For completeness, here's the Roster Emergency Exception section:
50.10(e) Roster Emergency Exception. In the event that (i) a Club has Payroll Room less than the sum of the Minimum Paragraph 1 NHL Salary and $100,000 (i.e., that Club's Averaged Club Salary is greater than the Upper Limit minus the Minimum Paragraph 1 NHL Salary minus $100,000); (ii) a Player on such Club becomes unfit or unable to play (i.e., is injured, ill or disabled and unable to perform his duties as a hockey Player) or is suspended; (iii) such Club is unable to sign and/or Recall a Player with an Averaged Amount equal to the Minimum Paragraph 1 NHL Salary plus $100,000 under the Bona Fide Long-Term Injury/Illness Exception; (iv) as a result of such Player being unfit or unable to play or suspended and the Club having Payroll Room less than the sum of the Minimum Paragraph 1 NHL Salary and $100,000, the Club has fewer than eighteen (18) skaters and two (2) goalies ("18 and 2") on its Playing Roster (pursuant to Section 16.4(c)); and (v) the Club played its previous game with fewer than 18 and 2 (a "Roster Emergency"), then such Club may, beginning with the second game and continuing with all subsequent games and without any charge to the Club's Averaged Club Salary for the duration of such Roster Emergency, add to its Playing Roster the requisite number of "emergency replacement" Player(s), provided, however, that (i) each such Player may not have an Averaged Amount that is more than the then-applicable Minimum Paragraph 1 NHL Salary plus $100,000 (e.g., $625,000 in 2012-13); and (ii) each such Player may only remain on that Club's Active Roster during the period of the "Roster Emergency."
(i) The Paragraph 1 NHL Salary and Bonus of any Player added to the Playing Roster pursuant to this Section shall be included in the Players' Share.
(ii) No Club shall be limited in the number of times it may invoke the Roster Emergency Exception in any League Year, provided that the Exception is at all times invoked in full compliance with this Section 50.10(e).
