receive instructions to withdraw Banco Sabadell shares that are earlier than the expiration date and time specified in this offer to exchange/prospectus. You should contact your broker or other securities intermediary to determine the cut-off date and time that applies to you.

Extension, Termination and Amendment

BBVA may extend the period of time in which the exchange offer is open one or more times in accordance with the provisions of article 23 of the
Spanish Takeover Regulation, provided that such extension complies with U.S. securities laws, and, provided further that the acceptance period does not exceed 70 calendar days and that any extension is communicated in advance to the CNMV. The
extension of the acceptance period, if any, must be announced at least three calendar days before the then-scheduled expiration date of the acceptance period, indicating the circumstances that motivate such extension. If BBVA extends the period of
time during which the exchange offer is open, the exchange offer will expire at the latest time and date to which BBVA extends the exchange offer. The CNMV may also extend the exchange offer acceptance period at its own discretion under the
circumstances set forth in the Spanish Takeover Regulation, including (i) following a supplement to the offering documents published (or that will be published) in Spain when the CNMV considers that the materiality of the information disclosed
in such supplement makes the extension of the exchange offer appropriate; or (ii) in other cases where the CNMV deems such extension necessary, through a justified resolution and to the extent legally possible.

During any such extension, all Banco Sabadell shares validly tendered into, and not withdrawn from, the exchange offer prior to that date will
remain subject to the exchange offer, subject to your right to withdraw your Banco Sabadell shares. You should read the discussion below under “—Procedure for Tendering—Withdrawal Rights” for more information about your ability
to withdraw tendered shares.
