$2,500,000.00 April 1, 2024

For value received, Fathom Manufacturing, LLC, a Delaware limited liability company (the “Borrower”), promises to pay to CORE Industrial Partners Fund I, L.P. (the “Lender”) on behalf of CORE Industrial Partners Fund I, L.P., a Delaware limited partnership (“Main Fund”) and CORE Industrial Partners Fund I Parallel, L.P., a Delaware limited partnership (“Parallel Fund” and together with the Main Fund, collectively, the “Lending Parties” and each, a “Lending Party”), on the Maturity Date (as defined herein), the amount of, and to pay interest on, the principal sum outstanding from time to time, as such amount may be increased by PIK Interest (as defined herein) (the “Outstanding Principal Amount”) under this unsecured promissory note, dated as of the Closing Date (as amended, restated, amended and restated, supplemented or otherwise modified from time to time, this “Note”) at the rates set forth in this Note.

The Lending Parties have agreed to make the Term Loan (as defined herein) available to the Borrower in consideration of the Borrower’s covenants and performance hereunder and the guarantee of the Borrower’s payment and performance hereunder by the Guarantors (as defined herein). The Note Parties (as defined herein) will derive substantial direct and indirect benefits from the Term Loan to the Borrower pursuant to this Note and are willing to have Borrower execute and deliver this Note in order to induce the Lending Parties to make the Term Loan.

The Term Loan Borrowing.

(a)

Subject to the term and conditions set forth herein, the Lending Parties with a Term Loan Commitment (as defined herein) agree to make a term loan (the “Term Loan”) under this Note to the Borrower, on the Closing Date, in an aggregate amount not to exceed the amount of the Term Loan Commitments. Upon the funding of the Term Loans by each Lending Party on the Closing Date, the Term Loan Commitments shall immediately and automatically be terminated. Each Lending Party is entering into this Note and making the Term Loan hereunder for the benefit of the Borrower and its Subsidiaries and, for the avoidance of doubt, the Borrower may, subject to the notice requirements of this Section 1, repay, refinance or replace this Note and the outstanding Term Loan hereunder, in each case, without premium or penalty.

(b)

The Borrowing shall be made in United States dollars following the Borrower’s irrevocable written notice to the Lender, which notice must be received by the Lender not later than 3:00 p.m. (New York City time) one (1) Business Day prior to Closing Date. Each such notice shall be signed by the chief executive officer, chief financial officer or treasurer of the Borrower and shall specify (i) the requested date of the Borrowing (which shall be a Business Day), (ii) the principal amount of Term Loan to be borrowed and (iii) the account of the Borrower to be credited with the proceeds of such Borrowing.

Interest. Interest on the unpaid Outstanding Principal Amount will accrue at the rate of 5.0% per annum. Interest will be due and payable in arrears on a quarterly basis on the last Business Day of each March, June, September and December of each year during the term of this Note beginning on June 30, 2024 (each an “Interest Payment Date”). With respect to interest due and payable on each Interest Payment Date, such interest shall be payable in kind by increasing the Outstanding Principal Amount of this Note by the amount of interest due on such date (the “PIK Interest”). Following an increase in the Outstanding Principal Amount of the Note as a result of payment of PIK Interest, interest on the unpaid Outstanding Principal Amount will accrue from and after the date of payment of such PIK Interest. All accrued and unpaid interest shall be due and payable on the Maturity Date. Upon the occurrence and during the continuance of an Event of Default (as defined herein), the Note Parties shall pay interest on the

principal amount of all overdue Obligations hereunder at an interest rate equal to the interest rate otherwise in effect hereunder plus 2.0% per annum. Accrued and unpaid interest on past due amounts (including, without limitation, interest on past due interest) shall be due and payable in cash upon written demand.

Payments of Principal and Interest. Borrower shall pay interest on, and repay the principal amount of, this Note as follows:

(a)

Prepayments.

Any payments so made shall be without premium or penalty and shall be applied first to accrued but unpaid interest (including, without limitation, all interest accrued due to the occurrence of an Event of Default), second, to the payment of PIK Interest hereunder until all such PIK Interest is paid and third, to outstanding principal.

(b)

Maturity Date. Borrower shall pay the entire remaining outstanding principal amount of this Note, together with all accrued and unpaid interest thereon (including, without limitation, all interest accrued due to the occurrence of an Event of Default), on September 30, 2024 (the “Maturity Date”).
