                          (Dollar amounts in thousands)



A. ORGANIZATION

Advanced Lighting Technologies, Inc. (the "Company" or "ADLT") is an
innovation-driven designer, manufacturer and marketer of metal halide lighting
products, including materials, system components, systems, and production
equipment.


B. BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions for Form 10-Q and Article 10 of
Regulation S-X. Accordingly, they do not include all the information and
disclosures required by generally accepted accounting principles for complete
financial statements. In the opinion of management, the financial statements
include all material adjustments necessary for a fair presentation, consisting
of normal recurring accruals. For further information, refer to the consolidated
financial statements and notes thereto included in the Company's annual report
on Form 10-K for the year ended June 30, 1999. Operating results for the three
months ended September 30, 1999 are not necessarily indicative of the results
that may be expected for the full-year ending June 30, 2000.

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect reported amounts and related disclosures. Actual results could differ
from those estimates.

Accounting Change - Cost of Start-Up Activities

During the fourth quarter of fiscal 1999, the Company adopted Statement of
Position ("SOP") 98-5, "Reporting on the Costs of Start-Up Activities,"
effective July 1, 1998. The first quarter of fiscal 1999 has been restated to
reflect the cumulative effect of the accounting change.

New Accounting Standards

The Company has not yet adopted Statement of Financial Accounting Standards
("FAS") No. 133, "Accounting for Derivative Instruments and Hedging Activities."
FAS No. 133 requires that all derivatives, such as interest rate exchange
agreements (swaps), be recognized on the balance sheet at fair value.
Derivatives which are not hedges must be adjusted to fair value through the
results of operations. Derivatives determined to be hedges will be adjusted to
fair value through either the results of operations or other comprehensive
income, depending on the nature of the hedge. The Company is required to adopt
FAS No. 133, as subsequently amended by FAS No. 137, on July 1, 2000. The
impact, if any, on net income, comprehensive income and financial position will
depend on the amount, timing and nature of any agreements entered into by the
Company.

Financial Statement Presentation Changes

Certain amounts for prior periods have been reclassified to conform to the
current period reporting presentation.


C. COMPREHENSIVE INCOME

Statement of Financial Accounting Standards (FAS) No. 130, "Reporting
Comprehensive Income," requires disclosure of comprehensive income and its
components. FAS No. 130 requires companies to report, in addition to net income,
other components of comprehensive income, which for the Company includes foreign
currency translation adjustments.

For the three months ended September 30, 1999 and 1998, the Company's
comprehensive loss was $(434) and $(1,995), respectively.


D. BANK CREDIT FACILITY

In May 1999, the Company replaced its existing Credit Facility with a $50,000
revolving credit loan and $25,000 term loan provided by several financial
institutions. Subsequent to June 30, 1999 the Company reduced its commitment to
a $60,000 facility. Proceeds from the facility were used to repay the Company's
existing credit facility and certain other long-term debt. The revolving credit
loan has a three-year term expiring in May 2002. Interest rates on revolving
credit loans outstanding are based, at the Company's option, on LIBOR plus 2.75%
or the agent bank's prime rate. Availability of borrowings is determined by the
Company's eligible accounts receivable and inventories. The term loan has a
five-year term expiring in May 2004. The Company pays monthly principal payments
that total $3,576 annually, with the unpaid balance due at maturity. Interest
rates on the term loan are based, at the Company's option, on LIBOR plus 3.25%
or the agent bank's prime rate.

The Bank Credit Facility contains certain affirmative and negative covenants
customary for this type of agreement, prohibits cash dividends, and includes
financial covenants with respect to the coverage of certain fixed charges. The
principal security for the revolving credit loan is substantially all of the
personal property of the Company and each of its North American and United
Kingdom subsidiaries. The term loan is secured by substantially all of the
Company's machinery and equipment and is cross-collateralized and secured with
the revolving credit loan.

E. SENIOR NOTES OFFERING

On March 13, 1998, the Company sold $100,000 of Senior Notes due March 15, 2008,
resulting in net proceeds of approximately $96,150. The Notes have an annual
coupon rate of 8% and are redeemable at the Company's option, in whole or in
part, on or after March 15, 2003 at certain preset redemption prices. In
addition, at any time prior to March 15, 2001, the Company may redeem up to 35%
of the aggregate principal amount of the Notes at 108% of par with the proceeds
of one or more public equity offerings. Interest on the Senior Notes is payable
semiannually on March 15 and September 15 of each year beginning on September
15, 1998. There are no sinking fund requirements.

From September 14, 1998, until the completion of a registered exchange offer to
existing noteholders, the Senior Notes bear interest at 8.5%. The offer is
expected to be completed within 45 days following the effectiveness of the
Company's related registration statement.

The Notes Indenture contains covenants that, among other things, limit the
ability of the Company and its Restricted Subsidiaries (as defined therein) to
incur indebtedness, pay dividends, prepay subordinated indebtedness, repurchase
capital stock, make investments, create liens, engage in transactions with
stockholders and affiliates, sell assets and, with respect to the Company,
engage in mergers and consolidations.


F. SPECIAL CHARGES

At September 30, 1999, the Company had an accrual principally related to the
execution of the Company's fiscal 1999 shift in strategic direction intended to
accelerate and intensify the Company's focus on its metal halide products. The
accrual relates to: limiting Pacific Rim expansion; changing global lamp
manufacturing strategy; restructuring marketing operations in North America and
Europe; accelerating an exit from noncore product lines; reducing excess
overhead including staffing reductions; consolidating an equipment manufacturing
operation into the Company's Solon, Ohio facility and significantly reducing the
size of the operation; and, reducing capital expenditures. All actions required
by the plans are expected to be completed by March 31, 2000. The amounts the
Company will ultimately incur may change as the Company's plans are executed and
actions are completed.

G.  DISCONTINUED OPERATIONS SUBSEQUENTLY RETAINED

Microsun Technologies, Inc. ("Microsun") was identified in March 1998 for
disposition through a plan to distribute to ADLT shareholders all of the
ownership of Microsun in a tax-free spin-off transaction estimated to be
completed by December 1998. Because of the deterioration of the capital markets
and the inability to raise capital necessary to spin-off the Microsun business,
the Company concluded that it would wind-down the operations, close the
manufacturing facilities and liquidate the assets of Microsun. At June 30, 1999,
the plan of wind-down had been accomplished, the manufacturing facilities closed
and substantially all assets had been disposed. Accordingly, there were no
remaining discontinued operations accrued losses associated with Microsun at
June 30, 1999.

In October 1999, management decided, with the approval of the Board of
Directors, to retain the Microsun business as part of the Company's continuing
operation. The decision to retain the business was based on management's belief
that, among other reasons, the market demand for Microsun products remains
substantial; the market potential will be expanded as the Microsun portable
lighting fixtures will be marketed and sold along with other existing lines of
products for residential use in an e-commerce format ("Microsun.com"); and the
Microsun business will use the fulfillment capabilities and infrastructure of
existing ADLT businesses.

In accordance with generally accepted accounting principles, the accompanying
financial statements have been reclassified to present Microsun within
continuing operations.

H. RELATED PARTY TRANSACTION

Pursuant to a loan agreement dated October 8, 1998, between the Company and its
Chairman and Chief Executive Officer (the "CEO"), the Company loaned $9,000 to
its CEO for a one-year term at an interest rate of 8%. The loan was made
following approval by the Company's Board of Directors. The proceeds of the loan
were used by the Company's CEO to reduce the outstanding principal balance of a
margin account loan, which is secured by 2,053,070 shares of the Company's
Common Stock owned by the CEO and a related entity. In connection with the loan,
the Company's Board of Directors asked for and received the CEO's agreement to
extend the term of his employment agreement to December 31, 2003. The loan
agreement prohibits the CEO from encumbering his shares of the Company's Common
Stock in any manner except pursuant to the existing agreements governing the
CEO's margin account, without the consent of the Company's Board of Directors.

The CEO has paid accrued interest of $720 on the loan through October 6, 1999.
The principal on the loan was due on October 6, 1999. Members of the Board of
Directors and the CEO are discussing alternative payment terms which will
achieve the Board's original business objectives in making the loan and meet the
Company's current business needs. The Directors and the CEO believe that these
discussions will be completed by January 2000. The Board has informed the CEO
that the Company may require immediate payment during these discussions if the
Company requires the payment to prevent an unacceptable strain on cash
resources.


I. CONTINGENCY

In April and May 1999, three class action suits were filed in the United States
District Court, Northern District of Ohio, by certain alleged shareholders of
the Company on behalf of themselves and purported classes consisting of Company
shareholders, other than the defendants and their affiliates, who purchased
stock during the period from December 30, 1997 through September 30, 1998 or
various portions thereof. A First Amended Class Action Complaint, consolidating
the three lawsuits, was filed on September 30, 1999, and the action is now
pending before a single judge. The named defendants in the case - styled In re
Advanced Lighting Technologies, Inc. Securities Litigation, Master File No.
1:99CV836, pending before the United States District Court, Northern District of
Ohio - are the Company and its Chairman and Chief Executive Officer.

The First Amended Class Action Complaint alleges generally that certain
disclosures attributed to the Company contained misstatements and omissions
alleged to be violations of Section 10(b) of the Securities Exchange Act of 1934
and Rule 10b-5, including claims for "fraud on the market" arising from alleged
misrepresentations and omissions with respect to the Company's

financial performance and prospects and alleged violations of generally accepted
accounting principles by, among other things, improperly recognizing revenue and
improper inventory accounting. The Complaint seeks certification of the
purported class, unspecified compensatory and punitive damages, pre- and
post-judgment interest and attorneys' fees and costs.

The Company and the CEO believe that these claims lack merit and they intend to
vigorously defend against these actions.


J. SUBSEQUENT EVENT -- GENERAL ELECTRIC COMPANY INVESTMENT

During September 1999, General Electric Company ("GE") executed a definitive
agreement to make an investment in the Company of $20,554. During October 1999,
GE completed the investment in the Company. In exchange for the investment, GE
received 761,250 shares of the Company's newly-created Series A Stock
convertible at any time into 3,045,000 shares of Company Common Stock (subject
to adjustment). GE also received a Warrant (the "Initial Warrant") to purchase
an additional 1,000,000 shares of Company Common Stock (subject to adjustment),
which is immediately exercisable at $.01 per share. GE has been a holder of
535,887 shares of Company Common Stock since the Company's initial public
offering in 1995. The Series A Stock, Common Stock issuable on exercise of the
Initial Warrant, and the Common Stock held by GE represent (after giving effect
to the shares issued on exercise of the Initial Warrant) approximately 18.8% of
the voting power and equity ownership of the Company after the GE investment.
The proceeds of the transaction were applied principally to the reduction of
short-term liabilities and outstanding amounts under the Company's Bank Credit
Facility.

The Series A Stock has a liquidation preference of $27 per share, plus an amount
equal to 8% per annum from the date of issuance to the date of payment
("Liquidation Preference Amount"). The Company is required to redeem any shares
of Series A Stock which have not been converted or retired on September 30,
2010. In addition, GE may, by notice, require the Company to redeem the
outstanding Series A Stock, within one year following either September 30, 2004,
or the occurrence of certain corporate events. If the Company fails to maintain
certain financial ratios, GE will have the right to acquire a combination of
subscription rights to additional shares and proxies with respect to shares
voted by certain officers of the Company, giving GE the ability to obtain the
majority of the voting power of the Company.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.
(Dollar amounts in thousands)

This report on Form 10-Q may contain forward-looking statements. For this
purpose, any statement contained herein that is not a statement of historical
fact may be deemed to be a forward-looking statement. Without limiting the
foregoing, the words "believes," "anticipates," "plans," "expects," and similar
expressions are intended to identify forward-looking statements. There are a
number of factors that could cause the Company's actual results to differ
materially from those indicated by such forward-looking statements. Such factors
are detailed in the Company's Annual Report on Form 10-K for the fiscal year
ended June 30, 1999 filed with the Securities and Exchange Commission.

The following is management's discussion and analysis of certain significant
factors which have affected the results of operations and should be read in
conjunction with the accompanying unaudited Condensed Consolidated Financial
Statements and notes thereto.

GENERAL

The Company designs, manufactures and markets metal halide lighting products,
including materials, systems and components. Metal halide lighting is currently
used primarily in commercial and industrial applications such as factories and
warehouses, outdoor site and landscape lighting, sports facilities and large
retail spaces such as superstores. With the January 1998 acquisition of
Deposition Sciences, Inc.("DSI"), the Company also manufactures and markets
turnkey deposition equipment to produce thin film coatings for a variety of
applications. Systems, components and materials revenue is recognized when
products are shipped, and deposition equipment revenue is recognized under the
percentage of completion method.

Consistent with the Company's strategy for new product introductions, the
Company invests substantial resources in research and development to engineer
materials and system components to be included in customers' specialized
lighting systems. Over the last three fiscal years, the Company has spent an
aggregate of $31,539 on research and development, representing 7.2% of aggregate
net sales from continuing operations over that period. Such expenditures have
enabled the Company to develop new applications for metal halide lighting,
improve the quality of its materials, and introduce new specialized products,
such as the Uni-Form(R) pulse start products. Uni-Form(R) pulse start products
are a new generation of metal halide components and systems which permit (a)
increased light output with lower power utilization, (b) faster starting, (c) a
quicker restart of lamps which have been recently turned off, and (d) better
color uniformity. The Company has spent additional amounts for manufacturing
process and efficiency enhancements, which were charged to cost of goods sold
when incurred. The Company expects to continue to make substantial expenditures
on research and development to enhance its position as the leading innovator in
the metal halide lighting industry.

The Company also has invested substantial resources in acquisitions and
strategic investments. In January 1998, the Company acquired Ruud Lighting, Inc.
and DSI. These acquisitions enabled the Company to complete the assembly of the
necessary operations to take a leadership role in the development, manufacturing
and marketing of new and better systems in the growing metal halide lighting
industry.

RECENT DEVELOPMENTS

GENERAL ELECTRIC COMPANY INVESTMENT

On September 28, 1999, General Electric Company ("GE") entered into a definitive
agreement to make an investment in the Company of $20,554. On October 6, 1999,
GE completed the investment in the Company.

The additional capital resources provided by the GE investment are expected to
provide additional flexibility to pursue opportunities in the metal halide
business. In addition, GE and the Company have entered into a five year,
renewable agreement for the supply of metal halide salts to GE. The Company and
GE are in discussions with respect to other supply arrangements. The Company
anticipates that the GE investment and the expansion which it will permit will
result in an expanded supplier-customer relationship with GE, enhancing the
Company's earnings and competitive position in the metal halide marketplace.

The GE investment includes 761,250 shares of the Company's newly-created Series
A Stock convertible at any time into 3,045,000 shares of Company Common Stock
(subject to adjustment). GE also received a Warrant (the "Initial Warrant") to
purchase an additional 1,000,000 shares of Common Stock of the Company (subject
to adjustment), which is immediately exercisable. GE has been a holder of
535,887 shares of Company Common Stock since the Company's initial public
offering in 1995. The Series A Stock, Common Stock issuable on exercise of the
Initial Warrant and the Common Stock held by GE represent (after giving effect
to the shares issued on exercise of the Initial Warrant) approximately 18.8% of
the voting power and equity ownership of the Company. See "Terms of the Series A
Stock" and "Terms of the Initial Warrant." Pursuant to the terms of the Stock
Purchase Agreement, GE is to provide the Company with five nominees as potential
Company's Board of Directors who are not directors, officers, employees or 10%
shareholders of GE. The Company is required to cause the number of such nominees
serving on the Board to be equal to the greater of 20% of the number of members
of the Board or the number of members which most nearly corresponds to GE's
percentage ownership interest in the Company.

The proceeds of the GE transaction have been applied principally to the
reduction of short-term liabilities and outstanding amounts under the Company's
Credit Facility, and have the effect of increasing available borrowings under
the Company's Credit Facility.

The following summaries of the terms of the Series A Stock, the Terms of the
Initial Warrant and Additional Terms of the GE Transaction are summaries of the
definitive documents in connection with the GE investment.

Terms of the Series A Stock

The Series A Stock is a newly authorized series of preferred stock of the
Company created for issuance in the GE transaction. 761,250 shares of Series A
Stock have been authorized and issued to GE. The Series A Stock has a
liquidation preference of $27 per share, plus an amount equal to 8% per annum
from the date of issuance to the date of payment ("Liquidation Preference
Amount").



                                       13
<PAGE>   15

Each outstanding share of Series A Stock is convertible at any time into four
shares (subject to adjustment as described below) of Common Stock of the
Company. Prior to conversion, holders of Series A Stock are entitled to vote in
all shareholder matters together with the holders of Company Common Stock as a
single class. In any such vote, the holders of Series A Stock are entitled to
four votes (equal to the number of shares of Common Stock into which the Series
A Stock held may initially be converted).

The Company is required to redeem any shares of Series A Stock which have not
been converted or retired on September 30, 2010. Any such redemption would be
made at the Liquidation Preference Amount. In addition, holders of the Series A
Stock may require the Company to redeem their shares of Series A Stock by giving
notice to the Company on or before September 30, 2004. If such notice is given,
the Company will be required to make such redemption on or prior to September
30, 2005. In addition, holders of Series A Stock will be entitled to require the
Company to redeem the Series A Stock following the occurrence of any of the
following events (each a "Triggering Event"): (1) failure of the shareholders of
the Company to approve, at the 1999 annual meeting, proposals necessary for
exercise of any rights to acquire beneficial ownership of additional shares of
Common Stock as described in "Additional Terms of the GE Transaction"; or (2)
any action by the Company to give effect to certain major corporate actions,
including actions to merge, sell all or a substantial portion of its assets
(other than in the ordinary course of business), issue capital stock, incur or
have outstanding indebtedness for borrowed money in excess of $210,000. Upon the
occurrence of a Triggering Event, the holders of the Series A Stock may require
the Company to redeem their shares of Series A Stock by giving notice to the
Company within 90 days following the Triggering Event. If such notice is given,
the Company will be required to make such redemption within one year following
such notice. Any such redemption would be made at the Liquidation Preference
Amount. Under the terms of the bank's revolving credit facility and the
indenture (the "Indenture") relating to the Company's Senior Notes due 2008, the
redemption of the Series A Stock would currently constitute an event of default,
permitting acceleration of the related indebtedness. If prior consent of the
banks is obtained, the redemption is permitted under the credit facility.
Payments for the redemption of equity securities are "Restricted Payments" under
the Indenture. The total of all "Restricted Payments" under the Indenture (with
exceptions not applicable to stock redemption) cannot exceed one-half of the
total of consolidated net earnings of the Company (excluding consideration of
certain unusual items) from April 1, 1998 (taken as a single period) plus the
amount of proceeds received from sales of non-redeemable stock. As of September
30, 1999, the Company had a net loss, excluding extraordinary items, of $79,442
for the period. Until this deficit has been cured, the Company cannot redeem the
Series A Stock without causing an event of default with respect to the Senior
Notes. In addition, the Indenture prohibits Restricted Payments (with exceptions
not applicable to stock redemptions) at any time where the ratio of EBITDA to
Interest Expense for the preceding four fiscal quarters does not exceed 2.5
to 1.

Subject to approval by Company shareholders, if the Company fails to make any
redemption as required (subject to permitted deferrals in the event that such
redemption would cause an event of default with respect to certain indebtedness
of the Company), the conversion ratio of the Series A Stock would be increased
from four shares of Common Stock to eight shares of Common Stock per share of
Series A Stock. In addition, also subject to the approval of Company
shareholders, the conversion ratio will be subject to adjustment to prevent
dilution of the interest of GE by the issuance of Common Stock after October 6,
1999. Except for issuance

                                       14
<PAGE>   16


of shares under existing employee benefit plans, and certain other enumerated
exceptions, any shares of Common Stock issued at a price below $6.75 per share,
or, if higher, below the then current market price, would result in adjustment
of the conversion ratio. Any adjustment in the conversion ratio would not affect
the voting power represented by shares of Series A Stock prior to conversion.

Upon liquidation, each share of Series A Stock will be entitled to be paid the
Liquidation Preference Amount prior to any payment or distribution to the
holders of Company Common Stock. Following such payment, holders of Series A
Stock will be entitled to a proportional share of any distribution to holders of
Company Common Stock based on the number of shares of Common Stock into which
the Series A Stock could have been converted at the time of the liquidation.

Terms of the Initial Warrant

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

Additional Terms of the GE Transaction

In addition to GE's initial investment, under certain circumstances, GE will be
entitled to make additional investments in the Company and receive the right to
vote additional shares of Company Common Stock. The exercise of certain of these
rights is subject to applicable law, including the Ohio Control Share
Acquisition Act and the Hart-Scott-Rodino Antitrust Improvements Act of 1976
("HSR Approval"). GE and the Company entered into a Contingent Warrant Agreement
("Contingent Warrant Agreement"). The Contingent Warrant Agreement identifies
certain occurrences which will entitle GE to exercise these rights.

Upon the Second Occurrence (defined below), if it occurs, GE would be required
to exercise in full the Initial Warrant. In addition, GE would receive the right
to vote the number of shares then owned by Wayne R. Hellman and Hellman, LTD.
pursuant to proxies granted by Messrs. Hellman and Ruud. GE would receive the
right to vote the number of shares as to which Mr. Hellman then has voting power
pursuant to the Hellman Voting Trust or Irrevocable Proxies granted with respect
to shares removed from the Hellman Voting Trust (all shares voted by Mr.
Hellman, currently approximately 3.9 million shares, are referred to
collectively as the "Hellman Shares"). GE would also have an option, at the then
current market price, to purchase from Messrs. Hellman and Ruud, the number of
shares of Common Stock which, together with the shares owned by GE, would
represent 25% of the voting power of the Company. The Company would also be
required to grant to GE an additional warrant (the "First Contingent Warrant")
to purchase shares of Company Common Stock at the then current market price. The
number of shares subject to the First Contingent Warrant would be equal to the
number of shares required to allow GE to have a majority of the voting power of
the Company, assuming GE had effective proxies with respect to all shares as to
which Messrs. Hellman and Ruud then have voting power.


                                       15
<PAGE>   17


The exercise of the First Contingent Warrant, the options on shares held by
Messrs. Hellman and Ruud, and effectiveness of GE's proxy with respect to any
such shares, is subject to prior compliance with the Ohio Control Share
Acquisition Act (which condition would be fulfilled by shareholder approval to
be sought at the Company's annual meeting) and HSR Approval (which requires the
Company and GE to provide information to the federal government to allow it to
determine whether to contest an increase by GE to an interest in the Company in
excess of 25% pursuant to antitrust law). If the proxies become effective after
the Second Occurrence, GE will have the proxies to vote the number of Hellman
Shares and will be entitled to exercise approximately 35% of the then
outstanding voting power of the Company (assuming that none of the Hellman
Shares have been transferred by the beneficial owners and no issuance of
additional shares by the Company other than pursuant to the GE transaction) or
approximately 34% of the voting power of the Company on a fully diluted basis.
GE has not indicated that it will acquire additional shares of Company Common
Stock. However, if GE were to acquire additional shares of Common Stock (other
than shares subject to effective proxies as described above or shares obtained
on the exercise of the First Contingent Warrant), or if the number of
outstanding shares on a fully diluted basis were reduced, GE could obtain in
excess of 35% of the voting power of the Company on a fully diluted basis. In
addition, if a substantial number (currently approximately 300,000 shares) of
Hellman Shares were transferred (other than to GE) prior to the Second
Occurrence, and if GE exercised the First Contingent Warrant, GE would acquire
in excess of 35% of the voting power of the Company on a fully diluted basis. If
GE were to acquire in excess of 35% of the voting power of the Company on a
fully diluted basis, the terms of the Indenture relating to the Senior Notes
would require that the Company offer to repurchase the $100,000 principal amount
of outstanding Senior Notes due 2008 at a price of 101% of the principal amount
thereof, plus accrued interest ("Offer to Repurchase Notes").

Upon the Third Occurrence (defined below), GE would receive the right to vote
the number of shares then owned by Mr. Ruud, and the right to vote the number of
shares as to which Mr. Ruud then has voting power pursuant to the Ruud Voting
Trust or Irrevocable Proxies granted with respect to shares removed from the
Ruud Voting Trust, currently approximately 3.6 million shares (the "Ruud
Shares"). The effectiveness of this right requires that the conditions for the
effectiveness of the proxies following the Second Occurrence have been
satisfied, and that any additional provisions of the Ohio Control Share
Acquisition Act required with respect to proxies or the Ruud Shares be
satisfied. If the proxies on the Ruud Shares become effective after the Third
Occurrence, GE will have the right to vote the Ruud Shares and will be entitled
to exercise approximately 48.4% of the then outstanding voting power of the
Company (assuming that none of the Hellman Shares or the Ruud Shares have been
sold by the beneficial owners, no exercise by GE of the Contingent Warrants and
no issuance of additional shares by the Company other than pursuant to the GE
transaction). If the Company has not already made an Offer to Repurchase Notes,
it will be required to make the offer upon effectiveness of the proxy on the
Ruud Shares. In addition, GE will receive an additional warrant (the "Second
Contingent Warrant") which will entitle GE to purchase additional shares of
Common Stock at the then current market price. The number of shares subject to
the Second Contingent Warrant will be the number of shares necessary to give GE
50% plus one vote of the voting power of the Company (including the exercise of
all outstanding Warrants, shares subject to irrevocable proxies, the shares
subject to the Second Contingent Warrant and all proxies held with respect to
Hellman Shares and Ruud Shares). Subject to shareholder approval, after the
Third Occurrence,


                                       16
<PAGE>   18


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

The basis for GE's additional rights will be the failure of the Company to
maintain a 2.0 to 1.0 ratio of EBITDA (as defined) to Interest Expense (as
defined) over the applicable measurement periods. The first measurement period
is the six months ended December 31, 1999. Thereafter, the measurement periods
are the six months ending on the last day of each successive fiscal quarter
until September 30, 2010. The first failure to maintain the required ratio would
be the "First Occurrence," the second such failure would be the "Second
Occurrence" and the third such failure would be the "Third Occurrence." However,
after the First Occurrence, if the Company maintains the required ratio in the
three fiscal quarters immediately prior to the measurement period in which a
failure occurs, a Second Occurrence or Third Occurrence, as the case may be,
would not be effective, if the Company maintained the required ratio for the
measurement period immediately following the measurement period in which such
occurrence would otherwise have been effective. Under the terms of the
transaction, EBITDA consists of net earnings, plus interest expense, plus
depreciation and amortization, plus income taxes, less extraordinary gains and
gains from asset sales plus extraordinary losses and losses from asset sales.
Interest Expense consists of interest expense (net of interest income)
calculated in accordance with generally accepted accounting principles, but
excludes amortization of deferred financing costs not exceeding $125 in any
fiscal quarter.

DISCONTINUED OPERATIONS SUBSEQUENTLY RETAINED

Microsun Technologies, Inc. ("Microsun") was identified in March 1998 for
disposition through a plan to distribute to ADLT shareholders all of the
ownership of Microsun in a tax-free spin-off transaction estimated to be
completed by December 1998. Because of the deterioration of the capital markets
and the inability to raise capital necessary to spin-off the Microsun business,
the Company concluded that it would wind-down the operations, close the
manufacturing facilities and liquidate the assets of Microsun. At June 30, 1999,
the plan of wind-down had been accomplished, the manufacturing facilities closed
and substantially all assets had been disposed. Accordingly, there were no
remaining discontinued operations accrued losses associated with Microsun at
June 30, 1999.

In October 1999, management decided, with the approval of the Board of
Directors, to retain the Microsun business as part of the Company's continuing
operation. The decision to retain the business was based on management's belief
that, among other reasons, the market demand for Microsun products remains
substantial, the market potential will be expanded as the Microsun portable
lighting fixtures will be marketed and sold along with other existing lines of
products for residential use in an e-commerce format ("Microsun.com"), and the
Microsun business will use the fulfillment capabilities and infrastructure of
existing ADLT businesses.

In accordance with generally accepted accounting principles, the accompanying
financial statements have been reclassified to present Microsun within
continuing operations.

BANK CREDIT FACILITY

In May 1999, the Company replaced its existing Credit Facility with a $50,000
revolving credit loan and $25,000 term loan provided by several financial
institutions. Subsequent to June 30, 1999 the Company reduced its commitment to
a $60,000 facility. Proceeds from the facility were used to repay the Company's
existing credit facility and certain other long-term debt. The revolving credit
loan has a three-year term expiring in May 2002. Interest rates on revolving
credit loans outstanding are based, at the Company's option, on LIBOR plus 2.75%
or the agent bank's prime rate. Availability of borrowings is determined by the
Company's eligible accounts receivable and inventories. The term loan has a
five-year term expiring in May 2004. The Company pays monthly principal payments
that total $3,576 annually, with the unpaid balance due at maturity. Interest
rates on the term loan are based, at the Company's option, on LIBOR plus 3.25%
or the agent bank's prime rate.

The Bank Credit Facility contains certain affirmative and negative covenants
customary for this type of agreement, prohibits cash dividends, and includes
financial covenants with respect to the coverage of certain fixed charges. The
principal security for the revolving credit loan is substantially all of the
personal property of the Company and each of its North American and United
Kingdom subsidiaries. The term loan is secured by substantially all of the
Company's machinery and equipment and is cross-collateralized and secured with
the revolving credit loan.

UPDATE ON IN-PROCESS RESEARCH AND DEVELOPMENT

The Company's research and development projects acquired in connection with the
January 1998 acquisition of Deposition Sciences, Inc. are generally progressing
in line with the estimates set forth in the Company's 1999 Annual Report on Form
10-K.

Factors which have affected the results of operations for the first quarter of
fiscal 2000 as compared to the first quarter of fiscal 1999 are discussed below.

QUARTER ENDED SEPTEMBER 30, 1999 COMPARED WITH QUARTER ENDED SEPTEMBER 30, 1998

Net sales. Net sales increased 9.5% to $56,180 in the first quarter of fiscal
2000 from $51,287 in the first quarter of fiscal 1999. Sales in the first
quarter of fiscal 1999 included lamp equipment sales of $2,554. The first
quarter of fiscal 1999 is the last quarter in which the Company recorded lamp
equipment sales. Excluding these sales, net sales increased 15.3% from $48,733
in the first quarter of fiscal 1999.

Fiscal 2000 first quarter sales reflect continued growth in the sales of the
Company's core U.S. metal halide operations, in non-metal halide products, and
in overseas sales. The Company's metal halide sales increased 9% (10% increase
in the United States) from the year ago period, excluding lamp equipment sales
in the first quarter of fiscal 1999. The Company's core metal


                                       19
<PAGE>   21


halide materials business, a key indicator of industry trends, was up 28% from
fiscal 1999. Geographically, these sales of materials were up 16% in the U.S.
and grew 47% outside the U.S. Sales of Uni-Form(R) pulse start products continue
to accelerate to an estimated 6% share of new metal halide installations.

Sales outside the U.S. increased 14%, excluding the lamp equipment sales in the
first quarter of fiscal 1999. The Company attributes the increase in these sales
to the resurgence and recovery of foreign economies, especially in the Pacific
Rim. Sales of non-metal halide products grew 36%, representing strong sales of
the Company's materials, particularly thin-film optical coating materials.

Sales increases were driven by increased volume in the Company's materials,
components and systems. Pricing in the metal halide lighting business is
competitive, and prices for the Company's products have remained flat or
declined slightly. The introduction of new products has helped to stabilize the
Company's product pricing.

Cost of Sales. Cost of sales increased 12.7% to $34,844 in the first quarter of
fiscal 2000 from $30,904 in the first quarter of fiscal 1999. The increase was
primarily attributable to increased unit volume. As a percentage of net sales,
cost of sales increased to 62.0% in the first quarter of fiscal 2000 from 60.3%
in the first quarter of fiscal 1999.

Marketing and Selling Expenses. Marketing and selling expenses increased 8.2% to
$10,175 in the first quarter of fiscal 2000 from $9,401 in the first quarter of
fiscal 1999. Marketing and selling expenses, as a percentage of net sales,
remained relatively comparable at 18.1% in the first quarter of fiscal 2000 as
compared to 18.3% in the first quarter of fiscal 1999.

Research and Development Expenses. Research and development expenses decreased
11.9% to $3,495 in the first quarter of fiscal 2000 from $3,965 in the first
quarter of fiscal 1999. Research and development expenses are incurred related
to: (i) expansion of the new line of Uni-Form (R) pulse start lamps (with
improved energy efficiency, quicker starting and restarting and a more compact
arc source, which improves the light and reduces material costs) intended to
replace many first generation metal halide lamps in industrial and commercial
applications; (ii) development and testing of electronic power supply systems;
(iii) development of new materials for the world's major lighting manufacturers;
and, (iv) research and development efforts aimed at improving the coating
process of optical thin-films to broaden the applications, developing new
thin-film materials, and using coatings to develop improvements to lighting and
telecommunications technologies. The decrease in research and development was
primarily a result of a reduction in spending related to the development of
pulse start lamps. As a percentage of net sales, research and development
expenses decreased to 6.2% in the first quarter of fiscal 2000 from 7.7% in the
first quarter of fiscal 1999.

General and Administrative Expenses. General and administrative expenses
decreased 10.4% to $4,035 in the first quarter of fiscal 2000 from $4,505 in the
first quarter of fiscal 1999. As a percentage of net sales, general and
administrative expenses decreased to 7.2% in the first quarter of fiscal 2000
from 8.8% in the first quarter of fiscal 1999. The decrease as a percentage of
net sales primarily reflects a spending growth rate which is lower than sales
increases through the leveraging of fixed costs as sales levels increase and
also reflects the Company's efforts to control general and administrative costs.



                                       20
<PAGE>   22

Amortization of Intangible Assets. Amortization expense increased slightly to
$675 in the first quarter of fiscal 2000 from $665 in the first quarter of
fiscal 1999. Amortization expense relates primarily to the amortization of
goodwill and other intangible assets related to the January 1998 acquisitions of
Ruud Lighting, Inc. and Deposition Sciences, Inc.

Income from Operations. As a result of the items noted above, income from
operations in the first quarter of fiscal 2000 increased to $2,956 from $1,847
in the first quarter of fiscal 1999. As a percentage of net sales, income from
operations increased to 5.3% in the first quarter of fiscal 2000 from 3.6% in
the first quarter of fiscal 1999.

Interest Expense. Interest expense increased to $3,790 in the first quarter of
fiscal 2000 from $2,741 in the first quarter of fiscal 1999. This increase
resulted primarily from the higher average debt outstanding during the first
quarter of fiscal 2000 as compared to the first quarter of fiscal 1999, and to a
lesser extent, due to increases in interest rates.

Interest Income. Interest income decreased to $220 in the first quarter of
fiscal 2000 from $238 in the first quarter of fiscal 1999. This decrease is
attributable to lower average cash equivalents and short-term investments in the
first quarter of fiscal 2000 as compared to the first quarter of fiscal 1999.

Income (Loss) from Equity Investments. The income from equity investments in the
first quarter of fiscal 2000 represents $50 of earnings from the Company's
investment in Fiberstars, Inc., a marketer and distributor of fiber optic
lighting products. The loss from equity investments in fiscal 1999 represents
$53 of earnings from the Company's investment in Fiberstars, Inc., offset by a
$242 loss from the Company's investment in Venture Lighting Japan, a
manufacturer and marketer of metal halide lamps in Japan.

Loss from Continuing Operations before Income Taxes. The Company incurred a loss
from continuing operations before income taxes of $564 during the first quarter
of fiscal 2000 as compared to a loss from continuing operations before income
taxes of $845 during the first quarter of fiscal 1999.

Income Taxes. Income tax expense was $218 for the first quarter of fiscal 2000
as compared to an income tax benefit of $174 in the first quarter of fiscal
1999. The income tax expense in the first quarter of fiscal 2000 relates
primarily to certain of the Company's foreign operations.

At June 30, 1999, the Company had net operating loss carryforwards ("NOLs") of
$57,309 available to reduce future United States federal taxable income, which
expire in varying amounts from 2008 to 2019.

The Company also has research and development credit carryforwards for tax
purposes of approximately $3,006, which expire in varying amounts from 2005 to
2019. Additionally, in conjunction with the Alternative Minimum Tax ("AMT")
rules, the Company had available AMT credit carryforwards for tax purposes of
approximately $162, which may be used indefinitely to reduce regular federal
income taxes.

Also at June 30, 1999, the Company had foreign net operating loss carryforwards
for tax purposes totaling $5,209, that expire in varying amounts from 2000 to
2005 and $10,587 that have no expiration dates.

Reclassification of Discontinued Operations to Continuing Operations. See
"Discontinued Operations Subsequently Retained" and Note G of "Notes to
Condensed Consolidated Financial Statements (Unaudited)" for further discussion.

Cumulative Effect of Change in Accounting for Start-Up Costs. During the fourth
quarter of fiscal 1999, the Company adopted Statement of Position ("SOP") 98-5,
"Reporting on the Costs of Start-Up Activities," effective July 1, 1998. The
first quarter of fiscal 1999 has been restated to reflect the cumulative effect
of the accounting change of $2,443.

LIQUIDITY AND CAPITAL RESOURCES

The Company's principal financial requirements are for market development
activities, research and development efforts, investments in business
acquisitions, joint ventures and working capital. These requirements have been,
and the Company expects they will continue to be, financed through a combination
of cash flow from operations, borrowings under various credit facilities and the
sale of stock.

Cash increased $429 during the first quarter of fiscal 2000. Uses of cash
consisted of $4,969 used in operating activities and $1,090 used in investing
activities. These uses of cash were offset by net financing activities of
$6,488.

Net cash used in operating activities. Net cash used in operating activities
totaled $4,969 during the first quarter of fiscal 2000 as compared to $15,093 in
the first quarter of fiscal 1999. The increase in trade receivables of $4,324
accounted for a large part of this usage, and was primarily a result of the
increase in sales. In spite of this usage of cash in the first quarter, the
Company intends to manage its cash resources to generate positive cash flow from
operating activities for the full fiscal year 2000 and beyond.

Net cash used in investment activities. During the first quarter of fiscal 2000,
investing activities used $1,090 of cash, which was primarily represented a
$1,440 usage for capital expenditures offset by a $350 source of funds from the
sale of a short-term investment.

Capital expenditures, primarily for production equipment and leasehold and
facility improvements, totaled $1,440 during the first quarter of fiscal 2000 as
compared to $9,313 during the first quarter of fiscal 1999. Capital expenditures
in fiscal 2000 related to additional machinery and equipment to improve
production processes, which should result in increased productivity and capacity
in the production of lamps, power supplies and other lighting system products.

The Company has modified its current growth and capital expansion plans due to
the present limited availability of cash resources. Specifically, the Company
will limit its capital expenditures for at least the next twelve months and, as
a result, the Company has postponed the acquisition of certain capital equipment
and, for all practical purposes, facilities expenditures have been completed.


                                       22
<PAGE>   24


As a result of the Company's decision to terminate joint venture equipment
contracts in the quarter ended December 31, 1998, approximately $6,500 of new
production equipment is available for installation at the Company's Solon, Ohio
lamp manufacturing facility. The Company estimates its maintenance level for
capital expenditures will approximate $6,000 to $8,000 over the next twelve
months. Future capital expenditures beyond this level will be discretionary, as
the Company presently has sufficient operating capacities to support several
years of sales growth at its historical rates.

To expand the Company's ability to develop and market new metal halide products
and systems, the Company has made a number of acquisitions and strategic
investments, the most notable of which, completed in January 1998, are described
below.

On January 28, 1998, the Company completed the acquisition of Deposition
Sciences, Inc. ("DSI"), of Santa Rosa, California. DSI is a leader in the
development of sophisticated thin film deposition systems and coatings for
lighting applications, with particular emphasis on coatings for metal halide
lighting systems, and other applications, including aerospace, defense and
automotive applications. The stock of DSI was acquired in a privately-negotiated
transaction. The purchase price consisted of 599,717 shares of the Company's
Common Stock and approximately $14,500 in cash.

On January 2, 1998, the Company acquired all of the capital stock outstanding of
Ruud Lighting (the "Ruud Stock"), located in Racine, Wisconsin. Ruud Lighting
manufactures and directly markets HID lighting systems, principally focusing on
metal halide installations for commercial, industrial and outdoor lighting
applications. The Ruud Stock was acquired from the five shareholders of Ruud
Lighting in a privately negotiated purchase transaction. The purchase price for
the Ruud Stock consisted of three million shares of the Company's Common Stock
and approximately $35,500 in cash.

Net cash provided by financing activities. During the first quarter of fiscal
2000, net financing activities provided cash of $6,488, which included $7,663 of
cash provided from net borrowings under the Company's revolving credit
facilities, net of repayments of long-term debt and capital leases of $1,320.

On March 13, 1998, the Company sold $100,000 of 8% Senior Notes due March 15,
2008, resulting in net proceeds of $96,150. Approximately $76,300 of the net
proceeds of the Senior Notes were used to repay amounts outstanding under the
Credit Facility, thereby lengthening the average term of the Company's debt,
most of which had been incurred to finance the acquisitions of Ruud Lighting and
DSI. From September 14, 1998 until completion of a registered exchange offer to
existing noteholders, the Senior Notes bear interest at 8.5%. The offer is
expected to be completed within 45 days following effectiveness of the Company's
related registration statement.

Pursuant to a loan agreement dated October 8, 1998, between the Company and its
Chairman and Chief Executive Officer (the "CEO"), the Company has loaned $9,000
to its CEO for a one-year term at an interest rate of 8%. The loan was made
following approval by the Company's Board of Directors. The proceeds of the loan
were used by the Company's CEO to reduce the principal balance outstanding of a
margin account loan, which is secured by 2,053,070 shares of the


                                       23
<PAGE>   25


Company's Common Stock owned by the CEO and a related entity. In connection with
the loan, the Company's Board of Directors asked for and received the CEO's
agreement to extend the term of his employment agreement to December 31, 2003.
The loan agreement prohibits the CEO from encumbering his shares of the
Company's Common Stock in any manner except pursuant to the existing agreements
governing the CEO's margin account, without the consent of the Company's Board
of Directors.

The CEO has paid accrued interest of $720 on the loan through October 6, 1999.
The principal on the loan was due on October 6, 1999. Members of the Board of
Directors and the CEO are discussing alternative payment terms which will
achieve the Board's original business objectives in making the loan and meet the
Company's current business needs. The Directors and the CEO believe that these
discussions will be completed by January 2000. The Board has informed the CEO
that the Company may require immediate payment during these discussions if the
Company requires the payment to prevent an unacceptable strain on cash
resources.

Ability to advance future operations. The Company has begun to implement, and
will continue to implement, changes in its operations and investment activities
intended to reduce the use of its cash resources to a level at or below the cash
flow generated by its operations and investments.

The Company's working capital (current assets less current liabilities) at
September 30, 1999 was $25,737, resulting in a working capital ratio of current
assets to current liabilities of 1.5 to 1.0, as compared to $18,629 or 1.3 to
1.0 at June 30, 1999. As of September 30, 1999, the Company had $4,259 in cash
and cash equivalents.

The interest-bearing obligations of the Company totaled $167,427 as of September
30, 1999, and consisted of: $44,239 of borrowings under the Bank Credit
Facility; $100,000 of 8% Senior Notes; mortgages of $16,915; a promissory note
due to an affiliate of $3,000; borrowings of a foreign subsidiary of $1,715;
capital leases of $1,547; and, other obligations of $11.

In May 1999, the Company replaced its existing Credit Facility with a $50,000
revolving credit loan and $25,000 term loan provided by several financial
institutions. Subsequent to June 30, 1999 the Company reduced its commitment to
a $40,000 revolver and $20,000 term loan. Proceeds from the facility were used
to repay the Company's existing credit facility and certain other long-term
debt. The revolving credit loan has a three-year term expiring in May 2002.
Interest rates on loans outstanding are based, at the Company's option, on LIBOR
plus 2.75% or the agent bank's prime rate. Availability of borrowings is
determined by the Company's eligible accounts receivable and inventories.
Following the GE investment on October 6, 1999, after the proceeds were applied
to reduce the term loan to $20,000 under the Bank Credit Facility and apply the
remainder of the proceeds to reduce the revolving credit loan. The term loan has
a five-year term expiring in May 2004. The Company pays monthly principal
payments of $298, with the unpaid balance due at maturity. Interest rates on the
term loan are based, at the Company's option, on LIBOR plus 3.25% or the agent
bank's prime rate.

The Bank Credit Facility contains certain affirmative and negative covenants
customary for this type of agreement, prohibits cash dividends, and includes
financial covenants with respect to the coverage of certain fixed charges. The
principal security for the revolving credit loan is


                                       24
<PAGE>   26


substantially all of the personal property of the Company and each of its North
American and United Kingdom subsidiaries. The term loan is secured by
substantially all of the Company's machinery and equipment and is
cross-collateralized and secured with the revolving credit loan.

The Company's implementation of the cost reduction and cash flow enhancement
initiatives including consolidation of equipment and lamp-making operations,
reductions in capital expenditures, consolidation of international operations,
reduction of corporate expenses, and overall workforce reductions should
favorably impact the future cash flow of the Company. The Company intends to
manage its expenditures to generate positive cash flow in fiscal 2000 and
beyond.

The Company believes that the available cash, cash flow from operations, and the
initiatives outlined above, along with availability of approximately $15,000
under its existing Bank Credit Facility after giving effect to the GE
investment, will enable the Company to fund its operations for at least the next
12 months.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

The Company has not yet adopted FAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." FAS 133 requires that all derivatives, such
as interest rate exchange agreements (swaps), be recognized on the balance sheet
at fair value. Derivatives which are not hedges must be adjusted to fair value
through the results of operations. Derivatives determined to be hedges will be
adjusted to fair value through either the results of operations or other
comprehensive income, depending on the nature of the hedge. The Company is
required to adopt FAS No. 133, as subsequently amended by FAS No. 137, on July
1, 2000. The impact, if any, on net income, comprehensive income and financial
position will depend on the amount, timing and nature of any agreements entered
into by the Company.

YEAR 2000 READINESS

State of Readiness. During the past three fiscal years, the Company has been
actively involved in finding and correcting the Year 2000 problems within its
information technology structure. The information system correction process is
essentially complete. The Company maintains its critical information technology
systems in close cooperation with its suppliers. The Company is not currently
operating any legacy systems that are no longer being supported by the original
supplier.

The most critical noninformation technology systems, such as robots and other
numerically controlled equipment, are relatively new and are being upgraded and
maintained with the help of the Company's various suppliers. To date, the
Company's investigation of these systems has revealed only minor Year 2000
problems which were quickly corrected and the Company does not expect to find
any further problems.

Each operating unit's purchasing and production control departments are in the
process of analyzing the unit's key third-party dependencies and working with
each of these key suppliers to determine the suppliers' Year 2000 status.
The Company has had reasonable success in


                                       25
<PAGE>   27


obtaining reliable Year 2000 compliance certifications. The Company continues to
be concerned with the potential loss of energy (electricity and natural gas) at
its facilities worldwide, with the most vulnerable facilities presently
preparing contingency plans to protect their plant and equipment.

Costs. The Company has had only limited expenditures related to Year 2000
issues, consisting principally of personnel costs incurred in the scope of
normal operations. In addition, software replacements and upgrades in the
ordinary course of business have enhanced the Company's Year 2000 readiness
without incremental costs. The Company is in the final stages of its projects
and does not anticipate that future Year 2000 costs related to information
technology operations will be significantly beyond the scope of normal
operations.

The Company is in the process of implementing contingency plans to protect it
from Year 2000 failures. These plans are mostly complete and will result in
limited additional expenditures. Primarily these expenditures have been in the
form of increased inventory and the addition of some generating and auxiliary
heating equipment to protect facilities.The Company anticipates that additional
total costs will not have a material impact on the ongoing results of
operations.

Risks. In the early weeks of 2000, the Company may experience some random supply
chain disruptions that may affect its ability to produce and distribute key
products. These disruptions will be material if the United States experiences
significant interruptions in basic services, such as the electric power grid,
natural gas, telephone service or the banking systems. And while recent data on
the readiness of the electric power utilites have been increasingly more
positive, the Company's highest level of contingency planning is being focused
in this area.

Contingency Plans. The Company, through its various purchasing and production
control departments, is in the process of developing contingency plans at each
of its worldwide operations. These plans will be particularly focused on
preparing the operation for the inability of key third-party suppliers to
perform their normal functions. Of critical importance will be the development
of alternative suppliers, the enhancements of on-hand materials and the
augmentation of the most critical finished goods. Facilities in very cold
climates are preparing to minimize the potential effects of the loss of
electricity.

Completion. Based on management's assessment of current progress, the Company
believes it will complete the limited amount of Year 2000 modifications and
contingency plans that remain before the end of 1999. The Company is in close
contact with its key hardware and software suppliers, and will implement any
future updates shortly after they are released.The Company can give no assurance
that the Company's Year 2000 preparations will prevent disruptions in its
business resulting from Year 2000 problems of the Company, its suppliers or its
customers, or that costs to the Company of its preparations or any disruptions
will not be material.

FOREIGN CURRENCY

Approximately 34% of the Company's net sales in fiscal 1999, were denominated in
currencies other than U.S. dollars, principally Pounds Sterling, Australian
dollars and Canadian dollars. A weakening of such currencies versus the U.S.
dollar could have a material adverse effect on the Company. The Company
currently does not hedge its foreign currency exposure.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

During the three months ended September 30, 1999, there have been no material
changes in the reported market risks presented in the Company's Annual Report on
Form 10-K for the year ended June 30, 1999.

PART II. OTHER INFORMATION

Except as noted below, the items in Part II are inapplicable or, if applicable,
would be answered in the negative. These items have been omitted and no other
reference is made thereto.

ITEM 5. OTHER INFORMATION

(a) As previously reported, pursuant to a loan agreement dated October 8, 1998,
between the Company and Mr. Hellman, its Chairman and Chief Executive Officer
(the "Hellman Loan Agreement"), the Company has loaned $9,000,000 to Mr. Hellman
for a one-year term at the rate of 8%. The loan was made following approval by
the Company's Board of Directors (Messrs. Hellman and Fisi, Executive Vice
President and a director of the Company, did not participate in the
deliberations). The proceeds of the loan were used to reduce the outstanding
principal balance of a loan from Prudential Securities Incorporated ("PSI"),
which is secured by 2,053,070 shares of the Company Common Stock owned by Mr.
Hellman and Hellman Ltd. (the "Hellman Personal Shares"). In connection with the
loan, the Board asked for and received Mr. Hellman's agreement to extend the
term of his employment agreement to December 31, 2003. The Hellman Loan
Agreement prohibits Mr. Hellman from encumbering the Hellman Personal Shares in
any manner except pursuant to existing agreements governing Mr. Hellman's margin
account at PSI, without consent of the Board's representative.

The CEO has paid accrued interest of $720,000 on the loan through October 6,
1999. The principal on the loan was due on October 6, 1999. Members of the Board
of Directors and the CEO are discussing alternative payment terms which will
achieve the Board's original business objectives in making the loan and meet the
Company's current business needs. The Directors and the CEO believe that these
discussions will be completed by January 2000. The Board has informed the CEO
that the Company may require immediate payment during these discussions if the
Company requires the payment to prevent an unacceptable strain on cash
resources.

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

receive, prior and in preference to any distribution




                                    Page 5
<PAGE>   7




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>   8

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

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

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

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

        (b) RESERVATION OF COMMON SHARES. The Corporation shall at all times
reserve and keep available out of its authorized but unissued Common Shares,
solely for the purpose of issuance upon the conversion of the Series A
Preferred Shares, such number of Common Shares issuable upon the conversion of
all outstanding Series A Preferred Shares. All Common Shares which are so
issuable shall, when issued, be duly and validly issued, fully paid and
nonassessable and free from all taxes, liens and charges. The Corporation shall
take all such actions as may be necessary to assure that all such Common Shares
may be so issued without violation of any applicable law or governmental
regulation or any requirements of any domestic securities exchange upon which
Common Shares may be listed (except for official notice of issuance which shall
be immediately delivered by the Corporation upon each such issuance).

        (c) ADJUSTMENTS. Subject to NASDAQ Approval, the following adjustments
shall apply as set forth in this Section V. The Corporation shall give each
holder of Preferred Shares notice of any event described below in accordance
with Section V(d) below.

                (i) SHARE DIVIDENDS, SUBDIVISIONS AND COMBINATIONS. If at any
time the Corporation shall:


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

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

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

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

                (ii) CERTAIN OTHER DISTRIBUTIONS AND ADJUSTMENTS.


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

                                          (1) cash,


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

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

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


                                (B) A reclassification of the Common Shares
                (other than a change in par value, or from par value to no par
                value or from no par value to par value) into



                                    Page 8
<PAGE>   10

                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>   11

              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>   12

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>   13

         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.

<PAGE>   14

                           (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>   15

         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>   16

Shares or other stock into which the Series A Preferred Shares are convertible
shall be adjusted in such manner as may be equitable in the circumstances.

         (d)      NOTICES TO HOLDERS OF SERIES A PREFERRED SHARES.

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

                  (ii)     NOTICE OF CORPORATE ACTION.  If at any time:

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

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

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

then, in any one or more of such cases, the Corporation shall give to each
holder of Series A Preferred Shares (A) at least 30 days prior written notice of
the date on which a record date shall be selected for such dividend,
distribution or right or for determining rights to vote in respect of any such
reorganization, reclassification, merger, consolidation, sale, transfer,
disposition, dissolution, liquidation or winding up, and (B) in the case of any
such reorganization, reclassification, merger, consolidation, sale, transfer,
disposition, dissolution, liquidation or winding up, at least 30 days prior
written notice of the date when the same shall take place. Such notice in
accordance with the foregoing clause also shall specify (A) the date on which
any such



                                    Page 15
<PAGE>   17

record is to be taken for the purpose of such dividend, distribution or right,
the date on which the holders of Common Shares shall be entitled to any such
dividend, distribution or right, and the amount and character thereof, and (B)
the date on which any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, dissolution, liquidation or winding
up is to take place and the time, if any such time is to be fixed, as of which
the holders of Common Shares shall be entitled to exchange their Common Shares
for securities or other property deliverable upon such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up. Each such written notice shall be
sufficiently given if addressed to each holder of Series A Preferred Shares at
the last address of such holder appearing on the books of the Corporation.

VI.      REDEMPTION OF SERIES A PREFERRED SHARES.

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

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

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

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




                                    Page 16
<PAGE>   18

                  (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>   19

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>   20

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

Section VII.

                                    Page 19

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

Registrable Securities when they have been distributed to the public pursuant to
an offering registered under the Securities Act or sold to the public through a
broker, dealer or market maker in compliance with Rule 144 (or any similar rule
then in force). For purposes of this Agreement, a Person shall be deemed to be a

                  2. DEMAND REGISTRATIONS.

                  (a) REQUESTS FOR REGISTRATION. Subject to the terms and
conditions hereof, if the holders of Registrable Securities representing at
least either (i) an aggregate of 30% of the total of all Registrable Securities,
or (ii) Registrable Securities having a minimum anticipated aggregate offering
price of at least $7,500,000, request registration under the Securities Act of
any of their Registrable Securities on Form S-1 or any similar long-form
registration ("Long-Form Registrations") or, as provided in Section 2(c), the
holders of Registrable Securities request registration under the Securities Act
of all or part of their Registrable Securities on Form S-2 or S-3 or any similar
short-form registration ("Short-Form

                                       2
<PAGE>   3


Registrations"), if available, which requests specify the approximate number of
Registrable Securities requested to be registered and the anticipated per share
price range for such offering, then within ten days after receipt of any such
request, the Company shall give written notice of such requested registration to
all other holders of Registrable Securities and shall include in the
registration all Registrable Securities with respect to which the Company has
received written requests for inclusion therein within 15 days after the receipt
of the Company's notice. All registrations requested pursuant to this Section
2(a) are referred to herein as "Demand Registrations."

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

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

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

                  (e) RESTRICTIONS ON REGISTRATIONS. The Company shall not be
obligated to effect any Demand Registration within six months after the
effective date of a previous Demand Registration or a registration in which the
holders of Registrable Securities were given piggyback rights pursuant to
Section 3 and in which there was no reduction in the number of Registrable
Securities requested to be included (except to the extent permitted pursuant to
Section 2(b) with respect to a Long-Form Registration). The Company may postpone
for up to six months the filing or the effectiveness of a registration statement
for a Demand Registration if the Board of Directors of the Company determines in
good faith that it is reasonably foreseeable that the Demand Registration would
reasonably be expected to have a material adverse effect on any proposal or plan
by the Company to engage in any acquisition of assets (other than in the
ordinary course of business) or any merger, consolidation, tender offer or
similar transaction; provided, that, in such event, the holders of Registrable
Securities initially requesting the Demand Registration shall be entitled to
withdraw such request and, if such request is withdrawn, the Demand Registration
shall not count as the one (1) permitted Long-Form Registration hereunder, and
the Company shall pay all Registration Expenses in connection with the withdrawn
registration.

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

                  3. PIGGYBACK REGISTRATIONS.

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

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

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

                                       4

<PAGE>   5

                  (d) PRIORITY ON SECONDARY REGISTRATIONS. If a Piggyback
Registration is an underwritten secondary registration on behalf of holders of
the Company's securities and the managing underwriters advise the Company in
writing that, in their opinion, the number of securities requested to be
included in the registration exceeds the number which can be sold in an orderly
manner in such offering within a price range acceptable to the holders initially
requesting the registration, subject to the Third Party Registration Rights, the
Company shall include in such registration (i) first, the Registrable Securities
requested to be included in the registration, pro rata among the holders of such
Registrable Securities on the basis of the number of shares owned by each
holder, and (ii) second, other securities requested to be included in such
registration.

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

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

                  4. HOLDBACK AGREEMENTS.

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

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

                                       5
<PAGE>   6

during such period (except as part of such underwritten registration, if
otherwise permitted), unless the underwriters managing the registered public
offering otherwise agree.

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

                  (a) Prepare and file with the Commission a registration
statement with respect to such Registrable Securities and use its best efforts
to cause the registration statement to become effective and remain effective
until the earlier of (i) the date when all Registrable Securities covered by the
registration statement have been sold, or (ii) 180 days from the effective date
of the registration statement; provided that before filing a registration
statement or prospectus or any amendments or supplements thereto, the Company
shall furnish to the counsel selected by the holders of a majority of the
Registrable Securities covered by the registration statement copies of all such
documents proposed to be filed, including documents that are to be incorporated
by reference into the registration statement, amendment or supplement, which
documents shall be subject to the review of such counsel, and which proposed
registration statement or amendment or supplement thereto shall not be filed by
the Company if the holders of a majority of the Registrable Securities covered
by the registration statement, amendment or supplement reasonably object to such
filing;

                  (b) Prepare and file with the Commission such amendments and
supplements to the registration statement and the prospectus used in connection
therewith as may be necessary to keep the registration statement effective for
the period referred to in Section 5(a) and comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by the
registration statement during such period in accordance with the intended
methods of disposition by the sellers thereof set forth in the registration
statement;

                  (c) Furnish to each seller of Registrable Securities such
number of copies of the registration statement, each amendment and supplement
thereto, the prospectus included in the registration statement (including each
preliminary prospectus) and such other documents as such holder may reasonably
request in order to facilitate the disposition of the Registrable Securities
owned by such holder;

                  (d) Use its best efforts to register or qualify such
Registrable Securities under such other securities or blue sky laws of such
jurisdictions as any holder thereof reasonably requests and do any and all other
acts and things which may be reasonably necessary or advisable to enable such
holder to consummate the disposition in such jurisdictions of the Registrable
Securities owned by such holder;

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

                                       6
<PAGE>   7

or amendment to the prospectus so that, as thereafter delivered to the
purchasers of such Registrable Securities, such prospectus shall not contain an
untrue statement of a material fact or omit to state any fact necessary to make
the statements therein not misleading;

                  (f) Promptly notify the holders of Registrable Securities and
the underwriters, if any, of the following events and (if requested by any such
Persons) confirm such notification in writing: (i) the filing of the prospectus
or any prospectus supplement and the registration statement and any amendment or
post-effective amendment thereto and, with respect to the registration statement
or any post-effective amendment thereto, the declaration of the effectiveness of
such document; (ii) any requests by the Commission for amendments or supplements
to the registration statement or the prospectus or for additional information;
(iii) the issuance or threat of issuance by the Commission of any stop order
suspending the effectiveness of the registration statement or the initiation of
any proceedings for that purpose; and (iv) the receipt by the Company of any
notification with respect to the suspension of the qualification of the
Registrable Securities for sale in any jurisdiction or the initiation or threat
of initiation of any proceeding for such purpose;

                  (g) Cause all such Registrable Securities to be listed on each
securities exchange on which similar securities issued by the Company are then
listed and, if not so listed, to be listed on the NASD automated quotation
system and, if listed on the NASD automated quotation system, endeavor to secure
designation of all such Registrable Securities covered by the registration
statement as a NASDAQ "national market system security" within the meaning of
Rule 11Aa2-1 of the Commission or, failing that, to secure NASDAQ authorization
for such Registrable Securities and, without limiting the generality of the
foregoing, to arrange for at least two market makers to register as such with
respect to such Registrable Securities with the NASD;

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

                  (i) Enter into such customary agreements (including, without
limitation, underwriting agreements in customary form) and take all such other
actions as the holders of a majority of the Registrable Securities being sold or
the underwriters, if any, reasonably request in order to expedite or facilitate
the disposition of such Registrable Securities (including, without limitation,
effecting a stock split or a combination of shares);

                  (j) Make available for inspection by any holder of Registrable
Securities, any underwriter participating in any disposition pursuant to the
registration statement and any attorney, accountant or other agent retained by
any such holder or underwriter, all financial and other records, pertinent
corporate documents and properties of the Company, and cause the Company's
officers, directors, employees and independent accountants to supply all
information reasonably requested by any such holder, underwriter, attorney,
accountant or agent in connection with the registration statement;

                  (k) Otherwise endeavor to comply with all applicable rules and
regulations of the Commission, and make available to its security holders, as
soon as reasonably practicable, an earnings statement covering the period of at
least twelve months beginning with the first day of

                                       7
<PAGE>   8

the Company's first full calendar quarter after the effective date of the
registration statement, which earnings statement shall satisfy the provisions of
Section 11(a) of the Securities Act and Rule 158 thereunder;

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

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

                  (n) Use its best efforts to cause such Registrable Securities
covered by the registration statement to be registered with or approved by such
other governmental agencies or authorities as may be necessary to enable the
holders thereof to consummate the disposition of such Registrable Securities;

                  (o) Cooperate with the selling holders of Registrable
Securities and the underwriters, if any, to facilitate the timely preparation
and delivery of certificates representing Registrable Securities to be sold and
not bearing any restrictive legends, and enable such Registrable Securities to
be in such lots and registered in such names as the underwriters may request at
least two business days prior to any delivery of Registrable Securities to the
underwriters;

                  (p) Provide a CUSIP number for all Registrable Securities not
later than the effective date of the registration statement; and

                  (q) Prior to the effectiveness of the registration statement
and any post-effective amendment thereto and at each closing of an underwritten
offering, (i) make such representations and warranties to the selling holders of
such Registrable Securities and the underwriters, if any, with respect to the
Registrable Securities and the registration statement as are customarily made by
issuers to underwriters in primary underwritten offerings, (ii) obtain opinions
of counsel to the Company and updates thereof (which counsel and which opinions
shall be reasonably satisfactory to the underwriters, if any, and to the holders
of a majority of the Registrable Securities being sold) addressed to each
selling holder and the underwriters, if any, covering the matters customarily
covered in opinions requested in underwritten offerings and such other matters
as may be reasonably requested by such holders and underwriters or their
counsel, (iii) obtain "cold comfort" letters and updates thereof from the
Company's independent certified public accountants addressed to the selling
holders of Registrable Securities and the underwriters, if any, such letters to
be in customary form and covering matters of the type customarily covered in
"cold comfort" letters by underwriters in connection with primary underwritten
offerings, and (iv) deliver such documents and certificates as may be reasonably
requested by the holders of a majority of the Registrable Securities being sold
and by the

                                       8
<PAGE>   9

underwriters, if any, to evidence compliance with clause (i) above and with any
customary conditions contained in the underwriting agreement or other agreement
entered into by the Company.

                  6. REGISTRATION EXPENSES.

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

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

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

                  7. INDEMNIFICATION.

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

                                       9
<PAGE>   10


                  (b) In connection with any registration statement in which a
holder of Registrable Securities is participating, each holder shall furnish to
the Company in writing such information and affidavits as the Company reasonably
requests for use in connection with any such registration statement or
prospectus and, to the extent permitted by law, shall indemnify the Company, its
directors and officers and each Person who controls the Company (within the
meaning of the Securities Act) against any losses, claims, damages, liabilities
and expenses resulting from any untrue or alleged untrue statement of material
fact contained in the registration statement, prospectus or preliminary
prospectus or any amendment thereof or supplement thereto or any omission or
alleged omission of a material fact required to be stated therein or necessary
to make the statements therein not misleading, but only to the extent that such
untrue statement or omission is contained in any information or affidavit so
furnished in writing by the holder; provided that the obligation to indemnify
shall be individual to each holder and shall be limited to the net amount of
proceeds received by the holder from the sale of Registrable Securities pursuant
to the registration statement.

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

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

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

                                       10

<PAGE>   11

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

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

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

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

                  10. CERTAIN LIMITATIONS IN CONNECTION WITH FUTURE GRANTS OF
REGISTRATION RIGHTS. From and after the date of this Agreement, the Company
shall not enter into any agreement with any holder or prospective holder of any
securities of the Company providing for the granting to the holder of
registration rights unless the agreement:

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

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

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

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

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

                                       11
<PAGE>   12

                  12. MISCELLANEOUS.

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

                  (b) ADJUSTMENTS AFFECTING REGISTRABLE SECURITIES. The Company
shall not take any action, or permit any change to occur, with respect to its
securities which would materially and adversely affect the ability of the
holders of Registrable Securities to include such Registrable Securities in a
registration undertaken pursuant to this Agreement or which would materially and
adversely affect the marketability of such Registrable Securities in any such
registration (including, without limitation, effecting a stock split or a
combination of shares).

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

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

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

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

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

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

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

                  (j) NOTICES. All notices, demands or other communications to

RE:      CREDIT AGREEMENT DATED AS OF MAY 21, 1999 AMONG ADVANCED LIGHTING
         TECHNOLOGIES, INC., AS U.S. BORROWER, BALLASTRONIX INCORPORATED (KNA
         VENTURE LIGHTING POWER SYSTEMS, NORTH AMERICA INC.) AND CANADIAN
         LIGHTING SYSTEMS HOLDING, INCORPORATED, AS CANADIAN BORROWERS, PARRY
         POWER SYSTEMS LIMITED AND VENTURE LIGHTING EUROPE LTD., AS UK
         BORROWERS, VARIOUS FINANCIAL INSTITUTIONS, AS BANKS, AND PNC BANK,
         NATIONAL ASSOCIATION, AS AGENT (THE "CREDIT AGREEMENT") (CAPITALIZED
         TERMS USED IN THIS LETTER WITHOUT DEFINITION HAVE THE MEANINGS ASCRIBED
         THERETO IN THE CREDIT AGREEMENT)

Ladies and Gentlemen:

In connection with BankBoston, N.A. ("BankBoston") entering into that certain
Assignment and Acceptance Agreement pursuant to which it agrees to become a
"Bank" under the Credit Agreement, as more fully set forth in the Assignment and
Acceptance Agreement, PNC Bank, National Association, as Agent ("Agent") and
BankBoston hereby agree as follows:

1.       The definition "Required Banks" contained in Article I of the Credit
         Agreement shall be amended (the "Amendment") to mean Agent and at least
         one other Lender (other than PNC Bank, National Association) which has
         a minimum commitment of $10,000,000.

2.       Section 5.3 of the Credit Agreement shall be amended to expressly
         provide for, among other things:

         (a)      the weekly delivery of Borrowers assignment of sales and the
                  monthly delivery of Borrower's Certificate by each Borrower;

         (b)      the delivery on a monthly basis of an accounts receivable
                  aging report and an accounts payable report, to be in form of
                  substance satisfactory to the Agent and the Required Banks;

         (c)      the consent of the Required Banks for any amendment to the
                  Indenture, namely that the definition of Indenture contained
                  in the Credit Agreement will be modified in the third line
                  thereof to provide for the "prior written consent of the
                  Required Banks"; and


<PAGE>   2

         (d)      the modification of the definition of "Total Unused Credit
                  Availability" contained in Article I of the Credit Agreement
                  to read in its entirety as follows: "Total Unused Credit
                  Availability" shall mean, at any time, the difference between
                  (a) the sum of (i) the U.S. Borrowing Base, (ii) the UK
                  Borrowing Base and (iii) the Canadian Borrowing Base, minus
                  (b) the Revolving Credit Exposure."

3.       The Canadian Credit Facility set forth in Section 2.1.A.3 of the Credit
         Agreement will be modified under the terms of the Amendment to provide
         that:

         (a)      borrowing requests by Canadian Borrowers shall request Loans
                  from the Banks in Dollars;

         (b)      Loans from the Banks to Canadian Borrowers will be made in
                  Dollars; and

         (c)      the repayment of Loans made by the Banks to the Canadian
                  Borrowers will be repaid in Dollars.

         The Credit Agreement, the Canadian Revolving Credit Notes and the other
         Related Writings, as applicable, will be modified to reflect the
         foregoing in a manner satisfactory to Agent and the Banks.

4.       Until such time as the Credit Agreement and Related Writings are
         modified to reflect the provisions of Paragraphs 3 and 5 herein, no
         Loans will be made under Canadian Revolving Credit Commitment. In lieu
         thereof, to the extent that there is availability under the U.S.
         Borrowing Base, U.S. Borrower may request U.S. Revolving Loans and
         advance funds by way of intercompany loans to the Canadian Borrowers as
         permitted by the Credit Agreement.

5.       The Amendment will provide for the deletion of Section 2.5(e)(ii)(C)
         and (D). The Amendment will further provide for the deletion of the
         second paragraph under Section 3.2 of the Credit Agreement, and the
         addition in place thereof of provisions that will provide that if the
         Borrower pays any additional amount under Section 3.2 to a Bank and
         such Bank determines in its sole discretion that it has actually
         received or realized in connection therewith any refund or any
         reduction of, or credit against, its tax liabilities in or with respect
         to the taxable year in which the additional amount is paid, such Bank
         shall pay to such Borrower an amount that the Bank shall, in its sole
         discretion, determine is equal to the net benefit, after tax, which was
         obtained by the Bank in such year as a consequence of such tax benefit;
         provided, however, that any Bank may determine in its sole discretion
         consistent with the policies of such Bank whether to seek a tax
         benefit, and nothing in Section 3.2 shall require a Bank to disclose
         any confidential information to any Borrower (including, without
         limitation, its tax returns). Additionally, in connection with Canadian
         Borrowers' withholding tax liability with respect to Canadian Revolving
         Loans, the Amendment will contain provisions specifically stating that
         (a) Canadian Borrowers are responsible for the timely payment of all
         withholding taxes, (b) evidence of the making of those payments in a
         timely manner, and (c) Banks and Agent will be indemnified for any loss
         or liability resulting from Canadian Borrowers' failure to make such
         tax payments in a timely manner.

6.       Notwithstanding the provisions of Section 10.3 of the Credit Agreement
         or the definition of "Required Lenders", the Amendment and any related
         changes to the Related Writings shall be in a form and substance
         satisfactory to Borrower, Agent, BankBoston and any other Banks and
         shall address such other matter as are deemed necessary or appropriate
         by Agent and the Banks. The parties hereto will use their good faith
         efforts to enter into the Amendment no later than August 25, 1999.

The undersigned agree to and acknowledge the foregoing terms, provisions and
conditions of this letter.

         2. ASSIGNMENT AND ASSUMPTION. Assignor hereby sells and assigns to
Assignee, and Assignee hereby purchases and assumes from Assignor, an interest
in and to Assignor's rights and obligations under the Credit Agreement,

         4. PAYMENT OBLIGATIONS. In consideration for the sale and assignment of
Loans hereunder, Assignee shall pay Assignor, on the Assignment Effective Date,

which it may receive promptly upon receipt thereof.

         5. CREDIT DETERMINATION; LIMITATIONS ON ASSIGNOR'S LIABILITY. Assignee
represents and warrants to Assignor, Borrowers, Agent and the other Banks (a)

that it meets the requirements to be an assignee as set forth in Section 10.10
of the Credit Agreement; (c) Assignee confirms that it is able to fund the Loans
and the Letters of Credit as required by the Credit Agreement; and (d) Assignee
agrees that it will perform in accordance with their terms all of the
obligations which by the terms of the Credit Agreement and the Related Writings

Credit Agreement is modified pursuant to the side letter among Borrowers, Agent
and Assignee dated the date hereof (the "Side Letter") and the related Amendment
(as defined in the Side Letter) to the Credit Agreement. It is understood and
agreed that (a) the assignment and assumption hereunder are made without
recourse to Assignor, (b) Assignor makes no representation or warranty of any
kind to Assignee except that (i) Assignor has not received notice from any
Borrower that an Event of Default (as defined in the Credit Agreement) has
occurred and (ii) Assignor has the ability to assign hereunder, and (c) Assignor
shall not be responsible for (i) the due execution, legality, validity,

statement made in or in connection with the Credit Agreement or any of the
Related Writings, (iii) the financial condition or creditworthiness of any
Borrower or any Guarantor, (iv) the performance of or compliance with any of the
terms or provisions of the Credit Agreement or any of the Related Writings, (v)
inspecting any of the property, books or records of any Borrower, or (vi) the
validity, enforceability, perfection, priority, condition, value or sufficiency
of any collateral securing or purporting to secure the Loans or Letters of
Credit. Neither Assignor nor any of its officers, directors, employees, agents
or attorneys shall be liable for any mistake, error of judgment, or action taken
or omitted to be taken in connection with the Loans, the Letters of Credit, the
Credit Agreement or the Related Writings, except for its or their own bad faith
or willful misconduct. Assignee appoints Agent to take such action as agent on
its behalf and to exercise such powers under the Credit Agreement as are
delegated to Agent by the terms thereof.

arising in any manner from Assignee's performance or non-performance of
obligations assumed under this Assignment Agreement.

         7. SUBSEQUENT ASSIGNMENTS. After the Assignment Effective Date,
Assignee shall have the right pursuant to Section 10.10 of the Credit Agreement
to assign the rights which are assigned to Assignee hereunder, provided that (a)
any such subsequent assignment does not violate any of the terms and conditions
of the Credit Agreement, any of the Related Writings, or any law, rule,
regulation, order, writ, judgment, injunction or decree and that any consent
required under the terms of the Credit Agreement or any of the Related Writings
has been obtained, (b) the assignee under such assignment from Assignee shall
agree to assume all of Assignee's obligations hereunder in a manner satisfactory
to Assignor and (c) Assignee is not thereby released from any of its obligations
to Assignor hereunder.

assigned to Assignee shall remain the percentage specified in Section 1 hereof
and the dollar amount of the Commitment of Assignee shall be recalculated based
on the reduced Total Commitment Amount.

         9. ACCEPTANCE OF AGENT; NOTICE BY ASSIGNOR. This Assignment Agreement
is conditioned upon the acceptance and consent of Agent and, if necessary
pursuant to Section 10.10A of the Credit Agreement, upon the acceptance and
consent of Borrowers; provided, that the execution of this Assignment Agreement
by Agent and, if necessary, by Borrowers is evidence of such acceptance and
consent.

         10. ENTIRE AGREEMENT. This Assignment Agreement embodies the entire
agreement and understanding between the parties hereto and supersede all prior
agreements and understandings between the parties hereto relating to the subject
matter hereof.

         11. GOVERNING LAW. This Assignment Agreement shall be governed by the

         3.       Canadian Credit Facility.

         (a)      Canadian Revolving Loans.

                  Subject to the terms and conditions of this Agreement, during
         the Commitment Period (but subject to Section 2.11 hereof), the
         Canadian Banks shall make a Canadian Revolving Loan or Canadian
         Revolving Loans to Canadian Borrowers in such amount or amounts as
         Canadian Borrowers may from time to time request. Canadian Borrowers
         shall not request a Canadian Revolving Loan (and the Canadian Banks
         shall not be obligated to make a Canadian Revolving Loan) if, after
         giving effect thereto, (a) the Canadian Exposure would exceed the
         Canadian Revolving Credit Commitment, or (b) the sum of (i) the UK
         Exposure, (ii) the U.S. Revolving Exposure, (iii) the Canadian Exposure
         and (iv) the U.S. Letter of Credit Exposure would exceed the Maximum
         Revolving Credit Commitment Amount.

                  Canadian Borrowers shall have the option, subject to the terms
         and conditions set forth herein, to borrow Canadian Revolving Loans,
         maturing on the last day of the Commitment Period, by means of any
         combination of (a) Canadian Base Rate Loans, or (b) Canadian Fixed Rate
         Loans.

                                        4

<PAGE>   5



                  Canadian Borrowers shall pay interest on the unpaid principal
         amount of Canadian Base Rate Loans outstanding from time to time from
         the date thereof until paid at the Base Rate from time to time in
         effect. Interest on such Canadian Base Rate Loans shall be payable,
         commencing June 1, 1999, and on the 1st day of each succeeding month
         thereafter, and at the maturity thereof.

                  Canadian Borrowers shall pay interest on the unpaid principal
         amount of each Canadian Fixed Rate Loan outstanding from time to time,
         from the date thereof until paid, at the Derived Eurodollar Rate, fixed
         in advance for each Interest Period as herein provided for each such
         Interest Period. Interest on such Canadian Fixed Rate Loans shall be
         payable on each Interest Adjustment Date with respect to an Interest
         Period (provided that if an Interest Period exceeds three (3) months,
         the interest must be paid every three (3) months, commencing three (3)
         months from the beginning of such Interest Period).

                  At the request of Canadian Borrowers, subject to the notice
         and other provisions of Section 2.2 hereof, the Canadian Banks shall
         convert Canadian Base Rate Loans to Canadian Fixed Rate Loans at any
         time and shall convert Canadian Fixed Rate Loans to Canadian Base Rate
         Loans on any Interest Adjustment Date.

                  The obligation of Canadian Borrowers to repay the Canadian
         Base Rate Loans and the Canadian Fixed Rate Loans made by each Canadian
         Bank and to pay interest thereon shall be evidenced by a Canadian
         Revolving Credit Note of Canadian Borrowers in the form of EXHIBIT C
         hereto, and payable to the order of such Canadian Bank in the principal
         amount of its pro rata share of the Canadian Revolving Credit
         Commitment, or, if less, the aggregate unpaid principal amount of
         Canadian Revolving Loans made hereunder by such Canadian Bank.

                  Subject to the provisions of this Agreement, Canadian
         Borrowers shall be entitled under this subsection 3 of Section 2.1A to
         borrow funds, repay the same in whole or in part and re-borrow
         hereunder at any time and from time to time during the Commitment
         Period.

         (b)      Canadian Letters of Credit.

                  Subject to the terms and conditions of this Agreement, during
         the Commitment Period, such Canadian Bank as shall agree to be the
         Fronting Bank for such Canadian Letter of Credit shall, in its own
         name, but only as agent for the Canadian Banks, issue such Canadian
         Letters of Credit for the account of a Canadian Borrower, as such
         Canadian Borrower may from time to time request. No Canadian Borrower
         shall request any Canadian Letter of Credit (and no Fronting Bank shall
         be obligated to issue any Canadian Letter of Credit) if, after giving
         effect thereto, (i) the Canadian Letter of Credit Exposure would exceed
         the Canadian Letter of Credit Commitment, (ii) the Canadian Exposure
         would exceed the amount of the Canadian Revolving Credit Commitment, or
         (iii) the sum of (A) the Canadian Exposure, (B) the U.S. Revolving
         Exposure, (C) the UK Exposure and (D) the U.S.

                                        5

<PAGE>   6



         Letter of Credit Exposure would exceed the Maximum Revolving Credit
         Commitment Amount. The issuance of each Letter of Credit shall confer
         upon each Canadian Bank the benefits and liabilities of a participation
         consisting of an undivided pro rata interest in the Canadian Letter of
         Credit to the extent of that Canadian Bank's percentage of the Canadian
         Revolving Credit Commitment.

                  Each request for a Canadian Letter of Credit shall be
         delivered to Agent not later than 11:00 A.M. (Cleveland, Ohio time)
         three (3) Business Days prior to the day upon which the Canadian Letter
         of Credit is to be issued. Each such request shall be in a form
         acceptable to Agent and shall specify the face amount thereof, whether
         such Canadian Letter of Credit is a commercial documentary or a standby
         Letter of Credit, the account party, the beneficiary, the intended date
         of issuance, the expiry date thereof, and the nature of the transaction
         to be supported thereby. Concurrently with each such request, the
         Canadian Borrower for whose benefit the Letter of Credit is to be
         issued, shall execute and deliver to Agent an appropriate application
         and agreement, being in the standard form of the Fronting Bank for such
         letters of credit, as amended to conform to the provisions of this
         Agreement if required by Agent. Agent shall give each Canadian Bank
         notice of each such request for a Canadian Letter of Credit.

                  In respect of each Canadian Letter of Credit and the drafts
         thereunder, if any, issued for the account of a Canadian Borrower,
         Canadian Borrowers agree (i) to pay to Agent, for the pro rata benefit
         of the Canadian Banks, (A) with respect to each Canadian Letter of
         Credit that is a standby letter of credit, a commission based upon the
         face amount of the Canadian Letter of Credit, which shall be paid
         quarterly in arrears, on the first day of each July, October, January
         and April, in an amount per annum equal to (1) the then current
         Applicable Margin for Canadian Fixed Rate Loans (i.e. the Applicable
         Margin for Canadian Fixed Rate Loans in effect on the date such
         Canadian Letter of Credit is issued and, as to each quarterly payment
         thereafter, the Applicable Margin for Canadian Fixed Rate Loans in
         effect on the date of such quarterly payment), times (2) the average
         undrawn face amount of such Canadian Letter of Credit during such
         fiscal quarter, and (B) with respect to each Canadian Letter of Credit
         that is a commercial documentary letter of credit, a non-refundable
         commission based upon the face amount of the Canadian Letter of Credit,
         which shall be paid on the date that any draw is made on a Canadian
         Letter of Credit, in an amount equal to (1) the then current Applicable
         Margin for Canadian Fixed Rate Loans, times (2) the amount drawn under
         the Canadian Letter of Credit; (ii) to pay to Agent, for the sole
         account of the Fronting Bank, an additional Canadian Letter of Credit
         fee, which shall be paid on each date that such Canadian Letter of
         Credit is issued or renewed at the rate of one-eighth percent (1/8 of
         1%) of the face amount of such Canadian Letter of Credit; and (iii) to
         pay to Agent for the sole account of the Fronting Bank, such other
         issuance, amendment, negotiation, draw, acceptance, telex, courier,
         postage and similar transactional fees as are generally charged by the
         Fronting Bank under its fee schedule as in effect from time to time.

                  Whenever a Canadian Letter of Credit is drawn, Canadian
         Borrowers shall immediately reimburse the Fronting Bank for the amount
         drawn. In the event that the amount drawn is not reimbursed by Canadian
         Borrowers within one (1) Business Day of the drawing of such Canadian
         Letter of Credit, at the sole option of Agent and the Fronting Bank,
         Canadian Borrowers shall be deemed to have requested a Canadian
         Revolving Loan, subject to the provisions of subsection 3(a) of Section
         2.1A in the amount drawn. Such Canadian Revolving Loan shall be
         evidenced by the Canadian Revolving Credit Notes. Each Canadian Bank
         agrees to make a Canadian Revolving Loan on the date of such notice,
         subject to no conditions precedent whatsoever. Each Canadian Bank
         acknowledges and agrees that its obligation to make a Canadian
         Revolving Loan pursuant to subsection 3(a) of Section 2.lA when
         required by this subsection 3(b) of Section 2.1A is absolute and
         unconditional and shall not be affected by any circumstance whatsoever,
         including, without limitation, the occurrence and continuance of an
         Unmatured Event of Default or Event of Default, and that its payment to
         Agent, for the account of the Fronting Bank, of the proceeds of such
         Canadian Revolving Loan shall be made without any offset, abatement,
         recoupment, counterclaim, withholding or reduction whatsoever and
         whether or not such Canadian Bank's Canadian Revolving Credit
         Commitment shall have been reduced or terminated. Canadian Borrowers
         irrevocably authorize and instruct Agent to apply the proceeds of any
         borrowing pursuant to this subsection 3(b) of Section 2.1A to
         reimburse, in full, the Fronting Bank for the amount drawn on such
         Canadian Letter of Credit. Each such Canadian Revolving Loan shall be
         deemed to be a Canadian Base Rate Loan unless otherwise requested by
         and available to Canadian Borrowers hereunder. Each Canadian Bank is
         hereby authorized to record on its records relating to its Canadian
         Revolving Credit Note such Canadian Bank's pro rata share of the
         amounts paid and not reimbursed on the Canadian Letters of Credit.

         6. The Credit Agreement is hereby amended to delete subparts (a), (b),
(c), (e) and (f) of Section 2.5 therefrom and to insert in place thereof,
respectively, the following:

                  SECTION 2.5. PAYMENT ON NOTES, ETC.

                  (a) PAYMENTS IN DOLLARS. All payments of principal, interest
         and commitment and other fees shall be made to Agent in Dollars and in
         immediately available funds for the account of the Banks. Payments must
         be received at the Designated Lending Office not later than 11:00 A.M.
         (Cleveland, Ohio time) to be deemed to have been made and received on
         that day.

                  (b)      [Intentionally omitted.]

                  (c)      [Intentionally omitted.]

                  (e)      PAYMENTS NET OF TAXES.

                           (i) GENERAL PROVISIONS. All payments under this
                  Agreement shall be made absolutely net of, without deduction
                  or offset for, and altogether free and clear of, any and all
                  present and future taxes, levies, deductions, charges and
                  withholdings and all liabilities with respect thereto, under
                  the laws of the United States of America or any foreign
                  jurisdiction (or any state or political subdivision thereof),
                  excluding income and franchise taxes imposed on any Bank (and
                  withholding relating thereto) under the laws of the United
                  States of America, the United Kingdom or Canada or any other
                  foreign jurisdiction (or any state or political subdivision
                  thereof). If any Borrower is compelled by law to deduct any
                  such taxes or levies (other than such excluded taxes) or to
                  make any such other deductions, charges or withholdings, then
                  such Borrower shall pay such additional amounts as may be
                  necessary in order that the net payments after such deduction,
                  and after giving effect to any United States or foreign
                  jurisdiction (or any state or political subdivision thereof)
                  income taxes required to be paid by the Banks in respect of
                  such additional amounts, shall equal the amount of interest
                  provided in Section 2.1 hereof for each Loan plus any
                  principal then due.

                           (ii) FOREIGN FACILITIES. In addition, and
                  specifically with respect to the Canadian Revolving Credit
                  Commitment and the UK Revolving Credit Commitment:

                                    (A) All payments on account of principal, if
                           any, and interest shall be made without set-off or
                           counterclaim and, unless otherwise required by law,
                           shall be made free and clear of and without deduction
                           for withholding tax or similar tax, present or
                           future, imposed by any taxing authority in Canada,
                           the United Kingdom or otherwise (in this subsection
                           (ii) hereof, a Tax). If a Borrower is required to
                           withhold or pay any Tax, it shall make the required
                           withholding and payment in accordance with and within
                           the time allowed by law, and shall nonetheless pay to
                           the appropriate Bank such additional amounts as are
                           necessary to cause such Bank actually to receive in
                           full all amounts (after taking account of any further
                           deduction or withholding which is required to be made
                           as a consequence of the payment of such additional
                           amounts) on account of principal and interest or
                           other fees or amounts owing to it hereunder, as if
                           such Tax had not been paid. As soon as practicable
                           after the date any Tax becomes due and payable, such
                           Borrower shall give to such Bank the original or a
                           copy of a receipt for the payment of the Tax, or if
                           such receipts are not issued by or received from the
                           taxing authority to which the Tax was paid, a
                           certificate of an officer of such Borrower,
                           confirming the date and amount of the payment so made
                           and reasonable details of the calculation of the
                           amount due.

                                    (B) Such Borrower shall indemnify and save
                           such Bank harmless from and against any claim,
                           liability, loss, cost, expense (including without

                                        8

                           limitation legal, accounting and other professional
                           fees, and interest and penalty charges or fines
                           imposed by any taxing authority in respect of or
                           arising from non-payment of such Tax) to which such
                           Bank may be exposed or which it may incur, by reason
                           of such Borrower's failure to make punctual payment
                           of any amount required to be paid to a taxing
                           authority pursuant to subsection (A) hereof.

                                    (C)     [Intentionally omitted.]

                                    (D)     [Intentionally omitted.]

                  (f) PAYMENTS TO BANKS. Upon Agent's receipt of payments
         hereunder, Agent shall immediately distribute, in immediately available
         funds, to each Bank its ratable share, if any, of the amount of
         principal, interest, and facility and other fees received by it for the
         account of such Bank. Each Bank shall record any principal, interest or
         other payment, the principal amounts of the Loans, all prepayments and
         the applicable dates, including Interest Periods, with respect to the
         Loans made and payments received by such Bank, by such method as such
         Bank may generally employ; provided, however, that failure to make any
         such entry shall in no way detract from the obligations of the
         respective Borrowers under each such Note. The aggregate unpaid amount
         of Loans, types of Loans and Interest Periods with respect to such
         Loans set forth on the records of Agent shall be rebuttably presumptive
         evidence of the principal and interest owing and unpaid on each Note.

         7. The Credit Agreement is hereby amended to delete Section 2.6(b)
therefrom in its entirety and to insert in place thereof the following:

         (b)      PREPAYMENT FEES.

                  (i) (A) If U.S. Borrower terminates the Revolving Credit
         Commitment on or prior to the date that is three (3) years from the
         Closing Date, then U.S. Borrower shall pay a prepayment fee to Agent,
         for the pro rata benefit of the Banks, in an amount equal to two
         percent (2%) times the Maximum Revolving Credit Commitment Amount, or
         (B) if U.S. Borrower terminates the Term Loan Commitment on or prior to
         the date that is three (3) years from the Closing Date, then U.S.
         Borrower shall pay a prepayment fee to Agent, for the pro rata benefit
         of the Banks, in an amount equal to two percent (2%) times the Maximum
         Term Loan Commitment Amount; provided, however, that so long as Agent
         remains Agent under any replacement credit facility, then the
         prepayment fees set forth in this Section 2.6(b)(i) shall not apply;

                  (ii) Without limiting anything else herein, in any case of
         prepayment of a Eurodollar Loan, U.S. Borrower agrees that if the
         reinvestment rate for Eurodollars, as quoted by the money desk of Agent
         (the "Reinvestment Rate"), shall be lower than the Eurodollar Rate
         applicable to the Eurodollar Loan that is intended to be prepaid
         (hereinafter,

                                        9

<PAGE>   10



         "Last Eurodollar"), then U.S. Borrower shall, upon written notice by
         Agent, promptly pay to Agent, for the benefit of the Banks, in
         immediately available funds, a prepayment fee equal to the product of
         (A) a rate (the "Prepayment Rate") which shall be equal to the
         difference between the Last Eurodollar and the Reinvestment Rate, times
         (B) the principal amount of the Eurodollar Loan that is to be prepaid,
         times (C) (i) the number of days remaining in the Interest Period of
         the Eurodollar Loan that is to be prepaid divided by (ii) three hundred
         sixty (360). In addition, U.S. Borrower shall immediately pay directly
         to Agent, for the account of the Banks, the amount of any additional
         costs or expenses (including, without limitation, reasonable or
         standard costs of telex, wires, or cables) incurred by Agent or the
         Banks in connection with the prepayment, upon U.S. Borrower's receipt
         of a written statement from Agent;

                  (iii) Without limiting anything else herein, in the case of
         prepayment of a Canadian Fixed Rate Loan, Canadian Borrowers agree that
         if the reinvestment rate for Eurodollars, as quoted by the money desk
         of Agent (the "Reinvestment Rate"), shall be lower than the Eurodollar
         Rate applicable to the Canadian Fixed Rate Loan that is intended to be
         prepaid (hereinafter, "Last Eurodollar"), then Canadian Borrowers
         shall, upon written notice by Agent, promptly pay to Agent at the
         appropriate Designated Lending Office, for the benefit of the Canadian
         Banks, in immediately available funds, a prepayment fee equal to the
         product of (A) a rate (the "Prepayment Rate") which shall be equal to
         the difference between the Last Eurodollar and the Reinvestment Rate,
         times (B) the principal amount of the Canadian Fixed Rate Loan that is
         to be prepaid, times (C) (1) the number of days remaining in the
         Interest Period of the Canadian Fixed Rate Loan which is to be prepaid
         divided by (2) three hundred sixty (360); and

                  (iv) Without limiting anything else herein, in any case of
         prepayment of a Eurodollar Loan, UK Borrowers agree that if the
         reinvestment rate for Eurodollars, as quoted by the money desk of Agent
         ("Reinvestment Rate"), shall be lower than the Eurodollar Rate
         applicable to the Eurodollar Loan that is intended to be prepaid
         (hereinafter, "Last Eurodollar"), then UK Borrowers shall, upon written
         notice by Agent, promptly pay to Agent, for the benefit of the Banks,
         in immediately available funds, a prepayment fee equal to the product
         of (A) a rate (the "Prepayment Rate") which shall be equal to the
         difference between the Last Eurodollar and the Reinvestment Rate, times
         (B) the principal amount of the Eurodollar Loan that is to be prepaid,
         times (C) (1) the number of days remaining in the Interest Period of
         the Eurodollar Loan that is to be prepaid divided by (2) three hundred
         sixty (360). In addition, UK Borrowers shall immediately pay directly
         to Agent, for the account of the Banks, the amount of any additional
         costs or expenses (including, without limitation, reasonable or
         standard costs of telex, wires, or cables) incurred by Agent or the
         Banks in connection with the prepayment, upon UK Borrowers' receipt of
         a written statement from Agent;

         8. The Credit Agreement is hereby amended to delete Section 2.7
therefrom in its entirety and to insert in place thereof the following:

                                       10

<PAGE>   11



                  SECTION 2.7. FACILITY AND OTHER FEES.

                  (a) U.S. Borrower shall pay to Agent, for the ratable account
         of the Banks, as a consideration for the Revolving Credit Commitments
         hereunder, a facility fee from the Closing Date until the last day of
         the Commitment Period equal to (i) the Facility Fee Rate times (ii) (A)
         the Maximum Revolving Credit Commitment Amount, less (B) the average
         aggregate principal amount of all Revolving Loans outstanding for the
         time period for which such payment is being made, less (C) the average
         aggregate amount of all issued and outstanding Letters of Credit for
         the time period for which such payment is being made. The facility fee
         shall be payable, in arrears, on July 1, 1999, and on the first day of
         each October, January, April and July thereafter and on the last day of
         the Commitment Period.

                  (b) U.S. Borrower shall pay to Agent, for the sole benefit of
         Agent, all fees set forth in the Agent Fee Letter.

         9. The Credit Agreement is hereby amended to delete subsection (c) of
Section 2.10 therefrom in its entirety and to insert in place thereof the
following:

                  (c) If the Canadian Exposure at any time exceeds the Canadian
         Revolving Credit Commitment, Canadian Borrowers shall, as promptly as
         practicable, but in no event later than the next Business Day, prepay
         an aggregate principal amount of Canadian Revolving Loans sufficient to
         bring the Canadian Exposure within the Canadian Revolving Credit
         Commitment.

         10. The Credit Agreement is hereby amended to delete Section 2.11
therefrom in its entirety and to insert in place thereof the following:

                  SECTION 2.11. CANADIAN REVOLVING CREDIT COMMITMENT. Borrowers
         acknowledge that, as of the Closing Date, no "Canadian Bank" exists
         hereunder to make Canadian Revolving Loans or issue Canadian Letters of
         Credit pursuant to the Canadian Revolving Credit Commitment. Despite
         the lack of a "Canadian Bank" hereunder, and with the understanding by
         Borrowers that one (1) or more of the Companies may incur adverse tax
         consequences as a result thereof, Borrowers desire that Canadian
         Borrowers utilize the Canadian Commitment and have requested of the
         Banks, and the Banks hereby agree, that, on an interim basis only,
         until such time as a "Canadian Bank" shall become a Canadian Bank
         hereunder, the Banks that are not Canadian Banks will make the Canadian
         Revolving Loans and Agent (or a Fronting Bank if Agent is not the
         Fronting Bank) will issue Canadian Letters of Credit hereunder. Such
         interim Canadian Revolving Loans shall for all purposes hereunder and
         under the other Loan Documents be Canadian Revolving Loans. More
         specifically, Borrowers agree with Agent and the Banks that the
         Canadian Revolving Loans made to Canadian Borrowers and Canadian
         Letters of Credit issued at the request of Canadian Borrowers by or on
         behalf of all of the Banks on an interim basis as described above shall
         be secured by all of the Collateral, as defined in the Security
         Documents

                                       11

<PAGE>   12



         executed by the Canadian Borrowers, regardless of the fact that those
         Security Documents refer to the extending of credit by "the Canadian
         Banks". The Canadian Borrowers shall execute a Canadian Revolving
         Credit Note payable to each Bank in the amount of each Bank's
         Commitment Percentage of the amount of the Canadian Revolving Credit
         Commitment. In addition, all indemnifications of the Canadian Banks by
         Canadian Borrowers shall be applicable to the Banks making the Canadian
         Revolving Loans and participating in the issuance of Canadian Letters
         of Credit to the extent of the Canadian Revolving Credit Commitment.
         Furthermore, at such time as a Canadian Bank becomes a Bank hereunder,
         (a) each Borrower agrees with Agent and the Banks that, in the event
         that such Canadian Bank requires an amendment to this Agreement in
         order to clarify and conform the interest rate and similar terms used
         in this Agreement with the normal procedures and term (including
         interest rate) typically used by such Canadian Bank, then each
         Borrower, Agent and the Banks shall promptly execute such amendment
         agreement, and (b) each Canadian Borrower agrees, upon request of
         Agent, to execute new Canadian Revolving Credit Notes in form and
         substance satisfactory to Agent and the Canadian Banks.

         11. The Credit Agreement is hereby amended to delete Section 3.2
therefrom in its entirety and to insert in place thereof the following:

                  SECTION 3.2. TAX LAW, ETC. In the event that by reason of any
         law, regulation or requirement or in the interpretation thereof by an
         official authority, or the imposition of any requirement of any central
         bank whether or not having the force of law, any Bank shall, with
         respect to this Agreement or any transaction under this Agreement, be
         subjected to any tax, levy, impost, charge, fee, duty, deduction or
         withholding of any kind whatsoever (other than any tax imposed upon the
         total net income of such Bank) and if any such measures or any other
         similar measure shall result in an increase in the cost to such Bank of
         making or maintaining any Fixed Rate Loan or in a reduction in the
         amount of principal, interest or facility fee receivable by such Bank
         in respect thereof, then such Bank shall promptly notify the
         appropriate Borrowers stating the reasons therefor. The applicable
         Borrowers shall thereafter pay to such Bank, upon demand from time to
         time on Interest Adjustment Dates with respect to such Fixed Rate Loan,
         as additional consideration hereunder, such additional amounts as shall
         fully compensate such Bank for such increased cost or reduced amount. A
         certificate as to any such increased cost or reduced amount, setting
         forth the calculations therefor, shall be submitted by such Bank to the
         appropriate Borrowers and shall, in the absence of manifest error, be
         conclusive and binding as to the amount thereof.

                  If any Bank determines that such Bank has actually received or
         realized any tax refund or any reduction of, or credit against, such
         Bank's tax liabilities in or with respect to the taxable year in which
         the additional amount is paid pursuant to this Section 3.2, such Bank
         shall pay to such Borrower an amount that such Bank shall, in its sole
         discretion, determine is equal to the net benefit, after tax, which was
         obtained by such Bank in such year as a consequence of such tax
         benefit; provided, however, that any Bank may determine in its

                                       12

<PAGE>   13



         sole discretion consistent with the policies of such Bank whether to
         seek a tax benefit, and nothing in this Section 3.2 shall require a
         Bank to disclose any confidential information to any Borrower
         (including, without limitation, its tax returns). If a Bank later
         determines, based on an audit or otherwise, that it was not entitled to
         the full amount of any refund reimbursed to any Borrower as aforesaid
         or that its net income taxes are not reduced by a credit or deduction
         for the full amount of taxes reimbursed to any Borrower as aforesaid,
         such Borrower, upon demand of such Bank, shall promptly pay to such
         Bank the amount so refunded to which such Bank was not so entitled, or
         the amount by which the net income taxes of such Bank were not so
         reduced, as the case may be.

                  Notwithstanding any other provision of this Agreement, after
         any such demand for compensation by any Bank, the appropriate
         Borrowers, upon at least three (3) Business Days' prior written notice
         to such Bank through Agent, may prepay any affected Fixed Rate Loan in
         full or convert such Fixed Rate Loan to a Base Rate Loan regardless of
         the Interest Period of any thereof. Any such prepayment or conversion
         shall be subject to the prepayment fees set forth in Section 2.6
         hereof.

         12. The Credit Agreement is hereby amended to delete Section 3.3
therefrom in its entirety and to insert in place thereof the following:

                  SECTION 3.3. FIXED RATE LOANS UNAVAILABLE OR INTEREST RATE
         UNASCERTAINABLE. In respect of any Fixed Rate Loan, in the event that
         Agent shall have determined that dollar deposits of the relevant amount
         for the relevant Interest Period for such Fixed Rate Loan are not
         available to Agent in the applicable eurodollar market, or that, by
         reason of circumstances affecting such market, adequate and reasonable
         means do not exist for ascertaining the interest rate applicable to
         such Interest Period, Agent shall promptly give notice of such
         determination to the affected Borrowers and (a) any notice of a new
         Fixed Rate Loan (or conversion of an existing Loan to a Fixed Rate
         Loan) previously given by such Borrowers and not yet borrowed (or
         converted, as the case may be) shall be deemed a notice to make a Base
         Rate Loan, and (b) the affected Borrowers shall be obligated either to
         prepay, or to convert to a Base Rate Loan, any outstanding Fixed Rate
         Loan on the last day of the then current Interest Period with respect
         thereto.

         13. The Credit Agreement is hereby amended to add new subparts (j), (k)
and (l) to Section 5.3 thereof as follows:

                  (j) as frequently as Agent may request, but no less frequently
         than monthly, a Borrowers' Certificate prepared by a Financial Officer
         of U.S. Borrower;

                  (k) within twenty (20) days after the end of each month, an
         accounts aging report and an inventory report of each Company, in form
         and substance satisfactory to Agent and the Required Banks; and


                                       13

<PAGE>   14



                  (l) a weekly delivery of Borrowers' assignment of sales.

         14. The Credit Agreement is hereby amended to delete subpart (c) of
Section 8.5 therefrom and to insert in place thereof the following:

                  (c) Except as set forth in Section 2.11 of this Agreement,
         only the Canadian Banks shall be obligated, upon the terms and
         conditions set forth in this Agreement, to fund Canadian Revolving
         Loans and participate in the issuance of Canadian Letters of Credit;
         provided that, anything in this Agreement to the contrary
         notwithstanding, upon the earlier of (i) the occurrence of an Event of
         Default specified in Section 7.12 hereof, or (ii) the acceleration of
         the Debt pursuant to Section 8.2 hereof (hereinafter, a "Equalization
         Event"), each Bank agrees with the other Banks that if it, at any time,
         shall obtain any Advantage over the other Banks, or any thereof, in
         respect of the Debt (except under Article III hereof) then outstanding,
         then such Bank having an Advantage shall purchase from the other Banks,
         including the Canadian Banks, for cash and at par, such additional
         participation in the Debt as shall be necessary to nullify the
         Advantage. As used herein, "Equalization Date" shall mean the date that
         the Equalization Event occurs.

         15. The Credit Agreement is hereby amended to delete Schedule 1 thereto
in its entirety and to insert in place thereof a new Schedule 1 in the form of
Schedule 1 attached hereto.

         16. The Credit Agreement is hereby amended to delete Exhibit C thereto
in its entirety and to substitute in place thereof a new Exhibit C in the form
of Exhibit C attached hereto.

         17. Concurrently with the execution of this First Amendment Agreement:

         (a) Canadian Borrowers shall execute and deliver to Agent for delivery
to the Banks new Canadian Revolving Credit Notes dated as of August 17, 1999,
and such Canadian Revolving Credit Notes shall be in the form and substance of
Exhibit C attached hereto; provided, however, that, upon each Bank's receipt of
a new Canadian Revolving Credit Note from Canadian Borrowers, such Bank shall
mark its Canadian Revolving Credit Note being replaced thereby "Replaced" and
return the same to Agent for delivery to Canadian Borrowers;

         (b) Borrowers shall cause each Guarantor of Payment to consent and
agree to and acknowledge the terms of this First Amendment Agreement;

         (c) Borrowers shall deliver such other documents as may reasonably be
required by Agent in connection with this First Amendment Agreement; and

         (d) Borrowers shall pay all legal fees and expenses of Agent in
connection with this First Amendment Agreement.


                                       14

<PAGE>   15



         18. Borrowers hereby represent and warrant to Agent and the Banks that
(a) each Borrower has the legal power and authority to execute and deliver this
First Amendment Agreement; (b) the officers executing this First Amendment
Agreement have been duly authorized to execute and deliver the same and bind
such Borrower with respect to the provisions hereof; (c) the execution and
delivery hereof by Borrowers and the performance and observance by Borrowers of
the provisions hereof do not violate or conflict with the organizational
agreements of any Borrower or any law applicable to any Borrower or result in a
breach of any provision of or constitute a default under any other agreement,
instrument or document binding upon or enforceable against any Borrower; (d) no
Unmatured Event of Default or Event of Default exists under the Credit
Agreement, nor will any occur immediately after the execution and delivery of
this First Amendment Agreement or by the performance or observance of any
provision hereof; (e) neither Borrower nor any Guarantor of Payment is aware of
any claim or offset against, or defense or counterclaim to, any of Borrowers' or
any Guarantor of Payment's obligations or liabilities under the Credit Agreement
or any Related Writing; and (f) this First Amendment Agreement constitutes a
valid and binding obligation of each Borrower in every respect, enforceable in
accordance with its terms.

         19. Each reference that is made in the Credit Agreement or any other
writing to the Credit Agreement shall hereafter be construed as a reference to
the Credit Agreement as amended hereby. Except as herein otherwise specifically
provided, all provisions of the Credit Agreement shall remain in full force and
effect and be unaffected hereby. This First Amendment Agreement is a Related
Writing as defined in the Credit Agreement.

         20. Each Borrower and each Guarantor of Payment, by signing below,
hereby waives and releases Agent and each of the Banks and their respective
directors, officers, employees, attorneys, affiliates and subsidiaries from any
and all such claims, offsets, defenses and counterclaims of which any Borrower
and any Guarantor of Payment is aware, such waiver and release being with full
knowledge and understanding of the circumstances and effect thereof and after
having consulted legal counsel with respect thereto.

         21. This First Amendment Agreement may be executed in any number of
counterparts, by different parties hereto in separate counterparts and by
facsimile signature, each of which when so executed and delivered shall be
deemed to be an original and all of which taken together shall constitute but
one and the same agreement.

         22. The rights and obligations of all parties hereto shall be governed
by the laws of the State of Ohio, without regard to principles of conflicts of
laws.

                         CANADIAN REVOLVING CREDIT NOTE

$________________                                                Cleveland, Ohio
                                                                August ___, 1999

         FOR VALUE RECEIVED, the undersigned, VENTURE LIGHTING POWER SYSTEMS,
NORTH AMERICA INC. (f.k.a. Ballastronix Incorporated) and CANADIAN LIGHTING
SYSTEMS HOLDING, INCORPORATED (collectively "Canadian Borrowers", and
individually "Canadian Borrower"), jointly and severally, promise to pay on the
last day of the Commitment Period, as defined in the Credit Agreement (as
hereinafter defined), to the order of _________ ("Canadian Bank") at the
Designated Lending Office, as defined in the Credit Agreement, the principal sum
of

 ......................................................................   DOLLARS

or the aggregate unpaid principal amount of all Canadian Revolving Loans made by
Canadian Bank to Canadian Borrowers pursuant to subsection 3 of Section 2.1A of
the Credit Agreement, whichever is less, in lawful money of the United States of
America. As used herein, "Credit Agreement" means the Credit Agreement dated as
of May 21, 1999, among Advanced Lighting Technologies, Inc., as U.S. Borrower,
Canadian Borrowers and certain Subsidiaries as UK Borrowers, the banks named
therein and PNC Bank, National Association, as Agent, as the same may from time
to time be restated, amended or otherwise modified. Capitalized terms used
herein shall have the meanings ascribed to them in the Credit Agreement.

         Canadian Borrowers also promise to pay interest on the unpaid principal
amount of each Canadian Revolving Loan from time to time outstanding, from the
date of such Canadian Revolving Loan until the payment in full thereof, at the
rates per annum which shall be determined in accordance with the provisions of
subsection 3 of Section 2.1A of the Credit Agreement. Such interest shall be
payable on each date provided for in such subsection 3 of Section 2.1A;
provided, however, that interest on any principal portion which is not paid when
due shall be payable on demand.

         The portions of the principal sum hereof from time to time representing
Canadian Base Rate Loans and Canadian Fixed Rate Loans, and payments of
principal thereof, shall be shown on the records of Canadian Bank by such method
as Canadian Bank may generally employ; provided, however, that failure to make
any such entry shall in no way detract from the obligations of Canadian
Borrowers under this Note.

         If this Note shall not be paid at maturity, whether such maturity
occurs by reason of lapse of time or by operation of any provision for
acceleration of maturity contained in the Credit Agreement, the principal hereof
and the unpaid interest thereon shall bear interest, until paid, at a rate per
annum

                                       18

<PAGE>   19



which shall be the Default Rate. All payments of principal of and interest on
this Note shall be made in immediately available funds.

         This Note is one of the Canadian Revolving Credit Notes referred to in
the Credit Agreement. Reference is made to the Credit Agreement for a
description of the right of the undersigned to anticipate payments hereof, the
right of the holder hereof to declare this Note due prior to its stated
maturity, and other terms and conditions upon which this Note is issued.

         Except as expressly provided in the Credit Agreement, each Canadian
Borrower expressly waives presentment, demand, protest and notice of any kind.

         This Note shall be governed by and construed in accordance with the
laws of the State of Ohio and the respective rights and obligations of Canadian
Borrower and Canadian Bank shall be governed by Ohio law, without regard to
principles of conflict of laws. Each Canadian Borrower hereby irrevocably
submits to the non-exclusive jurisdiction of any Ohio state or federal court
sitting in Cleveland, Ohio, over any action or proceeding arising out of or
relating to this Note, and each Canadian Borrower hereby irrevocably agrees that
all claims in respect of such action or proceeding may be heard and determined
in such Ohio state or federal court. Each Canadian Borrower, on behalf of itself
and its Subsidiaries, hereby irrevocably waives, to the fullest extent permitted
by law, any objection it may now or hereafter have to the laying of venue in any
action or proceeding in any such court as well as any right it may now or
hereafter have to remove such action or proceeding, once commenced, to another
court on the grounds of FORUM NON CONVENIENS or otherwise. Each Canadian
Borrower agrees that a final, nonappealable judgment in any such action or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on the judgement or in any other manner provided by law.

                  [Remainder of page intentionally left blank.]

                  5.1 ORGANIZATION; AUTHORITY. Each of the Company and each

consummate the transactions contemplated hereby and thereby. All necessary
corporate action has been (or will timely be) taken by and on behalf of the

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

the Indenture.

                  5.2 CAPITALIZATION. The authorized capital stock of the

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,

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

                  10.7 LAW GOVERNING. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York, without regard

herein, no modification, amendment or waiver of any provision of this Agreement
will be effective unless such modification, amendment or waiver is approved in
writing by the Company and Purchaser. The failure of any party to enforce any of

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

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

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).

        (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,


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

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

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


                                (B) A reclassification of the Common Shares
                (other than a change in par value, or from par value to no par
                value or from no par value to par value) into



                                    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
         Corporation with, or any sale, transfer or other disposition of all or
         substantially all the property, assets or business of the Corporation
         to, another corporation, person or entity, or

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

then, in any one or more of such cases, the Corporation shall give to each
holder of Series A Preferred Shares (A) at least 30 days prior written notice of
the date on which a record date shall be selected for such dividend,
distribution or right or for determining rights to vote in respect of any such
reorganization, reclassification, merger, consolidation, sale, transfer,
disposition, dissolution, liquidation or winding up, and (B) in the case of any
such reorganization, reclassification, merger, consolidation, sale, transfer,
disposition, dissolution, liquidation or winding up, at least 30 days prior
written notice of the date when the same shall take place. Such notice in
accordance with the foregoing clause also shall specify (A) the date on which
any such



                                    Page 15
<PAGE>   69

record is to be taken for the purpose of such dividend, distribution or right,
the date on which the holders of Common Shares shall be entitled to any such
dividend, distribution or right, and the amount and character thereof, and (B)
the date on which any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, dissolution, liquidation or winding
up is to take place and the time, if any such time is to be fixed, as of which
the holders of Common Shares shall be entitled to exchange their Common Shares
for securities or other property deliverable upon such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up. Each such written notice shall be
sufficiently given if addressed to each holder of Series A Preferred Shares at
the last address of such holder appearing on the books of the Corporation.

VI.      REDEMPTION OF SERIES A PREFERRED SHARES.

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

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

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

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




                                    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

<PAGE>   73

VIII.  NO REISSUANCE OF PREFERRED STOCK. No Series A Preferred Share or Series
A Preferred Shares acquired by the Corporation by reason of redemption,
purchase, conversion or otherwise shall be reissued, and all such shares shall
be cancelled, retired and eliminated from the shares which the Corporation
shall be authorized to issue. The President or any Vice President and the

and directed on behalf of the Corporation to file such documents from time to
time as may be necessary to reduce the authorized number of Series A Preferred
Shares accordingly.

the Company or any Company Beneficial Owner a bankrupt or insolvent or seeking

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

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"),
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
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>   113

                  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
of the Company, and in any event



                                      -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,
approval, declaration, delivery or other communication hereunder to be made

                  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

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

provision or the remaining provisions of this Warrant.

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"),
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.

                  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>   134

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

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.

under Section 9 of this Warrant. The Company agrees that monetary damages would

adequate.

Warrant shall be interpreted in such manner as to be effective and valid under

         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

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

               d.   Except as provided in clause e. below and subject to
compliance with the terms of the Ohio Control Share Acquisition Act, if
applicable, upon the third occurrence of the EBITDA Ratio being less than the
Required Ratio for any Determination Period (a "Third Occurrence Failure"):

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

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

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

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

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


                                       8
<PAGE>   9

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

         2.3   PURCHASER'S RIGHTS IN THE EVENT OF GOVERNMENTAL PROCEEDING. If
any action or proceeding (a "Proceeding") before any Governmental Body or agency
is pending or threatened against the Company or any beneficial owner of 5% or
more of any class of equity securities of the Company (a "Company Beneficial
Owner"), including, without limitation, any Proceeding (i) seeking to 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.

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

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

exercise of the Ruud Option, of written notice thereof at the notice address for
Hellman and Ruud, respectively, set forth in Section 4.4 hereof (an "Option
Notice"). The Hellman Option and the Ruud Option must both be exercised if

Option Closing is conditioned upon the receipt by the Company and the
Shareholders of all governmental and regulatory approvals required for the
ownership of the Hellman Option Shares or the Ruud Option Shares, as the case
may be. At an Option Closing, certificates representing the Hellman Option
Shares or the Ruud Option Shares, as the case may be, shall be delivered,
together with stock powers duly executed in blank, to the Purchaser free and
clear of any and all claims, liens, charges, pledges or encumbrances and the
Purchaser shall deliver to Hellman and Ruud, as the case may be, their
respective allocable portion of the Option Purchase Price. Hellman and Ruud
shall pay any and all transfer and similar taxes imposed in connection with the
sale of the Hellman Option Shares and the Ruud Option Shares to Purchaser.

                  "Transfer" shall mean any disposition of any Warrant or
Warrant Share or of any interest in either thereof that would constitute a sale
thereof within the meaning of the Securities Act.

                  "Transfer Notice" shall have the meaning set forth in Section
9.2.

                  "Warrants" shall mean this Warrant and all warrants issued
upon transfer, division or combination of, or in substitution for, this Warrant.
All Warrants shall at all times be identical as to terms and conditions and
date, except as to the number of Common Shares for which they may be exercised.

                  "Warrant Price" shall mean an amount equal to (i) the number
of Common Shares being purchased upon exercise of this Warrant pursuant to
Section 2.1, multiplied by (ii) the Current Warrant Price as of the date of such
exercise.

                  "Warrant Shares" shall have the meaning set forth in the
introductory paragraph on the first page hereof.

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"),
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>   34

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>   35

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>   36

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>   37

                  (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>   38

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>   39

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>   40

                  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>   41

         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

                  15.1. NONWAIVER AND EXPENSES. No course of dealing or any

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

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

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

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

                  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"),
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>   56

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>   57

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>   58

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>   59

                  (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>   60

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>   61

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>   62

                  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

                  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

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

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

10.      SUPPLYING INFORMATION

Warrant or Restricted Common Shares.

11.      LOSS OR MUTILATION

reasonably satisfactory to it of the ownership of and the loss, theft,

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

Holder as soon as practicable after the end of each fiscal year of the Company,

    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.

However, it should be noted that our audit was not directed primarily toward
obtaining knowledge of such noncompliance.

This report is intended solely for the information and use by the Company and

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>   9



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>   10


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>   11


                  (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>   12


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>   13


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>   14



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>   15

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>   16

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>   18

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>   19

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>   20

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

setting forth in each case in comparative form the figures for the corresponding

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

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.

                  15.3. 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-

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.

                        LAMP MATERIALS PURCHASE AGREEMENT


         THIS AGREEMENT is entered into as of the 30th day of September 1999, by
and between GENERAL ELECTRIC COMPANY, a New York corporation, acting through its
GE LIGHTING business, having offices at Nela Park, Cleveland, Ohio 44112
("Purchaser"), APL ENGINEERED MATERIALS, INC., an Ohio corporation having
offices at 2401 N. Willow Road, Urbana, Illinois 61801 ("Seller"), and ADVANCED
LIGHTING TECHNOLOGIES, INC., an Ohio corporation having offices at 32000 Aurora
Road, Solon, Ohio 44139 ("ADLT").


                                   WITNESSETH:

         WHEREAS, Purchaser purchased certain metal halide pellets,
sodium-mercury amalgams and other materials from Seller pursuant to the Metal
Halide Purchase Agreement (the "MH Purchase Agreement") dated January 1, 1989
and the Amalgam Purchase Agreement dated April 24, 1987 (the "Amalgam
Agreement"); and

         WHEREAS, although the MH Agreement and the Amalgam Agreement expired on
November 30, 1998 and December 31, 1998, respectively, Purchaser has continued
purchasing Product (defined below) from Seller; and

         WHEREAS, Purchaser and Seller have agreed to replace the MH Purchase
Agreement and the Amalgam Agreement with this Lamp Materials Purchase Agreement
(which is and shall be deemed to be an agreement supplementary to the License
Agreement defined below, as contemplated by section 365 of Title XI of the U.S.
Code), and to enter into a Know How and Patent License and Technical Assistance
Agreement (the "License Agreement") pursuant to which, among other things,
Purchaser has a non exclusive right to use the Know How Record (defined below)
under the conditions specified therein.

         NOW THEREFORE, in consideration of the foregoing, and the mutual
promises hereinafter contained, the parties hereto agree as follows:


         1. DEFINITIONS. For purposes of this Agreement:

         "Change of Control" shall mean with respect to an entity, any of the
following: (a) any person or group of persons shall have acquired beneficial
ownership (as defined in Rule 13d-3, promulgated under the Securities Exchange
Act of 1934, as amended) of 50% or more of the issued and outstanding shares of
common stock of the entity, (b) the entity shall be a party





                                      -1-
<PAGE>   2

to a merger or consolidation in which it is not the survivor or in which the
entity's shareholders immediately prior thereto own less than a majority of the
outstanding voting stock of the survivor, or (c) the entity shall have sold,
leased or otherwise transferred all or substantially all of its assets in one
transaction or a series of related transactions.

         "Consignment Agreement" shall mean the Consignment Agreement between
Purchaser and Seller, substantially in the form of EXHIBIT "D" hereto, which is
and shall be deemed to be an agreement supplementary to the License Agreement,
as contemplated by section 365 of Title XI of the U.S. Code.

         "Know How Record" shall have the meaning ascribed to it in the License
Agreement, as such record has been and continues to be updated from time to
time, and shall include a written description that clearly defines the
processes, procedures, quality systems, equipment and apparatus used from time
to time in the production of metal halide pellets and sodium mercury amalgams.
The Know How Record will at all times enable technicians to produce Products to
the desired specifications.

         "Products" shall mean metal halide pellets and sodium amalgams covered
by the Specifications (defined below) that are used as part of the fill in high
intensity discharge lamps for general lighting purposes manufactured by
Purchaser, and such other materials and products that are listed on EXHIBIT "A",
as such exhibit may be updated from time to time by mutual agreement of the
parties.

         "QPS" shall mean the Quality Procurement Specification of Purchaser
which includes both the Product specifications currently being required by
Purchaser (the "Specifications") and the procedural requirements which are
currently being utilized by Purchaser and Seller for Products, as each of the
same may be modified from time to time by mutual agreement of the parties.


         2. SCOPE. All purchases of Products by Purchaser shall be subject to
the terms and conditions of this Agreement and the Consignment Agreement. In the
event of any inconsistency between any provisions of Purchaser's purchase orders
or releases (except provisions specifying the types and quantities ordered,
delivery dates and the method of shipment), or any provisions of any Seller's
quotation, proposal, acknowledgement, acceptance, invoice, or any other writing
issued in connection herewith and this Agreement and the Consignment Agreement,
this Agreement and the Consignment Agreement shall prevail.


                                      -2-
<PAGE>   3


         3. SALE AND PURCHASE OBLIGATIONS. During the term of this Agreement:

         (a) Seller agrees to sell to Purchaser one hundred percent (100%) of
Purchaser's requirements for Products and Purchaser agrees that at least fifty
percent (50%) of Purchaser's total requirements for metal halide pellets and
sodium amalgams (by volume) in each year will be purchased from Seller
(Purchaser's "Annual Purchase Obligation").

         (1) Within thirty (30) days of a request from Seller received by
         Purchaser on or before January 31 of a year, Purchaser shall deliver
         Seller a statement from its Sourcing Manager confirming that Purchaser
         fulfilled its Annual Purchase Obligation for the prior year.

         (2) In the event that Purchaser does not fulfill its Annual Purchase
         Obligation for any year (a "Deficiency"), Purchaser may cure such
         failure in the next succeeding year by purchasing an aggregate amount
         of Product (by volume) equal to the Deficiency, in addition to its
         Annual Purchase Obligation for such succeeding year.

         (b) Seller agrees that from the ninetieth (90th) day following the date
of this Agreement and thereafter Seller shall at all times maintain at a
location that is protected from fire, theft and other comparable risks in a
manner that is reasonably acceptable to Purchaser, an inventory of quality
approved Products specifically for supplying Purchaser (the "Product
Inventory"). The amount of the Product Inventory shall at all times be no less
than the amount that Purchaser has ordered in the immediately preceding sixty
(60) day period. Seller shall provide written certification semi-annually to
Purchaser that such stock is in place and fairly represents a reasonable mix of
the different product types based on the Purchaser's consumption during the
immediately preceding sixty (60) day period.

         (c) Seller agrees to maintain and hereby acknowledges its relationship
with a secondary producer of Products (i.e., Aldrich-APL, L.L.C.), which
secondary producer is capable of fulfilling the requirements of this Agreement
if for any reason Seller is unable to do so.


         4. SPECIFICATIONS; QPS. (a) All Products supplied by Seller shall be in
the form of and must strictly conform to the Specifications and the QPS.

         (b) In order to monitor the implementation and ongoing execution of six
sigma processes in the manufacture of Products, Seller agrees to conduct a
minimum of one technology review per year at Seller's factory premises which
will serve to update Purchaser on the processes, quality systems, equipment and
apparatus used in manufacturing Products. This review will include close




                                      -3-
<PAGE>   4

inspection of the production process in operation and will be deemed to be
Proprietary Information as defined in section 8(a) of this Agreement. The timing
of such reviews will be mutually agreed upon by each party at least 30 days in
advance.

         5. PRICES. (a) The price, excluding all state, federal and local taxes,
for all Products during the term of this Agreement shall be as detailed in
EXHIBIT "B". Prices are FOB Seller's dock, with the terms of payment referred to
in paragraph 4 of the Consignment Agreement being 1.5%, 15 net 60 days.

         (b) If Purchaser requests Product having less than 100 grams per vial,
the prices set forth in EXHIBIT "B" for that Product will be increased to
include an ampouling charge at the rates set forth in EXHIBIT "C" attached
hereto.

         6. TERM. This Agreement shall become effective on the date of the last
signature hereto and shall, unless terminated earlier pursuant to the terms of
this Agreement, have a term of five (5) years. Thereafter, it shall
automatically renew for consecutive five (5) year terms unless any one of the
following occurs: (1) this Agreement is replaced by another Agreement; or (2)
this Agreement is terminated by written notice delivered by either Seller or
Purchaser at least one hundred and eighty (180) days before the expiration of
the five (5) year period. Upon a renewal of this Agreement pursuant to this
Section 6, the pricing of the Products shall remain at the prices set forth in
EXHIBIT "B".

         7. TERMINATION.

         (a) Purchaser may terminate this Agreement if Seller fails to deliver
to Purchaser, within sixty (60) days of the date specified in any purchase order
of Purchaser, qualified, existing Products complying with the QPS and
Specifications applicable to such order; PROVIDED, HOWEVER, if failure of
delivery is caused by an extraordinary event beyond the reasonable control of
Seller and without the gross negligence of Seller, then the sixty (60) day
period shall be extended to one hundred twenty (120) days.

         (b) Either party may terminate this Agreement upon prior written notice
to the other party in the event of the occurrence of a material breach by the
other party of any of the terms and conditions of this Agreement, which breach
has continued unremedied for forty five (45) days after receipt of notice
thereof (which notice shall specify the material breach).

is understood to mean technical information and data made available by one party
to the other in written, machine recognizable, graphic or sample form including,
without limitation, drawings, photographs, sketches, models, mockups, and design
or performance specifications, provided such information is clearly and
conspicuously labeled with "Proprietary Information" or other equivalent legend.
Proprietary Information is also understood to include such information and data
disclosed orally or visually, provided that it is identified at the time of
disclosure as proprietary and, provided further, that within thirty (30) days
thereafter, a written summary of such oral or visual disclosure bearing the
aforesaid type of label or legend, is provided to the receiving party.

         (b) Proprietary Information furnished hereunder shall be:

             (1) used by the receiving party solely for the purpose of this
             Agreement; and

             (2) held in confidence for the term of this Agreement and ten (10)
             years after its termination.

Except as provided in the License Agreement, such Information shall not, without
prior written consent of the disclosing party, be used in connection with the
manufacture or purchase of metal halide pellets or sodium amalgam products for
or from any third party or for any other purpose unrelated to this Agreement.
Moreover, within the receiving party, dissemination of Proprietary Information
of GE or Proprietary Information of Seller will be restricted to those employees
involved in performance of this Agreement and who have been informed of the
terms and conditions hereof.

         (c) Notwithstanding the above stated obligations of restricted use and
confidentiality, the receiving party will not be liable for disclosure or use of
such party of the information which it can establish by tangible evidence:

             receipt from the disclosing party;

             (2) is or becomes known to the public through disclosure in a
             printed publication or in an issued patent (without breach of the
             receiving party's obligations hereunder);

             (3) was rightfully acquired by the receiving party from a third
             party, which generated such information independently of
             Proprietary Information;


                                      -5-
<PAGE>   6

             (4) was necessarily disclosed by its use or embodiment in a
             product that has been placed in commerce by the disclosing party;
             or

             (5) was independently developed by the receiving party provided
             that the person or persons developing the same have not had
             access to Proprietary Information.

         (d) All Proprietary Information shall remain the property of the
disclosing party. Upon demand, all Proprietary Information and any copies shall
be immediately returned, including any written notes which may have been made
regarding same, to the disclosing party.

         (e) No rights or obligations other than those expressly recited herein
are to be implied. No license is hereby granted or implied, by estoppel or
otherwise, under any patents (existing or future) or for any use of Proprietary
Information except such use as is expressly contemplated by this Agreement and
the License Agreement.

         9. WARRANTY. Seller warrants that any Products sold hereunder will be
free from defects in title, workmanship, and materials and will conform to the
Specifications. This warranty does not apply to defects caused by abuse, misuse,
neglect, improper application, or alteration. Seller will require the return of
Products claimed to be defective for examination. Provided that the Products are
stored as provided in the QPS and Specifications, this warranty shall apply to
Products, which are first claimed to be defective within one year after their
date of delivery to Purchaser.

SELLER MAKES NO OTHER WARRANTIES OTHER THAN THOSE SET FORTH HEREIN (INCLUDING,
WITHOUT LIMITATION, THE QPS AND SPECIFICATIONS) AND THESE WARRANTIES ARE IN LIEU
OF ALL OTHER WARRANTIES WHETHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED
TO, ANY WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

         Seller's obligation under this warranty is expressly limited to
replacement of Products involved, or if Seller is unable to replace such
Products, to refund the then current market sales price for the Products
involved. The alternative remedies granted herein shall be Purchaser's, and
anyone claiming under or through Purchaser, exclusive remedies. Seller will not
be liable in any case for any loss of use, revenue, or profit, or any
consequential damages arising out of, in connection with, or resulting from, the
Products or any defects therein, even if Seller has been advised of the
possibility of such potential damages.

         10. INSPECTION. All Products shall be subject to inspection and test as
provided for in the QPS and Specifications. If any of the Products are not in
conformity with the Specifications, Purchaser in addition to any other rights it
may have, may (a) reject the Products and return them, (b) re-inspect the
Products at Seller's expense or (c) waive the defects and equitably reduce the
price. If Purchaser does not inspect the Products or give notice of their
rejection within sixty (60) days after their receipt, such Products shall be
considered accepted. Purchaser's failure to inspect or reject any products shall
not relieve Seller from its obligations under this Agreement.

         11. COMPLIANCE WITH THE LAWS. Seller agrees to comply with the
applicable provisions of any federal, state or local law or ordinance and all
lawful orders, rules, and regulations issued thereunder and any provisions,
representations or agreements, or contractual clauses required thereby to be
included or incorporated by reference or operation of law in the contract which
results from acceptance of any order and dealing with the Equal Opportunity
(Executive Order 11245 as amended by Executive Orders 11375 and 12086),
Employment of Veterans (Executive Order 11701), Employment of Handicapped
(Executive Order 11758 as amended by Executive Order 11867), Employment
Discrimination Because of Age (Executive Order 11141), Utilizations of
Disadvantaged Business Enterprises (Executive Order 11625 and Public Law
95.507). Seller certifies that with respect to orders which exceed $10,000 it is
in compliance with the requirement for non-segregated facilities set forth in 41
0CFR Chapter 60-18.


         12. CHANGE OF CONTROL: TRANSFER OF SELLER. In the event there is a
Change of Control of Seller or ADLT proposes to sell, transfer or otherwise
dispose (a "Transfer") of Seller to any third party (whether as an asset or
stock transfer, or singly or as a part of a larger transaction, or otherwise),
Purchaser will have the sole right to continue or terminate this Agreement.
Purchaser may exercise this right to terminate in whole only and not in part, by
written notice to Seller and ADLT within sixty (60) days after being notified of
the circumstances of the Change of Control or Transfer of Seller and the terms
and conditions thereof. Purchaser's failure to provide notice of termination
within such sixty (60) days shall be deemed to be Purchaser's election to
continue this Agreement in accordance with its terms.

         13. RIGHT OF FIRST REFUSAL. (a) In the event that ADLT receives and
proposes to accept a bona fide offer (an "Offer") from any third party lighting
products competitor of Purchaser (an "Offeror") for the purchase of all or
substantially all of Seller (whether as an asset, stock transfer, or otherwise)
then, in addition to the rights specified in Section 12:


                                      -7-
<PAGE>   8

          (1) ADLT will deliver a written notice of the Offer to Purchaser
          specifying the identity of the Offeror, the proposed price and other
          relevant terms and conditions of the Offer, a copy of which will be
          included with the notice.

          (2) Purchaser will have the right, for a period of ninety (90) days
          following receipt of the notice referred to above (subject to any
          extension necessary to comply with any applicable regulatory
          requirement), to purchase Seller from ADLT at the price and on the
          other relevant terms and conditions contained in the Offer. Such right
          may be exercised by Purchaser by delivering written notice during such
          ninety (90) day period to ADLT of its election to make such a
          purchase. Notwithstanding the foregoing, if the Offer is not for cash,
          Purchaser will have the right to make such purchase for equivalent
          cash consideration as determined by an investment banking firm of
          national reputation chosen by mutual agreement of Purchaser and ADLT,
          which right Purchaser may exercise by delivering a written notice
          during the thirty (30) day period following receipt of such investment
          banking firm's determination.

          (3) ADLT shall, within thirty (30) days after receipt from Purchaser
          of its election to purchase, sell Seller to Purchaser at the price and
          on the terms and conditions set forth in subsection (2) above.

          (b) If Purchaser does not exercise its right to purchase pursuant to
subsection (a) above, ADLT may sell such business to the Offeror, but only on
the terms and conditions and at the price set forth in the Offer, PROVIDED,
HOWEVER, that any such transaction shall be subject to the continuing rights of
Seller pursuant to Section 12. If a sale or other transfer to the Offeror is not
completed within 120 days following the end of the ninety (90) day period
referred to in subsection (a)(2) above, ADLT may not sell or otherwise transfer
Seller without again complying with the provisions of this Section 13.

          (c) Purchaser's rights under this Section 13 shall terminate upon
termination of this Agreement for any reason.


          14. GENERAL.

         (a) The failure of each party to enforce at any time, or for any period
of time, any of the provisions of this Agreement shall not be construed as a
waiver of such provision or of the right of the party thereafter to enforce each
and every such provision. Any waiver must be in writing, signed by the party to
be bound thereby. Any waiver of any term or condition of this Agreement shall
not be construed to be a waiver of any other term or condition or a waiver of
the same term and condition subsequently to be kept and performed.


                                      -8-
<PAGE>   9

         (b) Neither this Agreement nor any rights or obligations hereunder may
be assigned, subcontracted or otherwise transferred by either party without the
prior written consent of other; PROVIDED, HOWEVER, that Purchaser may assign its
rights and obligations to an entity acquiring the metal halide lamp
manufacturing business of Purchaser, without prior written consent of Seller, if
the proposed assignee accepts in writing the provisions of this Agreement and
becomes, in all respects, bound thereby in the place and stead of Purchaser.

         (c) Except with regard to the provisions of the Consignment Agreement
and the License Agreement, this Agreement embodies the entire agreement of the
parties with respect to the subject matter hereof and supersedes and cancels any
and all prior understandings and/or agreements.

         (d) This Agreement may not be modified except in writing signed by an
authorized representative of each party hereto.

         (e) The headings of the various Articles of this Agreement are inserted
only for the convenience of the parties in locating a particular provision and
shall not limit or be utilized in construing the meaning of any Article.

         (f) The law of the State of Ohio shall govern the interpretation and
application of this Agreement without regard to its conflicts of law provisions.

         (g) All notice under this Agreement shall be in writing and directed to

                                    AGREEMENT
                                    ---------

fourth day of JANUARY, 1999, between, APL Engineered Materials, Inc.
(hereinafter "Consignor'), located at 2401 N. Willow Road, Urbana, IL
61802-7332, and GE Lighting, (hereinafter "Consignee"), located at Nela Park,
1975 Noble Road, Mail Stop 327 D, Cleveland, Ohio 44112-6300.

In consideration of the mutual promises made herein, it is agreed as follows:

1. CONSIGNMENT STOCK. Consignor will maintain a consignment stock of "Halide
Pellets" (hereinafter Consignment Stock") in the warehouse of Consignee located
at GE Lighting, Ravenna Lamp Plant, 6800 North Chestnut Street, Ravenna, Ohio
44266. Consignee may place orders upon Consignor for consignment stock either
verbally or in writing, however, if the order is placed verbally, a written
confirmation or purchase order of said order shall be provided to Consignor.
Consignee shall receive such consignment stock and furnish Consignor with a copy
of the signed packing slip for each shipment of consignment stock. The shipping
papers shall note that such shipments are for the "consignment stock". As owner
and holder of title to said consignment stock, Consignor may at any time, and at
Consignor's sole discretion, request return of any consignment stock.

2. Title. Title to the consignment stock shall be vested in Consignor until said
stock is withdrawn by any party other than Consignor from the consignment
storage area as described herein. A withdrawal shall be considered to have taken
place when any package of consignment stock is opened, at which time the entire
contents of the opened package should be physically removed from the consignment
storage area reserved for Consignor. When making withdrawals from consignment,
Consignee will endeavor to apply the first-in-first-out rule by withdrawing
consignment stock in the order that it was received from Consignor. Consignee
agrees that it will not perform any acts or make any representations which could
cause Consignee's creditors, potential creditors, customers or the general
public to believe that the stock in the consignment storage area is owned by
Consignee.

3. STORAGE. Consignee will receive the consignment stock from Consignor and,
without expense to Consignor, will (a) hold and care for the consignment stock
as the property of Consignor; (b) keep the consignment stock in a location which
is physically separate and distinct from the Consignees property or the property
of Consignee's suppliers or other consignors (referred to in this Agreement as
the "consignment storage area"), at all times maintaining identification
markings on the consignment stock indicating that said stock is the property of
Consignor; (c) post a large sign evidencing the consignment arrangement and
stating that Consignor is the owner of the property, and containing the
following information:

          "This property is on consignment."
          Any matter relating thereto should be directed to: Karen Edmondson

(d) keep the consignment stock in a safe, secured and protected storage area;
and (e) maintain the consignment stock in good condition and in such manner as
to be accessible for ready inspection and identification thereof by Consignor,
its employees or agents.

4. PAYMENT FOR STOCK WITHDRAWN FROM CONSIGNMENT. Consignee shall notify
Consignor on a monthly basis of consignment stock that has been withdrawn from
the consignment storage area. Consignor will invoice Consignee for any
consignment stock which has been withdrawn and Consignee shall be required to
pay the invoiced amount for such consignment stock under the terms of sale then
existing between Consignor and Consignee. Consignee shall be required to keep
records of the location of any consignment stock which has been withdrawn from
the consignment storage area and not paid for by Consignee, and shall make said
records available upon request by Consignor, its employees or agents.

Consignee for any consignment stock which is not present in the consignment
storage area when the inventory is taken, and has not already been paid for by

the terms of sale then existing between Consignor and Consignee.

6. BOOKS/RECORDS. Consignee will keep correct books of account of all
consignment stock, including records of all receipts and withdrawals therefrom.

levied by any governmental agency and Consignor will pay all such taxes directly
to the appropriate taxing agency. If Consignee includes consignment stock owned
by Consignor in Consignee's inventory for personal property tax purposes,
Consignee shall not seek reimbursement from Consignor for such payments, nor
shall Consignee offset any such payments made against any amounts due Consignor
for consignment stock.

8. LOSS/DAMAGE. Consignee shall be required to obtain and keep in force, at its
expense, insurance to cover damage to the consignment stock from theft, fire or
acts of God, with Consignor being the named beneficiary of said insurance. At

date of termination of this Agreement, and all such invoices and any outstanding
invoices for consignment stock shall become immediately due and payable.

         4.       PROPRIETARY INFORMATION.

         (a) For purposes of this Agreement, the term "Proprietary Information"
is understood to mean the Know How Record and Product Technology which is
clearly and conspicuously labeled with "Proprietary Information" or other
equivalent legend. Proprietary Information is also understood to include such
information and data disclosed orally or visually provided it is identified at
the time of disclosure as proprietary and, provided further, that within thirty

bearing the aforesaid type of label or legend, is provided to the receiving
party.

         (b) Proprietary Information furnished hereunder shall be (1) used
solely for the purpose of the license granted pursuant to section 2 and as
contemplated by this Agreement; and (2) held in confidence for the term of this
Agreement and ten (10) years after its termination.

         (c) GEL agrees that Proprietary Information will be restricted to those
employees involved in performance of this Agreement and the Materials Purchase
Agreement who have been informed of the terms and conditions hereof.

         (d) Notwithstanding the above stated obligations of restricted use and

such party of the information which it can establish by tangible evidence:

             (1) was rightfully in its possession or known to it prior to
             receipt from the disclosing party;

             (2) is or becomes known to the public through disclosure in a
             printed publication or in an issued patent (without breach of the
             receiving party's obligations hereunder);

             (3) was rightfully acquired by the receiving party from a third
             party, which generated such information independently of
             Proprietary Information;


                                      -5-
<PAGE>   6

             (4) was necessarily disclosed by its use or embodiment in a product
             that has been placed in commerce by the disclosing party; or

             (5) was independently developed by the receiving party provided
             that the person or persons developing the same have not had access
             to Proprietary Information.


         5. BANKRUPTCY. In the event either ADLT or APL commences or has
commenced against it a bankruptcy case or similar proceeding (such party, the
"Bankrupt Party"), GEL (the "Non-Bankrupt Party")shall have all rights available
to licensees under the Bankruptcy Code (defined below). Unless and until such
time as the Bankrupt Party or its trustee may reject any license granted
hereunder, a Non-Bankrupt Party may request in writing that the Bankrupt Party
or its trustee, as the case may be, (a) perform under the terms and conditions
of this License and other agreements deemed supplementary hereto, (b) not
interfere with the rights of the Non-Bankrupt Party as provided in this License
to the Know How Record and Product Technology and (c) require the provision of
the Know How Record and the Product Technology. The Bankrupt Party acknowledges
and agrees that if it as a debtor-in-possession or its trustee in Bankruptcy in
a case under Title 11 of the United States Code, as amended (the "Bankruptcy
Code"), rejects any of the rights granted in this License, as provided in
Section 365(n) of the Bankruptcy Code, the Non-Bankrupt Party may elect to
retain its rights to the Know How Record and Product Technology under this
License. Upon written request of the Non-Bankrupt Party to the Bankrupt Party or
its trustee, the Bankrupt Party or its trustee shall not interfere with the
rights of the Non-Bankrupt Party to continue its use of the Know How Record and
Product Technology, including any right to obtain the same from another entity.
The parties agree that the Bankrupt Party will seek an order assuming this
License Agreement within 60 days of the commencement of a bankruptcy case or
other similar proceeding. This Section 5 shall survive any termination of this
License.

         6. TERM. This Agreement shall become effective as of the date first
above written upon the execution hereof by all parties and shall continue for
the longer of (a) ten (10) years after or (b) the life of the last Patent issued
or applied for prior to, the date on which GEL ceases to purchase any Products
from APL (or any successor of APL) under the Materials Purchase Agreement or
otherwise, unless the parties hereto otherwise agree in writing.

         ADLT to meet their respective obligations to GEL under or arising out
         of this Agreement.

             (c) There are no pending or threatened claims alleging, or
         potential claims that could reasonably be expected to be alleged, that
         any or all of the Know How Record or Product Technology infringes or
         conflicts with the intellectual property rights of others.


         8. INDEMNITY.

         (a) Each of APL and ADLT, jointly and severally, agrees to defend,

of any or all of its representations or warranties; and (ii) any allegation that
use of any or all of the Know How Record or Product Technology infringes,
interferes with, or otherwise violates the intellectual property rights or other
proprietary rights of a third party.

         (b) In the event that the Know How Record or Product Technology
licensed to GEL pursuant to this Agreement, in whole or in part, is finally
determined, by settlement or judicial action, to infringe a third party
intellectual property right or other proprietary right, then at the written
request and option of GEL, APL shall (i) modify, at APL's sole cost and expense,
the allegedly infringing Know How Record or Product Technology to be
non-infringing; or (ii) substitute, at APL's sole cost and expense,
non-infringing intellectual property.

For purposes of calculating the unaudited ratio of earnings to fixed charges,
earnings consist of income (loss) before provision for income taxes plus fixed
charges. Fixed charges consist of interest charges and amortization of debt
issuance costs, whether expensed or capitalized, and that portion of rental
expense that is representative of interest. In the three months ended September
30, 1999, earnings were inadequate to cover fixed charge requirements by $580.
In the three months ended September 30, 1998, earnings were inadequate to cover
fixed charge requirements by $1,054.
