COINBASE PRIME BROKER AGREEMENT

General Terms and Conditions

1. Introduction

1.1 This agreement dated as of __________________ (the “Effective Date”) (including, the Coinbase Custody Services Agreement attached hereto as Exhibit A (the “Custody Agreement”), the Coinbase Master Trading Agreement attached hereto as Exhibit B (the “MTA”), and all other exhibits, addenda, and supplements attached hereto or referenced herein, (collectively, the “Coinbase PBA”)), is entered into by and between Xxxxxx Scientific, Inc. (“Client”), and Coinbase, Inc. (“Coinbase”), for and on behalf of itself and on behalf of Coinbase Custody Trust Company, LLC (“Coinbase Custody”), and, if applicable, Coinbase Credit, Inc. (“Coinbase Credit,”) or Coinbase Custody International Ltd. (“CCI”) and collectively with Coinbase and Coinbase Custody, the “Coinbase Entities”).

1.2 This Coinbase PBA sets forth the terms and conditions pursuant to which the Coinbase Entities will provide to Client custody, trade execution, lending, post-trade credit (if applicable), and other services (collectively, the “PB Services”) for certain digital assets (“Digital Assets”) and cash as set forth herein. As part of the PB Services, Coinbase will establish and maintain for Client the Trading Account (as defined and described in Section 2 of the MTA), and Coinbase Custody will establish and maintain for Client the Vault Account (as defined and described in Sections 1.1 and 2 of the Custody Agreement) (collectively with the Trading account, the “Accounts”).

1.3 Client’s Digital Assets are referred to as “Client Digital Assets,” Client’s cash is referred to as “Client Cash,” and Client Digital Assets and Client Cash are together referred to as “Client Assets.”

1.4 Client and the Coinbase Entities (individually or collectively, as the context requires) may also be referred to as a “Party.” Capitalized terms not defined in these General Terms and Conditions (the “General Terms”) shall have the meanings assigned to them in the respective exhibit, addendum, or supplement. Any singular term in this Coinbase PBA will be deemed to include the plural, and any plural term the singular and the words “such as,” “include,” “includes,” or “including” are deemed to be followed by the words “without limitation,” whether or not expressly stated. The word “will” shall be construed to have the same meaning and effect as the word “shall.” In the event of a conflict between these General Terms and any exhibit, addendum, or supplement hereto, the document governing the specific relevant PB Service shall control in respect of such PB Service.

2. Conflicts of Interest Acknowledgement

Client acknowledges that the Coinbase Entities may have actual or potential conflicts of interest in connection with providing the PB Services including that (i) Orders (as such term is defined in the MTA) may be routed to Coinbase’s exchange platform where Orders may be executed against other Coinbase clients or with Coinbase acting as principal, (ii) the beneficial identity of the purchaser or seller with respect to an Order is unknown and therefore may be another Coinbase client, (iii) Coinbase does not engage in front-running, but is aware of Orders or imminent Orders and may execute a trade for its own inventory (or the account of an affiliate) while in possession of that knowledge, and (iv) Coinbase may act in a principal capacity with respect to certain Orders (e.g., to fill residual Order size when a portion of an Order may be below the minimum size accepted by the CTV (as defined in Section 1.1 of the MTA)). As a result of these and other conflicts, the Coinbase Entities may have an incentive to favor their own interests and the interests of their affiliates over a particular client’s (including Client’s) interests. Coinbase has in place certain policies and procedures that are designed to mitigate such conflicts.

3. Account Statements

If Client is a trust, Client agrees that the Coinbase Entities shall have no liability for following the trustee’s instructions.

4.3 Each Coinbase Entity will comply with Client’s Instructions to stake, stack, or vote Client Digital Assets to the extent the applicable Coinbase Entity supports proof of stake validation, proof of transfer validation, or voting for such Digital Assets. The Coinbase Entities may, in their sole discretion, decide whether or not to support or cease supporting staking services, stacking, or voting for a Digital Asset.

(v) The value of Digital Assets may be derived from the continued willingness of market participants to exchange any fiat currency for Digital Assets, which may result in the permanent and total loss of value of a Digital Asset should the market for that Digital Asset disappear;

(vi) There is no assurance that a person or entity who accepts a Digital Assets as payment today will continue to do so in the future;

(vii) The volatility and unpredictability of the price of Digital Assets relative to fiat currency may result in significant losses over a short period of time;

In the event of a fork, Client agrees that the Coinbase Entities may temporarily suspend PB Services (with or without notice to Client) and that the Coinbase Entities may[***] determine whether or not to support or cease supporting either branch of the forked protocol entirely. Client agrees that the Coinbase Entities shall have no liability, obligation, or responsibility whatsoever arising out of or relating to the operation of Protocols, transactions affected by Governance Modifiable Blockchains, or an unsupported branch of a forked protocol and, accordingly, Client acknowledges and assumes the risk of the same.

14.2 Except to the extent otherwise specifically communicated by the Coinbase Entities through a written public statement on the Coinbase website, the Coinbase Entities do not support airdrops, metacoins, colored coins, side chains, or other derivative, enhanced, or forked protocols, tokens, or coins, which supplement or interact with a Digital Asset (collectively, “Advanced Protocols”) in connection with the PB Services.

If Coinbase has reason to believe Client is deceased but Coinbase does not have proof of Client’s death in a form satisfactory to Coinbase, Client authorizes Coinbase to make inquiries, whether directly or through third parties, that Coinbase considers necessary to ascertain whether Client is deceased. Upon receipt by Coinbase of proof satisfactory to Coinbase that Client is deceased, the fiduciary Client designated in a valid will or similar testamentary document will be required to enter into a new Coinbase Prime Broker Agreement.

In the event Coinbase determines, in its sole and absolute discretion, that there is uncertainty regarding the validity of the fiduciary designation, Coinbase reserves the right to require an order resolving such issue from a court of competent jurisdiction before taking any action relating to the PB Services. Pursuant to the above, the entry into a new Coinbase Prime Broker Agreement by a designated fiduciary is mandatory following the death of Client, and Client hereby agrees that its fiduciary shall be required to enter into a new Coinbase Prime Broker Agreement and provide required account opening information to gain access to the contents of Client’s PB Services.
