BIOSCIENCES, inc., a corporation incorporated under the laws of the Commonwealth of Massachusetts and located at 14
Norfolk Avenue, South Easton, MA 02375 (the “Company”), in favor of XXXXXXX, an individual residing at XXXXX
(the “Holder”).


 


FOR
VALUE RECEIVED, the Company promises to pay to the order of the Holder the principal sum of Two Million United States Dollars
(US$2,000,000) (the “Principal Amount”) or, if less, the aggregate unpaid principal amount of the Revolver
Advances (as defined below) from time to time outstanding made by the Holder to the Company, by the twelve (12) month anniversary
of the date hereof, or such earlier date, pursuant to Section 3 hereof (the “Maturity Date”), and to pay interest
in an amount equal to the Guaranteed Interest (as defined below) on all outstanding amounts hereunder on or prior to the Maturity
Date, in accordance with the terms hereof.


 






    	 		 



    	 		 



    

 


1.
Principal and Interest.


 


(a)
Revolver Advances. The Company shall request principal advances from time to time prior to the Maturity Date by delivering
an advance request (in the form attached hereto as Exhibit A, each an “Advance Request”) to the Holder.
Within three (3) Business Days of the Holder’s receipt of an Advance Request, the Holder shall advance a principal amount
to Signature Bank acting as escrow agent for the Company equal to the amount requested by the Company on the relevant Advance
Request, provided, however, that (a) the Holder agrees to make the requested principal advance to the Company; (b)
at no time shall the principal amount outstanding hereunder exceed the Principal Amount; (c) the Company shall not request and
the Holder shall not be required to advance more than $250,000 in any individual fifteen (15) day period; and (d) the Company
shall not request and the Holder shall not be required to advance more than $500,000 in the thirty (30) day period immediately
following the date of the initial advance hereunder. Upon advancing any principal amount to the Company pursuant hereto, the Holder
shall endorse the amount and the date of the making of the principal advance hereunder on the grid annexed hereto as Schedule
A and made a part hereof (the “Payment Schedule”), which endorsement shall, absent gross negligence, constitute
evidence of the accuracy of the information so endorsed; provided, however, that any failure to endorse such information
on the Payment Schedule shall not in any manner affect the obligation of the Company to make payment of principal and interest
in accordance with the terms of this Note. The release of funds shall be determined by the receipt of an executed Advance Request
by the Company and the Investor (“Closing Conditions”). Once Closing Conditions have been satisfied, the Company
and Garden State Securities, Inc. will instruct the escrow agent to release funds from escrow.


 


(b)
Payment of Principal. The principal amount of this Note shall be paid in full on the Maturity Date, unless otherwise paid
prior to the Maturity Date, at the option of the Company.


 


(c)
Payment of Interest. Interest on the principal balance of this Note shall paid in full on the Maturity Date, unless otherwise
paid prior to the Maturity Date, at the option of the Company. With the exception of Default Interest, interest shall be in the
form of one-time interest charges assessed in full as of the date of the principal advance and shall not be assessed per annum.
The amount of interest which shall be assessed with respect to any principal advance shall be determined as follows (the “Guaranteed
Interest”):


 


	 	i.	one-time
    interest charge of ten percent (10%) on all principal amounts advanced on or prior to the six (6) month anniversary of the
    date hereof (such date, the “Trigger Date”);
	 	 	 
	 	ii.	one-time
    interest charge of ten percent (10%) on (1) all principal amounts advanced following the Trigger Date and prior to the nine
    (9) month anniversary of the date hereof and, (2) with respect to any amounts which have been previously advanced prior to
    the Trigger Date and remain outstanding as of the Trigger Date, four percent (4%) on all such outstanding principal amounts,
    as determined to be outstanding as of the Trigger Date; and
	 	 	 
	 	iii.	one-time
    interest charge of ten percent (10%) on (1) all principal amounts advanced following the nine (9) month anniversary of the
    date hereof and prior to the Maturity Date and, (2) with respect to any amounts which have been previously advanced prior
    to the nine (9) month anniversary of the date hereof and remain outstanding as of the nine (9) month anniversary of the date
    hereof, four percent (4%) on all such outstanding principal amounts, as determined to be outstanding as of the nine (9) month
    anniversary of the date hereof.


 






    	 	2	 



    	 		 



    

 


(d)
Payment of Default Interest. Any amount of principal or interest on this Note which is not paid when due shall bear interest
at the rate of twenty percent (20%) per annum (the “Default Rate”) until such past due amount is paid.


 


(e)
General Payment Provisions. All payments of principal and interest on this Note shall be made in lawful money of the United
States of America by check or wire transfer to such account as the Holder or the Company (as applicable) may designate. Whenever
any amount expressed to be due by the terms of this Note is due on any day which is not a Business Day, the same shall instead
be due on the next succeeding Business Day. For purposes of this Note, “Business Day” shall mean any day other
than a Saturday, Sunday or a day on which commercial banks in the State of New York are authorized or required by law or executive
order to remain closed.


 


2.
Repayments/Prepayments/Re-Borrowing. The Company may from time to time, repay or prepay the outstanding balance owed pursuant
to this Note, in whole or in part, without penalty. The Holder shall endorse the amount and the date of any repayment or prepayment
on the Payment Schedule, which endorsement shall, absent gross negligence, constitute evidence of the accuracy of the information
so endorsed; provided, however, that any failure to endorse such information on the Payment Schedule shall not in
any manner affect the obligation of the Borrower to make payment of principal and interest in accordance with the terms of this
Note. Any amount repaid or prepaid hereunder may be re-borrowed at the option of the Company.


 


3.
Acceleration of Maturity Date. In the event that the Company completes a Qualified Offering, the Company shall repay any
and all amounts owing to the Holder pursuant hereto within seven (7) Business Days of the closing date of such Qualified Offering.
“Qualified Offering” means the completion of a public offering of the Company’s securities pursuant to
which the Company receives aggregate gross proceeds of at least Seven Million United States Dollars (US$7,000,000) in consideration
of the purchase of its securities and resulting in, pursuant to the effectiveness of the registration statement for such offering,
the Company’s common stock being traded on the NASDAQ Capital Market, NASDAQ Global Select Market or the New York Stock
Exchange. 


 


4.
Qualified Offering. While any principal or interest remains outstanding hereunder, the Holder has the right to convert
all or any portion of the outstanding principal or interest into common stock of the Company on the same terms and for the same
purchase price as the Company has offered, and third party investors have accepted, in connection with the Qualified Offering.

(c)
Information on Holder. Holder is an “accredited investor,” as such term is defined in Regulation D promulgated
by the Commission under the 1933 Act, is experienced in investments and business matters, has made investments of a speculative
nature and has purchased securities of United States publicly-owned companies in private placements in the past and, with Holder’s
representatives, has such knowledge and experience in financial, tax and other business matters as to enable Holder to utilize
the information made available by the Company to evaluate the merits and risks of, and to make an informed investment decision
with respect to, the proposed purchase, which Holder hereby agrees represents a speculative investment. Holder has the authority
and is duly and legally qualified to purchase and own the Note. Holder is able to bear the risk of such investment for an indefinite
period and to afford a complete loss thereof.

Purchase of Note. Holder will purchase the Note for Holder’s own account for investment and not with a view toward,
or for resale in connection with, the public sale or any distribution thereof in violation of the Securities Act of 1933, as amended

understandings with any other person or entity to distribute or regarding the distribution of the Note.

Highly Speculative Investment. Holder acknowledges and agrees that a purchase of the Note is highly speculative and involves
significant risks and that the Note should not be purchased if Holder cannot afford the loss of Holder’s entire investment.
The business objectives of the Company are speculative, and it is possible that the Company may be unable to achieve them. Holder
understands that Holder may be unable to realize a substantial return on the purchase of the offered Note, or any return whatsoever,
and may lose Holder’s entire investment.

or any other form of general advertising or solicited or invited to attend a promotional meeting otherwise than in connection
and concurrently with such communicated offer.


 


(h)
No Governmental Endorsement. Holder understands that no United States federal or state agency or any other governmental

Note, nor have such authorities passed upon or endorsed the merits of the offering of the Note.


 


(i)
Information. Holder and its advisors, if any, have 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 Note that have been requested by Holder. Holder
and its advisors, if any, have been afforded the opportunity to ask questions of the Company. Neither such inquiries nor any other
due diligence investigations conducted by Holder or its advisors, if any, or its representatives shall modify, amend or affect
Holder’s right to rely on the Company’s representations and warranties contained herein. Holder understands that its
investment in the Note involves a high degree of risk and the Holder is able to afford a complete loss of such investment. Holder
has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect
to its acquisition of the Note.
