                                    RECITALS

     A. The Company and Purchaser are executing and delivering this Agreement in
reliance  upon  the  exemption  from  securities  registration  afforded  by the
provisions of Regulation D ("Regulation D"), as promulgated by the United States
Securities and Exchange Commission (the "SEC") under the Securities Act of 1933,
as amended (the "Securities Act").

     B. Purchaser desires (a) to purchase,  upon the terms and conditions stated
in this Agreement,  up to Four Million  ($4,000,000) U.S. Dollars face amount of
the Company's Series D Preferred Stock (the "Preferred Shares"), pursuant to the
Certificate of Designation attached hereto as Exhibit A, convertible into shares
of the Company's  common stock,  par value $0.01 per share (the "Common  Stock")
and (b) to receive, in consideration for such purchase,  Stock Purchase Warrants
(the "Warrants"), in the form attached hereto as Exhibit B, to acquire shares of
Common  Stock.  The  Preferred  Shares  will be  funded  in  closings  (each,  a
"Closing") of two tranches,  with an initial closing of Two Million Five Hundred
Thousand  ($2,500,000)  U.S.  Dollars face amount of the  Preferred  Shares (the
"First Closing"), and a second closing of One Million Five Hundred Thousand U.S.
Dollars face amount of Preferred  Shares (the  "Second  Closing"),  in each case
subject  to the terms and  conditions  stated in this  Agreement.  The shares of
Common Stock to be issued to the  Purchaser  upon  conversion  of the  Preferred
Shares are referred to herein as the "Common Shares." The shares of Common Stock
issuable upon exercise of or otherwise  pursuant to the Warrants are referred to
herein as  "Warrant  Shares."  The  Preferred  Shares,  the Common  Shares,  the
Warrants,  and the  Warrant  Shares are  collectively  referred to herein as the
"Securities."

     C. Contemporaneously with the execution and delivery of this Agreement, the
parties hereto are executing and delivering a Registration  Rights  Agreement in
the form attached  hereto as Exhibit C (the  "Registration  Rights  Agreement"),
pursuant to which the Company has agreed to provide certain  registration rights
under the Securities Act, the rules and regulations  promulgated  thereunder and
applicable state securities laws.

                                   AGREEMENTS

     NOW,  THEREFORE,  in consideration of their respective  promises  contained
herein and other good and valuable consideration, the receipt and sufficiency of

                                   ARTICLE II
                         PURCHASER'S REPRESENTATIONS AND
                                   WARRANTIES

     Purchaser  represents  and  warrants  solely with respect to itself and its
purchase  hereunder to the Company as of the date  hereof,  as set forth in this
Article II. Purchaser makes no other  representations or warranties,  express or
implied, to the Company in connection with the transactions  contemplated hereby
and any and all prior  representations  and  warranties,  if any, which may have
been made by the  Purchaser to the Company in connection  with the  transactions
contemplated  hereby shall be deemed to have been merged in this  Agreement  and
any such prior  representations  and  warranties,  if any, shall not survive the
execution and delivery of this Agreement.

                                       3
<PAGE>

     2.1 Investment  Purpose.  Purchaser is purchasing the Preferred  Shares and
the Warrants for Purchaser's own account for investment only and not with a view
toward  or in  connection  with  the  public  sale or  distribution  thereof  in
violation of the applicable  securities  laws.  Purchaser will not,  directly or
indirectly,  offer,  sell, pledge or otherwise  transfer the Preferred Shares or
Warrants or any interest therein except pursuant to transactions that are exempt
from the registration requirements of the Securities Act and/or sales registered
under the Securities Act, the rules and regulations promulgated pursuant thereto
and applicable state securities laws. Purchaser  understands that Purchaser must
bear the economic risk of this  investment  indefinitely,  unless the Securities
are  registered  pursuant  to  the  Securities  Act  and  any  applicable  state
securities laws or an exemption from such  registration  is available,  and that
the Company has no present  intention of registering any such  Securities  other
than as  contemplated  by the  Registration  Rights  Agreement.  By  making  the
representations  in this Section 2.1, the  Purchaser  does not agree to hold 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 from  registration  under the Securities
Act and any applicable state securities laws.

     2.2 Accredited  Investor Status.  Purchaser is an "accredited  investor" as
that term is defined in Rule 501(a) of  Regulation D and Purchaser has indicated
on a duly executed Investor  Questionnaire and  Representation  Agreement in the
form attached hereto as Exhibit E and delivered to the Company in which capacity
it so qualifies as an "accredited investor."

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

     2.4 Information. Purchaser or its counsel have been furnished 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  specifically
requested by Purchaser,  as well as the Company's Annual Report on Form 10-KSB/A
for the Year ended April 30, 1997;  Quarterly Report on Form 10-Q for the period
ended July 31,  1997;  Quarterly  Report on Form  10-QSB  for the  period  ended
October 31, 1997;  Current Reports on Form 8-K filed with the SEC on October 16,
1997 and October 25, 1997;  and Proxy  Statement  filed with the  Securities and
Exchange  Commission ("SEC") on September 5, 1997 (such documents  collectively,
the  "SEC  Documents").  Purchaser  has been  afforded  the  opportunity  to ask
questions of the Company and has received what Purchaser believes to be complete
and satisfactory  answers to any such inquiries.  Neither such inquiries nor any
other  due  diligence  investigation  conducted  by  Purchaser  or  any  of  its
representatives  nor any  other  disclosures  or  documents  (including  without
limitation the SEC Documents) shall modify, amend or affect Purchaser's right to
rely on the Company's representations and warranties contained in this Agreement
or in any Exhibit hereto or in any certificate issued in connection  herewith or
therewith.  Purchaser understands that Purchaser's  investment in the Securities

                                       4
<PAGE>

involves  a high  degree of risk,  including  without  limitation  the risks and
uncertainties  disclosed in the SEC  Documents  and the  Prospectus  (as defined
below).  Subject  to  the  foregoing,  Purchaser  acknowledges  the  disclosures
presented  under the caption "Risk Factors" in the Company's Form 10-K/A for the
year ended April 30, 1997 and in the Prospectus,  and the incorporation of those
disclosures by reference herein; provided that such Risk Factors shall not limit
the Company's representations and warranties contained herein.


     2.5  Governmental  Review.  Purchaser  understands  that no  United  States
federal  or state  agency or any other  government  or  governmental  agency has
passed upon or made any recommendation or endorsement of the Securities.

     2.6 Transfer or Resale.  Purchaser  understands that (i) except as provided
in the Registration  Rights Agreement,  the Securities have not been and are not
being  registered under the Securities Act or any state securities laws, and may
not be offered,  sold,  pledged or  otherwise  transferred  unless  subsequently
registered thereunder or an exemption from such registration is available (which
exemption the Company  expressly  agrees may be established as  contemplated  in
clauses (b) and (c) of Section  5.1  hereof);  (ii) any sale of such  Securities
made in reliance  on Rule 144 under the  Securities  Act (or a  successor  rule)
("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 such Securities  without
registration  under the Securities Act under  circumstances  in which the seller
may be deemed to be an  underwriter  (as that term is defined in the  Securities
Act) may require  compliance  with some other exemption under the Securities 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  Securities  Act or any state  securities  laws or to comply  with the
terms and  conditions  of any  exemption  thereunder  (in each case,  other than
pursuant to this Agreement or the Registration Rights Agreement).

2.7  Legends.  Purchaser  understands  that,  subject to  Article V hereof,  the
certificates  for the Preferred  Shares and Warrants and, until such time as the
Common Shares and Warrant Shares have been  registered  under the Securities Act
as contemplated by the Registration Rights Agreement or otherwise may be sold by
Purchaser pursuant to Rule 144 (subject to and in accordance with the procedures
specified  in  Article V hereof),  the  certificates  for the Common  Shares and
Warrant Shares,  will bear a restrictive  legend (the "Legend") in substantially
the following form:

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF
         ANY STATE OF THE UNITED STATES.  THE SECURITIES  REPRESENTED HEREBY MAY
         NOT BE OFFERED OR SOLD OR  OTHERWISE  TRANSFERRED  IN THE ABSENCE OF AN
         EFFECTIVE  REGISTRATION  STATEMENT FOR THE SECURITIES  UNDER APPLICABLE
         SECURITIES LAWS OR UNLESS OFFERED,  SOLD OR TRANSFERRED  PURSUANT TO AN
         AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THOSE LAWS.

     After  registration  of the Common  Shares  and  Warrant  Shares,  or sales
pursuant to Rule 144 (subject to and in accordance with the procedures specified
in Article V hereof),  certificates  for such  shares  will be issued  without a
restrictive legend.

                                       5

     2.8 Authorization:  Enforcement. This Agreement and the Registration Rights
Agreement  have been duly and validly  authorized,  executed  and  delivered  on
behalf  of  Purchaser  and  are  valid  and  binding   agreements  of  Purchaser
enforceable in accordance with their respective terms,  except (i) to the extent
that such  validity  or  enforceability  may be  subject to or  affected  by any
bankruptcy, insolvency, reorganization,  moratorium, liquidation or similar laws
relating to, or affecting  generally the  enforcement of,  creditors'  rights or
remedies of creditors  generally,  or by other  equitable  principles of general
application,  and  (ii) as  rights  to  indemnity  and  contribution  under  the
Registration  Rights  Agreement  may be limited  by Federal or state  securities
laws.

     2.9 Residency.  Purchaser is a resident of the jurisdiction set forth under
Purchaser's name on the signature page hereto executed by Purchaser.

                                   ARTICLE III
                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company  represents and warrants to the Purchaser as of the date hereof
and as of each Closing as set forth in this  Article  III. The Company  makes no
other  representations  or warranties,  express or implied,  to the Purchaser in
connection  with the  transactions  contemplated  hereby  and any and all  prior
representations and warranties,  if any, which may have been made by the Company
to the Purchaser in connection with the transactions  contemplated  hereby shall
be  deemed  to  have  been  merged  in  this   Agreement   and  any  such  prior
representations  and  warranties,  if any,  shall not survive the  execution and
delivery of this Agreement; provided, however, that the foregoing does not limit
any  material  misstatement  or  omission  by  any  officer  of the  Company  in
connection  with the  Purchaser's due diligence and does not limit the rights or
remedies  pursuant  thereto or in connection  with any  violations of securities
laws.

     3.1   Organization  and   Qualification.   Each  of  the  Company  and  its
subsidiaries is a corporation duly organized and existing in good standing under
the laws of the jurisdiction in which it is incorporated,  and has the requisite
corporate  power to own its properties and to carry on its business as now being
conducted.  The  Company and each of its  subsidiaries  is duly  qualified  as a
foreign corporation to do business and is in good standing in every jurisdiction
where the  failure so to qualify  or be in good  standing  would have a Material
Adverse Effect.  "Material Adverse Effect" means any effect which,  individually
or in the aggregate with all other effects,  is or could  reasonably be expected
to be materially  adverse to the  business,  operations,  properties,  assets or
liabilities,  financial condition, operating results or prospects of the Company
and  its  subsidiaries,  taken  as a whole  on a  consolidated  basis  or on the
transactions contemplated hereby or on any of the Securities.

     3.5  No  Conflicts.  The  execution,   delivery  and  performance  of  this
Agreement,  the  Preferred  Shares,  the  Warrants and the  Registration  Rights
Agreement by the Company,  and the  consummation  by the Company of transactions
contemplated hereby and thereby (including, without limitation, the issuance and
reservation for issuance, as applicable, of the Preferred Shares, Common Shares,
Warrants,  and Warrant  Shares)  will not (a)  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 result in a violation of
any law,  rule,  regulation,  order,  judgment  or  decree  (including,  without
limitation, U.S. federal and state securities laws and regulations and the rules
and regulations of Nasdaq) applicable to the Company or any of its subsidiaries,

                                       8
<PAGE>

or by which any property or asset of the Company or any of its subsidiaries,  is
bound or affected (except for such possible conflicts,  defaults,  terminations,
amendments,   accelerations,   cancellations   and   violations  as  would  not,
individually  or in the  aggregate,  have a Material  Adverse Effect or that are
related to any  inaccuracies or omissions in any  representation  or warranty of
the Purchaser set forth herein), or (b) result in a violation of the Certificate
of Incorporation or By-laws.  Neither the Company nor any of its subsidiaries is
in   violation  of  its   Certificate   of   Incorporation,   By-laws  or  other
organizational documents, and neither the Company nor any of its subsidiaries is
in default  (and no event has  occurred  which has not been waived  which,  with
notice  or  lapse  of  time  or  both,  would  put  the  Company  or  any of its
subsidiaries in default)  under,  nor has there occurred any event giving others
(with  notice or lapse of time or both) 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,  except  for  possible
violations,  defaults or rights as would not,  individually or in the aggregate,
have  a  Material  Adverse  Effect.  The  businesses  of  the  Company  and  its
subsidiaries  are not being  conducted,  and shall not be  conducted  so long as
Purchaser  (or any direct or indirect  transferee,  assignee or  participant  of
Purchaser or of such transferee, assignee or participant in a transaction of the
type referred to in Section 5.1(b) below ("Purchaser  Transferee"))  owns any of
the Securities,  in violation of any law, ordinance,  rule,  regulation,  order,
judgment or decree of any governmental entity,  court or arbitrator,  except for
possible  violations  the  sanctions  for which  either  individually  or in the
aggregate  would  not have a  Material  Adverse  Effect.  Except as set forth on
Schedule 3.5, or except (A) such as may be required  under the Securities Act in
connection  with  the  performance  of  the  Company's   obligations  under  the
Registration  Rights  Agreement,  (B)  filing of a Form D with the SEC,  and (C)
compliance   with  the  state   securities   or  Blue  Sky  laws  of  applicable
jurisdictions,  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 this  Agreement,  the Preferred
Shares,  the  Warrants or the  Registration  Rights  Agreement or to perform its
obligations in accordance  with the terms hereof or thereof.  The Company is not
in  violation  of the  listing  requirements  of  Nasdaq,  does  not  know of or
anticipate  any event  which could be grounds  for such  delisting  and does not
reasonably  anticipate that the Common Shares will be delisted by Nasdaq for the
foreseeable future.

Securities Exchange Act of 1934, as amended (the "Exchange Act") and has been so

April 30,  1997,  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 Exchange Act and any other material filings
required to be made with the SEC (collectively  the "Filed SEC Documents").  The
Company  has  delivered  to  Purchaser  true  and  complete  copies  of the  SEC
Documents,  except for exhibits,  schedules and  incorporated  documents.  As of
their  respective  dates,  the  Filed SEC  Documents  complied  in all  material
respects with the requirements of the Exchange Act and the rules and regulations
of the SEC  promulgated  thereunder  applicable to the Filed SEC Documents,  and
none of the Filed SEC  Documents,  at the time  they  were  filed  with the SEC,
contained any untrue statement of a material fact or omitted to state a material


                                       9
<PAGE>

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. None of the statements made in any such Filed SEC Documents which is
required to be updated or amended under  applicable  law has not been so updated
or amended.  The financial  statements of the Company  included in the Filed SEC
Documents  have  been  prepared  in  accordance  with  U.S.  generally  accepted
accounting  principles,  consistently  applied, and the rules and regulations of
the SEC 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 do not include footnotes or are condensed
or  summary  statements)  and,  fairly  present  in all  material  respects  the
consolidated financial position of the Company and its consolidated subsidiaries
as of the dates thereof and the  consolidated  results of their  operations  and
cash  flows  for the  periods  then  ended  (subject,  in the case of  unaudited
statements,  to normal,  immaterial year-end audit  adjustments).  Except as set
forth in the financial  statements or the notes thereto of the Company  included
in the SEC Documents,  the Company has no liabilities,  contingent or otherwise,
other  than  (i)  liabilities  incurred  in  the  ordinary  course  of  business
consistent  with  past  practice  subsequent  to  the  date  of  such  financial
statements and (ii) obligations under contracts and commitments  incurred in the
ordinary course of business  consistent with past practice and (iii) liabilities
not required under generally accepted  accounting  principles to be reflected in
such financial statements, in each case of clause (i), (ii) and (iii) next above
which,  individually  or in the  aggregate,  are not  material to the  financial
condition, business, operations,  properties,  operating results or prospects of
the Company and its subsidiaries or to the transactions  contemplated  hereby or
to the  Securities.  To the extent  required by the rules of the SEC  applicable
thereto,  the Filed SEC  Documents  contain a complete and accurate  list of all
material  undischarged  written or oral contracts,  agreements,  leases or other
instruments  and there are no other  material  Contracts  in effect to which the
Company or any  subsidiary is a party or by which the Company or any  subsidiary
is bound or to which  any of the  properties  or assets  of the  Company  or any
subsidiary is subject (each a "Contract")  existing as of the respective date of
each such Filed SEC  Document  (or such other date  required by the rules of the
SEC). Except as set forth in Schedule 3.6, none of the Company, its subsidiaries
or, to the best knowledge of the Company,  any of the other parties thereto,  is
in breach or violation of any Contract,  which breach or violation  would have a
Material Adverse Effect.  No event,  occurrence or condition exists which,  with
the lapse of time, the giving of notice,  or both, would become a default by the
Company or its  subsidiaries  thereunder  which  would  have a Material  Adverse
Effect.  The Company has not  provided  and will not  provide to  Purchaser  any
material  non-public  information or any other information  which,  according to
applicable law, rule or regulation,  should have been disclosed  publicly by the
Company but which has not been so disclosed as of the date of this Agreement and
the date of the applicable Closing.

     3.7 Absence of Certain  Changes.  Since April 30,  1997,  there has been no
material  adverse  change and no material  adverse  development in the business,
properties,  operations, financial condition, results of operations or prospects
of the Company,  except as  disclosed in Schedule 3.7 or clearly  evident in the
SEC Documents.

     3.8 Absence of  Litigation.  Except as  disclosed in Schedule 3.8 or in the
SEC Documents,  there is no action, suit,  proceeding,  inquiry or investigation
before or by any court,  public board,  government  agency,  or  self-regulatory
organization  or body pending or, to the  knowledge of the Company or any of its
subsidiaries,   threatened  against  or  affecting  the  Company,   any  of  its
subsidiaries,  or any  of  their  respective  directors  or  officers  in  their
capacities  as  such,  which  could  reasonably  be  expected  to  result  in an
unfavorable  decision,  ruling or finding  which  would have a Material  Adverse
Effect or would adversely affect the transactions contemplated by this Agreement
or any of the documents  contemplated hereby or which would adversely affect the
validity or  enforceability  of, or the  authority  or ability of the Company to
perform its obligations  under,  this Agreement or any of such other  documents.
There are no facts known to the Company which, if known by a potential  claimant
or governmental authority,  could reasonably be expected to give rise to a claim
or proceeding  which,  if asserted or conducted with results  unfavorable to the
Company or any of its  subsidiaries,  could  reasonably  be  expected  to have a
Material Adverse Effect.

         3.9 Disclosure. No information, statement or representation relating to
or concerning the Company or any of its subsidiaries set forth in this Agreement
or provided to Purchaser in connection with the transactions contemplated hereby
contains an untrue  statement of a material fact. No information  relating to or
concerning  the Company or any of its  subsidiaries  set forth in any of the SEC
Documents  contains a statement of material  fact that was untrue as of the date
such SEC Document was filed with the SEC. The Company has not omitted to state a
material fact necessary in order to make the statements and representations made
herein or therein, in light of the circumstances under which they were made, not
misleading.  Except for the  execution and  performance  of this  Agreement,  no
material fact (within the meaning of the federal  securities  laws of the United
States and of  applicable  state  securities  laws)  exists with  respect to the
Company or any of its subsidiaries which has not been publicly disclosed.

     3.10 Acknowledgment  Regarding Purchaser's Purchase of the Securities.  The
Company  acknowledges  and agrees  that  Purchaser  is not acting as a financial
advisor  or  fiduciary  of the  Company  or any of its  subsidiaries  (or in any
similar   capacity)  with  respect  to  this   Agreement  or  the   transactions
contemplated  hereby,  that  this  Agreement  and the  transaction  contemplated
hereby,  and  the  relationship  between  the  Purchaser  and the  Company,  are
"arms-length",  and  that  any  statement  made  by  Purchaser,  or  any  of its
representatives   or  agents,   in  connection   with  this  Agreement  and  the
transactions  contemplated  hereby is not advice or a recommendation,  is merely
incidental to  Purchaser's  purchase of the  Securities  and has not been relied
upon as advice or  recommendations  in any way by the  Company,  its officers or
directors or other representatives.  The Company further represents to Purchaser
that the Company's  decision to enter into this  Agreement and the  transactions
contemplated  hereby have been based solely on an independent  evaluation by the
Company and its representatives.

     3.12 No General  Solicitation.  Neither  the  Company  nor any  distributor
participating on the Company's behalf in the  transactions  contemplated  hereby
(if any) nor any person  acting for the Company,  or any such  distributor,  has
conducted  any  "general  solicitation,"  as  described  in  Rule  502(c)  under
Regulation D, with respect to any of the Securities being offered hereby.

     3.13  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 either require  registration of
any of the  Securities  under  the  Act  or  prevent  the  parties  hereto  from
consummating,  or delay or interfere with the  consummation of, the transactions
contemplated  hereby  pursuant to an exemption from the  registration  under the
Securities  Act pursuant to the  provisions of  Regulation  D. The  transactions
contemplated  hereby  are  exempt  from  the  registration  requirements  of the
Securities  Act,  assuming  the  accuracy of the  relevant  representations  and
warranties   herein  contained  of  the  Purchaser  and  of  Shoreline   Pacific
Institutional  Finance,  the  Institutional  Division  of  Financial  West Group
("Shoreline")  in their letter to the Company  dated as of April 24 1998 (a copy
of which is attached as Schedule  3.13  hereto) to the extent  relevant for such
determination.  To the Company's knowledge,  such representations and warranties
of Shoreline are accurate.

     3.14 No Brokers.  The Company has taken no action,  directly or indirectly,
which  would  give rise to any claim by any person  for  brokerage  commissions,
finder's fees or similar payments by Purchaser relating to this Agreement or the
transactions contemplated hereby, except for dealings with Shoreline the fees of
which shall be paid in full by the  Company.  The  Company  will  indemnify  the
Purchaser from and against any fees and expenses  (including  without limitation
reasonable  attorneys  fees  and  expenses)  sought  or  other  claims  made  by
Shoreline.

     3.15 Intellectual Property.  Except as disclosed in the SEC Documents, each
of the  Company and its  subsidiaries  owns,  is  licensed to use, or  possesses
adequate  and   enforceable   rights  to  use  all  material   patents,   patent
applications,  trademarks,  trademark applications,  trade names, service marks,
copyrights, copyright applications,  licenses, know-how (including trade secrets
and  other   unpatented   and/or   unpatentable   proprietary  or   confidential
information,  systems or procedures)  and other similar  rights and  proprietary
knowledge (collectively, "Intangibles") used or necessary for the conduct of its
business as now being conducted or as currently contemplated to be conducted and
as described in the  Company's  Annual Report on Form 10-K/A (as modified by any
Form  10-Q or Form 8-K filed  prior to the date  hereof)  for its most  recently
ended fiscal year. To the Company's best  knowledge,  except as disclosed in the
SEC Documents,  neither the Company nor any subsidiary of the Company  infringes
on or is in  conflict  with any right of any other  person  with  respect to any
Intangibles nor is there any claim of infringement made by a third party against
or  involving  the  Company  or  any of its  subsidiaries,  which  infringement,
conflict  or  claim,  individually  or in the  aggregate,  could  reasonably  be
expected to result in an  unfavorable  decision,  ruling or finding  which would
have a Material Adverse Effect.

                                       12

     3.16 Key  Employees.  Each Key  Employee  (as defined  below) is  currently
serving the Company in the capacity disclosed in Schedule 3.16. No Key Employee,
to the best of the knowledge of the Company and its subsidiaries,  is, or is now
expected to be, in violation of any material  term of any  employment  contract,
confidentiality,    disclosure    or    proprietary    information    agreement,
non-competition agreement, or any other contract or agreement or any restrictive
covenant, and the continued employment of each Key Employee does not subject the
Company or any of its  subsidiaries  to any liability with respect to any of the
foregoing  matters.  No Key  Employee  has, to the best of the  knowledge of the
Company and its subsidiaries, any intention to terminate his employment with, or
services  to, the  Company or any of its  subsidiaries  and the  Company  has no
present  intention  to  terminate  the  employment  of any  Key  Employee.  "Key
Employee" means each person identified as such on Schedule 3.16.

     3.17  Shareholder  Rights  Plan.  The  Company  does not  have in  effect a
shareholders rights plan or similar plan in the nature of a "poison pill."

     3.18 Dilution.  The number of Common Shares and Warrant Shares may increase
substantially in certain  circumstances  (subject to the limitations on issuance
of  Common  Shares  in  certain  circumstances  set  forth in  Article  V of the
Certificate of Designation), including the circumstances where the trading price
of the Company's  Common Stock declines.  The Company's  executive  officers and
directors have studied and fully  understand the nature of the securities  being
sold hereunder and recognize  that they have a potential  dilutive  effect.  The
board of  directors  of the Company  has  concluded  in its good faith  business
judgement  that such  issuance  is in the best  interests  of the  Company.  The
Company  acknowledges  that its  obligation  to issue Common  Shares and Warrant
Shares upon  conversion of the Preferred  Shares and exercise of the Warrants is
(subject to the  limitation on issuance of Common Shares set forth in Sections V
of the Certificate of Designation) absolute and unconditional, regardless of the
dilution that such issuance may have on other shareholders of the Company.

     3.19 Certain  Transactions.  Except as disclosed in the SEC  Documents  and
except for arm's length transactions pursuant to which the Company or any of its
direct  or  indirect  subsidiaries  makes  payments  in the  ordinary  course of
business upon terms no less  favorable  than the Company or any of its direct or
indirect  subsidiaries  could obtain from third  parties,  none of the officers,
directors,  or employees of the Company is presently a party to any  transaction
(including,  without  limitation,  any lease or  license  arrangement)  with the
Company or any of its direct or indirect  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.

     3.20 Permits;  Compliance.  The Company and each of its direct and indirect
subsidiaries  is  in  possession  of  all  franchises,  grants,  authorizations,
licenses, permits, easements,  variances,  exemptions,  consents,  certificates,
approvals and orders  necessary to own,  lease and operate its properties and to
carry on its business as it is now being conducted  (collectively,  the "Company
Permits"),  and there is no action  pending or, to the knowledge of the Company,
threatened  regarding  suspension or  cancellation of any of the Company Permits
except  for such  Company  Permits  the  failure  of which  to  possess,  or the
cancellation  or  suspension  of  which,  would  not,  individually  or  in  the
aggregate,  have a Material  Adverse Effect.  Neither the Company nor any of its
direct or indirect  subsidiaries is in conflict with, or in default or violation
of, any of the  Company  Permits,  except for any such  conflicts,  defaults  or
violations  which,  individually  or in the  aggregate,  would not reasonably be
expected to have a Material  Adverse Effect.  Since April 30, 1997,  neither the
Company  nor  any of its  direct  or  indirect  Subsidiaries  has  received  any
notification  with  respect to possible  conflicts,  defaults or  violations  of
applicable laws, except for notices relating to possible conflicts,  defaults or
violations,  which  conflicts,  defaults or violations would not have a Material
Adverse Effect.

     3.21   Insurance.   The  Company  and  each  of  its  direct  and  indirect
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 prudent and customary in the  businesses in which the Company and
its direct and indirect  subsidiaries  are engaged.  Neither the Company nor any
such direct or indirect subsidiary 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 have a Material Adverse Effect.

                                   ARTICLE IV
                                    COVENANTS

     4.1 Best  Efforts.  The  parties  shall use their  best  efforts  to timely
satisfy  each  of the  conditions  described  in  Articles  VI and  VII of  this
Agreement.

     4.2  Securities  Laws.  The  Company  agrees to  timely  file a Form D with
respect to the  Securities  with the SEC as required  under  Regulation D and to
provide  a copy  thereof  to  Purchaser  on or prior to the First  Closing.  The
Company agrees to file a Form 8-K (with this  Agreement and all Exhibits  hereto
attached  thereto)  disclosing this Agreement and the transactions  contemplated
hereby with the SEC within three (3)  business  days  following  the date of the
First Closing. The Company shall, on or prior to the date of each Closing,  take
such action as is necessary to qualify the  Securities for sale to the Purchaser
in compliance with applicable securities laws of the states of the United States
or obtain exemption therefrom,  and shall provide evidence of any such action so
taken to the Purchaser on or prior to the date of each Closing. Without limiting
any of the Company's  obligations under this Agreement,  the Registration Rights

owns any of the  Securities,  (a) the  Company  shall  timely  file all  reports
required to be filed with the SEC pursuant to the Exchange  Act, and the Company

eligibility  to  register  its Common  Shares on Form SB-2,  or,  upon  becoming

     4.6 Right of First  Offer.  From the date hereof until the day which is one
year  following  the date of the First  Closing,  the Company shall not issue or
sell, or agree to issue or sell any equity or debt  securities of the Company or
any of its  subsidiaries  (or any security  convertible  into or  exercisable or
exchangeable,  directly  or  indirectly,  for equity or debt  securities  of the
Company or any of its  subsidiaries)  ("Future  Offerings")  unless the  Company
shall have first  delivered  to Purchaser at least  fifteen (15)  business  days
prior to the closing of such Future  Offering,  written  notice  describing  the
proposed  Future  Offering,  including  the terms and  conditions  thereof,  and

1933) an option  during the ten (10) business day period  following  delivery of
such notice to purchase up to the full amount of the securities being offered in
the Future  Offering on the same terms as  contemplated  by such Future Offering
(the limitations  referred to in this sentence are  collectively  referred to as

apply to any transaction  involving issuances of securities in connection with a

the Company's options,  warrants or other convertible  securities outstanding as
of the date hereof or (b) the grant of  additional  options or warrants,  or the

prohibit  any Common  Stock or other  security  issued  subject  to the  Capital
Raising  Limitations  but not  purchased  by  Purchaser  from  being  converted,
exercised or resold until the day following the first anniversary of the date of
the Closing and shall take all actions necessary (including, without limitation,
the issuance of a stop transfer order) to effect such prohibition.

trading of its  Common  Stock and the Common  Shares and  Warrant  Shares on the
Nasdaq Small Cap Market,  the AMEX, the Nasdaq  National  Market or the New York
Stock  Exchange;  and  comply  in  all  material  respects  with  the  Company's
reporting,  filing and other  obligations  under the  By-laws  and rules of such
Exchange or Nasdaq,  as  applicable.  If and so long as the Common Stock and the
Common  Shares and  Warrant  Shares are not listed on one of such  Exchanges  or
markets, as partial  compensation for the added liquidity risk of such delisting
the Company  shall be obligated to make the following  additional  cash payments
(the "Delisting Payments").  The Delisting Payments will be equal to one percent
(1%) of the  Purchase  Price  (plus  accrued  but not  unpaid  interest)  of any
outstanding Preferred Shares for each month (or part thereof) following the date
the Common Stock is delisted (the "Delisting Date") continuing  through the date
the  Common  Stock is  listed  on one of such  Exchanges  or  markets  (the "New
Listing").  The  Delisting  Payments will be paid to the holder of the Preferred
Shares in cash within five (5) business  days  following  the earlier of (i) the
end of each month  following the Delisting  Date, or (ii) the effective  date of
the New Listing.  Nothing herein shall limit the Preferred  Share holder's right

such Exchange or market.

Securities  Act may  require  delivery  of a  prospectus  relating to the Common
Shares in connection with any sale thereof pursuant to a registration  statement
under the  Securities  Act  covering  the resale by the  Purchaser of the Common
Shares being sold, and the Purchaser shall comply with the applicable prospectus
delivery requirements of the Securities Act in connection with any such sale.

     4.9  Intentional  Acts or Omissions.  The Company  shall not  intentionally
perform any act which if  performed,  or  intentionally  omit to perform any act
which,  if omitted to be performed,  would prevent or excuse the  performance of
this Agreement or any of the  transactions  contemplated  hereby or the benefits
intended to be secured thereby by the Purchaser (including,  without limitation,
pursuant to any  agreements or documents  obtained by the Company as a condition
to any Closing hereunder).  The Company will use commercially reasonable efforts
to enforce to the fullest  extent  possible any proxies  provided in  connection
with the transactions contemplated hereunder.

     4.10 Corporate Existence.  So long as Purchaser or any Purchaser Transferee
beneficially  owns any  Preferred  Shares,  Warrants,  Common  Shares or Warrant
Shares, the Company shall maintain its corporate existence,  except in the event
of a merger,  consolidation or sale of all or substantially all of the Company's
assets,  as long as the surviving or successor  entity in such  transaction  (i)
assumes  the  Company's  obligations  hereunder  and  under the  agreements  and
instruments  (including the Preferred Shares,  Warrants and Registration  Rights
Agreement) entered into in connection herewith (regardless of whether or not the
Company would have had a sufficient  number of shares of Common Stock authorized
and  available  for issuance in order to effect the  conversion of all Preferred
Shares  outstanding as of the date of such  transaction)  and (ii) is a publicly
traded  corporation whose common stock is listed for trading on the Nasdaq Small
Cap Market, the Nasdaq National Market, the New York Stock Exchange or the AMEX.

solicit by proxy the  Stockholder  Approval  (as defined in the  Certificate  of
Designation)  by the  stockholders  of the  Company  and  use  its  commercially
reasonable efforts to obtain the Stockholder Approval not later than one hundred
and twenty (l20) days following the date of the First Closing.

     4.12 Hedging Transactions.  The Company understands that the Purchaser is a
so-called  "hedge" fund and the Company hereby  expressly  agrees that Purchaser
shall not in any way be prohibited or restricted  from any purchases or sales of
any securities or other instruments of, or related to, the Company or any of its
securities,  including, without limitation, puts, call, futures contracts, short
sales and hedging and arbitrage  transactions.  Purchaser acknowledges that such
purchases,  sales and other  transactions  may be subject to various Federal and
state securities laws.  Purchaser  further  acknowledges that it has not, within
the last 60 days, effected any short sales of the Common Stock of the Company.

     4.13  Shareholder  Rights Plans.  The Company will not adopt a shareholders
rights plan in the nature of a "poison  pill" which  would be  triggered  by the
Securities.

                                    ARTICLE V
           LEGEND REMOVAL, TRANSFER, CERTAIN SALES, ADDITIONAL SHARES

     5.1 Removal of Legend.  The Legend  shall be removed and the Company  shall
issue,  or shall cause to be issued,  a  certificate  without such Legend to the
holder  of any  Security  upon  which it is  stamped,  and a  certificate  for a
security shall be originally  issued  without the Legend,  if, (a) the resale of
such Security is registered  under the Securities  Act, (b) such holder provides
the Company with an opinion of counsel,  in form,  substance and scope customary
for opinions of counsel in comparable  transactions and reasonably  satisfactory
to the Company and its counsel (the  reasonable  cost of which shall be borne by
the Company if neither an effective  registration statement under the Securities
Act or Rule 144 is available in connection  with such sale) to the effect that a
public sale or transfer of such Security may be made without  registration under
the Securities Act pursuant to an exemption from such registration  requirements
or (c) such Security can be sold  pursuant to Rule 144, the Holder  provides the
Company  with  reasonable  assurances  that the  Security can be so sold without
restriction,  and a registered broker dealer provides to the Company's  transfer
agent and counsel  copies of (i) a "will sell" letter  satisfying the guidelines
established  by the SEC and its  staff  from  time to time and (ii) a  customary
seller's  representation  letter with respect to such a sale to be made pursuant
to Rule 144 and (iii) a Form 144 in respect of such  Security  executed  by such
holder and filed (or mailed for filing) with the SEC or (d) such Security can be
sold  pursuant  to  Rule  144(k).   Purchaser  agrees  to  sell  all  registered
Securities,  including  those  represented  by a  certificate(s)  from which the
Legend has been removed,  or which were  originally  issued  without the Legend,
pursuant to an effective registration  statement,  in accordance with the manner
of  distribution  described  in such  registration  statement  and to  deliver a
prospectus in connection  with such sale or in compliance with an exemption from
the registration  requirements of the Securities Act. In the event the Legend is
removed from any  Security or any Security is issued  without the Legend and the
Security is to be disposed of other than pursuant to the registration  statement
or pursuant to Rule 144, then prior to, and as a condition to, such  disposition
such  Security  shall be relegended  as provided  herein in connection  with any
disposition if the  subsequent  transfer  thereof would be restricted  under the
Securities  Act.  Also,  in the event the Legend is removed from any Security or
any Security is issued without the Legend and thereafter the  effectiveness of a
registration  statement  covering  the  resale  of  such  Security  is  properly
suspended  or a  supplement  or  amendment  thereto is  required  by  applicable
securities laws, then upon reasonable  advance notice to Purchaser  holding such
Security, the Company may require that the Legend be placed on any such Security
that cannot then be sold pursuant to an effective registration statement or Rule
144 or with  respect to which the  opinion  referred to in clause (b) next above
has not been  rendered,  which Legend shall be removed when such Security may be
sold pursuant to an effective  registration statement or Rule 144 or such holder
provides the opinion with respect thereto described in clause (b) next above.

     5.2 Transfer  Agent  Instructions.  The Company shall instruct its transfer
agent to issue  certificates,  registered  in the name of the  Purchaser  or its
nominee,  for the Common Shares and the Warrant Shares in such amounts specified
from time to time by the Purchaser upon  conversion or exercise of the Preferred
Shares and the Warrants,  respectively.  Such certificates shall bear the Legend
only to the extent provided by Section 5.1 above. The Company  covenants that no
instruction other than such instructions referred to in this Article V, and stop
transfer  instructions with respect solely to sales pursuant to any registration
statement under the Registration  Rights Agreement to give effect to Section 2.6
hereof in the case of the Common Shares and Warrant Shares prior to registration
of the Common Shares and Warrant  Shares under the Securities Act or "black-out"
periods as provided in the  Registrations  Rights Agreement  between the Company
and the Purchaser,  dated of such date herewith, 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.  Nothing in this Section
shall affect in any way the  Purchaser's  obligations and agreement set forth in
Section  5.1  hereof  to  resell  the   Securities   pursuant  to  an  effective
registration statement and to deliver a prospectus as required in Section 5.1 in
connection  with  such  sale  or  in  compliance  with  an  exemption  from  the
registration  requirements of applicable  securities laws.  Without limiting the
foregoing, if (a) the Purchaser provides the Company with an opinion of counsel,
which  opinion of counsel shall be in form,  substance  and scope  customary for
opinions of counsel in comparable  transactions  and reasonably  satisfactory to
the Company and its counsel (the  reasonable cost of which shall be borne by the
Company if neither an effective  registration statement under the Securities Act
nor Rule 144 is available in connection  with such sale), to the effect that the
Securities to be sold or transferred  may be sold or transferred  pursuant to an
exemption  from  registration  or (b) the Purchaser  transfers  Securities to an
affiliate  which is an accredited  investor  (within the meaning of Regulation D
under the Securities  Act) and which delivers to the Company in written form the
same  representations,  warranties and covenants made by Purchaser  hereunder or
pursuant to Rule 144, the Company shall permit the transfer, and, in the case of
the Common Shares and Warrant  Shares,  promptly  instruct its transfer agent to
issue  one or  more  certificates  in such  name  and in  such  denomination  as
specified by the Purchaser.  The Company acknowledges that a breach by it of its
obligations  hereunder will cause irreparable harm to Purchaser 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 Article V will be inadequate and agrees,  in the event of a breach or
threatened  breach by the  Company  of the  provisions  of this  Article V, that
Purchaser 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.

     8.7 Successors and Assigns.  This Agreement shall be binding upon and inure
to the benefit of the  parties and their  successors  and  assigns.  Neither the
Company  nor  the  Purchaser  shall  assign  this  Agreement  or any  rights  or
obligations   hereunder   without  the  prior  written  consent  of  the  other.
Notwithstanding  the  foregoing,  the Purchaser may subject to and in compliance
with  Section  5.2  hereof,  assign all or part of its  rights  and  obligations
hereunder  to any of its  "affiliates,"  as  that  term  is  defined  under  the

an accredited  investor (within the meaning of Regulation D under the Securities
Act) and agrees in writing to be bound by this  Agreement.  This provision shall

of this  Agreement  or to assign the  Purchaser's  rights  hereunder to any such

(the "Transaction Documents"),  the Securities may be pledged, and all rights of
Purchaser under this Agreement or any other agreement or document related to the
transaction contemplated hereby may be assigned,  without further consent of the
Company,  to a bona  fide  pledgee  in  connection  with  Purchaser's  margin or
brokerage accounts.

     8.8 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.

     8.9 Survival.  The  representations  and  warranties of the Company and the
Purchaser  and the  agreements  and covenants set forth herein shall survive the
closing hereunder  notwithstanding any due diligence  investigation conducted by
or on behalf of the  Company or any  Purchaser  as the case may be. The  Company
agrees to indemnify and hold harmless any Purchaser and each of such Purchaser's
respective officers, directors,  employees,  partners, agents and affiliates for
loss or damage or expenses  (including  reasonable  attorneys fees) arising as a
result of or related to (a) any breach or alleged  breach by the  Company of any
of its representations or covenants set forth herein,  including  advancement of
expenses as they are incurred, (b) any cause of action, suit or claim brought or
made  against  Purchaser  and arising out of or  resulting  from the  execution,
delivery,  performance  or  enforcement  of  the  Transaction  Documents  or the
Certificate of  Designations  or any other  certificate,  instrument or document
contemplated hereby or thereby,  (c) 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 (d)  the  status  of  such  Purchaser  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.

     8.10 Public  Filings:  Publicity.  As soon as  practicable  following  each
Closing,   the  Company  shall  issue  a  press  release  with  respect  to  the
transactions  contemplated  hereby. The Company and the Purchaser shall have the
right to approve  before  issuance  any press  releases,  SEC or Nasdaq or other
exchange   filings,   or  any  other  public  statements  with  respect  to  the
transactions  contemplated  hereby  (which  approval  shall not be  unreasonably
withheld or delayed);  provided,  however,  that the Company  shall be entitled,
without the prior approval of the  Purchaser,  to make any press release or SEC,
AMEX,  Nasdaq or other exchange filings with respect to such  transactions as is
required by applicable law and regulations  (although the Company shall make all
reasonable  efforts to consult with the  Purchaser in  connection  with any such
press release  prior to its release and shall provide the Purchaser  with a copy
thereof as provided in Section 4.4 hereof).

     8.11 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.

     8.12  Remedies.  No  provision  of this  Agreement,  the other  Transaction
Documents or any other transactions contemplated herein or therein providing for
any  remedy to  Purchaser  shall  limit any  remedy  which  would  otherwise  be
available to such  Purchaser at law or in equity.  Nothing in this  Agreement or
any other transactions  contemplated herein shall limit any rights Purchaser may
have under any applicable  federal or state  securities laws with respect to the
investment  contemplated hereby. The Company acknowledges that a breach by it of
its obligations hereunder will cause irreparable harm to Purchaser. Accordingly,
the  Company  acknowledges  that the remedy at law for a material  breach of its
obligations  under this Agreement will be inadequate and agrees, in the event of
a  breach  or  threatened  breach  by the  Company  of the  provisions  of  this
Agreement,  that Purchaser shall be entitled, in addition to all other available
remedies,  to an  injunction  restraining  any  breach and  requiring  immediate
compliance,  without the necessity of showing economic loss and without any bond
or other security being required.

                                       26
<PAGE>

     8.13  Termination.  In the  event  that the  First  Closing  shall not have
occurred within forty-eight (48) hours of the execution of the Agreement, unless
the parties agree otherwise, this Agreement shall terminate.

     8.14 Payment Set Aside.  To the extent that the Company  makes a payment or
payments  to  the  Purchaser   hereunder  or  pursuant  to  the  Certificate  of
Designations  or Warrants or the  Purchaser  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 or entity  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.

     8.15  Scope of  Agreement:  Amendments.  Except as  specifically  set forth
herein,  Purchaser makes no  representation,  warranty,  covenant or undertaking
with  respect to the  transactions  contemplated  hereby.  No  provision of this
Agreement  may be waived other than by an  instrument  in writing  signed by the
party to be charged with  enforcement  and no provision of this Agreement may be
amended  other  than by an  instrument  in  writing  signed by the  Company  and
Purchaser.

     IN WITNESS WHEREOF,  the undersigned  Purchaser and the Company have caused
this Agreement to be duly executed as of the date first above written.

                          REGISTRATION RIGHTS AGREEMENT


     THIS  REGISTRATION  RIGHTS  AGREEMENT,  dated as of  April  ,  1998  (the
"Agreement"), is made by and between American Bio Medica Corporation, a New York

                              W I T N E S S E T H :

     WHEREAS,  in connection with the Securities  Purchase Agreement dated April
24,  1998  between  the  Initial   Investor  and  the  Company  (the   "Purchase
Agreement"),  the  Company  has  agreed,  upon  the  terms  and  subject  to the
conditions of said Purchase Agreement, to issue and sell to the Initial Investor
Four Million  ($4,000,000)  U.S.  Dollars face amount of the Company's  Series D
Preferred  Stock  (the  "Preferred  Shares"),  convertible  into  shares  of the
Company's common stock, par value $0.01 per share (the "Common Stock"), together
with Stock Purchase  Warrants (the "Warrants") to purchase  additional shares of
Common Stock. The shares of Common Stock of the Company into which the Preferred
Shares are convertible  and the Warrants are  exercisable  for are  collectively

Preferred  Shares to the Initial  Investor,  the  Company has offered  Preferred
Shares  to other  investors  as part of the same  offering  of  securities  (the
"Offering"),  and each of the other  investors will be entitled to  registration
rights as set forth in this Agreement.

     WHEREAS, to induce the Initial Investor to execute and deliver the Purchase
Agreement,  the Company has agreed to provide certain  registration rights under
the  Securities  Act  of  1933,  as  amended,  and  the  rules  and  regulations
thereunder, or any similar successor statute (collectively, the "1933 Act"), and
applicable state securities laws with respect to the Common Shares;

     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  Initial
Investor hereby agree as follows:

     1.  Definitions.  Capitalized  terms used herein and not otherwise  defined
herein shall have the respective  meanings set forth in the Purchase  Agreement.
As used in  this  Agreement,  the  following  terms  shall  have  the  following
meanings:

with  the  Company,   are  entitled  to  include  their  securities  in  certain
Registration Statements filed by the Company.

     (b) "Investors" means the Initial Investor and any transferees or assignees
of the Initial  Investor  who agree to become  bound by the  provisions  of this
Agreement in accordance with Section 9 hereof.



                                       1
<PAGE>

     (c) "Registrable  Securities" means the Common Shares (including any Common
Shares  issuable  with  respect  to  conversion   default   payments  under  the
Certificate  of  Designation)  issued or issuable  with respect to the Preferred
Stock and the Warrants  (without  regard to any  limitations  on  conversion  or
exercise) and any shares of capital stock issued or issuable,  from time to time
(with any  adjustments),  on or in exchange for or otherwise with respect to the
Common Stock or any other Registrable Securities.

     (d)  "Registration  Period"  means  the  period  between  the  date of this
Agreement  and the  earlier  of (i) the  date on  which  all of the  Registrable
Securities have been sold and no further Registrable Securities may be issued in
the future,  or (ii) the date on which all the  Registrable  Securities  (in the
opinion of Investors' counsel) may be immediately sold without  registration and
without  restriction  as to the  number  of  Registrable  Securities  to be sold
pursuant to Rule 144 or otherwise.

     (e) "Registration  Statement" means a registration statement filed with the
Securities and Exchange Commission (the "SEC") under the 1933 Act.

     (f) The  terms  "register,"  "registered,"  and  "registration"  refer to a
registration  effected  by  preparing  and filing a  Registration  Statement  or
Statements  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
basis ("Rule 415") and  applicable  rules and  regulations  thereunder,  and the
declaration or ordering of effectiveness of such  Registration  Statement by the
SEC.

     2. Registration.

     (a) Mandatory Registration.  The Company will file a Registration Statement
on Form SB-2 or Form S-3 (or if Form SB-2 or Form S-3 is not then available,  on
such  form  of  Registration   Statement  as  is  then  available  to  effect  a
registration only of all Registrable Securities,  and no other securities (other
than  shares of Common  Stock  issuable  upon  exercise  of  warrants  issued to
Shoreline (as defined below) in connection  with the  transactions  contemplated
hereby and under the Securities Purchase  Agreement),  subject to the consent of
the  Investors  and  determined  pursuant  to Section  12  hereof)  with the SEC
registering  the  Registrable  Securities for resale within twenty (20) business
days of the  closing of the  purchase  of the  Preferred  Shares  (the  "Closing
Date").  Upon  becoming  eligible to use Form S-3,  the Company  shall  promptly
convert its Registration  Statement to Form S-3, unless instructed  otherwise by
the  Investors.  To the extent  allowable  under the 1933 Act, the  Registration
Statement  shall  include  the Common  Shares and such  indeterminate  number of
additional  shares of Common Stock as may become issuable upon conversion of the
Preferred Shares and exercise of the Warrants (i) to prevent dilution  resulting
from stock splits, stock dividends or similar transactions, or (ii) by reason of
changes in the conversion price of the Preferred Shares or the exercise price of
the  Warrants  in  accordance  with the terms  thereof.  The number of shares of
Common Stock initially included in such Registration  Statement shall be no less
than two (2) times the number of Common Shares that are issuable upon conversion
of the Preferred Shares and exercise of the Warrants.  The Company shall use its
best efforts to cause such  Registration  Statement to be declared  effective by
the SEC as soon as  practicable  after filing and in any event no later than the
ninetieth (90th) day following the Closing Date (the "Required Effective Date").
Such best efforts shall include,  but not be limited to, promptly  responding to


                                       2
<PAGE>

all  comments  received  from the staff of the SEC.  Should the Company  receive
notification from the SEC that the Registration Statement will receive no action
or no review from the SEC, the Company shall cause such  Registration  Statement
to become effective within five (5) business days of such SEC notification. Once
declared  effective  by the SEC,  the  Company  shall  cause  such  Registration
Statement to remain effective throughout the Registration Period. If at any time
after  effectiveness  of  the  Registration   Statement  sales  cannot  be  made
thereunder  for any reason for a period of more than twenty (20) days during any
twelve (12) month period,  the Company will thereafter make cash payments to the
Investor  as  partial  compensation  for such  delay in an  amount  equal to two
percent (2%) of the purchase price paid for the unconverted Preferred Shares for
the first  month that  sales  cannot be made  under the  effective  Registration
Statement,  and  three  percent  (3%) of said  purchase  price  for  each  month
thereafter,  continuing  through  the date  that  sales  can be made  under  the
effective  Registration  Statement.  Such  payments  will be prorated on a daily
basis for  partial  months and will be paid to the  Investor in cash within five
(5) business days following the end of each month following the twentieth (20th)
day that sales could not be made.

     (c) Late  Registration  Payments.  If the Registration  Statement  required
pursuant to Section 2(a) above has not been  declared  effective by the Required
Effective  Date,  the Company will make cash payments to the Investor as partial
compensation  for  such  delay  (the  "Late  Registration  Payments").  The Late
Registration  Payments  will be equal to one percent (1%) of the purchase  price
paid for the  Preferred  Shares  for the  first  month  following  the  Required
Effective Date, two percent (2%) of the said purchase price for the second month
following the Required  Effective  Date, and three percent (3%) of said purchase
price for each month  thereafter,  continuing  through the date the Registration
Statement is declared effective by the SEC. The Late Registration  Payments will
be prorated on a daily basis for partial  months and will be paid to the Initial
Investor in cash within five (5) business days following the earlier of: (i) the
end of each month  following the Required  Effective Date, or (ii) the effective
date of the  Registration  Statement.  Nothing herein shall limit the Investor's
right to pursue actual damages for the Company's  failure to file a Registration
Statement  or to have  it  declared  effective  by the  SEC on or  prior  to the
Required Effective Date in accordance with the terms of this Agreement.

     (d) Piggyback Registrations. If, at any time prior to the expiration of the
Registration  Period,  the Company decides to register any of its securities for
its own account or for the account of others  (excluding  registrations  for the
Company on Form S-4 or S-8 or their equivalents relating to equity securities to
be issued solely in connection  with an acquisition of any entity or business or
equity  securities  isssuable in connection  with stock option or other employee
benefit  plans),  the Company will promptly give the  Investors  written  notice
thereof,  and will use its best efforts to include in such  registration  all or
any part of the Registrable Securities so requested by such Investors (excluding
any Registrable  Securities  previously  included in a Registration  Statement).
Each Investor's request for registration must be given to the Company in writing
within  fifteen (15) days after  receipt of the notice from the Company.  If the
registration  for which the Company gives notice is a public offering  involving
an  underwriting,  the  Company  will so  advise  the  Investors  as part of the

                                       3
<PAGE>

above-described written notice. In such event, if the managing underwriter(s) of
the public  offering impose a limitation on the number of shares of Common Stock
which  may  be  included  in  the  Registration   Statement  because,   in  such
underwriter(s)'  judgment,  such  limitation  would be  necessary  to  effect an
orderly public distribution,  then the Company will be obligated to include only
such limited  portion,  if any, of the  Registrable  Securities  with respect to
which such  Investors  have  requested  inclusion  hereunder.  Any  exclusion of
Registrable Securities shall be made pro-rata among all Holders of the Company's
securities seeking to include shares of Common Stock in proportion to the number
of shares of Common  Stock  sought to be  included  by such  Holders;  provided,
however, that the Company will not exclude any Registrable Securities unless the
Company has first excluded all  outstanding  securities the Holders of which are
not entitled by right to inclusion of securities in such Registration  Statement
or are not entitled pro rata inclusion with the Registrable Securities. No right
to  registration  of  Registrable  Securities  under this  Section 2(d) shall be
construed  to limit in any way the  registration  required  under  Section  2(a)
above.  The  obligations of the Company under this Section 2(d) will expire upon
the  earlier  of: (i) the  effectiveness  of the  Registration  Statement  filed
pursuant  to  Section  2(a)  above;  (ii) after the  Company  has  afforded  the
opportunity for the Investors to exercise registration rights under this Section
2(d) for two registrations;  provided, however, that any Investor who shall have
had any  Registrable  Securities  excluded  from any  Registration  Statement in
accordance with this Section 2(d) shall be entitled to include in any additional
Registration  Statement  filed by the  Company  the  Registrable  Securities  so
excluded;  or (iii) when all of the Registrable  Securities held by any Investor
may be sold by such  Investor  under Rule 144 under the 1933 Act  without  being
subject to any volume restrictions.

     (e) Eligibility  for Form S-3. The Company  represents and warrants that it
meets the  requirements for the use of Form SB-2 for registration of the sale by
the Investors of the Registrable Securities.  The Company shall file all reports
required  to be filed by the  Company  with the SEC in a timely  manner so as to
become  eligible for the use of Form S-3,  and agrees to become  eligible to use
Form S-3 on or prior to July 31, 1998.

     3.  Additional   Obligations  of  the  Company.   In  connection  with  the
registration of the Registrable Securities, the Company shall have the following
additional obligations:

     (a) The Company shall keep the Registration Statement effective pursuant to
Rule 415 under  the 1933 Act at all  times  during  the  Registration  Period as
defined in Section 1(d) above.

                                       4
<PAGE>

     (b) The  Registration  Statement  (including  any amendments or supplements
thereto and  prospectuses  contained  therein)  filed by the  Company  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 Company
shall prepare and file with the SEC such  amendments  (including  post-effective
amendments)  and  supplements to the  Registration  Statement and the prospectus
used in connection with the Registration Statement as may be necessary to permit
sales  pursuant  to  the   Registration   Statement  at  all  times  during  the
Registration  Period, and, during such period,  shall comply with the provisions
of the 1933 Act with respect to the disposition of all Registrable Securities of
the Company covered by the  Registration  Statement until the termination of the
Registration  Period,  or if  earlier,  such  time  as all of  such  Registrable
Securities  have been  disposed of in  accordance  with the intended  methods of
disposition  by the seller or sellers  thereof as set forth in the  Registration
Statement.  In the event the  number of shares  available  under a  Registration
Statement  filed  pursuant to this  Agreement is, for any three (3)  consecutive
trading  days (the last of such three (3) trading  days being the  "Registration
Trigger  Date"),  insufficient  to cover one hundred fifty percent (150%) of the
Registrable Securities issued or issuable upon conversion of the Preferred Stock
held by any Investor, the Company shall amend, if permissible,  the Registration
Statement,  or file a new  Registration  Statement (on the short form  available
therefor, if applicable),  or both, so as to cover two hundred percent (200%) of
the Registrable Securities issued or issuable to such Investor, in each case, as
soon as  practicable,  but in any event  within  five (5) days in the case of an
amendment and ten (10) days in the case of a  Registration  Statement  after the
Registration  Trigger  Date (based on the market  price of the Common  Stock and
other  relevant  factors on which the Company  reasonably  elects to rely).  The
Company shall cause such amendment and/or new  Registration  Statement to become
effective as soon as practicable following the filing thereof.

     (c) The Company shall furnish to each Investor whose Registrable Securities
are included in the  Registration  Statement  and its legal counsel (i) promptly
after the same is  prepared  and  publicly  distributed,  filed  with the SEC or
received  by the  Company,  one  copy  of the  Registration  Statement  and  any
amendment  thereto;  each  preliminary  prospectus and final prospectus and each
amendment or supplement thereto; and, in the case of the Registration  Statement
required  under Section 2(a) above,  each letter  written by or on behalf of the
Company to the SEC and each item of correspondence  from the SEC or the staff of
the SEC, in each case relating to such  Registration  Statement  (other than any
portion of any item thereof which contains information for which the Company has
sought confidential treatment);  and (ii) such number of copies of a prospectus,
including a preliminary prospectus,  and all amendments and supplements thereto,
and such other  documents as such  Investor may  reasonably  request in order to
facilitate the disposition of the Registrable Securities owned by such Investor.

                                       5
<PAGE>

     (d) The Company  shall use its best efforts to (i) register and qualify the
Registrable  Securities  covered by the Registration  Statement under such other
securities or blue sky laws of such jurisdictions as each Investor who holds (or
has the right to hold) Registrable  Securities being offered reasonably request,
(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.
Notwithstanding  the foregoing  provision,  the Company shall not be required in
connection  therewith or as a condition thereto to (i) qualify to do business in
any  jurisdiction  where it would not  otherwise  be required to qualify but for
this  Section  3(d),  (ii)  subject  itself  to  general  taxation  in any  such
jurisdiction,  (iii)  file a general  consent  to service of process in any such
jurisdiction,  (iv)  provide any  undertakings  that cause  material  expense or
burden to the Company, or (v) make any change in its charter or bylaws, which in
each case the Board of Directors of the Company determines to be contrary to the
best interests of the Company and its stockholders.

     (e) In  the  event  Investors  who  hold  a  majority  in  interest  of the
Registrable  Securities being offered in an offering  pursuant to a Registration
Statement or any  amendment or  supplement  thereto  under  Section 2(a) or 3(b)
select underwriters for such offering,  the Company shall enter into and perform
its  obligations  under an  underwriting  agreement in usual and customary  form
including,  without  limitation,   customary  indemnification  and  contribution
obligations,  with the managing underwriter of such offering.  The Company shall
be  responsible  for payment of the fees of such  underwriters  and the attorney
fees and costs incurred by one attorney  selected by such Investors to represent
their interests in the underwritten offering.

     (f) The  Company  shall  notify (by  telephone  and also by  facsimile  and
reputable  overnight  courier)  each Investor who holds  Registrable  Securities
being sold pursuant to a Registration Statement of the happening of any event of
which the Company has knowledge as a result of which the prospectus  included in
the  Registration  Statement as then in effect includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements  therein,  in light of the circumstances  under
which they were made, not misleading (a "Suspension  Event").  The Company shall
make such  notification  as promptly as  practicable  after the Company  becomes
aware of such Suspension Event,  shall promptly use its best efforts (but in any
event  within  five (5)  days) to  prepare  a  supplement  or  amendment  to the
Registration  Statement to correct such untrue statement or omission,  and shall
deliver a number of copies of such  supplement  or amendment to each Investor as
such Investor may reasonably request.  Notwithstanding anything contained herein
or in the  Securities  Purchase  Agreement,  in the  event  that  the use of the
Registration  Statement is suspended by the Company,  the Company shall promptly
notify all Investors whose securities are covered by the Registration  Statement
of such suspension,  and shall promptly notify each such Investor as soon as the
use of the Registration  Statement may be resumed.  Notwithstanding  anything to
the contrary,  the Company shall cause the Transfer Agent to deliver  unlegended
shares of Common Stock to a  transferee  of an Investor in  accordance  with the
terms  of the  Certificate  of  Designation  in  connection  with  any  sale  of
Registrable  Securities  with respect to which such  Investor has entered into a
contract  for sale prior to receipt of notice of such  suspension  and for which
such Investor has not yet settled.

                                       6
<PAGE>

     (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 and,
if such an order is issued,  shall use its best efforts to obtain the withdrawal
of such order at the  earliest  possible  time and to notify each  Investor  who
holds  Registrable  Securities  being sold (or, in the event of an  underwritten
offering,  the  managing  underwriters)  of the  issuance  of such order and the
resolution thereof.

     (h) The Company  shall  permit a single firm of counsel  designated  by the
Investors who hold a majority in interest of the  Registrable  Securities  being
sold pursuant to such registration to review the Registration  Statement and all
amendments and supplements  thereto (as well as all requests for acceleration or
effectiveness  thereof) a  reasonable  period of time prior to their filing with
the SEC,  and  shall  not  file any  document  in a form to which  such  counsel
reasonably objects.

     (i) The Company shall make generally  available to its security  Holders as
soon as  practical,  but not later than  ninety (90) days after the close of the
period  covered  thereby,  an earnings  statement (in a 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.

     (j) At the request of the  Investors who hold a majority in interest of the
Registrable  Securities  being sold pursuant to such  registration,  the Company
shall  furnish  on the date that  Registrable  Securities  are  delivered  to an
underwriter for sale in connection with the Registration Statement (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, addressed to the
underwriters;  and (ii) an opinion,  dated such date, from counsel  representing
the Company for purposes of such Registration  Statement,  in form and substance
as is customarily  given in an underwritten  public  offering,  addressed to the
underwriters and Investors.

     (k) The Company shall make  available for  inspection by any Investor whose
Registrable  Securities  are  being  sold  pursuant  to such  registration,  any
underwriter  participating  in any  disposition  pursuant  to  the  Registration
Statement,  and any  attorney,  accountant  or other agent  retained by any such
Investor  or  underwriter  (collectively,   the  "Inspectors"),   all  pertinent
financial and other records, pertinent corporate documents and properties of the
Company (collectively,  the "Records"),  as shall be reasonably deemed necessary
by each  Inspector  to enable  each  Inspector  to  exercise  its due  diligence
responsibility,  and cause the  Company's  officers,  directors and employees to
supply all information  which any Inspector may reasonably  request for purposes
of such due diligence;  provided,  however,  that each  Inspector  shall hold in
confidence  and shall not make any  disclosure  (except to an  Investor)  of any
Record or other  information  which the Company  determines  in good faith to be
confidential,  and of which determination the Inspectors are so notified, unless
(i)  the  disclosure  of such  Records  is  necessary  to  avoid  or  correct  a
misstatement or omission in any Registration Statement, (ii) the release of such
Records  is  ordered  pursuant  to a  subpoena  or other  order  from a court or
government  body of competent  jurisdiction,  or (iii) 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  (to the  knowledge of the relevant


                                       7
<PAGE>

Investor).  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  (in form and  substance
satisfactory   to  the  Company)   with  the  Company   with  respect   thereto,
substantially  in the form of this Section 3(k).  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 notice to the Company and allow the Company, at the Company's expense, to
undertake appropriate action to prevent disclosure of, or to obtain a protective
order for, the Records  deemed  confidential.  Nothing herein shall be deemed to
limit the Investor's ability to sell Registrable Securities in a manner which is
otherwise consistent with applicable laws and regulations.

     (l) The Company shall hold in confidence  and shall not make any disclosure
of information  concerning an Investor  provided to the Company  pursuant hereto
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 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 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 notice to such Investor prior
to making such disclosure and allow such Investor,  at its expense, to undertake
appropriate  action to prevent  disclosure  of, or to obtain a protective  order
for, such information.

     (m) The Company shall cause the listing and the  continuation of listing of
all the  Registrable  Securities  covered by the  Registration  Statement on the
Nasdaq National Market System,  the Nasdaq SmallCap  Market,  the New York Stock
Exchange or the American Stock Exchange, and cause the Registrable Securities to
be quoted or listed on each additional national securities exchange or quotation
system upon which the Common Stock is then listed or quoted.

     (n) The Company shall provide a transfer agent and registrar,  which may be
a single  entity,  for the  Registrable  Securities not later than the effective
date of the Registration Statement.

     (o) The Company shall  cooperate  with the  Investors who hold  Registrable
Securities being sold and the managing  underwriter or underwriters,  if any, to
facilitate the timely  preparation and delivery of certificates (not bearing any
restrictive legends) representing  Registrable Securities to be offered pursuant
to the  Registration  Statement  and  enable  such  certificates  to be in  such
denominations or amounts as the case may be, and registered in such names as the
managing  underwriter or  underwriters,  if any, or the Investors may reasonably
request;  and, within one (1) business day after a Registration  Statement which
includes  Registrable  Securities  is ordered  effective by the SEC, the Company
shall deliver, and shall cause legal counsel selected by the Company to deliver,
to the  transfer  agent  for the  Registrable  Securities  (with  copies  to the
Investors  whose  Registrable  Securities  are  included  in  such  Registration
Statement)  instructions  to the transfer agent to issue new stock  certificates
without a legend and an opinion of such counsel that the Common Shares have been
registered.

                                       8
<PAGE>

     (p) At the request of any Investor,  the Company shall promptly 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 the Registration  Statement as may be necessary in order to change the plan
of distribution set forth in such Registration Statement.

     (q) The  Company  shall  comply  with  all  applicable  laws  related  to a
Registration  Statement and offering and sale of securities  and all  applicable
rules and  regulations  of  governmental  authorities  in  connection  therewith
(including,  without limitation,  the Securities Act and the Securities Exchange
Act of 1934, as amended, and the rules and regulations promulgated by the SEC).

     (r) the Company shall take all other reasonable  actions as any Investor or
the  underwriters,  if any, may  reasonably  request to expedite and  facilitate
disposition  by the  Investor  of the  Registrable  Securities  pursuant  to the
Registration Statement.

     4. Obligations of the Investors. In connection with the registration of the
Registrable Securities, the Investors shall have the following obligations:

     (a) 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 each 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 the Registrable
Securities.  At least twenty (20) business  days prior to the first  anticipated
filing  date of the  Registration  Statement,  the  Company  shall  notify  each
Investor of the  information  the Company  requires from each such Investor (the
"Requested  Information") if such Investor elects to have any of such Investor's
Registrable Securities included in the Registration  Statement.  If within three
(3)  business  days prior to the filing date the Company  has not  received  the
Requested Information from an Investor (a "Non-Responsive  Investor"),  then the
Company  may file  the  Registration  Statement  without  including  Registrable
Securities of such Non-Responsive Investor.

     (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 the  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 the Registration Statement.

     (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(f) or 3(g),
such Investor will immediately discontinue disposition of Registrable Securities
pursuant to the  Registration  Statement  covering such  Registrable  Securities
until  such  Investor's  receipt of the  copies of the  supplemented  or amended
prospectus  contemplated  by Section  3(f) or 3(g) and,  if so  directed  by the
Company,  such  Investor  shall  deliver to the  Company  (at the expense of the
Company) or destroy (and deliver to the Company a  certificate  of  destruction)
all copies in such  Investor's  possession  (other than a limited number of file
copies), of the prospectus  covering such Registrable  Securities current at the
time of receipt of such notice.

                                       9
<PAGE>

     (d) Without  limiting any  Investor's  rights under  Sections  2(a) or 3(b)
hereof, no Investor may participate in any underwritten  distribution  hereunder
unless such Investor (i) agrees to sell such Investor's  Registrable  Securities
on the basis provided in any underwriting arrangements approved by the Investors
entitled hereunder to approve such arrangements, (ii) completes and executes all
questionnaires,  powers of attorney,  indemnities,  underwriting  agreements and
other  documents  reasonably  required  under  the  terms  of such  underwriting
arrangements,  and (iii)  agrees to pay its pro rata  share of all  underwriting
discounts and commissions and other fees and expenses of investment  bankers and
any  manager  or  managers  of  such  underwriting  and  legal  expenses  of the
underwriter applicable with respect to its Registrable Securities,  in each case
to the  extent  not  payable  by the  Company  pursuant  to the  terms  of  this
Agreement.

     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, the fees and  disbursements of counsel for
the Company,  and the reasonable fees and  disbursements of one counsel selected
by the Initial Investor  pursuant to Section 3(e) hereof,  shall be borne by the
Company.

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

     (a) To the extent  permitted by law, the Company  will  indemnify  and hold
harmless each Investor who holds such Registrable Securities,  the directors, if
any, of such Investor,  the officers, if any, of such Investor,  each person, if
any,  who  controls  any  Investor  within  the  meaning  of the 1933 Act or the
Exchange Act, any  underwriter  (as defined in the 1933 Act) for the  Investors,
the directors,  if any, of such  underwriter  and the officers,  if any, of such
underwriter,  and each person, if any, who controls any such underwriter  within
the meaning of the 1933 Act or the Exchange Act (each, an "Indemnified Person"),
against any losses, claims, damages,  expenses or liabilities (joint or several)
(collectively together with actions,  proceedings or inquiries by any regulatory
or  self-regulatory  organization,  whether  commenced or  threatened in respect
thereof,  "Claims") to which any of them become  subject under the 1933 Act, the
Exchange Act or otherwise, insofar as such Claims arise out of or are based upon
any of the following  statements,  omissions or  violations in the  Registration
Statement,  or any post-effective  amendment thereof, or any prospectus included
therein: (i) any untrue statement or alleged untrue statement of a material fact
contained in the Registration Statement or any post-effective  amendment thereof
or the omission or alleged omission to state therein a material fact required to
be stated  therein or necessary to make the statements  therein not  misleading,
(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
Exchange Act or any other law, including without limitation any state securities
law or any rule or regulation  thereunder (the matters in the foregoing  clauses


                                       10
<PAGE>

(i)  through   (iii)  being,   collectively,   "Violations").   Subject  to  the
restrictions  set forth in  Section  6(c) with  respect  to the  number of legal
counsel,  the Company shall reimburse the Investors and each such underwriter or
controlling  person and each such other  Indemnified  Person,  promptly  as such
expenses  are  incurred  and are due and  payable,  for any legal  fees 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): (A) shall
not apply to a Claim  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 any  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(c) hereof; (B) with respect to any preliminary  prospectus
shall not inure to the  benefit  of any  Indemnified  Party from whom the person
asserting  any such Claim  purchased  the  Registrable  Securities  that are the
subject thereof (or to the benefit of any person controlling such person) if the
untrue  statement  or omission of material  fact  contained  in the  preliminary
prospectus was corrected on a timely basis in the prospectus, as then amended or
supplemented,  if such  prospectus  was timely  made  available  by the  Company
pursuant to Section 3(c) hereof;  and the Indemnified Party was promptly advised
in writing not to use the incorrect prospectus prior to the use giving rise to a
Violation and such Indemnified Party,  notwithstanding  such notice, used it (C)
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
Persons 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 indemnify and hold harmless, to the
same extent and in the same manner set forth in Section 6(a), the Company,  each
of its  directors,  each of its officers who signs the  Registration  Statement,
each person, if any, who controls the Company within the meaning of the 1933 Act
or the Exchange Act, and any other stockholder  selling  securities  pursuant to
the Registration Statement or any of its directors or officers or any person who
controls such stockholder within the meaning of the 1933 Act or the Exchange Act
(collectively and together with an Indemnified Person, an "Indemnified  Party"),
against any Claim to which any of them may become  subject,  under the 1933 Act,
the Exchange Act or  otherwise,  insofar as such Claim arises out of or is based
upon any  Violation,  in each case 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 promptly  reimburse any legal or other expenses  (promptly as such
expenses  are  incurred  and due and  payable)  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) 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 Agreement (including this Section 6(b) and Section 7) for only
that amount of a Claim as does not exceed the net proceeds  actually received by
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  preliminary  prospectus  shall not inure to the  benefit of any
Indemnified Party if the untrue statement or omission of material fact contained
in the preliminary prospectus was corrected on a timely basis in the prospectus,
as then amended or  supplemented,  and the  Indemnified  Party failed to utilize
such corrected prospectus.

     (c) Promptly  after receipt by an Indemnified  Person or Indemnified  Party
under this Section 6 of notice of the commencement of any action  (including any
governmental  action),  such Indemnified Person or Indemnified Party shall, if a
Claim in respect  thereof is to made against any  indemnifying  party under this
Section  6,  deliver  to  the  indemnifying   party  a  written  notice  of  the
commencement  thereof  and this  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  parties
and the  Indemnified  Person  or the  Indemnified  Party,  as the  case  may be;
provided,  however,  that such Indemnified  Party shall  diligently  pursue such
defense  and that such  Indemnified  Party  shall not be entitled to assume such
defense and an Indemnified  Person or Indemnified  Party shall have the right to
retain  its  own  counsel,  with  the  fees  and  expenses  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  conflicts of interest  between such  Indemnified  Person or
Indemnified  Party and any  other  party  represented  by such  counsel  in such
proceeding  or the actual or  potential  defendants  in, or targets of, any such
action  including both the Indemnified  Person or the Indemnified  Party and any
such Indemnified  Person or Indemnified  Party reasonably  determines that there
may be legal defenses  available to such Indemnified Person or Indemnified Party
which are different from or in addition to those available to such  indemnifying
party.  The  Company  shall  pay for only one  separate  legal  counsel  for the
Investors;  such legal  counsel  shall be  selected by the  Investors  holding a
majority  in  interest  of the  Registrable  Securities.  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. 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 such expense, loss, damage or liability is incurred
and is due and payable.

     7. Contribution.  To the extent any indemnification  provided for herein 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 contribution shall be made under  circumstances where the maker would not
have been  liable for  indemnification  under the fault  standards  set forth in
Section  6, (ii) 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 such fraudulent  misrepresentation,  and (iii) contribution  (together
with any  indemnification  or other  obligations  under this  Agreement)  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 Exchange  Act. With a view to making  available to the
Investors the benefits of Rule 144 promulgated under the 1933 Act or any similar
rule or  regulation of the SEC that may at any time permit the Investors to sell
securities of the Company to the public without  registration  ("Rule 144"), the
Company agrees to:

                                       12
<PAGE>

     (a) File with the SEC in a timely  manner and make and keep  available  all
reports and other  documents  required of the Company under the 1933 Act and the
Exchange 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  4.3  of  the  Securities   Purchase   Agreement)  and  the  filing  and
availability  of such reports and other documents is required for the applicable
provisions of Rule 144; and

     (b)  Furnish to each  Investor  so long as such  Investor  holds  Preferred
Stock, Warrants or 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  Exchange  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  of  the  Investors
hereunder,  including  the  right  to  have  the  Company  register  Registrable
Securities  pursuant to this Agreement  shall be  automatically  assigned by the
Investors to transferees  or assignees of all or any portion of such  securities
only 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 the name and address of such  transferee or assignee and the securities  with
respect to which such  registration  rights are being  transferred  or assigned,
(iii)  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
received 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,  (v) such  transfer  shall have been made in
accordance with the applicable requirements of the Purchase Agreement,  and (vi)
such  transferee  shall be an  "accredited  investor" as that term is defined in
Rule 501 of Regulation D promulgated under the 1933 Act.

     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 hold a majority interest of the
Registrable  Securities  (but not an Investor  who no longer owns any  Preferred
Stock or  Registrable  Securities  and who is not affected by such  amendment or
waiver).  Any amendment or waiver  effected in  accordance  with this Section 10
shall be  binding  upon  each  Investor  and the  Company.  Notwithstanding  the
foregoing,  no  amendment  or waiver  shall  retroactively  affect any  Investor
without its comment or prospectively adversely affect any Investor who no longer
owns any  Preferred  Stock,  Warrants  or  Registrable  Securities  without  its
consent.  Neither  Article 6 nor  Article 7 hereof may be amended or waived in a
manner adverse to an Investor without its consent.

     11.  Third  Party  Beneficiary.  The  parties  acknowledge  and agree  that
Shoreline Pacific Institutional Finance, the Institutional Division of Financial
West  Group  ("Shoreline"),  shall be deemed a third  party  beneficiary  of the
Company's  agreements and representations set forth in this Agreement,  entitled
to enforce the terms thereof,  and to indemnification  for any damages resulting
to Shoreline from any actual or threatened  breach thereof by the Company,  both
in Shoreline's  personal  capacity and, should  Shoreline so elect, and provided
that Shoreline has obtained the prior written consent of the Investor, on behalf
of the Investor.

     12. Miscellaneous.

     (a) Conflicting  Instructions.  A person or entity is deemed to be a holder
of  Registrable  Securities  whenever  such person or entity owns of record such
Registrable  Securities.  If  the  Company  receives  conflicting  instructions,
notices or elections  from two or more  persons or entities  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) Notices.  Any notices required or permitted to be given under the terms
of this  Agreement  shall be sent by certified or  registered  mail (with return
receipt requested) or delivered personally or by courier (including a nationally
recognized overnight delivery service) or by facsimile transmission.  Any notice
so given shall be deemed  effective three days after being deposited in the U.S.
Mail,  or upon  receipt if  delivered  personally  or by  courier  or  facsimile
transmission, in each case addressed to a party at the following address or such
other address as each such party  furnishes to the other in accordance with this

     (c) Waiver. Failure of any party to exercise any right or remedy under this
Agreement or otherwise,  or delay by a party in exercising such right or remedy,
shall not operate as a waiver thereof.

     (d)  Governing  Law.  This  Agreement  shall be  enforced,  governed by and
construed in accordance with the laws of the State of New York applicable to the
agreements made and to be performed  entirely within such state,  without giving
effect to rules governing the conflict of laws (other than Section 5-1401,  or a
similar successor  provision,  of the New York General Obligations Law), and any
disputes  arising  hereunder  will be  adjudicated  in  federal  or state  court
situated  therein.  Each party hereto  consents to such venue in New York and to
the personal and subject matter  jurisdiction  of said courts and, to the extent
permitted  by  applicable  law,  agrees  to  waive  any  objection  as  to  such
jurisdiction  or venue,  and agrees not to assert any  defense  based on lack of
jurisdiction or venue.

     (e)  Severability.  In the event that any  provision  of this  Agreement is
invalid or unenforceable  under any applicable statute or rule of law, then such
provision  shall  be  deemed  inoperative  to the  extent  that it may  conflict
therewith  and shall be deemed  modified to conform with such statute or rule of
law. Any provision hereof which may prove invalid or unenforceable under any law
shall not affect the validity or enforceability of any other provision hereof.

     (f) Entire Agreement.  This Agreement,  the Securities  Purchase Agreement,
the  Certificate  of  Designation  and the Warrant  (including all schedules and
exhibits thereto)  constitute the entire agreement among the parties hereto with
respect to the subject  matter  hereof and thereof.  There are no  restrictions,
promises, warranties or undertakings,  other than those set forth or referred to
herein  or  therein.   This  Agreement   supersedes  all  prior  agreements  and
understandings  among the  parties  hereto with  respect to the  subject  matter
hereof.

     (g)  Successors  and  Assigns.  Subject  to the  requirements  of Section 9
hereof,  this  Agreement  shall inure to the benefit of and be binding  upon the
successors and assigns of each of the parties hereto.  Notwithstanding  anything
to the contrary herein,  including without limitation,  Section 9, the rights of
an Investor  hereunder  shall be assignable to and  exerciseable  by a bona fide
pledgee of the Registrable Securities in connection with an Investor's margin or
brokerage accounts.

                                       15

     (h) Use of Pronouns.  All pronouns and any variations  thereof refer to the
masculine, feminine or neuter, singular or plural, as the context may require.

     (i)  Headings.  The  headings  and  subheadings  in the  Agreement  are for
convenience  of  reference  only and  shall not limit or  otherwise  affect  the
meaning hereof.

     (j)   Counterparts.   This  Agreement  may  be  executed  in  two  or  more
counterparts,  each of which shall be deemed an original  but all of which shall
constitute one and the same agreement. This Agreement, once executed by a party,
may be  delivered  to the other  party  hereto by  facsimile  transmission,  and
facsimile signatures shall be binding on the parties hereto.

     (k) Further Acts. 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)  Consents.  All  consents  and other  determinations  to be made by the
Investors  pursuant to  this Agreement shall be made by the Initial  Investor or
the Investors holding a majority of the Registrable Securities, determined as if
all shares of  preferred  stock of the Company  issued in the  Offering  and all
Warrants then  outstanding  had been converted into or exercised for Registrable
Securities.

     IN WITNESS  WHEREOF,  the parties  have caused  this  Agreement  to be duly
executed as of the date first above written.

     THE SECURITIES  REPRESENTED BY THIS  CERTIFICATE  HAVE NOT BEEN  REGISTERED
UNDER  THE  SECURITIES  ACT OF  1933  ("SECURITIES  ACT"),  AS  AMENDED,  OR THE
SECURITIES  LAWS OF ANY STATE OF THE UNITED STATES.  THE SECURITIES  REPRESENTED
HEREBY MAY NOT BE OFFERED OR SOLD OR OTHERWISE  TRANSFERRED IN THE ABSENCE OF AN
EFFECTIVE  REGISTRATION STATEMENT FOR THE SECURITIES UNDER APPLICABLE SECURITIES
LAWS OR UNLESS OFFERED,  SOLD OR TRANSFERRED  PURSUANT TO AN AVAILABLE EXEMPTION
FROM THE REGISTRATION REQUIREMENTS OF THOSE LAWS.


                   COMMON STOCK PURCHASE WARRANT CERTIFICATE

                             Dated: April 24, 1998

                 to Purchase 100,000 Shares of Common Stock of

                        AMERICAN BIO MEDICA CORPORATION

     American Bio Medica  Corporation,  a New York  corporation (the "Company"),
hereby  certifies  that  CC  INVESTMENTS,   LDC,  its  permissible  transferees,
designees,  successors  and  assigns  (collectively,  the  "Holder"),  for value
received,  is entitled to purchase  from the Company at any time or from time to
time  commencing on April 24, 1998, and  terminating on April 24, 2001 up to One
Hundred Thousand (100,000) shares (each a "Share" and collectively the "Shares")
of the Company's common stock, par value $.01 per Share (the "Common Stock"), at
an exercise  price of Four Dollars and  Eighty-One  Cents ($4.81) U.S. per Share
(the  "Exercise  Price").  The number of Shares  purchasable  hereunder  and the
Exercise Price are subject to adjustment as provided in Section 4 hereof.

     1. Exercise of Warrants.

     (a) Upon  presentation  and surrender of this Common Stock Purchase Warrant
Certificate  ("Warrant  Certificate" or "Certificate"),  or lost etc. affidavit,
accompanied by a completed  Election to Purchase in the form attached  hereto as
Exhibit A (the "Election to Purchase") duly executed, at the principal office of
the Company at 102 Simons  Road, Ancramdale,  New York,  12503,  Attn:  Mr. Stan
Cipkowski, President, together with a check payable to the Company in the amount
of the Exercise Price  multiplied by the number of Shares being  purchased,  the
Company or the Company's  Transfer  Agent as the case may be, shall,  within two
(2)  trading  days of receipt of the  foregoing,  deliver to the Holder  hereof,
certificates  of  fully  paid  and  non-assessable  Common  Stock  which  in the
aggregate  represent the number of Shares being  purchased;  provided,  however,
that the  Company  may elect in  writing  to allow the  Holder  to  utilize  the
cashless  exercise  provisions set forth below in lieu of tendering the Exercise
Price in cash. The  certificates so delivered shall be in such  denominations as
may be reasonably requested by the Holder and shall be registered in the name of
the Holder or such other name as shall be designated by the Holder.  All or less
than all of the Warrants  represented by this  Certificate may be exercised and,
in case of the exercise of less than all, the Company,  upon  surrender  hereof,
will at the Company's expense deliver to the Holder a new Warrant Certificate or
Certificates  (in such  denominations as may be requested by the Holder) of like
tenor and dated the date hereof  entitling said holder to purchase the number of
Shares  represented  by this  Certificate  which have not been  exercised and to
receive  Registration  Rights with respect to such Shares,  and all other rights
with respect to the shares which the Holder has on the date hereof.

                                       1
<PAGE>


     (b) Cashless Exercise.  Notwithstanding  the foregoing  provision regarding
payment of the Exercise Price in cash, the Company may elect in writing to allow
the Holder to elect to receive a reduced  number of Shares in lieu of  tendering
the Exercise  Price in cash. In such case,  the number of Shares to be issued to
the Holder shall be computed using the following formula:

                                    X = Y(A-B)
                                    ----------
                                        A

     where: X = the number of Shares to be issued to the Holder;  Y = the number
of Shares  eligible to be  purchased  under this  Warrant  Certificate;  A = the
Market  Value  (defined  below) of one share of Common  Stock on the trading day
before the Election to Purchase and this Warrant  Certificate are duly surrender
to the Company for or partial exercise; and B = the Exercise Price.



     The term "Market Value" means, for any security as of any date, the closing
bid price of such  security  on the  principal  securities  exchange  or trading
market  where  such  security  is  listed or traded  as  reported  by  Bloomberg
Financial  Markets or a  comparable  reporting  service of  national  reputation
selected by the Company and  reasonably  acceptable  to the Holder if  Bloomberg
Financial  Markets is not then  reporting  closing  bid prices of such  security
(collectively,  "Bloomberg"),  or if the  foregoing  does  not  apply,  the last
reported  sale  price of such  security  in the  over-the-counter  market or the
electronic  bulletin board of such security as reported by Bloomberg,  or, if no
sale price is reported for such  security by  Bloomberg,  the average of the bid
prices of any market  makers for such  security as reported in the "pink sheets"
by the  National  Quotation  Bureau,  Inc. If the  Closing  Bid Price  cannot be
calculated  for such  security on such date on any of the foregoing  bases,  the
Closing Bid Price of such  security on such date shall be the fair market  value
as reasonably  determined by an investment  banking firm selected by the Company
and  reasonably  acceptable to the Holder with the costs of such appraisal to be
borne by the Company.

     2.  Exchange,  Transfer  and  Replacement.  (a) At any  time  prior  to the
exercise  hereof,  this  Certificate  may be  exchanged  upon  presentation  and
surrender  to the  Company,  alone or with other  Certificates  of like tenor of
different  denominations  registered in the name of the same Holder, for another
Certificate or Certificates of like tenor in the name of such Holder exercisable
for  the  aggregate   number  of  Shares  as  the  Certificate  or  Certificates
surrendered.

     (b) Replacement of Warrant Certificate. Upon receipt of evidence reasonably
satisfactory to the Company of the loss,  theft,  destruction,  or mutilation of
this  Warrant  Certificate  and,  in  the  case  of any  such  loss,  theft,  or
destruction,  upon delivery of an indemnity agreement reasonably satisfactory in
form and amount to the  Company,  or, in the case of any such  mutilation,  upon
surrender and  cancellation  of this Warrant  Certificate,  the Company,  at its
expense,  will execute and deliver in lieu thereof, a new Warrant Certificate of
like tenor.

     (c) Cancellation;  Payment of Expenses.  Upon the surrender of this Warrant
Certificate in connection with any transfer, exchange or replacement as provided
in this Section 2, this Warrant  Certificate  shall be promptly  canceled by the
Company.  The Company shall pay all taxes (other than securities transfer taxes)
and all other  expenses  (other  than legal  expenses,  if any,  incurred by the
Holder or transferees)  and charges payable in connection with the  preparation,
execution and delivery of Warrant Certificates pursuant to this Section 2.

     (d)  Warrant  Register.  The  Company  shall  maintain,  at  its  principal
executive  offices  (or at the  offices of the  transfer  agent for the  Warrant
Certificate or such other office or agency of the Company as it may designate by
notice to the holder  hereof),  a register  for this  Warrant  Certificate  (the
"Warrant  Register"),  in which the Company shall record the name and address of
the person in whose name this Warrant  Certificate  has been issued,  as well as
the name and address of each  permitted  transferee and each prior owner of this
Warrant Certificate.

     (e)  Exercise  Disputes.  In the case of any  dispute  with  respect  to an
exercise, the Company shall promptly issue such number of shares of Common Stock
as are not disputed in accordance  with this Section.  If such dispute  involves
the  calculation  of the Exercise  Price,  the Company shall submit the disputed
calculations  to a  "Big  Six"  independent  accounting  firm  (selected  by the
Company) via facsimile within three (3) business days of receipt of the Election
to Purchase.  The accounting  firm shall audit the  calculations  and notify the
Company and the converting  Holder of the results no later than two (2) business
days from the date it receives the disputed calculations.  The accounting firm's
calculation shall be deemed conclusive, absent manifest error. The Company shall
then issue the  appropriate  number of shares of Common Stock in accordance with
this Section.

     3. Rights and  Obligations  of Holders of this  Certificate.  The Holder of
this  Certificate  shall not, by virtue  hereof,  be entitled to any rights of a
stockholder in the Company, either at law or in equity; provided,  however, that
in the  event any  certificate  representing  shares  of  Common  Stock or other
securities  is issued to the holder  hereof upon  exercise of some or all of the
Warrants,  such holder  shall,  for all  purposes,  be deemed to have become the
holder of record of such  Common  Stock on the date on which  this  Certificate,
together with a duly executed  Purchase Form, was surrendered and payment of the
aggregate Exercise Price was made,  irrespective of the date of delivery of such
share certificate.

     4. Adjustments.

     (a) Stock  Dividends,  Reclassifications,  Recapitalizations,  Etc.  In the
event the Company:  (i) pays a dividend in Common Stock or makes a  distribution
in Common Stock,  (ii)  subdivides its  outstanding  Common Stock into a greater
number of shares,  (iii)  combines its  outstanding  Common Stock into a smaller
number of shares or (iv)  increases or decreases  the number of shares of Common
Stock  outstanding  by   reclassification  of  its  Common  Stock  (including  a
recapitalization  in  connection  with a  consolidation  or  merger in which the
Company  is the  continuing  corporation),  then (1) the  Exercise  Price on the
record  date of such  division or  distribution  or the  effective  date of such
action shall be adjusted by multiplying  such Exercise Price by a fraction,  the


                                       3
<PAGE>

numerator  of  which  is the  number  of  shares  of  Common  Stock  outstanding
immediately  before  such  event and the  denominator  of which is the number of
shares of Common Stock  outstanding  immediately  after such event,  and (2) the
number of shares of Common  Stock  for which  this  Warrant  Certificate  may be
exercised  immediately  before such event shall be adjusted by multiplying  such
number by a fraction,  the numerator of which is the Exercise Price  immediately
before such event and the denominator of which is the Exercise Price immediately
after such event.

     (b) Cash Dividends and Other  Distributions.  In the event that at any time
or from time to time the Company shall distribute to all holders of Common Stock
(i) any dividend or other  distribution of cash,  evidences of its indebtedness,
shares of its capital  stock or any other  properties  or securities or (ii) any
options,  warrants  or other  rights to  subscribe  for or  purchase  any of the
foregoing  (other  than in each case,  (w) the  issuance  of any rights  under a
shareholder  rights plan, (x) any dividend or distribution  described in Section
4(a), (y) any rights, options,  warrants or securities described in Section 4(c)
and (z) any cash dividends or other cash  distributions  from current earnings),
then the number of shares of Common  Stock  issuable  upon the  exercise of each
Warrant Certificate shall be increased to a number determined by multiplying the
number of shares of Common  Stock  issuable  upon the  exercise of such  Warrant
Certificate  immediately  prior to the  record  date for any  such  dividend  or
distribution  by a fraction,  the  numerator of which shall be such Market Value
per share of Common Stock on the record date for such dividend or  distribution,
and the  denominator  of which  shall be such  Market  Value per share of Common
Stock on the record date for such dividend or  distribution  less the sum of (x)
the amount of cash,  if any,  distributed  per share of Common Stock and (y) the
fair  value  (as  determined  in good  faith by the  Board of  Directors  of the
Company, whose determination shall be evidenced by a board resolution, a copy of
which will be sent to the Holders upon  request) of the portion,  if any, of the
distribution  applicable to one share of Common Stock consisting of evidences of
indebtedness,  shares of stock, securities, other property, warrants, options or
subscription or purchase  rights;  and the Exercise Price shall be adjusted to a
number  determined  by dividing the  Exercise  Price  immediately  prior to such
record date by the above fraction.  Such adjustments  shall be made whenever any
distribution is made and shall become  effective as of the date of distribution,
retroactive to the record date for any such distribution. No adjustment shall be
made pursuant to this Section 4(b) which shall have the effect of decreasing the
number  of shares  of  Common  Stock  issuable  upon  exercise  of each  Warrant
Certificate or increasing the Exercise Price.

     (c)  Rights  Issue.  In the event that at any time or from time to time the
Company shall issue rights, options or warrants entitling the holders thereof to
subscribe  for  shares  of  Common  Stock,  or  securities  convertible  into or
exchangeable  or  exercisable  for Common  Stock to all holders of Common  Stock
(other than in connection with the adoption of a shareholder  rights plan by the
Company) without any charge, entitling such holders to subscribe for or purchase
shares of Common  Stock at a price per share that as of the record date for such
issuance  is less than the then  Market  Value per  share of Common  Stock,  the
number of shares of Common  Stock  issuable  upon the  exercise of each  Warrant
Certificate  shall be increased to a number determined by multiplying the number
of shares of Common Stock  theretofore  issuable  upon  exercise of each Warrant
Certificate by a fraction,  the numerator of which shall be the number of shares
of Common Stock  outstanding  on the date of issuance of such  rights,  options,
warrant or  securities  plus the  number of  additional  shares of Common  Stock


                                       6
<PAGE>

offered for  subscription  or purchase or into or for which such securities that
are issued are convertible,  exchangeable or exercisable, and the denominator of
which shall be the number of shares of Common Stock  outstanding  on the date of
issuance of such rights, option, warrants or securities plus the total number of
shares of Common Stock which the aggregate consideration expected to be received
by the Company (assuming the exercise or conversion of all such rights, options,
warrants or  securities)  would  purchase at the then Market  Value per share of
Common Stock. In the event of any such  adjustment,  the Exercise Price shall be
adjusted to a number determined by dividing the Exercise price immediately prior
to such date of issuance by the aforementioned  fraction.  Such adjustment shall
be made immediately after such rights,  options or warrants are issued and shall
become  effective,  retroactive  to the  record  date for the  determination  of
stockholders entitled to receive such rights,  options,  warrants or securities.
No  adjustment  shall be made pursuant to this Section 4(c) which shall have the
effect of  decreasing  the  number of shares of Common  Stock  purchasable  upon
exercise or each Warrant Certificate or of increasing the Exercise Price.

     (d) Combination; Liquidation.

     (i) If the Company shall consolidate with or merge into another corporation
or  reclassify  its  outstanding  shares of Common  Stock  (other than by way of
subdivision or reduction of such shares) (each a "Major Transaction"), then each
Holder  of a  Warrant  Certificate  shall  thereafter  be  entitled  to  receive
consideration,  in exchange for such Warrant  Certificate,  equal to the greater
of, as  determined  in the sole  discretion  of such  Holder:  (1) a warrant  to
purchase  (at the  same  aggregate  exercise  price  and on the same  terms  and
conditions as the Warrant Certificate surrendered) the number of shares of stock
or securities or property of the Company,  or of the entity  resulting from such
consolidation  or merger (the  "Major  Transaction  Consideration"),  to which a
holder of the number of shares of Common Stock  delivered  upon exercise of such
Warrant Certificate would have been entitled upon such Major Transaction had the
Holder of such Warrant Certificate  exercised (without regard to any limitations
on exercise  herein  contained)  the  Warrant  Certificate  on the trading  date
immediately  preceding the public  announcement of the transaction  resulting in
such Major Transaction and had such Common Stock been issued and outstanding and
had such Holder  been the holder of record of such  Common  Stock at the time of
such Major Transaction,  and the Company shall make lawful provision therefor as
a part of such consolidation,  merger or reclassification;  and (2) cash paid by
the  Company  in  immediately  available  funds,  in  an  amount  equal  to  the
Black-Scholes  Amount (as defined  herein)  times the number of shares of Common
Stock for which this Warrant Certificate was exercisable  (without regard to any
limitations on exercise herein contained) on the date immediately  preceding the
date of such Major Transaction. No sooner than ten (10) days nor later than five
(5) days prior to the  consummation of the Major  Transaction,  but not prior to
the public  announcement  of such Major  Transaction,  the Company shall deliver
written  notice  ("Notice  of Major  Transaction")  to each  Holder  of  Warrant
Certificates,  which  Notice of Major  Transaction  shall be deemed to have been
delivered one (1) business day  following  the Company's  sending such notice by
telecopy  (provided  that the Company sends a confirming  copy of such notice on
the same day by  overnight  courier) of such Notice of Major  Transaction.  Such
Notice of Major  Transaction  shall  indicate  the  amount and type of the Major
Transaction  Consideration  which such Holder would  receive under clause (1) of
this  paragraph  (d). If the Major  Transaction  Consideration  does not consist
entirely of United  States  currency,  such  Holder may elect to receive  United
States  currency  in an  amount  equal  to the  value of the  Major  Transaction
Consideration  in lieu of the  Major  Transaction  Consideration  by  delivering
notice of such  election  of the Company  within  five (5) days of the  Holder's
receipt of the Notice of Major Transaction.

                                       5
<PAGE>

     The "Black-Scholes Amount" shall be an amount determined by calculating the
"Black-Scholes"  value of an option to purchase one share of Common Stock on the
applicable  page on the  Bloomberg  online page,  using the  following  variable
values:  (1) the current  market  price of the Common Stock equal to the closing
trade  price on the last  trading day before the date of the Notice of the Major
Transaction;  (2)  volatility of the Common Stock equal to the volatility of the
Common Stock during the 100 trading day period  preceding the date of the Notice
of the Major Transaction; (3) a risk free rate equal to the interest rate on the
United States  treasury bill or treasury note with a maturity  corresponding  to
the remaining  term of the Warrant  Certificate on the date of the Notice of the
Major Transaction;  and (4) an exercise price equal to the Exercise Price on the
date of the  Notice of the Major  Transaction.  In the  event  such  calculation
function is no longer available  utilizing the Bloomberg online page, the Holder
shall calculate such amount in its sole discretion  using the closest  available
alternative  mechanism  and variable  values to those  available  utilizing  the
Bloomberg online page for such calculation function.

     (ii)  Notwithstanding  (i) above,  in the event of (x) a Combination  where
consideration  to the holders of Common  Stock in exchange  for their  shares is
payable solely in cash or (y) the dissolution,  liquidation or winding-up of the
Company,  the Holders  shall be entitled to  receive,  upon  surrender  of their
Warrant Certificates, distributions on an equal basis with the holders of Common
Stock or other securities issuable upon exercise of the Warrant Certificates, as
if the Warrant Certificates had been exercised  immediately prior to such event,
less the Exercise Price.  In case of any  Combination  described in this Section
4(d)(ii),   the  surviving  or  acquiring  Person  and,  in  the  event  of  any
dissolution,  liquidation  or  winding-up  of the Company,  the  Company,  shall
deposit  promptly  following the consummation of such combination or at the time
of such dissolution,  liquidation or winding-up with an agent or trustee for the
benefit of the Holders of the funds, if any, necessary to pay to the Holders the
amounts to which they are entitled as described above.  After such funds and the
surrendered  Warrant  Certificates  are  received,  the  Company is  required to
deliver  a  check  in  such  amount  as is  appropriate  (or,  in  the  case  of
consideration  other than cash, such other  consideration  as is appropriate) to
such  Person  or  Persons  as it may  be  directed  in  writing  by the  Holders
surrendering such Warrant Certificates.

     (e) Notice of  Adjustment.  Whenever  the  Exercise  Price or the number of
shares of Common Stock and other property, if any, issuable upon exercise of the
Warrant Certificates is adjusted, as herein provided,  the Company shall deliver
to the holders of the  Warrant  Certificates  in  accordance  with  Section 10 a
certificate  of  the  Company's  Chief  Financial   Officer  setting  forth,  in
reasonable  detail,  the event  requiring the adjustment and the method by which
such  adjustment was  calculated  (including a description of the basis on which
(i) the  Board of  Directors  determined  the fair  value  of any  evidences  of
indebtedness,  other  securities  or  property  or  warrants,  options  or other
subscription  or purchase  rights and (ii) the then  Market  Value of the Common
Stock was  determined,  if either of such  determinations  were  required),  and
specifying the Exercise Price and number of shares of Common Stock issuable upon
exercise of Warrant Certificates after giving effect to such adjustment.

                                       7
<PAGE>

     (f)  Purchase  Price  Adjustment.  In the event that the Company  issues or
sells any Common Stock or securities  which are convertible into or exchangeable
for its Common  Stock or any  convertible  securities,  or any warrants or other
rights to  subscribe  for or to purchase or any options for the  purchase of its
Common Stock or any such  convertible  securities  (other than shares or options
issued or which may be issued  pursuant  to the  Company's  employee or director
option  plans or shares  issued upon  exercise  of  options,  warrants or rights
outstanding on the date of the Agreement and listed in the Company's most recent
periodic  report  filed under the  Exchange  Act) and other than the  Additional
Financing (as defined in the Purchase  Agreement) at an effective purchase price
per share which is less than the greater of the Purchase Price then in effect or
the Market  Value of the Common  Stock on the  trading day next  preceding  such
issue or sale, then in each such case, the Exercise Price in effect  immediately
prior to such issue or sale shall be reduced  effective  concurrently  with such
issue or sale to an amount  determined by multiplying the Exercise Price then in
effect by a  fraction,  (x) the  numerator  of which shall be the sum of (1) the
number of shares of Common Stock outstanding  immediately prior to such issue or
sale,  plus (2) the  number  of  shares of  Common  Stock  which  the  aggregate
consideration  received by the Company for such additional shares would purchase
at such fair market value or, Exercise Price as the case may be, then in effect;
and (y) the  denominator  of which shall be the number of shares of Common Stock
of the Company outstanding immediately after such issue or sale.

     For the purposes of the foregoing  adjustment,  in the case of the issuance
of any convertible  securities,  warrants,  options or other rights to subscribe
for or to  purchase  or  exchange  for,  shares  of Common  Stock  ("Convertible
Securities"),  the  maximum  number  of shares of  Common  Stock  issuable  upon
exercise,  exchange or conversion of such Convertible Securities shall be deemed
to be outstanding,  provided that no further  adjustment  shall be made upon the
actual  issuance of Common Stock upon  exercise,  exchange or conversion of such
Convertible Securities.

     If the  Company in any manner  issues or sells any  Convertible  Securities
with a fluctuating  conversion or exercise  price or exchange ratio (a "Variable
Rate Convertible Security"),  then the price per share for which Common Stock is
issuable  upon  such  exercise,  conversion  or  exchange  for  purposes  of the
calculation  contemplated  pursuant  to this  Section  shall be deemed to be the
lowest price per share which would be  applicable  assuming that (i) all holding
period and other  conditions  to any  discounts  contained  in such  Convertible
Security have been satisfied,  and (ii) the Market Price on the date of issuance
of such  Convertible  Security  was 80% of the  Market  Price on such  date (the
"Assumed Variable Market Price").

     The number of shares  which may be purchased  hereunder  shall be increased
proportionately  to any reduction in Exercise  Price  pursuant to this paragraph
4(f),  so that after such  adjustments  the  aggregate  Exercise  Price  payable
hereunder for the increased  number of shares shall be the same as the aggregate
Exercise Price in effect just prior to such adjustment.

     In the event of any such  issuance for a  consideration  which is less than
such fair  market  value and also less than the  Exercise  Price then in effect,
than there shall be only one such  adjustment by reason of such  issuance,  such
adjustment  to be that which  results in the greatest  reduction of the Purchase
Price computed as aforesaid.

                                       8

     (g) Notice of Certain  Transactions.  In the event that the  Company  shall
propose  (a) to pay any  dividend  payable  in  securities  of any  class to the
holders  of  its  Common  Stock  or to  make  any  other  non-cash  dividend  or
distribution to the holders of its Common Stock, (b) to offer the holders of its
Common Stock rights to subscribe for or to purchase any  securities  convertible
into  shares  of  Common  Stock or  shares  of stock of any  class or any  other
securities,  rights  or  options,  (c) to  effect  any  capital  reorganization,
reclassification,  consolidation  or merger affecting the class of Common Stock,
as a  whole,  or  (d)  to  effect  the  voluntary  or  involuntary  dissolution,
liquidation  or winding-up of the Company,  the Company  shall,  within the time
limits specified below,  send to each Holder a notice of such proposed action or
offer.  Such notice  shall be mailed to the Holders at their  addresses  as they
appear in the Warrant Register (as defined in Section 2(d)), which shall specify
the record date for the purposes of such dividend,  distribution  or rights,  or
the date such  issuance or event is to take place and the date of  participation
therein by the  holders of Common  Stock,  if any such date is to be fixed,  and
shall  briefly  indicate  the  effect of such  action on the number of shares of
Common  Stock and on the  number  and kind of any  other  shares of stock and on
other  property,  if any,  and the  number of  shares of Common  Stock and other
property,  if any,  issuable upon exercise of each Warrant  Certificate  and the
Exercise Price after giving effect to any adjustment pursuant to Section 4 which
will be  required  as a result of such  action.  Such  notice  shall be given as
promptly as possible and (x) in the case of any action  covered by clause (a) or
(b) above, at least 10 days prior to the record date for determining  holders of
the Common  Stock for  purposes  of such  action or (y) in the case of any other
such action,  at least 20 days prior to the date of the taking of such  proposed
action or the date of  participation  therein by the  holders  of Common  Stock,
whichever shall be the earlier.

     (h) Other  Adjustments.  In the event of any other  transaction of the type
contemplated by this Section 4, but not expressly provided for by the provisions
hereof,  the Board of Directors of the Company will make appropriate  adjustment
in the Exercise  Price and the number of Shares so as to  equitably  protect the
rights of the Holder.

     (i) No Impairment of Holder's Rights. The Company will not, by amendment of
its  certificate  of  incorporation  or bylaws or  through  any  reorganization,
transfer  of  assets,  consolidation,  merger,  dissolution,  issue  or  sale of
securities or any other voluntary action,  except as contemplated  hereby, avoid
or seek to avoid  the  observance  or  performance  of any of the  terms of this
Warrant Certificate,  but will at all times in good faith assist in the carrying
out of all such  terms and in the taking of all  action as may be  necessary  or
appropriate  in order to protect  the rights of the Holder  against  dilution or
other impairment.

                                       9

     5. Certain Agreements of the Company.

     (a) The  Company  covenants  and  agrees  that all  shares of Common  Stock
issuable upon exercise of this Warrant Certificate will, upon delivery,  be duly
and validly  authorized and issued,  fully-paid and non-assessable and free from
all taxes, liens, claims and encumbrances.

     (b) The Company  covenants and agrees that it will at all times reserve and
keep  available  an  authorized  number of shares of its Common  Stock and other
applicable  securities  sufficient  to  permit  the  exercise  in  full  of  all
outstanding options, warrants and rights, including this Warrant Certificate.

     (c) The Company shall  promptly  secure the listing of the Shares upon each
national  securities  exchange or automated quotation system, if any, upon which
shares of Common  Stock are then  listed or become  listed  (subject to official
notice  of  issuance  upon  exercise  of this  Warrant  Certificate)  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  Certificate;  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 Certificate if and so long as
any  shares  of the same  class  shall be  listed  on such  national  securities
exchange or automated quotation system.

     (d) The Company has taken all necessary  action and proceedings as required
and  permitted  by  applicable  law,  rule and  regulation,  including,  without
limitation,  the  notification of the principal market on which the Common Stock
is traded,  for the legal and valid issuance of this Warrant  Certificate to the
Holder under this Warrant Certificate.

     (e) With a view to making  available  to Holder  the  benefits  of Rule 144
promulgated under the Act and any other rule or regulation of the Securities and
Exchange  Commission  ("SEC")  that  may at  any  time  permit  Holder  to  sell
securities of the Company to the public without registration, the Company agrees
to use its commercially reasonable efforts to:

     (i) make and keep current  public  information  available,  as this term is
understood and defined in Rule 144 under the Securities Act, at all times;

     (ii) file with the SEC in a timely  manner all reports and other  documents
required of the Company under the Securities Act and the Securities Exchange Act
of 1934, as amended (the "Exchange Act"); and

     (iii) furnish to any Holder  forthwith upon request a written  statement by
the Company that it has complied with the reporting requirements of Rule 144 and
of the Act and the Exchange  Act, a copy of the most recent  annual or quarterly
report of the  Company,  and such other  reports and  documents  so filed by the
Company  as may be  reasonably  requested  to  permit  any such  Holder  to take
advantage of any rule or  regulation  of the SEC  permitting  the selling of any
such securities without registration.

                                       10
<PAGE>

     6.  Registration  Rights.  The initial Holder is entitled to the benefit of
such  registration  rights  in  respect  of the  Shares  as are set forth in the
Registration  Rights  Agreement  dated as of April 23, 1998,  by and between the
Company  and the  Holder,  including  the right to assign such rights to certain
assignees as set forth therein.

     7. Issuance of Certificates.  Within three (3) trading days of receipt of a
duly completed  Election to Purchase form,  together with this  Certificate  and
payment of the Exercise  Price,  the Company,  at its expense,  will cause to be
issued in the name of and delivered to the Holder of this Warrant, a certificate
or certificates for the number of fully paid and non-assessable shares of Common
Stock to which that Holder shall be entitled on such exercise.  In the event the
shares of Common  Stock are not timely  delivered  to the  Holder,  the  Company
agrees to (a)  indemnify  Holder for all damages,  including  consequential  and
special  damages,  lost  profits and  expenses,  including  legal fees,  and (b)
beginning on the fifth (5th) trading day  following  the Company's  receipt of a
duly completed Election to Purchase form, pay a default premium of 2% per day of
the value of underlying  shares  (based on the highest  closing price during the
two (2) day period preceding the date of surrender of the Warrant  Certificate).
In lieu of issuance  of a  fractional  share upon any  exercise  hereunder,  the
Company  will pay the cash value of that  fractional  share,  calculated  on the
basis of the Exercise  Price.  Prior to registration of the resale of the shares
of Common Stock underlying this Warrant Certificate, all such certificates shall
bear a  restrictive  legend  consistent  with that  specified in the  Securities
Purchase Agreement.

     8.  Disposition  of  Warrants  or  Shares.   The  Holder  of  this  Warrant
Certificate, each transferee hereof and any holder and transferee of any Shares,
by his or its acceptance thereof, agrees that no public distribution of Warrants
or Shares will be made in violation of the  provisions  of the  Securities  Act.
Furthermore,  it shall be a condition to the  transfer of the Warrants  that any
transferee thereof deliver to the Company his or its written agreement to accept
and be bound by all of the  relevant  terms  and  conditions  contained  in this
Warrant Certificate.

     9. Merger or Consolidation.  The Company will not merge or consolidate with
or into any other  corporation,  or sell or  otherwise  transfer  its  property,
assets and business substantially as an entirety to another corporation,  unless
the  corporation  resulting  from  such  merger  or  consolidation  (if  not the
Company),  or such transferee  corporation,  as the case may be, shall expressly
assume, by supplemental agreement reasonably  satisfactory in form and substance
to the Holder, the due and punctual performance and observance of each and every
covenant and condition of this Warrant  Certificate to be performed and observed
by the Company.

     Notwithstanding  the time of  effectiveness  of  notices  set forth in this
Section,  an Election to Purchase shall not be deemed effectively given until it

Warrant  Certificate  to be  exercised  and payment of the  Exercise  Price in a
manner set forth in this Section.

     11.  Notwithstanding  anything in this Warrant Certificate to the contrary,
in no event shall the holder of this Warrant Certificate be entitled to exercise
a number of Warrant  Certificates (or portions  thereof) in excess of the number
of Warrant  Certificates (or portions thereof) upon exercise of which the sum of
(i) the number of shares of Common  Stock  beneficially  owned by the holder and
its  affiliates  (other  than  shares  of  Common  Stock  which  may  be  deemed
beneficially owned through the ownership of the unexercised Warrant Certificates
and unconverted shares of Preferred Stock (as defined in the Securities Purchase
Agreement))  or  other  securities  containing  restrictions  on  conversion  or
exercise  analogous to the provisions in this paragraph,  and (ii) the number of
shares of Common Stock  issuable upon exercise of the Warrant  Certificates  (or
portions  thereof) with respect to which the  determination  described herein is
being  made,  would  result  in  beneficial  ownership  by the  holder  and  its
affiliates of more than 4.99% of the  outstanding  shares of Common  Stock.  For
purposes of the immediately  preceding sentence,  (x) beneficial ownership shall
be  determined  in  accordance  with  Section  13(d)  of the  Exchange  Act  and
Regulation 13D-G thereunder,  except as otherwise provided in clause (i) hereof,
and (y) a holder may waive the  limitations  set forth herein upon not less than
sixty-one (61) days prior written notice to the Company (with such waiver taking
effect only upon the expiration of such sixty-one (61) day notice period).

     12. Governing Law. This Warrant  Certificate and all rights and obligations
hereunder shall be deemed to be made under and governed by the laws of the State
of New York  without  giving  effect to the  conflicts of laws  provisions.  The
Holder hereby  irrevocably  consents to the venue and  jurisdiction of the State
and Federal Courts located in the State of New York, County of New York.

     13. Successors and Assigns.  This Warrant Certificate shall be binding upon
and shall  inure to the  benefit  of the  parties  hereto  and their  respective
successors and permitted assigns.

     14. Headings.  The headings of various sections of this Warrant Certificate
have been  inserted  for  reference  only and shall not  affect  the  meaning or
construction of any of the provisions hereof.

     15.  Severability.  If any provision of this Warrant Certificate is held to
be  unenforceable  under  applicable  law, such provision shall be excluded from
this Warrant Certificate, and the balance hereof shall be interpreted as if such
provision were so excluded.

     16.  Modification  and Waiver.  This Warrant  Certificate and any provision
hereof may be amended, waived, discharged or terminated only by an instrument in
writing signed by the Company and the Holder.

     17. Specific Enforcement.  The Company and the Holder acknowledge and agree
that  irreparable  damage would occur in the event that any of the provisions of
this Warrant  Certificate  were not performed in accordance  with their specific
terms or were  otherwise  breached.  It is  accordingly  agreed that the parties
shall be entitled to an injunction or injunctions to prevent or cure breaches of
the provisions of this Warrant Certificate and to enforce specifically the terms
and  provisions  hereof,  this being in  addition  to any other  remedy to which
either of them may be entitled by law or equity.

     18. Assignment. This Warrant Certificate may be transferred or assigned, in
whole or in  part,  at any time  and  from  time to time by the then  Holder  by
submitting this Warrant to the Company together with a duly executed  Assignment
in  substantially  the  form  and  substance  of the  Form of  Assignment  which
accompanies this Warrant Certificate and, upon the Company's receipt hereof, and
in any event, within three (3) business days thereafter, the Company shall issue
a Warrant  Certificate  to the Holder to evidence  that  portion of this Warrant
Certificate,  if any as shall  not have  been so  transferred  or  assigned.  In
addition, and notwithstanding anything to the contrary contained in this Warrant
Certificate,  this Warrant Certificate may be pledged,  and all rights of Holder
under this Warrant  Certificate may be assigned,  without further consent of the
Company,  to a bona fide pledgee in connection with Holder's margin or brokerage
accounts.

     18.  Issue Tax.  The  issuance  of Common  Stock upon the  exercise of this
Warrant  Certificate  shall be made without charge to the holder of this Warrant
Certificate  or such  shares  for any  issuance  tax or other  costs in  respect
thereof,  provided  that the Company  shall not be required to pay any tax which
may be payable in respect of any transfer  involved in the issuance and delivery
of any certificate in a name other than the Holder.

     IN WITNESS WHEREOF,  the Company has caused this Warrant  Certificate to be
duly executed,  manually or by facsimile,  by one of its officers thereunto duly
authorized.

consists of Four  Thousand  Five Hundred  (4,500)  shares of Preferred  Stock of
American  Bio  Medica  Corporation,  a New York  corporation  together  with any
additional  shares of  Preferred  Stock  issued as a dividend  or  otherwise  in
payment of obligations  hereunder,  not to exceed, in the aggregate Six Thousand
(6,000)  shares,  is the  Series D  Preferred  Stock (the  "Preferred  Stock" or
"Preferred  Shares") and the face amount per share shall equal One Thousand U.S.
Dollars ($1,000) (the "Face Amount").

                                  II. DIVIDENDS

A.   General.  The holders of the  Preferred  Stock shall be entitled to receive
     cumulative  dividends at the rate of eight  percent (8%) of the Face Amount
     per annum (the  "Dividend").  Such  cumulative  Dividends  shall be payable
     quarterly  in arrears  within three  Business  Days of the last day of each
     April,  July,  October  and  January,  commencing  July,  1998,  in cash or
     additional  Preferred  Shares,  at the Company's  option.  Dividends on the
     Preferred  Stock shall accrue and be  cumulative  on a daily basis from the
     date of issuance  (with  appropriate  proration  for any  partial  dividend
     period),  whether or not earned and whether or not in any  dividend  period
     there shall be surplus or net profits of the Company legally  available for
     the payment of such dividends.

B.   Payment of Dividend in Preferred  Shares.  Should the Company  elect to pay
     accrued but unpaid  Dividends in additional  shares of Preferred Stock, the
     number of Preferred  Shares to which the Holder  shall be entitled  will be
     equal to the aggregate cash value of such unpaid Dividends,  divided by the
     Face Amount.

C.   Dividend  Adjustment.  Following the Effective Date, if the average Closing
     Bid Price of the  Common  Stock  over any 20  consecutive  trading  days is
     greater than 145% of the Closing  Price,  the Dividend  will  thereafter be
     reduced  from eight  percent  (8%) to five  percent  (5%) per  annum,  with
     appropriate pro-ration for partial dividend periods.

                                 IV. CONVERSION

     A.  Conversion at the Option of Holder.  Beginning on the earliest to occur
of (i) the Effective Date, (ii) the Registration Deadline,  (iii) the occurrence
of any event or  circumstance  that,  with the  passing of time or the giving of
notice,  would  constitute a  Redemption  Event,  and (iv) any Material  Adverse
Change, each Holder may, at any time and from time to time convert any or all of
its shares of  Preferred  Stock  into a number of fully  paid and  nonassessable
shares of Common Stock  determined by dividing the aggregate  Face Amount of the
Preferred  Shares being converted by the Conversion  Price. The Conversion Price
is subject to adjustment as provided in Article X.

     B.  Mechanics of  Conversion.  To convert the  Preferred  Shares,  a Holder
shall: (i) fax (or otherwise  deliver by other means resulting in notice) a copy
of the fully  executed  Notice of  Conversion in the form of Exhibit A hereto to
the Company and (ii) within  three (3)  Business  Days  surrender or cause to be
surrendered  to the Company (or satisfy the  provisions of Section  XIII(A),  if
applicable) the  certificates  representing  the Preferred Stock being converted
(the "Preferred Stock  Certificates")  accompanied by duly executed stock powers
and the original  executed version of the Notice of Conversion.  The date of the
Company's  receipt of the Notice of Conversion  described in clause (i) shall be
the "Conversion Date".

     C.  Conversion  Disputes.  In the case of any  dispute  with  respect  to a
conversion,  the Company  shall  promptly  issue such number of shares of Common
Stock as are not  disputed  in  accordance  with the  other  provisions  of this
Article IV. If such dispute  involves the  calculation of the Conversion  Price,
the Company shall submit the disputed calculations to an independent  accounting
firm of national  standing,  acceptable to Holder,  via facsimile within two (2)
Business Days of receipt of the Notice of Conversion.  The accounting firm shall
audit the  calculations  and notify the Company and the Holder of the results no
later  than  two (2)  Business  Days  from  the date it  receives  the  disputed
calculations.  The accounting  firm's  calculation  shall be deemed  conclusive,
absent  manifest error.  The Company shall then issue the appropriate  number of
shares of Common Stock in accordance with this Article IV.

     D. Timing of Conversion. No later than the third Business Day following the
Conversion Date (the "Delivery Period"),  provided that the Company has received
prior to such date the Preferred Stock Certificates (or the Holder has satisfied
the provisions of Section XIII(A), if applicable),  the Company shall deliver to
the  Holder  (or at its  direction)  (x) that  number of shares of Common  Stock
issuable upon  conversion of the number of Preferred  Shares being converted and
(y) a  certificate  representing  the  number  of  Preferred  Shares  not  being
converted,  if any. The person or persons  entitled to receive  shares of Common
Stock  issuable  upon such  conversion  shall be treated for all purposes as the
record holder of such shares at the close of business on the Conversion Date and
such shares  shall be issued at such time,  unless the Notice of  Conversion  is
revoked as provided in Section  IV(D).  The  Delivery  Period  shall be extended
until the  Business  Day  following  the date of  delivery to the Company of the
Preferred  Stock  Certificates to be converted or satisfaction of the provisions
of Section XIII(A), if applicable.

                                       3
<PAGE>

     E.  Revocation of Notice of  Conversion.  In addition to any other remedies
which may be  available  to the Holder,  in the event the Company  fails for any
reason to effect delivery to the Holder of certificates  representing the shares
of Common Stock  receivable upon conversion of the Preferred  Shares (or, solely
as  expressly  permitted  pursuant to Sections  V(B) and V(E),  to effect a Cash
Conversion  (as defined  below)) by the Business Day following the expiration of
the Delivery Period (which  certificates shall be unlegended after the Effective
Date),  the Holder may revoke the Notice of Conversion by delivering a notice to
such effect to the  Company.  Upon  receipt by the Company of such a  revocation
notice,  the  Company  shall  immediately  return the  subject  Preferred  Stock
certificates and other conversion documents, if any, delivered by Holder, to the
Holder,  and the  Company  and  the  Holder  shall  each be  restored  to  their
respective  positions  held  immediately  prior to  delivery  of the  Notice  of
Conversion;  provided however,  that the Company shall remain liable for payment
of the amounts determined  pursuant to Section VI(A) hereof for each day falling
between  the  trading  day  following  the  Delivery  Period and the date of the
revocation  notice is received by the Company,  and shall also remain liable for
any damages suffered by Holder.

     F.  Mandatory  Conversion.  Notwithstanding  the other  provisions  of this
Article IV, if on or after the Effective  Date the average  closing bid price of
the Common  Stock over any 20  consecutive  trading  days is equal to or greater
than  300% of the  Closing  Price,  all  outstanding  Preferred  Shares  will be
automatically  converted  into shares of Common  Stock at the lowest  Conversion
Price in effect on such 20th trading day, so long as, on the date of  conversion
and for the 10  consecutive  trading days prior to such date,  (i) the shares of
Common Stock issued pursuant to such mandatory conversion are (a) authorized and
reserved for  issuance,  (b)  registered  under the  Securities  Act of 1933, as
amended,  for resale by the Holder  subject to such  conversion,  and registered
under  the  Securities  Exchange  Act of 1934 and (c)  eligible  to be traded on
either the Nasdaq National Market System,  the Nasdaq Small Cap Market,  the New
York Stock  Exchange,  the American Stock  Exchange,  or any successor  national
exchange,  (ii) no event or  circumstance  has occurred that, with the giving of
notice or the passage of time,  would  constitute a Redemption Event (as defined
below),  (iii) such conversion  would not result in any Holder holding shares in
excess of the 4.9% Limitation (as defined  below),  and (iv) the Company has not
disclosed to the Holder any material  non-public  information about the Company.
The  Company  shall give the  Holders  three (3)  Business  Days'  notice of any
mandatory conversion pursuant to this Section IV(F).

     G. Maturity;  Required Redemption.  All Preferred Shares outstanding on the
third  anniversary  of the  Closing  Date will be  redeemed on such date in cash
equal to the  aggregate  Face Amount  thereof.  To the extent that the Preferred
Shares are not so  redeemed  in cash on such date,  the Holder may  continue  to
convert  such  Preferred  Shares  in  accordance  with the  other  terms of this
Certificate of Designation.

     H. Stamp,  Documentary  and Other Similar Taxes.  The Company shall pay all
stamp,  documentary,  issuance and other similar taxes which may be imposed with
respect to the issuance  and delivery of the shares of Common Stock  pursuant to
conversion  of the  Preferred  Stock;  provided  that  the  Company  will not be
obligated to pay stamp,  transfer or other taxes  resulting from the issuance of
Common Stock to any person  other than the  registered  holder of the  Preferred
Stock.

                                       4
<PAGE>

     I. No Fractional  Shares.  No  fractional  shares of Common Stock are to be
issued upon the conversion of Preferred  Stock, but the Company shall pay a cash
adjustment in respect of any fractional  share which would otherwise be issuable
in an  amount  equal  to the  same  fraction  of the  Closing  Bid  Price on the
Conversion  Date of a share of Common  Stock;  provided  that in the event  that
sufficient  funds  are not  legally  available  for  the  payment  of such  cash
adjustment any fractional shares of Common Stock shall be rounded up to the next
whole number.

     J. Electronic  Transmission.  In lieu of delivering  physical  certificates
representing the Common Stock issuable upon  conversion,  provided the Company's
transfer agent is  participating  in the Depository  Trust Company  ("DTC") Fast
Automated  Securities  Transfer program (the "FAST Program"),  upon request of a
Holder  who shall have  previously  instructed  such  Holder's  prime  broker to
confirm  such  request to the  Company's  transfer  agent and upon the  Holder's
compliance with Section IV(B), the Company shall use its commercially reasonable
efforts to cause its transfer agent to electronically  transmit the Common Stock
issuable  upon  conversion  to the Holder by  crediting  the account of Holder's
prime broker with DTC through its Deposit  Withdrawal Agent Commission  ("DWAC")
system.  Subject  to the  foregoing,  the  Company  will  use  its  commercially
reasonable  efforts to maintain the eligibility of its Common Stock for the FAST
Program.

     K.  Five  Percent  Holdings.   Notwithstanding  anything  to  the  contrary
contained  herein,  the Preferred  Stock shall not be convertible by a Holder to
the extent (but only to the extent) that, if  convertible  by such Holder,  such
Holder,  or any of its affiliates (as defined under Rule 12b-2 of the Securities
Exchange Act of 1934, as amended),  would  beneficially own in excess of 4.9% of
the shares of Common Stock (the "4.9% Limitation").  To the extent the foregoing
limitation  applies,  the  determination  of whether  Preferred  Stock  shall be
convertible  (vis-a-vis  other  securities  owned by such  Holder)  and of which
Preferred Stock shall be convertible (as among shares of Preferred  Stock) shall
be in the sole  discretion of the Holder and  submission of the Preferred  Stock
for conversion shall be deemed to be the Holder's  determination of whether such
Preferred Stock is convertible (vis-a-vis other securities owned by such Holder)
and of which  shares of  Preferred  Stock are  convertible  (as among  shares of
Preferred  Stock),  subject to such aggregate  percentage  limitation.  No prior
inability to convert  Preferred  Stock  pursuant to this Section  shall have any
effect on the  applicability  of the  provisions of this Section with respect to
any  subsequent  determination  of  convertibility.  For  the  purposes  of this
Section, beneficial ownership and all determinations and calculations, including
without limitation,  with respect to calculations of percentage ownership, shall
be made in accordance with Section 13(d) of the Securities Exchange Act of 1934,
as amended, and regulation 13D and G thereunder.  The provisions of this Section
may be implemented  in a manner  otherwise  than in strict  conformity  with the
terms of this Section with the approval of the Board of Directors of the Company
and a Holder:  (i) with respect to any matter to cure any ambiguity  herein,  to
correct  this  subsection  (or any portion  thereof)  which may be  defective or
inconsistent  with the intended  4.9%  beneficial  ownership  limitation  herein
contained or to make changes or  supplements  necessary or desirable to properly
give effect to such 4.9% limitation;  and (ii) with respect to any other matter,
with the further  consent of the  holders of  majority  of the then  outstanding
shares of Common Stock. The Provisions of this Section may be waived by a Holder
upon ninety  (90) days prior  written  notice  from such Holder to the  Company,
including,  without  limitation,  a limited  waiver to  increase  the 4.9% limit
herein  contained to any other percentage  specified by Holder.  The limitations
contained in this Section shall apply to a successor  Holder of Preferred  Stock
if, and to the extent,  elected by such successor Holder  concurrently  with its
acquisition of such Preferred Stock,  such election to be promptly  confirmed in
writing  to the  Company  (provided  no  transfer  or series of  transfers  to a
successor  Holder or Holders shall be used by a Holder to evade the  limitations
contained herein).

     V. RESERVATION OF AUTHORIZED  SHARES OF COMMON STOCK;  LIMITATION ON NUMBER
OF CONVERSION SHARES

     A.  Reservation of Common Stock.  Subject to the provisions of this Article
V, 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 Preferred Stock and the exercise of the Warrants
a sufficient  number of shares of Common Stock to provide for the  conversion of
all outstanding Preferred Shares upon issuance of shares of Common Stock and the
exercise of all Warrants (the "Reserved  Amount").  The Reserved Amount shall be
allocated  among the Holders as provided in Section V(C). If the Reserved Amount
for any three (3)  consecutive  trading days (the last of such three (3) trading
days  being  the  "Authorization   Trigger  Date")  is  less  than  one  hundred
seventy-five  percent (175%) of the number of shares of Common Stock issuable on
such  trading  days  upon  conversion  of the  outstanding  Preferred  Stock and
exercise of the then outstanding Warrants (in each case without giving effect to
any  limitation  on  conversion  or exercise  thereof)  then the  Company  shall
immediately notify the Holders of such occurrence and shall immediately take all
necessary action  (including  stockholder  approval to authorize the issuance of
additional  shares  of Common  Stock) to  increase  the  Reserved  Amount to two
hundred  percent  (200%) of the number of shares of Common Stock  issuable  upon
conversion of the  outstanding  Preferred  Stock and exercise of all outstanding
Warrants (in each case, without giving effect to any limitation on conversion or
exercise thereof).

     B. Limitation on Number of Common Shares to be Issued.

     (i) Unless the  Stockholder  Approval (as defined  below) is obtained,  the
Company shall not be obligated to issue,  in the aggregate,  more than 2,745,000
shares of Common  Stock upon  conversion  of the  Preferred  Shares (the "Common
Share Limit"), such amount to be proportionally and equitably adjusted from time
to time in the event of stock splits,  stock  dividends,  combinations,  reverse
stock splits,  reclassifications,  capital  reorganizations  and similar  events
relating to the Common Stock). If the Stockholder Approval has not been obtained
at any time that the  Common  Share  Limit  with  respect to any Holder has been
reached,  Notices of  Conversion  by such Holder  shall be honored by payment to
such  Holder of cash in an amount  equal to the Closing Bid Price on the trading
day of delivery of the applicable Notice of Conversion  multiplied by the number
of shares  of Common  Stock  which  would be  issuable  in  satisfaction  of the
applicable  Notice of Conversion  (such  payment  being  referred to herein as a
"Cash Conversion").

     (ii) If the Stockholder Approval has been obtained at any time, the Company
shall have the right, subject to delivery of the notice required by Section V(E)
below,  to honor any Notices of Conversion  for shares of Common Stock in excess
of the Common  Share Limit by (a)  delivery of shares of Common  Stock or (b) by
Cash Conversion.

     C. Allocation of Reserved  Amount,  Common Share Limit. The Reserved Amount
and the  Common  Share  Limit  shall be  allocated  among  the  Initial  Holders
according  to the number of Preferred  Shares  issued to each such Holder on the
Closing Date. Any shares of Common Stock which were  initially  allocated to any
Holder  remaining after such Holder no longer owns any Preferred Shares shall be
allocated among the remaining Holders pro rata, based on the number of Preferred
Shares then held by such Holders.

                                       6

     D.  Share   Authorization.   The  Company   shall   solicit  by  proxy  the
authorization (the "Stockholder Approval") by the stockholders of the Company of
the  issuance of shares of Common Stock upon  conversion  of shares of Preferred
Stock pursuant to the terms hereof and the exercise of the Warrants  pursuant to
the terms  thereof  in the  aggregate  in excess of twenty  (20)  percent of the
outstanding  shares of Common Stock and to eliminate any prohibitions  under the
rules or  regulations of any stock  exchange,  interdealer  quotation  system or
other self-regulatory  organization with jurisdiction over the Company or any of
its  securities  on the  Company's  ability to issue  shares of Common  Stock in
excess of the Common Share Limit and use its commercially  reasonable efforts to
obtain the Stockholder  Approval no later than one hundred and twenty (120) days
following the date of the First Closing.

     E.  Obligation to Notify.  If the Company has not received the  Stockholder
Approval  by the date that is one hundred and twenty  (120) days  following  the
First Closing,  the Company shall, on or prior to such date, notify the Holders.
The  Company  shall  immediately  notify  the  Holders  if,  at  any  time,  the
Stockholder Approval is obtained. Following receipt of Stockholder Approval, the
Company shall have the right, by notice to all of the Holders not less than five
(5)  Business  Days prior to the first day of any  month,  to elect to honor all
Notices of Conversion  solely by Cash  Conversion (and not by delivery of Common
Stock1)  during  such month.  Each such  notice (a "Notice of Cash  Conversion")
shall be effective only with respect to the single month designated therein, and
shall specify,  as of the date of delivery of such notice,  the unissued portion
of the Common Share Limit of the Holder to whom such notice is being delivered.

                             VI. FAILURE TO CONVERT

     A.  Conversion  Defaults.  If, at any  time,  (x) the  Conversion  Date has
occurred  and the Company  fails for any reason to  deliver,  on or prior to the
second  Business Day  following the  expiration of the Delivery  Period for such
conversion  (said period of time being the  "Extended  Delivery  Period"),  such
number of shares of Common  Stock to which  such  Holder is  entitled  upon such
conversion,  or (y) the  Company  provides  notice  (including  by way of public
announcement)  to any Holder at any time of its intention not to issue shares of
Common Stock upon exercise by any Holder of its conversion  rights in accordance
with the terms of this  Certificate  of  Designation  (other than  because  such
issuance would exceed such Holder's  allocated  portion of the Reserved  Amount)
(each of (x) and (y) being a "Conversion  Default"),  then the Company shall pay
to the affected Holder, in the case of a Conversion  Default described in clause
(x) above, and to all Holders,  in the case of a Conversion Default described in
clause  (y) above,  an amount  equal to 1% of the Face  Amount of the  Preferred
Stock with respect to which the Conversion Default exists (which amount shall be
deemed to be the aggregate Face Amount of all outstanding Preferred Stock in the
case of a  Conversion  Default  described  in  clause  (y)  above)  for each day
thereafter  until  the Cure  Date.  "Cure  Date"  means  (i) with  respect  to a
Conversion  Default  described  in clause  (x) of its  definition,  the date the
Company  effects the conversion of the portion of the Preferred  Stock submitted
for conversion and (ii) with respect to a Conversion Default described in clause
(y) of its  definition,  the date the  Company  undertakes  in  writing to issue
Common Stock in satisfaction of all conversions of Preferred Stock in accordance
with the terms of this  Certificate  of  Designation  (provided that the Company
thereafter so performs such  obligations).  The Company shall  promptly  provide
each Holder with notice of the  occurrence of a Conversion  Default with respect
to any of the other Holders.  Notwithstanding  anything in this Section VI(A) or
anywhere else in this Agreement to the contrary,  no Conversion Default shall be
deemed to occur if, prior to expiration of the Delivery Period,  the Company has
made to the Holder the cash  payment  permitted  to be made  pursuant to Section
V(B) following issuance to such Holder of such Holder's allocated portion of the
Common Share Limit.

                                       7
<PAGE>

     B.  Conversion  Default  Payments.  The payments to which a Holder shall be
entitled pursuant to Section VI(A) are referred to herein as "Conversion Default
Payments."  Conversion  Default  Payments  shall be paid in cash  within two (2)
Business  Days of written  demand from a Holder.  Such payment  shall be made in
accordance with and be subject to the provisions of Section XIII(B).

     C.  Adjustments  to  Conversion   Price.  If  a  Holder  has  not  received
certificates  for all shares of Common Stock prior to the tenth (10th) day after
the expiration of the Delivery  Period with respect to a conversion of Preferred
Stock (or, if  applicable,  the cash payment  permitted  to be made  pursuant to
Section  V(B))  for any  reason  (other  than  as a  result  of such  conversion
exceeding  such  Holder's  pro rata  portion of the  Reserved  Amount)  then the
Conversion Price in respect of any shares of Preferred Stock held by such Holder
shall  thereafter be the lesser of (i) the  Conversion  Price on the  Conversion
Date  specified in the Notice of  Conversion  which  resulted in the  Conversion
Default  and (ii) the  lowest  Conversion  Price in  effect  during  the  period
beginning on, and including, such Conversion Date through but excluding the Cure
Date. If there shall occur a Conversion  Default of the type described in clause
(y) of Section VI(A),  then the Conversion  Price with respect to any conversion
thereafter shall be the lower of the Conversion Price and the lowest  Conversion
Price in effect at any time during the period  beginning on, and including,  the
date of the occurrence of such Conversion Default through but excluding the Cure
Date. The Conversion Price shall thereafter be subject to further  adjustment as
described in Article X.

                      VII. REDEMPTION DUE TO CERTAIN EVENTS

     A. Redemption Events. A "Redemption Event" means any one of the following:

     (i) the Common Stock  (including any of the shares of Common Stock issuable
upon  conversion  of the  Preferred  Stock or upon  exercise of the  Warrants or
required  from  time to time to be  reserved  pursuant  to this  Certificate  of
Designation or the Warrants) is suspended from trading on, or is not listed (and
authorized)  for  trading  on, the  Nasdaq,  the Nasdaq  Small Cap  Market,  the
American Stock Exchange,  or the New York Stock Exchange for an aggregate of ten
(10) trading days in any twelve (12) month period;

     (ii) the Company fails,  and any such failure  continues  uncured for seven
(7) Business Days after the Company has been notified  thereof in writing by the
Holder,  to remove any  restrictive  legend on any certificate for any shares of
Common Stock issued after the Effective  Date to the Holders upon  conversion of
the  Preferred  Stock or upon  exercise of the Warrants as and when  required by
this Certificate of Designation, the Warrants, the Securities Purchase Agreement
or the  Registration  Rights  Agreement dated as of April 24, 1998, by and among
the  Company  and  the  other  signatories  thereto  (the  "Registration  Rights
Agreement");

                                       8
<PAGE>

     (iii) the Company fails:  (x) to file the registration  statement  required
pursuant to Section 2.1 of the  Registration  Rights  Agreement on or before the
thirtieth (30th) day following Closing, and to cause the registration  statement
to be  declared  effective  on or before the one  hundred  fiftieth  (150th) day
following  Closing,  in a manner  which would allow the sale of all  Registrable
Securities (as defined in the Registration  Rights  Agreement);  or (y) to cause
the holders of Preferred Stock to be able to utilize such registration statement
for the  resale  of all of  their  Registrable  Securities  (as  defined  in the
Registration Rights Agreement),  unless the Company is using its best efforts to
remedy such  inability to utilize such  registration  statement,  subject to the
Company's  Board of Directors  having  determined  in their good faith  business
judgment by resolution  that the continued  effectiveness  of such  registration
statement  would  have a material  adverse  effect on the  Company's  ability to
consummate a financing,  acquisition,  merger or joint venture, in each case for
which substantive  discussions are underway,  the failure of which to consummate
would have a  material  adverse  effect on the  Company's  financial  condition,
results of operations or future prospects;  provided that in no event shall such
failure exist for a total of more than twenty (20) days in any twelve (12) month
period; or

     (iv) the Company  fails for any reason to (A) issue  shares of Common Stock
within ten (10)  Business  Days after the  expiration  of the Extended  Delivery
Period with respect to any conversion of Preferred  Stock, or (B) if applicable,
to make the cash payment to the extent  permitted to be made pursuant to Section
V(B)).

     (v) the Company  provides notice to any Holder,  including by way of public
announcement,  at any time, of its intention not to issue shares of Common Stock
to any Holder upon conversion in accordance  with the terms of this  Certificate
of Designation  (other than (i) because of unavailability of authorized  shares,
or (ii) because such issuance  would exceed such Holder's  allocated  portion of
the Common Share Limit,  for which  failures the Holders shall have the remedies
set forth elsewhere herein);

     (vi) the Company  breaches any material  covenant or other material term of
this Certificate of Designation, the Securities Purchase Agreement, the Warrants
or the Registration Rights Agreement,  the breach of which would have a material
adverse  effect on the Company or the rights of the Holder  with  respect to its
shares of Preferred Stock or the shares of Common Stock issuable upon conversion
of the  Preferred  Stock or upon  exercise  of the  Warrants,  and  such  breach
continues for a period of five (5) Business Days after written notice thereof to
the Company;

     (vii) any  representation or warranty of the Company made in any agreement,
statement or certificate given in writing in connection with the issuance of the
Preferred Stock (including,  without  limitation,  the Warrants,  the Securities
Purchase  Agreement or the  Registration  Rights  Agreement),  shall be false or
misleading in any material  respect when made and the breach of which has had or
could reasonably be expected to have a material adverse effect on the Company or
on the Holder with respect to its investment in the shares of Preferred Stock or
Warrants or the shares of Common Stock issuable upon conversion of the Preferred
Stock or upon exercise of the Warrants; or

     (viii) the Company  fails to increase  the  Reserved  Amount (A) within ten
(10) days  following an  Authorization  Trigger Date if such  increase  requires
solely  approval of the  Company's  Board of Directors or (B)  otherwise  within
sixty (60) days thereafter.

                                       9

     B.  Redemption By Holder.  Following the occurrence of a Redemption  Event,
each  Holder  shall have the right to elect at any time and from time to time by
delivery of a Redemption  Notice (as defined  herein) to the Company  while such
Redemption Event  continues,  to require the Company to purchase for cash for an
amount per share equal to the Redemption  Amount (as defined  herein) any or all
of the then  outstanding  shares of Preferred  Stock,  together with accrued and
unpaid dividends thereon and any Conversion Default Payments applicable thereto,
held  by such  Holder.  The  "Redemption  Amount"  with  respect  to a share  of
Preferred  Stock  means an  amount  equal to the  greater  of (i) 1.5  times the
aggregate  Face Amount of the Preferred  Shares for which a demand is being made
and (ii) an amount determined by the following formula:

                                 Face Amount x M
                               ------------------
                                       CP

     When: "CP" means the lowest Conversion Price during the period beginning on
the date of the Redemption Notice and ending on the date of redemption;  and "M"
means the highest  Closing Bid Price of the  Company's  Common  Stock during the
period beginning on the date of the Redemption  Notice and ending on the date of
the  redemption,  as reported in the  principal  securities  exchange or trading
market in which the Common Stock is traded.

     C. Optional Redemption by the Company.  Beginning upon the earlier to occur
of (i) the date that the Company  completes an  underwritten  public offering of
its Common Stock, or (ii) the first anniversary of the Closing Date, the Company
may, at its option, redeem for cash out of funds legally available therefor, all
of the outstanding Preferred Shares ("Optional Redemption") at a price per share
equal to the  greater of (i) 125% of the Face Amount of the  Preferred  Stock or
(ii) the product of (X) 125% of the Closing Bid Price of the Common Stock on the
trading day  preceding  the  Company's  Optional  Redemption  Notice (as defined
below) to the Preferred Shareholders,  multiplied by (Y) the number of shares of
Common Stock issuable upon conversion of the Preferred Stock being redeemed. The
Company may not deliver an Optional  Redemption Notice for a redemption for cash
unless  such  redemption  is with  respect  to all  then-outstanding  shares  of
Preferred  Stock and unless the Company had  ("Funding  Availability"):  (a) the
full  amount  to be paid  for the  Preferred  Shares  pursuant  to the  Optional
Redemption (the "Optional  Redemption Amount") in cash, available in a demand or
other immediately available account in a bank or similar financial  institution;
or (b)  immediately  available  credit  facilities,  in the full  amount  of the
Optional Redemption Amount in cash with a bank or similar financial  institution
(or binding  commitment  letters with respect thereto which  commitment  letters
shall be subject only to  commercially  reasonable  conditions  to closing as to
which the Company's Board of Directors has made a good faith business  judgement
will be fulfilled to permit consummation of the redemption hereunder); or (c) an
agreement with a standby underwriter or qualified buyer ready,  willing and able
to purchase  from the Company a sufficient  number of shares of stock to provide
proceeds  necessary  to redeem for the  Optional  Redemption  Amount in cash any
stock that is not converted  prior to  redemption;  or (d) a combination  of the
items set forth in the preceding clauses (A), (B) and (C),  aggregating the full
amount of the Optional Redemption Amount in cash. Any Optional Redemption Notice
delivered  in  accordance  with  the  immediately  preceding  sentence  shall be
accompanied by a statement  executed by a duly authorized officer of the Company


                                       10
<PAGE>

certifying that the Company has Funding  Availability  and by other  appropriate
documentation as evidence thereof. The Company shall provide each Holder with at
least 30 days' notice of any proposed optional  redemption pursuant this Section
VII(C) (an "Optional  Redemption  Notice").  Any optional redemption pursuant to
this Section  VII(C) shall be made ratably  among  Holders in  proportion to the
Face Amount of Preferred Stock then  outstanding  and held by such Holders.  The
Optional  Redemption Notice shall state the Face Amount of Preferred Stock to be
redeemed and the date on which the Optional  Redemption is to occur (which shall
not be less than  thirty  (30) or more than sixty (60)  Business  Days after the
date of delivery of the  Optional  Redemption  Notice) and shall be delivered by
the  Company to the  Holders  at the  address of such  Holder  appearing  on the
register of the Company for the Preferred Stock.

     Within seven (7)  business  days after the date of delivery of the Optional
Redemption Notice, each Holder shall provide the Company with instructions as to
the account to which payments associated with such Optional Redemption should be
deposited. On the date of the Optional Redemption,  provided for in the relevant
Optional  Redemption  Notice, (x) the Company will deliver the redemption amount
via wire transfer to the account designated by the Holders, (y) the Holders will
deliver the  certificates  relating to that number of shares of Preferred  Stock
being  redeemed,  duly executed for transfer or  accompanied  by executed  stock
powers, in either case,  transferring that number of shares to be redeemed. Upon
the occurrence of the wire transfer (or, in the absence of a Holder  designating
an account to which funds should be  transferred,  delivery of a certified check
in the amount due such Holder in connection with such Optional Redemption to the
address  of  such  Holder  appearing  on the  register  of the  Company  for the
Preferred Stock), that number of shares to be redeemed pursuant to such Optional
Redemption as represented by the previously  issued  certificates will be deemed
no  longer  outstanding.  Notwithstanding  anything  to  the  contrary  in  this
Certificate of Designation,  each Holder may continue to convert Preferred Stock
in  accordance  with the terms  hereof  until the date such  Preferred  Stock is
actually redeemed pursuant to an Optional Redemption.

     D. Redemption Payment Defaults.  If the Company fails to pay any Holder the
Redemption  Amount with respect to any share of Preferred  Stock, as provided in
this Article VII,  within five (5) Business Days of its receipt or delivery,  as
applicable, of a notice requiring such redemption, then each Holder (i) shall be
entitled to interest on the Redemption Amount at a floating per annum rate equal
to the lower of (x) eighteen  percent  (18%) and (y) the highest  interest  rate
permitted by  applicable  law from the date of the  Redemption  Notice until the
date of  redemption  hereunder,  payable in cash within two (2) Business Days of
written demand from a Holder. In the event the Company is not able to redeem all
of the shares of Preferred  Stock  subject to  Redemption  Notices,  the Company
shall redeem shares of Preferred  Stock from each Holder pro rata,  based on the
total  number of shares of Preferred  Stock  included in the  Redemption  Notice
relative  to the  total  number  of  shares  of  Preferred  Stock  in all of the
Redemption Notices.

                                       11
<PAGE>

     E.  Capital  Impairment.  In the  event  that any  section  of the New York
Business  Corporation Law ("NYBCL"),  would be violated by the redemption of any
shares of Preferred Stock that are otherwise  subject to redemption  pursuant to
this Article VII, the Company:  (i) will redeem the greatest number of shares of
Preferred  Stock possible  without  violation of said Section;  (ii) the Company
thereafter  shall use its best  efforts to take all  necessary  steps  permitted
pursuant to this  Certificate of Designation and the agreements  entered into in
connection  with the issuance of  Preferred  Stock  pursuant  hereto in order to
remedy its  capital  structure  in order to allow  further  redemptions  without
violation of said Section (and not take any actions inconsistent therewith); and
(iii) from time to time  thereafter  as promptly as possible  the Company  shall
redeem  shares of Preferred  Stock at the request of the Holders to the greatest
extent possible  without causing a violation of the NYBCL (such redemption to be
at the  greater of the  Redemption  Price in effect at the time of the  original
Redemption  Event giving rise to such violation and the  redemption  price which
would be applicable  for a Redemption  Event at the time of such later  election
under this clause (iii).  In such case, any Holder shall have the right,  at any
time and from time to time,  to require the  Company,  upon written  notice,  to
immediately  convert  (in  accordance  with the terms of  Article  IV all or any
portion of the  Redemption  Amount plus any interest or other charges which have
accrued  into shares of Common Stock on a dollar for dollar basis based upon the
most recently  reported  trading  price for the Common  Stock.  In the event the
Company is not able to redeem all the shares of the stock  subject to Redemption
Notices, the Company shall redeem shares of Preferred Stock from each Holder pro
rata,  based on the total number of shares of Preferred  Stock  included by such
Holder in the Redemption  Notice relative to the total number of Preferred Stock
in all Redemption  Notices.  In addition,  and  notwithstanding  anything to the
contrary  contained in this Section VII(E),  so long as the Company is prevented
from redeeming  shares of Preferred  Stock  pursuant to this Section VII.E,  the
Company  shall be (and  shall  be  deemed  to be) in  breach  of the  redemption
obligations  set forth in this  Section  VII(E) and each  Holder  shall have all
rights and remedies  under this  Certificate  of Designation or otherwise at law
for damages,  with respect to such breach.  Upon a Redemption Event described in
Section  VII(A)(iv),  to the extent that the Company  has not yet  obtained  the
Stockholder  Approval,  any Holder who has not had its Preferred Stock converted
in accordance with the terms of this Certificate of Designation may elect one or
both of the following: (i) require, with the consent of the Holders, the Company
to  terminate  the listing of its Common Stock on Nasdaq or the Nasdaq Small Cap
Market  and to cause  its  Common  Stock to be  listed  on the  over-the-counter
electronic  bulletin  board,  at the option of the requesting  Holder;  and (ii)
require  the Company to issue  shares of Common  Stock in  accordance  with such
holder's  Notice of  Conversion  at a conversion  price equal to the  Conversion
Price in effect on the date of the Holder's written notice to the Company of its
election to receive shares of Common Stock pursuant to this subparagraph (ii).

                                       12
<PAGE>

                  VIII.    RANK; PARTICIPATION

     A. Rank.  All  shares of the  Preferred  Stock  shall rank (i) prior to the
Common Stock;  (ii) prior to any class or series of capital stock of the Company
now outstanding or hereafter created (unless,  with the consent of a majority of
the Holders  obtained in  accordance  with  Article XII hereof,  such  hereafter
created  class or series of capital  stock  specifically,  by its  terms,  ranks
senior to or pari passu with the Preferred Stock) (collectively, with the Common
Stock,  "Junior  Securities");  and (iii) pari passu with any class or series of
capital stock of the Company  hereafter  created (with the consent of a majority
of the Holders  obtained in  accordance  with  Article XII hereof)  specifically
ranking,  by its terms,  on parity  with the  Preferred  Stock (the "Pari  Passu
Securities");  and (iv)  junior to any class or series of  capital  stock of the
Company  hereafter  created  (with the  consent  of a  majority  of the  Holders
obtained in accordance  with Article XII hereof)  specifically  ranking,  by its
terms, senior to the Preferred Stock (the "Senior Securities"),  in each case as
to  distribution  of assets upon  liquidation,  dissolution or winding up of the
Company, whether voluntary or involuntary.

     B.  Participation.  Subject to the rights of the  holders  (if any) of Pari
Passu Securities and Senior Securities,  the Holders shall, as such Holders,  be
entitled to such dividends paid and distributions  made to the holders of Common
Stock to the same  extent  as if such  Holders  had  converted  their  shares of
Preferred  Stock  into  Common  Stock  (without  regard  to any  limitations  on
conversion herein or elsewhere  contained) and had been issued such Common Stock
on the day before the record date for said  dividend or  distribution.  Payments
under the preceding  sentence  shall be made  concurrently  with the dividend or
distribution to the holders of Common Stock.

                           IX. LIQUIDATION PREFERENCE

     A.  Liquidation  of the Company.  If the Company shall commence a voluntary
case under the U.S. Federal bankruptcy laws or any other applicable  bankruptcy,
insolvency  or similar law, or consent to the entry of an order for relief in an
involuntary case under any law or to the appointment of a receiver,  liquidator,
assignee,  custodian,  trustee,  sequestrator (or other similar official) of the
Company or of any  substantial  part of its property,  or make an assignment for
the benefit of its creditors, or admit in writing its inability to pay its debts
generally  as they  become due, or if a decree or order for relief in respect of
the Company shall be entered by a court having  jurisdiction  in the premises in
an  involuntary  case  under  the  U.S.  Federal  bankruptcy  laws or any  other
applicable bankruptcy, insolvency or similar law resulting in the appointment of
a receiver,  liquidator,  assignee,  custodian,  trustee, sequestrator (or other
similar official) of the Company or of any substantial part of its property,  or
ordering the winding up or  liquidation  of its affairs,  and any such decree or
order  shall be  unstayed  and in effect for a period of sixty (60)  consecutive
days and, on account of any such event, the Company shall liquidate, dissolve or
wind up, or if the Company  shall  otherwise  liquidate,  dissolve or wind up (a
"Liquidation Event"), no distribution shall be made to the Holders of any shares
of capital stock of the Company (other than Senior Securities and, together with
the Holders of  Preferred  Stock the Pari Passu  Securities)  upon  liquidation,
dissolution  or winding up unless prior  thereto the Holders shall have received
the Liquidation  Preference (as herein defined) with respect to each share.  If,
upon the occurrence of a Liquidation  Event,  the assets and funds available for
distribution  among the Holders and  holders of Pari Passu  Securities  shall be
insufficient to permit the payment to such Holders of the  preferential  amounts
payable  thereon,  then the  entire  assets  and  funds of the  Company  legally
available for  distribution to the Preferred Stock and the Pari Passu Securities
shall be  distributed  ratably among such shares in proportion to the ratio that
the  Liquidation  Preference  payable on each such share bears to the  aggregate
Liquidation Preference payable on all such shares.

                                       13
<PAGE>

     B.  Certain  Acts Not a  Liquidation.  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 entity 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.

     C. Definition of Liquidation Preference.  The "Liquidation Preference" with
respect to a share of  Preferred  Stock means an amount equal to the Face Amount
thereof  plus any other  amounts  that may be due from the Company  with respect
thereto  pursuant to this  Certificate of Designation  through the date of final
distribution.  The  Liquidation  Preference  with  respect  to  any  Pari  Passu
Securities  shall be as set forth in the  Certificate  of  Designation  filed in
respect thereof.

           X. ADJUSTMENTS TO THE CONVERSION PRICE; CERTAIN PROTECTIONS

     The Conversion Price shall, in order to accomplish the results contemplated
in this  Certificate of Designation,  be subject to adjustment from time to time
as follows:

     A.  Stock  Splits,  Stock  Dividends,  Etc.  If at any time on or after the
Closing Date, the number of outstanding shares of Common Stock is increased by a
stock split,  stock  dividend,  combination,  reclassification  or other similar
event,  the number of shares of Common Stock  issuable  upon  conversion  of the
Preferred  Stock  shall  be  proportionately  increased,  or if  the  number  of
outstanding  shares of Common  Stock is  decreased  by a  reverse  stock  split,
combination or reclassification of shares, or other similar event, the number of
shares of Common Stock issuable upon  conversion of the Preferred Stock shall be
proportionately  reduced.  In such event, the Company shall notify the Company's
transfer agent of such change on or before the effective date thereof.

     B. Certain Public Announcements.  In the event that (i) the Company makes a
public  announcement  that it  intends  to  consolidate  or merge with any other
entity  (other than a merger in which the Company is the surviving or continuing
entity and its capital stock is unchanged and there is no distribution  thereof)
or to sell or transfer all or substantially  all of the assets of the Company or
(ii) any person,  group or entity (including the Company)  publicly  announces a
tender  offer in  connection  with which such  person,  group or entity seeks to
purchase 50% or more of the Common Stock (the date of the announcement  referred
to in clause (i) or (ii) of this  paragraph  is  hereinafter  referred to as the
"Announcement  Date"),  then the  Conversion  Price  shall,  effective  upon the
Announcement Date and continuing through the consummation of the proposed tender
offer or transaction or the Abandonment Date (as defined below), be equal to the
lesser of (x) the Conversion  Price calculated as provided in Article IV the (y)
the Conversion  Price which would have been applicable for Conversion  occurring
on the Announcement  Date. From and after the Abandonment  Date, as the case may
be, the  Conversion  Price shall be  determined  as set forth in Article IV. The
"Abandonment  Date" means with  respect to any  proposed  transaction  or tender
offer for which a public announcement as contemplated by this paragraph has been
made,  the date  which is seven (7)  trading  days after the date upon which the
Company (in the case of clause (i) above) or the person, group or entity (in the
case of clause (ii) above) publicly  announces the termination or abandonment of
the proposed  transaction  or tender offer which causes this paragraph to become
operative.

     C. Major Transactions.  If the Company shall consolidate with or merge into
any corporation or reclassify its outstanding shares of Common Stock (other than
by way of subdivision or reduction of such shares) (each a "Major Transaction"),
then each Holder  shall  thereafter  be entitled  to receive  consideration,  in
exchange for each share of Preferred  Stock held by it, equal to the greater of,
as determined in the sole discretion of such Holder: (i) the number of shares of
stock or securities or property of the Company,  or of the entity resulting from
such Major  Transaction  (the  "Major  Transaction  Consideration"),  to which a
Holder of the number of shares of Common Stock delivered upon conversion of such
shares of Preferred  Stock would have been entitled upon such Major  Transaction
had  the  Holder's  Preferred  Shares  been  converted  (without  regard  to any
limitations  on conversion  herein  contained)  on the trading date  immediately
preceding the public  announcement  of the  transaction  resulting in such Major
Transaction  and had such Common Stock been issued and  outstanding and had such
Holder been the holder of record of such Common  Stock at the time of such Major
Transaction,  and the Company shall make lawful provision therefore as a part of
such consolidation, merger or reclassification; and (ii) 125% of the Face Amount
of such  shares of  Preferred  Stock in cash.  No sooner  than ten (10) days nor
later than five (5) days prior to the consummation of the Major Transaction, but
not prior to the public  announcement  of such Major  Transaction,  the  Company
shall deliver  written notice  ("Notice of Major  Transaction")  to each Holder,
which Notice of Major Transaction shall be deemed to have been delivered one (1)
Business Day after the Company's sending such notice by telecopy  (provided that
the Company sends a confirming  copy of such notice on the same day by overnight
courier). Such Notice of Major Transaction shall indicate the amount and type of
the Major Transaction Consideration which such Holder would receive under clause
(i) of this  Section  X(C).  If the  Major  Transaction  Consideration  does not
consist  entirely  of United  States  dollars,  such Holder may elect to receive
United States dollars in an amount equal to the value, determined by a reputable
accounting  firm  selected by the Company  that is  reasonably  acceptable  to a
majority of the Holders of the Major  Transaction  Consideration  in lieu of the
Major Transaction Consideration which does not consist entirely of United States
Dollars,  by delivering  notice of such election to the Company  within five (5)
days of the Holder's receipt of the Notice of Major Transaction.

     D.  Issuance of Other  Securities.  If, at any time after the First Closing
the  Company  shall  issue  any  securities   which  are  convertible   into  or
exchangeable  for  Common  Stock  ("Convertible  Securities")  either  (i)  at a
conversion  or exchange  rate based on a discount  from the market  price of the
Common  Stock  at the  time of  conversion  or  exercise  or  (ii)  with a fixed
conversion  or  exercise  price less than the  Conversion  Price,  then,  at the
Holder's option:  (x) in the case of clause (i), the Conversion Price in respect
of any  conversion of Preferred  Stock after such  issuance  shall be calculated
utilizing the greatest discount  applicable to any such Convertible  Securities,
to the extent such calculation would result in a lower Conversion Price; and (y)
in the case of clause (ii), the Conversion  Price will be reduced to such lesser
conversion  or exercise  price,  to the extent that this would result in a lower
Conversion Price.

                                       15
<PAGE>

     E. Adjustment Due to  Distribution.  If at any time after the Closing Date,
the Company shall declare or make any  distribution  of its assets (or rights to
acquire  its  assets)  to  holders  of  Common  Stock as a  partial  liquidating
dividend,  by way of return of capital or otherwise  (including  any dividend or
distribution  to the  Company's  stockholders  in cash or shares  (or  rights to
acquire  shares)  of  capital  stock  of a  subsidiary  (i.e.  a  spin-off))  (a
"Distribution"),  then the Conversion Price shall be equitably  adjusted to take
account of such distribution.

     F.  Purchase  Rights.  If at any time after the Closing  Date,  the Company
issues  any  Convertible  Securities  or rights  to  purchase  stock,  warrants,
securities  or other  property  (the  "Purchase  Rights") pro rata to the record
holders of any class of Common  Stock,  then the  Holders  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  Stock  (without  regard to any  limitations on conversion or exercise
herein or elsewhere contained)  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.

     G.  Notice  of  Adjustments.  Upon the  occurrence  of each  adjustment  or
readjustment of the Conversion Price pursuant to this Article X, the Company, at
its expense,  shall promptly compute such adjustment or readjustment and prepare
and  furnish to each  Holder a  certificate  setting  forth such  adjustment  or
readjustment  and  showing in detail the facts  upon  which such  adjustment  or
readjustment is based.  The Company shall,  upon the written request at any time
of any Holder,  furnish to such Holder a like certificate setting forth (i) such
adjustment or readjustment,  (ii) the Conversion Price at the time in effect and
(iii) the  number of shares of Common  Stock and the  amount,  if any,  of other
securities or property which at the time would be received upon  conversion of a
share of Preferred Stock.

                                XI. VOTING RIGHTS

     No holder of the  Preferred  Stock  shall be entitled to vote on any matter
submitted to the shareholders of the Company for their vote, waiver,  release or
other action, except as may be otherwise expressly required by law.

                           XII. PROTECTION PROVISIONS

     So long as any  Preferred  Shares are  outstanding,  the Company shall not,
without first obtaining the approval of a majority of the Holders:  (a) alter or
change the rights,  preferences or privileges of the Preferred  Stock; (b) alter
or change the rights,  preferences  or  privileges  of any capital  stock of the
Company so as to affect  adversely  the Preferred  Stock;  (c) create any Senior
Securities;  (d) create any Pari Passu  Securities;  (e) increase the authorized
number of shares of  Preferred  Stock;  (f)  redeem or  declare  or pay any cash
dividend or  distribution on any Junior  Securities,  or (g) do any act or thing
not authorized or  contemplated by this  Certificate of Designation  which would
result in any taxation with respect to the 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,  (or otherwise
suffer to exist any such taxation as a result thereof).

                               XIII. MISCELLANEOUS

     A. Lost or Stolen Certificates. Upon receipt by the Company of (i) evidence
of  the  loss,   theft,   destruction  or  mutilation  of  any  Preferred  Stock
Certificate(s)  and  (ii) (y) in the case of  loss,  theft  or  destruction,  of
indemnity  reasonably  satisfactory  to the  Company,  or (z)  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.  However,  the  Company  shall not be
obligated to reissue such lost, stolen,  destroyed or mutilated  Preferred Stock
Certificate(s) if the Holder  contemporaneously  requests the Company to convert
such Preferred Stock.

     B. Statements of Available Shares. Upon request,  the Company shall deliver
to each Holder a written report  notifying the Holders of any  occurrence  which
prohibits the Company from issuing  Common Stock upon any such  conversion.  The
report  shall also  specify (i) the total  number of shares of  Preferred  Stock
outstanding  as of the date of the  request,  (ii) the total number of shares of
Common Stock issued upon all  conversions of Preferred Stock through the date of
the request, (iii) the total number of shares of Common Stock which are reserved
for  issuance  upon  conversion  of the  Preferred  Stock  as of the date of the
request,  and (iv) the  total  number  of  shares  of  Common  Stock  which  may
thereafter  be issued by the Company  upon  conversion  of the  Preferred  Stock
before the Company would exceed the Common Share Limit and Reserved Amount.  The
Company  shall,  within five (5) days after delivery to the Company of a written
request by any Holder,  provide all of the information enumerated in clauses (i)
- - (v) of this  Section  XIII(B)  and,  at the  request of a Holder,  make public
disclosure thereof.

     C. Payment of Cash; Defaults.  Whenever the Company is required to make any
cash payment to a Holder under this  Certificate of Designation (as a Conversion
Default  Payment,  Redemption  Amount or otherwise),  such cash payment shall be
made to the  Holder by the  method  (by  certified  or  cashier's  check or wire
transfer of immediately available funds) elected by such Holder. If such payment
is not delivered  when due such Holder shall  thereafter be entitled to interest
on the unpaid  amount  until such  amount is paid in full to the Holder at a per
annum rate equal to the lower of (x) eighteen  percent (18%) and (y) the highest
interest rate permitted by applicable law.

                                       17
<PAGE>

     D. Conversion of Default Amounts. In addition, and notwithstanding anything
to the contrary contained in this Certificate,  a Holder may elect in writing to
convert all or any portion of accrued Default Amounts, at any time and from time
to time, into Common Stock at the lowest  Conversion  Price in effect during the
period  beginning on the date of the default with  respect  thereto  through the
cure date for such default.  In the event that a Holder elects to convert all or
any portion of the Default Amounts into Common Stock, the Holder shall so notify
the Company on a Notice of  Conversion  of such  portion of the Default  Amounts
which such holder elects to so convert and such  conversion  shall  otherwise be
effected  in  accordance  with the  provisions  of, and  subject to  limitations
contained in, Article IV.

     E. Remedies, Characterizations,  Other Obligations, Breaches and Injunctive
Relief.  The  remedies  provided in this  Certificate  of  Designation  shall be
cumulative  and  in  addition  to  all  other  remedies   available  under  this
Certificate of Designation,  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 a Holder's  right to pursue  actual  damages for any
failure  by the  Company  to  comply  with  the  terms  of this  Certificate  of
Designation (including,  without limitation,  damages incurred to effect "cover"
purchase of shares of Common Stock  anticipated to be received upon a conversion
hereunder  and not  received  in  accordance  with the  terms  hereof).  Company
covenants to each Holder that there shall be no characterization concerning this
instrument other than as expressly provided herein; provided,  however, that the
Company  shall  be  entitled  to  prepare   summaries  of  this  Certificate  of
Designation  for purposes of complying  with its disclosure  obligations  and in
connection  with bona fide disputes as to the  operations  of the  provisions of
this  Certificate of Designation.  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  hereof 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 Preferred
Stock 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  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.

     F. Specific Shall Not Limit General;  References to "Preferred  Stock".  No
specific  provision  contained in this Certificate of Designation shall limit or
modify  any  more  general  provision  contained  herein.  This  Certificate  of
Designation shall be deemed to be jointly drafted by the Company and the Holders
and shall not be  construed  against any person as the  drafter.  Any  reference
herein  to  Preferred  Shares,  Preferred  Stock  or an  unspecified  amount  of
Preferred  Shares  or  Preferred  Stock  shall be  deemed  to  include,  without
limitation,  all shares of Preferred Stock issued or then issuable as a dividend
or otherwise in  satisfaction  of any  obligation of the Company with respect to
any Preferred Stock issued on the date hereof.

     G. Failure or Indulgency  Not Waiver.  No failure or delay on the part of a
Holder in the exercise of any power, right or privilege  hereunder shall operate
as a waiver thereof, not 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.
