Liability of Joint Account Holders. The joint Account holders are jointly and severally liable to the Firm for any debts, obligations or liabilities arising in connection with the Account. Each joint Account holder jointly and severally agrees to indemnify and hold the Firm harmless from, and to promptly pay the Firm on demand, any and all losses arising from the joint Account or any debit balance due thereon. As continuing collateral security for the payment of such debts, obligations or liabilities, which are now or which may in the future be owing by each joint Account holder to the Firm, each joint Account holder pledges to the Firm all of the joint Account holders’ collateral, whether held in the Account or in any other Account with the Firm in which any of the joint Account holders have an interest and whether or not any amount owing relates to the collateral pledged. This security is in addition to and not in substitution for the rights and remedies the Firm otherwise would have.
