 ii. the product of: (A) the number of eligible
*** Adult Dependent Users each month; and (B) the per *** Adult Dependent User rate of $*** (the “Monthly *** Dependent Fee”); plus 

iii. the product of: (A) the number of eligible *** Users each month (which is the sum of the *** Employee Users and the *** Adult

 7

eligibility file run on the 15th day of a month (the “Billing File Run”) he/she will be included in Customer’s self-billing process and will be deemed a User for the full month, even if the User was only a User for a portion of that
month. 
 d. Calculation of Service Fee. On a set date each month, Customer will determine the number of *** Employee Users, ***
Adult Dependent Users, *** Users and *** Users who meet the Eligibility Criteria, and Customer ‘will calculate the full fee payable for such *** Employee Users, *** Adult Dependent Users, *** Users and *** Users, as applicable, for such month.
Customer will report results of each monthly Billing File Run and the related full fee payable to Castlight by the last day of such applicable month. Castlight may verify the amount calculated by Customer by comparing the number in the Billing File
Run for the applicable month to the eligibility file run with the date closest to the Billing File Run for the applicable month. A variance of up to I% is acceptable with no risk for payment adjustments. 

11. PAYMENT AND INVOICES. Customer’s payment to Castlight for the Service Fee will be due no later than thirty (30) days after the end of
each month. Castlight will calculate and invoice the Customer Support Fee, if any, each month for the prior month. For all other fees (or if there are no more invoices for the Customer Support Fee), Castlight will invoice Customer and payment will
be due thirty (30) days after Customer’s receipt of each invoice. If any charge owing by Customer (other than charges disputed in good faith) is 30 days or more overdue, Castlight may, without limiting its other rights and remedies, suspend the
Castlight Service until such amounts are paid in full. Additionally, all amounts not paid when due will accrue interest (without the requirement of a notice) at the lower of 1.5% per month or the highest rate permissible by law until the unpaid
amounts are paid in full. 
 12. TERM. This First Addendum shall terminate upon the termination of the MSA unless otherwise mutually agreed by the
parties.
