	 	Re:	 Initial Public Offering 



Gentlemen: 
 This letter agreement (this
“Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) to be entered into by and between Northern Star Acquisition Corp., a Delaware
corporation (the “Company”), and Citigroup Global Markets Inc., as representative (the “Representative”) of the several Underwriters named in Schedule 1 thereto (the
“Underwriters”), relating to an underwritten initial public offering (the “IPO”) of the Company’s units (the “Units”), each comprised of one share of the Company’s
Class A common stock, par value $0.0001 per share (the “Common Stock”), and one-third of one redeemable warrant, each whole warrant exercisable for one share of Common Stock (each, a “Warrant”).
Certain capitalized terms used herein are defined in paragraph 12 hereof. 
 In order to induce the Company and the Underwriters to enter
into the Underwriting Agreement and to proceed with the IPO, and in recognition of the benefit that such IPO will confer upon the undersigned, and for other good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the undersigned hereby agrees, severally but not jointly, with the Company as follows: 
 1. If the Company solicits approval
of its stockholders of a Business Combination, the undersigned shall vote all shares of Common Stock and Founders’ Common Stock (including shares of Common Stock issuable upon conversion of shares of Founders’ Common Stock) beneficially
owned by him or her, whether acquired before, in, or after the IPO, in favor of such Business Combination. 
 2. In the event that the
Company fails to consummate a Business Combination within the time period set forth in the Company’s Amended and Restated Certificate of Incorporation, as the same may be amended from time to time, the undersigned will, as promptly as possible,
cause the Company to (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible, but not more than 10 business days thereafter, redeem the IPO Shares, at
a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account net of interest released to
the Company as permitted pursuant to that certain Investment Management Trust Agreement to be entered into by the Company, divided by the number of then outstanding IPO Shares, which redemption will completely extinguish public stockholders’
rights as stockholders (including the right to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders and
the Company’s board of directors, dissolve and liquidate, subject in the cases of clauses (ii) and (iii) to the Company’s obligations under Delaware law to provide for claims of creditors and other requirements of applicable law.
The undersigned hereby waives any and all right, title, interest or claim of any kind in or to any distribution of the Trust Account (“Claim”) with respect to the shares of Founders’ Common Stock owned by the undersigned
and hereby waives any Claim the undersigned may have in the future as a result of, or arising out of, any contracts or agreements with the Company and will not seek recourse against the Trust Account for any reason whatsoever. The undersigned
acknowledges and agrees that there will be no distribution from the Trust Account with respect to any Warrants, all of which will terminate on the Company’s liquidation. [In the event 












 
of the liquidation of the Trust Account upon the failure of the Company to consummate its initial Business Combination within the time period set forth in the Company’s Amended and Restated
Certificate of Incorporation, as the same may be amended from time to time, the undersigned agrees to indemnify and hold harmless the Company against any and all loss, liability, claim, damage and expense whatsoever (including, but not limited to,
any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether pending or threatened) to which the Company may become subject as a result of any claim by (i) any third party for
services rendered or products sold to the Company or (ii) any prospective target business with which the Company has discussed entering into a transaction agreement (a “Target”); provided, however, that such
indemnification of the Company by the undersigned (x) shall apply only to the extent necessary to ensure that such claims by a third party for services rendered or products sold to the Company or a Target do not reduce the amount of funds in
the Trust Account to below (i) $10.00 per IPO Share or (ii) such lesser amount per IPO Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets, in each case net
of the amount of interest which may be withdrawn to pay taxes, (y) shall not apply to any claims by a third party or Target who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is
enforceable) and (z) shall not apply to any claims under the Company’s indemnity of the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended.] 1 
 3. The undersigned acknowledges and agrees that prior to entering into a Business
Combination with a target business that is affiliated with any Insiders of the Company or any of their affiliates, such transaction must be approved by a majority of the Company’s disinterested independent directors and the Company must obtain
an opinion from an independent investment banking firm, or another independent entity that commonly renders valuation opinions, that such Business Combination is fair to the Company (and/or its stockholders) from a financial point of view. 

4. Neither the undersigned nor any affiliate of the undersigned will be entitled to receive and will not accept any compensation or other cash
payment prior to, or for services rendered in order to effectuate, the consummation of the Business Combination; provided that the Company shall be allowed to make the payments set forth in the Registration Statement under the caption
“Prospectus Summary – The Offering – Limited payments to insiders.” 
 5. Intentionally Omitted. 

6. (a) The undersigned agrees that the shares of Founders’ Common Stock may not be transferred, assigned or sold (except to the permitted
transferees expressly described in the Registration Statement under “Principal Shareholders—Restrictions on Transfers of Founder Shares and Private Placement Warrants”; provided that in the case of clauses (a) through (h)
thereof, such permitted transferees enter into a written agreement with the Company agreeing to be bound by the transfer restrictions and the other restrictions contained in this Agreement and by the same agreements entered into by the
Company’s initial stockholders with respect to such securities (including provisions relating to voting, the Trust Account and liquidation distributions described in the Registration Statement)) until the earlier to occur of: (1) one year
after the consummation of a Business Combination and (2) subsequent to a Business Combination, (x) the date on which the Company completes a liquidation, merger, share exchange or other similar transaction that results in all of its
shareholders having the right to exchange their shares of Common Stock for cash, securities or other property, or (y) if the last reported sale price of the Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock
dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Company’s initial Business
Combination. 
 (b) The undersigned will not, without the prior written consent of the Representative, offer, sell, contract to sell,
pledge, hedge or otherwise dispose of (or enter into any transaction that is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or
otherwise) by the undersigned or any affiliate of the undersigned or any person in privity with the undersigned or any affiliate of the undersigned), directly or indirectly, including the filing (or participation in the filing) of a registration
statement with the Securities and Exchange Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934,
as amended, and the rules and regulations of the Securities and Exchange Commission promulgated thereunder with respect to, any other Units, Common Stock, Warrants of the Company or any securities convertible into, or exercisable, or exchangeable
for, Common Stock or publicly announce an intention to effect any such transaction, for a period of 180 days after the date of the Underwriting Agreement.

 (c) [The undersigned agrees that until 30 days after the Company consummates a Business
Combination, the undersigned’s Private Warrants will not be transferable (except to the permitted transferees expressly described in the Registration Statement under “Principal Shareholders—Restrictions on Transfers of Founder Shares
and Private Placement Warrants”; provided that in the case of clauses (a) through (h) thereof, such permitted transferees enter into a written agreement with the Company agreeing to be bound by the transfer restrictions and the other
restrictions contained in this Agreement and by the same agreements entered into by the Company’s initial stockholders with respect to such securities (including provisions relating to voting, the Trust Account and liquidation distributions
described in the Registration Statement)).] 2

 15. This Agreement shall be binding on the undersigned and such person’s respective
