ITEM  3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

         GE paid an aggregate purchase price of $20,553,750 from its working
capital.


ITEM  4. PURPOSE OF TRANSACTION

         On September 28, 1999, General Electric Company ("GE") entered into a
Stock Purchase Agreement with Advanced Lighting Technologies, Inc. ("ADLT")
pursuant to which GE agreed to make an investment of $20,553,750 in ADLT. GE's
investment includes 761,250 shares of ADLT's newly-created Series A Convertible
Preferred Stock (the "Series A Preferred Stock") convertible at any time into
3,045,000 shares of ADLT Common Stock (subject to adjustment). GE also received
a Warrant (the "Initial Warrant") to purchase an additional 1,000,000 shares of
Common Stock of ADLT at $0.01 per share, which is immediately exercisable. The
Series A Preferred Stock, Common Stock issuable on exercise of the Initial
Warrant and the Common Stock held by GE at the time of the investment in ADLT
represent (after giving effect to the shares issued on exercise of the Initial
Warrant) approximately 18.8% of the voting power and equity ownership of ADLT.

         The Series A Preferred Stock has a liquidation preference of $27 per
share, plus an amount equal to 8% per annum from the date of issuance to the
date of payment ("Liquidation Preference Amount"). Upon liquidation, each share
of Series A Preferred Stock will be entitled to be paid the Liquidation
Preference Amount prior to any payment or distribution to the holders of ADLT
Common Stock. Following such payment, holders of Series A Preferred Stock will
be entitled to a proportional share of any distribution to holders of ADLT
Common Stock based on the number of shares of Common Stock into which the Series
A Preferred Stock could have been converted at the time of the liquidation.

         Each outstanding share of Series A Preferred Stock is convertible at
any time into four shares (subject to adjustment as described below) of Common
Stock of ADLT. Prior to conversion, holders of Series A Preferred Stock will be
entitled to vote in all shareholder matters together with the holders of ADLT
Common Stock as a single class. In any such vote, the holders of Series A
Preferred Stock will be entitled to four votes (equal to the number of shares of
Common Stock into which the Series A Preferred Stock held may initially be
converted). ADLT is required to redeem any shares of Series A Preferred Stock
which have not been converted or retired on September 30, 2010. Any such
redemption would be made at the Liquidation Preference Amount.

         Holders of the Series A Preferred Stock may require ADLT to redeem
their shares of Series A Preferred Stock by giving notice to ADLT on or before
September 30, 2004. If such notice is given, ADLT will be required make such
redemption on or prior to September 30, 2005. In addition, holders of Series A
Preferred Stock will be entitled to require ADLT to redeem the Series A
Preferred Stock following the occurrence of any of the following events (each a
"Triggering Event"): (1) failure of the shareholders of ADLT to approve, at the
1999 annual meeting, proposals necessary for exercise of any rights to acquire
beneficial ownership of additional shares of Common Stock; (2) failure of ADLT
and GE to obtain any approval required under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 ("HSR Act") in connection with GE's exercise of any
rights to acquire beneficial ownership of additional shares of Common Stock; or
(3) any action by ADLT to give effect to certain major corporate actions,
including actions to merge, sell all or a substantial portion of its assets
(other than in the ordinary course of business), issue capital stock, incur or
have outstanding indebtedness for borrowed money in excess of $210,000,000. Upon
the occurrence of a Triggering Event, the holders of the Series A Preferred
Stock may require ADLT to redeem their shares of Series A Preferred Stock by
giving notice to ADLT within 90 days following the Triggering Event. If such
notice is given, ADLT is required to make such redemption within one year
following such notice. Any such redemption would be made at the Liquidation
Preference Amount.

<PAGE>

CUSIP NO. 00753C 10 2                 13D


         Subject to approval by ADLT's shareholders, if ADLT fails to make any
redemption as required (subject to permitted deferrals in the event that such
redemption would cause an event of default with respect to certain indebtedness
of ADLT), the conversion ratio of the Series A Preferred Stock will be increased
from four shares of Common Stock to eight shares of Common Stock per share of
Series A Preferred Stock. In addition, also subject to the approval of ADLT's
shareholders, the conversion ratio will be subject to adjustment to prevent
dilution of the interest of GE by the issuance of Common Stock after the closing
of the GE transaction. Except for issuance of shares under existing employee
benefit plans, and certain other enumerated exceptions, any shares of Common
Stock issued at a price below $6.75 per share, or, if higher, below the then
current market price, would result in adjustment of the conversion ratio. Any
adjustment in the conversion ratio would not affect the voting power represented
by shares of Series A Stock prior to conversion.

         Under the terms of the Stock Purchase Agreement, GE was also granted
the Initial Warrant. The Initial Warrant entitles the holder to purchase shares
of ADLT Common Stock at $.01 per share. The Initial Warrant is immediately
exercisable for 1,000,000 shares (subject to adjustment) of ADLT Common Stock.
The number of shares subject to the Initial Warrant will be subject to
adjustment, after approval by ADLT shareholders, at any time prior to exercise
if the ADLT issues Common Stock at a price below $6.75 per share or, if higher,
below the then current market price.

         On the date of closing of the transactions contemplated by the Stock
Purchase Agreement, GE and ADLT entered into a Contingent Warrant Agreement
("Contingent Warrant Agreement"). The Contingent Warrant Agreement identifies
certain occurrences that entitle GE to make additional investments in ADLT and
receive the right to vote additional shares of ADLT Common Stock. The exercise
of certain of these rights is subject to applicable law, including the Ohio
Control Share Acquisition Act and the HSR Act.

         Upon the Second Occurrence (defined below) under the Contingent Warrant
Agreement, if it occurs, GE (i) is required to exercise in full the Initial
Warrant, (ii) is granted an option, at the then current market price, to
purchase from Wayne R. Hellman and Alan J. Ruud, the number of shares of Common
Stock which, together with the shares owned by GE, that would represent 25% of
the voting power of the ADLT (the "Option Shares"), (iii) is granted proxies
from Messrs. Hellman and Ruud with respect to the Option Shares, (iv) is granted
proxies from Mr. Hellman and Hellman, LTD. to vote the number of ADLT shares
then owned or controlled (including shares over which Mr. Hellman then has
voting power pursuant to the Hellman Voting Trust or Irrevocable Proxies granted
with respect to shares removed from the Hellman Voting Trust) by Mr. Hellman
(other than the Option Shares) and Hellman, LTD. and (v) is granted an
additional warrant (the "First Contingent Warrant") to purchase shares of ADLT
Common Stock at the then current market price. The number of shares subject to
the First Contingent Warrant would be equal to the number of shares required to
allow GE to have a majority of the voting power of ADLT, assuming GE had
effective proxies with respect to all shares as to which Messrs. Hellman and
Ruud then have voting power. The exercise of the First Contingent Warrant, the
options on shares held by Messrs. Hellman and Ruud, and effectiveness of GE's
proxy with respect to any such shares, is subject to prior compliance with the
Ohio Control Share Acquisition Act (which condition would be fulfilled by
shareholder approval to be sought at ADLT's annual meeting) and approval under
the HSR Act (which requires ADLT and GE to provide information to the federal
government to allow it to determine whether to contest an increase by GE to an
interest in ADLT in excess of 25% pursuant to antitrust law).

<PAGE>

CUSIP NO. 00753C 10 2                 13D

         If the proxies become effective after the Second Occurrence, GE will
have proxies to vote the Hellman Shares (defined as all shares owned or
controlled by Mr. Hellman and Hellman, LTD., currently approximately 3.9 million
shares) and will be entitled to exercise approximately 35% of the then
outstanding voting power of ADLT (assuming that none of the Hellman Shares have
been transferred by the beneficial owners and no issuance of additional shares
by ADLT other than pursuant to the GE transaction) or approximately 34% of the
voting power of ADLT on a fully diluted basis.

         Upon the Third Occurrence (defined below) under the Contingent Warrant
Agreement, GE (i) receives the right to vote the number of shares then owned by
Mr. Ruud, and the right to vote the number of shares as to which Mr. Ruud then
has voting power pursuant to the Ruud Voting Trust or Irrevocable Proxies
granted with respect to shares removed from the Ruud Voting Trust, currently
approximately 3.6 million shares (the "Ruud Shares"), and (ii) is granted an
additional warrant (the "Second Contingent Warrant") which will entitle GE to
purchase additional shares of Common Stock at the then current market price. The
number of shares subject to the Second Contingent Warrant will be the number of
shares necessary to give GE 50% plus one vote of the voting power of ADLT
(including the exercise of all outstanding Warrants, shares subject to
irrevocable proxies, the shares subject to the Second Contingent Warrant and all
proxies held with respect to Hellman Shares and Ruud Shares). The effectiveness
of this rights granted upon the Third Occurrence requires that the conditions
for the effectiveness of the proxies following the Second Occurrence have been
satisfied, and that any additional provisions of the Ohio Control Share
Acquisition Act required with respect to proxies or the Ruud Shares be
satisfied. If the proxies on the Ruud Shares become effective after the Third
Occurrence, GE will have the right to vote the Ruud Shares and will be entitled
to exercise approximately 48.4% of the then outstanding voting power of ADLT
(assuming that none of the Hellman Shares or the Ruud Shares have been sold by
the beneficial owners, no exercise by GE of the Contingent Warrants and no
issuance of additional shares by ADLT other than pursuant to the GE
transaction)..

         Subject to shareholder approval, after the Third Occurrence, if ADLT
issues additional shares of Common Stock to anyone other than GE, GE will be
entitled to purchase, on the same terms given to the third party, the number of
shares required to maintain GE's voting power.

         The basis for GE's additional rights upon the Second Occurrence and the
Third Occurrence is the failure of the Company to maintain a 2.0:1 ratio of
EBITDA (as defined) to Interest Expense (as defined) over the applicable
measurement periods. The first measurement period is the six months ended
December 31, 1999. Thereafter, the measurement periods are the six months ending
on the last day of each successive fiscal quarter until September 30, 2010. The
first failure to maintain the required ratio would be the "First Occurrence,"
the second such failure would be the "Second Occurrence" and the third such
failure would be the "Third Occurrence." However, after the First Occurrence, if
ADLT maintains the required ratio in the three fiscal quarters immediately prior
to the measurement period in which a failure occurs, a Second Occurrence or
Third Occurrence, as the case may be, would not be effective, if the Company
maintained the required ratio for the measurement period immediately following
the measurement period in which such occurrence would otherwise have been
effective. Under the terms of the transaction, EBITDA consists of net earnings,
plus interest expense, plus depreciation and amortization, plus income taxes,
less extraordinary gains and gains from asset sales plus extraordinary losses
and losses from asset sales. Interest Expense consists of interest expense (net
of interest income) calculated in accordance with generally accepted accounting
principles, but excludes amortization of deferred financing costs not exceeding
$125,000 in any fiscal quarter.

         Except as described below, the Reporting Person has no current plans or
proposals which relate to or would result in any of the events described in
Items (a) through (j) of Item 4 of Schedule 13D:

<PAGE>

CUSIP NO. 00753C 10 2                 13D

         (a) After the Second Occurrence under the Contingent Warrant Agreement,
GE is granted options from Messrs. Hellman and Ruud to purchase, at the then
current market price, that number of shares of Common Stock of ADLT which,
together with all other shares of ADLT then owned by GE, would represent 25% of
the voting power of the ADLT Common Stock. In addition, after the Second
Occurrence under the Contingent Warrant, GE is granted the First Contingent
Warrant to purchase additional shares of Common Stock of ADLT at the then
current market price. The number of shares subject to the First Contingent
Warrant will be equal to the number of shares required to allow GE to have a
majority of the voting power of ADLT, assuming GE had effective proxies with
respect to all shares as to which Messrs. Hellman and Ruud then have voting
power. The exercise of the First Contingent Warrant is subject to prior
compliance with the Ohio Control Share Acquisition Act (which condition would be
fulfilled by shareholder approval to be sought at ADLT's annual meeting) and
approval under the HSR Act (which requires ADLT and GE to provide information to
the federal government to allow it to determine whether to contest an increase
by GE to an interest in ADLT in excess of 25% pursuant to antitrust law). Upon
the Third Occurrence under the Contingent Warrant Agreement, GE is granted the
Second Contingent Warrant to purchase additional shares of Common Stock of ADLT
at the then current market price. The number of shares subject to the Second
Contingent Warrant will be the number of shares necessary to give GE 50% plus
one vote of the voting power of ADLT (including the exercise of all outstanding
Warrants, shares subject to irrevocable proxies, the shares subject to the
Second Contingent Warrant and all proxies held with respect to Hellman Shares
and Ruud Shares). In addition, subject to shareholder approval, after the Third
Occurrence, if ADLT issues additional shares of Common Stock to anyone other
than GE, GE will be entitled to purchase, on the same terms given to the third
party, the number of shares required to maintain GE's voting power.

         (b) To the best of the Reporting Person's knowledge, no such
transaction is contemplated.

         (c) To the best of the Reporting Person's knowledge, no such
transaction is contemplated.

         (d) Under the terms of the Stock Purchase Agreement, the Reporting
Person is entitled to propose five individuals none of whom are directors,
executive officers, employees or the beneficial owner of 10% or more of any
class of equity securities of the Reporting Person as potential members of the
Board of Directors of ADLT (the "Reporting Person's Nominees"). ADLT is required
to cause to be appointed to the Board of Directors of ADLT that number of the
Reporting Person's Nominees necessary to give the Reporting Person
representation equaling 20% of the total members of the Board of Directors of
ADLT. In addition, ADLT is required to at all times cause the number of the
Reporting Person's Nominees serving on the Board of Directors of ADLT to be
equal to the greater of (i) 20% of the number of members of the Board of
Directors, or (ii) that number of members of the Board of Directors that
corresponds most nearly to the Reporting Person's percentage ownership interest
in ADLT.

         (e) Except as described herein, the Reporting Person is not aware of
any changes to ADLT's present capitalization or dividend policy.

         (f) Except as described herein, the Reporting Person is not aware of
any material change in ADLT's business or corporate structure resulting from
this transaction.

         (g) Under the terms of the Stock Purchase Agreement, ADLT is required
to submit to a vote of its shareholders at its 1999 annual meeting a proposal to
amend its Articles of Incorporation to provide that Section 1701.831 of the Ohio
Revised Code shall not apply to "control share acquisitions" of shares of
capital stock of ADLT, and the Board of Directors of ADLT is required to
recommend to the shareholders of ADLT that they vote in favor of and adopt such
proposal. If adotped, such proposal may impede a change of control of ADLT. GE
is granted a put right with respect to the Series A Preferred Stock if ADLT
merges, sells all or a substantial portion of its assets (other than in the

<PAGE>

CUSIP NO. 00753C 10 2                 13D

ordinary course of business), or issues capital stock. The put right may impede
a change of control of ADLT. Under certain circumstances GE is granted various
options, proxies and warrants pursuant to the terms of the Contingent Warrant
Agreement described above. Once granted, these instruments may impede a change
of control. GE has a right of first refusal and co-sale right with respect to
sales of more than 1,000 shares by Wayne R. Hellman, Alan Ruud or Hellman, LTD.
These rights may impede a change of control of ADLT.

         (h) The Reporting Person is not aware of any such plan or proposal.

         (i) The Reporting Person is not aware of any such plan or proposal.

         (j) The Reporting Person is not aware of any such actions other than
those described herein.

prices for open market sales. The Reporting Person must exercise its right of
first refusal within twenty days of receiving notice (or within two days for
open market sales). The Reporting Person also has the right to participate in
any sales by Wayne R. Hellman, Alan J. Ruud or Hellman, LTD. of blocks of 1,000
shares or more.

         (c) OPTION AGREEMENT. The Reporting Person is granted an option from
each of Wayne R. Hellman and Alan J. Ruud to purchase shares upon a Second
Occurrence under the Contingent Warrant Agreement. The number of shares subject
to the options is the number of shares that when combined with other shares
owned by the Reporting Person will give the Reporting Person a 25% interest in
ADLT. The options must be exercised in full. The options generally last for one
year after the Reporting Person has received notice of the Second Occurrence.
The option price is current market price at the time of the Second Occurrence.
The Reporting Person's rights to exercise the option is subject to approval
under the HSR Act. The Option Agreement is among Wayne R.
Hellman, Alan J. Ruud and GE.

         (d) REGISTRATION RIGHTS AGREEMENT. GE and ADLT are parties to a
Registration Rights Agreement (the "Registration Rights Agreement") relating to
all common shares owned by GE (whether by virtue of conversion of the Series A
Preferred Stock, exercise of the Initial Warrant, the First Contingent Warrant
or the Second Contingent Warrant or otherwise). The Registration Rights
Agreement provides that GE may make one demand for a long-form registration and
unlimited demands for short-form registrations to have common shares owned by GE
registered pursuant to the Securities Act of 1933, as amended (the "Securities
Act"). These demand registration rights are subject to certain limitations as a
result of other stockholders exercising their demand rights. GE also has certain
"piggy-back" registration rights. GE must be notified prior to the filing of any
registration statement under the Securities Act by ADLT.

         (e) ARTICLES OF INCORPORATION. The express terms of the Series A
Preferred Stock include a number of put rights in favor of GE as well as a
mandatory redemption provision. The purchase price under all of GE's put rights
and under the mandatory redemption provision is the Liquidation Preference
Amount. The mandatory redemption date is September 30, 1999. GE has the right to
put the Series A Preferred Stock (i) on September 30, 2004 (the "General Put
Right"), (ii) if ADLT's shareholders do not adopt a proposal to "opt out" of the
Ohio Control Share Acquisition Act or do not approve the transaction in
accordance with NSDAAQ Rule 4460(i)(D) at ADLT's 1999 annual meeting, (iii) if
within 365 days after GE has filed its Notification and Report Form as required
under the HSR Act in connection with a Second Occurrence under the Contingent
Warrant Agreement ADLT and GE are unable to obtain required governmental
approval under the HSR Act or (iv) if ADLT takes any action to give effect to
certain major corporate actions, including actions to merge, sell all or a
substantial portion of its assets (other than in the ordinary course of
business), issue capital stock, or incur or have outstanding indebtedness for
borrowed money in excess of $210,000,000 (the "Occurrence Based Put Right"). If
ADLT does not purchase the Series A Preferred Stock within the applicable
closing period (generally a one year period from the date of notice of the put)
in connection with the General Put Right or the Occurrence Based Put Right, the
conversion ratio applicable to the Series A Preferred Stock increases from four
to one to eight to one. Under the terms of the Series A Preferred Stock, the
shares of Series A Preferred Stock are voted on an "as if" converted basis.

         (f) SECOND CONTINGENT WARRANT. The Second Contingent Warrant provides
that if ADLT issues additional shares of Common Stock to anyone other than GE,
GE will be entitled to purchase, on the same terms given to the third party, the
number of shares required to maintain GE's voting power.

SCHEDULE B TO SCHEDULE 13D

                    GE CONVICTIONS WITHIN THE PAST FIVE YEARS
                    -----------------------------------------

         Her Majesty's Inspectorate of Pollution v. IGE Medical Systems Limited
(St. Albans Magistrates Court, St. Albans, Hertsfordshire, England, Case No.
04/00320181)

         In April, 1994, GEMS' U.K. subsidiary, IGE Medical Systems Limited
(IGEMS) discovered the loss of a radioactive barium source at the Radlett,
England facility. The lost source, used to calibrate nuclear camera detectors,
emits a very low level of radiation. IGEMS immediately reported the loss as
required by the U.K. Radioactive Substances Act. An ensuing investigation,
conducted in cooperation with government authorities, failed to locate the
source. On July 21, 1994, Her Majesty's Inspectorate of Pollution (HMIP) charged
IGEMS with violating the Radioactive Substances Act by failing to comply with a
condition of registration. The Act provides that a registrant like IGEMS, which
"does not comply with a limitation or condition subject to which (it) is so
registered ... shall be guilty of (a criminal) offense." Condition 7 of IGEMS'
registration states that it "shall so far as is reasonably practicable prevent
 ... loss of any registered source."

         At the beginning of trial on February 24, 1995, IGEMS entered a guilty
plea and agreed to pay of fine of (pound)5,000 and assessed costs of
(pound)5,754. The prosecutor's presentation focused primarily on the 1991 change
in internal IGEMS procedures and, in particular, the source logging procedure.
The prosecutor complimented IGEMS' investigation and efforts to locate the
source and advised the court that IGEMS had no previous violations of the
Radioactive Substances Act. He also told the court that the Radlett plant had
been highlighted as an exemplary facility to HIMP inspectors as part of their
training. In mitigation, IGEMS emphasized the significant infrastructure and
expense undertaken by IGEMS to provide security for radiation sources and the
significant effort and expense incurred in attempting to locate the missing
source.

         Except for the foregoing, GE has not and, to the best of GE's
knowledge, none of the directors and executive officers of GE has been, during
the last five years, convicted in a criminal proceeding (excluding traffic
violations or similar misdemeanors).

          GE has not and, to the best of GE's knowledge, none of the directors
and executive officers of GE has been, during the last five years, a party to a
civil proceeding of a judicial or administrative body of competent jurisdiction
and as a result of such proceeding was or is subject to a judgment, decree, or
final order enjoining future violations of, or prohibiting or mandating
activities subject to, federal or state securities laws or finding any violation
with respect to such laws.

                                    SECTION 5

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         The Company represents and warrants to Purchaser as follows:

                  5.1 Organization; Authority. Each of the Company and each
Subsidiary: (a) is a corporation duly incorporated, validly existing and in good
standing under the laws of the State of its incorporation and (b) has all
requisite corporate power and authority to own its properties and to carry on
its business as now being conducted. Each of the Company and each Subsidiary is
qualified to do business in each state in which the nature of its business makes
such qualification necessary, except where failure to so qualify would not have
a material adverse effect on the Company. The Company has all requisite
corporate power and authority to enter into this Agreement and the Collateral
Agreements, to perform its obligations hereunder and thereunder, and to
consummate the transactions contemplated hereby and thereby. All necessary
corporate action has been (or will timely be) taken by and on behalf of the
Company and its shareholders with respect to the execution, delivery, and
performance by the Company of this Agreement and the Collateral Agreements and
the consummation of the transactions contemplated hereby and thereby. This
Agreement and the Collateral Agreements constitute (or will constitute when
executed and delivered) legal, valid, and binding obligations of the Company,
enforceable against the Company in accordance with their respective terms.
Neither the execution, delivery, and performance of this Agreement, the
Collateral Agreements, and the other instruments and transactions contemplated
hereby, nor the issuance of the Purchased Shares, the Warrant, the Warrant
Shares, the First Contingent Warrant, the Second Contingent Warrant, the
Contingent Shares or the Conversion Shares, will violate any provision of any
law (provided, with respect to the Warrant Shares, the Contingent Shares and the
Conversion Shares, that the Purchaser complies with applicable provisions of the
Ohio Control Share Acquisition Act), any order of any court or other agency of
government, the Amended Articles or Code of Regulations of the Company or any
agreement or instrument to which the Company is a party or by which the Company
is bound, or be in conflict with, result in a breach of, or constitute (with
notice or lapse of time, or both) a default under any such agreement or
instrument provided, however, that the purchase or redemption of Purchased
Shares upon exercise of the Put Option (as defined in the Amendment to Articles)
would violate (i) the terms of the Credit Agreement, unless prior consent of the
lenders thereunder is obtained and (ii) the terms of the Indenture, unless
Restricted Payments (as defined in the Indenture) in an amount equal to the
purchase price are then permitted pursuant to the terms of the Indenture.

                  5.2 Capitalization. The authorized capital stock of the
Company consists of (a) 80,000,000 Common Shares, of which 20,237,706 were
issued and outstanding on April 1, 1999, and (b) 1,000,000 Preferred Shares,
none of which are issued or outstanding. All of the issued and outstanding
Common Shares are duly authorized, validly issued, fully paid and nonassessable,
and were issued in conformity with all applicable state and federal securities
laws. All of the Preferred Shares are duly authorized. The Purchased Shares
shall have the rights, preferences and privileges set forth in the Amended
Articles. Except for the 3,279,254 Common Shares reserved for issuance under the
Stock Plans, the Company has no other equity securities of any class authorized,

<PAGE>

CUSIP NO. 00753C 10 2                 13D

issued, reserved for issuance, or outstanding. Except for the conversion right
contained in the Preferred Shares, the purchase rights contained in the
Contingent Warrant Agreement, and options and rights to shares issued under the
Stock Plans, there are no outstanding options, offers, warrants, conversion
rights, agreements, or other rights to subscribe for or to purchase from the
Company, or, except for Common Shares issued or to be issued in respect of
acquisitions of securities or assets of any Persons in connection with contracts
entered into prior to the date hereof (which in the aggregate do not exceed
110,000 Common Shares), commitments by the Company to issue, transfer, or sell
(either written or oral, formal or informal, firm or contingent) shares of or
interests in the capital stock or, except for the Company's obligations to use
its best efforts to effect the registration under the Securities Act of 8%
Senior Notes to be issued in exchange for 8% Senior Notes of the Company issued
in a private offering, other securities of the Company (whether debt, equity, or
a combination thereof) or obligating the Company to grant, extend or enter into
any such agreement or commitment. No securities of the Company carry, and no
shareholder of the Company has been granted, any preemptive rights. The Company
is not obligated under any agreement, arrangement or understanding to redeem or
otherwise purchase any of its shares of capital stock. Schedule 5.2 to the
Disclosure Statement lists, by creditor, the total Indebtedness for Borrowed
Money of the Company and its Subsidiaries as of May 1, 1999.

                  5.3 Financial Statements and Reports; Absence of Undisclosed
Liabilities. The Company has filed all forms, reports and documents with the
Securities and Exchange Commission required to be filed by it pursuant to the
Exchange Act, and the rules and regulations promulgated thereunder, all of which
have complied in all material respects with the applicable requirements of the
Exchange Act, and such rules and regulations (hereinafter collectively referred
to as the "Company Reports"). None of the Company Reports, at the time filed,
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. The financial statements of the Company included in the Company
Reports complied as to form in all material respects with applicable accounting
requirements and the published rules and regulations of the Commission applied
on a consistent basis (except as otherwise noted in such financial statements)
and present fairly in all material respects the financial position, results of
operations, cash flows and changes in financial position of the Company and its
consolidated Subsidiaries as of the dates stated or the periods indicated,
subject, in the case of unaudited interim consolidated financial statements, to
normal year-end adjustments. Except as reflected in the most recent financial
statements of the Company included in the Company Reports or obligations
incurred for the payment of money only in the ordinary course of business
consistent with past practice since the date of the most recent balance sheet
included in the Company Reports, the Company does not have any material
liabilities or obligations of any nature, whether accrued, contingent or
otherwise and whether due or to become due.

                  5.4 Securities. The Conversion Shares issuable upon conversion
of the Purchased Shares have been duly authorized and reserved for issuance and,
following issuance and delivery of the Purchased Shares in accordance with this
Agreement, upon conversion in accordance with the terms of the Purchased Shares,
the Conversion Shares shall be validly issued, fully paid, and nonassessable and
will be free of restrictions on transfers other than restrictions contained in
this Agreement and under applicable state and federal securities laws. The

<PAGE>

Warrant Shares issuable upon exercise of the Warrant and the Contingent Shares
issuable upon exercise of the First Contingent Warrant and the Second Contingent
Warrant have been duly authorized and reserved for issuance and, when payment is
made therefor in accordance with the Warrant or the First Contingent Warrant or
the Second Contingent Warrant, as the case may be, shall be validly issued,
fully paid, and nonassessable and will be free of restrictions on transfers
other than restrictions contained in this Agreement and under applicable state
and federal securities laws and subject to applicable provisions of the Ohio
Control Share Acquisition Act.

                  5.5 Securities Laws. No consent, authorization, approval,
permit, or order of or filing with any governmental or regulatory authority is
required under current laws and regulations in connection with the execution and
delivery of either this Agreement, or the offer, issuance, sale, or delivery of
the Purchased Shares, the Warrant, the Warrant Shares, the First Contingent
Warrant, the Second Contingent Warrant, the Contingent Shares or the Conversion
Shares to Purchaser (assuming the Conversion Shares are issued to Purchaser in
conformity with the terms hereof and thereof) other than the qualification
thereof or notification with respect thereto, if required, under applicable
federal and state securities laws, which qualification or notification has been
or will be effected as a condition of such sales. The Company has not: (a)
issued any securities in violation of the requirements of Section 5 of the
Securities Act or any other law; (b) violated any rule, regulation or
requirement under the Securities Act or the Exchange Act; (c) issued any
securities in violation of any state securities laws; or (d) redeemed any
securities in violation of any applicable state or federal securities law or any

                  5.6 No Preemptive Rights. No Person has any right of first
refusal or any preemptive rights in connection with the issuance of the
Purchased Shares or the Warrant, the issuance of the Warrant Shares upon
exercise of the Warrant, the issuance of the Contingent Shares upon exercise of
the First Contingent Warrant or the Second Contingent Warrant, the issuance of
the Conversion Shares upon conversion of the Purchased Shares, or any future
issuances of securities by the Company.

                  5.7 Registration Rights. Except as set forth in Schedule 5.7
to the Disclosure Statement and in the Registration Rights Agreement, the
Company is not under any contractual obligation to register with the Commission
any of its currently outstanding securities or any of its securities that may
hereafter be issued, other than the Company's obligation to use its best efforts
to effect the registration under the Securities Act of 8% Senior Notes.

                  5.8 Compliance with Laws. Each of the Company and each

                  10.4 Waiver. No delay on the part of any party hereto with
respect to the exercise of any right, power, privilege, or remedy under this
Agreement or the Collateral Agreements shall operate as a waiver thereof, nor
shall any exercise or partial exercise of any such right, power, privilege, or
remedy preclude any further exercise thereof or the exercise of any other right,
power, privilege, or remedy. No modification or waiver by either party hereto of
any provision of this Agreement, the Collateral Agreements, the Warrant or of
the Purchased Shares, or consent to any departure by the other party therefrom,
shall be effective in any event unless in writing as set forth in Section 10.14,
and then only in the specific instance and for the purpose for which given.
Notwithstanding the foregoing, each party hereto shall have the right to waive
compliance by the other party with any of the provisions hereof, or to modify
such provisions to a less restrictive obligation of the other party on such
terms as such party shall determine, with or without prior notice to the other
party.

                  10.5 Remedies. The rights, powers, privileges, and remedies
hereunder, and under the Purchased Shares, the Warrant and the Collateral
Agreements, are cumulative and not exclusive of any other right, power,
privilege, or remedy the parties hereto would otherwise have.

                  10.6 Entire Agreement. This Agreement and the Collateral
Agreements constitute the entire agreement and understanding among Purchaser and
the Company, and supersede all prior agreements and understandings relating to
the subject matter hereof.

                  10.7 Law Governing. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York, without regard
to principles of conflicts of law.

                  10.8 Counterparts. This Agreement may be executed in
counterparts, each of which shall be deemed an original but all of which
together shall constitute one and the same instrument.

<PAGE>

CUSIP NO. 00753C 10 2                 13D

or unenforceability without invalidating the remaining provisions of this
Agreement or Collateral Agreement affecting the validity or enforceability of
such provision in any other jurisdiction.

                  10.10 Cross-References. References in this Agreement or in any

schedules to this Agreement are incorporated into and constitute an integral
part of this Agreement.

                  10.13 Conflict. In the event, and to the extent, that any
terms or provisions of the Company's Articles of Incorporation or Code of
Regulations are amended after the date hereof in violation of Section 8.1
contrary to the terms of this Agreement, the terms of this Agreement shall
control.

                  10.14 Amendment and Waiver. Except as otherwise provided
herein, no modification, amendment or waiver of any provision of this Agreement
will be effective unless such modification, amendment or waiver is approved in
writing by the Company and Purchaser. The failure of any party to enforce any of
the provisions of this Agreement will in no way be construed as a waiver of such
provisions and will not affect the right of such party thereafter to enforce
each and every provision of this Agreement.

                  10.15 Survival of Representations and Warranties. The
representations and warranties of the Company and Purchaser hereunder shall
survive the Closing for a period of three (3) years commencing on the Closing

THIS WARRANT AND THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE TRANSFERRED IN
VIOLATION OF SUCH ACT, THE RULES AND REGULATIONS THEREUNDER OR THE PROVISIONS OF
THIS WARRANT.




                                SERIES A1 WARRANT

                          To Purchase Common Shares of

                      ADVANCED LIGHTING TECHNOLOGIES, INC.

                  THIS IS TO CERTIFY THAT GENERAL ELECTRIC COMPANY, or
registered assigns, is entitled, at any time during the Exercise Period (as
hereinafter defined), to purchase from ADVANCED LIGHTING TECHNOLOGIES, INC., an
Ohio corporation (the "Company"), up to 1,000,000 Common Shares (as hereinafter
defined and subject to adjustment as provided herein) as described herein, in
whole or in part, including fractional parts, at a purchase price of $.01 per
share (subject to adjustment as provided herein) all on the terms and conditions
and pursuant to the provisions hereinafter set forth.

1.   DEFINITIONS

                  Terms used in this Warrant have the respective meanings set
forth below:

                  "Additional Issuance" shall have the meaning set forth in
Section 4.3(a).

                  "Additional Common Shares" shall mean all Common Shares issued
by the Company after the date hereof, other than Conversion Shares, Contingent
Shares or Warrant Shares.

                  "Appraised Value" shall mean, in respect of any Common Share
on any date herein specified, the fair saleable value of such Common Share
(determined without giving affect to the discount for (i) a minority interest or
(ii) any lack of liquidity of the Common Share or (iii) to the fact that the
Company may have no class of equity registered under the Exchange Act) based on
the equity value of the Company, as determined by an investment banking or
valuation firm selected in accordance with the following sentences, divided by
the number of Common Shares outstanding on a Fully Diluted Basis as determined
in accordance with GAAP (assuming the payment of the exercise prices for such
shares). The determination of the Appraised Value per Common Share shall be made
by an investment banking or valuation firm of nationally recognized standing
selected by the Company and acceptable to the Majority Holders. If the
investment banking or valuation firm selected by Company is not acceptable to
the Majority Holders and the Company and the Majority Holders cannot agree on a
mutually acceptable investment banking or valuation firm, then the Majority
Holders and the Company shall each choose one such investment banking or
valuation firm and the respective chosen firms shall agree on another investment
banking or valuation firm which shall make the determination. The Company shall
retain, at its sole cost, such investment banking or valuation firm as may be
necessary for the determination of Appraised Value required by the terms of this
Warrant.

indicates) a Common Share, $0.001 par value, of the Company as constituted on
the date hereof, and any capital stock into which such Common Share may
thereafter be changed, and shall also include (i) capital stock of the Company
of any other class (regardless of how denominated) issued to the holders of
Common Shares upon any reclassification thereof which is also not preferred as
to dividends or assets over any other class of capital stock of the Company and
which is not subject to redemption and (ii) capital stock of any successor or
acquiring corporation (as defined in Section 4.8) received by or distributed to
the holders of Common Shares of the Company in the circumstances contemplated by

2.   EXERCISE OF WARRANT

                  2.1. Manner of Exercise. From and after the date hereof and
until 5:00 P.M., New York time, on the Expiration Date (the "Exercise Period"),
subject to the last sentence of this Section 2.1, Holder may exercise this
Warrant, on any Business Day, for all or any part of 1,000,000 Common Shares. In
order to exercise this Warrant, in whole or in part, Holder shall deliver to the
Company at its principal office at 32000 Aurora Road, Solon, Ohio 44139, or at
the office or agency designated by the Company pursuant to Section 12: (i) a
written notice of Holder's election to exercise this Warrant, which notice shall
specify the number of Common Shares to be purchased, (ii) payment of the Warrant
Price and (iii) this Warrant. Such notice shall be substantially in the form of
the subscription form appearing at the end of this Warrant as Exhibit A, duly
executed by Holder or its agent or attorney. Upon receipt thereof, the Company
shall, as promptly as practicable, and in any event within five Business Days
thereafter, execute or cause to be executed and deliver or cause to be delivered
to Holder a certificate or certificates representing the aggregate number of
full Common Shares issuable upon such exercise, together with cash in lieu of
any fraction of a share, as hereinafter provided. The share certificate or
certificates so delivered shall be, to the extent possible, in such denomination
or denominations as such Holder shall request in the notice and shall be
registered in the name of Holder or, subject to Section 9, such other name as
shall be designated in the notice. This Warrant shall be deemed to have been
exercised and such certificate or certificates shall be deemed to have been
issued, and Holder or any other Person so designated to be named therein shall
be deemed to have become a holder of record of such shares for all purposes, as
of the date the notice, together with the cash or check or other payment as
provided below and this Warrant, is received by the Company as described above
and all taxes required to be paid by Holder, if any, pursuant to Section 2.2
prior to the issuance of such shares have been paid. If this Warrant shall have
been exercised in part, the Company shall, at the time of delivery of the
certificate or certificates representing Warrant Shares, deliver to Holder a new
Warrant evidencing the rights of Holder to purchase the unpurchased Common
Shares called for by this Warrant, which new Warrant shall in all other respects
be identical with this Warrant, or, at the request of Holder, appropriate
notation may be made on this Warrant and the same returned to Holder. Payment of
the Warrant Price shall be made at the option of Holder by (i) certified or
official bank check, and/or (ii) by Holder's surrender to the Company of that
number of Warrant Shares (or the right to receive such number of shares) or
Common Shares having an aggregate Current Market Price equal to or greater than
the Current Warrant Price for all shares then being purchased (including those
being surrendered), or (iii) any combination thereof, duly endorsed by or
accompanied by appropriate instruments of transfer duly executed by Holder or by
Holder's attorney duly authorized in writing. This Warrant and Holder's right to
exercise this Warrant shall, to the extent not previously exercised, terminate
at such time as GE has received the Put Option Purchase Price (as defined in
Section VII(c) of the Company's Second Amended and Restated Articles) upon an
HSR Triggered Put.

                  2.2. Payment of Taxes. All Common Shares issuable upon the
exercise of this Warrant pursuant to the terms hereof shall be validly issued,
fully paid and nonassessable and without any preemptive rights. The Company
shall pay all expenses in connection with, and all taxes and other governmental
charges that may be imposed with respect to, the issue or delivery thereof,
unless such tax or charge is imposed by law upon Holder, in which case such
taxes or charges shall be paid by Holder. The Company shall not be required,

<PAGE>

CUSIP NO. 00753C 10 2                 13D

however, to pay any tax or other charge imposed in connection with any transfer
involved in the issue of any certificate for Common Shares issuable upon
exercise of this Warrant in any name other than that of Holder, and in such case
the Company shall not be required to issue or deliver any share certificate
until such tax or other charge has been paid or it has been established to the
reasonable satisfaction of the Company that no such tax or other charge is due.

                  2.3. Fractional Shares. The Company shall not be required to
issue a fractional Common Share upon exercise of any Warrant. If any fraction of
a share would, but for this Section, be issuable upon exercise of this Warrant,
in lieu of such fractional share, the Company may, at its option, pay a cash
adjustment in respect of such final fraction in an amount equal to the same
fraction of the Current Market Price per Common Share on the date of exercise
or, if there is no Current Market Price on such date, $6.75 per whole Common
Share, adjusted to reflect equitably share dividends, subdivisions and
combinations after the date hereof.

                  2.4. Continued Validity. A holder of Common Shares issued upon
the exercise of this Warrant, in whole or in part (other than a holder who
acquires such shares after the same have been publicly sold pursuant to a
Registration Statement under the Securities Act or sold pursuant to Rule 144
thereunder), shall continue to be entitled with respect to such shares to all
rights to which it would have been entitled as Holder under Sections 9, 10 and
15 of this Warrant. The Company will, at the time of each exercise of this
Warrant, in whole or in part, upon the request of the holder of the Common
Shares issued upon such exercise hereof, acknowledge in writing, in form
reasonably satisfactory to such holder, its continuing obligation to afford to
such holder all such rights; provided, however, that if such holder shall fail
to make any such request, such failure shall not affect the continuing
obligation of the Company to afford to such holder all such rights.

3.   TRANSFER, DIVISION AND COMBINATION

                  3.1. Transfer. Subject to compliance with Section 9 hereof,
transfer of this Warrant and all rights hereunder, in whole or in part, shall be
registered on the books of the Company to be maintained for such purpose, upon
surrender of this Warrant at the principal office of the Company referred to in
Section 2.1 or the office or agency designated by the Company pursuant to
Section 12, together with a written assignment of this Warrant substantially in
the form of Exhibit B hereto duly executed by Holder or its agent or attorney
and funds sufficient to pay any transfer taxes payable upon the making of such
transfer. Upon such surrender and, if required, such payment, the Company shall,
subject to Section 9, execute and deliver a new Warrant or Warrants in the name
of the assignee or assignees and in the denomination specified in such
instrument of assignment, and shall issue to the assignor a new Warrant
evidencing the portion of this Warrant not so assigned, and this Warrant shall
promptly be canceled. A Warrant, if properly assigned in compliance with Section
9, may be exercised by a new Holder for the purchase of Common Shares without
having a new Warrant issued.

                  3.2. Division and Combination. Subject to Section 9, this
Warrant may be divided or combined with other Warrants upon presentation hereof
at the aforesaid office or agency of the Company, together with a written notice
specifying the names and denominations in which new Warrants are to be issued,
signed by Holder or its agent or attorney. Subject to compliance with Section
3.1 and with Section 9, as to any transfer that may be involved in such division
or combination, the Company shall execute and deliver a new Warrant or Warrants
in exchange for the Warrant or Warrants to be divided or combined in accordance
with such notice.

                  3.3. Expenses. The Company shall prepare, issue and deliver at
its own expense (other than transfer taxes) the new Warrant or Warrants under
this Section 3.

<PAGE>

CUSIP NO. 00753C 10 2                 13D


                  3.4. Maintenance of Books. The Company agrees to maintain, at
its aforesaid office or agency, books for the registration and the registration
of transfer of the Warrants.

4.   ADJUSTMENTS

                  Subject to NASDAQ Approval, the number of Common Shares for
which this Warrant is exercisable shall be subject to adjustment from time to
time as set forth in this Section 4. The Company shall give each Holder notice
of any event described below in accordance with Section 5.1.

                  4.1. Share Dividends, Subdivisions and Combinations. If at any
time the Company shall:

                  (a) take a record of the holders of its Common Shares for the
purpose of entitling them to receive a dividend payable in, or other
distribution of, Additional Common Shares,

                  (b) subdivide its outstanding Common Shares into a larger
number of Common Shares, or

                  (c) combine its outstanding Common Shares into a smaller
number of Common Shares,

then the number of Common Shares for which this Warrant is exercisable
immediately after the occurrence of any such event shall be adjusted to equal
the number of Common Shares that a record holder of the same number of Common
Shares for which this Warrant is exercisable immediately prior to the occurrence
of such event would own or be entitled to receive after the happening of such
event.

                  4.2 Certain Other Distributions and Adjustments. (a) If at any
time the Company shall take a record of the holders of its Common Shares for the
purpose of entitling them to receive any dividend or other distribution of:

                  (i) cash,

                  (ii) any evidences of its indebtedness, any shares of its
         stock or any other securities or property of any nature whatsoever
         (other than cash, Convertible Securities or Additional Common Shares),
         or

                  (iii) any warrants or other rights to subscribe for or
         purchase any evidences of its indebtedness, any shares of its stock or
         any other securities or property of any nature whatsoever (other than
         cash, Convertible Securities or Additional Common Shares),

then Holder shall be entitled to receive such dividend or distribution as if
Holder had exercised this Warrant.

                  (b) A reclassification of the Common Shares (other than a
change in par value, or from par value to no par value or from no par value to
par value) into Common Shares and shares of any other class of stock shall be
deemed a distribution by the Company to the holders of its Common Shares of such
shares of such other class of stock within the meaning of paragraph (a) above

<PAGE>

CUSIP NO. 00753C 10 2                 13D

and, if the outstanding Common Shares shall be changed into a larger or smaller
number of Common Shares as a part of such reclassification, such change shall be
deemed a subdivision or combination, as the case may be, of the outstanding
Common Shares within the meaning of Section 4.1.

                  4.3. Issuance of Additional Common Shares. (a) If at any time
the Company shall (except as hereinafter provided) issue or sell any Additional
Common Shares or any security convertible or exchangeable into Additional Common
Shares (an "Additional Issuance"), other than Permitted Issuances, in exchange
for consideration in an amount per Additional Common Share less than either the
Purchase Price or the Current Market Price on the date of such Additional
Issuance (before giving effect to such Additional Issuance), then, effective
upon such Additional Issuance, the number of Common Shares subject to purchase
upon exercise of this Warrant shall be increased to a number determined by
multiplying the number of Common Shares subject to purchase immediately before
such Additional Issuance by a fraction, the numerator of which shall be the
number of Common Shares outstanding immediately prior to such Additional
Issuance plus the number of Additional Common Shares so issued and the
denominator of which shall be the number of Common Shares outstanding
immediately prior to such issuance of Additional Common Shares plus the number
of Common Shares which the aggregate consideration received by the Company for
the total number of Additional Common Shares so issued would purchase at the
greater of the Purchase Price or the Current Market Value at the time of such
Additional Issuance. In computing adjustments under this paragraph, fractional
interests in Common Shares shall be taken into account to the nearest
one-thousandth of a share.

                  (b) The provision of paragraph (a) of Section 4.3 shall not
apply to any issuance of Additional Common Shares for which an adjustment is
provided under Section 4.1 or 4.2. No adjustment of the number of Common Shares
for which this Warrant shall be exercisable shall be made under paragraph (a) of
Section 4.3 upon the issuance of any Additional Common Shares that are issued
pursuant to the exercise of any warrants or other subscription or purchase
rights or pursuant to the exercise of any conversion or exchange rights in any
Convertible Securities, if any such adjustment shall previously have been made
upon the issuance of such warrants or other rights or upon the issuance of such
Convertible Securities (or upon the issuance of any warrant or other rights
therefor) pursuant to Section 4.4 or Section 4.5.

                  4.4. Issuance of Warrants or Other Rights. If at any time the
Company shall take a record of the holders of its Common Shares for the purpose
of entitling them to receive a distribution of, or shall in any manner (whether
directly or by assumption in a merger in which the Company is the surviving
corporation) issue or sell, any warrants or other rights to subscribe for or
purchase any Additional Common Shares or any Convertible Securities, whether or
not the rights to exchange or convert thereunder are immediately exercisable,
and the price per share for which a Common Share is issuable upon the exercise
of such warrants or other rights or upon conversion or exchange of such
Convertible Securities shall be less than either the Purchase Price or the
Current Market Price on the date of such issue or sale, then the number of
Common Shares for which this Warrant is exercisable shall be adjusted as
provided in Section 4.3 on the basis that the maximum number of Additional
Common Shares issuable pursuant to all such warrants or other rights necessary
to effect the conversion or exchange of all such Convertible Securities shall be
deemed to have been issued and outstanding and the Company shall be deemed to
have received all of the consideration payable therefor, if any, as of the date
of the issuance of such warrants or other rights. No further adjustments of the
number of Common Shares for which this Warrant is exercisable shall be made upon
the actual issue of such Common Shares or of such Convertible Securities upon
exercise of such warrants or other rights or upon the actual issue of such
Common Shares upon such conversion or exchange of such Convertible Securities.

<PAGE>

CUSIP NO. 00753C 10 2                 13D


                  4.5. Issuance of Convertible Securities. If at any time the
Company shall take a record of the holders of its Common Shares for the purpose
of entitling them to receive a distribution of, or shall in any manner (whether
directly or by assumption in a merger in which the Company is the surviving
corporation) issue or sell, any Convertible Securities, whether or not the
rights to exchange or convert thereunder are immediately exercisable, and the
price per share for which a Common Share is issuable upon such conversion or
exchange shall be less than either the Purchase Price or the Current Market
Price on the date of such issue or sale, then the number of Common Shares for
which this Warrant is exercisable shall be adjusted as provided in Section 4.3
on the basis that the maximum number of Additional Common Shares necessary to
effect the conversion or exchange of all such Convertible Securities shall be
deemed to have been issued and outstanding and the Company shall have received
all of the consideration payable therefor, if any, as of the date of issuance of
such Convertible Securities. No adjustment of the number of Common Shares for
which this Warrant is exercisable shall be made under this Section 4.5 upon the
issuance of any Convertible Securities that are issued pursuant to the exercise
of any warrants or other subscription or purchase rights therefor, if any such
adjustment shall previously have been made upon the issuance of such warrants or
other rights pursuant to Section 4.4. No further adjustments of the number of
Common Shares for which this Warrant is exercisable shall be made upon the
actual issue of such Common Shares upon conversion or exchange of such
Convertible Securities and, if any issue or sale of such Convertible Securities
is made upon exercise of any warrant or other right to subscribe for or to
purchase any such Convertible Securities for which adjustments of the number of
Common Shares for which this Warrant is exercisable have been or are to be made
pursuant to other provisions of this Section 4, no further adjustments of the
number of Common Shares for which this Warrant is exercisable and the Current
Warrant Price shall be made by reason of such issue or sale.

                  4.6. Superseding Adjustment. If, at any time after any
adjustment of the number of Common Shares for which this Warrant is exercisable
shall have been made pursuant to Section 4.4 or Section 4.5 as the result of any
issuance of warrants, rights or Convertible Securities,

                  (a) such warrants or rights, or the right of conversion or
exchange in such other Convertible Securities, shall expire, and all or a
portion of such warrants or rights, or the right of conversion or exchange with
respect to all or a portion of such other Convertible Securities, as the case
may be, shall not have been exercised, or

                  (b) the consideration per share for which Common Shares are
issuable pursuant to such warrants or rights, or the terms of such other
Convertible Securities, shall be increased solely by virtue of provisions
therein contained for an automatic increase in such consideration per share upon
the occurrence of a specified date or event,

then for each outstanding Warrant such previous adjustment shall be rescinded
and annulled and the Additional Common Shares that were deemed to have been
issued by virtue of the computation made in connection with the adjustment so
rescinded and annulled shall no longer be deemed to have been issued by virtue
of such computation. Thereupon, a recomputation shall be made of the effect of
such rights or options or other Convertible Securities on the basis of

                  (c) treating the number of Additional Common Shares or other
property, if any, theretofore actually issued or issuable pursuant to the
previous exercise of any such warrants or rights or any such right of conversion
or exchange, as having been issued on the date or dates of any such exercise and
for the consideration actually received and receivable therefor, and

<PAGE>

CUSIP NO. 00753C 10 2                 13D


                  (d) treating any such warrants or rights or any such other
Convertible Securities that then remain outstanding as having been granted or
issued immediately after the time of such increase of the consideration per
share for which Common Shares or other property are issuable under such warrants
or rights or other Convertible Securities; whereupon a new adjustment of the
number of Common Shares for which this Warrant is exercisable shall be made,
which new adjustment shall supersede the previous adjustment so rescinded and
annulled.

                  4.7. Other Provisions Applicable to Adjustments under this
Section. The following provisions shall be applicable to the making of
adjustments of the number of Common Shares for which this Warrant is exercisable
and the Current Warrant Price provided for in this Section 4:

                  (a) Computation of Consideration. To the extent that any
Additional Common Shares or any Convertible Securities or any warrants or other
rights to subscribe for or purchase any Additional Common Shares or any
Convertible Securities shall be issued for cash consideration, the consideration
received by the Company therefor shall be the amount of the cash received by the
Company therefor, or, if such Additional Common Shares or Convertible Securities
are offered by the Company for subscription, the subscription price, or, if such
Additional Common Shares or Convertible Securities are sold to underwriters or
dealers for public offering without a subscription offering, the initial public
offering price (in any such case subtracting any amounts paid or receivable for
accrued interest or accrued dividends and without taking into account any
compensation, discounts or expenses paid or incurred by the Company for and in
the underwriting of, or otherwise in connection with, the issuance thereof). To
the extent that such issuance shall be for a consideration other than cash,
then, except as herein otherwise expressly provided, the amount of such
consideration shall be deemed to be the fair value of such consideration at the
time of such issuance as determined in good faith by the Board of Directors of
the Company. In case any Additional Common Shares or any Convertible Securities
or any warrants or other rights to subscribe for or purchase such Additional
Common Shares or Convertible Securities shall be issued in connection with any
merger in which the Company issues any securities, the amount of consideration
therefor shall be deemed to be the fair value, as determined in good faith by
the Board of Directors of the Company, of such portion of the assets and
business of the nonsurviving corporation as such Board in good faith shall
determine to be attributable to such Additional Common Shares, Convertible
Securities, warrants or other rights, as the case may be. The consideration for
any Additional Common Shares issuable pursuant to any warrants or other rights
to subscribe for or purchase the same shall be the consideration received by the
Company for issuing such warrants or other rights plus the additional
consideration payable to the Company upon exercise of such warrants or other
rights. The consideration for any Additional Common Shares issuable pursuant to
the term of any Convertible Securities shall be the consideration received by
the Company for issuing warrants or other rights to subscribe for or purchase
such Convertible Securities, plus the consideration paid or payable to the
Company in respect of the subscription for or purchase of such Convertible
Securities, plus the additional consideration, if any, payable to the Company
upon the exercise of the right of conversion or exchange in such Convertible
Securities. In case of the issuance at any time of any Additional Common Shares
or Convertible Securities in payment or satisfaction of any dividends upon any
class of stock other than Common Shares, the Company shall be deemed to have
received for such Additional Common Shares or Convertible Securities a
consideration equal to the amount of such dividend so paid or satisfied.

                  (b) When Adjustments to Be Made. The adjustments required by
this Section 4 shall be made whenever and as often as any specified event
requiring an adjustment shall occur, except that any adjustment of the number of
Common Shares for which this Warrant is exercisable that would otherwise be
required may be postponed (except in the case of a subdivision or combination of
Common Shares, as provided for in Section 4.1) up to, but not beyond the date of
exercise if such adjustment either by itself or with other adjustments not
previously made adds or subtracts less than 1% of the Common Shares for which

<PAGE>

CUSIP NO. 00753C 10 2                 13D

this Warrant is exercisable immediately prior to the making of such adjustment.
Any adjustment representing a change of less than such minimum amount (except as
aforesaid) that is postponed shall be carried forward and made as soon as such
adjustment, together with other adjustments required by this Section 4 and not
previously made, would result in a minimum adjustment or on the date of
exercise. For the purpose of any adjustment, any specified event shall be deemed
to have occurred at the close of business on the date of its occurrence.

                  (c) Fractional Interests. In computing adjustments under this
Section 4, fractional interests in Common Shares shall be taken into account to
the nearest 1/1000th of a share.

                  (d) When Adjustment Not Required. If the Company shall take a
record of the holders of its Common Shares for the purpose of entitling them to
receive a dividend or distribution or subscription or purchase rights and shall,
thereafter and before the distribution to shareholders thereof, legally abandon
its plan to pay or deliver such dividend, distribution, subscription or purchase
rights, then thereafter no adjustment shall be required by reason of the taking
of such record and any such adjustment previously made in respect thereof shall
be rescinded and annulled.

                  (e) Escrow of Warrant Shares. If after any property becomes
distributable pursuant to this Section 4 by reason of the taking of any record
of the holders of Common Shares, but prior to the occurrence of the event for
which such record is taken, and Holder exercises this Warrant, any Additional
Common Shares issuable upon exercise by reason of such adjustment shall be
deemed the last Common Shares for which this Warrant is exercised
(notwithstanding any other provision to the contrary herein) and such shares or
other property shall be held in escrow for Holder by the Company to be issued to
Holder upon and to the extent that the event actually takes place, upon payment
of the then Current Warrant Price. Notwithstanding any other provision to the
contrary herein, if the event for which such record was taken fails to occur or
is rescinded, then such escrowed shares shall be canceled by the Company and
escrowed property returned to the Company.

                  (f) Challenge to Good Faith Determination. Whenever the Board
of Directors of the Company shall be required to make a determination in good
faith of the fair value of any item under this Section 4, such determination may
be challenged in good faith by the Majority Holders, and any dispute shall be
resolved by an investment banking or valuation firm of recognized national
standing selected by the Company and acceptable to the Majority Holders.

                  (g) Prohibition on Adjustment. The provisions of Section 4.3,
4.4 and 4.5 shall not operate to reduce the number of Common Shares subject to
purchase upon exercise of this Warrant.

                  4.8. Reorganization, Reclassification, Merger, Consolidation
or Disposition of Assets. In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation or where there
is a change in or distribution with respect to the Common Shares), or sell,
transfer or otherwise dispose of all or substantially all its property, assets
or business to another corporation and, pursuant to the terms of such
reorganization, reclassification, merger, consolidation or disposition of
assets, Common Shares of the successor or acquiring corporation, or any cash,
shares of stock or other securities or property of any nature whatsoever
(including warrants or other subscription or purchase rights) in addition to or
in lieu of common stock of the successor or acquiring corporation ("Other
Property"), are to be received by or distributed to the holders of Common Shares
of the Company, then each Holder shall have the right thereafter to receive,
upon exercise of such Warrant, the number of Common Shares of the successor or
acquiring corporation or of the Company, if it is the surviving corporation, and
Other Property receivable upon or as a result of such reorganization,
reclassification, merger, consolidation or disposition of assets by a holder of
the number of Common Shares for which this Warrant is exercisable immediately
prior to such event. In case of any such reorganization, reclassification,

<PAGE>

CUSIP NO. 00753C 10 2                 13D

merger, consolidation or disposition of assets, the successor or acquiring
corporation (if other than the Company) shall expressly assume the due and
punctual observance and performance of each and every covenant and condition of
this Warrant to be performed and observed by the Company and all the obligations
and liabilities hereunder, subject to such modifications as may be deemed
appropriate (as determined by resolution of the Board of Directors of the
Company) in order to provide for adjustments of Common Shares for which this
Warrant is exercisable which shall be as nearly equivalent as practicable to the
adjustments provided for in this Section 4. For purposes of this Section 4.8,
"common stock of the successor or acquiring corporation" shall include stock of
such corporation of any class that is not preferred as to dividends or assets
over any other class of stock of such corporation and that is not subject to
redemption and shall also include any evidences of indebtedness, shares of stock
or other securities that are convertible into or exchangeable for any such
stock, either immediately or upon the arrival of a specified date or the
happening of a specified event and any warrants or other rights to subscribe for
or purchase any such stock. The foregoing provisions of this Section 4.8 shall
similarly apply to successive reorganizations, reclassifications, mergers,
consolidations or disposition of assets.

                 4.9. Other Action Affecting Common Shares. In case at any time
or from time to time the Company shall take any action in respect of its Common
Shares, other than any action described in this Section 4, then, unless such
action will not have a materially adverse effect upon the rights of Holders, the
number of Common Shares or other stock for which this Warrant is exercisable
and/or the purchase price thereof shall be adjusted in such manner as may be
equitable in the circumstances.

5.   NOTICES TO WARRANT HOLDERS

                 5.1. Notice of Adjustments. Not less than 10 nor more than 30
days prior to the record date or effective date, as the case may be, of any
action that requires or might require an adjustment or readjustment pursuant to
Section 4, the Company shall forthwith prepare and deliver to each Holder a
signed copy of a certificate executed by the chief financial officer of the
Company setting forth, in reasonable detail, the event requiring the adjustment
and the method by which such adjustment was calculated (including a description
of the basis on which the Board of Directors of the Company determined the fair
value of any evidences of indebtedness, shares of stock, other securities or
property or warrants or other subscription or purchase rights referred to in
Section 4.7 (a)), specifying the number of Common Shares for which this Warrant
is exercisable and (if such adjustment was made pursuant to Section 4.8 or 4.9)
describing the number and kind of any other shares of stock or Other Property
for which this Warrant is exercisable, and any change in the purchase price or
prices thereof, after giving effect to such adjustment or change. The Company
shall keep at its office or agency designated pursuant to Section 12 copies of
all such certificates and cause the same to be available for inspection at said
office during normal business hours by any Holder or any prospective purchaser
of a Warrant designated by a Holder thereof.

                  5.2.     Notice of Corporate Action.  If at any time

                  (a) the Company shall take a record of the holders of its
Common Shares for the purpose of entitling them to receive a dividend or other
distribution, or any right to subscribe for or purchase any evidences of its
indebtedness, any shares of stock of any class or any other securities or
property, or to receive any other right, or

                  (b) there shall be any capital reorganization of the Company,
any reclassification or recapitalization of the capital stock of the Company or
any consolidation or merger of the Company with, or any sale, transfer or other
disposition of all or substantially all the property, assets or business of the
Company to, another corporation, person or entity, or

<PAGE>

CUSIP NO. 00753C 10 2                 13D

                  (c) there shall be a voluntary or involuntary dissolution,
liquidation or winding up of the Company;

then, in any one or more of such cases, the Company shall give to Holder (i) at
least 20 days prior written notice of the date on which a record date shall be
selected for such dividend, distribution or right or for determining rights to
vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, dissolution, liquidation or winding
up, and (ii) in the case of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, dissolution, liquidation or winding
up, at least 30 days prior written notice of the date when the same shall take
place. Such notice in accordance with the foregoing clause also shall specify
(i) the date on which any such record is to be taken for the purpose of such
dividend, distribution or right, the date on which the holders of Common Shares
shall be entitled to any such dividend, distribution or right, and the amount
and character thereof, and (ii) the date on which any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up is to take place and the time, if any
such time is to be fixed, as of which the holders of Common Shares shall be
entitled to exchange their Common Shares for securities or other property
deliverable upon such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up. Each such
written notice shall be sufficiently given if addressed to Holder at the last
address of Holder appearing on the books of the Company and delivered in
accordance with Section 15.2.

6.       NO IMPAIRMENT

                  The Company shall not by any action, including, without
limitation, amending its articles of incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant, but will at all
times in good faith assist in the carrying out of all such terms and in the
taking of all such actions as may be necessary or appropriate to protect the
rights of Holder against impairment. Without limiting the generality of the
foregoing, the Company will (a) take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid
and nonassessable Common Shares upon the exercise of this Warrant, including
taking such action as is necessary for the Current Warrant Price to be not less
than the par value of the Common Shares issuable upon exercise of this Warrant,
and (b) use its best efforts to obtain all such authorizations, exemptions or
consents from any public regulatory body having jurisdiction thereof as may be
necessary to enable the Company to perform its obligations under this Warrant.

                  Upon the request of Holder, the Company will at any time
during the period this Warrant is outstanding acknowledge in writing, in form
satisfactory to Holder, the continuing validity of this Warrant and the
obligations of the Company hereunder.

7.   RESERVATION AND AUTHORIZATION OF COMMON SHARES; REGISTRATION WITH OR
     APPROVAL OF ANY GOVERNMENTAL AUTHORITY

                  From and after the date hereof, the Company shall at all times
reserve and keep available for issue upon the exercise of Warrants such number
of its authorized but unissued Common Shares as will be sufficient to permit the
exercise in full of all outstanding Warrants. All Common Shares that shall be so
issuable, when issued upon exercise of any Warrant and payment therefor in

<PAGE>

CUSIP NO. 00753C 10 2                 13D

accordance with the terms of such Warrant, shall be duly and validly issued and
fully paid and nonassessable, and not subject to preemptive rights.

                  Before taking any action that would result in an adjustment in
the number of Common Shares for which this Warrant is exercisable, the Company
shall obtain all such authorizations or exemptions thereof, or consents thereto,
as may be necessary from any public regulatory body or bodies having
jurisdiction thereof.

                  If any Common Shares required to be reserved for issuance upon
exercise of Warrants require registration or qualification with any governmental
authority or other governmental approval or filing under any federal or state
law (otherwise than as provided in Section 9) before such shares may be so
issued, the Company will in good faith and as expeditiously as possible and at
its expense endeavor to cause such shares to be duly registered or such approval
to be obtained or filing made.

8.   TAKING OF RECORD; STOCK AND WARRANT TRANSFER BOOKS

                  In the case of all dividends or other distributions by the
Company to the holders of its Common Shares with respect to which any provision
of Section 4 refers to the taking of a record of such holders, the Company will
in each such case take such a record and will take such record as of the close
of business on a Business Day. The Company will not at any time, except upon
dissolution, liquidation or winding up of the Company, close its stock transfer
books or Warrant transfer books so as to result in preventing or delaying the
exercise or transfer of any Warrant.

9.   RESTRICTIONS ON TRANSFERABILITY; REGISTRATIONS

                  The Warrants and the Warrant Shares shall not be transferred,
hypothecated or assigned before satisfaction of the conditions specified in this
Section 9, which conditions are intended to ensure compliance with the
provisions of the Securities Act with respect to the Transfer of any Warrant or
any Warrant Share. Holder, by acceptance of this Warrant, agrees to be bound by
the provisions of this Section 9.

                  9.1. Restrictive Legend. (a) Except as otherwise provided in
this Section 9, each certificate for Warrant Shares initially issued upon the
exercise of this Warrant, and each certificate for Warrant Shares issued to any
subsequent transferee of any such certificate, shall be stamped or otherwise
imprinted with a legend in substantially the following form:

            "The shares represented by this certificate have not been
            registered under the Securities Act of 1933, as amended,
               and may not be transferred in violation of such Act
                    or the rules and regulations thereunder."

                  (b) Except as otherwise provided in this Section 9, each
Warrant shall be stamped or otherwise imprinted with a legend in substantially
the following form:

          "This warrant and the securities represented hereby have not
          been registered under the Securities Act of 1933, as amended,
              and may not be transferred in violation of such Act,
    the rules and regulations thereunder or the provisions of this Warrant."

                  9.2. Notice of Proposed Transfers; Requests for Registration.
Prior to any Transfer of any Warrant or any Restricted Common Share, the holder

<PAGE>

CUSIP NO. 00753C 10 2                 13D

of such Warrant or Restricted Common Share shall give written notice (a
"Transfer Notice") to the Company of such Transfer. Each certificate, if any,
evidencing such Restricted Common Share issued upon such Transfer shall bear the
restrictive legend set forth in Section 9.1(a), and each Warrant issued upon
such Transfer shall bear the restrictive legend set forth in Section 9.1(b),
unless in the opinion of counsel to such holder that is reasonably acceptable to
the Company such legend is not required in order to ensure compliance with the
Securities Act.

                  9.3. Registration. Each holder of Warrant Shares has certain
registration rights under the Registration Rights Agreement of even date
herewith between the Company and General Electric Company, as amended from time
to time. Any Holder may obtain a copy of such agreement by notice to the
Company.

10.  SUPPLYING INFORMATION

                  The Company shall cooperate with each Holder of a Warrant and
each holder of Restricted Common Shares in supplying such information as may be
reasonably necessary for such holder to complete and file any information
reporting forms presently or hereafter required by the Commission as a condition
to the availability of an exemption from the Securities Act for the sale of any
Warrant or Restricted Common Shares.

11.  LOSS OR MUTILATION

                  Upon receipt by the Company from any Holder of evidence
reasonably satisfactory to it of the ownership of and the loss, theft,
destruction or mutilation of this Warrant and indemnity reasonably satisfactory
to it (it being understood that the written agreement of GE shall be sufficient
indemnity), and in case of mutilation upon surrender and cancellation hereof,
the Company will execute and deliver in lieu hereof a new Warrant of like tenor
to such Holder; provided, in the case of mutilation, no indemnity shall be
required if this Warrant in identifiable form is surrendered to the Company for
cancellation.

12.  OFFICE OF THE COMPANY

                  As long as any of the Warrants remain outstanding, the Company
shall maintain an office or agency (which may be the principal executive offices
of the Company) where the Warrants may be presented for exercise, registration
of transfer, division or combination as provided in this Warrant.

13.  FINANCIAL AND BUSINESS INFORMATION

                  13.1. Quarterly Information. The Company will deliver to each
Holder, as soon as practicable after the end of each of the first three quarters
of the Company, and in any event within 45 days thereafter, one copy of an
unaudited consolidated balance sheet of the Company and its subsidiaries as at
the close of such quarter, and the related unaudited consolidated statements of
income and cash flows of the Company for such quarter and, in the case of the
second and third quarters, for the portion of the fiscal year ending with such
quarter, setting forth in each case in comparative form the figures for the
corresponding periods in the previous fiscal year. Such financial statements
shall be prepared by the Company in accordance with GAAP (without period-end
adjustments or footnotes) and accompanied by the certification of the Company's
chief executive officer or chief financial officer that such financial
statements are complete and correct and present fairly the consolidated
financial position, results of operations and cash flows of the Company and its
subsidiaries as at the end of such quarter and for such year-to-date period, as
the case may be.

<PAGE>

CUSIP NO. 00753C 10 2                 13D


                  13.2. Annual Information. The Company will deliver to each
Holder as soon as practicable after the end of each fiscal year of the Company,
and in any event within 90 days thereafter, one copy of:

                  (a) an audited consolidated balance sheet of the Company and
its subsidiaries as at the end of such year, and

                  (b) audited consolidated statements of income and cash flows
of the Company and its subsidiaries for such year;

setting forth in each case in comparative form the figures for the corresponding
periods in the previous fiscal year, all prepared in accordance with GAAP, and
which audited financial statements shall be accompanied by (i) an opinion
thereon of the independent certified public accountants regularly retained by
the Company, or any other firm of independent certified public accountants of
recognized national standing selected by the Company and (ii) a report of such
independent certified public accountants confirming any adjustment made pursuant
to Section 4 during such year.

                  13.3. Filings. The Company will file with the Commission all
regular or periodic reports required pursuant to the Exchange Act and will
deliver to Holder promptly upon their becoming available one copy of each
report, notice or proxy statement sent by the Company to its shareholders
generally, and of each regular or periodic report (pursuant to the Exchange
Act), filed by the Company with (i) the Commission or (ii) any securities
exchange on which Common Shares are listed.

14.  LIMITATION OF LIABILITY

                  No provision hereof, in the absence of affirmative action by
Holder to purchase Common Shares, and no enumeration herein of the rights or
privileges of Holder hereof, shall give rise to any liability of such Holder for
the purchase price of any Common Share or as a shareholder of the Company,
whether such liability is asserted by the Company or by creditors of the
Company.

15.  MISCELLANEOUS

                  15.1. Nonwaiver and Expenses. No course of dealing or any
delay or failure to exercise any right hereunder on the part of Holder shall
operate as a waiver of such right or otherwise prejudice Holder's rights, powers
or remedies. If the Company fails to comply with any provision of this Warrant,
the Company shall pay to Holder such amounts as shall be sufficient to cover any
costs and expenses including, but not limited to, reasonable attorneys' fees,
including those of appellate proceedings, incurred by Holder in enforcing any of
its rights, powers or remedies hereunder.

                  15.2. Notice Generally. Any notice, demand, request, consent,
approval, declaration, delivery or other communication hereunder to be made
pursuant to the provisions of this Warrant shall be sufficiently given or made
if in writing and either delivered in person with receipt acknowledged or sent
by registered or certified mail, return receipt requested, postage prepaid, or
by telecopy and confirmed by telecopy answerback, addressed as follows:

                  (a) If to any Holder or holder of Warrant Shares, at its last
known address appearing on the books of the Company maintained for such purpose.

<PAGE>

CUSIP NO. 00753C 10 2                 13D


                  (b)      If to the Company at

                           Advanced Lighting Technologies, Inc.
                           32000 Aurora Road
                           Solon, Ohio 44139
                           Attention: President
                           Telecopy Number: (440)519-0503

or at such other address as may be substituted by notice given as herein
provided. The giving of any notice required hereunder may be waived in writing
by the party entitled to receive such notice. Every notice, demand, request,
consent, approval, declaration, delivery or other communication hereunder shall
be deemed to have been duly given or served on the date on which personally
delivered, with receipt acknowledged, telecopied and confirmed by telecopy
answerback, one Business Day after the same shall have been delivered to a
nationally recognized courier service, or three Business Days after the same
shall have been deposited, postage prepaid, in the United States mail. Failure
or delay in receipt of copies of any notice, demand, request, approval,
declaration, delivery or other communication to the Person designated above
shall in no way adversely affect the effectiveness of such notice, demand,
request, approval, declaration, delivery or other communication.

                  15.3. Remedies. Each holder of a Warrant or a Warrant Share,
in addition to being entitled to exercise all rights granted by law, including
recovery of damages, will be entitled to specific performance of its rights
under Section 9 of this Warrant. The Company agrees that monetary damages would
not be adequate compensation for any loss incurred by reason of a breach by it
of the provisions of Section 9 of this Warrant and hereby agrees to waive the
defense in any action for specific performance that a remedy at law would be
adequate.

                  15.4. Successors and Assigns. Subject to the provisions of
Sections 3.1 and 9, this Warrant and the rights evidenced hereby shall inure to
the benefit of and be binding upon the successors of the Company and the
successors and assigns of Holder. The provisions of this Warrant are intended to
be for the benefit of all Holders from time to time of this Warrant and, with
respect to Section 9 hereof, holders of Warrant Shares, and shall be enforceable
by any such Holder or holder of Warrant Shares.

                  15.5. Amendment. This Warrant may be modified or amended or
the provisions hereof waived only with the written consent of the Company and
the Majority Holders; provided that no such Warrant may be modified or amended
to reduce the number of Common Shares for which such Warrant is exercisable or
to increase the price at which such Common Shares may be purchased upon exercise
of such Warrant (before giving effect to any adjustment as provided therein)
without the prior written consent of each Holder.

                  15.6. Severability. Wherever possible, each provision of this
Warrant shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Warrant shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Warrant.

                  15.7. Headings. The headings used in this Warrant are for the
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.

                  15.8. Governing Law. This Warrant shall be governed by the
laws of the State of New York, without regard to the provisions thereof relating
to conflict of laws.

CUSIP NO. 00753C 10 2                 13D


III. Liquidation, Dissolution or Winding Up.

         (a) Treatment at Liquidation, Dissolution or Winding Up. Upon any
liquidation, dissolution or winding up of the Corporation, whether voluntary or
involuntary, the holders of Series A Preferred Shares shall be entitled to
receive, prior and in preference to any distribution of any of the assets or
surplus funds of the Corporation to the holders of the Common Shares by reason
of their ownership thereof, the amount of $27.00 per Series A Preferred Share
(as adjusted for any stock dividends, combinations or splits with respect to
such shares), plus interest thereon calculated at a rate per annum equal to 8%

until the date of payment (the "Liquidation Preference Amount"). Interest shall
be determined on the basis of a 365 day year for the actual number of days
elapsed from the date of issuance until the date of payment. If upon the
occurrence of any liquidation, dissolution or winding up, the assets and surplus
funds required to be distributed among the Series A Preferred Shares shall be
insufficient to permit the payment to such holders of the full preferential
amount, then the entire assets and surplus funds of the Corporation legally
available for distribution shall be distributed among the holders of the Series
A Preferred Shares so that all holders of Series A Preferred Shares shall
receive an amount per share pro rata in accordance with the preferential amount
payable with respect to each Series A Preferred Share. After payment to the
holders of the Series A Preferred Shares of the amounts set forth above, the
entire remaining assets and funds of the Corporation legally available for
distribution, if any, shall be distributed among the holders of the Common
Shares in proportion to the Common Shares then held by them; provided, however,
that the holders of Series A Preferred Shares shall be entitled by reason of
their ownership thereof to participate in any such distribution of any remaining
assets or surplus funds to the holders of the Common Shares as if the holders of
the Series A Preferred Shares converted such securities into Common Shares at
the Conversion Ratio set forth in Subsection V below (as adjusted as set forth
herein) immediately prior to the date of such event in addition to receipt of
the amounts to which they are entitled on account of their ownership of the
Series A Preferred Shares as set forth above.

         (b) Treatment of Reorganizations, Consolidations, Mergers, and Sales of
Assets. For purposes of this Section III, any acquisition of the Corporation by
means of (i) consolidation, merger or other form of corporate reorganization in
which outstanding shares of the Corporation are exchanged for securities or
other consideration issued, or caused to be issued, by the acquiring corporation
or its subsidiary, or (ii) a sale of all or substantially all of the assets of
the Corporation, shall be treated as a liquidation, dissolution or winding up of
the Corporation and the holders of the Series A Preferred Shares, at their
option, shall have the right to receive, in lieu of the preferential
distributions described in this Section III, at the closing, the same
consideration per share payable to holders of the Common Shares as if the
holders of the Series A Preferred Shares converted such securities into Common
Shares at the Conversion Ratio set forth in Section V below (as adjusted as set
forth herein) immediately prior to the closing of such transaction.

         (c) Distributions Other than Cash. Whenever a distribution provided for
in this Section III shall be payable in securities or property other than cash,
the value of such distribution shall be the fair market value of such securities
or other property as determined in good faith by the Board of Directors.

IV. Voting.

         (a) General. In addition to special voting rights provided by
applicable law, each holder of Series A Preferred Shares shall be entitled to
vote on all matters and shall be entitled to cast four (4) votes for each Series
A Preferred Share held at the record date for the determination of shareholders
entitled to vote on such matter or, if no record date is established, at the
date such vote is taken or any written consent of shareholders is first
executed, such votes to be counted together with all other shares of capital
stock having general voting powers and not separately as a class.
Notwithstanding any adjustment to the Conversion Ratio (as defined in Section V)
pursuant to Section V, Section VI or Section VII hereof, no holder of Series A
Preferred Shares shall at any time be entitled to cast more than four (4) votes
for each Series A Preferred Share held by such holder. In all cases where the
holders of Series A Preferred Shares have the right to vote separately as a
class, such holders shall be entitled to one vote for each such share held by
them.

          (b) Special Meetings. The holders of at least a majority of the
aggregate number of Series A Preferred Shares then outstanding (evidenced in
writing by such holders or by vote at a meeting of shareholders called for such
purpose) shall have the right at any time to call for a special meeting of the
Board of Directors of the Corporation for such specified purposes as such
holders may deem desirable. Such special meeting shall be convened in accordance
with the applicable notice provisions of the Corporation's Code of Regulations.

V.   Conversion. The holders of Series A Preferred Shares shall have conversion
     rights as follows:

         (a) Optional Conversion; Fractional Shares. Each issued and outstanding
Series A Preferred Share shall be convertible, at the option of the holder
thereof, at any time and from time to time without the payment of additional
consideration, at the office of the Corporation or any transfer agent for such
stock, into 4 fully paid and nonassessable Common Shares (the "Conversion
Ratio"). The Corporation shall not be required to issue a fractional Common
Share upon conversion of any Series A Preferred Share. If any fraction of a
share would, but for this provision, be issuable upon conversion of a Series A
Preferred Share, in lieu of such fractional share, the Corporation may, at its
option, pay a cash adjustment in respect of such final fraction in an amount
equal to the same fraction of the Current Market Price per Common Share on the
date of conversion.

         (b) Reservation of Common Shares. The Corporation shall at all times
reserve and keep available out of its authorized but unissued Common Shares,
solely for the purpose of issuance upon the conversion of the Series A Preferred
Shares, such number of Common Shares issuable upon the conversion of all
outstanding Series A Preferred Shares. All Common Shares which are so issuable
shall, when issued, be duly and validly issued, fully paid and nonassessable and
free from all taxes, liens and charges. The Corporation shall take all such
actions as may be necessary to assure that all such Common Shares may be so
issued without violation of any applicable law or governmental regulation or any
requirements of any domestic securities exchange upon which Common Shares may be
listed (except for official notice of issuance which shall be immediately
delivered by the Corporation upon each such issuance).
         (c) Adjustments. Subject to NASDAQ Approval, the following adjustments
shall apply as set forth in this Section V. The Corporation shall give each
holder of Preferred Shares notice of any event described below in accordance
with Section V(d) below.

                      (i) Share Dividends, Subdivisions and Combinations. If at
any time the Corporation shall:

<PAGE>

CUSIP NO. 00753C 10 2                 13D

                      (A) take a record of the holders of its Common Shares for
the purpose of entitling them to receive a dividend payable in, or other
distribution of, Additional Common Shares,

                      (B) subdivide its outstanding Common Shares into a larger
number of Common Shares, or

                      (C) combine its outstanding Common Shares into a smaller
number of Common Shares,

  then, the Conversion Ratio shall be adjusted such that the number of Common
  Shares into which each Series A Preferred Share is convertible immediately
  after the occurrence of any such event shall be adjusted to equal the number
  of Common Shares that a record holder of the same number of Common Shares into
  which a Series A Preferred Share is convertible immediately prior to the
  occurrence of such event would own or be entitled to receive after the
  happening of such event.

                      (ii) Certain Other Distributions and Adjustments.

                      (A) If at any time the Corporation shall take a record of
the holders of its Common Shares for the purpose of entitling them to receive
any dividend or other distribution of:

                      (1) cash,

                      (2) any evidences of its indebtedness, any shares of its
stock or any other securities or property of any nature whatsoever (other than
cash, Convertible Securities or Additional Common Shares), or

                      (3) any warrants or other rights to subscribe for or
purchase any evidences of its indebtedness, any shares of its stock or any other
securities or property of any nature whatsoever (other than cash, Convertible
Securities or Additional Common Shares),

then, the holders of Series A Preferred Shares shall be entitled to receive such
dividend or distribution as if such holder had converted such Series A Preferred
Shares into Common Shares.

                      (B) A reclassification of the Common Shares (other than a
change in par value, or from par value to no par value or from no par value to
par value) into Common Shares and shares of any other class of stock shall be
deemed a distribution by the Corporation to the holders of its Common Shares of
such shares of such other class of stock within the meaning of Subsection
(c)(ii)(A) above and, if the outstanding Common Shares shall be changed into a
larger or smaller number of Common Shares as a part of such reclassification,
such change shall be deemed a subdivision or combination, as the case may be, of
the outstanding Common Shares within the meaning of Subsection (c)(i) hereof.

               (iii) Issuance of Additional Common Shares.

               (A) If at any time the Corporation shall (except as hereinafter
          provided) issue or sell any Additional Common Shares (an "Additional
          Issuance"), other than Permitted Issuances, in exchange for
          consideration in an amount per Additional Common Share less than
          either the Purchase Price or the Current Market Price on the date of

<PAGE>

CUSIP NO. 00753C 10 2                 13D

          such Additional Issuance (before giving effect to such Additional
          Issuance) then, effective at the time of such Additional Issuance, the
          number of Common Shares which will be issued upon conversion of the
          Series A Preferred Shares shall be increased to a number determined by
          multiplying the number of Common Shares subject to issuance upon
          conversion of the Series A Preferred Shares immediately before such
          Additional Issuance by a fraction, the numerator of which shall be the
          number of Common Shares immediately after giving effect to such
          Additional Issuance (calculated on a Fully Diluted Basis) and the
          denominator of which shall be the sum of: (1) the number of Common
          Shares outstanding immediately before giving effect to such Additional
          Issuance (calculated on a Fully Diluted Basis), plus

               (2) the number of Common Shares that the aggregate consideration
          received by the Corporation with respect to such Additional Issuance
          would purchase at the "Calculation Price" on the date of such
          Additional Issuance (before giving effect to such Additional
          Issuance).

For purposes of the preceding calculation, the term "Calculation Price" shall
mean (a) the Purchase Price if the consideration received per Additional Common
Share is less than the Purchase Price but greater than the Current Market Price,
(b) the Current Market Price if the consideration received per Additional Common
Share is less than the Current Market Price but greater than the Purchase Price
and (c) the greater of the Purchase Price and the Current Market Price if the
consideration received per Additional Common Share is less than both the
Purchase Price and the Current Market Price.

In computing adjustments under this Subsection, fractional interests in Common
Shares shall be taken into account to the nearest one-thousandth of a share.

               (B) Subsection (c)(iii)(A) shall not apply to any issuance of
          Additional Common Shares for which an adjustment is provided under
          Subsections (c)(i) and (c)(ii). No adjustment of the number of Common
          Shares into which the Series A Preferred Shares are convertible shall
          be made under Subsection (c)(iii)(A) upon the issuance of any
          Additional Common Shares that are issued pursuant to the exercise of
          any warrants or other subscription or purchase rights or pursuant to
          the exercise of any conversion or exchange rights in any Convertible
          Securities, if any such adjustment shall previously have been made
          upon the issuance of such warrants or other rights or upon the
          issuance of such Convertible Securities (or upon the issuance of any
          warrant or other rights therefor) pursuant to Subsections (c)(iv) and
          (c)(v).


                  (iv) Issuance of Warrants or Other Rights. If at any time the
Corporation shall take a record of the holders of its Common Shares for the
purpose of entitling them to receive a distribution of, or shall in any manner
(whether directly or by assumption in a merger in which the Corporation is the
surviving corporation) issue or sell, any warrants or other rights to subscribe
for or purchase any Additional Common Shares or any Convertible Securities,
whether or not the rights to exchange or convert thereunder are immediately
exercisable, and the price per share for which a Common Share is issuable upon

<PAGE>

CUSIP NO. 00753C 10 2                 13D

the exercise of such warrants or other rights or upon conversion or exchange of
such Convertible Securities shall be less than either the Purchase Price or the
Current Market Price on the date of such issue or sale, then the number of
Common Shares which will be issued upon conversion of the Series A Preferred
Shares shall be adjusted as provided in Subsection (c)(iii)(A) on the basis that
the maximum number of Additional Common Shares issuable pursuant to all such
warrants or other rights necessary to effect the conversion or exchange of all
such Convertible Securities shall be deemed to have been issued and outstanding
and the Corporation shall be deemed to have received all of the consideration
payable therefor, if any, as of the date of the issuance of such warrants or
other rights. No further adjustments to the number of Common Shares which will
be issued upon conversion of the Series A Preferred Shares shall be made upon
the actual issue of Common Shares or of Convertible Securities upon exercise of
warrants or other rights contemplated by this Subsection (c)(iv) or upon the
actual issue of Common Shares upon conversion or exchange of Convertible
Securities contemplated by this Subsection (c)(iv).

                  (v) Issuance of Convertible Securities. If at any time the
Corporation shall take a record of the holders of its Common Shares for the
purpose of entitling them to receive a distribution of, or shall in any manner
(whether directly or by assumption in a merger in which the Corporation is the
surviving corporation) issue or sell, any Convertible Securities, whether or not
the rights to exchange or convert thereunder are immediately exercisable, and
the price per share for which a Common Share is issuable upon such conversion or
exchange shall be less than either the Purchase Price or the Current Market
Price on the date of such issue or sale, then the number of Common Shares which
will be issued upon conversion of the Series A Preferred Shares shall be
adjusted as provided in Subsection (c)(iii)(A) on the basis that the maximum
number of Additional Common Shares necessary to effect the conversion or
exchange of all such Convertible Securities shall be deemed to have been issued
and outstanding and the Corporation shall have received all of the consideration
payable therefor, if any, as of the date of issuance of such Convertible
Securities. No adjustment to the number of Common Shares into which the Series A
Preferred Shares are convertible shall be made under this Subsection (c)(v) upon
the issuance of any Convertible Securities that are issued pursuant to the
exercise of any warrants or other subscription or purchase rights therefor, if
any such adjustment shall previously have been made upon the issuance of such
warrants or other rights pursuant to Subsection (c)(iv). No further adjustments
of the number of Common Shares into which the Series A Preferred Shares are
convertible shall be made upon the actual issue of such Common Shares upon
conversion or exchange of such Convertible Securities and, if any issue or sale
of such Convertible Securities is made upon exercise of any warrant or other
right to subscribe for or to purchase any such Convertible Securities for which
adjustments of the number of Common Shares into which the Series A Preferred
Shares are convertible have been or are to be made pursuant to other provisions
of this Subsection (c), no further adjustments of the number of Common Shares
into which the Preferred Shares are convertible shall be made by reason of such
issue or sale.

                  (vi) Superseding Adjustment. If, at any time after any
adjustment of the number of Common Shares into which the Series A Preferred
Shares are convertible shall have been made pursuant to Subsections (c)(iv) and
(c)(v) as the result of any issuance of warrants, rights or Convertible
Securities,

               (A) such warrants or rights, or the right of conversion or
          exchange in such other Convertible Securities, shall expire, and all
          or a portion of such warrants or rights, or the right of conversion or
          exchange with respect to all or a portion of such other Convertible
          Securities, as the case may be, shall not have been exercised, or

               (B) the consideration per share for which Common Shares are
          issuable pursuant to such warrants or rights, or the terms of such
          other Convertible Securities, shall be increased solely by virtue of

<PAGE>

CUSIP NO. 00753C 10 2                 13D

          provisions therein contained for an automatic increase in such
          consideration per share upon the occurrence of a specified date or
          event,

then the previous adjustment made to the number of Common Shares into which the
Preferred Shares are convertible shall be rescinded and annulled and the
Additional Common Shares that were deemed to have been issued by virtue of the
computation made in connection with the adjustment so rescinded and annulled
shall no longer be deemed to have been issued by virtue of such computation.
Thereupon, a recomputation shall be made of the effect of such rights or options
or other Convertible Securities on the basis of

               (C) treating the number of Additional Common Shares or other
          property, if any, theretofore actually issued or issuable pursuant to
          the previous exercise of any such warrants or rights or any such right
          of conversion or exchange, as having been issued on the date or dates
          of any such exercise and for the consideration actually received and
          receivable therefor, and

               (D) treating any such warrants or rights or any such other
          Convertible Securities that then remain outstanding as having been
          granted or issued immediately after the time of such increase of the
          consideration per share for which Common Shares or other property are
          issuable under such warrants or rights or other Convertible
          Securities; whereupon a new adjustment of the number of Common Shares
          into which the Series A Preferred Shares are convertible shall be
          made, which new adjustment shall supersede the previous adjustment so
          rescinded and annulled.

                      (vii) Other Provisions Applicable to Adjustments under
this Section. The following provisions shall be applicable to the making of
adjustments to the number of Common Shares into which the Series A Preferred
Shares are convertible provided for in this Subsection (c):

               (A) Computation of Consideration. To the extent that any
          Additional Common Shares or any Convertible Securities or any warrants
          or other rights to subscribe for or purchase any Additional Common
          Shares or any Convertible Securities shall be issued for cash
          consideration, the consideration received by the Corporation therefor
          shall be the amount of the cash received by the Corporation therefor,
          or, if such Additional Common Shares or Convertible Securities are
          offered by the Corporation for subscription, the subscription price,
          or, if such Additional Common Shares or Convertible Securities are
          sold to underwriters or dealers for public offering without a
          subscription offering, the initial public offering price (in any such
          case subtracting any amounts paid or receivable for accrued interest
          or accrued dividends and without taking into account any compensation,
          discounts or expenses paid or incurred by the Corporation for and in
          the underwriting of, or otherwise in connection with, the issuance
          thereof). To the extent that such issuance shall be for a
          consideration other than cash, then, except as herein otherwise
          expressly provided, the amount of such consideration shall be deemed
          to be the fair value of such consideration at the time of such
          issuance as determined in good faith by the Board of Directors of the
          Corporation. In case any Additional Common Shares or any Convertible
          Securities or any warrants or other rights to subscribe for or
          purchase such Additional Common Shares or Convertible Securities shall
          be issued in connection with any merger in which the Corporation
          issues any securities, the amount of consideration therefor shall be
          deemed to be the fair value, as determined in good faith by the Board
          of Directors of the Corporation, of such portion of the assets and

<PAGE>

CUSIP NO. 00753C 10 2                 13D

          business of the nonsurviving corporation as such Board in good faith
          shall determine to be attributable to such Additional Common Shares,
          Convertible Securities, warrants or other rights, as the case may be.
          The consideration for any Additional Common Shares issuable pursuant
          to any warrants or other rights to subscribe for or purchase the same
          shall be the consideration received by the Corporation for issuing
          such warrants or other rights plus the additional consideration
          payable to the Corporation upon exercise of such warrants or other
          rights. The consideration for any Additional Common Shares issuable
          pursuant to the term of any Convertible Securities shall be the
          consideration received by the Corporation for issuing warrants or
          other rights to subscribe for or purchase such Convertible Securities,
          plus the consideration paid or payable to the Corporation in respect
          of the subscription for or purchase of such Convertible Securities,
          plus the additional consideration, if any, payable to the Corporation
          upon the exercise of the right of conversion or exchange in such
          Convertible Securities. In case of the issuance at any time of any
          Additional Common Shares or Convertible Securities in payment or
          satisfaction of any dividends upon any class of stock other than
          Common Shares, the Corporation shall be deemed to have received for
          such Additional Common Shares or Convertible Securities a
          consideration equal to the amount of such dividend so paid or
          satisfied.

               (B) When Adjustments to Be Made. The adjustments required by this
          Subsection (c) shall be made whenever and as often as any specified
          event requiring an adjustment shall occur, except that any adjustment
          to the number of Common Shares into which the Series A Preferred
          Shares are convertible that would otherwise be required may be
          postponed (except in the case of a subdivision or combination of
          Common Shares, as provided for in Subsection (c)(i)) up to, but not
          beyond the date of conversion if such adjustment either by itself or
          with other adjustments not previously made adds or subtracts less than
          1% of the Common Shares into which the Series A Preferred Shares are
          convertible immediately prior to the making of such adjustment. Any
          adjustment representing a change of less than such minimum amount
          (except as aforesaid) that is postponed shall be carried forward and
          made as soon as such adjustment, together with other adjustments
          required by this Subsection (c) and not previously made, would result
          in a minimum adjustment or on the date of conversion. For the purpose
          of any adjustment, any specified event shall be deemed to have
          occurred at the close of business on the date of its occurrence.

               (C) Fractional Interests. In computing adjustments under this
          Subsection (c), fractional interests in Common Shares shall be taken
          into account to the nearest 1/1000th of a share.

               (D) When Adjustment Not Required. If the Corporation shall take a
          record of the holders of its Common Shares for the purpose of
          entitling them to receive a dividend or distribution or subscription
          or purchase rights and shall, thereafter and before the distribution
          to shareholders thereof, legally abandon its plan to pay or deliver
          such dividend, distribution, subscription or purchase rights, then
          thereafter no adjustment shall be required by reason of the taking of
          such record and any such adjustment previously made in respect thereof
          shall be rescinded and annulled.

               (E) Escrow of Shares. If after any property becomes distributable
          pursuant to this Subsection (c) by reason of the taking of any record
          of the holders of Common Shares, but prior to the occurrence of the
          event for which such record is taken, and the holders of Series A
          Preferred Shares convert such Series A Preferred Shares, any
          Additional Common Shares issuable upon exercise by reason of such
          adjustment shall be deemed the last Common Shares into which the
          Series A Preferred Shares have been converted (notwithstanding any
          other provision to the contrary herein) and such shares or other
          property shall be held in escrow for such holder by the Corporation to

<PAGE>

CUSIP NO. 00753C 10 2                 13D

          be issued to such holder upon and to the extent that the event
          actually takes place. Notwithstanding any other provision to the
          contrary herein, if the event for which such record was taken fails to
          occur or is rescinded, then such escrowed shares shall be cancelled by
          the Corporation and escrowed property returned to the Corporation.

               (F) Challenge to Good Faith Determination. Whenever the Board of
          Directors of the Corporation shall be required to make a determination
          in good faith of the fair value of any item under this Subsection (c),
          such determination may be challenged in good faith by the Majority
          Holders, and any dispute shall be resolved by an investment banking or
          valuation firm of recognized national standing selected by the
          Corporation and acceptable to the Majority Holders.

               (G) Prohibition on Adjustment. The provisions of Subsections
          (c)(iii), (c)(iv) and (c)(v) shall not operate to reduce the number of
          Common Shares which will be issued upon conversion of the Series A
          Preferred Shares.

                      (viii) Reorganization, Reclassification, Merger,
Consolidation or Disposition of Assets. In case the Corporation shall reorganize
its capital, reclassify its capital stock, consolidate or merge with or into
another corporation (where the Corporation is not the surviving corporation or
where there is a change in or distribution with respect to the Common Shares),
or sell, transfer or otherwise dispose of all or substantially all its property,
assets or business to another corporation and, pursuant to the terms of such
reorganization, reclassification, merger, consolidation or disposition of
assets, Common Shares of the successor or acquiring corporation, or any cash,
shares of stock or other securities or property of any nature whatsoever
(including warrants or other subscription or purchase rights) in addition to or
in lieu of common stock of the successor or acquiring corporation ("Other
Property"), are to be received by or distributed to the holders of Common Shares
of the Corporation, then each holder of Series A Preferred Shares shall have the
right thereafter to receive, upon conversion of such Series A Preferred Shares,
the number of Common Shares of the successor or acquiring corporation or of the
Corporation, if it is the surviving corporation, and Other Property receivable
upon or as a result of such reorganization, reclassification, merger,
consolidation or disposition of assets by a holder of the number of Common
Shares into which the Series A Preferred Shares owned by such holder are
convertible immediately prior to such event. In case of any such reorganization,
reclassification, merger, consolidation or disposition of assets, the successor
or acquiring corporation (if other than the Corporation) shall expressly assume
the due and punctual observance and performance of each and every covenant and
condition of the Series A Preferred Shares to be performed and observed by the
Corporation and all the obligations and liabilities hereunder, subject to such
modifications as may be deemed appropriate (as determined by resolution of the
Board of Directors of the Corporation) in order to provide for adjustments of
Common Shares into which the Series A Preferred Shares are convertible which
shall be as nearly equivalent as practicable to the adjustments provided for in
this Subsection (c). For purposes of this Subsection (c)(viii), "common stock of
the successor or acquiring corporation" shall include stock of such corporation
of any class that is not preferred as to dividends or assets over any other
class of stock of such corporation and that is not subject to redemption and
shall also include any evidences of indebtedness, shares of stock or other
securities that are convertible into or exchangeable for any such stock, either
immediately or upon the arrival of a specified date or the happening of a
specified event and any warrants or other rights to subscribe for or purchase
any such stock. The foregoing provisions of this Subsection (c)(viii) shall
similarly apply to successive reorganizations, reclassifications, mergers,
consolidations or disposition of assets.

                      (ix) Other Action Affecting Common Shares. In case at any
time or from time to time the Corporation shall take any action in respect of
its Common Shares, other than any action described in this Subsection (c), then,

<PAGE>

CUSIP NO. 00753C 10 2                 13D

unless such action will not have a materially adverse effect upon the rights of
holders of Series A Preferred Shares, the number of Common Shares or other stock
into which the Series A Preferred Shares are convertible shall be adjusted in
such manner as may be equitable in the circumstances.

                 (d) Notices to Holders of Series A Preferred Shares.

                      (i) Notice of Adjustments. Not less than 10 nor more than
30 days prior to the record date or effective date, as the case may be, of any
action that requires or might require an adjustment or readjustment pursuant to
Subsection (c), the Corporation shall forthwith prepare and deliver to each
holder of Series A Preferred Shares, a signed copy of a certificate executed by
the chief financial officer of the Corporation setting forth, in reasonable
detail, the event requiring the adjustment and the method by which such
adjustment was calculated (including a description of the basis on which the
Board of Directors of the Corporation determined the fair value of any evidences
of indebtedness, shares of stock, other securities or property or warrants or
other subscription or purchase rights referred to in Subsection (c)(vii)(A),
specifying the number of Common Shares into which the Series A Preferred Shares
are convertible and (if such adjustment was made pursuant to Subsections
(c)(viii) or (c)(ix)) describing the number and kind of any other shares of
stock or Other Property into which the Series A Preferred Shares are
convertible, after giving effect to such adjustment or change. The Corporation
shall keep at its office or agency copies of all such certificates and cause the
same to be available for inspection at said office during normal business hours
by any holder of Series A Preferred Shares or any prospective purchaser of
Series A Preferred Shares designated by a holder thereof.

                      (ii) Notice of Corporate Action. If at any time:

                         (A) the Corporation shall take a record of the holders
                    of its Common Shares for the purpose of entitling them to
                    receive a dividend or other distribution, or any right to
                    subscribe for or purchase any evidences of its indebtedness,
                    any shares of stock of any class or any other securities or
                    property, or to receive any other right, or

                         (B) there shall be any capital reorganization of the
                    Corporation, any reclassification or recapitalization of the
                    capital stock of the Corporation or any consolidation or
                    merger of the Corporation with, or any sale, transfer or
                    other disposition of all or substantially all the property,
                    assets or business of the Corporation to, another
                    corporation, person or entity, or

                         (C) there shall be a voluntary or involuntary
                    dissolution, liquidation or winding up of the Corporation;

then, in any one or more of such cases, the Corporation shall give to each
holder of Series A Preferred Shares (A) at least 30 days prior written notice of
the date on which a record date shall be selected for such dividend,
distribution or right or for determining rights to vote in respect of any such
reorganization, reclassification, merger, consolidation, sale, transfer,
disposition, dissolution, liquidation or winding up, and (B) in the case of any
such reorganization, reclassification, merger, consolidation, sale, transfer,
disposition, dissolution, liquidation or winding up, at least 30 days prior
written notice of the date when the same shall take place. Such notice in
accordance with the foregoing clause also shall specify (A) the date on which
any such record is to be taken for the purpose of such dividend, distribution or
right, the date on which the holders of Common Shares shall be entitled to any
such dividend, distribution or right, and the amount and character thereof, and
(B) the date on which any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, dissolution, liquidation or winding
up is to take place and the time, if any such time is to be fixed, as of which
the holders of Common Shares shall be entitled to exchange their Common Shares
for securities or other property deliverable upon such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up. Each such written notice shall be
sufficiently given if addressed to each holder of Series A Preferred Shares at
the last address of such holder appearing on the books of the Corporation.

VI. Redemption of Series A Preferred Shares.

         (a) Mandatory Redemption. The Corporation shall redeem all of the
issued and outstanding Series A Preferred Shares on September 30, 2010 (the
"Redemption Date"). The redemption price for the Series A Preferred Shares
redeemed shall be the Liquidation Preference Amount (the "Redemption Price"). If
on the Redemption Date the funds of the Corporation legally available are
insufficient to redeem all of the Series A Preferred Shares, the number of
Series A Preferred Shares legally permitted to be redeemed shall be redeemed and
Series A Preferred Shares which the Corporation is legally unable to redeem
shall be redeemed as soon thereafter as funds become legally available for such
redemption. In addition, with respect to any Series A Preferred Shares that the
Corporation is legally or otherwise unable to redeem within the one year period
commencing on the Redemption Date and, if the Conversion Ratio has not been
increased pursuant to Section VII, then, subject to NASDAQ Approval, the
Conversion Ratio applicable to such Series A Preferred Shares shall increase
from 4 Common Shares for each Series A Preferred Share to 8 Common Shares for
each Series A Preferred Share and the holders of the Series A Preferred Shares
shall have the right to convert such Series A Preferred Shares at any time prior
to redemption thereof by the Corporation.

         (b) Proration. To the extent the Corporation is legally unable to
redeem all Series A Preferred Shares on the Redemption Date, the Series A
Preferred Shares to be redeemed shall be selected pro rata in accordance with
the ratio the number of Series A Preferred Shares held by each respective holder
bears to the total number of Series A Preferred Shares then issued and
outstanding. Not less than 30 or more than 60 days' previous notice shall be
given to the holders of record of the Series A Preferred Shares to be redeemed,
by registered or certified mail, postage prepaid.

         (c) Mechanics. At least 60 days prior to the Redemption Date, written
notice (hereinafter referred to as the "Redemption Notice") shall be mailed,
postage prepaid, to each holder of record of the Series A Preferred Shares, at
its address shown on the records of the Corporation; provided, however, that the
Corporation's failure to give such Redemption Notice shall in no way affect its
obligation to redeem Series A Preferred Shares as provided in Section VI(a)
hereof. The Redemption Notice shall contain the following information:

                         (i) the number of Series A Preferred Shares held by the
                    holder and the total number of Series A Preferred Shares
                    held by all holders.

                         (ii) the Redemption Date and the applicable Redemption
                    Price;

                         (iii) the number of Series A Preferred Shares to be
                    redeemed; and

                         (iv) a statement that the holder is to surrender to the
                    Corporation, at the place designated herein, its certificate
                    or certificates representing the Series A Preferred Shares
                    to be redeemed.

         (d) Surrender of Certificates. Each holder of Series A Preferred Shares

VII. Put Options.

         (a) General Put Option. On September 30, 2004, the Majority Holders
shall have the right to require the Corporation to purchase all or part of the
Series A Preferred Shares that the Majority Holders then own at a purchase price
equal to the Put Option Purchase Price. If the Corporation fails to so purchase
any Put Shares under this Section VII(a) within any applicable Closing Period or
any applicable Subsequent Closing Period (each as defined in clause (f) below),
then, subject to NASDAQ Approval, the Conversion Ratio applicable to all
outstanding Series A Preferred Shares shall increase from 4 Common Shares for
each Series A Preferred Share to 8 Common Shares for each Series A Preferred
Share.

         (b) Opt Out/NASDAQ Put. If either (i) the Control Share Acquisition
Resolution is not approved by the affirmative vote of the holders of shares
entitling them to exercise a majority of the voting power of the Corporation at
the Corporation's 1999 annual meeting of shareholders, or (ii) NASDAQ Approval
is not obtained at the Corporation's 1999 annual meeting of shareholders, then
the Majority Holders shall have the right to require the Corporation to purchase
all or part of the Series A Preferred Shares that the Majority Holders then own
at a purchase price equal to the Put Option Purchase Price.

         (c) Governmental Approval Put. If within 365 days after the Original
Purchaser has filed its Notification and Report Form as required under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, in connection
with a Second Occurrence Failure by the Corporation under the Contingent Warrant
Agreement, the Corporation and the Original Purchaser are unable to obtain all
governmental and other approvals required under any applicable laws, statutes,
orders, rules, regulations or policies, or any guidelines promulgated
thereunder, including, without limitation, under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended ("Government Approval"), then the Majority
Holders shall have the right to require the Corporation to purchase all or part
of the Series A Preferred Shares that the Majority Holders then own at a
purchase price equal to the Put Option Purchase Price.

         (d) Occurrence Based Put. If the Corporation or any of its Subsidiaries
shall (i) authorize or issue any shares of capital stock of any class or any
options, warrants, or rights to purchase capital stock of any class or any
securities convertible into capital stock of any class, other than (A)
Conversion Shares issued upon conversion of the Series A Preferred Shares, (B)
Warrant Shares issued upon exercise of the Warrant, (C) Common Shares issued to
employees of the Corporation pursuant to the Stock Plans, (D) Contingent Shares
issued upon exercise of the Contingent Warrants, (E) capital stock of any
Subsidiary issued to the Corporation or any Subsidiary or (F) Common Shares
issued to satisfy obligations in respect of acquisitions of securities or assets
of any Person, provided that (I) such contracts were entered into prior to
September 30, 1999, and (II) the number of Common Shares subject to this
subparagraph (F) shall not exceed 110,000 in the aggregate, or (ii) directly or
indirectly sell, lease, or otherwise dispose of more than 10% of the properties
and assets of the Corporation and its Subsidiaries on a consolidated basis, in
the aggregate, to any Person (other than the Corporation any Subsidiary),
whether in one transaction or in a series of transactions over any period of
twelve consecutive months, or (iii) merge into or with or consolidate with any
other Person other than a Subsidiary, or (iv) create, incur, assume, or
otherwise become or remain liable, directly or indirectly, for any Indebtedness
for Borrowed Money that would cause the Corporation to have Indebtedness for
Borrowed Money in excess of $210,000,000 in the aggregate at any time, whether
by loan, guaranty, mortgage, or otherwise, excluding indebtedness incurred in
connection with a redemption of Series A Preferred Shares, then in any such case
the Majority Holders shall have the right to require the Corporation to purchase
all or part of the Series A Preferred Shares that the Majority Holders then own
at a purchase price equal to the Put Option Purchase Price. If the Corporation
fails to so purchase any Put Shares under this Section VII(d) within any
applicable Closing Period or any applicable Subsequent Closing Period, then,
subject to NASDAQ Approval, the Conversion Ratio applicable to all outstanding
Series A Preferred Shares shall increase from 4 Common Shares for each Series A
Preferred Share to 8 Common Shares for each Series A Preferred Share.

CUSIP NO. 00753C 10 2                 13D


         (e) Mechanics. The Corporation shall deliver written notice to each
holder of Series A Preferred Shares at such holder's address on the books and
records of the Corporation of each event giving rise to a Put Option under
clauses (b), (c) and (d) of this Section VII (the "Corporation Put Right
Notice"). The Corporation Put Right Notice shall be mailed by first class
certified mail, return receipt requested, no later than two (2) business days
after the occurrence of the event giving rise to the Put Option. In order to
exercise a Put Option under clause (b), (c) or (d) of this Section VII, a holder
of the Series A Preferred Shares shall, no later than ninety (90) days after
receipt of the Corporation Put Right Notice, send written notice to the
Corporation specifying that the holder has elected to exercise its Put Option.
In order to exercise a Put Option under clause (a) of this Section VII, a holder
of the Series A Preferred Shares shall, no later than September 30, 2004, send
written notice to the Corporation specifying that it has elected to exercise the
Put Option.

         (f) Closing Period. If the purchase or redemption of Put Shares under
clauses (a), (b), (c) or (d), as the case may be, would not cause or constitute
a default under any agreement or indenture relating to indebtedness of the
Corporation then outstanding (collectively, the "Credit Agreements"), the
closing of the purchase of Put Shares under this Section VII shall occur as soon
as practicable after the delivery of a Put Option Notice with respect to such
Put Shares on a date mutually acceptable to the Majority Holders and the
Corporation, but in no event later than one year from the date of delivery of
the applicable Put Option Notice (the "Closing Period"). If the Corporation may
purchase part but not all of the Put Shares without causing a default under the
Credit Agreements, the Corporation shall purchase, within the Closing Period,
that number of Put Shares (pro rata from each holder based on the number of Put
Shares held by each holder and the total number of Put Shares held by all
holders) that it may purchase without causing or constituting a default under
the Credit Agreements. Subject to any earlier conversion of any Put Shares, the
Corporation shall from time to time purchase Put Shares at any time that any
such purchase would not cause or constitute a default under the Credit
Agreements. The closing of the purchase of any Put Shares under the preceding
sentence shall occur as soon as practicable after the date that the
determination is made that such purchase will not cause or constitute a default
under the Credit Agreements on a date mutually acceptable to the Majority
Holders and the Corporation, but in no event later than sixty (60) days after
the date of such determination (each, a "Subsequent Closing Period"). Until
purchased by the Corporation in accordance with the terms of this Section VII,
the holders of the Put Shares shall have the right to convert Put Shares
notwithstanding delivery of a Put Option Notice.

         (g) Surrender of Certificates. Each holder of Put Shares to be
purchased pursuant to a Put Option shall surrender the certificate or
certificates representing all such Put Shares to the Corporation on or before
the closing of the purchase of the Put Shares, and thereupon the applicable Put
Option Purchase Price for such shares as set forth in this Section VII shall be
paid to the order of the person whose name appears on such certificate or
certificates for each Put Share purchased and each surrendered certificate shall
be cancelled and retired and new certificates representing any Series A
Preferred Shares not purchased shall be issued to the holder at no additional
cost. If any Put Shares are not purchased within the Closing Period or
Subsequent Closing Period, as the case may be, each certificate issued
representing such shares shall bear a legend indicating the increase, if any, in
the Conversion Ratio pursuant to this Section VII.

         (h) Certain Definitions. For purpose of this Section VII, the following
terms shall have the following meanings:

                  "Put Option" shall mean the option of the Majority Holders to
require the Corporation to purchase the Series A Preferred Shares owned by the
Majority Holders under clauses (a), (b), (c) and (d) of this Section VII.

respect to which the Majority Holders have elected to exercise their right to

Section VII.

VIII. No Reissuance of Preferred Stock. No Series A Preferred Share or Series A
Preferred Shares acquired by the Corporation by reason of redemption, purchase,
conversion or otherwise shall be reissued, and all such shares shall be
cancelled, retired and eliminated from the shares which the Corporation shall be
authorized to issue. The President or any Vice President and the Secretary or
any Assistant Secretary of the Corporation are hereby authorized and directed on
behalf of the Corporation to file such documents from time to time as may be

accordingly.

effective upon expiration of the waiting period under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976 applicable to the acquisition of an option
and a proxy in respect of the Hellman Option Shares and the Ruud Option Shares
pursuant to the Option Agreement, the Hellman Option Shares Proxy and the Ruud
Option Shares Proxy (the "Option Waiting Period") and from and after such date
Purchaser may exercise its rights under the Hellman Shares Proxy, including,
without limitation, its rights to vote the Net Hellman Shares; and

                              (ii) The Hellman Option Shares Proxy shall become
effective upon expiration of the Option Waiting Period and from and after such
date Purchaser may exercise its rights under the Hellman Option Shares Proxy,
including, without limitation, its rights to vote the Hellman Option Shares; and

                              (iii) The Ruud Option Shares Proxy shall become

including, without limitation, its rights to vote the Ruud Option Shares; and

                              (iv) Purchaser shall exercise the Warrant; and

terms of the Option Agreement, the form of which is attached hereto as Exhibit
F. The parties acknowledge and agree that in determining the number of Total

by Purchaser. The Option Agreement shall provide, among other things, that the
Options (as defined in the Option Agreement) may be exercised only after all
governmental and regulatory approvals (including, without limitation, any
approvals required under the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended) necessary in connection with Purchaser's ownership of a 25%
interest in the Company have been obtained and that the Option Period (as

issue to Purchaser a warrant in the form attached hereto as Exhibit 2.2(c) (the
"First Contingent Warrant") granting Purchaser the right to purchase, in
accordance with the terms set forth in such First Contingent Warrant and at the
Current Market Price (determined at the time the event giving rise to the
issuance of the First Contingent Warrant occurred), that number of additional
Common Shares necessary to give Purchaser a majority of the voting power of the
Company's capital stock (assuming for purposes of making such determination that
(A) Purchaser has fully exercised the Warrant, (B) Purchaser has not
transferred, or transferred the right to vote, any Warrant Shares, Preferred
Shares or Conversion Shares, and (C) Purchaser has the power and authority to
vote the Hellman Shares and the Ruud Shares). The First Contingent Warrant shall

Purchaser's receipt of the Accountant's Certificate indicating a Second
Occurrence Failure.

                       d. Except as provided in clause e. below and subject to

                              (i) The Ruud Shares Proxy shall become effective
(provided the Option Waiting Period has lapsed as of such date) and from and
after such date Purchaser may exercise its rights under the Ruud Shares Proxy,
including, without limitation, its rights to vote the Net Ruud Shares; and

                              (ii) The Excess Hellman Shares Proxy shall become
effective (provided the Option Waiting Period has lapsed as of such date) and
from and after such date Purchaser may exercise its rights under the Excess
Hellman Shares Proxy, including, without limitation, its rights to vote the
Excess Hellman Shares; and

                              (iii) Subject to NASDAQ Approval, the Company
shall issue to Purchaser a warrant (in addition to any First Contingent Warrant
issued to Purchaser in accordance with Section 2.2.c (vi) hereof) in the form
attached hereto as Exhibit 2.2(d) (the "Second Contingent Warrant") granting
Purchaser the right to purchase, in accordance with the terms set forth in such
Second Contingent Warrant and at the Current Market Price (determined at the
time the event giving rise to the issuance of the Second Contingent Warrant
occurred) that number of additional Common Shares necessary to give Purchaser a
majority of the voting power of the Company's capital stock (taking into account
the Hellman Shares and the Ruud Shares over which the Company has actual voting
control pursuant to the provisions of this Section 2.2 and assuming for the
purpose of making such determination that (A) Purchaser has fully exercised the
Warrant and (B) Purchaser has not transferred, or transferred the right to vote,
any Warrant Shares, Preferred Shares or Conversion Shares). The Second
Contingent Warrant shall be delivered to Purchaser no later than the third
Business Day following the Third Occurrence Failure.

                       e. If the EBITDA Ratio for any three consecutive fiscal
quarters immediately preceding a failure by the Company to meet the Required
Ratio for a Determination Period, other than the first Determination Period
ending December 31, 1999, is at least 2 to 1, then the failure to meet the
Required Ratio for such Determination Period (the "Most Recent Determination
Period") shall not be deemed to be a "Second Occurrence Failure" or a "Third
Occurrence Failure", as the case may be, for the purposes of this Section 2.2;
provided, however, that the EBITDA Ratio for the last full fiscal quarter
included in the Most Recent Determination Period will be the EBITDA Ratio for
the first full fiscal quarter included in the determination of the Required
Ratio for the Determination Period immediately succeeding the Most Recent
Determination Period.

                       f. The Company shall deliver to Purchaser (i) as soon as
practicable following, but in no event later than the 45th Business Day
following, the end of each fiscal quarter of the Company, commencing with the
fiscal quarter ending December 31, 1999, an "agreed upon procedures" letter of
the Company's independent certified public accountants in the form of Exhibit
2.2f(i) setting forth the calculation of the EBITDA Ratio (together with such
supporting information as Purchaser may reasonably request to verify the EBITDA
Ratio) for the most recently completed Determination Period, and (ii) as soon as
practicable following, but in no event later than the 90th Business Day
following the end of each fiscal year of the Company, commencing with the fiscal
year ending June 30, 2000, a certificate of the Company's independent certified
public accountants in the form of Exhibit 2.2f(ii) setting forth the calculation
of the EBITDA Ratio (together with such supporting information as Purchaser may
reasonably request to verify the EBITDA Ratio) for such fiscal year and for the
most recently completed Determination Period and certifying that such
calculations are true and correct (each such letter and certificate is referred
to as an "Accountant's Certificate").

                  2.3 Purchaser's Rights in the Event of Governmental
Proceeding. If any action or proceeding (a "Proceeding") before any Governmental
Body or agency is pending or threatened against the Company or any beneficial
owner of 5% or more of any class of equity securities of the Company (a "Company
Beneficial Owner"), including, without limitation, any Proceeding (i) seeking to

<PAGE>

CUSIP NO. 00753C 10 2                 13D

adjudicate the Company or any Company Beneficial Owner a bankrupt or insolvent
or seeking the appointment of a receiver, trustee, custodian or other similar
official for it, him or her or for any substantial part of its, his or her
assets, or (ii) in which the Company or any Company Beneficial Owner shall seek
protection or relief under any law relating to bankruptcy, insolvency, relief or
protection of debtors, and such Proceeding, directly or indirectly, prevents
Purchaser from exercising or realizing any of its rights under clauses c. or d.
of Section 2.2 of this Agreement, then, automatically and without further action
on the part of the Company or Purchaser, Purchaser shall be entitled to
simultaneously exercise or realize its rights under clauses c. and d. of Section
2.2 of this Agreement to the same extent as if there had occurred a Second
Occurrence Failure and a Third Occurrence Failure.

                                    SECTION 3

                   REPRESENTATIONS AND WARRANTIES OF PURCHASER

                  3.1 Investment. At the time of any Second Occurrence Failure
or a Third Occurrence Failure, and at the time of any exercise by Purchaser of
any of its purchase rights under the First Contingent Warrant or the Second
Contingent Warrant, Purchaser will be acquiring, respectively, the First
Contingent Warrant and the Second Contingent Warrant, and the Contingent Shares,
for investment for Purchaser's own account, not as a nominee or agent and not
with the view to, or for resale in connection with, any distribution thereof.
Purchaser understands that none of the Contingent Shares have been, nor will
they be (other than in accordance with the terms of the Registration Rights
Agreement referred to in Section 4.1(g)(ii) of the Stock Purchase Agreement),
registered under the Securities Act by reason of a specific exemption from the
registration provisions of the Securities Act that depends upon, among other
things, the bona fide nature of the investment intent and the accuracy of
Purchaser's representations as expressed herein.

                                    SECTION 4

                    CONDITIONS TO OBLIGATIONS OF THE COMPANY

respect to the exercise of any right, power, privilege, or remedy under this

Notwithstanding the foregoing, each party hereto shall have the right to waive

                  5.14 Right to Purchase. Except for Permitted Issuances, if at
any time after a Third Occurrence Failure the Company authorizes the issuance or
sale of any equity securities or securities containing options or rights to
acquire any shares of equity securities of the Company (any such securities or
debt, the "Offered Securities"), then, subject to NASDAQ Approval, the Company
shall first offer to sell the Offered Securities to Purchaser by written notice
to Purchaser (the "Company Notice"). Purchaser may elect to purchase Purchaser's
pro rata share (determined by the ratio of Purchaser's then existing holdings of
Common Shares and Common Share equivalents (including, without limitation,
Conversion Shares) to the total holdings of all shareholders of the Company on a
fully diluted basis (assuming exercise of the Warrant immediately prior to the
date of the applicable purchase in accordance with the terms of the Warrant) of
the Offered Securities at the price and on the terms specified in the Company
Notice by delivering written notice of such election to the Company within 20
days after delivery of the Company Notice. Upon the expiration of the offering
period described above, the Company shall be entitled to sell such of the
Offered Securities which the Purchaser has not elected to purchase during the 90
days following such expiration on terms and conditions no more favorable to the
purchasers thereof than those offered to the Purchaser. Any Offered Securities
offered or sold by the Company after such 90-day period must be reoffered to the
Purchaser pursuant to the terms of this Section 5.14. The rights of Purchaser
under this Section 5.14 shall terminate upon expiration of the term of this
Agreement as set forth in Section 5.13 hereof.

The time of determination of the Total Option Shares shall be the first Business
Day immediately following Purchaser's receipt of the Accountant's Certificate
indicating a Second Occurrence Failure.

                  Section 2.2. Grant of Ruud Option. Ruud does hereby grant to
Purchaser, or Purchaser's nominee, the exclusive and irrevocable right,
privilege and option (the "Ruud Option") to purchase at any time or from time to

securities into which the Ruud Option Shares hereafter may be converted. The
Hellman Option and the Ruud Option are hereinafter sometimes collectively
referred to as the "Options".

                  Section 2.3. Option Period. The Options are granted on the
date hereof and may be exercised by Purchaser from and after the date Purchaser
has received the Accountant's Certificate indicating a Second Occurrence Failure
and ending on the date that is the later of (i) the one (1) year anniversary of
the date of Purchaser's receipt of the Accountant's Certificate indicating a
Second Occurrence Failure, and (ii) the close of business on the 30th day
following receipt of all governmental and regulatory approvals (including,
without limitation, any approvals required under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended) necessary in connection with Purchaser's
ownership of a twenty-five percent (25%) interest in the Company (the "Option
Period").

                  Section 2.4. Purchase Price. The purchase price of the Hellman
Option Shares and the Ruud Option Shares shall be the Current Market Price of
such shares at the time of the Second Occurrence Failure.

                  Section 2.5. Exercise of the Options. Purchaser may exercise
the Options at any time during the Option Period by delivery to Hellman, with
respect to the exercise of the Hellman Option, and to Ruud, with respect to the
exercise of the Ruud Option, of written notice thereof at the notice address for
Hellman and Ruud, respectively, set forth in Section 4.4 hereof (an "Option
Notice"). The Hellman Option and the Ruud Option must both be exercised if
either is exercised. The closing (an "Option Closing") of the purchase and sale
of the Hellman Option Shares or the Ruud Option Shares, as the case may be,
shall occur as soon as practicable after the delivery of the Option Notice
pertaining to such shares but in no event later than ten (10) days from the date
of delivery of that Option Notice. The obligation of Purchaser to consummate the
purchase of any of the Hellman Option Shares or the Ruud Option Shares at any
Option Closing is conditioned upon the receipt by the Company and the
Shareholders of all governmental and regulatory approvals required for the
ownership of the Hellman Option Shares or the Ruud Option Shares, as the case
may be. At an Option Closing, certificates representing the Hellman Option
Shares or the Ruud Option Shares, as the case may be, shall be delivered,
together with stock powers duly executed in blank, to the Purchaser free and
clear of any and all claims, liens, charges, pledges or encumbrances and the
Purchaser shall deliver to Hellman and Ruud, as the case may be, their
respective allocable portion of the Option Purchase Price. Hellman and Ruud
shall pay any and all transfer and similar taxes imposed in connection with the
sale of the Hellman Option Shares and the Ruud Option Shares to Purchaser.

                  The Shareholders jointly and severally represent and warrant

as of September 30, 1999, is between Advanced Lighting Technologies, Inc., an
Ohio corporation (the "Company"), and General Electric Company, a New York

                                    RECITALS:

                  A. Pursuant to a Stock Purchase Agreement (the "Stock Purchase
Agreement") dated September 28, 1999, between the Company and the Purchaser, the
Purchaser has agreed to purchase seven hundred sixty-one thousand two hundred
fifty (761,250) shares of Series A Convertible Preferred Stock, par value $.001,
of the Company (the "Series A Shares")

                  B. It is a condition to the obligations of the Purchaser under
the Stock Purchase Agreement that the parties hereto execute this Agreement.

                  NOW, THEREFORE, in consideration of the foregoing and the
covenants contained herein, the parties agree as follows:

                  1. Definitions. Capitalized terms used but not otherwise

Commission.

                  "Common Shares" shall mean the common shares, par value $.001,

                  "Person" shall mean any natural person, corporation, firm,

of the Company issued or issuable with respect to the securities referred to in
clauses (i), (ii), (iii) or (iv) by way of a stock dividend or stock split or in
connection with a combination of shares, recapitalization, merger, consolidation
or other reorganization. As to any particular Registrable Securities, such
securities shall cease to be Registrable Securities when they have been
distributed to the public pursuant to an offering registered under the
Securities Act or sold to the public through a broker, dealer or market maker in
compliance with Rule 144 (or any similar rule then in force). For purposes of
this Agreement, a Person shall be deemed to be a holder of Registrable
Securities whenever the Person has the right to acquire, directly or indirectly,
the Registrable Securities (upon conversion or exercise in connection with a
transfer of securities or otherwise, but disregarding any restrictions or
limitations upon the exercise of such right), whether or not the acquisition has
actually been effected.

                  "Registration Expenses" shall have the meaning provided in
Section 6(a).

                  "Rule 144" shall mean Rule 144 promulgated under the

amended.

                  "Third Party Registrable Securities" shall mean securities

of Ruud Lighting, Inc., and the Registration Rights Agreement dated January 28,
1998, entered into in connection with the acquisition by the Company of
Deposition Sciences, Inc.

                  "Third Party Registration Rights" shall mean the registration
rights granted to the holders of the Third Party Registrable Securities.

                  "Warrant" shall mean the warrant in the form of Exhibit 1
attached to the Stock Purchase Agreement.

                  "1934 Act" shall mean the Securities Exchange Act of 1934, as
amended.

                  Other capitalized terms used herein shall have the meaning

                  2. Demand Registrations.

                  (a) Requests for Registration. Subject to the terms and
conditions hereof, if the holders of Registrable Securities representing at
least either (i) an aggregate of 30% of the total of all Registrable Securities,
or (ii) Registrable Securities having a minimum anticipated aggregate offering
price of at least $7,500,000, request registration under the Securities Act of
any of their Registrable Securities on Form S-1 or any similar long-form
registration ("Long-Form Registrations") or, as provided in Section 2(c), the
holders of Registrable Securities request registration under the Securities Act
of all or part of their Registrable Securities on Form S-2 or S-3 or any similar
short-form registration ("Short-Form Registrations"), if available, which
requests specify the approximate number of Registrable Securities requested to
be registered and the anticipated per share price range for such offering, then
within ten days after receipt of any such request, the Company shall give

<PAGE>

CUSIP NO. 00753C 10 2                 13D

written notice of such requested registration to all other holders of
Registrable Securities and shall include in the registration all Registrable
Securities with respect to which the Company has received written requests for
inclusion therein within 15 days after the receipt of the Company's notice. All
registrations requested pursuant to this Section 2(a) are referred to herein as
"Demand Registrations."

                  (b) Long-Form Registrations. The holders of Registrable
Securities shall be entitled to request one (1) Long-Form Registration in which
the Company shall pay all Registration Expenses ("Company-paid Long-Form
Registrations"). A registration shall not count as the one (1) permitted
Long-Form Registration until it has become effective, and any Company-paid
Long-Form Registration above shall not count as the one (1) permitted Long-Form
Registration unless the holders of Registrable Securities are able to register
and sell 100% of the Registrable Securities requested to be included in such
registration. Notwithstanding the foregoing, the Company shall pay all
Registration Expenses in connection with any registration initiated as a
Company-paid Long-Form Registration, whether or not it has become effective;
provided, however, that the Company shall not be required to pay the
Registration Expenses of a Long-Form Registration which is withdrawn at the
request of the holders of Registrable Securities participating in such offering.

                  (c) Short-Form Registrations. In addition to the Long-Form
Registration provided pursuant to Section 2(b), the holders of Registrable
Securities shall be entitled to request an unlimited number of Short-Form
Registrations, each with a minimum anticipated aggregate offering price of at
least $1,500,000 in which the Company shall pay all Registration Expenses.
Demand Registrations shall be Short-Form Registrations whenever the Company is
permitted to use any applicable short form. After the Company has become subject
to the reporting requirements of the 1934 Act, the Company shall use its best
efforts to make Short-Form Registrations available for the sale of Registrable
Securities.

                  (d) Priority on Demand Registrations. Except as required by
the Third Party Registration Rights, the Company shall not include in any Demand
Registration any securities which are not Registrable Securities without the
prior written consent of the holders of a majority of the Registrable Securities
initially requesting such registration. If a Demand Registration is an
underwritten offering and the managing underwriters advise the Company in
writing that in their opinion the number of Registrable Securities and, if
permitted hereunder, other securities requested to be included in such offering
exceeds the number of Registrable Securities and other securities, if any, which
can be sold in an orderly manner in such offering within a price range
acceptable to the holders of a majority of the Registrable Securities initially
requesting registration, the Company shall include in the registration, prior to
the inclusion of any securities which are not Registrable Securities, the number
of Registrable Securities requested to be included which, in the opinion of the
underwriters, can be sold in an orderly manner within the price range of the
offering, pro rata among the respective holders thereof on the basis of the
amount of Registrable Securities owned by each such holder. Any Persons other
than holders of Registrable Securities who participate in Demand Registrations
which are not at the Company's expense must pay their share of the Registration
Expenses as provided in Section 7.

                  (e) Restrictions on Registrations. The Company shall not be
obligated to effect any Demand Registration within six months after the
effective date of a previous Demand Registration or a registration in which the
holders of Registrable Securities were given piggyback rights pursuant to
Section 3 and in which there was no reduction in the number of Registrable

<PAGE>

CUSIP NO. 00753C 10 2                 13D

Securities requested to be included (except to the extent permitted pursuant to
Section 2(b) with respect to a Long-Form Registration). The Company may postpone
for up to six months the filing or the effectiveness of a registration statement
for a Demand Registration if the Board of Directors of the Company determines in
good faith that it is reasonably foreseeable that the Demand Registration would
reasonably be expected to have a material adverse effect on any proposal or plan
by the Company to engage in any acquisition of assets (other than in the
ordinary course of business) or any merger, consolidation, tender offer or
similar transaction; provided, that, in such event, the holders of Registrable
Securities initially requesting the Demand Registration shall be entitled to
withdraw such request and, if such request is withdrawn, the Demand Registration
shall not count as the one (1) permitted Long-Form Registration hereunder, and
the Company shall pay all Registration Expenses in connection with the withdrawn
registration.

                  (f) Selection of Underwriters. The holders of a majority of
the Registrable Securities initially requesting registration shall have the
right to select the investment banker(s) and manager(s) to administer the
offering, subject to the Company's approval which shall not be unreasonably
withheld.

                  3. Piggyback Registrations.

                  (a) Right to Piggyback. Subject to the terms and conditions
hereof, whenever the Company proposes to register any of its securities under
the Securities Act (other than pursuant to a Demand Registration) and the
registration form to be used may be used for the registration of Registrable
Securities (a "Piggyback Registration"), the Company shall give prompt written
notice to all holders of Registrable Securities of the Company's intention to
effect such a registration and shall include in the registration all Registrable
Securities with respect to which the Company has received written requests for
inclusion therein within 15 days after the receipt of the Company's notice.

                  (b) Piggyback Expenses. The Registration Expenses of the
holders of Registrable Securities shall be paid by the Company in all Piggyback
Registrations.

                  (c) Priority on Primary Registrations. If a Piggyback
Registration is an underwritten primary registration on behalf of the Company
and the managing underwriters advise the Company in writing that in their
opinion the number of securities requested to be included in such registration
exceeds the number which can be sold in an orderly manner in such offering
within a price range acceptable to the Company, subject to the Third Party
Registration Rights, the Company shall include in such registration (i) first,
the securities the Company proposes to sell, (ii) second, the Registrable
Securities requested to be included in the registration, pro rata among the
holders of such Registrable Securities on the basis of the number of shares
owned by each such holder, and (iii) third, other securities requested to be
included in the registration.

                  (d) Priority on Secondary Registrations. If a Piggyback
Registration is an underwritten secondary registration on behalf of holders of
the Company's securities and the managing underwriters advise the Company in
writing that, in their opinion, the number of securities requested to be
included in the registration exceeds the number which can be sold in an orderly
manner in such offering within a price range acceptable to the holders initially
requesting the registration, subject to the Third Party Registration Rights, the

<PAGE>

CUSIP NO. 00753C 10 2                 13D

Company shall include in such registration (i) first, the Registrable Securities
requested to be included in the registration, pro rata among the holders of such
Registrable Securities on the basis of the number of shares owned by each
holder, and (ii) second, other securities requested to be included in such
registration.

                  (e) Selection of Underwriters. If any Piggyback Registration
is an underwritten offering, the selection of investment banker(s) and
manager(s) for the offering must be approved by the holders of a majority of the
Registrable Securities included in such Piggyback Registration, which approval
shall not be unreasonably withheld.

                  (f) Other Registrations. If the Company has previously filed a
registration statement with respect to Registrable Securities (pursuant to
Section 2 or pursuant to this Section 3), and if such previous registration has
not been withdrawn or abandoned, the Company shall not file or cause to be
effected any other registration of any of its equity securities or securities
convertible or exchangeable into or exercisable for its equity securities under
the Securities Act (except on Form S-8 or any successor form), whether on its
own behalf or at the request of any holder or holders of such securities, until
a period of at least six months has elapsed from the effective date of the
previous registration.

                  4. Holdback Agreements.

                  (a) Each holder of Registrable Securities agrees not to effect
any public sale or distribution (including sales pursuant to Rule 144) of equity
securities of the Company, or any securities convertible into or exchangeable or
exercisable for such securities, during the seven days prior to and the 90-day
period or such longer period as required by the underwriters managing the
registered public offering beginning on the effective date of any underwritten
Demand Registration or underwritten Piggyback Registration in which Registrable
Securities are included (except for sales of such securities as part of such
underwritten registered offering and as otherwise permitted under Rule 144(k)),
unless the underwriters managing the registered public offering otherwise agree.

                  (b) The Company agrees (i) not to effect any public sale or
distribution of its equity securities, or any securities convertible into or
exchangeable or exercisable for such securities, during the seven days prior to
and during the 90-day period or such longer period as required by the
underwriters managing the registered public offering beginning on the effective
date of any underwritten Demand Registration or any underwritten Piggyback
Registration (except as part of such underwritten registration or pursuant to
registrations on Form S-8 or any successor form), unless the underwriters
managing the registered public offering otherwise agree, and (ii) to cause each
holder of its equity securities, or any securities convertible into or
exchangeable or exercisable for its equity securities, purchased from the
Company at any time after the date of this Agreement (other than in a registered
public offering) to agree not to effect any public sale or distribution
(including sales pursuant to Rule 144) of any such securities during such period
(except as part of such underwritten registration, if otherwise permitted),
unless the underwriters managing the registered public offering otherwise agree.

                  5. Registration Procedures. Whenever the holders of
Registrable Securities have requested that any Registrable Securities be
registered pursuant to this Agreement, the Company shall use its best efforts to
effect the registration and the sale of such Registrable Securities in
accordance with the intended method of disposition thereof, and pursuant thereto
the Company shall as expeditiously as possible:

of the registration statement; provided that before filing a registration
statement or prospectus or any amendments or supplements thereto, the Company
shall furnish to the counsel selected by the holders of a majority of the
Registrable Securities covered by the registration statement copies of all such
documents proposed to be filed, including documents that are to be incorporated
by reference into the registration statement, amendment or supplement, which
documents shall be subject to the review of such counsel, and which proposed
registration statement or amendment or supplement thereto shall not be filed by
the Company if the holders of a majority of the Registrable Securities covered
by the registration statement, amendment or supplement reasonably object to such
filing;

                  (b) Prepare and file with the Commission such amendments and
supplements to the registration statement and the prospectus used in connection

owned by such holder;

                  (d) Use its best efforts to register or qualify such

Securities owned by such holder;

                  (e) Notify each holder of such Registrable Securities, at any
time when a prospectus relating thereto is required to be delivered under the
Securities Act, of the happening of any event as a result of which the
prospectus included in such registration statement contains an untrue statement
of a material fact or omits any fact necessary to make the statements therein
not misleading, and, at the request of any such holder, the Company shall
prepare a supplement or amendment to the prospectus so that, as thereafter
delivered to the purchasers of such Registrable Securities, such prospectus
shall not contain an untrue statement of a material fact or omit to state any
fact necessary to make the statements therein not misleading;

                  (f) Promptly notify the holders of Registrable Securities and
the underwriters, if any, of the following events and (if requested by any such
Persons) confirm such notification in writing: (i) the filing of the prospectus

system and, if listed on the NASD automated quotation system, endeavor to secure
designation of all such Registrable Securities covered by the registration
statement as a NASDAQ "national market system security" within the meaning of
Rule 11Aa2-1 of the Commission or, failing that, to secure NASDAQ authorization
for such Registrable Securities and, without limiting the generality of the
foregoing, to arrange for at least two market makers to register as such with
respect to such Registrable Securities with the NASD;

                  (h) Provide a transfer agent and registrar for all such
Registrable Securities not later than the effective date of such registration
statement;

                  (i) Enter into such customary agreements (including, without

effecting a stock split or a combination of shares);

                  (j) Make available for inspection by any holder of Registrable
Securities, any underwriter participating in any disposition pursuant to the

officers, directors, employees and independent accountants to supply all
information reasonably requested by any such holder, underwriter, attorney,
accountant or agent in connection with the registration statement;

                  (k) Otherwise endeavor to comply with all applicable rules and
regulations of the Commission, and make available to its security holders, as
soon as reasonably practicable, an earnings statement covering the period of at
least twelve months beginning with the first day of the Company's first full
calendar quarter after the effective date of the registration statement, which
earnings statement shall satisfy the provisions of Section 11(a) of the
Securities Act and Rule 158 thereunder;

                  (l) Permit any holder of Registrable Securities to participate
in the preparation of such registration or comparable statement and to require
the insertion therein of material furnished to the Company in writing, which in
the reasonable judgment of the holder and its counsel should be included;

                  (m) Make every reasonable effort to prevent the entry of any
order suspending the effectiveness of the registration statement and, in the
event of the issuance of any such stop order, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any security included in such registration statement for sale in any
jurisdiction, the Company shall use its best efforts promptly to obtain the

least two business days prior to any delivery of Registrable Securities to the
underwriters;

                  (p) Provide a CUSIP number for all Registrable Securities not

and any post-effective amendment thereto and at each closing of an underwritten
offering, (i) make such representations and warranties to the selling holders of
such Registrable Securities and the underwriters, if any, with respect to the
Registrable Securities and the registration statement as are customarily made by
issuers to underwriters in primary underwritten offerings, (ii) obtain opinions
of counsel to the Company and updates thereof (which counsel and which opinions

of a majority of the Registrable Securities being sold) addressed to each
selling holder and the underwriters, if any, covering the matters customarily
covered in opinions requested in underwritten offerings and such other matters
as may be reasonably requested by such holders and underwriters or their
counsel, (iii) obtain "cold comfort" letters and updates thereof from the

requested by the holders of a majority of the Registrable Securities being sold

CUSIP NO. 00753C 10 2                 13D

                  6. Registration Expenses.

                  (a) All expenses incident to the Company's performance of or
compliance with this Agreement, including without limitation all registration
and filing fees, fees and expenses of compliance with securities or blue sky
laws, printing expenses, messenger and delivery expenses, and fees and
disbursements of counsel for the Company and all independent certified public
accountants, underwriters (excluding discounts and commissions) and other
Persons retained by the Company (all such expenses being herein called
"Registration Expenses"), shall be borne by the Company, and the Company shall
pay its internal expenses (including, without limitation, all salaries and
expenses of its officers and employees performing legal or accounting duties),
the expense of any annual audit or quarterly review, the expense of any
liability insurance and the expenses and fees for listing the securities to be
registered on each securities exchange on which similar securities issued by the
Company are then listed or on the NASD automated quotation system.

                  (b) In connection with each Demand Registration and each
Piggyback Registration, the Company shall reimburse the holders of Registrable
Securities covered by such registration for the reasonable fees and
disbursements of one (1) counsel chosen by the holders of a majority of the
Registrable Securities initially requesting such registration.

                  (c) To the extent Registration Expenses are not required to be
paid by the Company, each holder of securities included in any registration
hereunder shall pay those Registration Expenses allocable to the registration of
the holder's securities so included, and any Registration Expenses not so
allocable shall be borne by all sellers of securities included in the
registration in proportion to the aggregate selling price of the securities to
be so registered.

                  7. Indemnification.

                  (a) The Company agrees to indemnify, to the extent permitted
by law, each holder of Registrable Securities, its affiliates and their
respective officers, directors, employees and agents, as the case may be, and
each Person who controls the holder (within the meaning of the Securities Act),
against all losses, claims, damages, liabilities and expenses caused by any
untrue or alleged untrue statement of material fact contained in any
registration statement, prospectus or preliminary prospectus or any amendment
thereof or supplement thereto or any omission or alleged omission of a material
fact required to be stated therein or necessary to make the statements therein
not misleading, except insofar as the same are caused by or contained in any
information furnished in writing to the Company by such holder expressly for use
therein as provided in Section 7(b) below. In connection with an underwritten
offering, the Company shall indemnify the underwriters, their officers,
directors and partners, as the case may be, and each Person who controls the
underwriters (within the meaning of the Securities Act), to the same extent as
provided above with respect to the indemnification of the holders of Registrable
Securities.

                  (b) In connection with any registration statement in which a
holder of Registrable Securities is participating, each holder shall furnish to
the Company in writing such information and affidavits as the Company reasonably
requests for use in connection with any such registration statement or
prospectus and, to the extent permitted by law, shall indemnify the Company, its
directors and officers and each Person who controls the Company (within the
meaning of the Securities Act) against any losses, claims, damages, liabilities
and expenses resulting from any untrue or alleged untrue statement of material

<PAGE>

CUSIP NO. 00753C 10 2                 13D

fact contained in the registration statement, prospectus or preliminary
prospectus or any amendment thereof or supplement thereto or any omission or
alleged omission of a material fact required to be stated therein or necessary
to make the statements therein not misleading, but only to the extent that such
untrue statement or omission is contained in any information or affidavit so
furnished in writing by the holder; provided that the obligation to indemnify
shall be individual to each holder and shall be limited to the net amount of
proceeds received by the holder from the sale of Registrable Securities pursuant
to the registration statement.

                  (c) Any Person entitled to indemnification hereunder shall (i)
give prompt written notice to the indemnifying party of any claim with respect
to which it seeks indemnification and (ii) unless in the indemnified party's
reasonable judgment a conflict of interest between the indemnified and the
indemnifying parties may exist with respect to such claim, permit the
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. If such defense is assumed, the
indemnifying party shall not be subject to any liability for any settlement made
by the indemnified party without its consent (but such consent shall not be
unreasonably withheld). An indemnifying party who is not entitled to, or elects
not to, assume the defense of a claim shall not be obligated to pay the fees and
expenses of more than One (1) counsel for all parties indemnified by the
indemnifying party with respect to such claim, unless in the reasonable judgment
of any indemnified party, a conflict of interest may exist between the
indemnified party and any other of such indemnified parties with respect to such
claim.

                  (d) The indemnification provided for under this Agreement
shall remain in full force and effect regardless of any investigation made by or
on behalf of the indemnified party or any officer, director or controlling
Person of such indemnified party and shall survive the transfer of securities.
The Company also agrees to make such provisions as are reasonably requested by
any indemnified party for contribution to the party in the event the Company's
indemnification is unavailable for any reason.

                  8. Participation in Underwritten Registrations. No Person may
participate in any registration hereunder which is underwritten unless the
Person (a) agrees to sell the Person's securities on the basis provided in any
underwriting arrangements approved by the Person or Persons entitled hereunder
to approve such arrangements, and (b) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
required under the terms of such underwriting arrangements; provided that no
holder of Registrable Securities included in any underwritten registration shall
be required to make any representations or warranties to the Company or the
underwriters other than representations and warranties regarding the holder and
the holder's intended method of distribution.

                  9. Reports Under the Securities Laws. With a view to making
available to the holders of Registrable Securities the benefits of Rule 144 and
any other rule or regulation of the Commission that may at any time permit the
holder to sell securities of the Company to the public without registration, the
Company agrees to use its best efforts to:

                  (a) Make and keep public information available, as those terms
are understood and defined in Rule 144, at all times subsequent to 90 days after
the effective date of any registration statement covering an underwritten public
offering filed under the Securities Act by the Company;

<PAGE>

CUSIP NO. 00753C 10 2                 13D

                  (b) File with the Commission in a timely manner all reports
and other documents required of the Company under the Securities Act and the
1934 Act at any time after it is subject to the registration requirements; and

                  (c) Furnish to any the holder so long as the holder owns any
of the Registrable Securities forthwith upon request a written statement by the
Company that it has complied with the reporting requirements of Rule 144 (at any
time after 90 days after the effective date of the registration statement filed
by the Company), and of the Securities Act and the 1934 Act (at any time after
it has become subject to such reporting requirements), a copy of the most recent
annual or quarterly report of the Company, and such other reports and documents
so filed by the Company as may be reasonably requested by any holder in availing
itself of any rule or regulation of the Commission permitting the selling of any
the securities without registration.

                  10. Certain Limitations in Connection with Future Grants of
Registration Rights. From and after the date of this Agreement, the Company
shall not enter into any agreement with any holder or prospective holder of any
securities of the Company providing for the granting to the holder of
registration rights unless the agreement:

                  (a) Includes as a term the equivalent of Section 4 of this
Agreement;

                  (b) Includes a provision that, in the case of a Demand
Registration, protects the holders of Registrable Securities if marketing
factors require a limitation on the number of securities to be included in an
underwriting in the manner contemplated by Sections 2(d), 3(c) and 3(d) of this
Agreement;

                  (c) Is otherwise not inconsistent with the rights granted to
the holders of Registrable Securities in this Agreement; and

                  (d) Is approved by the holders of a majority of the
Registrable Securities then outstanding.

                  11. Transfer of Registration Rights. Provided that the Company
is given written notice by the holder of Registrable Securities at the time of
any transfer of Registrable Securities by such holder stating the name and
address of the transferee of such Registrable Securities and identifying the
securities with respect to which the rights under this Agreement are being
assigned, the rights of the holder of Registrable Securities under this
Agreement may be transferred in whole or in part at any time to any such
transferee, so long as such transfer of securities is in accordance with all
applicable state and federal securities laws and regulations.

                  12. Miscellaneous.

                  (a) No Inconsistent Agreements. The Company shall not
hereafter enter into any agreement with respect to its securities which is
inconsistent with or violates the rights granted to the holders of Registrable
Securities in this Agreement.

                  (b) Adjustments Affecting Registrable Securities. The Company
shall not take any action, or permit any change to occur, with respect to its
securities which would materially and adversely affect the ability of the
holders of Registrable Securities to include such Registrable Securities in a
registration undertaken pursuant to this Agreement or which would materially and

<PAGE>

CUSIP NO. 00753C 10 2                 13D

adversely affect the marketability of such Registrable Securities in any such
registration (including, without limitation, effecting a stock split or a
combination of shares).

                  (c) Remedies. Any Person having rights under any provision of
this Agreement shall be entitled to enforce such rights specifically to recover
damages caused by reason of any breach of any provision of this Agreement and to
exercise all other rights granted by law. The parties hereto agree and
acknowledge that money damages may not be an adequate remedy for any breach of
the provisions of this Agreement and that any party may, in its sole discretion,
apply to any court of law or equity of competent jurisdiction (without posting
any bond or other security) for specific performance and for other injunctive
relief in order to enforce or prevent violation of the provisions of this
Agreement.

                  (d) Amendments and Waivers. Except as otherwise provided
herein, the provisions of this Agreement may be amended or waived only upon the
prior written consent of the Company and holders of a majority of the
Registrable Securities (excluding all Registrable Securities held by the
Company). The failure of any party to enforce any of the provisions of this
Agreement will in no way be construed as a waiver of such provisions and will
not affect the right of such party thereafter to enforce each and every
provision of this Agreement in accordance with its terms.

                  (e) Successors and Assigns. All covenants and agreements in
this Agreement by or on behalf of any of the parties hereto shall bind and inure
to the benefit of the respective successors and assigns of the parties hereto,
whether so expressed or not. In addition, whether or not any express assignment
has been made, the provisions of this Agreement which are for the benefit of
purchasers or holders of Registrable Securities are also for the benefit of, and
enforceable by, any subsequent holder of Registrable Securities who consents in
writing to be bound by this Agreement.

                  (f) Severability. Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be prohibited
by or invalid under applicable law, that provision shall be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of this Agreement.

                  (g) Counterparts. This Agreement may be executed
simultaneously in multiple counterparts, any one of which need not contain the
signatures of more than one party, but all such counterparts taken together
shall constitute one and the same Agreement.

                  (h) Descriptive Headings; Interpretation. The descriptive
headings of this Agreement are inserted for convenience only and do not
constitute a Section of this Agreement. The use of the word "including" in this
Agreement shall be by way of example rather than by limitation.

                  (i) Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York, without regard
to principles of conflicts of law.

                                                                       Exhibit E
                  RIGHT OF FIRST REFUSAL AND CO-SALE AGREEMENT


                  This Right of First Refusal and Co-Sale Agreement (this
"Agreement") is made and entered into as of September 30, 1999, by and among
Wayne R. Hellman ("Hellman"), Hellman, Ltd., an Ohio limited liability company
("Hellman Ltd."), Alan J. Rudd ("Ruud") and General Electric Company, a New York
corporation ("GE").

                                    RECITALS:

                  A. Pursuant to a Stock Purchase Agreement (the "Stock Purchase
Agreement") dated September 28, 1999, between Advanced Lighting Technologies,
Inc., an Ohio corporation ("ALT"), and GE, GE has agreed to purchase seven
hundred sixty-one thousand two hundred fifty (761,250) shares of Series A
Convertible Preferred Stock, par value $.001 (the "Series A Shares"), of ALT.

                  B. It is a condition to the obligations of GE under the Stock
Purchase Agreement that the parties hereto execute this Agreement.

                  NOW, THEREFORE, in consideration of the foregoing and the
covenants contained herein, the parties agree as follows:

                  1. Definitions.

                  "Family Group" shall mean an individual's parents, children or
siblings and trusts for the benefit of such individual or such individual's
parents, children or siblings.

                  "Offer Notice" shall have the meaning provided in Section 2.

                  "Sale Notice" shall have the meaning provided in Section 3.

                  "Series A Shares" shall have the meaning ascribed thereto in
Recital A of this Agreement.

                  "Shares" shall mean any and all Common Shares, Preferred
Shares, other equity securities of the Company and rights, options or warrants
exercisable, exchangeable or convertible into equity securities of the Company
owned, of record or beneficially, by a Stockholder.

                  "Stockholder" shall mean any of Hellman, Hellman Ltd. or Ruud
and "Stockholders" shall mean Hellman, Hellman Ltd. and Ruud.

                  Transfer" shall mean a pledge, mortgage or other encumberance
on any Shares or any sale, transfer assignment or other disposition of any
interest in any Shares.

                  "Transferring Stockholder" shall mean any Stockholder that
determines to sell, transfer, assign or otherwise dispose of any interest,
whether owned beneficially or of record, in any Shares.

                  2. Right of First Refusal--Proposed Transfer by Stockholders.
With respect to any proposed Transfer of more than 1,000 Shares (whether in one
transaction or in a series of related transactions) by any single Stockholder,
the Transferring Stockholder shall first provide GE a right to purchase such
Shares by written notice (an "Offer Notice") to GE. The Offer Notice shall
disclose in reasonable detail the identity of the prospective transferee(s) or
that it is to be an open market sale, the proposed number of Shares to be
transferred and the proposed terms and conditions of the Transfer. GE may elect
to purchase all or any portion of the Shares specified in the Offer Notice at

<PAGE>

CUSIP NO. 00753C 10 2                 13D

the price and on the terms specified therein or at the market price, for any
open market sale, by delivering written notice of such election to the
Transferring Stockholder within (i) 48 hours after delivery of the Offer Notice
in the case of any open market sale and (ii) 20 days after delivery of the Offer
Notice in the case of any sale that is not an open market sale. If GE elects to
exercise its right to purchase all or a portion of the Shares, the closing of
the sale of the Shares shall be consummated within 30 days after GE delivers
written notice of such election to the Transferring Stockholder, subject to any
extension necessary to comply with any applicable regulatory requirements. To
the extent that GE has not elected to purchase all of the Transferring
Stockholder's Shares being offered, the Transferring Stockholder may, within (i)
10 days after the delivery of the Offer Notice in the case of any open market
sale and (ii) 120 days after the delivery of the Offer Notice in the case of any
sale that is not an open market sale, transfer any remaining offered Shares to
the transferee(s) identified in the Offer Notice at a price not less than the
price per share specified in the Offer Notice or at the market price, for any
open market sale, and on other terms no more favorable to such transferee(s)
than offered to GE in the Offer Notice. For the purposes of this Section 2,
Hellman and Hellman Ltd. shall be treated as a single Stockholder.

                  3. Right of Co-Sale. If any single Stockholder determines to
Transfer a total of more than 1,000 Shares other than in an open market sale
(whether in one transaction or in a series of related transactions) with respect
to any Shares not transferred to GE pursuant to Section 2 (the "Remaining
Shares"), such Transferring Stockholder shall offer to GE the option to
participate in the contemplated Transfer by written notice (a "Sale Notice") to
GE, specifying in reasonable detail the identity of the prospective
transferee(s), the number of Remaining Shares, and the terms and conditions of
the contemplated Transfer. GE may elect to participate in the contemplated
Transfer by delivering written notice to the Transferring Stockholder within 30
days after delivery of the Sale Notice. The Transferring Stockholder shall use
best efforts to obtain the agreement of the prospective transferee(s) to the
participation of GE in any contemplated Transfer and to the inclusion of a
transfer of Series A Shares in the contemplated Transfer, and the Transferring
Stockholder shall not transfer any of its Shares to the prospective
transferee(s) if the prospective transferee(s) declines to allow the
participation of GE or the inclusion of the Shares held by GE. For the purposes
of this Section 3, Hellman and Hellman Ltd. shall be treated as a single
Stockholder.


                  4. Transfers Not Subject to Agreement. The restrictions
contained in Section 2 and in Section 3 shall not apply with respect to any
Transfer in the case of either Stockholder to or among another Stockholder or to
or among such Stockholder's Family Group; provided that the restrictions
contained in Section 2 and in Section 3 shall continue to be applicable to the
Shares after any such Transfer; and further provided that the transferees of
such Shares shall have agreed in writing to be bound by the provisions of this
Agreement affecting the Shares so transferred.

                  5. Miscellaneous.

                  (a) Amendment and Waiver. Except as otherwise provided in this
Agreement, no modification, amendment or waiver of any provision of this
Agreement will be effective unless such modification, amendment or waiver is
approved in writing by GE. The failure of GE to enforce any of the provisions of
this Agreement will in no way be construed as a waiver of such provisions and
will not affect the right of GE thereafter to enforce each and every provision
of this Agreement in accordance with its terms.

                  (b) Severability. Whenever possible, each provision of this
Agreement will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or any other jurisdiction, but this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

                  (c) Entire Agreement. Except as otherwise expressly set forth
in this Agreement, this Agreement embodies the complete agreement and
understanding among the parties hereto with respect to the subject matter hereof
and supersedes and preempts any prior understandings, agreements or
representations by or among the parties, written or oral, which may have related
to the subject matter hereof in any way.

                  (d) Successors and Assigns. Except as otherwise provided in
this Agreement, this Agreement will bind and inure to the benefit of and be
enforceable by GE and its successors and assigns, and the Stockholders and their
respective representatives, successors and assigns.

                  (e) Counterparts. This Agreement may be executed in separate
counterparts, each of which, when executed, will be an original and all of which
taken together will constitute one and the same agreement.

                  (f) Remedies. Each Stockholder acknowledges and agrees that,
in the event such Stockholder should fail to perform the Stockholder's
obligations under this Agreement, the remedy at law available to any party
hereto aggrieved by such failure would be inadequate and that, in addition to
any other rights or remedies such aggrieved party may have at law or in equity,
the aggrieved party shall be entitled to specific performance of the provisions
of this Agreement or an injunction against any breach thereof, without the
necessity of proof of actual damage. Accordingly, with respect to any action or
proceeding brought by such aggrieved party to enforce the provisions hereof
against such Stockholder, each such Stockholder hereby waives the claim or
defense that such aggrieved party now has or hereafter shall have an adequate
remedy at law and such Stockholder hereby agrees not to assert such claim or
defense in any such action or proceeding. This provision shall not be construed
as precluding such aggrieved party from exercising any other rights, privileges
or remedies to which such party may be entitled, all of which rights, remedies
and privileges shall be deemed cumulative and none of which shall be deemed
exclusive. Except as otherwise expressly provided in this Agreement or otherwise
agreed to in writing executed by such aggrieved party, no course of dealing on
the part of, nor any omission or delay by, such aggrieved party shall operate as
a waiver of any such right, remedy or privilege, nor shall any single or partial
exercise or waiver of any such right, privilege or remedy preclude any other or
further exercise thereof or of any other right, privilege or remedy available to
such aggrieved party.

                  (g) Indemnification. Each Stockholder, and such Stockholder's
representatives, successors and assigns, shall defend, indemnify and hold
harmless GE, its representatives, successors and assigns (the "Indemnified
Parties") from and against any and all liabilities, obligations, claims, costs,
damages and expenses, including without limitation reasonable attorneys' fees
and additional tax liabilities and interest and penalties, incurred by any of
the Indemnified Parties as a result of the failure of performance of, or the
breach by, such indemnifying Stockholder of any of such Stockholder's
obligations contained in this Agreement.

                  (h) Notices. Any notice provided for in this Agreement shall
be in writing and shall be either personally delivered or mailed first-class
mail (postage prepaid) or sent by reputable overnight courier service (charges
prepaid) to the recipient at the address indicated on the records of ALT and to
any subsequent holder of Shares subject to this Agreement at such address as
indicated by the Company's records, or at such address or to the attention of
such other person as the recipient party has specified by prior written notice
to the sending party. Notices will be deemed to have been given hereunder when
delivered personally, three days after deposit in the U.S. mail and one day
after deposit with a reputable overnight courier service.

construed in accordance with the laws of the State of New York, without regard
to principles of conflicts of law.
