A10 NETWORKS, INC. VTHUNDER® SOFTWARE LICENSE AGREEMENT PLEASE READ THE FOLLOWING TERMS AND CONDITIONS CAREFULLY BEFORE INSTALLING OR USING THE VTHUNDER® SOFTWARE (INCLUDING MAINTENANCE RELEASES, IF ANY) OR ANY A10 NETWORKS DOCUMENTATION (COLLECTIVELY, THE “SOFTWARE”). THE TERMS AND CONDITIONS OF THIS SOFTWARE LICENSE AGREEMENT (“AGREEMENT”) GOVERN USE OF THE SOFTWARE UNLESS CUSTOMER AND A10 NETWORKS, INC. (“A10 NETWORKS”) HAVE EXECUTED A SEPARATE AGREEMENT GOVERNING USE OF THE SOFTWARE. A10 Networks is willing to license the Software to Customer only upon the condition that Customer accepts all the terms contained in this Agreement. If Customer installs or uses the Software or keeps it for 30 days after the date of purchase (or the date of delivery, if A10 Networks has made the Software available to Customer without charge), then Customer has indicated that Customer understands this Agreement and accept all of its terms. If you are accepting the terms of this Agreement on behalf of a company or other legal entity, you represent and warrant that you have the authority to bind that company or other legal entity to the terms of this Agreement, and, in such event, “Customer” will refer to that company or other legal entity. If Customer does not accept all the terms of this Agreement, then A10 Networks is unwilling to license the Software to Customer, and Customer must return the Software to A10 Networks for a full refund, if Customer has paid for the license to the Software, or, if A10 Networks has made the Software available to Customer without charge, Customer must destroy all copies of the Software. Customer’s right to return the Software for a refund expires 30 days after the date of purchase. 1. Grant of License. Conditioned upon Customer’s compliance with the terms and conditions of this Agreement, A10 Networks grants Customer a non-exclusive and non-transferable license for Customer to Execute (as defined herein) a single instance with a unique identifier (UID) of the executable form of the Software on a single hypervisor, solely for Customer’s internal business purposes and solely for the purpose of further optimizing Customer network, which may include providing hosting, application, service bureau, or software-as-a-service (SaaS) services to third parties. Notwithstanding the foregoing, if Customer has downloaded a trial version and has not paid the license fees, Customer’s license is limited to use for Customer internal business purposes solely in a non-production environment, and solely for the purpose of evaluating whether Customer will purchase a production-environment use license. Customer may make copies of the Software for backup purposes; provided that Customer reproduces on it all copyright and other proprietary notices that are on the original copy of the Software. A10 Networks reserves all rights in the Software not expressly granted to Customer in this Agreement. For purposes of this Agreement, “Execute” and “Execution” means to load, install, and run the Software in order to benefit from its functionality as designed by A10 Networks. “Software” means the current version of the vThunderTM Software associated with this Agreement, together with any Maintenance Releases provided to the Customer pursuant to this Agreement. “Maintenance Release” means any update or release of the Software that A10 Networks may provide to the Customer from time to time during the Term, that may contain, among other things, error corrections, enhancements or other changes to the user interface, functionality, compatibility, capabilities, performance, efficiency or quality of the Software, but does not constitute a New Version. “New Version” means any new version of the Software that A10 Networks may from time to time introduce and market generally as a distinct licensed product, and which A10 Networks may make available to the Customer at an additional cost under a separate written agreement. 2.

Except as expressly specified in this Agreement, Customer agrees not to do any of the following, notwithstanding the fair use doctrine or any statutory or common law provision that might otherwise permit any of the following (except to the extent applicable law makes any of the following prohibitions unenforceable or otherwise permits the recited acts notwithstanding the agreement not to perform them): (a) copy (except in the course of loading or installing) or modify the Software, including but not limited to adding new features or otherwise making adaptations that alter the functioning of the Software; (b) transfer, sublicense, lease, lend, rent or otherwise distribute the Software to any third party; (c) make the functionality of the Software available to multiple users through any means except as expressly provided herein, including but not limited to by uploading the Software to a network or file-sharing service; or (d) use the Software for purposes of competitive analysis of the Software, the development of a competing software product or service or any other purpose that is to A10 Networks’ commercial disadvantage. 3. Trade Secrets. Customer acknowledges and agrees that portions of the Software, including but not limited to the source code and the specific design and structure of individual modules or programs, constitute or contain trade secrets of A10 Networks and its licensors. Accordingly, Customer agrees not to disassemble, decompile or reverse engineer the Software, in whole or in part, or permit or authorize a third party to do so, except to the extent such activities are expressly permitted by law notwithstanding this prohibition. Further, Customer agrees not to publicly display or disclose to third parties the Software, or any portions thereof, including, but not limited to performance metrics. 4. Ownership. The copy of the Software is licensed, not sold. Customer owns the media on which the Software is recorded, but A10 Networks retains ownership of the copy of the Software itself, including all intellectual property rights therein.

A10 Networks may, at its option, require return of the Software as a condition to the remedy. In no event does A10 Networks warrant that the Software is error free or that Customer will be able to operate the Software without problems or interruptions. A10 Networks does not warrant that the Software will meet Customer requirements, that the Software will operate in the combinations that Customer may select for Execution, that the operation of the Software will be error-free or uninterrupted, or that all Software errors will be corrected.

All notices or approvals will be sent to the addresses set forth in the applicable ordering document or invoice or to such other address as may be specified by either party to the other in accordance with this section.
