                                                                    PAGE 3 OF 13

      original Order or at any time prior to expiration of the standard Warranty
      Period. The second year of EWMP may be purchased on the original Order or
      at any time prior to the expiration of either the standard Warranty Period
      or prior to the expiration of first-year EWMP if this option was selected.

            Software: Annual fee is 12% of the total per-Order Software price

      purchased on the original Order or at any time prior the expiration of the
      standard Warranty Period. Additional years of EWMP may be purchased at any
      time prior to expiration of the then-current year of EWMP. Elastic may

      chooses not to remain within Supported Releases of the currently available
      Software; and/or .2) Reseller or its Customer chooses not to obtain
      upgraded Hardware required to run such Supported Releases.

      At Elastic's request, Reseller agrees to provide information and
documentation deemed sufficient by Elastic to determine the validity of any
warranty claims or issuance by Reseller of Major Releases to Customers under
EWMP. Such information and documentation may include, but is not limited to,
copies of Customer receipts or other documents showing that EWMP fees were paid
and identifying the Products by name, quantity and serial number to which EWMP
applies. Elastic may refuse EWMP warranty claims and prohibit Reseller from
issuing Major Releases under EWMP if Reseller refuses to supply such information
and documentation upon request by Elastic.

labor to install Products; on-site Product support; support or replacement of
Product that is altered, modified, mishandled, destroyed, or damaged by natural
causes or damaged during unauthorized use; Services to resolve problems

Technical Support Rate as listed in the Exhibit A Price List and as amended from
time to time upon 60 days written notice to Reseller and reimburse Elastic for
all material and travel expenses.

companies, or its licensors be liable to Reseller or any third party for

(including legal fees and expenses) or loss of goodwill or profit in connection
with the supply, use or performance of or inability to use the Products or any
services provided hereunder, or in connection with any claim arising from this
Agreement, even if Elastic, its subsidiaries, its associated companies, or its

ASSIGNS, ITS SUBSIDIARIES, OR ITS AFFILIATES BE LIABLE TO RESELLER OR ANY THIRD
