Any vested portion of the Option will lapse and expire prior to the Expiration Date in the event of the termination of Optionee’s Continuous Service for any reason according the following schedule (but in no event shall an Option survive the Expiration Date): (a) if Optionee’s Continuous Service terminates because of Optionee’s death or Disability, then the Option will expire 180 days after the date of such death or Disability, (b) if Optionee’s Continuous Service terminates because of Optionee’s discharge for Cause, then the Option will expire immediately upon such termination, (c) if Optionee’s Continuous Service terminates because of Optionee’s resignation (other than a resignation with Good Reason), then the Option will expire on the effective date of such termination, and (d) if Optionee’s Continuous Service terminates because of any reason other than Optionee’s death, Disability, discharge for Cause or resignation (other than with Good Reason), then the Option will terminate 90 days after the date of such termination.

If the person exercising an Option is not Optionee, such person shall also deliver with the notice of exercise appropriate proof acceptable to the Secretary of his or her right to hold and exercise the Option. Payment for such Units shall be (a) in cash, (b) by delivery (actual or by attestation) of Units previously acquired by the purchaser, (c) by withholding of Units from the Option, or (d) any combination thereof, for the number of Units specified in such written notice. The value of Units surrendered or withheld for this purpose shall be the Fair Market Value as of the last trading day immediately prior to the exercise date.

5. Withholding. The Company or any employer Affiliate has the authority and the right to deduct or withhold, or require Optionee to remit to the employer, an amount sufficient to satisfy federal, state, and local taxes (including Optionee’s FICA obligation) required by law to be withheld with respect to any taxable event arising as a result of the exercise of the Option. The withholding requirement may be satisfied, in whole or in part, at the election of the Company, by withholding from the Option Units having a Fair Market Value on the date of withholding equal to the minimum amount (and not any greater amount) required to be withheld for tax purposes, all in accordance with such procedures as the Company establishes. The obligations of the Company under this Award Certificate will be conditional on such payment or arrangements, and the Company, and, where applicable, its Affiliates will, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to Optionee.

6. Limitation of Rights. The Option does not confer to Optionee or Optionee’s beneficiary designated pursuant to the Plan any rights of a Member or other holder of Units of the Company unless and until Units are in fact issued to such person in connection with the exercise of the Option. Nothing in this Award Certificate shall interfere with or limit in any way the right of the Company or any Affiliate to terminate Optionee’s service at any time, nor confer upon Optionee any right to continue in the service of the Company or any Affiliate.

7. Restrictions on Transfer and Pledge. No right or interest of a Participant in any Award may be pledged, encumbered, or hypothecated to or in favor of any party other than the Company or an Affiliate, or shall be subject to any lien, obligation, or liability of such Participant to any other party other than the Company or an Affiliate. No Award shall be assignable or transferable by a Participant other than by will or the laws of descent and distribution; provided, however, the Board may (but need not) permit other transfers where the Board provides prior written consent after concluding that such transferability does not result in accelerated taxation and is otherwise appropriate and desirable, taking into account any factors deemed relevant, including without limitation, state or federal tax or securities laws applicable to transferable Options. Any assignment, transfer, pledge, encumbrance or hypothecation of any Award not permitted by this Section 7 shall, automatically and without further action by any person or entity, result in the immediate forfeiture and cancellation of such Award without consideration. The Option may be exercised during the lifetime of Optionee only by Optionee or any permitted transferee.

8. Restrictions on Issuance of Units. If at any time the Board shall determine in its discretion, that registration, listing or qualification of the Units covered by the Option upon any securities exchange or under any foreign, federal, or local law or practice, or the consent or approval of any governmental regulatory body, is necessary or desirable as a condition to the exercise of the Option, the Option may not be exercised in whole or in part unless and until such registration, listing, qualification, consent or approval shall have been effected or obtained free of any conditions not acceptable to the Board.

9. Plan Controls. The terms contained in the Plan are incorporated into and made a part of this Award Certificate and this Award Certificate shall be governed by and construed in accordance with the Plan.
