         The  information  contained in Item 3 to the Schedule is hereby amended
and restated to read in its entirety as follows:

               On December 7, 1995,  Aries  Domestic  used its general  funds to
               extend a bridge  loan (a  "Bridge  Loan")  to the  Issuer  in the
               amount of $125,000 for which it received  62,500 Class A Warrants
               (the  "Class A  Warrants")  and the Aries  Trust used its general
               funds to  extend a Bridge  Loan to the  Issuer  in the  amount of
               $75,000 for which it received  37,500 Class A  Warrants./1/  Each
               Class A Warrant  entitles its holder to acquire (a) one (1) share
               of common  stock of the Issuer  par value  $.00025  (the  "Common
               Stock") and (b) one (1) Class B Warrant  (the "Class B Warrants")
               to acquire  one (1) share of Common  Stock.  The Class A Warrants
               are presently  exercisable at $4.42 per share of Common Stock and
               the Class B Warrants will be exercisable,  when issued,  at $5.89
               per share of Common Stock  (subject to  adjustment).  The Class A
               Warrants and the Class B Warrants will expire on May 16, 2001. On
               July 21, 1997,  Aries Domestic used its general funds to extend a
               line of credit (a "Line of  Credit")  to the Issuer in the amount
               of  $154,000  for which Aries  Domestic  received  warrants  (the
               "Original  LOC  Warrants")  to purchase  35,000  shares of Common
               Stock of the Issuer and the Aries Trust used its general funds to

               for which the Aries  Trust  received  Original  LOC  Warrants  to
               purchase  65,000  shares of Common  Stock of the  Issuer./2/  The
               Original LOC Warrants are presently exercisable at $.99 per share
               of Common Stock and will expire on July 21, 2002. In addition, on
               August 29, 1997, in a private placement (the "Private Placement")
               of the Issuer's securities, Aries Domestic used its general funds
               to purchase 3.4 units the "Units" for an aggregate purchase price
               of  $340,000,  with each  Unit  consisting  of  10,000  shares of
               Preferred  Stock (the "Preferred  Stock").  The 3.4 Units held by
               Aries Domestic are presently  convertible into 380,800/3/  shares
               of Common  Stock of the Issuer.  The Aries Trust used its general
               funds to  purchase  6.6  Units in the  Private  Placement  for an
               aggregate  purchase  price  of  $660,000,  which  6.6  Units  are
               presently  convertible into 739,200/4/  shares of Common Stock of

               (b)  Subject  to the  performance  by the  Company  of all of its
obligations  to be performed  under this Agreement and to the  completeness  and
accuracy of all  representations and warranties of the Company contained in this
Agreement,  the Placement Agent hereby accepts such agency and agrees to use its
best efforts to assist the Company in finding qualified  subscribers pursuant to
the Offering  described in the Offering  Documents.  It is  understood  that the
Placement  Agent has no  commitment  to sell the Units.  The  Placement  Agent's
agency hereunder is not terminable by the Company except upon termination of the
Offering Period.

               (c) The Placement Agent may engage other persons,  selected by it
in its  discretion,  that are members of the National  Association of Securities
Dealers,  Inc.  ("NASD") or who are located  outside the United  States and that

referred  to as a  "Selected  Dealer")  and the  Placement  Agent may allow such
persons  such part of the  compensation  and payment of expenses  payable to the
Placement Agent hereunder as the Placement Agent shall determine.

               (d)  Subscriptions  for Units shall be evidenced by the execution

Closing is held, all  subscription  funds received shall be held as described in
the Subscription  Agreement.  The Placement Agent shall not have any independent
obligation to verify the accuracy or completeness  of any information  contained
in any Subscription  Agreement or the  authenticity,  sufficiency or validity of
any check delivered by any prospective  investor in payment for Units, nor shall
the Placement Agent incur any liability with respect to any such check.

          2.   REPRESENTATIONS  AND  WARRANTIES  OF  THE  COMPANY.  The  Company
represents,  warrants and  covenants to the  Placement  Agent and each  Selected

Regulation  D  promulgated  thereunder  and with the  requirements  of all other

writing by the Placement Agent to the Company  specifically for inclusion in the
Offering  Documents.  If at any time prior to the  completion of the Offering or

it might become necessary to amend or supplement the Offering  Documents so that
they do not include any untrue  statement of any material  fact or omit to state
any material  fact  necessary in order to make the  statements  therein,  in the
light of the  circumstances  then  existing,  not  misleading,  the Company will
promptly  notify the Placement Agent and will supply the Placement Agent (or the

supplements correcting such statement or omission. The Company will also provide
the  Placement  Agent for  delivery to all  offerees  and  purchasers  and their
representatives,  if any, any information,  documents and instruments  which the
Placement  Agent and the Company's  counsel  reasonably deem necessary to comply

the business, financial condition or prospects of the Company.

capital  stock of the  Company  prior to the  consummation  of the  transactions

it and all such returns are true and correct in all material  respects.  Each of

the  Subsidiaries  is in compliance with all federal,  state,  local or foreign,
laws, ordinances,  regulations and orders applicable to its respective business,

Company's  and the  Subsidiary's  Licenses  are in full  force and effect and no
violations are or have been recorded in respect of any License and no proceeding

requisite corporate action by the Company and when delivered, constitute or will
constitute the legal, valid and binding obligations of the Company,  enforceable
in accordance  with their  respective  terms,  subject to the  availability  and

Offering  Documents may be limited by federal or state securities laws or public
policy.  Subject  to  the  filing  prior  to the  Initial  Closing  Date  of the
Certificate of Designation,  the Company has full power and lawful  authority to
authorize,  issue and sell the Units to be sold to the Purchasers. No consent is
required  by the Company or either of the  Subsidiaries  from any third party to
perform  any of its  obligations  under this  Agreement  or any of the  Offering
Documents.

               (o) EXEMPTION FROM REGISTRATION. Assuming (i) the accuracy of the
information   provided  by  the  respective   Purchasers  in  the   Subscription
Agreements, and (ii) the timely filing of a Form D by the Company, the offer and
sale of the Units and the  granting of the  Placement  Warrants  pursuant to the
terms of this  Agreement are exempt from the  registration  requirements  of the
Securities  Act  and the  rules  and  regulations  promulgated  thereunder  (the
"Regulations").  The  Company  is not  disqualified  from  the  exemption  under
Regulation D by virtue of the disqualifications contained in Rule 505(b)(2)(iii)
or Rule 507  promulgated  thereunder  and the  securities  underlying the Units.
There  exist  no fact or set of facts  which  might  cause  the  Offering  to be
integrated with any other offering of the Company's securities.

               (p) REGISTRATION RIGHTS. Except as set forth in the Term Sheet or
Section 5 of the Subscription  Agreements,  no person has any right to cause the
Company to effect the registration under the Securities Act of any securities of
the Company.

               (q)  BROKERS.  Neither  the  Company  nor  any of  its  officers,
directors,  employees  or  stockholders  has  employed  any  broker or finder in
connection with the  transactions  contemplated by this Agreement other than the
Placement Agent.

               (r) TITLE TO PREFERRED STOCK. When certificates  representing the
Preferred  Stock shall have been duly  delivered to the  Purchasers  and payment
shall have been made for the Units,  the several  Purchasers shall have good and
valid title to the Preferred  Stock, and upon conversion of such Preferred Stock
(including  the  Preferred   Stock  issuable  upon  exercise  of  the  Placement
Warrants),  subject  to the filing of an amended  Certificate  of  Incorporation
increasing  the number of  authorized  shares of the  Company's  Common Stock as
contemplated  by the Term  Sheet,  will have good and valid  title to the Common
Stock issuable upon such conversion  (the  "Conversion  Shares"),  in each case,
free and clear of all liens, encumbrances and adverse claims, whatsoever (except
as arising from applicable Federal and state securities laws), and the Company

shall have paid all taxes, if any, in respect of the original  issuance thereof.
When  certificates  representing  the  Placement  Warrants  shall have been duly
delivered to the Placement  Agent,  the Placement  Agent or its designees  shall
have good and valid title to the Placement  Warrants,  and upon exercise of such
Placement  Warrants,  will  have  good and valid  title to the  Preferred  Stock
issuable upon such exercise, and upon conversion of the Preferred Stock issuable
upon exercise of such Placement Warrants,  will have good and valid title to the
Common Stock into which such Preferred  Stock is converted,  in each case,  free
and clear of all liens,  encumbrances and adverse claims,  whatsoever (except as
arising from  applicable  Federal and state  securities  laws),  and the Company
shall have paid all taxes, if any, in respect of the original issuance thereof.

               (s)  NON-AFFILIATED  DIRECTORS.  The Company's Board of Directors
has not less than two directors who are independent from, and unaffiliated with,
management of the Company.

               (t) ACCURACY OF REPORTS.  All reports required to be filed by the
Company and the  Subsidiaries  under the Securities and Exchange Act of 1934, as
amended (the "Exchange Act"), have been duly filed with the Commission, complied
at the time of filing in all material  respects with the  requirements  of their
respective  forms and,  except to the extent  updated or  superseded by the Term
Sheet or any  subsequently  filed  report,  were  complete  and  correct  in all
material  respects as of the dates at which the information  was furnished,  and
contained  (as of such dates) no untrue  statement of a material fact or omitted
to state a material  fact  necessary in order to make the  statements  contained
therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading.

               (u) AUTHORIZED SHARES. The Company shall (i) use its best efforts
to increase the authorized shares of Common Stock of the Company to a minimum of
40,000,000  and in any case a number of shares  sufficient  for the  purpose  of
conversion  of all the  Preferred  Stock  sold in or  related  to this  Offering
including  without  limitation,  (x) the Common Stock  underlying  the Placement
Warrants and (y) the Common Stock  underlying the Preferred Stock resulting from
dividends  paid  on  the  Preferred  Stock  (or  such  other  amounts  as may be
authorized by the Board of Directors) within 90 days following the Final Closing
Date  but in any  event  shall  effect  such  increase  no  later  than 180 days
following the Final Closing Date and (ii) at all times after the date upon which
such  Common  Stock  is  authorized,  reserve  and  keep  available  out  of its
authorized  but  unissued  shares of Common  Stock  solely  for the  purpose  of
effecting the conversion of the shares of Preferred Stock, such number of shares
of  Common  Stock  as  shall  from  time to time be  sufficient  to  effect  the
conversion  of all  outstanding  shares of the Preferred  Stock.  If at any time
Placement  Agent elects to convert any of its shares of Preferred  Stock and the
Company does not have  authorized and reserved for issuance a sufficient  number

outstanding  shares  of  Preferred  Stock,  then the  Placement  Agent  shall be
entitled to receive upon  conversion of its Preferred  Stock only that number of
shares of Common Stock as equals the  Placement  Agent's Pro Rata  Percentage of
the number of shares of Common Stock  authorized  and reserved for issuance upon
conversion of Preferred Stock.

         For purposes of the previous sentence,  the Placement Agent's "Pro Rata
Percentage"  on any date equals the number of shares of Preferred  Stock held of
record by the  Placement  Agent on such date  divided by the number of shares of
Preferred Stock held of record by all holders of Preferred Stock on such date.

         In addition to the  foregoing,  if after 180 days  following  the Final
Closing Date the Company has failed to authorize and reserve a sufficient number
of shares of Common Stock to permit conversion in full of all outstanding shares
of Preferred Stock, the Company shall, for no additional consideration, issue to
the Placement Agent  additional  shares of Preferred Stock equal to 0.25% of the
shares of Preferred Stock then held by Placement  Agent,  exclusive of shares of
Preferred  Stock issued  pursuant to this Section 2(u), for each day the Company
lacks  sufficient  authorized  and  reserved  shares of  Common  Stock to permit
conversion in full of all outstanding shares of Preferred Stock.

          3.   CLOSING; PLACEMENT AND FEES.

               (a)  CLOSING.  Provided  that the  Placement  Agent has  received
subscriptions for the Minimum Offering amount,  the Placement Agent may conduct,
in its sole  discretion,  closings  (the date of each a  "Closing  Date") at the
offices of the Placement  Agent,  787 Seventh Avenue,  New York, New York, until
the Final Closing  Date. On each Closing Date,  payment for the Units issued and
sold by the Company shall be made to the Company in immediately  available funds
against delivery of certificates  evidencing the Preferred Stock comprising such
Units.

               (b) CONDITIONS TO PLACEMENT AGENT'S OBLIGATIONS.  The obligations

                    (i)  DUE  QUALIFICATION  OR  EXEMPTION.   (A)  The  Offering

qualification  under the  securities  laws of the  several  states  pursuant  to
paragraph 3(c) below not later than the Closing Date,  subject to any filings to
be made  thereafter,  and (B) at the Closing Date, no stop order  suspending the

                    (ii)  NO  MATERIAL  MISSTATEMENTS.   Neither  the  Blue  Sky
qualification  materials,  the Offering  Documents,  nor the Term Sheet, nor any
supplement  thereto,  will  contain an untrue  statement  of a fact which in the
opinion of the Placement  Agent is material,  or omit to state a fact,  which in
the  opinion of the  Placement  Agent is  material  and is required to be stated
therein,  or is, in the opinion of the  Placement  Agent,  necessary to make the
statements  therein,  in light of the circumstances  under which they were made,
not misleading;

                    (iii)  COMPLIANCE  WITH  AGREEMENTS.  The Company  will have
complied with all  agreements  and  satisfied  all  conditions on its part to be
performed or satisfied  hereunder  and under the  Subscription  Agreements at or
prior to each Closing;

                    (iv)  CORPORATE  ACTION.  The  Company  will have  taken all
corporate  action  necessary  to  permit  the  valid  execution,   delivery  and
performance  of  the  Offering  Documents  by  the  Company,  including  without
limitation,  obtaining the approval of the Company's  board of directors for the
execution  and delivery of the Offering  Documents,  the increase in  authorized
shares of Common Stock of the  Company,  the  performance  by the Company of its
obligations hereunder and the Offering contemplated hereby;

                    (v) OPINIONS OF COUNSEL TO THE COMPANY.  The Placement Agent
shall receive the opinion of Buchanan Ingersoll, counsel to the Company (stating
that each of the  Purchasers  may rely thereon as though  addressed  directly to
such  Purchaser),  dated as of each Closing  Date,  substantially  to the effect
that:

                         (A) Each of the  Company and the  Subsidiaries  is duly
incorporated  and is validly  existing and in corporate  good standing under the
laws of its jurisdiction of incorporation, has all requisite corporate power and
authority  necessary to own or hold its  properties  and conduct its business as
described in the Term Sheet and is duly  qualified or licensed to do business as
a foreign  corporation and is in good standing in each jurisdiction in which the
nature of the  business  conducted,  or as proposed to be  conducted in the Term
Sheet,  by it or the  properties  owned,  leased or operated  by it,  makes such
qualification or licensing necessary and where the failure to be so qualified or
licensed would have a material  adverse effect upon the business,  prospects and
financial  condition of the Company.  To such counsel's  knowledge,  except with
respect to the  Subsidiaries,  the Company does not own, directly or indirectly,
any capital  stock or other  equity  ownership or  proprietary  interests in any
other  corporation,  association,  trust,  partnership,  joint  venture or other
entity;

                         (B) the execution,  delivery and performance of each of
the Offering Documents to which the Company is a signatory,  and the issuance of
(I) the Preferred  Stock and the Placement  Warrants,  (II) the Preferred  Stock
issuable upon exercise of the Placement Warrants and (III) the Conversion Shares
(including the Conversion  Shares  underlying the Preferred  Stock issuable upon
exercise of the Placement Warrants),  have been duly authorized,  subject to the
filing of an  amended  Certificate  of  Incorporation  increasing  the number of
authorized  shares of the  Company's  Common Stock as  contemplated  by the Term
Sheet, by all necessary corporate action on the part of the Company. Each of the
Offering  Documents to which the Company is a signatory  has been duly  executed
and  delivered  by the  Company  and  constitutes  a legal,  valid  and  binding
obligation of the Company  enforceable in accordance  with its terms,  except as
such  enforceability  may  be  limited  by  applicable  bankruptcy,  insolvency,
reorganization, moratorium, fraudulent conveyance, receivership or other laws of
general  application  relating to or  affecting  generally  the  enforcement  of
creditors'  rights and the  application  of equitable  principles in any action,
legal or  equitable,  and except as rights to indemnity or  contribution  may be
limited by applicable law;

                         (C) the  authorized,  issued  and  outstanding  capital
stock  of the  Company  as of the  date  hereof  (before  giving  effect  to the
transactions  contemplated by this Agreement) is as set forth in the Term Sheet.
To  such  counsel's  knowledge,  there  are no  outstanding  warrants,  options,
agreements,  convertible  securities,  preemptive  rights  or other  commitments
pursuant to which the Company is, or may become,  obligated  to issue any shares
of its capital stock or other  securities of the Company other than as set forth
in the Term Sheet. All of the issued shares of capital stock of the Company have
been duly and validly  authorized and issued,  are fully paid and  nonassessable
and to the best of such counsel's  knowledge,  have not been issued in violation
of the preemptive rights of any security holder;

                         (D)  assuming  (x)  the  accuracy  of  the  information
provided by the Subscribers in the Subscription Documents, (y) the timely filing
with the Commission and any applicable  state  securities  authority of a Form D
and  amendments  thereto  containing  accurate  and  complete  information,  the
issuance and sale of the Units is exempt from registration  under the Securities
Act and Rule 506 of Regulation D promulgated thereunder;

                         (E) neither the  execution and delivery of the Offering
Documents nor compliance with the terms hereof or thereof,  nor the consummation
of the  transactions  herein or therein  contemplated,  has, nor will,  conflict
with,  result in a breach of, or constitute a default under the  Certificate  of
Incorporation  or By-laws of the Company or either of the  Subsidiaries,  or any
material  contract,  instrument  or document  known to such  counsel,  after due
inquiry,  to which the Company or either of the  Subsidiaries  is a party, or by
which it or any of its properties is bound

or, to the best  knowledge  of such  counsel,  violate any  applicable  order or
decree of any governmental  agency or court having jurisdiction over the Company
or either of the Subsidiaries or any of its properties or business;

                         (F)  except as  disclosed  in the Term  Sheet,  to such
counsel's best knowledge, there are no claims, actions, suits, investigations or
proceedings  before  or by any  arbitrator,  court,  governmental  authority  or
instrumentality  pending  or  threatened  against  the  Company or either of the
Subsidiaries.  Except  as  disclosed  in  the  Term  Sheet,  to  such  counsel's
knowledge,  neither  the Company  nor either of the  Subsidiaries  is a party or
subject to the provisions of any order, writ, injunction,  judgment or decree of
any court or government agency or instrumentality;

                         (G) upon the issuance of the Units, the Preferred Stock
(including the shares of Preferred Stock issuable upon exercise of the Placement
Warrants),  the Placement  Warrants and the  Conversion  Shares,  subject to the
filing of an  amended  Certificate  of  Incorporation  increasing  the number of
authorized  shares of the  Company's  Common Stock as  contemplated  by the Term
Sheet,  (including the Conversion Shares underlying the Preferred Stock issuable
upon exercise of Placement  Warrants),  each of the  purchasers or the Placement
Agent and its designees, as the case may be, shall acquire such securities, free
and clear of all pledges, liens, claims, encumbrances, preemptive rights, rights
of first offer or right of first refusal and restrictions  known to such counsel
after  due  inquiry,  except  for the  transfer  restrictions  set  forth in the
Subscription  Agreements and any action taken to encumber such securities by the
holders thereof;

                         (H) the Placement  Warrants,  when issued in accordance
with  the  terms  of  this  Agreement  and/or  the  Subscription  Agreement,  as
applicable,  for the  consideration  expressed  therein,  will have been validly
issued and will constitute legal,  valid and binding  obligations of the Company
enforceable  against  the Company in  accordance  with their  respective  terms,
except  as  such  enforceability  may  be  limited  by  applicable   bankruptcy,
insolvency,  reorganization,  moratorium  or other laws of  general  application
relating or affecting  generally the  enforcement  of creditors'  rights and the
application  of equitable  principles  in any action,  legal or  equitable.  The
Preferred  Stock to be issued  as of the date of such  opinion,  when  issued in
accordance with the terms of this Agreement and the Subscription  Agreements for
the  consideration  expressed  therein,  will have been validly  issued and such
Preferred  Stock  will be fully  paid and  nonassessable.  The  Preferred  Stock
issuable upon exercise of the Placement Warrants, when issued in accordance with
the terms thereof for the consideration  expressed therein,  will have been duly
issued;  such  Preferred  Stock  will be fully  paid and  nonassessable  and the
provisions of the Preferred  Stock  Certificate of Designation  will  constitute
legal,  valid and binding  obligations  of the Company  enforceable  against the
Company in accordance  with their terms,  except as such  enforceability  may be
limited

by applicable bankruptcy, insolvency,  reorganization,  moratorium or other laws
of general  application  relating or  affecting  generally  the  enforcement  of
creditors'  rights and the  application  of equitable  principles in any action,
legal or equitable. Except as set forth in the Term Sheet, the Conversion Shares
(including the Conversion  Shares  underlying the Preferred  Stock issuable upon
exercise  of the  Placement  Warrants),  subject  to the  filing  of an  amended
Certificate of Incorporation  increasing the number of authorized  shares of the
Company's  Common  Stock as  contemplated  by the Term  Sheet,  have  been  duly
authorized  and reserved for issuance and,  when issued in  accordance  with the
terms of the Preferred  Stock,  will have been validly  issued and will be fully
paid and nonassessable.

                         (I)  the  Company's   By-laws  and/or   Certificate  of
Incorporation,  as in effect as of the date of such opinion,  contain provisions
indemnifying  all directors  against  liability and absolving all directors from
liability to the Company and its  stockholders  to the maximum extent  permitted
under the laws of the State of Delaware.

                         Such  counsel  shall  state,  in  opining on any matter
stated to be subject to the  knowledge  of such  counsel,  that such counsel has
made appropriate  inquiries of officers of the Company and the Subsidiaries with
respect to the subject matter of such opinion and has reviewed all documents the
existence  of which is  disclosed  by such  inquiries  or of which such  counsel
otherwise is aware of as a result of its representation of the Company.

                         In  addition,  such  counsel  shall  state  that in the
course of the preparation of the Offering Documents, which involved, among other
things,  discussions and inquiries  concerning the various legal matters and the
review  of  certain  corporate  records,  documents  and  proceedings,   counsel
participated in conferences with certain officers and other  representatives  of
the Company and the  Placement  Agent  during which the contents of the Offering
Documents  and related  matters were  discussed.  Such counsel  shall advise the
Placement  Agent in the form of an opinion of counsel  that such  counsel has no
reason to believe that, as of each Closing Date,  the Term Sheet or any document
incorporated by reference  therein  contained any untrue statement of a material
fact relating to the Company or omitted to state a material fact relating to the
Company  required  to be stated  therein  or  necessary  to make the  statements
therein not misleading in the light of the  circumstances  under which they were
made.

                    (vi)  OPINIONS  OF  ENVIRONMENTAL  AND  PATENT  COUNSEL.  If
requested by the Placement Agent, the Placement Agent shall receive the opinions
of  environmental  counsel and patent counsel to the Company (which such counsel
shall be satisfactory to the Placement Agent in its sole discretion),  dated the
Closing Date in the form and substance satisfactory to counsel for the Placement
Agent.

                    (vii) COMFORT LETTER.  The Company shall cause the Company's
independent  public  accountants  to address  and deliver to the Company and the
Placement Agent a letter or letters (which letters are frequently referred to as
"Comfort  Letters")  dated as of each Closing Date and the effective date of the
Shelf  Registration  Statement  required  to be  filed  in  connection  with the
Subscription Agreements.

                    (viii)  OFFICER'S  CERTIFICATE.  The  Placement  Agent shall
receive an Officer's  Certificate  substantially in the form of Exhibit A hereto
and a  Secretary's  Certificate  substantially  in the form of Exhibit B hereto,
signed by the  appropriate  parties  and dated as of each  Closing  Date.  These
certificates  shall state,  among other  things,  that the  representations  and
warranties  contained  in Section 2 hereof are true and accurate in all respects
at such  Closing  Date with the same  effect as  though  expressly  made at such
Closing Date.

                    (ix) ESCROW  AGREEMENT.  The Placement Agent shall receive a
copy of a duly executed Escrow Agreement with Fleet National Bank.

                    (x) TRANSMITTAL  LETTERS.  The Placement Agent shall receive

Preferred  Stock  and  shall  receive  a  letter  from  the  Company  confirming
transmittal of the securities to the investors.

               (c) BLUE SKY. A summary blue sky survey,  at the sole cost of the
Company  (including,  without  limitation,  the legal fees and  disbursements in
connection  therewith),  shall be  prepared  by counsel to the  Placement  Agent
stating the extent to which and the  conditions  upon which  offers and sales of
the Units  may be made in  certain  jurisdictions.  It is  understood  that such
survey may be based on or rely upon (i) the  representations  of each Subscriber
set forth in the Subscription  Agreement delivered by such Subscriber,  (ii) the
representations, warranties and agreements of the Company set forth in Section 2
of this  Agreement,  (iii) the  representations  and warranties of the Placement
Agent and (iv) the  representations  of the Company set forth in the certificate
to be delivered at the Closing pursuant to paragraph (viii) of Section 3(b).

               (d) PLACEMENT FEES AND EXPENSES.  (i) Simultaneously with payment
for and  delivery of the Units at each  Closing as provided  in  paragraph  3(a)
above,  the  Company  shall at such  Closing  pay to the  Placement  Agent (i) a
commission (the "Cash  Commission")  equal to nine percent (9%) of the aggregate
purchase price of the Units sold and (ii) a  non-accountable  expense  allowance
(the "Expense  Allowance") equal to four percent (4%) of the aggregate  purchase
price of the Units sold.  The Company  shall also pay all expenses in connection
with the

qualification  of the Units under the  securities or Blue Sky laws of the states
which the Placement Agent shall designate. In addition, upon each Closing of the
sale of the Units being  offered,  the Company will sell to the Placement  Agent
and/or its  designees,  for $.001 per warrant,  preferred  stock  warrants  (the
"Placement  Warrants")  to acquire a number of newly issued  shares of Preferred
Stock  equal to ten  percent  (10%) of the number of shares of  Preferred  Stock
issued in the Offering,  exercisable  for a period of ten (10) years  commencing
six  months  after the Final  Closing  Date at an  exercise  price  equal to one
hundred  ten  percent  (110%) of the initial  offering  price of the Units.  The
Company agrees with the Placement  Agent and its successors and assigns that the
Placement  Warrants  will not be subject to  redemption  by the Company nor will
they be  callable or  mandatorily  convertible  by the  Company.  The  Placement
Warrants cannot be transferred,  sold,  assigned or hypothecated  for six months
except  that they may be  assigned in whole or in part during such period to any
NASD  member  participating  in the  Offering  or any officer or employee of the
Placement Agent or any such NASD member.  The Placement  Warrants will contain a
cashless exercise feature and antidilution  provisions and the right to have the
Conversion  Shares issuable upon  conversion of the Preferred  Stock  underlying
such warrants included on the Shelf Registration Statement.

                    (ii) The Cash  Commission,  Expense  Allowance and Placement
Warrants as set forth in this  Agreement  shall be paid to the  Placement  Agent
with respect to any investment by any investors introduced to the Company by the
Placement  Agent  ("Covered  Investors")  in the  event  that any  such  Covered
Investor  purchases  securities  from the Company  during the twelve (12) months
following the Final Closing Date of the Offering.

               (e) NO ADVERSE  CHANGES.  There shall not have  occurred,  at any
time prior to the  Closing,  (i) any  domestic or  international  event,  act or
occurrence which has disrupted,  or in the Placement Agent's  determination will
in the  immediate  future  disrupt,  the  securities  markets;  (ii)  a  general
suspension of, or a general  limitation on prices for,  trading in securities on
the New York Stock Exchange,  the American Stock  Exchange,  the Nasdaq National
Market, the Nasdaq SmallCap Market, or in the over-the-counter market; (iii) any
outbreak of major hostilities or other national or international  calamity; (iv)
any  banking  moratorium  declared  by a state  or  federal  authority;  (v) any
moratorium  declared in foreign exchange trading by major international banks or
other persons; (vi) any material interruption in the mail service or other means
of communication  within the United States; (vii) any material adverse change in
the business, properties, assets, results of operations,  financial condition or
prospects of the Company;  or (viii) any change in the market for  securities in
general  or in  political,  financial,  or  economic  conditions  which,  in the
Placement Agent's reasonable judgment,  makes it inadvisable to proceed with the
offering, sale and delivery of the Units.

          4.   COVENANTS OF THE COMPANY.

               (a) USE OF PROCEEDS. Except as set forth on Schedule 4(a) hereto,
the  Company  shall  not use  any  proceeds  from  the  Offering  to  repay  any
indebtedness  of the Company,  including but not limited to any  indebtedness to
current  executive  officers  or  principal  stockholders  of the  Company,  but
excluding  accounts payable to  non-affiliates  incurred in the ordinary course,
including   scheduled   repayments   of  principal   and  interest  on  existing
indebtedness and lines of credit secured by the receivables and inventory of the
Company,  and such other  indebtedness as shall be agreed upon in writing by the
Company and the Placement Agent.

               (b) EXPENSES OF OFFERING.  The Company shall be  responsible  for
and shall bear all expenses  incurred in connection with the proposed  Offering,
including  but not limited to, the costs of preparing and  duplicating  the Term
Sheet and all exhibits thereto; the costs of preparing, printing and filing with
the Commission the Shelf Registration  Statement and amendments,  post-effective
amendments  and  supplements  thereto;  preparing,  duplicating  and  delivering
exhibits  thereto  and  copies  of  the  preliminary,   final  and  supplemental
prospectus;  preparing,  duplicating and delivering (including by facsimile) all
selling  documents,  including but not limited to the Term Sheet,  the Placement
Agency  Agreement,   Subscription  Agreements,   Placement  Warrants,  blue  sky
memorandum and stock and warrant  certificates;  blue sky fees,  filing fees and
legal fees and  disbursements  of the  Placement  Agent's  counsel  and blue sky
counsel; fees and disbursements of the transfer and warrant agent; the cost of a
total of two sets of bound  closing  volumes  for the  Placement  Agent  and its
counsel; and the cost of three tombstone  advertisements,  at least one of which
shall appear in a national business newspaper and one of which shall appear in a
major New York newspaper (or, at the option of the Placement  Agent,  forty (40)
lucite deal mementos) (collectively, the "Company Expenses"). The Company agrees
to use a printer  designated  by the  Placement  Agent  and which is  reasonably
acceptable  to the  Company.  The  Company  shall pay to the  Placement  Agent a
non-accountable  expense  allowance  equal to 4% of the  total  proceeds  of the
Offering (the "Expense  Allowance"),  of which twenty thousand dollars ($20,000)
shall have been paid upon  execution of the Letter of Intent between the Company
and the  Placement  Agent  dated  April 16,  1997 and  twenty  thousand  dollars
($20,000)  of which  shall be due and  payable  upon the date the Term  Sheet is
completed,  to  cover  the cost of the  Placement  Agent's  mailing,  telephone,
telecopy,  travel,  due diligence  meetings and other similar expenses excluding
legal fees of the  Placement  Agent's  counsel and blue sky counsel  (which fees
shall be the responsibility of the Company as provided above and any other items
designated above as Company Expenses).  Such prepaid expense allowances shall be
non-refundable.  If the proposed  financing is not completed because the Company
prevents  it  or  because  of  a  breach  by  the  Company  of  any   covenants,
representations or warranties contained herein, then the Company shall pay

                                                                  EXECUTION COPY

to the Placement  Agent a fee of one hundred  thousand  dollars  ($100,000)  (in
addition  to the  Company  Expenses  for which the  Company  shall in all events
remain liable).

               (c)  NOTIFICATION.  The Company shall notify the Placement  Agent
immediately,  and in writing,  (A) when any event shall have occurred during the
period  commencing  on the date hereof and ending on the later of the Closing or
the Final Closing Date as a result of which the Offering Documents would include
any untrue  statement  of a  material  fact or omit to state any  material  fact
required to be stated  therein or necessary to make the  statements  therein not
misleading in light of the  circumstances  under which they were made and (B) of
the receipt of any notification  with respect to the  modification,  rescission,
withdrawal or suspension of the  qualification or registration of the Units, the
Placements Warrants and the Registrable Capital Stock (as defined herein), or of
any exemption from such registration or qualification,  in any jurisdiction. The
Company  will  use  its  best  efforts  to  prevent  the  issuance  of any  such
modification,   rescission,   withdrawal   or   suspension   and,  if  any  such
modification, rescission, withdrawal or suspension is issued and you so request,
to obtain the lifting thereof as promptly as possible.

               (d) BLUE SKY.  The Company  will use its best  efforts to qualify
the  Units  for  offering  and  sale  under  exemptions  from  qualification  or
registration  requirements  under  the  securities  or "blue  sky"  laws of such
jurisdictions as the Placement Agent may reasonably  request;  provided however,
that the Company will not be obligated to qualify as a dealer in  securities  in
any  jurisdiction  in  which  it is not  so  qualified.  The  Company  will  not
consummate any sale of Units in any jurisdiction in which it is not so qualified
or in any manner in which such sale may not be lawfully made.

               (e) REGISTRATION  STATEMENT FILING.  The Company will, as soon as
practicable, but not later than 30 days after the Final Closing Date, (i) file a
shelf registration  statement (the "Shelf Registration  Statement") with respect
to (i) the  Conversion  Shares and (ii) the shares of Common Stock issuable upon
conversion of the Preferred Stock underlying the Placement  Warrants (as defined
in paragraph 3(d)) (together,  the "Registrable Capital Stock") with the SEC and
use its  best  efforts  to  have  such  Shelf  Registration  Statement  declared
effective by the SEC prior to the date which is 75 days after the Final  Closing
Date (subject to penalties for failure to effect such  registration  in the time
frames required as set forth in the  Subscription  Agreement) and (b) cause such
Shelf Registration  Statement to remain effective until such date as the holders
of the  securities  have  completed  the  distribution  described  in the  Shelf
Registration Statement or at such time that such shares are no longer, by reason
of Rule 144(k) under the Securities Act,  required to be registered for the sale
thereof by such holders.  If requested by the Placement Agent, and in accordance
with applicable  securities laws, the Shelf  Registration  Statement shall cover
the direct sale

of such  Registrable  Capital  Stock  to the  holders  of such  securities.  The
Registrable  Capital  Stock will be subject to a staggered  "lock-up"  as may be
deemed advisable by the Placement Agent.

               (f) FORM D FILING. The Company shall file five copies of a Notice
of Sales of Securities on Form D with the Commission no later than 15 days after
the first Closing Date. The Company shall file promptly such  amendments to such
Notice on Form D as shall become necessary and shall also comply with any filing
requirement imposed by the laws of any state or jurisdiction in which offers and
sales are made. The Company shall furnish the Placement Agent with copies of all
such filings.

               (g)  PRESS  RELEASES,   ETC.  Except  as  otherwise  required  by
applicable law, the Company shall not, during the period  commencing on the date
hereof and ending  thirty  days after the Final  Closing  Date,  issue any press
release or other communication,  make any written or oral statement to any media
organization  or  publication  or hold any  press  conference,  presentation  or
seminar,  or engage in any other  publicity  with  respect to the  Company,  its
financial condition,  results of operations,  business,  properties,  assets, or
liabilities, or the Offering, without the prior written consent of the Placement
Agent.  Upon the request of the Placement  Agent,  the Company shall make a Rule
135(c) (under the Securities Act of 1933, as amended)  announcement prior to the
commencement of the Offering.

               (h) PUBLIC  DOCUMENTS.  Following  the Final  Closing Date of the
Offering,  the  Company  will  furnish to the  Placement  Agent:  (i) as soon as
practicable  (but  in the  case  of the  annual  report  of the  Company  to its
stockholders,  within 120 days after the end of each fiscal year of the Company)
one copy of: (A) its annual  report to its  stockholders  (which  annual  report
shall contain financial statements audited in accordance with generally accepted
accounting  principles  in the United  States of America by a firm of  certified
public accountants of recognized standing),  (B) if not included in substance in
its annual report to stockholders, its annual report on Form 10-KSB, (C) each of
its quarterly reports to its  stockholders,  and if not included in substance in
its quarterly reports to stockholders,  its quarterly report on Form 10-QSB, (D)
each of its  current  reports  on Form  8-K,  and (E) a copy of the  full  Shelf
Registration Statement,  (the foregoing, in each case, excluding exhibits);  and
(ii) upon reasonable request,  all exhibits excluded by the parenthetical to the
immediately  preceding  clause  4(h)(i)(E)  and all  other  information  that is
generally  available  to the public.  In addition,  the Company upon  reasonable
request will meet with the Placement Agent or its representatives to discuss all
information relevant for disclosure in any Shelf Registration Statement covering
shares  purchased by Purchasers  from the Company and offered by them for resale
and will cooperate in any reasonable  investigation  undertaken by the Placement
Agent for the purpose of

confirming  the  accuracy of the Shelf  Registration  Statement,  including  the
production of information at the Company's offices.

               (i)  RESTRICTIONS ON SECURITIES.  During the eighteen (18) months
following the Closing of the Offering,  the Company shall not, without the prior
written consent of the Placement  Agent,  offer or sell any of its securities in
reliance on  Regulation S of the  Securities  Act.  During the  18-month  period
following the date hereof, (i) the Placement Agent shall have the right of first
refusal to act as  placement  agent for the  offering of any  securities  of the
Company and (ii) the Company will not extend the expiration date or decrease the
exercise price of any options, warrants, convertible securities or other similar
security  purchase  rights  without the prior  written  consent of the Placement
Agent.

               (j)  LISTING.  The  Company  will take all  action  necessary  to
promptly file an Application for Listing of Additional  Shares with the New York
Stock Exchange,  the American Stock Exchange,  the Nasdaq National  Market,  the
Nasdaq SmallCap Market, or the OTC Electronic Bulletin Board, as applicable,  in
accordance  with  Regulation  M under the  Exchange  Act  and/or  take any other
necessary  action to enable the Common Stock into which the  Preferred  Stock is
convertible  (including  the  Common  Stock  issuable  upon  conversion  of  the
Preferred Stock underlying the Placement Warrants) to trade thereon.

               (k) FINANCIAL  ADVISORY  AGREEMENT.  Upon the Final Closing Date,
the Company and the Placement  Agent will enter into an engagement  agreement in
form and substance  satisfactory to the Placement Agent (the "Financial Advisory
Agreement")  whereby the  Placement  Agent will act as the  Company's  financial
advisor.   Such  engagement  will  provide  that  the  Placement  Agent  receive
out-of-pocket expenses and standard success fees.

               (l)  NO  OFFERINGS.  Pending  completion  or  termination  of the
Offering in accordance with the terms of this Agreement, the Company agrees that
it will not enter into an agreement  (whether  binding or not) or negotiate with
any other person or entity relating to a possible public or private  offering or
placement  of  its  securities  (other  than  in  connection  with  a  corporate
partnership,  strategic alliance or government funding).

               (m) NO  STATEMENTS.  The  Company  shall  not use the name of the
Placement  Agent or any  officer,  director,  employee  or  shareholder  thereof
without the express written consent of the Placement Agent and such person.

               (n)  COMPANY   INSIDERS.   Officers,   directors   or   principal
stockholders  of the Company may invest in the  Offering.  Any such  investments
will

                                                                  EXECUTION COPY

be  included in  calculating  whether the 30 Units have been sold in the Minimum
Offering,  whether  the 50 Units  have been sold in the  Maximum  Offering,  and
whether the 30 Units have been sold pursuant to the over-allotment.

               (o) PLACEMENT AGENT INSIDERS. Certain affiliates of the Placement
Agent may purchase Units in the Offering. Affiliates of the Placement Agent will
invest net of cash  commissions and expenses.  Accordingly,  the Placement Agent
will not receive a commission on the Units  purchased by its  affiliates and the
Company will receive net proceeds  equivalent to the net proceeds  received from
the purchase of Units by persons not affiliated  with the Placement  Agent.  The
aggregate offering price of any such investments will be included in calculating
whether  the 30 Units have been sold in the  Minimum  Offering,  whether  the 50
Units have been sold in the Maximum Offering, and whether the 30 Units have been
sold pursuant to the over-allotment option.

          5.   INDEMNIFICATION.

               (a) The  Company  agrees  to  indemnify  and  hold  harmless  the
Placement Agent and each Selected Dealer, if any, and their respective partners,
affiliates,    shareholders,     directors,    officers,    agents,    advisors,
representatives,  employees,  counsel and controlling persons within the meaning
of the  Securities  Act (a "Paramount  Indemnified  Party")  against any and all
losses, liabilities, claims, damages and expenses whatsoever (and all actions in
respect  thereof),  and to reimburse such Paramount  Indemnified Party for legal
fees and related expenses as incurred (including,  but not limited to, the costs
of giving  testimony  or  furnishing  documents  in  response  to a subpoena  or
otherwise, the costs of investigating, preparing, pursuing or defending any such
action or claim  whether or not  pending or  threatened  and  whether or not the
Placement Agent or any Paramount Indemnified Party is a party thereto),  insofar
as such losses,  liabilities,  claims,  damages or expenses arise out of, relate
to,  are  incurred  in  connection  with or are in any way a  result  of (i) the
engagement of the Placement  Agent  pursuant to this Agreement and in connection
with the  transactions  contemplated  by this  Agreement and the other  Offering
Documents (the "Engagement"), including any modifications or future additions to
such engagement and related activities prior to the date hereof, (ii) any act by
the Placement Agent or any Paramount  Indemnified Party taken in connection with
the  Engagement,  (iii) a breach of any  representation,  warranty,  covenant or
agreement of the Company contained in this Agreement, (iv) the employment by the
Company of any device,  scheme or artifice  to defraud,  or the  engaging by the
Company in any act,  practice  or course of  business  which  operates  or would
operate  as a fraud or  deceit,  or any  conspiracy  with  respect  thereto,  in
connection  with the sale of the Units,  or (v) any untrue  statement or alleged
untrue statement of a material fact contained in the

                                                                  EXECUTION COPY

Offering  Documents or the omission or alleged omission  therefrom of a material
fact  necessary  in  order  to make  the  statements  therein,  in  light of the
circumstances  under which they were made, not  misleading,  provided,  however,
that the  Company  will not be liable in any such case if and to the extent that
any such loss,  claim,  damage,  liability or expense  arises out of or is based
upon an untrue  statement  or alleged  untrue  statement  or omission or alleged
omission so made in conformity with information  furnished by any such Paramount
Indemnified Party in writing specifically for use in the Offering Documents.

               (b) The Company agrees to indemnify and hold harmless a Paramount
Indemnified Party to the same extent as the foregoing indemnity,  and subject to
the limitations set forth therein,  against any and all loss, liability,  claim,
damage and expense whatsoever directly arising out of the exercise by any person
of any right under the  Securities  Act or the Exchange Act or the securities or
Blue Sky laws of any state on  account  of  violations  of the  representations,
warranties or agreements set forth in Section 2 hereof.

               (c)   Promptly   after   receipt   by  a   person   entitled   to
indemnification  pursuant to subsection (a) or (b) (an  "indemnified  party") of
this Section of notice of the commencement of any action,  the indemnified party
will,  if a claim in  respect  thereof is to be made  against a person  granting
indemnification (an "indemnifying party") under this Section,  notify in writing
the  indemnifying  party of the  commencement  thereof;  but the  omission so to
notify the  indemnifying  party will not relieve it from any liability  which it
may have to the indemnified party otherwise than under this Section. In case any
such  action is brought  against  an  indemnified  party,  and it  notifies  the
indemnifying party of the commencement  thereof,  the indemnifying party will be
entitled to  participate  in, and, to the extent that it may wish,  jointly with
any other indemnifying party similarly notified,  to assume the defense thereof,
subject to the provisions herein stated, with counsel reasonably satisfactory to
the  indemnified  party,  and after  notice from the  indemnifying  party to the
indemnified  party  of its  election  so to  assume  the  defense  thereof,  the
indemnifying  party will not be liable to the indemnified party for any legal or
other expenses subsequently incurred by the indemnified party in connection with
the defense thereof other than reasonable costs of investigation incurred at the
request of the indemnifying party. The indemnified party shall have the right to
employ  separate  counsel in any such action and to  participate  in the defense
thereof,  but the fees and expenses of such counsel  shall not be at the expense
of the indemnifying  party if the indemnifying  party has assumed the defense of
the action  with  counsel  reasonably  satisfactory  to the  indemnified  party;
provided  that the fees and expenses of such counsel  shall be at the expense of
the  indemnifying  party  if  (i)  the  employment  of  such  counsel  has  been
specifically authorized in writing by the indemnifying party or

<PAGE>

                                                                  EXECUTION COPY

(ii) the named  parties to any such action  (including  any  impleaded  parties)
include both the indemnified party or parties and the indemnifying party and, in
the  judgment of the  indemnified  party,  it is advisable  for the  indemnified
parties to be represented by separate  counsel,  in which case the  indemnifying
party shall not have the right to assume the defense of such action on behalf of
the  indemnified  party or  parties,  it  being  understood,  however,  that the
indemnifying party shall not, in connection with any one such action or separate
but substantially  similar or related actions in the same  jurisdiction  arising
out of the  same  general  allegations  or  circumstances,  be  liable  for  the
reasonable fees and expenses of more than one separate firm of attorneys for the
indemnified  party or parties.  No settlement,  compromise,  consent to entry of
judgment or other termination of any action  (collectively,  "Terminations")  in
respect  of  which  a  Paramount  Indemnified  Party  may  seek  indemnification
hereunder  (whether or not any Paramount  Indemnified  Party is a party thereto)
shall be made without the prior  written  consent of the  Paramount  Indemnified
Party,  which  such  consent  may be  withheld  at the sole  discretion  of such
Paramount Indemnified Party,  provided,  however, that the foregoing requirement
of prior written consent for Terminations shall not apply to the Placement Agent
who may agree to such  Terminations  without  the prior  written  consent of any
Paramount Indemnified Party.

               (e) Notwithstanding any of the provisions of this Agreement,  the
aggregate  indemnification  or  contribution  of the  Placement  Agent for or on
account of any  losses,  claims,  damages,  liabilities  or  actions  under this
Section 5, Section 6 or any other  applicable  section of this Agreement,  shall
not  exceed the Cash  Commissions  actually  paid to the  Placement  Agent.  The
indemnity and  contribution  agreements by the Company  contained in subsections
(a),  (b)  and  (c)  of  this  Section  5 and  Section  6,  and  the  covenants,
representations  and warranties of the Company set forth in Sections 1, 2, 3 and
4 shall  remain  operative  and in full force and effect  regardless  of (i) any
investigation made by the Placement Agent, on the Placement Agent's behalf or by
or on behalf of any person who controls the Placement Agent,  (ii) acceptance of
any of the  Units  and  payment  therefor  or  (iii)  any  termination  of  this
Agreement, and shall survive the delivery of the Units, and any successor of the
Placement  Agent or of any person who controls the Placement  Agent, as the case
may be,  shall be  entitled  to the  benefit of such  respective  indemnity  and
contribution  agreements.  The  indemnity  and  contribution  agreements  by the
Company  contained in subsections (a), (b) and (c) of this Section 5 and Section
6 shall be in addition to any liability which the Company may otherwise have.

          6.   CONTRIBUTION.

               (a) To provide  for just and  equitable  contribution,  if (i) an
indemnified party makes a claim for indemnification pursuant to Section 5 but it
is

<PAGE>

Paramount Capital, Inc.
Page 25

                                                                  EXECUTION COPY

found in a final judicial  determination,  by a court of competent jurisdiction,
not subject to further appeal, that such  indemnification may not be enforced in
such case, even though this Agreement  expressly provides for indemnification in
such case, or (ii) any  indemnified  or  indemnifying  party seeks  contribution
under the  Securities  Act,  the  Exchange  Act or  otherwise,  then the Company
(including  for  this  purpose  any  contribution  made by or on  behalf  of any
officer, director,  employee or agent for the Company, or any controlling person
of the  Company),  on the one hand,  and the  Placement  Agent and any  Selected
Dealers  (including  for this  purpose  any  contribution  by or on behalf of an
indemnified  party),  on  the  other  hand,  shall  contribute  to  the  losses,
liabilities, claims, damages and expenses whatsoever to which any of them may be
subject, in such proportions as are appropriate to reflect the relative benefits
received  by the  Company,  on the one  hand,  and the  Placement  Agent and the
Selected Dealers, on the other hand; provided,  however,  that if applicable law
does not permit such allocation,  then other relevant  equitable  considerations
such as the  relative  fault of the  Company  and the  Placement  Agent  and the
Selected  Dealers in  connection  with the facts which  resulted in such losses,
liabilities,  claims, damages, and expenses shall also be considered. In no case
shall the Placement  Agent or a Selected  Dealer be responsible for a portion of
the  contribution  obligation  in  excess  of the  compensation  received  by it
pursuant to Section 3 hereof or the Selected Dealer  Agreement,  as the case may
be. No person  guilty of a  fraudulent  misrepresentation  shall be  entitled to
contribution   from  any   person   who  is  not   guilty  of  such   fraudulent
misrepresentation.  For  purposes of this  Section 6, each  person,  if any, who
controls the Placement  Agent or a Selected Dealer within the meaning of Section
15 of the  Securities Act or Section 20(a) of the Exchange Act and each officer,
director,  stockholder,  employee and agent of the Placement Agent or a Selected
Dealer, shall have the same rights to contribution as the Placement Agent or the
Selected  Dealer,  and each person,  if any who controls the Company  within the
meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act
and each officer,  director,  employee and agent of the Company,  shall have the
same  rights  to  contribution  as the  Company,  subject  in  each  case to the
provisions  of this  Section  6.  Anything  in this  Section  6 to the  contrary
notwithstanding,  no party shall be liable for contribution  with respect to the
settlement of any claim or action  effected  without its written  consent.  This
Section  6 is  intended  to  supersede  any  right  to  contribution  under  the
Securities Act, the Exchange Act or otherwise.

          7.   MISCELLANEOUS.

               (a) SURVIVAL. Any termination of the Offering without any Closing
shall be without  obligation on the part of any party except that the provisions
regarding  fees and expenses  contained  in Section  4(b),  the  indemnification
provided in

                                                                  EXECUTION COPY

Section 5 hereof and the contribution provided in Section 6 hereof shall survive
any termination and shall survive any Closing.

               (b)   REPRESENTATIONS,   WARRANTIES   AND  COVENANTS  TO  SURVIVE
DELIVERY.  Except as provided in Section 7(a), the  respective  representations,
warranties,  indemnities,  agreements,  covenants  and other  statements  of the
Company and the Placement Agent as of the date hereof shall survive execution of
this Agreement and delivery of the Units and the termination of this Agreement.

               (c) NO OTHER  BENEFICIARIES.  This  Agreement is intended for the
sole and exclusive benefit of the parties hereto and their respective successors
and controlling persons, and no other person, firm or corporation shall have any
third-party beneficiary or other rights hereunder.

               (d)  GOVERNING  LAW.  This  Agreement  shall be  governed  by and
construed in accordance  with the law of the State of New York without regard to
conflict of law provisions.

               (e)  COUNTERPARTS.  This Agreement may be signed in  counterparts
with the same effect as if both parties had signed one and the same instrument.

               (f) NOTICES. Any communications  specifically  required hereunder
to be in writing, if sent to the Placement Agent, will be mailed,  delivered and
confirmed to it at Paramount  Capital,  787 Seventh Avenue,  New York, New York,
10019,  Att:  Michael  S.  Weiss  and if sent to the  Company,  will be  mailed,
delivered  or  telegraphed  and  confirmed  to  it  at  Conversion  Technologies
International,  Inc., 3452 Lake Lynda Drive,  Suite 280, Orlando,  Florida 32817
Attn: President.

               (g)  TERMINATION.  Subject  to the  general  survival  provisions
contained in Sections 7(a) and 7(b),  this Agreement may be terminated by either
party prior to any Closing upon written notice to the other party.

               (h)  ENTIRE  AGREEMENT.  This  Agreement  constitutes  the entire
agreement  of the  parties  with  respect to the  matters  herein  referred  and
supersedes all prior agreements and  understandings,  written and oral,  between
the parties with respect to the subject  matter  hereof.  Neither this Agreement
nor any term hereof may be changed,  waived or terminated orally, but only by an
instrument  in writing  signed by the party  against  which  enforcement  of the
change, waiver or termination is sought.

                              OFFICERS' CERTIFICATE

                                 August __, 1997

          I,  _____________,  certify  that  I am  the  ____________________  of
Conversion  Technologies  International,   Inc.,  a  Delaware  corporation  (the
"Company"),  and that, as such, I am authorized to execute this  certificate  on
behalf of the  Company.  All  capitalized  terms used  herein but not  otherwise
defined herein shall the meanings ascribed to such terms in the Agency Agreement
(as defined  below).  Reference  is made herein to the closing  held on [ ] (the
"Closing Date").  I do hereby certify that I have carefully  examined all of the
Offering  Documents (as defined in the Placement  Agency  Agreement  dated as of
April 1, 1997  between the Company and  Paramount  Capital,  Inc.  (the  "Agency
Agreement")), and do hereby further certify that:

          1. All of the  representations and warranties of the Company contained
in the  subscription  agreements  (the  "Subscription  Agreements")  between the
Company and the purchasers (the "Purchasers") of the Units of Preferred Stock of
the Company contemplated by the Company's  Confidential Term Sheet, dated August
8, 1997 (as supplemented, the "Term Sheet") are true and correct in all material
respects on the Closing Date with the same force and effect as if made on and as
of the Closing Date,  and the Company has performed all covenants and agreements
and has satisfied all conditions in the Subscription  Agreements to be performed
or satisfied on its part before the Closing Date in all material respects.

          2. The Term Sheet does not contain any untrue  statement of a material
fact or omit to  state  any  fact  required  to be  stated  in order to make the
statements  therein not misleading as of the Closing Date. Since the date of the
Term Sheet, no event has occurred concerning which information is required to be
contained  in an  amended  or  supplemented  Term  Sheet  concerning  which such
information is not contained herein.

          3. All of the  representations and warranties of the Company contained

                  Conversion Technologies International, Inc.


         This certifies that FOR VALUE RECEIVED __________________ or registered
assigns (the "Registered Holder") is the owner of the number of Class A Warrants
("Class A Warrants")  specified above. Each Class A Warrant  represented  hereby
initially  entitles the Registered Holder to purchase,  subject to the terms and

hereinafter  defined),  one fully paid and nonassessable  share of Common Stock,

a Delaware  corporation (the "Company"),  and one Class B Warrant of the Company
at any  time  between  ____________  and the  Expiration  Date  (as  hereinafter
defined),  upon the presentation and surrender of this Warrant  Certificate with

to the exercise of the Class A Warrants represented hereby unless a registration
statement  under the  Securities  Act of 1933, as amended,  with respect to such
securities is effective. The Company has covenanted and agreed that it will file
a  registration  statement  and will use its best  efforts  to cause the same to

the Class A Warrants are outstanding.  This Class A Warrants  represented hereby
shall not be exercisable by a Registered Holder in any state where such exercise
would be unlawful.

         This Warrant Certificate is exchangeable,  upon the surrender hereof by

Warrant Certificate or Warrant  Certificates of like tenor representing an equal
aggregate number of Class A Warrants,  each of such new Warrant  Certificates to
represent  such  number  of Class A  Warrants  as shall  be  designated  by such
Registered  Holder at the time of such surrender.  Upon the presentment with any
applicable  transfer  fee in  addition to any tax or other  governmental  charge
imposed in connection  therewith,  for  registration of transfer of this Class A
Warrant  Certificate  at such  office,  a new  Warrant  Certificate  or  Warrant
Certificates  representing an equal aggregate number of Class A Warrants will be
issued to the  transferee  in  exchange  therefor,  subject  to the  limitations
provided in the Warrant Agreement.

         Prior to the exercise of any Class A Warrant  represented  hereby,  the
Registered  Holder shall not be entitled to any rights of a  stockholder  of the
Company,  including,  without  limitation,  the  right  to  vote  or to  receive
dividends  or other  distributions,  and shall not be  entitled  to receive  any
notice of any  proceedings  of the  Company,  except as  provided in the Warrant
Agreement.

of the Company,  at a  redemption  price of $.05 per Class A Warrant at any time

Company and the Warrant  Agent may deem and treat the  Registered  Holder as the
absolute owner hereof

and of each Class A Warrant represented hereby (notwithstanding any notations of

                         CLASS B WARRANT CERTIFICATE FOR
                            PURCHASE OF COMMON STOCK


                   CONVERSION TECHNOLOGIES INTERNATIONAL, INC.


         This certifies that FOR VALUE RECEIVED __________________ or registered
assigns (the "Registered Holder") is the owner of the number of Class B Warrants
specified above. Each Class B Warrant  represented hereby initially entitles the
Registered Holder to purchase,  subject to the terms and conditions set forth in
this Warrant Certificate and the Warrant Agreement (as hereinafter defined), one
fully paid and nonassessable  share of Common Stock,  $.00025 par value ("Common
Stock"), of Conversion Technologies International,  Inc., a Delaware corporation
(the  "Company"),  at any time between  ____________ and the Expiration Date (as
hereinafter  defined),  upon the  presentation  and  surrender  of this  Warrant
Certificate with the Subscription  Form on the reverse hereof duly executed,  at
the  corporate  office of  American  Stock  Transfer & Trust  Company as Warrant
Agent, or its successor (the "Warrant  Agent"),  accompanied by payment of $7.80
(the  "Purchase  Price") in lawful money of the United States of America in cash
or by official bank or certified check made payable to the Company.

         This Warrant  Certificate and each Class B Warrant  represented  hereby
are  issued  pursuant  to and are  subject  in all  respects  to the  terms  and
conditions set forth in the Warrant Agreement (the "Warrant  Agreement"),  dated

subject to modification or adjustment.

hereby,  the Company  shall cancel this Warrant  Certificate  upon the surrender
hereof and shall execute and deliver a new

redeemed.  If such date  shall in the State of New York be a holiday or a day on

to the exercise of the Class B Warrants represented hereby unless a registration
statement  under the  Securities  Act of 1933, as amended,  with respect to such
securities is effective. The Company has covenanted and agreed that it will file
a  registration  statement  and will use its best  efforts  to cause the same to
become effective and to keep such  registration  statement  current while any of
the Class B Warrants are outstanding.  This Class A Warrants  represented hereby
shall not be exercisable by a Registered Holder in any state where such exercise
would be unlawful.

         This Warrant Certificate is exchangeable,  upon the surrender hereof by
the Registered  Holder at the corporate  office of the Warrant Agent,  for a new
Warrant Certificate or Warrant  Certificates of like tenor representing an equal
aggregate number of Class B Warrants,  each of such new Warrant  Certificates to
represent  such  number  of Class B  Warrants  as shall  be  designated  by such
Registered  Holder at the time of such surrender.  Upon the presentment with any
applicable  transfer  fee in  addition to any tax or other  governmental  charge
imposed in connection  therewith,  for  registration of transfer of this Class B
Warrant  Certificate  at such  office,  a new  Warrant  Certificate  or  Warrant
Certificates  representing an equal aggregate number of Class B Warrants will be
issued to the  transferee  in  exchange  therefor,  subject  to the  limitations
provided in the Warrant Agreement.

         Prior to the exercise of any Class B Warrant  represented  hereby,  the
Registered  Holder shall not be entitled to any rights of a  stockholder  of the
Company,  including,  without  limitation,  the  right  to  vote  or to  receive
dividends  or other  distributions,  and shall not be  entitled  to receive  any
notice of any  proceedings  of the  Company,  except as  provided in the Warrant
Agreement.

of the Company,  at a  redemption  price of $.05 per Class A Warrant at any time

Agreement)  for the Common  Stock  shall  exceed  $10.95  per  share.  Notice of
redemption shall be given not later than the thirtieth day before the date fixed
for redemption,  all as provided in the Warrant Agreement. On and after the date

                  FOR VALUE RECEIVED, CONVERSION TECHNOLOGIES
INTERNATIONAL,  INC., a Delaware  corporation (the "COMPANY"),  hereby certifies
that [ ], or its permitted assigns, is entitled to purchase from the Company, at
any time or from time to time  commencing  on JULY 21,  1997,  and prior to 5:00
P.M., New York City time, on JULY 21, 2002 (the  "TERMINATION  DATE"), [ ] fully
paid and non-assessable shares of the Common Stock, $.00025 par value per share,
of the Company at an  exercise  price  equal to $1.3125  (Hereinafter,  (i) said
Common Stock,  together with any other equity  securities which may be issued by
the Company with respect thereto or in substitution  therefor, is referred to as
the "COMMON STOCK", (ii) the shares of the Common Stock purchasable hereunder or
under any other Warrant (as hereinafter defined) are referred to as the "WARRANT
SHARES",  (iii) the  aggregate  purchase  price  payable for the Warrant  Shares
hereunder  is  referred  to as the  "AGGREGATE  WARRANT  PRICE",  (iv) the price
payable  for each of the  Warrant  Shares  hereunder  is referred to as the "PER
SHARE WARRANT PRICE", (v) this Warrant,  all similar Warrants issued on the date
hereof and all warrants  hereafter  issued in exchange or substitution  for this
Warrant or such similar  Warrants are referred to as the "WARRANTS" and (vi) the
holder of this  Warrant is  referred to as the  "HOLDER"  and the holder of this
Warrant and all other Warrants or Warrant Shares issued upon the exercise of any
Warrant are referred to as the  "HOLDERS").  The Aggregate  Warrant Price is not
subject to  adjustment.  The Per Share Warrant Price is subject to adjustment as
hereinafter provided; in the event of any such adjustment, the number of Warrant
Shares shall be adjusted by dividing the

<PAGE>

Aggregate  Warrant Price by the Per Share  Warrant  Price in effect  immediately
after such adjustment.

         1.  EXERCISE OF WARRANT.

         (a) This Warrant may be exercised, in whole at any time or in part from
time to time,  commencing on July 21, 1997 and prior to the Termination Date, by
the holder:

               (i) by the surrender of this Warrant (with the  subscription form
          at  the  end  hereof  duly  executed)  at the  address  set  forth  in
          Subsection 9(a) hereof,  together with proper payment of the Aggregate
          Warrant Price,  or the  proportionate  part thereof if this Warrant is
          exercised in part,  with payment for Warrant  Shares made by certified
          or official bank check payable to the order of the Company; or

               (ii) by the surrender of this Warrant (with the cashless exercise
          form at the end hereof duly  executed) (a "CASHLESS  EXERCISE") at the
          address set forth in Subsection  9(a) hereof.  Such  presentation  and
          surrender  shall be deemed a waiver of the Holder's  obligation to pay
          the Aggregate Warrant Price, or the proportionate part thereof if this
          Warrant is exercised in part. In the event of a Cashless Exercise, the
          Holder shall  exchange  its Warrant for that number of Warrant  Shares
          subject  to such  Cashless  Exercise  multiplied  by a  fraction,  the
          numerator  of which shall be the  difference  between the then current
          Market  Price per share (as  hereinafter  defined) of Common Stock and
          the Per Share Warrant Price, and the denominator of which shall be the
          then current Market Price per share of Common Stock.  The then current
          market  price per share of the Common  Stock at any date (the  "MARKET
          PRICE")  shall be deemed to be the last sale price of the Common Stock
          on the business day prior to the date of the Cashless  Exercise or, in
          case no such reported sales take place on such day, the average of the
          last reported bid and asked prices of the Common Stock on such day, in
          either case on the principal national securities exchange on which the
          Common  Stock is  admitted  to trading or listed,  or if not listed or
          admitted to trading on any such exchange,  the representative  closing
          bid price of the  Common  Stock as  reported  by the  Nasdaq  National
          Market  System or the  Nasdaq  SmallCap  Market  ("NASDAQ"),  or other
          similar   organization   if  NASDAQ  is  no  longer   reporting   such
          information,  or if not so  available,  the fair  market  price of the
          Common Stock as determined in good faith by the Board of Directors.

         (b)If this Warrant is exercised in part, this Warrant must be exercised
for a number of whole  shares of the Common  Stock and the Holder is entitled to
receive a new Warrant  covering the Warrant Shares which have not been exercised
and  setting  forth  the  proportionate  part  of the  Aggregate  Warrant  Price
applicable to such Warrant Shares.  Upon surrender of this Warrant,  the Company
will (i) issue a certificate or  certificates  in the name of the Holder for the
largest  number of whole shares of the Common Stock to which the Holder shall be
entitled and, if this Warrant is exercised in whole,  in lieu of any  fractional
share of the Common  Stock to which the  Holder  shall be  entitled,  pay to the
Holder  cash in an  amount  equal to the fair  value  of such  fractional  share
(determined in such reasonable

<PAGE>

manner as the Board of  Directors  of the  Company  shall  determine),  and (ii)
deliver the other securities and properties receivable upon the exercise of this
Warrant,  if any, or the proportionate part thereof if this Warrant is exercised
in part, pursuant to the provisions of this Warrant.

         2.  RESERVATION  OF WARRANT SHARES;  LISTING.  The Company agrees that,
prior to the expiration of this Warrant,  the Company will at all times (a) have
authorized  and in  reserve,  and will keep  available,  solely for  issuance or
delivery upon the exercise of this  Warrant,  the shares of the Common Stock and
other  securities and  properties as from time to time shall be receivable  upon
the  exercise of this  Warrant,  free and clear of all  restrictions  on sale or
transfer,  except  for the  restrictions  on sale or  transfer  set forth in the
Securities Act of 1933, as amended (the "Act"),  and restrictions  created by or
on behalf of the Holder,  and free and clear of all preemptive rights and rights
of first  refusal;  and (b) when the Company  prepares and files a  registration
statement  covering the shares of Common Stock issued or issuable  upon exercise
of this Warrant with the  Securities and Exchange  Commission  (the "SEC") which
registration  statement  is declared  effective by the SEC under the Act and the
Company  lists its Common  Stock on any  national  securities  exchange or other
quotation system, it will use its reasonable best efforts to cause the shares of
Common Stock  subject to this Warrant to be listed on such exchange or quotation
system.

         3. PROTECTION AGAINST DILUTION.

         (a) If,  at any  time or from  time  to  time  after  the  date of this
Warrant,  the  Company  shall  issue or  distribute  to the holders of shares of
Common Stock evidence of its  indebtedness,  any other securities of the Company
or any cash,  property or other assets (excluding a subdivision,  combination or
reclassification, or dividend or distribution payable in shares of Common Stock,
referred to in  Subsection  3(b),  and also  excluding  cash  dividends  or cash
distributions  paid out of net profits  legally  available  therefor in the full
amount   thereof,   which  together  with  the  value  of  other  dividends  and
distributions  made substantially  concurrently  therewith or pursuant to a plan
which  includes  payment  thereof,  is  equivalent  to not  more  than 5% of the
Company's net worth) (any such non-excluded event being herein called a "SPECIAL
DIVIDEND"), the Per Share Warrant Price shall be adjusted by multiplying the Per
Share Warrant  Price then in effect by a fraction,  the numerator of which shall
be the then current  Market Price of the Common Stock less the fair market value
(as  determined  in good  faith  by the  Company's  Board of  Directors)  of the
evidence of indebtedness,  cash,  securities or property, or other assets issued
or distributed in such Special Dividend  applicable to one share of Common Stock
and the  denominator  of which  shall be the then  current  Market  Price of the
Common Stock.  An adjustment  made pursuant to this Subsection 3(a) shall become
effective immediately after the record date of any such Special Dividend.

         (b) In case the Company  shall  hereafter  (i) pay a dividend or make a
distribution on its capital stock in shares of Common Stock,  (ii) subdivide its
outstanding  shares  of Common  Stock  into a greater  number of  shares,  (iii)
combine its  outstanding  shares of Common Stock into a smaller number of shares
or (iv)  issue by  reclassification  of its  Common  Stock any shares of capital
stock of the Company, the Per Share Warrant Price

shall be adjusted to be equal to a fraction, the numerator of which shall be the
Aggregate  Warrant  Price and the  denominator  of which  shall be the number of
shares of Common Stock or other capital stock of the Company which he would have
owned  immediately  following  such  action  had  such  Warrant  been  exercised
immediately  prior thereto.  An adjustment made pursuant to this Subsection 3(b)
shall  become  effective  immediately  after  the  record  date in the case of a
dividend  or  distribution  and shall  become  effective  immediately  after the
effective date in the case of a subdivision, combination or reclassification.

         (c)  Except as  provided  in  Subsections  3(a) and  3(d),  in case the
Company  shall  hereafter  issue  or  sell  any  Common  Stock,  any  securities
convertible  into Common  Stock or any  rights,  options or warrants to purchase
Common Stock or securities  convertible  into Common  Stock,  in each case for a
price per share or entitling the holders  thereof to purchase  Common Stock at a
price per share  (determined by dividing (i) the total amount,  if any, received
or  receivable by the Company in  consideration  of the issuance or sale of such
securities  plus the total  consideration,  if any,  payable to the Company upon
exercise or conversion thereof (the "TOTAL CONSIDERATION") by (ii) the number of
additional  shares of Common Stock  issuable upon exercise or conversion of such
securities)  less than the then  either the current  Market  Price of the Common
Stock or the  current  Per  Share  Warrant  Price in  effect on the date of such
issuance or sale,  the Per Share Warrant Price shall be adjusted by  multiplying
the Per Share Warrant Price then in effect by a fraction, the numerator of which
shall be (x) the sum of (A) the number of shares of Common Stock  outstanding on
the date of such  issuance or sale plus (B) the Total  Consideration  divided by
either the  current  Market  Price of the Common  Stock or the current Per Share
Warrant Price,  whichever is greater,  and the denominator of which shall be (y)
the number of shares of Common Stock outstanding on the date of such issuance or
sale plus the maximum number of additional  shares of Common Stock issued,  sold
or issuable upon exercise or conversion of such securities.

         (d) No  adjustment  in the Per Share Warrant Price shall be required in
the case of the  issuance  by the  Company of (i) Common  Stock  pursuant to the
exercise  or  conversion  of any Warrant or any other  options,  warrants or any
convertible  securities  currently  outstanding  or  outstanding  as a result of
securities  issued  pursuant to the PPM;  provided,  that the exercise  price or
conversion price at which such options,  warrants or convertible  securities are
exercised or  converted,  as the case may be, is equal to the exercise  price or
conversion  price in effect as of the date of this  Warrant or as of the date of
issuance  with  respect to  securities  issued  pursuant  to the PPM (except for
standard anti-dilution  adjustments set forth therein) and (ii) shares of Common
Stock issued or sold  pursuant to stock  purchase or stock option plans or other
similar arrangements that are approved by the Company's Board of Directors.

         (e) In case of any capital  reorganization or reclassification,  or any
consolidation  or merger to which the  Company is a party other than a merger or
consolidation in which the Company is the continuing corporation,  or in case of
any sale or  conveyance  to another  entity of the property of the Company as an
entirety  or  substantially  as an  entirety,  or in the  case of any  statutory
exchange of securities with another corporation (including any exchange effected
in connection with a merger of a third corporation into the

<PAGE>

Company),  the Holder of this Warrant shall have the right thereafter to receive
on the exercise of this Warrant the kind and amount of securities, cash or other
property  which the Holder  would have  owned or have been  entitled  to receive
immediately after such reorganization, reclassification,  consolidation, merger,
statutory  exchange,   sale  or  conveyance  had  this  Warrant  been  exercised
immediately   prior   to   the   effective   date   of   such    reorganization,
reclassification,  consolidation, merger, statutory exchange, sale or conveyance
and in any such case, if necessary,  appropriate adjustment shall be made in the
application  of the  provisions  set forth in this Section 3 with respect to the
rights and  interests  thereafter  of the Holder of this Warrant to the end that
the provisions set forth in this Section 3 shall thereafter  correspondingly  be
made  applicable,  as nearly as may  reasonably be, in relation to any shares of
stock or other securities or property thereafter  deliverable on the exercise of
this Warrant. The above provisions of this Subsection 3(e) shall similarly apply
to  successive  reorganizations,  reclassifications,   consolidations,  mergers,
statutory exchanges, sales or conveyances.  The issuer of any shares of stock or
other  securities  or property  thereafter  deliverable  on the exercise of this
Warrant shall be responsible  for all of the  agreements and  obligations of the
Company  hereunder.   Notice  of  any  such  reorganization,   reclassification,
consolidation,  merger,  statutory  exchange,  sale  or  conveyance  and of said
provisions  so  proposed  to be made,  shall be  mailed  to the  Holders  of the
Warrants  not  less  than  30  days  prior  to  such  event.  A  sale  of all or
substantially  all of the assets of the Company for a  consideration  consisting
primarily  of  securities  shall be deemed a  consolidation  or  merger  for the
foregoing purposes.

         (f) In case any event shall occur as to which the other  provisions  of
this Section 3 are not strictly  applicable  but as to which the failure to make
any adjustment would not fairly protect the purchase rights  represented by this
Warrant in accordance with the essential  intent and principles  hereof then, in
each such case,  the  Holders of Warrants  representing  the right to purchase a
majority of the Warrant Shares subject to all outstanding Warrants may appoint a
firm  of  independent  public   accountants  of  recognized   national  standing
reasonably  acceptable to the Company,  which shall give their opinion as to the
adjustment,  if  any,  on a basis  consistent  with  the  essential  intent  and
principles  established  herein,  necessary  to  preserve  the  purchase  rights
represented  by the  Warrants.  Upon receipt of such  opinion,  the Company will
promptly  mail a copy  thereof to the Holder of this  Warrant and shall make the
adjustments  described therein. The fees and expenses of such independent public
accountants shall be borne by the Company.

         (g) No  adjustment  in the Per Share  Warrant  Price  shall be required
unless such  adjustment  would require an increase or decrease of at least $0.05
per share of Common Stock;  provided,  however,  that any  adjustments  which by
reason of this  Subsection  3(g) are not  required  to be made  shall be carried
forward and taken into account in any subsequent adjustment;  provided, further,
however,  that  adjustments  shall be required and made in  accordance  with the
provisions  of this Section 3 (other than this  Subsection  3(g)) not later than
such time as may be  required  in order to  preserve  the  tax-free  nature of a
distribution  to the Holder of this  Warrant or Common Stock  issuable  upon the
exercise  hereof.  All  calculations  under this  Section 3 shall be made to the
nearest cent or to the nearest  1/100th of a share, as the case may be. Anything
in this Section 3 to the contrary notwithstanding, the Company shall be entitled
to make such reductions in the Per Share

<PAGE>

Warrant  Price,  in addition to those  required by this  Section 3, as it in its
discretion  shall  deem to be  advisable  in  order  that  any  stock  dividend,
subdivision of shares or  distribution of rights to purchase stock or securities
convertible  or  exchangeable  for stock  hereafter  made by the  Company to its
stockholders shall not be taxable.

         (h)  Whenever  the Per Share  Warrant  Price is adjusted as provided in
this Section 3 and upon any  modification  of the rights of a Holder of Warrants
in accordance  with this Section 3, the Chief  Financial  Officer of the Company
shall promptly  prepare a certificate  setting forth the Per Share Warrant Price
and the number of Warrant  Shares  after such  adjustment  or the effect of such
modification  and a brief  statement of the facts  requiring such  adjustment or
modification  and the  manner of  computing  the same and  cause  copies of such
certificate  to be  mailed to the  Holders  of the  Warrants.  In the event of a
dispute  with  respect to any  adjustment  required  pursuant  to Section 3, the
Holder may appoint, at the Company's expense,  an independent  financial advisor
(e.g. an  investment  banking or  accounting  firm)reasonably  acceptable to the
Company to calculate such adjustment.  Such determination  shall be binding upon
the Holder and the Company.

         (i) If the Board of Directors of the Company shall declare any dividend
or other  distribution  with respect to the Common Stock, the Company shall mail
notice thereof to the Holders of the Warrants not less than 15 days prior to the
record date fixed for determining  stockholders  entitled to participate in such
dividend or other distribution.

         (j) If, as a result of an  adjustment  made pursuant to this Section 3,
the Holder of any Warrant  thereafter  surrendered  for  exercise  shall  become
entitled to receive  shares of two or more classes of capital stock or shares of
Common  Stock and other  capital  stock of the  Company,  the Board of Directors
(whose  determination  shall be  conclusive  and shall be described in a written
notice to the  Holder of any  Warrant  promptly  after  such  adjustment)  shall
determine  the  allocation  of the adjusted Per Share  Warrant  Price between or
among  shares or such  classes  of capital  stock or shares of Common  Stock and
other capital stock.

         4. FULLY PAID STOCK;  TAXES.  The Company agrees that the shares of the
Common  Stock  represented  by each and  every  certificate  of  Warrant  Shares
delivered  on the exercise of this  Warrant be validly  issued and  outstanding,
fully paid and nonassessable,  and not subject to preemptive rights or rights of
first refusal, and the Company will take all such actions as may be necessary to
assure that the par value or stated value, if any, per share of the Common Stock
is at all  times  equal to or less than the then Per Share  Warrant  Price.  The
Company further covenants and agrees that it will pay, when due and payable, any
and all Federal and state stamp,  original  issue or similar  taxes which may be
payable in respect of the issue of any Warrant Share or any certificate thereof.

         5. REGISTRATION UNDER SECURITIES ACT OF 1933.

         (a)  The  Company  shall  include  the  Warrant  Shares  on  the  Shelf
Registration  Statement  (as defined in the PPM) and the Holder shall  otherwise
have  the  registration  rights  set  forth  in  Section  5 of the  subscription
agreement (the "Subscription

<PAGE>

Agreement")  to be entered into between the purchasers of units (as described in
the PPM) and the Company. By acceptance of this Warrant,  the Holder agrees that
it shall have the same obligations, and otherwise comply with, the provisions in
such  Section 5 of the  Subscription  Agreement  to same  extent as if it were a
party  thereto.  To the extent  that no Final  Closing  Date (as  defined in the
Subscription Agreement) occurs or the Offering is terminated, the rights granted
to Holder hereunder to have its shares registered shall begin as of November 19,
1997 on the same terms as provided in Section 5 of the Subscription Agreement.

         (b) The  Company  agrees  that if,  at any  time and from  time to time
during the  Registration  Period,  the Board of Directors  of the Company  shall
authorize  the filing of a  registration  statement  under the Act  (other  than
pursuant to the Shelf  Registration  Statement) in connection  with the proposed
offer of any of its  securities  by it or any of its  stockholders,  the Company
will (i) promptly  notify each Holder of the Warrants and each holder of Warrant
Shares  that such  registration  statement  will be filed  and that the  Warrant
Shares which are then held, and/or may be acquired upon exercise of the Warrants
by the Holder and such holders will be included in such  registration  statement
at the  Holder's  and  such  holders'  request,  (ii)  cause  such  registration
statement  to cover all of such Common  Stock which it has been so  requested to
include,  (iii) use its best  efforts to cause such  registration  statement  to
become effective as soon as practicable and (iv) take all other action necessary
under any Federal or state law or  regulation of any  governmental  authority to
permit all such Common  Stock which it has been so  requested to include in such
registration  statement to be sold or otherwise  disposed of, and will  maintain
such  compliance  with each such  Federal  and state law and  regulation  of any
governmental  authority for the period necessary for the Holder and such Holders
to effect the proposed sale or other disposition.

         (c) Until all  Warrant  Shares  have  been  sold  under a  Registration
Statement or pursuant to Rule 144,  the Company  shall use its  reasonable  best
efforts to file with the Securities and Exchange  Commission all current reports
and the  information as may be necessary to enable the Holder to effect sales of
its shares in reliance upon Rule 144 promulgated under the Act.

         6. LIMITED TRANSFERABILITY.  This Warrant may not be sold, transferred,
assigned or  hypothecated by the Holder except in compliance with the provisions
of the Act and the applicable  state securities "blue sky" laws. The Company may
treat the registered Holder of this Warrant as he or it appears on the Company's
books at any time as the Holder for all  purposes.  The Company shall permit any
Holder of a Warrant or his duly authorized attorney, upon written request during
ordinary  business  hours,  to inspect and copy or make  extracts from its books
showing  the  registered  holders of  Warrants.  All  warrants  issued  upon the
transfer  or  assignment  of this  Warrant  will be dated  the same date as this
Warrant, and all rights of the holder thereof shall be identical to those of the
Holder.

         7. LOSS, ETC., OF WARRANT. Upon receipt of evidence satisfactory to the
Company of the loss,  theft,  destruction or mutilation of this Warrant,  and of
indemnity reasonably  satisfactory to the Company, if lost, stolen or destroyed,
and upon surrender and

<PAGE>

cancellation  of this  Warrant,  if  mutilated,  the Company  shall  execute and
deliver to the Holder a new Warrant of like date, tenor and denomination.

         8. WARRANT HOLDER NOT SHAREHOLDER. Except as otherwise provided herein,
this  Warrant does not confer upon the Holder any right to vote or to consent to
or receive  notice as a stockholder  of the Company,  as such, in respect of any
matters whatsoever,  or any other rights or liabilities as a stockholder,  prior
to the exercise hereof.

         9.  COMMUNICATION.  No notice or other communication under this Warrant
shall be  effective  unless,  but any  notice  or other  communication  shall be
effective  and shall be deemed to have been given if, the same is in writing and
is mailed by first-class mail, postage prepaid, addressed to:

such address as the Holder has designated in writing to the Company.

         10.  HEADINGS.  The headings of this  Warrant  have been  inserted as a
matter of convenience and shall not affect the construction hereof.

accordance  with the law of the State of New York without  giving  effect to the
principles of conflicts of law thereof.

                      WARRANT FOR THE PURCHASE OF SHARES OF
                                  COMMON STOCK

NO. [ ]                                                               [ ] SHARES


                  FOR VALUE RECEIVED, CONVERSION TECHNOLOGIES
INTERNATIONAL,  INC., a Delaware  corporation (the "COMPANY"),  hereby certifies
that [ ], or its permitted assigns, is entitled to purchase from the Company, at
any time or from time to time commencing on MAY 8, 1998, and prior to 5:00 P.M.,
New York City time, on MAY 8, 2003 (the "TERMINATION  DATE"), [ ] fully paid and
non-assessable  shares of the Common Stock,  $.00025 par value per share, of the
Company (the "Common  Stock") at an exercise  price equal to the  representative
closing  bid price of the Common  Stock on May 8,  1998,  which it is agreed and
acknowledged  to be equal to $1.00  per  share of Common  Stock  (the  "EXERCISE
PRICE").  (Hereinafter,  (i) said Common  Stock,  together with any other equity
securities  which  may be issued  by the  Company  with  respect  thereto  or in
substitution  therefor, is referred to as the "COMMON STOCK", (ii) the shares of
the  Common  Stock  purchasable   hereunder  or  under  any  other  Warrant  (as
hereinafter  defined)  are  referred  to as  the  "WARRANT  SHARES",  (iii)  the
aggregate purchase price payable for the Warrant Shares hereunder is referred to
as the "AGGREGATE WARRANT PRICE", (iv) the price payable for each of the Warrant
Shares  hereunder  is referred  to as the "PER SHARE  WARRANT  PRICE",  (v) this
Warrant,  all  similar  Warrants  issued  on the date  hereof  and all  warrants
hereafter  issued in exchange or  substitution  for this Warrant or such similar
Warrants are referred to as the  "WARRANTS"  and (vi) the holder of this Warrant
is  referred  to as the  "HOLDER"  and the holder of this  Warrant and all other
Warrants or Warrant  Shares issued upon the exercise of any Warrant are referred
to as the "HOLDERS").  The Aggregate Warrant Price is not subject to adjustment.
The Per Share Warrant Price is subject to adjustment as hereinafter provided; in
the event of any such adjustment, the number of Warrant Shares shall be adjusted
by dividing

<PAGE>

the Aggregate Warrant Price by the Per Share Warrant Price in effect immediately
after such adjustment.

1.        EXERCISE OF WARRANT.

         (a) This Warrant may be  exercised by the Holder,  in whole at any time
or in part  from  time to  time,  commencing  on May 8,  1998  and  prior to the
Termination Date:

               (i) by the surrender of this Warrant (with the  subscription form
          at  the  end  hereof  duly  executed)  at the  address  set  forth  in
          Subsection 10(a) hereof, together with proper payment of the Aggregate
          Warrant Price,  or the  proportionate  part thereof if this Warrant is
          exercised in part,  with payment for Warrant  Shares made by certified
          or official bank check payable to the order of the Company; or

               (ii) by the surrender of this Warrant (with the cashless exercise
          form at the end hereof duly  executed) (a "CASHLESS  EXERCISE") at the
          address set forth in Subsection  10(a) hereof.  Such  presentation and
          surrender  shall be deemed a waiver of the Holder's  obligation to pay
          the Aggregate Warrant Price, or the proportionate part thereof if this
          Warrant is exercised in part. In the event of a Cashless Exercise, the
          Holder shall  exchange  its Warrant for that number of Warrant  Shares
          subject  to such  Cashless  Exercise  multiplied  by a  fraction,  the
          numerator  of which shall be the  difference  between the then current
          Market  Price per share (as  hereinafter  defined) of Common Stock and
          the Per Share Warrant Price, and the denominator of which shall be the
          then current Market Price per share of Common Stock.  The then current
          market  price per share of the Common  Stock at any date (the  "MARKET
          PRICE")  shall be deemed to be the last sale price of the Common Stock
          on the business day prior to the date of the Cashless  Exercise or, in
          case no such reported sales take place on such day, the average of the
          last reported bid and asked prices of the Common Stock on such day, in
          either case on the principal national securities exchange on which the
          Common  Stock is  admitted  to trading or listed,  or if not listed or
          admitted to trading on any such exchange,  the representative  closing
          bid price of the Common Stock as reported by the NASDAQ Bulletin Board
          ("NASDAQ"),  or other  similar  organization  if  NASDAQ  is no longer
          reporting such  information,  or if not so available,  the fair market
          price of the Common Stock as  determined in good faith by the Board of
          Directors.

         (b) If  this  Warrant  is  exercised  in  part,  this  Warrant  must be
exercised  for a number of whole  shares of the  Common  Stock and the Holder is
entitled to receive a new Warrant  covering  the Warrant  Shares  which have not
been exercised and setting forth the proportionate part of the Aggregate Warrant
Price  applicable to such Warrant  Shares.  Upon surrender of this Warrant,  the
Company will (i) issue a certificate or  certificates  in the name of the Holder
for the largest  number of whole  shares of the Common Stock to which the Holder
shall be entitled  and, if this Warrant is  exercised  in whole,  in lieu of any
fractional share of the Common Stock to which the Holder shall be entitled,  pay
to the Holder cash in an amount equal to the fair value of such fractional share
(determined in such  reasonable  manner as the Board of Directors of the Company
shall determine), and (ii) deliver the other

<PAGE>

securities and properties  receivable upon the exercise of this Warrant, if any,
or the proportionate part thereof if this Warrant is exercised in part, pursuant
to the provisions of this Warrant.

         2. RESERVATION  OF WARRANT  SHARES;  LISTING.  The Company agrees that,
prior to the expiration of this Warrant,  the Company will at all times (a) have
authorized  and in  reserve,  and will keep  available,  solely for  issuance or
delivery upon the exercise of this  Warrant,  the shares of the Common Stock and
other  securities and  properties as from time to time shall be receivable  upon
the  exercise of this  Warrant,  free and clear of all  restrictions  on sale or
transfer,  except  for the  restrictions  on sale or  transfer  set forth in the
Securities Act of 1933, as amended (the "Act"),  and restrictions  created by or
on behalf of the Holder,  and free and clear of all preemptive rights and rights
of first  refusal and (b) when the  Company  prepares  and files a  registration
statement  covering the shares of Common Stock issued or issuable  upon exercise
of this Warrant with the  Securities and Exchange  Commission  (the "SEC") which
registration  statement  is declared  effective by the SEC under the Act and the
Company  lists its Common  Stock on any  national  securities  exchange or other
quotation system, it will use its reasonable best efforts to cause the shares of
Common Stock  subject to this Warrant to be listed on such exchange or quotation
system.

         3. PROTECTION AGAINST DILUTION.

         (a) If, at any time or from time to time after the date of  issuance of
this Warrant,  the Company shall issue or distribute to the holders of shares of
Common Stock evidence of its  indebtedness,  any other securities of the Company
or any cash,  property or other assets (excluding a subdivision,  combination or
reclassification, or dividend or distribution payable in shares of Common Stock,
referred to in  Subsection  3(b),  and also  excluding  cash  dividends  or cash
distributions  paid out of net profits  legally  available  therefor in the full
amount   thereof,   which  together  with  the  value  of  other  dividends  and
distributions  made substantially  concurrently  therewith or pursuant to a plan
which  includes  payment  thereof,  is  equivalent  to not  more  than 5% of the
Company's net worth) (any such non-excluded event being herein called a "SPECIAL
DIVIDEND"), the Per Share Warrant Price shall be adjusted by multiplying the Per
Share Warrant  Price then in effect by a fraction,  the numerator of which shall
be the then current  Market Price of the Common Stock less the fair market value
(as  determined  in good  faith  by the  Company's  Board of  Directors)  of the
evidence of indebtedness,  cash,  securities or property, or other assets issued
or distributed in such Special Dividend  applicable to one share of Common Stock
and the  denominator  of which  shall be the then  current  Market  Price of the
Common Stock.  An adjustment  made pursuant to this Subsection 3(a) shall become
effective immediately after the record date of any such Special Dividend.

         (b) In case the Company  shall  hereafter  (i) pay a dividend or make a
distribution on its capital stock in shares of Common Stock,  (ii) subdivide its
outstanding  shares  of Common  Stock  into a greater  number of  shares,  (iii)
combine its  outstanding  shares of Common Stock into a smaller number of shares
or (iv)  issue by  reclassification  of its  Common  Stock any shares of capital
stock of the Company,  the Per Share Warrant Price shall be adjusted to be equal
to a fraction, the numerator of which shall be the Aggregate

<PAGE>

Warrant  Price and the  denominator  of which  shall be the  number of shares of
Common Stock or other  capital  stock of the Company which the Holder would have
owned  immediately  following  such  action  had  such  Warrant  been  exercised
immediately  prior thereto.  An adjustment made pursuant to this Subsection 3(b)
shall  become  effective  immediately  after  the  record  date in the case of a
dividend  or  distribution  and shall  become  effective  immediately  after the
effective date in the case of a subdivision, combination or reclassification.

         (c)  Except as  provided  in  subsections  3(a) and  3(d),  in case the
Company  shall  hereafter  issue  or  sell  any  Common  Stock,  any  securities
convertible  into Common  Stock or any  rights,  options or warrants to purchase
Common Stock or securities  convertible  into Common  Stock,  in each case for a
price per share or entitling the holders  thereof to purchase  Common Stock at a
price per share  (determined by dividing (i) the total amount,  if any, received
or  receivable by the Company in  consideration  of the issuance or sale of such
securities  plus the total  consideration,  if any,  payable to the Company upon
exercise or conversion thereof (the "TOTAL CONSIDERATION") by (ii) the number of
additional  shares of Common Stock  issued,  sold or issuable  upon  exercise or
conversion of such securities)  which is less than the then current Market Price
of the Common Stock or the current Per Share Warrant Price in effect on the date
of such  issuance  or sale,  the Per Share  Warrant  Price  shall be adjusted by
multiplying  the Per Share  Warrant  Price  then in effect  by a  fraction,  the
numerator  of which  shall be (x) the sum of (A) the  number of shares of Common
Stock outstanding on the record date of such issuance or sale plus (B) the Total
Consideration  divided by either the current Market Price of the Common Stock or
the current Per Share Warrant Price,  whichever is greater,  and the denominator
of which shall be (y) the number of shares of Common  Stock  outstanding  on the
record  date of such  issuance  or sale plus the  maximum  number of  additional
shares of Common Stock  issued,  sold or issuable upon exercise or conversion of
such securities.

         (d) Except as otherwise provided herein, no adjustment in the Per Share
Warrant  Price shall be  required in the case of the  issuance by the Company of
(i) Common Stock  pursuant to the exercise or  conversion  of any Warrant or any
other options,  warrants or any convertible  securities currently outstanding or
outstanding  as a result of  securities  hereafter  issued;  provided,  that the
exercise  price or conversion  price at which such  securities  are exercised or
converted,  as the case may be,  is equal to the  exercise  price or  conversion
price in effect  as of the date of this  Warrant  or as of the date of  issuance
with respect to securities  hereafter issued (except for standard  anti-dilution
adjustments)  and (ii) shares of Common Stock  issued or sold  pursuant to stock
purchase or stock option plans or other similar  arrangements  that are approved
by the Company's Board of Directors.

         (e) In case of any capital  reorganization or reclassification,  or any
consolidation  or merger to which the  Company is a party other than a merger or
consolidation in which the Company is the continuing corporation,  or in case of
any sale or  conveyance  to another  entity of the property of the Company as an
entirety  or  substantially  as an  entirety,  or in the  case of any  statutory
exchange of securities with another corporation (including any exchange effected
in connection with a merger of a third corporation into the Company), the Holder
of this Warrant  shall have the right  thereafter  to receive on the exercise of
this Warrant the kind and amount of securities, cash or other property which the

<PAGE>

Holder would have owned or have been entitled to receive  immediately after such
reorganization,  reclassification,  consolidation,  merger,  statutory exchange,
sale or  conveyance  had this Warrant been  exercised  immediately  prior to the
effective date of such reorganization, reclassification,  consolidation, merger,
statutory  exchange,  sale or  conveyance  and in any such case,  if  necessary,
appropriate  adjustment  shall be made in the  application of the provisions set
forth in this Section 3 with respect to the rights and  interests  thereafter of
the  Holder of this  Warrant  to the end that the  provisions  set forth in this
Section 3 shall thereafter  correspondingly be made applicable, as nearly as may
reasonably  be,  in  relation  to any  shares  of stock or other  securities  or
property  thereafter  deliverable  on the  exercise of this  Warrant.  The above
provisions  of  this   subsection  3(e)  shall  similarly  apply  to  successive
reorganizations,    reclassifications,    consolidations,   mergers,   statutory
exchanges,  sales or  conveyances.  The  issuer of any  shares of stock or other
securities or property  thereafter  deliverable  on the exercise of this Warrant
shall be responsible  for all of the  agreements and  obligations of the Company
hereunder. Notice of any such reorganization,  reclassification,  consolidation,
merger,  statutory  exchange,  sale  or  conveyance  and of said  provisions  so
proposed  to be made,  shall be mailed to the Holders of the  Warrants  not less
than 30 days  prior to such  event.  A sale of all or  substantially  all of the
assets of the Company for a  consideration  consisting  primarily of  securities
shall be deemed a consolidation or merger for the foregoing purposes.

         (f) In case any event shall occur as to which the other  provisions  of
this Section 3 are not strictly  applicable  but as to which the failure to make
any adjustment would not fairly protect the purchase rights  represented by this
Warrant in accordance with the essential  intent and principles  hereof then, in
each such case,  the  Holders of Warrants  representing  the right to purchase a
majority of the Warrant Shares subject to all outstanding Warrants may appoint a
firm  of  independent  public   accountants  of  recognized   national  standing
reasonably  acceptable to the Company,  which shall give their opinion as to the
adjustment,  if  any,  on a basis  consistent  with  the  essential  intent  and
principles  established  herein,  necessary  to  preserve  the  purchase  rights
represented  by the  Warrants.  Upon receipt of such  opinion,  the Company will
promptly  mail a copy  thereof to the Holder of this  Warrant and shall make the
adjustments  described therein. The fees and expenses of such independent public
accountants shall be borne by the Company.

         (g) No  adjustment  in the Per Share  Warrant  Price  shall be required
unless such  adjustment  would require an increase or decrease of at least $0.05
per share of Common Stock;  provided,  however,  that any  adjustments  which by
reason of this  Subsection  3(g) are not  required  to be made  shall be carried
forward and taken into account in any subsequent adjustment.  provided, further,
however,  that  adjustments  shall be required and made in  accordance  with the
provisions  of this Section 3 (other than this  Subsection  3(g)) not later than
such time as may be  required  in order to  preserve  the  tax-free  nature of a
distribution  to the Holder of this  Warrant or Common Stock  issuable  upon the
exercise  hereof.  All  calculations  under this  Section 3 shall be made to the
nearest cent or to the nearest  1/100th of a share, as the case may be. Anything
in this Section 3 to the contrary notwithstanding, the Company shall be entitled
to make such  reductions  in the Per Share Warrant  Price,  in addition to those
required by this Section 3, as it in its  discretion  shall deem to be advisable
in order that any stock dividend, subdivision of shares or distribution of

<PAGE>

rights to purchase  stock or securities  convertible or  exchangeable  for stock
hereafter made by the Company to its stockholders shall not be taxable.
         (h)  Whenever  the Per Share  Warrant  Price is adjusted as provided in
this Section 3 and upon any  modification  of the rights of a Holder of Warrants
in accordance  with this Section 3, the Chief  Financial  Officer of the Company
shall promptly  prepare a certificate  setting forth the Per Share Warrant Price
and the number of Warrant  Shares  after such  adjustment  or the effect of such
modification  and a brief  statement of the facts  requiring such  adjustment or
modification  and the  manner of  computing  the same and  cause  copies of such
certificate  to be  mailed to the  Holders  of the  Warrants.  In the event of a
dispute  with  respect to any  adjustment  required  pursuant  to Section 3, the
Holder may appoint, at the Company's expense,  an independent  financial advisor
(e.g. an investment  banking or accounting  firm)  reasonably  acceptable to the
Company to calculate such adjustment.  Such determination  shall be binding upon
the Holder and the Company.

         (i) If the Board of Directors of the Company shall declare any dividend
or other  distribution  with respect to the Common Stock, the Company shall mail
notice thereof to the Holders of the Warrants not less than 15 days prior to the
record date fixed for determining  stockholders  entitled to participate in such
dividend or other distribution.

         (j) If, as a result of an  adjustment  made pursuant to this Section 3,
the Holder of any Warrant  thereafter  surrendered  for  exercise  shall  become
entitled to receive  shares of two or more classes of capital stock or shares of
Common  Stock and other  capital  stock of the  Company,  the Board of Directors
(whose  determination  shall be  conclusive  and shall be described in a written
notice to the  Holder of any  Warrant  promptly  after  such  adjustment)  shall
determine  the  allocation  of the adjusted Per Share  Warrant  Price between or
among  shares or such  classes  of capital  stock or shares of Common  Stock and
other capital stock.

         (k) To the extent that the Notes (as defined in the Line of Credit) are
not repaid by the  Maturity  Date (as  defined in the Note),  then the  Exercise
Price of this  Warrant  thereafter  shall  equal  the  lesser  of:  (a) the then
Exercise  Price on such date (subject to adjustment as contained this Section 3)
and (b) the Market Price on the date of exercise.

         4. FULLY PAID STOCK;  TAXES.  The Company agrees that the shares of the
Common  Stock  represented  by each and  every  certificate  of  Warrant  Shares
delivered  on the exercise of this  Warrant be validly  issued and  outstanding,
fully paid and nonassessable,  and not subject to preemptive rights or rights of
first refusal, and the Company will take all such actions as may be necessary to
assure that the par value or stated value, if any, per share of the Common Stock
is at all  times  equal to or less than the then Per Share  Warrant  Price.  The
Company further covenants and agrees that it will pay, when due and payable, any
and all Federal and state stamp,  original  issue or similar  taxes which may be
payable in respect of the issue of any Warrant Share or any certificate thereof.

         5. REGISTRATION UNDER SECURITIES ACT OF 1933.

         (a) The  Company  agrees  that if,  at any  time and from  time to time
during the  Registration  Period,  the Board of Directors  of the Company  shall
authorize  the filing of a  registration  statement  under the Act (other than a
registration  statement  on Form S-8,  Form S- 4 or any other form that does not
include  substantially  the same  information as would be required in a form for
the general registration of securities) in connection with the proposed offer of
any of its  securities  by it or any of its  stockholders,  the Company will (i)
promptly  notify each Holder of the Warrants  and each holder of Warrant  Shares
that such registration statement will be filed and that the Warrant Shares which
are then held,  and/or may be  acquired  upon  exercise  of the  Warrants by the
Holder and such holders will be included in such  registration  statement at the
Holder's and such holders' request,  (ii) cause such  registration  statement to
cover all of such Common Stock which it has been so requested to include,  (iii)
use its best efforts to cause such registration statement to become effective as
soon as practicable  and (iv) take all other action  necessary under any Federal
or state law or  regulation  of any  governmental  authority  to permit all such
Common  Stock  which it has been so  requested  to include in such  registration
statement to be sold or otherwise disposed of, and will maintain such compliance
with  each  such  Federal  and  state  law and  regulation  of any  governmental
authority for the period necessary for the Holder and such Holders to effect the
proposed sale or other disposition.

         (b) Until all  Warrant  Shares  have  been  sold  under a  Registration
Statement or pursuant to Rule 144,  the Company  shall use its  reasonable  best
efforts to file with the Securities and Exchange  Commission all current reports
and the  information as may be necessary to enable the Holder to effect sales of
its shares in reliance upon Rule 144 promulgated under the Act.

         6. LIMITED TRANSFERABILITY.  This Warrant may not be sold, transferred,
assigned or  hypothecated by the Holder except in compliance with the provisions
of the Act and the applicable  state securities "blue sky" laws. The Company may
treat the registered Holder of this Warrant as he or it appears on the Company's
books at any time as the Holder for all  purposes.  The Company shall permit any
Holder of a Warrant or his duly authorized attorney, upon written request during
ordinary  business  hours,  to inspect and copy or make  extracts from its books
showing  the  registered  holders of  Warrants.  All  warrants  issued  upon the
transfer  or  assignment  of this  Warrant  will be dated  the same date as this
Warrant, and all rights of the holder thereof shall be identical to those of the
Holder.

         7. LOSS, ETC., OF WARRANT. Upon receipt of evidence satisfactory to the
Company of the loss,  theft,  destruction or mutilation of this Warrant,  and of
indemnity reasonably  satisfactory to the Company, if lost, stolen or destroyed,
and upon surrender and cancellation of this Warrant,  if mutilated,  the Company
shall  execute and  deliver to the Holder a new Warrant of like date,  tenor and
denomination.

         8. WARRANT HOLDER NOT SHAREHOLDER. Except as otherwise provided herein,
this  Warrant does not confer upon the Holder any right to vote or to consent to
or receive  notice as a stockholder  of the Company,  as such, in respect of any
matters whatsoever,  or any other rights or liabilities as a stockholder,  prior
to the exercise hereof.

<PAGE>

         9. MODIFICATION.  This Agreement may not be modified, amended or waived
in any manner  except by an instrument  in writing  signed by Paramount  Capital
Asset  Management,  Inc. [ ], and the  Company.  The  waiver by either  party of
compliance  with any  provision  of this  Agreement by the other party shall not
operate  or be  construed  as a  waiver  of such  party of a  provision  of this
Agreement.

         10. COMMUNICATION.  No notice or other communication under this Warrant
shall be  effective  unless,  but any  notice  or other  communication  shall be
effective  and shall be deemed to have been given if, the same is in writing and

such address as the Holder has designated in writing to the Company.

         11.  HEADINGS.  The headings of this  Warrant  have been  inserted as a
matter of convenience and shall not affect the construction hereof.

         12.  APPLICABLE LAW. This Warrant shall be governed by and construed in
accordance  with the law of the State of New York without  giving  effect to the
principles of conflicts of law thereof.

No. 1                                                                 [ ] Shares


         FOR VALUE  RECEIVED,  CONVERSION  TECHNOLOGIES  INTERNATIONAL,  INC., a
Delaware corporation (the "COMPANY"), hereby certifies that [ ], its designee or
its permitted  assigns is entitled to purchase from the Company,  at any time or
from time to time  commencing  on June 8, 1998 and prior to 5:00 P.M.,  New York
City time, on June 8, 2008, [ ] fully paid and non-assessable shares of Series A
Convertible  Preferred  Stock,  $.001 par value per share, of the Company for an
aggregate  purchase  price of $[ ] (computed  on the basis of $11.00 per share).
Hereinafter,  (i) said Series A Convertible  Preferred Stock,  together with any
other equity  securities which may be issued by the Company with respect thereto
(other than on conversion thereof) or in substitution  therefor,  is referred to
as the "PREFERRED  STOCK",  (ii) the Common Stock, $.001 par value per share, of
the Company,  into which the Preferred Stock is  convertible,  is referred to as
the  "COMMON  STOCK",  (iii)  the  shares  of the  Preferred  Stock  purchasable
hereunder or under any other Warrant (as hereinafter defined) are referred to as
the "WARRANT SHARES",  (iv) the shares of Common Stock purchasable  hereunder or
under any other Warrant (as hereinafter defined) following the conversion of all
shares of  Preferred  Stock into  Common  Stock and each  share of Common  Stock
receivable  upon  the  conversion  of the  Warrant  Shares  receivable  upon the
exercise of this Warrant are  referred to as the  "CONVERSION  SHARES",  (v) the
aggregate  purchase  price  payable  for the  Warrant  Shares or the  Conversion
Shares,  as the case may be, hereunder is referred to as the "AGGREGATE  WARRANT
PRICE",  (vi)  the  price  payable  (initially  $11.00  per  share,  subject  to
adjustment) for each of the Warrant Shares or the Conversion Shares, as the case
may be,  hereunder is referred to as the "PER SHARE WARRANT  PRICE",  (vii) this
Warrant,  all  similar  Warrants  issued  on the date  hereof  and all  warrants
hereafter  issued in exchange or  substitution  for this Warrant or such similar
Warrants are referred to as the "WARRANTS", (viii) the holder of this Warrant is

<PAGE>

the  "HOLDER"  and the holder of this  Warrant and all other  Warrants,  Warrant
Shares and  Conversion  Shares are referred to as the  "HOLDERS"  and Holders of
more than fifty percent (50%) of the  outstanding  Warrants,  Warrant Shares and
Conversion Shares are referred to as the "MAJORITY OF THE HOLDERS") and (ix) the
then Current Market Price per share (the "CURRENT MARKET PRICE") shall be deemed
to be the last sale price of the Common  Stock on the  trading day prior to such
date or, in case no such  reported  sales take place on such day, the average of
the last  reported  bid and asked  prices of the  Common  Stock on such day,  in
either case on the principal  national  securities  exchange on which the Common
Stock is admitted to trading or listed,  or if not listed or admitted to trading
on any such exchange,  the representative closing sale price of the Common Stock
as reported by the National  Association of Securities  Dealers,  Inc. Automated
Quotations  System  ("NASDAQ"),  or other similar  organization  if Nasdaq is no
longer  reporting such  information,  or, if the Common Stock is not reported on
Nasdaq,   the  high  per  share  sale   price  for  the  Common   Stock  in  the
over-the-counter  market as reported by the National Quotation Bureau or similar
organization,  or if not so available, the fair market value of the Common Stock
as determined in good faith by the Board of Directors.  The then "CURRENT MARKET
PRICE PER SHARE OF PREFERRED  STOCK"  shall equal the then Current  Market Price
multiplied by the then effective  "conversion  rate" (as defined and used in the
Certificate  of  Designation  for the Preferred  Stock) or if the Current Market
Price is not so  available,  the fair  market  value of the  Preferred  Stock as
determined in good faith by agreement  among the Majority of the Holders and the
Company's  Board of  Directors.  The  Aggregate  Warrant Price is not subject to
adjustment.  The Per Share Warrant Price is subject to adjustment as hereinafter
provided;  in the event of any such adjustment,  the number of Warrant Shares or
Conversion Shares, as the case may be, deliverable upon exercise of this Warrant
shall be adjusted  by  dividing  the  Aggregate  Warrant  Price by the Per Share
Warrant Price in effect  immediately  after such adjustment.  The Warrants shall
not be  subject  to  redemption  by the  Company  nor will they be  callable  or
mandatorily convertible by the Company.

         1. EXERCISE OF WARRANT.

         (a) This Warrant may be exercised, in whole at any time or in part from
time to time,  commencing on June 8, 1998 and prior to 5:00 P.M.,  New York City
time, on June 8, 2008 by the Holder:

         (i) by the surrender of this Warrant (with the subscription form at the
end hereof  duly  executed)  at the address  set forth in Section  9(a)  hereof,
together  with  proper  payment  of  the  Aggregate   Warrant   Price,   or  the
proportionate  part thereof if this  Warrant is exercised in part,  with payment
for Warrant Shares or Conversion  Shares,  as the case may be, made by certified
or official bank check payable to the order of the Company; or

         (ii) by the surrender of this Warrant (with the cashless  exercise form
at the end hereof duly  executed)  (a  "CASHLESS  EXERCISE")  at the address set
forth in Section 9(a) hereof.  Such presentation and surrender shall be deemed a
waiver of the Holder's  obligation to pay the Aggregate  Warrant  Price,  or the
proportionate part


<PAGE>

thereof  if this  Warrant  is  exercised  in part.  In the  event of a  Cashless
Exercise,  the Holder  shall  exchange  its  Warrant  for that number of Warrant
Shares  or  Conversion  Shares,  as the case may be,  subject  to such  Cashless
Exercise  multiplied  by a  fraction,  the  numerator  of  which  shall  be  the
difference  between the then Current  Market Price Per Share of Preferred  Stock
(or the Current Market Price if exercised  after the Conversion Date (as defined
below)) and the Per Share Warrant Price,  and the  denominator of which shall be
the then  Current  Market  Price Per Share of  Preferred  Stock (or the  Current
Market Price if exercised  after the Conversion  Date (as defined  below)).  For
purposes of any  computation  under this Section 1(a),  the then Current  Market
Price shall be based on the trading day prior to the Cashless Exercise.

         (iii)  by  the  surrender  of  this  Warrant  (with  the   subscription
(promissory note) form at the end hereof duly executed) at the address set forth
in Subsection 9(a) hereof,  together with the  presentation of a promissory note
made  payable  to the  corporation,  duly  executed  and in the  form at the end
hereof. Such promissory note shall be secured by the securities  underlying this
Warrant,  which shall be held in  safe-keeping  by the Company as collateral for
such indebtedness.

         (b) If  this  Warrant  is  exercised  in  part,  this  Warrant  must be
exercised  for a number of whole shares of the Preferred  Stock,  (or the Common
Stock following the Conversion Date) and the Holder is entitled to receive a new
Warrant  covering the Warrant Shares or Conversion  Shares,  as the case may be,
which have not been  exercised and setting forth the  proportionate  part of the
Aggregate Warrant Price applicable to such Warrant Shares or Conversion  Shares,
as the case may be. Upon surrender of this Warrant, the Company will (i) issue a
certificate or  certificates in the name of the Holder for the largest number of
whole  shares  of the  Preferred  Stock  (or  the  Common  Stock  following  the
Conversion  Date) to which the Holder shall be entitled  and, if this Warrant is
exercised in whole,  in lieu of any fractional  share of the Preferred Stock (or
the Common Stock  following  the  Conversion  Date) to which the Holder shall be
entitled,  pay to the Holder  cash in an amount  equal to the fair value of such
fractional share (determined in such reasonable manner as the Board of Directors
of the Company  shall  determine),  and (ii)  deliver the other  securities  and
properties  receivable upon the exercise of this Warrant,  or the  proportionate
part thereof if this Warrant is exercised in part, pursuant to the provisions of
this Warrant;  provided,  however that if this Warrant is exercised  pursuant to
paragraph  1(a)(iii),  the Company  will issue but shall not deliver such shares
until such time as the promissory  note and all accrued  interest  thereon shall
have been paid in full.

         (c) If this  Warrant  is  exercised  on or after  the date on which all
shares of Preferred  Stock have been  converted into shares of Common Stock (the
"Conversion  Date"),  then this Warrant shall be exercisable only for Conversion
Shares,  each at the then  applicable  Per Share  Warrant Price  (including  any
adjustment pursuant to Section 3(f) below).

         2. RESERVATION OF WARRANT SHARES AND CONVERSION  SHARES;  LISTING.  The
Company agrees that, prior to the expiration of this Warrant,  the Company shall
at all times (a) have  authorized  and in  reserve,  and shall  keep  available,
solely for issuance and


<PAGE>

delivery  upon the exercise of this Warrant,  the shares of the Preferred  Stock
and other  securities  and  properties  as from time to time shall be receivable
upon the exercise of this Warrant, free and clear of all restrictions on sale or
transfer,  other than under Federal or state securities laws, and free and clear
of all  preemptive  rights and rights of first  refusal  and (b)  subject to the
Company's  obligation  to  increase  the number of  authorized  shares of Common
Stock,  as described  in the  Confidential  Term Sheet dated August 8, 1997,  as
supplemented  and  amended,  have  authorized  and in  reserve,  and shall  keep
available, solely for issuance or delivery upon conversion of the Warrant Shares
or the  exercise of this  Warrant for  Conversion  Shares,  the shares of Common
Stock  and  other  securities  and  properties  as from  time to time  shall  be
receivable upon such  conversion,  free and clear of all restrictions on sale or
transfer,  other than under Federal or state securities laws, and free and clear
of all  preemptive  rights and rights of first  refusal;  and (c) if the Company
hereafter  lists its Common  Stock on any  national  securities  exchange or the
Nasdaq  National  Market or the Nasdaq  SmallCap  Market use its best efforts to
keep the Conversion  Shares  authorized for listing on such exchange upon notice
of issuance.

         3. PROTECTION AGAINST DILUTION.

         (a) If,  at any  time or from  time  to  time  after  the  date of this
Warrant,  the  Company  shall  issue or  distribute  to the holders of shares of
Preferred  Stock  evidence  of its  indebtedness,  any other  securities  of the
Company  or any  cash,  property  or  other  assets  (excluding  a  subdivision,
combination or  reclassification,  or dividend or distribution payable in shares
of  Preferred  Stock,  referred  to in Section  3(b),  and also  excluding  cash
dividends  or cash  distributions  paid  out of net  profits  legally  available
therefor in the full amount  thereof (any such  non-excluded  event being herein
called a "SPECIAL DIVIDEND")),  the Per Share Warrant Price shall be adjusted by
multiplying  the Per Share  Warrant  Price  then in effect  by a  fraction,  the
numerator  of which  shall be the then  Current  Market  Price  Per Share of the
Preferred  Stock in effect on the record date of such  issuance or  distribution
less the fair market value (as  determined in good faith by the Company's  Board
of Directors) of the evidence of indebtedness,  cash, securities or property, or
other assets issued or  distributed in such Special  Dividend  applicable to one
share of Preferred  Stock and the denominator of which shall be the then Current
Market  Price Per Share of the  Preferred  Stock in effect on the record date of
such issuance or  distribution.  An adjustment  made pursuant to this Subsection
3(a)  shall  become  effective  immediately  after the  record  date of any such
Special Dividend.

         (b) In case the Company  shall  hereafter  (i) pay a dividend or make a
distribution on its capital stock in shares of Preferred  Stock,  (ii) subdivide
its outstanding shares of Preferred Stock into a greater number of shares, (iii)
combine  its  outstanding  shares of  Preferred  Stock into a smaller  number of
shares or (iv) issue by  reclassification  of its Preferred  Stock any shares of
capital stock of the Company (other than the Conversion  Shares),  the Per Share
Warrant  Price shall be adjusted to be equal to a  fraction,  the  numerator  of
which shall be the Aggregate Warrant Price and the denominator of which shall be
the number of shares of Preferred  Stock or other  capital  stock of the Company
which he would have owned  immediately  following  such action had such  Warrant
been exercised  immediately  prior thereto.  An adjustment made pursuant to this
Subsection 3(b) shall


<PAGE>

become effective  immediately after the record date in the case of a dividend or
distribution and shall become effective  immediately after the effective date in
the case of a subdivision, combination or reclassification.

         (c) Except as provided in Subsections  3(a), 3(b) and 3(d), in case the
Company  shall  hereafter  issue or sell any  Preferred  Stock,  any  securities
convertible into Preferred  Stock,  any rights,  options or warrants to purchase
Preferred Stock or any securities convertible into Preferred Stock, in each case
for a price per share or  entitling  the holders  thereof to purchase  Preferred
Stock at a price per share (determined by dividing (i) the total amount, if any,
received or receivable by the Company in  consideration  of the issuance or sale
of such securities plus the total consideration,  if any, payable to the Company
upon  exercise or  conversion  thereof (the "TOTAL  CONSIDERATION")  by (ii) the
number of additional  shares of Preferred  Stock  issued,  sold or issuable upon
exercise or  conversion of such  securities)  which is less than either the then
Current Market Price Per Share of Preferred  Stock in effect on the date of such
issuance or sale or the Per Share  Warrant  Price,  the Per Share  Warrant Price
shall be adjusted as of the date of such issuance or sale by multiplying the Per
Share Warrant  Price then in effect by a fraction,  the numerator of which shall
be (x) the sum of (A) the number of shares of Preferred Stock outstanding on the
record date of such issuance or sale plus (B) the Total Consideration divided by
the Current  Market  Price Per Share of the  Preferred  Stock or the current Per
Share Warrant Price, whichever is greater, and the denominator of which shall be
(y) the number of shares of Preferred  Stock  outstanding  on the record date of
such issuance or sale plus the maximum number of additional  shares of Preferred
Stock issued, sold or issuable upon exercise or conversion of such securities.

         (d) No  adjustment  in the Per Share Warrant Price shall be required in
the case of the issuance by the Company of  Preferred  Stock (i) pursuant to the
exercise of any Warrant or (ii) pursuant to the exercise of any stock options or
warrants  currently  outstanding  or  securities  issued  after the date  hereof
pursuant to any Company benefit plan.

         (e) In case of any capital  reorganization or reclassification,  or any
consolidation  or merger to which the  Company is a party other than a merger or
consolidation in which the Company is the continuing corporation,  or in case of
any sale or  conveyance  to another  entity of the property of the Company as an
entirety  or  substantially  as a  entirety,  or in the  case  of any  statutory
exchange of securities with another corporation (including any exchange effected
in connection with a merger of a third corporation into the Company), the Holder
of this Warrant  shall have the right  thereafter  to receive on the exercise of
this Warrant the kind and amount of securities, cash or other property which the
Holder would have owned or have been entitled to receive  immediately after such
reorganization,  reclassification,  consolidation,  merger,  statutory exchange,
sale or  conveyance  had this Warrant been  exercised  immediately  prior to the
effective date of such reorganization, reclassification,  consolidation, merger,
statutory  exchange,  sale or  conveyance  and in any such case,  if  necessary,
appropriate  adjustment  shall be made in the  application of the provisions set
forth in this Section 3 with respect to the rights and  interests  thereafter of
the  Holder of this  Warrant  to the end that the  provisions  set forth in this
Section 3 shall thereafter  correspondingly be made applicable, as nearly as may
reasonably be, in


<PAGE>

relation  to any  shares of stock or other  securities  or  property  thereafter
deliverable  on the  exercise  of this  Warrant.  The above  provisions  of this
Section   3(e)   shall   similarly   apply   to   successive    reorganizations,
reclassifications,   consolidations,  mergers,  statutory  exchanges,  sales  or
conveyances.  The  Company  shall  require  the issuer of any shares of stock or
other  securities  or property  thereafter  deliverable  on the exercise of this
Warrant to be  responsible  for all of the  agreements  and  obligations  of the
Company  hereunder.   Notice  of  any  such  reorganization,   reclassification,
consolidation,  merger,  statutory  exchange,  sale  or  conveyance  and of said
provisions  so  proposed  to be made,  shall be  mailed  to the  Holders  of the
Warrants  not less than thirty  (30) days prior to such event.  A sale of all or
substantially  all of the assets of the Company for a  consideration  consisting
primarily  of  securities  shall be deemed a  consolidation  or  merger  for the
foregoing purposes.

         (f) Upon the  Conversion  Date,  the Per Share  Warrant  Price shall be
adjusted  to be  equal  to a  fraction,  the  numerator  of  which  shall be the
Aggregate  Warrant  Price and the  denominator  of which  shall be the number of
shares of Common Stock or other  capital  stock of the Company  which the Holder
would have owned  immediately  following  such  conversion had this Warrant been
exercised for  Preferred  Stock  (assuming a cash  exercise)  immediately  prior
thereto.

         (g) No  adjustment  in the Per Share  Warrant  Price  shall be required
unless such  adjustment  would require an increase or decrease of at least $0.05
per share of Preferred Stock;  provided,  however, that any adjustments which by
reason of this  Subsection  3(g) are not  required  to be made  shall be carried
forward and taken into account in any subsequent adjustment;  provided, further,
however,  that  adjustments  shall be required and made in  accordance  with the
provisions  of this Section 3 (other than this  Subsection  3(g)) not later than
such time as may be  required  in order to  preserve  the  tax-free  nature of a
distribution  to the Holder of this Warrant or Preferred Stock issuable upon the
exercise  hereof.  All  calculations  under this  Section 3 shall be made to the
nearest cent or to the nearest  1/100th of a share, as the case may be. Anything
in this Section 3 to the contrary notwithstanding, the Company shall be entitled
to make such  reductions  in the Per Share Warrant  Price,  in addition to those
required by this Section 3, as it in its  discretion  shall deem to be advisable
in order  that any stock  dividend,  subdivision  of shares or  distribution  of
rights to purchase  stock or securities  convertible or  exchangeable  for stock
hereafter made by the Company to its stockholders shall not be taxable.

         (h)  Whenever  the Per Share  Warrant  Price is adjusted as provided in
this Section 3 and upon any  modification  of the rights of a Holder of Warrants
in accordance  with this Section 3, the Company shall  promptly  prepare a brief
statement of the facts requiring such adjustment or modification  and the manner
of computing the same and cause copies of such  certificate  to be mailed to the
Holders of the  Warrants.  The Company may, but shall not be obligated to unless
requested by a Majority of the Holders, obtain, at its expense, a certificate of
a firm of independent public accountants of recognized  standing selected by the
Board of  Directors  (who may be the regular  auditors of the  Company)  setting
forth the Per Share Warrant Price and the number of Warrant Shares or Conversion
Shares,  as the  case  may be,  after  such  adjustment  or the  effect  of such
modification, a brief statement


<PAGE>

of the  facts  requiring  such  adjustment  or  modification  and the  manner of
computing  the same and  cause  copies of such  certificate  to be mailed to the
Holders of the Warrants.

         (i) If the Board of Directors of the Company shall declare any dividend
or other  distribution with respect to the Preferred Stock or Common Stock other
than a cash  distribution  out of earned surplus,  the Company shall mail notice
thereof to the Holders of the  Warrants not less than ten (10) days prior to the
record date fixed for determining  stockholders  entitled to participate in such
dividend or other distribution.

         (j) If, as a result of an  adjustment  made pursuant to this Section 3,
the Holder of any Warrant  thereafter  surrendered  for  exercise  shall  become
entitled to receive  shares of two or more classes of capital stock or shares of
Preferred  Stock and other capital stock of the Company,  the Company's Board of
Directors (whose  determination  shall be conclusive and shall be described in a
written  notice to the Holder of any  Warrant  promptly  after such  adjustment)
shall  determine the  allocation of the adjusted Per Share Warrant Price between
or among  shares or such classes of capital  stock or shares of Preferred  Stock
and other capital stock.

         (k) For  purposes of the  anti-dilution  protection  contained  in this
Section 3, at all times  following  the  conversion  of all shares of  Preferred
Stock into shares of Common Stock,  the term Preferred Stock shall be read to be
Common Stock,  context  permitting,  so that the  anti-dilution  provisions will
continue to protect the purchase  rights  represented  by this Warrant after the
conversion of all the Preferred  Stock into the Common Stock in accordance  with
the essential  intent and principles of this Section 3 (it being understood that
prior to such conversion,  the  anti-dilution  provisions of the Preferred Stock
shall protect the Holder from dilution of the Common Stock).

         (l) Upon the expiration of any rights, options,  warrants or conversion
privileges,  if such shall not have been exercised, the number of Warrant Shares
purchasable  upon exercise of this  Warrant,  to the extent this Warrant has not
then been  exercised,  shall,  upon such  expiration,  be  readjusted  and shall
thereafter be such as they would have been had they been originally adjusted (or
had the original adjustment not been required,  as the case may be) on the basis
of (A) the fact that Preferred  Stock, if any,  actually issued or sold upon the
exercise of such rights, options, warrants or conversion privileges, and (B) the
fact that such shares of Preferred  Stock,  if any,  were issued or sold for the
consideration  actually  received by the  Company  upon such  exercise  plus the
consideration,  if any, actually received by the Company for the issuance,  sale
or grant of all such rights, options,  warrants or conversion privileges whether
or not exercised;  provided,  however,  that no such readjustment shall have the
effect of decreasing the number of Conversion  Shares  purchasable upon exercise
of this Warrant by an amount in excess of the amount of the adjustment initially
made in respect of the issuance, sale or grant of such rights, options, warrants
or conversion privileges.

         4. FULLY PAID  STOCK;  TAXES.  The  Company  agrees  that the shares of
Preferred  Stock  represented by each and every  certificate  for Warrant Shares
delivered  on the  exercise  of this  Warrant  and the  shares of  Common  Stock
delivered upon the conversion of


<PAGE>

the Warrant  Shares or the exercise of this Warrant  following the conversion of
all shares of  Preferred  Stock  into  Common  Stock,  shall at the time of such
delivery, be validly issued and outstanding,  fully paid and nonassessable,  and
not subject to  preemptive  rights or rights of first  refusal,  and the Company
will take all such  actions as may be  necessary to assure that the par value or
stated value,  if any, per share of the Preferred  Stock and the Common Stock is
at all times equal to or less than the then Per Share Warrant Price. The Company
further covenants and agrees that it will pay, when due and payable, any and all
Federal and state stamp, original issue or similar taxes which may be payable in
respect of the issue of any Warrant Share,  Conversion  Share or any certificate
thereof to the extent  required  because of the  issuance by the Company of such
security.

         5. REGISTRATION UNDER SECURITIES ACT OF 1933. (a) The Holder shall with
respect to the  Conversion  Shares only,  have the right to  participate  in the
registration rights granted to purchasers of Preferred Stock pursuant to Article
5 of the subscription  agreements (the "Subscription  Agreements")  between such
purchasers  and the Company  that were  entered  into at the time of the initial
sale by the Company of the Preferred  Stock. By acceptance of this Warrant,  the
Holder  agrees to comply with the  provisions  in Article 5 of the  Subscription
Agreement to same extent as if it were a party thereto.

         (b) Until all  Conversion  Shares  have been sold under a  Registration
Statement  or  pursuant  to Rule 144  ("Rule  144")  as  promulgated  under  the
Securities Act of 1933, as amended (the "Securities Act"), the Company shall use
its reasonable best efforts to file with the Securities and Exchange  Commission
all current reports and the information as may be necessary to enable the Holder
to effect sales of its shares in reliance  upon Rule 144  promulgated  under the
Act.

         6. INVESTMENT INTENT; LIMITED TRANSFERABILITY.

         (a)  The  Holder  represents,   by  accepting  this  Warrant,  that  it
understands  that this Warrant and any  securities  obtainable  upon exercise of
this Warrant or upon  conversion of such securities have not been registered for
sale under  Federal or state  securities  laws and are being offered and sold to
the Holder pursuant to one or more exemptions from the registration requirements
of such  securities  laws. In the absence of an effective  registration  of such
securities or an exemption therefrom, any certificates for such securities shall
bear the legend set forth on the first page hereof.  The Holder understands that
it must  bear  the  economic  risk of its  investment  in this  Warrant  and any
securities  obtainable  upon exercise of this Warrant or upon conversion of such
securities for an indefinite period of time, as this Warrant and such securities
have not been  registered  under Federal or state  securities laws and therefore
cannot  be sold  unless  subsequently  registered  under  such  laws,  unless an
exemption from such registration is available.

         (b) The Holder,  by his  acceptance  of its Warrant,  represents to the
Company  that it is  acquiring  this  Warrant and will  acquire  any  securities
obtainable  upon exercise of this Warrant for its own account for investment and
not with a view to, or for sale in connection with, any distribution  thereof in
violation of the  Securities  Act of 1933,  as amended  (the "Act").  The Holder
agrees that this Warrant and any such securities will not


<PAGE>

be sold or  otherwise  transferred  unless  (i) a  registration  statement  with
respect to such  transfer is effective  under the Act and any  applicable  state
securities  laws or (ii) such sale or transfer  is made  pursuant to one or more
exemptions from the Act.

         (c) This Warrant may not be sold, transferred, assigned or hypothecated
for six (6) months  from the date hereof  except (i) to any firm or  corporation
that succeeds to all or substantially all of the business of Paramount  Capital,
Inc., (ii) to any of the officers, employees, associates or affiliated companies
of Paramount  Capital,  Inc., or of any such successor  firm,  (iii) to any NASD
member participating in the Offering or any officer or employee of any such NASD
member or (iv) in the case of an individual,  pursuant to such individual's last
will  and  testament  or  the  laws  of  descent  and  distribution,  and  is so
transferable  only  upon the  books of the  Company  which it shall  cause to be
maintained for such purpose. The Company may treat the registered Holder of this
Warrant as he or it appears on the Company's books at any time as the Holder for
all  purposes.  The  Company  shall  permit  any Holder of a Warrant or its duly
authorized  attorney,  upon written request during  ordinary  business hours, to
inspect and copy or make extracts from its books showing the registered  holders
of Warrants. All Warrants issued upon the transfer or assignment of this Warrant
will be dated  the same  date as this  Warrant,  and all  rights  of the  holder
thereof shall be identical to those of the Holder.

         7. LOSS, ETC., OF WARRANT. Upon receipt of evidence satisfactory to the
Company of the loss,  theft,  destruction or mutilation of this Warrant,  and of
indemnity reasonably  satisfactory to the Company, if lost, stolen or destroyed,
and upon surrender and cancellation of this Warrant,  if mutilated,  the Company
shall execute and deliver to the Holder,  a new Warrant of like date,  tenor and
denomination.

         8. WARRANT  HOLDER NOT  STOCKHOLDER.  This Warrant does not confer upon
the Holder any right to vote or to consent to or receive notice as a stockholder
of the  Company,  as such,  in respect of any matters  whatsoever,  or any other
rights or  liabilities  as a  stockholder,  prior to the exercise  hereof;  this
Warrant does, however, require certain notices to Holders as set forth herein.

         9.  COMMUNICATION.  No notice or other communication under this Warrant
shall be  effective  unless,  but any  notice  or other  communication  shall be
effective  and shall be deemed to have been given if, the same is in writing and
is mailed by first-class mail, postage prepaid, addressed to:

         (a) the Company at Conversion  Technologies  International,  Inc., 3452
Lake Lynda Drive, Suite 280, Orlando, Florida 32817, Attn: President, or at such
other address as the Company has designated in writing to the Holder, or

         (b) the  Holder at c/o  Paramount  Capital  Incorporated,  787  Seventh
Avenue,  New York,  New York 10019,  or at other such  address as the Holder has
designated in writing to the Company.


<PAGE>

         10.  HEADINGS.  The headings of this  Warrant  have been  inserted as a
matter of convenience and shall not affect the construction hereof.

         11.  APPLICABLE LAW. This Warrant shall be governed by and construed in
accordance  with the law of the State of New York without  giving  effect to the
principles of conflicts of law thereof.

         12.  AMENDMENT,  WAIVER,  ETC.  Except as  expressly  provided  herein,
neither this Warrant nor any term hereof may be amended,  waived,  discharged or
terminated other than by a written  instrument  signed by the party against whom
enforcement of any such amendment,  waiver,  discharge or termination is sought;
provided, however, that any provisions hereof may be amended, waived, discharged
or  terminated  upon the written  consent of the Company and the Majority of the
Holders of the Warrants only.

                                 PROMISSORY NOTE


$[   ]                                                        NEW YORK, NEW YORK
                                                              [           ]

         [WARRANTHOLDER]  ("Borrower"),  for value received,  hereby promises to
pay to the order of CONVERSION TECHNOLOGIES  INTERNATIONAL,  INC. (together with
any such subsequent holder of the Note, the "Holder") the sum of [     ]($ ), or
such lesser amount as shall then equal the outstanding  principal amount hereof.
Such amount shall be due and payable on December 8, 2007 (the "Maturity  Date"),
together  with  interest  thereon at a rate per annum equal to the prime rate as
stated by Citibank, N.A. as of the date hereof, (the "Interest Rate"), and which
shall be calculated  on the basis of a 360-day year for actual days elapsed,  on
the terms and  conditions  set forth  hereinafter.  Payment  for all amounts due
hereunder shall be made by certified check or wire transfer to the Holder at c/o
Conversion  Technologies  International,  Inc. Attn: William Amt, President,  or
other such address as the Holder may  designate  by notice to Borrower.  If this
Promissory  Note is  prepaid  in whole  or in part by the  tendering  of  shares
pursuant to Paragraph 2 below, the repayment date shall be the date on which the
Borrower  delivers  a notice to the  Company  in  accordance  with  Paragraph  4
irrevocably  stating the Borrower's  intention to repay the  Promissory  Note by
tendering  such  shares.  The Borrower is  delivering  this  Promissory  Note as
payment of the exercise price for the purchase of the shares of preferred  stock
(the  "Stock")  underlying  the Warrant dated  December 8, 1997 (the  "Warrant")
issued to the Borrower.  The Promissory Note shall be secured by the Stock which
the  Holder  shall  hold in  safe-keeping  as  collateral  for the  indebtedness
represented by this Promissory Note.

         1. Prepayment;  Repayment. The Borrower may at any time prepay in whole
or in part the principal sum, plus accrued interest to date of payment,  of this
Note, without penalty or premium. All sums paid hereon shall be applied first to
accrued,  unpaid interest on this Note and the balance, if any, to the reduction
of the  principal  hereof.  This  Note  shall not be due and  payable  until the
Maturity  Date. On the Maturity Date,  the entire  principal  amount of, and all
accrued interest on, this Note shall  automatically  become  immediately due and
payable without presentment,  demand,  protest or other formalities of any kind,
all of which are hereby expressly waived by the Company.

         2.  Prepayment or Repayment by Tendering of Shares.  Any  prepayment or
repayment  may be made by  instructing  the Company to  withhold  that number of
shares of Stock  currently held by the Company as collateral for this Promissory
Note in accordance  with Paragraph  1(a)(iii) of the Warrant and having a value,
based upon the Current Market Price (as defined in the introductory paragraph of
the Warrant) of the Common Stock,  equal to the  outstanding  principal sum plus
accrued  interest.  The  Company  will  deliver  the  balance  of the shares not
withheld pursuant to the immediately  preceding  sentence of this Paragraph 2 to
the  Borrower at the address set forth in Paragraph 3 below within five (5) days
of the date of such prepayment or repayment, as the case may be.

         3. Events of Default. If any events specified in this Paragraph 3 shall
occur and  continue  uncured for a period of 90 days  following  notice from the
lender such event has occurred(herein  individually  referred to as an "Event of
Default"), the Holder of the Note may, so long as such condition exists, declare
the entire  principal and unpaid accrued  interest  hereon  immediately  due and
payable, by notice in writing to Borrower:

               3.1.  Default in the payment of the principal and unpaid  accrued
interest of the Note when due and payable; or

               3.2. The institution by Borrower of proceedings to be adjudicated
as  bankrupt  or  insolvent,  or the  consent  by  Borrower  to  institution  of
bankruptcy or insolvency  proceedings against Borrower or the filing by Borrower
of a petition or answer or consent seeking  reorganization  or release under the
federal  Bankruptcy  Act, or any other  applicable  federal or state law, or the
consent by Borrower to the filing of any such petition or the  appointment  of a
receiver, liquidator, assignee, trustee or other similar official for all or any
substantial  part of its  property,  of the taking of any action by  Borrower in
furtherance of any such action; or

               3.3.  If,  within  sixty (60) days after the  commencement  of an
action  against  Borrower  (and  service of process in  connection  therewith on
Borrower)  seeking any bankruptcy,  insolvency,  reorganization,  liquidation or
similar  relief under any present or future  statute,  law of  regulation,  such
action  shall not have  been  resolved  in favor of  Borrower  of all  orders or
proceedings thereunder affecting the property of Borrower stayed, or if the stay
of any such order or proceeding  shall  thereafter  be set aside,  or if, within
sixty (60) days after the  appointment  without the consent or  acquiescence  of
Borrower  of any  trustee or  receiver  for all or any  substantial  part of the
property of Borrower, such appointment shall not have been vacated.

hereunder shall be in writing and shall be delivered personally,  sent certified
