                SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     This Prospectus and the documents  incorporated herein by reference contain
forward-looking  statements  within the meaning of Section 27A of the Securities
Act of 1933 (the  "Securities  Act") and Section 21E of the Securities  Exchange
Act of 1934 (the  "Exchange  Act" ) which are not  historical  facts and involve
risks and  uncertainties  that could cause actual  results to differ  materially
from those expected and projected.  These  forward-looking  statements  concern,
among other things,  the Company's  expectations,  plans and  strategies for the
development and  commercialization of products based on its technologies and are
generally identified by the use of such terms as "intends,"  "expects," "plans,"
"projects,"  "estimates,"  "anticipates,"  "should" and  "believes."

     All of such  forward-looking  statements are based on assumptions which the
Company,  as of the  date of this  Prospectus,  believes  to be  reasonable  and
appropriate. The Company cautions, however, that the actual facts and conditions
that may exist in the future could vary  materially  from the assumed  facts and
conditions upon which such forward-looking statements are based.

     The factors  discussed in this Prospectus under "Risk Factors" and in other
documents  and reports  filed by the Company  with the  Securities  and Exchange
Commission  pursuant to the  requirements  of the federal  securities laws could
cause the  actual  facts  and  conditions  that may exist in the  future to vary
materially from the assumed facts and conditions upon which the forward-looking
statements contained herein are based.


                                     THE COMPANY

    The Company is in the business of synthesizing new materials and developing
advanced  production  technology  and  innovative  products  based on  amorphous
(disordered) and related  materials,  with an emphasis on alternative energy and
advanced  information  technologies.   The  Company's  products  and  production
technology  in the  field of  alternative  energy  are  being  manufactured  and
marketed through  alliances  throughout the world with major companies,  such as
General  Motors  Corporation  and  Canon,  Inc.  In  the  field  of  information
technology, the Company's Ovonic phase change erasable optical memory technology
is licensed by major optical  memory disk  manufacturers,  including  Matsushita
Electric Industries Co., Ltd. and Sony Corporation.

    The Company's principal executive offices are located at 1675 West
Maple Road, Troy, Michigan 48084, and its telephone number is (248) 280-1900.


Recent Events

     On April 23, 1998, United Solar Systems Corp. ("United  Solar"),  the
Company's  photovoltaic (solar energy) joint venture with Canon Inc. of Japan,
and Sky Station International, Inc. ("Sky Station") announced the formation of
Sky Solar, L.L.C. to manufacture photovoltaic ("PV") products for stratospheric
platforms and space

                                      5

<PAGE>

satellites.  The venture is owned 60% by United Solar, which is contributing
its proprietary PV technology to the venture, and 40% by Sky Station which is to
provide the funding to optimize United Solar's technology for stratospheric and
space ("strato-space") applications and for construction of a dedicated strato-
space PV production line. In connection with this agreement, substantial amounts
of the funding will be used for the development and construction of the
equipment which will be subcontracted by United Solar to the Company to produce
the PV products for these platforms and satellites.  Final contracts for the
development and construction of this equipment are pending the successful
completion of Sky Station's funding.

     In April 1998, the Company entered into a one-year financing agreement with
Standard Federal Bank for a line of credit of up to $5,000,000.  This financing
bears an interest rate of prime plus 1/2%, is secured by a first interest in the
Company's accounts receivable and inventory and contains certain financial cove-
nants relating to the Company's tangible net worth, working capital and total
debt to tangible net worth.  Also in April 1998, the Company entered into a
$6,000,000 credit arrangement with Finova Capital Corporation, which has two
components.  One component, which has been fully utilized, provided $2,000,000
to refinance existing leased equipment (resulting in $1,200,000 net cash to the
Company), has a three-year term at the expiration of which the Company will be
required to purchase the equipment for 10% of the original cost.  The second
component provides for up to $4,000,000 of financing through December 31, 1998 
for the Company's sale and leaseback of equipment it acquired subsequent to June
30, 1996; at the expiration of the related five-year lease, the Company will be
required to purchase the leased equipment for 10% of the original cost.
 
 

                                RISK FACTORS

    The following  risk factors  should be considered  in  conjunction  with the
other  information  included and  incorporated  by reference in this  Prospectus
before purchasing or otherwise acquiring the Units offered hereby.


History of Losses

    From its founding  through  December 31, 1997,  the Company has incurred net
losses totaling  approximately  $182.9 million.  The Company's ability in future
years to  achieve  profitability  will  depend  largely on  securing  additional
licensing agreements and the successful commercialization of its products as to
which there can be no assurance.


Need to Raise Additional Capital

     The Company has in the past  experienced  substantial  losses and  negative
cash flow from operations and has required  significant  additional financing in
order to pursue the commercialization of products based on its technologies. The
Company  cannot  predict when or if additional  financing  will be needed or, if
needed, in what amounts and may seek additional financing at any time, including
the next 12 months.  There can be no assurance  that such  additional  financing
will be available or that the terms of such additional financing,  

                                         6

<PAGE>

if available, will be acceptable to the Company.  Additional  equity  financing
by the Company may result in substantial dilution to the Company's stockholders,
including purchasers of the Units.

     The  Company  is  currently  in the  process  of  finalizing  a  definitive
agreement  for a  line  of  credit  of up to $5  million  to be  secured  by the
Company's  inventory and accounts  receivable and has line of credit of up to $6
million for the  refinancing  of currently or  previously  leased  manufacturing
equipment, the sale and leaseback of certain other manufacturing equipment owned
by the Company and the purchase of additional  equipment,  no part of which line
has been taken down.

Dependence Upon Licensing Arrangements and Joint Ventures

     In  the  fields  of  consumer  rechargeable  batteries,   electric  vehicle
batteries,  scooter batteries,  photovoltaics and information technologies,  the
Company has entered into licensing and/or joint venture  agreements with estab-
lished industrial  companies.  Any  revenues  or  profits  which may be  derived
by the Company from these licensing and joint venture agreements will be sub-
stantially dependent upon the willingness and ability of the Company's licensees
and joint venture partners to devote their financial resources and manufacturing
and marketing capabilities to commercialize products  based  on  the  Company's
technologies.  There can be no assurance that such financial resources will be
available or that such commercialization will be successful. Certain of the
Company's joint venture and business agreements contain conditions which, if not
satisfied, permit the joint venture or business partner to discontinue such
arrangements.  Many of such conditions are outside of the Company's control and
there can accordingly be no assurance that such conditions will be satisfied.
There are also various business, technological and other uncertainties that
affect the Company and its joint venture partners and licensees. In fields in
which it is not presently a party to joint venture or license agreements, the
Company may be required to enter into collaborative arrangements with
established industry partners to produce products on a commercial scale.  There
can be no assurance that the Company will be able to enter into such
collaborative arrangements.

Concentration of Revenues

     The Company  historically  has entered  into  agreements  with a relatively
small number of major customers  throughout the world.  For the six months ended
December 31, 1997, three major customers--General Motors Corporation,  GM Ovonic
L.L.C. ("GM Ovonic") and G.P.Batteries International, Ltd. ("G.P.  Batteries")--
accounted for approximately 61% of total revenue.  GM Ovonic and GP Batteries
accounted for approximately 56% of total revenue for the year ended June 30,
1997.

Competition

     The Company  and its  affiliates  compete  with firms,  both  domestic  and
foreign,  that  perform  research  and  development,   as  well  as  firms  that
manufacture  and sell  products.  Some  competing  firms are  among the  largest
industrial   companies   in  the  world  and  have   well-established   business
organizations  and product  lines,  extensive  resources and large  research and
development  staffs and  facilities.  There can be no assurance that one or more
such companies will not succeed in developing technologies or products that will
become available for commercial sale prior to the Company's products,  that will
have  performance  superior to the  Company's  products or that would  otherwise
render the Company's products obsolete or non-competitive.
Technology Risks

Technology Risks

     Additional research and development efforts will be required before certain
of the  Company's  products  and  technologies  may  be  manufactured  and  sold
commercially.  There can be no  assurance  that such  research  and  development
efforts  will  be  successful  or that  the  Company  will  be  able to  develop
commercial  applications for its products and  technologies.  The areas in which
the Company is developing  technologies and products are  characterized by rapid
and significant technological change. Rapid technological development may result
in the  Company's  products  becoming  obsolete  or  non-competitive  before the
Company is able to recover any portion of the research and development and other
expenses it has incurred to develop its products and technologies.

Manufacturing Uncertainties

     In order to produce  products on a  commercial  scale,  the Company and its
joint venture  partners and certain of its licensees  will be required to expand
or  establish   manufacturing   capabilities   significantly  greater  than  the
manufacturing  capabilities  currently  being  used to  produce  certain  of the
Company's products. Although substantially all of its joint venture partners and
licensees have  experience in commercial  scale  manufacturing,  the Company has
little such  experience  and there can be no assurance  that the Company or such
other  parties  will  expand  or  establish   manufacturing   capabilities   for
manufacturing the Company's products beyond those presently in existence.

Uncertainty of Market Acceptance

     The  market  prices  for the  Company's  products  may exceed the prices of
competitive  products  based on current  technologies  or new products  based on
technologies  currently  under  development by  competitors.  There  can  be no
assurance that the prices of the Company's products will be perceived by
consumers as cost-effective or that the prices of such products will be
competitive with existing products or with other new products or technologies.


                                         8

Uncertainty of Patents and Protection of Proprietary Technology

     The Company's  ability to compete  effectively will depend, in part, on its
ability to protect and maintain the proprietary nature of its technology.  There
can be no assurance as to the degree of protection  offered by the patents owned
by the Company,  or as to the likelihood that additional  patents will be issued
based upon pending patent applications. Patent applications in the United States
are  maintained in secrecy until patents are issued and the Company,  therefore,
cannot be certain that it was the first creator of the inventions covered by its
patents or pending patent applications,  or that it was the first to file patent
applications for such  inventions.  The high costs of enforcing patent and other
proprietary rights may also limit the degree of protection afforded the Company.
Claims  alleging the  invalidity of the Company's  patents,  such as proceedings
which have been brought in the French and German patent offices  seeking to have
certain of the Company's issued patents nullified,  or other proprietary rights,
even if unfounded,  may have a material adverse effect on the  commercialization
of products or  technologies  based on such  rights.  The Company also relies on
unpatented proprietary technology, and there can be no assurance that others may
not  independently  develop the same or similar  technology or otherwise  obtain
access to the Company's proprietary  technology.  There can be no assurance that
the Company's patents or other proprietary rights will be determined to be valid
or enforceable if challenged in court or administrative  proceedings or that the
Company's patents or other proprietary  rights,  even if determined to be valid,
will be broad  enough in scope to enable the  Company to prevent  third  parties
from producing products using similar technologies or processes.  There can also
be no  assurance  that the Company  will not become  involved  in disputes  with
respect to the patents or  proprietary  rights of third  parties.  See " - Legal
Proceedings." An adverse outcome from such proceedings could subject the Company
to  significant  liabilities  to third parties,  require  disputed  rights to be
licensed from third parties,  prevent the Company from collecting royalties from
licensees  or require  the Company to stop using such technology, any of which
would have a material  adverse effect on the Company's financial condition and
business prospects.

Dependence on Key Personnel

     The Company's  success is highly  dependent on the continued  services of a
limited  number of skilled  managers  and  scientists.  The loss of any of these
individuals  could have a material  adverse effect on the Company.  In addition,
the  success  of  the  Company  will  depend  upon,  among  other  factors,  the
recruitment   and  retention  of  additional   highly  skilled  and  experienced
management and technical  personnel.  There can be no assurance that the Company
will be able to retain  existing  employees or to attract and retain  additional
personnel on acceptable  terms given the competition  for such  personnel in
industry, universities and non-profit research institutions.

Legal Proceedings

     Although  there are no currently  pending  legal  proceedings  to which the
Company is a party  which  management  believes to be  material,  the Company is
involved in legal proceedings  arising in the normal course of business.  Due to
the  inherent  uncertainties  of  legal  proceedings,  the  outcome  of any such
proceedings  could be unfavorable,  and the Company 

                                      9

<PAGE>

may choose to make payments, or enter into other arrangements,  to settle such
proceedings or may be required to pay damages or other expenses, which could
have a material adverse effect on the Company's financial condition or results
of operations. The Company has been subject  to legal  proceedings  in  recent
years  involving  the  validity  and enforceability of certain of its  patents.
While  such  patent-related legal proceedings have been successfully resolved
in favor of the Company,  such proceedings  can require the  expenditure  of
substantial  management  time and financial resources and can adversely affect
the financial performance of the companies involved. There can be no assurance
that the Company will not be a party to other legal proceedings in the future.

Concentration of Ownership

     Mr.  Stanford R. Ovshinsky and his wife,  Dr. Iris M. Ovshinsky  (executive
officers,  directors  and  co-founders  of the Company),  own of record  153,420
shares  and  65,601  shares,  respectively  (or  approximately  69.8% and 29.8%,
respectively),  of the  outstanding shares of Class A Common  Stock,  which are
entitled to 25 votes per share,  as  compared to the Common  Stock which has one
vote per share. Mr. and Dr. Ovshinsky also have the right to acquire 126,082 and
84,055 shares, respectively, of Class A Common Stock pursuant to the exercise of
presently  exercisable  stock options.  Class A Common Stock is convertible into
Common Stock on a share-for-share basis at any time and from time to time at the
option of the holders,  and will be deemed to be so  converted on September  14,
1999, unless such conversion date is extended with the approval of the Company's
stockholders.  As of March 31,  1998,  Mr. Ovshinsky  also had the right to vote
126,500 shares of Common Stock owned by Sanoh Industrial Co., Ltd. which shares,
together  with the  shares of Class A Common  Stock  and 9,989  shares of Common
Stock owned by Mr. and Dr. Ovshinsky,  give Mr. and Dr. Ovshinsky voting control
over outstanding shares representing  approximately 34.5% of the

combined voting power of the Company (approximately 50.5% in the event they
exercise their options to acquire Class A Common Stock).

     Upon completion of this offering,  assuming the sale of all 2,000,000 Units
offered  hereby  (without  giving effect to the exercise of the  Warrants),  the
directors  and executive  officers of the Company will have voting  control over
outstanding shares representing approximately 30.6% of the combined voting power
of the Company.

     The Company may,  from time to time in the future,  grant stock  options or
warrants to Mr. and Dr. Ovshinsky and other directors and executive  officers of
the  Company,  which may  increase  the  combined  voting  power of the  Company
controlled by these persons.

     The Company, the Company's 93.5%-owned subsidiary,  Ovonic Battery Company,
Inc.  ("Ovonic  Battery"),  and  Mr.  Ovshinsky  are  parties  to an  employment
agreement  providing  for Mr.  Ovshinsky's  right to vote the  shares  of Ovonic
Battery  held by the  Company  following  a change in  control  of the  Company,
enabling  Mr.  Ovshinsky to control  Ovonic  Battery and direct its business and
affairs notwithstanding a change in the control of the Company.

     The foregoing  provisions,  together with other provisions of the Company's
Certificate  of  Incorporation  and  Bylaws,  may have the  effect of  deterring
hostile takeovers or delaying or preventing changes in the control or management
of the Company,  including  transactions in 
                                         10

<PAGE>

which  stockholders  might otherwise receive a premium for their shares over
prevailing  market prices.  The Company may, in the future, adopt additional
provisions by amendment of its Certificate of Incorporation or Bylaws or extend
the effectiveness of existing  provisions which could have similar effects.

Possible Volatility of Stock Price

    There has been a history of significant  volatility in the market price of
the Company's Common Stock.  The Company  believes that many factors,  including
actual or anticipated announcements of technological innovations, new commercial
products,  actual or anticipated  changes in laws and governmental  regulations,
disputes  relating  to  patents  or  proprietary  rights,  changes  in  business
practices and other factors may have a significant effect on the market price of
the Company's Common Stock.

Dilution

    The net  tangible  book value per share of Common Stock at December 31, 1997
was $1.80.  Giving  effect to the net  proceeds  from the sale of the  2,000,000
Units  offered  hereby,  the pro forma net  tangible  book value at December 31,
1997,  would  have  been $___ per share  (attributing  no value to the  Warrants
included in the Units).  Purchasers of the Units will, therefore, suffer an
immediate and  substantial  dilution of $____ in the net tangible book value per
share of the Common  Stock from the  offering  price  (attributing  no value to
the Warrants included in the Units). In addition, such purchasers will
experience dilution upon the exercise of outstanding stock options and warrants.

    As of March 31, 1998,  3,166,257  shares of Common  Stock were  reserved for
issuance  pursuant to the  Company's  stock option plans.  In addition,  474,624
shares of Common  Stock were  reserved  for  issuance  upon  exercise of certain
warrants (other than the Warrants), 219,913 shares of Common Stock were reserved
for the conversion of Class A Common Stock into Common Stock and 6,021 shares of
Common  Stock  were   reserved  for   conversion   of   Convertible   Investment
Certificates.   Future  capital  funding  transactions  necessary  to  fund  the
continued operations of the Company may also result in dilution to purchasers of
the Units offered hereby.


                            DESCRIPTION OF WARRANTS

     Each Warrant entitles the holder to purchase one share of Common Stock at
$____  per  share (equal to 135% of the per Unit offering price of the Units
offered hereby) on or prior to January 31, 2000 and at $____ per share (equal to
155% of the per Unit offering price of the Units offered  hereby) at any time
thereafter and on or prior to July 31, 2001, the expiration date of the
Warrants.

     Warrants are issuable  pursuant to a Warrant  Agreement between the Company
and the State  Street  Bank and Trust  Company as  Warrant  Agent.  The  Warrant
Agreement  provides for adjustment of the exercise price of the Warrants and for
change of the  number  and kind of shares  of Common  Stock or other  securities
purchasable  upon exercise of the Warrants upon  occurrence of certain events in
order to protect the warrantholders  against dilution. The 

                                         11

<PAGE>


events requiring such adjustments and changes include stock dividends, split-
ups, combinations and reclassification.


                                USE OF PROCEEDS

    The net  proceeds to the Company from the sale of the Units  offered  hereby
(without  giving  effect to the exercise of the  Warrants)  are  estimated to be
approximately  $__ million.  The Company  intends to invest  approximately  $2.5
million of the net proceeds of this offering in United Solar Systems Corp.,  the
Company's joint venture with Canon Inc. of Japan, for the production and sale of
photovoltaic  products,  and  approximately  $2  million  for  upgrading  Ovonic
Battery's production facilities, with the balance of the net proceeds to be used
for  working  capital,  funding of the  Company's  ongoing  product  development
activities and other general corporate purposes.


                            PLAN OF DISTRIBUTION

     The  2,000,000  Units  offered  hereby  are  being  issued  and sold by the
Company, for whom Janney Montgomery Scott Inc. and Nolan Securities  Corporation
are  acting  as  placement  agents  (the  "Placement  Agents"),   to  "qualified
institutional  buyers" as defined in Rule 144A under the Securities Act of 1933.
No  Units  will be  issued  or sold  to  purchasers  other  than  the  foregoing
institutional  buyers.  The Company has agreed to pay the Placement Agents a fee
equal to six percent of the gross  proceeds to the Company  from the sale of the
Units.  The Company has also agreed to issue the Placement  Agents unit purchase
warrants  (the  "Placement  Agent  Warrants")  to acquire units of the Company's
securities  identical to theUnits offered  hereby, in an amount equal to four
percent of the number of Units sold, at an exercise price per unit equal to 130%
of the per Unit price of the Units offered hereby.  The Placement Agent Warrants
are exercisable at any time, in  whole or in part, for a  four-year period
commencing one year following  the date of issuance.  The Company has granted
demand and piggy-back registration rights, at the Company's expense (limited to
$15,000 with respect to a demand registration), for the securities issuable upon
exercise of the Placement Agent Warrants.

     The Company has agreed to pay or reimburse the  Placement  Agents for their
reasonable expenses incurred in connection with this offering up to a maximum of
$100,000,  of which  $25,000  has been  paid.  The  Company  has also  agreed to
indemnify the Placement Agents and certain related parties against certain civil
liabilities, including liabilities arising under the Securities Act of 1933.

     The  selling  price of the  Units  offered  hereby  will be  determined  by
negotiation  between the Company,  the Placement Agents and the purchasers based
on the trading price of the Company's Common Stock on the NASDAQ National Market
System.

Item 15.    Indemnification of Directors and Officers

            Section 145 of the General  Corporation Law of the State of Delaware
provides that a corporation may indemnify any person who was or is a party to or
is threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative, by
reason of the fact that he is or was a  director,  officer,  employee of another
corporation,  partnership,  joint venture,  trust or other  enterprise,  against
expenses  (including  attorneys'  fees),  judgments,  fines and amounts  paid in
settlement  actually  and  reasonably  incurred by him in  connection  with such
actions,  suit or  proceeding  if he acted  in good  faith  and in a  manner  he
reasonably  believed  to be in or not  opposed  to  the  best  interests  of the
corporation,  and, with respect to any criminal  action or  proceedings,  had no
reasonable cause to believe his conduct was unlawful;  provided,  however,  in a
suit by or in the right of the corporation no  indemnification  shall be made in
respect of any claim,  issue or matter as to which such  person  shall have been
adjudged to be liable to the corporation  unless and only to the extent that the
Court of  Chancery of the State of Delaware or the court in which such action or
suit was brought has determined upon application that,  despite the adjudication
of liability but in view of all of the circumstances of the case, such person is
fairly and  reasonably  entitled to indemnity or such expenses  deemed proper by
the court.

      The Company's Certificate of Incorporation  provides that the Company will
indemnify  its   directors   and  officers  (and  their  heirs,   executors  and
administrators)  against  expenses  reasonably  incurred or imposed upon them in
connection  with or arising out of any action,  suit or proceeding in which they
may be  involved  or to which  they may be made a party  by  reason  of being or
having been a director or officer of the Company,  or, at the Company's request,
any other corporation of which the Company is a stockholder or creditor and from
which they are not entitled to be  indemnified,  except in respect of matters as
to which they are finally


                                     II-1

<PAGE>



adjudged in such action, suit or proceeding to be liable for negligence or mis-
conduct.  In the event of the settlement of any such action, suit or proceeding,
the Company is obligated to provide indemnification only in connection with such
matters covered by the settlement as to which the Company is advised by counsel
that the person to be indemnified did not commit a breach of duty.

      The Company's  Bylaws  provide that the Company will indemnify each person
who is or was a director  or officer of the  Company,  or is or was serving as a
director  or  officer of  another  corporation  or as a trustee or officer of an
association  or trust of which the Company  owns stock or shares or of which the
Company is a creditor,  against all liabilities and expenses at any time imposed
upon or reasonably incurred by such person in connection with, arising out of or
resulting  from any  action,  suit or  proceeding  in which  such  person may be
involved  or with which such  person  may be  threatened,  by reason of his then
serving or theretofore having served as such director, trustee or officer, or by
reason of any alleged act or  omission by him in any such  capacity,  whether or
not he is serving as such director, trustee or officer at the time any or all of
such  liabilities  or expenses  are imposed upon or incurred by him. The matters
covered by the foregoing  indemnity  include  amounts paid by any such person in
compromise or settlement, if such compromise or settlement is approved as in the
best interests of the Company by vote of a majority of  disinterested  directors
then  in  office  or by  vote of a  majority  of the  shares  of  stock  held by
disinterested  stockholders  entitled  to  vote at a  meeting  called  for  such
purpose.  The foregoing  indemnity excludes  liabilities or expenses incurred in
connection  with any matters as to which the person seeking  indemnification  is
finally  adjudged in such action,  suit or  proceeding to be liable by reason of
negligence  or  misconduct in the  performance  of his duties as such  director,
trustee or officer.


Item 16.    Exhibits

      See Exhibit Index.


Item 17.    Undertakings

A.       Rule 415

         The Company hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this Registration Statement to include any mate-
rial information with respect to the plan of distribution not previously dis-
closed in the Registration Statement or any material change to such information
in the Registration Statement.

         (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.

                                    II-2

<PAGE>

         (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.    Incorporation by Reference.

      The Company  hereby  undertakes  that,  for  purposes of  determining  any
liability under the Securities  Act, each filing of the Company's  annual report
pursuant  to  Section  13(a)  or  Section  15(d)  of the  Exchange  Act  that is
incorporated by reference in this Registration Statement 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.

C.    Indemnification.

      Insofar  as  the   indemnification   for  liabilities  arising  under  the
Securities Act may be permitted to directors,  officers and controlling  persons
of the Company pursuant to the foregoing provisions,  or otherwise,  the Company
has been advised that in the opinion of the Securities  and Exchange  Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore,  unenforceable. In the event that a claim for indemnification
against  such  liabilities  (other  than the  payment by the Company of expenses
incurred or paid by a director,  officer or controlling person of the Company 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 Company 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.

D.    Rule 430A

      The Company hereby undertakes that:

      (1) For purposes of determining  any liability under the Securities Act of
1933, the information  omitted from the form of Prospectus filed as part of this
Registration  Statement  in reliance  upon Rule 430A and  contained in a form of
Prospectus  filed by the  Company  pursuant to Rule  424(b)(1)  or (4) or 497(h)
under  the  Securities  Act  shall  be  deemed  to be part of this  Registration
Statement as of the time it was declared effective.

      (2) For purposes of determining  any liability  under the Securities  Act,
each post-effective amendment that contains a form of Prospectus 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.

                                  SIGNATURES

      Pursuant to the  requirements  of the  Securities Act of 1933, as amended,
the Company  certifies that it has  reasonable  grounds to believe that it meets
all of the  requirements  for  filing  on  Form  S-3 and has  duly  caused  this

                     JANNEY MONTGOMERY SCOTT INC.
                     NOLAN SECURITIES CORPORATION



April 22, 1998


Energy Conversion Devices, Inc.
1675 West Maple Road
Troy, Michigan 48084
Attention: Stanford R. Ovshinsky


      Re:   Proposed Limited Public Offering on Form S-3


Ladies and Gentlemen:

            We are pleased to confirm the engagement of Janney  Montgomery Scott
Inc. ("JMS") and Nolan Securities  Corporation  ("Nolan") as co-placement agents
on a "best efforts" basis with respect to the proposed  limited public  offering
(the "Offering") by Energy Conversion Devices,  Inc. ("ECD" or the "Company") of
up to 2 million units  ("Units")  comprised of 2 million shares of the Company's
common stock,  $.01 par value (the "Shares") and 2 million  warrants to purchase
shares of the Company's common stock $.01 par value (the  "Warrants")  solely to
persons who are "qualified institutional buyers" as such term is defined in Rule
144A under the Securities Act.

A.    REGISTRATION STATEMENT

          1. The Units  (including  the  shares of the  Company's  common  stock
issuable upon exercise of the Warrants) will be registered  under the Securities
Act of 1933, as amended (the  "Securities  Act"),  and the Rules and Regulations
promulgated  thereunder,  pursuant  to a  registration  statement  on  Form  S-3
("Registration Statement") or other applicable form, to be prepared and filed by
the Company with the Securities and Exchange Commission (the "Commission").

          2. The Registration  Statement and any amendment thereto ("Amendment")
or other papers or  instruments  relating to the proposed  Offering shall not be
filed with the Commission unless satisfactory, in form and substance, to JMS and
Nolan  and  their  respective  counsel.  JMS and Nolan  shall be  provided  with
sufficient copies of the proposed Registration Statement,


                                   1
<PAGE>



related  Preliminary and Final  Prospectuses and all Exhibits thereto  necessary
for their approval prior to filing with the Commission or  dissemination  to any
party.

B.    BEST EFFORTS PLACEMENT; NO MINIMUM AMOUNT OF UNITS TO
      BE SOLD

            1.  JMS  and  Nolan  shall  act as  co-placement  agents  on a "best
efforts"  basis to sell for the account of the Company up to 2 million  Units to
persons who are "qualified institutional buyers" as such term is defined in Rule
144A under the Securities Act. No minimum number of Units is required to be sold
pursuant to the Offering for the closing to take place.

            2. For acting as placement agents, JMS and Nolan shall receive a fee
equal to six percent  (6%) of the gross  proceeds of the Units sold,  payable to
the order of JMS. In addition,  as set forth in greater  detail  below,  JMS and
Nolan shall receive reimbursement of expenses and JMS shall receive warrants, at
$.01 per warrant, to purchase units identical to the Units. The fee provided for
herein will not apply to any proceeds  received by the Company from  exercise of
the Warrants.


C.    PRICING

            The  offering  price of the Units  (the "Per Unit  Offering  Price")
shall be determined by negotiation by and among the Company,  JMS, Nolan and the
purchasers of the Units based on the closing bid price of the  Company's  common
stock on the Nasdaq  National  Market on the closing date of the  Offering  (the
"Closing Date").


D.    WARRANTS.

            The  Warrants  shall  entitle the holders to purchase  shares of the
Company's  common stock at an exercise  price per share equal to 135% of the Per
Unit Offering  Price on or prior to January 31, 2000,  and at an exercise  price
per share equal to 155% of the Per Unit  Offering  Price at any time  thereafter
and until expiration of the Warrants on July 31, 2001.


E.    EXPENSES OF THE OFFERING

          1.  Irrespective of whether the Offering is  consummated,  the Company
shall  be  responsible  for  and  pay  all  reasonable   expenses  directly  and
necessarily  incurred  in  connection  with  the  offering,  including,  without
limitation:

                                   2

<PAGE>




      (a)   the fees, costs and expenses of the Company's accountants and
            attorneys;

      (b)   the costs of preparing,  delivering  and filing with the  Commission
            the  Registration  Statement,  Preliminary  and Final  Prospectuses,
            Exhibits and related  documents and all amendments  and  supplements
            thereto;  and the costs of delivering  all such documents to JMS and
            Nolan in such reasonable quantities as they may request;

      (c)   the cost of preparing and delivering  certificates  representing the
            Units;

      (d)   the cost and  expenses,  including  legal fees,  of  registering  or
            qualifying the Units for offer and sale under the securities or Blue
            Sky laws of the  various  states in which  JMS and  Nolan  intend to
            offer and sell the Units;

      (e)   NASD filing fees, if any;

      (f)   the fees and  expenses of the  Transfer  Agent and  Registrar of the
            Company's common stock;

      (g)   the fees and expenses of the Warrant Agent for the Warrants;

      (h)   the  reasonable  fees and expenses of legal counsel to JMS and Nolan
            incurred in connection with the Offering;

      (i)   the Company's  own expenses for roadshows and tombstone  advertising
            expenses; and

      (j)   any other  usual  and  customary  expenses  in  connection  with the
            foregoing.

                  The  expenses  of JMS and  Nolan  will be  billed on a monthly
basis and the Company's  reimbursement  obligation  for such expenses  shall not
exceed an  aggregate  of $100,000,  inclusive  of legal fees.  JMS  acknowledges
receipt of an advance against expenses in the amount of $25,000.



F.    JMS AND NOLAN WARRANTS; REGISTRATION RIGHTS


                 At the Closing  Date,  the Company will issue to JMS and Nolan,
or their designees,  warrants (the "Placement Agent Warrants") to purchase units
identical to the Units in an amount equal to four percent (4%) of


                                   3 

<PAGE>



the Units sold in the Offering.  The Placement  Agent Warrants shall expire five
(5) years from the effective date of the Registration Statement and shall be
exercisable commencing one year from the Closing Date, from time to time,  in
whole or in part, prior to the expiration date at an exercise price per unit
equal to one hundred thirty percent (130%) of the Per Unit Offering Price.

               At the written  request of JMS at any time  during the  four-year
exercisable  period,  the Company,  on one occasion,  shall promptly prepare and
file with the Commission a registration  statement (or post-effective  amendment
to the  Registration  Statement) and such other  documents as, in the opinion of
counsel to the Company and counsel to JMS,  shall be required to permit a public
offering  of the  securities  issuable  upon  exercise  of the  Placement  Agent
Warrants and shall use its  reasonable  best efforts to cause such  registration
statement to be declared effective as promptly as possible.  Notwithstanding the
foregoing, ECD may postpone for up to 90 days the filing or the effectiveness of
a registration  statement for a demand  registration if ECD determines that such
demand  registration  would  reasonably be expected to have an adverse effect on
any  proposal  or  plan  by ECD or any of  its  subsidiaries  to  engage  in any
acquisition  or  disposition  of assets  (other than in the  ordinary  course of
business),   merger,   consolidation,   tender  offer,  joint  venture,  license
arrangement or similar transaction. The Company shall pay the initial $15,000 of
the related  fees and  expenses,  other than the fees and expenses of counsel to
JMS and any underwriting or selling  commissions,  and JMS shall pay the excess,
if any, of such fees and expenses.

            After the  Closing  Date,  in the event the  Company  determines  to
register any of its securities  pursuant to a registration  statement filed with
the  Commission  other than on Form S-4 or Form S-8,  the Company will so notify
JMS and Nolan in writing  and JMS and Nolan  shall  have the right,  exercisable
within 30 days  after  such  written  notice,  to  request  that the  securities
issuable  upon  exercise  of the  Placement  Agent  Warrants be included in such
registration statement, which the Company shall so include;  provided,  however,
that if the managing  underwriters of an underwritten public offering advise the
Company that in their  opinion the  securities  requested  for  inclusion by JMS
and/or  Nolan  could  not be  sold in an  orderly  manner  in such  underwritten
offering within a price range acceptable to the Company, then the holders of the
Placement   Agent  Warrants  shall  agree,  at  the  request  of  such  managing
underwriters, not to offer for sale, sell or otherwise dispose of the securities
so  registered  for a period  beginning  seven  days prior to and ending 90 days
after the effective date of the underwritten offering.

            The Company  shall  indemnify  and hold  harmless the holders of the
Placement  Agent  Warrants  whose  securities  are  included  in a  registration
statement filed pursuant to this Section to the identical extent as JMS and


                                   4 

<PAGE>



Nolan are  indemnified  under  Section G hereunder and the Company shall provide
such holders with a written agreement to such effect upon request.

G.    INDEMNIFICATION


            The Company  agrees to indemnify  and hold harmless JMS and/or Nolan
and each  person,  if any,  who  controls JMS and/or Nolan within the meaning of
either Section 15 of the Securities Act or Section 20 of the Securities Exchange
Act of 1934,  as amended  (the  "Exchange  Act"),  from and  against any and all
losses,  claims,  damages and liabilities  (including,  without limitation,  any
legal or other  expenses  reasonably  incurred  by JMS and/or  Nolan or any such
controlling person in connection with defending or investigating any such action
or claim)  caused by any untrue  statement  or  alleged  untrue  statement  of a
material fact contained in the Registration  Statement or any amendment thereof,
any  preliminary or final  prospectus (as amended or supplemented if the Company
shall have furnished any amendments or  supplements  thereto),  or caused by any
omission or alleged  omission to state  therein a material  fact  required to be
stated  therein or  necessary  to make the  statements  therein not  misleading,
except insofar as such losses,  claims, damages or liabilities are caused by any
such untrue  statement or omission or alleged untrue statement or omission based
upon  information  relating to JMS and/or Nolan and  furnished to the Company in
writing by JMS and/or Nolan expressly for use therein.

            JMS and Nolan agree to indemnify and hold harmless the Company,  its
directors,  its officers who sign the 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 to the same  extent as the
foregoing  indemnity from the Company to JMS and Nolan,  but only with reference
to the  failure  of  JMS  or  Nolan  to  comply  with  the  prospectus  delivery
requirements of the federal  securities laws in connection with the Offering and
sale of the Units or to  information  relating to JMS and/or Nolan  furnished to
the Company in writing by JMS and/or  Nolan,  as the case may be,  expressly for
use in the Registration Statement,  any preliminary or final prospectus,  or any
amendments or supplements thereto.

            In case any proceeding  (including any  governmental  investigation)
shall be instituted  involving  any person in respect of which  indemnity may be
sought pursuant to the preceding two paragraphs,  such person (the  "indemnified
party")  shall  promptly  notify the person  against whom such  indemnity may be
sought (the  "indemnifying  party") in writing and the indemnifying  party, upon
request of the indemnified party,  shall retain counsel reasonably  satisfactory
to the indemnified  party to represent the indemnified  party and any others the
indemnifying party may designate in such proceeding and shall pay the fees


                                   5

<PAGE>



and  disbursements  of such  counsel  related  to such  proceeding.  In any such
proceeding,  the  indemnifying  party may assume  the  defense of any action the
subject  of the  first  sentence  of  this  paragraph  with  counsel  reasonably
satisfactory to the indemnified party. In addition,  any indemnified party shall
have the right to retain  its own  counsel,  but the fees and  expenses  of such
counsel  shall  be at the  expense  of such  indemnified  party  unless  (i) the
indemnifying  party and the indemnified  party shall have mutually agreed to the
retention  of such  counsel  or (ii) the named  parties  to any such  proceeding
(including any impleaded  parties) include both the  indemnifying  party and the
indemnified  party and  representation of both parties by the same counsel would
be inappropriate due to actual or potential differing interests between them. It
is  understood  that the  indemnifying  party shall not, in respect of the legal
expenses of any  indemnified  party in connection with any proceeding or related
proceedings  in the same  jurisdiction,  be liable for the fees and  expenses of
more than one  separate  firm (in  addition to any local  counsel)  for all such
indemnified  parties and that all such fees and expenses  shall be reimbursed as
they are incurred. The indemnifying party shall not be liable for any settlement
of any proceeding effected without its written consent, but if settled with such
consent or if there be a final  judgment  for the  plaintiff  not subject to any
appeals,  the indemnifying  party agrees to indemnify the indemnified party from
and against any loss or liability by reason of such  settlement or judgment.  No
indemnifying  party shall,  without the prior written consent of the indemnified
party  (which  shall  not be  unreasonably  withheld  or  delayed),  effect  any
settlement  of any  pending  or  threatened  proceeding  in respect of which any
indemnified  party is or could have been a party and  indemnity  could have been
sought hereunder by such indemnified party,  unless such settlement  includes an
unconditional  release of such  indemnified  party from all  liability on claims
that are the subject matter of such proceeding.


            If the indemnification provided for in the first or second paragraph
of this Section G is unavailable to an indemnified party, then each indemnifying
party under such  paragraph,  in lieu of  indemnifying  such  indemnified  party
thereunder,  shall  contribute to the amount paid or payable by such indemnified
party as a result of such losses,  claims,  damages or  liabilities  (i) in such
proportion as is  appropriate to reflect the relative  benefits  received by the
Company on the one hand and JMS and/or Nolan on the other hand from the offering
of the  Units or (ii) if the  allocation  provided  by  clause  (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the  Company on the one hand and of JMS and/or  Nolan on the other hand
in connection  with the  statements  or omissions  that resulted in such losses,
claims,  damages  or  liabilities,  as  well  as any  other  relevant  equitable
considerations.  The relative  benefits  received by the Company on the one hand
and JMS and/or Nolan on the other hand in connection with the offering of the


                                   6
<PAGE>



Units  shall be  deemed  to be in the  same  respective  proportions  as the net
proceeds from the offering of the Units (before deducting  expenses) received by
the  Company  and the fee paid to JMS and Nolan bear to the  aggregate  offering
price of the Units.  The  relative  fault of the Company on the one hand and JMS
and/or Nolan on the other hand shall be determined by references to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged  omission to state a material  fact  relates to  information
supplied by the Company or by JMS and/or Nolan and the parties' relative intent,
knowledge,  access to information supplied by the Company or by JMS and/or Nolan
and  the  parties'  relative  intent,  knowledge,   access  to  information  and
opportunity to correct or prevent such statement or omission.


            The  Company,  JMS and  Nolan  agree  that it  would  not be just or
equitable if contribution pursuant to this Section G were determined by pro rata
allocation  or by any other method of  allocation  that does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
The amount  paid or payable by an  indemnified  party as a result of the losses,
claims,  damages  and  liabilities  referred  to in  the  immediately  preceding
paragraph  shall be deemed to  include,  subject  to the  limitations  set forth
above, any legal or other expenses reasonably incurred by such indemnified party
in  connection   with   investigating   or  defending   such  action  or  claim.
Notwithstanding  the provisions of this Section G, JMS and/or Nolan shall not be
required to contribute any amount in excess of the aggregate fee paid to JMS and
Nolan by the Company. 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 remedies provided for in this Section G are not exclusive
and shall not limit any rights or remedies  which may  otherwise be available to
any indemnified party at law or in equity.


            The indemnity and contribution  provisions contained in this Section
G shall  remain  operative  and in  full  force  and  effect  regardless  of any
termination of this Agreement.

respect  thereof) arise out of or are based upon any untrue statement or alleged
untrue  statement  of any  materials  fact  contained  in any such  registraiton
statement or any preliminary prospectus or final prospectus  constituting a part
thereof or any  amendment or  supplement  thereto,  or arise out of or are based
upon the omission to state therein a material fact required to be stated therein
or necessary to make the statements  therein not misleading;  and will reimburse
the Distributing Holder and each such controlling person and underwriter for any
legal or other expenses  reasonably  incurred by the Distributing Holder or such
controlling  person or underwriter in connection with investigating or defending
any such loss, claim, damage, liability or action;  provided,  however, that the

                  (ii) The Distributing  Holder will indemnify and hold harmless
the Company,  each of its  directors,  each of its officers who have signed said
registration  statement  and such  officers  who have signed  said  registraiton
statement and such amendments and supplements thereto,  each person, if any, who
controls the Company (within the meaning of the Act) against any losses, claims,
damages or  liabilities  to which the Company or any such  director,  officer or
controlling  person may become subject,  under the Act or otherwise,  insofar as
such losses,  claims,  damages or liabilities arise out of or are based upon any

statement, said preliminary prospectus,  said final prospectus or said amendment
or  supplement  in reliance  upon and in  conformity  with  written  information
furnished by such Distributing  Holder for use in the preparation  thereof;  and
will reimburse the Company or any such director,  officer or controlling  person
for any legal or other expenses  reasonably  incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action.

                  (iii)  Promptly  after receipt by an  indemnified  party under
this subparagraph (c) of notice of the commencement of any

                                     6

<PAGE>



action, such indemnified party will, if a claim in respect thereof is to be made
against  any  indemnifying  party,  give the  indemnifying  party  notice of the
commencement  thereof; but the omission so to notify the indemnifying party will
not relieve it from any  liability  which it may have to any  indemnified  party
otherwise than under this subparagraph (c).

                  (iv)  In  case  any  such   action  is  brought   against  any
indemnified  party,  and it notifies an indemnifying  party of the  commencement
thereof,  the indemnifying party will be entitled to participate in, and, to the
extent that it may wish,  jointly with any other  indemnifying  party  similarly
notified to assume the defense thereof, with counsel reasonably  satisfactory to
such indemnified  party,  and after notice from the  indemnifying  party to such
indemnified  party  of its  election  so to  assume  the  defense  thereof,  the
indemnifying  party  will not be liable to such  indemnified  party  under  this
subparagraph (c) for any legal or other expenses  subsequently  incurred by such
indemnified  party in connection  with the defense thereof other than reasonable
costs of investigation.

                  (d)  SEC  Reports.  So long as the  Placement  Agent  Warrants
remain  outstanding,  the Company shall cause copies of all quarterly and annual
financial  reports  and of the  information,  documents,  and other  reports (or
copies  of such  portions  of any of the  foregoing  as the SEC may by rules and
regulations  prescribe)  which  the  Company  is  required  to file with the SEC
pursuant to Section 13 or 15(d) of the  Securities  Exchange  Act of 19334 ("SEC
Report")  to be mailed to each  Holder at his or her  address  appearing  in the
register  maintained  by the Company for such purpose,  in each case,  within 15
days of filing with the SEC.  If the Company is not subject to the  requirements
of the aforesaid Section 13 or 15(d), the Company shall nevertheless continue to
cause  SEC  Reports,  comparable  to those  which it would be  required  to file
pursuant  to the  aforesaid  Section  13 or  15(d)  if it  were  subject  to the
requirements  of either such  Section,  to be so filed with the SEC (but only if
the SEC permits such  filings) and mailed to each Holder,  in each case,  within
the same time  periods  as would have  applied  (including  under the  preceding
sentence)  had the Company been  subject to the  requirements  of the  aforesaid
Section 13 or 15(d).

      SECTION  4.   Adjustment  of  Exercise  Price  and  Number  of  Underlying
Securities. The number of Underlying Securities purchasable upon the exercise of
the  Placement  Agent  Warrants  and the  Exercise  Price  shall be  subject  to
adjustment from time to time as follows:

                  (a) Stock Splits, Combinations, etc. In case the Company shall
hereafter  (i) pay a dividend  or make a  distribution  on its  Common  Stock in
shares of its capital stock- (whether shares of Common Stock or of capital stock
of any other  class),  (ii)  subdivide its  outstanding  shares of Common Stock,
(iii) combine its  outstanding  shares of Common Stock into a smaller  number of
shares,  or (iv)  issue by  reclassification  of its shams of  Common  Stock any
shares of capital  stock of the Company,  the  Exercise  Price in effect and the
number of Underlying  Shares issuable upon exercise of a Placement Agent Warrant
immediately prior to such action shall be adjusted so that the

                                     7

<PAGE>



Holder shall be entitled to receive the number of shares of capital stock of the
Company at the same  aggregate  Exercise  Price that the Holder would have owned
immediately  following  such  action  had  such  Placement  Agent  Warrant  been
exercised  immediately  prior  thereto.  An  adjustment  made  pursuant  to this
paragraph shall become effective  immediately  after the record date in the case
of a dividend and shall become effective immediately after the effective date in
the case of a subdivision,  combination or reclassification It as a result of an
adjustment made pursuant to this paragraph,  the Holder  thereafter shall become
entitled  to  receive  shares of two or more  classes  of  capital  stock of the
Company,  the Board of Directors of the Company  (whose  determination  shall be
conclusive)  shall  determine  the  allocation  of the adjusted  Exercise  Price
between or among shares of such classes of capital stock.

                  (b) Reclassification  Combinations,  Mergers.  etc, In case of
any  reclassification  or change of outstanding  shares of Common Stock issuable
upon  exercise  of the  Placement  Agent  Warrants  (other  than as set forth in
paragraph  (a) above and other than a change in par value,  or from par value to
no par value,  or from no par value to par value or as a result of a subdivision
or combination),  or in case of any  consolidation or merger of the Company with
or into another  corporation or entity (other than a merger in which the Company
is the continuing  corporation and which does not result in any reclassification
or change of the then outstanding  shares of Common Stock or other capital stock
issuable upon exercise of the Placement Agent  Warrants),  or in the case of any
sale or  conveyance  of all or  substantially  all of the assets of the  Company
followed by a related distribution to holders of shares of Common Stock of cash,
securities  or other  property,  then as a condition  of such  reclassification,
change,  consolidation,  merger,  or  sale  of  assets,  the  Company  or such a
successor corporation or entity, as the case may be, shall forthwith make lawful
and adequate  provision  whereby each Holder shall have the right  thereafter to
receive on exercise of a Placement  Agent  Warrant the kind and amount of shares
of  stock   and   other   securities   and   property   receivable   upon   such
reclassification,  change. consolidation, merger, or sale of assets, by a holder
of the number of shares of Common Stock issuable upon exercise of such Placement
Agent Warrant immediately prior to such reclassification, change, consolidation,
merger,  or sale of assets,  and enter into a supplemental  warrant agreement so
providing. Such provisions shall include provision for adjustments that shall be
as nearly  equivalent as may be practicable to the  adjustments  provided for in
this  Section 4. If the issuer of  securities  deliverable  upon  exercise  of a
Placement Agent Warrant under the supplemental warrant agreement is an affiliate
of the formed or surviving  corporation or other entity,  that issuer shall join
in the supplemental warrant agreement. The above provisions of this subparagraph
(b) shall similarly apply to successive  reclassifications and changes of shares
of Common Stock and to successive consolidations or mergers.

                  (c)  In  the  event  that  at  any  time,  as a  result  of an
adjustment made pursuant to this Section 4, each Holder shall become entitled to
receive any  securities  of the Company  other than the  Underlying  Securities,
thereafter the number of such other  securities so receivable upon exercise of a
Placement  Agent  Warrant and the Price  applicable  to such  exercise  shall be
subject  to  adjustment  from  time to time in a manner  and on terms as  nearly
equivalent as practicable to the provisions with respect to the shares of Common
Stock contained in this Section 4.

                                     8

                  (d) Notice of Change in Exercise Price. Upon any adjustment of
the Exercise Price pursuant to Section 4, the Company shall promptly  thereafter
(i) cause to be prepared a  certificate  of the  President  and Chief  Financial
Officer of the  Company  setting  forth the  adjusted  Exercise  Price  and,  in
reasonable  detail,  the  method of  calculation  and the facts  upon which such
calculations  are based,  and setting forth the number of Underlying  Securities
(or portion thereof) issuable after such adjustment,  which certificate shall be
conclusive  evidence of the  correctness of the matters set forth therein absent
manifest error, provided that if a Holder reasonably requests, the Company shall
engage a firm of independent public accountants of recognized  standing selected
by the Board of Directors of the Company (who may be the regular auditors of the
Company) to prepare and file such  certificate in lieu of the certificate of the
President and Chief Financial  Officer,  in which case such certificate shall be
conclusive  evidence of the matters set forth therein absent manifest error, and
(ii)  send to  each  Holder  at the  address  appearing  on the  registry  books
maintained by the Company  written  notice of such  adjustments  by  first-class
mail, postage prepaid.

                  (e)  Notice of  Certain  Events.  With  respect  to any Notice
Event,  the  Company  shall  cause to be given to each  Holder at such  Holder's
address  appearing on the registry books maintained by the Company,  at least 20
days prior to the applicable record date hereinafter  specified,  or promptly in
the case of events  for which  there is no record  date,  by first  class  mail,
postage  prepaid,  a written notice stating (i) the date as of which the holders
of record of the Common  Stock  entitled  to receive any such  rights,  options,
warrants or distribution is to be determined,  (ii) the initial  expiration date
set forth in any tender offer or exchange  offer for shares of Common Stock,  or
(iii) the date on which any such consolidation,  merger,  conveyance,  transfer,
dissolution,  liquidation  or  winding up is  expected  to become  effective  or
consummated,  and the date as of which it is expected  that holders of record of
shares of Common Stock shall be entitled to exchange such shares for  securities
or  other   property,   if  any,   deliverable   upon   such   reclassification,
consolidation, merger, conveyance, transfer, dissolution, liquidation or winding
up. The  failure to give the notice  required by this  subsection  or any defect
therein  shall not affect the legality or validity of any  distribution,  right,
option, warrant,  consolidation,  merger, conveyance,  transfer, dissolution, or
liquidation  or  winding  up, or the vote upon any  action,  provided  that each
Holder  shall  retain any right to damages from the Company with respect to such
failure.


      SECTION 5. Change in Number of the Underlying  Warrants and the Underlying
Warrant Purchase Price. Under the Warrant Agreement, the Company may elect, upon
any  adjustment of the exercise  price of the Warrants,  to adjust the number of
Warrants  outstanding  in lieu of adjusting the number of shares of Common Stock
purchasable upon the exercise of each Warrant,  so that each Warrant outstanding
after such adjustment  shall represent the right to purchase one share of Common
Stock.  In such a case (i) the  Underlying  Warrant  Purchase Price shall become
that  price  (calculated  to the  nearest  1/1,000  of one cent)  determined  by
multiplying the Underlying Warrant Purchase Price in effect immediately prior to
such  adjustment  by a fraction,  the  numerator  of which shall be the exercise
price of the Warrants in effect  immediately  prior to such  adjustment  and the
denominator of which shall be the exercise price of the Warrants in

                                     9

<PAGE>



effect  immediately after such adjustment and (ii) each Underlying Warrant under
this  Placement  Agent  Warrant  that has not  been  purchased  pursuant  to the
exercise of such Placement  Agent Warrant prior to such adjustment of the number
of Warrants shall become that number of Underlying  Warrants  (calculated to the
nearest  tenth)  determined  by  multiplying  the number one by a fraction.  the
numerator  of  which  shall be the  exercise  price of the  Warrants  in  effect
immediately  prior to such  adjustment and the denominator of which shall be the
exercise price of the Warrants in effect immediately after such adjustment. Upon
each  adjustment  of such  Underlying  warrants  pursuant to this Section 5. the
Company  shall,  as promptly as  practicable,  cause to be  distributed  to each
Holder,  on the date of such  adjustment,  Placement Agent Warrant  Certificates
evidencing,  subject to Section 6(b) hereof, the number of additional Underlying
Warrants to which such Holder  shall be entitled as a result of such  adjustment
or, at the option of the  Company,  cause to be  distributed  to such  Holder in
substitution and replacement for the Placement Agent Warrant  Certificates  held
by such Holder prior to the date of adjustment (and upon surrender  thereof,  if
required by the Company) new Placement Agent Warrant Certificates evidencing the
number of Underlying  Warrants to which such Holder shall be entitled after such
adjustment.

      SECTION 6.  Other-Provisions Relating to Rights of a Holder.

                  (a) Holder not  Stockholder.  A Holder,  as such, shall not be
entitled to vote or receive  dividends  or be deemed a holder of Common Stock or
Warrants of the Company for any purpose,  nor shall  anything  contained in this
Agreement  be  construed  to confer  upon the Holder,  as such,  any rights of a
holder of Common  Stock or  Warrants of the Company or the right to vote or give
or  withhold   consent  to  any  action  by  the  Company   (whether   upon  any
recapitalization,  issue of stock,  reclassification  of  stock,  consolidation,
merger,  conveyance or  otherwise),  receive  notice of meetings or other action
affecting  holders of Common Stock or Warrants  (except for notices provided for
in this Agreement), receive dividends or subscription rights, or otherwise until
the Underlying  Units shall be deliverable  upon exercise of the Placement Agent
Warrant Certificate.

                  (b) Fractional Shares or Warrants.  Anything  contained herein
to the contrary notwithstanding,  the Company shall not be required to issue any
fractional shares of Underlying Shares or Underlying Warrants in connection with
the  exercise  of a Placement  Agent  Warrant  Certificate.  In any case where a
Holder would,  except for the provisions of this Section 6(b), be entitled under
the terms of this  Agreement  to receive a fraction  of an  Underlying  Share or
Underlying  Warrant upon the exercise of a Placement Agent Warrant  Certificate,
the Company shall  round-up to the next highest  Underlying  Shares and the next
highest Underlying Warrant, as the case may be.

                  (c)  Holder  Absolute  Owner.  Prior  to due  presentment  for
registration of transfer of any Placement Agent Warrant Certificate, the Company
may deem and treat the Holder as the absolute owner thereof.


                                     10

<PAGE>

      SECTION 7.   Exchange and Transfer of Placement Agent Warrants

                  (a) Request.  At the request of the Holder,  a Placement Agent
Warrant  Certificate  may be divided split up,  combined or exchanged for one or
more other Placement Agent Warrant Certificates of like tenor to purchase a like
aggregate number of Underlying  Units. The request shall be in writing delivered
to the  Company at its office in Troy,  Michigan  accompanied  by the  Placement
Agent Warrant  Certificate[s] to be so divided,  split up, combined or exchanged
at said office.  Upon any such surrender,  the Company shall execute and deliver
to the person entitled thereto new Placement Agent Warrant  Certificate[s] as so
requested.  The  Company  may  require  the  surrendering  Holder  to  pay a sum
sufficient  to cover  any tax or  governmental  charge  that may be  imposed  in
connection therewith.

                  (b)   Assignment;   Replacement  of  Placement  Agent  Warrant
Certificates.  The  Placement  Agent  Warrants  may  not be  sold,  transferred,
assigned,  or  hypothecated,  in whole or in part, for a period of one year from
the effective date of the Offering,  except to officers of the Placement Agents.
Thereafter,  the Placement Agent Warrants may be sold, transferred,  assigned or
hypothecated, in whole or in part, subject to federal and state securities laws.
Any  permitted  assignment  shall be made by  surrender of the  Placement  Agent
Warrant  Certificate  to the  Company at its  principal  office with the form of
assignment  attached  thereto duly executed and with funds sufficient to pay any
transfer  tax, in which event the Company  shall,  without  charge,  execute and
deliver a new Placement Agent Warrant Certificate in the name of the assignee so
named.  Upon receipt by the Company of evidence  satisfactory to it of the loss,
theft,  destruction or mutilation of a Placement  Agent Warrant  Certificate and
(in  the  case  of  loss,  theft  or  destruction)  of  reasonably  satisfactory
indemnification, and (in the cast of mutilation) upon surrender and cancellation
of such  Placement  Agent  Warrant  Certificate,  the Company  will  execute and
deliver a new Placement Agent Warrant Certificate of like tenor and date and any
such  lost,  stolen or  destroyed  Placement  Agent  Warrant  Certificate  shall
thereupon become void. Any such new Placement Agent Warrant Certificate executed
and delivered shall constitute an additional  contractual obligation on the part
of the Company,  whether or not the Placement Agent Warrant Certificate so lost,
stolen, destroyed or mutilated shall be at any time enforceable by anyone.

      SECTION 8.  Other Matters.

                  (a)  Taxes and  Charges.  The  Company  will from time to time
promptly pay,  subject to the  provisions of paragraph (v) of Section 2(b),  all
taxes and  charges  that may be  imposed  upon the  Company  in  respect  of the
issuance or delivery,  but not the transfer,  of the Placement Agent Warrants or
the Underlying Securities.

                  (b)  Notices to  Company.  Notice or demand  pursuant  to this
Agreement  to be given or made by a Holder to or on the Company  shall be deemed
given or made if delivered or sent by registered or certified mail, postage

           SECTION 2.  Appointment of Warrant Agent. The Company hereby appoints

           (a) A Warrant shall  initially  entitle the Registered  Holder of the

Stock upon the exercise thereof, in accordance with the terms hereof, subject to
modification and adjustment as provided in Section 9 hereof.

           (b)  From  time to  time,  up to the  Warrant  Expiration  Date,  the

<PAGE>



Registered Holder;  (iii) those issued upon any transfer or exchange pursuant to
Section 7 hereof; (iv) those issued in replacement of lost, stolen, destroyed or
mutilated  Warrant  Certificates  pursuant  to Section 8 hereof;  and (v) at the
option  of the  Company,  in  such  form  as may be  approved  by its  Board  of
Directors,  to reflect (a) any  adjustment  or change in the number of shares of
Common Stock  purchasable upon exercise of the Warrants made pursuant to Section
9  hereof  and  (b)  other  modifications  approved  by  Registered  Holders  in
accordance with Section 16 hereof.

           SECTION 4.   Form and Execution of Warrant Certificates.

           (a) The  Warrant  Certificates  shall  be  substantially  in the form
annexed  hereto as Exhibit A (the  provisions  of which are hereby  incorporated
herein) and may have such letters,  numbers or other marks of  identification or
designation and such legends,  summaries or endorsements printed,  lithographed,
engraved or typed  thereon as the Company  may deem  appropriate  and as are not
inconsistent  with the  provisions of this  Agreement,  or as may be required to
comply with any law or with any rule or regulation made pursuant thereto or with
any rule or regulation of any stock exchange or securities  association on which
or through which the Warrants may be listed, or to conform to usage. The Warrant
Certificates  shall be dated the date of issuance  thereof (whether upon initial
issuance, transfer, exchange or in lieu of mutilated, lost, stolen, or destroyed
Warrant Certificates) and issued in registered form.
Warrants shall be numbered serially with the letter W.

           (b) Warrant  Certificates  shall be executed on behalf of the Company
by its  Chairman  of the  Board,  President  or any  Vice  President  and by its
Secretary  or an  Assistant  Secretary,  by manual  signatures  or by  facsimile
signatures  printed  thereon,  shall have  imprinted  thereon a facsimile of the
Company's  seal and shall be  countersigned  by an  authorized  signatory of the
Warrant  Agent.  In case any officer of the Company who shall have signed any of
the Warrant  Certificates  shall cease to be such officer of the Company  before
the date of issuance of the Warrant Certificates and issue and delivery thereof,
such Warrant Certificates may nevertheless be issued and delivered with the same
force and effect as though the person who signed such Warrant  Certificates  had
not ceased to be such  officer of the Company.  After  execution by the Company,
Warrant  Certificates  shall be delivered by the Warrant Agent to the Registered
Holders.

           SECTION 5. Exercise.  Each Warrant may be exercised by the Registered
Holder  thereof  at any  time  after  the  effective  date  of the  Registration
Statement and until the Warrant  Expiration  Date, upon the terms and subject to
the  conditions set forth herein and in the applicable  Warrant  Certificate.  A
Warrant shall be deemed to have been exercised immediately prior to the close of
business on the Exercise Date and the person  entitled to receive the securities
deliverable  upon such exercise  shall be treated for all purposes as the holder
of such securities  upon exercise of the Warrant  Certificate as of the close of
business on the Exercise  Date. As soon as  practicable on or after the Exercise
Date, the Warrant Agent shall deposit the proceeds received from the exercise of
a Warrant,  and promptly  after  clearance of checks  received in payment of the
Exercise Price  pursuant to such  Warrants,  cause to be issued and delivered by
the Transfer Agent, to the person or persons entitled to


                                  3


<PAGE>



receive the same, a certificate or certificates  for the securities  deliverable
upon such exercise (plus a certificate for any remaining unexercised Warrants of
the Registered  Holder, if applicable).  Notwithstanding  the foregoing,  in the
case  of  payment  made  in the  form of a check  drawn  on an  account  of such
investment banks and brokerage houses as the Company shall approve, certificates
shall  immediately be issued without any delay. Upon the exercise of any Warrant
and clearance of the funds received,  the Warrant Agent shall promptly remit the
payment  received for the Warrant to the Company or as the Company may direct in
writing.

           SECTION 6.   Reservation of Shares; Listing; Payment of Taxes; etc.

           (a) The Company  covenants that it will at all times reserve and keep
available out of its authorized Common Stock, solely for the purpose of issuance
upon  exercise of Warrants,  such number of shares of Common Stock as shall then
be issuable upon the exercise of all outstanding Warrants. The Company covenants
that all shares of Common  Stock which shall be  issuable  upon  exercise of the
Warrants  and payment of the  Exercise  Price in  compliance  with this  Warrant
Agreement and the Warrant  Certificate  shall, at the time of delivery,  be duly
and validly issued, fully paid, nonassessable and free from all taxes, liens and
charges  with respect to the issue  thereof  (other than those which the Company
shall promptly pay or discharge).

           (b) The Company  will use  reasonable  efforts to obtain  appropriate
approvals or  registrations  under state "blue sky" securities laws with respect
to the exercise of the Warrants;  provided,  however, that the Company shall not
be  obligated  to file any  general  consent to service of  process,  consent to
taxation or qualify as a foreign  corporation in any jurisdiction.  With respect
to any such  securities  laws,  however,  Warrants may not be  exercised  by, or
shares of Common  Stock issued to, any  Registered  Holder in any state in which
such exercise would be unlawful.

           (c) The Company shall pay all documentary, stamp or similar taxes and
other  governmental  charges that may be imposed with respect to the issuance of
Warrants,  or the  issuance  or  delivery  of any shares  upon  exercise  of the
Warrants; provided, however, that, if shares of Common Stock are to be delivered
in a  name  other  than  the  name  of the  Registered  Holder  of  the  Warrant
Certificate  representing  any Warrant  being  exercised,  then no such delivery
shall be made  unless the  person  requesting  the same has paid to the  Warrant
Agent the amount of transfer taxes or charges incident thereto, if any.

           (d) The Warrant Agent is hereby irrevocably authorized to requisition
the Transfer  Agent from time to time for  certificates  representing  shares of
Common  Stock  required to be issued  upon  exercise  of the  Warrants,  and the
Company  will  authorize  the  Transfer  Agent to  comply  with all such  proper
requisitions.

           SECTION 7.   Exchange and Registration of Transfer.

           Subject to the  restrictions  on  transfer  contained  in the Warrant
Certificates:


                                  4


<PAGE>




           (a)  Warrant   Certificates   may  be  exchanged  for  other  Warrant
Certificates  representing  an equal  aggregate  number  of  Warrants  or may be
transferred in whole or in part.  Warrant  Certificates to be exchanged shall be
surrendered to the Warrant Agent at its Corporate Office,  and upon satisfaction
of the terms and provisions herein,  the Company shall execute,  and the Warrant
Agent shall  countersign,  issue and deliver in exchange  therefor,  the Warrant
Certificate  or  Certificates  which the  Registered  Holder making the exchange
shall be entitled to receive.

           (b) The Warrant  Agent  shall keep books at its  office,  in which it
shall register Warrant  Certificates and the transfer thereof in accordance with
its regular  practice.  Upon due presentment for registration of transfer of any
Warrant  Certificate  at its office,  the Company  shall execute and the Warrant
Agent shall issue and deliver to the  transferee  or  transferees  a new Warrant
Certificate or Certificates representing an equal aggregate number of Warrants.

           (c) The Warrant  Certificates shall be transferable only on the books
of the Company maintained at the office of the Warrant Agent designated for such
purpose  upon  delivery  thereof  duly  endorsed  by the  Holder  or by his duly
authorized  attorney or  representative,  or accompanied  by proper  evidence of
succession,  assignment  or authority to transfer,  which  endorsement  shall be
guaranteed by a member firm of a national securities exchange, a commercial bank
(not a savings bank or a savings and loan  association) or trust company located
in the  United  States or a member of the  National  Association  of  Securities
Dealers, Inc. (hereafter,  "Signatures Guaranteed"). In all cases of transfer by
an attorney,  the original power of attorney,  duly approved, or a copy thereof,
duly certified, shall be deposited and remain with the Warrant Agent. In case of
transfer by executors, administrators, guardians or other legal representatives,
duly  authenticated  evidence of their authority  shall be produced,  and may be
required to be deposited and remain with the Warrant Agent in its discretion.

           (d) A service  charge may be imposed  by the  Warrant  Agent upon the
Registered  Holder for any  exchange  or  registration  of  transfer  of Warrant
Certificates.  The Company may require  payment by a Registered  Holder of a sum
sufficient to cover any tax or other governmental  charge that may be imposed in
connection therewith.

           (e) Prior to due  presentment for  registration of transfer  thereof,
the Company and the Warrant  Agent may deem and treat the  Registered  Holder of
any Warrant Certificate
as  the  absolute  owner  thereof  and  of  each  Warrant   represented  thereby
(notwithstanding  any  notations of ownership or writing  thereon made by anyone
other than a duly  authorized  officer of the Company or the Warrant  Agent) for
all  purposes  and shall not be  affected  by any  notice to the  contrary.  The
Warrants,  which the Company  intends to publicly  offer with the Common  Stock,
will be separately  transferable  immediately  following  the  completion of the
Public Offering.


                                  5


<PAGE>




           SECTION 8. Loss or  Mutilation.  Upon  receipt by the Company and the
Warrant Agent of evidence satisfactory to them of the ownership and loss, theft,
destruction or mutilation of any Warrant Certificate and (in case of loss, theft
or  destruction)  of  indemnity satisfactory  to  them,  and  (in  the  case of
mutilation) upon surrender and cancellation  thereof,  the Company shall execute
and the Warrant  Agent  shall (in the  absence of notice to the  Company  and/or
Warrant  Agent that the  Warrant  Certificate  has been  acquired by a bona fide
purchaser)  countersign  and deliver to the Registered  Holder in lieu thereof a
new Warrant  Certificate of like tenor representing an equal aggregate number of
Warrants. Registered Holders requesting a substitute Warrant Certificate will be
required  to comply  with  such  other  reasonable  regulations,  including  the
submission of an affidavit,  and pay such other  reasonable  charges,  including
payment for a surety bond, as the Warrant Agent may prescribe.

           SECTION 9.   Adjustment of Exercise Price and Number of Shares of 
Common Stock or Warrants.

           (a) Subject to the exceptions  referred to in Section 9(g) below,  in
the event the  Company  shall,  at any time or from time to time  after the date
hereof,  issue any shares of Common Stock as a stock  dividend to the holders of
Common  Stock,  or subdivide or combine the  outstanding  shares of Common Stock
into a greater or lesser number of shares (any such sale, issuance,  subdivision
or combination  being herein called a "Change of Shares"),  then, and thereafter
upon each Change of Shares,  the Exercise Price in effect  immediately  prior to
such  Change of Shares  shall be changed to a price  (including  any  applicable
fraction of a cent)  determined  by  multiplying  the  Exercise  Price in effect
immediately  prior  thereto by a fraction,  the  numerator of which shall be the
number of shares of Common Stock outstanding immediately prior to such Change of
Shares and the  denominator of which shall be the sum of the number of shares of
Common  Stock  outstanding   immediately  after  such  Change  of  Shares.  Such
adjustment shall be made successively whenever such Change of Shares.

           Upon each  adjustment of the Exercise  Price pursuant to this Section
9, the total number of shares of Common Stock  purchasable  upon the exercise of
each Warrant shall (subject to the provisions  contained in Section 9(b) hereof)
be such number of shares  (calculated to the nearest  tenth)  purchasable at the
Exercise Price  immediately  prior to such adjustment  multiplied by a fraction,
the numerator of which shall be the Exercise Price in effect  immediately  prior
to such  adjustment and the  denominator of which shall be the Exercise Price in
effect immediately after such adjustment.

           (b) The Company may elect upon any  adjustment of the Exercise  Price
hereunder,  to  adjust  the  number  of  Warrants  outstanding,  in  lieu of the
adjustment in the number of shares of Common Stock purchasable upon the exercise
of each Warrant as hereinabove  provided, so that each Warrant outstanding after
such adjustment shall represent the right to purchase one share of Common Stock.
Each Warrant held of record prior to such  adjustment  of the number of Warrants
shall  become  that  number  of  Warrants  (calculated  to  the  nearest  tenth)
determined by multiplying  the number one by a fraction,  the numerator of which
shall be the Exercise Price in effect  immediately  prior to such adjustment and
the


                                  6


<PAGE>



denominator  of which shall be the Exercise  Price in effect  immediately  after
such adjustment. Upon each adjustment of the number of Warrants pursuant to this
Section  9,  the  Company  shall,  as  promptly  as  practicable,  cause  to  be
distributed to each Registered  Holder of Warrant  Certificates,  on the date of
such adjustment,  Warrant Certificates evidencing, subject to Section 11 hereof,
the number of  additional  Warrants to which such Holder  shall be entitled as a
result  of such  adjustment  or,  at the  option  of the  Company,  cause  to be
distributed  to such  Holder in  substitution  and  replacement  for the Warrant
Certificates  held by him prior to the date of  adjustment  (and upon  surrender
thereof,  if required by the Company) new Warrant  Certificates  evidencing  the
number of Warrants to which such Holder shall be entitled after such adjustment.

           (c) In case of any reclassification,  capital reorganization or other
similar  change  of  outstanding  shares  of  Common  Stock,  or in  case of any
consolidation or merger of the Company with or into another  corporation  (other
than  a  consolidation  or  merger  in  which  the  Company  is  the  continuing
corporation  and  which  does  not  result  in  any  reclassification,   capital
reorganization  or other change of outstanding  shares of Common  Stock),  or in
case of any sale or  conveyance  to another  corporation  of the property of the
Company  as, or  substantially  as, an entirety  (other  than a  sale/leaseback,
mortgage or other  financing  transaction),  the Company  shall cause  effective
provision  to be made so that each holder of a Warrant  then  outstanding  shall
have the right thereafter,  by exercising such Warrant, to purchase the kind and
number of shares  of stock or other  securities  or  property  (including  cash)
receivable upon such  reclassification,  capital reorganization or other change,
consolidation, merger, sale or conveyance by a holder of the number of shares of
Common  Stock that might  have been  purchased  upon  exercise  of such  Warrant
immediately  prior to such  reclassification,  capital  reorganization  or other
similar change,  consolidation,  merger, sale or conveyance.  Any such provision
shall include  provision for adjustments  that shall be as nearly  equivalent as
may be  practicable  to the  adjustments  provided  for in this  Section  9. The
foregoing  provisions  shall  similarly  apply to successive  reclassifications,
capital  reorganizations and other changes of outstanding shares of Common Stock
and to successive consolidations, mergers, sales or conveyances.

           Neither the  authorization  or issuance by the Company of  additional
shares of its Common Stock,  Class A Common Stock,  par value $.01 per share, or
any new class of  capital  stock,  nor the  modification  of the  voting  rights
attributable thereto, shall be deemed to constitute a reclassification,  capital
reorganization  or other similar change of the outstanding  shares of the Common
Stock for purposes of this Section 9.

           (d)  Irrespective of any adjustments or changes in the Exercise Price
or the  number of  shares  of Common  Stock  purchasable  upon  exercise  of the
Warrants, the Warrant Certificates  theretofore issued, unless the Company shall
exercise its option to issue new Warrant  Certificates  pursuant to Section 3(c)
hereof,  need not be amended or replaced,  but  certificates  thereafter  issued
shall bear an appropriate legend or other notice of any adjustments.



                                  7


<PAGE>



           (e) After each  adjustment  of the  Exercise  Price  pursuant to this
Section  9, the  Company  will  promptly  prepare  a  certificate  signed by the
Chairman or President,  the Secretary or an Assistant Secretary,  of the Company
setting forth: (i) the Exercise Price as so adjusted,  (ii) the number of shares
of Common Stock purchasable upon exercise of each Warrant after such adjustment,
and, if the Company  shall have  elected to adjust the number of  Warrants,  the
number of Warrants to which the Registered  Holder of each Warrant shall then be
entitled,  and  (iii)  a  brief  statement  of the  facts  accounting  for  such
adjustment.  The Company will  promptly file such  certificate  with the Warrant
Agent and cause a brief summary  thereof to be sent by ordinary first class mail
to each Registered Holder at his last address as it shall appear on the registry
books of the Warrant Agent.  The affidavit of an officer of the Warrant Agent or
the Secretary or an Assistant Secretary of the Company that such notice has been
mailed  shall,  in the absence of fraud,  be prima  facie  evidence of the facts
stated therein.

           (f) For  purposes  of Section  9(a) and 9(b)  hereof,  the  following
provisions (A) and (B) shall also be applicable:

                (A) The  number of shares of  Common  Stock  outstanding  at any
           given time shall  include  shares of Common Stock owned or held by or
           for the  account  of the  Company  and the sale or  issuance  of such
           treasury  shares  shall not be  considered  a Change  of  Shares  for
           purposes of said sections.

                (B) No  adjustment  of the  Exercise  Price shall be made unless
           such  adjustment  would  require an  increase or decrease of at least
           $.02 in such price;  provided that any adjustments which by reason of
           this clause (B) are not required to be made shall be carried  forward
           and  shall  be  made  at the  time  of and  together  with  the  next
           subsequent  adjustment  which,  together  with any  adjustment(s)  so
           carried  forward,  shall  require an increase or decrease of at least
           $.02 in the Exercise Price then in effect hereunder.

           (g) As used in this Section 9, the term "Common Stock" shall mean and
include the Common Stock  authorized  on the date of the  original  issue of the
Warrants  and shall also  include any capital  stock of any class of the Company
thereafter authorized which shall not be limited to a fixed sum or percentage in
respect of the rights of the holders  thereof to participate in dividends and in
the  distribution  of assets  upon the  voluntary  liquidation,  dissolution  or
winding up of the Company;  provided,  however,  that the shares  issuable  upon
exercise of the Warrants  shall include only shares of such class  designated in
the Company's  Certificate of  Incorporation  as Common Stock on the date of the
original  issue of the  Warrants  or (i),  in the case of any  reclassification,
change,  consolidation,  merger, sale or conveyance of the character referred to
in Section 9(c) hereof,  the stock,  securities or property provided for in such
section  or  (ii),  in  the  case  of  any  reclassification  or  change  in the
outstanding  shares of Common Stock  issuable upon exercise of the Warrants as a
result of a subdivision  or  combination or consisting of a change in par value,
or from par  value to no par  value,  or from no par  value to par  value,  such
shares of Common Stock as so reclassified or changed.

           (h) Any  determination  as to whether an  adjustment  in the Exercise
Price in effect hereunder is required pursuant to Section 9, or as to the amount
of any such  adjustment,  if  required,  shall be  binding  upon the  Registered
Holders of the  Warrants  and the  Company if made in good faith by the Board of
Directors of the Company.

           (i) If and  whenever  the  Company  shall  declare any  dividends  or
distributions  payable  otherwise than in cash out of earnings or earned surplus
(determined  in  accordance  with  generally  accepted  accounting   principles,
consistently  applied) or grant to all holders of Common Stock, as such,  rights
or warrants to subscribe for or to purchase, or any options for the purchase of,
Common Stock or securities  convertible  into or exchangeable  for or carrying a
right, warrant or option to purchase Common Stock, the Company shall notify each
of the then  Registered  Holders  of the  Warrants  of such  event  prior to its
occurrence  to enable such  Registered  Holders to exercise  their  Warrants and
participate as holders of Common Stock in such event.

           SECTION 10.   Fractional Warrants and Fractional Shares.

           (a) Regardless of whether or not the number of shares of Common Stock
purchasable upon the exercise of each Warrant is adjusted  pursuant to Section 9
hereof,  the Company shall  nevertheless  not be required to issue  fractions of
shares upon exercise of the Warrants or otherwise, or to distribute certificates
that evidence  fractional shares. With respect to any fraction of a share called
for upon any exercise hereof,  the Company shall pay to the Registered Holder an
amount in cash equal to such fraction multiplied by the current market price per
share on the last business day prior to the date of exercise. The current market
price per share shall be determined, with respect to any date, as follows:

           (1) if the Common Stock is listed on a national  securities  exchange
      or admitted to unlisted trading  privileges on such exchange or listed for
      trading on the Nasdaq National  Market System ("NMS"),  the current market
      price per share on any date shall be the last  reported  sale price of the
      Common Stock on such  exchange or system on the last business day prior to
      such date; or

           (2) if the  Common  Stock is  listed in the  over-the-counter  market
      (other than on NMS) or admitted to unlisted  trading  privileges  thereon,
      the current  market  price per share for any date shall be the mean of the
      last  reported  bid and asked prices  reported by the  National  Quotation
      Bureau, Inc. on the last business day prior to such date; or

           (3) if the  Common  Stock is not so listed or  admitted  to  unlisted
      trading  privileges  and bid and asked  prices  are not so  reported,  the
      current  market  price per share  shall be an  amount  determined  in such
      reasonable  manner as may be  prescribed  by the Board of Directors of the
      Company.

           SECTION 11.   Warrant Holders Not Deemed Stockholders.  No
Registered Holder shall, as such, be entitled to vote or to receive dividends or
be deemed  the  holder of Common  Stock  that may at any time be  issuable  upon
exercise of such Warrants for


                                  9


<PAGE>



any purpose  whatsoever,  nor shall  anything  contained  herein be construed to
confer upon the holder of Warrants,  as such, any of the rights of a stockholder
of the Company or any right to vote for the  election of  directors  or upon any
matter submitted to stockholders at any meeting thereof,  or to give or withhold
consent to any corporate  action  (whether upon any  recapitalization,  issue or
reclassification  of  stock,  change  of par  value or change of stock to no par
value,  consolidation,  merger or conveyance or otherwise), or to receive notice
of  meetings,  or to  receive  dividends  or  subscription  rights,  until  such
Registered  Holder shall have  exercised such Warrants and been issued shares of
Common Stock in accordance with the provisions hereof.

           SECTION 12.  Rights of Action.  All rights of action with  respect to
this Agreement are vested in the respective  Registered Holders of the Warrants,
and any Registered Holder of a Warrant,  without consent of the Warrant Agent or
of the  holder of any other  Warrant,  may,  on his own  behalf  and for his own
benefit,  enforce against the Company his right to exercise his Warrants for the
purchase  of  shares of  Common  Stock in the  manner  provided  in the  Warrant
Certificate and this Agreement.

           SECTION 13. Agreement of Warrant Holders.  Every holder of a Warrant,
by his  acceptance  thereof,  consents and agrees with the Company,  the Warrant
Agent and every other holder of a Warrant that:

           (a) The Warrants are  transferable  only on the registry books of the
Warrant  Agent  by  the   Registered   Holder   thereof  in  person  or  by  his
attorney-in-fact duly authorized in writing and only if the Warrant Certificates
representing  such Warrants are  surrendered at the office of the Warrant Agent,
duly endorsed or accompanied by a proper instrument of transfer  satisfactory to
the  Warrant  Agent and the  Company in their  sole  discretion,  together  with
payment of any applicable transfer taxes; and

           (b) The  Company  may deem and  treat the  person  in whose  name the
Warrant  Certificate is registered as the  Registered  Holder thereof and as the
absolute,  true and lawful  owner of the  Warrants  represented  thereby for all
purposes,  and the Company  shall not be affected by any notice or  knowledge to
the contrary, except as otherwise expressly provided in Section 8 hereof.

           SECTION  14.  Cancellation  of Warrant  Certificates.  If the Company
shall  purchase  or acquire  any  Warrant or  Warrants,  whether  upon  exercise
thereof,  open market  purchase,  redemption  or  otherwise,  upon  presentation
thereof to the Warrant Agent,  the Warrant  Certificate or Warrant  Certificates
evidencing  the same shall  thereupon  be  cancelled  by the  Warrant  Agent and
retired. The Warrant Agent shall also cancel Warrant Certificates surrendered to
the Warrant Agent following  exercise of any or all of the Warrants  represented
thereby or delivered to it for transfer, split-up, combination or exchange.

           SECTION 15.   Concerning the Warrant Agent.  The Warrant Agent acts
hereunder as agent and in a ministerial capacity for the Company, and its duties
shall be determined solely by the provisions hereof.  The Warrant Agent shall
not, by issuing and


                                  10


<PAGE>



delivering Warrant Certificates or by any other act hereunder, be deemed to make
any  representations  as to the validity,  value or authorization of the Warrant
Certificates or the Warrants  represented  thereby or of any securities or other
property delivered upon exercise of any Warrant or whether any stock issued upon
exercise of any Warrant is fully paid and nonassessable.

           The Warrant Agent shall account  promptly to the Company with respect
to Warrants  exercised and concurrently pay the Company,  as provided in Section
5, all moneys  received by the Warrant Agent upon the exercise of such Warrants.
The Warrant Agent shall, upon request of the Company from time to time,  deliver
to the Company such complete reports of registered ownership of the Warrants and
such  complete  records of  transactions  with  respect to the  Warrants and the
shares of Common Stock as the Company may request.  The Warrant Agent shall also
make  available to the Company for  inspection by its agents or employees,  from
time to time as it may request,  such  original  books of accounts and record as
may be  maintained  by the Warrant  Agent in  connection  with the  issuance and
exercise of Warrants hereunder, such inspections to occur at the Warrant Agent's
office as specified in Section 17 hereof, during normal business hours.

           The  Warrant  Agent  shall  not at any  time  be  under  any  duty or
responsibility  to any  Registered  Holder  to make  or  cause  to be  made  any
adjustment of the Exercise Price
provided in this  Agreement,  or to determine  whether any fact exists which may
require  any such  adjustments,  or with  respect to the nature or extent of any
such adjustment, when made, or with respect to the method employed in making the
same. It shall not (i) be liable for any recital or statement of facts contained
herein or for any action  taken,  suffered  or omitted by it in  reliance on any
Warrant Certificate or other document or instrument believed by it in good faith
to be  genuine  and to have been  signed or  presented  by the  proper  party or
parties,  (ii) be  responsible  for any  failure  on the part of the  Company to
comply with any of its covenants and obligations  contained in this Agreement or
in any  Warrant  Certificate,  or (iii) be  liable  for any act or  omission  in
connection  with  this  Agreement  except  for its  own  negligence  or  willful
misconduct.

           The Warrant  Agent may at any time consult with counsel  satisfactory
to it (who may be counsel  for the  Company)  and shall  incur no  liability  or
responsibility for any action taken,  suffered or omitted by it in good faith in
accordance with the opinion or advice of such counsel.

           Any notice,  statement,  instruction,  request,  direction,  order or
demand of the Company shall be sufficiently evidenced by an instrument signed by
the Chairman of the Board,  President,  any Vice  President,  its Secretary,  or
Assistant  Secretary  (unless  other  evidence  in  respect  thereof  is  herein
specifically  prescribed).  The Warrant Agent shall not be liable for any action
taken,  suffered or omitted by it in  accordance  with such  notice,  statement,
instruction, request, direction, order or demand believed by it to be genuine.

           The Company agrees to pay the Warrant Agent reasonable  compensation,
as stated in the fee agreement,  for its services  hereunder and to reimburse it
for its reasonable


                                  11


<PAGE>



out-of-pocket  expenses  hereunder;  it further  agrees to indemnify the Warrant
Agent and save it harmless against any and all losses, expenses and liabilities,
including judgments, costs and counsel fees, for anything done or omitted by the
Warrant Agent in the execution of its duties and powers hereunder except losses,
expenses and liabilities  arising as a result of the Warrant Agent's  negligence
or willful misconduct.

           The Warrant  Agent may resign its duties and be  discharged  from all
further duties and liabilities hereunder (except liabilities arising as a result
of the Warrant  Agent's own  negligence  or willful  misconduct),  upon 30 days'
prior  written  notice to the Company and the Company may  discharge the Warrant
Agent from its duties and liabilities hereunder (except liabilities arising as a
result of the Warrant  Agent's own  negligence  or willful  misconduct)  upon 30
days' prior written notice to the Warrant  Agent.  At least 15 days prior to the
date such  resignation  or discharge is to become  effective,  the Warrant Agent
shall cause a copy of such notice of  resignation  or  discharge to be mailed to
the Registered Holder of each Warrant Certificate at the Company's expense. Upon
such  resignation or discharge,  or any inability of the Warrant Agent to act as
such hereunder, the Company shall appoint a new warrant agent in writing. If the
Company shall fail to make such appointment  within a period of 15 days after it
has been notified in writing of such resignation by the resigning Warrant Agent,
or within a period of 15 days after the Warrant  Agent has been  notified by the
Company of such discharge, then the Registered Holder of any Warrant Certificate
may apply to any court of competent  jurisdiction  for the  appointment of a new
warrant  agent.  Any new warrant agent,  whether  appointed by the Company or by
such a court, shall be a bank or trust company having a capital and surplus,  as
shown  by its last  published  report  to its  stockholders,  of not  less  than
$10,000,000 or a stock  transfer  company.  After  acceptance in writing of such
appointment  by the new warrant  agent is received by the  Company,  the Warrant
Agent's  resignation  or discharge  shall be deemed to be effective and such new
warrant  agent  shall be  vested  with  the  same  powers,  rights,  duties  and
responsibilities as if it had been originally named herein as the Warrant Agent,
without any further assurance, conveyance, act or deed; but if for any reason it
shall be necessary  or  expedient to execute and deliver any further  assurance,
conveyance,  act or deed,  the same shall be done at the  expense of the Company
and shall be legally and validly executed and delivered by the resigning Warrant
Agent.  Not later than the effective  date of any such  appointment  the Company
shall file notice thereof with the resigning  Warrant Agent and shall  forthwith
cause a copy of such  notice  to be  mailed  to the  Registered  Holder  of each
Warrant Certificate.

           Any corporation into which the Warrant Agent or any new warrant agent
may be converted or merged or any corporation  resulting from any  consolidation
to which the  Warrant  Agent or any new  warrant  agent  shall be a party or any
corporation  succeeding  to the trust  business of the Warrant  Agent shall be a
successor  warrant agent under this Agreement  without any further act, provided
that such  corporation  is eligible for  appointment as successor to the Warrant
Agent  under the  provisions  of the  preceding  paragraph.  Any such  successor
warrant agent shall  promptly cause notice of its succession as warrant agent to
be  mailed  to  the  Company  and to  the  Registered  Holder  of  each  Warrant
Certificate.



                                  12


<PAGE>



           The Warrant Agent, its subsidiaries and affiliates, and any of its or
their  officers  or  directors,  may buy and  hold or  sell  Warrants  or  other
securities of the Company and otherwise deal with the Company in the same manner
and to the same  extent  and with like  effects  as  though it were not  Warrant
Agent.  Nothing herein shall preclude the Warrant Agent from acting in any other
capacity for the Company or for any other legal entity.

           SECTION 16.   Modification of Agreement.

           (a) Subject to the  provisions  of Section 5(b)  hereof,  the parties
hereto may by  supplemental  agreement  make any changes or  corrections in this
Agreement  (i) that they  shall deem  appropriate  to cure any  ambiguity  or to
correct any  defective or  inconsistent  provision or manifest  mistake or error
herein  contained or (ii) that they may deem  necessary  or desirable  and which
shall not adversely affect the interests of the holders of Warrant Certificates;
provided,  however,  that except as otherwise indicated in this Section and this
Agreement,  this  Agreement  shall not  otherwise be modified,  supplemented  or
altered in any  respect  except  with the  consent in writing of the  Registered
Holders of Warrant  Certificates  representing  not less than a majority  of the
Warrants then outstanding.

           (b) The Company shall have the right to reduce the Exercise  Price on
not less than thirty days' prior written notice to the Registered Holders of the
Warrants.

           SECTION  17.  Notices.  All  notices,  requests,  consents  and other
communications  hereunder  shall be in writing  and shall be deemed to have been
made when delivered or mailed first class registered or certified mail,  postage
prepaid as follows: if to the Registered Holder of a Warrant Certificate, at the
address of such holder as shown on the registry books  maintained by the Warrant
Agent;  if to the  Company,  at 1675 West  Maple  Road,  Troy,  Michigan  48084,
Attention:  Corporate  Secretary;  if to the  Warrant  Agent,  at its  Corporate
Office.

           SECTION 18.   Governing Law.  This Agreement shall be governed by and
construed in accordance with the laws of the Commonwealth of Massachusetts, 
without reference to principles of conflict of laws.

           SECTION 19. Binding Effect.  This Agreement shall be binding upon and
inure to the benefit of the Company and the Warrant Agent (and their  respective
successors   and  assigns)  and  the  holders  from  time  to  time  of  Warrant
Certificates.  Nothing in this  Agreement  is intended or shall be  construed to
confer upon any other person any right, remedy or claim, in equity or at law, or
to impose upon any other person any duty, liability or obligation.

           SECTION 20.   Termination.  This Agreement shall terminate on the
earliest to occur of (i) the Expiration Date of all the Warrants, (ii) the date
upon which all Warrants have been exercised and (iii) the date on which the
Company certifies to the


                                  13


<PAGE>



Warrant  Agent  that  no  Warrants  are  outstanding;   provided  however,  that
notwithstanding  any such  termination,  the Warrant Agent shall be obligated to
deliver funds to the Company in accordance with this Agreement.

           SECTION 21.   Counterparts.  This Agreement may be executed in all
counterparts, all of which taken together shall constitute a single document.

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

           THIS  CERTIFIES   THAT:   ______________________________________   or
registered  assigns is the registered  holder (the  "Registered  Holder") of the
number  of  Warrants  set forth  above,  each of which  represents  the right to
purchase one fully paid and nonassessable  share of common stock, par value $.01
per share (the "Common Stock"), of Energy Conversion  Devices,  Inc., a Delaware
corporation (the  "Company"),  at any time until the Expiration Date hereinafter
referred to, by surrendering  this Warrant  Certificate,  with the exercise form
set forth hereon duly executed with signatures  guaranteed as provided below, at
the office maintained pursuant to the Warrant Agreement  hereinafter referred to
for that purpose by State  Street Bank and Trust  Company,  or its  successor as
warrant agent (any such warrant agent being herein called the "Warrant  Agent"),
and by paying in full the sum of $_____  per share,  on or prior to January  31,
2000 and $____ per share after January 31, 2000 and on or prior to July 31, 2001
(the "Exercise  Price"), plus transfer taxes,  if any.  Payment of the Exercise
Price shall be made in United States currency, by certified check or money order
payable to the order of the Company.

           Upon certain events provided for in the Warrant Agreement hereinafter
referred  to,  the  Exercise  Price and the  number  of  shares of Common  Stock
issuable upon the exercise of each Warrant are required to be adjusted.

           No Warrant may be exercised  after 5:00 P.M.  (New York City time) on
the expiration date (the  "Expiration  Date") which will be July 31, 2001. After
the Expiration Date, all Warrants evidenced hereby shall thereafter become void,
and the holders thereof shall have no rights thereunder.

           Prior to the Expiration  Date,  subject to any applicable laws, rules
or  regulations   restricting   transferability   and  to  any   restriction  on
transferability  that may appear on this Warrant  Certificate in accordance with
the terms of the  Warrant  Agreement  hereinafter  referred  to, the  Registered
Holder shall be entitled to transfer this Warrant Certificate in whole


                                   1


<PAGE>



or in part upon  surrender  of this  Warrant  Certificate  at the  office of the
Warrant Agent  maintained for that purpose with the form of assignment set forth
hereon duly executed,  with signatures guaranteed by a member firm of a national
securities  exchange,  a  commercial  bank, a savings bank or a savings and loan
association  or a trust company  located in the United  States,  a member of the
National  Association of Securities  Dealers,  Inc. or other eligible  guarantor
institution  which is a participant  in a signature  guarantee  program (as such
terms are defined in Reg. 240.17Ad-15 under the Securities Exchange Act of 1934)
applicable  to  the  Warrant  Agent.  Upon  any  such  transfer,  a new  Warrant
Certificate or Warrant  Certificates  representing  the same aggregate number of
Warrants  will be  issued in  accordance  with the  instructions  in the form of
assignment.

           Upon the exercise of less than all of the Warrants  evidenced by this
Warrant  Certificate,  there  shall be  issued  to the  Registered  Holder a new
Warrant Certificate in respect of the Warrants not exercised.

           Prior to the Expiration Date, the Registered Holder shall be entitled
to  exchange   this  Warrant   Certificate,   with  or  without   other  Warrant
Certificates, for another Warrant
Certificate or Warrant  Certificates  for the same aggregate number of Warrants,
upon  surrender of this Warrant  Certificate  at the office  maintained for such
purpose by the Warrant Agent.

           No fractional shares will be issued upon the exercise of Warrants. As
to any final  fraction of a share,  which the  Registered  Holder of one or more
Warrant  Certificates,  the  rights  under  which  are  exercised  in  the  same
transaction,  would  otherwise be entitled to purchase upon such  exercise,  the
Company shall pay the cash value  thereof  determined as provided in the Warrant
Agreement.

           This Warrant  Certificate  is issued under and in  accordance  with a
Warrant  Agreement  between  the Company  and the  Warrant  Agent (the  "Warrant
Agreement") and is subject to the terms and provisions contained in said Warrant
Agreement,  to all of which terms and provisions the Registered  Holder consents
by acceptance hereof.

           This Warrant  Certificate  shall not entitle the Registered Holder to
any  of  the  rights  of  a  stockholder  of  the  Company,  including,  without
limitation, the right to vote, to receive dividends and other distributions,  or
to  attend or  receive  any  notice of  meetings  of  stockholders  or any other
proceedings of the Company.

           This Warrant  Certificate shall not be valid for any purpose until it
shall have been countersigned by the Warrant Agent.

                To Be Executed by the Registered Holder
                     in Order to Exercise Warrants
