          (a) Any sale, transfer, assignment or hypothecation of this Warrant,
whether in whole or in part, must be in compliance with Paragraph 12 of this
Warrant. Subject to the other terms and conditions of this Warrant, the Holder
is entitled to exercise this Warrant in whole or in part at any time, or from
time to time, until the Expiration Date or, if such day is not a Business Day,
then on the next succeeding day that shall be a Business Day. To exercise this
Warrant, the Holder shall execute and deliver to the Company a Warrant Exercise
Notice substantially in the form annexed hereto. Subject to paragraph 2(e)
below, no earlier than ten days after delivery of the Warrant Exercise Notice,
the Holder shall deliver to the Company this Warrant, including the Warrant
Exercise Subscription Form forming a part hereof duly executed by the Holder,
together with payment of the applicable Exercise Price. Upon such delivery and
payment, the Holder shall be deemed to be the holder of record of the Warrant
Shares subject to such exercise, notwithstanding that the stock transfer books
of the Company shall then be closed or that certificates representing such
Warrant Shares shall not then be actually delivered to the Holder.

          (b) The Exercise Price may be paid by wire transfer or by certified or
official bank check or bank cashier's check payable to the order of the Company
or by any combination of such cash or check.

          (c) If the Holder exercises this Warrant in part, this Warrant shall
be surrendered by the Holder to the Company and a new Warrant of the same tenor
and for the unexercised number of Warrant Shares shall be executed by the
Company. The Company shall register the new Warrant in the name of the Holder or
in such name or names of its transferee pursuant to paragraph 6 hereof as may be
directed in writing by the Holder and deliver the new Warrant to the Person or
Persons entitled to receive the same.

          (d) Upon exercise or partial exercise and surrender of this Warrant in
conformity with the foregoing provisions, the Company shall transfer to the
Holder of this Warrant appropriate evidence of ownership of the Common Shares or
other securities or property (including any money) to which the Holder is
entitled, registered or otherwise placed in, or payable to the order of, the
name or names of the Holder or such transferee as may be directed in writing by
the Holder, and shall deliver such evidence of ownership and any other
securities or

                                       3
<PAGE>   4

property (including any money) to the Person or Persons entitled to receive the
same, together with an amount in cash in lieu of any fraction of a share as
provided in paragraph 5 below.

          (e) In lieu of exercising the Warrant pursuant to paragraph 2(a), the
Holder may elect in accordance with the procedures set forth in this paragraph 2
to exchange this Warrant for shares of Common Stock, in which event the Company
will issue to the Holder the number of shares of Common Stock equal to the
result obtained by (a) subtracting B from A, (b) multiplying the difference by
C, and (c) dividing the product by A as set forth in the following equation:

                  X = (A - B) x C where:
                      -----------
                           A

                           X  =     the number of shares of Common Stock
                                    issuable upon exchange pursuant to this
                                    paragraph 2(e).

                           A  =     the Daily Price (as defined below) on the
                                    day immediately preceding the date on which
                                    the Holder delivers written notice to the
                                    Company pursuant to paragraph 2(a).

                           B  =     the Exercise Price.

                           C  =     the number of shares of Common Stock as to
                                    which this Warrant being exchanged would
                                    other be exercisable for pursuant to
                                    paragraph 2(a).

         If the foregoing calculation results in a negative number, then no
shares of Common Stock shall be issued pursuant to this paragraph 2(e).

          (f) Mandatory Exercise. (i) If at any time after the second
anniversary of the date of issuance of this Warrant the Daily Price for a Common
Share for each and every day of any period of 40 consecutive trading days
exceeds $24, then this Warrant shall be automatically exercised on a net
issuance basis in accordance with paragraph (e) above at the Exercise Price, as
adjusted, then in effect as of the close of business on the last trading day of
the 40 trading day period (a "MANDATORY EXERCISE EVENT") into Common Shares (or
other securities or property into which this Warrant is then convertible). This
Warrant as so exercised shall be treated as having been surrendered by the
Holder thereof for exercise pursuant to Section 2 as of the close of business on
the last trading day of the 40 trading day period.

                                       4
<PAGE>   5

         (ii) If the Company shall at any time after the date of issuance of
this Warrant pay any dividend on Common Shares payable in Common Shares or
effect a subdivision or combination of the outstanding Common Shares (by
reclassification, stock split or otherwise) into a greater or lesser number of
Common Shares, then the share price referred to in clause (i) above shall be
adjusted upon the earlier of the public announcement or the occurrence of any
such event by multiplying the share price by a fraction of which the numerator
is the number of Common Shares that were outstanding immediately prior to such
event and of which the denominator is the number of Common Shares outstanding
immediately after such event; provided, however, that if thereafter, and before
such dividend is paid or such subdivision or combination is effected, the
Company legally abandons its plan to pay such dividend or to effect such
subdivision or combination, then any adjustment made to such share price by
reason of such public announcement shall be reversed, and any subsequent
adjustments, based thereon, shall be recomputed.

           3. Restrictive Legend. Certificates representing Common Shares issued
pursuant to this Warrant shall bear a legend substantially in the form of the
legend set forth on the first page of this Warrant to the extent that and for so
long as such legend is required pursuant to the Investor Rights Agreement or
applicable law.

           4. Reservation of Shares. The Company hereby agrees that at all times
prior to the expiration hereof there shall be reserved for issuance and delivery
upon exercise or exchange of this Warrant such number of its authorized but
unissued Common Shares or other securities of the Company from time to time
issuable upon the full exercise of the then unexercised portion of this Warrant.
All such shares shall be duly authorized and, when issued upon such exercise or
exchange, shall be validly issued, fully paid and non-assessable, free and clear
of all liens, security interests, charges and other encumbrances or restrictions
on sale and free and clear of all preemptive rights, except to the extent set
forth in the Investor Rights Agreement and as may be required under applicable
law.

           5. Fractional Shares. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise or exchange of this Warrant
and in lieu of delivery of any such fractional share upon any exercise hereof,
the Company shall pay to the Holder an amount in cash equal to such fraction
multiplied by the Current Market Price Per Common Share (as defined in paragraph
8(g)) at the date of such exercise or exchange.

           6.   Transfer or Assignment of Warrant.

          (a) This Warrant and all rights hereunder are not transferable by the
registered Holder hereof except to any Person who, prior to such transfer,
agrees in writing, in form and substance reasonably satisfactory to the Company,
to be

                                       5
<PAGE>   6

bound by the terms of this Warrant and the Investor Rights Agreement in
accordance with the provisions hereof and thereof. Each Holder of this Warrant
by taking or holding the same, consents and agrees that the registered Holder
hereof may be treated by the Company and all other persons dealing with this
Warrant as the absolute owner hereof for any purpose and as the person entitled
to exercise the rights represented hereby.

          (b) Subject to compliance with the terms of this Warrant and the
Investor Rights Agreement, the Holder of this Warrant shall be entitled, without
obtaining the consent of the Company to assign and transfer this Warrant, at any
time in whole or from time to time in part, to any Person or Persons. Subject to
the preceding sentence, upon surrender of this Warrant to the Company, together
with the attached Warrant Assignment Form duly executed, the Company shall,
without charge, execute and deliver a new Warrant for the Common Shares assigned
in the Warrant Form Assignment in the name of the assignee or assignees named in
such instrument of assignment and, if the Holder's entire interest is not being
assigned, a new Warrant for the balance of the Common Shares for which this
Warrant is then exercisable which are not so assigned in the name of the Holder
and this Warrant shall promptly be canceled.

           7. Loss or Destruction of Warrant. Upon receipt by the Company of
evidence satisfactory to it (in the exercise of its reasonable discretion) of
the loss, theft, destruction or mutilation of this Warrant, and (in the case of
loss, theft or destruction) of reasonably satisfactory indemnification, and upon
surrender and cancellation of this Warrant, if mutilated, the Company shall
execute and deliver to the Holder a new Warrant of like tenor and date.

           8. Anti-dilution Provisions.

          (a) In case the Company shall at any time after the date hereof (i)
declare a dividend or make a distribution on Common Shares payable in Common
Shares, (ii) subdivide or split the outstanding Common Shares, (iii) combine or
reclassify the outstanding Common Shares into a smaller number of shares, or
(iv) issue any shares of its capital stock in a reclassification of Common
Shares (including any such reclassification in connection with a consolidation
or merger in which the Company is the continuing corporation), the Exercise
Price in effect at the time of the record date for such dividend or distribution
or of the effective date of such subdivision, split, combination or
reclassification shall be proportionately adjusted so that, giving effect to
paragraph 8(i), the exercise of this Warrant after such time shall entitle the
Holder to receive the aggregate number of Common Shares or other securities of
the Company (or shares of any security into which such Common Shares have been
reclassified pursuant to clause 8(a)(iii) or 8(a)(iv) above) which, if this
Warrant had been exercised immediately prior to such time, the Holder would have
owned upon such exercise and been entitled to receive by

                                       6
<PAGE>   7

virtue of such dividend, distribution, subdivision, split, combination or
reclassification. Such adjustment shall be made successively whenever any event
listed above shall occur.

          (b) In case the Company shall issue or sell any Common Shares (other
than Common Shares issued (i) upon exercise of the Warrants or conversion of the
Series A Convertible Participating Preferred Shares of the Company (the
"PREFERRED SHARES"), (ii) pursuant to the Company's stock option plans or
pursuant to any similar Common Share related employee compensation plan of the
Company approved by the Company's Board of Directors or (iii) upon exercise or
conversion of any security the issuance of which caused an adjustment under
paragraphs 8(c) or 8(d) hereof) without consideration or for a consideration per
share less than the Exercise Price (the "ISSUE PRICE"), the Exercise Price to be
in effect after such issuance or sale shall be determined by multiplying the
Exercise Price in effect immediately prior to such issuance or sale by a
fraction, the numerator of which shall be the sum of (x) the number of Common
Shares outstanding immediately prior to the time of such issuance or sale
multiplied by the Issue Price and (y) the aggregate consideration, if any, to be
received by the Company upon such issuance or sale, and the denominator of which
shall be the product of the aggregate number of Common Shares outstanding
immediately after such issuance or sale and the Exercise Price. In case any
portion of the consideration to be received by the Company shall be in a form
other than cash, the fair market value of such noncash consideration shall be
utilized in the foregoing computation. Such fair market value shall be
determined by the Board of Directors of the Company; provided that if the
Holders of 75% of the outstanding Warrants shall object to any such
determination, the Board of Directors shall retain an independent appraiser
reasonably satisfactory to a majority of such Holders to determine such fair
market value. The Holder shall be notified promptly of any consideration other
than cash to be received by the Company and furnished with a description of the
consideration and the fair market value thereof, as determined by the Board of
Directors.

          (c) In case the Company shall fix a record date for the issuance of
rights, options or warrants to the holders of its Common Shares or other
securities entitling such holders to subscribe for or purchase for a period
expiring within 60 days of such record date Common Shares (or securities
convertible into Common Shares) at a price per Common Share (or having a
conversion price per Common Share, if a security convertible into Common Shares)
less than the Exercise Price on such record date, the maximum number of Common
Shares issuable upon exercise of such rights, options or warrants (or conversion
of such convertible securities) shall be deemed to have been issued and
outstanding as of such record date and the Exercise Price shall be adjusted
pursuant to paragraph 8(b) hereof, as though such maximum number of Common
Shares had been so issued for an

                                       7
<PAGE>   8

aggregate consideration payable by the holders of such rights, options, warrants
or convertible securities prior to their receipt of such Common Shares. In case
any portion of such consideration shall be in a form other than cash, the fair
market value of such noncash consideration shall be determined as set forth in
paragraph 8(b) hereof. Such adjustment shall be made successively whenever such
record date is fixed; and in the event that such rights, options or warrants are
not so issued or expire unexercised, or in the event of a change in the number
of Common Shares to which the holders of such rights, options or warrants are
entitled (other than pursuant to adjustment provisions therein comparable to
those contained in this paragraph 8), the Exercise Price shall again be adjusted
to be the Exercise Price which would then be in effect if such record date had
not been fixed, in the former event, or the Exercise Price which would then be
in effect if such holder had initially been entitled to such changed number of
Common Shares, in the latter event.

          (d) In case the Company shall issue rights, options (other than
options issued pursuant to a plan described in clause 8(b)(i)) or warrants
entitling the holders thereof to subscribe for or purchase Common Shares (or
securities convertible into Common Shares) or shall issue convertible securities
(other than the Preferred Shares), and the price per Common Share of such
rights, options, warrants or convertible securities (including, in the case of
rights, options or warrants, the price at which they may be exercised) is less
than the Exercise Price, the maximum number of Common Shares issuable upon
exercise of such rights, options or warrants or upon conversion of such
convertible securities shall be deemed to have been issued and outstanding as of
the date of such sale or issuance, and the Exercise Price shall be adjusted
pursuant to paragraph 8(b) hereof as though such maximum number of Common Shares
had been so issued for an aggregate consideration equal to the aggregate
consideration payable by the holders of such rights, options, warrants or
convertible securities prior to their receipt of such Common Shares. In case any
portion of such consideration shall be in a form other than cash, the fair
market value of such noncash consideration shall be determined as set forth in
paragraph 8(b) hereof. Such adjustment shall be made successively whenever such
rights, options, warrants or convertible securities are issued; and in the event
that such rights, options or warrants expire unexercised, or in the event of a
change in the number of Common Shares to which the holders of such rights,
options, warrants or convertible securities are entitled (other than pursuant to
adjustment provisions therein comparable to those contained in this paragraph
8), the Exercise Price shall again be adjusted to be the Exercise Price which
would then be in effect if such rights, options, warrants or convertible
securities had not been issued, in the former event, or the Exercise Price which
would then be in effect if such holders had initially been entitled to such
changed number of Common Shares, in the latter event. No adjustment of the
Exercise Price shall be made pursuant to this paragraph 8(d) to the extent that
the Exercise Price shall have been adjusted pursuant to paragraph 8(c) upon the

                                       8
<PAGE>   9

setting of any record date relating to such rights, options, warrants or
convertible securities and such adjustment fully reflects the number of Common
Shares to which the holders of such rights, options, warrants or convertible
securities are entitled and the price payable therefor.

          (e) In case the Company shall fix a record date for the making of a
dividend or distribution to holders of Common Shares (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing corporation) of evidences of indebtedness, cash,
assets or other property (other than regular periodic dividends payable in cash
or Common Shares or rights, options or warrants referred to in, and for which an
adjustment is made pursuant to, paragraph 8(c) hereof), the Exercise Price to be
in effect after such record date shall be determined by multiplying the Exercise
Price in effect immediately prior to such record date by a fraction, the
numerator of which shall be the Current Market Price Per Common Share on such
record date, less the fair market value (determined as set forth in paragraph
8(b) hereof) of the portion of the assets, other property or evidence of
indebtedness so to be distributed which is applicable to one Common Share, and
the denominator of which shall be such Current Market Price Per Common Share.
Such adjustments shall be made successively whenever such a record date is
fixed; and in the event that such distribution is not so made, the Exercise
Price shall again be adjusted to be the Exercise Price which would then be in
effect if such record date had not been fixed.

          (f) If the average (weighted by daily trading volume) of the Daily
Prices (as defined below) per Common Share for the 40 consecutive trading days
immediately preceding the fourth anniversary of the date of issuance of the
Series A Preferred Shares (the "AVERAGE WEIGHTED PRICE") is less than $15.00
then the Exercise Price then in effect shall be reduced to the greater of (i)
the Average Weighted Price and (ii) 75% of the Exercise Price.

          (g) For the purpose of any computation under paragraph 5 or paragraph
8(b), 8(c), 8(d), 8(e) or 8(f) hereof, on any determination date the "CURRENT
MARKET PRICE PER COMMON SHARE" shall be deemed to be the average (weighted by
daily trading volume) of the Daily Prices (as defined below) per share of the
applicable class of Common Shares for the 20 consecutive trading days
immediately prior to such date. "DAILY PRICE" means (A) if such Common Shares
then are listed and traded on the New York Stock Exchange, Inc. ("NYSE"), the
closing price per share on such day as reported on the NYSE Composite
Transactions Tape; (B) if the shares of such class of Common Shares then are not
listed and traded on the NYSE, the closing price per share on such day as
reported by the principal national securities exchange on which the shares are
listed and traded; (C) if such Common Shares then are not listed and traded on
any such

                                       9
<PAGE>   10

securities exchange, the last reported sale price per share on such day on the
NASDAQ Stock Market; or (D) if such Common Shares then are not traded on the
NASDAQ Stock Market, the average of the highest reported bid and lowest reported
asked price per share on such day as reported by NASDAQ. If on any determination
date such Common Shares are not quoted by any such organization, the Current
Market Price Per Common Share shall be the fair market value of such shares on
such determination date as determined by the Board of Directors of the Company.
If the Holders of 75% of the outstanding Warrants shall object to any
determination by the Board of Directors of the Company of the Current Market
Price Per Common Share, the Current Market Price Per Common Share shall be the
fair market value per share of the Common Shares as determined by an independent
appraiser retained by the Company at its expense and reasonably acceptable to
such Holders. For purposes of any computation under this paragraph 8, the number
of shares of Common Shares outstanding at any given time shall not include
shares owned or held by or for the account of the Company.

          (h) All calculations under this paragraph 8 shall be made to the
nearest one tenth of a cent or to the nearest hundredth of a share, as the case
may be.

          (i) In the event that, at any time as a result of the provisions of
this paragraph 8, the holder of this Warrant upon subsequent exercise or
exchange shall become entitled to receive any shares of capital stock of the
Company other than Common Shares, the number of such other shares so receivable
upon exercise or exchange of this Warrant shall thereafter be subject to
adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions contained herein.

          (j) Upon each adjustment of the Exercise Price as a result of the
calculations made in paragraphs 8(a), 8(b), 8(c), 8(d) or 8(e) hereof, the
number of shares for which this Warrant is exercisable immediately prior to the
making of such adjustment shall thereafter evidence the right to purchase, at
the adjusted Exercise Price, that number of Common Shares obtained by (i)
multiplying the number of shares covered by this Warrant immediately prior to
this adjustment of the number of shares by the Exercise Price in effect
immediately prior to such adjustment of the Exercise Price and (ii) dividing the
product so obtained by the Exercise Price in effect immediately after such
adjustment of the Exercise Price.

          (k) If the Company shall fix a record date relating to the payment of
a dividend or other distribution or the issuance of rights, options or warrants
as contemplated under this paragraph 8 (which results in an adjustment to the
Exercise Price under the terms of this Warrant) and shall thereafter, and before
such dividend or distribution is paid or delivered or before such issuance,
legally abandon its plan to pay or deliver such dividend or distribution or to
make such issuance, then any adjustment made to the Exercise Price and number of
Common

                                       10
<PAGE>   11
Shares purchasable upon exercise of this Warrant by reason of the fixing of such
record date shall be reversed, and any subsequent adjustments, based thereon,
shall be recomputed.

           9. Consolidation, Merger, or Sale of Assets. In case of any
consolidation of the Company with, or merger of the Company into, any other
Person, any merger of another Person into the Company (other than a merger which
does not result in any reclassification, conversion, exchange or cancellation of
outstanding Common Shares) or any sale or transfer of all or substantially all
of the assets of the Company or of the Person formed by such consolidation or
resulting from such merger or which acquires such assets, as the case may be,
the Holder shall have the right thereafter to exercise or exchange this Warrant
for the kind and amount of securities, cash and other property receivable upon
such consolidation, merger, sale or transfer by a holder of the number of Common
Shares for which this Warrant may have been exercised or exchanged immediately
prior to such consolidation, merger, sale or transfer, assuming (i) such holder
of Common Shares is not a Person with which the Company consolidated or into
which the Company merged or which merged into the Company or to which such sale
or transfer was made, as the case may be ("CONSTITUENT PERSON"), or an Affiliate
of a Constituent Person and (ii) in the case of a consolidation merger, sale or
transfer which includes an election as to the consideration to be received by
the holders, such holder of Common Shares failed to exercise such rights of
election, as to the kind or amount of securities, cash and other property
receivable upon such consolidation, merger, sale or transfer (provided that if
the kind or amount of securities, cash and other property receivable upon such
consolidation, merger, sale or transfer is not the same for each Common Share
held immediately prior to such consolidation, merger, sale or transfer by other
than a Constituent Person or an Affiliate thereof and in respect of which such
rights of election shall not have been exercised ("NON-ELECTING SHARE"), then
for the purpose of this paragraph 9 the kind and amount of securities, cash and
other property receivable upon such consolidation, merger, sale or transfer by
each non-electing share shall be deemed to be the kind and amount so receivable
per share by a plurality of the non-electing shares). Adjustments for events
subsequent to the effective date of such a consolidation, merger or sale of
assets shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Warrant. In any such event, effective provisions shall be
made in the certificate or articles of incorporation of the resulting or
surviving corporation, in any contract of sale, conveyance, lease or transfer,
or otherwise so that the provisions set forth herein for the protection of the
rights of the Holder shall thereafter continue to be applicable; and any such
resulting or surviving corporation shall expressly assume the obligation to
deliver, upon exercise or exchange, such shares of stock, other securities, cash
and property. The provisions of this paragraph 9 shall similarly apply to
successive

                                       11

consolidations, mergers, sales or transfers. For purposes of this paragraph 9,
"Person" shall not include any entity of which securities or other ownership
interests having ordinary voting power to elect a majority of the board of
directors or other persons performing similar functions are owned directly or
indirectly by the Company.

          10. Notices. Any notice, request, demand or delivery authorized by

<PAGE>   13

                  (a) Such transferee is an "accredited investor" within the
         meaning of Rule 501 under the 1933 Act and such transferee was not
         organized for the specific purpose of acquiring this Warrant or the

                  (b) such transferee has sufficient knowledge and experience in
         investing in companies similar to the Company so as to be able to
         evaluate the risks and merits of such transferee's investment in the
         Company and is able financially to bear the risks thereof;

                  (c) such transferee has had an opportunity to obtain whatever
         information concerning the Company and the Common Shares as has been
         requested from the Company by such transferee in order to make such
         transferee's investment decision with respect to this Warrant and the
         Common Shares;

                  (d) this Warrant is being acquired by such transferee for such
         transferee's own account for the purpose of investment and not with a
         view to or for sale in connection with any distribution thereof; and

                  (e) such transferee understands that (i) this Warrant and the
         Common Shares issuable upon exercise of this Warrant have not been
         registered under the Securities Act of 1933, as amended, in reliance
         upon an exemption from the registration requirements of such act
         pursuant to Section 4(2) thereof or Rule 506 promulgated under such act
         and under applicable state securities laws, (ii) this Warrant and the
         Common Shares issuable upon exercise of this Warrant must be held
         indefinitely unless a subsequent disposition thereof is registered
         under such act and under applicable state securities laws or is exempt
         from such registration, (iii) this Warrant and the Common Shares
         issuable upon exercise of this Warrant will bear a legend to such
         effect, and (iv) the Company will make a notation on its transfer books
         to such effect.

          13. GOVERNING LAW. THIS WARRANT AND ALL RIGHTS ARISING HEREUNDER SHALL
BE CONSTRUED AND DETERMINED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF
OHIO, AND THE PERFORMANCE THEREOF SHALL BE GOVERNED AND ENFORCED IN ACCORDANCE
WITH SUCH LAWS.

          14. Amendments; Waivers. Any provision of this Warrant may be amended
or waived if, and only if, such amendment or waiver is in writing and signed, in
the case of an amendment, by the Holder and the Company, or in the case of a
waiver, by the party against whom the waiver is to be effective. No

                                       13

failure or delay by either party in exercising any right, power or privilege
hereunder shall operate as a waiver thereof nor shall any single or partial
exercise thereof preclude any other or further exercise thereof or the exercise
of any other right, power or privilege. The rights and remedies herein provided
shall be cumulative and not exclusive of any rights or remedies provided by law.
