STOCK OPTION PLAN

 

1.) Purposes.

 

The principal purposes of
the NORTHERN RESEARCH LABORATORIES, INC. (the “Corporation”) 1998 Stock Option Plan (the “Plan”) are: (a) to improve
individual performance by providing long-term incentives and rewards to certain employees, directors and/or consultants of the Corporation;
(b) to assist the Corporation in attracting, retaining and motivating certain employees, directors and/or consultants with experience
and ability; and (c) to align the interests of such persons with those of the Corporation’s shareholders.

 

Options granted under this
Plan may either be Incentive Stock Options qualified under Section 422 of the Code or Non-Qualified Stock Options.

 

2.)

For purposes of this Plan, the following terms shall have
the meanings indicated below:

 

(a)
“Capital Stock” - any of the Corporation’s authorized but unissued shares of voting common stock, One Cent ($0.01) par
value.

(c)
“Committee” - a committee consisting solely of not less than two members of the Board of Directors of the Corporation who
are “Non-Employee Directors” within the meaning of and to the extent required by the general rules and regulations promulgated

“Exchange Act” - the Securities Exchange Act of 1934, as amended.

 

(f)

more national securities exchanges or is quoted on the NASDAQ National Market System, the reported last sales price on such
principal exchange or system on the date in question (if such security shall not have been traded on such principal exchange on such
date, the reported last sales price on such principal exchange on the first day prior thereto on which such security was so traded);
or (b) if the security is not listed for trading on a national securities exchange and is not quoted on the NASDAQ National Market
System but is quoted on the NASDAQ Small Cap System or is otherwise traded in the over-the-counter market, the mean of the highest
and lowest bid prices for such security on the date in question (if there are no such bid prices for such security on such date, the
mean of the highest and lowest bid prices on the first day prior thereto on which such prices existed); or (c) if neither (a) nor
(b) is applicable, by any means deemed fair and reasonable by the Committee (as defined above), which determination shall be final
and binding on all parties.

 

     

     

    

 

(g)
“Incentive Stock Option” - an option defined in Section 422 of the Code to purchase shares of the Capital Stock of the Corporation.
Incentive Stock Options granted hereunder are intended to qualify as “incentive stock options” under the Code. If any provision
of this Plan is susceptible to more than one interpretation, such interpretation shall be given thereto as is consistent with the Incentive
Stock Options granted under this Plan being treated as incentive stock options under the Code.

 

(h)
“Non-Qualified Stock Option” - an option to purchase Capital Stock of the Corporation not intended to qualify as an Incentive
Stock Option as defined in Section 422 of the Code.

 

(i)

the Corporation.

to this Plan, or any other class of stock of the Corporation which may be substituted therefor by exchange, stock split or otherwise.

the option, each of the corporations other than the last corporation in the chain owns stock possessing more than fifty percent (50%)
of the total combined voting power of all classes of stock in one of the other corporations in such chain. The term shall include any
subsidiaries which become such after adoption of this Plan.

 

(p) A
“Parent” - a corporation that directly, or indirectly through related corporations, owns more than fifty percent (50%) of
the voting power of the shares entitled to vote for directors of the Corporation. The term shall include a corporation which becomes such
after adoption of this Plan.

 

(q) “Securities
Act” - the Securities Act of 1933, as amended.

 

    2

     

    

 

3.)
Option Stock Available Under Plan.

 

The Corporation’s
authorized Capital Stock in an amount equal to Three Million (3,000,000) shares is hereby made available, and shall be reserved for issuance
under this Plan. The aggregate number of shares available under this Plan shall be subject to adjustment on the occurrence of any of the
events and in the manner set forth in Section 8. Except as provided in Section 8, in no event shall the number of shares reserved be reduced
below the number of shares issuable upon exercise of outstanding Options. If an Option shall expire or terminate for any reason without
having been exercised in full, the unpurchased shares, shall (unless the Plan shall have been terminated) become available for other Options
under the Plan.

 

4.)
Administration.

 

The Plan shall
be administered by the Committee. The Corporation shall grant Options pursuant to the Plan upon determinations of the Committee as to
which of the eligible persons shall be granted Options, the number of shares to be optioned and the term during which any such Options
may be exercised. The Committee may from time to time adopt rules and regulations for carrying out the Plan and shall have authority and
discretion to interpret and construe any provision of the Plan. Each determination, interpretation or other action made or taken by the
Committee pursuant to the provisions of the Plan shall be final and conclusive. No member of the Committee will be liable for any action
or determination made in good faith with respect to the Plan or any Option granted under the Plan.

 

5.)
Eligibility for Incentive Stock Options.

 

Incentive Stock Options may
only be granted to an officer, management level employee or other employee of the Corporation or any of its Subsidiaries. A director of
the Corporation who is not also an employee shall not be eligible to receive an Incentive Stock Option. In selecting the employees to
whom Incentive Stock Options shall be granted, as well as determining the number of shares subject to each Option, the Committee shall
take into consideration such factors as it deems relevant in connection with accomplishing the purposes of the Plan.

 

(a)
For any calendar year, the aggregate Fair Market Value (determined at the Option Date) of the stock with respect to which any Incentive
Stock Options are exercisable for the first time by any individual employee (under all Incentive Stock Option plans of the Corporation,
the Parent, and all Subsidiary corporations) shall not exceed $100,000 (or such other amount as may be prescribed by the Code from time
to time).

 

(b)
Subject to the provisions of Section 3, an employee who has been granted an Option may, if he or she is otherwise eligible, be granted
an additional Option or Options if the Committee shall so determine.

 

(c)
No Incentive Stock Option may be granted under this Plan later than the expiration of ten (10) years from the effective date of the Plan.

 

(d) To the extent that the
aggregate Fair Market Value (determined as of the date an Incentive Stock Option is granted) of the shares of Option Stock with
respect to which the Incentive Stock Options are exercisable for the first time by a recipient during any calendar year (under the
Plan and any other incentive stock option plans of the Corporation or any Subsidiary or Parent) exceeds $100,000 (or such other
amount as may be prescribed by the Code from time to time), such excess Options will be treated as Non-Qualified Stock Options. The
determination will be made by taking Incentive Stock Options into account in the order in which they were granted. If such excess
only applies to a portion of an Incentive Stock Option, the Committee, in its discretion, will designate which shares will be
treated as shares to be acquired upon exercise of an Incentive Stock Option.

 

    3

     

    

 

6.)
Eligibility for Non-Qualified Stock Options.

 

Non-Qualified
Stock Options may be granted only to an officer, director, management level employee, other employee or consultant of the Corporation
or a Subsidiary. No further restrictions are placed on the Committee in determining eligibility for granting Non-Qualified Stock Options.

 

7.)
Terms and Conditions of Options.

 

Whenever the Committee
shall designate an Optionee, it shall communicate to the Secretary of the Corporation the name of the Optionee, the number of shares to
be optioned and such other terms and conditions as it shall determine, not inconsistent with the provisions of this Plan. The President
or other officer of the Corporation shall then enter into an Option Agreement with the Optionee, complying with and subject to the following
terms and conditions and setting forth such other terms and conditions of the Option as determined by the Committee:

 

(a)
Number of Shares and Option Price.

 

The Option Agreement shall state the
total number of shares to which it pertains. The price of Option Stock for an Incentive Stock Option, shall be not less than one hundred
percent (100%) of the Fair Market Value of the Option Stock at the Option Date. The price of the Option Stock for a Non-Qualified Stock
Option shall be determined by the Committee and may be less than the Fair Market Value at the Option Date. In the event an Incentive Stock
Option is granted to an employee, who, at the Option Date, owns more than ten percent (10%) of the total combined voting power of all
classes of the Corporation’s stock then outstanding, the price of the shares of common stock which will be covered by such Option
shall be at least one hundred ten percent (110%) of the Fair Market Value of the common stock at the Option Date. The Option price shall
be subject to adjustment as provided in Section 8 hereof

 

(b)
Time and Manner of Exercise of Option.

 

The vesting and time of exercise of
each Option shall be determined from time to time by the Committee and shall be set forth in the Option Agreement with each Optionee.
Notwithstanding the foregoing, no option may be exercised after ten (10) years from the date on which the option was granted; provided
that no incentive stock option granted to a 10% Holder may be exercised after five (5) years from the date on which it was granted.

 

(c)
Termination of Employment, Except Death or Disability.

 

In the event that an employee or director
Optionee shall cease to be employed by the Corporation for any reason other than his or her death, disability or “for cause,”
such Optionee shall have the right to exercise any vested outstanding Options which were exercisable at the time of termination of employment
at any time within three (3) months after the termination of the employee or until the earlier date of termination thereof under this
Plan or the Option Agreement, unless otherwise set forth in the Option Agreement. Any vested Options not exercised within the three (3)
month period shall terminate at the expiration of such period, unless otherwise set forth in the Option Agreement. In the event that a
consultant Optionee shall cease to be engaged by the Corporation for any reason, all Options held by such Optionee shall immediately terminate,
unless otherwise set forth in the Option Agreement. In the event that an employee Optionee shall be terminated “for cause”
including but not limited to: (i) willful breach of any agreement entered into with the Corporation; (ii) misappropriation of the Corporation’s
property, fraud, embezzlement, breach of fiduciary duty, other acts of dishonesty against the Corporation; or (iii) conviction of any
felony or crime involving moral turpitude, the Option shall terminate as of the date of the Optionee’s termination of employment.

 

    4

     

    

 

(d)
Death or Disability of Optionee.

 

If an employee Optionee shall die or
become disabled within the definition of Section 22(e)(3) of the Code: (i) while in the employ of the Corporation or any Subsidiary or
(ii) while any Options remain exercisable pursuant to paragraph (c) of this section after the termination of his or her employment with
the Corporation or any Subsidiary as provided in paragraph (c) of this section (other than “for cause”), and in either case
shall not have fully exercised his or her vested Options, any vested Options granted pursuant to the Plan which were exercisable at the
date of termination of employment shall be exercisable only within six (6) months following his or her death or date of disability or
until the earlier originally stated expiration thereof, unless otherwise set forth in the Option Agreement. In the case of death, such
Option shall be exercised pursuant to subparagraph (e) of this Section by the person or persons to whom the Optionee’s rights under
the Option shall pass by the Optionee’s will or by the laws of descent and distribution, and only to the extent that such Options
were exercisable at the time of death.

 

(e) Transfer
of Option. Each Incentive Stock Option granted hereunder shall not be transferable by the Optionee other than by will or by the
laws of descent and distribution, and shall be, during the Optionee’s lifetime, exercisable only by the Optionee or
Optionee’s guardian or legal representative. Each Non-Qualified Stock Option granted hereunder may be transferred by the
Optionee to a member of the Optionee’s immediate family, to a trust established for the benefit of the Optionee or a member of
the Optionee’s immediate family, or to a charitable non-profit organization. Except as permitted by the preceding sentences,
each Option granted under the Plan and the rights and privilege thereby conferred shall not be transferred, assigned or pledged in
any way (whether by operation of law or otherwise), and shall not be subject to execution, attachment or similar process. Upon any
attempt to so transfer, assign, pledge or otherwise dispose of the Option, or of any right or privilege conferred thereby, contrary
to the provisions of the Option or the Plan, or upon levy of any attachment or similar process upon such rights and privileges, the
Option, and such rights and privileges, shall immediately become null and void. A transfer of Non-Qualified Stock Options under the
terms of the Plan may result in the termination of the Company’s eligibility to register option stock under the Securities Act
and Optionees should make inquiry as to eligibility for registration prior to exercising any Option.

 

(f)
Manner of Exercise of Options.

 

An Option may be exercised, in whole
or in part, at such time or times and with such rights with respect to such shares which have accrued and are in effect. Such Option shall
be exercisable only by: (i) written notice to the Corporation of intent to exercise the Option with respect to a specified number of shares
of stock; (ii) tendering the original Option Agreement to the Corporation; and (iii) payment to the Corporation of the amount of the Option
purchase price for the number of shares of stock with respect to which the Option is then exercised. Payment of the Option purchase price
may be made in cash (including certified check, bank draft or postal or express money order), or by any other method of payment which
the Committee shall approve and, in the case of an Incentive Stock Option, which shall not be inconsistent with the provisions of Section
422 of the Code; provided, however, that there shall be no such exercise at any one time as to fewer than 100 shares (or such lesser number
of shares as the Committee may from time to time determine in its discretion) or all of the remaining shares then purchasable by the Optionee
or person exercising the Option. When shares of stock are issued to the Optionee pursuant to the exercise of an Option, the fact of such
issuance shall be noted on the Option Agreement by the Corporation before the Option Agreement is returned to the Optionee. When all shares
of Optioned stock covered by the Option Agreement have been issued to the Optionee, or the Option shall expire, the Option Agreement shall
be canceled and retained by the Corporation.

 

    5

     

    

 

(g)
Option Certificate.

 

The Board of Directors shall have discretion
to issue a certificate representing an Option granted pursuant to this Plan. Such certificate shall be surrendered to the Corporation
upon exercise of the Option.

 

(h)
Delivery of Certificate.

 

Except where shares are held for unpaid withholding
taxes, between fifteen (15) and thirty (30) days after receipt of the written notice and payment specified above, the Corporation shall
deliver to the Optionee certificates for the number of shares with respect to which the Option has been exercised, issued in the Optionee’s
name; provided, however, that such delivery shall be deemed effected for all purposes when the Corporation, or the stock transfer agent
for the Corporation, shall have deposited such certificates in the United States mail, postage prepaid, addressed to the Optionee and
the address specified in the written notice of exercise.

 

(i) Other Provisions.

 

The Option Agreements under this Section
shall contain such other provisions as the Committee shall deem advisable.

 

8.)
Adjustments.

 

In the event that the outstanding
shares of the common stock of the Corporation are changed into or exchanged for a different number or kind of shares or other securities
of the Company or of another corporation by reason of any reorganization, merger, consolidation, recapitalization, reclassification, stock
split-up, combination of shares or dividends payable in capital stock, appropriate adjustment shall be made in the number and kind of
shares as to which Options may be granted under the Plan and as to which outstanding Options or portions thereof then unexercised shall
be exercisable, to the end that the proportionate interest of the participant shall be maintained as before the occurrence of such event;
such adjustment in outstanding Options shall be made without change in the total price applicable to the unexercised portion of such Options
and with a corresponding adjustment in the Option Price per share. No such adjustment shall be made which shall, within the meaning of
any applicable sections of the Code, constitute a modification, extension or renewal of an Option or a grant of additional benefits to
a participant.

 

If the Corporation is a party
to a merger, consolidation, reorganization or similar corporate transaction and if, as a result of that transaction, its shares of common
stock are exchanged for: (i) other securities of the Corporation or (ii) securities of another corporation which has assumed the outstanding
options under the Plan or has substituted for such Options its own Options, then each Optionee shall be entitled (subject to the conditions
stated herein or in such substituted Options, if any), in respect of that Optionee’s Options, to purchase that amount of such other
securities of the Corporation or of such other corporation as is sufficient to ensure that the value of the Optionee’s Options immediately
before the corporate transaction is equivalent to the value of such Options immediately after the transaction, taking into account the
Option Price of the Option before such transaction, the fair market value per share of the common stock immediately before such transaction
and the fair market value immediately after the transaction, of the securities then subject to that Option (or to the option substituted
for that Option, if any). Upon the happening of any such corporate transaction, the class and aggregate number of shares subject to the
Plan which have been heretofore or may be hereafter granted under the Plan shall be appropriately adjusted to reflect the events specified
in this clause.

 

    6

     

    

 

9.)
Change in Control.

 

(a) Change in
Control.

 

For
purposes of this Section 9(a), a “Change in Control” of the Corporation will mean (i) the sale, lease, exchange or other
transfer of substantially all of the assets of the Corporation (in one transaction or in a series of related transactions) to a person
or entity that is not controlled, directly or indirectly, by the Corporation, (ii) a merger or consolidation to which the Corporation
is a party if the stockholders of the Corporation immediately prior to effective date of such merger or consolidation do not have “beneficial
ownership” (as defined in Rule 13d-3 under the Exchange Act) immediately following the effective date of such merger or consolidation
of more than 80% of the combined voting power of the surviving corporation’s outstanding securities ordinarily having the right
to vote at elections of directors, or (iii) a change in control of the Corporation of a nature that would be required to be reported
pursuant to Section 13 or 15(d) of the Exchange Act, whether or not the Corporation is then subject to such reporting requirements, including,
without limitation, such time as (1) any person becomes, after the effective date of the Plan, the “beneficial owner” (as
defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of 40% or more of the combined voting power of the Corporation’s
outstanding securities ordinarily having the right to vote at elections of directors, or (2) individuals who constitute the Board of
Directors on the effective date of the Plan cease for any reason to constitute at least a majority of the Board, provided that any person
becoming a director subsequent to the effective date of the Plan whose election, or nomination for election by the Corporation’s
stockholders, was approved by a vote of at least a majority of the directors comprising the Board on the effective date of the Plan will,
for purposes of this clause (2), be considered as though such persons were a member of the Board of Directors on the effective date of
the Plan.

 

(b)
Acceleration of Vesting.

 

Without limiting the authority of the Committee
under Section 4 of the Plan, if a Change in Control of the Corporation occurs, then, if approved by the Committee in its sole discretion
either in an agreement evidencing an Option grant at the time of grant or at any time after the grant of an Option, all Options will become
immediately exercisable in full and will remain exercisable in accordance with the terms of the Plan; provided, however, that a recipient
of Incentive Stock Options may elect that such acceleration of vesting not apply with respect to some or all of the Incentive Stock Options
granted to him by so notifying the Committee in writing within three (3) business days of being notified of the Committee’s actions
pursuant to this Section 9(b).

 

(c)
Cash Payment for Options.

 

If a Change in Control of the Corporation occurs,
then the Committee in its sole discretion either in an agreement evidencing an Option grant at the time of grant or at any time after
the grant of an Option, and without the consent of any Option recipient effected thereby, may determine that some or all recipients holding
outstanding Options will receive, with respect to and in lieu of some or all of the shares of Option Stock, as of the effective date of
any such Change in Control of the Corporation, cash in an amount equal to the excess of the Fair Market Value of such shares either immediately
prior to the effective date of such Change in Control of the Corporation or, if greater, determined on the basis of the amount paid as
consideration by the other party(ies) to the Change in Control transaction over the exercise price per share of such Options.

 

    7

     

    

 

(d) Limitation
on Change in Control Payments.

 

Notwithstanding anything in Section
9(b) or 9(c) of the Plan to the contrary, if the Corporation is then subject to the provisions of Section 280G of the Code, and if the
acceleration of the vesting of an Option as provided in Section 9(b) or the payment of cash in exchange for all or part of an Option as
provided in Section 9(c) (which acceleration or payment could be deemed a “payment” within the meaning of Section 28OG(b)(2)
of the Code), together with any other payments which such recipient has the right to receive from the Corporation or any corporation that
is a member of an “affiliated group” (as defined in Section 1504(a) of the Code without regard to Section 1504(b) of the Code)
of which the Corporation is a member, would constitute a “parachute payment” (as defined in Section 28OG(b)(2) of the Code),
then the payments to such recipient pursuant to Section 9(b) or 9(c) will be reduced to the largest amount as will result in no portion
of such payments being subject to the excise tax imposed by Section 4999 of the Code; provided, however, that if such recipient is subject
to a separate agreement with the Corporation or a Subsidiary which specifically provides that payments attributable to one or more forms
of employee stock incentives or to payments made in lieu of employee stock incentives will not reduce any other payments under such agreement,
even if it would constitute an excess parachute payment, then the limitations of this Section 9(d) will, to that extent, not apply.

 

10.)
Rights as Stockholder.

 

An Optionee shall not, by
reason of any Option granted hereunder, have any right of a stockholder of the Corporation with respect to the shares covered by his or
her Option until such shares shall have been issued to the Optionee.

 

11.)
No Obligation to Exercise Option; Maintenance of Relationship.

 

The granting of an Option
shall impose no obligation upon the Optionee to exercise such Option. Nothing in the Plan or in any Option Agreement entered into pursuant
hereto shall be construed to confer upon any Option holder any right to continue as an employee, consultant or member of the Corporation’s
Board of Directors or interfere in any way with the right of the Corporation to terminate his or her relationship with the Corporation
at any time.

 

12.)
Withholding Taxes.

 

Whenever
under the Plan shares of Option Stock are to be issued upon exercise of the Options granted hereunder and prior to the delivery of
any certificate or certificates for said shares by the Corporation, the Corporation shall have the right to require the Optionee to
remit to the Corporation an amount sufficient to satisfy any federal and state withholding or other employment taxes resulting from
such exercise. In the event that withholding taxes are not paid within five days after the date of exercise, to the extent permitted
by law the Corporation shall have the right, but not the obligation, to cause such withholding taxes to be satisfied by reducing the
number of shares of stock deliverable or by offsetting such withholding taxes against amounts otherwise due from the Corporation to
the Optionee. If withholding taxes are paid by reduction of the number of shares deliverable to Optionee, such shares shall be
valued at the Fair Market Value as of the fifth business day following the date of exercise.

 

13.)
Purchase for Investment; Rights of Holder on Subsequent Registration.

 

Unless the shares to be issued
upon exercise of an Option granted under the Plan have been effectively registered under the Securities Act, the Corporation shall be
under no obligation to issue any shares covered by any Option unless the person who exercises such Option, whether such exercise is in
whole or in part, shall give a written representation and undertaking to the Corporation which is satisfactory in form and scope to counsel
for the Corporation and upon which, in the opinion of such counsel, the Corporation may reasonably rely, that he or she is acquiring the
shares issued to him or her pursuant to such exercise of the Option for his or her own account as an investment and not with a view to,
or for sale in connection with, the distribution of any such shares, and that he or she will make no transfer of the same except in compliance
with any rules and regulations in force at the time of such transfer under the Securities Act, or any other applicable law, and that if
shares are issued without such registration a legend to this effect may be endorsed on the securities so issued and a “stop transfer”
restriction may be placed in the stock transfer records of the Corporation. In the event that the Company shall, nevertheless, deem it
necessary or desirable to register under the Securities Act or other applicable statutes any shares with respect to which an Option shall
have been exercised, or to qualify any such shares for exemption from the Securities Act or other applicable statutes, then the Corporation
shall take such action at its own expense and may require from each participant such information in writing for use in any registration
statement, prospectus, preliminary prospectus or offering circular as is reasonably necessary for such purpose and may require reasonable
indemnity to the Company and its officers and directors from such holder against all losses, claims, damages and liabilities arising from
such use of the information so furnished and caused by any untrue statement of any material fact required to be stated therein or necessary
to make the statement therein not misleading in light of the circumstances under which they were made.

 

    8

     

    

 

14.)
Market Standoff.

 

To the extent requested by
the Corporation and any underwriter of securities of the Corporation in connection with a firm commitment underwriting, no holder of any
shares of Option Stock will sell or otherwise transfer any such shares not included in such underwriting, or not previously registered
pursuant to a registration statement filed under the Securities Act, during the one hundred and twenty (120) day period following the
effective date of the registration statement filed with the Securities and Exchange Commission in connection with such offering.

 

15.)
Modification of Outstanding Options.

 

The Committee may accelerate
the exercisability of an outstanding Option and may authorize modification of any outstanding Option with the consent of the Optionee
when and subject to such conditions as are -deemed to be in the best interests of the Corporation and in accordance with the purposes
of the Plan.

 

16.)
Foreign Employees.

 

Without amending the Plan,
the Committee may grant Options to eligible employees who are foreign nationals on such terms and conditions different from those specified
in this Plan as may in the judgment of the Committee be necessary or desirable to foster and promote achievement of the purposes of the
Plan, and, in furtherance of such purposes the Committee may make such modification, amendments, procedures, subplans and the like as
may be necessary or advisable to comply with provisions of laws in other countries in which the Corporation operates or has employees.

 

17.)
Approval of Shareholders.

 

This Plan is expressly subject
to approval of the Corporation’s shareholders, and if it is not so approved on or before twelve (12) months after the date of adoption
of this Plan by the Board of Directors, the Plan shall not come into effect and any Options granted pursuant to this Plan shall be deemed
canceled.

3.1 Information About the
Company. The Lender has obtained all information about the Company as the Lender believes relevant to the decision to purchase the
Note and the Warrant including, but not limited to, the Company’s Articles of Incorporation and the Company’s
Bylaws. The Lender has also had the opportunity to ask questions of, and to receive answers from the Company or an agent or a representative
of the Company concerning the terms and conditions of the investment and the business and affairs of the Company and to obtain any additional
information necessary to verify such information, and the Lender has received such information concerning the Company as the Lender considers
necessary or advisable in order to form a decision concerning an investment in the Company.

 

The Lender understands that any document which the Lender may have
been shown or of which the Lender may have been furnished a copy, is not a prospectus, placement memorandum, offering circular, offering
statement, or similar document. Any such document was not prepared, and the Lender understands that any such document was not prepared,
with the purpose of providing full and accurate disclosure to investors. The Lender understands that any such document has been furnished
to the Lender only as part of an overall furnishing of information about the Company and that the Lender has viewed the information set
forth therein with a critical frame of mind and, to the extent that information contained in any such document was deemed by the Lender
to be important information in making an investment decision, the Lender has discussed such information with officers and other personnel
of the Company in order to form a better judgment regarding the accuracy and adequacy of such information. The Lender agrees that no statement
in any document, even if framed as a factual statement, will, of itself, constitute a factual representation by the Company in light of
the various purposes for which any such document may have been created.

The Lender acknowledges and understands that any information provided about the Company’s future plans and prospects is uncertain

or State Regulators. The Lender understands that this transaction has not been reviewed or approved by the United States Securities
and Exchange Commission (the “Commission”) or by any state securities or other authority and, because of the small number

been made available to the Lender and the Lender’s representatives, such as attorneys, accountants and/or purchaser representatives.

 

3.4 High Degree of Risk.
The Lender realizes that this investment involves a high degree of risk, including the risk of loss of all investment in the Company.

Risk. The Lender is able to bear the economic risk of the investment, including the total loss of such investment.

The Lender believes, in light of the information provided pursuant to paragraph 3.1 above, that investing funds pursuant to the terms
of this Agreement is an appropriate and suitable investment for the Lender.

 

3.7 Financial Condition.
The Lender’s current financial condition is such that (and the Lender expects its financial condition to be such that in the near
future) the Lender does not have any present or contemplated need to dispose of any portion of the Note, Warrant or Warrant Shares to
satisfy any existing or contemplated undertaking, need or indebtedness.

 

3.8 Business Sophistication.
The Lender is experienced and knowledgeable in financial and business matters to the extent that the Lender is capable of evaluating the
merits and risks of the prospective investment in the Securities. The Lender has obtained, to the extent the Lender deems necessary, personal
and professional advice with respect to the risks inherent in the investment in the Securities in light of the Lender’s financial
condition and investment needs. The Lender has been given access to full and complete information regarding the Company and has utilized
such access to its satisfaction for the purpose of obtaining information and, particularly, the Lender has obtained and has had the opportunity
to obtain, information from the Company as set forth in Section 3.1 above.

SECTION 4 - COVENANTS OF THE BORROWER

 

4.1 The Lender and the Company
acknowledge that the Securities have not been registered under the Securities Act of 1933, as amended (the “Securities Act”)
or applicable state securities laws and that the Securities will be issued to the Lender in reliance on exemptions from the registration
requirements of the Securities Act and applicable state securities laws and in reliance on the Lender’s and the Company’s
representations and agreements contained herein. The Lender is acquiring the Securities for the account of the Lender for investment purposes
only and not with a view to their resale or distribution. The Lender has no present intention to divide its participation with others
or to resell or otherwise dispose of all or any part of the Securities.

 

4.2 The Lender agrees that
if the Securities or any part thereof are sold or distributed in the future, the Lender shall sell or distribute them pursuant to the
requirements of the Securities Act and applicable state securities laws. The Lender agrees that the Lender will not transfer any part
of the Securities without (i) obtaining a “no action” letter from the Commission and applicable state securities commissions;
(ii) obtaining an opinion of counsel satisfactory in form and substance to the Company to the effect that such transfer is exempt from
the registration requirements under the Securities Act and applicable state securities laws; or (iii) registration.

 

    5

     

    

 

4.3 The Lender understands
that the Company at a future date may file a registration or offering statement (the “Registration Statement”) with the Commission
to facilitate a public offering of its securities. The Lender agrees, for the benefit of the Company, that should such an initial public
offering be made and should the managing underwriter of such offering require, the Lender will not, without the prior written consent
of the Company and such underwriter, during the “Lockup Period” as defined herein: (i) sell, transfer or otherwise dispose
of, or agree to sell, transfer or otherwise dispose of any of the Warrant Shares beneficially owned by the Lender during the Lockup Period;
(ii) sell, transfer or otherwise dispose of, or agree to sell, transfer or otherwise dispose of any options, rights or warrants to
purchase any of the Warrant Shares beneficially owned by the Lender during the Lockup Period; or (iii) sell or grant, or agree to sell
or grant, options, rights or warrants with respect to any of the Warrant Shares. The foregoing does not prohibit gifts to donees or transfers
by will or the law of descent to heirs or beneficiaries provided that such donees, heirs and beneficiaries shall be bound by the
restrictions set forth herein. The term “Lockup Period” shall mean the lesser of (x) 180 days and (y) the period during which
Company officers and directors are restricted by the managing underwriter from effecting any sales or transfers of the Company’s
Common Stock. The Lockup Period shall commence on the effective date of the Registration Statement.

 

4.4 The Lender agrees that
the Company may place one or more restrictive legends on any certificates evidencing the Securities containing substantially the following
language:

 

The shares represented by this certificate have not been registered
under the Securities Act of 1933. As amended (the “Act”), or under the securities laws of any state or foreign jurisdiction
(“Other Laws”) in reliance upon the representation by the holder that they have been acquired for investment purposes only
and not with a view to resale or further distribution. Such shares may not be offered for sale, sold, delivered after sale, transferred,
pledged or hypothecated, nor will any assignee or endorsee hereof be recognized as an owner hereof by EPIEN Medical, Inc. for any purpose,
unless a registration statement under the Act and any applicable Other Law with respect to such shares shall then be in effect or unless
the availability of an exemption from registration shall be established to the satisfaction of counsel for the EPIEN Medical, Inc..

 

A full statement of the powers, designations, preferences and
relative, participating, optional or other special rights of each class of stock or series thereof of the corporation and the qualifications,
limitations or restrictions of such preferences and/or rights will be furnished by said corporation to any stockholder upon request and
without charge.

 

4.5 The Lender agrees that
the Company may place a stop transfer order with its registrar and transfer agent (if any) covering all Securities.

 

4.6 The Lender understands
that the Securities are not freely transferable and may in fact be prohibited from sales for an extended period of time and that, as a
consequence thereof, the Lender must bear the economic risk of an investment in the Securities for an indefinite period of time and may
have extremely limited opportunities to dispose of the Securities. The Lender realizes that there will likely be no market for the Securities,
and that there are significant restrictions on transferability thereof.

 

4.7 The Lender understands
and acknowledges that the Company has no obligation to undertake or complete a public offering of its securities, that even if a public
offering is undertaken and successfully completed, the Securities subscribed for hereby will remain subject to restrictions on transferability
described herein, and that even if a public offering is undertaken and completed, the Lender may never be able to sell its Securities
pursuant to Rule 144 under the Act.

 

4.8 The Lender further understands
and acknowledges that the Company currently does not file periodic reports with the Commission pursuant to the requirements of Section
13 or 15(d) of the Exchange, and may not be obligated to file such reports at any time in the future. The Lender also understands that
the Company has not agreed to supply such other information as would be required to enable routine sales of the Securities to be made
under the provisions of certain rules respecting “restricted securities,” including Rule 144 promulgated under the
Act by the Commission. Thus, the Lender has been informed that the Company is not obligated to make publicly available or to provide the
Lender with the information required by Rule 144.

 

    6

     

    

 

4.9 The Lender shall supply
such additional information and documentation relating to the Lender and any persons who have any rights or interest in the Lender as
may be requested by the Company in order to ensure compliance by the Company with applicable laws. If at any time prior to the Company’s
execution of this Agreement, an adverse change occurs with respect to the Lender such that the information, representations and warranties
of the Lender set forth in this Agreement are no longer accurate, the Lender shall immediately notify the Company of the inaccuracy in
writing and shall deliver the updated, accurate information to the Company.

PROMISSORY NOTE

 

	
    FIXED TERM CONVERTIBLE NOTE
	White Bear Lake, Minnesota
	 	 
	$_________	_______________

 

FOR VALUE RECEIVED, EPIEN Medical, Inc., a
Minnesota corporation (the “Company”), hereby promises to pay to the order of ______________ (an individual) with right
of survivorship (“Payee”), the principal sum of ___________________Dollars ($_______) (“Principal”),
together with interest as provided for herein.

 

This Promissory Note shall be subject to the following
terms and conditions and the terms and conditions contained in the Loan Agreement, dated the date hereof, between the Company and Payee
(the “Loan Agreement”):

 

SECTION 1

Terms

 

Interest Rate. The Company agrees to pay interest
on the outstanding Principal from the date of this Promissory Note until the Principal has been paid in full and at a fixed rate per annum
equal to _______ percent (___%). Such interest shall be computed on the basis of actual days elapsed and a year of 365 days, payable in
full on the Due Date.

 

Payment Date. The Company agrees that the
entire outstanding Principal, together with all interest accrued thereon, shall be due and payable in lawful money of the United States
of America in immediately available funds three year from the date hereof (“Due Date”), unless this Promissory Note shall
have been prepaid, upon presentation and surrender of this Promissory Note, duly endorsed in blank, at the principal office of the Company;
provided, however, that the Principal and all accrued interest of this Promissory Note may be converted into securities of the
Company, as provided in Section 2 hereof.

 

Default. If an Event of Default, as defined
in the Loan Agreement, shall have occurred and be continuing, Payee may, at Payee’s option, exercise any right, power or remedy
permitted to it by law and shall have, in particular, without limitation on the foregoing, the right to declare the entire unpaid Principal
of this Promissory Note and interest accrued thereon to be due and payable, without any presentment, demand, protest, or other notice
of any kind, all of which are hereby expressly waived.

 

    10

     

    

 

Prepayment. The Company may prepay the Principal
of this Promissory Note in whole at any time without premium or penalty upon not less than fifteen (15) days advance written notice to
Payees. The Company may prepay in whole or in part an interest due under the Promissory Note without notice.

 

Related Promissory Notes. This Promissory
Note is one of a series of Promissory Notes (collectively, the “Notes”), all of which are substantively similar to this Promissory
Note.

 

SECTION 2

Convertibility

 

Optional Conversion. At any time from and
after one year from the date hereof, Payee may elect to convert all of the then outstanding Principal and accrued but unpaid interest
due under this Promissory Note into shares of Common Stock of the Company, $0.01 par value per share (the “Common Stock”)
by giving written notice of such election on or prior to the Due Date. The conversion price per share for the shares of Common Stock purchased
by Payee pursuant to conversion of this Promissory Note shall equal a twenty-five percent (25%) discount of the current fair market value
of a share of the Common Stock as of the date of the conversion (the “Conversion Price”). In lieu of issuing fractional shares,
the Company shall pay all of the cash value of any fractional interest to Payee.

 

Fair Market Value. For purposes of this Section,
“Fair Market Value” means (i) if the Common Stock is listed or admitted to unlisted trading privileges on any national securities
exchange or is not so listed or admitted but transactions in the Common Stock are reported on the Nasdaq National Market, the reported
closing price of the Common Stock on such exchange or by the Nasdaq National Market as of such date (or, if no shares were traded on such
days, as of the next preceding day on which there was such a trade); or (ii) if the Common Stock is not so listed or admitted to unlisted
trading privileges or reported on the Nasdaq National Market, and bid and asked prices therefore in the over-the-counter market are reported
by the Nasdaq system or National Quotation Bureau, Inc. (or any comparable reporting system), the mean of the closing bid and asked prices
as of such date, as so reported by the Nasdaq system, or, if not so reported thereon, as reported by National Quotation Bureau, Inc. (or
such comparable reporting service); or (iii) if the Common Stock is not so listed or admitted to unlisted trading privileges, or reported
on the Nasdaq National Market, and such bid and asked prices are not so reported by the Nasdaq system or National Quotation Bureau, Inc.
(or any comparable reporting service), such price as the Company’s Board of Directors determines in good faith in the exercise of
its reasonable discretion.

 

Mandatory Conversion. At any time from and
after one year from the date hereof, or as of and from such earlier date as the Company’s Board of Directors shall determine in
its sole discretion, all of the then outstanding Principal and accrued but unpaid interest due under this Promissory Note shall automatically
convert to Common Stock at the Conversion Price immediately prior to the occurrence of any of the following: i) a merger in which the
shareholders of the Company prior to the merger hold less than 50% of the voting power of the capital stock of the surviving corporation
after such merger, a sale of all of the assets of the Company or a transaction or series of transactions in which 50% or more of the voting
power of the capital stock of the Company is transferred; or ii) the closing of an initial public offering of the Company’s equity
securities pursuant to an effective registration statement under the Securities Act of 1933, as amended.

 

    11

     

    

 

SECTION 3

______ shares of Common Stock of the Company at an exercise price of $_____ per share:

 

The form of any warrant issued pursuant to this Section 3 shall be
the attached Exhibit A.

 

SECTION 4

Miscellaneous

 

Transferability. Other than pursuant to registration
under federal and any applicable state securities laws or an exemption from such registration, this Promissory Note may not be sold, pledged,
assigned, or otherwise disposed of (whether voluntarily or involuntarily) by Payee unless the Company receives from the transferee such
representations and agreements as the Company may determine in its sole discretion to be necessary and appropriate to permit such transfer
to be made pursuant to exemptions from registration under federal and applicable state securities laws. Each certificate representing
this Promissory Note shall bear appropriate legends setting forth these restrictions on transfer.

 

Benefit of Promissory Note. This Promissory
Note shall be binding upon, and shall inure to the benefit of and be enforceable by Payee and its successors and assigns.

 

Costs. The Company hereby waives presentment
for payment, notice of dishonor, protest and notice of protest and, in the event this Promissory Note is not paid in full by the date
required in Section 1, the Company shall pay all of Payee’s costs of collection, including but not limited to, all reasonable attorneys’
fees.

 

Governing Law and Construction. This Promissory
Note shall be construed in accordance with and governed by the laws of the State of Minnesota. Whenever possible, each provision of this
Promissory Note and any other statement, instrument or transaction contemplated hereby and valid under such applicable law, but, if any
provision of this Promissory Note or any other statement, instrument or transaction contemplated hereby or relating hereto shall be held
to be prohibited or invalid under such applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity,
without invalidating the remainder of such provision or the remaining provisions of this Promissory Note or any other statement, instrument
or transaction contemplated hereby or relating hereto. In the event of any conflict with, between or among the provisions of this Promissory
Note or any other statement, instrument, or transaction contemplated or relating hereto those provisions giving Payee the greater right
shall govern.

Exhibit A

WARRANT

FOR

SHARES OF EQUITY SECURITIES

OF

EPIEN MEDICAL, INC.

 

For value received, __________, or its successors
or assigns (“Holder”), is entitled to subscribe for and purchase from EPIEN Medical, Inc., a Minnesota corporation (the “Company”),
up to _________ (_________________) fully paid and nonassessable shares of the Company’s Common Stock, par value $0.01
per share (“Equity Securities”), or such greater or lesser number of such shares as may be determined by application of the
anti-dilution provisions of this warrant, at ___________ ($________) per share, subject to adjustments as noted below (the “Warrant
Exercise Price”).

 

This warrant may be exercised by Holder at any time
or from time to time on or prior to the ________ anniversary of the date hereof.

 

This warrant is subject to the following provisions,
terms and conditions:

 

1. (a) The rights represented by this warrant
may be exercised by Holder, in whole or in part, by written notice of exercise delivered to the Company at least twenty (20) days prior
to the intended date of exercise and by the surrender of this warrant (properly endorsed if required), together with the exercise form
attached hereto, at the principal office of the Company and upon payment to it by cash, certified check or bank draft of the purchase
price for such shares. For each partial exercise, Holder shall purchase a minimum of one thousand (1,000) shares, or, if the number of
shares available for exercise under this warrant is less than such minimum number, the balance of the shares available for exercise under
this warrant. The shares so purchased shall be deemed to be issued immediately prior to the close of business on the date the Company
receives this warrant, a completed exercise form, all documents the Company may reasonably request from Holder for the purpose of complying
with applicable securities and other laws, and payment for the number of shares being acquired upon exercise of this warrant. Certificates
for the shares of stock so purchased, bearing the restrictive legend set forth at the end of this warrant, shall be delivered to Holder
after the rights represented by this warrant shall have been so exercised, and, unless this warrant has expired, a new warrant representing
the number of shares, if any, with respect to which this warrant has not been exercised shall also be delivered to Holder. No fractional
shares shall be issued upon the exercise of this warrant.

 

(b) In
lieu of payment, the rights represented by this warrant may also be exercised by a written notice of exercise delivered to the Company
at least fifteen (15) business days prior to the intended date of exercise specifying that Holder wishes to convert all or part of this
warrant into that number of shares of the Equity Securities as follows: the number of shares of the Equity Securities equal to the quotient
of: (i) the difference between (A) the Per Share Price (as defined hereinafter) of the Equity Securities, less (B) the Warrant Exercise
Price then in effect, multiplied by the number of shares of Equity Securities Holder would otherwise have been entitled to purchase hereunder
pursuant to clause (a) of this Section 1 (or such lesser number of shares Holder may designate in the case of a partial exercise of this
warrant); over (ii) the Per Share Price. Such conversion shall be exercised with respect to not less than the lesser of one thousand (1,000)
shares, or the balance of shares available upon exercise or conversion of this warrant.

 

    14

     

    

 

(c) For
purposes of clause (b) this Section 1, “Per Share Price” means (i) if the Equity Securities are listed or admitted to unlisted
trading privileges on any national securities exchange or are not so listed or admitted but transactions in the Equity Securities are
reported on the Nasdaq National Market, the reported closing price of the Equity Securities on such exchange or by the Nasdaq National
Market as of such date (or, if no shares were traded on such days, as of the next preceding day on which there was such a trade); or (ii)
if the Equity Securities are not so listed or admitted to unlisted trading privileges or reported on the Nasdaq National Market, and bid
and asked prices therefore in the over-the-counter market are reported by the Nasdaq system or National Quotation Bureau, Inc. (or any
comparable reporting system), the mean of the closing bid and asked prices as of such date, as so reported by the Nasdaq system, or, if
not so reported thereon, as reported by National Quotation Bureau, Inc. (or such comparable reporting service); or (iii) if the Equity
Securities are not so listed or admitted to unlisted trading privileges, or reported on the Nasdaq National Market, and such bid and asked
prices are not so reported by the Nasdaq system or National Quotation Bureau, Inc. (or any comparable reporting service), such price as
the Company’s Board of Directors determines in good faith in the exercise of its reasonable discretion.

 

2. (a) If, at any time during the period beginning
on the date six (6) months after the closing of an initial public offering of the Company’s equity securities, which offering generates
gross proceeds of not less than $5,000,000 and is underwritten on a “firm” basis (“Initial Public Offering”),
the Company proposes to register the sale of any of its shares of Common Stock under the Securities Act of 1933, as amended (the “Act”),
on any registration form which permits resales of securities by security holders of the Company, the Company will give written notice
to Holder of its intention to do so and, upon the written request of Holder received by the Company within fifteen (15) days after delivery
by the Company of any such notice, the Company will act to cause all Equity Securities for which Holder shall have requested the registration
or qualification thereof, to be included in such registration statement proposed to be filed by the Company.

 

 (b) If any such registration shall be underwritten
in whole or in part, the Company may require that the Equity Securities requested for inclusion pursuant to this Section be included in
the underwriting on the same terms and conditions as the securities otherwise being sold through the underwriters. In the event that,
in the good faith judgment of the managing underwriter of such public offering, the inclusion of all of the Equity Securities originally
covered by a request for registration would reduce the number of shares to be offered by the Company or interfere with the successful
marketing of the shares of Common Stock offered in the underwritten offering, the number of Equity Securities requested to be included
pursuant to this Section in the underwritten public offering may be reduced at the discretion of such underwriter.

 

    15

     

    

 

 (c) Any costs and expenses related to any
registration pursuant to this Section shall be borne by the Company, provided, that Holder shall bear expenses including,
but not limited to, underwriting commissions applicable to its shares, fees of its legal counsel and fees and expenses relating
to qualifications under state securities or blue sky laws incurred by the Company on behalf of Holder.

 

 (d) Notwithstanding anything herein to the
contrary, the Company may delay filing a registration statement, and may withhold efforts to cause the registration statement to become
effective, if the Company determines in good faith that such registration might adversely affect the Company.

 

 (e) The Company shall keep effective and maintain
any registration, qualification, notification or approval specified in this Section, with respect to Holder, only for such period as the
Company shall be obligated to maintain effectiveness of the underlying registration statement. If, after the registration statement becomes
effective, the Company advises Holder that the Company considers it appropriate for the registration statement or any prospectus related
thereto to be amended, Holder shall immediately suspend any further sales of its registered shares until the Company advises it that the
registration statement or prospectus has been amended.

 

 (f) Holder shall furnish in writing to the
Company all information as may be reasonably requested by the Company or required under applicable securities law in connection with any
registration of Equity Securities including, but not limited to, the proposed method of sale or other disposition of the
registered shares and any compensation payable in connection therewith. Holder shall comply with the provisions of applicable securities
law in connection with the registration of shares and the disposition thereof.

 

 (g) In connection with any registration statement
in which the Equity Securities are included, Holder shall indemnify the Company, its directors and officers and each person who controls
the Company, against any losses, claims, damages, liabilities and expenses resulting from any untrue or alleged untrue statement of material
fact contained in the registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any
omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading.

 

 (h) The Company’s obligation to include
the Equity Securities in a registration under this Section shall terminate on the earlier of the close of business on the date three (3)
years from the date of this warrant or the date on which, in the opinion of legal counsel to the Company, the Equity Securities may be
transferred within a 90-day period, or reissued without restriction, in compliance with the provisions of Rule 144 under the Act,
or any successor provision.

 

    16

     

    

 

3. (a) For purposes of this Section, a “Change
in Control” of the Company will mean (i) the sale, lease, exchange or other transfer of substantially all of the assets of the Company
(in one transaction or in a series of related transactions) to a person or entity that is not controlled, directly or indirectly, by the
Company, (ii) a merger or consolidation to which the Company is a party if the shareholders of the Company immediately prior to effective
date of such merger or consolidation do not have “beneficial ownership” (as defined in Rule 13d-3 under the Exchange Act of
1934, as amended (the “Exchange Act”)) immediately following the effective date of such merger or consolidation of more than
80% of the combined voting power of the surviving corporation’s outstanding securities ordinarily having the right to vote at elections
of directors, or (iii) a change in control of the Company of a nature that would be required to be reported pursuant to Section 13 or
15(d) of the Exchange Act, whether or not the Company is then subject to such reporting requirements, including, without limitation,
such time as any person becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly,
of 50% or more of the combined voting power of the Company’s outstanding securities ordinarily having the right to vote at elections
of directors.

 

(b) If a
Change in Control of the Company occurs, this warrant will immediately be exercised in full, without any action required by Holder, and
the Company shall deliver to Holder the number of shares of the Equity Securities equal to the value of the warrant, or any portion thereof
if some portion was previously exercised in part, at the time the Change of Control occurs (determined by finding the quotient of: (i)
the difference between (A) the Per Share Price of the Equity Securities immediately prior to the Change in Control, less (B) the Warrant
Exercise Price in effect immediately prior to the Change in Control, multiplied by the number of shares of Equity Securities that Holder
would otherwise have been entitled to purchase hereunder pursuant to clause (a) of Section 1; over (ii) the Per Share Price).

 

4. The Company
covenants and agrees that all shares that may be issued upon the exercise of the rights represented by this warrant shall, upon issuance,
be duly authorized and issued, fully paid and nonassessable shares. The Company further covenants and agrees that during the period within
which the rights represented by this warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose
of issue or transfer upon exercise of the subscription rights evidenced by this warrant, a sufficient number of shares of Common Stock.

 

5. The Warrant
Exercise Price shall be subject to adjustment from time to time as hereinafter provided in this section 5.

 

(a) If the
Company at any time divides the outstanding shares of its Common Stock into a greater number of shares (whether pursuant to a stock split,
stock dividend or otherwise), and conversely, if the outstanding shares of its Common Stock are combined into a smaller number of shares,
the Warrant Exercise Price in effect immediately prior to such division or combination shall be proportionately adjusted to reflect the
reduction or increase in the value of the Common Stock.

 

(b) If any
capital reorganization or reclassification of the capital stock of the Company, or consolidation or merger of the Company with another
corporation, or the sale of all or substantially all of its assets to another corporation shall be effected in such a way that Holder
shall be entitled to receive stock, securities or assets with respect to or in exchange for the Equity Securities, then, as a condition
of such reorganization, reclassification, consolidation, merger or sale, Holder shall have the right to purchase and receive upon the
basis and upon the terms and conditions specified in this warrant and in lieu of the shares of the Equity Securities immediately theretofore
purchasable and receivable upon the exercise of the rights represented hereby, such shares of stock, other securities or assets as would
have been issued or delivered to Holder if it had exercised this warrant and had received such shares of Equity Securities prior to such
reorganization, reclassification, consolidation, merger or sale. The Company shall not effect any such consolidation, merger or sale,
unless prior to the consummation thereof the successor corporation (if other than the Company) resulting from such consolidation or merger
or the corporation purchasing such assets shall assume by written instrument executed and mailed to the registered Holder at the last
address of such Holder appearing on the books of the Company, the obligation to deliver to such Holder such shares of stock, securities
or assets as, in accordance with the foregoing provisions, such Holder may be entitled to purchase.

 

    17

     

    

 

(c) Upon
each adjustment of the Warrant Exercise Price, Holder shall thereafter be entitled to purchase, at the Warrant Exercise Price resulting
from such adjustment, the number of shares obtained by multiplying the Warrant Exercise Price in effect immediately prior to such adjustment
by the number of shares purchasable pursuant hereto immediately prior to such adjustment and dividing the product thereof by the Warrant
Exercise Price resulting from such adjustment.

 

(d) Upon
any adjustment of the Warrant Exercise Price, the Company shall give written notice thereof, by first class mail, postage prepaid, addressed
to the registered Holder of this warrant at the address of such Holder as shown on the books of the Company, which notice shall state
the Warrant Exercise Price resulting from such adjustment and the increase or decrease, if any, in the number of shares purchasable at
such price upon the exercise of this warrant, setting forth in reasonable detail the method of calculation and the facts upon which such
calculation is based.

 

6. This
warrant shall not entitle Holder to any voting rights or other rights as shareholders of the Company.

 

7. (a) Holder, by acceptance hereof, agrees
to give written notice to the Company before transferring this warrant or transferring any shares of the Company’s Equity Securities
issuable or issued upon the exercise of this warrant of Holder’s intention to do so, describing briefly the manner of any proposed
transfer of this warrant or such Holder’s intention as to the shares of Equity Securities issuable upon the exercise hereof or the
intended disposition to be made of shares of Equity Securities upon such exercise. Promptly upon receiving such written notice, the Company
shall present copies thereof to counsel for the Company. If, in the opinion of such counsel, the proposed transfer of this warrant or
disposition of shares may be effected without registration or qualification (under any federal or state law) of this warrant or the shares
of Equity Securities issuable or issued upon the exercise hereof, the Company, as promptly as practicable, shall notify such Holder of
such opinion, whereupon such Holder shall be entitled to transfer this warrant, or to exercise this warrant in accordance with its terms
and dispose of the shares received upon such exercise or to dispose of shares of Equity Securities received upon the previous exercise
of this warrant, all in accordance with the terms of the notice delivered by such Holder to the Company, provided that an appropriate
legend in substantially the form set forth at the end of this warrant respecting the foregoing restrictions on transfer and disposition
may be endorsed on this warrant or the certificates for such shares.

 

    18

     

    

 

 (b) If the Company conducts an initial public
offering of its Common Stock, Holder shall not, without the prior written consent of the Company and the managing underwriter in such
offering: (i) sell, transfer or otherwise dispose of, or agree to sell, transfer or otherwise dispose of any of the Equity Securities;
(ii) sell, transfer or otherwise dispose of, or agree to sell, transfer or otherwise dispose of any right to purchase any of the Equity
Securities; or (iii) sell or grant, or agree to sell or grant, options, rights or warrants with respect to any of the Equity Securities.
Such restrictions shall be effective for a period of time equal to the period during which the managing underwriter imposes such transfer
restrictions on the Company’s officers and directors; provided, that in no event shall the restricted period applicable to
Holder exceed one hundred eight (180) days after effectiveness of the Company’s registration statement filed with the Securities
and Exchange Commission with respect to such offering.

 

8. Subject
to the provisions of section 7, this warrant and all rights hereunder are transferable, in whole or in part, at the principal office of
the Company by Holder in person or by duly authorized attorney, upon surrender of a form of assignment as attached and this warrant properly
endorsed to any person or entity who represents in writing that he/she/it is acquiring the warrant for investment and without any view
to the sale or other distribution thereof. Each Holder of this warrant, by taking or holding the same, consents and agrees that the bearer
of this warrant, when endorsed, may be treated by the Company and all other persons dealing with this warrant as the absolute owner hereof
for any purpose and as the person entitled to exercise the rights represented by this warrant, or to the transfer hereof on the books
of the Company, any notice to the contrary notwithstanding; but until such transfer on such books, the Company may treat the registered
owner hereof as the owner for all purposes.

 

9. At the
request of Holder in connection with a transfer or exercise of a portion of the warrant, upon surrender of the warrant for such purpose
to the Company, the Company will issue and exchange warrants of like tenor and date representing in the aggregate the right to purchase
such number of shares of Common Stock as shall be designated by Holder at the time of such surrender, provided, however, that the Company’s
obligations to subdivide securities under this Section shall be subject to and conditioned upon the compliance of any such subdivision
with applicable securities laws.

 

10. Neither
this warrant nor any term hereof may be changed, waived, discharged or terminated orally but only by an instrument in writing signed by
the party against which enforcement of the change, waiver, discharge or termination is sought.

 

    19
