NOTE PURCHASE AGREEMENT


 


THIS NOTE PURCHASE
AGREEMENT (the “Purchase Agreement”) is dated as of October 16, 2019, by and among CITTA, Inc.,
a Delaware corporation (the “Company”), and those individuals and/or entities listed in Exhibit A
attached hereto (each a “Lender” and together the “Lenders”).


 


WHEREAS, the Company
desires to raise up to two million dollars (US$2,000,000.00) (the “Loan Amount”) via a convertible note financing
from the Lenders and the Lenders wish to loan the Company the Loan Amount subject to the terms and conditions of this Purchase
Agreement and the convertible promissory note attached hereto as Exhibit B (each a “Note” and together
the “Notes”);


 


NOW, THEREFORE, in
consideration of the premises and the mutual covenants herein contained, and other good and valuable consideration the receipt
and sufficiency of which is hereby acknowledged, the undersigned parties hereby agree as follows:


 


1.            Amount
and Terms of the Notes. The Lenders undertake to lend to the Company the Loan Amount, in the proportions as set forth opposite
each Lender’s name in Exhibit A, against the issuance of the Notes. The Loan Amount shall bear a cumulative annual
interest as specified in the Note and shall have such maturity date set forth therein.


 


2.            Closing.


 


(a)            Initial
Closing. Subject to the terms and conditions of this Purchase Agreement, the initial closing of the sale and purchase of the
Notes hereunder shall take place remotely via the exchange of documents and signatures on such date and time as determined by the
Company (the “Initial Closing”). At the Initial Closing, the Company shall deliver a Note to each Lender participating
therein in the original principal amount set forth opposite each Lender’s name in Exhibit A and each Lender shall
immediately pay its respective portion of the Loan Amount as set forth opposite each Lender’s Name in Exhibit A
by way of check or wire transfer pursuant to the instructions provided by the Company to the Lenders prior to the Initial Closing.


 


(b)            Additional
Closings. Following the Initial Closing, at any time and from time to time during and up to one hundred twenty (120) days following
the Initial Closing (the “Additional Closing Period”), the Company may, at one or more additional closings as
determined by the Company (each an “Additional Closing” and together with the Initial Closing, a “Closing”),
without obtaining the signature, consent or permission of any of the Lenders in the Initial Closing or any prior Additional Closing,
issue additional Notes to other investors (the “New Lenders”) up to the portion of the Loan Amount remaining
after the Initial Closing on the same terms and conditions as set forth herein. The New Lenders may include persons or entities
who are already Lenders under this Purchase Agreement and each New Lender shall execute and deliver a signature page to this
Purchase Agreement and the Note to the Company, becoming a party to, and bound by, this Agreement to the same extent as if the
New Lender had been a Lender at the Initial Closing and each such New Lender shall be deemed to be a Lender for purposes under
this Agreement as of the date of the applicable Additional Closing. The Company, in its sole discretion, may shorten the Additional
Closing Period.


 


3.            Representations
and Warranties of the Company. The Company represents and warrants to the Lenders as follows:


 


(a)            The
Company is duly organized and existing in good standing under the laws of State of Delaware, and has the power to own its properties
and to carry on its business as now conducted.


 


(b)            The
Company has full power, authority and legal right to enter into this Purchase Agreement and each Note and to perform all of its

and the Note constitute the legal, valid, and binding obligation of the Company enforceable in accordance with their respective
terms.


 






    


     


    

 


(c)            All
of the shares of the Company to be issued to the Lender upon the conversion of each Note (if converted) shall be, when
issued, duly authorized, validly issued, fully paid, non-assessable free and clear of all liens, pledges, security interests,
charges and encumbrances and registered in the name of the Lender on the stock ledger of the Company.


 


4.            Representations
and Warranties of the Lender. Each Lender represents and warrants to the Company that:

stage of development so as to be able to evaluate the risks and merits of its investment in the Company and it is able financially
to bear the risks thereof;


 


(b)            The
Lender is entering into this Purchase Agreement and acquiring the Note for the Lender’s own account for the purpose of investment
and not with a view to or for sale in connection with any distribution thereof other than in compliance with the Securities Act
and applicable state securities laws; and


 


5.            Each
Lender understands that (i) each Note has not been registered under the Securities Act by reason of its issuance in a transaction
exempt from the registration requirements of the Securities Act pursuant to Section 4(2) thereof or Rule 504, 505
or 506 promulgated under the Securities Act, (ii) each Note must be held indefinitely unless a subsequent disposition thereof
is registered under the Securities Act or is exempt from such registration, and (iii) each Note will bear a legend substantially

CONVERTIBLE PROMISSORY NOTE


 


	$100,000 (the “Loan Amount”)	 October 16, 2019
	8% Annual Interest	(the “Note Date”)




 


THIS
NOTE is issued pursuant to the terms of that certain Note Purchase Agreement by and among CITTA, Inc. (the “Company”)
and Sidewater Associates I (the “Lender”) and dated October 16, 2019 (the “Purchase
Agreement”). Capitalized terms not elsewhere defined herein shall have the meanings set forth in the Purchase Agreement.


 


FOR
VALUE RECEIVED, the Company hereby promises to pay to the order of the Lender, the principal sum of the Loan Amount, together
with interest thereon. This Note shall bear a simple interest rate of eight percent (8%) per annum based on a 365 day year. The
obligation to pay interest on this Note shall be cumulative.


 


1.            Maturity
Date. If not otherwise converted pursuant to Section 3, the outstanding principal balance and unpaid accrued interest
on this Note shall be due two (2) years from the Note Date (the “Maturity Date”) or prior thereto upon
the Lender’s first written request following an Event of Default of the Company. The Maturity Date may be extended upon mutual
consent of the Company and the Lender.


 


2.            Note
Repayment. All repayments shall be made in lawful money of the United States of America by wire transfer to a bank account
to be designated by the Lender. All Notes outstanding under the Purchase Agreement shall rank equally without preference or priority
of any kind with respect to one another, and all payments with respect to any of the Notes that have not been converted shall be
applied ratably in proportion to the Loan Amounts represented thereby. The Company shall be entitled to repay all or any portion
of the principal or accrued interest outstanding under the Notes upon prior written notice to the Lender.


 


3.            Conversion.


 


3.1            Automatic
Conversion upon Qualified Financing. Notwithstanding the foregoing, at the closing of the Qualified Financing (as hereinafter
defined), the outstanding principal balance and unpaid accrued interest on this Note shall be automatically converted into the
most senior class of shares of the Company issued in such Qualified Financing (the “Shares”) at a price per
share equal to the lower of: (i) 80% of the original price per unit of such Shares or (ii) a maximum company pre-money
valuation of eight million dollars (US$8,000,000) on a fully diluted basis (in each case, the “Conversion Price”).
The exact number of Shares to be issued to Lender upon conversion will be equal to the aggregate outstanding principal and unpaid
accrued interest due on this Note, divided by the Exercise Price. The issuance of such shares upon conversion of this Note shall
be contingent upon execution and delivery by the Lender of the agreements executed and delivered by investors in the Qualified
Financing. The Lender shall thereupon receive all of the rights, preferences and privileges granted to other investors in the Qualified
Financing, including but not limited to any registration and piggyback rights. “Qualified Financing” shall mean
the next transaction or series of related transactions following the date of the Purchase Agreement in which the Company issues
and sells Shares to investors, which may be existing stockholders of the Company, with gross proceeds to the Company of at least
two million dollars (US$2,000,000), excluding the conversion of Notes.


 






    


     


    

 


3.2            Discretionary
Conversion. Unless otherwise automatically converted in a Qualified Financing, at any time prior to the Maturity Date (or any
time after the Maturity Date with the consent of the Company and including prior to a Change of Control that occurs before a Qualified
Financing) the Lender shall be entitled, by written notice to the Company, to convert the outstanding principal balance and unpaid
accrued interest on this Note, in whole or in part, into the most senior class of stock of the Company then outstanding, at a conversion
price based upon a maximum company pre-money valuation of eight million dollars (US$8,000,000) on a fully diluted basis. The shares
issued upon said conversion shall have all preferential and associated rights with said class and given to the investors in the
applicable round of financing, and shall be identical in all terms except for said price. Any election to convert the Note pursuant
to this Section 3.2 will be made in writing and delivered to the Company.


 


3.3            Repayment
Upon Change of Control. In the event the Company consummates a Change of Control (as defined below) prior to the Maturity Date
and prior to the conversion or repayment of this Note, then this Note shall become due and payable upon the date of consummation
of such Change of Control (and following the Company’s receipt of proceeds from a Change of Control) in an amount equal to
the greater of: (i) one and one half times (1.5x) the Loan Amount, plus any accrued and unpaid interest; or (ii) the
net proceeds to be received by Lender if Lender had converted this Note based on a price per share based on a pre-money valuation
of the Company equal to $8,000,000, as calculated on a fully diluted basis, immediately prior to the Change of Control. The Company
will notify Lender in writing of a Change of Control at least five (5) days before the anticipated closing of such Change
of Control. A “Change of Control” means the sale, conveyance, exclusive license outside of the ordinary course
of business, or other disposition of all or substantially all of the Company’s property or business, the Company’s
merger with or into or consolidation with any other corporation, limited liability company or other entity (other than a wholly
owned subsidiary of the Company) or the sale or disposition of a majority of the voting securities of the Company; provided that
the term “Change of Control” shall not include (a) a merger or reorganization of the Company effected exclusively
for the purpose of changing the domicile of the Company or tax-free reorganization, (b) an equity financing in which the Company
is the surviving corporation, or (c) a transaction in which the stockholders of the Company immediately prior to the transaction
own 50% or more of the voting or economic power of the surviving corporation immediately following the transaction in substantially
the same proportions as existed immediately prior to the transaction.


 


4.            Unsecured
Obligation. The Lender hereby acknowledges and agrees that the obligations of the Company hereunder (including, without limitation,
in respect of repayment of the Loan Amount and the accrued but unpaid interest thereon) shall be an unsecured obligation of the
Company in all respects.


 


5.            Governing
Law; Venue. This Note and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall
be governed, construed and interpreted in accordance with the laws of the State of New York without regard to the conflict of law
provisions. The competent courts of the State of New York shall have exclusive jurisdiction to resolve all disputes arising from
or in connection with this Note or the Purchase Agreement.


 


6.            Transfer;
Successors and Assigns. The Lender may not sell, assign, pledge, dispose of or otherwise transfer (collectively, “Transfer”)
this Note, unless the Lender obtains the Company’s prior written approval (such approval to be provided in the Company’s
sole and absolute discretion).


 






    


     


    

 


7.            Notices.
The notice provision of the Purchase Agreement shall apply to this Note.


 


8.            Amendments,
Modifications. Any amendment or modification of this Note shall require the prior written consent of the Company and the Lender.


 


9.            Miscellaneous.
The Company hereby expressly waives presentment, demand for payment, dishonor, notice of dishonor, protest, notice of protest and
any other formality.


 


10.            Stock
Reclassifications; Stock Splits, Combinations and Dividends. If the Shares issuable upon the conversion of this Note
shall be changed into the same or different number of Shares of any class or classes of stock, whether by reclassification,
stock split, stock dividend, or similar event, then and in each such event, the Lender, shall have the right thereafter to
convert all or any portion of this Note into the kind and amount of Shares and property receivable upon such capital
reorganization, reclassification or other change which the Lender would have received had this Note been converted
immediately prior to such capital reorganization, reclassification or other change.


 


11.            Adjustments.
The Company will make an appropriate adjustment to the number of Shares issuable upon conversion and/or the Conversion Price thereof
upon any stock split, combination, dividend, distribution, recapitalization, reorganization, or similar event affecting the Company’s
capital stock other than cash dividends paid or payable from retained earnings (collectively, a "Stock Event"),
so that the Lender will receive, upon conversion, all Shares, dividends, rights and benefits to which the Lender would have been
entitled had Lender converted this Note prior to such Stock Event. The form of this Note need not be changed by reason of any such
adjustment. Any successor entity to the Company will execute and deliver to the Lender a supplement hereto acknowledging such entity's
obligations under this Note. The Company will make adjustments as soon as practicable following any Stock Event, and immediately
thereafter give notice to the Lender of all facts and calculations associated with such adjustment. Stock Event adjustments may
be waived by the Lender, in its sole and absolute discretion.


 


12.            Default.
If there shall be any Event of Default (as defined below) hereunder, at the option and upon the declaration of the Lender of this
Note and upon written notice to the Company (which election and notice shall not be required in the case of an Event of Default
under Section 12(b) or 12(c)), this Note shall accelerate and all Loan Amount and unpaid accrued interest shall become
due, payable and collectible. The occurrence of any one or more of the following shall constitute an “Event of Default”
hereunder:


 


(a)            The
Company fails to pay timely any of the Loan Amount due under this Note on the date the same becomes due and payable or any accrued
interest or other amounts due under this Note on the date the same becomes due and payable or within five (5) business days
thereafter;


 


(b)            The
Company files any petition or action for relief under any bankruptcy, reorganization, insolvency or moratorium law or any other
law for the relief of, or relating to, debtors, now or hereafter in effect, or makes any assignment for the benefit of creditors
or takes any corporate action in furtherance of any of the foregoing; or


 


(c)            An
involuntary petition is filed against the Company (unless such petition is dismissed or discharged within sixty (60) days) under
any bankruptcy statute now or hereafter in effect, or a custodian, receiver, trustee, assignee for the benefit of creditors (or
other similar official) is appointed to take possession, custody or control of any property of the Company and is not removed within
sixty (60) days from the date of such appointment.


 






    


     


    

 


		14.	Default Remedies.



 


(a)            If
an Event of Default (other than an insolvency Event of Default) has occurred and is continuing, the Lender, by notice to the Company,
may declare the Loan Amount of this Note and all accrued interest thereon to be immediately due and payable, and upon any such
declaration, such Loan Amount and accrued interest shall thereupon become due and payable immediately within five (5) business
days from the Lender’s written request. In the event the Company fails to pay all outstanding Amounts within this five (5) business
day period, the interest rate on the unpaid and outstanding Loan Amount of this Note shall be increased to, and this Note shall
bear interest at, a monthly rate equal to one and a half percent (1.5%) or to the maximum rate permitted by law (the "Default
Rate") from the expiration of the five (5) business day period until such unpaid and outstanding Loan Amount of this
Note is repaid in full. If an insolvency Event of Default has occurred, the Loan Amount of this Note and accrued Interest thereon
will become immediately due and payable without any declaration or any act on the part of any Lender. Such declaration of acceleration
may be rescinded and past defaults may be waived by the Lender.


 


(b)            No
course of dealing or delay or failure on the part of the Lender to exercise any right under this Section shall operate as
a waiver of such right or otherwise prejudice the Lender’s rights, powers and remedies. The Company will pay or reimburse
the Lender, to the extent permitted by law, for all reasonable costs and expenses, including but not limited to reasonable attorneys’
fees, incurred by the Lender in collecting any sums due on this Note or in otherwise enforcing any of the Lender's rights hereunder.


 


(c)            No
right or remedy herein conferred upon the Lender is intended to be exclusive of any other right or remedy contained herein or existing
at law, in equity, by statute or otherwise, and every such right or remedy shall be cumulative and shall be in addition to every
other such right or remedy contained herein and therein or now or hereafter existing at law, in equity, by statute or otherwise.


 


15.            Indemnity.
The Company agrees to indemnify and hold the Lender harmless from and against any and all suits, actions, proceedings, claims,
damages, losses, liabilities and expenses of any kind and nature whatsoever (including attorneys' fees and disbursements and other
costs of investigation or defense) that may be instituted or asserted against or incurred by the Lender as the result of credit
having been extended, suspended or terminated under this Note or with respect to the execution, delivery, enforcement, performance
and administration of, or in any other way arising out of or relating to, this Note or the transactions referred to herein and
any actions or omissions with respect to any of the foregoing, except to the extent that the Lender is finally determined by a
court of competent jurisdiction to have resulted solely from the gross negligence or willful misconduct of the Lender.


 


16.            Replacement
of Note. If the Lender of record loses this Note, the Company shall issue an identical replacement Note to the Lender upon
the Lender’s delivery to the Company of an executed lost note affidavit stating the facts surrounding such loss of this Note
and an executed indemnity agreement indemnifying and holding harmless the Company against any losses incurred or liabilities suffered
by the Company or claims against the Company by any other holders or transferees of this Note related to or from the issuance of
the replacement Note by the Company, which lost note affidavit and indemnity agreement shall be in a form reasonably satisfactory
to the Company.


 


17.            Reinstatement.
This Note shall continue to be effective, or be reinstated, as applicable, if at any time payment of all or any part hereof is
rescinded or must otherwise be returned or restored by the Lender upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of the Company, as though such payments had not been made.


 






    


     


    

 


18.            Additional
Covenants. Until this Note is paid in full, the Company shall not without the prior written consent of the Lender (such consent
which shall not be unreasonably delayed, withheld, or conditioned): (i) issue any securities other than strictly pursuant
to a Qualified Financing or pursuant to a duly adopted Stock Incentive Plan; (ii) incur or agree to incur any indebtedness
that is senior to this Note (except for the SQN Note as hereinafter defined) ; (iii) make any loans to, or assume or guarantee
any debt or other obligations of another person or entity in excess of $10,000; (iv) enter into or modify any affiliated party
transaction or pay current officers and directors in excess of that which has previously been disclosed in writing to the Lender;
(v) place any liens or encumbrances on, or cause any liens or encumbrances to be placed on, or transfer, convey, assign, pledge
or grant any security interests in, the capital stock or assets or properties of the Company other than those liens that may be
granted to SQN under the SQN Note; or (vi) declare or pay any dividends or distributions on its capital stock until this Note
is paid in full.


 


19.            Financial
Statements. So long as this Note is outstanding, the Company shall furnish to the Lender:


 


(a)            Monthly
Reports. Within thirty (30) days following the end of each fiscal month of the Company, a copy of the consolidated and consolidating
balance sheet, income statement and statement of cash flow (the "Financial Statements") of the Company and its
subsidiaries, internally prepared for such fiscal month in accordance with generally accepted accounting principles in the United
States, consistently applied, setting forth in comparative form the corresponding figures for that date and period, accompanied
by a certificate executed by the Chief Executive Officer or Chief Financial Offer of the Company certifying that (i) such
Financial Statements are complete, true and correct and (ii) to his or her actual knowledge, the Company is not in default
of any of its covenants made hereunder.


 


(b)            Annual
Reports. Within ninety (90) days following the close of each fiscal year of the Company, the Financial Statements for
such fiscal year certified by an officer of the Company without qualification in reasonable detail, setting forth in
comparative form the corresponding figures for the corresponding date and period in the preceding fiscal year, and
accompanied by other detailed reports from such accountants to the Company (including, without limitation, any management
letters) in connection with each annual or interim audit or review of the books of the Company by such accountants. In the
event the Board of Directors of the Company approves the annual Financial Statements to be audited, the Lender shall be
provided with Financial Statements audited by an independent certified public accounting firm reasonably acceptable to the
Lender.


 


20.            Seniority.
The Lender hereby confirms and acknowledges that this Note shall rank pari passu in seniority with any other Note issued under
the Purchase Agreement. The Lender further confirms and acknowledges that this Note shall rank junior in all respects (including
in respect of payment) to that certain promissory note that may be issued by the Company to SQN Venture Income Fund, L.P., or an
