THIS PRIVATE PLACEMENT WARRANTS PURCHASE AGREEMENT
(as it may from time to time be amended and including all exhibits referenced herein, this “Agreement”), dated as of
[●], 2021, is entered into by and among Arbor Rapha Capital Bioholdings Corp. I, a Delaware corporation (the “Company”),
and Arbor Rapha Capital LLC, a Delaware limited liability company (the “Purchaser”).


 


WHEREAS, the Company intends to consummate an initial
public offering of the Company’s units (the “Public Offering”), each unit consisting of one share of Class A
common stock of the Company, par value $0.0001 per share (each, a “Share”), and one-third of one redeemable warrant,

Act”).


 


WHEREAS, the Purchaser has agreed to purchase,
at a price of $1.50 per warrant, an aggregate of 3,833,333 warrants (and up to 300,000 additional warrants if the underwriters in the
Public Offering exercise their over-allotment option in full) (the “Private Placement Warrants”), each Private Placement
Warrant entitling the holder to purchase one Share at an exercise price of $11.50 per Share.


 


NOW THEREFORE, in consideration of the mutual promises
contained in this Agreement and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties to this Agreement hereby, intending legally to be bound, agree as follows:

Warrants in proportion to the portion of the overallotment option that is exercised) at a price of $1.50 per Private Placement Warrant
for an aggregate purchase price of up to $450,000 (if the over-allotment option is exercised in full) (the “Over-allotment
Purchase Price”). The Purchaser shall pay the Over-allotment Purchase Price in accordance with the Company’s wire
instruction by wire transfer of immediately available funds, at least one (1) business day prior to the applicable Over-allotment Closing
Date. On each Over-allotment Closing Date, upon the payment by the Purchaser of the Over-allotment Purchase Price by wire transfer of

purchased on such date duly registered in the Purchaser’s name to the Purchaser or effect such delivery in book-entry form.


 


C.             
Terms of the Private Placement Warrants.

Company will grant certain registration rights to the Purchaser relating to the Private Placement Warrants and the Shares underlying the
Private Placement Warrants.


 


Section 2. Representations
and Warranties of the Company.


 


As a material inducement to the Purchaser to enter
into this Agreement and purchase the Private Placement Warrants, the Company hereby represents and warrants to the Purchaser (which representations
and warranties shall survive each Closing Date) that:


 


A.             
Incorporation and Corporate Power. The Company is a corporation duly incorporated, validly existing and in good standing
under the laws of the State of Delaware and is qualified to do business in every jurisdiction in which the failure to so qualify would

with its terms, subject to bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other laws of general applicability
relating to or affecting creditors’ rights and to general equitable principles (whether considered in a proceeding in equity or
law). Upon issuance in accordance with, and payment pursuant to, the terms of the Warrant Agreement and this Agreement, the Private Placement
Warrants will constitute valid and binding obligations of the Company, enforceable in accordance with their terms as of each Closing Date.


 


(ii)              The
execution and delivery by the Company of this Agreement and the Private Placement Warrants, the issuance and sale of the Private
Placement Warrants, the issuance of the Shares upon exercise of the Private Placement Warrants and the fulfillment of and compliance

date hereof or as may be amended prior to completion of the Public Offering) or any material law, statute, rule or regulation to

or provisions of, (b) constitute a default under, (c) result in the creation of any lien, security interest, charge or encumbrance upon

Public Offering, or any material law, statute, rule or regulation to which the Purchaser is subject, or any agreement, instrument, order,
judgment or decree to which the Purchaser is subject, except for any filings required after the date hereof under federal or state securities
laws.


 


C.              
Investment Representations.


 


(i)                The Purchaser is acquiring the Private Placement Warrants and, upon exercise of the Private Placement Warrants, the Shares issuable
upon such exercise (collectively, the “Securities”) for its own account, for
investment purposes only and not with a view towards, or for resale in connection with, any public sale or distribution thereof.


 


(ii)              
The Purchaser is an “accredited investor” as such term is defined in Rule 501(a)(3) of Regulation D under the Securities
Act.


 


(iii)            
The Purchaser has not experienced a disqualifying event as enumerated pursuant to Rule 506(d) of Regulation D under the Securities
Act.


 


(iv)            
The Purchaser understands that the Securities are being offered and will be sold to it in reliance on specific exemptions from
the registration requirements of the United States federal and state securities laws and that the Company is relying upon the truth and
accuracy of, and the Purchaser’s compliance with, the representations and warranties of the Purchaser set forth herein in order
to determine the availability of such exemptions and the eligibility of the Purchaser to acquire such Securities.


 


(v)              The
Purchaser did not decide to enter into this Agreement as a result of any general solicitation or general advertising within the meaning
of Rule 502(c) of Regulation D under the Securities Act.


 


(vi)            
The Purchaser has been furnished with all materials relating to the business, finances and operations of the Company and materials
relating to the offer and sale of the Securities which have been requested by the Purchaser. The Purchaser has been afforded the opportunity
to ask questions of the executive officers and directors of the Company. The Purchaser understands that its investment in the Securities
involves a high degree of risk and it has sought such accounting, legal and tax advice as it has considered necessary to make an informed
investment decision with respect to the acquisition of the Securities.


 






    5


     


    

 


(vii)           
 The Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed
on or made any recommendation or endorsement of the Securities or the fairness or suitability of the investment in the Securities by the
Purchaser nor have such authorities passed upon or endorsed the merits of the offering of the Securities.


 


(viii)          
The Purchaser understands that: (a) the Securities have not been and are not being registered under the Securities Act or any state
securities laws, and may not be offered for sale, sold, assigned or transferred unless (1) subsequently registered thereunder or (2) sold
in reliance on an exemption therefrom; and (b) except as specifically set forth in the Registration and Stockholder Rights Agreement,
neither the Company nor any other person is under any obligation to register the Securities under the Securities Act or any state securities
laws or to comply with the terms and conditions of any exemption thereunder. In this regard, the Purchaser understands that the SEC has
taken the position that promoters or affiliates of a blank check company and their transferees, both before and after the Company’s
initial Business Combination, are deemed to be “underwriters” under the Securities Act when reselling the securities of a
blank check company. Based on that position, Rule 144 adopted pursuant to the Securities Act would not be available for resale transactions
of the Securities despite technical compliance with the requirements of such Rule 144, and the Securities can be resold only through a
registered offering or in reliance upon another exemption from the registration requirements of the Securities Act.


 


(ix)             
The Purchaser has such knowledge and experience in financial and business matters, knowledge of the high degree of risk associated
with investments in the securities of companies in the development stage such as the Company, is capable of evaluating the merits and
risks of an investment in the Securities and is able to bear the economic risk of an investment in the Securities in the amount contemplated
hereunder for an indefinite period of time. The Purchaser has adequate means of providing for its current financial needs and contingencies
and will have no current or anticipated future needs for liquidity which would be jeopardized by the investment in the Securities. The
Purchaser can afford a complete loss of its investments in the Securities.


 


(x)              
The Purchaser understands that the Private Placement Warrants shall bear the legend substantially in the form set forth in the
Warrant Agreement and be subject to appropriate “stop transfer restrictions”.
