RECITALS 
 WHEREAS,
Buyer, Sponsor and the Individual Class B Holders have entered into the Forfeiture and Support Agreement; 

 WHEREAS, pursuant to Section 13 of the Forfeiture and Support Agreement, such agreement
may only be changed, amended or modified by a written instrument executed by all parties thereto (including each addressee thereof); and 

WHEREAS, Buyer, Sponsor, the Individual Class B Holders, CORE, Fathom and the Fathom Blockers desire to amend certain provisions of the
Forfeiture and Support Agreement as set forth herein. 
 NOW, THEREFORE, in consideration of the premises and mutual agreements hereinafter
set out and of other good and valuable consideration (the receipt and sufficiency of which are hereby acknowledged), the parties hereby agree as follows: 

1.    Amendments to the Forfeiture and Support Agreement. Effective as of the date hereof: 

a.    Amendment to Section 2. Section 2 of the Forfeiture and Support Agreement is hereby
amended and replaced in its entirety with the following: 
 “Effective upon and subject to the Closing, (a) Sponsor and each
Individual Class B Holder shall irrevocably automatically forfeit and surrender, for no additional consideration and without any further action on the part of any other Person, its respective allocable portion of the Forfeited Shares (as
defined below), which would otherwise be held by the Sponsor or such Individual Class B Holders as a result of the automatic conversion of shares of Altimar Class C Common Stock after giving effect to the Anti-dilution Waiver (the
“Forfeiture”), the Domestication and the Closing and (b) Buyer acknowledges and agrees to, immediately following the Forfeiture, issue 1,293,750 additional newly issued shares of Altimar Class A Common Stock which shall be
allocated in accordance with the terms and conditions of the Business Combination Agreement and the Allocation Statement.” 

b.    Amendment to Section 11. Clause (a) of Section 11 of the Forfeiture and Support
Agreement is hereby amended to replace “$15.00 per share” with “$12.50 per share”. 

c.    Amendment to Section 12(d). Section 12(d) of the Forfeiture and Support Agreement is
hereby amended and replaced in its entirety with the following: 
 ““Forfeited Shares” means 2,587,500 aggregate shares
of Altimar Class A Common Stock allocated among Sponsor and the Individual Class B Holders as set forth in Schedule B. “Forfeited” shall have a correlative meaning to “Forfeiture” for purposes of this
Agreement.” 

  
 2 

 d.    Additional Schedules. Schedule A and Schedule
B to this Letter Agreement are hereby added, respectively, as Schedule A and Schedule B to the Forfeiture and Support Agreement. 

2.    Miscellaneous. The terms, conditions and provisions of the Forfeiture and Support Agreement, as amended by
this Letter Agreement, remain in full force and effect. The execution, delivery and effectiveness of this Letter Agreement shall not operate as a waiver of any right, power or remedy of any party under the Forfeiture and Support Agreement, nor
constitute a waiver or amendment of any provision of the Forfeiture and Support Agreement. This Letter Agreement shall be governed by, and otherwise construed in accordance with, the terms of the Forfeiture and Support Agreement, as though the other
provisions of this Letter Agreement were set forth in the Forfeiture and Support Agreement. This Letter Agreement may be executed in counterparts (including by means of facsimile or scanned and emailed signature pages), any one of which need not
contain the signatures of more than one party, but all such counterparts taken together shall constitute one and the same agreement.
