Calculation. Landlord and Tenant are knowledgeable and experienced in commercial transactions and agree that each the provision of this Lease for determining charges, amounts and additional rent payable by Tenant # is commercially reasonable and valid even though such methods may not state a precise mathematical formula for determining such charges and # constitutes a “method by which the charge is to be computed” for purposes of Section 93.004 of the Texas Property Code.

No fraction of a share of Buyer Common Stock will be issued by virtue of the Transaction. Any Seller who would otherwise be entitled to receive a fraction of a share of Buyer Common Stock shall receive an amount of cash equal to the product obtained by multiplying # such fraction by # the Average Trading Price, rounded to the nearest whole cent.

Calculation. Bonuses and applicable bonus metrics will be determined from time to time by the Compensation Committee of the Company’s Board of Directors (the “Compensation Committee”). Bonuses may be calculated from individual or company performance criteria including, without limitation, revenue, annual revenue run-rate, net revenue retention, adjusted EBITDA, adjusted EBITDA margin, gross profit, non-GAAP operating income, or management-based objectives.
