  information  related to the requested  advance
notice.  Thereafter the Corporation must respond by the close of business on the
third business day following  receipt of such holder's  Election  Notice (a) via
telecopier  and (b) by  depositing  such  response  with an overnight or two day
carrier.  The  Corporation's  response  must state  whether it would  redeem the
shares, in whole or in part (and, if in part, the number of such shares it would
redeem), or allow conversion into shares of Common Stock without redemption.  If
the  Corporation  does not respond to such holder within three business days via
telecopier and overnight or two day carrier,  the Corporation  shall be required
to issue to such holder  Common Stock upon such  holder's  conversion  within 20
business  days  following  such  holder's  Election  Notice.   However,  if  the
Corporation's  Common  Stock  price  decreases  so  that  under  the  applicable
Conversion  Rate  the  Corporation  would be  required  to  issue  more  than an
additional twenty percent (20%) of shares of Common Stock other than such holder
was entitled to receive

<PAGE>

at the time such holder sent its Election Notice,  then the Corporation shall no
longer be bound to convert such holder's  Preferred  Stock into Common Stock but
may elect to redeem  such  shares  pursuant  to Section  6.1, in which case such
holder may block such redemption by delivering to the Corporation written notice
rescinding  its Notice of Conversion  within two business days of its receipt of
the  Corporation's  redemption  notice under Section 6.2. If the holder delivers
such a rescission  notice,  then such shares shall neither be converted pursuant
to the holder's Notice of Conversion nor redeemed pursuant to Section 6.1.

      Section 8. Voting  Rights.  Except as otherwise  provided by New York law,
the  holders  of the  Series  B  Preferred  Stock  shall  have no  voting  power
whatsoever, and shall not be entitled, as such, to vote or otherwise participate
in any  proceeding  in which actions  shall be taken by the  Corporation  or the
shareholders  thereof or be entitled,  as such, to receive notice of any meeting
of the shareholders.

      Notwithstanding  the above,  the  Corporation  shall provide each Series B
Holder  with not less than 20 days' prior  written  notice of any meeting of the
shareholders regarding any major corporate events affecting the Corporation.  In
the event of any taking by the Corporation of a record of its  shareholders  for
the purpose of determining  shareholders  who are entitled to receive payment of
any  dividend or other  distribution,  any right to subscribe  for,  purchase or
otherwise  acquire  any share of any class or any other  securities  or property
(including by way of merger, consolidation or reorganization), or to receive any
other right, or for the purpose of determining  shareholders who are entitled to
vote in  connection  with  any  proposed  sale,  lease or  conveyance  of all or
substantially all of the assets of the Corporation, or any proposed liquidation,
dissolution  or  winding up of the  Corporation,  the  Corporation  shall mail a
notice to each  Series B  Holder,  at least ten days  prior to the  record  date
specified  therein,  of the date on which any such record is to be taken for the
purpose  of such  dividend,  distribution,  right  or other  event,  and a brief
statement  regarding  the amount and character of such  dividend,  distribution,
right or other event to the extent known at such time.

      To the extent  that under New York law the vote of the holders of Series B
Preferred Stock,  voting separately as a class, is required to authorize a given
action of the Corporation,  the affirmative vote or consent of the holders of at
least a majority of the outstanding  shares of Series B Preferred  Stock, as the
case may be,  represented at a duly held meeting at which a quorum is present or
by written consent of a majority of the outstanding shares of Series B Preferred
Stock,  as the case may be,  (except as otherwise may be required under New York
law) shall  constitute  the approval of such action by the class.  To the extent
that under New York law the holders of the Series B Preferred Stock are entitled
to vote on a matter with holders of Common Stock,  voting together as one class,
each share of Series B  Preferred  Stock  shall be entitled to a number of votes
equal to the number of shares of Common Stock into which it is then  convertible
using the record date for the taking of such vote of shareholders as the date on
which a Series  B  Conversion  Price  is  calculated.  Holders  of the  Series B
Preferred Stock also shall

<PAGE>

be  entitled to notice of all  shareholder  meetings  or written  consents  with
respect to which they would be entitled to vote,  which notice would be provided
pursuant to the Corporation's By-Laws and applicable statutes.

      Section 9. Protective Provision.

      9.1 So long as any share of Series B Preferred Stock is  outstanding,  the
Corporation  may not,  without first  obtaining the approval (by vote or written
consent, as provided by the New York Business Corporation Law) of the holders of
at least two-thirds of the then outstanding shares of Series B Preferred Stock:

      (a)  alter  or  change   (whether  by  amendment  of  its  Certificate  of
Incorporation or By-Laws or otherwise) the rights,  preferences or privileges of
any other class of equity  securities  so as to affect  adversely the Series B-1
Preferred Stock or the Series B-2 Preferred Stock;

      (b)  alter  or  change   (whether  by  amendment  of  its  Certificate  of
Incorporation  or  By-Laws  or  otherwise)  any of the  rights,  preferences  or
privileges of the Series B-1 Preferred Stock or the Series B-2 Preferred Stock;

      (c) authorize or issue any share of any other equity security senior to or
having a preference over or on parity with the Series B-1 Preferred Stock or the
Series B-2  Preferred  Stock with  respect to  dividends  or  Distributions  (as
defined in Section 2 above);

      (d) increase the authorized  number of shares of Series A Preferred  Stock
or Series B Preferred Stock;

      (e) redeem,  purchase or  otherwise  acquire for value (or pay into or set
aside for a sinking  fund for such  purpose)  any share of capital  stock of the
Corporation  other than (i) through  redemption  or  conversion  pursuant to the
provisions of Part A or this Part B, (ii)  repurchases of Common Stock, or (iii)
redemptions of other securities  convertible into shares of Common Stock made to
block such conversion.

      (f)  declare  or pay  any  dividend  on,  or  declare  or make  any  other
distribution on account of, its Common Stock or any class or series of Preferred
Stock other than the Series B Preferred  Stock  (other  than  dividends  payable
solely  in  shares  of  Common  Stock or  distributions  on  shares  of Series A
Preferred  Stock  required to be made under Part A) or set apart any sum for any
such purpose; or

      (g) do any act or thing  not  authorized  or  contemplated  by this Part B
which  would  result in  taxation  of the  holders  of  shares  of the  Series B
Preferred  Stock under  Section 305 of the  Internal  Revenue  Code of 1986,  as
amended (or any comparable  provision of the Internal  Revenue Code as hereafter
from time to time amended).

      9.2 In the event holders of at least  two-thirds  of the then  outstanding
shares of Series B Preferred  Stock agree to allow the  Corporation  to alter or
change the rights, preferences or

<PAGE>

privileges of the shares of Series B Preferred Stock,  pursuant to clause (a) or
clause (b) of Section 9.1 above,  so as to affect the Series B Preferred  Stock,
then the Corporation  will deliver notice of such approved change to each holder
of Series B Preferred  Stock that did not agree to such  alteration or change (a
"Dissenting  Holder")  and each  Dissenting  Holder  shall  have the right for a
period  of 30  business  days to  convert  any or all of its  shares of Series B
Preferred Stock pursuant to the terms of this Part B as they exist prior to such
alteration or change  (notwithstanding  the one-year waiting period set forth in
Section 5.1 hereof), or continue to hold its shares of Series B Preferred Stock.

      Section 10. Status of Redeemed or Converted Stock. In the event any shares
of Series A  Preferred  Stock or Series B  Preferred  Stock shall be redeemed or
converted,  the shares so converted or redeemed shall be canceled,  shall return
to the status of authorized but unissued Preferred Stock of no designated series
and shall not be issuable  by the  Corporation  as Series A  Preferred  Stock or
Series B Preferred Stock.

      Section 11. Notices of Record Date. In the event of:

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

      (b) any capital reorganization of the Corporation, any reclassification or
recapitalization  of the  capital  stock of the  Corporation,  any merger of the
Corporation  or any  transfer of all or  substantially  all of the assets of the
Corporation to any other corporation or any other entity or person, or

      (c) any voluntary or involuntary dissolution, liquidation or winding up of
the Corporation,

then and in each such event the Corporation  shall mail or cause to be mailed to
each  holder of Series B  Preferred  Stock a notice  specifying  (i) the date on
which  any  such  record  is to be  taken  for the  purpose  of  such  dividend,
distribution or right and a description of such dividend, distribution or right,
(ii)   the   date  on   which   any   such   reorganization,   reclassification,
recapitalization,  transfer, merger,  dissolution,  liquidation or winding up is
expected to become effective and (iii) the time, if any, that is to be fixed, as
to when the  holders of record of Common  Stock (or other  securities)  shall be
entitled to exchange  their  shares of Common  Stock (or other  securities)  for
securities   or   other   property   deliverable   upon   such   reorganization,
reclassification,  recapitalization,  transfer, merger, dissolution, liquidation
or winding up. Such notice shall be mailed at least ten  business  days prior to
the date specified in such notice on which such action is to be taken.

      Section 12. No Impairment.  The Corporation  will not, by amendment of its
Certificate of Incorporation or through any reorganization,  transfer of assets,
consolidation,  merger,  dissolution,  issue or sale of  securities or any other
voluntary

<PAGE>

action, avoid or seek to avoid the observance or performance of any of the terms
of the Series B Preferred Stock set forth herein,  but will at all times in good
faith assist in the carrying out of all such terms and in the taking of all such
actions as may be necessary or appropriate in order to protect the rights of the
holders of the Series B Preferred  Stock against  dilution or other  impairment.
Without  limiting the generality of the foregoing,  the Corporation (a) will not
increase the par value of any shares of stock  receivable  on the  conversion of
any shares of Series B Preferred Stock above the amount payable therefor on such
conversion  and (b) will take all such action as may be necessary or appropriate
in order that the  Corporation  may  validly  and  legally  issue fully paid and
nonassessable  shares  of stock on the  conversion  of all  shares  of  Series B
Preferred Stock from time to time outstanding.

Part C.  Series C Preferred Stock.

         One  Thousand  Two  Hundred  (1,200)  of the Ten  Million  (10,000,000)
authorized  shares of Preferred Stock of the  Corporation are hereby  designated
Series C  Preferred  Stock,  par value  $.05 per share.  (References  to section
numbers in this Part C of Article  FOURTH of the  Certificate  of  Incorporation
("Part C") shall refer only to such sections in this Part C of Article

<PAGE>

FOURTH,  unless otherwise expressly stated herein.) The Series C Preferred Stock
shall possess the rights and preferences set forth below:

         Section 1.  Designations  and Amounts.  The shares of such series shall
have a par value of $.05 per share and shall be designated as Series C Preferred
Stock (the "Series C Preferred Stock") and the number of shares constituting the
Series C Preferred Stock shall be One Thousand  (1,000).  The Series C Preferred
Stock shall be offered at a purchase price of One Thousand  Dollars  ($1,000.00)
per share (the "Original Series C Issue Price").

         Section 2. Rank. The Series C Preferred Stock shall rank: (a) junior to
any other class or series of capital stock of the Corporation  hereafter created
specifically  ranking  by its  terms  senior  to the  Series C  Preferred  Stock
(collectively,  the "Senior Securities");  (b) prior to all of the Corporation's
Common Stock, $.01 par value per share ("Common Stock");  (c) prior to any class
or series of capital stock of the Corporation hereafter created not specifically
ranking by its terms senior to or on parity with any Series C Preferred Stock of
whatever subdivision (collectively, with the Common Stock, "Junior Securities");
and (d) on parity with the Series A Preferred Stock and Series B Preferred Stock
and any class or series of capital stock of the  Corporation  hereafter  created
specifically  ranking by its terms on parity with the Series C  Preferred  Stock
("Parity   Securities")  in  each  case  as  to  distributions  of  assets  upon
liquidation,  dissolution or winding up of the Corporation, whether voluntary or
involuntary   (all  such   distributions   being  referred  to  collectively  as
"Distributions") and as to dividends.

         Section 3.        Dividends.

                           3.1  Cumulative  Dividends.  The  holders of Series C
Preferred  Stock (the "Series C Holders")  shall be entitled to receive,  out of
funds legally available therefor,  cumulative annual dividends at an annual rate
per share equal to six percent (6%) of the Original  Series C Issue Price.  Such
dividends shall accrue on each share of Series C Preferred Stock from day to day
from the date of issue  and shall be  cumulative  until  paid upon  liquidation,
dissolution  or winding up of the  Corporation  within the  meaning of Section 4
hereof or upon redemption as provided in Section 6 hereof or until such share is
converted into Common Stock as provided in Section 5 hereof,  and such dividends
shall so accrue  whether or not earned or declared  and whether or not there are
profits,  surplus or other funds of the  Corporation  legally  available for the
payment of dividends.  If such  cumulative  dividends in respect of any prior or
current annual  dividend  period shall not have been declared and paid, then the
deficiency  shall first be fully paid before any dividend or other  distribution
shall  be paid or  declared  and set  apart  with  respect  to any  class of the
Corporation's capital stock, now or hereafter outstanding.  Cumulative dividends
with respect to shares of Series C Preferred  Stock which are  accrued,  payable
and/or in  arrears  shall be paid on May 21 of each year  commencing  on May 21,
2000 and each May 21 thereafter being referred to herein as a "Dividend  Payment
Date"), to the extent assets are legally available  therefor and any amounts for
which assets are not legally  available  shall be paid  promptly  thereafter  as
assets become legally  available  therefor;  any partial payment will be made to
the Series C Holders pro rata in accordance  with their holdings of such shares.
On any Dividend Payment Date dividends on shares of Series C Preferred Stock may

<PAGE>

be paid through the issuance of  additional  shares of Series C Preferred  Stock
equal in number to the amount of such dividends divided by $1,000.

                           3.2  Reservation of Stock Issuable as Dividends.  The
Corporation  shall at all times reserve and keep available out of its authorized
but unissued  shares of Common  Stock,  solely for the purpose of effecting  the
payment of dividends on the Series C Preferred Stock as provided in Section 3.1,
such number of shares of Series C Preferred  Stock as shall from time to time be
sufficient  to  effect  such  payment  on all  outstanding  shares  of  Series C
Preferred  Stock. If at any time the number of authorized but unissued shares of
Common Stock shall not be sufficient  to effect such payment on all  outstanding
shares of Series C Preferred  Stock,  the  Corporation  will take such corporate
action as may be  necessary to increase its  authorized  but unissued  shares of
such number of shares as shall be sufficient for such purpose.

         Section 4.        Liquidation Preference.

                           4.1 In the event of any  liquidation,  dissolution or
winding up of the Corporation,  either voluntary or involuntary,  the holders of
shares of Series C Preferred  Stock  shall be  entitled to receive,  immediately
after any  distributions  to Senior  Securities  required  by the  Corporation's
Certificate of  Incorporation,  and prior in preference to any  distribution  to
Junior Securities but in parity with any distribution to Parity  Securities,  an
amount per share equal to the sum of (a) the  Original  Series C Issue Price for
each  outstanding  share of Series C Preferred  Stock and (b) an amount equal to
all accrued and unpaid  dividends  thereon,  whether or not declared,  since the
date of issue up to and including the date full payment shall have been tendered
to the Series C Holders with respect to such liquidation, dissolution or winding
up (collectively,  the "Series C Liquidation Amount").  If, after the occurrence
of any such  liquidation,  dissolution  or winding up and payment in full of the
preferential amounts with respect to the Senior Securities, the assets and funds
available to be  distributed  among the holders of the Series C Preferred  Stock
and  Parity  Securities  shall be  insufficient  to permit  the  payment to such
holders  of the full  preferential  amounts  due to the  holders of the Series C
Preferred Stock and the Parity Securities,  respectively, then the entire assets
and  funds  of the  Corporation  legally  available  for  distribution  shall be
distributed  among the  holders of the Series C  Preferred  Stock and the Parity
Securities,  pro rata, based on the respective liquidation amounts to which each
such  series  of  stock  is  entitled  by  the   Corporation's   Certificate  of
Incorporation.

                           4.2 Upon the completion of the distribution  required
by Section 4.1, if assets remain in the  Corporation,  they shall be distributed
to holders of Junior Securities in accordance with the Corporation's Certificate
of Incorporation.

         Section  5.  Conversion.  The Series C Holders  shall  have  conversion
rights as follows (the "Conversion Rights"):

                           5.1  Holders'  Right to  Convert.  Each holder of any
share of Series C Preferred  Stock  shall be  entitled to convert  such share of
Series C Preferred  Stock,  at any time after the  issuance of such share by the
Corporation, into a number of fully-paid and non-

<PAGE>

assessable  shares of Common Stock of the Corporation equal to the quotient that
is  obtained  when the  Original  Series C Issue  Price for such  share plus any
accrued  and  unpaid  dividends  on such  share  is  divided  by the  applicable
Conversion  Price.  As used  herein,  the phrase  "Conversion  Price" shall mean
either of the following: (1) where the Notice of Conversion with respect to such
share is delivered to the  Corporation  not more than ninety calendar days after
the  issuance of such share by the  Corporation,  $6.00 (the  "Fixed  Conversion
Price");  or (2) where the Notice of  Conversion  with  respect to such share is
delivered to the  Corporation  more than ninety calendar days after the issuance
of such share by the  Corporation,  the lesser of (x) the Fixed Conversion Price
and  (y)  eighty-five  percent  (85%)  of  the  average  Closing  Price  of  the
Corporation's  Common Stock for the five trading days immediately  preceding the
Date of  Conversion,  but  not  less  than  fifty  percent  (50%)  of the  Fixed
Conversion Price (the "Variable Conversion Price").

                           The phrase "Closing Price," as used with reference to
shares of Common Stock on any specified  date,  shall mean (a) the last reported
sale price per share of Common Stock on such date on the OTC Electronic Bulletin
Board,  or if no longer  traded  thereon,  on the Nasdaq Small Cap Market or the
Nasdaq National  Market,  or if not traded on the Nasdaq Small Cap Market or the
Nasdaq National Market,  the last reported sale price on the principal  national
securities  exchange or the automated quotation system on which the Common Stock
is so traded  or (b) if such OTC  Electronic  Bulletin  Board or Nasdaq or other
automated  quotation system shall report only asked and bid prices,  or if there
shall  have been no sale of  Common  Stock on such  date so  reported,  then the
average of the last  reported  asked  price and the last  reported  bid price of
Common  Stock.  The  Conversion  Price  shall be  adjusted  from time to time in
accordance with this Section 5.

                    5.2 Automatic  Conversion.  Each share of Series C Preferred
Stock  shall,  on the third  anniversary  of the  issuance  of such share by the
Corporation,  be  automatically  converted  into that number of  fully-paid  and
non-assessable  shares of Common Stock of the Corporation  equal to the quotient
that is obtained when the Original  Series C Issue Price for such share plus any
accrued and unpaid dividends on such share is divided by the Variable Conversion
Price.  Such date shall be deemed the Date of  Conversion  with  respect to such
conversion.

                    5.3 Mechanics of Conversion.

                           5.3.1  General.  In order to  convert  any  shares of
Series C Preferred Stock into shares of Common Stock,  the holder of such shares
shall  (a)  telecopy,  at or prior to  11:59  p.m.,  New  York  City  time  (the
"Conversion  Notice  Deadline") on the date of  conversion,  a copy of the fully
executed notice of conversion ("Notice of Conversion") to the Corporation at the
office of the  Corporation  or its  designated  Transfer  Agent for the Series C
Preferred  Stock stating that such holder elects to convert,  which notice shall
specify the date of conversion, the number of shares of Series C Preferred Stock
to be converted, the applicable Conversion Price and a calculation of the number
of shares of Common Stock issuable upon such conversion (together with a copy of
the front page of each  certificate  to be  converted) and

<PAGE>

(b)  surrender to a common  carrier or the United  States  Postal  Service,  for
delivery to the office of the  Corporation or the Transfer  Agent,  the original
certificates representing the shares of Series C Preferred Stock being converted
(the  "Preferred  Stock  Certificates"),  duly  endorsed  for  transfer  to  the
Corporation;  provided,  however, that the Corporation shall not be obligated to
issue  certificates  evidencing  the shares of Common Stock  issuable  upon such
conversion  unless either the Preferred Stock  Certificates are delivered to the
Corporation or its Transfer Agent as provided above, or such holder notifies the
Corporation or its Transfer Agent that such  certificates have been lost, stolen
or destroyed (subject to the requirements of Section 5.3.2). Upon receipt by the
Corporation  of a telecopy  of a Notice of  Conversion,  the  Corporation  shall
within three business days send, via  telecopier,  a confirmation  of receipt of
the Notice of  Conversion  to such holder which shall specify that the Notice of
Conversion  has been  received  and the name and  telephone  number of a contact
person at the Corporation whom such holder should contact regarding  information
related to the conversion. In the case of a dispute as to the calculation of the
Conversion Rate, the Corporation  shall promptly issue to such holder the number
of Shares that are not disputed and shall  submit the disputed  calculations  to
its outside  accountant (the  "Accountant")  via telecopier within five business
days of receipt of such holder's  Notice of Conversion.  The  Corporation  shall
cause the Accountant to perform the  calculations and notify the Corporation and
such holder of the results no later than 48 hours from the time it receives  the
disputed calculations.  The Accountant's  calculation shall be deemed conclusive
absent manifest error.

                           5.3.2   Lost,   Stolen,    Destroyed   or   Mutilated
Certificates.  Upon receipt by the  Corporation of evidence of the loss,  theft,
destruction  or mutilation of any Preferred  Stock  Certificate(s)  representing
shares  of  Series  C  Preferred  Stock,  and (in the  case of  loss,  theft  or
destruction)   of  indemnity  or  security   reasonably   satisfactory   to  the
Corporation,  and  upon  surrender  and  cancellation  of  the  Preferred  Stock
Certificate(s),  if  mutilated,  the  Corporation  shall execute and deliver new
Preferred Stock  Certificate(s) of like tenor and date. However, the Corporation
shall not be obligated  to re-issue  such lost,  stolen,  destroyed or mutilated
Preferred Stock Certificate(s) if the holder thereof contemporaneously  requests
the Corporation to convert such Series C Preferred Stock into Common Stock.

                           5.3.3 Delivery of Common Stock Upon  Conversion.  The
Corporation or the Transfer Agent (as applicable) shall, no later than the close
of business on the fourth  business day (the  "Deadline")  after  receipt by the
Corporation  or  Transfer  Agent of a  telecopy  of a Notice of  Conversion  and
receipt by the Corporation or the Transfer Agent of all necessary  documentation
duly executed and in proper form required for conversion, including the original
Preferred   Stock   Certificates   to  be  converted  (or  after  provision  for
indemnification   or  security  in  the  case  of  lost,   stolen  or  destroyed
certificate(s),  if required),  issue and  surrender to a common  carrier or the
United States Postal Service for either overnight or (if delivery is outside the
United  States)  two day  delivery  (or the  shortest  period of time in which a
recognized  international  carrier can deliver) to the converting  holder at the
address  of such  holder  as shown on the stock  records  of the  Corporation  a
certificate  for the number of shares of Common Stock to which such holder shall
be entitled as aforesaid.

<PAGE>

                           5.3.4  Cash  in  Lieu  of  Fractional   Shares.   The
Corporation  may, if it so elects,  issue  fractional  shares of Common Stock or
scrip  representing  fractional shares upon the conversion of shares of Series C
Preferred Stock. If the Corporation  does not elect to issue fractional  shares,
the  Corporation  shall pay to the  holder of the  shares of Series C  Preferred
Stock  which were  converted  a cash  adjustment  in respect of such  fractional
shares in an amount equal to the same  fraction of the Closing Price on the Date
of Conversion.  The determination as to whether or not any fractional shares are
issuable  shall be based upon the total  number of shares of Series C  Preferred
Stock being converted at any one time by any holder thereof, not upon each share
of Series C Preferred Stock being converted.

                           5.3.5  Date  of  Conversion.  The  date  on  which  a
conversion occurs (the "Date of Conversion")  shall be deemed to be the date set
forth in the Notice of  Conversion,  provided (a) that the copy of the Notice of
Conversion is sent by telecopier to the  Corporation  at or prior to 11:59 p.m.,
New York  City  time,  on the  Date of  Conversion,  and (b)  that the  original
Preferred Stock Certificates representing the shares of Series C Preferred Stock
to be converted are  surrendered by depositing such  certificates  with a common
carrier or the United States Postal  Service,  for delivery to the office of the
Corporation  or the  Transfer  Agent  and/or,  if any of  such  Preferred  Stock
Certificates  have been lost,  stolen or  destroyed,  the holder of such  shares
complies  with  Section  5.3.2.  The person or persons  entitled  to receive the
shares of Common Stock  issuable upon such  conversion  shall be treated for all
purposes as the record  holder or holders of such shares of Common  Stock on the
Date of Conversion.  If the original Preferred Stock  Certificates  representing
the shares of Series C Preferred  Stock to be converted  are not received by the
Corporation  or the  Transfer  Agent,  or if such  holder  fails to comply  with
Section  5.3.2,  as the case may be,  within ten business days after the Date of
Conversion,  or if the telecopy of the Notice of  Conversion  is not received by
the Corporation or its Transfer Agent prior to the Conversion  Notice  Deadline,
the Notice of Conversion,  at the Corporation's option, may be declared null and
void.

                    5.4  Reservation  of Stock  Issuable  Upon  Conversion.  The
Corporation  shall at all times reserve and keep available out of its authorized
but unissued  shares of Common  Stock,  solely for the purpose of effecting  the
conversion of the Series C Preferred Stock,  such number of its shares of Common
Stock as shall from time to time be sufficient  to effect the  conversion of all
then  outstanding  shares of Series C Preferred Stock. If at any time the number
of  authorized  but unissued  shares of Common Stock shall not be  sufficient to
effect  the  conversion  of all then  outstanding  shares of Series C  Preferred
Stock,  the Corporation  will take such corporate  action as may be necessary to
increase its  authorized  but unissued  shares of Common Stock to such number of
shares as shall be sufficient  for such  purpose;  provided,  however,  that the
taking of such action shall not affect the Corporation's  liability, if any, for
damages arising as a result of its failure to have a sufficient number of shares
reserved.

<PAGE>

                    5.5 Adjustment of Common Stock Issuable Upon Conversion.

                           5.5.1 Adjustment Due to Stock Split,  Stock Dividend,
Etc. If the number of outstanding shares of Common Stock is increased by a stock
split,  stock dividend,  subdivision of shares or other similar event, the Fixed
Conversion Price and Conversion Price shall each be proportionately  reduced, or
if  the  number  of  outstanding  shares  of  Common  Stock  is  decreased  by a
combination or  reclassification  of shares,  or other similar event,  the Fixed
Conversion  Price  and  the  Conversion  Price  shall  each  be  proportionately
increased.  In  addition,  if any such event shall have taken  place  during the
reference period for  determination of the Variable  Conversion  Price, then the
Variable  Conversion Price shall be calculated giving  appropriate effect to the
stock split,  stock  dividend,  combination,  reclassification  or other similar
event for all five trading days immediately preceding the Date of Conversion.

                           5.5.2 Adjustment Due to Merger,  Consolidation,  Etc.
If, at any time when any  shares of Series C  Preferred  Stock are  outstanding,
there shall be any merger, consolidation,  exchange of shares, recapitalization,
reorganization,  or other similar  event,  as a result of which shares of Common
Stock of the Corporation shall be changed into the same or a different number of
shares of the same or another  class or classes  of stock or  securities  of the
Corporation or another entity or there is a sale of all or substantially all the
Corporation's  assets or there is a change of control  transaction not deemed to
be a  liquidation  pursuant  to Section  4.3,  then each  Series C Holder  shall
thereafter  have the right to  receive  upon  conversion  of Series C  Preferred
Stock, upon the basis and upon the terms and conditions  specified herein and in
lieu of the  shares  of  Common  Stock  immediately  theretofore  issuable  upon
conversion,  such stock,  securities  and/or  other  assets  which such Series C
Holder would have been entitled to receive in such  transaction had the Series C
Preferred Stock been converted immediately prior to such transaction, and in any
such case  appropriate  provisions  shall be made with respect to the rights and
interests  of the  holders of the Series C  Preferred  Stock to the end that the
provisions hereof (including, without limitation,  provisions for the adjustment
of the  Series C  Conversion  Price and of the  number of shares  issuable  upon
conversion of the Series C Preferred Stock) shall  thereafter be applicable,  as
nearly  as  may  be  practicable  in  relation  to  any  securities   thereafter
deliverable  upon the  exercise  hereof.  The  Corporation  shall not effect any
transaction  described in this  Section  5.6.2 unless (a) it first uses its best
efforts to give notice  thereof to each Series C Holder 30 days prior to, and in
any event gives notice thereof to each Series C Holder at least 5 days prior to,
the  record   date  of  such   merger,   consolidation,   exchange   of  shares,
recapitalization, reorganization, or other similar event (during which time each
Series C Holder  shall be  entitled  to convert its shares of Series C Preferred
Stock into Common Stock) and (b) the resulting successor or acquiring entity (if
not the  Corporation)  assumes  by written  instrument  the  obligations  of the
Corporation under this Part C, including this Section 5.6.2.

<PAGE>

                           5.5.3  Calculation of Adjustments.  In computing each
adjustment to the Conversion  Price,  the result shall be rounded to the nearest
thousandth  of a cent,  and such  adjustment  shall be made  separately  in each
instance,  and in the event the adjustment  therefrom results in a change of the
Conversion Price of less than $0.01,  then no adjustment to such then applicable
Conversion  Price shall be made,  but the amount of said  adjustment  calculated
thereby shall be carried forward to successive  occasions until such adjustments
in the aggregate equal or exceed $0.01.

         Section 6.        Redemption.

                    6.1      Corporation's Right to Redeem Generally.

                           6.1.1 General Redemption Right. The Corporation shall
have the right, in its sole discretion, to redeem, from time to time, any or all
of the  Series  C  Preferred  Stock  pursuant  to this  Section  6.1  (any  such
redemption  being referred to herein as a "General  Redemption") at a redemption
price for each such share so redeemed equal to its Redemption  Price, as defined
in Section  6.2;  provided,  that the  Corporation  shall  deliver,  at least 10
trading days advance  written  notice of such  redemption as provided in Section
6.2.2. If the  Corporation  elects to redeem some, but not all, of the shares of
Series C Preferred  Stock,  the Corporation  shall redeem a pro rata amount from
each  holder  of the  Series  C  Preferred  Stock,  and  each  such  holder  may
specifically  designate  which of its shares of such  Series C  Preferred  Stock
shall be so redeemed.

                           6.1.2   Mechanics  of  Redemption  at   Corporation's
Election.  If the  Corporation  desires to effect a redemption  pursuant to this
Section 6.1, it shall deliver prior written notice of such  redemption  ("Notice
of General  Redemption") to the holders of the Series C Preferred  Stock, at the
address and  telecopier  number of such holder  appearing  in the  Corporation's
register  for the Series C Preferred  Stock and (b) the  Transfer  Agent,  which
Notice of  General  Redemption  shall be deemed  to have  been  delivered  three
business days after the Corporation's mailing (by overnight or two day carrier),
with a copy sent by  telecopier to each such holder on the date of such mailing,
of such Notice of General  Redemption.  Such Notice of General  Redemption shall
indicate  (a) the  number of shares of Series C  Preferred  Stock that have been
selected  for  redemption,  (b) the date  which  such  redemption  is to  become
effective  (the "Date of General  Redemption"),  which  shall be a date not less
than 10 trading days  following  the date such Notice of General  Redemption  is
delivered and (c) the applicable Redemption Price.

                           6.1.3   Holder's    Right   to   Block    Redemption.
Notwithstanding  the  foregoing  provisions  of this Section 6.1,  each Series C
Holder may, by delivering a Notice of Conversion  pursuant to Section 5.3 within
seven  trading  days  following  such  holder's  receipt  of a Notice of General
Redemption, convert any or all of such holder's shares selected for redemption.

<PAGE>

                    6.2 Redemption  Price.  The redemption  price payable by the
Corporation upon redemption of any share of Series C Preferred Stock pursuant to
Section 6.1 shall be an amount  (the  "Redemption  Price")  equal to 120% of the
Original Series C Issue Price,  plus all unpaid  dividends on such share accrued
from the date of issuance to the date of such redemption.

                    6.3 Payment of Redemption Price.

                           6.3.1 Each holder of any shares of Series C Preferred
Stock  being  redeemed   under  this  Section  6  shall  send  Preferred   Stock
Certificates  evidencing  such shares to the  Corporation or its Transfer Agent,
and the Corporation  shall cause the applicable  Redemption  Price for each such
share to be paid to such holder,  in full, on the Date of  Redemption,  provided
that the Corporation  shall not be obligated to deliver the Redemption Price for
any such share until the Preferred  Stock  Certificate  evidencing such share is
delivered  to the  Corporation  or its  Transfer  Agent,  or, in the event  such
certificate has been lost, stolen,  mutilated or destroyed,  until the holder of
such share has complied with Section 5.3.2.

         Section 7. Voting Rights. Except as otherwise provided by New York law,
the  holders  of the  Series  C  Preferred  Stock  shall  have no  voting  power
whatsoever, and shall not be entitled, as such, to vote or otherwise participate
in any  proceeding  in which actions  shall be taken by the  Corporation  or the
shareholders  thereof or be entitled,  as such, to receive notice of any meeting
of the shareholders.

         To the extent that under New York law the vote of the holders of Series
C Preferred  Stock,  voting  separately  as a class,  is required to authorize a
given action of the Corporation,  the affirmative vote or consent of the holders
of at least a majority of the outstanding shares of Series C Preferred Stock, as
the case may be, represented at a duly held meeting at which a quorum is present
or by  written  consent  of a  majority  of the  outstanding  shares of Series C
Preferred  Stock, as the case may be, (except as otherwise may be required under
New York law) shall  constitute the approval of such action by the class. To the
extent that under New York law the  holders of the Series C Preferred  Stock are
entitled to vote on a matter with holders of Common  Stock,  voting  together as
one class,  each share of Series C Preferred Stock shall be entitled to a number
of votes  equal to the  number of shares of Common  Stock  into which it is then
convertible using the record date for the taking of such vote of shareholders as
the date on which a  Conversion  Price is  calculated.  Holders  of the Series C
Preferred Stock also shall be entitled to notice of all shareholder  meetings or
written  consents  with  respect to which they would be entitled to vote,  which
notice would be provided  pursuant to the  Corporation's  ByLaws and  applicable
statutes.

         Section 8.  Status of  Redeemed or  Converted  Stock.  In the event any
shares of Series C Preferred Stock shall be redeemed or converted, the shares so
converted  or  redeemed  shall  be  canceled,  shall  return  to the  status  of
authorized but unissued Preferred Stock of no designated series and shall not be
issuable by the Corporation as Series C Preferred Stock.

Shares at least 20 days  prior to the  Dividend  Date.  Dividends  to be paid in

in Section 3(b)),  or an event that with the passage of time would  constitute a
Triggering Event if not cured, has occurred and is continuing on the date of the
Company's  Dividend  Election Notice or on the Dividend Date,  unless  otherwise

such Dividend or (y) the Registration  Statement (as defined in the Registration
Rights  Agreement  (as defined  below)) is not  effective  and available for the
resale of all of the  Registrable  Securities  (as  defined in the  Registration

and unpaid  Dividends  which are not paid within five (5) Business  Days of such

      Rate"):

                                Conversion Price

                        Mechanics of  Conversion.  The  conversion  of Preferred
            Shares shall be conducted in the following manner:

                              Holder's   Delivery   Requirements.   To   convert
      Preferred  Shares into shares of Common Stock on any date (the "Conversion
      Date"),  the holder  thereof shall (A) transmit by facsimile (or otherwise
      deliver),  for  receipt on or prior to 11:59  p.m.,  New York City Time on
      such date, a copy of a fully executed notice of conversion in the form set
      forth in Section 21 (the  "Conversion  Notice") to the Company with a copy
      thereof to the Company's  designated transfer agent (the "Transfer Agent")
      and (B) if required by Section  2(d)(viii),  surrender to a common carrier
      for delivery to the Transfer Agent as soon as  practicable  following such
      date the original  certificates  representing  the Preferred  Shares being
      converted (or an  indemnification  undertaking with respect to such shares
      in the case of their loss,  theft or destruction)  (the  "Preferred  Stock
      Certificates").  Such holder  shall use its best efforts to send a copy of
      each   Conversion   Notice  within  one  (1)  Business  Day  of  facsimile
      transmission  of  such  Conversion  Notice  via  e-mail  to  the  Company;
      provided,  however,  that  the  failure  of  any  holder  to  satisfy  its
      obligations  under this sentence shall not effect the  Conversion  Date or
      the obligations of the Company for any conversion of Preferred Shares.

                              Company's Response. Upon receipt by the Company of
      a copy of a Conversion Notice, the Company (1) shall immediately send, via
      facsimile,  a confirmation  of receipt of such  Conversion  Notice to such
      holder and the Transfer  Agent,  which  confirmation  shall  constitute an
      instruction  to the Transfer  Agent to process such  Conversion  Notice in
      accordance  with the terms herein and (2) on or before the second Business
      Day following the date of receipt by the Company of such Conversion Notice
      (the  "Share  Delivery  Date"),  (A) issue and  deliver to the  address as
      specified in the Conversion Notice, a certificate,  registered in the name
      of the holder or its designee, for the number of shares of Common Stock to
      which the holder shall be entitled,  or (B) provided the Transfer Agent is
      participating  in The  Depository  Trust  Company  ("DTC") Fast  Automated
      Securities Transfer Program,  upon the request of the holder,  credit such
      aggregate  number of shares of Common  Stock to which the holder  shall be
      entitled  to the  holder's  or its  designee's  balance  account  with DTC
      through its Deposit  Withdrawal Agent Commission  system. If the number of
      Preferred  Shares  represented  by  the  Preferred  Stock   Certificate(s)
      submitted for  conversion  is greater than the number of Preferred  Shares
      being converted, then the Transfer Agent shall, as soon as practicable and
      in no event later than three  Business Days after receipt of the Preferred
      Stock  Certificate(s) (the

<PAGE>

      "Preferred Stock Delivery Date") and at its own expense, issue and deliver
      to the holder a new Preferred Stock Certificate representing the number of
      Preferred Shares not converted.

                              Dispute Resolution. In the case of a dispute as to
      the determination of the Market Price or the arithmetic calculation of the
      Conversion Rate, the Company shall instruct the Transfer Agent to issue to
      the holder the number of shares of Common  Stock that is not  disputed and
      shall submit the disputed determinations or arithmetic calculations to the
      holder  via  facsimile  by 11:59 New York City  Time on the  Business  Day
      immediately  following  the date of  receipt of such  holder's  Conversion
      Notice.  If such  holder  and the  Company  are  unable to agree  upon the
      determination  of  the  Market  Price  or  arithmetic  calculation  of the
      Conversion Rate within one (1) Business Day of such disputed determination
      or arithmetic  calculation being submitted to the holder, then the Company
      shall within one (1) Business  Day submit via  facsimile  (A) the disputed
      determination of the Market Price to an independent,  reputable investment
      bank  selected by the Company and approved by the holders of a majority of
      the  Preferred  Shares then  outstanding  or (B) the  disputed  arithmetic
      calculation of the Conversion Rate to the Company's  independent,  outside
      accountant. The Company shall cause the investment bank or the accountant,
      as the case may be, to perform  the  determinations  or  calculations  and
      notify the  Company  and the holder of the  results no later than five (5)
      Business  Days from the time it receives  the disputed  determinations  or
      calculations.  Such  investment  bank's or accountant's  determination  or
      calculation,  as the case may be, shall be binding upon all parties absent
      error.

                              Record Holder.  The person or persons  entitled to
      receive the shares of Common Stock issuable upon a conversion of Preferred
      Shares shall be treated for all  purposes as the record  holder or holders
      of such shares of Common Stock on the Conversion Date.

                              Company's Failure to Timely Convert.

                              (A) Cash Damages. If within four (4) Business Days
      after the Company's  receipt of the facsimile copy of a Conversion  Notice
      the Company shall fail to issue a  certificate  to a holder or credit such
      holder's balance account with DTC for the number of shares of Common Stock
      to which  such  holder  is  entitled  upon  such  holder's  conversion  of
      Preferred   Shares  or  to  issue  a  new  Preferred   Stock   Certificate
      representing  the  number  of  Preferred  Shares to which  such  holder is
      entitled pursuant to Section 2(d)(ii),  in addition to all other available
      remedies  which such holder may pursue  hereunder and under the Securities
      Purchase  Agreement  (including  indemnification  pursuant  to  Section  8
      thereof), the Company shall pay additional damages to such holder for each
      date after the Share Delivery Date such  conversion is not timely effected
      and/or each date after the Preferred  Stock  Delivery Date such  Preferred
      Stock  Certificate  is not delivered in an amount equal to 0.5% of the sum
      of (a) the product of (I) the number of shares of Common  Stock not issued
      to the  holder on or prior to the Share  Delivery  Date and to which  such
      holder is entitled

<PAGE>

      and (II) the Closing Bid Price of the Common  Stock on the Share  Delivery
      Date,  and (b) in the event the  Company has failed to deliver a Preferred
      Stock  Certificate  to the  holder  on or  prior  to the  Preferred  Stock
      Delivery  Date,  the  product of (y) the number of shares of Common  Stock
      issuable  upon  conversion  of the Preferred  Shares  represented  by such
      Preferred Stock  Certificate,  as of the Preferred Stock Delivery Date and
      (z) the  Closing  Bid Price of the  Common  Stock on the  Preferred  Stock
      Delivery  Date.  If the Company  fails to pay the  additional  damages set
      forth  in this  Section  2(d)(v)  within  five  Business  Days of the date
      incurred,  then the holder  entitled to such payments shall have the right
      at any  time,  so  long as the  Company  continues  to  fail to make  such
      payments,  to require the Company,  upon written  notice,  to  immediately
      issue, in lieu of such cash damages,  the number of shares of Common Stock
      equal to the quotient of (X) the aggregate  amount of the damages payments
      described  herein  divided by (Y) the  Conversion  Price in effect on such
      Conversion Date as specified by the holder in the Conversion Notice.

                              (B)  Void   Conversion   Notice;   Adjustment   to
      Conversion  Price.  If for any reason a holder has not received all of the
      shares of Common  Stock prior to the tenth  (10th)  Business Day after the
      Share Delivery Date with respect to a conversion of Preferred Shares, then
      the  holder,  upon  written  notice  to the  Company,  with a copy  to the
      Transfer Agent, may void its Conversion Notice with respect to, and retain
      or have returned,  as the case may be, any Preferred  Shares that have not
      been converted pursuant to such holder's Conversion Notice;  provided that
      the voiding of a holder's Conversion Notice shall not effect the Company's
      obligations  to make any payments  which have accrued prior to the date of
      such notice pursuant to Section 2(d)(v)(A) or otherwise.  Thereafter,  the
      Conversion  Price of any  Preferred  Shares  returned  or  retained by the
      holder for  failure to timely  convert  shall be adjusted to the lesser of
      (I) the  Conversion  Price as in effect  on the date on which  the  holder
      voided the Conversion  Notice and (II) the lowest Closing Bid Price during
      the period  beginning on the  Conversion  Date and ending on the date such
      holder voided the Conversion Notice.

                              (C) Redemption. If for any reason a holder has not
      received  all of the  shares of  Common  Stock  prior to the tenth  (10th)
      Business Day after the Share Delivery Date with respect to a conversion of
      Preferred Shares (a "Conversion  Failure"),  then the holder, upon written
      notice to the Company,  may require that the Company  redeem all Preferred
      Shares held by such holder,  including  the  Preferred  Shares  previously
      submitted  for  conversion  and with  respect to which the Company has not
      delivered shares of Common Stock, in accordance with Section 3.

                              Pro Rata Conversion and  Redemption.  In the event
      the  Company  receives a  Conversion  Notice  from more than one holder of
      Preferred  Shares for the same Conversion Date and the Company can convert
      some,  but not all, of such  Preferred  Shares,  the Company shall convert
      from each holder of Preferred  Shares  electing to have  Preferred  Shares
      converted at such time a pro rata amount of such holder's Preferred Shares
      submitted for conversion based on the number of Preferred Shares submitted
      for  conversion  on such date by such  holder  relative  to the

<PAGE>

      number of Preferred Shares submitted for conversion on such date.

                              Mandatory Conversion or Redemption at Maturity. If
      any Preferred  Shares remain  outstanding on the Maturity  Date,  then all
      such  Preferred  Shares,  at the  Company's  option,  either  (i) shall be
      converted at 110% of the Conversion  Rate as of such date and otherwise as
      if the holders of such Preferred Shares had given the Conversion Notice on
      the Maturity Date (a "Maturity Date Mandatory Conversion"),  or (ii) shall
      be redeemed as of such date for an amount in cash per Preferred Share (the
      "Maturity Date Redemption Price") equal to the Liquidation  Preference (as
      defined in Section  10) (a  "Maturity  Date  Mandatory  Redemption").  The
      Company  shall  be  deemed  to have  elected  a  Maturity  Date  Mandatory
      Redemption  unless it delivers  written notice to each holder of Preferred
      Shares  at least  20  Business  Days  prior  to the  Maturity  Date of its
      election to effect a Maturity Date  Mandatory  Conversion.  If the Company
      elects a Maturity Date Mandatory Redemption, then on the Maturity Date the
      Company shall pay to each holder of Preferred  Shares  outstanding  on the
      Maturity Date, by wire transfer of immediately  available funds, an amount
      per Preferred  Share equal to the Maturity Date  Redemption  Price. If the
      Company  elects a Maturity  Date  Mandatory  Redemption  and shall fail to
      redeem all of the  Preferred  Shares  outstanding  on the Maturity Date by
      payment of the Maturity  Date  Redemption  Price,  then in addition to any
      remedy such holder of  Preferred  Shares may have under these  Articles of
      Amendment,  the Securities  Purchase Agreement and the Registration Rights
      Agreement,  (X) the applicable  Maturity Date Redemption  Price payable in
      respect of such  unredeemed  Preferred  Shares shall bear  interest at the
      rate of 1.5% per month,  prorated for partial months,  until paid in full,
      and (Y) any holder of  Preferred  Shares  shall have the option to require
      the Company to convert any or all of such holder's  Preferred  Shares that
      the Company  elected to redeem under this Section  2(d)(vii) and for which
      the Maturity Date Redemption  Price  (together with any interest  thereon)
      has not been paid into the number of shares of Common  Stock  such  holder
      would have received if such holder had given a Conversion  Notice for such
      Preferred  Shares on the Maturity  Date. On the Maturity Date, all holders
      of Preferred Shares shall surrender all Preferred Stock Certificates, duly
      endorsed for  cancellation,  to the Company or the Transfer  Agent. If the
      Company has elected a Maturity Date Mandatory  Conversion or has failed to
      pay the Maturity  Date  Redemption  Price in a timely  manner as described
      above,  then the Maturity Date shall be extended for any Preferred  Shares
      for as long as (A) the conversion of such  Preferred  Shares would violate
      the  provisions  of Section 5, (B) a Triggering  Event shall have occurred
      and be  continuing,  or (C) an event shall have occurred and be continuing
      which with the passage of time and the  failure to cure would  result in a
      Triggering Event.

                              Book-Entry.   Notwithstanding   anything   to  the
      contrary  set  forth  herein,  upon  conversion  of  Preferred  Shares  in
      accordance with the terms hereof, the holder thereof shall not be required
      to physically surrender the certificate  representing the Preferred Shares
      to the Company unless the full number of Preferred  Shares  represented by
      the  certificate  are being  converted.  The holder and the Company  shall
      maintain  records showing the number of Preferred  Shares so

<PAGE>

      converted  and the  dates  of such  conversions  or shall  use such  other
      method,  reasonably  satisfactory to the holder and the Company, so as not
      to  require  physical  surrender  of  the  certificate   representing  the
      Preferred Shares upon each such conversion. In the event of any dispute or
      discrepancy,  such  records  of  the  Company  shall  be  controlling  and
      determinative  in the  absence  of  manifest  error.  Notwithstanding  the
      foregoing,  if Preferred Shares represented by a certificate are converted
      as aforesaid, the holder may not transfer the certificate representing the
      Preferred  Shares  unless  the  holder  first  physically  surrenders  the
      certificate  representing the Preferred  Shares to the Company,  whereupon
      the Company will forthwith  issue and deliver upon the order of the holder
      a new  certificate  of like tenor,  registered  as the holder may request,
      representing  in the aggregate the  remaining  number of Preferred  Shares
      represented  by  such  certificate.   The  holder  and  any  assignee,  by
      acceptance of a certificate,  acknowledge and agree that, by reason of the
      provisions  of  this  paragraph,  following  conversion  of any  Preferred
      Shares, the number of Preferred Shares represented by such certificate may
      be less than the number of Preferred  Shares  stated of the face  thereof.
      Each certificate for Preferred Shares shall bear the following legend:

               ANY  TRANSFEREE  OF THIS  CERTIFICATE  SHOULD  CAREFULLY
               REVIEW  THE  TERMS  OF  THE  COMPANY'S   CERTIFICATE  OF
               AMENDMENT,  PREFERENCES  AND  RIGHTS  OF  THE  PREFERRED
               SHARES   REPRESENTED  BY  THIS  CERTIFICATE,   INCLUDING
               SECTION  2(d)(viii)  THEREOF.  THE  NUMBER OF  PREFERRED
               SHARES  REPRESENTED BY THIS CERTIFICATE MAY BE LESS THAN
               THE NUMBER OF PREFERRED SHARES STATED ON THE FACE HEREOF
               PURSUANT TO SECTION  2(d)(viii)  OF THE  CERTIFICATE  OF
               AMENDMENT, PREFERENCES AND RIGHTS.

                              Taxes.  The  Company  shall  pay any and all taxes
             that may be payable  with  respect to the  issuance and delivery of
             Common Stock upon the conversion of Preferred Shares.

                              Adjustments  to Conversion  Price.  The Conversion
             Price will  be subject to adjustment  from time to time as provided
             in this Section 2(f).

                              (i) Adjustment of the Fixed  Conversion Price upon
      Issuance of Common Stock. If and whenever on or after the date of issuance
      of the Preferred  Shares,  the Company  issues or sells,  or in accordance
      with this  Section  2(f) is deemed to have  issued or sold,  any shares of
      Common  Stock  (including  the  issuance or sale of shares of Common Stock
      owned or held by or for the account of the Company,  but excluding  shares
      of  Common  Stock  deemed  to  have  been  issued  by the  Company  (I) in
      connection with an Approved Stock Plan (as defined  below),  (II) upon the
      conversion or exercise of Convertible  Securities which are outstanding as
      of the  Initial  Issuance  Date and listed on  Schedule  3(c)(iii)  to the
      Securities Purchase

<PAGE>

      Agreement, provided that the terms of such Convertible Securities have not
      been altered,  amended or revised since the Initial Issuance Date or (III)
      upon  conversion of the Preferred  Shares) for a  consideration  per share
      less than a price (the  "Applicable  Price") equal to the Fixed Conversion
      Price in effect  immediately  prior to such time, then  immediately  after
      such issue or sale,  the Fixed  Conversion  Price then in effect  shall be
      reduced to an amount equal to such  consideration  per share. For purposes
      of  determining  the adjusted  Fixed  Conversion  Price under this Section
      2(f)(i), the following shall be applicable:

                              (A)  Issuance  of  Options.  If the Company in any
      manner  grants or sells any  Options  and the  lowest  price per share for
      which one share of Common Stock is issuable  upon the exercise of any such
      Option  or upon  conversion  or  exchange  of any  Convertible  Securities
      issuable upon exercise of such Option is less than the  Applicable  Price,
      then such share of Common Stock shall be deemed to be  outstanding  and to
      have been  issued and sold by the  Company at the time of the  granting or
      sale of such Option for such price per share. For purposes of this Section
      2(f)(i)(A),  the  "lowest  price  per  share for which one share of Common
      Stock is issuable upon the exercise of any such Option or upon  conversion
      or exchange of any Convertible  Securities  issuable upon exercise of such
      Option" shall be equal to the sum of the lowest  amounts of  consideration
      (if any)  received or  receivable  by the Company  with respect to any one
      share of Common Stock upon  granting or sale of the Option,  upon exercise
      of the Option and upon conversion or exchange of any Convertible  Security
      issuable upon exercise of such Option. No further  adjustment of the Fixed
      Conversion  Price  shall be made upon the actual  issuance  of such Common
      Stock or of such Convertible  Securities upon the exercise of such Options
      or upon the  actual  issuance  of such  Common  Stock upon  conversion  or
      exchange of such Convertible Securities.

                              (B)  Issuance of  Convertible  Securities.  If the
      Company in any manner issues or sells any  Convertible  Securities and the
      lowest  price per share  for which one share of Common  Stock is  issuable
      upon such  conversion  or  exchange  thereof  is less than the  Applicable
      Price,  then such share of Common Stock shall be deemed to be  outstanding
      and to have  been  issued  and  sold  by the  Company  at the  time of the
      issuance of sale of such Convertible  Securities for such price per share.
      For the  purposes  of this  Section  2(f)(i)(B),  the "price per share for
      which one share of  Common  Stock is  issuable  upon  such  conversion  or
      exchange" shall be equal to the sum of the lowest amounts of consideration
      (if any)  received or  receivable  by the Company  with respect to any one
      share  of  Common  Stock  upon  the  issuance  or sale of the  Convertible
      Security and upon the conversion or exchange of such Convertible Security.
      No further adjustment of the Fixed Conversion Price shall be made upon the
      actual  issuance of such Common Stock upon  conversion or exchange of such
      Convertible Securities,  and if any such issue or sale of such Convertible
      Securities  is made upon  exercise of any Options for which  adjustment of
      the Fixed  Conversion  Price had been or are to be made  pursuant to other
      provisions  of this Section  2(f)(i),  no further  adjustment of the Fixed
      Conversion Price shall be made by reason of such issue or sale.

<PAGE>

                              (C) Change in Option Price or Rate of  Conversion.
      If  the  purchase  price  provided  for  in any  Options,  the  additional
      consideration,  if any, payable upon the issue,  conversion or exchange of
      any  Convertible  Securities,   or  the  rate  at  which  any  Convertible
      Securities are convertible  into or exchangeable  for Common Stock changes
      at any  time,  the  Fixed  Conversion  Price in effect at the time of such
      change  shall be adjusted to the Fixed  Conversion  Price which would have
      been in effect at such time had such  Options  or  Convertible  Securities
      provided for such changed  purchase  price,  additional  consideration  or
      changed  conversion  rate,  as the  case  may be,  at the  time  initially
      granted,  issued or sold. For purposes of this Section 2(f)(i)(C),  if the
      terms of any Option or Convertible Security that was outstanding as of the
      date of  issuance  of the  Preferred  Shares  are  changed  in the  manner
      described  in the  immediately  preceding  sentence,  then such  Option or
      Convertible  Security and the Common Stock deemed  issuable upon exercise,
      conversion  or exchange  thereof shall be deemed to have been issued as of
      the date of such change.  No adjustment  shall be made if such  adjustment
      would result in an increase of the Fixed Conversion Price then in effect.

                              (D) Calculation of Consideration Received. In case
      any  Option  is  issued  in  connection  with  the  issue or sale of other
      securities of the Company,  together comprising one integrated transaction
      in which no specific  consideration  is  allocated  to such Options by the
      parties  thereto,  the  Options  will be deemed to have been  issued for a
      consideration of $0.01, unless the Board of Directors of the Company shall
      have made a good faith allocation of the  consideration  received for such
      Option and such other securities,  in which case the Option and such other
      securities will be deemed to be issued for the  consideration as allocated
      by such Board. If any Common Stock, Options or Convertible  Securities are
      issued  or sold or  deemed  to have  been  issued  or sold for  cash,  the
      consideration  received  therefor  will be  deemed  to be the  net  amount
      received  by  the  Company  therefor.  If any  Common  Stock,  Options  or
      Convertible  Securities are issued or sold for a consideration  other than
      cash,  the amount of the  consideration  other than cash  received  by the
      Company  will be the fair value of such  consideration,  except where such
      consideration  consists  of  securities,  in  which  case  the  amount  of
      consideration  received by the  Company  will be the average of the Market
      Price of such  securities  on the date of  receipt.  If any Common  Stock,
      Options  or  Convertible  Securities  are  issued  to  the  owners  of the
      non-surviving entity in connection with any merger in which the Company is
      the surviving entity, the amount of consideration  therefor will be deemed
      to be the fair value of such portion of the net assets and business of the
      non-surviving  entity as is attributable to such Common Stock,  Options or
      Convertible  Securities,  as the  case  may  be.  The  fair  value  of any
      consideration other than cash or securities will be determined by the good
      faith  determination of the Company's Board of Directors.  If such parties
      are unable to reach  agreement  within 10 days after the  occurrence of an
      event requiring valuation (the "Valuation Event"),  the fair value of such
      consideration will be determined within five Business Days after the tenth
      (10th) day  following  the Valuation  Event by an  independent,  reputable
      appraiser jointly selected by the Company and the holders of a majority of
      the Preferred Shares then outstanding. The determination of such

<PAGE>

      appraiser  shall be deemed binding upon all parties absent  manifest error
      and the fees and expenses of such appraiser shall be borne by the Company.

                              (E) Record Date.  If the Company takes a record of
      the  holders  of Common  Stock for the  purpose of  entitling  them (1) to
      receive a dividend or other distribution  payable in Common Stock, Options
      or in  Convertible  Securities or (2) to subscribe for or purchase  Common
      Stock,  Options or Convertible  Securities,  then such record date will be
      deemed to be the date of the issue or sale of the  shares of Common  Stock
      deemed to have been issued or sold upon the  declaration  of such dividend
      or the making of such other  distribution  or the date of the  granting of
      such right of subscription or purchase, as the case may be.

                              (F)  Certain  Definitions.  For  purposes  of this
      Section  2(f)(i),  the following  terms have the  respective  meanings set
      forth below:

                                    (I)  "Approved  Stock  Plan"  shall mean any
      employee benefit plan which has been approved by the Board of Directors of
      the Company,  pursuant to which the Company's  securities may be issued to
      any employee,  officer,  director or consultants for services  provided to
      the Company.

                                    (II) "Options" means any rights, warrants or
      options  to  subscribe  for  or  purchase   Common  Stock  or  Convertible
      Securities.

                                    (III)  "Convertible  Securities"  means  any
      stock  or  securities   (other  than   Options)   directly  or  indirectly
      convertible into or exchangeable for Common Stock.

                        (ii) Adjustment of the Conversion Price upon Subdivision
      or Combination of Common Stock.  If the Company at any time subdivides (by
      any stock split,  stock  dividend,  recapitalization  or otherwise) one or
      more  classes  of its  outstanding  shares of Common  Stock into a greater
      number of shares, the Conversion Price in effect immediately prior to such
      subdivision will be  proportionately  reduced.  If the Company at any time
      combines (by  combination,  reverse stock split or otherwise)  one or more
      classes of its outstanding shares of Common Stock into a smaller number of
      shares,   the  Conversion  Price  in  effect  immediately  prior  to  such
      combination will be proportionately increased.

                        (iii)  Holder's Right of  Alternative  Conversion  Price
      Following Issuance of Convertible Securities. If the Company in any manner
      issues  or  sells  Convertible  Securities  that are  convertible  into or
      exchangeable  for Common  Stock at a price  which may vary with the market
      price of the  Common  Stock,  including  by way of  periodic  reset to the
      Conversion  Price (the  formulation  for such variable  price being herein
      referred to as, the "Variable  Price"),  the Company shall provide written
      notice  thereof via facsimile and overnight  courier to each holder of the
      Preferred  Shares  ("Variable  Notice")  on the date of  issuance  of such
      Convertible  Securities.  From and after the date the  Company  issues any
      such  Convertible  Securities with a

<PAGE>

      Variable Price, a holder of Preferred Shares shall have the right, but not
      the  obligation,  in its sole  discretion to substitute the Variable Price
      for the Floating  Conversion Price upon conversion of any Preferred Shares
      by designating in the Conversion  Notice delivered upon conversion of such
      Preferred Shares that solely for purposes of such conversion the holder is
      relying on the Variable  Price rather than the Floating  Conversion  Price
      then in effect.  A  holder's  election  to rely on a Variable  Price for a
      particular conversion of Preferred Shares shall not obligate the holder to
      rely on a Variable Price for any future conversions of Preferred Shares.

                        (iv)  Adjustment  of the  Conversion  Price  Upon  Major
      Corporate Event Announcement.  In the event (A) the Company makes a public
      announcement  that it intends to consolidate or merge with or into another
      Person or engage in a  business  combination  involving  the  issuance  or
      exchange of more than 30% of the Company's  outstanding  Common Stock, (B)
      the  Company  makes  a  public  announcement  that it  intends  to sell or
      transfer all or  substantially  all of the  Company's  assets,  or (C) any
      Person  (including the Company) publicly  announces a purchase,  tender or
      exchange offer for more than 30% of the Company's outstanding Common Stock
      (the  transactions  described  in  clauses  (A),  (B)  and (C)  above  are
      hereinafter  referred to as "Major  Corporate  Events" and the date of the
      announcement referred to in clause (A), (B) or (C) is hereinafter referred
      to as the "Announcement Date"), then the Conversion Price shall, effective
      upon the  Announcement  Date and  continuing  through  and  including  the
      Adjusted Conversion Price Termination Date (as defined below), be equal to
      the Conversion  Price which would have been applicable for a conversion by
      the  holder  on  the  Announcement  Date.  From  and  after  the  Adjusted
      Conversion  Price   Termination   Date,  the  Conversion  Price  shall  be
      determined as set forth in Section 2(c).  For purposes  hereof,  "Adjusted
      Conversion  Price  Termination  Date"  shall  mean,  with  respect  to any
      proposed  Major  Corporate  Event  for  which  a  public  announcement  as
      contemplated  by this Section  2(f)(iv) has been made, the date upon which
      the Company or other Person (in the case of clause (C) above)  consummates
      or publicly announces the termination or abandonment of the proposed Major
      Corporate Event which was the subject of the previous public announcement.

                        (v)  Other  Events.  If any  event  occurs  of the  type
      contemplated  by the  provisions  of this Section  2(f) but not  expressly
      provided  for by  such  provisions  (including,  without  limitation,  the
      granting  of stock  appreciation  rights,  phantom  stock  rights or other
      rights with equity  features),  then the Company's Board of Directors will
      make an appropriate  adjustment in the  Conversion  Price so as to protect
      the rights of the holders of the Preferred  Shares;  provided that no such
      adjustment  will  increase the  Conversion  Price as otherwise  determined
      pursuant to this Section 2(f).

                        (vi) Notices.

                              (A)   Immediately   upon  any  adjustment  of  the
      Conversion  Price,  the Company will give written  notice  thereof to each
      holder of  Preferred  Shares,  setting  forth in  reasonable  detail,  and
      certifying, the calculation of

<PAGE>

      such adjustment.

                              (B) The Company will give  written  notice to each
      holder of Preferred  Shares at least five (5)  Business  Days prior to the
      date on which the  Company  closes  its  books or takes a record  (I) with
      respect to any dividend or distribution  upon the Common Stock,  (II) with
      respect to any pro rata  subscription  offer to holders of Common Stock or
      (III) for  determining  rights to vote with respect to any Organic Change,
      dissolution or liquidation,  provided that such information  shall be made
      known to the public  prior to or in  conjunction  with such  notice  being
      provided to such holder.

                              (C) The Company will also give  written  notice to
      each holder of Preferred  Shares at least ten (10)  Business Days prior to
      the date on which any Organic Change, dissolution or liquidation will take
      place,  provided that such  information  shall be made known to the public
      prior to or in conjunction with such notice being provided to such holder.

                        (g) Conversion  Restrictions.  Subject to the exceptions
      described  below,  without the prior  consent of the  Company,  the Buyers
      shall not be entitled to submit a Conversion  Notice for the conversion of
      any of the  Preferred  Shares  during the period  beginning on the Initial
      Closing Date and ending on December 31, 1999.  During the period beginning
      on and  including  January 1, 2000 and ending on January  31,  2000,  each
      Purchaser  (as  defined  in  Section  14)  may  convert  up to  25% of the
      Preferred Shares issued to such Purchaser.  During the period beginning on
      and  including  January  1, 2000 and ending on  February  29,  2000,  each
      Purchaser  may convert up to 50% of the  Preferred  Shares  issued to such
      Purchaser.  During the period  beginning on and including  January 1, 2000
      and ending on March 31, 2000,  each Purchaser may convert up to 75% of the
      Preferred  Shares issued to such Purchaser.  From and after April 1, 2000,
      each  Purchaser  may convert all of the  Preferred  Shares  issued to such
      Purchaser.  Notwithstanding the foregoing, the conversion restrictions set
      forth above shall not apply: (a) on and after any date on which the Common
      Stock is not listed,  quoted or  reported on The New York Stock  Exchange,
      Inc., The American Stock Exchange,  Inc., the Nasdaq National Market,  The
      Nasdaq SmallCap Market or the OTCBB or has been delisted or suspended from
      trading on any such exchange or quotation or reporting system, or any such
      delisting or suspension is threatened or pending  either (I) in writing by
      such exchanges or quotation or reporting  systems or (II) by falling below
      the  minimum  listing  maintenance   requirements  of  such  exchanges  or
      quotation  or reporting  systems;  (b) on or after any date on which there
      shall have occurred an event  constituting a Change of Control (as defined
      below), an announcement of a pending Change of Control, a Triggering Event
      (as  defined  below) or an event that with the passage of time and without
      being cured would constitute a Triggering  Event; (c) on or after any date
      on which the  Company  issues or sells or is deemed to have issued or sold
      Convertible  Securities  that  are  convertible  into  or  exercisable  or
      exchangeable  for Common  Stock at a Variable  Price;  (d) on or after the
      date the Company delivers a Notice of Redemption at Company's Election (as
      defined  in Section  6); (e) on or after any date on which the  arithmetic

<PAGE>

      average of the  Closing  Bid  Prices of the Common  Stock for the five (5)
      consecutive trading days immediately  preceding such date is less than 90%
      of the Closing Bid Price of the Common Stock on the Initial  Issuance Date
      (subject  to  adjustment  for  stock  splits,   stock   dividends,   stock
      combinations and other similar  transactions);  or (f) with respect to any
      conversion of Preferred  Shares,  at a price equal to the Fixed Conversion
      Price then in effect.

                        (h) Adjustment of Conversion  Restrictions upon Issuance
      of  Convertible  Securities.  If the Company in any manner issues or sells
      Convertible  Securities  that are  convertible  into Common  Stock and are
      subject to (i) restrictions on the amount of shares that can be converted,
      or (ii) no restrictions on the amount of shares that can be converted (the
      restriction on conversions or lack thereof being herein referred to as the
      "Conversion   Restriction"),   and  such  Conversion  Restriction  is  not
      formulated  using the same time  periods and  percentages  used in Section
      2(g),  then the Company shall provide written notice thereof via facsimile
      and overnight courier to each holder of the Preferred Shares  ("Conversion
      Restriction   Notice")  on  the  date  of  issuance  of  such  Convertible
      Securities.  If the  holders of  Preferred  Shares  representing  at least
      two-thirds  (2/3) of the Preferred  Shares then  outstanding  which remain
      subject to the  restrictions  in Section 2(g) provide  written  notice via
      facsimile  and overnight  courier (the  "Conversion  Restriction  Election
      Notice")  to the  Company  within five (5)  Business  Days of  receiving a
      Conversion  Restriction  Notice  that such  holders  desire to replace the
      conversion  restrictions set forth in Section 2(g) then in effect with the
      Conversion  Restriction  described in such Conversion  Restriction Notice,
      then from and after the date of the  Company's  receipt of the  Conversion
      Restriction  Election  Notice  the  conversion  restrictions  set forth in
      Section  2(g)   automatically   will  be  replaced  with  the   Conversion
      Restrictions  (together  with such  modifications  to this  Certificate of
      Amendment  as may be required to give full effect to the  substitution  of
      the Conversion  Restrictions for the conversion  restrictions set forth in
      Section 2(g)). A holder's  delivery of a Conversion  Restriction  Election
      Notice shall serve as the consent  required to amend this  Certificate  of
      Amendment pursuant to Section 15 below.

                  Section 3. Redemption at Option of Holders.

                        Redemption  Option Upon Triggering Event. In addition to
            all other  rights  of the  holders  of  Preferred  Shares  contained
            herein,  after a Triggering Event (as defined below), each holder of
            Preferred Shares shall have the right, at such holder's  option,  to
            require  the  Company to redeem  all or a portion  of such  holder's
            Preferred Shares at a price per Preferred Share equal to the greater
            of (i) 125% of the  Liquidation  Preference  and (ii) the product of
            (A) the  Conversion  Rate in  effect  at  such  time as such  holder
            delivers  a Notice of  Redemption  at  Option  of Buyer (as  defined
            below) and (B) the  arithmetic  average of the Closing Bid Prices of
            the  Common  Stock  on  the  five  (5)   consecutive   trading  days
            immediately  preceding such Triggering  Event on which the Principal
            Market,  or the market or  exchange  where the Common  Stock is then
            traded, is open for trading ("Redemption Price").

<PAGE>

                        "Triggering Event". A "Triggering Event" shall be deemed
            to have occurred at such time as any of the following events:

                              the   failure  of  the   applicable   Registration
      Statement to be declared effective by the SEC on or prior to the date that
      is 45 days after the applicable  Effectiveness Deadline (as defined in the
      Registration Rights Agreement);

                              while the Registration Statement is required to be
      maintained  effective  pursuant  to the terms of the  Registration  Rights
      Agreement,  the effectiveness of the Registration Statement lapses for any
      reason (including, without limitation, the issuance of a stop order) or is
      unavailable  to the holder of the Preferred  Shares for sale of all of the
      Registrable  Securities (as defined in the Registration  Rights Agreement)
      in accordance with the terms of the  Registration  Rights  Agreement,  and
      such lapse or  unavailability  continues for a period of five  consecutive
      trading  days,  provided  that such five day period shall be extended to a
      total of 10  consecutive  trading days in the event that the Company makes
      an  acquisition  which is required to be reported under Item 2 of Form 8-K
      and for which pro forma  financial  information is required to be reported
      pursuant to Article 11 of Regulation S-X promulgated under the 1933 Act.

                              the  suspension  from  trading  or  failure of the
      Common  Stock to be listed,  quoted or  reported  on The  Nasdaq  SmallCap
      Market, The Nasdaq National Market, The New York Stock Exchange, Inc., The
      American  Stock  Exchange,  Inc.  or  the  OTCBB  for  a  period  of  five
      consecutive  trading days or for more than an aggregate of 10 trading days
      in any 365-day period;

                              the  Company's or the Transfer  Agent's  notice to
      any holder of Preferred Shares,  including by way of public  announcement,
      at any time, of its intention not to comply with a request for  conversion
      of any  Preferred  Shares into shares of Common  Stock that is tendered in
      accordance with the provisions of this Certificate of Amendment;

                              a  Conversion   Failure  (as  defined  in  Section
      2(d)(v)(C);

                              upon the Company's receipt of a Conversion Notice,
      the Company  shall not be  obligated  to issue shares of Common Stock upon
      such conversion due to the provisions of Section 14; or

                              the Company breaches any representation, warranty,
      covenant or other term or condition of the Securities  Purchase Agreement,
      the  Registration  Rights  Agreement,  the Warrants,  this  Certificate of
      Amendment  or  any  other  agreement,   document,   certificate  or  other
      instrument  delivered in  connection  with the  transactions  contemplated
      thereby and hereby, except to the extent that such breach would not have a
      Material  Adverse  Effect (as  defined in Section  3(a) of the

<PAGE>

      Securities  Purchase  Agreement) and except,  in the case of a breach of a
      covenant which is curable,  only if such breach  continues for a period of
      at least 10 days after the  earlier  of (I) the date on which the  Company
      knowledge  of such  breach or (II) the date a holder of  Preferred  Shares
      gives written notification to the Company regarding such breach.

                        Mechanics of Redemption  at Option of Buyer.  Within one
            (1) Business Day after the  occurrence  of a Triggering  Event,  the
            Company  shall  deliver  written  notice  thereof via  facsimile and
            overnight  courier ("Notice of Triggering  Event") to each holder of
            Preferred  Shares.  At any time  after  the  earlier  of a  holder's
            receipt of a Notice of  Triggering  Event and such  holder  becoming
            aware of a Triggering  Event,  any holder of  Preferred  Shares then
            outstanding  may require the Company to redeem all of the  Preferred
            Shares by  delivering  written  notice  thereof  via  facsimile  and
            overnight courier ("Notice of Redemption at Option of Buyer") to the
            Company,  which  Notice  of  Redemption  at  Option  of Buyer  shall
            indicate the number of Preferred Shares that such holder is electing
            to redeem.

                        Payment of Redemption  Price. Upon the Company's receipt
            of a Notice(s) of  Redemption  at Option of Buyer from any holder of
            Preferred Shares,  the Company shall immediately  notify each holder
            of Preferred  Shares by facsimile of the  Company's  receipt of such
            notices and each holder which has sent such a notice shall  promptly
            submit  to  the  Transfer  Agent  such  holder's   Preferred   Stock
            Certificates  which such  holder has elected to have  redeemed.  The
            Company shall deliver the applicable Redemption Price to such holder
            within five Business Days after the Company's receipt of a Notice of
            Redemption at Option of Buyer;  provided  that a holder's  Preferred
            Stock  Certificates  shall have been so  delivered  to the  Transfer
            Agent.  If the  Company  is unable to  redeem  all of the  Preferred
            Shares submitted for redemption,  the Company shall (i) redeem a pro
            rata amount from each holder of Preferred Shares based on the number
            of Preferred Shares submitted for redemption by such holder relative
            to the total number of Preferred  Shares submitted for redemption by
            all holders of  Preferred  Shares and (ii) in addition to any remedy
            such holder of Preferred  Shares may have under this  Certificate of
            Amendment and the Securities Purchase Agreement,  pay to each holder
            interest at the rate of 2.0% per month (prorated for partial months)
            in respect of each unredeemed Preferred Share until paid in full.

                        Void Redemption.  In the event that the Company does not
            pay the Redemption Price within the time period set forth in Section
            3(d), at any time  thereafter and until the Company pays such unpaid
            applicable  Redemption  Price in full, a holder of Preferred  Shares
            shall have the option (the "Void Optional Redemption Option") to, in
            lieu of redemption,  require the Company to promptly  return to such
            holder any or all of the  Preferred  Shares that were  submitted for
            redemption  by such  holder  under this  Section 3 and for which the
            applicable Redemption Price (together with any interest thereon) has
            not been

<PAGE>

            paid, by sending written notice thereof to the Company via facsimile
            (the "Void Optional Redemption Notice").  Upon the Company's receipt
            of  such  Void  Optional   Redemption  Notice,  (i)  the  Notice  of
            Redemption at Option of Buyer shall be null and void with respect to
            those  Preferred  Shares  subject  to the Void  Optional  Redemption
            Notice,  and (ii) the Company shall immediately return any Preferred
            Shares subject to the Void Optional Redemption Notice, and (iii) the
            Conversion Price of such returned Preferred Shares shall be adjusted
            to the lesser of (A) the  Conversion  Price as in effect on the date
            on which the Void  Optional  Redemption  Notice is  delivered to the
            Company  and (B) the  lowest  Closing  Bid Price  during  the period
            beginning on the date on which the Notice of Redemption at Option of
            Buyer is  delivered  to the  Company and ending on the date on which
            the Void Optional Redemption Notice is delivered to the Company.

                        Disputes; Miscellaneous. In the event of a dispute as to
            the  determination of the Market Price, the Closing Bid Price or the
            arithmetic  calculation of the Redemption  Price, such dispute shall
            be  resolved  pursuant  to  Section  2(d)(iii)  above  with the term
            "Closing Bid Price" being  substituted  for the term "Market  Price"
            and the  term  "Redemption  Price"  being  substituted  for the term
            "Conversion Rate". A holder's delivery of a Void Optional Redemption
            Notice and  exercise of its rights  following  such notice shall not
            effect the  Company's  obligations  to make any payments  which have
            accrued  prior  to the  date  of  such  notice.  In the  event  of a
            redemption  pursuant  to  this  Section  3 of less  than  all of the
            Preferred  Shares  represented  by  a  particular   Preferred  Stock
            Certificate,  the  Company  shall  promptly  cause to be issued  and
            delivered to the holder of such Preferred  Shares a preferred  stock
            certificate  representing the remaining  Preferred Shares which have
            not been redeemed.

                Section 4. Other Rights of Holders.

                  (a) Reorganization, Reclassification, Consolidation, Merger or
Sale. Any  recapitalization,  reorganization,  reclassification,  consolidation,
merger,  sale of all or  substantially  all of the  Company's  assets to another
Person or other  transaction  which is  effected  in such a way that  holders of
Common  Stock are  entitled  to  receive  (either  directly  or upon  subsequent
liquidation)  stock,  securities  or assets with  respect to or in exchange  for
Common  Stock  is  referred  to  herein  as  "Organic   Change."  Prior  to  the
consummation of any (i) sale of all or substantially all of the Company's assets
to an acquiring  Person or (ii) other Organic Change following which the Company
is not a surviving  entity,  the Company will secure from the Person  purchasing
such assets or the successor  resulting  from such Organic Change (in each case,
the "Acquiring  Entity") a written  agreement (in form and substance  reasonably
satisfactory  to  the  holders  of a  majority  of  the  Preferred  Shares  then
outstanding) to deliver to each holder of Preferred  Shares in exchange for such
shares,  a security of the Acquiring  Entity  evidenced by a written  instrument
substantially similar in form and substance to the Preferred Shares,  including,
without  limitation,  having a stated value and liquidation  preference equal to
the Stated Value and the Liquidation  Preference of

<PAGE>

the Preferred  Shares held by such holder,  and satisfactory to the holders of a
majority of the Preferred Shares then outstanding.  Prior to the consummation of
any other Organic Change, the Company shall make appropriate  provision (in form
and substance  satisfactory to the holders of a majority of the Preferred Shares
then  outstanding)  to insure that each of the holders of the  Preferred  Shares
will  thereafter have the right to acquire and receive in lieu of or in addition
to (as the case may be) the  shares  of  Common  Stock  immediately  theretofore
acquirable and receivable upon the conversion of such holder's  Preferred Shares
such  shares of stock,  securities  or assets  that  would  have been  issued or
payable in such Organic  Change with respect to or in exchange for the number of
shares of Common Stock which would have been  acquirable and receivable upon the
conversion  of such  holder's  Preferred  Shares as of the date of such  Organic
Change  (without  taking into account any  limitations  or  restrictions  on the
convertibility of the Preferred Shares).

                  (b) Optional Redemption Upon Change of Control. In addition to
the rights of the holders of Preferred  Shares under Section 4(a), upon a Change
of Control (as defined  below) of the Company  each holder of  Preferred  Shares
shall have the right, as such holder's option,  to require the Company to redeem
all or a portion  of such  holder's  Preferred  Shares at a price per  Preferred
Share equal to the greater of (A) 125% of the Liquidation Preference and (B) the
Product of (y) the  Conversion  Rate on the date the holder of Preferred  Shares
gives a Notice of  Redemption  Upon  Change of  Control  and (C) the  arithmetic
average  of the  Closing  Bid  Prices of the  Common  Stock  during the five (5)
trading days immediately  preceding such date on which the Principal  Market, or
the  market or  exchange  where the  Common  Stock is then  traded,  is open for
trading ("Change of Control Redemption Price"). No sooner than 15 days nor later
than 10 days prior to the consummation of a Change of Control,  but not prior to
the public  announcement  of such Change of Control,  the Company  shall deliver
written notice thereof via facsimile and overnight  courier (a "Notice of Change
of Control") to each holder of Preferred  Shares.  At any time during the period
beginning  after  receipt of a Notice of Change of Control  (or,  in the event a
Notice of Change of Control is not  delivered at least 10 days prior to a Change
of Control,  at any time on or after the date which is 10 days prior to a Change
of Control) and ending on the date of such Change of Control,  any holder of the
Preferred  Shares  then  outstanding  may require the Company to redeem all or a
portion of the holder's  Preferred Shares then outstanding by delivering written
notice thereof via facsimile and overnight courier (a "Notice of Redemption Upon
Change of Control") to the Company,  which Notice of  Redemption  Upon Change of
Control  shall  indicate (i) the number of Preferred  Shares that such holder is
submitting for redemption,  and (ii) the applicable Change of Control Redemption
Price, as calculated  pursuant to this Section 4(b). Upon the Company's  receipt
of a Notice(s) of Redemption Upon Change of Control from any holder of Preferred
Shares, the Company shall promptly,  but in no event later than one (1) Business
Day following such receipt,  notify each holder of Preferred Shares by facsimile
of the Company's receipt of such Notice(s) of Redemption Upon Change of Control.
The Company  shall deliver the  applicable  Change of Control  Redemption  Price
simultaneous  with the consummation of the Change of Control;  provided that, if
required by Section  2(d)(viii),  a holder's  Preferred

<PAGE>

Stock  Certificates  shall  have  been so  delivered  to the  Company.  Payments
provided  for in this  Section  4(b) shall have  priority  to  payments to other
stockholders  in  connection  with a Change of  Control.  For  purposes  of this
Section 4(b), "Change of Control" means (i) the  consolidation,  merger or other
business  combination of the Company with or into another Person (other than (A)
a  consolidation,  merger or other business  combination in which holders of the
Company's voting power immediately  prior to the transaction  continue after the
transaction to hold,  directly or indirectly,  the voting power of the surviving
entity or entities  necessary to elect a majority of the members of the board of
directors (or their  equivalent if other than a  corporation)  of such entity or
entities,  or (B) pursuant to a migratory merger effected solely for the purpose
of changing the jurisdiction of incorporation of the Company),  (ii) the sale or
transfer  of all or  substantially  all of the  Company's  assets,  or  (iii)  a
purchase,  tender or exchange  offer made to and accepted by the holders of more
than the 50% of the outstanding shares of Common Stock.

                  (c) Forced  Delisting.  If a  redemption  voided  pursuant  to
Section 3(e) was caused by a Triggering Event involving the Company's  inability
to issue  Conversion  Shares because of the Primary  Exchange Cap (as defined in
Section 14), and if so directed by the holders of at least  two-thirds  (2/3) of
the Preferred  Shares then  outstanding,  including  shares of Preferred  Shares
submitted  for  redemption  pursuant  to  Section  3 with  respect  to which the
applicable  Redemption  Price has not been paid, in a Void Mandatory  Redemption
Notice,  the Company shall immediately  delist the Common Stock from exchange or
automated  quotation  system on which the  Common  Stock is traded  and have the
Common Stock, at such holders' option,  traded on the electronic  bulletin board
or the "pink sheets".

                  (d) Purchase Rights. If at any time the Company grants, issues
or sells any  Options,  Convertible  Securities  or rights  to  purchase  stock,
warrants,  securities  or other  property pro rata to the record  holders of any
class of Common  Stock (the  "Purchase  Rights"),  then the holders of Preferred
Shares will be entitled to acquire,  upon the terms  applicable to such Purchase
Rights,  the aggregate  Purchase Rights which such holder could have acquired if
such  holder  had held the  number of shares of  Common  Stock  acquirable  upon
complete  conversion of the Preferred  Shares  (without  taking into account any
limitations  or  restrictions  on the  convertibility  of the Preferred  Shares)
immediately  before the date on which a record is taken for the grant,  issuance
or sale of such Purchase Rights,  or, if no such record is taken, the date as of
which the record  holders of Common  Stock are to be  determined  for the grant,
issue or sale of such Purchase Rights.

                  Section 5.  Limitation  on Beneficial  Ownership.  The Company
shall not effect any  conversion of Preferred  Shares and no holder of Preferred
Shares shall have the right to convert Preferred Shares in excess of that number
of Preferred Shares which,  upon giving effect to such  conversion,  would cause
the aggregate number of shares of Common Stock  beneficially owned by the holder
and its  affiliates  to exceed 4.99% of the total  outstanding  shares of Common
Stock  following such  conversion.  For purposes of the foregoing  proviso,  the
aggregate number of shares of

<PAGE>

Common Stock  beneficially  owned by the holder and its affiliates shall include
the number of shares of Common Stock  issuable upon  conversion of the Preferred
Shares with  respect to which the  determination  of such proviso is being made,
but shall  exclude the number of shares of Common  Stock which would be issuable
upon (i) conversion of the remaining, nonconverted Preferred Shares beneficially
owned by the holder and its  affiliates  and (ii)  exercise or conversion of the
unexercised  or  unconverted  portion  of any other  securities  of the  Company
(including,  without  limitation,  any warrants or convertible  preferred stock)
subject to a limitation on conversion  or exercise  analogous to the  limitation
contained herein beneficially owned by the holder and its affiliates.  Except as
set forth in the preceding sentence,  for purposes of this Section 5, beneficial
ownership shall be calculated in accordance with Section 13(d) of the Securities
Exchange Act of 1934, as amended. For purposes of this Section 5, in determining
the number of outstanding shares of Common Stock a holder may rely on the number
of  outstanding  shares of Common Stock as reflected in (1) the  Company's  most
recent  Form 10-Q or Form  10-K,  as the case may be, (2) a more  recent  public
announcement  by the  Company  or (3) any  other  notice by the  Company  or its
transfer  agent setting forth the number of shares of Common Stock  outstanding.
Upon the written request of any holder,  the Company shall  promptly,  but in no
event later than one (1)  Business  Day  following  the receipt of such  notice,
confirm  in writing to any such  holder the number of shares  Common  Stock then
outstanding. In any case, the number of outstanding shares Common Stock shall be
determined  after giving effect to conversions of Preferred  Shares and exercise
of Warrants (as defined below) by such holder and its affiliates  since the date
as of which such  number of  outstanding  shares of Common  Stock was  reported.
Notwithstanding  the foregoing,  each holder of Preferred  Shares shall have the
sole obligation to determine whether the restrictions  contained in this Section
5 apply to such  holder.  For the purpose of making  determinations  pursuant to
this  Section 5, the Company may assume that no  affiliate of a holder holds any
shares of Common  Stock  unless  notified  in writing  by a holder of  Preferred
Shares.

                  Section 6.  Redemption at the Company's  Election.  On any day
after the  Initial  Issuance  Date and  prior to the date  which is one (1) year
after the Initial  Issuance Date, the Company shall have the right,  in its sole
discretion,  to require that any or all of the outstanding  Preferred  Shares be
redeemed  ("Redemption at Company's  Election") for  consideration  equal to the
Company's  Election  Redemption  Price (as  defined  below);  provided  that the
Conditions  to  Redemption  at the  Company's  Election (as set forth below) are
satisfied.  The Company  shall  exercise  its right to  Redemption  at Company's
Election by providing each holder of Preferred Shares written notice ("Notice of
Redemption at Company's  Election") by facsimile and overnight  courier.  If the
Company elects to redeem some, but not all, of the Preferred Shares, the Company
shall redeem a pro rata amount from each holder of Preferred Shares based on the
number  of  Preferred  Shares  held by such  holder  relative  to the  number of
Preferred Shares outstanding on the date of the Company's delivery of the Notice
of  Redemption  at  Company's  Election  (such amount with respect to the Holder
being  referred to herein as its "Pro Rata  Redemption  Amount").  The Notice of
Redemption  at  Company's  Election  shall  indicate (x) the number of Preferred

<PAGE>

Shares the Company has selected to redeem,  (y) the date selected by the Company
for redemption  ("Company's  Election Redemption Date"), which date shall be not
less than 20 or more than 30 Business Days after each  holder's  receipt of such
notice,  and (z) each holder's Pro Rata  Redemption  Amount.  If the Company has
exercised its right of Redemption  at Company's  Election and the  conditions of
this Section 6,  including the  Conditions to Redemption at Company's  Election,
have been  satisfied,  then each  Buyer's Pro Rata  Redemption  Amount  shall be
redeemed as of the Company's Election  Redemption Date by payment by the Company
to each Buyer of the  Company's  Election  Redemption  Price for each  Preferred
Share  redeemed.  If required by Section  2(d)(viii),  all holders of  Preferred
Shares shall thereupon and within two Business Days after the Company's Election
Redemption  Date  surrender  all  Preferred  Stock  Certificates   selected  for
redemption,  duly endorsed for cancellation,  to the Transfer Agent. "Conditions
to Redemption at the Company's Election" means the following conditions:  (i) on
each day during the period  beginning the date the SEC declares the Registration
Statement  registering  the Registrable  Securities  effective and ending on and
including the Company's  Election  Redemption Date, the  Registration  Statement
shall  be  effective  and  available  for the  sale of no less  than  all of the
Registrable  Securities,  (ii) on each day during the  period  beginning  on the
Initial  Issuance  Date and  ending  on and  including  the  Company's  Election
Conversion Date, the Common Stock is reported on OTCBB, designated for quotation
on The Nasdaq SmallCap Market or the Nasdaq National Market or listed on The New
York Stock  Exchange,  Inc. or The American Stock  Exchange,  Inc. and shall not
have been  suspended  from  trading on such  exchanges or quotation or reporting
systems nor shall  delisting  or  suspension  by such  exchanges or quotation or
reporting  systems have been threatened  either (A) in writing by such exchanges
or quotation or reporting  systems or (B) by falling  below the minimum  listing
maintenance  requirements  of such exchanges or quotation or reporting  systems;
(iii) the Company shall not have previously given more than three (3) Notices of
Redemption  at  Company's  Election;  (iv)  during the period  beginning  on the
Initial  Issuance  Date and  ending  on and  including  the  Company's  Election
Conversion  Date,  the  Company  shall have  delivered  Conversion  Shares  upon
conversion  of the  Preferred  Shares and Warrant  Shares  upon  exercise of the
Warrants  to the Buyers on a timely  basis as set forth in Section  2(d)(ii)  of
this  Certificate  of  Amendment  and  Sections  2(a) and 2(b) of the  Warrants,
respectively; and (v) the Company otherwise has satisfied its obligations and is
not in default under this  Certificate  of Amendment,  the  Securities  Purchase
Agreement,  the Warrants and the Registration  Rights Agreement.  The "Company's
Election  Redemption Price" shall mean (A) prior to the date which is six months
after the Initial  Issuance Date,  115% of the Stated Value and (B) on and after
the date which is six months  after the Initial  Issuance  Date but prior to the
date which is one (1) year after the Initial  Issuance Date,  120% of the Stated
Value.  Notwithstanding  the above,  any holder of Preferred  Shares may convert
such shares  (including  Preferred  Shares selected for redemption)  into Common
Stock pursuant to Section 2(a) on or prior to the date immediately preceding the
Company's  Election  Redemption  Date.  If the  Company  fails to timely pay any
Company's Election  Redemption Price in accordance with this Section 6, then the
Company  shall not be  permitted  to submit  another  Notice  of  Redemption  at
Company's  Election  without  the prior  written  consent of the  holders of

<PAGE>

the Preferred  Shares  representing at least  two-thirds  (2/3) of the Preferred
Shares then outstanding.

                  Section 7.  Company's  Right to Redeem in Lieu of  Conversion.
Subject  to the terms and  conditions  of this  Section 7, at any time after the
Initial  Issuance  Date,  and so long as the  Company has  provided  appropriate
notice as  described  below,  the Company may elect to redeem  Preferred  Shares
submitted for conversion in lieu of converting such Preferred  Shares,  provided
that the  Conversion  Price  for such  Preferred  Shares  (as  reflected  in the
Conversion Notice for such Preferred Shares) on the Conversion Date is less than
a price (the  "Redemption in Lieu of Conversion  Trigger  Price") equal to $3.00
(appropriately  adjusted for any stock split,  stock  dividend,  combination  or
other similar  transaction) (a "Company  Redemption in Lieu of Conversion").  If
the  Company  elects  to  redeem  some,  but not all,  of the  Preferred  Shares
submitted for conversion,  the Company shall redeem a number of Preferred Shares
from each holder of Preferred  Shares submitted for conversion on the applicable
date equal to such  holder's  pro-rata  amount (based on the number of Preferred
Shares  held  by  such  holder  relative  to  the  number  of  Preferred  Shares
outstanding) of all Preferred  Shares submitted for conversion which the Company
elects to redeem.

            (a)  Redemption  Price of Company  Redemption in Lieu of Conversion.
The "Redemption  Price of Company  Redemption in Lieu of Conversion" shall be an
amount per Preferred  Share equal to the product of (i) the  Conversion  Rate on
the  applicable  Conversion  Date and (ii) the  Closing  Bid Price of the Common
Stock on the Conversion Date.

            (b)  Mechanics  of Company  Redemption  in Lieu of  Conversion.  The
Company  shall  exercise  its right to redeem by  delivering  written  notice by
facsimile  and  overnight  courier  ("Notice  of Company  Redemption  in Lieu of
Conversion")  to (i) each holder of the  Preferred  Shares and (ii) the Transfer
Agent on any day immediately  following a date on which the Conversion  Price is
less than $3.00.  Such Notice of Company  Redemption in Lieu of Conversion shall
indicate (A) the maximum, if any, aggregate number of Preferred Shares which the
Company  will  redeem  in  connection  with the  Company  Redemption  in Lieu of
Conversion,  (B)  confirm the time  period  during  which the Company may effect
Company  Redemption  in Lieu of  Conversion,  which  period  shall  begin on and
include the date of  delivery to all of the holders of the Notice of  Redemption
in Lieu of Conversion and shall end on and include the date which is 30 calendar
days after the date of receipt by all of the holders of the Notice of Redemption
in Lieu of Conversion  (the  "Redemption in Lieu of Conversion  Period") and (C)
each  holder's pro rata amount as described in the  following  sentence.  If the
Company  elects to limit the number of  Preferred  Shares  which it will  redeem
during the Redemption in Lieu of Conversion  Period,  the Company shall allocate
for redemption from each holder of Preferred Shares a number of Preferred Shares
equal to such holder's  pro-rata amount (based on the number of Preferred Shares
held by such holder on the date of the Notice of Company  Redemption  in Lieu of
Conversion  relative to the total number of Preferred Shares

<PAGE>

outstanding  on such date).  The Company may  terminate a Redemption  in Lieu of
Conversion  Period at any time with respect to  Preferred  Shares which have not
been submitted for conversion by delivering  written notice of such  termination
to each holder of Preferred  Shares by facsimile and overnight  courier at least
five  (5)  Business  Days  prior  to the  effective  date of  such  termination.
Notwithstanding  anything to the contrary in this  Section 7, the Company  shall
convert  Preferred  Shares  pursuant to Section 2 if such  Preferred  Shares are
submitted for conversion  (i) before the beginning,  or after the effective date
of the termination,  of the Redemption in Lieu of Conversion Period,  (ii) for a
Conversion  Price (as reflected in the Conversion  Notice) greater than or equal
to the Redemption in Lieu of Conversion  Trigger Price or (iii) are in excess of
such holder's pro rata allocation of the maximum number of Preferred  Shares the
Company  indicated  that it would redeem in its Notice of Company  Redemption in
Lieu of Conversion.

            (c)  Payment  of  Redemption   Price.  The  Company  shall  pay  the
applicable  Redemption Price of Company  Redemption in Lieu of Conversion to the
holder of the Preferred  Shares being  redeemed in cash by wire transfer by 5:00
p.m.  New  York  City  time on the  first  Business  Day  after  the  applicable
Conversion Date on which such Preferred Shares are submitted for conversion.  If
the  Company  shall  fail to pay the  applicable  Redemption  Price  of  Company
Redemption  in Lieu of  Conversion to such holder on a timely basis as described
in this Section 7(c), in addition to any remedy such holder of Preferred  Shares
may have  under  this  Certificate  of  Amendment  and the  Securities  Purchase
Agreement,  such unpaid amount shall bear interest at the rate of 1.5% per month
until  paid  in  full.  If the  Company  fails  to pay  such  unpaid  applicable
Redemption Price of Company Redemption in Lieu of Conversion by 5:00 p.m. on the
first  Business Day following  the  applicable  Conversion  Date in full to each
holder,  each holder of Preferred  Shares  submitted for redemption  pursuant to
this  Section  7 and for  which  the  applicable  Redemption  Price  of  Company
Redemption in Lieu of Conversion has not been paid, shall have the option to, in
lieu of redemption, (A) to require the Company to promptly return to each holder
all of the Preferred  Shares that were  submitted for  redemption by such holder
under this Section 7 and for which the  applicable  Redemption  Price of Company
Redemption  in Lieu of  Conversion  has not been  paid or (B) to  convert  those
Preferred  Shares  for  which the  applicable  Redemption  Price of the  Company
Redemption in Lieu of Conversion  has not been paid at a Conversion  Price equal
to the lesser of (I) the Conversion  Price  applicable to such conversion on the
date on which such Preferred Shares were originally presented for conversion and
(II) the  Conversion  Price  which  would have been in effect if such  Preferred
Shares were presented for conversion on the Business Day  immediately  following
the last  day on  which  the  Company  could  have  effected  a  timely  Company
Redemption  in Lieu of  Conversion,  by sending  written  notice  thereof to the
Company via facsimile (the "Void Company  Redemption  Notice") at any time after
5:00 p.m. on the first  Business Day following the applicable  Conversion  Date.
Upon the Company's  receipt of such Void Company  Redemption  Notice(s) prior to
payment of the full applicable  redemption  price to each holder,  the Company's
Redemption  in Lieu of  Conversion  shall be null and void with respect to those
Preferred   Shares  submitted  for  redemption  and  for  which  the  applicable
redemption

<PAGE>

price has not been paid and with respect to any  Preferred  Shares  submitted in
the future for conversion in the same  Redemption in Lieu of Conversion  Period.
In the case of the Void Company  Redemption  Notice requesting the return of the
Preferred Shares (i) the Company shall  immediately  return any Preferred Shares
submitted to the Company by each holder for redemption  under this Section 7 and
for which the  applicable  Redemption  Price of  Company  Redemption  in Lieu of
Conversion  has not  been  paid  and (ii)  the  Fixed  Conversion  Price of such
returned  Preferred Shares shall be adjusted to the lesser of (I) the Conversion
Price  applicable to such conversion on the date on which such Preferred  Shares
were originally  presented for conversion and (II) the lowest  Conversion  Price
which  would have been in effect if such  Preferred  Shares were  presented  for
conversion  on any Business Day during the period  beginning on the Business Day
immediately  following  the last day on which the Company  could have effected a
timely  Company  Redemption in Lieu of Conversion  and ending on the date of the
Company's receipt of the applicable Void Company  Redemption Notice. In the case
of the Void Company Redemption Notice requesting the conversion of the Preferred
Shares,  such  conversion  shall be at the Conversion  Price indicated above and
shall satisfy the  requirements  of Section 2(d) based on the Conversion Date on
which  such  Preferred   Shares  were   originally   submitted  for  conversion.
Notwithstanding  the  foregoing,  if the  Company  fails  to pay the  applicable
Redemption Price of Company  Redemption in Lieu of Conversion to a holder within
the time  period  described  in this  Section  7(c) due to a  dispute  as to the
arithmetic  calculation of the Redemption Price of Company Redemption in Lieu of
Conversion,  such dispute shall be resolved  pursuant to Section 2(d)(iii) above
with the term  "Redemption  Price of Company  Redemption in Lieu of  Conversion"
being substituted for the term "Conversion Rate." If the Company fails to timely
effect a  Company  Redemption  in Lieu of  Conversion  in  accordance  with this
Section 7, the Company shall not be allowed to submit  another Notice of Company
Redemption  in Lieu of  Conversion  without  the prior  written  consent  of the
holders of at least two-thirds (y) of the Preferred Shares then outstanding.

            (d)  Company  Must  Have  Immediately   Available  Funds  or  Credit
Facilities.  The  Company  shall not be  entitled  to send any Notice of Company
Redemption  in Lieu of  Conversion  pursuant to Section 7(b) above and begin the
redemption procedure under this Section 7, unless it has:

                  the full amount of the Redemption Price of Company  Redemption
in Lieu of  Conversion  in  cash,  available  in a demand  or other  immediately
available account in a bank or similar financial institution;

                  credit   facilities,   with  a  bank  or   similar   financial
institutions  that are available for use in redeeming the Preferred  Shares,  in
the full  amount  of the  Redemption  Price  of  Company  Redemption  in Lieu of
Conversion;

                  a written agreement with a standby underwriter ready,  willing
and able to purchase from the Company a sufficient  number of shares of stock to
provide proceeds necessary to redeem any Preferred Shares that are not converted

<PAGE>

prior to a Company Redemption in Lieu of Conversion; or

                  a combination of the items set forth in the preceding  clauses
(i),  (ii) and (iii),  aggregating  the full amount of the  Redemption  Price of
Company Redemption in Lieu of Conversion.

            Section 8. Reservation of Shares; Authorized Shares.

                  Reservation.  The  Company  shall,  so  long  as  any  of  the
      Preferred Shares are outstanding, take all action necessary to reserve and
      keep available out of its authorized and unissued Common Stock, solely for
      the purpose of effecting  the  conversion of the  Preferred  Shares,  such
      number of shares of Common Stock as shall from time to time be  sufficient
      to effect the conversion of all of the Preferred Shares then  outstanding;
      provided that the number of shares of Common Stock so reserved shall at no
      time be less than 200% of the  number of shares of Common  Stock for which
      the Preferred  Shares are at any time  convertible  (without regard to any
      limitations on conversions)  (the "Required  Reserve Amount).  The initial
      number of shares of Common Stock reserved for conversions of the Preferred
      Shares  and each  increase  in the number of shares so  reserved  shall be
      allocated pro rata among the holders of the Preferred  Shares based on the
      number of Preferred  Shares held by each holder at the time of issuance of
      the Preferred Shares or increase in the number of reserved shares,  as the
      case may be. In the event a holder shall sell or otherwise transfer any of
      such holder's  Preferred Shares,  each transferee shall be allocated a pro
      rata portion of the number of reserved shares of Common Stock reserved for
      such transferor.  Any shares of Common Stock reserved and allocated to any
      Person which ceases to hold any Preferred Shares shall be allocated to the
      remaining  holders of  Preferred  Shares,  pro rata based on the number of
      Preferred Shares then held by such holders.

                  Insufficient  Authorized  Shares.  If at any time while any of
      the  Preferred  Shares  remain  outstanding  the  Company  does not have a
      sufficient  number of authorized and unreserved  shares of Common Stock to
      satisfy its  obligation  to reserve for issuance  upon  conversion  of the
      Preferred  Shares at least a number of shares of Common Stock equal to the
      Required Reserve Amount (an "Authorized Share Failure"),  then the Company
      shall  immediately  take all action  necessary to increase  the  Company's
      authorized  shares of Common  Stock to an amount  sufficient  to allow the
      Company to reserve the Required  Reserve  Amount for the Preferred  Shares
      then  outstanding.  Without  limiting  the  generality  of  the  foregoing
      sentence,  as soon as  practicable  after the date of the occurrence of an
      Authorized  Share  Failure,  but in no event  later than 60 days after the
      occurrence  of such  Authorized  Share  Failure,  the Company shall hold a
      meeting of its  stockholders  for the  authorization of an increase in the
      number of  authorized  shares of Common  Stock.  In  connection  with such
      meeting, the Company shall provide each stockholder with a proxy statement
      and shall use its  reasonable  best  efforts to

<PAGE>

      solicit its  stockholders'  approval of such increase in authorized shares
      of Common  Stock and to cause its board of  directors  to recommend to the
      stockholders that they approve such proposal.

            Section 9. Voting Rights.  Holders of Preferred Shares shall have no
voting rights,  except as required by law,  including but not limited to the New
York  Business  Corporation  Law of the  State  of New  York,  and as  expressly
provided in this Certificate of Amendment.

            Section 10. Liquidation,  Dissolution,  Winding-Up.  In the event of
any  voluntary  or  involuntary  liquidation,  dissolution  or winding up of the
Company,  the holders of the  Preferred  Shares  shall be entitled to receive in
cash out of the assets of the Company,  whether  from  capital or from  earnings
available for distribution to its stockholders (the "Liquidation Funds"), before
any  amount  shall be paid to the  holders  of any of the  capital  stock of the
Company of any class  junior in rank to the  Preferred  Shares in respect of the
preferences as to the distributions and payments on the liquidation, dissolution
and  winding up of the  Company,  an amount  per  Preferred  Share  equal to the
Conversion  Amount (otherwise the "Liquidation  Preference");  provided that, if
the Liquidation Funds are insufficient to pay the full amount due to the holders
of  Preferred  Shares  and  holders  of  shares  of other  classes  or series of
preferred stock of the Company that are of equal rank with the Preferred  Shares
as to payments of Liquidation Funds (the "Pari Passu Shares"),  then each holder
of  Preferred  Shares and Pari Passu Shares  shall  receive a percentage  of the
Liquidation  Funds equal to the full amount of Liquidation Funds payable to such
holder  as  a  liquidation  preference,  in  accordance  with  their  respective
Certificate of Amendment,  Preferences  and Rights,  as a percentage of the full
amount of Liquidation  Funds payable to all holders of Preferred Shares and Pari
Passu  Shares.  The purchase or redemption by the Company of stock of any class,
in any manner permitted by law, shall not, for the purposes hereof,  be regarded
as a  liquidation,  dissolution  or  winding  up of  the  Company.  Neither  the
consolidation  or merger of the Company with or into any other  Person,  nor the
sale or transfer by the  Company of less than  substantially  all of its assets,
shall,  for the purposes hereof,  be deemed to be a liquidation,  dissolution or
winding up of the Company.  No holder of  Preferred  Shares shall be entitled to
receive any amounts with respect  thereto upon any  liquidation,  dissolution or
winding up of the Company other than the amounts  provided for herein;  provided
that a holder of Preferred  Shares  shall be entitled to all amounts  previously
accrued with respect to amounts owed hereunder.

            Section  11.  Preferred  Rank.  All  shares of Common  Stock and the
Company's  Series C Preferred  Stock.  par value $0.05 per share (the  "Series C
Preferred  Stock") shall be of junior rank to all Preferred Shares in respect to
the  preferences  as  to  distributions   and  payments  upon  the  liquidation,
dissolution  and winding up of the  Company.  The rights of the shares of Common
Stock and the Series C Preferred  Stock shall be subject to the  preferences and
relative  rights of the  Preferred  Shares.  Without the prior  express  written
consent of the holders of not less than two-thirds (2/3) of the then outstanding
Preferred Shares, the Company shall not hereafter  authorize or issue additional
or other capital  stock that is of senior or equal rank to the Preferred  Shares
in  respect  of the  preferences  as to  distributions  and  payments  upon  the
liquidation,  dissolution  and  winding  up of the  Company.  Without  the prior
express written consent of the holders of not less than two-thirds  (2/3) of the
then outstanding  Preferred Shares, the Company shall not

<PAGE>

hereafter  authorize  or make any  amendment  to the  Company's  Certificate  of
Incorporation or bylaws, or file any resolution of the board of directors of the
Company  with the  Secretary of State of the State of New York or enter into any
agreement  containing any provisions,  which would adversely affect or otherwise
impair the rights or relative  priority of the holders of the  Preferred  Shares
relative to the holders of the Common Stock or the holders of any other class of
capital stock. In the event of the merger or  consolidation  of the Company with
or into another corporation,  the Preferred Shares shall maintain their relative
powers,  designations  and  preferences  provided for herein and no merger shall
result inconsistent therewith.

            Section 12. Participation.  Subject to the rights of the holders, if
any, of the Pari Passu  Shares,  the holders of the Preferred  Shares shall,  as
holders of Preferred Stock, be entitled to such dividends paid and distributions
made to the  holders of Common  Stock to the same  extent as if such  holders of
Preferred  Shares had converted the Preferred  Shares into Common Stock (without
regard to any  limitations on conversion  herein or elsewhere) and had held such
shares of Common Stock on the record date for such dividends and  distributions.
Payments  under  the  preceding  sentence  shall be made  concurrently  with the
dividend or  distribution  to the holders of Common Stock.  Notwithstanding  the
foregoing,  this Section 12 shall not apply if the Company makes a cash dividend
payment to the holders of the Common Stock if such dividend  meets the following
qualifications:  (i) the dividend is paid out of current  earnings accrued after
the  Issuance  Date and  (ii)  the  dividend  is a  non-extraordinary  quarterly
dividend.

            Section 13. Restriction on Redemption and Cash Dividends.  Until all
of the Preferred Shares have been converted or redeemed as provided herein,  the
Company shall not,  directly or indirectly,  redeem,  or declare or pay any cash
dividend or distribution  on, its Common Stock without the prior express written
consent of the holders of not less than two-thirds (2/3) of the then outstanding
Preferred Shares.

            Section 14. Limitation on Number of Conversion  Shares.  The Company
shall not be obligated to issue any shares of Common  Stock upon  conversion  of
the Preferred Shares if the issuance of such shares of Common Stock would exceed
that  number of  shares  of  Common  Stock  which  the  Company  may issue  upon
Conversion of the Preferred  Shares (the "Exchange  Cap") without  breaching the
Company's obligations under the rules or regulations of the Principal Market, or
the market or exchange  where the Common Stock is then traded,  except that such
limitation  shall  not apply in the  event  that the  Company  (a)  obtains  the
approval  of its  stockholders  as  required  by  the  applicable  rules  of the
Principal  Market,  or the market or  exchange  where the  Common  Stock is then
traded,  (or any successor rule or regulation)  for issuances of Common Stock in
excess of such amount or (b) obtains a written  opinion

<PAGE>

from outside  counsel to the Company that such approval is not  required,  which
opinion  shall be  reasonably  satisfactory  to the holders of a majority of the
Preferred  Shares then  outstanding.  Until such approval or written  opinion is
obtained,  no purchaser of Preferred Shares pursuant to the Securities  Purchase
Agreement  (the  "Purchasers")  shall be issued,  upon  conversion  of Preferred
Shares,  shares of Common Stock in an amount greater than the product of (i) the
Exchange Cap amount multiplied by (ii) a fraction, the numerator of which is the
number of Preferred  Shares issued to such Purchaser  pursuant to the Securities
Purchase  Agreement and the denominator of which is the aggregate  amount of all
the  Preferred  Shares  issued  to the  Purchasers  pursuant  to the  Securities
Purchase  Agreement  (the  "Cap  Allocation  Amount").  In the  event  that  any
Purchaser  shall sell or otherwise  transfer any of such  Purchaser's  Preferred
Shares, the transferee shall be allocated a pro rata portion of such Purchaser's
Cap Allocation  Amount.  In the event that any holder of Preferred  Shares shall
convert all of such holder's  Preferred Shares into a number of shares of Common
Stock which, in the aggregate, is less than such holder's Cap Allocation Amount,
then the difference  between such holder's Cap Allocation  Amount and the number
of shares of Common Stock  actually  issued to such holder shall be allocated to
the  respective  Cap  Allocation  Amounts of the remaining  holders of Preferred
Shares on a pro rata basis in proportion to the number of Preferred  Shares then
held by each such holder.

            Section  15.  Vote to Change  the  Terms of  Preferred  Shares.  The
affirmative  vote at a meeting  duly  called  for such  purpose  or the  written
consent without a meeting,  of the holders of not less than two-thirds  (2/3) of
the then outstanding  Preferred Shares,  shall be required for (A) any change to
this  Certificate  of Amendment or the Company's  Certificate  of  Incorporation
which would  amend,  alter,  change or repeal any of the  powers,  designations,
preferences and rights of the Preferred Shares and (B) the issuance of Preferred
Shares other than pursuant to the Securities Purchase Agreement.

            Section 16. Lost or Stolen Certificates. Upon receipt by the Company
of  evidence  reasonably  satisfactory  to  the  Company  of  the  loss,  theft,
destruction or mutilation of any Preferred Stock  Certificates  representing the
Preferred  Shares,  and,  in the case of  loss,  theft  or  destruction,  of any
indemnification  undertaking by the holder to the Company in customary form and,
in the case of  mutilation,  upon  surrender and  cancellation  of the Preferred
Stock Certificate(s),  the Company shall execute and deliver new preferred stock
certificate(s) of like tenor and date; provided,  however, the Company shall not
be  obligated  to  re-issue   preferred   stock   certificates   if  the  holder
contemporaneously  requests  the Company to convert such  Preferred  Shares into
Common Stock.

            Section 17. Remedies, Characterizations, Other Obligations, Breaches
and Injunctive  Relief.  The remedies  provided in this Certificate of Amendment
shall be cumulative and in addition to all other remedies  available  under this
Certificate  of Amendment,  at law or in equity  (including a decree of specific
performance and/or other injunctive relief), no remedy contained herein shall be
deemed a waiver of compliance with the provisions giving rise to such remedy and
nothing  herein shall limit

<PAGE>

a holder's  right to pursue  actual  damages  for any  failure by the Company to
comply with the terms of this Certificate of Amendment. The Company covenants to
each  holder  of  Preferred  Shares  that  there  shall  be no  characterization
concerning this instrument other than as expressly provided herein.  Amounts set
forth or provided for herein with respect to payments,  conversion  and the like
(and the computation  thereof) shall be the amounts to be received by the holder
thereof and shall not, except as expressly  provided  herein,  be subject to any
other  obligation  of the  Company  (or the  performance  thereof).  The Company
acknowledges  that  a  breach  by it of its  obligations  hereunder  will  cause
irreparable  harm to the holders of the Preferred  Shares and that the remedy at
law for any such breach may be inadequate. The Company therefore agrees that, in
the event of any such breach or threatened  breach, the holders of the Preferred
Shares shall be entitled,  in addition to all other  available  remedies,  to an
injunction  restraining  any breach,  without the necessity of showing  economic
loss and without any bond or other security being required.

            Section  18.  Specific  Shall Not Limit  General;  Construction.  No
specific  provision  contained in this  Certificate of Amendment  shall limit or
modify  any  more  general  provision  contained  herein.  This  Certificate  of
Amendment  shall be deemed to be jointly  drafted by the  Company and all Buyers
and shall not be construed against any person as the drafter hereof.

            Section 19. Failure or Indulgence Not Waiver. No failure or delay on
the part of a holder of Preferred Shares in the exercise of any power,  right or
privilege  hereunder shall operate as a waiver thereof,  nor shall any single or
partial exercise of any such power, right or privilege preclude other or further
exercise thereof or of any other right, power or privilege.

            Section 20.  Notice.  Whenever  notice is required to be given under
these Articles of Amendment, unless otherwise provided herein, such notice shall
be given in accordance with Section 9(f) of the Securities Purchase Agreement.

            Section 21.  Conversion  Notice.  Conversion  Notices shall take the
following form:

                               CYBER DIGITAL, INC.

                        WARRANT TO PURCHASE COMMON STOCK

Warrant No.: 1                                       Number of Shares: 190,678

Date of Issuance: October 5, 1999


Cyber Digital,  Inc., a New York corporation  (the "Company"),  hereby certifies
that,  for Ten  United  States  Dollars  ($10.00)  and other  good and  valuable
consideration,  the receipt and  sufficiency  of which are hereby  acknowledged,
HFTP Investment,  L.L.C., the registered holder hereof or its permitted assigns,
is entitled,  subject to the terms set forth below, to purchase from the Company
upon  surrender  of this  Warrant,  at any time or  times  on or after  the date
hereof, but not after 11:59 P.M. Eastern Time on the Expiration Date (as defined
herein) one hundred ninety  thousand six hundred  seventy eight  (190,678) fully
paid  nonassessable  shares of Common  Stock (as defined  herein) of the Company
(the "Warrant  Shares") at the purchase price per share provided in Section 1(b)
below;  provided,  however,  that in no event  shall the holder be  entitled  to
exercise this Warrant for a number of Warrant Shares in excess of that number of
Warrant  Shares  which,  upon giving  effect to such  exercise,  would cause the
aggregate number of shares of Common Stock  beneficially owned by the holder and
its  affiliates  to exceed 4.99% of the  outstanding  shares of the Common Stock
following such exercise.  For purposes of the foregoing  proviso,  the aggregate
number of  shares  of Common  Stock  beneficially  owned by the  holder  and its
affiliates  shall  include the number of shares of Common  Stock  issuable  upon
exercise of this

<PAGE>

Warrant with respect to which the  determination  of such proviso is being made,
but shall  exclude  shares of Common  Stock  which  would be  issuable  upon (i)
exercise of the remaining, unexercised Warrants beneficially owned by the holder
and its  affiliates  and (ii)  exercise  or  conversion  of the  unexercised  or
unconverted portion of any other securities of the Company beneficially owned by
the holder and its affiliates  (including,  without limitation,  any convertible
notes or preferred  stock)  subject to a limitation  on  conversion  or exercise
analogous  to the  limitation  contained  herein.  Except  as set  forth  in the
preceding sentence,  for purposes of this paragraph,  beneficial ownership shall
be calculated in accordance with Section 13(d) of the Securities Exchange Act of
1934, as amended.  For purposes of this Warrant,  in  determining  the number of
outstanding  shares  of  Common  Stock  a  holder  may  rely  on the  number  of
outstanding shares of Common Stock as reflected in (1) the Company's most recent
Form 10-Q or 10QSB or Form 10-K or 10KSB,  as the case may be, (2) a more recent
public announcement by the Company or (3) any other notice by the Company or its
transfer  agent setting forth the number of shares of Common Stock  outstanding.
Upon the written request of any holder,  the Company shall  promptly,  but in no
event later than Two (2)  Business  Day  following  the receipt of such  notice,
confirm in writing to any such holder the number of shares of Common  Stock then
outstanding. In any case, the number of outstanding shares of Common Stock shall
be  determined  after  giving  effect to  conversions  of  Preferred  Shares and
exercise of Warrants (as defined below) by such holder and its affiliates  since
the date as of which  such  number of  outstanding  shares  of Common  Stock was
reported.

      Section 2. Exercise of Warrant.

            (a) Subject to the terms and conditions hereof,  this Warrant may be
exercised by the holder hereof then  registered on the books of the Company,  in
whole or in part,  at any time on any  Business  Day on or after the  opening of
business  on the  date  hereof  and  prior  to 11:59  P.M.  Eastern  Time on the
Expiration  Date  by (i)  delivery  of a  written

<PAGE>

notice, in the form of the subscription notice attached as Exhibit A hereto (the
"Exercise  Notice"),  of such holder's election to exercise this Warrant,  which
notice  shall  specify the number of Warrant  Shares to be  purchased,  (ii) (A)
payment to the Company of an amount  equal to the  applicable  Warrant  Exercise
Price  multiplied  by the number of Warrant  Shares as to which this  Warrant is
being  exercised  (plus any applicable  issue or transfer taxes) (the "Aggregate
Exercise Price") in cash or wire transfer of immediately  available funds or (B)
by  notifying  the Company that this  Warrant is being  exercised  pursuant to a
Cashless  Exercise  (as defined in Section  2(e)) and (iii) the  surrender  to a
common  carrier for  overnight  delivery  to the Company as soon as  practicable
following  such date,  this  Warrant  (or an  indemnification  undertaking  with
respect  to  this  Warrant  in the  case of its  loss,  theft  or  destruction);
provided,  that if such  Warrant  Shares are to be issued in any name other than
that of the registered  holder of this Warrant,  such issuance shall be deemed a
transfer and the  provisions of Section 7 shall be  applicable.  In the event of
any exercise of the rights  represented by this Warrant in compliance  with this
Section 2(a), the Company shall on the second Business Day following the date of
receipt of the Exercise  Notice,  the Aggregate  Exercise  Price (or notice of a
Cashless  Exercise)  and this Warrant (or an  indemnification  undertaking  with
respect to this  Warrant  in the case of its loss,  theft or  destruction)  (the
"Exercise Delivery Documents"), credit such aggregate number of shares of Common
Stock to which the holder  shall be entitled to the  holder's or its  designee's
balance account with The Depository  Trust Company;  provided,  however,  if the
holder who submitted the Exercise Notice requested  physical  delivery of any or
all of the  Warrant  Shares,  then the  Company  shall,  on or before the second
Business Day  following  receipt of the Exercise  Delivery  Documents  issue and
surrender to a common carrier for overnight delivery to the address specified in
the Exercise  Notice, a certificate,  registered in the name of the holder,  for
the  number  of shares of Common  Stock to which the  holder  shall be  entitled
pursuant to such  request.  Upon  delivery of the Exercise  Notice and Aggregate
Exercise  Price  referred  to in clause  (ii)(A)  above or  notification  to the
Company of a Cashless  Exercise  referred to in Section 2(e), the holder of this
Warrant shall be deemed for all corporate  purposes to have become the holder of
record of the  Warrant  Shares  with  respect  to which  this  Warrant  has been
exercised,  irrespective  of the date of delivery of this Warrant as required by
clause (iii) above or the  certificates  evidencing such Warrant Shares.  In the
case of a dispute as to the  determination  of the Warrant Exercise Price or the
Market Price of a security or the arithmetic  calculation of the Warrant Shares,
the Company  shall  promptly  issue to the holder the number of shares of Common
Stock that is not  disputed  and shall  submit the  disputed  determinations  or
arithmetic  calculations to the holder via facsimile  within one Business Day of
receipt of the holder's  subscription  notice. If the holder and the Company are
unable to agree upon the  determination  of the  Warrant  Exercise  Price or the
Market Price or arithmetic calculation of the Warrant Shares within one Business
Day of such disputed  determination or arithmetic calculation being submitted to
the holder,  then the Company  shall  immediately  submit via  facsimile (i) the
disputed  determination  of the Warrant Exercise Price or the Market Price to an
independent,  reputable  investment banking firm or (ii) the disputed arithmetic
calculation of the Warrant Shares to its independent,  outside  accountant.  The
Company shall cause the investment  banking firm or the accountant,  as the

<PAGE>

case may be, to  perform  the  determinations  or  calculations  and  notify the
Company and the holder of the results no later than  forty-eight (48) hours from
the  time  it  receives  the  disputed  determinations  or  calculations.   Such
investment banking firm's or accountant's  determination or calculation,  as the
case may be, shall be deemed conclusive absent manifest error.

            (b) Unless the rights represented by this Warrant shall have expired
or shall have been fully  exercised,  the Company shall,  as soon as practicable
and in no event later than five (5) Business  Days after any exercise and at its
own  expense,  issue a new Warrant  identical  in all  respects to this  Warrant
exercised  except it shall  represent  rights to purchase  the number of Warrant
Shares  purchasable  immediately  prior  to such  exercise  under  this  Warrant
exercised,  less the number of Warrant Shares with respect to which such Warrant
is exercised.

            (c) No  fractional  shares of Common Stock are to be issued upon the
exercise of this Warrant, but rather the number of shares of Common Stock issued
upon  exercise of this Warrant  shall be rounded up or down to the nearest whole
number.

            (d) If the  Company  shall  fail for any  reason or for no reason to
issue to the holder  within four (4)  Business  Days of receipt of the  Exercise
Delivery  Documents,  a certificate  for the number of shares of Common Stock to
which the holder is entitled or to credit the holder's  balance account with The
Depository  Trust Company for such number of shares of Common Stock to which the
holder is entitled  upon the holder's  exercise of this Warrant or a new Warrant
for the  number  of  shares of Common  Stock to which  such  holder is  entitled
pursuant to Section 2(b)  hereof,  the Company  shall,  in addition to any other
remedies  under this Warrant or the Securities  Purchase  Agreement or otherwise
available to such holder,  including any indemnification  under Section 8 of the
Securities Purchase Agreement,  pay as additional damages in cash to such holder
on each day the issuance of such Common Stock certificate or new Warrant, as the
case may be, is not timely effected an amount equal to 0.5%of the product of (A)
the sum of the  number of shares of Common  Stock not  issued to the holder on a
timely  basis and to which the holder is entitled  and/or,  the number of shares
represented by the portion of this Warrant which is not being converted,  as the
case may be, and (B) the average of the  Closing  Bid Price of the Common  Stock
for the three consecutive  trading days immediately  preceding the last possible
date which the Company  could have issued such Common  Stock or Warrant,  as the
case may be, to the holder without violating this Section 2.

            (e) If,  despite  the  Company's  obligations  under the  Securities
Purchase Agreement and the Registration Rights Agreement,  the Warrant Shares to
be issued are not registered and available for resale pursuant to a registration
statement in accordance with the Registration Rights Agreement, including during
a  Grace  Period  (as  defined  in  the  Registration  Rights  Agreement),  then
notwithstanding  anything  contained herein to the contrary,  the holder of this
Warrant may, at its election  exercised in its sole  discretion,  exercise  this
Warrant in whole or in part and,  in lieu of making the cash  payment  otherwise
contemplated  to be made

<PAGE>

to the Company upon such  exercise in payment of the Aggregate  Exercise  Price,
elect instead to receive upon such exercise the "Net Number" of shares of Common
Stock determined according to the following formula (a "Cashless Exercise"):

         Net Number = (A x B) - (A x C)
                      -----------------
                             B

            For purposes of the foregoing formula:

                  A= the total number  shares with respect to which this Warrant
                  is then being exercised.

                  B= the  Closing  Bid  Price  of the  Common  Stock on the date
                  immediately preceding the date of the subscription notice.

                  C=  the  Warrant   Exercise  Price  then  in  effect  for  the
                  applicable Warrant Shares at the time of such exercise.

            (f)  Adjustment to Warrant  Exercise Price -- Market Price of Common
Stock.  In  addition  to any other  adjustment  to the  Warrant  Exercise  Price
provided for in this Warrant,  in the event that 120% of the Market Price of the
Common Stock on the date which is one (1) year after the  issuance  date of this
Warrant  (the "Reset  Date") is less than the Warrant  Exercise  Price in effect
immediately  prior to such Reset  Date,  then from and after such Reset Date the
Warrant  Exercise Price shall be equal to 120% of the Market Price of the Common
Stock on the Reset Date, subject to adjustment as provided herein.

      Section 3. Covenants as to Common Stock.  The Company hereby covenants and
agrees as follows:

            (a) This Warrant is, and any Warrants issued in substitution  for or
replacement  of this Warrant will upon issuance be, duly  authorized and validly
issued.

            (b) All Warrant  Shares which may be issued upon the exercise of the
rights represented by this Warrant will, upon issuance, be validly issued, fully
paid and nonassessable  and free from all taxes,  liens and charges with respect
to the issue thereof.

            (c) During the period  within which the rights  represented  by this
Warrant may be  exercised,  the Company  will at all times have  authorized  and
reserved at least 100% of the number of shares of Common Stock needed to provide
for the  exercise of the rights  then  represented  by this  Warrant and the par
value of said shares  will at all times be less than or equal to the  applicable
Warrant Exercise Price.

            (d) The Company shall  promptly  secure the listing of the shares of
Common  Stock  issuable  upon  exercise  of  this  Warrant  upon  each  national
securities  exchange or

<PAGE>

automated  quotation  system, if any, upon which shares of Common Stock are then
listed  (subject to official  notice of issuance  upon exercise of this Warrant)
and shall  maintain,  so long as any other  shares of Common  Stock  shall be so
listed,  such listing of all shares of Common  Stock from time to time  issuable
upon  the  exercise  of this  Warrant;  and the  Company  shall  so list on each
national  securities exchange or automated quotation system, as the case may be,
and shall  maintain  such listing of, any other  shares of capital  stock of the
Company  issuable upon the exercise of this Warrant if and so long as any shares
of the same  class  shall be  listed on such  national  securities  exchange  or
automated quotation system.

            (e)  The  Company   will  not,  by  amendment  of  its  Articles  of
Incorporation or through any reorganization,  transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action,
avoid or seek to avoid the  observance or  performance of any of the terms to be
observed  or  performed  by it  hereunder,  but will at all times in good  faith
assist in the  carrying  out of all the  provisions  of this  Warrant and in the
taking of all such action as may  reasonably  be requested by the holder of this
Warrant in order to protect the exercise privilege of the holder of this Warrant
against dilution or other  impairment,  consistent with the tenor and purpose of
this Warrant.  No impairment of the designations,  preferences and rights of the
Preferred Shares contained in the Company's  Articles of Amendment or any waiver
thereof which has an adverse  effect on the rights  granted  hereunder  shall be
given effect until the Company has taken appropriate action (satisfactory to the
holders of Preferred  Share  Warrants  representing  a majority of the shares of
Common Stock  issuable upon the exercise of such  Preferred  Share Warrants then
outstanding) to avoid such adverse effect with respect to this Warrant.  Without
limiting the generality of the foregoing,  the Company (i) will not increase the
par value of any shares of Common  Stock  receivable  upon the  exercise of this
Warrant above the Warrant Exercise Price then in effect,  and (ii) will take all
such actions as may be necessary  or  appropriate  in order that the Company may
validly and legally  issue fully paid and  nonassessable  shares of Common Stock
upon the exercise of this Warrant.

            (f) This Warrant will be binding upon any entity  succeeding  to the
Company by merger,  consolidation or acquisition of all or substantially  all of
the Company's assets.

      Section 4.  Taxes.  The  Company  shall pay any and all taxes which may be
payable  with  respect to the  issuance  and  delivery  of Warrant  Shares  upon
exercise of this  Warrant;  provided,  however,  that the  Company  shall not be
required to pay any tax that may be payable in respect of any transfer  involved
in the issue or delivery of Common  Stock or other  securities  or property in a
name other than that of the  registered  holders of this Warrant to be converted
and such holder shall pay such amount, if any, to cover any applicable  transfer
or similar tax.

      Section 5. Warrant  Holder Not Deemed a  Stockholder.  Except as otherwise
specifically  provided  herein,  no holder,  as such,  of this Warrant  shall be
entitled to vote or receive  dividends  or be deemed the holder of shares of the
Company  for any  purpose,  nor shall  anything  contained  in this  Warrant  be
construed  to confer  upon the holder  hereof,  as

<PAGE>

such,  any of the rights of a  stockholder  of the Company or any right to vote,
give or withhold  consent to any corporate  action (whether any  reorganization,
issue of stock, reclassification of stock, consolidation,  merger, conveyance or
otherwise),  receive  notice of  meetings,  receive  dividends  or  subscription
rights, or otherwise, prior to the issuance to the holder of this Warrant of the
Warrant Shares which he or she is then entitled to receive upon the due exercise
of this  Warrant.  In  addition,  nothing  contained  in this  Warrant  shall be
construed as imposing any  liabilities on such holder to purchase any securities
(upon exercise of this Warrant or otherwise) or as a stockholder of the Company,
whether  such  liabilities  are  asserted by the Company or by  creditors of the
Company.  Notwithstanding this Section 5, the Company will provide the holder of
this Warrant with copies of the same notices and other  information given to the
stockholders of the Company generally, contemporaneously with the giving thereof
to the stockholders.

      Section 6.  Representations of Holder. The holder of this Warrant,  by the
acceptance hereof,  represents that it is acquiring this Warrant and the Warrant
Shares for its own account for investment  only and not with a view towards,  or
for resale in connection  with, the public sale or  distribution of this Warrant
or the Warrant Shares, except pursuant to sales registered or exempted under the
Securities Act; provided,  however,  that by making the representations  herein,
the holder does not agree to hold this Warrant or any of the Warrant  Shares for
any minimum or other  specific  term and  reserves  the right to dispose of this
Warrant and the Warrant  Shares at any time in accordance  with or pursuant to a
registration  statement or an exemption  under the Securities Act. The holder of
this Warrant further  represents,  by acceptance hereof,  that, as of this date,
such  holder  is an  "accredited  investor"  as  such  term is  defined  in Rule
501(a)(1) of Regulation D promulgated by the Securities and Exchange  Commission
under the  Securities  Act (an  "Accredited  Investor").  Upon  exercise of this
Warrant,  other than  pursuant  to a Cashless  Exercise  the  holder  shall,  if
requested  by the Company,  confirm in writing,  in a form  satisfactory  to the
Company,  that the Warrant Shares so purchased are being acquired solely for the
holder's own account and not as a nominee for any other party,  for  investment,
and not with a view  toward  distribution  or resale and that such  holder is an
Accredited  Investor.  If such holder cannot make such  representations  because
they would be  factually  incorrect,  it shall be a condition  to such  holder's
exercise of this Warrant that the Company receive such other  representations as
the  Company  considers  reasonably  necessary  to assure the  Company  that the
issuance of its  securities  upon exercise of this Warrant shall not violate any
United States or state securities laws.

      Section 7. Ownership and Transfer.

            (a) The Company shall  maintain at its principal  executive  offices
(or such other office or agency of the Company as it may  designate by notice to
the holder  hereof),  a register for this  Warrant,  in which the Company  shall
record the name and  address of the person in whose name this  Warrant  has been
issued,  as well as the name and  address of each  transferee.  The  Company may
treat the person in whose name any Warrant is  registered on the register as the
owner and holder  thereof for all  purposes,  notwithstanding  any notice to the
contrary,  but in all events  recognizing  any transfers made in accordance with
the terms of this Warrant.

<PAGE>

            (b)  This  Warrant  and  the  rights  granted   hereunder  shall  be
assignable by the holder hereof without the consent of the Company.

            (c) The  Company is  obligated  to register  the Warrant  Shares for
resale under the Securities Act pursuant to the  Registration  Rights  Agreement
and the  initial  holder of this  Warrant  (and  certain  assignees  thereof) is
entitled  to the  registration  rights in respect of the  Warrant  Shares as set
forth in the Registration Rights Agreement.

      Section 8. Adjustment of Warrant Exercise Price and Number of Shares.  The
Warrant  Exercise  Price and the number of shares of Common Stock  issuable upon
exercise of this Warrant shall be adjusted from time to time as follows:

            (a)  Adjustment of Warrant  Exercise Price and Number of Shares upon
Issuance of Common  Stock.  If and  whenever on or after the date of issuance of
this Warrant,  the Company issues or sells, or is deemed to have issued or sold,
any shares of Common  Stock  (other than shares of Common  Stock  deemed to have
been issued by the Company (I) in connection  with an Approved Stock Plan,  (II)
upon the conversion or exercise of convertible  securities which are outstanding
as of  October  1,  1999 and  listed on  Schedule  3(c)(iii)  to the  Securities
Purchase Agreement,  provided that the terms of such convertible securities have
not been  altered,  amended  or  revised  since  October  1, 1999 or (III)  upon
exercise or conversion of the Other  Securities) for a  consideration  per share
less than a price (the " Applicable  Price") equal to the Warrant Exercise Price
in effect  immediately  prior to such issuance or sale, then  immediately  after
such issue or sale the Warrant Exercise Price then in effect shall be reduced to
an amount equal to such  consideration  per share.  Upon each such adjustment of
the  Warrant  Exercise  Price  hereunder,  the number of shares of Common  Stock
acquirable  upon  exercise  of this  Warrant  shall be adjusted to the number of
shares   determined  by  multiplying  the  Warrant   Exercise  Price  in  effect
immediately  prior to such  adjustment  by the number of shares of Common  Stock
acquirable  upon exercise of this Warrant  immediately  prior to such adjustment
and dividing the product  thereof by the Warrant  Exercise Price  resulting from
such adjustment.

            (b) Effect on Warrant Exercise Price of Certain Events. For purposes
of determining the adjusted Warrant Exercise Price under Section 8(a) above, the
following shall be applicable:

                  (i) Issuance of Options.  If the Company in any manner  grants
any Options and the lowest  price per share for which one share of Common  Stock
is issuable upon the exercise of any such Option or upon  conversion or exchange
of any Convertible  Securities issuable upon exercise of any such Option is less
than the Applicable Price, then such share of Common Stock shall be deemed to be
outstanding  and to have been  issued and sold by the Company at the time of the
granting or sale of such Option for such price per share.  For

<PAGE>

purposes of this  Section  8(b)(i),  the  "lowest  price per share for which one
share  of  Common  Stock is  issuable  upon  exercise  of such  Options  or upon
conversion or exchange of such Convertible Securities" shall be equal to the sum
of the lowest  amounts of  consideration  (if any) received or receivable by the
Company  with respect to any one share of Common Stock upon the granting or sale
of the Option,  upon  exercise of the Option and upon  conversion or exchange of
any  Convertible  Security  issuable  upon  exercise of such Option.  No further
adjustment of the Warrant  Exercise Price shall be made upon the actual issuance
of such Common Stock or of such Convertible Securities upon the exercise of such
Options or upon the actual  issuance of such  Common  Stock upon  conversion  or
exchange of such Convertible Securities.

                  (ii) Issuance of Convertible Securities. If the Company in any
manner issues or sells any Convertible Securities and the lowest price per share
for which one share of Common Stock is issuable upon such conversion or exchange
thereof is less than the Applicable Price, then such share of Common Stock shall
be deemed to be  outstanding  and to have been issued and sold by the Company at
the time of the issuance or sale of such  Convertible  Securities for such price
per share.  For the purposes of this  Section  8(b)(ii),  the "lowest  price per
share for which one share of Common Stock is issuable  upon such  conversion  or
exchange" shall be equal to the sum of the lowest amounts of  consideration  (if
any)  received or  receivable by the Company with respect to one share of Common
Stock upon the issuance or sale of the Convertible  Security and upon conversion
or exchange of such Convertible  Security.  No further adjustment of the Warrant
Exercise Price shall be made upon the actual  issuance of such Common Stock upon
conversion or exchange of such Convertible Securities,  and if any such issue or
sale of such  Convertible  Securities  is made upon  exercise of any Options for
which  adjustment  of the  Warrant  Exercise  Price  had  been or are to be made
pursuant to other provisions of this Section 8(b), no further  adjustment of the
Warrant Exercise Price shall be made by reason of such issue or sale.

                  (iii)  Change in Option  Price or Rate of  Conversion.  If the
purchase price provided for in any Options,  the  additional  consideration,  if
any,  payable  upon  the  issue,  conversion  or  exchange  of  any  Convertible
Securities, or the rate at which any Convertible Securities are convertible into
or exchangeable for Common Stock changes at any time, the Warrant Exercise Price
in effect at the time of such change  shall be adjusted to the Warrant  Exercise
Price  which  would  have  been in  effect  at such  time  had such  Options  or
Convertible  Securities  provided for such changed  purchase  price,  additional
consideration  or  changed  conversion  rate,  as the case  may be,  at the time
initially  granted,  issued or sold and the  number  of  shares of Common  Stock
acquirable hereunder shall be correspondingly  readjusted.  For purposes of this
Section 8(b)(iii),  if the terms of any Option or Convertible  Security that was
outstanding as of the date of issuance of this Warrant are changed in the manner
described in the immediately preceding sentence, then such Option or Convertible
Security and the Common Stock  deemed  issuable  upon  exercise,  conversion  or
exchange  thereof  shall be deemed  to have  been  issued as of the date of such
change.  No  adjustment  pursuant  to this  Section  8(b)  shall be made if such
adjustment  would  result in an increase of the Warrant  Exercise  Price then in
effect.

<PAGE>

            (c) Effect on Warrant Exercise Price of Certain Events. For purposes
of determining the adjusted Warrant Exercise Price under Sections 8(a) and 8(b),
the following shall be applicable:

                  (i) Calculation of Consideration  Received. In case any Option
is  issued  in  connection  with the  issue or sale of other  securities  of the
Company,  together  comprising one  integrated  transaction in which no specific
consideration is allocated to such Options by the parties  thereto,  the Options
will be deemed to have been  issued  for a  consideration  of $0.01,  unless the
Board of Directors of the Company shall have made a good faith allocation of the
consideration received for such Option and such other securities,  in which case
such  Option  and such  other  securities  will be deemed  to be issued  for the
consideration  as  allocated  by such  Board.  If any Common  Stock,  Options or
Convertible  Securities are issued or sold or deemed to have been issued or sold
for  cash,  the  consideration  received  therefor  will be deemed to be the net
amount  received  by the  Company  therefor.  If any  Common  Stock,  Options or
Convertible  Securities are issued or sold for a consideration  other than cash,
the amount of such consideration  received by the Company will be the fair value
of such consideration,  except where such consideration  consists of securities,
in which case the amount of  consideration  received by the Company  will be the
Market Price of such  securities  on the date of receipt.  If any Common  Stock,
Options or Convertible  Securities are issued to the owners of the non-surviving
entity in  connection  with any  merger in which the  Company  is the  surviving
entity, the amount of consideration therefor will be deemed to be the fair value
of such portion of the net assets and business of the non-surviving entity as is
attributable  to such Common Stock,  Options or Convertible  Securities,  as the
case may be. The fair value of any  consideration  other than cash or securities
will be determined  by the good faith  determination  of the Company's  Board of
Directors.  If such parties are unable to reach  agreement  within ten (10) days
after the occurrence of an event requiring  valuation (the  "Valuation  Event"),
the fair value of such  consideration  will be  determined  within five Business
Days after the tenth (10th) day following the Valuation Event by an independent,
reputable appraiser jointly selected by the Company and the holders of Preferred
Share Warrants  representing a majority of the shares of Common Stock obtainable
upon  exercise  of  the  Preferred   Share   Warrants  then   outstanding.   The
determination  of such appraiser shall be final and binding upon all parties and
the fees and expenses of such  appraiser  shall be borne  jointly by the Company
and the holders of Preferred Shares.

                  (ii) Integrated Transactions.  In case any Option is issued in
connection with the issue or sale of other  securities of the Company,  together
comprising one  integrated  transaction  in which no specific  consideration  is
allocated to such Options by the parties thereto,  the Options will be deemed to
have been issued for a consideration of $.01.

                  (iii)  Treasury  Shares.  The number of shares of Common Stock
outstanding  at any given time does not include  shares  owned or held by or for
the account of the Company,  and the  disposition of any shares so owned or held
will be considered an issue or sale of Common Stock.

                  (iv) Record Date. If the Company takes a record of the holders
of

<PAGE>

Common  Stock for the  purpose of  entitling  them (1) to receive a dividend  or
other distribution payable in Common Stock, Options or in Convertible Securities
or (2) to  subscribe  for or  purchase  Common  Stock,  Options  or  Convertible
Securities,  then such record date will be deemed to be the date of the issue or
sale of the shares of Common  Stock  deemed to have been issued or sold upon the
declaration  of such  dividend or the making of such other  distribution  or the
date of the granting of such right of subscription or purchase,  as the case may
be.

            (d)  Adjustment  of  Warrant  Exercise  Price  upon  Subdivision  or
Combination  of  Common  Stock.  If the  Company  at any time  after the date of
issuance  of this  Warrant  subdivides  (by any  stock  split,  stock  dividend,
recapitalization  or otherwise) one or more classes of its outstanding shares of
Common  Stock into a greater  number of shares,  any Warrant  Exercise  Price in
effect immediately prior to such subdivision will be proportionately reduced and
the number of shares of Common Stock  obtainable  upon  exercise of this Warrant
will be proportionately  increased. If the Company at any time after the date of
issuance  of this  Warrant  combines  (by  combination,  reverse  stock split or
otherwise) one or more classes of its outstanding  shares of Common Stock into a
smaller number of shares, any Warrant Exercise Price in effect immediately prior
to such combination will be  proportionately  increased and the number of shares
of Common Stock obtainable upon exercise of this Warrant will be proportionately
decreased.  Any adjustment under this Section 8(d) shall become effective at the
close of business on the date the subdivision or combination becomes effective.

            (e) Distribution of Assets. If the Company shall declare or make any
dividend or other  distribution  of its assets (or rights to acquire its assets)
to holders of Common Stock, by way of return of capital or otherwise (including,
without  limitation,  any  distribution  of cash,  stock  or  other  securities,
property or options by way of a dividend, spin off, reclassification,  corporate
rearrangement  or other similar  transaction)  (a  "Distribution"),  at any time
after the issuance of this Warrant, then, in each such case:

                  (i) any Warrant Exercise Price in effect  immediately prior to
the close of business on the record date fixed for the  determination of holders
of Common Stock entitled to receive the Distribution shall be reduced, effective
as of the close of  business  on such  record  date,  to a price  determined  by
multiplying such Warrant Exercise Price by a fraction of which (A) the numerator
shall  be the  Closing  Bid  Price  of the  Common  Stock  on  the  trading  day
immediately  preceding such record date minus the value of the  Distribution (as
determined in good faith by the Company's Board of Directors)  applicable to one
share of Common Stock, and (B) the denominator shall be the Closing Bid Price of
the Common Stock on the trading day immediately preceding such record date; and

                  (ii) either (A) the number of Warrant Shares  obtainable  upon
exercise of this  Warrant  shall be increased to a number of shares equal to the
number of shares of Common Stock  obtainable  immediately  prior to the close of
business  on the record  date fixed for the  determination  of holders of Common
Stock entitled to receive the  Distribution  multiplied by the reciprocal of the
fraction set forth in the immediately  preceding clause (i), or (B) in the event
that the  Distribution  is of common  stock of a company  whose  common stock is
traded on a  national  securities  exchange  or a national  automated  quotation
system,  then the

<PAGE>

holder of this Warrant shall receive an  additional  warrant to purchase  Common
Stock,  the terms of which shall be identical to those of this  Warrant,  except
that such warrant shall be exercisable  into the amount of the assets that would
have been payable to the holder of this Warrant pursuant to the Distribution had
the holder exercised this Warrant immediately prior to such record date and with
an  exercise  price  equal to the  amount  by which the  exercise  price of this
Warrant was decreased with respect to the Distribution  pursuant to the terms of
the immediately preceding clause (i).

            (f) Certain Events.  If any event occurs of the type contemplated by
the  provisions  of  this  Section  8 but  not  expressly  provided  for by such
provisions  (including,  without limitation,  the granting of stock appreciation
rights,  phantom  stock rights or other rights with equity  features),  then the
Company's Board of Directors will make an appropriate  adjustment in the Warrant
Exercise Price and the number of shares of Common Stock obtainable upon exercise
of this  Warrant so as to protect  the  rights of the  holders of the  Preferred
Share  Warrants;  provided  that no such  adjustment  will  increase the Warrant
Exercise  Price or decrease the number of shares of Common Stock  obtainable  as
otherwise determined pursuant to this Section 8.

            (g) Notices.

                  (i)  Immediately  upon any  adjustment  of a Warrant  Exercise
Price,  the  Company  will give  written  notice  thereof  to the holder of this
Warrant, setting forth in reasonable detail, and certifying,  the calculation of
such adjustment.

                  (ii) The  Company  will give  written  notice to the holder of
this  Warrant  at least  ten (10) days  prior to the date on which  the  Company
closes  its  books  or  takes a  record  (A) with  respect  to any  dividend  or
distribution   upon  the  Common  Stock,  (B)  with  respect  to  any  pro  rata
subscription  offer to holders of Common Stock or (C) for determining  rights to
vote with  respect to any Organic  Change (as  defined  below),  dissolution  or
liquidation,  provided that such  information  shall be made known to the public
prior to or in conjunction with such notice being provided to such holder.

                  (iii) The Company will also give written  notice to the holder
of this  Warrant at least ten (10) days  prior to the date on which any  Organic
Change,   dissolution  or  liquidation  will  take  place,  provided  that  such
information  shall be made known to the public prior to or in  conjunction  with
such notice being provided to such holder.

      Section   9.   Purchase    Rights;    Reorganization,    Reclassification,
Consolidation, Merger or Sale.

            (a) In addition to any  adjustments  pursuant to Section 8 above, if
at any  time the  Company  grants,  issues  or sells  any  Options,  Convertible
Securities or rights to purchase

<PAGE>

stock, warrants,  securities or other property pro rata to the record holders of
any class of Common  Stock  (the  "Purchase  Rights"),  then the  holder of this
Warrant will be entitled to acquire,  upon the terms applicable to such Purchase
Rights,  the aggregate  Purchase Rights which such holder could have acquired if
such  holder  had held the  number of shares of  Common  Stock  acquirable  upon
complete exercise of this Warrant  immediately before the date on which a record
is taken for the grant, issuance or sale of such Purchase Rights, or, if no such
record is taken,  the date as of which the record holders of Common Stock are to
be determined for the grant, issue or sale of such Purchase Rights.

            (b)   Any   recapitalization,    reorganization,   reclassification,
consolidation,  merger, sale of all or substantially all of the Company's assets
to another Person or other  transaction in each case which is effected in such a
way that  holders of Common Stock are  entitled to receive  (either  directly or
upon subsequent  liquidation) stock,  securities or assets with respect to or in
exchange  for Common Stock is referred to herein as "Organic  Change."  Prior to
the  consummation of any (i) sale of all or  substantially  all of the Company's
assets to an acquiring  Person or (ii) other Organic Change  following which the
Company is not a  surviving  entity,  the  Company  will  secure from the Person
purchasing  such assets or the successor  resulting from such Organic Change (in
each case,  the  "Acquiring  Entity")  written  agreement (in form and substance
satisfactory to the holders of Preferred Share Warrants  representing a majority
of the shares of Common Stock  obtainable  upon exercise of the Preferred  Share
Warrants then outstanding) to deliver to each holder of Preferred Share Warrants
in exchange for such Warrants, a security of the Acquiring Entity evidenced by a
written instrument  substantially  similar in form and substance to this Warrant
and satisfactory to the holders of the Preferred Share Warrants  (including,  an
adjusted  warrant  exercise  price  equal  to the  value  for the  Common  Stock
reflected by the terms of such  consolidation,  merger or sale, and  exercisable
for a corresponding  number of shares of Common Stock  acquirable and receivable
upon exercise of the Preferred Share Warrants (without regard to any limitations
or exercise),  if the value so reflected is less than any Warrant Exercise Price
in effect immediately prior to such consolidation, merger or sale). Prior to the
consummation  of any other Organic  Change,  the Company shall make  appropriate
provision (in form and substance  satisfactory to the holders of Preferred Share
Warrants  representing a majority of the shares of Common Stock  obtainable upon
exercise of the Preferred  Share Warrants then  outstanding) to insure that each
of the holders of the Preferred Share Warrants will thereafter have the right to
acquire and receive in lieu of or in addition to (as the case may be) the shares
of Common Stock  immediately  theretofore  acquirable  and  receivable  upon the
exercise  of such  holder's  Preferred  Share  Warrants  (without  regard to any
limitations or exercise),  such shares of stock, securities or assets that would
have been  issued or  payable  in such  Organic  Change  with  respect  to or in
exchange  for the  number  of  shares  of Common  Stock  which  would  have been
acquirable and receivable  upon the exercise of such holder's  Warrant as of the
date of such Organic  Change  (without  taking into account any  limitations  or
restrictions on the exerciseability of this Warrant).

      Section 10. Lost, Stolen,  Mutilated or Destroyed Warrant. If this Warrant
is lost,  stolen,  mutilated or destroyed,  the Company shall,  on receipt of an
indemnification  undertaking  (or,  in the  case  of a  mutilated  Warrant,  the
Warrant),  issue a new Warrant of like

<PAGE>

denomination and tenor as this Warrant so lost, stolen, mutilated or destroyed.

      Section 11. Notice. Any notices, consents, waivers or other communications

                          REGISTRATION RIGHTS AGREEMENT

         REGISTRATION RIGHTS AGREEMENT (this "Agreement"), dated as of September
30,  1999,  by and among  Cyber  Digital,  Inc.  a New York  corporation,  with
headquarters located at 400 Oser Avenue, Suite 1650,  Hauppauge,  New York 11788
(the "Company"),  and the undersigned  buyers (each, a "Buyer" and collectively,
the "Buyers").

         WHEREAS:

         A. In connection  with the Securities  Purchase  Agreement by and among
the parties hereto of even date herewith (the "Securities Purchase  Agreement"),
the  Company has agreed,  upon the terms and  subject to the  conditions  of the
Securities  Purchase  Agreement,  to (i) issue and sell to the  Buyers (I) 3,000
shares of the  Company's  Series D1  Convertible  Preferred  Stock (the "Initial
Preferred  Shares"),  which will be convertible  into shares (as converted,  the
"Initial  Conversion Shares") of the Company's Common Stock, par value $0.01 per
share  (the  "Common  Stock" ), in  accordance  with the terms of the  Company's
Certificate of Amendment amending the Company's Certificate of Incorporation for
the designation of the Series D1 Convertible  Preferred Stock (the  "Certificate
of Amendment"),  and (II) a Warrant for each Initial  Preferred Share issued and
sold (collectively,  the "Initial Warrants") each of which Initial Warrants will
be exercisable to purchase up to a number of shares of Common Stock equal to the
quotient  of (A) 300,  divided by (B) the  average of the Closing Bid Prices (as
defined  in the  Certificate  of  Amendment)  of the  Common  Stock on the three
trading days  immediately  preceding the Initial Closing Date (as defined below)
(as exercised,  the "Initial  Warrant  Shares");  and (ii) issue and sell to the
Buyers  (I) 2,000  additional  shares  of the  Company's  Series D1  Convertible
Preferred Stock (the "Mandatory  Preferred  Shares" and  collectively,  with the
Initial Preferred  Shares,  the "Preferred  Shares"),  which will be convertible
into shares of Common Stock (as converted, the "Mandatory Conversion Shares" and
collectively with the Initial  Conversion  Shares,  the "Conversion  Shares") in
accordance  with the  Certificate  of  Amendment,  and (II) a  Warrant  for each
Mandatory  Preferred  Share  issued  and  sold  (collectively,   the  "Mandatory
Warrants" and collectively with the Initial Warrants,  the "Warrants"),  each of
which  Mandatory  Warrants  will be  exercisable  to  purchase up to a number of
shares of Common  Stock  equal to the  quotient  of (A) 300,  divided by (B) the
average of the Closing Bid Prices of the Common Stock on the three  trading days
immediately  preceding  the  Mandatory  Closing  Date  (as  defined  below)  (as
exercised,  the "Mandatory  Warrant  Shares" and  collectively  with the Initial
Warrant Shares, the "Warrant Shares");

         B. To induce the Buyers to execute and deliver the Securities  Purchase
Agreement,  the Company has agreed to provide certain  registration rights under
the  Securities  Act  of  1933,

<PAGE>

as amended, and the rules and regulations  thereunder,  or any similar successor
statute (collectively, the "1933 Act"), and applicable state securities laws.

         NOW,  THEREFORE,  in  consideration  of the  premises  and  the  mutual
covenants  contained  herein  and other  good and  valuable  consideration,  the
receipt and  sufficiency of which are hereby  acknowledged,  the Company and the
Buyers hereby agree as follows:

         1.       DEFINITIONS.

                  As used in this Agreement,  the following terms shall have the
following meanings:

                  a.  "Investor"  means a Buyer and any  transferee  or assignee
thereof  to whom such Buyer  assigns  its rights  under this  Agreement  and who
agrees to become bound by the  provisions of this  Agreement in accordance  with
Section 9.

                  b. "Person" means a corporation,  a limited liability company,
an association,  a partnership,  an organization,  a business, an individual,  a
governmental or political subdivision thereof or a governmental agency.

                  c. "Register,"  "registered,"  and  "registration"  refer to a
registration   effected  by  preparing  and  filing  one  or  more  Registration
Statements  (as defined  below) in compliance  with the 1933 Act and pursuant to
Rule 415  under  the 1933  Act or any  successor  rule  providing  for  offering
securities on a continuous or delayed basis ("Rule 415"), and the declaration or
ordering of effectiveness of such Registration Statement(s) by the United States
Securities and Exchange Commission (the "SEC").

                  d. "Registrable  Securities" means (i) the Initial  Conversion
Shares and the Mandatory Conversion Shares issued or issuable upon conversion of
the Initial Preferred Shares and the Mandatory Preferred Shares, as the case may
be, (ii) the Initial  Warrant Shares and the Mandatory  Warrant Shares issued or
issuable upon exercise of the Initial  Warrants and the Mandatory  Warrants,  as
the case may be, (iii) the  Dividend  Shares (as defined in the  Certificate  of
Amendment)  and (iv) any shares of capital stock issued or issuable with respect
to the Initial Conversion  Shares, the Mandatory  Conversion Shares, the Initial
Preferred Shares,  the Mandatory  Preferred Shares,  the Initial Warrant Shares,
the Mandatory Warrant Shares,  the Initial Warrants,  the Mandatory  Warrants or
the  Dividend   Shares  as  a  result  of  any  stock  split,   stock  dividend,
recapitalization,  exchange or similar event or otherwise, without regard to any
limitations  on  conversions  of  Preferred  Shares or  exercises  of  Warrants,
provided,  however,  the term  Registrable  Securities  shall  not  include  any
Registrable   Securities   which  have  been  sold   pursuant  to  an  effective
Registration  Statement (as defined  below) or pursuant to Rule 144  promulgated
under the 1933 Act.

<PAGE>

Additional Registrable Securities.

                  e. "Registration  Statement" means a registration statement or
registration statements of the Company filed under the 1933 Act.

Capitalized  terms used herein and not otherwise  defined  herein shall have the
respective meanings set forth in the Securities Purchase Agreement.

         2.       REGISTRATION.

                  a. Mandatory Registration.  The Company shall prepare, and, as
soon as practicable but in no event later than 45 days after the Initial Closing
Date (the "Filing  Deadline"),  file with the SEC the Registration  Statement on
Form S-3 covering the resale of all of the Initial  Registrable  Securities.  In
the event that Form S-3 is  unavailable  for such a  registration,  the  Company
shall use such other form as is available  for such a  registration,  subject to
the provisions of Section 2(e). The  Registration  Statement  prepared  pursuant
hereto shall  register for resale at least that number of shares of Common Stock
equal  to the  product  of (x) 2.0 and (y) the  number  of  Initial  Registrable
Securities  as  of  the  date   immediately   preceding  the  date  the  Initial
Registration  Statement  is  initially  filed with the SEC (as if the  Mandatory
Preferred Shares and the Mandatory  Warrants were issued and outstanding on such
date),  subject to adjustment as provided in Section 2(f). The Company shall use
its best efforts to have the Registration  Statement  declared  effective by the
SEC as soon as practicable, but in no event later than 90 days after the Initial
Closing Date (the "Effectiveness Deadline").

                  b. Piggy-Back Registrations.  If at any time prior to the date
on which the  Registration  Period (as hereinafter  defined) with respect to all
Registration Statements shall have expired, the number of shares of Common Stock
available for sale under the  Registration  Statements is  insufficient to cover
all of the Registrable  Securities and the Company proposes to file with the SEC
a  Registration  Statement  relating to an  offering  for its own account or the
account of others  under the 1933 Act of any of its  securities  (other  than on
Form S-4 or Form S-8 (or their  equivalents at such time) relating to securities
to be issued solely in connection with any acquisition of any entity or business
or equity securities  issuable in connection with stock option or other employee
benefit plans),  the Company shall promptly send to each Investor written notice
of  the  Company's  intention  to  file a  Registration  Statement  and of  such
Investor's  rights under this Section 2(b) and, if within ten (10) business days
after  receipt of such notice,  such Investor  shall so request in writing,  the
Company  shall  include in such  Registration  Statement  all or any part of the
Registrable  Securities such Investor requests to be registered,  subject to the
priorities  set forth below in this Section  2(b). No right to  registration  of
Registrable  Securities  under this Section 2(b) shall be construed to limit any
registration  required under Section 2(a). The  obligations of the Company under
this  Section  2(b)  may be  waived  by  Investors  holding  a  majority  of the
Registrable  Securities.  If an offering in

<PAGE>

connection with which an Investor is entitled to registration under this Section
2(b)  is  an  underwritten  offering,   then  each  Investor  whose  Registrable
Securities are included in such Registration  Statement shall,  unless otherwise
agreed  to by the  Company,  offer and sell such  Registrable  Securities  in an
underwritten offering using the same underwriter or underwriters and, subject to
the  provisions  of this  Agreement,  on the same terms and  conditions as other
shares of Common Stock included in such underwritten offering. If a registration
pursuant to this Section 2(b) is to be an  underwritten  public offering and the
managing  underwriter(s) advise the Company in writing, that in their reasonable
good faith opinion,  marketing or other factors dictate that a limitation on the
number of  shares of Common  Stock  which may be  included  in the  Registration
Statement is  advisable  to  facilitate  and not  adversely  affect the proposed
offering,  then the Company shall include in such  registration:  (1) first, all
securities the Company proposes to sell for its own account,  (2) second,  up to
the full number of securities  proposed to be registered  for the account of the
holders  of  securities  entitled  to  inclusion  of  their  securities  in  the
Registration  Statement by reason of demand registration  rights, and (3) third,
the securities  requested to be registered by the Investors and other holders of
securities  entitled to participate in the registration,  as of the date hereof,
drawn from them pro rata based on the number each has  requested  to be included
in such registration.

                  c. Allocation of Registrable Securities. The initial number of
Registrable  Securities included in any Registration Statement and each increase
in the number of Registrable  Securities included therein shall be allocated pro
rata among the Investors  based on the number of Registrable  Securities held by
each  Investor at the time the  Registration  Statement  covering  such  initial
number of Registrable  Securities or increase  thereof is declared  effective by
the SEC. In the event that an Investor sells or otherwise  transfers any of such
Investor's Registrable Securities, each transferee shall be allocated a pro rata
portion of the then remaining number of Registrable  Securities included in such
Registration Statement for such transferor.  Any shares of Common Stock included
in a  Registration  Statement  and which  remain  allocated  to any Person which
ceases to hold any Registrable Securities covered by such Registration Statement
shall be allocated to the remaining  Investors,  pro rata based on the number of
Registrable  Securities  then held by such  Investors  which are covered by such
Registration Statement.

                  d. Legal  Counsel.  Subject  to  Section 5 hereof,  the Buyers
holding a majority of the Registrable  Securities shall have the right to select
one legal counsel to review and oversee any offering  pursuant to this Section 2
("Legal Counsel"), which shall be Katten Muchin & Zavis or such other counsel as
thereafter   designated  by  the  holders  of  a  majority  of  the  Registrable
Securities.  The  Company  shall  reasonably  cooperate  with  Legal  Counsel in
performing the Company's obligations under this Agreement.

                  e.  Ineligibility  for Form S-3. In the event that Form S-3 is
not available for any  registration  of Registrable  Securities  hereunder,  the
Company  shall (i) register the sale of the  Registrable  Securities  on another
appropriate  form  reasonably  acceptable  to the  holders

<PAGE>

of a majority of the  Registrable  Securities and (ii) undertake to register the
Registrable  Securities on Form S-3 as soon as such form is available,  provided
that the Company shall maintain the effectiveness of the Registration  Statement
then in effect until such time as a Registration  Statement on Form S-3 covering
the Registrable Securities has been declared effective by the SEC.

                  f. Sufficient  Number of Shares  Registered.  In the event the
number of shares  available  under a  Registration  Statement  filed pursuant to
Section 2(a) is insufficient to cover all of the  Registrable  Securities  which
such  Registration  Statement  is required to cover or an  Investor's  allocated
portion of the  Registrable  Securities  pursuant to Section  2(c),  the Company
shall amend the Registration Statement, or file a new Registration Statement (on
the short form available  therefor,  if applicable),  or both, so as to cover at
least 200% of such  Registrable  Securities  (based on the  market  price of the
Common Stock on the trading day immediately preceding the date of filing of such
amendment or new Registration Statement),  in each case, as soon as practicable,
but in any event not later than fifteen (15) days after the  necessity  therefor
arises. The Company shall use it best efforts to cause such amendment and/or new
Registration  Statement to become effective as soon as practicable following the
filing thereof.  For purposes of the foregoing  provision,  the number of shares
available under a Registration  Statement shall be deemed "insufficient to cover
all of the  Registrable  Securities"  if at any time the  number of  Registrable
Securities  issued or  issuable  upon  conversion  of the  Preferred  Shares and
exercise of the Warrants covered by such Registration  Statement is greater than
the  quotient  determined  by dividing  (i) the number of shares of Common Stock
available for resale under such Registration Statement by (ii) 1.5. For purposes
of the calculation set forth in the foregoing sentence,  any restrictions on the
convertibility  of the  Preferred  Shares or exercise of the  Warrants  shall be
disregarded and such calculation shall assume that the Preferred Shares are then
convertible  into, and the Warrants are then  exercisable  for, shares of Common
Stock at the  then  prevailing  Conversion  Rate (as  defined  in the  Company's
Certificate  of  Amendment)  or  Exercise  Price (as  defined in the  Warrants),
respectively.

                  g.  Effect  of  Failure  to  File  and  Obtain  and   Maintain
Effectiveness  of  Registration  Statement.  If  (i)  a  Registration  Statement
covering all the Registrable  Securities and required to be filed by the Company
pursuant to this Agreement is not (A) filed with the SEC on or before the Filing
Deadline or (B)  declared  effective  by the SEC on or before the  Effectiveness
Deadline or (ii) on any day after the  Registration  Statement has been declared
effective  by the SEC sales of all the  Registrable  Securities  required  to be
included  on such  Registration  Statement  cannot be made (other than during an
Allowable   Grace  Period  (as  defined  in  Section  3(t)))   pursuant  to  the
Registration Statement (including,  without limitation,  because of a failure to
keep the Registration  Statement  effective,  to disclose such information as is
necessary  for  sales to be made  pursuant  to the  Registration  Statement,  to
register  sufficient  shares of Common  Stock),  then, as partial relief for the
damages to any holder by reason of any such delay in or reduction of its ability
to sell the  underlying  shares  of  Common

<PAGE>

Stock (which  remedy shall not be exclusive of any other  remedies  available at
law or in equity),  the Company shall pay to each holder of Preferred  Shares an
amount in cash per  Preferred  Share  held  equal to the  product  of (i) $1,000
multiplied  by (ii) the sum of (A) .02,  if the  Registration  Statement  is not
filed by the Filing Deadline, plus (B) .02, if the Registration Statement is not
declared effective by the Effectiveness  Deadline,  plus, (C) the product of (I)
 .000667  multiplied  by (II) the sum of (x) the  number of days after the Filing
Deadline  that such  Registration  Statement is not filed with the SEC, plus (y)
the  number  of days  after the  Effectiveness  Deadline  that the  Registration
Statement  is not  declared  effective  by the SEC,  plus (z) the number of days
after the  Registration  Statement has been  declared  effective by the SEC that
such  Registration  Statement is not  available  (other than during an Allowable
Grace Period) for the sale of at least all the Registrable  Securities  required
to be included on such  Registration  Statement.  The payments to which a holder
shall be  entitled  pursuant  to this  Section  2(g) are  referred  to herein as
"Registration Delay Payments."  Registration Delay Payments shall be paid on the
earlier of (I) the last day of the calendar month during which such Registration
Delay  Payments are incurred and (II) the third  business day after the event or
failure giving rise to the Registration  Delayed Payments is cured. In the event
the Company fails to make Registration  Delay Payments in a timely manner,  such
Registration  Delay  Payments  shall bear interest at the rate of 2.0% per month
(prorated for partial months) until paid in full.

         3.       RELATED OBLIGATIONS.

         Whenever an Investor has requested that any  Registrable  Securities be
registered  pursuant to Section 2(b) or at such time as the Company is obligated
to file a Registration Statement with the SEC pursuant to Sections 2(a) or 2(f),
the  Company  will  use its best  efforts  to  effect  the  registration  of the
Registrable  Securities in accordance  with the intended  method of  disposition
thereof and, pursuant thereto, the Company shall have the following obligations:

                  a. The Company shall promptly  prepare and file with the SEC a
Registration  Statement  with respect to the applicable  Registrable  Securities
(but in no event  later than the Filing  Deadline)  and use its best  efforts to
cause such  Registration  Statement  relating to the  Registrable  Securities to
become effective as soon as practicable after such filing (but in no event later
than the  Effectiveness  Deadline).  The  Company  shall keep each  Registration
Statement  effective  pursuant to Rule 415 at all times until the earlier of (i)
the date as of which the  Investors may sell all of the  Registrable  Securities
covered by such  Registration  Statement  without  restriction  pursuant to Rule
144(k) (or successor thereto) promulgated under the 1933 Act or (ii) the date on
which the Investors  shall have sold all the Registrable  Securities  covered by
such Registration  Statement (the  "Registration  Period"),  which  Registration
Statement  (including  any amendments or  supplements  thereto and  prospectuses
contained  therein) shall not contain any untrue statement of a material fact or
omit to state a material  fact  required to be stated  therein,  or necessary to
make the statements  therein,  in light of the  circumstances in which they were
made, not  misleading.  The term

<PAGE>

"best efforts" shall mean, among other things,  that the Company shall submit to
the SEC, within three (3) business days (except such period shall be extended to
ten  (10)  business  days  if  there  exists  material  non-public   information
concerning  the Company the  disclosure of which at the time is not, in the good
faith  opinion of the Board of Directors of the Company and its counsel,  in the
best  interest  of the  Company)  after the  Company  learns that no review of a
particular  Registration  Statement will be made by the staff of the SEC or that
the staff has no further comments on the Registration Statement, as the case may
be, a request for acceleration of effectiveness of such  Registration  Statement
to a time and date not later than 48 hours after the submission of such request.

                  b.  The  Company  shall  prepare  and  file  with the SEC such
amendments   (including   post-effective   amendments)   and  supplements  to  a
Registration   Statement  and  the  prospectus  used  in  connection  with  such
Registration  Statement,  which  prospectus is to be filed  pursuant to Rule 424
promulgated  under the 1933 Act, as may be necessary  to keep such  Registration
Statement  effective at all times during the  Registration  Period,  and, during
such  period,  comply with the  provisions  of the 1933 Act with  respect to the
disposition  of all  Registrable  Securities  of the  Company  covered  by  such
Registration  Statement  until such time as all of such  Registrable  Securities
shall  have  been  disposed  of in  accordance  with  the  intended  methods  of
disposition by the seller or sellers  thereof as set forth in such  Registration
Statement. In the case of amendments and supplements to a Registration Statement
which are required to be filed pursuant to this Agreement (including pursuant to
this Section 3(b)) by reason of the Company  filing a report on Form 10-K,  Form
10-Q or Form 8-K or any analogous  report under the  Securities  Exchange Act of
1934,  as amended (the "1934 Act"),  the Company  shall have  incorporated  such
report by reference into the  Registration  Statement,  if applicable,  or shall
file such  amendments or  supplements  with the SEC on the same day on which the
1934 Act report is filed which created the  requirement for the Company to amend
or supplement the Registration Statement.

                  c. The Company  shall (a) permit  Legal  Counsel to review and
comment upon (i) the Registration  Statement at least five (5) days prior to its
filing  with  the  SEC  and  (ii)  all  other  Registration  Statements  and all
amendments and  supplements to all  Registration  Statements  (except for Annual
Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form
8-K and any similar or successor  reports)  within a  reasonable  number of days
prior to the their  filing with the SEC and (b) not file any  document in a form
to which Legal Counsel  reasonably objects in a timely manner. The Company shall
not submit a request for  acceleration  of the  effectiveness  of a Registration
Statement or any amendment or supplement  thereto  without the prior approval of
Legal  Counsel,  which consent  shall not be withheld,  unless legal counsel has
objected  to  disclosures  in the  Registration  Statement  relating  to (A) the
Registrable  Securities,  the  Preferred  Shares  or the  Warrants  or  (B)  the
Investors.  The Company shall furnish to Legal Counsel,  without charge, (i) any
correspondence  from  the  SEC or the  staff  of the SEC to the  Company  or its
representatives relating to any Registration Statement, (ii) promptly after

<PAGE>

the same is  prepared  and  filed  with the  SEC,  one copy of any  Registration
Statement and any  amendment(s)  thereto,  including  financial  statements  and
schedules,  all documents incorporated therein by reference and all exhibits and
(iii) upon the  effectiveness  of any  Registration  Statement,  one copy of the
prospectus  included  in such  Registration  Statement  and all  amendments  and
supplements thereto.

                  d.  The  Company  shall   furnish  to  each   Investor   whose
Registrable  Securities  are  included in any  Registration  Statement,  without
charge, (i) promptly after the same is prepared and filed with the SEC, at least
one copy of such Registration Statement and any amendment(s) thereto,  including
financial  statements  and  schedules,  all  documents  incorporated  therein by
reference,  all  exhibits  and  each  preliminary  prospectus,   (ii)  upon  the
effectiveness of any Registration  Statement,  ten (10) copies of the prospectus
included in such  Registration  Statement  and all  amendments  and  supplements
thereto (or such other number of copies as such Investor may reasonably request)
and (iii) such other  documents,  including  copies of any  preliminary or final
prospectus,  as such Investor may reasonably  request from time to time in order
to  facilitate  the  disposition  of the  Registrable  Securities  owned by such
Investor.

                  e. The Company  shall use its best efforts to (i) register and
qualify,  unless an exemption from registration and qualification  applies,  the
Registrable  Securities  covered  by a  Registration  Statement  under all other
securities or "blue sky" laws of such  jurisdictions in the United States,  (ii)
prepare   and  file  in  those   jurisdictions,   such   amendments   (including
post-effective   amendments)   and   supplements  to  such   registrations   and
qualifications as may be necessary to maintain the effectiveness  thereof during
the  Registration  Period,  (iii) take such other actions as may be necessary to
maintain such registrations and qualifications in effect at all times during the
Registration  Period,  and (iv) take all other actions  reasonably  necessary or
advisable to qualify the Registrable  Securities for sale in such jurisdictions;
provided,  however,  that  the  Company  shall  not be  required  in  connection
therewith  or as a  condition  thereto  to (x)  qualify  to do  business  in any
jurisdiction  where it would not  otherwise  be required to qualify but for this
Section 3(e), (y) subject itself to general  taxation in any such  jurisdiction,
or (z) file a general  consent to  service of process in any such  jurisdiction.
The Company  shall  promptly  notify Legal  Counsel and each  Investor who holds
Registrable  Securities of the receipt by the Company of any  notification  with
respect to the suspension of the  registration  or  qualification  of any of the
Registrable  Securities  for sale under the securities or "blue sky" laws of any
jurisdiction  in the  United  States  or its  receipt  of  actual  notice of the
initiation or threatening of any proceeding for such purpose.

                  f. As promptly as  practicable  after  becoming  aware of such
event or  development,  the Company shall notify Legal Counsel and each Investor
in writing  of the  happening  of any event as a result of which the  prospectus
included  in a  Registration  Statement,  as then in effect,  includes an untrue
statement of a material fact or omission to state a material fact required to be
stated  therein or necessary  to make the  statements  therein,  in

<PAGE>

light of the  circumstances  under  which they were made,  not  misleading,  and
promptly  prepare a supplement  or amendment to such  Registration  Statement to
correct such untrue  statement or omission,  and deliver ten (10) copies of such
supplement or amendment to Legal Counsel and each Investor (or such other number
of copies as Legal Counsel or such Investor may reasonably request). The Company
shall also promptly notify Legal Counsel and each Investor in writing (i) when a
prospectus or any  prospectus  supplement or  post-effective  amendment has been
filed,  and when a Registration  Statement or any  post-effective  amendment has
become effective (notification of such effectiveness shall be delivered to Legal
Counsel and each  Investor by facsimile on the same day of such  effectiveness),
(ii) of any request by the SEC for  amendments or  supplements to a Registration
Statement  or  related  prospectus  or  related  information,  and  (iii) of the
Company's  reasonable   determination  that  a  post-effective  amendment  to  a
Registration Statement would be appropriate.

                  g. The  Company  shall use its best  efforts  to  prevent  the
issuance  of  any  stop  order  or  other   suspension  of  effectiveness  of  a
Registration  Statement,  or the suspension of the  qualification  of any of the
Registrable  Securities  for sale in any  jurisdiction  and, if such an order or
suspension  is issued,  to obtain the  withdrawal of such order or suspension as
soon as  possible  and to  notify  Legal  Counsel  and each  Investor  who holds
Registrable  Securities  being  sold  of the  issuance  of  such  order  and the
resolution  thereof or its receipt of actual notice of the  initiation or threat
of any proceeding for such purpose.

                  h. At the  reasonable  request of any  Investor,  the  Company
shall  furnish  to  such  Investor,  on the  date  of the  effectiveness  of the
Registration  Statement  and  thereafter  from time to time on such  dates as an
Investor  may  reasonably  request  (i) a  letter,  dated  such  date,  from the
Company's  independent  certified public accountants in form and substance as is
customarily given by independent certified public accountants to underwriters in
an underwritten public offering,  and (ii) an opinion, dated as of such date, of
counsel representing the Company for purposes of such Registration Statement, in
form,  scope and substance as is  customarily  given in an  underwritten  public
offering, addressed to the Investors.

                  i. The Company shall make  available for inspection by (i) any
Investor,  (ii) Legal Counsel and (iii) one firm of  accountants or other agents
retained by the  Investors,  (collectively,  the  "Inspectors"),  all  pertinent
financial and other records, and pertinent corporate documents and properties of
the  Company  (collectively,  the  "Records"),  as  shall be  reasonably  deemed
necessary by each  Inspector,  and cause the Company's  officers,  directors and
employees to supply all information which any Inspector may reasonably  request;
provided,  however,  that each Inspector  shall agree,  and each Investor hereby
agrees, to hold in strict  confidence and shall not make any disclosure  (except
to an  Investor)  or use of any Record or other  information  which the  Company
determines  in good faith to be  confidential,  and of which  determination  the
Inspectors  and  Investors  are so notified,  unless (a) the  disclosure of such
Records is  necessary  to avoid or correct a  misstatement  or  omission  in any
Registration  Statement  or is  otherwise  required  under the 1933 Act, (b) the
release of such

<PAGE>

Records is ordered pursuant to a final,  non-appealable subpoena or order from a
court or government  body of competent  jurisdiction,  or (c) the information in
such  Records  has been made  generally  available  to the public  other than by
disclosure  in violation of this or any other  agreement of which the  Inspector
has  knowledge.  The Company shall not be required to disclose any  confidential
information  in such Records to any  Inspector  until and unless such  Inspector
shall have entered into confidentiality agreements with the Company with respect
thereto,  substantially  in the form of this Section 3(i).  Each Investor agrees
that it shall,  upon learning that disclosure of such Records is sought in or by
a court or governmental  body of competent  jurisdiction or through other means,
give prompt written notice to the Company and allow the Company, at its expense,
to  undertake  appropriate  action  to  prevent  disclosure  of,  or to obtain a
protective order for, the Records deemed confidential.

                  j.  The  Company  shall  hold in  confidence  and not make any
disclosure of information  concerning an Investor provided to the Company unless
(i) disclosure of such  information is necessary to comply with federal or state
securities  laws, (ii) the disclosure of such  information is necessary to avoid
or correct a misstatement or omission in any Registration  Statement,  (iii) the
release of such  information  is ordered  pursuant to a subpoena or other final,
non-appealable   order  from  a  court  or   governmental   body  of   competent
jurisdiction,  or (iv) such information has been made generally available to the
public other than by  disclosure  in  violation  of this  Agreement or any other
agreement  or (v) such  Investor  consents  to the form and  content of any such
disclosure.  The Company agrees that it shall,  upon learning that disclosure of
such  information  concerning  an  Investor  is  sought  in  or  by a  court  or
governmental body of competent  jurisdiction or through other means, give prompt
written  notice to such  Investor  and allow such  Investor,  at the  Investor's
expense, to undertake  appropriate action to prevent disclosure of, or to obtain
a protective order for, such information.

                  k. The Company shall use its best efforts  either to (i) cause
all the Registrable  Securities covered by a Registration Statement to be listed
on each  securities  exchange  on which  securities  of the same class or series
issued  by the  Company  are  then  listed,  if  any,  if the  listing  of  such
Registrable  Securities is then permitted  under the rules of such exchange,  or
(ii) secure designation and quotation of all the Registrable  Securities covered
by the  Registration  Statement  on the  Nasdaq  SmallCap  Market,  or (iii) if,
despite the Company's best efforts to satisfy the preceding  clause (i) or (ii),
the Company is unsuccessful  in satisfying the preceding  clause (i) or (ii), to
secure the inclusion for  reporting on the Over the Counter  Bulletin  Board for
such  Registrable  Securities  and,  without  limiting  the  generality  of  the
foregoing,  to  arrange  for at least two  market  makers to  register  with the
National  Association of Securities Dealers,  Inc. ("NASD") as such with respect
to such Registrable  Securities.  The Company shall pay all fees and expenses in
connection with satisfying its obligation under this Section 3(k).

                  l. The Company  shall  cooperate  with the  Investors who hold
Registrable

<PAGE>

Securities being offered,  and to the extent applicable to facilitate the timely
preparation  and delivery of certificates  (not bearing any restrictive  legend)
representing the Registrable Securities to be offered pursuant to a Registration
Statement and enable such  certificates to be in such  denominations or amounts,
as the case may be, as the Investors may  reasonably  request and  registered in
such names as the Investors may request.

                  m. The Company shall provide a transfer agent and registrar of
all  such  Registrable  Securities  not  later  than the  effective  date of the
applicable Registration Statement.

                  n. If requested by an Investor,  the Company shall (i) as soon
as  practicable   incorporate  in  a  prospectus  supplement  or  post-effective
amendment  such  information as such Investor  reasonably  requested be included
therein  relating  to the  sale  and  distribution  of  Registrable  Securities,
including,  without  limitation,  information  with  respect  to the  number  of
Registrable  Securities  being  offered or sold,  the purchase  price being paid
therefor and any other terms of the offering of the Registrable Securities to be
sold in such offering;  (ii) as soon as reasonably practicable make all required
filings of such prospectus  supplement or  post-effective  amendment after being
notified of the matters to be  incorporated  in such  prospectus  supplement  or
post-effective  amendment;  and  (iii)  supplement  or  make  amendments  to any
Registration  Statement  if  reasonably  requested  by  such  Investor  of  such
Registrable Securities.

                  o. The  Company  shall  use its  best  efforts  to  cause  the
Registrable  Securities covered by the applicable  Registration  Statement to be
registered with or approved by such other  governmental  agencies or authorities
as  may  be  necessary  to  consummate  the  disposition  of  such   Registrable
Securities.

                  p. The Company shall make generally  available to its security
holders as soon as practical,  but not later than 90 days after the close of the
period  covered  thereby,  an earnings  statement  (in form  complying  with the
provisions  of Rule 158 under  the 1933  Act)  covering  a  twelve-month  period
beginning  not later than the first day of the  Company's  fiscal  quarter  next
following the effective date of the Registration Statement.

                  q. The Company shall  otherwise use its best efforts to comply
with all  applicable  rules and  regulations  of the SEC in connection  with any
registration hereunder.

                  r. Within two (2) business days after a Registration Statement
which covers applicable  Registrable Securities is ordered effective by the SEC,
the Company  shall  deliver,  and shall  cause legal  counsel for the Company to
deliver,  to the transfer agent for such Registrable  Securities (with copies to
the Investors  whose  Registrable  Securities are included in such  Registration
Statement)  confirmation  that such  Registration  Statement  has been  declared
effective by the SEC in the form attached hereto as Exhibit A.

<PAGE>

                  s.  Intentionally Left Blank.

                  t.  Notwithstanding  anything to the contrary in Section 3(f),
at any time  after  the  applicable  Registration  Statement  has been  declared
effective  by the  SEC,  the  Company  may  delay  the  disclosure  of  material
non-public  information  concerning  the Company the  disclosure of which at the
time is not, in the good faith  opinion of the Board of Directors of the Company
and its  counsel,  in the best  interest of the  Company  and, in the opinion of
counsel to the Company,  otherwise required (a "Grace Period");  provided,  that
the Company shall  promptly (i) notify the Investors in writing of the existence
of material non-public  information giving rise to a Grace Period (provided that
in each  notice the  Company  will not  disclose  the  content of such  material
non-public  information to the Investors) and the date on which the Grace Period
will begin,  and (ii) notify the  Investors  in writing of the date on which the
Grace Period ends; and, provided further,  that no Grace Periods shall exceed 10
consecutive  days and during any consecutive  365 day period,  there shall be no
more than two (2) Grace Periods (an "Allowable  Grace Period").  For purposes of
determining the length of a Grace Period above,  the Grace Period shall begin on
and include the date the  holders  receive the notice  referred to in clause (i)
and  shall end on and  include  the later of the date the  holders  receive  the
notice  referred to in clause (ii) and the date referred to in such notice.  The
provisions  of 3(g)  hereof  shall not be  applicable  during  the period of any
Allowable Grace Period.  Upon expiration of the Grace Period,  the Company shall
again be bound by the  first  sentence  of  Section  3(f)  with  respect  to the
information giving rise thereto unless such material  non-public  information is
no longer applicable.

         4.       OBLIGATIONS OF THE INVESTORS.

                  a. At least  seven  (7) days  prior to the  first  anticipated
filing date of a Registration Statement,  the Company shall notify each Investor
in writing of the  information  the Company  requires from each such Investor if
such  Investor  elects  to have any of such  Investor's  Registrable  Securities
included in such Registration  Statement.  It shall be a condition  precedent to
the  obligations  of the Company to complete the  registration  pursuant to this
Agreement with respect to the  Registrable  Securities of a particular  Investor
that such  Investor  shall  furnish to the Company  such  information  regarding
itself,  the  Registrable  Securities  held by it and  the  intended  method  of
disposition  of the  Registrable  Securities  held by it as shall be  reasonably
required to effect the  registration  of such  Registrable  Securities and shall
execute such documents in connection  with such  registration as the Company may
reasonably request.

                  b.  Each  Investor,  by  such  Investor's  acceptance  of  the
Registrable  Securities,  agrees to  cooperate  with the  Company as  reasonably
requested by the Company in connection  with the  preparation  and filing of any
Registration Statement hereunder,  unless such Investor has notified the Company
in  writing  of such  Investor's  election  to  exclude  all of such  Investor's
Registrable Securities from such Registration Statement.

<PAGE>

                  c. Each Investor  agrees that, upon receipt of any notice from
the Company of the happening of any event of the kind described in Section 3(g),
the first sentence of 3(f) or 3(s), such Investor will  immediately  discontinue
disposition of Registrable Securities pursuant to any Registration  Statement(s)
covering such Registrable Securities until such Investor's receipt of the copies
of the  supplemented or amended  prospectus  contemplated by Section 3(g) or the
first  sentence of 3(f) or receipt of notice that no  supplement or amendment is
required.  Notwithstanding anything to the contrary, the Company shall cause its
transfer agent to deliver  unlegended  shares of Common Stock to a transferee of
an Investor in accordance with the terms of the Securities Purchase Agreement in
connection  with any sale of  Registrable  Securities  with  respect to which an
Investor has entered into a contract for sale prior to the Investor's receipt of
a notice from the Company of the happening of any event of the kind described in
Section  3(g) or the first  sentence of 3(f) and for which the  Investor has not
yet settled.

         5.       EXPENSES OF REGISTRATION.

                  All reasonable expenses, other than underwriting discounts and
commissions,   incurred   in   connection   with   registrations,   filings   or
qualifications pursuant to Sections 2 and 3, including,  without limitation, all
registration,  listing and  qualifications  fees,  printers and accounting  fees
shall be paid by the Company. Subject to Section 4(i) of the Securities Purchase
Agreement,  the Company shall not be responsible for the fees and  disbursements
of Legal  Counsel in connection  with  registration,  filings or  qualifications
pursuant to Sections 2 and 3 of this Agreement.

         6.       INDEMNIFICATION.

                  In the event any  Registrable  Securities  are  included  in a
Registration Statement under this Agreement:

                  a. To the fullest  extent  permitted by law, the Company will,
and hereby  does,  indemnify,  hold  harmless  and  defend  each  Investor,  the
directors,  officers, partners, employees, agents,  representatives of, and each
Person,  if any, who controls any Investor within the meaning of the 1933 Act or
the Securities  and Exchange Act of 1934 as amended (the "1934 Act ") (each,  an
"Indemnified  Person"),  against  any  losses,  claims,  damages,   liabilities,
judgments, fines, penalties, charges, costs, reasonable attorneys' fees, amounts
paid in  settlement  or  expenses,  joint or several,  (collectively,  "Claims")
incurred in  investigating,  preparing or  defending  any action,  claim,  suit,
inquiry,  proceeding,  investigation  or appeal  taken from the  foregoing by or
before any court or governmental,  administrative  or other  regulatory  agency,
body or the SEC,  whether  pending or threatened,  whether or not an indemnified
party is or may be a party thereto ("Indemnified Damages"), to which any of them
may become subject  insofar as such Claims (or actions or  proceedings,  whether
commenced or threatened, in respect thereof) arise out of or are based upon: (i)
any  untrue

<PAGE>

statement  or alleged  untrue  statement  of a material  fact in a  Registration
Statement  or any  post-effective  amendment  thereto or in any  filing  made in
connection with the  qualification of the offering under the securities or other
"blue sky" laws of any jurisdiction in which Registrable  Securities are offered
("Blue Sky  Filing"),  or the  omission or alleged  omission to state a material
fact required to be stated therein or necessary to make the  statements  therein
not  misleading,  (ii) any untrue  statement  or alleged  untrue  statement of a
material  fact  contained  in any  preliminary  prospectus  if used prior to the
effective  date  of such  Registration  Statement,  or  contained  in the  final
prospectus  (as  amended or  supplemented,  if the Company  files any  amendment
thereof or supplement  thereto with the SEC) or the omission or alleged omission
to state  therein  any  material  fact  necessary  to make the  statements  made
therein,  in light of the circumstances  under which the statements therein were
made, not misleading or (iii) any violation or alleged  violation by the Company
of the 1933 Act, the 1934 Act, any other law, including, without limitation, any
state securities law, or any rule or regulation thereunder relating to the offer
or sale of the Registrable  Securities pursuant to a Registration Statement (the
matters  in  the  foregoing  clauses  (i)  through  (iii)  being,  collectively,
"Violations").  Subject  to  Section  6(c),  the  Company  shall  reimburse  the
Investors  and each such  controlling  Person,  promptly  as such  expenses  are
incurred and are due and payable, for any reasonable legal fees or disbursements
or other reasonable  expenses incurred by them in connection with  investigating
or defending any such Claim.  Notwithstanding anything to the contrary contained
herein, the indemnification  agreement contained in this Section 6(a): (i) shall
not apply to a Claim by an  Indemnified  Person  arising  out of or based upon a
Violation  which  occurs in reliance  upon and in  conformity  with  information
furnished in writing to the Company by such Indemnified Person expressly for use
in connection  with the  preparation of the  Registration  Statement or any such
amendment  thereof or supplement  thereto,  if such  prospectus  was timely made
available by the Company  pursuant to Section 3(d);  (ii) shall not be available
to the extent such Claim is based on a failure of the  Investor to deliver or to
cause to be delivered  the  prospectus  made  available by the Company,  if such
prospectus  was timely made  available by the Company  pursuant to Section 3(d);
and (iii)  shall not apply to amounts  paid in  settlement  of any Claim if such
settlement is effected  without the prior written consent of the Company,  which
consent shall not be unreasonably withheld.  Such indemnity shall remain in full
force and effect  regardless  of any  investigation  made by or on behalf of the
Indemnified Person and shall survive the transfer of the Registrable  Securities
by the Investors pursuant to Section 9.

                  b. In connection with any  Registration  Statement in which an
Investor  is  participating,  each such  Investor  agrees to  severally  and not
jointly indemnify,  hold harmless and defend, to the same extent and in the same
manner as is set forth in Section 6(a), the Company, each of its directors, each
of its officers who signs the  Registration  Statement and each Person,  if any,
who  controls  the  Company  within the  meaning of the 1933 Act or the 1934 Act
(each an "Indemnified Party"), against any Claim or Indemnified Damages to which
any of them may become  subject,  under the 1933 Act, the 1934 Act or otherwise,
insofar as such Claim or Indemnified  Damages arise out of or are based upon any
Violation,  in each  case

<PAGE>

to the extent,  and only to the extent,  that such Violation  occurs in reliance
upon and in conformity with written information furnished to the Company by such
Investor expressly for use in connection with such Registration Statement;  and,
subject  to  Section  6(c),  such  Investor  will  reimburse  any legal or other
expenses  reasonably  incurred  by  them in  connection  with  investigating  or
defending  any such  Claim;  provided,  however,  that the  indemnity  agreement
contained in this Section 6(b) and the  agreement  with respect to  contribution
contained  in Section 7 shall not apply to  amounts  paid in  settlement  of any
Claim if such  settlement is effected  without the prior written consent of such
Investor, which consent shall not be unreasonably withheld;  provided,  further,
however, that the Investor shall be liable under this Section 6(b) for only that
amount of a Claim or Indemnified  Damages as does not exceed the net proceeds to
such Investor as a result of the sale of Registrable Securities pursuant to such
Registration  Statement.  Such  indemnity  shall remain in full force and effect
regardless of any  investigation  made by or on behalf of such Indemnified Party
and shall  survive the transfer of the  Registrable  Securities by the Investors
pursuant  to Section  9.  Notwithstanding  anything  to the  contrary  contained
herein,  the  indemnification  agreement  contained  in this  Section  6(b) with
respect to any  prospectus  shall not inure to the  benefit  of any  Indemnified
Party if the untrue  statement  or omission of material  fact  contained  in the
prospectus was corrected on a timely basis in the prospectus, as then amended or
supplemented.

                  c.  Promptly  after  receipt  by  an  Indemnified   Person  or
Indemnified  Party  under this  Section 6 of notice of the  commencement  of any
action or proceeding (including any governmental action or proceeding) involving
a Claim,  such  Indemnified  Person or  Indemnified  Party shall,  if a Claim in
respect thereof is to be made against any indemnifying  party under this Section
6,  deliver  to the  indemnifying  party a written  notice  of the  commencement
thereof, and the indemnifying party shall have the right to participate in, and,
to the  extent  the  indemnifying  party so  desires,  jointly  with  any  other
indemnifying party similarly  noticed,  to assume control of the defense thereof
with counsel mutually satisfactory to the indemnifying party and the Indemnified
Person or the Indemnified Party, as the case may be; provided,  however, that an
Indemnified  Person or Indemnified  Party shall have the right to retain its own
counsel  with the fees  and  expenses  of not  more  than one  counsel  for such
Indemnified  Person or Indemnified  Party to be paid by the indemnifying  party,
if, in the reasonable opinion of counsel retained by the indemnifying party, the
representation  by such counsel of the Indemnified  Person or Indemnified  Party
and the  indemnifying  party would be  inappropriate  due to actual or potential
differing interests between such Indemnified Person or Indemnified Party and any
other party  represented by such counsel in such  proceeding.  In the case of an
Indemnified  Person,  legal  counsel  referred to in the  immediately  preceding
sentence  shall be selected by the  Investors  holding a majority in interest of
the Registrable  Securities included in the Registration  Statement to which the
Claim relates. The Indemnified Party or Indemnified Person shall cooperate fully
with the indemnifying party in connection with any negotiation or defense of any
such  action  or  Claim by the  indemnifying  party  and  shall  furnish  to the
indemnifying party all information reasonably available to the Indemnified Party
or Indemnified  Person which relates to such action or Claim.  The  indemnifying
party shall keep

<PAGE>

the  Indemnified  Party or Indemnified  Person fully apprised at all times as to
the status of the defense or any settlement  negotiations  with respect thereto.
No indemnifying party shall be liable for any settlement of any action, claim or
proceeding effected without its prior written consent,  provided,  however, that
the indemnifying party shall not unreasonably  withhold,  delay or condition its
consent.  No indemnifying party shall,  without the prior written consent of the
Indemnified  Party or  Indemnified  Person,  consent to entry of any judgment or
enter into any  settlement  or other  compromise  which  does not  include as an
unconditional  term  thereof  the giving by the  claimant or  plaintiff  to such
Indemnified  Party or  Indemnified  Person of a release  from all  liability  in
respect to such Claim or litigation.  Following  indemnification as provided for
hereunder,  the  indemnifying  party  shall be  subrogated  to all rights of the
Indemnified Party or Indemnified Person with respect to all third parties, firms
or corporations  relating to the matter for which indemnification has been made.
The  failure  to  deliver  written  notice to the  indemnifying  party  within a
reasonable  time of the  commencement  of any such action shall not relieve such
indemnifying  party of any liability to the  Indemnified  Person or  Indemnified
Party under this Section 6, except to the extent that the indemnifying  party is
prejudiced in its ability to defend such action.

                  d. The  indemnification  required  by this  Section 6 shall be
made by  periodic  payments  of the  amount  thereof  during  the  course of the
investigation or defense,  as and when bills are received or Indemnified Damages
are incurred.

                  e.  The  indemnity  agreements  contained  herein  shall be in
addition to (i) any cause of action or similar right of the Indemnified Party or
Indemnified  Person  against  the  indemnifying  party or  others,  and (ii) any
liabilities the indemnifying party may be subject to pursuant to the law.

         7.       CONTRIBUTION.

                  To the extent any  indemnification by an indemnifying party is
prohibited or limited by law, the indemnifying  party agrees to make the maximum
contribution  with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; provided, however, that:
(i) no seller of Registrable  Securities guilty of fraudulent  misrepresentation
(within  the  meaning of Section  11(f) of the 1933 Act)  shall be  entitled  to
contribution  from any seller of  Registrable  Securities  who was not guilty of
fraudulent misrepresentation; and (ii) contribution by any seller of Registrable
Securities shall be limited in amount to the net amount of proceeds  received by
such seller from the sale of such Registrable Securities.

         8.       REPORTS UNDER THE 1934 ACT.

                  With a view to making  available to the Investors the benefits
of Rule  144  promulgated  under  the  1933  Act or any  other  similar  rule or
regulation  of the  SEC  that  may at

<PAGE>

any time permit the  Investors to sell  securities  of the Company to the public
without registration ("Rule 144"), the Company agrees to:

                  a. make and keep public information available,  as those terms
are understood and defined in Rule 144;

                  b. file with the SEC in a timely  manner all reports and other
documents required of the Company under the 1933 Act and the 1934 Act so long as
the Company  remains  subject to such  requirements  (it being  understood  that
nothing herein shall limit the Company's  obligations  under Section 4(c) of the
Securities  Purchase  Agreement)  and the  filing  of  such  reports  and  other
documents is required for the applicable provisions of Rule 144; and

                  c.  furnish to each  Investor  so long as such  Investor  owns
Registrable  Securities,  promptly upon request,  (i) a written statement by the
Company that it has complied  with the reporting  requirements  of Rule 144, the
1933 Act and the 1934 Act,  (ii) a copy of the most recent  annual or  quarterly
report of the  Company  and such other  reports  and  documents  so filed by the
Company,  and (iii) such other  information  as may be  reasonably  requested to
permit  the  Investors  to sell such  securities  pursuant  to Rule 144  without
registration.

         9.       ASSIGNMENT OF REGISTRATION RIGHTS.

                  The  rights  under  this  Agreement  shall  be   automatically
assignable  by the  Investors  to any  transferee  of  all  or  any  portion  of
Registrable  Securities  if:  (i)  the  Investor  agrees  in  writing  with  the
transferee  or assignee to assign such rights,  and a copy of such  agreement is
furnished to the Company within a reasonable  time after such  assignment;  (ii)
the Company is,  within a  reasonable  time after such  transfer or  assignment,
furnished with written notice of (a) the name and address of such  transferee or
assignee,  and (b)  the  Registrable  Securities  with  respect  to  which  such
registration  rights  are  being  transferred  or  assigned;  (iii)  immediately
following such transfer or assignment the further disposition of such securities
by the  transferee or assignee is restricted  under the 1933 Act and  applicable
state  securities  laws;  (iv) at or before the time the  Company  receives  the
written  notice  contemplated  by clause (ii) of this sentence the transferee or
assignee agrees in writing with the Company to be bound by all of the provisions
contained herein;  and (v) such transfer shall have been made in accordance with
the applicable requirements of the Securities Purchase Agreement.

         10.      AMENDMENT OF REGISTRATION RIGHTS.

                  Provisions of this Agreement may be amended and the observance
thereof may be waived (either  generally or in a particular  instance and either
retroactively  or  prospectively),  only with the written consent of the Company
and  Investors  who then  hold at  least  two-thirds  (2/3)  of the  Registrable
Securities.  Any amendment or waiver effected in accordance with this Section 10
shall be binding upon each Investor and the Company.  No such amendment shall be
effective  to the extent  that it applies to less than all of the holders of the
Registrable Securities.  No

<PAGE>

consideration  shall be  offered  or paid to any Person to amend or consent to a
waiver or modification of any provision of any of this Agreement unless the same
consideration also is offered to all of the parties to this Agreement.

         11.      MISCELLANEOUS.

                  a. A Person is deemed to be a holder of Registrable Securities
whenever  such  Person  owns or is  deemed  to own of  record  such  Registrable
Securities.  If  the  Company  receives  conflicting  instructions,  notices  or
elections  from  two or  more  Persons  with  respect  to the  same  Registrable
Securities,  the  Company  shall act upon the basis of  instructions,  notice or
election received from the registered owner of such Registrable Securities.

                  b. Any  notices,  consents,  waivers  or other  communications
required or permitted to be given under the terms of this  Agreement  must be in

         Re:      Cyber Digital, Inc.

Ladies and Gentlemen:

         We are counsel to Cyber  Digital,  Inc.,  a New York  corporation  (the
"Company"),  and have  represented  the Company in connection  with that certain
Securities  Purchase  Agreement (the "Purchase  Agreement")  entered into by and
among the Company and the buyers named therein  (collectively,  the  "Holders"),
pursuant  to which the  Company  issued to the  Holders  shares of its Series D1
Convertible Preferred Stock, par value $0.05 per share (the "Preferred Shares"),
convertible into shares of the Company's Common Stock, par value $0.01 per share
(the "Common Stock"),  and Warrants (the "Warrants") to acquire shares of Common
Stock.  Pursuant to the  Purchase  Agreement,  the Company also has entered into
that certain  Registration  Rights Agreement with the Holders (the "Registration
Rights Agreement"), pursuant to which the Company agreed, among other things, to
register  the  Registrable  Securities  (as defined in the  Registration  Rights
Agreement), including the shares of Common Stock issuable upon conversion of the
Preferred Shares and exercise of the Warrants, under the Securities Act of 1933,
as amended (the "1933 Act"). In connection with the Company's  obligations under
the Registration Rights Agreement,  on ____________ ___, 1999, the Company filed
a  Registration  Statement  on  Form  S-3  (File  No.   333-_____________)  (the
"Registration  Statement")  with the  Securities  and Exchange  Commission  (the
"SEC"),  relating to the Registrable  Securities which names each of the Holders
as a selling stockholder thereunder.

         In connection  with the  foregoing,  we advise you that a member of the
SEC's  staff has  advised  us by  telephone  that the SEC has  entered  an order
declaring the Registration Statement effective under the 1933 Act at [ENTER TIME
OF  EFFECTIVENESS]  on  [ENTER  DATE OF  EFFECTIVENESS],  and to the best of our
knowledge after telephonic  inquiry,  no stop order suspending its effectiveness
has been issued and no  proceedings  for that  purpose are  pending  before,  or
threatened by, the SEC and the  Registrable  Securities are available for resale
under the 1933 Act pursuant to the Registration Statement.

                                       Very truly yours,
                                       [ISSUER'S COUNSEL]
