(i) Delegation With Respect to Awards. Subject to the terms of the Plan, the
Committee’s charter and Applicable Law, the Committee may, but need not,
delegate from time to time some or all of its authority under the Plan to a
committee consisting of one or more members of the Committee to (a) grant
Awards, (b) to cancel, modify or waive rights with respect to Awards, or (c) to
alter, discontinue, suspend or terminate Awards held by Participants; provided,
however, that the Committee may not delegate its authority to take any action
with respect to any Awards held by, or to be granted to, any individual (1) who
is subject on the date of the grant to the reporting rules under Section 16(a)
of the Exchange Act or (2) who is a Section 162(m) Participant. Any delegation
hereunder shall be subject to the restrictions and limits that the Committee
specifies at the time of such delegation of authority and may be rescinded at
any time by the Committee. At all times, any committee appointed under this
Section 5.2 shall serve in such capacity at the pleasure of the Committee.

(ii) Delegation of Ministerial Functions. The Committee may delegate
ministerial, non-discretionary functions to individuals who are officers or

Committee’s decision or action was arbitrary or capricious or was unlawful.

any action under this Plan, the Board or a committee, as the case may be, may

Company or any of its Subsidiaries shall be liable for any such action or
determination taken or made or omitted in good faith.

determination made in good faith with respect to the Plan, any Award granted or
any Award Agreement entered into hereunder.

Individual who has been granted an award, if otherwise eligible, may be granted
additional awards if the Committee shall so determine.

7

--------------------------------------------------------------------------------

 

7. Options.

7.1 Types of Options. Each Option granted under the Plan may be designated by
the Committee, in its sole discretion, either as (i) an Incentive Stock Option
or (ii) as a Non-qualified Stock Option. Options designated as Incentive Stock
Options that fail to continue to meet the requirements of Section 422 of the
Code shall be redesignated as Non-qualified Stock Options automatically on the
date of such failure to continue to meet such requirements without further
action by the Committee. In the absence of any designation, Options granted
under the Plan will be deemed to be Incentive Stock Options to the extent that
such Options meet the requirements of Section 422 of the Code.

7.2 Grant of Options. Subject to the terms and conditions of the Plan, the
Committee may, at any time and from time to time, prior to the date of
termination of the Plan, grant to such Eligible Individuals as the Committee may
determine, Options to purchase such number of shares of Class A Common Stock on
such terms and conditions as the Committee may determine. The date on which the
Committee approves the grant of an Option (or such later date as is specified by
the Committee) shall be considered the Grant Date. All Options granted pursuant
to the Plan shall be evidenced by an Award Agreement in such form or forms as
the Committee shall determine. Award Agreements may contain different
provisions, provided, however, that all such Award Agreements shall comply with
all terms of the Plan. 

7.3 Limitation on Incentive Stock Options.  

(i) Section 424 Employees. Incentive Stock Options may only be granted to
Section 424 Employees. Subject to the terms and conditions of this Plan and the
Award Agreement (including all vesting provisions and option periods), any and
all Incentive Stock Options which an employee fails to exercise within ninety
(90) days after the date said employee ceases to be a Section 424 Employee shall
automatically be classified as Non-qualified Stock Options to the extent that
said Options have not otherwise been terminated.

(ii) Ten Percent Shareholder. Notwithstanding any other provision of this Plan
to the contrary, no individual may receive an Incentive Stock Option under the
Plan if such individual, at the time the award is granted, owns (after
application of the rules contained in Section 424(d) of the Code) stock
possessing more than ten percent (10%) of the total combined voting power of all
classes of stock of the Company, unless (a) the exercise price for each share of
Class A Common Stock subject to such Incentive Stock Option is at least one
hundred ten percent (110%) of the Fair Market Value of a share of Class A Common
Stock on the date of grant and (b) such Incentive Stock Option is not
exercisable after the fifth (5th) anniversary of the date of grant.

(iii) Limitation on Grants. The aggregate Fair Market Value (determined with
respect to each Incentive Stock Option at the time such Incentive Stock Option
is granted) of the shares of Class A Common Stock with respect to which
Incentive Stock Options are exercisable for the first time by an individual
during any calendar year (under this Plan or any other plan of the Company)
shall not exceed $100,000. If an Incentive Stock Option is granted pursuant to
which the aggregate Fair Market Value of shares with respect to which it first
becomes exercisable in any calendar year by an individual exceeds such $100,000
limitation, the portion of such Option which is in excess of the $100,000
limitation, and any Options issued subsequently in the same calendar year, shall
be treated as a Non-qualified Stock Option pursuant to Section 422(d)(1) of the
Code. In the event that an individual is eligible to participate in any other
stock option plan of the Company which is also intended to comply with the
provisions of Section 422 of the Code, such $100,000 limitation shall apply to
the aggregate number of shares for which Incentive Stock Options may be granted
under this Plan and all such other plans.

(iv) Other Terms. Award Agreements evidencing Incentive Stock Options shall
contain such other terms and conditions as may be necessary to qualify, to the
extent determined desirable by the Committee, with the applicable provisions of
Section 422 of the Code.

8

--------------------------------------------------------------------------------

 

7.4 Exercise Price. The per share exercise price for the Shares to be issued
pursuant to exercise of an Option shall be determined by the Committee, subject
to the following:

(i) The per Share exercise price of an Option shall be no less than 100% of the
Fair Market Value per Share on the Grant Date.

(ii) Notwithstanding the foregoing, at the Committee’s discretion, Options may
be granted in substitution and/or conversion of options or stock appreciation
rights of an acquired entity, with a per Share exercise price of less than 100%
of the Fair Market Value per Share on the date of such substitution and/or
conversion if such exercise price is based on a formula set forth in the terms
of such options/stock appreciation rights or in the terms of the agreement
providing for such acquisition.

7.5 Option Period. Subject to the provisions of Sections 7.3 and 14.2, each
Option granted pursuant to Section 7 under the Plan shall terminate and all
rights to purchase shares thereunder shall cease on the tenth (10th) anniversary
of the date such Option is granted, or on such date prior thereto as may be
fixed by the Committee and stated in the Award Agreement relating to such
Option. Notwithstanding the foregoing, the Committee may in its discretion, at
any time prior to the expiration or termination of any Option, extend the term
of any such Option for such additional period as the Committee in its discretion
may determine; provided, however, that in no event shall the aggregate option
period with respect to any Option, including the initial term of such Option and
any extensions thereof, exceed ten (10) years.

7.6 Vesting. Each Award Agreement will specify the vesting schedule applicable
to the Option granted thereunder. Notwithstanding the foregoing, the Committee
may in its discretion provide that any vesting requirement or other such
limitation on the exercise of an Option may be rescinded, modified or waived by
the Committee, in its sole discretion, at any time and from time to time after
the date of grant of such Option, so as to accelerate the time at which the
Option may be exercised.

7.7 Exercise of Option.  

(i) Procedure for Exercise.

the Plan and at such times and under such conditions as determined by the
Committee and set forth in the respective Award Agreement. Unless the Committee
provides otherwise: (1) no Option may be exercised during any leave of absence
other than an approved personal or medical leave with an employment guarantee
upon return; and (2) an Option shall continue to vest during any authorized
leave of absence and such Option may be exercised to the extent vested and
exercisable upon the Participant’s return to active employment status.

(b) An Option shall be deemed exercised when the Company, or its agent appointed

agent of the Company), no right to vote or receive dividends or any other rights
as a shareholder shall exist with respect to the Shares subject to an Option,
notwithstanding the exercise of the Option.

9

--------------------------------------------------------------------------------

 

7.8 Form of Consideration. Unless provided otherwise in the Award Agreement, the
following shall be deemed to be acceptable forms of consideration for exercising
an Option:

(i) cash;

(ii) check or wire transfer (denominated in U.S. Dollars);

(iii) subject to any conditions or limitations established by the Committee in
the applicable Award Agreement, other Shares which have a Fair Market Value on
the date of surrender equal to the aggregate exercise price of the Shares as to
which said Option shall be exercised;

(iv) subject to any conditions or limitations established by the Committee in
the applicable Award Agreement, withholding of Shares deliverable upon exercise,
which have a Fair Market Value on the date of surrender equal to the aggregate
exercise price of the Shares as to which said Option shall be exercised;

(v) consideration received by the Company under a broker-assisted sale and
remittance program, or “cashless” exercise/sale procedure;

(vi) such other consideration and method of payment for the issuance of Shares
to the extent permitted by Applicable Laws; or

(vii) any combination of the foregoing methods of payment.

7.9 Transferability. No Incentive Stock Option shall be assignable or
transferable by the Participant to whom it is granted, other than by will or the
laws of descent and distribution. No Non-qualified Stock Option shall be
assignable or transferable by the Participant to whom it is granted, other than
by will or the laws of descent and distribution; provided, however, that
Non-qualified Stock Options may be transferred or assigned to (i) family members
or entities (including trusts) established for the benefit of the Participant or
the Participant’s family members or (ii) any other person, as permitted by
applicable securities law. Any Option assigned or transferred pursuant to this
Section 7.9 shall continue to be subject to the same terms and conditions as
were applicable to the Option immediately before the transfer; provided,
however, than any Option transferred for value may not be exercised under any
Registration Statement on Form S-8 and upon exercise of such transferred Option
the holder would only be entitled to receive shares of restricted stock that
have not been registered under the Securities Act of 1933.

8. Restricted Stock Award.

8.1 Grant of a Restricted Stock Award. Subject to the provisions of the Plan,
the Committee may grant a Restricted Stock Award. Each grant of a Restricted
Stock Award shall be evidenced by an Award Agreement in such form as the
Committee shall from time to time approve.

8.2 Issue Date and Vesting Date. At the time of the grant of a Restricted Stock
Award, the Committee shall establish an Issue Date(s) and a Vesting Date(s) with
respect to such Restricted Stock Award. The Committee may divide a Restricted
Stock Award into classes and assign a different Issue Date and/or Vesting Date
for each class. Upon an Issue Date with respect to a share of a Restricted Stock
Award, a share of a Restricted Stock Award shall be issued in accordance with
the provisions of Section 8.4. Provided that all conditions to the vesting of a
share of a Restricted Stock Award imposed pursuant to Section 8.3 are satisfied,
upon the occurrence of the Vesting Date with respect to a share of Restricted
Stock, such share of Restricted Stock shall vest.

8.3 Vesting. At the time of the grant of a Restricted Stock Award, the Committee
may impose such restrictions or conditions, not inconsistent with the provisions
hereof, to the vesting of such Restricted Stock as it, in its absolute
discretion, deems appropriate. By way of example and not by way of limitation,
the Committee may require, as a condition to the vesting of any class or classes
of shares underlying a Restricted Stock Award, that the Participant or the
Company achieve certain performance criteria, the

10

--------------------------------------------------------------------------------

 

Class A Common Stock attain certain stock price or prices, or such other
criteria to be specified by the Committee at the time of the grant of such
Shares in the applicable Award Agreement.

8.4 Issuance of Certificates.  

(i) Reasonably promptly after the Issue Date with respect to a Restricted Stock
Award, the Company shall cause to be issued and delivered, either physically or
electronically shares of Class A Common Stock, registered in the name of the
Participant to whom such shares were granted; provided, that the Company shall
not cause a physical stock certificate to be issued unless it has received a
stock power duly endorsed in blank with respect to such shares. Each stock
certificate representing unvested shares of Restricted Stock shall bear the
following legend:

“THE TRANSFERABILITY OF THIS CERTIFICATE AND THE SHARES OF STOCK REPRESENTED
HEREBY IS SUBJECT TO THE RESTRICTIONS, TERMS AND CONDITIONS (INCLUDING
FORFEITURE AND RESTRICTIONS AGAINST TRANSFER) CONTAINED IN THE SBA
COMMUNICATIONS CORPORATION 2010 PERFORMANCE AND EQUITY INCENTIVE PLAN AND AN
AWARD AGREEMENT ENTERED INTO BETWEEN THE REGISTERED OWNER OF SUCH SHARES AND SBA
COMMUNICATIONS CORPORATION. A COPY OF THE PLAN AND AGREEMENT IS ON FILE IN THE
OFFICE OF THE SECRETARY OF SBA COMMUNICATIONS CORPORATION. SUCH LEGEND SHALL NOT
BE REMOVED FROM THE CERTIFICATE EVIDENCING SUCH SHARES UNTIL SUCH SHARES VEST
PURSUANT TO THE TERMS HEREOF.”

(ii) To the extent that the shares of Restricted Stock are delivered
electronically, the Company may make such provisions as it deems necessary to
ensure that each share of Restricted Stock is subject to the same terms and
conditions as shares that are represented by a physical stock certificate. Each
certificate issued pursuant to Section 8.4(i) hereof, together with the stock
powers relating to the shares of Restricted Stock evidenced by such certificate,
shall be deposited by the Company with a custodian designated by the Company.
The Company shall cause such custodian to issue to the Participant a receipt
evidencing the certificates held by it which are registered in the name of the
Participant.

8.5 Dividends and Splits. As a condition to the grant of an award of a
Restricted Stock Award, the Committee may require or permit a Participant to
elect that any cash dividends paid on a share of a Restricted Stock Award be
automatically reinvested in additional shares of Restricted Stock or applied to
the purchase of additional awards under this Plan. Unless otherwise determined
by the Committee, stock distributed in connection with a stock split or stock
dividend, and other property distributed as a dividend, shall be subject to
restrictions and a risk of forfeiture to the same extent as the Restricted Stock
Award with respect to which such stock or other property has been distributed.

8.6 Consequences Upon Vesting. Upon the vesting of a share of a Restricted Stock
Award pursuant to the terms hereof, the vesting restrictions shall cease to
apply to such share. Reasonably promptly after a share of a Restricted Stock
Award vests pursuant to the terms hereof, the Company shall cause to be issued
and delivered to the Participant to whom such shares were granted, a either
(i) a certificate evidencing such shares of Class A Common Stock or (ii) an
electronic issuance evidencing such shares of Class A Common Stock, together
with any other property of the Participant held by the custodian pursuant to
Section 8.4 hereof; provided, however, that to the extent that the Participant
is then subject to Stock Ownership Guidelines and that such shares are subject
to transfer restrictions pursuant to such Stock Ownership Guidelines then such
shares (i) shall be issued with a legend indicating that “THE TRANSFERABILITY OF
THIS CERTIFICATE AND THE SHARES OF STOCK REPRESENTED HEREBY IS SUBJECT TO
TRANSFERABILITY RESTRICTIONS CONTAINED IN THE SBA COMMUNICATIONS CORPORATION
STOCK OWNERSHIP GUIDELINES” or (ii) if delivered electronically, the Company may
make such provisions as it deems necessary to ensure that each share of Class A
Common Stock is subject to the same terms and conditions as shares that are
represented by a physical stock certificate.

11

--------------------------------------------------------------------------------

 

9. Restricted Stock Units.

9.1 Grant of Restricted Stock Units. Subject to the terms of the Plan, the
Committee may grant awards of Restricted Stock Units or RSUs. An award of RSUs
may be subject to the attainment of specified performance goals or targets,
forfeitability provisions and such other terms and conditions as the Committee
may determine, subject to the provisions of this Plan. At the time an award of
RSUs is made, the Committee shall establish a period of time during which the
RSUs shall vest. Each grant of a RSU shall be evidenced by an Award Agreement in
such form as the Committee shall from time to time approve.

9.2 Dividend Equivalent Accounts. If (and only if) required by the applicable
Award Agreement, prior to the expiration of the applicable vesting period of an
RSU, the Company shall pay dividend equivalent rights with respect to RSUs, in
which case, the Company shall establish an account for the Participant and
reflect in that account any securities, cash or other property comprising any
dividend or property distribution with respect to the Class A Common Stock
underlying each RSU. Each amount or other property credited to any such account
shall be subject to the same vesting conditions as the RSU to which it relates.
The Participant shall be paid the amounts or other property credited to such
account upon vesting of the RSU.

9.3 Rights as a Shareholder. Subject to the restrictions imposed under the terms
and conditions of this Plan and the applicable Award Agreement, each Participant
receiving RSUs shall have no rights as a shareholder with respect to such RSUs
until such time as Class A Common Stock are issued to the Participant. Except as
otherwise provided in the applicable Award Agreement, Class A Common Stock
issuable under an RSU shall be treated as issued on the first date that the
holder of the RSU is no longer subject to a substantial risk of forfeiture as
determined for purposes of Section 409A of the Code, and the holder shall be the
owner of such Class A Common Stock on such date.

9.4 Consequences Upon Vesting. Reasonably promptly after the vesting of an RSU,
the Company shall cause to be issued and delivered to the Participant to whom
such shares were granted, either (i) a certificate evidencing such shares of
Class A Common Stock or (ii) an electronic issuance evidencing such shares of
Class A Common Stock, together with any other property of the Participant held
by the custodian pursuant to Section 9.2 hereof; provided, however, that to the
extent that the Participant is then subject to Stock Ownership Guidelines and
that such shares are subject to transfer restrictions pursuant to such Stock
Ownership Guidelines then such shares (a) shall be issued with a legend
indicating that “THE TRANSFERABILITY OF THIS CERTIFICATE AND THE SHARES OF STOCK
REPRESENTED HEREBY IS SUBJECT TO TRANSFERABILITY RESTRICTIONS CONTAINED IN THE
SBA COMMUNICATIONS CORPORATION STOCK OWNERSHIP GUIDELINES” or (b) if delivered
electronically, the Company may make such provisions as it deems necessary to
ensure that each share of Class A Common Stock is subject to the same terms and
conditions as shares that are represented by a physical stock certificate.

10. Stock Appreciation Rights.

10.1 Grant of Stock Appreciation Rights. Subject to the terms of the Plan, any
Option granted under the Plan may include a SAR, either at the time of grant or
by amendment except that in the case of an Incentive Stock Option, such SAR
shall be granted only at the time of grant of the related Option. The Committee
may also award to Participants SARs independent of any Option. A SAR shall be
subject to such terms and conditions not inconsistent with the Plan as the
Committee shall impose. Each grant of a SAR shall be evidenced by an Award
Agreement in such form as the Committee shall from time to time approve.

10.2 Vesting. A SAR granted in connection with an Option shall become
exercisable, be transferable and shall lapse according to the same vesting
schedule, transferability and lapse rules that are established by

12

--------------------------------------------------------------------------------

 

the Committee for the Option. A SAR granted independent of an Option shall
become exercisable, be transferable and shall lapse in accordance with a vesting
schedule, transferability and lapse rules established by the Committee.
Notwithstanding the above, a SAR shall not be exercisable by a person subject to
Section 16(b) of the Exchange Act for at least six (6) months following the date
the SAR is granted.

10.3 Failure to Exercise. If on the last day of the Option period (or in the
case of a SAR independent of an Option, the SAR period established by the
Committee), the Fair Market Value of the stock exceeds the exercise price, the
Participant has not exercised the Option or SAR, and neither the Option nor the
SAR has lapsed, such SAR shall be deemed to have been exercised by the
Participant on such last day and the Company shall make the appropriate payment
therefor.

10.4 Payment. The amount of additional compensation which may be received
pursuant to the award of one SAR is the excess, if any, of the Fair Market Value
of one share of Class A Common Stock on the Appreciation Date over the exercise
price, in the case of a SAR granted in connection with an Option, or the Fair
Market Value of one (1) share of Class A Common Stock on the date the SAR is
granted, in the case of a SAR granted independent of an Option. The Company
shall pay such excess in cash, in shares of Class A Common Stock valued at Fair
Market Value, or any combination thereof, as determined by the Committee.
Fractional shares shall be settled in cash.

10.5 Designation of Appreciation Date. A Participant may designate an
Appreciation Date at such time or times as may be determined by the Committee at
the time of grant by filing an irrevocable written notice with the Committee or
its designee, specifying the number of SARs to which the Appreciation Date
relates, and the date on which such SARs were awarded. Such time or times
determined by the Committee may take into account any applicable “window
periods” required by Rule 16b-3 under the Exchange Act.

10.6 Expiration. Except as otherwise provided in the case of SARs granted in
connection with Options, the SARs shall expire on a date designated by the
Committee which is not later than ten (10) years after the date on which the SAR
was awarded.

11. Stock Bonuses. Subject to the provisions of the Plan, the Committee may
grant Stock Bonuses in such amounts as it shall determine from time to time. A
Stock Bonus shall be paid at such time and subject to such conditions as the
Committee shall determine at the time of the grant of such Stock Bonus. Shares
of Class A Common Stock granted as a Stock Bonus shall be issued in certificated
form or electronically and delivered to such Participant as soon as practicable
after the date on which such Stock Bonus is required to be paid.

12. Performance Awards

12.1 Grant of Performance Awards. Subject to the terms of the Plan, the
Committee may grant Performance Awards to any officer or employee of the Company
or its Subsidiaries. The provisions of Performance Awards need not be the same
with respect to all Participants. A Performance Award may consist of a right
that is (i) denominated in cash or Shares (including but not limited to
Restricted Stock or Restricted Stock Units), (ii) valued, as determined by the
Committee, in accordance with the achievement of one or more performance
criteria as the Committee shall establish, and (iii) payable at such time and in
such form as the Committee shall determine. Each grant of a Performance Award
shall be evidenced by an Award Agreement in such form as the Committee shall
from time to time approve.

12.2 Terms and Conditions.  

(i) Each Performance Award shall contain provisions regarding (a) the target and
maximum amount payable to the Participant, (b) the performance criteria and
level of achievement versus these criteria

13

--------------------------------------------------------------------------------

 

which shall determine the amount of such payment, (c) the period as to which
performance shall be measured for establishing the amount of any payment,
(d) the timing of any payment earned by virtue of performance, (e) restrictions
on the alienation or transfer of the Performance Award prior to actual payment,
(f) forfeiture provisions, and (g) such further terms and conditions, in each
case not inconsistent with the Plan, as may be determined from time to time by
the Committee. In the event the Committee provides for dividends or dividend
equivalents to be payable with respect to any Performance Awards denominated in
Shares, actual payment of such dividends or dividend equivalents shall be
conditioned upon the performance goals underlying the Performance Award being
met.

(ii) The maximum amount payable under a Performance Award that is settled for
cash may be a multiple of the target amount payable. However, the maximum number
of shares subject to any Performance Award denominated in Shares granted in any
fiscal year to a Participant shall be 500,000, subject to adjustment as provided
in Section 16.1, and the maximum amount paid in respect of a Performance Award
denominated in cash or value other than Shares on an annualized fiscal year
basis with respect to any Participant shall be $2,500,000.

(iii) The Committee shall have the power to impose such other restrictions on
Awards subject to this Section 12.2 as it may deem necessary or appropriate to
ensure that such Awards satisfy all requirements for “performance-based
compensation” within the meaning of Section 162(m)(4)(C) of the Code, or any
successor provision thereto. Notwithstanding any provision of the Plan to the
contrary, the Committee shall not be authorized to increase the amount payable
under any Award to which this Section 12 applies upon attainment of such
pre-established formula.

12.3 Performance Criteria. The Committee shall establish the performance
criteria and level of achievement versus these criteria which shall determine
the target and the minimum and maximum amount payable under a Performance Award,
which criteria may be based on financial performance and/or personal performance
evaluations. The Committee may specify the percentage of the target Performance
Award that is intended to satisfy the requirements for “performance-based
compensation” under Section 162(m) of the Code. Notwithstanding anything to the
contrary herein, the performance criteria for any portion of a Performance Award
that is intended to satisfy the requirements for “performance-based
compensation” under Section 162(m) of the Code shall be a measure established by
the Committee based on one or more Qualifying Performance Criteria selected by
the Committee and specified in writing not later than ninety (90) days after the
commencement of the performance period to which the performance goals relate
(and, in the case of performance periods of less than one year, in no event
after 25% or more of the performance period has elapsed) and while performance
relating to such target(s) remains substantially uncertain within the meaning of
Section 162(m) of the Code. The applicable performance measurement period may
not be less than three (3) months nor more than ten (10) years.

12.4 Qualifying Performance Criteria. For purposes of this Plan, the term
“Qualifying Performance Criteria” shall mean any one or more of the following
performance criteria, either individually, alternatively or in any combination,
applied to either the Company as a whole or to a business unit, Affiliate or
business segment, either individually, alternatively or in any combination, and
measured either annually or cumulatively over a period of years, on an absolute
basis or a per share basis or relative to a pre-established target, to previous
years’ results or to a designated comparison group, in each case as specified by
the Committee in the Award: (i) cash flow, tower cash flow or equity free cash
flow; (ii) earnings (including gross margin, EBITDA (earnings before interest,
taxes, depreciation and amortization)); (iii) earnings per share; (iv) growth in
earnings, cash flow, revenue, gross margin, operating expense or operating
expense as a percentage of revenue; (v) stock price; (vi) return on equity or
average shareholder equity; (vii) total shareholder return; (viii) return on
capital; (ix) return on assets or net assets; (x) return on investment;
(xi) revenue; (xii) income or net income; (xiii) operating income or net
operating income; (xiv) operating profit, net operating profit or controllable
operating profit; (xv) operating margin or operating expense or operating
expense as a percentage of revenue; (xvi) return

14

--------------------------------------------------------------------------------

 

on operating revenue; (xvii) market share or customer indicators;
(xviii) contract awards or backlog; (xix) overhead or other expense reduction;
(xx) growth in shareholder value relative to the moving average of the S&P 500
Index or a peer group index; (xxi) credit rating; (xxii) strategic plan
development and implementation (xxiii) succession plan development and
implementation; (xxiv) acquisitions consummated; (xxv) improvement in
productivity or workforce diversity; (xxvi) attainment of objective operating
goals and employee metrics; (xxvii) economic value added; and (xxviii) any other
similar criteria. These terms are used as applied under generally accepted
accounting principles or in the financial reporting of the Company or of its
Subsidiaries. To the extent consistent with Section 162(m) of the Code, the
Committee may appropriately adjust any evaluation of performance under a
Qualifying Performance Criteria to mitigate the unbudgeted impact of material,
unusual or nonrecurring gains and losses, accounting changes or other
extraordinary events not foreseen at the time the targets were set unless the
Committee provides otherwise at the time of establishing the targets; provided
that the Committee may not make any adjustment to the extent it would adversely
affect the qualification of any compensation payable under such performance
targets as “performance-based compensation” under Section 162(m).

12.5 Timing and Form of Payment. The Committee shall determine the timing of
payment of any Performance Award. The Committee may provide for or, subject to
such terms and conditions as the Committee may specify, may permit a Participant
to elect (in a manner consistent with Section 409A of the Code) for the payment
of any Performance Award to be deferred to a specified date or event.

13. Other Stock-Based Awards

Awards of shares of Class A Common Stock, stock appreciation rights, phantom
stock and other awards that are valued in whole or in part by reference to, or
otherwise based on, Class A Common Stock, may also be made, from time to time,
to Eligible Individuals as may be selected by the Committee. Such awards may be
made alone or in addition to or in connection with any Option, Restricted Stock
Unit or any other award granted hereunder. The Committee may determine the terms
and conditions of any such award. Each award shall be evidenced by an Award
Agreement that shall specify the number of shares of Class A Common Stock
subject to the award, any consideration therefor, any vesting or performance
requirements and such other terms and conditions as the Committee shall
determine.

14. Effect of Termination of Service on Awards.

14.1 Termination of Employment. The Committee shall establish the effect of a
termination of employment or service on the rights and benefits under each award
under this Plan and in so doing may make distinctions based upon, inter alia,
the cause of termination and type of award. If the Participant is not an
employee of the Company or one of its Subsidiaries and provides other services
to the Company or one of its Subsidiaries, the Committee shall be the sole judge
for purposes of this Plan (unless a contract or the Award Agreement otherwise
provides) of whether the Participant continues to render services to the Company
or one of its Subsidiaries and the date, if any, upon which such services shall
be deemed to have terminated.

14.2 Termination of Employment Without Cause. Unless otherwise provided in an
Award Agreement, upon the termination of the employment or other service of a
Participant with the Company, a Subsidiary or Affiliate, other than by reason of
Cause, death or Disability, any Option, RSU or SAR granted to such Participant
which has vested as of the date upon which the termination occurs shall be
exercisable for a period not to exceed ninety (90) days after such termination.
Upon such termination, (i) the Participant’s unvested Options or SARs shall
expire and the Participant shall have no further right to exercises such Options
or SARs and (ii) any Restricted Stock or RSU that is subject to restrictions at
the time of termination shall be forfeited and reacquired by the Company.
Notwithstanding the provisions of this Section 14.2, the Committee may provide,
by rule or regulation, in any Award Agreement, or in any individual case, in its
sole discretion, that following the termination of employment or service of a
Participant with the Company, a Subsidiary or Affiliate, other than a
termination resulting from Cause, a

15

--------------------------------------------------------------------------------

 

Participant may (a) exercise an Option, in whole or in part, at any time
subsequent to such termination of employment or service and prior to termination
of the Option pursuant to Section 7.6 above, either subject to or without regard
to any vesting or other limitation on exercise imposed pursuant to the
applicable Award Agreement and (b) any restrictions or forfeiture conditions
relating to the vesting of a Restricted Stock Award or Restricted Stock Unit
shall be waived in whole or in part in the event of such termination.

14.3 Termination of Employment for Cause. Upon termination of the employment or
other service of a Participant with the Company, a Subsidiary or Affiliate, as
the case may be, for Cause, (i) any Option or SAR granted to the Participant
shall expire immediately and the Participant shall have no further right to
exercise such Option or SAR, as the case may be and (ii) any Restricted Stock or
RSU that is subject to restrictions at the time of termination shall be
forfeited and reacquired by the Company. The Committee shall determine whether
Cause exists for purposes of this Plan.

14.4 Termination of Employment by Disability or Death. Unless otherwise provided
in an Award Agreement, if a Participant’s employment or service with the
Company, the Subsidiary or Affiliate, as the case may be, terminates by reason
of Disability or death, all outstanding Options and SARs held by the Participant
at the time of death or Disability (the “Date of Termination by Death or
Disability”) shall immediately vest and, (i) in the case of termination by
Disability, the Participant, or (ii) in the case of termination by death, the
Participant’s estate, the devisee named in the Participant’s valid last will and
testament or the Participant’s heir at law who inherits the Option (whichever is
applicable), has the right, at any time prior to the one year anniversary of the
Date of Termination by Death or Disability to exercise, in whole or in part, any
portion of the Options or SARs held by the Participant on the Date of
Termination by Death or Disability. Unless otherwise provided in a Award
Agreement, if a Participant’s employment or service with the Company, the
Subsidiary or Affiliate, as the case may be, terminates by reason of Disability
or death, any time-based restrictions applicable to any outstanding RSU or
Restricted Stock shall be deemed waived. To the extent that any RSU or
Restricted Stock is subject to forfeiture based upon the achievement of
performance requirements, the Committee shall, (a) determine the extent to which
such performance requirements have been met as of the Date of Termination by
Death or Disability based upon such audited or unaudited financial information
then available or other information as it deems relevant, and (b) cause to be
paid to each Participant partial or full Awards with respect to such RSU or
Restricted Stock based upon the Committee’s determination of the degree of
attainment of the applicable performance requirements.

14.5 Events Not Deemed Terminations of Service. Unless the express policy of the
Company or one of its Subsidiaries or Affiliates, as the case may be, or the
Committee, otherwise provides, the employment relationship shall not be
considered terminated in the case of (i) sick leave, (ii) military leave, or
(iii) any other leave of absence authorized by the Company or one of its
Subsidiaries, or the Committee; provided that unless reemployment upon the
expiration of such leave is guaranteed by contract or law, such leave is for a
period of not more than three (3) months. In the case of any employee of the
Company or one of its Subsidiaries on an approved leave of absence, continued
vesting of the award while on leave from the employ of the Company or one of its
Subsidiaries may be suspended until the employee returns to service, unless the
Committee otherwise provides or Applicable Laws otherwise require. In no event
shall an award be exercised after the expiration of the term set forth in the
Award Agreement.

14.6 Effect of Change of Entity Status. Unless otherwise provided in an Award
Agreement or by the Committee, in its sole and absolute discretion, on a case-by
case basis, for purposes of this Plan and any Award, if an entity ceases to be a
Subsidiary or Affiliate of the Company, a termination of employment or service
shall be deemed to have occurred with respect to each Eligible Individual in
respect of such Subsidiary or Affiliate who does not continue as an Eligible
Individual in respect of another entity within the Company or another Subsidiary
or Affiliate that continues as such after giving effect to the transaction or
other event giving rise to the change in status.

16

--------------------------------------------------------------------------------

 

15. Awards to Independent Directors

15.1 Initial Grants of Options to Independent Directors. Each person who is
initially elected to the Board after the Effective Date and who is an
Independent Director at the time of such initial election shall automatically be
granted Non-qualified Stock Options, Restricted Stock and/or Restricted Stock
Units with an aggregate value as established by the Board from time to time;
provided, however, that the number of shares of Class A Common Stock subject to
any Non-qualified Stock Option, Restricted Stock or RSU awarded under this

grant of Non-qualified Stock Options, Restricted Stock and/or RSUs to all

however, that no Option, Restricted Stock, and/or RSU shall be granted to an
Independent Director under this Section 15.2 during any year in which such
Independent Director received an Award pursuant to Section 15.1.

15.3 Additional Awards to Independent Directors. In addition to any other grants

SAR granted to an Independent Director shall equal 100% of the Fair Market Value
of a share of Class A Common Stock on the date the option is granted.

provisions of this Section 18, (i) any Option, SAR, Restricted Stock or RSU

time-based restrictions may have such restrictions waived upon the retirement of
the Independent Director in accordance with the Company’s retirement policy
applicable to directors.

15.6 . Vesting of Restricted Stock or Restricted Stock Units. Reasonably
promptly after the vesting of a Restricted Stock Award or a RSU, the Company
shall cause to be issued and delivered, either physically or electronically, to
the Independent Director to whom such shares were granted, either (i) a
certificate evidencing such shares of Class A Common Stock or (ii) an electronic
issuance evidencing such shares of Class A Common Stock; provided, however, that
to the extent that the Independent Director is then subject to Stock Ownership
Guidelines and that such shares are subject to transfer restrictions pursuant to
such Stock Ownership Guidelines then such shares (a) shall be issued with a
legend indicating that “THE TRANSFERABILITY OF THIS CERTIFICATE AND THE SHARES
OF STOCK REPRESENTED HEREBY IS SUBJECT TO THE RESTRICTIONS, TERMS AND CONDITIONS
(INCLUDING FORFEITURE AND RESTRICTIONS AGAINST TRANSFER) CONTAINED IN THE SBA

conditions as shares that are represented by a physical stock certificate.

17

--------------------------------------------------------------------------------

 

15.7 Term. Unless otherwise provided in the applicable Award Agreement, the term
of any Non-qualified Stock Option, SAR, or RSU granted to an Independent
Director shall be ten (10) years from the date the Option is granted.

15.8 Effect of Termination of Service. Upon a termination of the Independent
Director’s services with the Company for any reason, any unvested Option or SAR
shall immediately expire and any Restricted Stock or RSU that is subject to
restrictions at the time of termination shall be forfeited and reacquired by the
Company. Vested portions of any Options granted to an Independent Director are
exercisable until the first to occur of the following events:

(i) the expiration of twelve (12) months from the date of the Independent
Director’s death or a termination of the Independent Director’s services with
the Company by reason of a Disability;

(ii) the expiration of three (3) months from the date the Independent Director’s
services with the Company are terminated for any reason other than death or
Disability; or

(iii) the expiration of ten (10) years from the date the Option was granted.

16. Recapitalization, Change In Control And Other Corporate Events

16.1 Recapitalization. If the outstanding shares of Class A Common Stock are
increased or decreased or changed into or exchanged for a different number or
kind of shares or other securities of the Company by reason of any
recapitalization, or reclassification, stock split, reverse split, combination
of shares, exchange of shares, stock dividend or other distribution payable in
capital stock of the Company or other increase or decrease in such shares
effected without receipt of consideration by the Company occurring after the
Effective Date, a corresponding appropriate and proportionate adjustment shall
be made by the Committee (i) in the aggregate number and kind of shares of
Class A Common Stock available under the Plan, (ii) in the number and kind of
shares of Class A Common Stock issuable upon exercise or vesting of an
outstanding Award or upon termination of the Restriction Period applicable to a
Restricted Stock Unit granted under the Plan, and (iii) in the exercise price
per share of outstanding Options granted under the Plan.

16.2 Reorganization. Unless otherwise provided in an Award Agreement, in the
event of a Reorganization of the Company, the Committee may, in its sole and
absolute discretion, provide on a case-by-case basis that some or all
outstanding Awards shall become immediately exercisable, vested or entitled to
payment. In the event of a Reorganization of the Company the Committee may, in
its sole and absolute discretion, provide on a case-by-case basis that Options
shall terminate upon the Reorganization, provided however, that Optionee shall
have the right, immediately prior to the occurrence of such Reorganization and
during such reasonable period as the Committee in its sole discretion shall
determine and designate, to exercise any vested Option in whole or in part. In
the event that the Committee does not terminate an Option upon a Reorganization
of the Company then each outstanding Option shall upon exercise thereafter
entitle the holder thereof to such number of shares of Class A Common Stock or
other securities or property to which a holder of shares of Class A Common Stock
would have been entitled to upon such Reorganization.

16.3 Change in Control.  

(i) Awards Other Than Performance Awards.  With respect to any Award, other than
a Performance Award, in connection with a Change in Control, the Board or
Committee may, in its discretion, either by the terms of the Award Agreement
applicable to any Award or by resolution adopted prior to the occurrence of the
Change in Control, (a) provide for the assumption or substitution of, or
adjustment to, each outstanding Award,  (b) accelerate the vesting of Awards and
terminate any restrictions on Awards,  and/or  (c) provide for the cancellation
of Awards for a cash payment per share/unit in an amount based on Fair Market
Value of the Award with reference to the Change in Control, which amount may be
zero

18

--------------------------------------------------------------------------------

 

(0) if applicable. Notwithstanding the foregoing, with respect to Awards granted
to a Participant who is an officer of the Company (each, an “Officer
Participant”), the acceleration of vesting and termination of any restrictions
shall only be provided for, if at all, with respect to such Awards, in the event
that the Officer Participant’s employment with the Company (or its successor) is
terminated either by the Company (or its successor) without Cause or by the
Officer Participant for Good Reason (x) within six months prior to the date on
which a Change in Control occurs and it is reasonably demonstrated that such
termination of employment by the Company without Cause or by the Officer
Participant for Good Reason was in contemplation of the Change in Control, or
(y) within twelve (12) months after the date of a Change in Control of the
Company.

(ii) Performance Awards.  In the event of a Change in Control, (a) any
outstanding Performance Awards relating to Performance Periods ending prior to
the Change in Control which have been earned but not paid shall become
immediately payable, (b) all incomplete Performance Periods in effect on the
date the Change in Control occurs shall end on the date of such change, and the
Committee shall, (1) determine the extent to which Qualifying Performance
Criteria with respect to each such Performance Period have been met based upon
such audited or unaudited financial information then available as it deems
relevant, (2) cause to be paid to each Participant partial or full Awards with
respect to Qualifying Performance Criteria for each such Performance Period
based upon the Committee’s determination of the degree of attainment of
Qualifying Performance Criteria, and (c) the Company shall pay all such
Performance Awards in cash promptly.

16.4 The obligations of the Company under the Plan shall be binding upon any
successor corporation or organization resulting from the merger, consolidation
or other reorganization of the Company, or upon any successor corporation or
organization succeeding to substantially all of the assets and business of the
Company. The Company agrees that it will make appropriate provisions for the
preservation of Participant’s rights under the Plan in any agreement or plan
which it may enter into or adopt to effect any such merger, consolidation,
reorganization or transfer of assets.

16.5 Adjustments. Adjustments under this Section 16 related to stock or
securities of the Company shall be made by the Committee whose determination in
that respect shall be final, binding, and conclusive. No fractional shares of
Class A Common Stock or units of other securities shall be issued pursuant to
any such adjustment, and any fractions resulting from any such adjustment shall
be eliminated in each case by rounding downward to the nearest whole share or
unit.

16.6 No Limitations. The grant of an Award pursuant to the Plan shall not affect
or limit in any way the right or power of the Company to make adjustments,
reclassifications, reorganizations or changes of its capital or business
structure or to merge, consolidate, dissolve or liquidate, or to sell or
transfer all or any part of its business or assets.

17. Provisions Applicable To Covered Employees

17.1 Awards. Notwithstanding anything in the Plan to the contrary, the Committee
may grant any Award to a Covered Employee. The Committee, in its discretion, may
determine whether an Award is to qualify as performance-based compensation as
described in Section 162(m)(4)(C) of the Code. To the extent necessary to comply
with the performance-based compensation requirements of Section 162(m)(4)(C) of
the Code, with respect to any Award granted pursuant to the Plan which may be
granted to one or more Covered Employees, no later than ninety (90) days
following the commencement of any fiscal year in question or any other
designated fiscal period or period of service (or such other time as may be
required or permitted by Section 162(m) of the Code), the Committee shall, in
writing, (i) designate one or more Covered Employees, (ii) select the Qualifying
Performance Criteria applicable to the fiscal year or other designated fiscal
period or period of service, (iii) establish the various performance targets, in
terms of an objective formula or standard, and amounts of such Awards, as
applicable, which may be earned for such fiscal year or other designated fiscal
period or period of service and (iv) specify the relationship between

19

--------------------------------------------------------------------------------

 

Qualifying Performance Criteria and the performance targets and the amounts of
such Awards, as applicable, to be earned by each Covered Employee for such
fiscal year or other designated fiscal period or period of service. Following
the completion of each fiscal year or other designated fiscal period or period
of service, the Committee shall certify in writing whether the applicable
performance targets have been achieved for such fiscal year or other designated
fiscal period or period of service. In determining the amount earned by a
Covered Employee, the Committee shall have the right to reduce (but not to
increase) the amount payable at a given level of performance to take into
account additional factors that the Committee may deem relevant to the
assessment of individual or corporate performance for the fiscal year or other
designated fiscal period or period of service.

17.2 Limitations. Furthermore, notwithstanding any other provision of the Plan
or any Award which granted to a Covered Employee and is intended to qualify as
performance-based compensation as described in Section 162(m)(4)(C) of the Code
shall be subject to any additional limitations set forth in Section 162(m) of
the Code (including any amendment to Section 162(m) of the Code) or any
regulations or rulings issued thereunder that are requirements for qualification
as performance-based compensation as described in Section 162(m)(4)(C) of the
Code, and the Plan shall be deemed amended to the extent necessary to conform to
such requirements.

18. Ownership and Transfer Restrictions

The Committee, in its sole discretion, may impose such restrictions on the
ownership and transferability of shares received pursuant to any Award at it
deems appropriate, including any restrictions as may be imposed pursuant to the
Company’s Stock Ownership Guidelines or Insider Trading Policy. Any such
restriction shall be set forth in the respective Award Agreement and may be
referred to on the certificates evidencing such shares. The holder shall give
the Company prompt notice of any disposition of shares of Class A Common Stock
acquired by exercise of an Incentive Stock Option within (i) two years from the
date of granting (including the date the Option is modified, extended or renewed
for purposes of Section 424(h) of the Code) such Option to such holder or
(ii) one year after the transfer of such shares to such holder.

19. Limitations on Re-Pricing and Exchange of Options and SARs

The approval by a majority of the votes present and entitled to vote at a duly
held meeting of the shareholders of the Company at which a quorum representing a
majority of all outstanding voting stock is, either in person or by proxy,
present and voting on the matter, or by written consent in accordance with
applicable state law and the Articles of Incorporation and Bylaws of the Company
shall be required prior to the Committee effecting any of the following: (i)
re-pricing of any Option or SAR granted under the Plan by canceling and
regranting Options or SARs or by lowering the exercise price, except for
adjustments pursuant to Section 16.1 hereof, (ii) conducting a cash buyout of
any underwater Options or SARs, (iii) replacing an underwater Option or SAR with
another Award, or (iv) taking any other action that would be treated as a
repricing under generally accepted accounting principles.  For purposes of this
Section 19, Options and SARs will be deemed to be “underwater” at any time when
the Fair Market Value of the Class A Common Stock is less than the exercise
price of the Option or SAR.

20. Disclaimer of Rights.

No provision in the Plan, any Award granted or any Award Agreement entered into
pursuant to the Plan shall be construed to confer upon any individual the right
to remain in the employ of the Company or to interfere in any way with the right
and authority of the Company either to increase or decrease the compensation of
any individual, including any Participant, at any time, or to terminate any
employment or other relationship between any individual and the Company. A
holder of an Award shall not be deemed for any purpose to be shareholder of the
Company with respect to such Award except to the extent that such Award shall
have been exercised with respect thereto and, in addition, a stock certificate
shall have

20

--------------------------------------------------------------------------------

 

been issued theretofore and delivered to the holder, or except as expressly
provided by the Committee in writing. No adjustment shall be made for dividends
(ordinary or extraordinary, whether in cash, securities or other property) or
distributions or other rights for which the record date is prior to the date
such stock certificate is issued, except as expressly provided in Section 16
hereof.

21. Nonexclusivity of the Plan. The adoption of the Plan shall not be construed
as creating any limitations upon the right and authority of the Committee to
adopt such other incentive compensation arrangements (which arrangements may be
applicable either generally to a class or classes of individuals or specifically
to a particular individual or individuals) as the Committee in its discretion
determines desirable, including, without limitation, the granting of stock
options or stock appreciation rights other than under the Plan.

22. Securities Matters

22.1 Notwithstanding anything herein to the contrary, the Company shall not be
obligated to cause to be issued or delivered any certificates evidencing the
Class A Common Stock pursuant to the Plan unless and until the Company is
advised by its counsel that the issuance and delivery of such certificates is in
compliance with all Applicable Laws, regulations of governmental authority and
the requirements of any securities exchange on which Class A Common Stock are
traded. The Committee may require, as a condition of the issuance and delivery
of certificates evidencing Class A Common Stock pursuant to the terms hereof,
that the recipient of such shares make such covenants, agreements and
representations, and that such certificates bear such legends, as the Committee,
in its sole discretion, deems necessary or desirable. To the extent that there
is not an effective registration statement available for the issuance of shares
of Class A Common Stock upon the vesting of a RSU or the exercise of an Option,
the Company may, in its sole discretion, deliver shares that are subject to
additional transferability restrictions pursuant to the Securities Act of 1933,
as amended and may make such provisions as it deems necessary to ensure
compliance by the Participant with such restrictions.

22.2 The exercise of any Option granted hereunder shall only be effective at
such time as counsel to the Company shall have determined that the issuance and
delivery of Class A Common Stock pursuant to such exercise is in compliance with
all Applicable Laws, regulations of governmental authority and the requirements
of any securities exchange on which Class A Common Stock are traded. The Company
may, in its sole discretion, defer the effectiveness of any exercise of an
Option granted hereunder in order to allow the issuance of Class A Common Stock
pursuant thereto to be made pursuant to registration or an exemption from the
registration or other methods for compliance available under federal or state
securities laws. The Company shall inform the Participant in writing of its
decision to defer the effectiveness of the exercise of an Option granted
hereunder. During the period that the effectiveness of the exercise of an Option
has been deferred, the Participant may, by written notice, withdraw such
exercise and obtain the refund of any amount paid with respect thereto.

22.3 With respect to persons subject to Section 16 of the Exchange Act,
transactions under this Plan are intended to comply with all applicable
conditions of Rule 16b-3 of the Exchange Act or its successors under the
Exchange Act. To the extent any provision of the Plan, the grant of an award, or
action by the Committee fails to so comply, it shall be deemed null and void, to
the extent permitted by law and deemed advisable by the Committee.

23. Withholding Obligation. The Committee may make such provisions and take such
steps as it may deem necessary or appropriate for the withholding of any taxes
that the Company is required by any law or regulation of any governmental
authority, whether federal, state or local, domestic or foreign, to withhold in
connection with the exercise of any Option or SAR, the vesting of any Restricted
Stock or RSU or the grant of Class A Common Stock pursuant to an Award. The
Award Agreement may provide, subject to any limitations set forth therein, that
the following forms of consideration may be used in by the Participant for
payment of any withholding due: cash or check, other Shares which have a Fair

21

--------------------------------------------------------------------------------

 

Market Value on the date of surrender equal to the amount of withholding due;
withholding of Shares deliverable upon exercise or vesting, which have a Fair
Market Value on the date of surrender equal to the amount of withholding due;
consideration received by the Company under a broker-assisted sale and
remittance program, or “cashless” exercise/sale procedure, acceptable to the
Committee; such other consideration and method of payment for the withholding
due to the extent permitted by applicable laws; or any combination of the
foregoing methods of payment.

24. Plan Construction.

24.1 Rule 16b-3. Notwithstanding any other provision of the Plan, the Plan, and
any Award granted or awarded to any individual who is then subject to Section 16
of the Exchange Act, shall be subject to any additional limitations set forth in
any applicable exemptive rule under Section 16 of the Exchange Act (including
any amendment to Rule 16b-3 of the Exchange Act) that are requirements for the
application of such exemptive rule. To the extent permitted by Applicable Laws,
the Plan and Awards granted or awarded hereunder shall be deemed amended to the
extent necessary to conform to such applicable exemptive rule. Notwithstanding
the foregoing, the Company shall have no liability to any Participant for
Section 16 consequences of awards or events under awards if an award or event
does not so qualify.

24.2 Section 162(m). Awards under Section 12 that are either granted or become
vested, exercisable or payable based on attainment of one or more performance
goals related to the Qualifying Performance Criteria that are approved by a
committee composed solely of two or more outside directors (as this requirement
is applied under Section 162(m) of the Code) shall be deemed to be intended as
performance-based compensation within the meaning of Section 162(m) of the Code
unless such committee provides otherwise at the time of grant of the award. It
is the further intent of the Company that (to the extent the Company or one of
its Subsidiaries or awards under this Plan may be or become subject to
limitations on deductibility under Section 162(m) of the Code) any such awards
and any other Performance Awards under Section 12 that are granted to or held by
a person subject to Section 162(m) will qualify as performance-based
compensation or otherwise be exempt from deductibility limitations under
Section 162(m).

24.3 Code Section 409A Compliance. The Board intends that, except as may be
otherwise determined by the Committee, any awards under the Plan are either
exempt from or satisfy the requirements of Section 409A of the Code and related
regulations and Treasury pronouncements (“Section 409A”) to avoid the imposition
of any taxes, including additional income or penalty taxes, thereunder. If the
Committee determines that an award, Award Agreement, acceleration, adjustment to
the terms of an award, payment, distribution, deferral election, transaction or
any other action or arrangement contemplated by the provisions of the Plan
would, if undertaken, cause a Participant’s award to become subject to
Section 409A, unless the Committee expressly determines otherwise, such award,
Award Agreement, payment, acceleration, adjustment, distribution, deferral
election, transaction or other action or arrangement shall not be undertaken and
the related provisions of the Plan and/or Award Agreement will be deemed
modified or, if necessary, rescinded in order to comply with the requirements of
Section 409A to the extent determined by the Committee without the content or
notice to the Participant.

24.4 No Guarantee of Favorable Tax Treatment. Although the Company intends that
awards under the Plan will be exempt from, or will comply with, the requirements
of Section 409A of the Code, the Company does not warrant that any award under
the Plan will qualify for favorable tax treatment under Section 409A of the Code
or any other provision of federal, state, local or foreign law. The Company
shall not be liable to any Participant for any tax, interest or penalties the
Participant might owe as a result of the grant, holding, vesting, exercise or
payment of any award under the Plan.

22

--------------------------------------------------------------------------------

 

25. Amendment And Termination of the Plan

25.1 Board Authorization. The Board may, at any time, terminate or, from time to
time, amend, modify or suspend this Plan, in whole or in part. No awards may be
granted during any period that the Board suspends this Plan.

25.2 Shareholder Approval. To the extent then required by Applicable Laws or any
applicable listing agency or required under Sections 162, 422 or 424 of the Code
to preserve the intended tax consequences of this Plan, or deemed necessary or
advisable by the Board, any amendment to this Plan shall be subject to
shareholder approval.

25.3 Amendments to Awards. Without limiting any other express authority of the
Committee under (but subject to) the express limits of this Plan, the Committee
by agreement or resolution may waive conditions of, or limitations on, awards to
Participants that the Committee in the prior exercise of its discretion has
imposed, without the consent of a Participant, and, subject to the requirements
of Sections 5 and 25.4, may make other changes to the terms and conditions of
awards.  Any amendment or other action that would constitute a repricing,
exchange or repurchase of an underwater Option or SAR as contemplated by Section
19 of the Plan is subject to the limitations set forth therein.

25.4 Limitations on Amendments to Plan and Awards. No amendment, suspension or
termination of this Plan or change of or affecting any outstanding award shall,
without written consent of the Participant, affect in any manner materially
adverse to the Participant any rights or benefits of the Participant or
obligations of the Company under any award granted under this Plan prior to the
effective date of such change.

25.5 Suspension or Termination of Award. In addition to the remedies of the
Company elsewhere provided for herein, failure by a Participant to comply with
any of the terms and conditions of the Plan or the Award Agreement executed by
such Participant evidencing an award, unless such failure is remedied by such
Participant within ten days after having been notified of such failure by the
Committee, shall be grounds for the cancellation and forfeiture of such award,
in whole or in part, as the Committee may determine.

26. Notices

Any communication or notice required or permitted to be given under the Plan
shall be in writing, and mailed by registered or certified mail or delivered by
hand, if to the Company, to its principal place of business, attention: Stock
Option Administrator, and if to the Participant, to the address of the
Participant as appearing on the records of the Company.

27. Stock-Based Awards in Substitution for Stock Options or Awards Granted by
Other Company.

Awards may be granted to Eligible Individuals in substitution for or in
connection with an assumption of Options, SARs, a Restricted Stock Award or
other stock-based awards granted by other entities to persons who are or who
will become Eligible Individuals in respect of the Company or one of its
Subsidiaries, in connection with a distribution, merger or other reorganization
by or with the granting entity or an affiliated entity, or the acquisition by
the Company or one of its Subsidiaries, directly or indirectly, of all or a
substantial part of the stock or assets of the employing entity. The awards so
granted need not comply with other specific terms of this Plan, provided the
awards reflect only adjustments giving effect to the assumption or substitution
consistent with the conversion applicable to the Class A Common Stock in the
transaction and any change in the issuer of the security. Any shares that are
delivered and any awards that are granted by, or become obligations of, the
Company, as a result of the assumption by the Company of, or in substitution
for, outstanding awards previously granted by an acquired company (or previously
granted by a predecessor employer (or direct or indirect parent thereof) in the
case of persons that become employed by the Company or one of its Subsidiaries
in connection with a business or asset acquisition or

23

--------------------------------------------------------------------------------

 

similar transaction) shall not be counted against the Share Limit or other
limits on the number of shares available for issuance under this Plan. Any
adjustment, substitution or assumption made pursuant to this Section 27 shall be
made in a manner that, in the good faith determination of the Committee, will
not likely result in the imposition of additional taxes or interest under
Section 409A of the Code.

28. Governing Law; Severability

28.1 Violations of Law. The Company shall not be required to sell or issue any
shares of Class A Common Stock under any Award if the sale or issuance of such
shares would constitute a violation by the individual holding the Award, the
Participant or the Company of any provisions of any law or regulation of any
governmental authority, including without limitation any federal or state
securities laws or regulations. Any determination in this connection by the
Committee shall be final, binding, and conclusive. The Company shall not be
obligated to take any affirmative action in order to cause the exercisability or
vesting of an Option, the exercise of an Option or the issuance of shares
pursuant to the exercise of an Option or expiration of a Restriction Period to
comply with any law or regulation of any governmental authority.

28.2 Governing Law. This Plan shall be governed by, and construed and enforced
in accordance with, the laws of the State of Florida, without regard to
conflicts of laws thereof.

28.3 Severability. If any provision of the Plan or any Award Agreement shall be
determined to be illegal or unenforceable by any court of law in any
jurisdiction, the remaining provisions hereof and thereof shall be severable and
enforceable in accordance with their terms, and all provisions shall remain
enforceable in any other jurisdiction.
