1. GRANT OF LICENSE.

TuxCare hereby grants to you, and you accept, a limited, nonexclusive license to use the
Programs in machine-readable, object code form only, and the user manuals accompanying the
Programs (the “Documentation”), only as authorized in this License Agreement. For purposes of
this License Agreement, the “Programs” include any updates, enhancements, modifications,
revisions, or additions to the Programs made by TuxCare and made available to end-users.
Notwithstanding the foregoing, TuxCare shall be under no obligation to provide any updates,
enhancements, modifications, revisions, or additions to the Programs.

You may use one copy of the Programs only on systems, including servers, workstations, virtual
machines, blades, nodes, or disk partitions for which you have purchased Subscription Services
from TuxCare or its resellers. For purposes of this License Agreement, “use” of the Programs
means loading the Programs into the temporary or permanent memory of a computer.
Installation of the Programs on a network server solely for distribution to other computers is not
“use” of the Programs and is permitted as long as you have purchased Subscription Services for
the systems being accessed by the Programs.

Your installation or use of the Programs grants TuxCare limited access to your system
information for the sole purpose of Cybersecurity analysis and reporting. Such access and
information collected include reviewing installed packages and applications, the names, sizes,
and attributes of files, the server or system uptime, load, running processes, and debugging
information of the patching process and Program.
As a condition of the license granted to You pursuant to this License Agreement, You shall pay
TuxCare the amount(s) of all applicable license fees. You shall, in addition to the license fees,
pay all applicable sales, use, transfer, or other taxes and all duties, whether national, state, or
local, however designated, that are levied or imposed by reason of the transaction contemplated
under this License Agreement. You shall reimburse TuxCare for the amount of any such taxes
or duties paid or incurred directly by TuxCare as a result of this transaction, and you agree that
TuxCare may charge any such reimbursable taxes to the payment instrument you used for Your
initial payment.

Restrictions on Use with cPanel and Plesk: Notwithstanding any other provisions in this
License Agreement, licenses for Endless Lifecycle Support (ELS) for CloudLinux 7 and ELS for
CentOS 7, when procured directly from TuxCare, shall not be used on systems running cPanel
or Plesk. For systems utilizing cPanel or Plesk, licensing for ELS must be procured through
WebPros or its authorized distributors. Any use of directly procured TuxCare ELS licenses on
such systems constitutes a breach of this License Agreement.

2. AUDIT

You agree that on TuxCare’s request, you will certify in writing your compliance with the terms of
this License Agreement, including your use of the Programs only on or in connection with the
number of systems licensed. You further agree that TuxCare may, during normal business hours
and with reasonable prior notice, request and gain access to your premises for the limited
purpose of conducting an inspection to determine and verify your compliance with this License
