Identity Verification. You will be required to provide information to us for the purposes of identity verification before you will be able to claim and take possession of any Haku Chain cryptographic tokens (“Haku Tokens”) earned as Network Rewards (defined below) in connection with the Node Software. If we are unable to verify your identity and confirm that you are eligible to use the Node Software, you will not be permitted to use the Node Software, including to earn any Network Rewards. You agree to provide us with the information we request for purposes of identity verification and permit us to keep a record of such information. You further represent and agree that all such information is complete and accurate and that you will immediately notify the Company in the event that any information provided to the Company during this process is no longer complete or accurate.

Node Software.

Subject to the terms and conditions of this Agreement, you may use the Node Software to operate a Haku Chain node on one or more machines that you own or control. The Haku Chain is a subnet of Avalanche. Please review the Avalanche (https://www.avax.network/terms-of-use) terms and conditions carefully before using the Node Software.

Key Requirement. You must purchase a Key from the Company in order to stake Haku Tokens and earn Network Rewards (defined below). The Key is a non-transferable non-fungible token. Subject to the terms and conditions of this Agreement, the Key will upgrade your Node Software and allow you to stake Haku Tokens using a single Haku Chain node on a machine you own or control. You must purchase additional Keys to stake Haku Tokens using multiple Haku Chain nodes. You may purchase a Key at https://node.hakuchain.com. You will be required to provide information to the Company for purposes of verifying your identity and confirming that you are eligible to earn Network Rewards in order to claim and take possession of any Haku Tokens earned as Network Rewards.

Connecting a Digital Wallet. In order to operate a node using the Node Software, you will need to connect a compatible third-party Ethereum blockchain digital wallet (“Wallet”). You are solely responsible for maintaining the security of your Wallet, including any associated credentials, private key, and seed phrase. The Company does not offer Wallet software or custody Haku Tokens (or any other crypto assets) on behalf of Node Software users. Your use of a third-party Wallet is subject to separate terms and conditions established by the Wallet provider.

Network Rewards; Slashing. You may receive units of Haku Tokens from the Haku Chain as a reward for contributing to the security of the Haku Chain (“Network Rewards”). All such Network Rewards are programmatically distributed to node operators by the Haku Chain. Haku Tokens will accrue on the Avalanche C-Chain network and can be “bridged” or transferred to the Haku Chain through a Haku Chain bridge for use on the Haku Chain. Additionally, some or all of your staked Haku Tokens may be programmatically destroyed as a penalty imposed by the Haku Chain (a “Slashing Penalty”) in certain instances. Please refer to the Haku Chain documentation for more details. The Company is not responsible or liable for any Network Rewards or Slashing Penalties that result from your use of the Node Software. The Company shall not be liable for any acts or omissions by you in connection with your Wallet or as a result of any cyber incident or security vulnerability that impacts your Wallet. You will be required to provide information to the Company for purposes of verifying your identity and confirming that you are eligible to earn Network Rewards before you will be permitted to claim and take possession of any Haku Tokens earned as Network Rewards.

Expiration of Network Rewards. Network Rewards can be claimed at any time prior to expiration. You will have [] days from the date that you earn a Network Reward to claim the Haku Tokens earned as part of the Network Reward before the Network Reward expires. You will be required to provide information to the Company for purposes of verifying your identity and confirming your eligibility to earn Network Rewards before you will be permitted to claim and take possession of any Haku Tokens earned as Network Rewards.

Node Software Updates. The Node Software may automatically download or prompt you to download and install updates onto your machine from time to time. By accessing or using the Node Software, you agree that the Company may download and install automatic Node Software updates onto your machine. You may opt out of automatic updates by adjusting your Node Software settings.

Disclaimer of Warranties; Limitation of Liability.

EXCEPT AS EXPRESSLY SET FORTH HEREIN, THE NODE SOFTWARE AND HAKU CHAIN ARE ISSUED ON AN “AS-IS” AND “AS AVAILABLE” BASIS AND THE COMPANY DOES NOT MAKE ANY WARRANTIES WITH RESPECT TO SUCH “AS-IS” AND “AS AVAILABLE” BASIS OR OTHERWISE IN CONNECTION WITH THIS AGREEMENT (EXCEPT AS EXPRESSLY PROVIDED HEREIN) AND THE COMPANY HEREBY DISCLAIMS ANY AND ALL EXPRESS, IMPLIED OR STATUTORY WARRANTIES AND CONDITIONS, INCLUDING ANY WARRANTIES OR CONDITIONS OF NON-INFRINGEMENT, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AVAILABILITY, ERROR-FREE OR UNINTERRUPTED OPERATION, AND ANY WARRANTIES ARISING FROM A COURSE OF DEALING, COURSE OF PERFORMANCE OR USAGE OF TRADE. TO THE EXTENT THAT THE COMPANY MAY NOT, AS A MATTER OF APPLICABLE LAW, DISCLAIM ANY IMPLIED WARRANTY OR CONDITION, THE SCOPE AND DURATION OF SUCH WARRANTY OR CONDITION SHALL BE APPLIED TO THE MINIMUM EXTENT PERMITTED UNDER SUCH APPLICABLE LAW.

IN NO EVENT SHALL THE COMPANY BE LIABLE TO YOU FOR ANY CONSEQUENTIAL, INDIRECT, INCIDENTAL, OR SPECIAL DAMAGES OF ANY TYPE OR NATURE HOWEVER ARISING, INCLUDING, WITHOUT LIMITATION, EXEMPLARY OR PUNITIVE DAMAGES, LOST PROFITS OR REVENUES, OR DIMINUTION IN VALUE, ARISING OUT OF OR RELATING TO THE NODE SOFTWARE OR THE HAKU CHAIN NETWORK, WHETHER OR NOT THE POSSIBILITY OF SUCH DAMAGES HAS BEEN DISCLOSED TO OR COULD HAVE BEEN REASONABLY FORESEEN BY YOU, REGARDLESS OF THE LEGAL OR EQUITABLE THEORY (CONTRACT, TORT, OR OTHERWISE) UPON WHICH THE CLAIM IS BASED. IN ADDITION, UNDER NO CIRCUMSTANCES SHALL THE COMPANY'S AGGREGATE LIABILITY UNDER THE AGREEMENT EXCEED ONE-HUNDRED U.S. DOLLARS ($100.00).

SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES OR THE LIMITATION OR EXCLUSION OF LIABILITY FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES. ACCORDINGLY, SOME OF THE LIMITATIONS SET FORTH ABOVE MAY NOT APPLY TO YOU. IF YOU ARE DISSATISFIED WITH THE NODE SOFTWARE, YOUR SOLE AND EXCLUSIVE REMEDY IS TO DISCONTINUE USING THE NODE SOFTWARE.

Indemnification.

You agree, at your own expense, to indemnify, defend, and hold harmless the Company and its partners and affiliates and their respective owners, members, agents, directors, officers, employees, representatives, affiliates, successors, and assigns against any claim, suit, action, or other proceeding from and against any and all claims, damages, liabilities, costs, and expenses, including reasonable attorneys’ and experts’ fees, arising out of or in connection with your breach of the Agreement, your violation of any law or regulation, or your use of the Node Software. You agree to pay any and all costs, damages, and expenses, including but not limited to reasonable attorneys’ fees and costs awarded against or otherwise incurred by or in connection with or arising from any such claim, suit, action, or proceeding attributable to any such claim. The Company reserves the right, at its own expense, to assume the exclusive defense and control of any matter otherwise subject to indemnification by you, in which event you will fully cooperate with the Company in asserting any available defense.

If you have a dispute with one or more users of the Node Software or other third parties, you release the Company (and its affiliates and service providers, and each of their officers, directors, agents, joint ventures, employees, and representatives) from all claims, demands, and damages (actual and consequential) of every kind and nature arising out of or in any way connected with such disputes.

Dispute Resolution; Agreement to Arbitrate.

All disputes, claims and controversies, whether based on past, present or future events, arising out of or relating to statutory or common law claims, the breach, termination, enforcement, interpretation or validity of any provision of the Agreement, and the determination of the scope or applicability of your agreement to arbitrate any dispute, claim or controversy originating from the Agreement, will be determined by binding arbitration in Tortola, the British Virgin Islands pursuant to the BVI IAC Arbitration Rules, before a single arbitrator.

The arbitrator will apply the substantive law of the British Virgin Islands, excluding its conflict or choice of law rules.

Nothing in the Agreement will preclude the parties from seeking provisional remedies in aid of arbitration from a court of appropriate jurisdiction.

A party must notify the other party of its intent to commence arbitration prior to commencing arbitration. The notice must specify the date on which the arbitration demand is intended to be filed, which must be at least thirty (30) days after the date of the notice. During this time period, the parties will meet for the purpose of resolving the dispute prior to commencing arbitration.

Subject to Section 8.4, each party may commence arbitration by providing to the BVI International Arbitration Centre and the other party to the dispute a written demand for arbitration, stating the subject of the dispute and the relief requested.

Subject to the disclaimers and limitations of liability stated in the Agreement, the appointed arbitrators may award monetary damages and any other remedies allowed by the laws of the British Virgin Islands (including the BVI IAC Arbitration Rules). In making a determination, the arbitrator will not have the authority to modify any term of the Agreement. The arbitrator will deliver a reasoned, written decision with respect to the dispute to each party, who will promptly act in accordance with the arbitrator’s decision. Any award (including interim or final remedies) may be confirmed in or enforced by a state or federal court located in the British Virgin Islands. The decision of the arbitrator will be final and binding on the parties, and will not be subject to appeal or review.

The party initiating the arbitration is responsible for paying the applicable filing fee. Each party will advance one-half of the fees and expenses of the arbitrator, the costs of the attendance of the arbitration reporter at the arbitration hearing and the costs of the arbitration facility. In any arbitration arising out of or relating to the Agreement, the arbitrator will award to the prevailing party, if any, the costs and attorneys’ fees reasonably incurred by the prevailing party in connection with those aspects of its claims or defenses on which it prevails, and any opposing awards of costs and legal fees awards will be offset.

The parties will keep confidential the existence of the arbitration, the arbitration proceeding, the hearing and the arbitrator’s decision, except (a) as necessary to prepare for and conduct the arbitration hearing on the merits; (b) in connection with a court application for a preliminary remedy, or confirmation of an arbitrator’s decision or its enforcement; (c) the Company may disclose the arbitrator’s decision in confidential settlement negotiations; (d) each party may disclose as necessary to professional advisors that are subject to a strict duty of confidentiality; and (e) as applicable law otherwise requires. The parties, witnesses and arbitrator will treat as confidential and will not disclose to any third person (other than witnesses or experts) any documentary or other evidence produced in any arbitration, except as applicable so requires or if the evidence was obtained from the public domain or was otherwise obtained independently from the arbitration.

In the case of a conflict between the provisions of this Section 8 and the BVI IAC Arbitration Rules, the provisions of this Section 8 shall prevail.

To the extent permitted by applicable law, any dispute arising out of or relating to the Agreement, whether in arbitration or in court, shall be conducted only on an individual basis and not in a className, consolidated or representative action. Notwithstanding any other provision of the Agreement or the BVI IAC Arbitration Rules, disputes regarding the interpretation, applicability or enforceability of this className waiver may be resolved only by a court and not by an arbitrator. If this waiver of className or consolidated actions is deemed invalid or unenforceable, neither party is entitled to arbitration.

If for any reason a claim or dispute proceeds in court rather than through arbitration, each party knowingly and irrevocably waives any right to trial by jury in any action, proceeding or counterclaim arising out of or relating to the Agreement.

Term; Termination.

The Agreement is effective beginning when you accept the Agreement or first access or use the Node Software and ending when terminated as set forth in Section 9.2.

Your right to use and access the Node Software will automatically terminate in the event you fail to comply with any of the terms and conditions of the Agreement. Termination will be effective without notice.

Upon termination of the Agreement, you must immediately cease all use of the Node Software and destroy all copies, full or partial, of the Node Software. Sections 4, 5, 6, 7, 8, 9 and 10 of this Agreement shall survive any such termination.

Waivers. For a waiver to be deemed effective, a waiver must be in a writing signed by the waiving party. The failure of either party to enforce any provision of the Agreement will not constitute a waiver of that party’s rights to subsequently enforce the provision.

Cumulative Rights; Injunctions. The rights and remedies of the parties under the Agreement are cumulative, and each party may exercise any of its rights and enforce any of its remedies under the Agreement, along with all other rights and remedies available to it at law, in equity or otherwise. Any material breach by a party of the Agreement could cause the non-breaching party irreparable harm for which the non-breaching party has no adequate remedies at law. Accordingly, the non-breaching party is entitled to seek specific performance or injunctive relief for any such breach.

Severability. If any provision of these the Agreement is declared to be invalid, illegal or unenforceable by a court of competent jurisdiction, then the validity, legality and enforceability of the remaining provisions contained herein shall not be affected thereby and the remainder of the provisions of the Agreement shall remain valid, legal and enforceable to the fullest extent permitted by law.

Governing Law. The Agreement shall be solely and exclusively governed, construed and enforced in accordance with the laws of the British Virgin Islands without giving effect to conflict of law rules or principles that would cause the application of the laws of any other jurisdiction.

Entire Agreement. The Agreement constitutes the entire agreement and understanding between you and the Company, and supersedes all previous communications, representations or agreements, whether written or oral, with respect to the subject matter hereof.

No Third-Party Beneficiaries. The Agreement is not intended and shall not be construed to create any rights or remedies in any parties other than you and the Company and other Company affiliates, which each shall be a third-party beneficiary of the Agreement, and no other person shall assert any rights as a third-party beneficiary hereunder.
