and their licensors or suppliers.
7. Confidentiality.  
As used in this Agreement, "Confidential Information" means any and all information and material 
that:  (i) gives of Tenable some competitive business advantage or the opportunity of obtaining 
such advantage or is otherwise confidential or a trade secret; (ii) is marked "Confidential," 
"Restricted," or "Confidential Information" or other similar marking; (iii) is known by You to be

Tenable, is made known to You without restrictions by a third party having the right to do so; (c) 
is or becomes publicly known without violation of this Agreement; or (d) is independently developed

cooperate with and assist Tenable in every reasonable way to stop or minimize such unauthorized use 
or disclosure.  You agree that if a court of competent jurisdiction determines that You have 
breached, or attempted or threatened to breach, Your confidentiality obligations to Tenable or 
Tenable's proprietary rights, money damages, Tenable will suffer irreparable harm and that monetary 
damages will be inadequate to compensate Tenable for such breach.  Accordingly, Tenable, in 
addition to and not in lieu of any other rights, remedies or damages available to it at law or in 
equity, shall be entitled to seek appropriate injunctive relief and other measures restraining 
further attempted or threatened breaches of such obligations without requirement to post any bond. 
8. Warranty and Disclaimer.  
(a) Software.  Tenable warrants that, for a period of thirty (30) days from the Effective Date (the 
"Warranty Period"), the unmodified Software will, under normal use, substantially perform the 
functions described in its technical documentation.  If there has been a breach of this warranty, 
then Tenable's sole obligation, and Your exclusive remedy, will be for Tenable, at its option, to 
correct the performance of the Software at no charge so that it substantially performs the 
functions described in its technical documentation or to replace the Software.  You acknowledge 
that, because the license for the Software is at no charge, the remedies described in the preceding 
sentence are sufficient and can not fail of their essential purpose.  
(b) Disclaimer.  EXCEPT AS SPECIFICALLY SET FORTH IN  SECTION 8(a), TENABLE DOES NOT MAKE  ANY 
WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING ANY WARRANTIES OF TITLE, 
NON-INFRINGEMENT, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, INTEGRATION, PERFORMANCE AND 
ACCURACY, AND ANY IMPLIED WARRANTIES ARISING FROM STATUTE, COURSE OF DEALING, COURSE OF PERFORMANCE 
OR USAGE OF TRADE, OTHER THAN THOSE WARRANTIES WHICH ARE IMPLIED BY AND INCAPABLE OF EXCLUSION, 
RESTRICTION, OR MODIFICATION UNDER APPLICABLE LAW.  TENABLE MAKES NO WARRANTY THAT THE SOFTWARE 
WILL OPERATE ERROR-FREE, FREE OF ANY SECURITY DEFECTS OR IN AN UNINTERRUPTED MANNER. 
9. Exclusion Damages. 
UNDER NO CIRCUMSTANCES WILL TENABLE BE LIABLE TO YOU OR ANY OTHER PERSON OR ENTITY FOR DIRECT 
(INCLUDING FOR NEGLIGENCE, STRICT LIABILITY, BREACH OF CONTRACT, MISREPRESENTATION AND OTHER 
CONTRACT OR TORT CLAIMS), INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY OR PUNITIVE 
DAMAGES (INCLUDING NEGLIGENCE, STRICT LIABILITY, BREACH OF CONTRACT, MISREPRESENTATION AND OTHER 
CONTRACT OR TORT CLAIMS; LOST PROFITS; OR ANY DAMAGES RESULTING FROM LOSS OF DATA, SECURITY BREACH, 
PROPERTY DAMAGE, LOSS OF REVENUE, LOSS OF BUSINESS OR LOST SAVINGS), ARISING OUT OF OR IN

OF ANY OUTPUT FROM THE SOFTWARE, AND FOR ANY RELIANCE THEREON. 
10. Additional Provisions Regarding Liability.  
The parties agree that the foregoing limitations will not be read so as to limit any liability to 
an extent that would not be permitted under applicable law and specifically will not limit any 
liability for gross negligence, intentional tortious or unlawful conduct or damages for strict 
liability that may not be limited by law.
11. Indemnification.  
Each of the parties acknowledges and agrees that by entering into and performing its obligations 
under this Agreement, Tenable will not assume and should not be exposed to the business and 
operational risks associated with Your business.  You acknowledge that Your use of the Software is 
only a portion of Your overall security solution and that Tenable is not responsible for Your 
overall security solution.  As between You and Tenable, You are (and Tenable is not) responsible 
for the success or failure of such security solution.  Accordingly, You agree that you will, at 
your expense, indemnify, defend and hold Tenable harmless in all claims and actions that seek 
compensation of any kind for injury or death to persons and/or for damage to property, and that 
arise out of or relate to Your security solutions or Your use of the Software  or the solutions You 
provide to a third party through Your use of the Software.  You also agree to pay all settlements, 
costs, damages, legal fees and expenses finally awarded in all such claims and actions.

agree to perform your obligations in a manner that complies with all applicable national, regional 
and local laws, statutes, ordinances, regulations, codes and other types of government authority 
(including those governing export control, unfair competition, anti-discrimination, false 
advertising, privacy and data protection, and publicity and those identifying and procuring 
required permits, licenses, approvals, and other consents) ("Laws").  If a charge is made that You 
are not complying with any such Laws, You will promptly notify Tenable of such charges in writing.  
Without limiting the foregoing, You agree to comply with all U.S. export Laws and applicable export 
Laws of Your locality (if You are not in the United States), to ensure that no information or 
technical data provided pursuant to this Agreement is exported or re-exported directly or 
indirectly in violation of Law or without first obtaining all required authorizations or licenses.  
You will, at Your sole cost and expense, obtain and maintain in effect all permits, licenses, 
approvals and other consents related to Your obligations under this Agreement.  You agree, at Your 
expense, to comply with all foreign exchange and other Laws applicable to You.  The Software is 
licensed subject to Tenable's standard commercial agreement; Software licensed for use by the 
United States government is provided with "Restricted Rights" only as defined in 48 C.F.R.

13. Termination.
(a) You may terminate this Agreement at any time by destroying or returning to Tenable the 
Software, together with all copies, modifications and merged portions of the Software in any form.
(b) This Agreement and Your License to use the Software shall terminate automatically if You fail 
to comply with any term or condition of this Agreement. Immediately after termination of this 
Agreement, You shall destroy or return to Tenable the Software, together with all copies,

regard to choice-of-law rules or principles.  You expressly agree with Tenable that this Agreement 
shall not be governed by the U.N. Convention on Contracts for the International Sale of Goods, the 
application of which is expressly excluded. 
15. Dispute Resolution.  
You and Tenable submit to the exclusive jurisdiction of the courts of Howard County, Maryland and 
the United States District Court for Maryland, Baltimore Division, for any question or dispute 
arising out of or relating to this Agreement.  Due to the high costs and time involved in 
commercial litigation before a jury, the parties waive all right to a jury trial with respect to 
any and all issues in any action or proceeding arising out of or related to this Agreement.

Any notices or other communication required or permitted to be made or given by either Party

subject matter of this Agreement. No supplement, modification or amendment of this Agreement shall 
be binding, unless executed in writing by a duly authorized representative of each party to this 
Agreement.  The provisions of this Agreement will be deemed severable, and the unenforceability of 
any one or more provisions will not affect the enforceability of any other provisions.  In 
addition, if any provision of this Agreement, for any reason, is declared to be unenforceable, the 
parties will substitute an enforceable provision that, to the maximum extent possible under 
applicable law, preserves the original intentions and economic positions of the parties.  No 
failure or delay by a party in exercising any right, power or remedy will operate as a waiver of 
that right, power or remedy, and no waiver will be effective unless it is in writing and signed by 
the waiving party.  If a party waives any right, power or remedy, the waiver will not waive any 
successive or other right, power or remedy the party may have under this Agreement.  Any provision 
of this Agreement that imposes or contemplates continuing obligations on a party will survive the 
expiration or termination of this Agreement.  "Including" and its derivatives (such as "include" 
and "includes") mean including without limitation; this term is as defined, whether or not 
capitalized in this Agreement.

use or disclosure.  You agree that if a court of competent jurisdiction determines that You have 
breached, or attempted or threatened to breach, Your confidentiality obligations to Tenable or 
Tenable's proprietary rights, money damages, Tenable will suffer irreparable harm and that monetary 
damages will be inadequate to compensate Tenable for such breach.  Accordingly, Tenable, in 
addition to and not in lieu of any other rights, remedies or damages available to it at law or in 
equity, shall be entitled to seek appropriate injunctive relief and other measures restraining 
further attempted or threatened breaches of such obligations without requirement to post any bond.

actions that seek compensation of any kind for injury or death to persons and/or for damage to 
property, and that arise out of or relate to Your security solutions or Your use of the Plugins and 
Subscriptions, or the solutions You provide to a third party through Your use of the Plugins and 
Subscriptions.  You also agree to pay all settlements, costs, damages, legal fees and expenses 
finally awarded in all such claims and actions.

value added taxes, landing fees, import duties and the like), however designated and whether 
foreign or domestic, arising out of this Agreement, imposed on the Plugins or the use thereof, or 
Tenable's performance under this Agreement.  You agree to pay Tenable's invoices without deducting 
any present or future taxes, withholdings or other charges except those deductions it is legally

the payments made under this Agreement.  Notwithstanding the foregoing, Tenable will be solely 
responsible for its income tax obligations and all employer reporting and payment obligations with 
respect to its personnel.  You agree to pay any interest and penalties imposed by any taxing 
authorities to the extent such interest and penalties are applicable to taxes not paid at Your

tax, You will obtain such certificate or document.

amendment of this Subscription Agreement shall be binding, unless executed in writing by a duly 
authorized representative of each party to this Subscription Agreement.  The provisions of this 
Subscription Agreement will be deemed severable, and the unenforceability of any one or more 
provisions will not affect the enforceability of any other provisions.  In addition, if any 
provision of this Subscription Agreement, for any reason, is declared to be unenforceable, the 
parties will substitute an enforceable provision that, to the maximum extent possible under 
applicable law, preserves the original intentions and economic positions of the parties.  No 
failure or delay by a party in exercising any right, power or remedy will operate as a waiver of 
that right, power or remedy, and no waiver will be effective unless it is in writing and signed by 
the waiving party.  If a party waives any right, power or remedy, the waiver will not waive any 
successive or other right, power or remedy the party may have under this Subscription Agreement.  
Any provision of this Subscription Agreement that imposes or contemplates continuing obligations on 
a party will survive the expiration or termination of this Subscription Agreement.  "Including" and 
its derivatives (such as "include" and "includes") mean including without limitation; this term is 
as defined, whether or not capitalized in this Subscription Agreement.
