are true and complete as of the date of the applicable Closing, except as otherwise indicated. The Disclosure Schedule shall be

business as presently conducted and as presently proposed to be conducted. The Company is duly qualified and is authorized to do
business and is in good standing as a foreign corporation in all jurisdictions in which the nature of its activities and of its

would not have a material adverse effect on the assets, conditions, affairs or prospects of the Company, financially or otherwise.


 


3.2       Capitalization.


 


(a)       The
authorized capital stock of the Company, immediately prior to the Closing, consists of 7,000,000 shares of Common Stock, par value

affecting enforcement of creditors’ rights and (b) general principles of equity that restrict the availability of equitable
remedies.


 


3.4       Compliance
with Other Instruments. The Company is not in violation or default of any term of its organizational documents, including its
certificate of incorporation, or of any provision of any material mortgage, indenture, contract, agreement, instrument or contract
to which it is party or by which it is bound or of any judgment, decree, order or writ or to its knowledge, of any provision of
any federal or state statute, rule or regulation applicable to the Company. The execution, delivery, and performance of and compliance
with the Transaction Documents, and the issuance and sale of the Shares pursuant hereto, will not, with or without the passage
of time or giving of notice, result in any such violation, or be in conflict with or constitute a default under any such term,
or result in the creation of any mortgage, pledge, lien, encumbrance or charge upon any of the properties or assets of the Company
or the suspension, revocation, impairment, forfeiture or nonrenewal of any permit, license, authorization or approval applicable
to the Company, its business or operations or any of its assets or properties or cause the acceleration of any payments owed to
third parties.

operations or prospects of the Company. No governmental orders, permissions, consents, approvals or authorizations are required
to be obtained and no registrations or declarations are required to be filed in connection with the execution and delivery of the
Transaction Documents or the issuance of the Shares, except such as have been duly and validly obtained or filed, or with respect

3.6       Litigation.
There is no claim, action, suit, proceeding, arbitration, complaint, charge or investigation pending or to the Company’s
knowledge, currently threatened in writing (i) against the Company or any officer, or director of the Company; or (ii) to the Company’s
knowledge, that questions the validity of the Transaction Agreements or the right of the Company to enter into them, or to consummate
the transactions contemplated by the Transaction Agreements; or (iii) to the Company’s knowledge, that would reasonably be
expected to have, either individually or in the aggregate, a material adverse effect. Neither the Company nor, to the Company’s
knowledge, any of its officers, or directors is a party or is named as subject to the provisions of any order, writ, injunction,
judgment or decree of any court or government agency or instrumentality (in the case of officers, or directors, such as would affect
the Company). There is no action, suit, proceeding or investigation by the Company pending or which the Company intends to initiate.
The foregoing includes, without limitation, actions, suits, proceedings or investigations pending or threatened in writing (or
any basis therefor known to the Company) involving the prior employment of any of the Company’s employees, their services
provided in connection with the Company’s business, any information or techniques allegedly proprietary to any of their former
employers or their obligations under any agreements with prior employers.

joint venture, limited liability company, association, or other business entity. The Company is not a participant in any joint
venture, partnership or similar arrangement.


 


3.8       Insurance.
The Company has in full force and effect insurance policies concerning such casualties as would be reasonable and customary for
companies like the Company, with extended coverage, sufficient in amount (subject to reasonable deductions) to allow it to replace
any of its material properties that might be damaged or destroyed.


 


3.9       Permits.
The Company has all franchises, permits, licenses and any similar authority necessary for the conduct of its business, the lack
of which could reasonably be expected to have a Material Adverse Effect. The Company is not in default in any material respect
under any of such franchises, permits, licenses or other similar authority.


 


3.10       FDA
Approvals. The Company possesses all permits, licenses, registrations, certificates, authorizations, orders and approvals from
the appropriate federal, state or foreign regulatory authorities necessary to conduct its business as now conducted, including
all such permits, licenses, registrations, certificates, authorizations, orders and approvals required by the FDA or any other
federal, state or foreign agencies or bodies engaged in the regulation of drugs, pharmaceuticals, medical devices or biohazardous
materials. The Company has not received any notice of proceedings relating to the suspension, modification, revocation or cancellation
of any such permit, license, registration, certificate, authorization, order or approval. Neither the Company nor, to the Company’s
knowledge, any officer, employee or agent of the Company has been convicted of any crime or engaged in any conduct that has previously

or (b), or any similar law, rule or regulation of any other governmental entities, (B) debarment, suspension, or exclusion under

pursuant to its “Fraud, Untrue Statements of Material Facts, Bribery, and Illegal Gratuities” policy as stated at 56
Fed. Reg. 46191 (September 10, 1991) (the “FDA Application Integrity Policy”) and any amendments thereto,
or by any other similar governmental entity pursuant to any similar policy. Neither the Company nor any of its officers, employees,
contractors, and agents has committed any act, made any statement or failed to make any statement that would reasonably be expected
to provide a basis for FDA to invoke the FDA Application Integrity Policy or for any similar governmental entity to invoke a similar
policy. Neither the Company nor any of its officers, employees, or to the Company’s knowledge, any of its contractors or
agents has made any materially false statements on, or material omissions from, any notifications, applications, approvals, reports
and other submissions to FDA or any similar governmental entity.

		4.	Representations
                                         And Warranties
                                         Of Purchaser.



 


Purchaser hereby represents and warrants
to the Company, as follows:


 


4.1       Requisite
Power and Authority. Purchaser has all necessary power and authority to execute and deliver this Agreement and the other Transaction
Documents and to carry out their provisions. All action on Purchaser’s part required for the lawful execution and delivery
of this Agreement and the other Transaction Documents has been taken. Upon their execution and delivery, this Agreement and the
other Transaction Documents will be valid and binding obligations of Purchaser, enforceable in accordance with their terms, except
(a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium or other laws of general application affecting
enforcement of creditors’ rights and (b) as limited by general principles of equity that restrict the availability of equitable
remedies.


 


4.2       Investment
Representations. Purchaser understands that the Shares have not been registered under the Securities Act. Purchaser also understands
that the Shares are being offered and sold pursuant to an exemption from registration contained in the Securities Act based in
part upon Purchaser’s representations contained in the Agreement. Purchaser hereby represents and warrants as follows:


 


(a)       No
Assurances. Purchaser represents that none of the following has been represented, guaranteed or warranted to Purchaser by the
Company and/or its officers, directors, agents, employees or affiliates or any other person, expressly or by implication: (1) the
length of time that Purchaser shall be required to remain as the owner of the Shares; (2) the profit to be realized, if any, as
a result of investment in the Company; or (3) the past performance or experience of the Company’s officers, directors, agents,
employees, affiliates or of any other person, can be interpreted in any way to predict results of the ownership of Shares.


 


(b)       Purchaser
Bears Economic Risk. Purchaser has substantial experience in evaluating and investing in private placement transactions of
securities in companies similar to the Company so that the Purchaser is capable of evaluating the merits and risks of its investment
in the Company and has the capacity to protect its own interests. Purchaser must bear the economic risk of this investment indefinitely
unless the Shares are registered pursuant to the Securities Act, or an exemption from registration is available. Purchaser understands
that the Company has no present intention of registering the Shares or any shares of its Common Stock. Purchaser also understands
that there is no assurance that any exemption from registration under the Securities Act will be available and that, even if available,
such exemption may not allow Purchaser to transfer all or any portion of the Shares under the circumstances, in the amounts or
at the times Purchaser might propose.


 


(c)       Acquisition
for Own Account. Purchaser is acquiring the Shares for Purchaser’s own account for investment only, and not with a view
towards their distribution.


 




    	 	5 	 



     


    




 


(d)       Purchaser
Can Protect Its Interest. Purchaser represents that by reason of its, or of its management’s, business or financial experience,
Purchaser has the capacity to protect its own interests in connection with the transactions contemplated in this Agreement, and
the other Transaction Documents. Purchaser has adequate means of providing for current needs and has no need for liquidity in the
investment in the Company and can afford a complete loss of an investment in the Shares. Purchaser represents that Purchaser’s
financial commitment to all investments (including Purchaser’s investment in the Company and other investments that are not
readily marketable) is reasonable in relationship to Purchaser’s net worth. Purchaser’s investment in the Shares does
not exceed 10% of Purchaser’s net worth. Further, Purchaser is aware of no publication of any advertisement in connection
with the transactions contemplated in the Agreement and Purchaser has not seen or received any general advertisement or general
solicitation with respect to the sale of the Shares.


 


(e)       Risks.
Purchaser recognizes that investment in the Company involves substantial risks, including those referred to below, and has taken
full cognizance of and understands all of the risks related to the purchase of Shares including but not limited to the fact Purchaser
may lose his or her entire investment.


 


(f)       Accredited
Investor. Purchaser represents that it is an accredited investor within the meaning of Regulation D under the Securities Act.


 


(g)       Company
Information. Purchaser has had an opportunity to discuss the Company’s business, management and financial affairs with
directors, officers and management of the Company and has had the opportunity to review the Company’s operations and facilities.
Purchaser has also had the opportunity to ask questions of and receive answers from, the Company and its management regarding the
terms and conditions of this investment. The foregoing, however, does not limit or modify the representations and warranties of
the Company in Section 4 hereof or the right of the Purchaser to rely thereon.


 


(h)       Rule
144. Purchaser acknowledges and agrees that the Shares are “restricted securities” as defined in
Rule 144 promulgated under the Securities Act as in effect from time to time and must be held indefinitely unless they are subsequently
registered under the Securities Act or an exemption from such registration is available. Purchaser has been advised or is aware
of the provisions of Rule 144, which permits limited resale of shares purchased in a private placement subject to the satisfaction
of certain conditions, including, among other things: the availability of certain current public information about the Company,
the resale occurring following the required holding period under Rule 144 and the number of shares being sold during any three-month
period not exceeding specified limitations.


 


(i)       Residence.
If Purchaser is an individual, then Purchaser resides in the state or province identified in the address of Purchaser set forth
on Exhibit A; if Purchaser is a partnership, corporation, limited liability company or other entity, then the office or
offices of Purchaser in which its investment decision was made is located at the address or addresses of Purchaser set forth on
Exhibit A.

Lock-Up Period. The Purchaser
hereby agrees that it will not, without the prior written consent of the managing underwriter, during the period commencing on
the date of the final prospectus relating to the registration by the Company of shares of its Common Stock or any other equity
securities under the Securities Act, on a registration statement on Form S-1 or Form S-3, and ending on the date specified by the
managing underwriter (such period not to exceed one hundred eighty (180) days in the case of the IPO), (i) lend; offer; pledge;
sell; contract to sell; sell any option or contract to purchase; purchase any option or contract to sell; grant any option, right,
or warrant to purchase; or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities
convertible into or exercisable or exchangeable (directly or indirectly) for Common Stock held immediately before the effective
date of the registration statement for such offering or (ii) enter into any swap or other arrangement that transfers to another,
in whole or in part, any of the economic consequences of ownership of such securities, whether any such transaction described in
clause (i) or (ii) above is to be settled by delivery of Common Stock or other securities, in cash, or otherwise.
The Purchaser further agrees to execute such agreements as may be reasonably requested by the underwriters in connection with such
registration that are consistent with this provision or that are necessary to give further effect thereto.


 


(k)       Tax
Consequences. Purchaser confirms that neither the officers of the Company nor any of its affiliates or agents have made any
representation or warranties or statements concerning tax consequences that may arise in connection with his/her investment in
the Company.


 


		5.	Antidilution.



 


Notwithstanding anything
to the contrary herein, the Company and the Purchaser agree that the Shares acquired hereby by the Purchaser are intended to equal
3% of the Fully Diluted Capitalization (defined below), and the Purchaser’s ownership percentage shall remain at 3% of the
Fully Diluted Capitalization through the completion of a Qualified IPO (as defined in the Company’s Amended and Restated
Certificate of Incorporation, on the date hereof). For avoidance of doubt and for purposes of clarification, if Purchaser’s
ownership percentage ever falls below 3% of the Fully Diluted Capitalization after the date hereof (“Antidilution Adjustment
Trigger”), then the Company shall immediately issue to Purchaser additional Shares to the extent that Purchaser’s
ownership equals 3% of the Company’s Fully Diluted Capitalization as of such time. Purchaser shall not be required to make
any payment as a result of the issuance of additional Shares pursuant to the Antidilution Adjustment Trigger. Any additional Shares
subject to the Antidilution Adjustment Trigger shall be reflected on Schedule A, attached hereto, and the Company shall
deliver to the Purchaser a certificate representing the number of additional shares subject to the Antidilution Adjustment Trigger.
“Fully-Diluted Capitalization” means, at any given time, the sum of (a) the number of shares of capital
stock actually outstanding at such time, plus (b) the number of shares of capital stock reserved for issuance at such time under
stock option or other equity incentive plans approved by the Board, including, without limitation the Stock Plan, regardless of
whether the shares of capital stock are actually subject to outstanding options at such time or whether any outstanding options
are actually exercisable at such time, plus (c) the number of shares of capital stock issuable upon conversion, exercise or exchange
of convertible securities actually outstanding at such time.
