Customer Agreement

Effective Date: May 1, 2026

1. OVERVIEW

Welcome to Battle Creek State Bank (“BCSB”). This Customer Agreement (this “Agreement”) outlines the terms and conditions governing your relationship as a customer (“Customer”) introduced to BCSB through Telcoin Digital Asset Bank (“TDAB”) functions. This Agreement establishes the terms and conditions of using your BCSB Digital Cash Transaction Account, a bank account provided by BCSB (“BCSB Account”), in connection with the Telcoin Wallet application provided through TDAB, or other wallet application approved by and compatible with TDAB (“TDAB Wallet”).

Please read this Agreement carefully. BCSB is a Nebraska state chartered financial institution. You, as the Customer, are applying to open an account, and serve as the beneficial owner of that account, with the rights, responsibilities, and privileges described in this Agreement. You agree to manage your account in accordance with applicable laws and regulations, as described in more detail below.

As a Customer of BCSB, you agree to the terms and conditions of opening an account as provided in the disclosures required to open a BCSB Account, which is a demand deposit account with limited use as described in this Agreement.

BCSB Online Banking Services. This Agreement outlines the terms and conditions for accessing and using BCSB’s online digital banking platform.

2. PURPOSE AND NATURE OF THE BCSB ACCOUNT

The BCSB Account is a limited-purpose, transactional deposit account established solely for the purpose of facilitating the purchase and redemption of eUSD Digital Cash stablecoins (“eUSD”) issued by TDAB. The BCSB Account is designed to receive incoming funds from you for the purchase of TDAB-issued eUSD and to receive fiat currency proceeds when you redeem or exchange TDAB-issued eUSD for United States Dollars. The BCSB Account is not a general-purpose checking, savings or investment account. The BCSB Account may not be used for purposes unrelated to transactions involving TDAB-issued eUSD, except as otherwise determined by BCSB in its sole discretion. The BCSB Account will not at any time hold any digital assets of any kind, including without limitation any TDAB-issued eUSD. The BCSB Account will receive and distribute fiat currency only, and only for the limited purposes described in this Agreement.

3. ELIGIBILITY AND ACCOUNT OPENING REQUIREMENTS

In order to open a BCSB Account, you must:

  • Be at least 18 years of age.

  • Agree to the BCSB eSign Consent Agreement.

  • Maintain an active account with TDAB.

In addition, you must complete BCSB’s account application and provide all information and documentation required by BCSB, including valid identification that verifies your identity in accordance with applicable federal and state laws and regulations, including the Bank Secrecy Act, the USA PATRIOT Act and all applicable money-laundering requirements. BCSB reserves the right to decline to open a BCSB Account for any reason permitted by applicable law. By applying for a BCSB Account, you represent and warrant that all information you provide is true, accurate, and complete, and you agree to promptly notify BCSB of any changes to such information.

Currently a minimum deposit is not required for the BCSB Account. If a minimum deposit is required in the future, each BCSB Account owner will be sent an electronic notice 60 days prior to changes regarding the amount and conditions constituting that minimum.

If a BCSB Account is opened for you, deposits to that BCSB Account may be funded through approved electronic transfer platforms as well as using a digital wallet application using the Telcoin Wallet.

Additional banking products and services may be made available to you by BCSB in the future. A change to the banking products and services will be communicated to you electronically.

4. NO FDIC INSURANCE

ALTHOUGH BCSB IS A NEBRASKA STATE-CHARTERED FINANCIAL INSTITUTION WITH DEPOSITS INSURED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION (“FDIC”), THE FUNDS IN YOUR BCSB ACCOUNT WILL NOT BENEFIT FROM THAT DEPOSIT INSURANCE. BECAUSE OF THE LIMITED-PURPOSE NATURE OF THE BCSB ACCOUNT. YOU ACKNOWLEDGE AND AGREE THAT FUNDS DEPOSITED IN THE BCSB ACCOUNT WILL NOT BE INSURED BY THE FDIC OR ANY OTHER GOVERNMENTAL AGENCY. NO FEDERAL OR STATE GOVERNMENT AGENCY HAS GUARANTEED OR INSURED THE DEPOSITS IN THE BCSB ACCOUNT. YOU ASSUME ALL RISK OF LOSS WITH RESPECT TO FUNDS DEPOSITED IN YOUR BCSB ACCOUNT.

The BCSB Account is structured as a transactional pass-through account in connection with eUSD transactions facilitated by TDAB. Because all funds deposited into your BCSB Account are swept daily to an account owned by TDAB, as described in Section 6 of this Agreement, and because your BCSB Account will not have a positive account balance at the end of any business day (when banks typically are closed by the FDIC and other applicable bank regulatory agencies), no FDIC insurance coverage will be available for your deposits in the event of bank failure. As a result, you should not rely on FDIC insurance or any similar deposit protection with respect to funds deposited or otherwise transferred to your BCSB Account.

5. USE OF ACCOUNT

  • As noted in Section 2 above, the BCSB Account is a limited-purpose, transactional deposit account only. The intended use of the BCSB Account is for facilitating the purchase and redemption of eUSD issued by TDAB, as well as other related activities and services offered by TDAB pursuant to your separate customer agreement with TDAB.

  • At the date of this Agreement, traditional banking products and services are generally not offered by BCSB for TDAB customers who open a BCSB Account.

  • Account balances can be viewed through the TDAB Wallet.

  • Your BCSB Account balance will generally remain a zero balance at the end of each business day, as describe in Section 6 of this Agreement.

    • Due to the nature of electronic transfer, your end-of-day balance in your BCSB Account will be zero USD; however, your available balance as shown in your TDAB Wallet will be based on your eUSD balance in your TDAB Wallet, based on funds availability through TDAB.

    • Amounts shown as an available balance in your TDAB Wallet when the balance of your BCSB Account is zero are not deposits at BCSB and are not insured by the FDIC, as described in Section 4 of this Agreement.

  • Funds shown as available funds in your TDAB Wallet will be moved by TDAB through your TDAB Wallet using the electronic choices available through the wallet.

  • Any additional USD deposited into your BCSB Account will result in automatic purchase of eUSD from TDAB, into your TDAB Wallet, and will be swept as a standard process per this Agreement and your separate customer agreement with TDAB to settle the eUSD purchase.

  • Any USD payment request submitted through the TDAB Wallet against your BCSB Account will result in automatic sale of eUSD in your TDAB Wallet to TDAB, and the USD proceeds will be transferred into your BCSB Account to settle the USD payment per the TDAB and BCSB Customer Agreements.

  • Unauthorized account usage may result in account suspension including closure. Unauthorized usage can include but not limited to account takeover, fraud of any measure, including unusual activity per the Bank standard risk appetite.

6. DAILY SWEEP OF ACCOUNT BALANCES

You acknowledge and agree that all balances in the BCSB Account will be swept on each business day into a deposit account owned by TDAB at BCSB or at such other institution as TDAB may designate (the "TDAB Settlement Account"). The daily sweep will occur at the end of each business day or at such other time as BCSB may determine. Following the daily sweep, the balance in your BCSB Account will be zero or such nominal amount as BCSB may require from time to time to maintain the BCSB Account.

The purpose of the daily sweep is to facilitate the issuance of eUSD by TDAB in exchange for your deposited funds. Once your funds are swept to the TDAB Settlement Account, TDAB will issue eUSD to your TDAB Wallet in accordance with the terms of your separate customer agreement with TDAB. BCSB has no responsibility or liability for the issuance, value, redemption, or performance of any eUSD issued by TDAB, and BCSB makes no representations or warranties regarding eUSD issued by TDAB.

7. FEES AND CHARGES

  • BCSB may charge fees for the maintenance and operation of the BCSB Account as set forth in BCSB’s fee schedule, which may be amended from time to time.

  • BCSB does not currently charge monthly account maintenance fees. If monthly account maintenance fees are applied in the future, each BCSB account owner will be sent an electronic notice 60 days prior to changes regarding the amount and conditions constituting that monthly account maintenance fee.

  • Overdraft fees, and ATM fees may apply, and may be assessed by BCSB in USD or TDAB in eUSD.

  • Additional fees and charges from TDAB and the TDAB Wallet may apply, are governed by your separate customer agreement with TDAB.
