 will be required for any amendment to the extent required by applicable laws. No amendment, alteration, suspension or termination of the Amended and Restated Plan
will materially impair the rights of any participant, unless mutually agreed otherwise between the participant and the Administrator and which agreement must be in writing and signed by the participant and us.

Federal Tax Aspects

The following paragraphs are a
summary of the general federal income tax consequences to U.S. taxpayers and us of Awards granted under the Amended and Restated Plan. Tax consequences for any particular individual may be different.

Incentive Stock Options. A participant recognizes no taxable income for federal income tax purposes as a result of the grant or exercise of an
option that qualifies as incentive stock option under Section 422 of the Code. If a participant exercises the option and then later sells or otherwise disposes of the shares acquired through the exercise the option after both the two-year anniversary of the date the option was granted and the one-year anniversary of the exercise, the participant will
recognize a capital gain or loss equal to the difference between the sale price of the shares and the exercise price, and the combined company will not be entitled to any deduction for federal income tax purposes.

However, if the participant disposes of such shares either on or
before the two-year anniversary of the date of grant or on or before the one-year anniversary of the date of exercise (referred
to as a “disqualifying disposition”), any gain up to the excess of the fair market value of the shares on the date of exercise over the exercise price generally will be taxed as ordinary income, unless the shares are disposed of in a
transaction in which the participant would not recognize a loss (such as a gift). Any gain in excess of that amount will be a capital gain. If a loss is recognized, there will be no ordinary income, and such loss will be a capital loss. Any ordinary
income recognized by the participant upon the disqualifying disposition of the Shares generally should be deductible by the combined company for federal income tax purposes, except to the extent such deduction is limited by applicable provisions of
the Code.

For purposes of the alternative minimum tax, the difference between the option exercise price and the fair market value of the shares on the
exercise date is treated as an adjustment item in computing the participant’s alternative minimum taxable income in the year of exercise. In addition, special alternative minimum tax rules may apply to certain subsequent disqualifying
dispositions of the shares or provide certain basis adjustments or tax credits
