effect, if it should be determined that any such provision would prevent a
proposed merger or other business combination that is intended by the parties
thereto (which may include either or both of the Parent and the Corporation) to
be accounted for as a pooling of interests from being so accounted for.

        (h)     Option Rights granted pursuant to this Section 4 may be
Nonqualified Options or Tax-Qualified Options or combinations thereof.

                                       9
<PAGE>   10

        (i)     On or after the Date of Grant of any Nonqualified Option, the
Board may provide for the payment to the Optionee of dividend equivalents
thereon in cash or Class A Common Shares or Class B Common Shares on a current,
deferred or contingent basis, or the Board may provide that any dividend
equivalents shall be credited against the Option Price.

        (j)     No Option Right granted pursuant to this Section 4 may be
exercised more than 10 years from the Date of Grant.

        (k)     Each grant shall be evidenced by an agreement that shall be
executed on behalf of the Corporation by any officer thereof and delivered to
and accepted by the Optionee and shall contain such terms and provisions as the
Board may determine consistent with this Plan.

        5.      Appreciation Rights. The Board may authorize grants to
Participants of Appreciation Rights. An Appreciation Right shall be a right of
the Participant to receive from the Corporation an amount that shall be
determined by the Board and shall be expressed as a percentage (not exceeding
100 percent) of the Spread at the time of the exercise of the Appreciation
Right. Any grant of Appreciation Rights under this Plan shall be upon such terms
and conditions as the Board may determine in accordance with the following
provisions:

        (a)     Any grant may specify that the amount payable upon the exercise
of an Appreciation Right may be paid by the Corporation in cash, Class A Common
Shares, Class B Common Shares or any combination thereof and may (i) either
grant to the Participant or reserve to the Board the right to elect among those
alternatives or (ii) preclude the right of the Participant to receive and the
Corporation to issue Common Shares or other equity securities in lieu of cash;
provided, however, that no form of consideration or manner of payment that would
cause Rule 16b-3 to cease to apply to this Plan shall be permitted.

        (b)     Any grant shall specify that no amount payable upon the exercise
of an Appreciation Right shall be required to be paid to the extent that such
payment would not be permitted under, or would constitute a breach or violation
of, any indenture, loan agreement or other instrument or agreement to which the
Corporation is a party or by which it is bound, and also may specify that the
amount payable upon the exercise of an Appreciation Right shall not exceed a
maximum specified by the Board on the Date of Grant.

        (c)     Any grant may specify (i) a waiting period or periods before
Appreciation Rights shall become exercisable and (ii) permissible dates or
periods on or during which Appreciation Rights shall be exercisable.

        (d)     Any grant may specify that an Appreciation Right may be
exercised only in the event of a Change of Control or other similar transaction
or event.

        (e)     On or after the Date of Grant of any Appreciation Rights, the
Board may provide for the payment to the Participant of dividend equivalents
thereon in cash, Class A Common Shares or Class B Common Shares on a current,
deferred or contingent basis.

        (f)     Each grant shall be evidenced by an agreement that shall be
executed on behalf of the Corporation by any officer thereof and delivered to
and accepted by the Participant and shall contain such terms and provisions as
the Board may determine consistent with this Plan.

                                       10
<PAGE>   11

        (g)     Regarding Tandem Appreciation Rights only: Each grant shall
specifically identify the related Option Right (or similar right granted under
any other plan of the Corporation) and shall provide that the Tandem
Appreciation Right may be exercised only (i) at a time when the related Option
Right (or such similar right) is also exercisable and the Spread is positive and
(ii) by surrender of the related Option Right (or such similar right) for
cancellation.

        (h)     Regarding Free-Standing Appreciation Rights only:

                (i)     Each grant shall specify in respect of each
Free-Standing Appreciation Right a Base Price per Common Share, which shall be
equal to or greater than the Market Value per Share on the Date of Grant;

                (ii)    Successive grants may be made to the same Participant
regardless of whether any Free-Standing Appreciation Rights previously granted
to the Participant remain unexercised;

                (iii)   Each grant shall specify the period or periods of
continuous employment of the Participant by the Corporation or any Subsidiary
that are necessary before the Free-Standing Appreciation Rights or installments
thereof shall become exercisable, and any grant may provide for the earlier
exercise of the Free-Standing Appreciation Rights in the event of a Change of
Control or other similar transaction or event; and

                (iv)    No Free-Standing Appreciation Right granted under this
Plan may be exercised more than 10 years from the Date of Grant.

        6.      Restricted Shares. The Board may authorize grants or sales to
Participants of Restricted Shares upon such terms and conditions as the Board
may determine in accordance with the following provisions:

        (a)     Each grant or sale shall constitute an immediate transfer of the
ownership of Common Shares to the Participant in consideration of the
performance of services, entitling such Participant to dividend, voting and
other ownership rights, subject to the substantial risk of forfeiture and
restrictions on transfer hereinafter referred to.

        (b)     Each grant or sale may be made without additional consideration
from the Participant or in consideration of a payment by the Participant that is
less than the Market Value per Share on the Date of Grant.

        (c)     Each grant or sale shall provide that the Restricted Shares
covered thereby shall be subject to a "substantial risk of forfeiture" within
the meaning of Section 83 of the Code for a period to be determined by the Board
on the Date of Grant, and any grant or sale may provide for the earlier
termination of such period in the event of a Change of Control or other similar
transaction or event.

        (d)     Each grant or sale shall provide that, during the period for
which such substantial risk of forfeiture is to continue, the transferability of
the Restricted Shares shall be prohibited or restricted in the manner and to the
extent prescribed by the Board on the Date of Grant. Such restrictions may
include without limitation rights of repurchase or first refusal in the
Corporation

                                       11
<PAGE>   12

or provisions subjecting the Restricted Shares to a continuing substantial risk
of forfeiture in the hands of any transferee.

        (e)     Any grant or sale may require that any or all dividends or other
distributions paid on the Restricted Shares during the period of such
restrictions be automatically sequestered and reinvested on an immediate or
deferred basis in additional Class A Common Shares or Class B Common Shares,
which may be subject to the same restrictions as the underlying award or such
other restrictions as the Board may determine.

        (f)     Each grant or sale shall be evidenced by an agreement that shall
be executed on behalf of the Corporation by any officer thereof and delivered to
and accepted by the Participant and shall contain such terms and provisions as
the Board may determine consistent with this Plan. Unless otherwise directed by
the Board, all certificates representing Restricted Shares, together with a
stock power that shall be endorsed in blank by the Participant with respect to
the Restricted Shares, shall be held in custody by the Corporation until all
restrictions thereon lapse.

        7.      Deferred Shares. The Board may authorize grants or sales of
Deferred Shares to Participants upon such terms and conditions as the Board may
determine in accordance with the following provisions:

        (a)     Each grant or sale shall constitute the agreement by the
Corporation to issue or transfer Common Shares to the Participant in the future
in consideration of the performance of services, subject to the fulfillment
during the Deferral Period of such conditions as the Board may specify.

        (b)     Each grant or sale may be made without additional consideration
from the Participant or in consideration of a payment by the Participant that is
less than the Market Value per Share on the Date of Grant.

        (c)     Each grant or sale (i) shall provide that the Deferred Shares
covered thereby shall be subject to a Deferral Period, which shall be determined
by the Board on the Date of Grant, and (ii), unless otherwise expressly
determined in a resolution duly adopted by the Board on the Date of Grant or
such later date on which the Board may ratify such grant or sale, shall provide
for the earlier termination of the Deferral Period, and the immediate vesting of
the Participant's rights to all of the Deferred Shares subject to the grant or
sale, (1) if the Participant is a Nonaffiliate Director, upon the occurrence of
a Change of Control of the Corporation or (2) if the Participant is recognized
by any Employer as a regular full time employee, upon the termination of the
Participant's employment by an Employer without Cause during the Accelerated
Vesting Period and also, in the case of a Participant who is an Executive, upon
the termination of the Participant's employment by the Participant for Good
Reason during the Accelerated Vesting Period; provided, however, that any such
Accelerated Vesting Provision shall be deemed void ab initio and shall be of no
force or effect, if it should be determined that any such provision would
prevent a proposed merger or other business combination that is intended by the
parties thereto (which may include either or both of the Parent and the
Corporation) to be accounted for as a pooling of interests from being so
accounted for.

                                       12
<PAGE>   13

        (d)     During the Deferral Period, the Participant shall not have any
rights of ownership in the Deferred Shares, shall not have any right to vote the
Deferred Shares and, except as provided in Section 11(c), shall not have any
right to transfer any rights under the subject award, but the Board may on or
after the Date of Grant authorize the payment of dividend equivalents on the
Deferred Shares in cash or additional Class A Common Shares or Class B Common
Shares on a current, deferred or contingent basis.

        (e)     Each grant or sale shall be evidenced by an agreement that shall
be executed on behalf of the Corporation by any officer thereof and delivered to
and accepted by the Participant and shall contain such terms and provisions as
the Board may determine consistent with this Plan.

        8.      Performance Shares and Performance Units. The Board may
authorize grants of Performance Shares and Performance Units, which shall become
payable to the Participant upon the achievement of specified Management
Objectives, upon such terms and conditions as the Board may determine in
accordance with the following provisions:

        (a)     Each grant shall specify the number of Performance Shares or
Performance Units to which it pertains, which may be subject to adjustment to
reflect changes in compensation or other factors.

        (b)     The Performance Period with respect to each Performance Share or
Performance Unit (i) shall be determined by the Board on the Date of Grant and
(ii), unless otherwise expressly determined in a resolution duly adopted by the
Board on the Date of Grant or such later date on which the Board may ratify such
grant, shall provide for the earlier termination of the Performance Period, and
the immediate vesting of the Participant's rights to all of the Performance
Shares or Performance Units subject to the grant, (1) if the Participant is a
Nonaffiliate Director, upon the occurrence of a Change of Control of the
Corporation or (2) if the Participant is recognized by any Employer as a regular
full time employee, upon the termination of the Participant's employment by an
Employer without Cause during the Accelerated Vesting Period and also, in the
case of a Participant who is an Executive, upon the termination of the
Participant's employment by the Participant for Good Reason during the
Accelerated Vesting Period; provided, however, that any such Accelerated Vesting
Provision shall be deemed void ab initio and shall be of no force or effect, if
it should be determined that any such provision would prevent a proposed merger
or other business combination that is intended by the parties thereto (which may
include either or both of the Parent and the Corporation) to be accounted for as
a pooling of interests from being so accounted for.

        (c)     Each grant shall specify the Management Objectives that are to
be achieved by the Participant, which may be described in terms of
Corporation-wide objectives or objectives that are related to the performance of
the individual Participant or the Subsidiary, division, department or function
within the Corporation or Subsidiary in which the Participant is employed or
with respect to which the Participant provides consulting services.

        (d)     Each grant shall specify in respect of the specified Management
Objectives a minimum acceptable level of achievement below which no payment will
be made and shall set forth a formula for determining the amount of any payment
to be made if performance is at or

                                       13
<PAGE>   14

above the minimum acceptable level but falls short of full achievement of the
specified Management Objectives.

        (e)     Each grant shall specify the time and manner of payment of
Performance Shares or Performance Units that shall have been earned, and any
grant may specify that any such amount may be paid by the Corporation in cash,
Class A Common Shares or Class B Common Shares or any combination thereof and
may either grant to the Participant or reserve to the Board the right to elect
among those alternatives; provided, however, that no form of consideration or
manner of payment that would cause Rule 16b-3 to cease to apply to this Plan
shall be permitted.

        (f)     Any grant of Performance Shares shall specify that no amount
payable with respect thereto shall be required to be paid to the extent that
such payment would not be permitted under, or would constitute a breach or
violation of, any indenture, loan agreement or other instrument or agreement to
which the Corporation is a party, or by which it is bound, and also may specify
that the amount payable with respect thereto may not exceed a maximum specified
by the Board on the Date of Grant. Any grant of Performance Units shall specify
that no amount payable with respect thereto shall be required to be paid to the
extent that such payment would not be permitted under, or would constitute a
breach or violation or, any indenture, loan agreement or other instrument or
agreement to which the Corporation is a party or by which it is bound, and also
may specify that the amount payable, or the number of Common Shares issuable,
with respect thereto may not exceed a maximum specified by the Board on the Date
of Grant.

        (g)     On or after the Date of Grant of Performance Shares, the Board
may provide for the payment to the Participant of dividend equivalents thereon
in cash or additional Class A Common Shares or Class B Common Shares on a
current, deferred or contingent basis.

        (h)     The Board may adjust Management Objectives and the related
minimum acceptable level of achievement if, in the sole judgment of the Board,
events or transactions have occurred after the Date of Grant that are unrelated
to the performance of the Participant and result in distortion of the Management
Objectives or the related minimum acceptable level of achievement.

        (i)     Each grant shall be evidenced by an agreement that shall be
executed on behalf of the Corporation by any officer thereof and delivered to
and accepted by the Participant and shall contain such terms and provisions as
the Board may determine consistent with this Plan.

        9.      Corporation's Repurchase Right. Upon cessation of a
Participant's employment with the Corporation, Subsidiary or Designated
Affiliate prior to the Initial Public Offering, regardless of the circumstances
thereof, and including without limitation upon death, disability, retirement,
discharge or resignation for any reason or no reason, and whether voluntary or
involuntarily, the Corporation, or an assignee of the Corporation, shall have
the right to repurchase from the Participant (or, (i) if the Participant is then
deceased, from the Participant's estate or (ii) if the Participant has
transferred shares pursuant to Section 11(d), from the Participant's transferee
(a "Permitted Transfer")) any and all Common Shares that are to be, or have
been, issued or transferred by the Corporation upon the exercise of Option
Rights or Appreciation Rights, upon the termination of the Deferral Period
applicable to Deferred Shares

                                       14
<PAGE>   15

or upon payment under any grant of Performance Shares or Performance Units, or
are to be no longer subject to the substantial risk of forfeiture and
restrictions on transfer referred to in Section 6 of this Plan then held by the
Participant (or his or her estate or his or her Permitted Transferee) at a
repurchase price per Common Share equal to the Market Value per Share on the
date of repurchase; provided, however, that this repurchase right initially
applies only to Common Shares that have been held by a Participant for more than
six months as of the date of cessation of the Participant's employment and, with
respect to Common Shares that have not been held for more than six months, shall
be extended to the date six months after the date upon which such shares are
acquired. The Corporation may exercise its repurchase right by paying to the
Participant (or his or her estate or his or her Permitted Transferee) the
aggregate amount of such repurchase price in cash within 30 days following the
date of such cessation of the Participant's employment (or following the date
upon which the Common Shares have been held for six months, if later), and the
Participant (or his or her estate or his or her Permitted Transferee) shall
endorse and deliver to the Corporation the certificate(s) representing the
Common Shares so repurchased. Until the consummation of an Initial Public
Offering, certificates representing all such Common Shares issued to
Participants under the Plan, together with a stock power that shall be endorsed
in blank by the Participant, shall be held in custody by the Corporation.

        10.     First Refusal Rights; Market Stand-Off.

        (a)     Prior to the Initial Public Offering, the Corporation shall have
the right of first refusal with respect to any proposed sale or other
disposition by the holder of any Common Shares that are to be, or have been,
issued or transferred by the Corporation upon the exercise of Option Rights or
Appreciation Rights, upon the termination of the Deferral Period applicable to
Deferred Shares or upon payment under any grant of Performance Shares or
Performance Units, or are to be no longer subject to the substantial risk of
forfeiture and restrictions on transfer referred to in Section 6 of this Plan.
Such right of first refusal shall be exercisable in accordance with the terms
and conditions set forth in the agreement evidencing such award; provided,
however, that this right of first refusal applies only to Common Shares that
have been held by a Participant for more than six months.

        (b)     In connection with any underwritten public offering by the
Corporation of its equity securities pursuant to an effective registration
statement filed under the Securities Act, including the Initial Public Offering,
a person shall not sell, or make any short sale of, loan, hypothecate, pledge,
grant any option for the purchase of, or otherwise dispose or transfer for value
or otherwise agree to engage in any of the foregoing transactions with respect
to, any Common Shares that are to be, or have been, issued or transferred by the
Corporation upon the exercise of Option Rights or Appreciation Rights, upon the
termination of the Deferral Period applicable to Deferred Shares or upon payment
under any grant of Performance Shares or Performance Units, or are to be no
longer subject to the substantial risk of forfeiture and restrictions on
transfer referred to in Section 6 of this Plan without the prior written consent
of the Corporation or its underwriters.

                                       15

<PAGE>   16

        11.     Transferability.

        (a)     Except as otherwise determined by the Board, no Option Right,
Appreciation Right or other derivative security granted under this Plan shall be
transferable by a Participant other than by will or the laws of descent and
distribution and, except as otherwise determined by the Board, Option Rights and
Appreciation Rights shall be exercisable during a Participant's lifetime only by
the Participant or his or her guardian or legal representative.

        (b)     Prior to the Initial Public Offering, no holder of any Common
Shares that have been issued or transferred by the Corporation upon the exercise
of Option Rights or Appreciation Rights, upon the termination of the Deferral
Period applicable to Deferred Shares, upon payment under any grant of
Performance Shares or Performance Units, or are no longer subject to the
substantial risk of forfeiture and restrictions on transfer referred to in
Section 6 of this Plan, shall sell or transfer such Common Shares during a
period of six months following their issue or transfer by the Corporation in
order to permit the Corporation to exercise the right of first refusal described
in Section 10(a) of this Plan.

        (c)     The Board also may specify at the Date of Grant that all or any
part of the Common Shares that are to be issued or transferred by the
Corporation upon the exercise of Option Rights or Appreciation Rights, upon the
termination of the Deferral Period applicable to Deferred Shares or upon payment
under any grant of Performance Shares or Performance Units, or are to be no
longer subject to the substantial risk of forfeiture and restrictions on
transfer referred to in Section 6 of this Plan, shall be subject to further
restrictions on transfer.

        (d)     Notwithstanding the provisions of Section 11(a), Option Rights
(other than Incentive Stock Options), Appreciation Rights, Restricted Shares,
Deferred Shares, Performance Shares and Performance Units shall be transferable
by a Participant, without payment of consideration therefor by the transferee,
to any one or more members of the Participant's Immediate Family (or to one or
more trusts established solely for the benefit of one or more members of the
Participant's Immediate Family or to one or more partnerships in which the only
partners are members of the Participant's Immediate Family); provided, however,
that (i) no such transfer shall be effective unless reasonable prior notice
thereof is delivered to the Corporation and such transfer is thereafter effected
in accordance with any terms and conditions that shall have been made applicable
thereto by the Corporation or the Board and (ii) any such transferee shall be
subject to the same terms and conditions hereunder as the Participant.

        12.     Adjustments. The Board may make or provide for such adjustments
in the number of Common Shares covered by outstanding Option Rights,
Appreciation Rights, Deferred Shares and Performance Shares granted hereunder,
the Option Prices per Common Share or Base Prices per Common Share applicable to
any such Option Rights and Appreciation Rights, and the kind of shares
(including shares of another issuer) covered thereby, as the Board may in good
faith determine to be equitably required in order to prevent dilution or
expansion of the rights of Participants that otherwise would result from (a) any
stock dividend, stock split, combination of shares, recapitalization or other
change in the capital structure of the Corporation or (b) any merger,
consolidation, spin-off, spin-out, split-off, split-up, reorganization, partial
or complete liquidation or other distribution of assets, issuance of warrants or
other rights to purchase securities or any other corporate transaction or event
having an effect similar to any of

                                       16

<PAGE>   17
the foregoing. In the event of any such transaction or event, the Board may
provide in substitution for any or all outstanding awards under this Plan such
alternative consideration as it may in good faith determine to be equitable
under the circumstances and may require in connection therewith the surrender of
all awards so replaced. On or after the Date of Grant of any award under this
Plan, the Board may provide in the agreement evidencing the award that the
holder of the award may elect to receive an equivalent award in respect of
securities of the surviving entity of any merger, consolidation or other
transaction or event having a similar effect, or the Board may provide that the
holder will automatically be entitled to receive such an equivalent award. The
Board may also make or provide for such adjustments in the numbers of Common
Shares specified in Sections 3(a)(ii), 3(a)(iii), 3(b), and 3(c) of this Plan as
the Board may in good faith determine to be appropriate in order to reflect any
transaction or event described in this Section 12.

        13.     Fractional Shares. The Corporation shall not be required to
issue any fractional Common Shares pursuant to this Plan. The Board may provide
for the elimination of fractions or for the settlement thereof in cash.

        14.     Withholding Taxes. To the extent that the Corporation is
required to withhold federal, state, local or foreign taxes in connection with
any payment made or benefit realized by a Participant or other person under this
Plan, and the amounts available to the Corporation for the withholding are
insufficient, it shall be a condition to the receipt of any such payment or the
realization of any such benefit that the Participant or such other person make
arrangements satisfactory to the Corporation for payment of the balance of any
taxes required to be withheld. At the discretion of the Board (to the extent
permitted under any agreements, including without limitation indentures or other
financing agreements, to which the Corporation may be a party), any such
arrangements may include relinquishment of a portion of any such payment or
benefit. In no event, however, shall the Corporation accept Common Shares for
payment of taxes in excess of required tax withholding rates, except that, in
the discretion of the Board (to the extent permitted under any agreements,
including without limitation indentures or other financing agreements, to which
the Corporation may be a party), a Participant may surrender Common Shares held
for more than six months to satisfy any tax obligation resulting from any such
transaction.

        15.     Certain Terminations of Employment, Hardship and Approved Leaves
of Absence. Notwithstanding any other provision of this Plan to the contrary, in
the event of termination of employment by reason of death, disability, normal
retirement, early retirement with the consent of the Corporation, termination of
employment to enter public service with the consent of the Corporation or leave
of absence approved by the Corporation, or in the event of hardship or other
special circumstances, of a Participant who holds an Option Right or
Appreciation Right that is not immediately and fully exercisable, any Restricted
Shares as to which the substantial risk of forfeiture or the prohibition or
restriction on transfer has not lapsed, any Deferred Shares as to which the
Deferral Period is not complete, any Performance Shares or Performance Units
that have not been fully earned, or any Common Shares that are subject to any
transfer restriction pursuant to Section 11(c) of this Plan, the Board may take
any action that it deems to be equitable under the circumstances or in the best
interests of the Corporation, including but not limited to waiving or modifying
any limitation or requirement with respect to any award under this Plan.

                                       17

<PAGE>   18

        16.     Foreign Participants. In order to facilitate the making of any
award or combination of awards under this Plan, the Board may provide for such
special terms for awards to Participants who are foreign nationals, or who are
employed by or engaged as consultants to the Corporation, any Subsidiary or any
Designated Affiliate outside of the United States of America, as the Board may
consider necessary or appropriate to accommodate differences in local law, tax
policy or custom. In addition, the Board may approve such supplements to, or
amendments, restatements or alternative versions of, this Plan as it may
consider necessary or appropriate for such purposes without thereby affecting
the terms of this Plan as in effect for any other purpose; provided, however,
that no such supplements, amendments, restatements or alternative versions shall
include any provisions that are inconsistent with the terms of this Plan, as
then in effect, unless this Plan could have been amended to eliminate the
inconsistency without further approval by the stockholders of the Corporation.

        17.     Administration of the Plan.

        (a)     This Plan shall be administered by the Board, which may from
time to time delegate all or any part of its authority under this Plan to a
committee of the Board consisting of two or more members of the Board, or a
subcommittee of a committee of the Board consisting exclusively of two or more
"Non-Employee Directors" (as defined in Rule 16b-3), appointed by the Board. A
majority of the committee (or subcommittee) shall constitute a quorum, and the
action of the members of the committee (or subcommittee) present at any meeting
at which a quorum is present, or acts unanimously approved in writing, shall be
the acts of the committee (or subcommittee). To the extent of any such
delegation, references in this Plan to the Board shall be deemed to be
references to any such committee or subcommittee.

        (b)     The Board may from time to time reserve a specified number of
Common Shares, subject to adjustment as provided in Section 12 of this Plan, for
grants of Nonqualified Options to Participants who have agreed to commence
employment with the Corporation or any Subsidiary and may delegate to one or
more officers of the Corporation the authority to determine the Participants to
whom such Nonqualified Options shall be granted, and to determine the number of
such Common Shares to which any such Nonqualified Option shall pertain, subject
to the terms and conditions of this Plan and the terms and conditions of an
agreement evidencing any such Nonqualified Option and approved by resolution of
the Board at the time of such delegation. For the purposes of Section 4(b) of
this Plan, as it relates to any Nonqualified Option that shall be granted
pursuant to this Section 17(b), (i) the Date of Grant shall be the date on which
the Participant agrees to accept employment with the Corporation or any
Subsidiary, which may precede the date on which the Participant's employment
actually commences (or, if such date is not specified in the Participant's
employment offer and acceptance materials, the Date of Grant will be the
commencement date of such Participant's employment with the Corporation or any
Subsidiary), and (ii) the Market Value per Share on the Date of Grant shall be
the closing price of the Class A Common Shares on the Nasdaq Stock Market on the
last trading day immediately preceding the Date of Grant.

        (c)     The interpretation and construction by the Board of any
provision of this Plan or any agreement, notification or document evidencing the
grant of Option Rights, Appreciation Rights, Restricted Shares, Deferred Shares,
Performance Shares or Performance Units, and any determination by the Board
pursuant to any provision of this Plan or any such agreement,

notification or document, shall be final and conclusive. No member of the Board
shall be liable for any such action taken or determination made in good faith.

        18.     Amendments and Other Matters.

        (a)     The Board may at any time and from time to time amend this Plan
in whole or in part; provided, however, that (1) any amendment that must be
approved by the stockholders of the Corporation in order to comply with
applicable law or the rules of any national securities exchange or automated
quotation system upon which the Class A Common Shares are traded or quoted shall
not be effective unless and until such approval has been obtained and (2) the
provisions of Sections 4(g), 7(c) and 8(b), including but not limited to clause
(ii) of each of these Sections, may not be amended following a Change of Control
in any way that would adversely affect the rights of holders of awards granted
under Sections 4, 7 and 8 hereof.

        (b)     With the concurrence of the affected Participant, the Board may
cancel any agreement evidencing Option Rights or any other award granted under
this Plan. In the event of any such cancellation, the Board may authorize the
granting of new Option Rights or other awards hereunder, which may or may not
cover the same number of Common Shares as had been covered by the canceled
Option Rights or other award, at such Option Price, in such manner and subject
to such other terms, conditions and discretion as would have been permitted
under this Plan had the canceled Option Rights or other award not been granted.

        (c)     The Board may grant under this Plan any award or combination of
awards authorized under this Plan, including but not limited to Replacement
Option Rights, in exchange for the surrender and cancellation of an award that
was not granted under this Plan (including but not limited to an award that was
granted by the Corporation or a Subsidiary, or by another corporation that is
acquired by the Corporation or a Subsidiary by merger or otherwise, prior to the
adoption of this Plan by the Board), and any such award or combination of awards
so granted under this Plan may or may not cover the same number of Common Shares
as had been covered by the canceled award and shall be subject to such other
terms, conditions and discretion as would have been permitted under this Plan
had the canceled award not been granted.

        (d)     This Plan shall not confer upon any Participant any right with
respect to continuance of employment or other service with the Corporation, any
Subsidiary or Designated Affiliate and shall not interfere in any way with any
right that the Corporation, any Subsidiary or Designated Affiliate would
otherwise have to terminate any Participant's employment or other service at
anytime.

        (e)     To the extent that any provision of this Plan would prevent any
Option Right that was intended to qualify as a Tax-Qualified Option from so
qualifying, any such provision shall be null and void with respect to any such
Option Right; provided, however, that any such provision shall remain in effect
with respect to other Option Rights, and there shall be no further effect on any
provision of this Plan.

        (f)     The Board may also permit Participants to elect to defer the
issuance of Common Shares or the settlement of awards in cash under this Plan
pursuant to such procedures, programs or rules as the Board may establish for
the purposes of this Plan. The Board may also provide

                                       19

that deferred issuances and settlements include the payment or crediting of
dividend equivalents or interest on the deferral amounts.

        (g)     The Board may condition the grant of any award or combination of
awards authorized under this Plan on the surrender or deferral by the
Participant of his or her right to receive a cash bonus or other compensation
otherwise payable by the Corporation or a Subsidiary to the Participant.

        (h)     All grants, exercises and sales of securities of the Corporation
made pursuant to this Plan must be made in compliance with (and may be modified
without the consent of the grantee to assure compliance with) all applicable
foreign, federal and state laws.
