This
Convertible Promissory Note and Loan Agreement is made and entered into as of June 14, 2016 by and between Entera Bio Ltd., a
company organized under the laws of the State of Israel (the “Company”),
and [___________________] (the “Lender”), and is one of a series of Convertible Promissory Note and Loan Agreements
entered into as of the date hereof by the Company and the other parties thereto (such other parties together with the Lender,
the “Lender Group”),
totaling an aggregate amount of $5.5 million (and together with the Corundum Note an aggregate amount of $6.5 million). Commencing
from the date of the Closing and until 90 days from the date of the Closing, the Company may raise an additional amount of up
to 0.5 million, in one or more additional closing(s), under the terms of this Convertible Promissory Note from certain lenders,
as shall be determined at the sole discretion of the Board.


 


For
good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto, intending to
be legally bound, hereby agree as follows:


 


1.                 
The Loan. Subject to the terms and conditions of this Agreement, at
the Closing (as defined below), the Lender shall lend (the “Loan”)
to the Company the aggregate principal amount of [___] (the “Principal Amount”). Subject to the fulfillment or waiver
of the conditions set forth in Section 10 hereof, the closing of the Loan (“Closing”)
shall take place simultaneously upon the execution and delivery by the Lender and the Company of this Note. The Lender shall pay
the Principal Amount to the Company, by wire transfer to the Company’s bank account designated by the Company to the Lender.
The Principal Amount together with all accrued interest (together, the “Loan Obligations”) shall be pari passu to
all principal and other amounts outstanding under those certain (i) Convertible Financing Agreements entered into by the Company
with the other parties thereto (cumulatively, the “Convertible Financing Agreements”) in the  total principal
amounts of $1.15 million as described in Note 7 to the Company’s financial statements for the fiscal year ended December
31, 2014, (ii) Convertible Promissory Note and Loan Agreement entered into by the Company with the other parties thereto in the
total principal amounts of $2.005 million dated August 5, 2015 (the “Original
Convertible Notes”) and (iii) the Convertible Promissory Note and Loan Agreements entered into by the Company
and Corundum Open Innovation Fund, L.P. (“Corundum”),
dated as of the date hereof (the “Corundum
Note”, and together with the Convertible Financing Agreements and the Original Convertible Notes, the “Prior
Notes”).


 


At
the execution of this Agreement, the Company shall deliver to the Lender (i)


 






     


     

    

 


(i)  
a copy of the resolution of the Company’s board of directors (“Board”),
duly approving this Agreement, the Warrant and all the transactions contemplated hereby; (ii) a copy of the resolution of the
shareholders of the Company (x) duly approving the transactions contemplated hereby; (y) amending Article 38(i) of the Fourth
Amended Articles of Association such that the Board will include one additional director to be nominated by Pontifax, on behalf
of the Lender Group as long as the Loan Obligations have not been converted or repaid in full pursuant to the terms of this Note,
provided that following the conversion of this Note into equity securities of the Company in accordance with the terms of this
Note, the Lender Group shall be entitled to appoint one director for so long as it holds one percent (1%) or more of the issued
and outstanding share capital of the Company on a fully-diluted and as-converted basis. The abovementioned right to appoint a
director shall terminate immediately prior to and subject to the closing of the IPO by the Company. In the event of any 30 day
uncured default of payment by the Company under the terms of this Note or any of the Prior Notes, then the holders of a majority
of principal amounts of the Lender Group shall be entitled to nominate, upon written notice to the Company, that number of Board
members to the Board of Directors of the Company determined by multiplying the total number of Board members by a fraction, the
numerator of which shall be the aggregate principal amount of the Lender Group Notes then outstanding and the denominator of which
shall equal the aggregate principal amount of the Lender Group then outstanding plus the principal amount of the Prior Notes then
outstanding; (iii) confirmation by the Company’s CEO that the Company has executed (a) identical convertible promissory
notes (including this Note) with the Lender Group in the aggregate amount equal to $5.5 million or more, and (b) the Corundum
Note with Corundum in the aggregate amount of 1.0 million; and (iv) establishment of an escrow account to be used for the repayment
in full of the outstanding principal amount plus any interest owed at maturity under the Original Convertible Notes (the “Escrowed
Funds”). The Company may convert any or the entire outstanding amounts under the Original Convertible Notes (which for the
avoidance of doubt, shall include the interest accrued thereon as of such time) into the Lender Group Notes at the Closing or
for a period of 15 days following the Closing and the amount of Escrowed Funds will be reduced by the amount of such Original
Convertible Notes that convert into Lender Group Notes with such reduced amount released to the Company for general corporate
purpose use.


 


2.               
Interest. Interest shall accrue on the Principal Amount from the Issue
Date through the Maturity Date at the rate of five percent (5%) per annum. Interest shall be calculated on the basis of the actual
number of days elapsed over a 365-day year. The Loan shall be subject to the היתר עסקה
publicized on http://www.keter.org.il/.


 


3.               
Maturity Date. Unless earlier converted pursuant to Sections 4 or 5
below, the Loan Obligations shall be due and payable in full on December 14, 2017 (“Maturity
Date”), provided, however,
that upon the earlier to occur of (i) maturity of the Original Convertible Notes where the Company is using any of
the Company’s funds in excess of the Escrowed Funds for the payment of principal and interest on the Original Convertible
Notes; or (ii) acceleration of any of the Original Convertible Notes including as a result of the occurrence of an event of default
pursuant to their terms or trigger of an “Insolvency Event” (as defined below), the Loan Obligations shall become

9.     
Representations and Warranties of the Lender.


 


By
the acceptance of this Note, the Lender represents and warrants to the Company that:


 


(a)  
The Lender is acquiring this Note and the Warrant for Lender’s own account for investment and not with a view to
or for sale in connection with any distribution, and all Securities will also be acquired for Lender’s own account, for
investment and not with a view to, or for sale in connection with any distribution.


 


(b)  
The Lender was contacted directly by the Company and/or its representatives regarding engaging in the transactions contemplated
by this Note and the Warrant or a similar financing transaction with the Company, and was not initially notified about the Company
or a potential transaction with the Company via any public announcement or publication regarding an intended public offering of
the Company's securities.


 


(c)  
The Lender understands that the Securities and the Warrant may not be sold, transferred, assigned, pledged, or otherwise
disposed of unless the Securities or the Warrant (as applicable) are registered under the Act, and all applicable state securities
laws or unless exemptions from such registration requirements are available.


 


(d)  
The Lender is an experienced investor in securities of companies in an early development stage and acknowledges that it
is able to fend for itself, can bear the economic risks of such investment (including the complete loss thereof) and has such
knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of this investment.
The Lender has been afforded the opportunity to ask questions to officers or other representatives of the Company concerning the
business of the Company, and it has reviewed and inspected all of the data and information provided to it by the Company in connection
with this Note. The Lender is (i) an “accredited investor” within the meaning of Rule 501 of Regulation D promulgated
under the Act and/or (ii) a non-“U.S. person” within the meaning of Rule 902(k) promulgated under the Securities Act
(and the Lender is not engaging in the transactions hereunder for the account or benefit of a U.S. Person) and at the time of
the offer and sale of the Note and the Warrant the Lender was not located in the United States.

(e)  
The Lender understands that any permitted successor holder or transferee of the Securities will be required to provide
to the Company the representations and warranties contained in this Section 9.


 


(f)   
The Lender understands that the Securities and the Warrant have not been, and will not be, registered under the Act, or
any state securities law, based on an exemption or exemptions provided thereunder, the availability of which depends upon, among
other things, the bona fide nature of the investment intent and the accuracy of such Lender’s representations as expressed
herein, and will be “restricted securities” within the meaning of Rule 144 promulgated under the Act; and that all
stock certificates representing Securities may have affixed thereto a legend substantially in the following form.

SECURITIES REPRESENTED HEREBY HAVE NOT BEEN


 


REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”) OR ANY STATE SECURITIES LAWS, AND MAY NOT BE SOLD, OFFERED
FOR SALE, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR UNLESS SUCH
TRANSFER IS EXEMPT FROM THE REGISTRATION REQUIREMENTS OF THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS. THE COMPANY MAY REQUIRE
AN OPINION OF COUNSEL, IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE COMPANY, TO THE EFFECT THAT REGISTRATION IS NOT REQUIRED
IN CONNECTION WITH SUCH TRANSFER.


 


10.            
Conditions to the Parties’ Obligations. The obligations of the
Lender and the Company under this Agreement are subject to the fulfillment of each of the following conditions, at or before the
Closing, unless otherwise waived by the parties hereto, as applicable:


 


(a)  
Waivers of Pre-emptive Rights. Any pre-emptive or other participation
rights of any person other than the Lender to participate in the lending of such Lender's Loan and in the issuances of the Company’s
Securities upon conversion of the Principal Amount and accrued interest and in the issuance of the Company's Securities upon execution
of the Warrant, as may exist pursuant to the Articles or any other agreements between the Company and its shareholders, shall

shall use its reasonable efforts to reincorporate within a jurisdiction in the United States (the “Reincorporation”),
which such reincorporation may be effected pursuant to a merger of the Company with an affiliated entity of the Company that is
incorporated in the United States following which such affiliated entity would hold all the outstanding shares of the Company,
and the Lender agrees to exchange this Note and the Warrant being issued in connection herewith for a note and warrant to be issued
on substantially the same terms and conditions hereof and thereof to be issued by the U.S. entity following the Reincorporation.


 






    10 


     

    

 


12.

an effective registration statement filed with the Securities and Exchange Commission under the Act covering the disposition or
sale of this Note or the Securities, as the case may be, and registration or qualification under applicable state securities laws,
the Lender will not Transfer any or all of this Note or the Securities, as the case may be, unless such Transfer is exempt from

Company will have authorized and reserved for the purpose of the issue upon conversion of this Note and/or the Warrant, as applicable,
a sufficient number of Securities to provide for the conversion of this Note and Warrant and, in the event that the Applicable
Securities are convertible preferred shares, a sufficient number of Ordinary Shares of the Company to provide for the conversion
of the Applicable Securities into Ordinary Shares of the Company.


 


14.           
Taxes; Withholding. Any taxes, fees, levies, duties, surcharges or

with a certificate evidencing any valid exemption from such deduction or withholding. Any value added tax to be paid by the Company
in connection with the transactions hereunder (including but not limited to payment of any interest due hereunder) shall be paid
by the Company upon receipt of a valid value added tax invoice.

all documentation, information and/or other materials provided to the members of the Board and in addition the Observer shall

materials and discussions confidential and will not disclose or divulge such materials and discussions to any third party. Notwithstanding
the above, the Company shall not be obligated to provide access to any information or meeting of the Board that will impair attorney-client

by the Board, acting in good faith.
