COMMUNITY BANK-WHEATON/GLEN ELLYN 

DIRECTORS RETIREMENT PLAN 

 

The Board of Directors
of Community Bank-Wheaton/Glen Ellyn (the “Bank”) adopted the Community Bank Directors Retirement Plan, effective December
31, 2008, in order to recognize the contributions of its directors to the success of the
Bank, as well as to encourage the continued contributions of the directors to the Bank’s long-term success.

 

This document (the “409A
Program”) amends and restates the Plan effective as of January 1, 2005, and it sets forth the terms of the Plan applicable
to vested benefits subject to Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), i.e., vested
benefits accrued after December 31, 2004.

 

Other vested benefits
under the Plan shall be governed by a separate document that sets forth the pre-Section 409A terms of the Plan (the “Pre-409A
Program”). Together, this document and the document for the Pre-409A Program describe the terms of a single plan. However,
amounts subject to the terms of this 409A Program and amounts subject to the terms of the Pre-409A Program shall be tracked separately
at all times. The preservation of the terms of the Pre-409A Program, without material modification, and the separation between
the 409A Program amounts and the Pre-409A Program amounts are intended to permit the Pre-409A Program to remain exempt from Section
409A, and the administration of the Plan shall be consistent with this intent.

sum payment, the monthly installments shall be discounted to the lump sum payment date, using a discount rate of six (6) percent.
Notwithstanding the foregoing, the Participant’s benefit shall automatically be paid in a lump sum as soon as practicable
following the Participant’s Separation from Service if (i) the Participant has failed to timely make an election for the
payment of the benefit, or (ii) the value of the Participant’s Account as of the date of the Participant’s Separation

31, 2008, the Bank shall pay to the Participant the benefit described in this Section 3.2.

 

3.2.1      Amount of Benefit. The benefit under this
Section 3.2 is the Account balance (which shall vest 100% upon a Change in Control) at the Change in Control.

 

3.2.2      Payment of Benefit. The Bank shall pay
the benefit under this Section 3.2 to the Participant in accordance with the Participant’s prior valid election (i) in a
lump sum as soon as practicable following the Change in Control or (ii) as an annual benefit in one hundred twenty (120) equal
monthly installments on the first day of each month commencing with the month following the Change in Control. For purposes of
determining the amount of a lump sum payment, the monthly installments shall be discounted to the lump sum payment date, using
a discount rate of six (6) percent. Notwithstanding the foregoing, the Participant’s benefit shall automatically be paid
in a lump sum as soon as practicable following the Change in Control if the value of the Participant’s Account as of the
date of the Change in Control is ten thousand dollars ($10,000) or less.

 

3.3          Death During Active Service. If the
Participant dies while in active service of the Bank, the Bank shall pay to the participant’s beneficiary the benefit described
in this Section 3.3.

 

3.3.1       Amount of Benefit. The benefit under this
Section 3.3 is the vested account balance at the date of the Participant’s death.

3.4          Death During Benefit Period. If the

shall pay the remaining benefits to the Participant’s beneficiary at the same time and in the same amounts they would have
been paid to the Participant had the Participant survived.

 

3.5          Disability. If a Participant incurs
a Disability prior to a Separation from Service, the Bank shall pay his vested Account to him in one hundred (120) equal monthly

by completing a payment election form, provided that any such election (i) must be made prior to the Participant’s Separation
form Service, (ii) shall not take effect before the date that is 12 months after the date the election is made, (iii) cannot apply
to amounts that would otherwise be payable in 2008 and may not cause an amount to be paid in 2008 that would otherwise be paid

Miscellaneous

 

6.1         Binding Effect. This Plan shall bind
each participating Participant and the Bank and their respective beneficiaries, survivors, executors, administrators and transferees.

 

6.2         No Guarantee of Service. This Plan
is not a contract for service. It does not give a Participant the right to remain in the service of the Bank, nor does it interfere
with the Bank’s right to replace a Participant. It also does not require a Participant to remain in the service of the Bank
nor interfere with the Participant’s right to terminate service at any time.

 

6.3         Non-Transferability. Benefits under
this Plan cannot be sold, transferred, assigned, pledged, attached or encumbered in any manner.

 

6.4         Tax Withholding. The Bank shall withhold
any taxes that are required to be withheld from the benefits provided under this Plan.

 

6.5         Applicable Law. The Plan and all rights
hereunder shall be governed by the laws of Illinois, except to the extent preempted by federal law.

 

6.6         Unfunded Arrangement. Each Participant
and any beneficiary of such Participant are general unsecured creditors of the Bank for the payment of benefits under this Plan.
The benefits represent the mere promise by the Bank to pay such benefits. The rights to benefits are not subject in any manner
to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment, or garnishment by creditors. Any insurance
on a Participant’s life is a general asset of the Bank to which the Participant and the Participant’s beneficiary have
no preferred or secured claim.

 

6.7         Reorganization. The Bank shall not
merge or consolidate into or with another entity, or reorganize, or sell substantially all of its assets to another entity, firm,
or person unless such succeeding or continuing entity, firm, or person agrees to assume and discharge the obligations of the Bank
under this Plan. Upon the occurrence of such event, the term “Bank” as used in this Plan shall be deemed to refer to
the successor or survivor entity.

 

6.8         Entire Agreement. This Plan constitutes
the entire agreement between the Bank and a participating Participant as to the subject matter hereof. No rights are granted to
a Participant by virtue of this Plan other than those specifically set forth herein.

 

6.9         Administration. The Board of Directors
of the Bank shall have powers which are necessary to administer this Plan, including but not limited to:

 

(a)         Interpreting the provisions of the Plan;

 

(b)         Establishing and revising the method of accounting
for the Plan;

 

    	5

    	 

    

 

(c)         Maintaining a record of benefit payments; and

 

(d)         Establishing rules and prescribing any forms necessary
or desirable to administer the Plan.

 

6.10       Prohibited Acceleration/Distribution Timing.
This Section shall take precedence over any other provision of the Plan to the contrary. No provision of this Plan shall be followed
if following the provision would result in the acceleration of the time or schedule of any payment from the Plan (i) as would require
income tax to a Participant prior to the date on which the amount is distributable to or on behalf of the Participant under Article
3 or (ii) which would result in penalties to the Participant under Section 409A of the Code. In addition, if the timing of any
distribution election would result in any tax or other penalty (other than ordinarily payable Federal, state or local income or
payroll taxes), which tax or penalty can be avoided by payment of the distribution at a later time, then the distribution shall
be made (or commence, as the case may be) on (or as soon as practicable after) the first date on which such distributions can be
made (or commence) without such tax or penalty.

 

6.11       Aggregation of Employers. To the
extent required under Section 409A of the Code, if the Bank is a member of a controlled group of corporations or a group of trades
or business under common control (as described in Section 414(b) or (c) of the Code), all members of the group shall be treated
as a single employer for purposes of whether there has occurred a Separation from Service and for any other purposes under the
Plan as Section 409A of the Code shall require.

 

6.12       Designation of Beneficiary(ies).
Each Participant shall have the right to designate a beneficiary or beneficiaries (including contingent beneficiaries) to receive
any benefits payable upon the death of a Participant. No such designation shall be effective unless completed and submitted in
accordance with rules and procedures established by the Bank for this purpose. In the absence of an effective beneficiary designation,
the Participant’s designated beneficiary shall be assumed to be the Participant’s surviving spouse or, if none, the
Participant’s estate.

 

6.13       Consulting. The Participant agrees
that as long as he continues to receive payments hereunder and as long as he is physically and mentally able to do so. He will
consult with the Bank in an advisory capacity, in person if he is residing in the vicinity of Glen Ellyn, Illinois, and by telephone
and by mail if he shall not be residing in said vicinity when reasonably requested to do so by the Bank. The Bank and the Participant
agree that the Participant will render such consulting services as an independent contractor and shall receive a separate remuneration
when performing such services. If the Participant does not comply with this provision of the agreement, the Bank may, at its own
discretion, suspend, reduce, or terminate any or all of the benefits provided under this agreement for the benefit of the Participant
and his beneficiaries. It is intended that the amount of consulting services performed by the Participant shall not cause the Participant
not to have incurred a Separation from Service for purposes of Section 409A of the Code.

 

6.14       Compliance with Section 409A of the Code.
Despite any contrary provision of this Agreement, if, when a Participant’s service terminates, the Participant is a “specified
employee,” as defined in Section 409A of the Code, and if any payments under this Plan will result in additional tax or interest
to the Participant because of Section 409A of the Code, the Participant shall not be entitled to the such payments until the earliest
of (i) the date that is at least six months after termination of the Participant’s employment for reasons other than the
Participant’s death, (ii) the date of the Participant’s death, or (iii) any earlier date that does not result in additional
tax or interest to the Participant under Section 409A of the Code. If any provision of this Agreement would subject the Participant
to additional tax or interest under Section 409A of the Code, the Bank shall reform the provision. However, the Bank shall maintain
to the maximum extent practicable the original intent of the applicable provision without subjecting the Participant to additional
tax or interest.

1.2    The
Securities will be offered for sale until October 15, 2013 (the “Termination Date”). The Offering is being conducted
on a “best-efforts” basis. 

 

1.3    The
Company may hold an initial closing (“Initial Closing”) at any time prior to the Termination Date as determined by
the Company. After the Initial Closing, subsequent closings with respect to additional Securities may take place at any time prior
to the Termination Date as determined by the Company, with respect to subscriptions accepted prior to the Termination Date (each

or obtain a return of the subscription amount paid to the Company on or after the date of the Initial Closing. Any subscription
received after the Initial Closing but prior to the Termination Date shall be irrevocable. 

 

1.4    The
Subscriber recognizes that the purchase of the Securities involves a high degree of risk including, but not limited to, the following:
(a) the Company has a limited operating history and requires substantial funds in addition to the proceeds of the Offering; (b)
an investment in the Company is highly speculative, and only investors who can afford the loss of their entire investment should
consider investing in the Company and the Securities; (c) the Subscriber may not be able to liquidate its investment; (d) transferability
of the Securities is extremely limited; (e) in the event of a disposition, the Subscriber could sustain the loss of its entire
investment; (f) the Company has not paid any dividends since its inception and does not anticipate paying any dividends; and (g)
the other risks associated with the Company’s business, financial situation and the Offering set forth on Exhibit A
annexed hereto.

 

1.5    At
the time such Subscriber was offered the Securities, it was, and as of the date hereof it is, and on each date on which it converts
the Debentures and/or exercises any Warrants, it will be an “accredited investor” as defined in Rule 501(a) under
the Securities Act, as indicated by the Subscriber’s responses to the questions contained in Section VII hereof, and that
the Subscriber is able to bear the economic risk of an investment in the Securities.

 

1.6    The
Subscriber hereby acknowledges and represents that (a) the Subscriber has knowledge and experience in business and financial matters,
prior investment experience, including investment in securities that are non-listed, unregistered and/or not traded on a national
securities exchange or the Subscriber has employed the services of a “purchaser representative” (as defined in Rule
501 of Regulation D), attorney and/or accountant to read all of the documents furnished or made available by the Company both
to the Subscriber and to all other prospective investors in the Securities to evaluate the merits and risks of such an investment
on the Subscriber’s behalf; (b) the Subscriber recognizes the highly speculative nature of this investment; and (c) the
Subscriber is able to bear the economic risk that the Subscriber hereby assumes.

1.7    The
Subscriber hereby acknowledges receipt and careful review of this Agreement, the Debenture, the Warrant and all other exhibits
thereto (collectively referred to as the “Transaction Documents”) and has had access to the Company’s Annual
Report on Form 10-K and the exhibits thereto for the fiscal year ended December 31, 2012 (the “Form 10-K”), and the
Company’s Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2013 (the “Form 10-Q”) and
all subsequent periodic and current reports filed with the SEC as publicly filed with and available at the website of the SEC
which can be accessed at www.sec.gov, and has received any additional information that the Subscriber has requested from
the Company, and has been afforded the opportunity to ask questions of and receive answers from duly authorized officers or other
representatives of the Company concerning the Company and the terms and conditions of the Offering; provided, however that no
investigation performed by or on behalf of the Subscriber shall limit or otherwise affect its right to rely on the representations
and warranties of the Company contained herein. The Subscriber acknowledges that the Company has not filed all reports required
to be filed by it under the Securities Act and Securities Exchange Act of 1934, as amended (the “Exchange Act”), including
pursuant to Section 13(a) or 15(d) thereof.

 

1.8   
(a)          In making the decision to invest
in the Securities the Subscriber has relied solely upon the information provided by the Company in the Transaction Documents and
upon the information set forth in the Form 10-K, the Forms 10-Q and all subsequent periodic and current reports filed with the
SEC. To the extent necessary, the Subscriber has retained, at its own expense, and relied upon appropriate professional advice
regarding the investment, tax and legal merits and consequences of this Agreement and the purchase of the Securities hereunder.
The Subscriber disclaims reliance on any statements made or information provided by any person or entity in the course of Subscriber’s
consideration of an investment in the Securities other than the Transaction Documents.

1.9   The
Subscriber hereby acknowledges that the Offering has not been reviewed by the SEC nor any state regulatory authority since the
Offering is intended to be exempt from the registration requirements of Section 5 of the Securities Act, pursuant to Section 4(2)
of the Securities Act and Rule 506 of Regulation D. The Subscriber understands that the Securities have not been registered under
the Securities Act or under any state securities or “blue sky” laws and agrees not to sell, pledge, assign or otherwise
transfer or dispose of the Securities unless they are registered under the Securities Act and under any applicable state securities
or “blue sky” laws or unless an exemption from such registration is available.

 

1.10 The
Subscriber understands that the Securities have not been registered under the Securities Act by reason of a claimed exemption
under the provisions of the Securities Act that depends, in part, upon the Subscriber’s investment intention and investment
qualification. In this connection, the Subscriber hereby represents that the Subscriber is purchasing the Securities for the Subscriber’s
own account for investment and not with a view toward the resale or distribution to others; provided, however, that nothing contained
herein shall constitute an agreement by the Subscriber to hold the Securities for any particular length of time and the Company
acknowledges that the Subscriber shall at all times retain the right to dispose of its property as it may determine in its sole
discretion, subject to any restrictions imposed by applicable law. The Subscriber, if an entity, further represents that it was
not formed for the purpose of purchasing the Securities.

 

1.11 The
Subscriber consents to the placement of a legend on any certificate or other document evidencing the Securities and, when issued,
the shares of Common Stock issuable upon conversion of the Debentures (the “Conversion Shares”) and exercise of the
Warrant (the “Warrant Shares” and collectively with the Conversion Shares, the “Shares”) that such securities
have not been registered under the Securities Act or any state securities or “blue sky” laws and setting forth or
referring to the restrictions on transferability and sale thereof contained in this Agreement. The Subscriber is aware that the
Company will make a notation in its appropriate records with respect to the restrictions on the transferability of such Securities
or the Shares. 

 

1.12 The
Subscriber hereby represents that the address of the Subscriber furnished by Subscriber on the signature page hereof is the Subscriber’s
principal residence if Subscriber is an individual or its principal business address if it is a corporation or other entity.

1.13 Such

to or for distributing or reselling such Securities or any part thereof in violation of the Securities Act or any applicable state
securities law, has no present intention of distributing any of such Securities in violation of the Securities Act or any applicable
state securities law and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding
the distribution of such Securities in violation of the Securities Act or any applicable state securities law. Furthermore, such
Subscriber is not purchasing the Securities as a result of any advertisement, article, notice or other communication regarding
the Securities published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any
seminar or any other general solicitation or general advertisement.

 

1.14 The
Subscriber represents that the Subscriber has full power and authority (corporate, statutory and otherwise) to execute and deliver
this Agreement and to purchase the Securities. This Agreement constitutes the legal, valid and binding obligation of the Subscriber,
enforceable against the Subscriber in accordance with its terms.

 

1.15 If
the Subscriber is a corporation, partnership, limited liability company, trust, employee benefit plan, individual retirement account,
Keogh Plan, or other tax-exempt entity, it is authorized and qualified to invest in the Company and the person signing this Agreement
on behalf of such entity has been duly authorized by such entity to do so.

 

1.16 The
Subscriber acknowledges that if he or she is a Registered Representative of a Financial Industry Regulatory Authority (“FINRA”)
member firm, he or she must give such firm the notice required by the FINRA’s Rules of Fair Practice, receipt of which must
be acknowledged by such firm in Section 7.4 below.

 

1.17 The
Subscriber agrees not to issue any public statement with respect to the Offering, Subscriber’s investment or proposed investment
in the Company or the terms of any agreement or covenant between them and the Company without the Company’s prior written
consent, except such disclosures as may be required under applicable law.

 

1.18 The
Subscriber understands, acknowledges and agrees with the Company that this subscription may be rejected, in whole or in part,
by the Company, in the sole and absolute discretion of the Company, at any time before any Closing notwithstanding prior receipt
by the Subscriber of notice of acceptance of the Subscriber’s subscription.

 

1.19 The
Subscriber acknowledges that the information contained in the Transaction Documents or otherwise made available to the Subscriber
is confidential and non-public and agrees that all such information shall be kept in confidence by the Subscriber and neither
used by the Subscriber for the Subscriber’s personal benefit (other than in connection with this subscription) nor disclosed
to any third party for any reason, notwithstanding that a Subscriber’s subscription may not be accepted by the Company;
provided, however, that (a) the Subscriber may disclose such information to its affiliates and advisors who may have a need for
such information in connection with providing advice to the Subscriber with respect to its investment in the Company so long as
such affiliates and advisors have an obligation of confidentiality, and (b) this obligation shall not apply to any such information
that (i) is part of the public knowledge or literature and readily accessible at the date hereof, (ii) becomes part of the public
knowledge or literature and readily accessible by publication (except as a result of a breach of this provision) or (iii) is received
from third parties without an obligation of confidentiality (except third parties who disclose such information in violation of
any confidentiality agreements or obligations, including, without limitation, any subscription or other similar agreement entered
into with the Company).

1.20 Since
the time that such Subscriber was first contacted by the Company, neither the Subscriber nor any Affiliate of such Subscriber
which (x) had knowledge of the transactions contemplated hereby, (y) has or shares discretion relating to such Subscriber’s
investments or trading or information concerning such Subscriber’s investments, including in respect of the Securities,
and (z) is subject to such Subscriber’s review or input concerning such Affiliate’s investments or trading (collectively,
“Trading Affiliates”) has directly or indirectly, nor has any person acting on behalf of or pursuant to any understanding
with such Subscriber or Trading Affiliate, effected or agreed to effect any transactions in the securities of the Company (including,
without limitation, any short sales involving the Company’s securities). Notwithstanding the foregoing, in the case of a
Subscriber and/or Trading Affiliate that is, individually or collectively, a multi-managed investment vehicle whereby separate
portfolio managers manage separate portions of such Subscriber’s or Trading Affiliate’s assets and the portfolio managers
have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Subscriber’s
or Trading Affiliate’s assets, the representation set forth above shall apply only with respect to the portion of assets
managed by the portfolio managers that have knowledge about the financing transaction contemplated by this Agreement. Other than
to other persons party to this Agreement, such Subscriber has maintained the confidentiality of all disclosures made to it in
connection with this transaction (including the existence and terms of this transaction).

 

1.21 Subscriber
understands that the Securities being offered and sold to it in reliance on specific exemptions from the registration requirements
of United States federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and
such Subscriber’s compliance with, the representations, warranties, agreements, acknowledgements and understandings of such
Subscriber set forth herein in order to determine the availability of such exemptions and the eligibility of such Subscriber to
acquire the Securities.

 

1.22 Each
Subscriber hereunder acknowledges its primary responsibilities under the Securities Act and accordingly will not sell any of the
Securities or any interest therein without complying with the requirements of the Securities Act. In the event at any time a registration
statement covering the Securities remains effective, each Subscriber seeking to sell Securities thereunder agrees to sell the
Securities only in accordance with the plan of distribution contained in such registration statement and if it does so it will
comply therewith and with the related prospectus delivery requirements unless an exemption therefrom is available.

 

1.23 The
Subscriber will indemnify and hold harmless the Company and, where applicable, its directors, officers, employees, agents, advisors,
affiliates and shareholders, and each other person, if any, who controls any of the foregoing from and against any and all loss,
liability, claim, damage and expense whatsoever (including, but not limited to, any and all fees, costs and expenses whatsoever
reasonably incurred in investigating, preparing or defending against any claim, lawsuit, administrative proceeding or investigation
whether commenced or threatened) (a “Loss”) arising out of or based upon any representation or warranty of the Subscriber
contained herein or in any document furnished by the Subscriber to the Company in connection herewith being untrue in any material
respect or any breach or failure by the Subscriber to comply with any covenant or agreement made by the Subscriber herein or therein;
provided, however, that the Subscriber shall not be liable for any Loss that in the aggregate exceeds the Subscriber’s
aggregate purchase price tendered hereunder.

                                         BY AND COVENANTS OF THE COMPANY

 

The
Company hereby represents and warrants to the Subscriber that:

 

2.1    Organization,
Good Standing and Qualification. The Company is a corporation duly organized, validly existing and in good standing under
the laws of the State of Minnesota and has full corporate power and authority to own and use its properties and its assets and
conduct its business as currently conducted. Each of the Company’s subsidiaries identified on Schedule 2.1 hereto
(the “Subsidiaries”) is an entity duly organized, validly existing and in good standing under the laws of the jurisdiction
of its incorporation with the requisite corporate power and authority to own and use its properties and assets and to conduct
its business as currently conducted. Neither the Company, nor any of its Subsidiaries is in violation of any of the provisions
of their respective articles of incorporation, by-laws or other organizational or charter documents, including, but not limited
to the Charter Documents (as defined below). Each of the Company and its Subsidiaries is duly qualified to conduct business and
is in good standing as a foreign corporation in each jurisdiction in which the nature of the business conducted or property owned
by it makes such qualification necessary, except where the failure to be so qualified or in good standing, as the case may be,
would not result in a direct and/or indirect (i) material adverse effect on the legality, validity or enforceability of any
of the Securities and/or this Agreement, (ii) material adverse effect on the results of operations, assets, business, condition
(financial and other) or prospects of the Company and its Subsidiaries, taken as a whole, or (iii) material adverse effect on
the Company’s ability to perform in any material respect on a timely basis its obligations under the Transaction Documents
(any of (i), (ii) or (iii), a “Material Adverse Effect”).

 

    	5

    	 

    

 

2.2    Capitalization
and Voting Rights. The authorized, issued and outstanding capital stock of the Company is as set forth in Schedule 2.2
hereto and all issued and outstanding shares of capital stock of the Company are validly issued, fully paid and non-assessable.
Except as set forth in Schedule 2.2 hereto, (i) there are no outstanding securities of the Company or any of its Subsidiaries
which contain any preemptive, redemption or similar provisions, nor is any holder of securities of the Company or any Subsidiary
entitled to preemptive or similar rights arising out of any agreement or understanding with the Company or any Subsidiary by virtue
of any of the Transaction Documents, and there are no contracts, commitments, understandings or arrangements by which the Company
or any of its Subsidiaries is or may become bound to redeem a security of the Company or any of its Subsidiaries; (ii) neither
the Company nor any Subsidiary has any stock appreciation rights or "phantom stock" plans or agreements or any similar

into shares of capital stock of the Company or any Subsidiary. Except as set forth in Schedule 2.2 and as otherwise required
by law, there are no restrictions upon the voting or transfer of any of the shares of capital stock of the Company pursuant to
the Company’s Charter Documents (as defined below) or other governing documents or any agreement or other instruments to
which the Company is a party or by which the Company is bound. All of the issued and outstanding shares of capital stock of the
Subsidiaries are validly issued, fully paid and non-assessable and are owned by the Company, free and clear of any mortgages,
pledges, liens, claims, charges, encumbrances or other restrictions (collectively, “Encumbrances”). All of such outstanding
capital stock has been issued in compliance in all material respects with applicable federal and state securities laws. The issuance
and sale of the Securities and, upon issuance, the Shares, as contemplated hereby will not obligate the Company to issue shares
of Common Stock or other securities to any other person (other than the Subscriber) and except as set forth in Schedule 2.2 will
not result in the adjustment of the exercise, conversion, exchange or reset price of any outstanding security. The Company does
not have outstanding shareholder purchase rights or “poison pill” or any similar arrangement in effect giving any
person the right to purchase any equity interest in the Company upon the occurrence of certain events.

 

2.3    Authorization;
Enforceability. The Company has the requisite corporate right, power and authority to enter into, execute and deliver this
Agreement and each other agreement, document, instrument and certificate to be executed by the Company in connection with the
consummation of the transactions contemplated hereby, including, but not limited to Transaction Documents and to perform fully
its obligations hereunder and thereunder. All necessary corporate action on the part of the Company, its directors and shareholders

and the performance of the Company’s obligations under this Agreement and the Transaction Documents has been taken. This
Agreement and the Transaction Documents have been duly executed and delivered by the Company and each constitutes a legal, valid
and binding obligation of the Company, enforceable against the Company in accordance with its respective terms, subject to laws
of general application relating to bankruptcy, insolvency and the relief of debtors and rules of law governing specific performance,
injunctive relief or other equitable remedies, and to limitations of public policy. The Securities are duly authorized and, when
issued and paid for in accordance with the applicable Transaction Documents, will be duly and validly issued, fully paid and non-assessable,
free and clear of all Encumbrances other than restrictions on transfer provided for in the Transaction Documents. The Shares,
when issued and paid for in accordance with the terms of the Transaction Documents, will be validly issued, fully paid and non-assessable,
free and clear of all Encumbrances imposed by the Company other than restrictions on transfer provided for in the Transaction
Documents. The Company has reserved a sufficient number of Conversion Shares and Warrant Shares for issuance upon the conversion
of the Debentures and exercise of the Warrants, respectively, free and clear of all Encumbrances, except for restrictions on transfer
set forth in the Transaction Documents or imposed by applicable securities laws. Except as set forth on Schedule 2.3 hereto,
the issuance and sale of the Securities (including the Shares) contemplated hereby will not give rise to any preemptive rights
or rights of first refusal on behalf of any person other than the Subscribers.

		V.	COVENANTS
                                         OF THE PARTIES

 

5.1    Transfer
Restrictions.

 

(a)          The
Securities may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of Securities
other than pursuant to an effective registration statement or Rule 144 promulgated under the Securities Act, to the Company or
to an affiliate of a Subscriber or in connection with, the Company may require the transferor thereof to provide to the Company
an opinion of counsel selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion
shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred
Securities under the Securities Act. As a condition of transfer, any such transferee shall agree in writing to be bound by the
terms of this Agreement, and shall have the rights of a Subscriber under this Agreement.

 

(b)          The
Subscriber agrees to the imprinting, so long as is required by this Section 5.1, of a legend on any of the Securities, including
the Shares, substantially in the following form:

 

[NEITHER] THIS
SECURITY [NOR THE SECURITIES INTO WHICH THIS SECURITY IS [EXERCISABLE] [CONVERTIBLE]] HAS [NOT] BEEN REGISTERED WITH THE SECURITIES
AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES
ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD OR OTHERWISE TRANSFERRED,
PLEDGED OR HYPOTHECATED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE
EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH
APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF
WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY.

 

    	12

    	 

    

 

(c)          Certificates
evidencing the Shares shall not be required to contain any legend (including the legend set forth in Section 5.1(b) hereof): (i)
while a registration statement covering the resale of such security is effective under the Securities Act, or (ii) following any
sale of such Shares pursuant to Rule 144, or (iii) if such Shares are eligible for sale under Rule 144, without the requirement
for the Company to be in compliance with the current public information required under Rule 144 as to such Shares and without
volume or manner-of-sale restrictions. Upon request by a Subscriber in the event the foregoing permits removal of any legend from
certificates evidencing the Shares, the Company shall cause its counsel, at the Company’s expense, to issue a legal opinion
to the Company’s transfer agent promptly (but in no event later than the requisite share delivery date set forth in the
Debenture and the Warrant) if required by the Company’s transfer agent to effect the removal of the legend hereunder.

 

5.2    Listing
of Securities. The Company agrees, (i) if the Company applies to have the Common Stock traded on any other trading market,
it will include in such application the Shares, and will take such other action as is necessary or desirable to cause the Shares
to be listed on such other trading market as promptly as possible, and (ii) during the three-year period from and after the Final
Closing it will take all action reasonably necessary to continue the listing and trading of its Common Stock on a Trading Market
(as defined in the Debenture) and will comply in all material respects with the Company’s reporting, filing and other obligations
under the bylaws or rules of any such Trading Market (as defined in the Debenture).

 

5.3    Reservation
of Shares. The Company shall at all times while the Debenture and/or Warrants are outstanding maintain a reserve from its
duly authorized shares of Common Stock of a number of shares of Common Stock sufficient to allow for the issuance of the Shares.

 

5.4    Replacement
of Securities. If any certificate or instrument evidencing any Securities or the Shares is mutilated, lost, stolen or destroyed,
the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and
substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company
of such loss, theft or destruction and customary and reasonable indemnity, if requested. The applicants for a new certificate
or instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement
securities. If a replacement certificate or instrument evidencing any securities is requested due to a mutilation thereof, the
Company may require delivery of such mutilated certificate or instrument as a condition precedent to any issuance of a replacement.

 

5.5    Form
D; Blue Sky Filings. The Company agrees to timely file a Form D with respect to the Securities as required under Regulation
D promulgated under the Securities Act and to provide a copy thereof, promptly upon request of the Subscriber. The Company shall
take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for, or to qualify the
Securities for, sale to the Subscriber at the Closing under applicable securities or “Blue Sky” laws of the states
of the United States, and shall provide evidence of such actions promptly upon request of any Subscriber.

 

5.6    Equal
Treatment of Subscribers. No consideration (including any modification of any Transaction Document) shall be offered or paid
to any person to amend or consent to a waiver or modification of any provision of any of the Transaction Documents unless the
same consideration is also offered to all of the parties to the Transaction Documents. 

 

5.7    Indemnification. 

 

(a)      The
Company agrees to indemnify and hold harmless the Subscriber, its affiliates and their respective officers, directors, employees,
agents and controlling persons (collectively, the “Indemnified Parties”) from and against , any and all loss, liability,
damage or deficiency suffered or incurred by any Indemnified Party by reason of any misrepresentation or breach of warranty by
the Company or, after notice and a reasonable cure period, nonfulfillment of any covenant or agreement to be performed or complied
with by the Company under this Agreement or the Transaction Documents; and will promptly reimburse the Indemnified Parties for
all expenses (including reasonable fees and expenses of legal counsel) as incurred in connection with the investigation of, preparation
for or defense of any pending or threatened claim related to or arising in any manner out of any of the foregoing, or any action
or proceeding arising therefrom (collectively, “Proceedings”), whether or not such Indemnified Party is a formal party
to any such Proceeding.

 

    	13

    	 

    

 

(b)
     If for any reason (other than a final non-appealable judgment finding any Indemnified Party liable
for losses, claims, damages, liabilities or expenses for its gross negligence or willful misconduct) the foregoing indemnity is
unavailable to an Indemnified Party or insufficient to hold an Indemnified Party harmless, then the Company shall contribute to
the amount paid or payable by an Indemnified Party as a result of such loss, claim, damage, liability or expense in such proportion
as is appropriate to reflect not only the relative benefits received by the Company on the one hand and the Indemnified Party
on the other, but also the relative fault by the Company and the Indemnified Party, as well as any relevant equitable considerations.

 

5.10     Non-Public
Information. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction
Documents, the Company covenants and agrees that neither it, nor any other person acting on its behalf, will provide Subscriber
or its agents or counsel with any information that the Company believes constitutes material non-public information, unless prior
thereto Subscriber shall have executed a written agreement regarding the confidentiality and use of such information. The Company
understands and confirms that Subscriber shall be relying on the foregoing covenant in effecting transactions in securities of
the Company.

 

5.11     Use
of Proceeds. Except as set forth on Schedule 5.11 attached hereto, the Company shall use the net proceeds from the
sale of the Securities hereunder for working capital purposes and shall not use such proceeds for: (a) the satisfaction of any
portion of the Company’s debt (other than payment of trade payables in the ordinary course of the Company’s business
and prior practices), (b) the redemption of any Common Stock or Common Stock Equivalents (as defined in the Debenture and Warrant)
or (c) the settlement of any outstanding litigation.

or by a writing signed by the party to be charged. No waiver of any default with respect to any provision, condition or requirement

in any manner impair the exercise of any such right.

 

6.4     Successors
and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties hereto and to their respective heirs,
legal representatives, successors and assigns. The Company may not assign this Agreement or any rights or obligations hereunder

Right of Acceptance. Upon the execution and delivery of this Agreement by the Subscriber and the Company, this Agreement shall

6.7     Governing
Law. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents shall
be governed by and construed and enforced in accordance with the internal laws of the State of Minnesota, without regard to the
principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations, enforcement
and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a
party hereto or its respective affiliates, directors, officers, shareholders, employees or agents) shall be commenced exclusively
in the state and federal courts sitting in the City of Minneapolis. Each party hereby irrevocably submits to the exclusive jurisdiction
of the state and federal courts sitting in the City of Minneapolis for the adjudication of any dispute hereunder or in connection

Fees. Notwithstanding anything to the contrary in this Agreement, in order to discourage frivolous claims the parties agree

other party shall be entitled to recover from such claimant all of its/their reasonable legal costs and expenses relating to such
proceeding and/or incurred in preparation therefor.

any other provision of this Agreement, which shall remain in full force and effect. If any provision of this Agreement shall be
declared by a court of competent jurisdiction to be invalid, illegal or incapable of being enforced in whole or in part, such
provision shall be interpreted so as to remain enforceable to the maximum extent permissible consistent with applicable law and

constitute one and the same instrument. In the event that any signature is delivered by facsimile transmission or by e-mail delivery
of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or
on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature
page were an original thereof.

 

6.12   No
Third Party Beneficiaries. Nothing in this Agreement shall create or be deemed to create any rights in any person or entity
not a party to this Agreement.

Relief. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages,

RISK FACTORS

 

An investment
in the Securities involves a high degree of risk and is subject to many uncertainties. These risks and uncertainties may adversely
affect our business, operating results and financial condition. In such an event, the trading price for our common stock could
decline substantially, and you could lose all or part of your investment. In order to attain an appreciation for these risks and
uncertainties, you should read these risk factors in their entirety and consider all of the information and advisements contained
in the Transaction Documents, including the following risk factors and uncertainties.

 

    	24

    	 

    

 

RISKS
RELATED TO OUR BUSINESS

 

We have
a limited operating history with significant losses and expect losses to continue for the foreseeable future.

 

We have yet
to establish any history of profitable operations. We have incurred annual operating losses of approximately $4,321,000 and $4,768,000,
respectively, during the past two years of operations and an approximate $762,545 operating loss for the three-month period ended
March 31, 2013. As a result, at March 31, 2013 we had an accumulated deficit of approximately $41,200,000. We have incurred net
losses from continuing operations of approximately $9,093,000 and $4,762,000 for the fiscal years ended December 31, 2012 and
2011, respectively, and a net loss from continuing operations of approximately $2,600,000 for the three-month period ended March
31, 2013. Our revenues have not been sufficient to sustain our operations and we expect that they will be insufficient to sustain
our operations for the foreseeable future. Our failure to generate meaningful revenues and ultimately profits from the WavSTAT
System and applications of our technology could and will likely require that we raise additional capital which may not be available
or available on acceptable terms. This could ultimately reduce or suspend our operations and ultimately cause us to go out of
business. Our profitability will require the successful commercialization of our imaging systems and no assurances can be given
when this will occur or if we will ever be profitable.

 

We will
require additional financing to sustain our operations and without it, we may not be able to continue operations. The Company
needs additional capital beyond this offering to sustain any operations for longer than 6 months; if unable to raise such capital,
the Company may be forced to cease operations and any investment may be entirely lost.

 

At March 31,
2013, we had a working capital deficit of approximately $5,600,000. We had an operating cash flow deficit of approximately $507,000
for the three-month period ended March 31, 2013, $2,887,000 for the fiscal year ended December 31, 2012 and an operating cash
flow deficit of approximately $3,263,000 in fiscal 2011. We may not have sufficient financial resources to fund our operations
and will likely require additional funds to continue our operations.

 

We may
face intense competition from companies that have greater financial, personnel and research and development resources.

 

Competitive
forces may impact our projected growth and ability to generate revenues and profits, which would have a negative impact on our
business and the price of our common stock. Our competitors may be developing products that compete with the WavSTAT Systems.
Our commercial opportunities would then be reduced or eliminated should our competitors develop and market products for any of
the diseases that we target that are more effective or are less expensive than the products or product candidates we are developing.

 

Even if we
obtain FDA and other regulatory approvals necessary for commercialization, our products may not compete effectively with other
successful products. Researchers are continually learning more about diseases, which may lead to new technologies and tools for
analysis.

 

    	25

    	 

    

 

Our competitors
include fully integrated medical device companies, universities and public and private research institutions. Many of the organizations
competing with us may have substantially greater capital resources, larger research and development staffs and facilities, greater
experience in product development and in obtaining regulatory approvals, and greater marketing capabilities than we do.

 

The market
for medical devices is intensely competitive. Many of our potential competitors have longer operating histories, greater name
recognition, more employees, and significantly greater financial, technical, marketing, public relations, and distribution resources
than we have. This intense competitive environment may require us to make changes in our products, pricing, licensing, services
or marketing to develop, maintain and extend our current technology. Price concessions or the emergence of other pricing or distribution
strategies of competitors may diminish our revenues, adversely impact our margins or lead to a reduction in our market share,
any of which may harm our business.

 

Our WavSTAT
System technology may become obsolete.

 

Our WavSTAT
System products may be made unmarketable by new scientific or technological developments where new treatment modalities are introduced
that are more efficacious or more economical. Any one of our competitors could develop a more effective product which would render
our technology obsolete.

 

Our inability
to attract and retain qualified personnel could impede our ability to generate revenues and profits and to otherwise implement
our business plan and growth strategies, which would have a negative impact on our business and could adversely affect the price
of our common stock.  

 

We currently
have a staff of six full time employees, consisting of, among others, our Chief Executive Officer, Director of Operations, Director
of Engineering, Director of Business Development for Europe and an Associate Engineer as well as administrative and regulatory
employees and other personnel retained on a contract basis. We will be required over the longer-term to hire highly skilled managerial,
scientific and administrative personnel to fully implement our business plan and growth strategies. We cannot assure you that
we will be able to engage the services of such qualified personnel at competitive prices or at all, particularly given the risks
of employment attributable to our limited financial resources and lack of an established track record.

 

Our planned
growth will place strains on our management team and other company resources to both implement more sophisticated managerial,
operational and financial systems, procedures and controls and to train and manage the personnel necessary to perform those functions.
Our inability to manage our growth could impede our ability to generate revenues and profits and to otherwise implement our business
plan and growth strategies, which would have a negative impact on our business and the market value of the Company.

 

    	26

    	 

    

 

We will need
to significantly expand our operations to implement our longer-term business plan and growth strategies. We will also be required
to manage multiple relationships with various strategic partners, technology licensors, customers, manufacturers and suppliers,
consultants and other third parties. This expansion and these expanded relationships will require us to significantly improve
or replace our existing managerial, operational and financial systems, procedures and controls; to improve the coordination between
our various corporate functions; and to manage, train, motivate and maintain a growing employee base. The time and costs to effectuate
these steps may place a significant strain on our management personnel, systems and resources, particularly given the limited
amount of financial resources and skilled employees that may be available at the time. We cannot assure you that we will institute,
in a timely manner or at all, the improvements to our managerial, operational and financial systems, procedures and controls necessary
to support our anticipated increased levels of operations and to coordinate our various corporate functions, or that we will be
able to properly manage, train, motivate and retain the anticipated increased number of employees.

 

We may
have difficulty in developing and retaining an effective sales force or in obtaining effective distribution partners and may not
be able to achieve sufficient revenues to effect our business plan.

 

The market
for skilled sales and marketing personnel is highly competitive and specialized. If we are unable to hire and retain skilled and
knowledgeable sales people it may negatively impact our ability to introduce our products or generate revenue sufficient to affect
our future business plans. In addition, our inability to develop business relationships with key technical distributors may also
negatively impact our ability to successfully market our products.

 

We may
have difficulty in attracting and retaining management and outside independent members to our Board of Directors as a result of
their concerns relating to their increased personal exposure to lawsuits and shareholder claims by virtue of holding these positions
in a publicly held company.

 

The directors
and management of publicly traded corporations are increasingly concerned with the extent of their personal exposure to lawsuits
and shareholder claims, as well as governmental and creditor claims which may be made against them, particularly in view of recent
changes in securities laws imposing additional duties, obligations and liabilities on management and directors. Due to these perceived
risks, directors and management are also becoming increasingly concerned with the availability of directors and officers liability
insurance to pay on a timely basis the costs incurred in defending such claims. We currently carry directors and officers liability
insurance, but such insurance is expensive and can be difficult to obtain. If we are unable to obtain directors and officers liability
insurance at affordable rates or at all in the future, it may become increasingly more difficult to attract and retain qualified
outside directors to serve on our board of directors. The fees of directors are also rising in response to their increased duties,
obligations and liabilities as well as increased exposure to such risks. As a company with a limited operating history and limited
resources, we will have a more difficult time attracting and retaining management and outside independent directors than a more
established company due to these enhanced duties, obligations and liabilities.  

 

    	27

    	 

    

 

If we
fail to comply with extensive regulations enforced by domestic and foreign regulatory authorities, the commercialization of our
products could be prevented or delayed.

 

Our WavSTAT
Systems are subject to extensive government regulations related to development, testing, manufacturing and commercialization in
the United States and other countries. The determination of when and whether a product is ready for large scale purchase and potential
use will be made by the government through consultation with a number of governmental agencies, including the FDA, the National
Institutes of Health, and the Centers for Disease Control and Prevention. Some of our product candidates are in the clinical stages
of development and have not received required regulatory approval from the FDA for applications we hope to commercially market.
The process of obtaining and complying with the FDA and other governmental regulatory approvals and regulations is costly, time
consuming, uncertain and subject to unanticipated delays. Despite the time and expense incurred, regulatory approval is never
guaranteed. We also are subject to the following risks and obligations, among others:

 

	 	·	The
    FDA may refuse to approve an application if they believe that applicable regulatory criteria are not satisfied;

 

	 	·	The
    FDA may require additional testing for safety and effectiveness;

 

	 	·	The
    FDA may interpret data from pre-clinical testing and clinical trials in different ways than us;

 

	 	·	If
    regulatory approval of a product is granted, the approval may be limited to specific indications or limited with respect to
    its distribution; and

 

	 	·	The
    FDA may change their approval policies and/or adopt new regulations.

 

Failure to
comply with these or other regulatory requirements of the FDA may subject us to administrative or judicially imposed sanctions,
including:

 

	 	·	Warning
    letters;

  

    	28

    	 

    

  

	 	·	Civil
    penalties;

 

	 	·	Criminal
    penalties;

 

	 	·	Injunctions;

 

	 	·	Product
    seizure or detention;

 

	 	·	Product
    recalls; and

 

	 	·	Total
    or partial suspension of production.

 

Delays
in successfully completing our clinical and European evaluation trials could jeopardize our ability to obtain regulatory approval
or market our WavSTAT System candidates on a timely basis.

 

Our business
prospects will depend on our ability to complete clinical trials, obtain satisfactory results, obtain required regulatory approvals
and successfully commercialize our WavSTAT System product candidates. Completion of our clinical trials, announcement of results
of the trials and our ability to obtain regulatory approvals could be delayed for a variety of reasons, including:

 

	 	·	Unsatisfactory
    results of any clinical trial;

 

	 	·	The
    failure of principal third-party investigators to perform clinical trials on our anticipated schedules; and

 

	 	·	Different
    interpretations of pre-clinical and clinical data, which could initially lead to inconclusive results.

 

    	29

    	 

    

 

Our development
costs will increase if we have material delays in any clinical trial or if we need to perform more or larger clinical trials than
planned.  

 

If clinical
or evaluation trial delays are significant, or if any of our WavSTAT System product candidates do not prove to be safe or effective
or do not receive required regulatory approvals, our financial results and the commercial prospects for our product candidates
will be harmed. Furthermore, our inability to complete our clinical trials in a timely manner could jeopardize our ability to
obtain regulatory approval.

 

The independent
clinical investigators that we rely upon to conduct our clinical trials may not be diligent, careful or timely, and may make mistakes,
in the conduct of our clinical trials.

 

We depend on
independent clinical investigators to conduct our clinical trials. The investigators are not our employees, and we cannot control
the amount or timing of resources that they devote to our product development programs. If independent investigators fail to devote
sufficient time and resources to our product development programs, or if their performance is substandard, it may delay FDA approval
of our products. These independent investigators may also have relationships with other commercial entities, some of which may
compete with us. If these independent investigators assist our competitors at our expense, it could harm our competitive position.

 

Our product
development efforts may not yield marketable products due to results of studies or trials, failure to achieve regulatory approvals
or market acceptance, proprietary rights of others or manufacturing issues.

 

Our success
depends on our ability to successfully develop and obtain regulatory approval to market new products. We expect that a significant
portion of the research that we will conduct will involve new and unproven technologies. Development of a product requires substantial
technical, financial and human resources even if the product is not successfully completed.

 

Potential products
may appear to be promising at various stages of development yet fail to reach the market for a number of reasons, including the:

 

	 	·	Lack
    of adequate quality or sufficient prevention benefit, or unacceptable safety during pre-clinical studies or clinical trials;

 

	 	·	Failure
    to receive necessary regulatory approvals;

 

	 	·	Existence
    of proprietary rights of third parties; and/or

 

    	30

    	 

    

 

	 	·	Inability
    to develop manufacturing methods that are efficient, cost-effective and capable of meeting stringent regulatory standards.

 

Our inability
to protect our intellectual property rights could negatively impact our projected growth and ability to generate revenues and
profits, which would have a negative impact on our business and the value of your investment.

 

We rely on
a combination of patent, patent pending, copyright, trademark and trade secret laws, proprietary rights agreements and non-disclosure
agreements to protect our intellectual properties. These measures may not prove to be effective in protecting our intellectual
properties.

 

In the case
of patents, our existing patents may be invalidated, any patents that we currently or prospectively apply may not be granted,
or any of these patents may not ultimately provide significant commercial benefits. Further, competing companies may circumvent
any patents that we may hold by developing products which closely emulate but do not infringe our patents. While we currently
have and intend to seek patent protection for our products in selected foreign countries, those patents may not receive the same
degree of protection as they would in the United States. We may not be able to successfully defend our patents and proprietary
rights in any action we may file for patent infringement. Similarly, we may be required to defend litigation involving the patents
or proprietary rights of others, or we may be able to obtain licenses for these rights. Legal and accounting costs relating to
prosecuting or defending patent infringement litigation may be substantial.

 

The WavSTAT
System is protected by 34 issued patents, in the United States and approximately 25 foreign patents, which we own, and one additional
patent for which we own the exclusive license. We also rely on proprietary designs, technologies, processes and know-how not eligible
for patent protection. Our competitors may independently develop the same or superior designs, technologies, processes and know-how.
 

 

While we have
and will continue to enter into proprietary rights agreements with our employees and third parties giving us proprietary rights
to certain technology developed by those employees or parties while engaged by the Company, courts of competent jurisdiction may
not enforce those agreements.

 

The patents
we own comprise a large portion of our assets, which could limit our financial viability.

 

Our patents
comprise approximately 63% of our assets at March 31, 2013. If our existing patents are invalidated or if they fail to provide
significant commercial benefits, it will severely hurt our financial condition, as a significant percentage of our assets would
lose their value. Further, since our patents are amortized over the course of their term until they expire, our assets comprised
of patents will continually be written down to zero.

 

    	31

    	 

    

 

We have
not complied with all reporting and other corporate governance compliance obligations and may continue to be non-compliant for
the foreseeable future.

 

Compliance
with publicly-traded company regulations adversely impacts our resources. As a publicly-traded company, we are subject to rules
and regulations that increase our legal and financial compliance costs, make some activities more time-consuming and costly, and
divert our management's attention away from the operation of our business. We are obligated to file with the U.S. Securities and
Exchange Commission, or the SEC, annual and quarterly information and other reports that are specified in the Securities Exchange
Act of 1934, or the Exchange Act, and are also subject to other reporting and corporate governance requirements, including requirements
of the Sarbanes-Oxley Act of 2002, and the rules and regulations promulgated thereunder, which impose significant compliance and
reporting obligations upon us.  We have not been successful in complying with these obligations, including without limitation,
filing a required Quarterly Report on Form 10-Q for the three-month period ended June 30, 2013. This failure to comply with the
reporting and corporate governance requirements, as well as any future compliance failures, could lead to fines imposed on us,
deregistration under the Exchange Act and, in the most egregious cases, criminal sanctions could be imposed. Compliance with Exchange
Act and other reporting and corporate governance obligations is time consuming and expensive, and the Company may continue to
operate without complying with such requirements.

 

Our products
may be subject to recall or product liability claims.

 

Our WavSTAT
System products may be used in connection with medical procedures in which it is important that those products function with precision
and accuracy. If our products do not function as designed, or are designed improperly, we may be forced by regulatory agencies
to withdraw such products from the market. In addition, if medical personnel or their patients suffer injury as a result of any
failure of our products to function as designed, or due to an inappropriate design, we may be subject to lawsuits seeking significant
compensatory and punitive damages. Any product recall or lawsuit seeking significant monetary damages may have a material effect
on our business and financial condition.

 

We are
heavily reliant on a single distributor to market and sell our WavSTAT System.

 

PENTAX is the
sole distributor of our WavSTAT System. We have limited control over PENTAX’s sales and marketing efforts for our primary
product. We do not presently have any other distributors for our WavSTAT System, and are solely dependent on the distribution
efforts of PENTAX. If PENTAX were to scale back or terminate its distribution relationship with us, we may be unable to find a
distributor with the scale and resources of PENTAX, if at all. Since the WavSTAT System is our sole source of revenues and projected
revenue growth, a delay or failure by PENTAX to successfully market the product will decrease our future revenues and competitive
advantage.

 

    	32

    	 

    

 

If We Are Required for any
Reason to Repay Our Outstanding Convertible Debentures, We Would Be Required to Deplete Our Working Capital, if Available, or
Raise Additional Funds. Our Failure to Repay the Convertible Debentures, if Required, could Result in Legal Action Against Us,
which could Require the Sale of Substantial Assets.

 

Between January 27, 2012 and June
14, 2013, we have entered into subscription agreements for the sale of an aggregate of $4,261,053 principal amount of convertible
debentures ($1,910,526 outstanding balance as of the date hereof). The convertible debentures are due and payable, with interest,
six months from the date of issuance, unless sooner converted into shares of our common stock. In addition, any event of default
such as our failure to repay the principal or interest when due, our failure to issue shares of common stock upon conversion by
the holder, breach of any covenant, representation or warranty in the respective subscription agreement or related convertible
debenture, a change of control or other fundamental transaction involving our company, the assignment or appointment of a receiver
to control a substantial part of our property or business, the filing of a money judgment, writ or similar process against our
company in excess of $100,000, the commencement of a bankruptcy, insolvency, reorganization or liquidation proceeding against
our company and the delisting of our common stock could require the early repayment of the convertible debentures, including a
default interest rate of 18% on the outstanding principal balance of the notes if the default is not cured with the specified
grace period. We anticipate that the full amount of the convertible debentures will be converted into shares of our common stock,
in accordance with the terms of the convertible debentures. If we are required to repay the convertible debentures, we would be
required to use our limited working capital and raise additional funds. If we were unable to repay the debentures when required,
the debenture holders could commence legal action against us to recover the amounts due. Any such action would require us to curtail
or cease operations. 

 

We are Currently in Default
under the Convertible Debentures issued between [August 28, 2012 and February 28, 2013] and the Investors could, if they were
to successfully enforce their rights under the Convertible Debentures through a lawsuit, levy on our assets and have them sold
to satisfy our obligations on the Convertible Debentures.

 

Pursuant to the terms of the convertible
debentures issued between August 28, 2012 and February 28, 2013, each of the debentures has matured and an event of default
has occurred under each of the respective debentures. We currently owe the investors $1,478,952 in face amount of convertible
debentures, plus applicable interest and applicable default payments. Holders of these convertible debentures could, if they choose
to sue on these convertible debentures, and if they were to successfully obtain a judgment on the Company, levy on our assets
and have those assets sold to satisfy the amounts we owe them. 

 

The Sheldon Miller Loan Transaction
Will Result in a Default under the Convertible Debentures Issued Between August 28, 2012 and June 14, 2013 and the Investors Could
Cause Acceleration of the Outstanding Principal Amount of Such Debentures, Plus Accrued but Unpaid Interest, Liquidated Damages
and Other Amounts Owing to Such Investors.

 

    	33

    	 

    

 

In addition
to the payment default described above, the loan agreement, issuance of promissory note and issuance of shares to Sheldon Miller,
as described in Schedule 2.14, will cause an event of default under the convertible debentures issued between August 28,
2012 and June 14, 2013. An event of default allows the holders of these convertible debentures to accelerate the outstanding principal
amount of such debentures, plus accrued but unpaid interest, liquidated damages and other amounts owing to such investors. If
such acceleration occurs, Holders of these convertible debentures could, if they choose to sue on these convertible debentures,
and if they were to successfully obtain a judgment on the Company, levy on our assets and have those assets sold to satisfy the
amounts we owe them.

 

RISKS
RELATED TO OUR CAPITAL STOCK

 

The application
of the “penny stock” rules could adversely affect the market price of our Common Stock and increase your transaction
costs to sell your stock.

 

As long as
the trading price of our Common Stock is below $5 per share, the open-market trading of our Common Stock will be subject to the
“penny stock” rules. The “penny stock” rules impose additional sales practice requirements on broker-dealers
who sell securities to persons other than established customers and accredited investors (generally those with assets in excess
of $1,000,000 or annual income exceeding $200,000 or $300,000 together with their spouse). For transactions covered by these rules,
the broker-dealer must make a special suitability determination for the purchase of securities and have received the purchaser’s
written consent to the transaction before the purchase. Additionally, for any transaction involving a penny stock, unless exempt,
the broker-dealer must deliver, before the transaction, a disclosure schedule prescribed by the SEC relating to the penny stock
market. The broker-dealer also must disclose the commissions payable to both the broker-dealer and the registered representative
and current quotations for the securities. Finally, monthly statements must be sent disclosing recent price information on the
limited market in penny stocks. These additional burdens imposed on broker-dealers may restrict the ability or decrease the willingness
of broker-dealers to sell our common stock, and may result in decreased liquidity for our common stock and increased transaction
costs for sales and purchases of our common stock as compared to other securities.

 

Our common
stock is thinly traded, so investors may be unable to sell at or near ask prices or at all.

 

Our common
stock has historically been sporadically or “thinly-traded”, meaning that the number of persons interested in purchasing
our Common Stock at or near ask prices at any given time may be relatively small or non-existent. As of March 31, 2013, our average
trading volume per day for the past three months was approximately 72,000 shares a day with a high of 841,800 shares traded and
a low of 0 shares traded per day. This situation is attributable to a number of factors, including the fact that we are a small
company which is relatively unknown to stock analysts, stock brokers, institutional investors and others in the investment community
that generate or influence sales volume, and that even if we came to the attention of such persons, they tend to be risk-averse
and would be reluctant to follow an unproven company such as ours or purchase or recommend the purchase of our shares until such
time as we became more seasoned and viable. As a consequence, there may be periods of several days or more when trading activity
in our shares is minimal or non-existent, as compared to a seasoned issuer which has a large and steady volume of trading activity
that will generally support continuous sales without an adverse effect on share price. A broader or more active public trading
market for our common stock may not develop or be sustained, and current trading levels may not be sustained.

The market
price for our common stock is particularly volatile, given our status as a relatively unknown company with a small and thinly-traded
public float, limited operating history and lack of revenues which could lead to wide fluctuations in our share price.

 

The market
for our Common Stock is characterized by significant price volatility when compared to seasoned issuers, and we expect that our
share price will continue to be more volatile than a seasoned issuer for the foreseeable future. In fact, during the 90-day period
ended March 31, 2013, the high and low closing prices of a share of our Common Stock were $0.08 and $0.05, respectively. The volatility
in our share price is attributable to a number of factors. First, as noted above, our stock is sporadically and/or thinly-traded.
As a consequence of this lack of liquidity, the trading of relatively small quantities of shares by our shareholders may disproportionately
influence the price of those shares in either direction. The price for our shares could, for example, decline precipitously in
the event that a large number of our shares are sold on the market without commensurate demand, as compared to a seasoned issuer
which could better absorb those sales without adverse impact on its share price. Secondly, we are a speculative or “risky”
investment due to our limited operating history and lack of revenues or profits to date and uncertainty of future market acceptance
for our potential products. As a consequence of this enhanced risk, more risk-adverse investors may, under the fear of losing
all or most of their investment in the event of negative news or lack of progress, be more inclined to sell their shares on the
market more quickly and at greater discounts than would be the case with the stock of a seasoned issuer. The following factors
may add to the volatility in the price of our common stock: actual or anticipated variations in our quarterly or annual operating
results; acceptance of our proprietary technology; government regulations, announcements of significant acquisitions, strategic
partnerships or joint ventures; our capital commitments; and additions or departures of our key personnel. Many of these factors
are beyond our control and may decrease the market price of our common stock, regardless of our operating performance. We cannot
make any predictions or projections as to what the prevailing market price for our common stock will be at any time, including
as to whether our common stock will sustain its current market prices, or as to what effect that the sale of shares or the availability
of common stock for sale at any time will have on the prevailing market price.

The market
for penny stocks such as ours has been subject to fraud and abuse and may cause our stock price to be more volatile.

 

Shareholders
should be aware that, according to SEC Release No. 34-29093, the market for penny stocks has suffered in recent years from patterns
of fraud and abuse. Such patterns include (1) control of the market for the security by one or a few broker-dealers that are often
related to the promoter or issuer; (2) manipulation of prices through prearranged matching of purchases and sales and false and
misleading press releases; (3) boiler room practices involving high-pressure sales tactics and unrealistic price projections by
inexperienced sales persons; (4) excessive and undisclosed bid-ask differential and markups by selling broker-dealers; and (5)
the wholesale dumping of the same securities by promoters and broker-dealers after prices have been manipulated to a desired level,
along with the resulting inevitable collapse of those prices and consequent investor losses. Our management is aware of the abuses
that have occurred historically in the penny stock market. The occurrence of these patterns or practices could increase the volatility
of our share price. In addition, potential dilutive effects of future sales of shares of common stock by shareholders and by the
Company, including in this offering, could have an adverse effect on the market price of our shares.

 

Volatility
in our common stock price may subject us to securities litigation.

 

The market
for our common stock is characterized by significant price volatility when compared to seasoned issuers, and we expect that our
share price will continue to be more volatile than a seasoned issuer for the indefinite future. In the past, plaintiffs have sometimes
initiated securities class action litigation against a company following periods of volatility in the market price of its securities.
We may in the future be the target of similar litigation. Securities litigation could result in substantial costs and liabilities
and could divert management’s attention and resources.

 

A large
number of shares of common stock are issuable upon exercise of outstanding options and the exercise of these securities could
result in the substantial dilution of the investment of other shareholders in terms of percentage ownership in the Company as
well as the book value of the common stock.

 

As of March
31, 2013, there are outstanding common stock purchase options entitling the holders to purchase 19,491,667 shares of common stock
at a weighted average exercise price of $0.18 per share (with approximately 10,590,000 of these shares exercisable within 60 days
of March 31, 2013). The exercise price for all of the options may be less than the cost to acquire our common stock. In addition,
the holders of the common stock purchase options may sell common stock in tandem with their exercise of those options to finance
that exercise, or may resell the shares purchased in order to cover any income tax liabilities that may arise from their exercise
of the options, which could substantially depress the prevailing market price of our common stock.

 

Our issuance
of additional common stock, or options to purchase our common stock, would dilute the proportionate ownership and voting rights
of shareholders.

 

We are entitled
under our articles of incorporation to issue up to 325,000,000 shares of capital stock which includes 275,000,000 shares of common
stock, 3,585,000 shares of preferred stock and 46,415,000 undesignated shares. Our undesignated shares may be designated as in
a senior position to our common stock. After taking into consideration our outstanding common stock at March 31, 2013, we will
be entitled to issue up to 40,242,494 additional shares of stock (325,000,000 authorized less 159,253,139 common shares outstanding,
3,585,000 shares for issuance upon conversion of Preferred Stock, 21,545,000 shares reserved for issuance of stock options, 2,000,000
shares reserved for issuance of restricted stock grants to consultants, 70,210,121 shares reserved for issuance of Common Stock
purchase warrants, 27,796,733 shares for issuance of convertible debentures and 367,513 shares of Common Stock issued for payment
of cumulative preferred dividends). Our board of directors may generally issue stock, or options or warrants to purchase that
stock, without further approval by our shareholders based upon such factors as our board of directors may deem relevant at that
time. It is likely that we will be required to issue a large amount of additional securities to raise capital to further our development.
It is also likely that we will be required to issue a large amount of additional securities to directors, officers, employees
and consultants as compensatory grants in connection with their services, both in the form of stand-alone grants or under our
stock plans. We may not be able to issue additional shares of Common Stock, or options or warrants to purchase those shares, under
circumstances we may deem appropriate at the time.

The limitation
of monetary liability of our directors, officers and employees under our articles of incorporation and the indemnification rights
of our directors, officers, consultants and employees may result in substantial expenditures by us and may discourage lawsuits
against our directors, officers, consultants and employees.

 

Our amended
and restated articles of incorporation, as amended, contain provisions which eliminate the liability of our directors and officers
for monetary damages to the Company and shareholders. Our bylaws also require us to indemnify our officers and directors. We may
also have contractual indemnification obligations under our agreements with our directors, officers, consultants and employees.
The foregoing indemnification obligations could result in the Company incurring substantial expenditures to cover the cost of
settlement or damage awards against directors, officers, consultants and employees, which we may be unable to recoup. These provisions
and resultant costs may also discourage us from bringing a lawsuit against directors, officers, consultants and employees for
breaches of their fiduciary duties, and may similarly discourage the filing of derivative litigation by our shareholders against
our directors, officers, consultants and employees even though such actions, if successful, might otherwise benefit the Company
and shareholders.

 

Anti-takeover
provisions may impede the acquisition of the Company.

 

Certain provisions
of the Minnesota Business Corporation Act and other Minnesota laws have anti-takeover effects and may inhibit a non-negotiated
merger or other business combination. These provisions are intended to encourage any person interested in acquiring us to negotiate
with, and to obtain the approval of, our board of directors in connection with such a transaction. However, certain of these provisions
may discourage a future acquisition of the Company, including an acquisition in which the shareholders might otherwise receive
a premium for their shares. As a result, shareholders who might desire to participate in such a transaction may not have the opportunity
to do so.

RISKS
RELATED TO THIS OFFERING

 

There
will be restrictions on resale of the securities and the shares and there is no assurance of the registration of the securities.

 

None of the
Securities or Shares may be sold unless, at the time of such intended sale, there is a current registration statement covering
the resale of the Securities and Shares or there exists an exemption from registration under the Securities Act, and such Securities
and Shares have been registered, qualified, or deemed to be exempt under applicable securities or “blue sky” laws
in the state of residence of the seller or in the state where sales are being effected. If no registration statement is filed
and declared effective covering the resale of any of the Securities or Shares sold pursuant to this Agreement, investors will
be precluded from disposing of such securities unless such securities may become eligible to be disposed of under the exemptions
provided by Rule 144 under the Securities Act without restriction. If the securities sold pursuant to this Offering are not registered
for resale under the Securities Act, or exempt therefrom, and registered or qualified under applicable securities or “blue
sky” laws, or deemed exempt therefrom, the value of the such securities will be greatly reduced.

 

We have
significant discretion over the use of certain of the net proceeds.

 

Assuming that
all of the Securities offered by this Agreement are sold, the proceeds to us from the sale of the Securities will be approximately
$920,000 if the Maximum Offering is sold. A significant portion of the net proceeds of this Offering will be applied to working
capital and other general corporate purposes. Accordingly, our management will have broad discretion as to the application of
such proceeds. There can be no assurance that management’s use of proceeds generated through this Offering will prove optimal
or translate into revenue or profitability for the Company. Investors are urged to consult with their attorneys, accountants and
personal investment advisors prior to making any decision to invest in the Company.

 

The offering
price for the securities has been arbitrarily determined by us.

 

The offering
price of the Securities was arbitrarily determined by us. The price of the Securities does not necessarily bear any relationship
to established valuation criteria such as earnings, book value or assets. Rather, the price of the Securities may be derived as
a result of our negotiations with the investors based upon various factors including prevailing market conditions, our future
prospects and our capital structure. These prices do not necessarily accurately reflect the actual value of the Securities or
the price that may be realized upon disposition of the Securities or the Shares.

 

An investment
in our securities is speculative and there can be no assurance of any return on any such investment.

 

An investment
in the Securities is speculative and there is no assurance that investors will obtain any return on their investment. Investors
will be subject to substantial risks involved in an investment in the Company, including the risk of losing their entire investment.

Your
ownership interest is subject to dilution. 

 

If you purchase
Securities in this Offering, you will experience immediate dilution in the value of your Shares received upon conversion or exercise.
In addition, each investor’s proportionate ownership interest may be diluted when we issue additional shares of our common
stock. We may raise additional capital in the future through additional sales of shares of our common stock, and your percentage
interest in our common stock would be diluted if you do not participate in such additional sales.
