Dear Mark:


 


In recognition of your service
as a member of the Board of Directors of Rotech Healthcare Holdings Inc. (the “Board”) in connection with its initial
public offering (“IPO”), the Board has selected you to receive a special transaction bonus in connection with the IPO
(the “Transaction Bonus”), payable in a combination of cash, stock options and restricted stock units, as set forth
below. Please read the terms of this letter carefully.


 


1.            Forms
of Payment; Vesting. Provided you continue to serve as a member of the Board through the date of the IPO (the “IPO Date”),
you will be entitled to receive the Transaction Bonus, which shall have an aggregate value of $390,000 and shall be payable in the following
forms:


 


		(ii)	a cash payment in the amount of $130,000, which shall vest and be paid to you on the IPO Date;



 


		(iii)	a stock option award granted under the Rotech Healthcare Holdings Inc. 2021 Omnibus Incentive Plan (the
 “Stock Plan”) with a grant date fair value equal to $130,000 determined as of the IPO Date and a five (5)-year term
(the “Transaction Stock Option Award”), which shall vest in equal installments on each of the 6-, 12- and 18-month
anniversaries of the IPO Date, provided you continue to serve as a member of the Board through each applicable vesting date, and



 


		(iv)	a restricted stock unit award granted under the Stock Plan with a grant date fair value equal to $130,000
determined as of the IPO Date (the “Transaction RSU Award”), which shall vest in equal installments on each of the
6-, 12- and 18-month anniversaries of the IPO Date, provided you continue to serve as a member of the Board through each applicable vesting
date.



 


2.            Treatment
on Termination. In the event your service as a member of the Board is terminated by Rotech Healthcare Holdings Inc. (the “Company”)
following the IPO Date without Cause (as defined under the Stock Plan) or due to your failure to be re-elected at an annual stockholders’
meeting, any portion of the Transaction Stock Option Award and Transaction RSU Award that is unvested as of the date of your termination
from the Board shall immediately vest in full and any vested portion of the Transaction Stock Option Award shall remain outstanding for
the remainder of its original term. In the event your service as a member of the Board is terminated due to your resignation for any reason
following the IPO Date, any portion of the Transaction Stock Option Award and Transaction RSU Award that is unvested as of the date of
your resignation shall be forfeited and cancelled for no consideration and any vested portion of the Transaction Stock Option Award shall
be treated in accordance with the terms of the Stock Plan and the applicable award agreement. In the event your service as a member of
the Board is terminated by the Company for Cause following the IPO Date, any portion of the Transaction Stock Option Award (whether vested
or unvested) and any unvested portion of the Transaction RSU Award that remains outstanding as of the date of such termination shall be
forfeited and cancelled for no consideration.
