WAIVER OF LOCK-UP PERIOD 

This AMENDMENT NO. 1 TO THE AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT AND WAIVER OF
LOCK-UP PERIOD (this “Amendment”), dated as of October 25, 2022, amends that certain Amended and Restated Registration Rights Agreement, dated April 21, 2022 (the
“Registration Rights Agreement”), by and among LMF Acquisition Opportunities, Inc., a Delaware corporation (the “Company”), and the investors listed on the signature pages thereto (individually, an
“Investor” and collectively, the “Investors”). 
 WHEREAS: 

A. The parties to this Amendment desire to hereby amend the Registration Rights Agreement in the manner set forth herein. 

B. Section 2.12(b) of the Registration Rights Agreement prohibits the Transfer of any of the Merger Shares held by Holders until the date
that is the earlier of (1) the twelve month anniversary of the Closing and (2) the last sale price of the Common Stock equals or exceeds $12.00 per share (as adjusted) for any 20 trading days within any
30-trading day period commencing at least 150 days after the Merger (the “Lock-up Period”). 

C. Section 2.12(d) of the Registration Rights Agreement currently requires that any release of any Investor from the lock-up provisions of Section 2.12 of the Registration Rights Agreement also requires the release of all other Investors from the lock-up provisions of Section 2.12
of the Registration Rights Agreement. 
 D. The parties to this Amendment desire to remove the requirement that a release of one Investor
requires a release of all Investors and waive the enforcement of the Lock-up Period with respect to David Humes and Michael Humes. 

E. As required by Section 3.1 of the Registration Rights Agreement, (i) the Company, (ii) the Holders holding a majority of the
Registrable Securities issued to the Sponsor, and (iii) the Holders holding a majority of the Merger Shares that are Registrable Securities have executed this Amendment (the “Consenting Investors”). 

NOW, THEREFORE, the Company and each of the Consenting Investors hereby agree as follows, effective in the corresponding order: 

1. Section 2.12(d) of the Registration Rights Agreement is hereby deleted and removed in its entirety. 

2. Section 3.1 of the Registration Rights Agreement is hereby amended and restated as follows: 

 “Amendment. Except as expressly provided herein, neither this Agreement nor any
term hereof may be amended, waived, discharged, or terminated other than by a written instrument referencing this Agreement and signed by (i) the Company, (ii) the Holders holding a majority of the Registrable Securities issued to the
Sponsor and (iii) the Holders holding a majority of the Merger Shares that are Registrable Securities; provided, however, that if any amendment, waiver, discharge, or termination operates in a manner that treats any Holder
different from other Holders, the consent of such Holder that is treated differently shall also be required for such amendment, waiver, discharge, or termination. Persons who become assignees or other transferees of Registrable Securities in
accordance with this Agreement after the date of this Agreement may become parties hereto, by executing a counterpart of this Agreement without any amendment of this Agreement pursuant to this paragraph or any consent or approval of any other
Holder. Any amendment, waiver, discharge, or termination effected in accordance with this paragraph shall be binding upon each Holder and each future holder of all such securities of such Holder.” 

3. That the Company and each of the Consenting Investors, hereby waive their right to enforce the obligations of David Humes and Michael Humes
under Section 2.12 of the Registration Rights Agreement and agree that the Merger Shares received at Closing by David Humes and Michael Humes shall not be restricted pursuant to the terms set forth in Section 2.12 of the Registration
Rights Agreement. 
 4. Except as specifically set forth in this Amendment, all of the terms and provisions of the Registration Rights
Agreement shall continue to remain in full force and effect. Capitalized terms appearing in this Amendment and not otherwise defined herein shall have the meanings ascribed thereto in the Registration Rights Agreement. 

5. This Amendment may be executed in any number of counterparts, each of which shall be deemed to be an original, and all of which together
shall constitute one document. This Amendment, together with the Registration Rights Agreement, contains the final, complete, and exclusive expression of the parties’ understanding and agreement concerning the matters contemplated herein and
supersedes any prior or contemporaneous agreement of representation, oral or written, among them. This Amendment shall be governed by, and construed and enforced in accordance with the laws of the State of Delaware without reference to principles of
choice of law thereunder.

 Attention: Maier Joshua Tarlow 

Re: Common Stock Purchase Agreement 
 Ladies and
Gentlemen: 
 This letter (the “Letter Agreement”) is entered into as of October 28, 2022, and confirms our
agreement to amend that certain Common Stock Purchase Agreement, dated as of August 23, 2022 (the “Purchase Agreement”), by and among Tumim Stone Capital LLC, a Delaware limited liability company (the
“Investor”), LMF Acquisition Opportunities, Inc., a Delaware blank check company established for the purpose of entering into a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or similar
business combination with one or more businesses (“LMFAO”), and SeaStar Medical, Inc., a Delaware corporation (“SeaStar Medical”). Capitalized terms used and not expressly defined herein shall have the
meanings for such terms set forth in the Purchase Agreement. 
 Upon the Business Combination Closing on the Business Combination Closing
Date, LMFAO will change its name to “SeaStar Medical Holding Corporation” and, therefore, all references in this Letter Agreement to the “Company” shall mean “SeaStar Medical Holding Corporation,
a Delaware corporation” from and after the Business Combination Closing. 
 1. Notwithstanding anything to the contrary in the Purchase
Agreement, with respect to the Commitment Fee and Commitment Shares, the parties agree that the Commitment Fee shall be paid to Investor as follows (and that the Purchase Agreement shall be amended, at or immediately prior to the Closing on the
Closing Date under the Purchase Agreement, to, among other things, reflect the below terms in this Section 1): 
  

	 	a.	 Either LMFAO or the Company shall pay to the Investor $1,000,000 of the Commitment Fee in cash by wire transfer
or immediately available funds to an account designated by the Investor to LMFAO, not later than 5:30 p.m., Eastern time, on the Business Combination Closing Date; 

 

	 	b.	 The Company shall pay to the Investor $500,000 of the Commitment Fee in cash by wire transfer or immediately
available funds to an account designated by the Investor to the Company, not later than the earliest of (i) the 30th calendar day immediately following the Effective Date of the Initial Registration Statement, (ii) the 30th calendar day immediately following the Effectiveness Deadline of the Initial Registration Statement, and (iii) not later than 4:00 p.m. (New York City time) on the second (2nd) Trading Day immediately after the date on which written notice of termination is delivered by the Company or the Investor (as applicable) to the other party pursuant to Section 8.2 and
Section 10.4 of the Purchase Agreement, as amended (and no such termination of the Purchase Agreement, as amended, shall become effective unless and until all of such $500,000 of the Commitment Fee shall have been paid to the Investor pursuant
to and in accordance with the Purchase Agreement, as amended); and 

	 	c.	 The Company shall pay to the Investor the balance of the Commitment Fee, or $1,000,000, as Commitment Shares at
such time and calculated in such manner and otherwise issued in accordance with the terms for the issuance of the Commitment Shares as set forth in the Purchase Agreement, as amended. 

2. Except as set forth in Section 1 of this Letter Agreement, all of the provisions of the Purchase Agreement (as it
shall be amended at or immediately prior to the Closing) shall remain in full force and effect as of and from and after the Closing on the Closing Date, each according to its terms as set forth in the Purchase Agreement (as so amended), and shall
not be amended, changed, modified or superseded in any way whatsoever by this Letter Agreement.
