WHEREAS, the Company has determined that it is desirable and in its best interests to grant the Optionee, pursuant to the Plan, an option to purchase a certain number of shares of Stock, in order to provide the Optionee with an incentive to advance the interests of the Company, all according to the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the mutual promises and covenants contained herein, the parties hereto do hereby agree as follows:

1                  GRANT OF NON-QUALIFIED STOCK OPTION

The Company hereby grants to the Optionee the right and option (the “Option”) to purchase from the Company, on the terms and subject to the conditions set forth in the Plan and in this Option Agreement, _________ shares of Class A Common Stock (“the Stock”).  The Date of Grant of this Option is _________.  This Option shall not constitute an incentive stock option within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”).

2.                 TERMS OF PLAN

The Option granted pursuant to this Option Agreement is granted subject to the terms and conditions set forth in the Plan, a copy of which is enclosed with this Option Agreement.  All terms and conditions of the Plan, as may be amended from time to time, are hereby incorporated into this Option Agreement by reference and shall be deemed to be part of this Option Agreement, without regard to whether such terms and conditions (including, for example, provisions relating to certain adjustments  in capitalization of the Company) are not otherwise set forth in this Option Agreement.  In the event that there is any conflict or inconsistency between the provisions of this Option Agreement and of the Plan, the provisions of the Plan shall govern.

3.                 EXERCISE PRICE

The Exercise Price for the shares of Stock subject to the Option granted by this Option Agreement is $__________ per share.

4.                 EXERCISE OF OPTION

Except as otherwise provided herein, and subject to the provisions of the Plan (including restrictions on the transferability of the Option and special provisions relating to exercise or termination of the Option following the Optionee’s termination of employment, disability, death or retirement or certain changes in capitalization of the Company), the Option granted pursuant to this Option Agreement shall be subject to exercise as follows:

4.1              Time of Exercise of Option

The Option will not be excercisable prior to the first anniversary of the Option Grant Date.  After the first anniversary of the Option Grant Date, the Option will be fully vested and the Optionee may purchase up to 100% of the shares of Stock available for purchase under the Option; provided, that no single exercise of the Option shall be for less than 100 shares, unless at the time of the exercise, the maximum number of shares available for purchase under the Option is less than 100 shares.  In no event shall the Option be exercised for a fractional share.

4.2              Acceleration of Options

In accordance with the provisions of the Plan, Options granted under this Option Agreement shall become immediately exercisable upon the occurrence of a Change in Control of the Corporation if the Optionee holding such Option is a Non-Employee Director of the Company or any subsidiary of the Company on the date of the consummation of such Change in Control.

4.3              Termination of Option

The Option shall terminate upon the earlier of the expiration of a period of (i) ten years from the Date of Grant, or (ii) one month from the date of the Optionee’s termination of service as a Non-Employee Director; provided, however, and subject to all Plan provisions relating to termination, that if such termination of service as a Non-Employee Director falls within the scope of one of the provisions of the Plan providing for an extended exercise period in excess of one month, the Option shall terminate upon the expiration of the extended period, as specified in such provision, after the Optionee’s termination of service as a Non-Employee Director with the Company or a subsidiary within which the Option is exercisable.

4.4              Effect of Optionee’s Disability or Death

If the Optionee ceases to be a Non-Employee Director of the Company or a subsidiary of the Company by reason of Disability, the unexercised portion of any Option held by such Optionee at that time will become immediately vested and will be exercisable for the shorter of one year from the date on which the Optionee ceased to serve as a Non-Employee Director or the remaining Option term.  If the Optionee does not exercise the Option within the time specified, such Option shall terminate.  The Company shall have the authority to determine the date an Optionee ceases to serve as a Non-Employee Director by reason of Disability.

If the Optionee dies while serving as a Non-Employee Director of the Company or a subsidiary of the Company (or dies within a period of one month after termination of his service as a Non-Employee Director for any reason other than Disability or within a period of one year after termination of his service as Non-Employee Director by reason of Disability), the unexercised portion of any Option held by such Optionee at the time of death will become immediately vested and will be exercisable for the shorter of one year from the date of such Optionee’s death, or the remaining Option term.  Such Option may be exercised by the executor or administrator of the Optionee’s estate or by any person or persons who shall have acquired the Option directly from the Optionee by bequest or inheritance.  If the Option is not exercised within the time specified, such Option shall terminate.

4.5              Limitations on Exercise of Option

Notwithstanding the foregoing subsections, in no event may the Option be exercised, in whole or in part, after ten years following the Date of Grant, or after the occurrence of an event that results in termination of the Option under the Plan.

4.6              Method of Exercise of Option

Cash Exercise (to exercise and retain the Shares):  Subject to the terms and conditions of this Option Agreement and the Plan, the Option may be exercised by delivering written notice of exercise to the Company, at its principal office, addressed to the attention of Stock Plan Administration, or to the agent/broker designated by the Company, which notice shall specify the number of shares for which the Option is being exercised, and shall be accompanied by payment in full of the Exercise Price of the shares for which the Option is being exercised plus the full amount of all applicable withholding taxes due on the Option exercise.  Payment of the Exercise Price for the shares of Stock purchased pursuant to the exercise of the Option shall be made either in cash or by certified check payable to the order of the Company.  If the person exercising the Option is not the Optionee, such person shall also deliver with the notice of exercise appropriate proof of his or her right to exercise the Option, as the Company may require in its sole discretion.  Promptly after exercise of the Option as provided for above, the Company shall deliver to the person exercising the Option a certificate or certificates for the shares of Stock being purchased.

Same-Day-Sale Exercise (to exercise and immediately sell all the Shares):  Subject to the terms and conditions of this Option Agreement and the Plan, the Option may be exercised by delivering written notice of exercise to the agent/broker designated by the

3

Company, which notice shall specify the number of shares for which the Option is being exercised and irrevocable instructions to promptly (1) sell all of the shares of Stock to be issued upon exercise and (2) remit to the Company the portion of the sale proceeds sufficient to pay the Exercise Price for the shares of Stock purchased pursuant to the exercise of the Option and all applicable taxes due on the Option exercise.  The agent/broker shall request issuance of the shares and immediately and concurrently sell the shares on the Optionee’s behalf.  Payment of the Exercise Price for the shares of Stock purchased pursuant to the exercise of the Option, any brokerage fees, transfer fees, and all applicable taxes due on the Option exercise, shall be deducted from the proceeds of the sale of the shares.  If the person exercising the Option is not the Optionee, such person shall also deliver with the notice of exercise appropriate proof of his or her right to exercise the Option, as the Company may require in its sole discretion.  Promptly after exercise of the Option as provided for above, the agent/broker shall deliver to the person exercising the Option the net proceeds from the sale of the shares of Stock being exercised and sold.

Sell-to-Cover Exercise (to exercise and immediately sell a portion of the Shares):  Subject to the terms and conditions of this Option Agreement and the Plan, the Option may be exercised by delivering written notice of exercise to the agent/broker designated by the Company, which notice shall specify the number of shares for which the Option is being exercised and irrevocable instructions to promptly (1) sell the portion (which must be a whole number) of the shares of Stock to be issued upon exercise sufficient to generate proceeds to pay the Exercise Price for the shares of Stock purchased pursuant to the exercise of the Option, any brokerage or transfer fees, and all applicable taxes due on the Option exercise (collectively the “Exercise Costs”) and (2) remit to the Company a sufficient portion of the sale proceeds to pay the Exercise Price for the shares of Stock purchased pursuant to the exercise of the Option and all applicable taxes due on the Option exercise.  The agent/broker shall request issuance of the shares and immediately and concurrently sell on the Optionee’s behalf only such number of the Shares as is required to generate proceeds sufficient to pay the Exercise Costs.  Promptly after exercise of the Option as provided for above, the Company shall deliver to the person exercising the Option a certificate for the shares of Stock issued upon exercise which are not sold to pay the Exercise Costs.  Promptly after exercise of the Option as provided for above, the agent/broker shall deliver to the person exercising the Option any net proceeds from the sale of the Shares in excess of the Exercise Costs.  If the person exercising the Option is not the Optionee, such person shall also deliver with the notice of exercise appropriate proof of his or her right to exercise the Option, as the Company may require in its sole discretion.

The Option shall not be exercisable if and to the extent the Company determines such exercise or method of exercise would violate applicable securities laws, the rules and regulations of any securities exchange or quotation system on which the Stock is listed, or the Company’s policies and procedures.  An attempt to exercise the Option granted hereunder other than as set forth above shall be invalid and of no force and effect.

4.7              Parachute Limitations

Notwithstanding any other provision of this Option Agreement or the Plan or any other agreement, contract or understanding heretofore or hereafter entered into by the

4

Optionee with the Company (or any subsidiary or affiliate thereof), except an agreement, contract or understanding hereafter entered into that expressly modifies or excludes application of this subsection (the “Other Agreements”), and notwithstanding any formal or informal plan or other arrangements heretofore or hereafter adopted by the Company (or any such subsidiary or affiliate) for the direct or indirect compensation of the Optionee (including groups or classes of participants or beneficiaries of which the Optionee is a member), whether or not such compensation is deferred, is in cash, or is in the form of a benefit to or for the Optionee (the “Other Benefit Plans”), the Optionee shall not have any right to exercise an Option or receive any payment or other benefit under this Option Agreement, any Other Agreement, or any Other Benefit Plan if such right to exercise, payment or benefit, taking into account all other rights, payments or benefits to or for the Optionee under this Option Agreement, all Other Agreements and all Other Benefit Plans, would cause any right, payment or benefit to the Optionee under this Option Agreement to be considered a “parachute payment” within the meaning of Section 280G(b)(2) of the Code as then in effect (a “Parachute Payment”).  In the event that the receipt of any such right to exercise or any other payment or benefit under this Option Agreement, any Other Agreement or any Other Benefit Plan would cause the Optionee to be considered to have received a Parachute Payment under this Agreement, then the Optionee shall have the right, in the Optionee’s sole discretion, to designate those rights, payments or benefits under this Option Agreement, any Other Agreements, and/or any Other Benefit Plans, which should be reduced or eliminated so as to avoid having the right, payment or benefit to the Optionee under this Option Agreement be deemed to be a Parachute Payment.

5.                 TRANSFERABILITY OF OPTIONS

During the lifetime of an Optionee, only such Optionee (or, in the event of legal incapacity or incompetency, the Optionee’s guardian or legal representative) may exercise the Option.  No Option shall be assignable or transferable by the Optionee to whom it is granted, other than by will or the laws of descent and distribution.

6.                 RIGHTS AS STOCKHOLDER

Neither the Optionee nor any executor, administrator, distributee or legatee of the Optionee’s estate shall be, or have any of the rights or privileges of, a stockholder of the Company in respect of any shares of Stock issuable hereunder unless and until such shares have been fully paid and certificates representing such shares have been endorsed, transferred and delivered, and the name of the Optionee (or of such personal representative, administrator, distributee or legatee of the Optionee’s estate) has been entered as the stockholder or record on the books of the Company.

7.                 WITHHOLDING OF TAXES

The parties hereto recognize that the Company or a subsidiary may be obligated to withhold federal, state and/or local income taxes and Social Security taxes to the extent that the Optionee realizes ordinary income in connection with the exercise of the Option or in connection with a disposition of any shares of Stock acquired by exercise of the

5

Option. The Optionee agrees that the Company or a subsidiary may withhold amounts needed to cover such taxes from payments otherwise due and owing to the Optionee, and also agrees that upon demand the Optionee will promptly pay to the Company or a subsidiary having such obligation any additional amounts as may be necessary to satisfy such withholding tax obligation.  Such payment shall be made in cash or by check payable to the order of the Company or a subsidiary.

8.                 DISCLAIMER OF RIGHTS

No provision in this Option Agreement shall be construed to confer upon the Optionee the right to be employed by the Company or any subsidiary, or to interfere in any way with the right and authority of the Company or any subsidiary either to increase or decrease the compensation of the Optionee at any time, or to terminate any employment or other relationship between the Optionee and the Company or any subsidiary.

9.                 INTERPRETATION OF THIS OPTION AGREEMENT

All decisions and interpretations made by the Board or the Compensation Committee thereof with regard to any question arising under the Plan or this Option Agreement shall be binding and conclusive on the Company and the Optionee and any other person entitled to exercise the Option as provided for herein.

10.              GOVERNING LAW

This Option Agreement shall be governed by the laws of the State of Delaware (but not including the choice of law rules thereof).

11.              BINDING EFFECT

Subject to all restrictions provided for in this Option Agreement, the Plan, and by applicable law relating to assignment and transfer of this Option Agreement and the Option provided for herein, this Option Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective heirs, executors, administrators, successors and assigns.

12.              NOTICE

Any notice hereunder by the Optionee to the Company shall be in writing and shall be deemed duly given if mailed or delivered to the Company at its principal office, addressed to the attention of Stock Plan Administration or if so mailed or delivered to such other address as the Company may hereafter designate by notice to the Optionee.  Any notice hereunder by the Company to the Optionee shall be in writing and shall be

6

deemed duly given if mailed or delivered to the Optionee at the address specified below by the Optionee for such purpose, or if so mailed or delivered to such other address as the Optionee may hereafter designate by written notice given to the Company.

13.              ENTIRE AGREEMENT

This Option Agreement and the Plan together constitute the entire agreement and supersede all prior understandings and agreements, written or oral, of the parties hereto with respect to the subject matter hereof.  Except for amendments to the Plan incorporated into this Option Agreement by reference pursuant to Section 2 above, neither this Option Agreement nor any term hereof may be amended, waived, discharged or terminated except by a written instrument signed by the Company and the Optionee; provided, however, that the Company unilaterally may waive any provision hereof in writing to the extent that such waiver does not adversely affect the interests of the Optionee hereunder, but no such waiver shall operate as or be construed to be a subsequent waiver of the same provision or a waiver of any other provision hereof.
