 13. Indemnity. 

13.1 (a) Subject to the provisions of Section 13.2 below, if a third party asserts one or more claims against TradeBlock
that (i) Company’s intellectual property (including, without limitation, Applications and data) or content provided to TradeBlock infringes such third party’s US patent issued as of the Effective Date, US copyright or trademark or
other third party intellectual property right, or (ii) arise out of or result from Company’s breach of its obligations set forth hereunder, then in each case Company will defend and pay all costs of defense of such claim (including
reasonable attorneys’ fees), and will indemnify and hold TradeBlock harmless from and against any settlement amounts agreed to by Company or damages finally awarded by a court of competent jurisdiction to such third party (except to the extent
of Tradeblock’s fraud, gross negligence or willful misconduct). (b) Subject to the provisions of Section 13.2 below, if a third party asserts one or more claims against Company that (i) TradeBlock’s Intellectual Property
(including, without limitation, Applications and data) or content provided to Company infringes such third party’s US patent issued as of the Effective Date, US copyright or trademark or other third party intellectual property right, or
(ii) arise out of or result from TradeBlock’s breach of its obligations set forth hereunder, then in each case TradeBlock will defend and pay all costs of defense of such claim (including reasonable attorneys’ fees), and will
indemnify and hold Company harmless from and against any settlement amounts agreed to by TradeBlock or damages finally awarded by a court of competent jurisdiction to such third party (except to the extent of Company’s fraud, gross negligence
or willful misconduct). 
 13.2 Procedure. With respect to the indemnification obligations hereunder, the indemnified party
should (a) give the indemnifying party prompt written notice of any claim, action, suit or proceeding; (b) granting sole control of the defense and settlement to the indemnifying party; and (c) reasonably cooperate with indemnifying
party at the indemnifying party’s expense. The indemnified party may participate in the defense of the claim at its own expense and in a manner not disruptive to indemnifying party’s conduct of the defense.
Non-compliance with this procedure does not constitute a waiver of the indemnification obligations set forth hereunder. 

14. Force Majeure. The parties shall not be liable to each other or any other person for any delay or failure in the performance of this
Agreement or for loss or damage of any nature whatsoever suffered by such party due to acts of war, acts of terrorism, acts of vandalism, lightning, fire, strike, unavailability of energy sources or any other causes beyond the party’s
reasonable control. 


 15. Product Upgrades. During the Term of this Agreement, all patches, fixes, standard new
releases and new versions of the Services made available by TradeBlock to its customers generally during the Term (collectively, “Standard Upgrades”) will be provided to Company at no additional charge.

16. Compliance with Laws. Company shall ensure that its implementation and use of the Services complies with all laws and
regulations applicable to Company’s business and geographic locations, and shall inform TradeBlock if such compliance requires any modification to TradeBlock’s standard Services offerings. Upon Company’s request, TradeBlock cannot
guarantee but will endeavor to support Company’s specific requirements for compliance with Applicable Laws and regulations, and any modification to TradeBlock’s standard Services offerings requested or required by Company may require
professional services work by TradeBlock and/or additional fees. 
 17. Third Party Applications. From time to
time, third parties may make available plug in or add-on online applications that integrate or interoperate with TradeBlock’s Services (“Applications”). If Company, in its sole discretion,
chooses to install, access or enable an Application, Company agrees that the third party Application provider may acquire access to Company’s account data and information as required for the interoperation or integration of such Application.
Accordingly, such Applications are governed by their own terms and conditions and are not considered Services under this Agreement. Company assumes full responsibility for any damages, losses, costs, or harms arising from the use of or inability to
use such Applications. To the extent permitted by law, TradeBlock disclaims all liabilities with respect to Company’s use of or inability to use such Applications and the performance or non-performance of
such Applications (including direct, indirect, incidental, punitive or consequential damages). TradeBlock has no obligation to monitor such Applications and does not control or endorse the content, messages or information found in such Applications
and specifically disclaims any liability with regard to such content, messages or information. TradeBlock does not monitor or control such Applications limitation, suspension or termination of their services and specifically disclaims any liability
with regard to such Applications service limitation, suspension or

any successor to its business. If any provision of this Agreement is held to be invalid or unenforceable, the remaining provisions of this Agreement will remain in full force and the unenforceable provision shall be interpreted so as to render it

Association under its Commercial Arbitration Rules, or such other applicable arbitration body as required by law or regulation, and judgment upon the award rendered by the arbitrators may be entered in any court having jurisdiction. Each party
expressly waives its right to a trial by jury. The application of the UN Convention on Contracts for International Sale of Goods is expressly excluded. This Agreement should not be construed in favor of or against any party by reason of the extent
to which any party or its professional advisors participated in the preparation or drafting of this Agreement. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall
constitute one and the same Agreement. The counterparts of this Agreement and all ancillary documents may be executed and delivered by facsimile or other emailed electronic signature and the receiving party may rely on the receipt of such document
by such means as if the original had been received. The headings in this Agreement are for purposes of reference only and shall not limit or otherwise affect the meaning hereof. Sections 2 (to the extent of any fees due and owing at the time of
termination), 6 through 13, 18 & 20 shall survive the termination of this Agreement.

 TradeBlock’s Licensed Indexes are each a US Dollar-denominated composite reference rate for the price of
the Digital Asset listed opposite such Licensed Index’s name in the table above, accessible via https://tradeblock.com and an application programming interface (“API”). Data inputs for the Licensed Indexes may include trades from
exchanges, over-the-counter markets, or derivative platforms. Inclusion of data from each trading venue is guided by criteria such as depth of liquidity, regulatory
compliance, data availability, acceptance of US Dollar deposits, and the discretion of TradeBlock analysts. To calculate the reference rate, trade data is cleansed and compiled in such a manner as to algorithmically reduce the impact of
anomalistic or manipulative trading. This is accomplished by adjusting the weight of each data input based on price deviation relative to the observable set, as well as recent and long-term trading volume at each venue relative to the observable
set. To calculate volume weighted price, the weighting algorithm is applied to the price and volume of all inputs for the immediately preceding 24-hour period at 4:00:00 PM on the trade date.
