In exchange for assuming these obligations, Counterparty received cash payments from the financial institutions in an aggregate amount of approximately $1.6 billion on or about the date of entering into the Contracts.

F3 · derivative.exercise_price: [continued from FN (2)] Counterparty also pledged 10,500,000 shares of Common Stock (the "Pledged Shares") in the aggregate to the financial institutions or their affiliates to secure its obligations under the Contracts and retained certain dividend and voting rights on the Pledged Shares. In respect of each valuation date under the Contracts, the aggregate number of shares of Common Stock to be delivered to the financial institutions or cash to be delivered to (or by) the financial institutions is to be determined as follows: Counterparty may, at its election, subject to certain conditions (1) be obligated to deliver to the financial institutions the full number of shares to which such valuation date relates and will receive an additional cash payment determined as follows:
