FOR
VALUE RECEIVED, OPTMED, INC., a Delaware corporation (the “Company”), located at 5745 Fifth Avenue, Suite 500, New York,
NY 10151, promises to pay to _________________________, or any subsequent holder upon permitted assignment of this Note (the “Holder”),
at ________________________________, or at such other location as the Holder may designate from time to time in a written notice provided
to the Company, the principal sum of $             (        U.S. Dollars) together with interest thereon from the date of this Note. Interest shall accrue
at a rate of eight percent (8.0%) per annum, simple interest. Interest shall be computed on the basis of a 365-day year, for the actual
days elapsed. Unless earlier converted into Equity Securities pursuant to the terms of this Note or paid in full in accordance with the
terms hereof, the principal and accrued interest shall be due and payable by Company on demand by the Requisite Holders (as defined below)
at any time after the earlier of: (i)            , 2022 (“Maturity Date”), and (ii) an Event of Default (as defined below).

 

This
Convertible Promissory Note (this “Note”) is one in a series of substantially identical (other than as to date of
issuance, principal amount and identity of the holder thereof) convertible promissory notes (collectively, the “Notes”)
with the same discount rate, issued by the Company in the aggregate principal amount of up to $1,000,000; provided, however, that upon
the receipt of the written approval of the holders of a majority of the aggregate principal amount of all then-outstanding Notes (collectively,
the “Requisite Holders”), the Board of Directors of the Company may increase the maximum principal amount of such
Notes issuable by the Company. The Notes rank pari passu in right of payment, and all payments on the Notes shall be paid to the
holders thereof pro-rata based on the respective principal balances of the Notes.

 

1.
Definitions.

 

(a)
“Applicable Discount” means 25%.

 

(b)
“Common Stock” means the Company’s common stock, $0.0001 par value per share.

 

    	 

     

    

 

(c)
“Conversion Shares” (for purposes of determining the type of Equity Securities issuable upon conversion of the Notes)
means with respect to a conversion pursuant to Section 3(a), shares of the Equity Securities issued in the Qualified Equity Financing.

 

(d)
“Conversion Price” means (rounded to the nearest 1/100th of one cent) with respect to a conversion pursuant to Section
3(a), the product of (x) 100% less the Applicable Discount and (y) the per share purchase price of the Equity Securities issued
in the Qualified Financing;

 

(e)
“Corporate Transaction” means:

 

(i)
a sale of all or substantially all of the Company’s assets other than to an Excluded Entity;

company or other entity other than an Excluded Entity pursuant to which stockholders of the Company prior to such merger, consolidation
or other capital reorganization or business combination transaction own less than fifty percent (50%) of the voting interests in the
surviving or resulting entity; or

For
the avoidance of doubt, a transaction will not constitute a “Corporate Transaction” if its sole purpose is to change the
state of the Company’s incorporation or to create a holding company that will be owned in substantially the same proportions by
the persons who held the Company’s securities immediately prior to such transaction. Notwithstanding the foregoing, the sale of
Equity Securities in a bona fide financing transaction will not be deemed a “Corporate Transaction.”

any securities directly or indirectly convertible into, or exchangeable for (with or without additional consideration) Common Stock.

or sold by the Company to any director, officer, employee, consultant or adviser of the Company for the primary purpose of soliciting
or retaining their services; and (ii) any convertible promissory notes or other similar convertible instruments (including the Notes)
issued by the Company.

 

(g)
“Event of Default” means (a) the Company fails to make any payment under the Notes when due; (b) a receiver is appointed
for any material part of the Company’s property, the Company makes a general assignment for the benefit of creditors, or the Company

proceeding for the general adjustment of its debts or for its liquidation; (c) the Company breaches any of its material obligations under
the Notes and does not cure such breach within 20 days after written notice thereof to the Company; and (d) the Company’s Board
of Directors or stockholders adopt a resolution for the liquidation, dissolution or winding up of the Company.

 

(h)
“Exchange Act” means the Securities Exchange Act of 1934, as amended.

 

(i)
“Excluded Entity” means a corporation or other entity of which the holders of voting capital stock of the Company
outstanding immediately prior to such transaction are the direct or indirect holders of voting securities representing at least a majority
of the votes entitled to be cast by all of such corporation’s or other entity’s voting securities outstanding immediately
after such transaction.

hereafter created.

 

(k)
“Qualified Equity Financing” means the next sale (or series of related sales) by the Company of its Preferred Stock

amended, resulting in at least $10,000,000 of aggregate proceeds, net of the underwriting discount and commissions, to the Company, or
(b) any other firm-commitment underwritten public offering of shares of Common Stock pursuant to which all outstanding shares of the
Company’s Preferred Stock convert into Common Stock in accordance with the terms of the Company’s Certificate of Incorporation,
as amended and/or restated from time to time.

 

2.
Payment. Except in connection with the conversion of principal and unpaid accrued interest hereunder into Equity Securities as
provided for herein, (i) all payments shall be made in lawful money of the United States of America at the principal office of the Company,
or at such other place as the holder hereof may from time to time designate in writing to the Company; and (ii) payment shall be credited
first to accrued interest due and payable and the remainder applied to principal. Prepayment of principal or interest may not be made
without the prior written consent of the Requisite Holders, except in the event of a Corporation Transaction, and any prepayment of this
Note shall be made only in connection with the pro rata prepayment of all outstanding Notes, with any such prepayment applied first to
the payment of accrued interest and the remainder, if any, applied to principal.

 

3.
Conversion of the Note; Treatment of Note upon Corporate Transaction.

 

(a)
Qualified Financing. The principal balance and unpaid accrued interest on this Note will automatically convert into Conversion
Shares upon the closing of a Qualified Financing. The number of Conversion Shares the Company issues upon such conversion will equal
the quotient (rounded down to the nearest whole share) obtained by dividing (x) the outstanding principal balance and unpaid accrued
interest under this Note on a date set by the Company that is no more than five (5) days prior to the closing of the Qualified Financing
by (y) the Conversion Price. At least five (5) days prior to the closing of the Qualified Financing, the Company will notify the holder
of each Note in writing of the terms of the Equity Securities that are expected to be issued in such financing. The issuance of Conversion
Shares pursuant to the conversion of each Note will be on, and subject to, the same terms and conditions applicable to the Equity Securities
issued in the Qualified Financing. If a transaction fails to qualify as a “Qualified Equity Financing” solely because it
results in proceeds to the Company of less than the requisite amount, each holder of a Note may, in its discretion, choose to treat such
financing as if it were a Qualified Equity Financing and convert its Note into such financing.

 

(b)
Corporate Transaction. In the event of a Corporate Transaction prior to the conversion of a Note pursuant to Section 3(a) or the
repayment of this Note, at the closing of such Corporate Transaction, the Company will pay the Holder an amount equal to the sum of (i)
1.25 times the outstanding principal amount of such Note, and (ii) all accrued and unpaid interest on such Note immediately prior to
such Corporate Transaction.

 

    	3

     

    

 

(c)
Mechanics of Conversion.

 

(i)
Holder acknowledges that the conversion of the Notes into Conversion Shares pursuant to Section 3(a) may require Holder’s
execution of certain agreements relating to the purchase and sale of the Conversion Shares, as well as, in the case of conversion upon
a Qualified Equity Financing, registration rights, rights of first refusal and co-sale, rights of first offer and voting rights, if any,
relating to such securities (collectively, the “Financing Agreements”). Holder agrees to execute all of the Financing
Agreements in connection with a Qualified Financing.

 

(ii)
As promptly as practicable after the conversion of this Note and the issuance of the Conversion Shares, the Company (at its expense)
will issue and deliver to the Holder a certificate or certificates evidencing the Conversion Shares (if certificated), or if the Conversion
Shares are not certificated, will deliver a true and correct copy of the Company’s share register reflecting the Conversion Shares
held by such holder; provided that Conversion Shares issued in connection with a Qualified Initial Public Offering shall be represented
in electronic, book-entry position in the name of the Holder or its nominee. The Company will not be required to issue or deliver the
Conversion Shares until the Holder has surrendered the Note to the Company (or provided an instrument of cancellation or affidavit of
loss). The conversion of the Notes pursuant to Section 3(a) may be made contingent upon the closing of the Qualified Financing.

 

(d)
Amendment of Certificate of Incorporation. The Company shall not be obligated to effect any amendment to its Certificate of Incorporation
to authorize the shares of the Company’s capital stock that are issuable upon conversion of this Note until immediately prior to
the effectiveness of such conversion.

 

4.
Events of Defaults and Remedies. Subject to the provisions of Section 6, upon the occurrence of an Event of Default, at the option
and upon the declaration of the Requisite Holders, the entire unpaid principal and accrued and unpaid interest on the Notes shall, without
presentment, demand, protest, or notice of any kind, all of which are hereby expressly waived, be forthwith due and payable, and the
Holder may, immediately and without expiration of any period of grace, enforce payment of all amounts due and owing under such Note and
exercise any and all other remedies granted to it at law, in equity or otherwise. The Company shall promptly notify the Holder of the
occurrence of any Event of Default.

 

5.
Security. This Note is a general unsecured obligation of the Company.

 

6.
Priority and Subordination. This Note is subordinated in right of payment to all indebtedness of the Company to H.B. Fuller Company
and Pidilite USA, Inc. or their respective successors and assigns (the “Senior Creditors”) for borrowed funds and
for all expenses and costs owing to the Senior Creditors under such indebtedness (the “Senior Debt”). The Company
hereby agrees, and by accepting this Note, the Holder hereby acknowledges and agrees, that so long as any Senior Debt is outstanding
and until the same is paid in full, the Company will not make, and the Holder will not receive or retain, any payment under this Note
whatsoever (other than the receipt of shares upon the conversion of this Note). In addition, until the Senior Debt has been indefeasibly
paid in full, if an Event of Default has occurred and is continuing under this Note, the Holder will not commence or join with any creditor
of the Company in asserting or commencing any proceedings to collect or enforce its rights hereunder or take any action to foreclose,
accelerate, or realize upon the indebtedness hereunder or declare a default hereunder (other than to enforce conversion rights hereunder).
The provisions of this Section 6 are for the purposes of defining the relative rights of the Holder and the Senior Creditors and nothing
in this Note shall impair, as between the Company and the Holder, the obligation of the Company, which is unconditional and absolute,
to pay the Holder the principal thereof and interest thereon, in accordance with the terms of this Note.
