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

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

share (determined by the ratio of Purchaser's then existing holdings of Common
Shares and Common Share equivalents (including, without limitation, Conversion

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
Holder, as soon as practicable after the end of each of the first three quarters
of the Company, and in any event



                                      -13-
<PAGE>   42

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.


                                      -14-

15.      MISCELLANEOUS

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

                  15.2. NOTICE GENERALLY. Any notice, demand, request, consent,

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

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

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

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

                  15.7. HEADINGS. The headings used in this Warrant are for the

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

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
                    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>   63

         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>   64

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.


                                      -14-

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

    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.
