Act of 1934 (1934 Act) shall, as a result of a tender or exchange offer, open
market purchases, privately negotiated purchases or otherwise, have become the

Securities.

 

4. No Voting or Dividend Rights.

until the underlying Common Stock is issued to the Recipient.

 

5. Non-Assignability of RSUs.

The RSUs may not be assigned or transferred except on death, by will or
operation of law.

 

6. Delivery of Shares.

As soon as practicable on or after the date on which the RSUs become vested, the
Company will issue to the Recipient the number of shares of Common Stock
underlying the RSUs that vested, and will deliver such shares to a brokerage
account established by the Recipient in accordance with instructions from the
Company or in such other manner as may be determined by the Company.

 

7. Changes in Capital Structure.

If, prior to the full vesting of all the RSUs awarded under this Agreement, the
outstanding shares of Common Stock of the Company 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, reclassification,
stock split, combination of shares, or dividend payable in shares, appropriate
adjustment shall be made by the Compensation Committee of the Company’s Board of
Directors (the “Administrator”) in the number and kind of shares subject to the
unvested RSUs under this Agreement so that the Recipient’s proportionate
interest before and after the occurrence of the event is maintained. Fractional
shares will be disregarded. Any such adjustment made by the Administrator shall
be conclusive.

 

8. Successorship.

Subject to the limits in 2.1, this Agreement will be binding upon and benefit
the parties, their successors and assigns.
