Confidentiality. The Parties hereby agree that during the Term, the contents of this Agreement, including communications, all non-publicly available documents, and any data regarding Offering participants are strictly confidential and that neither Party shall disclose its contents to any unaffiliated third-party, except those employees, contractors, or associates who are subject to confidentiality with respect to such information, without written consent of the other Party, provided that the Issuer shall be free to disclose the fees due and payable in connection with the Offerings to its Investors therein.

This Section 10 shall survive for a period of 3 years beyond termination of this Agreement, except with respect to Confidential Information that is personally or identifying information regarding or relating to an Investor, in which case Section 10 shall be indefinite, unless in the case of Issuer, such disclosure is authorized by the relevant Investor in connection with the Securities and in the case of ODB, is otherwise permitted by Law.

Compliance with Law; Governing Law. Each Party shall comply with any Law applicable to the performance of its obligations hereunder. This Agreement shall be governed by the laws of the State of New York, except with respect to the choice of law provisions therein or to the extent inconsistent with FINRA Rules applicable to an arbitration proceeding under Section 10(f) below.

Arbitration. Any controversy or claim arising out of or relating to this Agreement shall be submitted to arbitration and conducted before FINRA Dispute Resolution before a panel of three arbitrators and in accordance with FINRA rules.

Issuer agrees that it must meet all of Republic’s confidential internal policies, as dictated by Republic’s anti-money laundering policy, know-your-consumer policy, published policies on the Republic Platform and other applicable regulations (collectively, the “Republic Policies”). ODB reserves the right to control the timing of the Offerings and delay, cancel or withdraw an Offering at any time for the following reasons: (i) pursuant to its due diligence and suitability obligations, (ii) in the interest of investor protection, or (iii) to protect ODB’s reputation.

No Agency. Neither Party is an agent, representative, or partner of the other, and cannot bind or obligate the other. This Agreement does not create a joint venture, partnership, or association between the Parties.

Assignment. The Issuer cannot assign, sublicense, or transfer this Agreement or any related rights without ODB’s prior written consent, which may be withheld at ODB’s discretion. ODB can assign, sublicense, or transfer this Agreement or any related rights to any of its affiliates authorized to provide the Services, by notifying the Issuer within 30 days prior thereto. If ODB merges or combines with another registered broker- dealer, this Agreement will automatically transfer to the successor, provided it does not materially prejudice the Issuer.

No Waiver. The failure of either Party to insist upon or enforce strict performance by the other Party of any provision of this Agreement, or to exercise any right under this Agreement, shall not be construed as a waiver or relinquishment to any extent of such Party’s right to assert or rely upon any such provision or right in that or any other instance; rather the same shall be and remain in full force and effect.

Entire Agreement. This Agreement and the Terms of Service constitute the entire agreement between the Parties, superseding all prior understandings and representations. Defined terms in this Agreement have the meanings set forth herein; capitalized terms not defined are defined in the Terms of Service. In the event of a conflict between this Agreement and the Terms of Service, this Agreement prevails.

Severability; Survival. If any provision of this Agreement is found unenforceable by a party of competent jurisdiction, the remainder of the Agreement shall remain in full force and effect. Upon the expiration or termination of this Agreement, Sections 5, 6, 8, 9, 10(d) and 10(f) shall survive and neither the expiration nor termination of this Agreement, however arising, shall impair, terminate or prejudice any accrued rights or remedies of the Parties.

Schedule A – Commissions and Fees

Cash and Securities Commission	The Issuer shall pay to ODB (I) a cash fee the greater of (A) $12,000.00 or (B) six percent (6.0%) of the dollar value of the securities issued to Investors pursuant to the combined proceeds of each Offering at the time of closing (the “Cash Commission”), and (II) a securities commission equivalent to two percent (2.0%) of the dollar value of the Securities issued to Investors pursuant to the combined proceeds of each Offering at the time of closing (the “Securities Commission”, and together with the Cash Commission, the “ODB Commissions”). Such Securities shall be of the same type as those issued by the Issuer in and through each Offering. ODB will comply with Lock-Up Restriction required by FINRA Rule 5110(e)(1) and FINRA Rule 5110(g). All Securities Commissions due to ODB shall be issued pursuant to the registration exemption provided by Section 4(a)(2) of the Securities Act unless otherwise qualified or registered under such. The Issuer agrees that the Securities Commission can be assigned to ODB’s Affiliates at ODB’s sole discretion and without notice, and no further consent from the Issuer is needed for this assignment.
Off-Platform Services Commissions	For each executed transaction resulting from off-platform services for Investors introduced to Issuer via an introduction notice (each, an “Off-Platform Investor”), Issuer shall pay ODB: (i) a cash payment of six percent (6.0%) % of the dollar value of the Securities issued to the Off- Platform Investor (“Off-Platform Cash Commission”), and (ii) two percent (2.0%) of the total number of Securities of the same type issued to the Off-Platform Investor (“Off-Platform Securities Commission”). Together, these payments are the “Off-Platform Services Commissions.” Excluded Investors are listed in Annex A. Off-Platform Services Commissions are payable to ODB even after termination, unless for cause.
Business Advisory Services Fees	The Issuer shall pay $15,000.00, within 7 days of the Effective Date for Business Advisory Services.
Termination Fee	$10,000.00 (the “Termination Fee”).
Payment Processing Fees and Administrative Fees	The Issuer shall pay to ODB, irrespective of the outcome of any offering, all payment processing fees including, but not limited to Stripe Inc., Zero Hash LLC and any other payment processor mutually agreed to by ODB and the Issuer. If the Offering has launched, these fees are typically the greater of $2,500 or approximately 2% of an Offering’s proceeds. The Issuer shall reimburse ODB for administrative fees associated with the Offering as outlined in Republic’s Terms of Service.
Bad Actor Checks and Escrow Set-Up Fee	ODB utilizes its Affiliate, Republic Core LLC, to facilitate the opening of escrow accounts and the completion of statutorily required bad actor checks. Issuer will pay Republic Core LLC $3,000 promptly, after the commencement of an Offering for such services. In the event an Offering is unsuccessful, an invoice shall be issued to the Issuer within 7 days of the withdrawn or canceled Offering requesting remittance of payment for such fees, payable to Republic Core LLC. In the event that no escrow accounts are opened for an Offering, Issuer shall pay Republic Core LLC $1,500.
Additional	Payment Disputes: In the event of a payment dispute or late failure associated with an Investor, Issuer shall solely bear the total costs related to the payment dispute or late failure (including, without limitation, repaying the funds to the Investor). In the event the payment processor (including, without limitation, Stripe Inc.) requires ODB to front the funds associated with the payment dispute or late failure, Issuer shall immediately repay ODB said funds and costs associated therewith, and failure to do so is deemed a material breach of this Agreement.
	Zero Hash Refund Policy: Issuer acknowledges and agrees to ODB’s refund policy regarding cryptocurrency subscriptions processed through Zero Hash LLC, as set forth in the Terms of Service. Issuer further agrees that any overpayment amounts of less than $25 shall be deemed a non- refundable gift from the applicable subscriber to the Issuer.
Custodial Fees	Custodial Fees are $5.00 per Investor per Custodial Account, per year (collectively, the “Custodial Fee”). ODB shall cover the Custodial Fee for the first 1,000 Custodial Accounts for 5 calendar years commencing at the closing date of the Offering. If there are more than 1,000 Custodial Accounts for the Offering, the Issuer shall pay $5.00 per Custodial Account. After 5 calendar years from the closing date of the Offering, the Issuer shall cover all Custodial Fees, paid directly to ODB (or directly to the Custodian, as determined by ODB) until the termination of such Custodial Accounts. The Issuer acknowledges and understands that such Custodial Fees are subject to change based on vendor cost.
