The Participant understands that Wilson, Sonsini, Goodrich & Rosati, P.C. acts as counsel only to the Company and does not represent the Participant or any other person by reason of any receipt of the Tokens.

The Participant is participating in the Program without being furnished any offering literature other than the Participation Information, and is making this participation decision solely in reliance upon the information contained in the Participation Information and upon any investigation made by the Participant or Participant’s advisers, but not on any recommendation to participate in the Program in order to obtain the opportunity to receive the Tokens by any Blockstack Party.

6.6.3. The Participant hereby agrees to immediately notify the Company if the Participant knows, or has reason to suspect, that any of the representations in this Section 6.6.3 have become incorrect or if there is any change in the information affecting these representations and covenants.

6.6.4. The Participant agrees that, if at any time it is discovered that any of the foregoing anti-money laundering representations are incorrect, or if otherwise required by applicable laws or regulations, the Company may undertake appropriate actions, and the Participant agrees to cooperate with such actions, to ensure compliance with such laws or regulations.

6.6.5. The Participant acknowledges and agrees that the Company, in complying with anti-money laundering statutes, regulations and goals, may file any information with governmental and law enforcement agencies to identify transactions and activities that the Company or any other Blockstack Party or their agents reasonably determines to be suspicious, or as otherwise required by law.

6.7. The Participant understands that no Blockstack Party is registered with the SEC or with the securities commission of any state or other jurisdiction as a broker-dealer under the Exchange Act. The Participant will not be afforded the full set of protections provided under the Exchange Act or comparable state law.

6.8. The Participant understands and agrees that if the Company were deemed to be a money transmitter or money services business, it would be subject to significant additional regulation that could lead to significant changes with respect to the Network, how the Tokens are structured, how they are purchased and sold, and other issues, and would greatly increase the Company’s costs in creating and facilitating transactions in the Tokens. It could lead to the termination of the Tokens. Further, a regulator could take action against the Company and Blockstack Parties if it views the Tokens and the Network as a violation of existing law. Any of these outcomes would negatively affect the value of the Tokens and/or could cause the Company to cease operations.

(8) “Close Associate of a Senior Foreign Political Figure” shall mean a person who is widely and publicly known internationally to maintain an unusually close relationship with the Senior Foreign Political Figure, and includes a person who is in a position to conduct substantial domestic and international financial transactions on behalf of the Senior Foreign Political Figure.

(9) “Non-Cooperative Jurisdiction” shall mean any foreign country that has been designated as non-cooperative with international anti-money laundering principles or procedures by an intergovernmental group or organization, such as the Financial Action Task Force, of which the U.S. is a member and with which designation the U.S. representative to the group or organization continues to concur.

6.9. Virtual Currency Business Matters:

6.9.1. The Participant understands and agrees that the Company does not intend to operate in any state that requires the Company to obtain an applicable license to conduct a virtual currency business, and that if a Participant is a resident of a state that requires the Company to obtain an applicable license to conduct a virtual currency business, this Agreement is void and all rights and privileges of the Participant under this Agreement are canceled. If a Participant is a resident of a state that requires the Company to obtain a license to conduct a virtual currency business, the Company will not allow the Participant to receive the Tokens and participate on the Network. Further, any prohibited Token transaction inconsistent with this Section 6.9.1 may be unable to be rescinded.

6.9.2. The Participant understands and agrees that if the Company and the Blockstack Parties were deemed to be conducting an unlicensed virtual currency business they would be subject to significant additional regulation and/or regulatory consequences, which could lead to significant changes with respect to the Network, how the Tokens are structured, how they are purchased and sold, and other issues, and would greatly increase the Company’s costs in creating and facilitating transactions in the Tokens. Further, a regulator could take action against the Company and the Blockstack Parties if it views the Tokens and the Network as a violation of existing law. Any of these outcomes would negatively affect the value of the Tokens and/or could cause the Company to cease operations. Participants are strongly encouraged to seek independent legal advice regarding their individual circumstances in determining whether they are eligible to acquire the Tokens.

[6.10. The Participant understands and agrees that the regulatory risks described in this Section 7 take into consideration U.S. law only and are a brief summary of the risks associated with the participation in the Program for and the Tokens, which are more fully described in the Offering Circular.

6.11. The Participant further understands and agrees that it is anticipated that the Tokens will also be sold or resold outside the United States, which could subject the Blockstack Parties or the Tokens to non-U.S. legal requirements, which could be significant. Non-U.S. regulation could lead to the same types of changes and outcomes described above with respect to U.S. regulation, and any of these outcomes would negatively affect the value of the Tokens and/or cause the Blockstack Parties to cease operations.](10)

The Participant understands and agrees that in connection with the services provided by the Company, its personal data may be transferred and/or stored in various jurisdictions in which the Blockstack Parties have a presence, including in or to jurisdictions that may not offer a level of personal data protection equivalent to the Participant’s country of residence.

The Participant understands that, to the fullest extent permitted by law, any notices, disclosures, forms, privacy statements, reports or other communications (collectively, “Communications”) regarding the Company, the Participant’s participation in the Program for Tokens (including annual and other updates and tax documents) may be delivered by electronic means, such as by e-mail. The Participant hereby consents to electronic delivery as described in the preceding sentence.

TO THE FULLEST EXTENT PERMITTED BY LAW, IN NO EVENT WILL THE APP.CO ENTITIES BE LIABLE TO YOU FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES (INCLUDING DAMAGES FOR LOSS OF PROFITS, GOODWILL, OR ANY OTHER INTANGIBLE LOSS) ARISING OUT OF OR RELATING TO YOUR ACCESS TO OR USE OF, OR YOUR INABILITY TO ACCESS OR USE, THE SERVICE, THE DAPPS, OR ANY MATERIALS OR CONTENT ON THE SERVICE, OR THE APP MINING PROGRAM, WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), STATUTE, OR ANY OTHER LEGAL THEORY, AND WHETHER OR NOT ANY APP.CO ENTITY HAS BEEN INFORMED OF THE POSSIBILITY OF DAMAGE.

EXCEPT AS PROVIDED IN SECTION 14.4 AND TO THE FULLEST EXTENT PERMITTED BY LAW, THE AGGREGATE LIABILITY OF THE APP.CO ENTITIES TO YOU FOR ALL CLAIMS ARISING OUT OF OR RELATING TO (I) THE USE OF OR ANY INABILITY TO USE ANY PORTION OF THE SERVICE OR THE DAPPS, (II) THE APP MINING PROGRAM, OR (III) OTHERWISE UNDER THESE TERMS, WHETHER IN CONTRACT, TORT, OR OTHERWISE, IS LIMITED TO $100.

EACH PROVISION OF THESE TERMS THAT PROVIDES FOR A LIMITATION OF LIABILITY, DISCLAIMER OF WARRANTIES, OR EXCLUSION OF DAMAGES IS INTENDED TO AND DOES ALLOCATE THE RISKS BETWEEN THE PARTIES UNDER THESE TERMS. THIS ALLOCATION IS AN ESSENTIAL ELEMENT OF THE BASIS OF THE BARGAIN BETWEEN THE PARTIES. EACH OF THESE PROVISIONS IS SEVERABLE AND INDEPENDENT OF ALL OTHER PROVISIONS OF THESE TERMS. THE LIMITATIONS IN THIS SECTION 13 WILL APPLY EVEN IF ANY LIMITED REMEDY FAILS OF ITS ESSENTIAL PURPOSE.

14. Dispute Resolution and Arbitration

14.1. Generally. In the interest of resolving disputes between you and App.co in the most expedient and cost-effective manner, and except as described in Section 14.2, you and App.co agree that every dispute arising in connection with these Terms will be resolved by binding arbitration except for any disputes arising out of alleged breaches or violations of the federal and state Securities laws of the United States. Arbitration is less formal than a lawsuit in court. Arbitration uses a neutral arbitrator instead of a judge or jury, may allow for more limited discovery than in court, and can be subject to very limited review by courts. Arbitrators can award the same damages and relief that a court can award. This agreement to arbitrate disputes includes all claims arising out of or relating to any aspect of these Terms, whether based in contract, tort, statute, fraud, misrepresentation, or any other legal theory, and regardless of whether a claim arises during or after the termination of these Terms. YOU UNDERSTAND AND AGREE THAT, BY ENTERING INTO THESE TERMS, YOU AND APP.CO ARE EACH WAIVING THE RIGHT TO A TRIAL BY JURY OR TO PARTICIPATE IN A CLASS ACTION.

14.2. Exceptions. Despite the provisions of Section 14.1, nothing in these Terms will be deemed to waive, preclude, or otherwise limit the right of either party to: (a) bring an individual action in small claims court; (b) pursue an enforcement action through the applicable federal, state, or local agency if that action is available; (c) seek injunctive relief in a court of law in aid of arbitration; or (d) to file suit in a court of law to address an intellectual property infringement claim.

14.3. Arbitrator. Any arbitration between you and App.co will be settled under the Federal Arbitration Act and administered by the American Arbitration Association (“AAA”) under its Consumer Arbitration Rules (collectively, “AAA Rules”) as modified by these Terms. The AAA Rules and filing forms are available online at www.adr.org, by calling the AAA at 1-800-778-7879, or by contacting App.co. The arbitrator has exclusive authority to resolve any dispute relating to the interpretation, applicability, or enforceability of this binding arbitration agreement.

14.4. Notice of Arbitration; Process. A party who intends to seek arbitration must first send a written notice of the dispute to the other party by certified U.S. Mail or by Federal Express (signature required) or, only if that other party has not provided a current physical address, then by electronic mail (“Notice of Arbitration”). App.co’s address for Notice is: Blockstack PBC, 101 W 23rd Street, Suite 224, New York, NY 10011. The Notice of Arbitration must: (a) describe the nature and basis of the claim or dispute; and (b) set forth the specific relief sought (“Demand”). The parties will make good faith efforts to resolve the claim directly, but if the parties do not reach an agreement to do so within 30 days after the Notice of Arbitration is received, you or App.co may commence an arbitration proceeding. All arbitration proceedings between the parties will be confidential unless otherwise agreed by the parties in writing. During the arbitration, the amount of any settlement offer made by you or App.co must not be disclosed to the arbitrator until after the arbitrator makes a final decision and award, if any. If the arbitrator awards you an amount higher than the last written settlement amount offered by App.co in settlement of the dispute prior to the award, App.co will pay to you the higher of: (i) the amount awarded by the arbitrator; or (ii) $10,000.

14.5. Fees. If you commence arbitration in accordance with these Terms, App.co will reimburse you for your payment of the filing fee, unless your claim is for more than $10,000, in which case the payment of any fees will be decided by the AAA Rules. Any arbitration hearing will take place at a location to be agreed upon in New York County, New York, but if the claim is for $10,000 or less, you may choose whether the arbitration will be conducted: (a) solely on the basis of documents submitted to the arbitrator; (b) through a non-appearance based telephone hearing; or (c) by an in-person hearing as established by the AAA Rules in the county (or parish) of your billing address. If the arbitrator finds that either the substance of your claim or the relief sought in the Demand is frivolous or brought for an improper purpose (as measured by the standards set forth in Federal Rule of Civil Procedure 11(b)), then the payment of all fees will be governed by the AAA Rules. In that case, you agree to reimburse App.co for all monies previously disbursed by it that are otherwise your obligation to pay under the AAA Rules. Regardless of the manner in which the arbitration is conducted, the arbitrator must issue a reasoned written decision sufficient to explain the essential findings and conclusions on which the decision and award, if any, are based. The arbitrator may make rulings and resolve disputes as to the payment and reimbursement of fees or expenses at any time during the proceeding and upon request from either party made within 14 days of the arbitrator’s ruling on the merits.

14.6. No Class Actions. YOU AND App.co AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS OR REPRESENTATIVE PROCEEDING. Further, unless both you and App.co agree otherwise, the arbitrator may not consolidate more than one person’s claims, and may not otherwise preside over any form of a representative or class proceeding.

14.7. Modifications to this Arbitration Provision. If App.co makes any future change to this arbitration provision, other than a change to App.co’s address for Notice of Arbitration, you may reject the change by sending us written notice within 30 days of the change to App.co’s address for Notice of Arbitration, in which case your account with App.co will be immediately terminated and this arbitration provision, as in effect immediately prior to the changes you rejected will survive.

14.8. Enforceability. If Section 14.6 is found to be unenforceable or if the entirety of this Section 14 is found to be unenforceable, then the entirety of this Section 14 will be null and void and, in that case, the parties agree that the exclusive jurisdiction and venue described in Section 15.2 will govern any action arising out of or related to these Terms.

14.9 The Blockstack Parties agree and acknowledge that nothing in these Terms shall be deemed to constitute a waiver of any Blockstack Party’s compliance with the federal securities laws and the rules and regulations thereunder, nor shall it constitute a waiver by the Participant of any of the Participant’s legal rights under applicable U.S. federal securities laws or any other laws whose applicability is not permitted to be contractually waived. In addition, this Dispute Resolution and Arbitration section shall not apply to claims arising under the U.S. federal securities laws.

15. Miscellaneous

15.1. General Terms. These Terms, together with the Privacy Policy and any other agreements expressly incorporated by reference into these Terms, are the entire and exclusive understanding and agreement between you and App.co regarding your use of the Service.

Throughout these Terms the use of the word “including” means “including but not limited to”. If any part of these Terms is held to be invalid or unenforceable, the unenforceable part will be given effect to the greatest extent possible, and the remaining parts will remain in full force and effect.

15.2. Governing Law. These Terms are governed by the laws of the State of New York without regard to conflict of law principles.

App Mining Participant Terms

Your participation in App.co’s App Mining program (the “Program”) is subject to the following additional terms and conditions (the “App Mining Terms”), which are subject to, and hereby incorporated into, the App.co Terms of Service (“Terms of Service”). The Program is sponsored by Blockstack PBC, a Delaware public benefit corporation (“Blockstack”). By accepting these App Mining Terms, you agree that you have read, understood, and agree to be bound by these App Mining Terms and the Terms of Service and related policies (available at App.co) (collectively, the “Terms”) as updated from time to time, which, collectively, govern your participation in the Program and use of the Service. All capitalized terms used but not defined herein will have the meaning given to them in the Terms of Service.

BY ACCEPTING THESE TERMS, YOU ARE AGREEING THAT ALL DISPUTES WILL BE RESOLVED IN ACCORDANCE WITH SECTION 14 OF THE TERMS OF SERVICE. EXCEPT FOR CERTAIN DISPUTES DESCRIBED IN THAT SECTION 14, DISPUTES ARISING UNDER THESE TERMS WILL BE RESOLVED BY BINDING, INDIVIDUAL ARBITRATION. YOU ARE WAIVING THE RIGHT TO A TRIAL BY JURY OR TO PARTICIPATE IN ANY CLASS ACTION OR REPRESENTATIVE PROCEEDING. This provision shall not apply to claims arising under the U.S. federal securities laws.

1. Program Overview. When you submit your Blockstack-integrated application (the “App”) to the Program by submitting and registering your app at https://app.co/mining, Blockstack’s third-party app reviewers (“Reviewers”) will review and rank the App based on a combination of objective criteria and reviewer votes (as described further in Section 4), where Reviewers and eligible voters are instructed to assess the overall quality of the App and value to the Blockstack application ecosystem. Blockstack will determine voter eligibility in its sole discretion. Each month, ranked apps (the “Ranked Apps”) will each be awarded a share of the total prize pool, in proportion to each Ranked Apps’ ranking (a “Payout”).

2. Eligibility. You must be at least 18 years of age and the age of majority in your jurisdiction of residence to participate in the Program. Blockstack officers, directors, employees, agents, representatives and contractors, Reviewers, and any other individuals or entities involved in the development or administration of the Program, and immediate family members of the foregoing, are prohibited from participating (“Precluded Persons”). Final determination of eligibility shall be made by Blockstack in its sole discretion.

3. Submission of Apps. You must submit your App through the web site at https://app.co/mining prior to the end of the calendar month to be eligible to earn a Payout in that month. No payment or purchase of any kind is necessary to enter or earn a Payout; your Payout will be based on the quality of your App as indicated in these App Mining Terms. Blockstack is not responsible for any problems with your App, including any issues associated with hardware, software, telephone, Internet, virus contamination, network, human error, electronic malfunctions, or any other technical problems; or delay, failure or malfunction of any kind relating to the Program.

4. Reviewer Criteria. Reviewers will review and rank your App and the other Dapps participating in the program using the criteria to be found here [link].

5. Rules.

a. ANY ATTEMPT TO DELIBERATELY UNDERMINE THE LEGITIMATE OPERATION OF THE PROGRAM IS A VIOLATION OF CRIMINAL AND CIVIL LAWS, AND SHOULD SUCH AN ATTEMPT BE MADE, BLOCKSTACK RESERVES THE RIGHT TO SEEK DAMAGES AND PURSUE ALL OTHER REMEDIES AGAINST ANY YOU TO THE FULLEST EXTENT PERMITTED BY LAW.

b. Reviewers and other Precluded Persons are prohibited from submitting an App to the Program. If your App is participating in the program, you cannot be a Reviewer or Precluded Person.

6. Representations and Warranties. By submitting your App, you represent and warrant that:

a. You are the creator and owner of the App or are otherwise authorized to submit the App to the Program by the creator or owner of the App;

b. You are not a Precluded Person;

c. All information that you provide to us in connection with the Program is true and accurate.

7. Payouts. The total prize amounts and allocation among Ranked Apps is subject to change. Payouts will be calculated on the 17th of each calendar month, and payments will be initiated with approximately 1 day after the calculation of the Payout. If you are entitled to a Payout, then you will be notified through the Service and via the email address you provide when you submit the App. Payouts will be paid in Stacks Tokens, Bitcoin, or United States dollars, as Blockstack may decide in its sole discretion, and you must take all necessary steps to be able to receive any Payout. Receipt of Stacks Tokens is subject to your compliance with the Additional Agreement for Stacks Tokens available at [link]. The Additional Agreement for Stacks Tokens is hereby incorporated by this reference into, and made a part of, these Terms. You may not substitute your Payout for another prize, though Blockstack reserves the right to substitution something of equal or greater value. Blockstack does not guarantee that the Payout can be made available to the Ranked Apps. If a Payout is unable to be fulfilled due to any applicable law, rule, or regulation, or if a Ranked App cannot claim the Payout for any reason, Blockstack reserves the right not to award the applicable Payout. The amount of any Payouts forfeited for any reason will not be redistributed to the remaining Ranked Apps. The right to receive a Payout cannot be transferred or assigned. You are solely responsible for any federal, state, local or other applicable taxes associated with your Payout, and you may be required to provide necessary tax-related information to receive your Payout, which also could be subject to withholding.

8. Public Posting of Payouts. You acknowledge and agree that all Payout amounts may be posted on the app.co website and other public sites or forums. Such posting may include a link to a visible blockchain payment verifier, which will indicate your public Bitcoin or other token or currency address. You acknowledge that such a payment verifier or payout receipt may be used to identify your or your organization’s public Bitcoin or other token or currency’s address as well as the amount that was paid. By participating in the Program, you agree that (i) we are free to make such a public posting of all payout amounts and payment verifiers, and (ii) we have no liability or responsibility for anything directly or indirectly related to such posting, including any third party’s use of such posting to identify you or your organization.

9. Cancellation of the Program. Blockstack reserves the right at its sole discretion to suspend, cancel, modify or terminate the Program temporarily or permanently for any reason, including without limitation due to a force majeure event or technical failures, or any other causes which corrupt or affect the administration, security, fairness, integrity, or proper conduct of the Program.

10. Term and Termination. By submitting an App, you agree to these App Mining Terms. Either party may terminate these App Mining Terms and your access to the Program on notice to the other party. App.co’s sole liability to you for termination of these App Mining Terms will be payment of any Payouts that you have earned but not received.

11. General. These App Mining Terms will be governed by the laws of the State of New York, without regard to conflict of law principles. In the event of a conflict between these App Mining Terms and the Terms of Service or any other policies referenced therein, these App Mining Terms will prevail.
