These players are Restricted Free Agents, do the same rules apply?

read section 2 and beyond…
From Article 50.5(e)(iv)(C):
For a Club that wishes to sign an Unrestricted Free Agent following the commencement of a season (i.e., after the first day of the NHL Regular Season), if the Club signs such a Player to an SPC after December 1, then the following rules shall apply:
(1) In order for the Club to sign such a Player to a one-year SPC after December 1 of a season, the Club must have Payroll Room equal to or in excess of the remaining Player Salary and Bonuses to be earned by the Player under the SPC in that League Year; and
(2) In order for a Club to sign such a Player to a multi-year SPC after December 1 of a season, the Club must have Payroll Room equal to or in excess of the Averaged Amount of the Player Salary and Bonuses for the remainder of such season. If, however, the Averaged Amount of the SPC exceeds the Club’s Payroll Room for the then-current League Year, the Club may still sign such SPC, provided that it has Payroll Room and, if such Payroll Room is insufficient to acquire the SPC, it has an amount equal to one or more SPCs that will expire at the end of such League Year, in an amount equal to or in excess of the amount by which the Averaged Amount exceeds the Club’s Payroll Room (the “Tagged Payroll Room”). Until such time as the Club has or makes Payroll Room in the current year in excess of such Tagged Payroll Room, the Club may not engage in any Player transactions requiring Payroll Room, including but not limited to, acquiring an SPC or “extending” or entering into a new SPC (the “Tagging Rule”). In the event the Club does have or creates such excess Payroll Room, it may use such excess Payroll Room in accordance with the terms of this Agreement.
