	Re:	Initial Public Offering 

 Ladies
and Gentlemen: 
 The undersigned stockholder, officer and director of Builder Acquisition Corp. (“Company”), in consideration of
JMP Securities LLC (“JMP Securities”) agreeing to underwrite an initial public offering (“IPO”) of the Company’s units (“Units”), each comprised of one share of the Company’s common stock, par value $.0001 per
share (“Common Stock”), and one warrant exercisable for one share of Common Stock (“Warrant”) and embarking on the IPO process, hereby agrees as follows (certain capitalized terms used herein are defined in Schedule 1 hereto):

 1. If the Company solicits approval of its stockholders of a Business Combination, the undersigned shall (i) vote all Insider Shares
owned by such person in accordance with the majority of the votes cast by the holders of the IPO Shares and (ii) vote any shares of Common Stock acquired following or in the IPO in favor of the Business Combination, as a result of which the
undersigned acknowledges and agrees that it will not be entitled to exercise the conversion rights offered to the Company’s public stockholders as to any Insider Shares or other shares of Common Stock owned by it. 
 2. If a Transaction Failure occurs, the undersigned shall take all reasonable actions within such person’s power to cause (i) the Trust Fund to
be liquidated and distributed to the holders of the IPO shares as soon as reasonably practicable and in any event no later than the Termination Date, and (ii) the Company to dissolve and liquidate as soon as practicable (the earliest date on
which the conditions in clauses (i) and (ii) are both satisfied being the “Liquidation Date”). The undersigned hereby waives any and all right, title, interest or claim of any kind in or to any liquidating distributions by the
Company and hereby further 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 agrees to not seek recourse against the Trust Fund for any reason whatsoever. The
undersigned hereby agrees that the Company shall be entitled to a reimbursement from the undersigned for any distribution of the Trust Fund received by the undersigned in respect of such person’s Insider Shares. The undersigned agrees to
indemnify and hold harmless the Company, pro rata with the other officers and directors of the Company based on the number of Insider Shares held by each such individual, against any and all loss, liability, claims, 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, or any claim whatsoever) which the Company may become subject as
a result of any claim by any vendor or other person that is owed money by the Company for services rendered or products sold but only to the extent necessary to ensure that such loss, liability, claim, damage or expense does not reduce the amount in
the Trust Fund. 
 3. In order to minimize potential conflicts of interest which may arise from multiple affiliations, the undersigned agrees
to present to the Company for its consideration, prior to the undersigned’s exploitation of that opportunity in any way or the presentation to any other person or entity, any suitable opportunity to acquire all or substantially all of the
outstanding equity securities of, or otherwise acquire (through merger, capital stock exchange, asset acquisition, stock purchase or other business combination) an operating business in the homebuilding industry until the earlier of the consummation
by the Company of a Business Combination, the distribution of the Trust Fund or until such time as the undersigned ceases to be an officer or director of the Company; provided, however, that the presentation of such opportunities to the
Company shall in each case be subject to any pre-existing fiduciary and/or contractual obligations the undersigned might have.

representing an allocable share of Related Party’s overhead, to compensate it for the Company’s use of Related Party’s offices, utilities and personnel. The Related Party and the undersigned shall also be entitled to reimbursement
from the Company for their reasonable out-of-pocket expenses incurred in connection with seeking and consummating a Business Combination. 
 6. The undersigned agrees that neither the undersigned, any member of the Immediate Family of the undersigned, or any Affiliate of the undersigned will be entitled to receive or accept, and the undersigned, on behalf of the undersigned and
the aforementioned parties, hereby waives any rights to, a finder’s fee or any other compensation in the event the undersigned, any member of the Immediate Family of the undersigned or any Affiliate of the undersigned originates a Business
Combination.

and an escrow agent acceptable to the Company, escrow his Insider Shares for the period commencing on the Effective Date and ending on the earlier of (i) one year from the date of the Business Combination,, (ii) the date on which the
Company gives the escrow agent notice that the Company is being liquidated at which time the escrow agent will destroy the shares, or (iii) in the event the Company undertakes a Business Combination, at such a time when the escrow agent
releases the Insider Shares in order for the undersigned to participate in a Business Combination in which all shareholders have the right to exchange their shares of Common Stock for other property. 
 8. The undersigned agrees to be the Chairman, Chief Executive Officer, President and a member of the Board of Directors of the Company until the earlier
