                               PROSPECTUS SUMMARY

This summary is qualified in its entirety by the information  included elsewhere
in this  Prospectus  and  the  detailed  information  and  financial  statements
appearing in the documents incorporated in this Prospectus by reference.

The Company

Compositech Ltd. (the "Company" or  "Compositech")  was founded in 1984 by Jonas
Medney and Fred Klimpl, its Chairman and President, respectively, to develop and
market  innovative and superior  copper-clad  fiberglass epoxy laminates used to
make printed circuit boards required by the  electronics  industry.  The Company
was incorporated in the State of New York on June 13, 1984 and was merged into a
newly formed Delaware corporation on January 29, 1988. The primary innovation of
Compositech was to replace the fiberglass cloth component of the laminate with a
more modern and structurally efficient fiberglass core resulting from a uniform,
orthogonally layered construction. The Company has received grants of 22 patents
covering its products,  processes and  apparatus,  including  five in the United
States,  and has submitted ten additional patent  applications.  The Company has
been a development  stage company through 1996. Based on the level of production
and sales anticipated for 1997, the Company has concluded it is no longer in the
development stage as of January 1, 1997.

On July 9, 1996, the Company received net proceeds of approximately $9.9 million
from its initial public offering ("IPO"). Approximately $4.3 million was used to
reduce  debt  substantially  and pay  accrued  interest.  The  Company  used the
remaining  proceeds to add production  modules to its existing equipment and for
working capital.

The Company's innovative laminates are produced using proprietary  processes and
machinery,  designed  by the  Company's  engineering  staff.  The patents on the
laminates,  processes  and  apparatus are  supplemented  with other  proprietary
technology  unprotected  by  patents  and  considered  by the  Company  to be of
substantial value.

Compositech's laminate construction is structurally more efficient, resulting in
enhanced  smoothness and greater  dimensional  stability.  The Company believes,
based on results of  customers'  evaluations,  that its  improved  products  can
economically  replace the fiberglass woven cloth epoxy laminates  currently used
in the electronics industry.  According to the Institute for Interconnecting and
Packaging  Electronic Circuits (the "IPC"), this market exceeded $2.9 billion in
1996.

The Company  successfully  constructed,  debugged  and  operated its first pilot
plant production equipment for laminates with a panel size of 24" x 24" in 1991.
In 1991 and 1992,  Compositech  recruited an initial  sales staff to develop the
market  potential of its product,  continued  refining its product and designing
its production equipment to manufacture laminates with a panel size of 36" x 48"
and initiated a sampling program targeted at major potential customers. In 1994,
the  Company  started  up and began  debugging  its first  production  module to
manufacture  36" x 48" laminates  and, in 1995 and 1996,  produced  laminates on
this equipment in limited quantities for the purpose of making  modifications to
the production processes constituting the module and reformulating the laminates
produced  by the  module.  In the  last  quarter  of  1996,  the  Company  began
installation of advanced production equipment which is now operational.

Industry Overview

Initially, most circuit boards had circuits (traces) on one or two sides. In the
last ten years, rapid  technological  advances in both semiconductor  design and
fabrication  techniques  have placed  significant  demands on the performance of
printed circuit boards. Greater circuit density,  complexity and miniaturization
have increased demand for more sophisticated printed circuit boards. In response
to  this  demand,   multilayer  printed  circuit  boards  were  developed  which
incorporate  multiple layers of metallic traces. The several layers of circuitry
are aligned and bonded together in a stack to form a multilayer  board with both
horizontal  and vertical  electrical  interconnections.  Further  circuit  board
sophistication   is  currently  being  achieved  by  decreasing  the  width  and
separation  of the traces,  drilling  and plating  smaller  holes to connect the
internal  trace layers and precisely  situating the traces and pads on the board
surface to accommodate surface mount components.

These trends in the printed  circuit  board  industry  have placed  increasingly
rigorous demands on the electrical,  thermal, chemical and mechanical properties
of  laminates.  Mechanical  properties  must be  increasingly  more  uniform and
tightly  controlled in order to align the various layers in a multilayer printed
circuit board.  Electrical properties of laminates must be highly consistent and
predictable in order to avoid circuit timing malfunctions.  Thermal stability is
also critical for attaching the  components  and for dense,  high speed systems,
because of the heat generated.

Compositech's  technology is targeted at the fiberglass  laminate segment of the
laminate  industry.  According to the IPC, in 1996 the single- and  double-sided
laminate  market  was  approximately   $1.2  billion  and  the   multilayer/high
performance  laminate  market was  approximately  $1.7  billion,  totaling  $2.9
billion. In these two segments,  the United States' share was approximately $790
million reflecting a growth rate of 20%.

Products

Printed Circuit Board Laminates.  Printed circuit boards are the basic platforms
used  to  interconnect  the  microprocessors,   integrated  circuits  and  other
components essential to the functioning of electronic products.  They consist of
a pattern of electrical  circuitry  resulting from etching copper foil laminated
to a composite made of insulating  materials usually comprised of fiberglass and
epoxy. The laminate itself, therefore, is the copper-clad,  fiberglass and epoxy
core from which printed circuit boards are produced.

Compositech's  Laminates.  CL200+ is the introductory Compositech laminate. This
laminate uses the same basic raw materials as conventional laminates: fiberglass
yarn, epoxy resin and copper foil.  Compositech  combines these materials into a
unique,  more  efficient  laminate.  Conventional  laminates are made from woven
fiberglass  cloth in which  the  yarn is  twisted  and  crimped  in the  weaving
process.  The resultant weave pattern is impressed into the copper foil, thereby
roughening the surface of the laminate.  In the  construction  of  Compositech's
laminates,  the  filaments  of  fiberglass  are not  twisted  but are  wound  in
orthogonal  layers of flat,  continuous  parallel  filaments.  This construction
creates  the  enhanced   smoothness  and  improved   dimensional   stability  of
Compositech's laminates.

High processing  temperature  tolerance is necessary for soldering components to
circuit  boards.  CL200+  uses  a  proprietary  epoxy  resin  formulation  that,
according to Company  tests,  results in a thermal  rating over  200(degree)  C,
which is generally  20(degree) C to  80(degree) C higher than other  copper-clad
fiberglass epoxy laminates. Certain laminates produced from materials other than
fiberglass  epoxy,


                                        6


<PAGE>


addressing a small,  higher cost end of the market,  have thermal  ratings which
equal or exceed those of the Company's introductory CL200+ laminates.

Management  believes that the benefits of Compositech's  laminates should enable
the printed circuit board industry to:

     o    Decrease costs through  reducing waste in the  manufacture of existing
          boards  because  the  improved  dimensional   stability,   temperature
          tolerances and enhanced smoothness increase manufacturers' yields.

     o    Accelerate the development of new products  requiring denser circuitry
          by  permitting  finer lines and smaller  pads. A pad is a portion of a
          conductive pattern which is usually, but not exclusively, used for the
          connection and/or attachment of components.

Compositech's Strategy

The  Company's  objective  is to be  the  leading  manufacturer  of  copper-clad
fiberglass  epoxy  laminates for electronics  equipment.  The Company expects to
achieve this  position  through the effective  exploitation  of its patented and
proprietary products and processes.

Management has targeted the $1.7 billion  multilayer  laminate market sector for
its  initial  sales  efforts to  establish  its  laminates  as the  leading-edge
technology  for  current and future  economical  production  of printed  circuit
boards.

Management  believes that the strategic  value of the Company's  products to its
prospective  customers is to enable them  economically  to produce  increasingly
sophisticated  circuit  boards in a shorter  time  cycle.  This  combination  of
benefits is a basic element of Compositech's product technology thrust.

The Company has patented and developed a flexible  manufacturing process that it
believes can be exceptionally responsive to the ever-changing product iterations
required by the rapid  introduction of new designs into the electronics  market.
The  manufacturing  capacity  can  be  expanded  incrementally  in  response  to
increased market demand.

Management  believes  that  the  Company's   technology  has  global  potential.
According to IPC data,  approximately 70 percent of the world laminate market is
outside of North  America.  The Company  plans to export its  products  and form
strategic alliances to manufacture and market its laminates internationally.

Marketing and Customers

The  Company's  marketing  efforts are  directed to  establishing  good  working
relations with leading-edge  producers of circuit boards.  According to the IPC,
there are over 670 manufacturers of printed circuit boards in North America with
18 companies  comprising over one-third of the market.  The Company has sold its
laminates  principally  on a test  basis  to a select  group of these  companies
considered  to be the key companies for  Compositech's  growth.  During the past
three years,  Compositech has encouraged benchmark  comparisons of its laminates
with current laminates. In virtually all of these evaluations, CL200+ has proven
superior to current laminates.  These results have led several  manufacturers to
begin to use CL200+ for current production  applications,  but such use has been
limited by the  Company's  inability  to supply  laminates  in large


                                        7


<PAGE>


quantities  because  of  working  capital  and  production  constraints.   These
companies  include AMP  Incorporated  ("AMP"),  VIASYSTEMS  Technologies  Corp.,
successor to Lucent  Technologies,  Inc.  (formerly  part of AT&T Corp.),  HADCO
Corporation,  Merix  Corporation and North American Printed Circuits (a division
of TYCO International  Ltd.).  Customers benefit from increased production yield
primarily by reducing waste caused by circuitry misalignment.

Compositech's   laminates   are   designed   and  have  proven  to  be  directly
substitutable for conventional laminates in the circuit board production process
as  demonstrated  by their use in production by  customers.  This  compatibility
enables the circuit board  manufacturer  to substitute  Compositech's  laminates
without the need for additional equipment or new process technology.

The Company  markets to circuit  board  manufacturers  in the United  States and
Canada with its own direct sales force recently  supplemented by two independent
sales  representatives.  The Company's own sales force currently consists of its
President,  its Vice President of Sales and a marketing  assistant.  The Company
plans to use additional  independent sales  representatives  and distributors to
expand sales.

Although  the Company  does not believe that  ultimately  its  business  will be
dependent upon a single  customer,  in view of limited  production  capacity the
Company  currently  is focusing its efforts on a number of select  accounts.  In
1996,  HADCO  Corporation  and  Merix  Corporation  represented  50.8% and 46.4%
respectively,  of the Company's net sales.  The printed  circuit board  industry
generally follows a "just-in-time" strategy by purchasing laminates only as they
are required for production runs.  Accordingly,  the Company  currently does not
have a significant backlog of sales commitments as the orders are matched to the
Company's  present  production  capacity.  The  Company  expects  the backlog to
increase in relation to its planned production expansion.

                               RECENT DEVELOPMENTS

Sale of Convertible Debentures

In May, June and July 1997,  the Company  issued  $3,500,000  of 5%  Convertible
Debentures  (the  "Debentures")  in a private  placement  for which the  Company
received net proceeds of approximately $3,163,000. The Debentures were issued to
provide funds to obtain additional production equipment and for working capital.
Interest  is payable  quarterly.  The  Debentures  are due May 31,  2000 and are
collateralized by the equipment  obtained with the proceeds.  The Debentures are
convertible into shares of Common Stock commencing August 26, 1997 at the lesser
of (i) $6.00 per share or (ii) (a) from August 26, 1997 to  November  24,  1997,
85% and (b) from November 25, 1997 to maturity, 80%, of the closing bid price of
the Common  Stock as  reported  on The  Nasdaq  SmallCap  MarketSM  for the five
trading days prior to the date of  conversion.  The Company may  repurchase  the
Debentures at a 25% premium if the closing bid


                                        8


<PAGE>


price of the Common  Stock is less than $4.00 for any two days out of a five day
trading period.  Trautman Kramer & Company Inc., the placement  agent,  received
warrants to buy 98,000 shares of the  Company's  Common Stock at $6.00 per share
in connection with the sale of Debentures.

Based on a recent SEC  pronouncement,  due to the  difference  between  the fair
market  value of the Common Stock on the date the  Debentures  were sold and the
earliest  discounted   conversion  price,  the  Company  recognized  a  deferred
financing  cost of  $114,000  in the  second  quarter  of 1997  and  expects  to
recognize  $411,000  of such costs in the third  quarter of 1997.  The  deferred
financing  cost is being  amortized over the periods from issuance to August 26,
1997, the date on which the Debentures become convertible.

The Company is negotiating for the sale of additional  convertible debentures of
$4-6 million.


Canadian Joint Venture

On February 6, 1997,  following  an earlier  Memorandum  of  Understanding,  the
Company   agreed  in  principle   with  four  Quebec   institutional   investors
(collectively,  the "Quebec  Investors")  to form a 50/50 joint  venture for the
establishment   of  a  plant  in  the  greater   Montreal  area  to  manufacture
Compositech's laminates. The project cost is estimated to be approximately $24.5
million  with an initial  capitalization  by the  parties of  approximately  $11
million with the balance to be in debt financing for which firm commitments have
been obtained from the National Bank of Canada and  governmental  agencies.  The
Company's $5.5 million  capital  investment in the joint venture is to be funded
by the Quebec Investors purchasing shares of the Company's Common Stock. In July
1997,  the parties  agreed that the  purchase  price of the shares  would be the
weighted  average  closing  price for the 60 day trading  period ending with the
closing of the  agreements  expected to be in early August.  Based on the latest
market values,  there would be an estimated  1,036,000 shares issued. The Quebec
Investors will have an option to sell their 50% interest in the joint venture to
the Company for a like number of shares and,  under certain  circumstances,  the
Company  would have an option to purchase  the  interest  for the same number of
shares.  The  establishment  of the  project  is subject  to the  completion  of
definitive  agreements  and certain other  conditions.  The Company is unable to
predict when, if ever, such conditions will be satisfied.

high degree of risk.  In analyzing the offering,  prospective  investors  should
read this entire Prospectus and the information incorporated herein by reference
and  carefully  consider  the  following  risk  factors in addition to the other
information set forth elsewhere in this Prospectus.

Development Stage Company Until December 31, 1996;  Ability to Continue as Going
Concern; Uncertainty of Future Financial Results

The Company has been a development  stage company through  December 31, 1996 and
has had limited  revenues from the sale of laminates,  has incurred  significant
losses and has had  substantial  negative cash flow since its  inception.  As of
December 31, 1996, the Company had an accumulated  deficit of $20,573,767 and as
of March  31,  1997,  an  accumulated  deficit  of  $21,646,161.  The  Company's
independent  auditors  have  included an  explanatory  paragraph in their report
covering the December 31, 1996 financial statements, which expresses substantial
doubt about the Company's  ability to continue as a going  concern.  The Company
will require,  and is negotiating for,  additional  financing to cover operating
expenses and  expenditures  for additional  production  equipment until revenues
from  operations  are  sufficient  for  these  purposes.   The  Company  expects


                                       10


<PAGE>



significant operating losses to continue in 1997. There can be no assurance that
the Company will successfully  complete  expansion of its production  equipment,
achieve  broad  commercial  acceptance  of its  product or  generate  sufficient
revenues to achieve profitable operations.

Need for Additional Financing

The Company's  available funds,  without giving effect to alternative sources of
revenue,  may not be  sufficient  to raise  the  Company's  production  level to
profitability  or provide  sufficient  working  capital for  expansion of sales.
Consequently,  the Company is in the process of obtaining additional  financing.
The Company recently closed on a private placement of convertible  debentures of
$3,500,000 and is seeking additional financing.  See "Recent Developments." Such
financing may be raised through  additional equity offerings,  joint ventures or
other collaborative relationships,  borrowings or other financings. There can be
no assurance that  additional  financing will be sufficient and available or, if
it is available,  that it will be available on acceptable  terms.  If additional
funds are  raised  through  the  issuance  of equity  securities  or  securities
convertible into equities, the percentage ownership of then current stockholders
of the Company will be reduced and such securities may have rights,  preferences
or privileges  senior to those of the holders of Common Stock. If adequate funds
are  not  available  to  satisfy   either   short-term   or  long-term   capital
requirements, the Company may be required to limit its operations significantly.

Competition

The  laminate  manufacturing  business  is  highly  competitive.  The  Company's
competitors  include major  corporations,  such as General  Electric Company and
AlliedSignal  Inc.,  which have substantial  financial,  marketing and technical
resources.  In 1994, the Company  granted patent immunity on its product patents
to AMP and Akzo  Electronics  Products NV, which,  at the time, were operating a
joint venture which was developing a new process to make linear  laminates.  The
Company  may  need  to  raise  substantial   additional   resources  to  compete
effectively.  There is no  assurance  that the  Company  will be able to compete
successfully in the future.

Management of Growth

The Company intends to expand significantly its overall level of operations. Any
such  expansion,  however,  is  expected  to strain  the  Company's  management,
technical,  financial and other  resources.  To manage growth  effectively,  the
Company  must  add  manufacturing   capacity  and  additional   personnel  while
maintaining a high level of quality and achieving good manufacturing  efficiency
and while  expanding,  training and managing its employee  base.  The  Company's
failure to add  capacity  and manage  growth  effectively  could have a material
adverse  effect on the Company's  business,  financial  condition and results of
operations.

Reliance Upon Key Personnel

The Company  believes that its success will depend to a significant  extent upon
the efforts of its senior  management,  in particular Jonas Medney, its Chairman
and  Chief  Executive  Officer,  and Fred E.  Klimpl,  its  President  and Chief
Marketing Officer, who together invented its technology and founded the Company.
The  Company  maintains  and is the  beneficiary  of $2 million  key person life
insurance  policies  on  each  of  Messrs.   Medney  and  Klimpl.  The  loss  or
unavailability  of either Mr.  Medney or Mr.  Klimpl or other senior  management
could  have a  material  adverse  effect on the  Company's  business,  financial
condition and results of operations.


                                       11


<PAGE>



Dependence on Single Manufacturing Facility

The Company's current laminate  manufacturing  operations are centralized in one
building in Hauppauge, New York, although a joint venture is planned to build an
additional and larger plant in Montreal.  Because the Company currently does not
operate multiple  facilities in different  geographic areas, a disruption of the
Company's   manufacturing    operations   resulting   from   sustained   process
abnormalities,  human error,  government intervention or a natural disaster such
as fire,  earthquake  or flood  could  cause the  Company  to cease or limit its
manufacturing  operations and consequently have a material adverse effect on the
Company's business, financial condition and results of operations.

Uncertainty of Production Quality and Production Costs; Process Disruption

The Company has had  limited  experience  in  producing  laminates  on its first
production-scale  module.  The  Company  recently  added  production  modules to
achieve  higher  quantity  levels and economies of scale.  This expansion is the
first production-scale  expansion undertaken by the Company, and consequently no
assurances can be made that the Company's  production  facilities  will meet the
Company's  production targets in a timely way or that the resultant product will
meet the high  commercial  standard  needed for successful  market  penetration.
Furthermore,  the  expanded  production  facilities  may not be able to  provide
adequate  efficiencies  and  produce  high  yields.  In  addition,  the costs of
production  may not be as low as management  expects,  in which case the Company
may not achieve  profitable  operations.  The Company's business involves highly
complex  manufacturing  processes  which  are  subject  to  disruption.  Process
disruptions  have occurred,  resulting in delays in product  shipments.  Process
disruptions  were  due  to  machine   breakdowns,   lack  of  adequate  interior
atmospheric  control  of  temperature  and  humidity,   electric  utility  power
failures, problems of breaking in an expanded workforce, contamination generated
during  installation  of equipment and  development of processes,  and defective
incoming copper foil.  There can be no assurance that disruptions will not occur
in the  future.  The loss of revenue and  earnings  to the  Company  from such a
disruption could have a materially adverse effect on its results of operations.

Significant Customers

Due to limited productive capacity, the Company has been focusing its efforts on
a few select  accounts.  During 1996,  HADCO  Corporation and Merix  Corporation
accounted for 50.8% and 46.4%,  respectively,  of sales. Loss of these customers
could have a material adverse effect on the Company's business.

Technological Change

The  Company's  laminates  are  used in the  electronic  printed  circuit  board
industry which could encounter  competition  from new technologies in the future
and reduce the number of circuit  boards  required in  electronic  equipment  or
render existing interconnect technology less competitive or obsolete.


                                       12



<PAGE>


Availability of Materials; Dependence Upon Third-Party Supplier

Raw  materials  used by the Company to produce  laminates  are  purchased by the
Company  and in  certain  circumstances  the  Company  bears  the  risk of price
fluctuations.  In  addition,  shortages  of and  defects  in  certain  types  of
materials  have  occurred  in the  past  and may  occur  in the  future.  Future
shortages,  defects or price fluctuations in raw materials could have a material
adverse  effect on the Company's  business,  financial  condition and results of
operations.  Owens Corning a major  fiberglass  manufacturer,  has developed and
continues  to develop  products  to meet the  Company's  processing  and product
requirements.  Should this  manufacturer  not continue  supplying  the Company's
quality and quantity needs,  the Company would have to secure another  supplier.
Such event  could have a material  adverse  effect on the  Company's  ability to
supply  customers  and could  reduce  expected  sales and  increase the costs of
manufacture.  No assurances can be given that an alternative supplier could meet
the Company's quality and quantity needs on satisfactory terms.

Patents and Intellectual Property Protection

The Company  believes  that its patent estate and its know-how are important for
the  protection  of its  technology.  No assurance can be given that any patents
issued to the Company will not be  challenged,  invalidated or  circumvented  or
that such  patents  will  provide  substantial  protection  with  respect to the
Company's  product,  process  or  competitive  position.  In  addition,  certain
proprietary  information  which is considered to be of substantial  value is not
covered by patents and, along with the Company's other intellectual property, is
subject to  misappropriation  or  obsolescence.  In  addition,  the  Company has
granted certain  immunities on its product  patents to potential  competitors of
the Company,  AMP and Akzo Electronics Products NV. The Company also has granted
HT Troplast  AG ("HT"),  a principal  stockholder  of the Company, the exclusive
right to produce and market Compositech's  laminates in Europe, the countries of
the former Soviet Union and Turkey.  HT has exited the laminate  business and no
longer  pursues  an  active  role  therein.  Pursuant  to the  existing  license
agreement  with HT, the Company has the  obligation  to sell only  through HT in
such territories.

Environmental Compliance

The Company uses copper and chemicals in its  manufacturing  process and limited
amounts of solvents for the sole purpose of cleaning its equipment. Although the
Company  believes  that its  facility  complies in all  material  respects  with
existing  environmental  laws and  regulations,  there can be no assurance  that
violations  will  not  occur.   In  the  event  of  any  future   violations  of
environmental law and regulations,  the Company could be held liable for damages
and for the cost of remedial  actions.  In  addition,  environmental  laws could
become  more  stringent  over  time,   imposing  greater  compliance  costs  and
increasing risks and penalties associated with a violation.

Control by Existing Stockholders

As at July 28, 1997, officers,  directors and other significant  stockholders of
the Company owned  approximately  48% of the  Company's  Common Stock and voting
preferred  stock,  including  stock options and warrants  exercisable  within 60
days.  It is  expected  that these  stockholders  will  continue  to control the
management and policies of the Company, including, without limitation, the power
to elect and remove a majority  of  directors  of the  Company  and the power to
approve any action requiring common stockholder approval.  In addition,  some of
these  officers,  directors and other  stockholders,  in connection with certain
outstanding  loans,  have a security  interest  in the


                                       13


<PAGE>


Company's  manufacturing  equipment and all of the Company's  patents and patent
applications or in the Company's U.S. patents and patent applications.

Certain Restrictive Charter and Bylaw Provisions

The  Company's  Certificate  of  Incorporation  and Bylaws  empower the Board of
Directors,  without approval of the  stockholders,  to issue shares of preferred
stock  and  to  fix  the  rights  and  preferences   thereof,  and  to  prohibit
stockholders of the Company from calling a special  meeting unless  requested by
at least a majority of the outstanding  voting shares.  The certificate does not
provide for cumulative voting for election of directors. In addition, the Bylaws
of the Company  provide that while the removal of a director or the entire board
of directors,  with or without cause,  may be accomplished by the holders of the
majority of shares  entitled to vote, any director  designated by HT may only so
be  removed  for cause.  These  provisions  could  have the effect of  deterring
unsolicited  takeovers or other business  combinations or delaying or preventing
changes in control or management of the Company, including transactions in which
stockholders   might  otherwise  receive  a  premium  for  the  securities  over
then-current market prices. In addition,  these provisions may limit the ability
of stockholders to approve  transactions  that they may deem to be in their best
interests.

Possible Depressive Effect of Future Sales of Common Stock; Registration Rights

Immediately  following  this  Offering,  there will be an aggregate of 8,694,964
shares of Common  Stock  outstanding.  In  addition,  an  aggregate of 4,029,100
shares of Common  Stock will be issuable  pursuant to  outstanding  warrants and
options and 307,077  shares will be  issuable  upon the  conversion  of Series A
Convertible  Preferred  Stock.  The  Company has agreed in  principle  with four
Quebec   institutional   investors  to  form  a  50/50  joint  venture  for  the
establishment   of  a  plant  in  the  greater   Montreal  area  to  manufacture
Compositech's  laminates  and which  contemplates  the  issuance of an estimated
1,036,000  shares  of the  Company's  Common  Stock  in  consideration  for  the
investors' capital  investment in the project.  As presently  contemplated,  the
investors  would have an option to sell  their  interest  in the  project to the
Company for an estimated  additional  1,036,000  shares of the Company's  Common
Stock and the Company would have an option to purchase the  investors'  interest
in the project for a like number of shares under certain conditions.  Subject to
restrictions on transfer referred to below, shares of Common Stock issued by the
Company in private  transactions,  are  treated as  "restricted  securities"  as
defined  under the  Securities  Act and in the future may be sold in  compliance
with Rule 144 under the Securities  Act or pursuant to a registration  statement
filed under the Securities Act. As of July 28, 1997, 1,963,615 shares (including
shares which may be acquired upon  conversion of Series A Convertible  Preferred
Stock)  are  eligible  for sale under Rule 144  subject to the  restrictions  on
transfer agreed to between certain  stockholders and the  Representative  of the
Underwriters in the Company's  Initial Public  Offering,  as set forth below. In
addition, 286,500 shares (including shares which may be acquired upon conversion
of Series A Convertible  Preferred Stock and exercise of outstanding  warrants),
are entitled,  subject to certain  restrictions,  to include their shares in any
registration  of  securities  by the  Company  (subject to the  restrictions  on
transfer set forth  below).  Rule 144 generally  provides that a person  holding
restricted  securities  for a period of one year may sell every three  months in
brokerage  transactions  or  market-maker  transactions  an amount  equal to the
greater of (i) one percent (1%) of the Company's  issued and outstanding  Common
Stock or (ii) the average  weekly  trading volume of the Common Stock during the
four calendar  weeks prior to such sale.  Rule 144 also  permits,  under certain
circumstances,  the sale of shares  without any quantity  limitation by a person
who is not an affiliate of the Company and who has satisfied a two-year  holding
period. The


                                       14


<PAGE>


sale of  substantial  numbers of such  shares,  whether  pursuant to Rule 144 or
pursuant to a registration statement, may have a depressive effect on the market
price  of the  Securities.  However,  (i)  the  Company's  directors,  executive
officers and certain principal stockholders,  holding 2,881,235 shares of Common
Stock  (assuming  conversion of Series A Convertible  Preferred  Stock),  in the
aggregate, have agreed not to sell, assign or transfer any of their shares until
July 2, 1998,  (ii) three  holders of an aggregate  of 158,080  shares of Common
Stock have agreed not to sell, assign or transfer any of their shares until July
2, 1998 without the prior  written  consent of the Company,  and (iii) 85 of the
Company's other holders of Common Stock (or Series A Convertible Preferred Stock
convertible  into Common Stock) holding 581,784 shares of Common Stock (assuming
conversion  of Series A  Convertible  Preferred  Stock) have agreed not to sell,
assign or transfer any of their  securities  until January 2, 1998,  without the
prior written consent of the Representative.

Quotation  of  Securities  on The Nasdaq  SmallCap  MarketSM;  Possible  Loss of
Quotation of Securities

The Company's  Common Stock and  Redeemable  Common Stock Warrants are quoted on
The Nasdaq SmallCap MarketSM.  However,  there can be no assurance that a liquid
and active  trading  market  will be  sustained.  In  addition,  there can be no
assurance  that the Company will continue to meet the  maintenance  criteria for
continued  listing of the Common Stock and the  Warrants on The Nasdaq  SmallCap
MarketSM.  The minimum listing  requirements  for The Nasdaq  SmallCap  MarketSM
include,  among other  criteria,  assets of at least $2.0  million,  capital and
surplus of at least $1.0 million, and a minimum bid price per share of $1.00 or,
alternatively,  a market  value of the  public  float of $1.0  million  and $2.0
million in capital and surplus.  In addition,  continued inclusion on The Nasdaq
SmallCap MarketSM requires two market makers.  Furthermore,  The Nasdaq SmallCap
MarketSM  listing and  maintenance  criteria may become more stringent over time
and thus more difficult for the Company to meet. Failure to meet the maintenance
criteria may result in the  discontinuance  of the inclusion of the Common Stock
and the Warrants in The Nasdaq SmallCap  MarketSM.  In such event,  trading,  if
any,  in the Common  Stock and the  Warrants  may  continue to be  conducted  in
non-Nasdaq  over-the-counter markets and investors may find it more difficult to
dispose  of, or to obtain  accurate  quotations  as to the price of,  the Common
Stock and the Warrants.  The Common Stock would then be subject to the risk that
it  could  become   characterized   as  low-priced   or  "penny   stock,"  which
characterization  could severely affect market  liquidity.

Penny Stock Regulation

Broker-dealer  practices in connection  with  transactions in "penny stocks" are
regulated by certain  penny stock rules adopted by the  Securities  and Exchange
Commission.  Penny stocks  generally are equity  securities with a price of less
than $5.00 (other than  securities  registered  on certain  national  securities
exchanges or quoted on the Nasdaq system, provided that current price and volume
information  with respect to  transactions in such securities is provided by the
exchange or system).  The penny stock rules require a broker-dealer,  prior to a
transaction in a penny stock not otherwise  exempt from the rules,  to deliver a
standardized  risk  disclosure  document that provides  information  about penny
stocks and the risks in the penny  stock  market.  The  broker-dealer  also must
provide the customer with current bid and offer  quotations for the penny stock,
the  compensation of the  broker-dealer  and its salesperson in the transaction,
and monthly account statements showing the market value of each penny stock held
in the customer's account. In addition,  the penny stock rules generally require
that prior to a transaction  in a penny stock the  broker-dealer  make a special


                                       15

written  determination  that the penny  stock is a suitable  investment  for the
purchaser  and receive the  purchaser's  written  agreement to the  transaction.
These  disclosure  requirements  may have the  effect of  reducing  the level of
trading activity in the secondary market for a stock that becomes subject to the
penny stock rules.  If the  Securities  become subject to the penny stock rules,
investors in this Offering may find it more difficult to sell their Securities.


                                 USE OF PROCEEDS

The Company will not receive any proceeds  resulting from the sale of the shares
of Common Stock by the Selling Stockholders. See "Selling Stockholders."

The  Warrants  except for the  Warrants  held by Trautman  Kramer & Company Inc.
entitle the holder to purchase  one share of Common Stock from the Company at an
exercise  price of $3.00 per  share.  The  Warrants  held by  Trautman  Kramer &
Company,  Inc.  have an  exercise  price of $3.96 per share.  The  Common  Stock
Purchase Warrants received by Trautman Kramer & Company, Inc. in connection with
the Debentures  have an exercise  price of $6.00 per share.  The exercise of all
the foregoing  warrants  would result in total gross  proceeds to the Company of
$3,324,320.  In the event that any of the Warrants are  exercised in the future,
net cash  proceeds to the  Company  would be used for  general  working  capital
purposes.  Whether, how and to what extent any Warrants will be exercised cannot
be predicted by the Company.

The  shares  of  Common  Stock are being  registered  under the  Securities  Act
pursuant  to the terms of certain  registration  rights  agreements  between the
Selling  Stockholders  and the  Company  entered  into at the time  the  Selling
Stockholders acquired the Warrants and Debentures. Each Selling Stockholder will
be entitled to receive all of the  proceeds  from the future sale of his, her or
its shares of Common  Stock.  Except for the costs of  including  such shares of
Common Stock within the registration  statement of which this Prospectus forms a
part, which costs are borne by the Company,  the Selling  Stockholders will bear
all expenses of any offering by them of their shares of Common Stock,  including
the costs of their counsel and any sales commissions incurred.

                              PLAN OF DISTRIBUTION


The  shares  of  Common  Stock  may be  sold  by  the  Selling  Stockholders  or
Transferees  from  time to time in one or more  transactions  at  market  prices
prevailing at the time of the sale, at prices related to such prevailing  market
prices or at negotiated prices. The Selling Stockholders or Transferees may sell
the shares of Common Stock offered hereby (i) through brokers and dealers;  (ii)
on The Nasdaq SmallCap MarketSM; (iii) any other exchanges upon which the shares
are  listed;  (iv) "at the  market"  to or  through  a  market  maker or into an
existing trading market;  or (v) in other ways not involving  exchanges,  market
makers or established  trading  markets,  including  direct sales to purchasers.
Additionally,   the  shares  may  also  be  publicly   offered  through  agents,
underwriters or dealers.  In such event the Selling  Stockholders or Transferees
may enter into agreements with respect to any such offering.

The  Selling  Stockholders  or  Transferees  and  any  dealers  or  agents  that
participate in the  distribution  of shares of the Common Stock may be deemed to
be  underwriters,  and any  profit on the sale of shares of Common  Stock by the
Selling   Stockholders  or  Transferees   and  any  discounts,   commissions  or
concessions  received  by any such  dealers  or  agents  might be  deemed  to be
underwriting discounts and commissions under the Securities Act.

The  sale  of the  shares  of  Common  Stock  by  the  Selling  Stockholders  or
Transferees may also be effected from time to time by selling shares directly to
purchasers or to or through certain broker-dealers.  In connection with any such
sale, any such  broker-dealer  may act as agent for the Selling  Stockholders or
may purchase from the Selling  Stockholders  or Transferees  all or a portion of
the shares as principal and thereafter may resell any shares so purchased. Sales
by any such broker-dealer, acting as agent or as principal, may be made pursuant
to any of the  methods  described  below.  Such  sales may be made on The Nasdaq
SmallCap MarketSM or other exchanges on which the Company's Common Stock is then
traded, in the over-the-counter  market, in negotiated transactions or otherwise
at prices and at terms then prevailing or at prices related to the  then-current
market prices or at negotiated prices.

The shares of Common Stock  offered under the  Registration  Statement (of which
this  Prospectus  is  part)  may  also be  sold in one or more of the  following
transactions  (i) block  transactions  (which may  involve  crosses)  in which a
broker-dealer may sell all or a portion of such shares as agent but may position
and  resell  all or a  portion  of the  block as  principal  to  facilitate  the
transaction;  (ii)  purchases  by any  such  broker-dealer  for its own  account
pursuant to this Prospectus; (iii) a special

offering,  and exchange  distribution or a secondary  distribution in accordance
with applicable  stock exchange rules; or (iv) ordinary  brokerage  transactions
and transactions in which broker-dealers solicit purchasers. In effecting sales,
broker-dealers  engaged by the Selling  Stockholders  or Transferees may arrange
for other broker-dealers to participate. Broker-dealers will receive commissions
or other compensation from the Selling Stockholders or Transferees in amounts to
be negotiated immediately prior to the sale that will not exceed those customary
in  the  types  of  transactions  involved.   Broker-dealers  may  also  receive
compensation from purchasers of the shares, which is not expected to exceed that
which is customary in the types of transactions involved.

The Selling  Stockholders and Transferees will pay all of the expenses  incident
to the offering and sale of the shares of the Common  Stock  offered  under this
Prospectus, including commissions and fees of dealers or agents. The Company has
paid or will pay all expenses related to the Registration  Statement,  including
registration  fees and the fees of  counsel  or other  experts  retained  by the

with any sale of the shares offered hereby.

Certain  Selling  Stockholders  may from time to time purchase  shares of Common

any or all of the shares of Common Stock offered by them hereby.

Item 15. Indemnification of Directors and Officers.

     Section 145 of the  General  Corporation  Law of the State of Delaware  and
Article   Eighth  of  the  Company's   Amended  and  Restated   Certificate   of
Incorporation  contain provisions for  indemnification  of officers,  directors,
employees  and agents of the Company.  The Amended and Restated  Certificate  of
Incorporation  requires the Company to indemnify such persons to the full extent
permitted by Delaware Law. Each person will be  indemnified in any proceeding if
he acted in good faith and in a manner which he  reasonably  believed to be in ,
or not opposed to, the best interest of the Company. Indemnification would cover
expenses,  including  attorney's  fees,  judgments,  fines and  amounts  paid in
settlement.

     The  Company  has  directors'  and  officers'  liability  insurance.   Such
insurance may cover liabilities asserted against any present or past director or
officer  incurred in the  capacity  of  director or officer  arising out of such
status,  whether  or not the  Company  would  have the power to  indemnify  such
person.

Item 17. Undertakings.

     (a) The undersigned Registrant hereby undertakes:

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

     (i)  to  include  any  prospectus  required  by  Section  10 (a) (3) of the
          Securities Act of 1933;

     (ii) to reflect in the  prospectus  any facts or events  arising  after the
          effective  date of the  Registration  Statement  (or the  most  recent
          post-effective  amendment  thereof)  which,  individually  or  in  the
          aggregate,  represents a  fundamental  change in the  information  set
          forth in the Registration Statement;

     (iii)to  include  any  material  information  with  respect  to the Plan of
          Distribution not previously  disclosed in this Registration  Statement
          or any  material  change  to such  information  in  this  Registration
          Statement;

Provided,   however,  that  paragraphs  (i)  and  (ii)  do  not  apply  to  this
Registration  Statement  if  the  information  required  to  be  included  in  a
post-effective  amendment by those  paragraphs is contained in periodic  reports
filed  by  the  Registrant  pursuant  to  Section  13 or  Section  15 (d) of the
Securities   Exchange  Act  of  1934  and  incorporated  by  reference  in  this
Registration Statement;


                                     II - 2


<PAGE>


          (2) that,  for the  purpose of  determining  any  liability  under the
     Securities Act of 1933, each such post-effective  amendment shall be deemed
     to be a new  registration  statement  relating  to the  securities  offered
     therein,  and the offering of such  securities at that time shall be deemed
     to be the initial bona fide offering thereof;

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

     (b) The undersigned  Registrant  hereby undertakes that, for the purpose of
determining  any liability  under the Securities Act of 1933, each filing of the
Registrant's  annual report  pursuant to Section 13 (a) or section 15 (d) of the
Securities  Exchange  Act of 1934  that is  incorporated  by  reference  in this
registration  statement  shall  be  deemed  to be a new  Registration  Statement
relating to the securities  offered herein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors,  officers and controlling  persons of
the Registrant  pursuant to the provisions  described in the first  paragraph of
Item 15 above, or otherwise, the Registrant has been advised that in the opinion
of the Securities and Exchange commission such indemnification is against public
policy as expressed in said Securities Act and is, therefore,  unenforceable. In
the event that as claim for indemnification against such liabilities (other than
the  payment by the  Registrant  of  expenses  incurred  or paid by a  director,
officer or controlling person of the Registrant in the successful defense of any
action,  suit,  or  proceeding)  is  asserted  by  such  director,   officer  or
controlling  person in connection  with the  securities  being  registered,  the
Registrant  will,  unless in the  opinion  of its  counsel  the  matter has been
settled by controlling precedent,  submit to a court of appropriate jurisdiction
the question  whether such  indemnification  by it is against  public  policy as
expressed in the Securities  Act and will be governed by the final  adjudication
of such issue.

          Re: Shelf Registration of Common Stock of Compositech

Ladies and Gentlemen:

     We refer to the Registration Statement on Form S-3 (the "Registration
Statement") being filed by Compositech Ltd., a Delaware corporation
("Compositech" or the "Company"), with the Securities and Exchange Commission
(the "Commission") under the Securities Act of 1933, as amended (the "Securities
Act"), relating to the shelf registration of the following shares of Compositech
(the "Shares"): (a) 810,476 shares of Common Stock underlying Common Stock
Purchase Warrants, as amended, issued in connection with the Company's private
placement ("Private Placement") which had a final closing on February 15, 1996
(the "Placement Warrants"); (b) 1,555,556 shares of Common Stock issuable upon
conversion of the Company's 5% 1997 Convertible Debentures (the "Debentures");
(c) 76,993 shares of Common Stock underlying Common Stock Purchase Warrants
issued to Trautman Kramer & Company, Inc. as partial compensation in connection
with the Company's Private Placement (the "1996 TK & Co. Warrants") and (d)
98,000 shares of Common Stock underlying Common Stock Purchase Warrants issued
to Trautman Kramer & Company, Inc. as partial compensation in connection with
the Company's private placement of the Debentures (the "1997 TK & Co.
Warrants"). You have requested that we furnish our opinion as to the matters set
forth below.

     In this connection, we have examined originals or copies, certified or
otherwise identified to our satisfaction, of such documents, corporate records,
certificates of public officials and other instruments as we have considered
necessary or advisable for the purpose of this opinion. We have relied as to
factual matters on certificates or other documents furnished by the Company or
its officers and directors and by governmental authorities and upon such other
documents and data as we have deemed appropriate. We have assumed the
authenticity of all documents submitted to us as originals and the conformity to
original documents of all documents submitted to us as copies. We have not
independently verified such information and assumptions. We express no opinion
as to the

law of any jurisdiction other than the laws of the State of New York and the
General Corporation Law of the State of Delaware.

     Subject to the foregoing, we are of the opinion that the Shares have been
duly authorized and, upon delivery and payment therefor in accordance with the
terms of the Placement Warrants, Debentures, 1996 TK & Co. Warrants and 1997 TK
& Co. Warrants, respectively, will be validly issued, fully paid and
nonassessable.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to our firm which appears in the
Prospectus constituting a part thereof under the caption "Legal Opinions." In
giving such consent, we do not thereby admit that we come within the category of
persons whose consent is required under Section 7 of the Securities Act or the
rules and regulations of the Commission thereunder.


                                        Very truly yours,


                                        /s/ Donovan Leisure Newton & Irvine

of the  Debentures,  will be  convertible  into shares of the  Company's  common

     NOW THEREFORE,  in  consideration  of the premises and the mutual covenants
contained  herein,  the parties  hereto,  intending to be legally bound,  hereby
agree as follows:

1.   PURCHASE AND SALE OF DEBENTURES

evidencing the Debentures,  to the Escrow Agent or its designated depository. By
executing  and  delivering  this  Agreement,  Buyer and the Company  each hereby
agrees to observe the terms and conditions of the Joint Escrow Instructions, all

                             ______________________

                             For the Account of:

                             ______________________

2.   BUYER'S  REPRESENTATIONS,  WARRANTIES;  ACCESS TO INFORMATION;  INDEPENDENT
     INVESTIGATION.

     Buyer  represents and warrants to and covenants and agrees with the Company
as follows:

          a. Buyer is purchasing the Debentures  (and the shares of Common Stock
     issuable  upon  conversion  thereof)  for its own account,  for  investment
     purposes only and not with a view towards or in connection  with the public
     sale or distribution thereof in violation of the Securities Act.

          b. Buyer is (i) an  "accredited  investor"  within the meaning of Rule
     501 of Regulation D under the  Securities  Act, (ii)  experienced in making
     investments of the kind contemplated by this Agreement,  (iii) capable,  by
     reason of its business and financial experience, of evaluating the relative
     merits  and  risks of an  investment  in the  Securities,  and (iv) able to
     afford the loss of its investment in the Securities.

          c.  Buyer  understands  that  the  Debentures  (and the  Common  Stock
     issuable upon conversion thereof) are being offered and sold by the Company
     in reliance  on an  exemption  from the  registration  requirements  of the
     Securities  Act and  equivalent  state  securities and "blue sky" laws, and
     that the Company is relying upon the  accuracy  of, and Buyer's  compliance
     with, Buyer's  representations,  warranties and covenants set forth in this
     Agreement  to  determine  the   availability  of  such  exemption  and  the
     eligibility of Buyer to purchase the Debentures;

          d. Buyer has been furnished  with or provided  access to all materials
     relating to the business,  financial  position and results of operations of
     the  Company,  and all other  materials  requested by Buyer to enable it to
     make an informed investment decision with respect to the Debentures.


                                      -2-
<PAGE>


          e. Buyer  acknowledges  that it has been  furnished with copies of the
     Company's  Annual Report on Form 10-KSB for the fiscal year ended  December
     31,  1996 and all  other  reports  and  documents  heretofore  filed by the
     Company with the  Securities  and Exchange  Commission  (the  "Commission")
     pursuant to the Securities Act and the Securities  Exchange Act of 1934, as
     amended (the  "Exchange  Act") since  December 31, 1996  (collectively  the
     "Commission Filings").

          f. Buyer  acknowledges  that in making its  decision to  purchase  the
     Debentures it has (i) relied upon independent investigations made by it and
     its professional  advisors,  (ii) visited the Company's principal executive
     offices and been given access and the  opportunity  to examine all material
     agreements,  books and records of the Company and all documents relating to
     the Company's private placement of the Debentures,  and (iii) been given an
     opportunity  to ask questions of and to receive  answers from the Company's
     executive officers, directors and management personnel concerning the terms
     and conditions of the private placement of the Debentures by the Company.

          g. Buyer  understands  that the  Securities  have not been approved or
     disapproved by the Commission or any state  securities  commission and that
     the foregoing authorities have not reviewed any documents or instruments in
     connection  with the  offer and sale to it of the  Securities  and have not
     confirmed or determined  the adequacy or accuracy of any such  documents or
     instruments.

          h. This Agreement has been duly and validly  authorized,  executed and
     delivered  by  Buyer  and  is  a  valid  and  binding  agreement  of  Buyer
     enforceable against it in accordance with its terms,  subject to applicable
     bankruptcy, insolvency, fraudulent conveyance,  reorganization,  moratorium
     and similar laws affecting creditors' rights and remedies generally.

          i. Neither  Buyer nor its  affiliates  nor any person acting on its or
     their behalf has the  intention of entering,  or will enter into,  prior to
     the closing,  any put option, short position or other similar instrument or
     position  with respect to the Common Stock and neither Buyer nor any of its
     affiliates  nor any person  acting on its or their  behalf  will use at any
     time shares of Common  Stock  acquired  pursuant to this  Agreement  or the
     Debentures  to settle  any put  option,  short  position  or other  similar
     instrument  or  position  that  may have  been  entered  into  prior to the
     execution of this Agreement.

          (ii) Except as disclosed in the Commission  Filings,  the Company does
     not own or  control,  directly  or  indirectly,  any  interest in any other

     business  organization,  association,  trust or other business entity.  The
     Company has no subsidiaries.

          b. Organization; Reporting Company Status.

          (i) The Company is a corporation duly organized,  validly existing and
     in good  standing  under  the  laws of the  State of  Delaware  and is duly

     failure to so qualify would have a material adverse effect on the business,
     properties,  prospects,  condition  (financial  or otherwise) or results of
     operations of the Company or on the consummation of any of the transactions
     contemplated by this Agreement (a "Material Adverse Effect").

          (ii) The Company has  registered  the Common Stock pursuant to Section
     12 of the Exchange Act and has timely filed with the Commission all reports
     and  information  required  to be filed  by it  pursuant  to all  reporting

     Dealers,  Inc. Automated Quotation ("NASDAQ") Small  Capitalization  Market
     System and the Company has not  received any notice  regarding,  and to its
     knowledge there is no threat,  of the termination or  discontinuance of the

          c. Authorized  Shares. The Company has duly and validly authorized and
     reserved for issuance  shares of Common Stock  sufficient in number for the

     Rights Agreement") and the Joint Escrow  Instructions and to perform all of
     its obligations hereunder and thereunder (including the issuance,  sale and

     Agreement and the Registration  Rights  Agreement,  and the consummation by
     the Company of the transactions  contemplated hereby and thereby,  has been
     duly  authorized  by all  necessary  corporate  action  on the  part of the
     Company.  Each of this Agreement and the Registration  Rights Agreement has
     been duly and validly executed and delivered by the Company and constitutes
     a valid and  binding  agreement  of the Company  enforceable  against it in
     accordance with its terms,  subject to applicable  bankruptcy,  insolvency,
     fraudulent   conveyance,   reorganization,   moratorium  and  similar  laws
     affecting  creditors'  rights and remedies  generally.  The Debentures have
     been duly and validly  authorized  for  issuance by the Company  and,  when
     executed  and  delivered  by  the  Company,   will  be  valid  and  binding
     obligations of the Company  enforceable against it in accordance with their
     terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance,
     reorganization, moratorium and similar laws affecting creditors' rights and
     remedies generally.

          f.  Non-contravention.  The  execution  and delivery by the Company of
     this Agreement and the Registration  Rights Agreement,  the issuance of the
     Debentures (and the Common Stock issuable upon conversion thereof), and the
     consummation by the Company of the other transactions  contemplated  hereby
     and thereby, do not and will not conflict with or result in a breach by the
     Company of any of the terms or  provisions  of, or constitute a default (or
     an event which,  with  notice,  lapse of time or both,  would  constitute a
     default) under, the articles of incorporation or by-laws of the Company, or
     any  indenture,  mortgage,  deed of trust or other  material  agreement  or
     instrument  to which the Company is a party or by which its  properties  or
     assets are bound, or any law, rule, regulation,  decree,  judgment or order
     of any court or public or governmental  authority having  jurisdiction over
     the  Company or any of its  properties  or assets,  except  such  conflict,
     breach or default which would not have a Material Adverse Effect.

          g. Approvals.  No  authorization,  approval or consent of any court or
     public or governmental  authority is required to be obtained by the Company
     for the issuance and sale of the Debentures  (and the Common Stock issuable
     upon conversion thereof) to Buyer as contemplated by this Agreement, except
     such authorizations,  approvals and consents that have been obtained by the
     Company prior to the date hereof.

          h. Commission Filings. None of the Commission Filings contained at the
     time they were filed any untrue  statement of a material fact or omitted to
     state any material fact required to be stated  therein or necessary to make
     the statements made therein, in light of the circumstances under which they
     were made, not misleading.

          i.  Absence  of  Certain  Changes.  Since the  Balance  Sheet Date (as
     defined in Section  3.m.),  there has not  occurred  any  change,  event or
     development in the business,  financial condition,  prospects or results of
     operations of the Company,  and there has not existed any condition  having
     or reasonably likely to have, a Material Adverse Effect.

          j. Full Disclosure.  There is no fact known to the Company (other than
     general economic or industry conditions known to the public generally) that
     has not been fully  disclosed  in writing to the Buyer that (i)  reasonably
     could be  expected  to have a Material  Adverse  Effect or (ii)  reasonably
     could be expected to  materially  and  adversely  affect the 



                                      -5-
<PAGE>


     ability  of the  Company  to  perform  its  obligations  pursuant  to  this
     Agreement or the Registration Rights Agreement.

          k. Absence of Litigation. There is no action, suit, claim, proceeding,
     inquiry  or   investigation   pending  or,  to  the  Company's   knowledge,
     threatened,  by or before  any court or  public or  governmental  authority
     which, if determined  adversely to the Company or any of its  subsidiaries,
     would have a Material Adverse Effect.

          l. Absence of Events of Default.  No "Event of Default" (as defined in
     any agreement or instrument to which the Company or any of its subsidiaries
     is a party) and no event which,  with notice,  lapse of time or both, would
     constitute  an  Event of  Default  (as so  defined),  has  occurred  and is
     continuing, which could have a Material Adverse Effect.

          m.  Financial  Statements;  No  Undisclosed  Liabilities.  Seller  has
     delivered to Buyer true and complete copies of its audited balance sheet as
     at December 31, 1996 and the related  audited  statements of operations and

     adjustments  and the  absence  of  footnotes)  and in  conformity  with the
     practices  consistently  applied by the Company without modification of the
     accounting  principles used in the preparation thereof, and fairly presents
     the financial position, results of operations and cash flows of the Company
     as at the dates and for the periods  indicated.  For purposes  hereof,  the

     would have been required to be reflected in, reserved  against or otherwise
     described in the Balance Sheet or in the notes  thereto in accordance  with
     GAAP,  which was not fully  reflected  in,  reserved  against or  otherwise
     described in the Balance  Sheet or the notes thereto or was not incurred in
     the  ordinary  course  of  business  consistent  with  the  Company's  past
     practices since the Balance Sheet Date.

          n.  Compliance with Laws;  Permits.  The Company is in compliance with
     all laws, rules, regulations,  codes, ordinances and statutes (collectively
     "Laws") applicable to it or to the conduct of its business, except for such
     non-compliance  which would not have a Material Adverse Effect. The Company
     possesses all permits, approvals,  authorizations,  licenses,  certificates
     and  consents  from all  public  and  governmental  authorities  which  are
     necessary  to conduct its  business,  except for those the absence of which
     would not have a Material Adverse Effect.

          o. Related Party  Transactions.  Except as set forth in the Commission
     Filings,  neither  the  Company  nor  any of  its  officers,  directors  or
     "Affiliates" (as such term is

<PAGE>


     defined in Rule 12b-2 under the Exchange  Act) has borrowed any moneys from

     indirect  interest  constituting more than a one percent equity (or similar
     profit participation)  interest in, or controls or is a director,  officer,
     partner,  member or employee of, or  consultant to or lender to or borrower
     from,  or has the right to  participate  in the  profits  of, any person or
     entity which is (x) a competitor,  supplier,  customer,  landlord,  tenant,
     creditor or debtor of the Company or any of its  subsidiaries,  (y) engaged

     other arrangement with the Company.

          p. Insurance.  The Company  maintains  property and casualty,  general
     liability, workers' compensation, environmental hazard, personal injury and
     other  similar  types of insurance  with  financially  sound and  reputable
     insurers  that is adequate,  consistent  with  industry  standards  and the
     Company's historical claims experience. The Company has not received notice
     from,  and has no knowledge of any threat by, any insurer  (that has issued
     any  insurance  policy to the Company)  that such  insurer  intends to deny
     coverage  under or cancel,  discontinue  or not renew any insurance  policy
     presently in force.

          q. Securities Law Matters.  Based,  in part, upon the  representations
     and  warranties of Buyer set forth in Section 2 hereof,  the offer and sale

     securities   convertible  into  or  exchangeable  or  exercisable  for  the
     Debentures  or  Common  Stock  or any such  other  securities)  within  the
     six-month period next preceding the date hereof, except as disclosed in the

     take, any action (including,  without  limitation,  any offering or sale to
     any person or entity of the Debentures or shares of Common Stock), so as to
     make  unavailable  the exemption  from  Securities Act  registration  being
     relied  upon by the  Company  for  the  offer  and  sale  to  Buyer  of the
     Debentures  (and the Common  Stock  issuable  upon  conversion  thereof) as
     contemplated  by  this  Agreement.  No  form  of  general  solicitation  or
     advertising  has  been  used or  authorized  by the  Company  or any of its
     officers,  directors or Affiliates in connection  with the offer or sale of

          Law, or may have any liability under any Environmental Law;

               (v) the Company does not have any current contingent liability in

     required  to file under  applicable  Laws,  except for such Tax  Returns in
     respect  of which  the  failure  to so file  does not and  could not have a
     Material  Adverse  Effect;  all such Tax Returns are true and  accurate and
     have been prepared in compliance with all applicable  Laws; the Company has
     paid all Taxes due and owing by it (whether or not such Taxes are  required
     to be  shown  on a Tax  Return)  and have  withheld  and  paid  over to the
     appropriate  taxing  authorities all Taxes which it is required to withhold
     from amounts paid or owing to any employee, stockholder,  creditor or other
     third parties; and since the Balance Sheet Date, the charges,  accruals and
     reserves for Taxes with respect to the Company  (including  any  provisions
     for  deferred  income  taxes)  reflected  on the books of the  Company  are
     adequate  to cover any Tax  liabilities  of the  Company if its current tax
     year were treated as ending on the date hereof.

          (ii) No claim has been made by a taxing  authority  in a  jurisdiction
     where the Company does not file tax returns that such corporation is or may
     be subject to taxation by that jurisdiction. There are no foreign, federal,
     state or local tax audits or administrative or 


                                      -10-
<PAGE>


     judicial proceedings pending or being conducted with respect to the Company
     other than a New York State tax audit presently being conducted, the result
     of which will not have a Material Adverse Effect; no information related to
     Tax matters has been  requested  by any  foreign,  federal,  state or local
     taxing  authority;  and,  except as  disclosed  above,  no  written  notice
     indicating  an intent to open an audit or other review has been received by
     the Company from any  foreign,  federal,  state or local taxing  authority.
     There  are no  material  unresolved  questions  or  claims  concerning  the
     Company's Tax liability. The Company (A) has not executed or entered into a
     closing agreement  pursuant to ss. 7121 of the Internal Revenue Code or any
     predecessor  provision thereof or any similar provision of state,  local or
     foreign  law;  or  (B)  has  not  agreed  to or is  required  to  make  any
     adjustments  pursuant to ss. 481 (a) of the  Internal  Revenue  Code or any
     similar  provision of state,  local or foreign law by reason of a change in
     accounting  method  initiated by the Company or any of its  subsidiaries or
     has any knowledge  that the IRS has proposed any such  adjustment or change
     in  accounting  method,  or has any  application  pending  with any  taxing
     authority requesting  permission for any changes in accounting methods that
     relate to the business or  operations  of the Company.  The Company has not
     been a United States real property holding  corporation  within the meaning
     of ss. 897(c)(2) of the Internal Revenue Code during the applicable  period
     specified in ss. 897(c)(1)(A)(ii) of the Internal Revenue Code.

          (iii) The  Company has not made an  election  under ss.  341(f) of the
     Internal  Revenue Code.  The Company is not liable for the Taxes of another
     person that is not a subsidiary  of the Company  under (A) Treas.  Reg. ss.
     1.1502-6 (or comparable  provisions of state, local or foreign law), (B) as
     a transferee or successor,  (C) by contract or indemnity or (D)  otherwise.
     The  Company is not a party to any tax sharing  agreement.  The Company has
     not made any  payments,  is obligated to make  payments or is a party to an
     agreement  that could  obligate it to make any  payments  that would not be
     deductible under ss. 280G of the Internal Revenue Code.

     For purposes of this Section 3.u.:

          "IRS" means the United States Internal Revenue Service.

          "Tax" or "Taxes" means federal,  state,  county,  local,  foreign,  or
     other income, gross receipts, ad valorem, franchise, profits, sales or use,
     transfer,  registration,  excise, utility,  environmental,  communications,
     real or personal property,  capital stock, license,  payroll, wage or other
     withholding,  employment,  social security,  severance,  stamp, occupation,
     alternative  or  add-on  minimum,  estimated  and  other  taxes of any kind
     whatsoever  (including,   without  limitation,   deficiencies,   penalties,
     additions to tax, and interest  attributable  thereto)  whether disputed or
     not.

          "Tax  Return"  means any  return,  information  report or filing  with
     respect to Taxes,  including any schedules  attached  thereto and including
     any amendment thereof.

          v. Property.  The Company does not own any real property.  The Company
     has good and  marketable  title to all personal  property owned by it, free
     and  clear  of all  liens,  encumbrances  and  defects  except  such as are
     described in the Commission Filings or



                                      -11-
<PAGE>


     such as do not  materially  affect  the value of such  property  and do not
     materially  interfere  with the use made  and  proposed  to be made of such
     property by the Company;  and any real  property and  buildings  held under
     lease by the Company are held by it under valid, subsisting and enforceable
     leases with such  exceptions as are not material and do not interfere  with
     the use made and proposed to be made of such  property and buildings by the
     Company.

          w. Intellectual  Property.  The Company owns or possesses adequate and
     enforceable  rights to use all patents,  patent  applications,  trademarks,
     trademark applications,  trade names, service marks, copyrights,  copyright
     applications,   licenses,  know-how  (including  trade  secrets  and  other
     unpatented  and/or  unpatentable  proprietary or confidential  information,
     systems or procedures) and other similar rights and  proprietary  knowledge
     (collectively,  "Intangibles") necessary for the conduct of its business as
     now being conducted and as described in the Commission Filings. To the best
     of the  Company's  knowledge,  the  Company  is not  infringing  upon or in
     conflict   with  any  right  of  any  other  person  with  respect  to  any
     Intangibles.  Except as disclosed in the Commission Filings, no claims have
     been asserted by any person to the ownership or use of any  Intangibles and
     the Company has no knowledge of any basis for such claim.

          x. [Reserved]

          y. Internal Controls and Procedures.  The Company  maintains  accurate
     books and records and internal accounting controls which provide reasonable
     assurance that (i) all  transactions  to which the Company is a party or by
     which   its   properties   are  bound  are   executed   with   management's
     authorization;  (ii) the reported accountability of the Company's assets is
     compared with  existing  assets at regular  intervals;  (iii) access to the
     Company's  assets  is  permitted  only  in  accordance  with   management's
     authorization; and (iv) all transactions to which the Company is a party or
     by which its  properties  are bound are  recorded  as  necessary  to permit
     preparation of the financial  statements of the Company in accordance  with
     U.S. generally accepted accounting principles.

          z.  Payments  and  Contributions.  Neither  the Company nor any of its
     directors,  officers or, to its knowledge, other employees has (i) used any
     Company   funds  for  any   unlawful   contribution,   endorsement,   gift,
     entertainment  or other unlawful  expense  relating to political  activity;
     (ii) made any direct or indirect  unlawful  payment of Company funds to any
     foreign or domestic government  official or employee;  (iii) violated or is
     in violation of any provision of the Foreign Corrupt Practices Act of 1977,
     as amended;  or (iv) made any bribe,  rebate,  payoff,  influence  payment,
     kickback or other  similar  payment to any person  with  respect to Company
     matters.

          aa.  Customers.  To  the  Company's  knowledge,  except  as  otherwise
     provided to Buyer in writing by the Company, neither  _________________ nor
     ________________  plan or intend to discontinue or decrease their purchases

     customers  is strong and all  accounts  receivable  of such  customers  are
     current.

                                      -12-

          bb. No Misrepresentation. No representation or warranty of the Company
     contained in this Agreement,  any schedule,  annex or exhibit hereto or any
     agreement,  instrument  or  certificate  furnished  by the Company to Buyer
     pursuant to this  Agreement,  contains  any untrue  statement of a material
     fact or omits to state a material  fact  required  to be stated  therein or
     necessary to make the statements therein, not misleading.

     4.   CERTAIN COVENANTS AND ACKNOWLEDGMENTS.

     a. Restrictive  Legend.  Buyer  acknowledges and agrees that, upon issuance
pursuant  to this  Agreement,  the  Debentures  (and any shares of Common  Stock
issued  in  conversion   thereof)  shall  have  endorsed  thereon  a  legend  in
substantially  the  following  form  (and a  stop-transfer  order  may be placed
against  transfer of the Debentures and the shares of Common Stock issuable upon
conversion thereon):

     "THESE  SECURITIES  HAVE NOT BEEN  REGISTERED  UNDER THE  SECURITIES ACT OF
     1933, AS AMENDED (THE  "SECURITIES  ACT"),  OR THE  SECURITIES  LAWS OF ANY
     STATE,  AND ARE BEING  OFFERED AND SOLD  PURSUANT TO AN EXEMPTION  FROM THE
     REGISTRATION  REQUIREMENTS  OF THE  SECURITIES  ACT AND  SUCH  LAWS.  THESE
     SECURITIES MAY NOT BE SOLD OR TRANSFERRED  EXCEPT  PURSUANT TO AN EFFECTIVE
     REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE
     EXEMPTION FROM THE REGISTRATION  REQUIREMENTS OF THE SECURITIES ACT OR SUCH
     OTHER LAWS."

     b. Filings. The Company shall make all necessary filings in connection with
the sale of the Debentures to the Buyer as required by all applicable  Laws, and
shall provide a copy thereof to the Buyer promptly after such filing.

     c.  Reporting  Status.  So long as the Buyer  beneficially  owns any of the
Securities,  the Company shall file all reports  required to be filed by it with
the Commission pursuant to Section 13 or 15(d) of the Exchange Act.

     d. Use of Proceeds. The Company shall use the proceeds from the sale of the
Debentures  (excluding  amounts  paid by the Company for legal fees and finder's
fees in  connection  with such sale) solely for working  capital and to fund the
purchase of property,  plant and equipment at its principal executive offices in
Hauppauge, New York.

     e.  Equipment.  Within six months after the Closing Date, the Company shall
have purchased the equipment set forth on Schedule I and such equipment shall be
operational  and fully  functional  as provided on Schedule I. It is  understood
that the  maximum  conversion  price of $6.00  provided  in  Section  3.1 of the
Debenture has been agreed to in reliance of the accuracy of the  information set
forth on Schedule I as of the date of this Agreement.  It is further  understood
that any  projection  provided to the Buyer by the Company



                                      -13-
<PAGE>


were  prepared  in good faith based upon the  Company's  most  current  internal
information and that, as  projections,  they will be subject to changes based on
actual results.

     f. Listing.  Except to the extent the Company becomes  eligible to list its
Common Stock on The New York Stock Exchange or obtained authorization to include
the Common Stock for quotation on the NASDAQ National Market System, the Company
shall use its best  efforts to maintain  its listing of the Common  Stock on the
NASDAQ Small Capitalization Market System.

     g. Reserved  Conversion Shares. The Company at all times from and after the
date hereof  shall have a  sufficient  number of shares of Common Stock duly and
validly authorized and reserved for issuance to satisfy the conversion, in full,
of the  Debentures  (assuming  for purposes of this  Section  3.g., a conversion
price of $1.50).

     5.   TRANSFER AGENT INSTRUCTIONS.

     a. The Company  undertakes  and agrees that no  instruction  other than the
instructions  referred  to  in  this  Section  5  and  customary  stop  transfer
instructions  prior to the registration and sale of the Common Stock pursuant to
an effective Securities Act registration statement will be given to its transfer
agent for the Common Stock and that the Common Stock issuable upon conversion of
the Debentures  otherwise shall be freely  transferable on the books and records
of the Company as and to the extent provided in this Agreement, the Registration
Rights  Agreement and  applicable  law.  Nothing  contained in this Section 5.a.
shall  affect in any way Buyer's  obligations  and  agreement to comply with all
applicable  securities  laws upon resale of such Common Stock.  If, at any time,
Buyer provides the Company with an opinion of counsel reasonably satisfactory to
the Company that registration of the resale by Buyer of such Common Stock is not
required under the Securities Act and that the removal of restrictive legends is
permitted  under  applicable  law, the Company shall permit the transfer of such
Common Stock and, promptly instruct the Company's transfer agent to issue one or
more  certificates  for Common Stock without any  restrictive  legends  endorsed
thereon.

     b. The Company  shall  permit  Buyer to  exercise  its right to convert the
Debentures by telecopying an executed and completed  Notice of Conversion to the
Company and  delivering to the Company by express  courier  within five business
days  thereafter,  the original  Notice of Conversion and the  Debentures  being
converted.  Each  date on which a Notice  of  Conversion  is  telecopied  to and
received by the Company in accordance with the provisions hereof shall be deemed
a Conversion  Date. The Company shall transmit the  certificates  evidencing the
shares of Common Stock issuable upon conversion of any Debentures (together with
certificates  evidencing  any principal  amount of the  Debentures  not being so
converted) to Buyer via express  courier,  by electronic  transfer or otherwise,
within five business days after receipt by the Company of the original Notice of
Conversion and the Debentures to be converted (the "Delivery Date").

     c. The Company  understands  that a delay in the  issuance of the shares of
Common  Stock upon such  conversion  beyond the  Delivery  Date could  result in
economic  loss to Buyer.  As  compensation  to Buyer for such loss (and not as a
penalty),  the Company  agrees 



                                      -14-
<PAGE>

to pay to Buyer for late issuance of Common Stock upon  conversion in accordance
with the following  schedule (where "No. Business Days" is defined as the number
of business days beyond five (5) days from Delivery Date):

                                                Compensation For Each
                                                  $10,000 Principal

                  1                                      $25
                  2                                      $50
                  3                                      $75
                  4                                     $100

                  7                                     $175

                  10                                    $250
            more than 10                                $250 + $100 for each
                                                       Business Day Late beyond
                                                       10 days

     The  Company  shall pay to Buyer the  compensation  described  above by the
transfer of  immediately  available  funds upon Buyer's  demand.  Nothing herein
shall limit Buyer's right to pursue actual damages for the Company's  failure to
issue and deliver  Common Stock to Buyer,  and in addition to any other remedies
which may be available to Buyer,  in the event the Company  fails for any reason
to effect  delivery of such shares of Common  Stock  within five  business  days
after the  relevant  Delivery  Date,  Buyer  shall be  entitled  to rescind  the
relevant  Notice of  Conversion  by  delivering  a notice to such  effect to the
Company  whereupon  the  Company  and  Buyer  shall  each be  restored  to their
respective  original  positions  immediately prior to delivery of such Notice of
Conversion.

     For purposes of this Section  5.c., an act of God shall excuse the delay in
issuance of shares of Common Stock upon  conversion  beyond the Delivery Date in
the event that acts of war or terrorism,  or some other  catastrophic  event not
encountered  in  business   renders  the  Company's  or  its  transfer   agent's
performance  impossible.  Such delay in issuance of shares shall be excused only
for so long as the act of God in fact renders  performance  impossible but in no
event longer than seven (7) business days.

     6.   DELIVERY INSTRUCTIONS.

     The  Debentures  shall be  delivered  by the  Company to the  Escrow  Agent
pursuant  to Section  1(b) hereof on a  "delivery-against-payment  basis" at the
Closing.

contrary  contained herein,  the Escrow Agent shall not be authorized to release

     d. Third  Party  Claims.  Promptly  after  receipt by either  party  hereto
seeking indemnification  pursuant to this Section 11 (an "Indemnified Party") of
written  notice  of any  investigation,  claim,  proceeding  or other  action in
respect  of which  indemnification  is  being  sought  (each,  a  "Claim"),  the
Indemnified  Party promptly shall notify the party against whom  indemnification
pursuant to this  Section 11 is being sought (the  "Indemnifying  Party") of the
commencement thereof; but the omission to so notify the Indemnifying Party shall
not relieve it from any liability that it otherwise may have to the  Indemnified
Party, except to the extent that the Indemnifying Party is materially prejudiced
and  forfeits  substantive  rights and  defenses by reason of such  failure.  In
connection  with any  Claim as to which  both  the  Indemnifying  Party  and the
Indemnified  Party are  parties,  the  Indemnifying  Party  shall be entitled to
assume the defense thereof. Notwithstanding the assumption of the defense of any
Claim by the Indemnifying  Party, the Indemnified  Party shall have the right to
employ  separate  legal counsel and to participate in the defense of such Claim,
and the Indemnifying Party shall bear the reasonable fees,  out-of-pocket  costs
and expenses of such  separate  legal counsel to the  Indemnified  Party if (and
only if):  (x) the  Indemnifying  Party  shall  have  agreed  to pay such  fees,
out-of-pocket costs and expenses, (y) the Indemnified Party and the Indemnifying
Party  reasonably  shall have concluded that  representation  of the Indemnified
Party  by the  Indemnifying  Party  by  the  same  legal  counsel  would  not be
appropriate  due to actual or, as reasonably  determined by legal counsel to the
Indemnified Party,  potentially  differing interests between such parties in the
conduct  of the  defense  of such  Claim,  or if  there  may be  legal  defenses
available to the  Indemnified  Party that are in addition to or  disparate  from
those available to the Indemnifying  Party, or (z) the Indemnifying  Party shall
have failed to employ legal counsel  reasonably  satisfactory to the Indemnified
Party within a reasonable  period of time after  notice of the  commencement  of
such  Claim.  If  the  Indemnified  Party  employs  separate  legal  counsel  in
circumstances  other than as described  in clauses  (x),  (y) or (z) above,  the
fees, costs and expenses of such legal counsel shall be borne exclusively by the
Indemnified  Party.  Except as provided above, the Indemnifying Party shall not,
in connection  with any Claim in the same  jurisdiction,  be liable for the fees
and expenses of more than one firm of legal  counsel for the  Indemnified  Party
(together with appropriate local counsel). The Indemnifying



                                      -19-
<PAGE>

Party shall not,  without the prior  written  consent of the  Indemnified  Party
(which  consent shall not  unreasonably  be withheld),  settle or compromise any
Claim or  consent  to the  entry  of any  judgment  that  does  not  include  an
unconditional release of the Indemnified Party from all liabilities with respect
to such Claim or judgment.

     e. Other Claims.

     In the event one party  hereunder  should have a claim for  indemnification
that does not involve a claim or demand  being  asserted by a third  party,  the
Indemnified   Party   promptly  shall  deliver  notice  of  such  claim  to  the
Indemnifying  Party. If the Indemnified  Party disputes the claim,  such dispute
shall  be  resolved  by  mutual  agreement  of the  Indemnified  Party  and  the
Indemnifying  Party or by binding  arbitration  conducted in accordance with the
procedures and rules of the American Arbitration Association.  Judgment upon any
award rendered by any arbitrators  may be entered in any court having  competent
jurisdiction thereof.

     12.  GOVERNING LAW: MISCELLANEOUS.

     This Agreement  shall be governed by and interpreted in accordance with the
laws of the State of New York, without regard to the conflicts of law principles
of such state.  Each of the parties  consents to the jurisdiction of the federal
courts whose  districts  encompass any part of the City of New York or the state
courts of the State of New York  sitting  in the City of New York in  connection
with any dispute arising under this Agreement and hereby waives,  to the maximum
extent  permitted by law, any objection,  including any objection based on forum
non conveniens, to the bringing of any such proceeding in such jurisdictions.  A
facsimile  transmission  of this signed  Agreement shall be legal and binding on
all parties  hereto.  This Agreement may be signed in one or more  counterparts,
each of which shall be deemed an original.  The headings of this  Agreement  are

interpretation  of, this Agreement.  If any provision of this Agreement shall be
invalid   or   unenforceable   in   any   jurisdiction,   such   invalidity   or
unenforceability  shall  not  affect  the  validity  or  enforceability  of  the
remainder of this Agreement or the validity or  enforceability of this Agreement
in any other  jurisdiction.  This Agreement may be amended only by an instrument
in writing  signed by the party to be charged with  enforcement.  This Agreement
supersedes all prior agreements and understandings among the parties hereto with
respect to the subject matter hereof.

payment of or on  account of the  principal  amount of this  Debenture,  for the
conversion of this Debenture and for all other  purposes,  and the Company shall
not be  affected  by any  notice to the  contrary.  All such  payments  and such
conversion  shall be valid and  effectual to satisfy and discharge the liability
upon this  Debenture to the extent of the sum or sums so paid or the  conversion
so made.


                                    Article 3
                             CONVERSION OF DEBENTURE

     SECTION 3.1 Conversion; Conversion Price. At the option of the Holder, this
Debenture may be converted, either in whole or in part, up to the full principal
amount  hereof (in  increments of not less than $10,000  principal  amount) into
Common Shares (calculated as to each such conversion to the nearest 1/100th of a
share),  at any  time,  and from  time to time,  (i) from and after the 90th day
following  May 28,  1997  until  the  180th  day  following  May  28,  1997 at a
Conversion  Price  equal to 85% of the Market  Price and (ii) from and after the
181st  day  following  May 28,  1997  until  this  Debenture  is paid in full at
maturity,  at a  Conversion  Price equal to 80% of the Market  Price,  but in no
event  shall  the  Conversion  Price be in excess  of $6.00  per  Common  Share;
provided,  however,  that the  Holder  shall not have the right to  convert  any
portion of this  Debenture  to the  extent  that the  issuance  to the Holder of
Common Shares upon such  conversion  would result in the Holder being deemed the
"beneficial  owner" of 5% or more of the then  outstanding  Common Shares within
the meaning of Rule 13d-3 of the Securities Exchange Act of 1934, as amended. At
the  Company's  option,  the amount of accrued  and  unpaid  interest  as of the
Conversion  Date shall not be subject to  conversion  but


                                       -5-


<PAGE>


instead may be paid in cash as of the Conversion  Date; if the Company elects to
convert the amount of accrued and unpaid interest at the Conversation  Date into
Common  Stock,  the Common  Stock  issued to the  Holder  shall be valued at the
Conversion Price.

     Notwithstanding  anything to the contrary  contained herein, if a Valuation
Event occurs during any Valuation  Period, a new Valuation Period shall begin on
the Trading Day immediately following the occurrence of such Valuation Event and
end on the  Conversion  Date;  provided that if a Valuation  Event occurs on the
fifth  day of any  Valuation  Period,  then the  Conversion  Price  shall be the
Current  Market Price of the Common Shares on such day; and  provided,  further,
that the Holder may,  in its  discretion,  postpone  such  Conversion  Date to a
Trading Day which is no more than five Trading Days after the  occurrence of the
latest  Valuation Event. In the event that the Holder deems the Valuation Period
to be other than the five Trading Days immediately prior to the Conversion Date,
the Holder shall give written  notice of such fact to the Company at the time of
conversion.

For purposes of this  Section  3.1, a  "Valuation  Event" shall mean an event in
which  the  Company  at any time  during a  Valuation  Period  takes  any of the
following actions:

     (a) subdivides or combines its Capital Shares;

     (b) pays a dividend in its Capital  Shares or makes any other  distribution
of its Capital Shares;

     (c) issues any additional Capital Shares (the "Additional Capital Shares"),
otherwise than as provided in the foregoing Sections 3.1(a) and 3.1(b) above, at
a price per share  less,  or for other  consideration  lower,  than the  Current
Market  Price  in  effect  immediately  prior  to  such  issuances,  or  without
consideration, except for issuances under employee benefit plans consistent with
those presently in effect and issuances under  presently  outstanding  warrants,
options or convertible securities;

     (d)  issues  any  warrants,  options or other  rights to  subscribe  for or
purchase  any  Additional  Capital  Shares  and the  price  per  share for which
Additional  Capital  Shares may at any time  thereafter be issuable  pursuant to
such  warrants,  options or other rights  shall be less than the Current  Market
Price in effect immediately prior to such issuance;

     (e) issues any securities  convertible  into or exchangeable or exercisable
for Capital Shares and the consideration per share for which Additional  Capital
Shares may at any time  thereafter  be  issuable  pursuant  to the terms of such
convertible,  exchangeable  or  exercisable  securities  shall be less  than the
Current Market Price in effect immediately prior to such issuance;

     (f) makes a distribution  of its assets or evidences of indebtedness to the
holders of its Capital  Shares as a dividend in  liquidation or by way of return
of  capital  or other  than as a dividend  payable  out of  earnings  or surplus
legally  available  for the payment of  dividends  under  applicable  law or any
distribution to such holders made in respect of the sale of


                                       -6-


<PAGE>


all  or  substantially  all  of the  Company's  assets  (other  than  under  the
circumstances  provided for in the foregoing  Sections  3.1(a) through  3.1(e)),
provided, in each case, that such distribution  described in this Section 3.1(f)
does not constitute an Event of Default; or

     (g) takes any action  affecting the number of Outstanding  Capital  Shares,
other than an action  described in any of the foregoing  Sections 3.1(a) through
3.1(f)  hereof,  inclusive,  which  in the  opinion  of the  Company's  Board of
Directors,  determined in good faith,  would have a material adverse effect upon
the rights of the Holder at the time of a conversion of this Debenture.

     SECTION 3.2  Exercise  of  Conversion  Privilege.  (a)  Conversion  of this
Debenture may be exercised, in whole or in part, by the Holder by telecopying an
executed and completed  notice of conversion in the form annexed hereto as Annex
I (the  "Conversion  Notice")  to the  Company  and  sending a  manually  signed
original  Conversion Notice and this Debenture to the Company by express courier
not later  than five (5)  Business  Days  next  following  the date on which the
telecopied  Conversion  Notice has been  transmitted  to the Company;  provided,
however, if for two or more Trading Days in any five Trading Day period (whether
or not  consecutive),  the Market Price per Common Share is less than $4.00,  at
least 24 hours prior to the  delivery of a  Conversion  Notice the Holder  shall
notify the Company  that it may deliver a Conversion  Notice  within 10 Business
Days from the date of the Company's receipt of such  notification.  Each date on
which a  Conversion  Notice is  telecopied  to and  received  by the  Company in
accordance with the provisions of this Section 3.2 shall constitute a Conversion
Date.  The Company shall convert the Debenture and issue the Common Stock Issued
at Conversion  effective as of the Conversion  Date. The Conversion  Notice also
shall state the name or names (with  addresses) of the persons who are to become
the holders of the Common Stock Issued at  Conversion  in  connection  with such
conversion.  Upon surrender for conversion,  this Debenture shall be accompanied
by a proper  assignment  hereof to the  Company  or be  endorsed  in  blank.  As
promptly  as  practicable  after the  receipt of the  Conversion  Notice and the
surrender of this  Debenture as  aforesaid,  but in any event not more than five
Business  Days  after  the  Company's  receipt  of such  Conversion  Notice  and
surrender of this Debenture, the Company shall (i) issue the Common Stock issued
at  Conversion  in  accordance  with the  provisions of this Article 3, and (ii)
cause to be mailed  for  delivery  by  overnight  courier  to the  Holder  (X) a
certificate or certificate(s)  representing the number of Common Shares to which
the Holder is entitled by virtue of such  conversion,  (Y) cash,  as provided in
Section 3.4, in respect of any fraction of a Share issuable upon such conversion
and (Z) cash in the amount of accrued and unpaid  interest as of the  Conversion
Date to the extent payable in cash. Such conversion shall be deemed to have been
effected at the time at which the  Conversion  Notice  indicates so long as this
Debenture  shall have been  surrendered  as aforesaid at such time,  and at such
time the rights of the Holder of this  Debenture,  as such,  shall cease and the
Person and Persons in whose name or names the Common Stock Issued at  Conversion
shall be issuable shall be deemed to have become the holder or holders of record
of the Common Shares represented thereby. The Conversion Notice shall constitute
a contract  between  the Holder and the  Company,  whereby  the Holder  shall be
deemed to subscribe for the number of Common Shares which it will be entitled to
receive  upon  such  conversion  and,  in  payment  and   satisfaction  of  such
subscription (and for any cash adjustment to which it is


                                       -7-


<PAGE>


entitled  pursuant to Section 3.4), to surrender  this  Debenture and to release
the Company from all liability  thereon.  No cash payment  aggregating less than
$1.50 shall be required to be given unless specifically requested by the Holder.

     (b) If,  at any time  after  the date of this  Debenture,  (i) the  Company
challenges,  disputes  or denies  the right of the  Holder  hereof to effect the
conversion  of this  Debenture  into Common  Shares or  otherwise  dishonors  or
rejects any Conversion  Notice  delivered in accordance with this Section 3.2 or
(ii) any third  party who is not and has never been an  Affiliate  of the Holder
commences any lawsuit or  proceeding  or otherwise  asserts any claim before any
court or  public or  governmental  authority  which  seeks to  challenge,  deny,
enjoin, limit, modify, delay or dispute the right of the Holder hereof to effect
the conversion of this Debenture into Common Shares,  then the Holder shall have
the right, by written notice to the Company,  to require the Company to promptly
redeem  this  Debenture  for  cash at a  redemption  price  equal to 125% of the
principal  amount hereof together with all accrued and unpaid  interest  thereon
(the "Mandatory  Purchase  Amount").  Under any of the  circumstances  set forth
above,  the  Company  shall be  responsible  for the  payment  of all  costs and
expenses of the Holder,  including  reasonable  legal fees and expenses,  as and
when incurred in disputing any such action or pursuing its rights  hereunder (in
addition to any other rights of the Holder).

     SECTION 3.3 [This Section Reserved]

     SECTION  3.4  Fractional  Shares.  No  fractional  Common  Shares  or scrip
representing  fractional  Common Shares shall be issued upon  conversion of this
Debenture.  Instead of any  fractional  Common Shares which  otherwise  would be
issuable  upon  conversion  of this  Debenture,  the  Company  shall  pay a cash
adjustment in respect of such fraction in an amount equal to the same  fraction.
No cash  payment  of less  than  $1.50  shall be  required  to be  given  unless
specifically requested by the Holder.

     SECTION 3.5  Reclassification,  Consolidation,  Merger or  Mandatory  Share
Exchange. At any time while this Debenture remains outstanding and any principal
amount hereof has not been converted,  in case of any reclassification or change
of Outstanding  Common Shares issuable upon conversion of this Debenture  (other
than a change in par value, or from par value to no par value per share, or from
no par  value  per  share  to par  value  or as a  result  of a  subdivision  or
combination  of  outstanding   securities   issuable  upon  conversion  of  this
Debenture) or in case of any  consolidation,  merger or mandatory share exchange
of the  Company  with  or into  another  corporation  (other  than a  merger  or
mandatory  share  exchange  with another  corporation  in which the Company is a
continuing  corporation  and which  does not result in any  reclassification  or
change,  other than a change in par value, or from par value to no par value per
share,  or from no par  value  per  share  to par  value,  or as a  result  of a
subdivision or combination of Outstanding  Common Shares upon conversion of this
Debenture), or in the case of any sale or transfer to another corporation of the
property  of the Company as an entirety or  substantially  as an  entirety,  the
Company, or such successor, resulting or purchasing corporation, as the case may
be, shall, without payment of any additional  consideration therefor,  execute a
new Debenture providing that the Holder shall have the right to convert such new
Debenture (upon terms and conditions not less favorable to


                                       -8-


<PAGE>


the Holder than those in effect  pursuant to this Debenture) and to receive upon
such exercise, in lieu of each Common Share theretofore issuable upon conversion
of this  Debenture,  the kind and amount of shares of stock,  other  securities,
money or property receivable upon such reclassification,  change, consolidation,
merger,  mandatory share exchange,  sale or transfer by the holder of one Common
Share  issuable  upon  conversion  of this  Debenture  had this  Debenture  been
converted  immediately prior to such  reclassification,  change,  consolidation,
merger,  mandatory  share  exchange or sale or transfer.  The provisions of this
Section 3.5 shall  similarly  apply to  successive  reclassifications,  changes,
consolidations, mergers, mandatory share exchanges and sales and transfers.

     SECTION 3.6 Adjustments to Conversion  Ratio. For so long as this Debenture
is  outstanding,  if the Company (i) issues and sells  pursuant to an  exemption
from registration under the Securities Act (A) Common Shares at a purchase price
representing  a percentage  of the Current  Market Price on the date of issuance
thereof that is lower than 75%,  (B) warrants or options with an exercise  price
representing a percentage of the Current Market Price on the date of issuance of
the  warrants  or  options  that is lower  than 75%,  except  for  stock  option
agreements or stock incentive  agreements,  or (C) convertible,  exchangeable or
exercisable securities with a right to exchange at lower than 75% of the Current
Market  Price on the Common  Shares on the date of  issuance or  conversion,  as
applicable, of such convertible,  exchangeable or exercisable securities, except
for stock option agreements or stock incentive  agreements;  and (ii) grants the
right to the purchaser(s)  thereof to demand that the Company register under the
Securities  Act such Common  Shares  issued or the Common  Shares for which such
warrants  or options  may be  exercised  or such  convertible,  exchangeable  or
exercisable  securities  may be  converted,  exercised  or  exchanged,  then the
Conversion  Ratio  shall  be  reduced  to equal  the  lowest  of any such  lower
percentages.

     SECTION 3.7 Optional Redemption Under Certain Circumstances. If, for two or
more Trading Days in any five-Trading  Day period (whether or not  consecutive),
the Market  Price per Common Share is less than $4.00,  then the  Company,  upon
notice  delivered  to the Holder as  provided  in Section  3.8,  may redeem this
Debenture (but only with respect to such principal amount as to which the Holder
has not  theretofore  furnished a Conversion  Notice in compliance  with Section
3.2), at 125% of the  principal  amount  thereof,  together with all accrued and
unpaid interest thereon to the date of redemption (the "Redemption  Date") which
shall be no later  than  thirty  (30)  days  following  the  expiration  of such
five-Trading  Day period.  Except as set forth in this  Section 3.7, the Company
shall not have the right to prepay or redeem this Debenture.

     SECTION 3.8 Notice of Redemption. Notice of optional redemption pursuant to
Section  3.7 shall be  provided  by the  Company to the  Holder in  writing  (by
registered mail or overnight  courier at the Holder's last address  appearing in
the Company's security registry) not less than seven nor more than 15 days prior
to the Redemption Date, which notice shall specify the Redemption Date and refer
to Section 3.7  (including a statement of the Market Price per Common Share) and
this Section 3.8.

     SECTION 3.9 Surrender of Debentures.  Upon any redemption of this Debenture


                                      -9-


<PAGE>


pursuant to Section 3.7, the Holder shall either  deliver this Debenture by hand
to the Company at its principal  executive  offices or surrender the same to the
Company at such  address by express  courier.  Payment of the  redemption  price
specified  in Section  3.7 shall be made by the  Company  to the Holder  against
receipt of this  Debenture (as provided in this Section 3.9) by wire transfer of
immediately  available  funds to such  account(s) as the Holder shall specify to
the  Company.  If  payment of such  redemption  price is not made in full by the
Redemption Date, the Holder shall again have the right to convert this Debenture
as provided in Article 3 hereof.

such  rescission;  provided,  however,  in the  case  of any  Event  of  Default
described  in  paragraphs  (c),  (d) or (f) above,  the entire then  outstanding

     2. Registration.

     (a) Filing and Effectiveness of Registration  Statement.  The Company shall
prepare  and file  with the  Commission  not  later  than the 60th day after the
Closing  Date, a  Registration  Statement  relating to the offer and sale of the
Registrable   Securities   (provided   however  that  if  the  Company  files  a

Statement  effective under the Securities Act as promptly as practicable but not
later  than 120 days  after  the  Closing  Date (as  defined  in the  Securities
Purchase  Agreement),  assuming for purposes hereof a Conversion Price under the
Debentures of $2.25 per share.

     (b)  Underwritten  Offering.  If the  offering  pursuant to a  Registration
Statement contemplated by Section 2(a) hereof involves an underwritten offering,
the  Investors who hold a  majority-in-interest  of the  Registrable  Securities

counsel to represent their interests,  and an investment banker (or bankers) and
manager (or managers) to administer the offering,  which  investment  banker (or
bankers)  or manager  (or  managers)  shall be  reasonably  satisfactory  to the
Company.  The  Investors who hold the  Registrable  Securities to be included in
such underwriting  shall pay all underwriting  discounts and commissions of such
investment  banker (or  bankers)  and  manager  (or  managers)  so  selected  in
accordance with this Section 2(b) with respect to their Registrable Securities.

     (c)  Registration  Default.  If the  Registration  Statement  covering  the
Registrable  Securities  required to be filed by the Company pursuant to Section
2(a)  hereof  is not (i)  filed  with the  Commission  by the 60th day after the
Closing Date (or if earlier,  by the Filing Date) or (ii) declared  effective by
the  Commission  within 150 days after the  Closing  Date  (either of which,  an
"Initial  Date"),  then the  Company  shall  make the  payments  to the  Initial
Investor as provided in the next sentence.  The amount to be paid by the Company
to the Initial  Investor  shall be determined as of each  Computation  Date, and
such  amount  shall be equal to 3% of the  Purchase  Price  (as  defined  in the
Securities  Purchase  Agreement) from the Initial Date to the first  Computation
Date and for each Computation Date thereafter, calculated on a pro rata basis to
the date on which the  Registration  Statement is filed with (in the event of an
Initial Date pursuant to (c)(i) above) or declared effective by (in the event of
an Initial  Date  pursuant  to  (c)(ii)  above) the  Commission  (the  "Periodic
Amount").  The full Periodic  Amount shall be paid by the Company to the Initial
Investor by wire transfer of immediately available funds within three days after
each Computation Date.

days after the Initial Date and, if the  Registration  Statement  required to be
filed by the Company  pursuant to Section 2(a) has not theretofore been declared
effective  by the  Commission,  each date  which is 30 days  after the  previous
Computation Date until such Registration Statement is so declared effective.

     (d)  Eligibility  for Use of Form S-3. The Company agrees that at such time
as it meets all the  requirements  for the use of  Securities  Act  Registration
Statement on Form S-3 it shall file all reports and  information  required to be
filed  by it with the  Commission  in a timely  manner  and take all such  other
action so as to maintain such eligibility for the use of such form.

     (e) In the event the Current Market Price under the Debentures  declines to
$3.00,  the Company shall file an  additional  Registration  Statement  with the
Commission  for such  additional  number of  Registrable  Securities as would be
issuable upon  conversion  of the  Debentures,  in addition to those  previously
registered,  assuming a Conversion  Price of $1.00 per share.  The Company shall
prepare and file with the Commission not later than the 30th day  thereafter,  a
Registration  Statement  relating  to the  offer  and  sale of such  Registrable
Securities  and shall use its best  efforts to cause the  Commission  to declare
such  Registration  Statement  effective under the Securities Act as promptly as
practicable but not later than 60 days thereafter.

     3.  Obligations of the Company.  In connection with the registration of the
Registrable Securities, the Company shall:

     (a)  Promptly  (i) prepare  and file with the  Commission  such  amendments
(including   post-effective   amendments)  to  the  Registration  Statement  and
supplements  to the  Prospectus  as may be  necessary  to keep the  Registration
Statement  continuously  effective and in compliance  with the provisions of the
Securities  Act applicable  thereto so as to permit the Prospectus  forming part
thereof to be current and useable by  Investors  for resales of the  Registrable
Securities  for a period  of two years  from the date on which the  Registration
Statement is first declared  effective by the Commission (the "Effective  Time")
or such shorter period that will terminate when all the  Registrable  Securities
covered  by the  Registration  Statement  have been  sold  pursuant  thereto  in
accordance with the plan of distribution provided in the Prospectus, transferred
pursuant to Rule 144 under the  Securities  Act or  otherwise  transferred  in a
manner that  results in the delivery of new  securities  not subject to transfer
restrictions under the Securities Act (the "Registration  Period") and (ii) take
all  lawful  action  such that each of (A) the  Registration  Statement  and any
amendment  thereto  does  not,  when it  becomes  effective,  contain  an untrue
statement  of a material  fact or omit to state a material  fact  required to be
stated therein or necessary to make the statements  therein,  not misleading and
(B) the Prospectus forming part of the Registration Statement, and any amendment
or  supplement  thereto,  does not at any time  during the  Registration  Period
include an untrue  statement of a material fact or omit to state a material fact
required to be stated  therein or necessary to make the statements  therein,  in
light  of  the  circumstances  under  which  they  were  made,  not  misleading.
Notwithstanding the foregoing  provisions of this Section 3(a), the Company may,
during the Registration  Period,  suspend the use of the Prospectus for a period


                                      -4-


<PAGE>


not to exceed 60 days (whether or not consecutive) in any 12-month period if the
Board of Directors of the Company determines in good faith that because of valid
business  reasons,  including  pending  mergers  or other  business  combination
transactions, the planned acquisition or divestiture of assets, pending material
corporate  developments  and similar events,  it is in the best interests of the
Company to suspend such use, and prior to or  contemporaneously  with suspending
such  use the  Company  provides  the  Investors  with  written  notice  of such
suspension, which notice need not specify the nature of the event giving rise to
such  suspension.  At the end of any such suspension  period,  the Company shall
provide the Investors with written notice of the termination of such suspension.

     (b) During the  Registration  Period,  comply  with the  provisions  of the
Securities Act with respect to the disposition of all Registrable  Securities of
the Company covered by the Registration Statement until such time as all of such
Registrable  Securities  have been disposed of in  accordance  with the intended
methods of disposition  by the Investors as set forth in the Prospectus  forming
part of the Registration Statement;

     (c) (i)  Prior  to the  filing  with  the  Commission  of any  Registration
Statement (including any amendments thereto) and the distribution or delivery of

Investors  (and their  counsel)  reasonably may propose and (ii) furnish to each
Investor whose Registrable Securities are included in the Registration Statement
and its legal counsel identified to the Company,  (A) promptly after the same is
prepared and publicly distributed, filed with the Commission, or received by the

amendment or supplement thereto, and (B) such number of copies of the Prospectus
and all amendments and  supplements  thereto and such other  documents,  as such
Investor may reasonably  request in order to facilitate  the  disposition of the
Registrable Securities owned by such Investor;

     (d) (i)  Register  or qualify  the  Registrable  Securities  covered by the
Registration  Statement  under  such  securities  or  "blue  sky"  laws  of such
jurisdictions  as  the  Investors  who  hold  a   majority-in-interest   of  the
Registrable  Securities being offered reasonably request,  (ii) prepare and file
in such jurisdictions such amendments (including post-effective  amendments) and
supplements  to such  registrations  and  qualifications  as may be necessary to
maintain the effectiveness  thereof at all times during the Registration Period,
(iii) take all such other lawful  actions as may be  necessary to maintain  such
registrations and  qualifications in effect at all times during the Registration
Period,  and (iv) take all such other  lawful  actions  reasonably  necessary or
advisable to qualify the Registrable  Securities for sale in such jurisdictions;
provided,  however,  that  the  Company  shall  not be  required  in  connection
therewith  or as a  condition  thereto  to (A)  qualify  to do  business  in any
jurisdiction  where it would not  otherwise  be required to qualify but for this
Section 3(d), (B) subject itself to general taxation in any such jurisdiction or
(C) file a general consent to service of process in any such jurisdiction;

each  Investor  of the  occurrence  of any  event,  as a  result  of  which  the
Prospectus included in


                                      -5-


<PAGE>


the Registration Statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements  therein,  in light of the circumstances  under
which they were made, not misleading,  and promptly  prepare an amendment to the
Registration  Statement and  supplement to the Prospectus to correct such untrue
statement or  omission,  and deliver a number of copies of such  supplement  and
amendment to each Investor as such Investor may reasonably request;

     (f) As promptly as practicable  after becoming aware of such event,  notify
each Investor who holds  Registrable  Securities being sold (or, in the event of
an  underwritten  offering,  the managing  underwriters)  of the issuance by the
Commission  of any stop order or other  suspension of the  effectiveness  of the
Registration  Statement at the earliest possible time and take all lawful action
to effect  the  withdrawal,  recession  or  removal  of such stop order or other
suspension;

     (g) (i) Cause all the Registrable  Securities  covered by the  Registration
Statement  to be listed  on the  principal  national  securities  exchange,  and
included in an inter-dealer quotation system of a registered national securities
association, on or in which securities of the same class or series issued by the
Company are then listed or included;

     (h) Maintain a transfer agent and registrar,  which may be a single entity,
for  the  Registrable  Securities  not  later  than  the  effective  date of the
Registration Statement;

     (i)  Cooperate  with the Investors who hold  Registrable  Securities  being
offered to facilitate the timely  preparation and delivery of  certificates  for
the Registrable  Securities to be offered pursuant to the Registration Statement
and  enable  such  certificates  for the  Registrable  Securities  to be in such
denominations  or amounts,  as the case may be, as the Investors  reasonably may
request and registered in such names as the Investors may request;  and,  within
three business days after a Registration  Statement  which includes  Registrable
Securities  is declared  effective  by the  Commission,  deliver and cause legal
counsel  selected  by the  Company  to  deliver  to the  transfer  agent for the
Registrable   Securities  (with  copies  to  the  Investors  whose   Registrable
Securities  are  included  in  such   Registration   Statement)  an  appropriate
instruction and opinion of such counsel;

     (j) Take all such other lawful actions reasonably necessary to expedite and
facilitate the disposition by the Investors of their  Registrable  Securities in
accordance with the intended methods  therefor  provided in the Prospectus which
are customary under the circumstances.

     (k) Make generally available to its securityholders as soon as practicable,
but in any event  not later  than 18  months  after (i) the  effective  date (as
defined in Rule 158(c) under the Securities Act) of the Registration  Statement,
and (ii) the effective date of each post-effective amendment to the Registration
Statement,  as the case may be, an  earnings  statement  of the  Company and its
subsidiaries  complying  with Section 11(a) of the  Securities Act and the rules
and regulations of the Commission  thereunder  (including,  at the option of the
Company, Rule 158);


                                      -6-

     (l)  In  the  event  of  an  underwritten  offering,  promptly  include  or
incorporate  in a  Prospectus  supplement  or  post-effective  amendment  to the
Registration  Statement such information as the managers reasonably agree should
be included therein and to which the Company does not reasonably object and make
all required filings of such Prospectus  supplement or post-effective  amendment
as soon as  practicable  after it is  notified  of the matters to be included or
incorporated in such Prospectus supplement or post-effective amendment;

     (m)  Enter  into  such  customary  agreements  (including  an  underwriting
agreement in customary form in the event of an  underwritten  offering) and take
such  other  lawful  and  reasonable  action  to  expedite  and  facilitate  the
registration  and disposition of the Registrable  Securities,  and in connection
therewith,  if an  underwriting  agreement  is entered  into,  cause the same to
contain  indemnification  provisions and procedures  substantially  identical to
those set forth in this Agreement;

     (n)  (i)  Make  reasonably  available  for  inspection  by  Investors,  any
underwriter  participating  in any  disposition  pursuant  to  the  Registration
Statement,  and  any  attorney,  accountant  or  other  agent  retained  by such
Investors or any such  underwriter  all relevant  financial  and other  records,
pertinent   corporate   documents   and   properties  of  the  Company  and  its
subsidiaries,  and (ii) cause the Company's officers, directors and employees to
supply  all  information  reasonably  requested  by such  Investors  or any such
underwriter,  attorney,  accountant or agent in connection with the Registration
Statement, in each case, as is customary for similar due diligence examinations;
provided,  however,  that  all  records,  information  and  documents  that  are
designated  in  writing  by  the  Company,   in  good  faith,  as  confidential,
proprietary  or containing  any material  non-public  information  shall be kept
confidential by such Investors and any such underwriter, attorney, accountant or
agent (pursuant to an appropriate  confidentiality  agreement in the case of any
such  holder or agent),  unless  such  disclosure  is made  pursuant to judicial
process in a court  proceeding  (after first  giving the Company an  opportunity
promptly  to seek a  protective  order  or  otherwise  limit  the  scope  of the
information  sought to be  disclosed)  or is required  by law, or such  records,
information or documents  become  available to the public generally or through a
third party not in violation of an accompanying  obligation of  confidentiality;
and provided further that, if the foregoing inspection and information gathering
would otherwise disrupt the Company's  conduct of its business,  such inspection
and information  gathering shall, to the maximum extent possible, be coordinated
on behalf of the Investors and the other parties entitled thereto by one firm of
counsel designed by and on behalf of the Investors and other parties;

     (o) In connection with any underwritten offering, make such representations
and warranties to the Investors  participating in such underwritten offering and
to the managers,  in form,  substance and scope as are  customarily  made by the
Company to underwriters in secondary underwritten offerings;

     (p) In  connection  with any  underwritten  offering,  obtain  opinions  of
counsel  to the  Company  (which  counsel  and  opinions  (in  form,  scope  and
substance)  shall be reasonably  satisfactory to the managers)  addressed to the
underwriters,  covering  such  matters as are  customarily  covered in  opinions
requested in secondary  underwritten offerings (it being


                                      -7-


<PAGE>


agreed that the matters to be covered by such opinions  shall  include,  without
limitation,  as of the date of the opinion and as of the  Effective  Time of the
Registration  Statement or most recent post-effective  amendment thereto, as the
case may be, the absence from the  Registration  Statement  and the  Prospectus,
including  any  documents  incorporated  by  reference  therein,  of  an  untrue
statement of a material  fact or the omission of a material  fact required to be
stated therein or necessary to make the  statements  therein (in the case of the
Prospectus,  in light of the  circumstances  under  which  they  were  made) not
misleading, subject to customary limitations);

     (q) In connection  with any  underwritten  offering,  obtain "cold comfort"
letters and updates  thereof  from the  independent  public  accountants  of the
Company (and, if  necessary,  from the  independent  public  accountants  of any
subsidiary  of the Company or of any business  acquired by the Company,  in each
case for which  financial  statements and financial data are, or are required to
be,  included in the  Registration  Statement),  addressed  to each  underwriter
participating  in such  underwritten  offering (if such underwriter has provided
such letter,  representations  or documentation,  if any, required for such cold
comfort  letter to be so addressed),  in customary form and covering  matters of
the type  customarily  covered  in "cold  comfort"  letters in  connection  with
secondary underwritten offerings;

     (r) In connection with any  underwritten  offering,  deliver such documents
and certificates as may be reasonably required by the managers, if any.

     (s) In the event that any  broker-dealer  registered under the Exchange Act
shall  be an  "Affiliate"  (as  defined  in Rule  2729(b)(1)  of the  rules  and
regulations of the National  Association of Securities Dealers,  Inc. (the "NASD
Rules") (or any successor  provision thereto)) of the Company or has a "conflict
of interest" (as defined in Rule  2720(b)(7) of the NASD Rules (or any successor
provision  thereto)) and such broker-dealer  shall underwrite,  participate as a
member  of  an  underwriting  syndicate  or  selling  group  or  assist  in  the
distribution  of  any  Registrable   Securities   covered  by  the  Registration
Statement,  whether  as a  holder  of  such  Registrable  Securities  or  as  an
underwriter,  a  placement  or sales  agent or a broker  or  dealer  in  respect
thereof, or otherwise,  the Company shall assist such broker-dealer in complying
with the requirements of the NASD Rules, including,  without limitation,  by (A)
engaging a "qualified  independent  underwriter" (as defined in Rule 2720(b)(15)
of the NASD Rules (or any successor  provision  thereto)) to  participate in the
preparation  of  the  Registration   Statement   relating  to  such  Registrable
Securities,  to exercise usual standards of due diligence in respect thereof and
to recommend  the public  offering  price of such  Registrable  Securities,  (B)
indemnifying  such  qualified  independent  underwriter  to  the  extent  of the
indemnification of underwriters  provided in Section 5 hereof, and (C) providing
such  information  to such  broker-dealer  as may be  required in order for such
broker-dealer to comply with the requirements of the NASD Rules.

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

     (a) It shall be a condition  precedent to the obligations of the Company to
complete  the  registration  pursuant  to this  Agreement  with  respect  to the
Registrable Securities


                                      -8-


<PAGE>


of a particular  Investor that such  Investor  shall furnish to the Company such
information  regarding  itself,  the  Registrable  Securities held by it and the
intended method of disposition of the Registrable Securities held by it as shall
be reasonably required to effect the registration of such Registrable Securities
and shall execute such  documents in connection  with such  registration  as the
Company  may  reasonably  request.  As  least  seven  days  prior  to the  first
anticipated filing date of the Registration Statement,  the Company shall notify
each Investor of the  information  the Company  requires from each such Investor
(the  "Requested  Information")  if such  Investor  elects  to  have  any of its
Registrable Securities included in the Registration  Statement.  If at least two
business days prior to the anticipated  filing date the Company has not received
the Requested Information from an Investor (a "Non-Responsive  Investor"),  then
the Company may file the Registration  Statement without  including  Registrable
Securities of such  Non-Responsive  Investor and have no further  obligations to
the Non-Responsive Investor;

     (b) Each Investor by its acceptance of the Registrable Securities agrees to
cooperate with the Company in connection  with the preparation and filing of the
Registration Statement hereunder,  unless such Investor has notified the Company
in writing of its election to exclude all of its Registrable Securities from the
Registration Statement; and

     (c) Each Investor  agrees that, upon receipt of any notice from the Company
of the occurrence of any event of the kind described in Section 3(e) or 3(f), it
shall immediately discontinue its disposition of Registrable Securities pursuant
to the Registration  Statement  covering such Registrable  Securities until such
Investor's  receipt of the  copies of the  supplemented  or  amended  Prospectus
contemplated  by Section 3(e) and, if so directed by the Company,  such Investor
shall  deliver to the Company (at the  expense of the  Company) or destroy  (and
deliver  to the  Company  a  certificate  of  destruction)  all  copies  in such
Investor's  possession,  of the Prospectus covering such Registrable  Securities
current at the time of receipt of such notice.

     5.  Expenses  of  Registration.   All  expenses,  other  than  underwriting
discounts and commissions, incurred in connection with registrations, filings or
qualifications  pursuant to Section 3, but including,  without  limitation,  all
registration,  listing,  and qualifications  fees,  printing and engraving fees,
accounting fees, and the fees and disbursements of counsel for the Company,  and
the   reasonable   fees  of  one  firm  of   counsel   to  the   holders   of  a
majority-in-interest  of  the  Registrable  Securities  shall  be  borne  by the
Company.

     6. Indemnification and Contribution.

     (a) The Company  shall  indemnify  and hold harmless each Investor and each
underwriter,   if  any,  which   facilitates   the  disposition  of  Registrable
Securities,  and each of their respective officers and directors and each person
who controls  such Investor or  underwriter  within the meaning of Section 15 of
the  Securities  Act or Section 20 of the  Exchange  Act (each such person being
sometimes  hereinafter referred to as an "Indemnified  Person") from and against
any losses,  claims,  damages or  liabilities,  joint or several,  to which such
Indemnified  Person may become  subject under the  Securities  Act or otherwise,
insofar as such losses,  claims,  damages or liabilities  (or actions in respect
thereof)  arise out of or are


                                      -9-


<PAGE>


based upon an untrue  statement or alleged  untrue  statement of a material fact
contained in any  Registration  Statement or an omission or alleged  omission to
state therein a material fact required to be stated therein or necessary to make
the statements  therein,  not  misleading,  or arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
Prospectus  or an omission or alleged  omission to state therein a material fact
required to be stated  therein or necessary to make the statements  therein,  in
the light of the circumstances  under which they were made, not misleading;  and
the  Company  hereby  agrees  to  reimburse  such  Indemnified  Person  for  all
reasonable  legal  and  other  expenses  incurred  by  them in  connection  with
investigating  or defending  any such action or claim as and when such  expenses
are  incurred;  provided,  however,  that the Company shall not be liable to any
such  Indemnified  Person in any such  case to the  extent  that any such  loss,
claim,  damage  or  liability  arises  out of or is  based  upon  (i) an  untrue
statement  or  alleged  untrue  statement  made in, or an  omission  or  alleged
omission from, such Registration Statement or Prospectus in reliance upon and in
conformity with written information furnished to the Company by such Indemnified
Person  expressly  for use therein or (ii) in the case of the  occurrence  of an
event of the type specified in Section 3(e), the use by the  Indemnified  Person
of an outdated or  defective  Prospectus  after the Company has provided to such
Indemnified  Person an updated  Prospectus  correcting  the untrue  statement or
alleged  untrue  statement or omission or alleged  omission  giving rise to such
loss, claim, damage or liability.

     (b)  Indemnification  by the  Investors  and  Underwriters.  Each  Investor
agrees,  as a consequence of the inclusion of any of its Registrable  Securities
in a Registration Statement, and each underwriter, if any, which facilitates the
disposition  of  Registrable   Securities  shall  agree,  as  a  consequence  of
facilitating  such  disposition  of  Registrable  Securities,  severally and not
jointly,  to  (i)  indemnify  and  hold  harmless  the  Company,  its  directors
(including any person who, with his or her consent, is named in the Registration
Statement  as a director  nominee of the  Company),  its  officers  who sign any
Registration  Statement and each person, if any, who controls the Company within
the  meaning  of either  Section 15 of the  Securities  Act or Section 20 of the
Exchange Act,  against any losses,  claims,  damages or liabilities to which the
Company or such other persons may become  subject,  under the  Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect  thereof) arise out of or are based upon an untrue  statement or alleged
untrue statement of a material fact contained in such Registration  Statement or
Prospectus or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the  statements  therein  (in light of the  circumstances  under which they were
made,  in the  case of the  Prospectus),  not  misleading,  in each  case to the
extent,  but only to the extent,  that such untrue  statement or alleged  untrue
statement  or omission  or alleged  omission  was made in  reliance  upon and in
conformity with written  information  furnished to the Company by such holder or
underwriter  expressly for use therein,  and (ii)  reimburse the Company for any
legal or other expenses incurred by the Company in connection with investigating
or defending any such action or claim as such expenses are incurred.

     (c) Notice of  Claims,  etc.  Promptly  after  receipt  by a party  seeking
indemnification  pursuant to this Section 6 (an "Indemnified  Party") of written
notice of any  investigation,  claim,  proceeding  or other action in respect of
which  indemnification is being


                                      -10-


<PAGE>


sought (each, a "Claim"),  the Indemnified Party promptly shall notify the party
against  whom  indemnification  pursuant to this  Section 6 is being sought (the
"Indemnifying Party") of the commencement thereof; but the omission to so notify
the Indemnifying Party shall not relieve it from any liability that it otherwise
may have to the Indemnified  Party,  except to the extent that the  Indemnifying
Party is materially  prejudiced and forfeits  substantive rights and defenses by
reason  of such  failure.  In  connection  with any  Claim as to which  both the
Indemnifying Party and the Indemnified Party are parties, the Indemnifying Party
shall be entitled to assume the defense thereof.  Notwithstanding the assumption
of the defense of any Claim by the  Indemnifying  Party,  the Indemnified  Party
shall have the right to employ  separate legal counsel and to participate in the
defense of such Claim,  and the  Indemnifying  Party  shall bear the  reasonable
fees,  out-of-pocket  costs and expenses of such  separate  legal counsel to the
Indemnified Party if (and only if): (x) the Indemnifying Party shall have agreed
to pay  such  fees,  costs  and  expenses,  (y) the  Indemnified  Party  and the
Indemnifying  Party shall reasonably have concluded that  representation  of the
Indemnified Party by the Indemnifying  Party by the same legal counsel would not
be  appropriate  due to actual or, as reasonably  determined by legal counsel to
the Indemnified Party,  potentially  differing interests between such parties in
the  conduct of the  defense of such  Claim,  or if there may be legal  defenses
available to the  Indemnified  Party that are in addition to or  disparate  from
those available to the Indemnifying  Party, or (z) the Indemnifying  Party shall
have failed to employ legal counsel  reasonably  satisfactory to the Indemnified
Party within a reasonable  period of time after  notice of the  commencement  of
such  Claim.  If  the  Indemnified  Party  employs  separate  legal  counsel  in
circumstances  other than as described  in clauses  (x),  (y) or (z) above,  the
fees, costs and expenses of such legal counsel shall be borne exclusively by the
Indemnified  Party.  Except as provided above, the Indemnifying Party shall not,
in connection  with any Claim in the same  jurisdiction,  be liable for the fees
and  expenses  of more  than  one  firm of  counsel  for the  Indemnified  Party
(together with appropriate  local counsel).  The  Indemnifying  Party shall not,
without the prior written consent of the Indemnifying Party (which consent shall
not unreasonably be withheld),  settle or compromise any Claim or consent to the
entry of any  judgment  that does not  include an  unconditional  release of the
Indemnifying Party from all liabilities with respect to such Claim or judgment.

     (d) Contribution.  If the indemnification provided for in this Section 6 is
unavailable  to or  insufficient  to hold harmless an  Indemnified  Person under
subsection  (a) or (b)  above in  respect  of any  losses,  claims,  damages  or
liabilities  (or actions in respect  thereof)  referred  to  therein,  then each
Indemnifying  Party  shall  contribute  to the  amount  paid or  payable by such
Indemnified Party as a result of such losses, claims, damages or liabilities (or
actions in respect  thereof) in such proportion as is appropriate to reflect the
relative fault of the Indemnifying Party and the Indemnified Party in connection
with the statements or omissions which resulted in such losses,  claims, damages
or liabilities  (or actions in respect  thereof);  as well as any other relevant
equitable  considerations.  The relative  fault of such  Indemnifying  Party and
Indemnified  Party shall be  determined  by reference  to,  among other  things,
whether the untrue or alleged untrue statement of a material fact or omission or
alleged  omission to state a material  fact relates to  information  supplied by
such Indemnified  Party or by such Indemnified  Party, and the parties' relative
intent,  knowledge,  access to information and opportunity to correct or prevent
such  statement or omission.  The parties hereto agree that it


                                      -11-


<PAGE>


would not be just and  equitable if  contribution  pursuant to this Section 6(d)
were  determined  by  pro  rata  allocation   (even  if  the  Investors  or  any
underwriters were treated as one entity for such purpose) or by any other method
of  allocation  which  does not take  account  of the  equitable  considerations
referred to in this Section 6(d).  The amount paid or payable by an  Indemnified
Party as a result of the losses,  claims,  damages or liabilities (or actions in
respect thereof) referred to above shall be deemed to include any legal or other
fees or expenses  reasonably  incurred by such  indemnified  party in connection
with  investigating  or defending any such action or claim.  No person guilty of
fraudulent  misrepresentation  (within  the  meaning  of  Section  11(f)  of the
Securities  Act) shall be entitled to  contribution  from any person who was not
guilty of such  fraudulent  misrepresentation.  The obligations of the Investors
and any  underwriters  in this  Section 6(d) to  contribute  shall be several in
proportion  to  the   percentage  of   Registrable   Securities   registered  or
underwritten, as the case may be, by them and not joint.

     (e)  Notwithstanding  any other  provision  of this  Section 6, in no event
shall any (i)  Investor be required to  undertake  liability to any person under
this Section 6 for any amounts in excess of the dollar amount of the proceeds to
be  received  by such  Investor  from  the sale of such  Investor's  Registrable
Securities  (after  deducting  any fees,  discounts and  commissions  applicable
thereto)  pursuant to any  Registration  Statement under which such  Registrable
Securities are to be registered under the Securities Act and (ii) underwriter be
required  to  undertake  liability  to any Person  hereunder  for any amounts in
excess of the aggregate  discount,  commission or other compensation  payable to
such underwriter with respect to the Registrable  Securities  underwritten by it
and distributed pursuant to the Registration Statement.

     (f) The  obligations  of the  Company  under  this  Section  6 shall  be in
addition  to  any  liability  which  the  Company  may  otherwise  have  to  any
Indemnified  Person and the  obligations  of any  Indemnified  Person under this
Section 6 shall be in addition to any liability  which such  Indemnified  Person
may otherwise have to the Company.  The remedies  provided in this Section 6 are
not exclusive and shall not limit any rights or remedies  which may otherwise be
available to an indemnified party at law or in equity.

     7. Rule 144. With a view to making  available to the Investors the benefits
of Rule 144 under the  Securities Act or any other similar rule or regulation of
the Commission  that may at any time permit the Investors to sell  securities of
the Company to the public without  registration ("Rule 144"), the Company agrees
to:

     (a) comply with the provisions of paragraph (c)(1) of Rule 144; and

     (b) file with the  Commission  in a timely  manner  all  reports  and other
documents  required to be filed by the  Company  pursuant to Section 13 or 15(d)
under the  Exchange  Act;  and,  if at any time it is not  required to file such
reports but in the past had been required to or did file such reports,  it will,
upon the request of any Holder, make available other information as required by,
and so long as necessary to permit sales of, its Registrable Securities pursuant
to Rule 144.


                                      -12-


<PAGE>


     8.  Assignment.  The  rights  to  have  the  Company  register  Registrable
Securities  pursuant to this Agreement  shall be  automatically  assigned by the
Investors to any transferee of all or any portion of such  securities (or all or
any portion of any  Debenture  of the  Company  which is  convertible  into such
securities)  of  Registrable  Securities  only if:  (a) the  Investor  agrees in
writing with the  transferee  or assignee to assign such  rights,  and a copy of
such agreement is furnished to the Company  within a reasonable  time after such
assignment,  (b) the Company is, within a reasonable time after such transfer or
assignment,  furnished  with written  notice of (i) the name and address of such
transferee  or  assignee  and (ii) the  securities  with  respect  to which such
registration rights are being transferred or assigned, (c) immediately following
such transfer or  assignment,  the  securities so transferred or assigned to the
transferee or assignee constitute  Restricted  Securities,  and (d) at or before
the time the Company  received the written notice  contemplated by clause (b) of
this sentence the  transferee or assignee  agrees in writing with the Company to
be bound by all of the provisions contained herein.

     9. Amendment and Waiver. Any provision of this Agreement may be amended and
the  observance  thereof  may be waived  (either  generally  or in a  particular
instance  and either  retroactively  or  prospectively),  only with the  written
consent of the  Company and  Investors  who hold a  majority-in-interest  of the
Registrable Securities. Any amendment or waiver effected in accordance with this
Section 9 shall be binding upon each Investor and the Company.

     10. Miscellaneous.

     (a) A person  or  entity  shall be  deemed  to be a holder  of  Registrable
Securities  whenever  such  person or entity  owns of  record  such  Registrable
Securities.  If  the  Company  receives  conflicting  instructions,  notices  or
elections  from  two or more  persons  or  entities  with  respect  to the  same
Registrable  Securities,  the Company shall act upon the basis of  instructions,
notice  or  election  received  from the  registered  owner of such  Registrable
Securities.

     (b) If,  after  the date  hereof,  the  Company  grants to any  Person  any
registration  Rights  with  respect  to any  Company  securities  which are more
favorable to such other Person than those provided in this  Agreement,  then the
Company  forthwith  shall grant (by means of an amendment  to this  Agreement or
otherwise) identical registration rights to all Investors hereunder.

     (c) Notices required or permitted to be given hereunder shall be in writing
and shall be deemed to be sufficiently given when personally delivered (by hand,
by courier, by telephone line facsimile transmission, receipt confirmed) or sent
by certified mail, return receipt requested,  properly addressed and with proper
postage pre-paid (i) if to the Company, to COMPOSITECH LTD., 120 Ricefield Lane,
Hauppauge,  New York 11788, ATT: Samuel S. Gross, with a copy to Donovan Leisure
Newton & Irvine, 30 Rockefeller  Plaza, New York, New York 10112, ATT: Edward F.
Cox, (ii) if to the Initial Investor, at the address set forth in the Securities
Purchase  Agreement and (iii) if to any other Investor,  at such address as such
Investor shall have provided in writing to the Company, or at such other address
as each such party  furnishes  by notice given in  accordance  with this Section
10(b), and shall be effective,


                                      -13-


<PAGE>


when  personally  delivered,  upon receipt and, when so sent by certified  mail,
four calendar days after deposit with the United States Postal Service.

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

     (e) This Agreement  shall be governed by and interpreted in accordance with
the  laws  of the  State  of New  York.  Each  of the  parties  consents  to the
jurisdiction  of the federal  courts whose  districts  encompass any part of the
City of New York or the state  courts of the  State of New York  sitting  in the
City of New York in connection with any dispute arising under this Agreement and
hereby waives,  to the maximum extent permitted by law, any objection  including
any  objection  based on  forum  non  conveniens,  to the  bringing  of any such
proceeding in such jurisdictions.

     (f)  The  remedies  provided  in  this  Agreement  are  cumulative  and not
exclusive of any remedies provided by law. If any term,  provision,  covenant or
restriction of this Agreement is held by a court of competent jurisdiction to be
invalid, illegal, void or unenforceable,  the remainder of the terms, provision,
covenants  and  restrictions  set forth  herein  shall  remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their best efforts to find and employ an  alternative  means to
achieve the same or substantially  the same result as that  contemplated by such
term, provision,  covenant or restriction.  It is hereby stipulated and declared
to be the  intention of the parties that they would have  executed the remaining
terms, provisions, covenants and restrictions without including any of such that
may be hereafter declared invalid, illegal, void or unenforceable.

     (g) The  Company  shall not enter into any  agreement  with  respect to its
securities  that is  inconsistent  with the  rights  granted  to the  holders of
Registrable  Securities  in this  Agreement  or  otherwise  conflicts  with  the
provisions  hereof.  The  Company  is not  currently  a party  to any  agreement
granting any  registration  rights with respect to any of its  securities to any
person which  conflicts  with the Company's  obligations  hereunder or gives any
other party the right to include any  securities in any  Registration  Statement
filed  pursuant  hereto,  except  for such  rights  and  conflicts  as have been
irrevocably  waived.  Without limiting the generality of the foregoing,  without
the written  consent of the  Holders of a majority in number of the  Registrable
Securities, the Company shall not grant to any person the right to request it to
register any of its  securities  under the  Securities  Act unless the rights so
granted  are  subject  in all  respect  to the prior  rights of the  holders  of
Registrable  Securities  set forth herein,  and are not otherwise in conflict or
inconsistent with the provisions of this Agreement.

     (h) This  Agreement  constitutes  the entire  agreement  among the  parties

                               SECURITY AGREEMENT


     SECURITY AGREEMENT,  dated as of July 18, 1997, made by Compositech Ltd., a
Delaware corporation (the "Grantor") in favor of __________________________ (the
"Secured Party").

                              W I T N E S S E T H :

     WHEREAS,  the Grantor has entered  into a  Securities  Purchase  Agreement,
dated as of July 18, 1997, with the Secured Party (said Agreement,  as it may be
amended or otherwise modified from time to time, being the "Securities  Purchase
Agreement" and all capitalized  terms used but not defined having the respective
meanings assigned to them in the Securities Purchase Agreement); and

     WHEREAS, it is a condition precedent to the purchase of the Debentures that
the Grantor shall have entered into this Agreement;

     NOW, THEREFORE, in consideration of the premises and in order to induce the
Secured  Party to purchase the  Debentures  the Grantor  hereby  agrees with the
Secured Party as follows:

     1. Defined Terms. As used in this  Agreement,  the following terms have the
meanings  specified  below (such meanings  being equally  applicable to both the
singular and plural forms of the terms defined):

          "Collateral"  has the  meaning  assigned  to such term in Section 2 of
     this Agreement.

          "Contracts" has the meaning assigned to such term in Section 3 of this
     Agreement.

          "Equipment"  means any "equipment," as such term is defined in Section
     9-109(2) of the UCC,  hereafter  acquired by the Grantor  with the proceeds
     from the sale by the Grantor to the  Secured  Party of the  Debentures  (as
     shall be listed by the  Grantor  on an  amendment  to  Schedule  II of this
     Agreement immediately upon Grantor's acquisition of such Equipment) and any
     and all additions,  substitutions and replacements of any of the foregoing,
     wherever  located,  together  with  all  attachments,   components,  parts,
     equipment and accessories installed thereon or affixed thereto.

          "Proceeds"  means  "proceeds,"  as such  term is  defined  in  Section
     9-306(1) of the UCC, and, in any event, includes,  without limitation,  (i)
     any  and  all  proceeds  of or  distributions  pursuant  to any  insurance,
     indemnity,

     surety,  warranty or guaranty payable to the Grantor from time to time with
     respect to any of the  Collateral,  (ii) any and all  payments (in any form
     whatsoever)  made or due and  payable to the  Grantor  from time to time in
     connection  with any  requisition,  confiscation,  replevin,  condemnation,
     seizure or forfeiture of all or any part of the Collateral by any public or
     governmental  authority  (or any person acting under color of any public or
     governmental  authority),  and (iii) any and all other amounts from time to
     time paid or payable under or in connection with any of the Collateral.

          "UCC" means the Uniform  Commercial Code as the same may, from time to
     time,  be in effect in the State of New  York;  provided,  however,  in the
     event that,  by reason of  mandatory  provisions  of law, any or all of the
     attachment,  perfection  or priority  of the Secured  Party and the Secured
     Party's  security  interest  in any  Collateral  is governed by the Uniform
     Commercial Code as in effect in a jurisdiction  other than the State of New
     York, the term "UCC" shall mean the Uniform Commercial Code as in effect in
     such other  jurisdiction for purposes of the provisions  hereof relating to
     such attachment, perfection or priority and for purposes of the definitions
     related to such provisions.

     2. Grant of Security Interest.

     As collateral security for the full and prompt payment when due (whether at
stated  maturity,  by acceleration or otherwise) of, and the performance of, all
the  obligations  under,  and to  induce  the  Secured  Party to  purchase,  the
Debentures  pursuant to the Securities  Purchase  Agreement,  the Grantor hereby
assigns, conveys, mortgages,  pledges, hypothecates and transfers to the Secured
Party,  and hereby grants to the Secured Party,  a security  interest in, all of
the Grantor's  right,  title and interest in, to and under the following (all of
which being hereinafter collectively referred to as the "Collateral"):

          (i) all Equipment; and

          (ii) all  Proceeds  of the  foregoing  including  all  accessions  to,
     substitutions and replacements for, and rents, profits and products of, the
     foregoing.

     3. Rights of the Secured Party; Limitations on Secured Party's Obligations.

     (a) It is  expressly  agreed by the Grantor  that,  anything  herein to the
contrary  herein  notwithstanding,  the Grantor  shall remain liable under every

thereunder,  all in accordance  with and pursuant to the terms and provisions of
each such Contract. The Secured Party shall not have any obligation or liability
under any Contract by reason of or arising out of this  Agreement or the receipt
by the Secured Party of any payment  relating to any Contract  pursuant  hereto,
nor shall the Secured Party be required or obligated in any manner to perform or
fulfill any of the obligations of the Grantor under or pursuant to any Contract,
or to  make  any  payment,  or to  make  any  inquiry  as to the  nature  or the
sufficiency of any payment  received by it or the sufficiency of any performance
by any party under any Contract, or to present or file any claim, or to take any
action to collect or enforce any performance or the payment of any amounts which
may have  been  assigned  to it or to which  it may be  entitled  at any time or
times.

     (b) If required by the Secured Party at any time during the  continuance of
any Event of Default,  any Proceeds,  when first  collected by the Grantor,  (as
such term is defined in the Debenture)  received in payment for or on account of
the Equipment,  shall be promptly deposited by the Grantor in precisely the form
received  (with all  necessary  endorsements)  in a special bank account for the
benefit of and maintained by the Secured Party and subject to withdrawal only by
the Secured Party,  as  hereinafter  provided,  and until so deposited  shall be
deemed  to be held in  trust  by the  Grantor  for  and as the  Secured  Party's
property and shall not be commingled  with any of the  Grantor's  other funds or
properties.  Such  Proceeds,  when  deposited,  shall  continue to be collateral
security for all amounts due on and in respect of the  Debentures  and shall not
constitute  payment thereof until applied as hereinafter  provided.  The Secured
Party may apply all or a part of the funds on deposit in said special account to
the  principal  of or  interest  on or  both in  respect  of the  Debentures  in
accordance with the provisions of Section 8(d) hereof and any part of such funds
which  the  Secured  Party  elects  not to so apply  and deem  not  required  as
collateral  security for the Debentures  shall be paid over from time to time by
the Secured Party in its discretion to the Grantor.

                                      -5-


<PAGE>


reasonable  manner which shall not, in the sole  judgment of the Secured  Party,
adversely  affect the Secured Party's rights  hereunder or adversely  affect the
first priority of its lien on and security interest in the Collateral.

     (e) Payment of  Obligations.  The Grantor  will pay  promptly  when due all
taxes,   assessments  and  governmental  charges  or  levies  imposed  upon  the
Collateral  or in respect of its income or profits  therefrom  and all claims of

supplies);   provided,   however,  that  the  Grantor  may  contest  any  taxes,
assessments  and  governmental  changes or levies so  imposed in any  reasonable
manner  which  shall not,  in the  reasonable  judgment  of the  Secured  Party,
adversely affect the first priority of its lien on the security  interest in the
Collateral.

     (f)  Compliance  with Terms of  Contracts.  In all material  respects,  the
Grantor will comply with and perform with all obligations, covenants, conditions
and agreements with respect to every Contract unless, in the reasonable judgment
of the Secured Party, the non-compliance or non-performance of the Grantor shall
not adversely affect the first priority of its lien on the security  interest in
the Collateral.

     (g) Limitation on Liens on Collateral.  The Grantor will not create, permit
or suffer to exist,  and will  defend the  Collateral  against and take all such
other  action as is necessary to remove,  any lien on the  Collateral,  and will
defend the right,  title and interest of the Secured  Party in and to any of the
Grantor's  rights to the Collateral and in and to the Proceeds  thereof  against
the claims and demands of all Persons whomsoever.

     (h) Maintenance of Insurance.  The Grantor will maintain,  with financially
sound and reputable  companies,  insurance  policies (i) insuring the Collateral
against loss by fire, explosion,  theft and such other casualties as are usually
insured against by companies engaged in the same or similar  businesses and (ii)
insuring the Grantor and the Secured Party against liability for personal injury
and property  damage  relating to such  Collateral,  such policies to be in such
amounts and against at least such risks as are  usually  insured  against in the
same general area by companies engaged in the same or a similar business, naming
the Secured Party as an additional  insured with a lender loss payable clause in
favor of the Secured Party on behalf and for the ratable  benefit of the Secured
Party.  The Grantor shall, if so requested by the Secured Party,  deliver to the
Secured Party as often as the Secured Party may reasonably  request, a report of
a reputable  insurance broker  satisfactory to the Secured Party with respect to
the insurance on its Equipment.

     (i) Limitations on Disposition.  In each case, without the prior consent of
the  Secured  Party the Grantor  will not sell,  lease,  transfer  or  otherwise
dispose of any of the Collateral, or attempt or contract to do so.

     (j) Further Identification of Collateral. The Grantor will, if so requested
by the  Secured  Party,  furnish to the Secured  Party,  as often as the Secured
Party  reasonably  requests,  statements and schedules  further  identifying and
describing  the  Collateral  and  such  other  reports  in  connection  with the
Collateral  as the  Secured  Party may  reasonably  request,  all in  reasonable
detail.

     (k)  Notices.  The  Grantor  will  advise the Secured  Party  promptly,  in
reasonable  detail,  (i) of any material lien or claim made or asserted  against
any of the  Collateral,  (ii) of any material  change in the  composition of the
Collateral,  and (iii) of the  occurrence  of any other event which would have a
material  adverse  effect on the  aggregate  value of the  Collateral  or in the
security interests created hereunder.

     (l) Right of Inspection.  Upon  reasonable  notice to the Grantor (unless a
Default or an Event of Default has occurred and is continuing,  in which case no
notice is necessary),  the Secured Party and its representatives shall also have
the right to enter  into and upon any  premises  where any of the  Equipment  is
located for the purpose of inspecting  the same,  observing its use or otherwise
protecting  its  interests  therein.  It  is  understood  and  agreed  that  the
confidentiality  provision  set forth in Section 14 of the  Securities  Purchase
Agreement shall apply to any such inspection.

     (m)  Maintenance  of  Equipment.  The Grantor  will keep and  maintain  the
Equipment in good operating  condition  sufficient for the  continuation  of the
business conducted by the Grantor on a basis consistent with past practices, and
the Grantor will provide all maintenance  and service and all repairs  necessary
for such purpose.

     (n) Continuous  Perfection.  The Grantor will not change its name, identity
or  corporate  structure  in any  manner  which  might  make  any  financing  or
continuation  statement filed in connection herewith seriously misleading within
the  meaning  of  Section  9-402(7)  of the UCC (or any  other  then  applicable
provision of the UCC) unless the Grantor  shall have given the Secured  Party at
least 30 days' prior written  notice thereof and shall have taken all action (or
made  arrangements to take such action  substantially  simultaneously  with such
change  if it is  impossible  to take  such  action  in  advance)  necessary  or
reasonably  requested by the Secured Party to amend such financing  statement or
continuation statement so that it is not seriously misleading.  The Grantor will
not change its  principal  place of business or remove its records or change the
location of the Equipment,  as set forth on Schedule II hereto,  unless it gives
the Secured Party at least 30 days' prior written  notice  thereof and has taken
such action as is necessary to cause the security  interest of the Secured Party
in the Collateral to continue to be perfected.

     6. The Secured Party's Appointment as Attorney-in-Fact.

     (c) The powers  conferred  on the  Secured  Party  hereunder  are solely to
protect the Secured Party's interests in the Collateral and shall not impose any
duty upon it to exercise any such powers. The Secured Party shall be accountable
only for amounts  that it actually  receives as a result of the exercise of such
powers and neither it nor any of its  officers,  directors,  employees or agents
shall be  responsible  to the Grantor for any act or failure to act,  except for
its own gross negligence or willful misconduct.

     (d) The Grantor also  authorizes  the Secured  Party,  at any time and from
time to time upon the  occurrence  and  during  the  continuance  of an Event of
Default,  to execute,  in  connection  with the sale  provided  for in Section 8
hereof,  any  endorsements,  assignments  or other  instruments of conveyance or
transfer with respect to the Collateral.

     7.  Performance by the Secured Party of the Grantor's  Obligations.  If the
Grantor fails to perform or comply with any of its agreements  contained  herein
and the Secured  Party,  as provided for by the terms of this  Agreement,  shall
itself perform or comply,  or otherwise  cause  performance or compliance,  with
such  agreement,  the  reasonable  expenses  of the  Secured  Party  incurred in
connection with such  performance or compliance  shall be payable by the Grantor
to the Secured Party on demand and shall constitute obligations secured hereby.

     8. Remedies, Rights Upon an Event of Default.

     (a) If any Event of Default  shall  occur and be  continuing,  the  Secured
Party may exercise in addition to all other rights and remedies granted to it in
this Agreement and in any other instrument or agreement securing,  evidencing or
relating to the obligations pursuant to the Debentures,  all rights and remedies
of a


                                      -9-

secured party under the UCC.  Without  limiting the generality of the foregoing,
the Grantor  expressly agrees that in any such event the Secured Party,  without
demand  of  performance  or other  demand,  advertisement  or notice of any kind
(except the notice  specified below of time and place of public or private sale)
to or upon the  Grantor  or any  other  Person  (all and each of which  demands,
advertisements  and/or notices are hereby expressly waived to the maximum extent
permitted by the UCC and other applicable law), may forthwith collect,  receive,
appropriate  and realize upon the  Collateral,  or any part thereof,  and/or may
forthwith sell, lease, assign, give an option or options to purchase, or sell or
otherwise  dispose of and deliver said Collateral (or contract to do so), or any
part thereof,  in one or more parcels at public or private sale or sales, at any
exchange or broker's board or any of the Secured Party's offices or elsewhere at
such  prices as it may deem best,  for cash or on credit or for future  delivery
without  assumption  of any credit risk.  The Secured Party shall have the right
upon any such public sale or sales,  and, to the extent  permitted by law,  upon
any such  private  sale or  sales,  to  purchase  the  whole or any part of said
Collateral so sold,  free of any right or equity of redemption,  which equity of
redemption the Grantor  hereby  releases.  The Grantor  further  agrees,  at the
Secured  Party's request to assemble the Collateral and make it available to the
Secured Party at places which the Secured Party shall reasonably select, whether
at the Grantor's  premises or  elsewhere.  The Secured Party shall apply the net
proceeds of any such collection, recovery receipt, appropriation, realization or
sale, as provided in Section 8(d) hereof,  the Grantor  remaining liable for any
deficiency  remaining  unpaid after such  application,  and only after so paying
over such net proceeds  and after the payment by the Secured  Party of any other
amount required by any provision of law,  including  Section  9-504(1)(c) of the
UCC, need the Secured Party account for the surplus,  if any, to the Grantor. To
the maximum extent  permitted by applicable  law, the Grantor waives all claims,
damages,  and demands against the Secured Party arising out of the repossession,
retention or sale of the  Collateral.  The Grantor agrees that the Secured Party
need not give  more that ten  days'  notice of the time and place of any  public
sale or of the time  after  which a  private  sale may take  place and that such
notice is  reasonable  notification  of such  matters.  The Grantor shall remain
liable for any  deficiency  if the  proceeds of any sale or  disposition  of the
Collateral  are  insufficient  to pay all amounts to which the Secured Party are
entitled,  the  Grantor  also  being  liable  for the fees and  expenses  of any
attorneys employed by the Secured Party to collect such deficiency.

     (b)  The  Grantor  also  agrees  to pay all  costs  of the  Secured  Party,
including, without limitation,  attorneys' fees, incurred in connection with the
enforcement of any of its rights and remedies hereunder.

     (c) The Grantor hereby waives  presentment,  demand,  protest or any notice
(to the maximum  extent  permitted by applicable  law) of any kind in connection
with this Agreement or any Collateral.


                                      -10-


<PAGE>


     (d) The Proceeds of any sale,  disposition or other realization upon all or
any part of the  Collateral  shall be  distributed  by the Secured  Party in the
following order of priorities:


     First,  to the payment of the costs and  expenses of such sale,  including,
without  limitation,  all expenses of the Secured Party and its agents including
the fees and expenses of its counsel, and all expenses, liabilities and advances
made or incurred by the Secured  Party in  connection  therewith  or pursuant to
Section 7 hereof;

     Next, to the Secured Party,  for the payment in full of all amounts owed to
the Secured Party by the Grantor and

     Finally,  after payment in full of all amounts owed to the Secured Party by
the Grantor to the payment of the Grantor,  or its successors or assigns,  or to
whomsoever may be lawfully  entitled to receive the same as a court of competent
jurisdiction may direct.

     9.  Limitation on the Secured  Party's Duty in Respect of  Collateral.  The
Secured Party shall not have any duty as to any  Collateral in its possession or
control  or in the  possession  or  control of any agent or nominee of it or any
income thereon or as to the  preservation of rights against prior parties or any
other  rights  pertaining  thereto,  except  that the  Secured  Party  shall use
reasonable  care with respect to the  Collateral in its  possession or under its
control.  Upon request of the Grantor,  the Secured  Party shall account for any
moneys  received by it in respect of any  foreclosure  on or  disposition of the
Collateral.

     10. Notices.  All notices and other  communications  provided for hereunder
shall  be  in  writing  (including   telegraphic,   telex,  telecopy,  or  cable
communication) and mailed, telegraphed, telexed, telecopied, cabled or delivered
by hand,  if to the Grantor or to the Secured Party at the address of such party
specified in the Securities  Purchase  Agreement,  or, as to each party, at such
other address as shall be  designated by such party in a written  notice to each
other party  complying as to delivery with the terms of this  Section.  All such
notices and other  communications  shall,  when  mailed,  telegraphed,  telexed,
telecopied,  cabled or  delivered,  be  effective  when  deposited in the mails,
delivered to the telegraph  company,  confirmed by telex answerback,  telecopied
with  confirmation or receipt,  delivered to the cable company,  or delivered by
hand to the addressee or its agent, respectively.

     11.  Amendments,  Etc.  No  amendment  or waiver of any  provision  of this
Agreement  nor consent to any  departure by the Grantor  therefrom  shall in any
event be effective  unless the same shall be in writing,  approved and signed by
the Secured  Party,  and then any such waiver or consent shall only be effective
in the specific instance and for the specific purpose for which given.

     12. No Waiver; Remedies. (a) No failure on the part of any Secured Party to
exercise,  and no delay in  exercising  any right  hereunder  shall operate as a
waiver thereof;  nor shall any single or partial exercise of any right hereunder
preclude  any other or further  exercise  thereof or the  exercise  of any other
right.  The remedies herein provided are cumulative,  may be exercised singly or
concurrently,  and  are not  exclusive  of any  remedies  provided  by law,  the
Securities Purchase Agreement or the Debentures.

     (b) Failure by the Secured Party at any time or times  hereafter to require
strict  performance by the Grantor or any other person of any of the provisions,
warranties,  terms or conditions  contained in the Securities Purchase Agreement
or the Debentures now or at any time or times hereafter  executed by the Grantor
or any such other  person and  delivered  to any of the Secured  Party shall not
waive,  affect or diminish any right of any of the Secured  Party at any time or
times hereafter to demand strict performance  thereof,  and such right shall not
be deemed to have been  modified or waived by any course of conduct or knowledge
of the Secured Party, or any agent, officer or employee of the Secured Party.

     13. Release of Liens.  Upon payment in full of the principal  amount of and
all accrued and unpaid interest on the Debentures or upon the earlier conversion
of the  Debentures  in full and the full and  indefeasible  satisfaction  of all
other  obligations  to the Secured  Party,  the Secured Party  agrees,  upon the
written  request of the Grantor and at the Grantor's  sole expense,  to execute,
record and file such  instruments  and  perform  such acts as are  necessary  to
effect or evidence the release of the Collateral from the security  interests of
this Security  Agreement  and from any  assignment  or other  security  document
entered into pursuant hereto.

     14.  Successors  and Assigns.  This  Agreement and all  obligations  of the
Grantor  hereunder  shall be  binding  upon the  successors  and  assigns of the
Grantor,  and shall,  together with the rights and remedies of the Secured Party
hereunder,  inure to the benefit of the  Secured  Party and its  successors  and
assigns.

     15.  Governing Law. This  Agreement  shall be governed by, and be construed
and interpreted in accordance  with, the law of the State of New York.  Wherever
possible,  each provision of this Agreement  shall be interpreted in such manner
as to be effective and valid under  applicable law, but if any provision of this
Agreement shall be prohibited by or invalid under applicable law, such provision
shall be  ineffective  only to the extent of such  prohibition or invalidity and
without invalidating the remaining provisions of this Agreement.

     16. Waiver of Jury Trial. The Grantor waives any right it may have to trial
by jury in any action or  proceeding to enforce or defend any rights or remedies
hereunder,  under the Securities Purchase Agreement, the Debentures or any other
document relating to any of the foregoing.

     17.  Further  Indemnification.  The Grantor  agrees to pay, and to save the
Secured  Party  harmless  from,  any and all  liabilities  with  respect  to, or
resulting from any delay in paying,  any and all excise,  sales or other similar
taxes which may be payable or  determined  to be payable  with respect to any of
the Collateral or in connection  with any of the  transactions  contemplated  by
this Agreement.

     18. Section Titles.  The Section titles contained in this Agreement are and
shall be without  substantive  meaning or content of any kind whatsoever and are
not a part of this Agreement.
