Consulting Services Agreement financial

"the Company entered into a Consulting Services Agreement (the “Consulting Agreement”) with Patrick Gruber LLC"

transitional consulting services financial

"Pursuant to the Consulting Agreement, the Consultant will provide transitional consulting services to the Company."

confidentiality financial

"The Consulting Agreement contains customary provisions regarding confidentiality, ownership of work product, and indemnification."

Confidentiality is the practice of keeping private information—such as business plans, financial data, personnel matters, or trade secrets—restricted to a limited group rather than shared publicly. For investors it matters because breaches can change a company’s competitive edge, trigger legal or regulatory problems, or move markets if sensitive information becomes public; think of it as a lockbox that protects value and reduces unexpected risk.

ownership of work product financial

"The Consulting Agreement contains customary provisions regarding confidentiality, ownership of work product, and indemnification."

indemnification financial

"The Consulting Agreement contains customary provisions regarding confidentiality, ownership of work product, and indemnification."

A contractual promise to cover losses, expenses, or legal claims that arise from specified events, such as breaches of representations or third‑party lawsuits. For investors, indemnification matters because it shifts potential financial risk and future cash outflows from one party to another, similar to a friend agreeing to pay your bill if you’re sued, and can affect deal value, expected returns, and contingent liabilities on the balance sheet.
