In addition, all remaining accumulated payroll deduction amounts shall be returned to the participant. 

For purposes ofthis paragraph 18, an option granted under the Plan shall be deemed to be assumed if the option is replaced with a comparable option with respect to shares of capital stock of the successor corporation or parent thereof. The determination of optioncomparability shall be made by the Board and its determination shall be final, binding and conclusive on all persons. 

The Board may, if itso determines in the exercise of its sole discretion, also make provision for adjusting the Reserves, as well as the price per share of Common Stock covered by each outstanding option, in the event that the Company effects one or morereorganizations, recapitalizations, rights offerings or other increases or reductions of shares of its outstanding Common Stock, and in the event of the Company being consolidated with or merged into any other corporation.
