hybrid electric vehicles.  Management believes that funds generated from
operations; new business agreements; equity financing, including the exercise
of Common Stock purchase warrants and exercise of stock options; debt
financing; new government contracts and the cost-containment initiatives (see
Note B of Notes to Consolidated Financial Statements), together with existing
cash and cash equivalents, will be adequate to support the Company's
operations for the coming year.  However, the amount and timing of such
activities are uncertain.  Accordingly, no assurances can be given as to the
timing or success of the aforementioned plans, negotiations, discussions and
programs.

      These factors, among others, raise substantial doubt about the
Company's ability to continue as a going concern in the absence of sufficient
additional funds and the sustained achievement of profitable operations.  The
accompanying consolidated financial statements do not include any adjustments
relating to the recoverability and classification of assets carrying amounts
or the amount and classification of liabilities that might be necessary
should the Company be unable to continue as a going concern (see Note B of
Notes to Consolidated Financial Statements).

Nature of Business
------------------

      Energy Conversion Devices, Inc. (ECD) is a technology, product
development and manufacturing company engaged in the invention, engineering,
development and commercialization of new materials, products and production
technology in the fields of alternative energy technology and information
technology.

Financial Statement Presentation, Principles of Consolidation and
-----------------------------------------------------------------
Equity Accounting
-----------------

      The consolidated financial statements include the accounts of ECD and
its 100%-owned manufacturing and sales subsidiaries United Solar Ovonic Corp.
and United Solar Ovonic LLC (jointly referred to as "United Solar Ovonic")
and its approximately 91%-owned subsidiary Ovonic Battery Company, Inc.
(Ovonic Battery) and, as of December 2, 2004, Ovonic Hydrogen Systems
(collectively the "Company").  No minority interest related to Ovonic Battery
is recorded in the consolidated financial statements because there is no
additional funding requirement by the minority shareholders.  The Company has

number of strategic alliances and has four major investments accounted for
using the equity method: (i) Cobasys LLC (formerly known as Texaco Ovonic
Battery Systems LLC), a joint venture between Ovonic Battery and
ChevronTexaco Technology Ventures LLC (CTTV), a unit of ChevronTexaco
Corporation, each having 50% interest in the joint venture; (ii) Ovonic
Hydrogen Systems LLC (Ovonic Hydrogen) (formerly known as Texaco Ovonic
Hydrogen Systems LLC), a joint venture between ECD and CTTV, each having 50%
interest in the joint venture through December 2, 2004 and 100% owned by ECD
thereafter; (iii) Ovonyx, Inc., a 41.7%-owned joint venture with Mr. Tyler
Lowrey, Intel Capital and other investors; and (iv) Ovonic Media, LLC, a
joint venture owned 51% by General Electric through its GE Plastics business
unit and 49% by ECD.  See Note E of Notes to Consolidated Financial
Statements for discussions of all of the Company's ventures.

      At December 31, 2004 and at June 30, 2004, the Company's investments in
Cobasys, Ovonyx and Ovonic Media are recorded at zero.  In December 2004, the
Company made a $100,000 investment in Ovonyx.  The Company will continue to
carry its investment in each of these joint ventures at zero until the
venture becomes profitable (based upon the venture's history of sustainable
profits), at which time the Company will start to recognize over a period of
years its share, if any, of the then equity of each of the ventures, and will
recognize its share of each venture's profits or losses on the equity method
of accounting.  To the extent that the Company has made cash or other
contributions, it recognizes its proportionate share of any losses until the
investment reaches zero.

      Intellectual property, including patents, resulting from the Company's
investments in its technologies, is valued at zero in the balance sheet.
Intellectual property provides the foundation for the creation of the
important strategic alliances whereby the Company provides intellectual
property and patents and joint venture partners provide cash.

      While the Company believes, based upon the opinion of legal counsel,
that it has no obligation to fund any losses that its joint ventures incur
beyond the Company's investment, the Company has decided to fund certain of
its joint ventures (see Note E of Notes to Consolidated Financial
Statements).

      Upon consolidation, all intercompany accounts and transactions are
eliminated.  Any profits on intercompany transactions are eliminated to the
extent of the Company's ownership percentage.

Use of Estimates
----------------

      The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America (U.S. GAAP)
requires management to make estimates and assumptions that affect amounts
reported therein.  Due to the inherent uncertainty involved in making
estimates, actual results reported in future periods may be based upon
amounts that differ from those estimates.

Reclassifications
-----------------

      Certain prior year amounts have been reclassified to conform with 2004
presentation.

Overhead and General and Administrative Allocations
---------------------------------------------------

      The Company allocates overhead and general and administrative expenses
to product development research expenses and to cost of revenues from
research and development agreements based on a percentage of direct labor
costs.  For cost of revenues from product development agreements, this
allocation is limited to the amount of revenues, after direct expenses, under
the applicable agreements.  Overhead is allocated to cost of product sales
through the application of overhead to inventory costs.

      The following is a summary of the gross selling, general and
administrative expenses and the aforementioned allocations:

Distribution from Joint Venture
-------------------------------

      In July 2004, Cobasys made an $8,000,000 special distribution to each
of Ovonic Battery and CTTV for partial reimbursement of legal expenses paid
on behalf of Cobasys for litigation with Matsushita Electric Industrial Co.
Ltd. (MEI) and related companies (see Note B of Notes to Consolidated
Financial Statements).

Stock-Based Compensation
------------------------

      ECD applies APB 25 to its stock-based compensation awards to employees.  
Had compensation costs for ECD's stock option plans been determined based upon 
the fair value at the grant date for awards under these plans consistent with
the methodology prescribed under SFAS 123, the Company's net income (loss) and 
net income (loss) per share for the three months and six months ended 
December 31, 2004 and 2003 would have changed as follows:

Basic and Diluted Net Income (Loss) Per Share
---------------------------------------------

      Basic net income (loss) per common share is computed by dividing the
net income (loss) by the weighted average number of common shares
outstanding.  ECD uses the treasury stock method to calculate diluted
earnings per share.  Potential dilution exists from stock options and
warrants.  Weighted average number of shares outstanding and basic and
diluted net income (loss) per share for the three months and six months ended
December 31 are computed as follows:


  
                                                          Three Months Ended            Six Months Ended

      Due to the Company's net loss in 2003, weighted average shares of
potentially dilutive securities of 5,210 and 5,343 for the three and six
months ending December 31, 2003, respectively, were excluded from the
calculations of diluted net loss per share, as inclusion of these securities
would have been antidilutive to the net loss per share.

      Additional securities of 397,786 and 3,139,657 for the three months
ended December 31, 2004 and 2003, respectively, and 947,367 and 2,507,183 for
the six months ended December 31, 2004 and 2003, respectively, were excluded
from the 2004 and 2003 calculations of weighted average shares of potentially
dilutive securities.  Because of the relationship between the exercise prices
and the average market price of ECD's Common Stock during these periods,
these securities would have been antidilutive regardless of the Company's net
income or loss.

Recent Pronouncements
---------------------

      In November 2004, the Financial Accounting Standards Board (FASB)
issued Statement of Financial Accounting Standards (SFAS) No. 151, "Inventory
Costs."  This Statement clarifies the accounting for abnormal amounts of idle
facility expenses, freight, handling costs and wasted material spoilage and
is effective for fiscal years beginning after June 15, 2005.  The Company is
in the process of reviewing this Statement for the future effect on the
Company's consolidated financial position or results of operations.

      In December 2004, the FASB issued SFAS No. 153, "Exchanges of
Nonmonetary Assets."  This Statement addresses the measurement of exchanges
of nonmonetary assets and is effective for nonmonetary asset exchanges
occurring in fiscal years beginning after June 15, 2005.  The Company does
not believe that this will have an effect on the Company's consolidated
financial position or results of operations.

      In December 2004, the FASB issued SFAS No. 123(R), "Share-Based
Payment."  This Statement requires a public entity to measure the cost of
employee services received in exchange for an award of equity instruments
based on the grant-date fair value of the award and is effective as of the
beginning of the first interim or annual reporting period that begins after
June 15, 2005.  The Company is in the process of reviewing this Statement for
the future effect on the Company's consolidated financial position or results
of operations.

Restructuring
-------------

      On August 12, 2004, the Board of Directors approved management's
business restructuring plan to take full advantage of the battery settlement
agreement announced on July 7, 2004 and the increasing market interest in
solar energy systems and hybrid electric vehicles.  Our strategy is to
transition from a research-oriented company to the next phase of development,
which is to commercialize the products we have developed and

-------------------------------

concentrate on growing sales revenues and equity value in our core commercial
businesses with the goal of moving the Company into a position of having
sustained profitability by July 2006.

      The restructuring will increase product revenues while enabling us to
carry out major cost-reduction measures, including significant reductions in
the workforce to right size activities to support our core commercial
businesses.  We will manage a reduced portfolio of advanced product
development activities and a leaner R&D team to grow future businesses.

      The core commercial businesses on which the Company is focusing are
United Solar Ovonic, Cobasys and Ovonyx.

      On December 2, 2004, as part of its focus on its core businesses, ECD
entered into a series of agreements with CTTV and Cobasys to expand the scope
of licenses granted to Cobasys at the time of the formation of the joint
venture in July 2001.

      In consideration of the expanded license, revised joint venture
agreements and the grant to CTTV of a security interest in our membership 
interest in Cobasys, ECD, through its subsidiary Ovonic Battery, received an 
option to purchase the 4,376,633 shares of ECD Common Stock currently owned by 
a subsidiary of ChevronTexaco.  The option is exercisable at $4.55 per share 
and expires on November 1, 2005.

      The amount of the license fee was calculated based upon the application
of the Black Scholes valuation model to the difference between the closing
price of ECD Common Stock on December 2, 2004 on the NASDAQ National Market
and the $4.55 per share option price under the option granted by a subsidiary
of ChevronTexaco Corporation to ECD's Ovonic Battery subsidiary on December 2, 
2004 to acquire 4,376,633 shares of ECD Common Stock.

      The transaction increased ECD's revenues and decreased additional
paid-in capital in the quarter ended December 31, 2004 by $79,532,000 as a
result of this one-time, non-cash event.

      The 4,376,633 shares of ECD Common Stock subject to the option
represent approximately 17% of the currently issued and outstanding shares.
ECD believes that the option arrangement will provide it with value and added
flexibility in its activities to secure additional capital required for its
future growth.

      The agreement also provides a mechanism for additional funding from
CTTV to continue Cobasys' expansion.  CTTV will be entitled to a priority
right of repayment for providing the additional funding.  ECD and CTTV will
each continue to own a 50 percent interest in Cobasys, subject to adjustment
under certain circumstances.

      In addition, CTTV transferred to ECD its interest in Ovonic Hydrogen in
consideration of relieving CTTV of any continuing obligations to fund Ovonic
Hydrogen.  ECD received $4,675,000 from CTTV for payment of restructuring fees. 
The $4,675,000 received from CTTV was $2,266,000 (net of tax) in excess of 
restructuring costs through December 31, 2004.  The Company has recognized this 
as an extraordinary item (gain) in the three months and six months ended 
December 31, 2004.

      The hydrogen business unit was renamed Ovonic Hydrogen Systems LLC and
ECD will fund Ovonic Hydrogen on a reduced level.  It will focus on
continuing to commercialize small portable metal hydride storage systems that
have current and near-term market applications while continuing to develop
and commercialize ECD's proprietary reversible solid metal hydride-based
low-pressure hydrogen storage systems for longer-term stationary,
transportation and infrastructure applications.

Settlement Agreement
--------------------

      In July 2004, ECD and Cobasys entered into a settlement agreement with
MEI, Panasonic EV Energy Co., Ltd. (PEVE), and Toyota Motor Corporation with
respect to patent infringement disputes and counterclaims involving nickel
metal hydride (NiMH) batteries before the International Chamber of Commerce,
International Court of Arbitration. Under the terms of the settlement, no
party admitted any liability.

      As part of the settlement, ECD and its subsidiary, Ovonic Battery,
received a $10 million license fee from MEI and PEVE.  This fee was recorded
as a deferred patent license fee in July 2004 and is being amortized to
income over 10.5 years.  The Company recognized $238,095 and $476,190 as
revenues from license and other agreements in the three months and six months
ended December 31, 2004, respectively, in connection with the amortization of
this fee.  In addition, Cobasys received a $20 million license fee from MEI,
PEVE and Toyota, of which $4 million was placed in escrow for a
next-generation NiMH battery development project plan.  Upon receipt of the
license fee, Cobasys made an $8 million distribution each to Ovonic Battery
and CTTV representing a partial reimbursement of legal expenses in the six
months ended December 31, 2004.  The Company recorded this $8 million as a
distribution from joint venture in the six months ended December 31, 2004.

Joint Ventures
--------------

Cobasys

      In July 2001, Ovonic Battery and CTTV, a unit of ChevronTexaco, formed
a strategic alliance (Cobasys LLC).  ChevronTexaco has agreed to invest up to
$160,000,000 ($157,000,000 of which has been received as of December 31,
2004) to match the Company's technological contribution in the venture.
Cobasys is owned 50% by Ovonic Battery and 50% by CTTV.

      On December 2, 2004, as part of its focus on its core businesses, ECD
entered into a series of agreements with CTTV and Cobasys to expand the scope
of licenses granted to Cobasys at the time of the formation of the joint
venture in July 2001 (see Note B of Notes to Consolidated Financial
Statements).

      In July 2004, ECD and Cobasys entered into a settlement agreement with
MEI, Panasonic EV Energy Co., Ltd. (PEVE), and Toyota Motor Corporation with
respect to patent infringement disputes and counterclaims involving nickel
metal hydride (NiMH) batteries before the International Chamber of Commerce,
International Court of Arbitration. Under the terms of the settlement, no
party admitted any liability.

      The Company recorded revenues from Cobasys of $592,000 and $1,067,000
for the three months and six months ended December 31, 2004, respectively,
and $1,935,000 and $3,351,000 for the three months and six months ended
December 31, 2003, respectively, for services performed on behalf of Cobasys
(primarily for advanced product development and market development work).
The Company recorded revenues of zero and $34,000 for the three months and
six months ended December 31, 2004 and revenues of zero and $2,000 for the
three months and six months ended December 31, 2003, respectively, for
products sold to Cobasys.

      The Company also recorded revenues from Cobasys of zero and $45,000 for
the three months and six months ended December 31, 2004, respectively, and
$45,000 and $90,000 for the three months and six months ended December 31,
2003, respectively, for rent of a portion of one of the Company's facilities.

      The following sets forth certain financial data regarding Cobasys that
are derived from its financial statements:

Ovonyx

      ECD owns 41.7% of Ovonyx, Mr. Tyler Lowrey and his colleague own 41.7%
of Ovonyx, and Intel and other investors own the remainder.  On a fully
diluted basis after giving effect to the exercise of stock options and
warrants, our ownership of Ovonyx would be 31.4%.  ECD has contributed
intellectual property and licenses for its interest in Ovonyx.

---------------------------------------------------

      In October 2002, ECD, through a newly formed company, Ovonic Cognitive
Computer, Inc., which is owned 95% by ECD and 5% by Ovonyx, made a capital
contribution of $1,000,000 in Ovonyx in exchange for technology previously
contributed by ECD to Ovonyx and an exclusive, royalty-bearing license, which
requires annual minimum royalty payments in order to maintain its
exclusivity.  ECD made a $50,000 minimum royalty payment in November 2003 and
a $100,000 payment in December 2004.  ECD recorded its $1,150,000 investment
in Ovonyx and accounts for this investment on the equity method and is
recognizing its proportionate share of Ovonyx losses to the extent of its
$1,150,000 investment.  In each of the three months and six months ended
December 31, 2004, ECD recorded an equity loss of $100,000; and in the three
months and six months ended December 31, 2003, ECD recorded an equity loss of
$304,000 and $548,000, respectively, related to its investment in Ovonyx.

      ECD recorded revenues from Ovonyx of $62,000 and $125,000,
respectively, for the three months and six months ended December 31, 2004 and
$34,000 and $71,000, respectively, for the three months and six months ended
December 31, 2003, representing services provided to this joint venture.

Ovonic Media

      In 2000, we and General Electric, through its GE Plastics business
unit, formed a joint venture, Ovonic Media, LLC, to design, develop,
demonstrate and commercialize our proprietary continuous web roll-to-roll
technology for the ultra-high-speed manufacture of optical media products,
primarily rewritable DVDs.  We have contributed intellectual property,
know-how, licenses and equipment to the joint venture.  GE has made cash and
other contributions to the joint venture.  Since its inception, Ovonic Media
has paid us $5.6 million through the end of fiscal year 2003 for services to
the joint venture.

      GE informed ECD that additional funding after January 3, 2003 was
suspended.   ECD is considering how to best position the joint venture in
order to meet the needs of the marketplace, and secure new equity investors
and strategic partners to fund the joint venture's operations.  As the next
business step, we are seeking to secure a partner that is a leader in the
storage media industry to facilitate the commercialization and funding of our
technology.  In the interim, ECD is directly funding continued product
development activities for this technology at a reduced level.

Investments in Rare Earth Ovonic

      During the year ended June 30, 2000, ECD and Ovonic Battery signed
agreements with Rare Earth High-Tech of Inner Mongolia, China.  The agreements
called for the creation of three joint ventures for manufacturing and
licensing of advanced NiMH battery technology, alloy powders, and production
equipment, all for certain battery applications for NiMH batteries.  ECD and
Ovonic Battery initially contributed technology for their 19% interest in
each of these joint ventures.  In February 2002, ECD and Ovonic Battery
jointly

made a proportionate $1,710,000 cash investment in the Rare Earth Ovonic
joint ventures and maintained their 19% interest in these entities.  All of
these joint ventures are being accounted for using the cost method of
accounting.

      At December 31, 2004, the Company reviewed its revenues and cost
estimates for its Rare Earth Ovonic joint ventures in connection with its
investment ($1,710,000) in Rare Earth Ovonic.  Based upon these estimates,
the Company took an impairment charge of $1,710,000 as of December 31, 2004.

      Ovonic Battery has three contracts totaling $63,600,000 for supplying
equipment and technology to its Rare Earth Ovonic joint ventures in China.
As of December 31, 2004, Ovonic Battery has received payments totaling
$59,484,000 under the three contracts.  In December 2004, the Company
reviewed its estimates to complete the equipment under the Rare Earth Ovonic
contracts.  As a result of this review and the changes in estimates, the
Company reduced its estimated margin from 12% to 8%.  This resulted in a
reduction in the cumulative revenue for these contracts at December 31, 2004
of approximately $2,668,000.

NOTE F - Liabilities
--------------------

Warranty Liability
------------------

      The Company estimates the liability for product warranty costs based
upon its past experience and best estimate of future warranty claims.  The
following is a summary of the changes in the product warranty liability
during the six months ended December 31, 2004 and 2003:

                                                       Six Months Ended

                                                 ===========    ===========  

      Warranty liability is recorded at the time that the product is sold
(for sales of photovoltaic products) or at the time that revenue is
recognized (for machine-building and equipment sales).

Government Contract Reserve
---------------------------

      The Company's contracts with the U.S. Government and its agencies are
subject to audits by the Defense Contract Audit Agency (DCAA).  DCAA has
audited the Company's indirect rates, including its methodology of computing
these rates, for the years ended June 30, 1994 through June 30, 2003 for
United Solar Ovonic and the years ended June 30, 2000 through June 30, 2002
for ECD.  In its reports, DCAA has questioned the allowability of and the
allocability of certain costs as well as the Company's methodology for
allocating independent research and development to its indirect cost pools.
In addition, DCAA has stated that there could be penalties imposed.  The
Company is in the process of discussing each of these items in detail with
DCAA.  Management believes that some of these DCAA assertions are without
merit.  The Company has recorded a reserve of $1,682,000 and $1,847,000 at
December 31, 2004 and June 30, 2004, respectively, related to these issues.

              Six months ended       $ 1,832,492      $  20,727

      Included in creditable royalties earned and recognized as revenues in
the three months and six months ended December 31, 2004 are $686,000 and
$1,811,000, respectively, related to advance royalty payments made by
licensees to the Company associated with license agreements under which the
licensees no longer have contractual obligations to make payments.

      There are no obligations in connection with any of the advance royalty
agreements which require the Company to incur any additional costs.

NOTE H - Product Sales, Royalties, Revenues from Product Development 
--------------------------------------------------------------------
Agreements and License and Other Agreements
-------------------------------------------

      The Company has product sales and business agreements with third
parties and with related parties for which royalties and revenues are
included in the consolidated statements of operations.  Product sales include
photovoltaic products, revenues related to machine-building and equipment
sales contracts, nickel hydroxide and metal hydride materials.  Revenues
related to machine-building and equipment sales contracts are recognized on
the percentage-of-completion method of accounting using the costs incurred to
date as a percentage of the total estimated costs.  All other product sales
are recognized when the product is shipped.  These products are shipped FOB
shipping point.  Currently, low sales volumes for metal hydride materials and
machine building combined with high fixed costs result in losses.

accompanying Quarterly Financial Information and Notes thereto and the
Company's Annual Report on Form 10-K for the year ended June 30, 2004 and is

    CAUTIONARY STATEMENT FOR PURPOSES OF THE "SAFE HARBOR" PROVISIONS OF 
            THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

      This Quarterly Report on Form 10-Q contains forward-looking statements
about our financial condition, results of operations, plans, objectives,
future performance and business.  In addition, from time to time we and our
representatives have made or may make forward-looking statements orally or in
writing.  The words "may," "will,"  "believes," "expects," "intends,"
"anticipates," "estimates," and similar expressions have been used in this
Quarterly Report to identify forward-looking statements.

      We have based these forward-looking statements on our current
expectations with respect to future events and occurrences.  Investors are
cautioned that our actual results in the future may differ materially from
the expected results reflected in our forward-looking statements.  The
expected results reflected in our forward-looking statements are subject to
various significant risks and uncertainties, including the following:

   (o)   we have a history of losses, our future profitability is uncertain,
         and our financial statements are subject to a going concern
         explanatory paragraph by our independent registered public
         accounting firm;

   (o)   we need to obtain debt or additional equity financing to continue 
         to operate our business and financing may be unavailable, reduce
         our stock price or be available only on disadvantageous terms;

   (o)   we have disclosed several material weaknesses in our internal
         controls that, if not remedied, could result in material
         misstatements in our financial statements, cause investors to lose
         confidence in our reported financial information, and have a
         negative effect on the trading price of our stock;

   (o)   our revenues are dependent upon licensing arrangements and joint
         ventures, and our licensees and joint venture partners may be
         unwilling or unable to devote their financial resources and
         manufacturing and marketing capabilities to commercialize
         products based on our technologies;

   (o)   we receive a significant portion of our revenues from a small number 
         of customers;

   (o)   we may be unable to continue to protect and maintain the proprietary
         nature of our technology, or to convince others of the
         necessity of licensing our technology without litigation;

   (o)   other companies may be successful in asserting patent infringement 
         or other claims against us which prevent us from commercializing
         products

                                     29




         based on our technology or which force us to make royalty or
         other payments to competitors;

   (o)   other companies may develop competing technologies which cause our
         technology to become obsolete or noncompetitive;

   (o)   our ability to succeed will be dependent upon our ability to
         successfully implement our business plan, as to which no
         assurance can be given;

   (o)   we may experience performance problems with key suppliers or
         subcontractors;

   (o)   adverse changes may occur in general economic conditions or in
         political or competitive forces affecting our business;

   (o)   competition may increase in our industry or markets;

   (o)   our government product development or research contracts may be
         terminated by unilateral government action, or we may be
         unsuccessful in obtaining new government contracts to replace
         those which have been terminated or completed;

   (o)   we may become subject to legal or regulatory proceedings which may
         reach unfavorable resolutions;

   (o)   there may be adverse changes in the securities markets which affect
         the price of our stock;

   (o)   we may suffer the loss of key personnel or may be unable to attract
         and retain qualified personnel to maintain and expand our business;

   (o)   our product development and commercialization programs involve a
         number of uncertainties and we may never generate sufficient revenues
         to become profitable;

   (o)   we may not achieve the designed output capabilities of certain
         manufacturing equipment designed and built by us;

   (o)   we rely on collaborative relationships and termination of any of these
         relationships and the underlying contracts could reduce the
         financial resources available to us, including future revenues;

   (o)   some of our key technologies have not been used to produce commercial
         products and may not be capable of producing such products;

   (o)   our commercialization programs will require substantial additional
         future funding which could hurt our operational and financial
         condition;

   (o)   future sales of our securities may depress the price of our
         securities; or

   (o)   our securities may not allow our holders to receive a return on
         such securities other than through the sale of the securities.

      There is also the risk that we incorrectly analyze these risks or that
strategies we develop to address them are unsuccessful.

      These forward-looking statements speak only as of the date of this
Quarterly Report. All subsequent written and oral forward-looking statements
attributable to us or any person acting on our behalf are qualified in their
entirety by the cautionary statements in this section.  Because of these
risks, uncertainties and assumptions, you should not place


                                      30



undue reliance on these forward-looking statements.  We are not obligated to
update or revise any forward-looking statement, whether as a result of new
information, future events or otherwise.

United Solar Ovonic Segment
---------------------------

      The United Solar Ovonic segment had a decreased operating loss in 2004
versus 2003 primarily due to significantly higher revenues and the impact of
cost reductions in 2004.

      United Solar Ovonic's 2004 revenues increased by $4,572,000 from
increased product sales.  Photovoltaic sales increased by 69% to $11,235,000
for 2004 from $6,634,000 for 2003.

      Gross loss on United Solar Ovonic's product sales was $220,000 in 2004
compared to a gross loss of $1,524,000 in 2003 because of higher sales and
lower material costs.

      United Solar Ovonic's revenues from product development agreements in
the three months ended December 31, 2004 were $2,255,000 compared to
$2,285,000 in 2003.

      The product development expenditures were used to fund the development
of new products for space and airship applications and to develop lower-cost
and higher-efficiency terrestrial products.

      United Solar Ovonic's operating, general and administrative expenses
(net of allocations) decreased by $142,000 in 2004 as a result of reductions
in 2004 in the number of employees, in other employee-related costs and in
warranty expense, partially offset by reduced allocations ($52,000) to cost of
product development in 2004.

Energy Conversion Devices Segment
---------------------------------

      The ECD segment had a decreased operating loss in 2004 versus 2003,
primarily due to an increase in the segment's revenues, an increase from
royalties and other revenues, and the impact of ECD's cost-containment
program.

      ECD's revenues from product development agreements decreased in the
three months ended December 31, 2004 to $3,012,000 from $3,552,000 in the
three months ended December 31, 2003 due to lower revenues from Ovonic
Hydrogen ($1,446,000 in 2004 versus $2,313,000 in 2003) partially offset by
new contracts with the National Institute of Standards and Technology (NIST)
($599,000 in 2004 versus $173,000 in 2003).

      Revenues from product development agreements for the ECD segment for
the three months ended December 31, 2004 funded 45% of this segment's cost of
product development.  Revenues from product development agreements decreased
by $540,000 and spending increased by $6,000, resulting in an increase of
$546,000 in net cost of product development.

      Product development programs include work on the Ovonic Cognitive
Computer technology - a unique approach to develop computing based on the
learning capability that mimics the functionality of the human brain to
combine memory and processing in a single sub-micron device.  ECD is also
developing a unique three-terminal Ovonic threshold/memory device technology
to have high-speed, high-current capabilities.  Additionally, ECD continued
the development of the Ovonic regenerative fuel cell, which is a
fundamentally new approach to fuel cell technology and, effective December 2,
2004, continued the development of Ovonic Hydrogen.

      Other revenues are primarily related to personnel, facilities and
miscellaneous administrative and laboratory services provided to some of the
Company's joint ventures.  Other revenues were $203,000 in the three months
ended December 31, 2004 compared with $140,000 in the three months ended
December 31, 2003.

      ECD's operating, general and administrative expenses (net of
allocations) were $1,533,000 in 2004 compared to $1,944,000 in 2003.  The
decrease in the net expense for 2004 was due to reductions in 2004 in the
cost of outside services and communications.

Ovonic Battery Segment
----------------------

      The Ovonic Battery segment had an operating income in 2004 versus an
operating loss in 2003 primarily resulting from a license agreement, and the
recognition of revenue of $79,532,000 in 2004 as described in Note B of Notes
to Consolidated Financial Statements.

      The increase in Ovonic Battery's revenues was primarily due to the
aforementioned license agreement, partially offset by reduced equipment sales
to Rare Earth Ovonic and a reduction in revenues from product development
agreements principally related to decreased activities under the advanced
product development agreement from Cobasys.

      Equipment sales revenues decreased to a negative $2,668,000 in 2004
from $159,000 in 2003, primarily due to the cumulative revenue adjustment of
$2,668,000 in connection with a review of its estimates to complete the
equipment on the Ovonic Battery contracts with Rare Earth Ovonic to provide
battery-manufacturing equipment and a reduction in the estimated margin from
12% to 8%.  Sales of nickel hydroxide were $254,000 in 2004 versus $480,000
in 2003 as sales to the primary customer were affected by a temporary plant
closure and an accumulation of inventory by the customer.  The loss on
product sales increased to $3,682,000 in 2004 from $445,000 in 2003 due to 
Ovonic Battery's reduction in revenues on the Rare Earth Ovonic 
contract.

                                      33




      Ovonic Battery's revenues from product development agreements in the
three months ended December 31, 2004 decreased to $592,000 from $2,408,000 in
the three months ended December 31, 2003, primarily due to reduced activities
with Cobasys ($592,000 in 2004 compared to $1,935,000 in 2003) as Cobasys
moves into its commercialization phase.

      Revenues from product development agreements for the Ovonic Battery
segment in the three months ended December 31, 2004 funded 21% of Ovonic
Battery's cost of product development as Ovonic Battery significantly reduced
its spending on product development.  Revenues from product development
agreements decreased by $1,816,000 and spending decreased by $1,077,000,
resulting in an increase of $739,000 in net cost of product development.

      Royalties increased 31% to $782,000 in the three months ended December
31, 2004 from $596,000 in the three months ended December 31, 2003 due to
increased royalties earned on the sale of hybrid electric vehicle batteries
in 2004.

      Revenues from license and other agreements increased to $79,770,000 in
the three months ended December 31, 2004 from $25,000 in the three months
ended December 31, 2003.  The 2004 license fees result from the recognition
of revenue of $79,532,000 as a license fee (see Note B of Notes to Consolidated 
Financial Statements) and the amortization over 10.5 years of the $10,000,000 
payment received in the settlement of the patent infringement disputes and 
counterclaims in consideration of the licenses granted and the agreement to 
cross license through December 31, 2014 (see Note B of Notes to Consolidated 
Financial Statements).  The 2003 license fee resulted from a license to 
Linghao Battery of China.  Revenues from license and other agreements depend 
on a small number of new business arrangements, are sporadic and vary 
dramatically from period to period.

      Patent expenses were incurred in 2004 and 2003 in connection with the
protection of Ovonic Battery's United States and foreign patents covering its
proprietary technologies.  Total patent expenses decreased to $373,000 in the
three months ended December 31, 2004 from $3,536,000 in the three months
ended December 31, 2003, principally due to lower patent defense costs
($16,000 in 2004 versus $3,360,000 in 2003) for the protection of the
Company's NiMH battery patents and technology.

      Ovonic Battery's operating, general and administrative expenses (net of
allocations) decreased due to reductions in 2004 in the cost of outside
services and facilities.

      The $1,340,000 decrease in other income (net) ($1,669,000 loss in 2004
compared to $329,000 loss in 2003) resulted primarily from the impairment
loss ($1,710,000) in the Company's investment in Rare Earth Ovonic (see Note

reductions in 2004 in the number of employees, in other employee-related
costs and in warranty expense, partially offset by reduced allocations
($215,000) to cost of product development in 2004.

Energy Conversion Devices Segment
---------------------------------

      The ECD segment had a decreased operating loss in 2004 versus 2003,
primarily due to a decrease in the net cost of product development in 2004,
an increase in ECD segment's revenues due to an increase in royalty revenue,
and the impact of ECD's cost-containment program.

      ECD's revenues from product development agreements decreased in the six
months ended December 31, 2004 to $6,855,000 from $7,090,000 in the six
months ended December 31, 2003 due to lower revenues from Ovonic Hydrogen
($4,089,000 in 2004 versus $4,764,000 in 2003), partially offset by contracts
with NIST ($1,190,000 in 2004 versus $173,000 in 2003).

      Revenues from product development agreements for the ECD segment for
the six months ended December 31, 2004 funded 49% of this segment's cost of
product development.  Revenues from product development agreements decreased
by $235,000 and spending decreased by $911,000, resulting in a decrease of
$676,000 in net cost of product development.

      In the six months ended December 31, 2004, the Company reduced its
spending in Ovonic Media ($325,000), fuel cell ($895,000) and hydrogen
($386,000) compared to spending in the six months ended December 31, 2003.

      Product development programs include work on the Ovonic Cognitive
Computer technology - a unique approach to develop computing based on the
learning capability that mimics the functionality of the human brain to
combine memory and processing in a single sub-micron device.  ECD is also
developing a unique three-terminal Ovonic threshold/memory device technology
to have high-speed, high-current capabilities.  Additionally, ECD continued
the development of the Ovonic regenerative fuel cell, which is a
fundamentally new approach to fuel cell technology.

      Other revenues are primarily related to personnel, facilities and
miscellaneous administrative and laboratory services provided to some of the
Company's joint ventures.  Other revenues were $388,000 in the six months
ended December 31, 2004 compared with $306,000 in the six months ended
December 31, 2003.

      ECD's operating, general and administrative expenses (net of
allocations) were $2,422,000 in 2004 compared to $3,065,000 in 2003.  The
decrease in the net expense for 2004 was due to reductions in 2004 in the
cost of outside services and communications.

Ovonic Battery Segment
----------------------

      The Ovonic Battery segment had an operating income in 2004 versus an
operating loss in 2003, primarily from a license agreement and the
recognition of revenue of $79,532,000 in 2004.

      The increase in Ovonic Battery's revenues was primarily the recognition
of revenue of $79,532,000 from a license agreement in 2004, partially offset 
by a decrease in equipment sales to Rare Earth Ovonic and a reduction in 
revenues from product development agreements principally related to decreased 
activities under the advanced product development agreement from Cobasys.

      Equipment sales revenues decreased to negative $1,240,000 in 2004 from
$2,630,000 in 2003, primarily due to the cumulative revenue adjustment of
$2,668,000 in connection with a review of its estimates to complete the
equipment on the Ovonic Battery contracts with Rare Earth Ovonic to provide
battery-manufacturing equipment and a reduction in the estimated margin from
12% to 8% resulting in negative revenue of

                                      37




$1,598,000 in 2004 compared to revenue of $1,889,000 in 2003).  Sales of
nickel hydroxide were $254,000 in 2004 versus $715,000 in 2003 as sales to
the primary customer were affected by a temporary plant closure and an
accumulation of inventory by the customer.  The loss on product sales
increased to negative $4,011,000 in 2004 from negative $903,000 in 2003 due
to Ovonic Battery's reduction in revenues on the Rare Earth Ovonic contracts.

      Ovonic Battery's revenues from product development agreements in the
six months ended December 31, 2004 decreased to $1,067,000 from $4,246,000 in
the six months ended December 31, 2003, primarily due to reduced activities
with Cobasys ($1,067,000 in 2004 compared to $3,351,000 in 2003) as Cobasys
moves into its commercialization phase.

      Revenues from product development agreements for the Ovonic Battery
segment in the six months ended December 31, 2004 funded 20% of Ovonic
Battery's cost of product development as Ovonic Battery significantly reduced
its spending on product development.  Revenues from product development
agreements decreased by $3,179,000 and spending decreased by $2,741,000,
resulting in an increase of $438,000 in net cost of product development.

      Royalties increased 124% to $2,348,000 in the six months ended December
31, 2004 from $1,046,000 in the six months ended December 31, 2003 due to the
recognition of $1,125,000 related to an advance royalty payment made by a
licensee to the Company in 1993 associated with a license agreement under
which the licensee no longer has a contractual obligation to make payments
and increased royalties earned on the sale of hybrid electric vehicle
batteries in 2004.

      Revenues from license and other agreements increased to $80,008,000 in
the six months ended December 31, 2004 from $75,000 in the six months ended
December 31, 2003.  The 2004 license fees result from the recognition of
revenues of $79,532,000 as a license fee and the amortization over 10.5 years
of the $10,000,000 payment received in the settlement of the patent
infringement disputes and counterclaims in consideration of the licenses
granted and the agreement to cross license through December 31, 2014 (see
Note B of Notes to Consolidated Financial Statements).  The 2003 license fees
resulted from licenses to Linghao Battery and Mcnair-tech Co., Ltd. of China.  
Revenues from license and other agreements depend on a small number of new 
business arrangements, are sporadic and vary dramatically from period to period.


                                      38


      Patent expenses were incurred in 2004 and 2003 in connection with the
protection of Ovonic Battery's United States and foreign patents covering its
proprietary technologies.  Total patent expenses decreased to $812,000 in the
six months ended December 31, 2004 from $5,837,000 in the six months ended
December 31, 2003, principally due to lower patent defense costs ($189,000 in
2004 versus $5,471,000 in 2003) for the protection of the Company's NiMH
battery patents and technology.

      Ovonic Battery's operating, general and administrative expenses (net of
allocations) decreased due to reductions in 2004 in the cost of outside
services and facilities.

Other Income/Expense
--------------------

      The $6,376,000 improvement in other income (net) ($6,178,000 income in
2004 compared to $198,000 loss in 2003) resulted primarily from the
$8,000,000 distribution received from Cobasys as a distribution from the
joint venture associated with the settlement of the patent infringement
disputes and counterclaims (see Note B of Notes to Consolidated Financial
Statements), partially offset by the impairment loss ($1,710,000) in the
Company's investment in Rare Earth Ovonic (see Note E of Notes to
Consolidated Financial Statements).

                       Liquidity and Capital Resources

      As of December 31, 2004, the Company had consolidated cash, cash
equivalents, and accounts receivable (including $295,000 of amounts due from
related parties) of $42,251,000 and had consolidated working capital of
$37,247,000.

      As part of the settlement of the patent infringement disputes and
counterclaims, ECD and Ovonic Battery received a nonrefundable $10 million
patent license fee from MEI and PEVE.  In addition, Cobasys received a $20
million nonrefundable patent license fee from MEI, PEVE and Toyota, of which
$4 million was placed in escrow for a next-generation NiMH battery
development project plan.  Upon receipt of the funds, Cobasys made $8 million
distributions to each of Ovonic Battery and CTTV as a distribution from the
joint venture (see Note B of Notes to Consolidated Financial Statements).

      On August 12, 2004, the Board of Directors approved management's
business restructuring plan to take full advantage of the favorable battery
settlement agreement announced on July 7, 2004 and the increasing market
interest in solar energy systems and hybrid electric vehicles.  Our strategy
is to transition from a highly successful research-oriented company to the
next phase of development, which is to commercialize the products we have
developed and concentrate on growing sales revenues and equity value in our
core commercial businesses with the goal of moving the Company into a
position of having sustained profitability by July 2006.

      The restructuring is expected to increase product revenues while
enabling us to carry out major cost-reduction measures, including significant
reductions in the workforce to right size activities to support our core
commercial businesses.  We will manage a reduced portfolio of advanced
product development activities and a leaner R&D team to grow future
businesses.

                                      39



      The core commercial businesses on which the Company is focusing are our
wholly owned subsidiary, United Solar Ovonic, and our joint ventures, Cobasys
and Ovonyx.

      The December 2004 agreement with CTTV provides a mechanism for
additional funding from CTTV to continue the Cobasys expansion.  CTTV will be
entitled to priority right of repayment for providing the additional
funding.  ECD and CTTV will each continue to own a 50-percent interest in
Cobasys subject to adjustment under certain circumstances.

      The Company expects the amount of cash to be received under existing
product development agreements in the year ending June 30, 2005 to decrease
to approximately $16,882,000, compared to $36,678,000 received in the year
ended June 30, 2004, due to reduced funding to be received in the year ending
June 30, 2005 from ChevronTexaco.

      Our backlog of orders as of December 31, 2004 for machine-building and
equipment sales contracts, photovoltaic products and metal hydride materials
is $21,853,000 compared to a backlog of $9,166,000 at December 31, 2003.  The
increase in 2004 was due to an increase in the backlog for United Solar
Ovonic.  In fiscal 2006, we expect to recognize $3,679,000 of this backlog.

      As of December 31, 2004, the Company had $29,743,000 consolidated cash
and cash equivalents ($1,000,000 of which was restricted) consisting of money
market funds.  It is the Company's policy that investments (including cash
equivalents) shall be rated "A" or higher by Moody's or Standard and Poor's,
no single investment (excluding cash equivalents) shall represent more than
10% of the portfolio and at least 20% of the total portfolio shall have
maturities of 90 days or less.

      During the six months ended December 31, 2004, $5,437,000 of cash was
generated from operations.  The difference between the net income of
$68,485,000 and the net cash generated from operations was principally due to
the recognition of non-cash revenue of $79,532,000 as a license fee (see Note
B of Notes to Consolidated Financial Statements) and reductions in
nonrefundable advance royalties, partially offset by deferred nonrefundable
patent license fee received from the conclusion of the patent litigation with
MEI ($10,000,000), noncash costs (principally depreciation, $4,075,000),
changes in nonrefundable advance royalties ($1,832,000) and deferred revenues 
under business agreements ($894,000) (see Notes A, B and G of Notes to 
Consolidated Financial Statements).

      In consideration of the expanded license with Cobasys, revised joint
venture agreements and the collateralization of certain obligations, ECD
received an option to purchase the 4,376,633 shares of ECD Common Stock owned
by a subsidiary of ChevronTexaco. The option, exercisable at $4.55 per share
and expiring on November 1, 2005, will provide the Company with the added
flexibility to secure additional capital required for its future growth.

      The Company spent $730,000 on property, plant and equipment that was
placed in service during the six months ended December 31, 2004.  In total,
the Company expects to spend $2,000,000 for capital expenditures in fiscal
2005, primarily for manufacturing equipment at United Solar Ovonic and for
leasehold improvements to the Company's facilities.

                                      40



      As part of its long-standing strategy, the Company has made investments
in its technologies, which have resulted in enabling intellectual property
and products.  The technology emerging from these investments has enabled the
Company to finance its operations and growth through strategic alliances
(joint ventures and license agreements) with third parties who can provide
financial resources and marketing expertise for the Company's technologies
and products.

      The resultant strategic alliances and agreements with major companies
have accelerated the commercialization and development of the Company's
products and technologies.  While the Company's business partners have funded
most of its product development and commercialization activities, additional
sources of cash are required to sustain the Company's operations.  The
Company expects to continue to use significant cash to fund its operations in
the coming year and is engaged in a number of activities to raise capital,
grow revenues and reduce costs.

      Management believes that funds generated from operations; new business
agreements; equity financing, including the exercise of Common Stock purchase
warrants and exercise of stock options; debt financings; new government
contracts and the cost-containment initiatives, together with existing cash
and cash equivalents, will be adequate to support the Company's operations
for the coming year.  However, the amount and timing of such activities are
uncertain.  Accordingly, no assurances can be given as to the timing or
success of the aforementioned plans, negotiations, discussions and programs.
The report of the independent registered public accounting firm states that
"the Company's recurring losses from operations and need for additional
working capital raise substantial doubt about its ability to continue as a
going concern."  The Company has recurring losses from operations and is
actively engaged in discussions to obtain the needed additional working
capital.

Item 3.   Quantitative and Qualitative Disclosures about Market Risk
------    ----------------------------------------------------------

      The following discussion about our exposure to market risk of financial
instruments contains forward-looking statements.  Actual results may differ
materially from those described.

      Our holdings of financial instruments are comprised of debt securities
and time deposits.  All such instruments are classified as securities
available for sale.  We do not invest in portfolio equity securities, or
commodities, or use financial derivatives for trading purposes.  Our debt
security portfolio represents funds held temporarily, pending use in our
business and operations.  The Company had $29,738,000 and $13,074,000 of
these investments (including cash equivalents) on December 31, 2004 and June
30, 2004, respectively.  On December 31 and June 30, 2004, the investments
were all maturing on a daily basis.  It is the Company's policy that
investments (including cash equivalents) shall be rated "A" or higher by
Moody's or Standard and Poor's, no single investment (excluding cash
equivalents) shall represent more than 10% of the portfolio and at least 20%
of the total portfolio shall have maturities of 90 days or less.  Our market
risk primarily relates to the risks of changes in the credit quality of
issuers.  As of December 31, 2004, the risk associated with changes in
interest rates is minimal due to the short average maturity of the
investments.

Item 4.   Controls and Procedures
------    -----------------------

      In Item 9A, Controls and Procedures of the Company's Form 10-K for the
year ended June 30, 2004, the following four significant deficiencies were
identified pursuant to standards established by the Public Company Accounting
Oversight Board (PCAOB):

   1.    The Company has insufficient documentation of its policies and
         procedures around internal controls to ensure that the execution of
         activities and controls are consistent with management's objectives.

   2.    The Company does not currently have monitoring controls in place to
         determine whether controls that have been implemented by management,
         specifically in the financial reporting function, are actually
         operating consistently with management's objectives.

   3.    The Company has areas where employees are performing processes or
         controls that are incompatible with their functions. Segregation of
         duties issues were identified in the Accounts Receivable, Accounts
         Payable, Financial Reporting, Payroll, and Treasury functions.
   
   4.    The Company has certain weaknesses in the security of data within the
         Company's information systems. These include issues regarding security
         event logs and activity reports, assignment of administrator rights,
         segregation of duties, and access to data and applications.

      The Company's independent registered public accounting firm, Grant
Thornton LLP, has indicated that each of the above significant deficiencies
constitutes a material weakness in our internal controls pursuant to
standards established by the PCAOB.


                                      42



      As part of the Company's effort to ensure compliance with provisions of
Sarbanes-Oxley Section 404, the Company has devised a plan and committed the
required resources to address and remediate these material weaknesses prior
to our attestation of control effectiveness as of June 30, 2005.  This has
included the recent retention of a registered public accounting firm to
assist in the project direction, execution and external reporting.

      As of the end of the period covered by this report, an evaluation was
carried out under the supervision and with the participation of the Company's
management, including our Chief Executive Officer and Chief Financial
Officer, of the effectiveness of the design and operation of our disclosure
controls and procedures (as defined in Rules 13a-14(c) under the Securities
Exchange Act of 1934). Based upon that evaluation, which considered the
material weaknesses mentioned above, the Chief Executive Officer and Chief
Financial Officer concluded that the operation of these disclosure controls
and procedures were effective for gathering, analyzing and disclosing
information required to be disclosed in connection with the Company's filing
of its Quarterly Report on Form 10-Q for the quarter ended December 31, 2004.
No significant changes were made in our internal controls or in other factors
that could significantly affect these controls subsequent to the date of their 
evaluation.
