         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,

                                       11
<PAGE>   12

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, there are no outstanding options, offers, warrants, conversion
rights, agreements, or other rights to subscribe for or to purchase from the

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

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

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

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

<PAGE>   33

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.

                  "Business Day" shall mean any day that is not a Saturday or
Sunday or a day on which banks are required to be closed in the State of New
York.

                  "Commission" shall mean the Securities and Exchange Commission
or any other federal agency then administering the Securities Act, the Exchange
Act and other federal securities laws.

                  "Common Share" shall mean (except where the context otherwise
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

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

                                      -5-
<PAGE>   37

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,
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

                                      -6-
<PAGE>   38

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 cancelled. 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.

                  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:

                                      -7-
<PAGE>   39

                  (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
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

                                      -8-
<PAGE>   40

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.

                  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

                                      -9-
<PAGE>   41

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

                                      -10-
<PAGE>   42

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 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

                                      -11-
<PAGE>   43

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
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 cancelled 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

                                      -12-
<PAGE>   44

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,
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.

                                      -13-

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

                  (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,

                                      -14-
<PAGE>   46

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
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

                                      -15-
<PAGE>   47

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
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

                                      -16-
<PAGE>   48

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

                                      -17-
<PAGE>   49

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.

                  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.

<PAGE>   50

                  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.

                  (b)      If to the Company at

                           Advanced Lighting Technologies, Inc.

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,

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

                                      -19-
<PAGE>   51

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.

                  IN WITNESS WHEREOF, the Company has caused this Warrant to be
duly executed and attested by its Secretary or an Assistant Secretary.

III.   LIQUIDATION, DISSOLUTION OR WINDING UP.

         (a) TREATMENT AT LIQUIDATION, DISSOLUTION OR WINDING UP. Upon any

receive, prior and in preference to any distribution

                                    Page 5
<PAGE>   59

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% compounded annually from the date of issuance of each
Series A Preferred Share 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

                                    Page 6
<PAGE>   60

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).

                                    Page 7
<PAGE>   61

        (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:

                                (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,

                            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

                                    Page 8
<PAGE>   62

                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 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

                                    Page 9
<PAGE>   63

              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
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

                                    Page 10
<PAGE>   64

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 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

                                    Page 11
<PAGE>   65

         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 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 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

                                    Page 13
<PAGE>   67

         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,
unless such action will not have a materially adverse effect upon the rights of
holders of Series A Preferred Shares, the number of Common

                                    Page 14
<PAGE>   68

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

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.

                                    Page 16
<PAGE>   70

                  (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
to be redeemed shall surrender the certificate or certificates representing such
shares to the Corporation, and thereupon the applicable Redemption Price for
such shares as set forth in this Section 6 shall be paid to the order of the
person whose name appears on such certificate or certificates and each
surrendered certificate shall be cancelled and retired and new certificates
representing any Series A Preferred Shares not redeemed shall be issued to the
holder at no additional cost.

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

                                    Page 17
<PAGE>   71

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.

         (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

                                    Page 18
<PAGE>   72

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

shall be authorized to issue. The President or any Vice President and the

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

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

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

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 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.

         B. The Company and Purchaser are parties to a Stock Purchase Agreement,
dated September 28, 1999, under which the Company has agreed, among other

         C. The Company, Purchaser, the Shareholders and certain trusts
controlled by the Shareholders are parties to a Contingent Warrant Agreement of
even date herewith (the "Contingent Warrant Agreement"), under which the Company
has agreed to issue to Purchaser warrants to purchase Common Shares of the
Company upon the happening of certain events and the Shareholders have agreed to

         D. It is a condition to Purchaser's consummating the transactions

                  NOW, THEREFORE, based upon the foregoing premises and for

directly or indirectly controlling, controlled by, or under direct or indirect

value of Company, as determined by an investment banking or valuation firm
selected in accordance with the following sentences, divided by the number of

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 Purchaser and acceptable to the Shareholders. If the investment banking or
valuation firm selected by Purchaser is not acceptable to the Shareholders and
the Purchaser and the Shareholders cannot agree on a mutually acceptable
investment banking or valuation firm, then Purchaser and the Shareholders,
collectively, shall each choose one such investment banking or valuation firm

Shares, the average of the daily market prices for twenty (20) consecutive
Business Days immediately preceding such date or, if there is no such public
market, the Appraised Value per Common Share. The daily market price for each
such Business Day shall be (i) the last sale price on such day on the principal
stock exchange or NASDAQ-NMS on which such Common Shares are then listed or

exchange or NASDAQ-NMS, the average of the last reported closing bid and asked
prices on such day as officially quoted on any such exchange or NASDAQ-NMS, or

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

until 5:00 P.M., New York time, on the Expiration Date (the "Exercise Period"),
Holder may exercise this Warrant, on any Business Day, for all or any part of
the Warrant 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,

                                      -5-
<PAGE>   107

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) 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.

                  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,
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, the Current Warrant Price
per 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

                                      -6-
<PAGE>   108

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 cancelled. 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.

                  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

                  The number of Common Shares for which this Warrant is
exercisable, and the price at which such shares may be purchased upon exercise
of this Warrant, 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,

                                      -7-
<PAGE>   109

then (i) 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, and (ii) the Current Warrant Price shall be adjusted to equal (A) the
Current Warrant Price multiplied by the number of Common Shares for which this
Warrant is exercisable immediately prior to the adjustment divided by (B) the
number of shares for which this Warrant is exercisable immediately after the
adjustment.

                  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
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.[INTENTIONALLY OMITTED]

                  4.4. 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 to the Current Warrant Price provided for in Section 4:

                  (a) 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.

                                      -8-
<PAGE>   110

                  (b) 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.

                  (c) 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 cancelled by the Company and
escrowed property returned to the Company.

                  4.5. 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,
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 4.5,
"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

                                      -9-
<PAGE>   111

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 4.5 shall similarly apply to successive
reorganizations, reclassifications, mergers, consolidations or disposition of
assets.

                  4.6. 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, specifying the number of
Common Shares for which this Warrant is exercisable and (if such adjustment was
made pursuant to Section 4.5 or 4.6) 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

                  (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,

                                      -10-
<PAGE>   112

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

                  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,

                                      -12-
<PAGE>   114

         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
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 dated September 30,
1999, 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

                                      -13-
<PAGE>   115

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.

                  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,

                  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.

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

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.

                          To Purchase Common Shares of

                      ADVANCED LIGHTING TECHNOLOGIES, INC.

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 __________________ Common Shares (as

whole or in part, including fractional parts, at the Current Warrant Price (as
defined herein) 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

until 5:00 P.M., New York time, on the Expiration Date (the "Exercise Period"),
Holder may exercise this Warrant, on any Business Day, for all or any part of
the Warrant 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,

                                      -5-
<PAGE>   129

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) 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.

                  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,
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, the Current Warrant Price
per 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

                                      -6-
<PAGE>   130

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 cancelled. 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.

                  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

                  The number of Common Shares for which this Warrant is
exercisable, and the price at which such shares may be purchased upon exercise
of this Warrant, 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,

                                      -7-
<PAGE>   131

then (i) 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, and (ii) the Current Warrant Price shall be adjusted to equal (A) the
Current Warrant Price multiplied by the number of Common Shares for which this
Warrant is exercisable immediately prior to the adjustment divided by (B) the
number of shares for which this Warrant is exercisable immediately after the
adjustment.

                  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
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.[INTENTIONALLY OMITTED]

                  4.4. 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 to the Current Warrant Price provided for in Section 4:

                  (a) 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.

                                      -8-
<PAGE>   132

                  (b) 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.

                  (c) 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 cancelled by the Company and
escrowed property returned to the Company.

                  4.5. 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,
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 4.5,
"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

                                      -9-
<PAGE>   133

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 4.5 shall similarly apply to successive
reorganizations, reclassifications, mergers, consolidations or disposition of
assets.

                  4.6. 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, specifying the number of
Common Shares for which this Warrant is exercisable and (if such adjustment was
made pursuant to Section 4.5 or 4.6) 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.

                  (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

                  (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

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

                                      -11-
<PAGE>   135

                  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,

                                      -12-
<PAGE>   136

         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
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 dated September 30,
1999, 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

                                      -13-
<PAGE>   137

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.

                  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

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,

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

defense in any action for specific performance that a remedy at law would be
adequate.

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

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.

    AGREED-UPON PROCEDURES RELATED TO FINANCIAL COVENANT IN GENERAL ELECTRIC
                          CONTINGENT WARRANT AGREEMENT

1.       We compared the consolidated net income (loss), depreciation,
         amortization, provision for income taxes, interest expense and
         extraordinary gains and losses in the EBITDA Coverage Ratio schedule
         with the corresponding dollar amount included in the Company's
         unaudited condensed consolidated financial statements included in the
         Company's Quarterly Report on Form 10-Q and found the amounts to be in
         agreement.

2.       We compared the dollar amounts in the EBITDA Coverage Ratio schedule
         not directly derived from the unaudited financial statements to the
         corresponding dollar amounts derived from the Company's accounting
         records and found them to be in agreement.

3.       We proved the arithmetical accuracy of EBITDA, as defined, and Interest
         Expense, as defined, and found the amounts to be in agreement with the
         amounts in the EBITDA Coverage Ratio schedule.

4.       We recalculated the EBITDA Coverage Ratio and Average EBITDA Coverage
         Ratio for the respective Determination Period and found the amounts
         calculated to be in agreement with the amounts in the EBITDA Coverage
         Ratio schedule.
