        2. Either separately or as the consolidated quotation display, a quotation montage for that security.

      4. No consolidated quotation display or separate quotation montage provided on an interrogation device may exclude any quotation information based upon the market center making available such information: Provided, however, That for purposes of providing the consolidated quotation display or a separate quotation montage for any reported security, quotation information from all reporting market centers which are third market makers may be consolidated to derive a best bid and offer for all such market centers if such interrogation device is capable of displaying, either separately or as part of the consolidated quotation display or separate quotation montage,

        1. identifiers indicating the reporting market center making available such best bid and the reporting market center making available such best offer, and

        2. the quotation size associated with both such best bid and best offer.
