| | (a) | Tax Consequences. The Grantee acknowledges that it shall recognize ordinary income at the times the Restrictions lapse with respect to the Shares in an amount equal to the
fair market value of the Shares on each such date and the Company shall be required to collect all applicable withholding taxes with respect to such income. The obligations of the Company under the Plan are conditioned on the Grantee making
arrangements for the payment of any such taxes. Notwithstanding anything herein to the contrary, the release of the Shares from the Restrictions shall be conditioned upon the Grantee making adequate provision for federal, state or other tax
withholding obligations, if any, which arise upon such release (unless the Section 83(b) election described in Section 5(b) hereof has been filed), whether by withholding, direct payment to the Company, or otherwise.

| | (b) | Section 83(b) Election. The Grantee acknowledges that he has been informed that he may file with the Internal Revenue Service within 30 days of the Grant Date an
election, pursuant to Section 83(b) of the Internal Revenue Code of 1986, as amended (the Code), to be taxed currently on the fair market value of the Shares on the Grant Date. The Grantee acknowledges that it is the Grantees
sole responsibility to file timely the election under Section 83(b) of the Code, even if the Grantee requests the Company or its representative to make this filing on the Grantees behalf.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | No Tax Advice. By signing this Agreement, the Grantee represents that he has reviewed with his own tax advisors the federal, state, local and foreign tax consequences of the
transactions contemplated by this Agreement and that he is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. The Grantee understands and agrees that he (and not the Company) shall be
responsible for any tax liability that may arise as a result of the transactions contemplated by this Agreement.
