AND CONFIDENTIAL INFORMATION. The Executive has had access to and has acquired, will have access to and will acquire, and has
assisted in and may assist in developing confidential and proprietary information relating to the business and operations of the
Employer and its affiliates, including but not limited to information with respect to present and prospective business plans, financing
arrangements, marketing plans, customer and supplier lists, contracts and proposals.

 

The Executive acknowledges
that such information has been and will continue to be of central importance to the business of the Employer and its affiliates
and that its disclosure or use by others could cause substantial loss to the Employer and its affiliates.  The Executive
and the Employer also recognize that an important part of the Executive’s duties have been, and will continue to be, to develop
goodwill for the Employer and its affiliates through his personal contact with vendors, customers, subcontractors, and others sharing
business relationships with the Employer and its affiliates, and that there is a danger that this goodwill, a proprietary asset
of the Employer and its affiliates, may follow the Executive if and when his employment relationship with the Employer ends.

The Executive accordingly
agrees that without Employer’s written consent, during the Employment Period, the Executive will not, either individually
or as owner, partner, agent, employee, consultant, or in any other capacity, engage in any activity competitive with the Employer
or any of its affiliates and will not on his own behalf, or on behalf of any third party, directly or indirectly hire, discuss
employment with, or recommend to any third party the employment of any employee of the Employer, or any of its affiliates, who
was employed by the Employer or an affiliate on the Effective Date, without regard to whether that employee’s employment
with the Employer has subsequently ceased for any reason.

 

Nothing in this Article
II shall be construed to prevent the Executive from owning, as an investment, not more than Ten percent (10%) of a class of
equity securities issued by any issuer and publicly traded and registered under Section 12 of the Securities Exchange Act of 1934.

 

2.2           NON-DISCLOSURE.  At
all times after the Effective Date, the Executive will keep confidential any confidential or proprietary information of the Employer
and its affiliates which is now known to him or which hereafter may become known to him as a result of his employment or association
with the Employer and shall not at any time directly or indirectly disclose any such information to any person, firm or employer,
or use the same in any way other than in connection with the business of the Employer and its affiliates, or pursuant to any duly

ARTICLE III. 

REPRESENTATIONS AND WARRANTIES

 

3.1          Representations
and Warranties of the Company. Except as set forth in the SEC Reports or the Disclosure Schedules, which Disclosure
Schedules shall be deemed a part hereof and shall qualify any representation or otherwise made herein to the extent of the disclosure
contained in the corresponding section of the Disclosure Schedules, the Company hereby makes the following representations and
warranties to each Purchaser:

 

(a)        Subsidiaries.
All of the direct and indirect subsidiaries of the Company are set forth on Schedule 3.1(a). The Company owns, directly
or indirectly, all of the capital stock or other equity interests of each Subsidiary free and clear of any Liens, and all of the
issued and outstanding shares of capital stock of each Subsidiary are validly issued and are fully paid, non-assessable and free
of preemptive and similar rights to subscribe for or purchase securities. If the Company has no subsidiaries, all other references
to the Subsidiaries or any of them in the Transaction Documents shall be disregarded.

 

(b)        Organization
and Qualification. The Company and each of the Subsidiaries is an entity duly incorporated or otherwise organized, validly
existing and in good standing under the laws of the jurisdiction of its incorporation or organization, with the requisite power
and authority to own and use its properties and assets and to carry on its business as currently conducted. Neither the Company
nor any Subsidiary is in violation nor default of any of the provisions of its respective certificate or articles of incorporation,
bylaws or other organizational or charter documents. Each of the Company and the Subsidiaries is duly qualified to conduct business
and is in good standing as a foreign corporation or other entity 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, could not have or reasonably be expected to result in: (i) a material adverse effect on the legality, validity
or enforceability of any Transaction Document, (ii) a material adverse effect on the results of operations, assets, business, prospects
or condition (financial or otherwise) of the Company and the Subsidiaries, taken as a whole, or (iii) a material adverse effect
on the Company’s ability to perform in any material respect on a timely basis its obligations under any Transaction Document
(any of (i), (ii) or (iii), a “Material Adverse Effect”) and no Proceeding has been instituted in any such jurisdiction
revoking, limiting or curtailing or seeking to revoke, limit or curtail such power and authority or qualification.

(c)        Authorization;
Enforcement. The Company has the requisite corporate power and authority to enter into and to consummate the transactions contemplated
by this Agreement and each of the other Transaction Documents and otherwise to carry out its obligations hereunder and thereunder.
The execution and delivery of this Agreement and each of the other Transaction Documents by the Company and the consummation by
it of the transactions contemplated hereby and thereby have been duly authorized by all necessary action on the part of the Company
and no further action is required by the Company, the Board of Directors or the Company’s stockholders in connection herewith
or therewith other than in connection with the Required Approvals. This Agreement and each other Transaction Document to which
it is a party has been (or upon delivery will have been) duly executed by the Company and, when delivered in accordance with the
terms hereof and thereof, will constitute the valid and binding obligation of the Company enforceable against the Company in accordance
with its terms, except: (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium
and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating
to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification
and contribution provisions may be limited by applicable law.

 

(d)        No
Conflicts. The execution, delivery and performance by the Company of this Agreement and the other Transaction Documents, the
issuance and sale of the Securities and the consummation by it of the transactions contemplated hereby and thereby to which it
is a party do not and will not: (i) conflict with or violate any provision of the Company’s or any Subsidiary’s certificate
or articles of incorporation, bylaws or other organizational or charter documents, (ii) conflict with, or constitute a default
(or an event that with notice or lapse of time or both would become a default) under, result in the creation of any Lien upon any

or cancellation (with or without notice, lapse of time or both) of, any agreement, credit facility, debt or other instrument (evidencing
a Company or Subsidiary debt or otherwise) or other understanding to which the Company or any Subsidiary is a party or by which
any property or asset of the Company or any Subsidiary is bound or affected, or (iii) subject to the Required Approvals, conflict

or governmental authority to which the Company or a Subsidiary is subject (including federal and state securities laws and regulations),

and (iii), such as could not have or reasonably be expected to result in a Material Adverse Effect.

(e)        Filings,
Consents and Approvals. The Company is not required to obtain any consent, waiver, authorization or order of, give any notice
to, or make any filing or registration with, any court or other federal, state, local or other governmental authority or other
Person in connection with the execution, delivery and performance by the Company of the Transaction Documents, other than: (i)
the filings required pursuant to Section 4.6 of this Agreement, (ii) the filing with the Commission pursuant to the Registration
Rights Agreement, (iii) the notice and/or application(s) to each applicable Trading Market for the issuance and sale of the Preferred
Stock and Warrant Shares and the listing of the Underlying Shares for trading thereon in the time and manner required thereby and
(iv) the filing of Form D with the Commission and such filings as are required to be made under applicable state securities laws
(collectively, the “Required Approvals”).

 

(f)        Issuance
of the Securities. 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 nonassessable, free and clear of all Liens imposed by the Company. The
Underlying Shares, when issued in accordance with the terms of the Transaction Documents, will be validly issued, fully paid and
nonassessable, free and clear of all Liens imposed by the Company. The Company has reserved from its duly authorized capital stock
a number of shares of Common Stock for issuance of the Underlying Shares at least equal to the Required Minimum on the date hereof.

 

(g)        Capitalization.
The capitalization of the Company is as set forth in the SEC Reports. The Company has not issued any capital stock since its most
recently filed periodic report under the Exchange Act, other than pursuant to the exercise of employee stock options under
the Company’s stock option plans, the issuance of shares of Common Stock to employees pursuant to the Company’s employee
stock purchase plans and pursuant to the conversion and/or exercise of Common Stock Equivalents outstanding as of the date of the
most recently filed periodic report under the Exchange Act. No Person has any right of first refusal, preemptive right, right of
participation, or any similar right to participate in the transactions contemplated by the Transaction Documents. Except as a result
of the purchase and sale of the Securities, there are no outstanding options, warrants, scrip rights to subscribe to, calls or
commitments of any character whatsoever relating to, or securities, rights or obligations convertible into or exercisable or exchangeable
for, or giving any Person any right to subscribe for or acquire any shares of Common Stock, or contracts, commitments, understandings
or arrangements by which the Company or any Subsidiary is or may become bound to issue additional shares of Common Stock or Common
Stock Equivalents. The issuance and sale of the Securities will not obligate the Company to issue shares of Common Stock or other
securities to any Person (other than the Purchasers) and will not result in a right of any holder of Company securities to adjust
the exercise, conversion, exchange or reset price under any of such securities. All of the outstanding shares of capital stock
of the Company are duly authorized, validly issued, fully paid and nonassessable, have been issued in material compliance with
all federal and state securities laws, and none of such outstanding shares was issued in violation of any preemptive rights or
similar rights to subscribe for or purchase securities. No further approval or authorization of any stockholder, the Board of Directors
or others is required for the issuance and sale of the Securities. There are no stockholders agreements, voting agreements or other
similar agreements with respect to the Company’s capital stock to which the Company is a party or, to the knowledge of the
Company, between or among any of the Company’s stockholders.

Reports complied in all material respects with the requirements of the Securities Act and the Exchange Act, as applicable, and
none of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were
made, not misleading. The financial statements of the Company included in the SEC Reports comply in all material respects with
applicable accounting requirements and the rules and regulations of the Commission with respect thereto as in effect at the time
of filing. Such financial statements have been prepared in accordance with United States generally accepted accounting principles
applied on a consistent basis during the periods involved (“GAAP”), except as may be otherwise specified in
such financial statements or the notes thereto and except that unaudited financial statements may not contain all footnotes required
by GAAP, and fairly present in all material respects the financial position of the Company and its consolidated Subsidiaries as
of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited
statements, to normal, immaterial, year-end audit adjustments.

 

(i)        Material
Changes; Undisclosed Events, Liabilities or Developments. Since the date of the latest audited financial statements included

Except for the issuance of the Securities contemplated by this Agreement or as set forth on Schedule 3.1(i), no event, liability,
fact, circumstance, occurrence or development has occurred or exists or is reasonably expected to occur or exist with respect to
the Company or its Subsidiaries or their respective businesses, properties, operations, assets or financial condition, that would
be required to be disclosed by the Company under applicable securities laws at the time this representation is made or deemed made
that has not been publicly disclosed at least 1 Trading Day prior to the date that this representation is made.

(j)        Litigation.
Except as described in the SEC Reports, there is no action, suit, inquiry, notice of violation, proceeding or investigation pending
or, to the knowledge of the Company, threatened against or affecting the Company, any Subsidiary or any of their respective properties

or foreign) (collectively, an “Action”) which (i) adversely affects or challenges the legality, validity or
enforceability of any of the Transaction Documents or the Securities or (ii) could, if there were an unfavorable decision, have
or reasonably be expected to result in a Material Adverse Effect. Except as set forth in the SEC Reports, since August 1, 2010,
neither the Company nor any Subsidiary, nor any director or officer thereof, is or has been the subject of any Action involving
a claim of violation of or liability under federal or state securities laws or a claim of breach of fiduciary duty. There has not
been, and to the knowledge of the Company, there is not pending or contemplated, any investigation by the Commission involving
the Company or any current or former director or officer of the Company. The Commission has not issued any stop order or other
order suspending the effectiveness of any registration statement filed by the Company or any Subsidiary under the Exchange Act
or the Securities Act.

 

(k)        Labor
Relations. No labor dispute exists or, to the knowledge of the Company, is imminent with respect to any of the employees of
the Company, which could reasonably be expected to result in a Material Adverse Effect. None of the Company’s or its Subsidiaries’
employees is a member of a union that relates to such employee’s relationship with the Company or such Subsidiary, and neither
the Company nor any of its Subsidiaries is a party to a collective bargaining agreement, and the Company and its Subsidiaries believe
that their relationships with their employees are good. To the knowledge of the Company, no executive officer of the Company or
any Subsidiary, is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure
or proprietary information agreement or non-competition agreement, or any other contract or agreement or any restrictive covenant
in favor of any third party, and the continued employment of each such executive officer does not subject the Company or any of
its Subsidiaries to any liability with respect to any of the foregoing matters. The Company and its Subsidiaries are in compliance
with all U.S. federal, state, local and foreign laws and regulations relating to employment and employment practices, terms and
conditions of employment and wages and hours, except where the failure to be in compliance could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect.

(l)        Compliance.

waived that, with notice or lapse of time or both, would result in a default by the Company or any Subsidiary under), nor has the
Company or any Subsidiary received notice of a claim that it is in default under or that it is in violation of, any indenture,
loan or credit agreement or any other agreement or instrument to which it is a party or by which it or any of its properties is
bound (whether or not such default or violation has been waived), (ii) is in violation of any judgment, decree or order of any
court, arbitrator or other governmental authority or (iii) is or has been in violation of any statute, rule, ordinance or regulation
of any governmental authority, including without limitation all foreign, federal, state and local laws relating to taxes, environmental
protection, occupational health and safety, product quality and safety and employment and labor matters, except in each case as
could not have or reasonably be expected to result in a Material Adverse Effect.

 

(m)        Regulatory
Permits. The Company and the Subsidiaries possess all certificates, authorizations and permits issued by the appropriate federal,
state, local or foreign regulatory authorities necessary to conduct their respective businesses as described in the SEC Reports,
except where the failure to possess such permits could not reasonably be expected to result in a Material Adverse Effect (“Material
Permits”), and neither the Company nor any Subsidiary has received any notice of proceedings relating to the revocation
or modification of any Material Permit.

 

(n)        Title
to Assets. Except as set forth on Schedule 3.1(n), the Company and the Subsidiaries have good and marketable title in
fee simple to all real property owned by them and good and marketable title in all personal property owned by them that is material
to the business of the Company and the Subsidiaries, in each case free and clear of all Liens, except for (i) Liens as do not materially
affect the value of such property and do not materially interfere with the use made and proposed to be made of such property by
the Company and the Subsidiaries and (ii) Liens for the payment of federal, state or other taxes, for which appropriate reserves
have been made in accordance with GAAP and, the payment of which is neither delinquent nor subject to penalties. Any real property
and facilities held under lease by the Company and the Subsidiaries are held by them under valid, subsisting and enforceable leases
with which the Company and the Subsidiaries are in compliance.

(o)        Intellectual
Property. The Company and the Subsidiaries have, or have rights to use, all patents, patent applications, trademarks, trademark
applications, service marks, trade names, trade secrets, inventions, copyrights, licenses and other intellectual property rights
and similar rights as described in the SEC Reports as necessary or required for use in connection with their respective businesses
and which the failure to so have could have a Material Adverse Effect (collectively, the “Intellectual Property Rights”).
None of, and neither the Company nor any Subsidiary has received a notice (written or otherwise) that any of, the Intellectual
Property Rights has expired, terminated or been abandoned, or is expected to expire or terminate or be abandoned, within two (2)
years from the date of this Agreement. Neither the Company nor any Subsidiary has received, since the date of the latest audited
financial statements included within the SEC Reports, a written notice of a claim or otherwise has any knowledge that the Intellectual
Property Rights violate or infringe upon the rights of any Person, except as could not have or reasonably be expected to not have
a Material Adverse Effect. To the knowledge of the Company, all such Intellectual Property Rights are enforceable and there is
no existing infringement by another Person of any of the Intellectual Property Rights. The Company and its Subsidiaries have taken
reasonable security measures to protect the secrecy, confidentiality and value of all of their intellectual properties, except
where failure to do so could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

The Company and the Subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and
in such amounts as are prudent and customary in the businesses in which the Company and the Subsidiaries are engaged, including,
but not limited to, directors and officers insurance coverage at least equal to the aggregate Subscription Amount. Neither the
Company nor any Subsidiary has any reason to believe that it will not be able to renew its existing insurance coverage as and when
such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business without
a significant increase in cost.

 

(q)        Transactions
With Affiliates and Employees. Except as set forth in the SEC Reports, none of the officers or directors of the Company or

in excess of $120,000 other than for: (i) payment of salary or consulting fees for services rendered, (ii) reimbursement for expenses
incurred on behalf of the Company and (iii) other employee benefits, including stock option agreements under any stock option plan
of the Company.

Internal Accounting Controls. The Company and the Subsidiaries are in compliance with any and all applicable requirements of
the Sarbanes-Oxley Act of 2002 that are effective as of the date hereof, and any and all applicable rules and regulations promulgated
by the Commission thereunder that are effective as of the date hereof and as of the Closing Date. The
Company and the Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurance that:
(i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded
as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability, (iii)
access to assets is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded
accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect
to any differences. The Company and the Subsidiaries have established disclosure controls and procedures (as defined in Exchange
Act Rules 13a-15(e) and 15d-15(e)) for the Company and the Subsidiaries and designed such disclosure controls and procedures to
ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded,
processed, summarized and reported, within the time periods specified in the Commission’s rules and forms. The Company’s
certifying officers have evaluated the effectiveness of the disclosure controls and procedures of the Company and the Subsidiaries
as of the end of the period covered by the most recently filed periodic report under the Exchange Act (such date, the “Evaluation
Date”). The Company presented in its most recently filed periodic report under the Exchange Act the conclusions of the
certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation
Date. Since the Evaluation Date, there have been no changes in the internal control over financial reporting (as such term is defined
in the Exchange Act) of the Company and its Subsidiaries that have materially affected, or is reasonably likely to materially affect,
the internal control over financial reporting of the Company and its Subsidiaries.

 

(s)        Certain
Fees. No brokerage or finder’s fees or commissions are or will be payable by the Company or any Subsidiary to any broker,
financial advisor or consultant, finder, placement agent, investment banker, bank or other Person with respect to the transactions

amended. The Company shall conduct its business in a manner so that it will not become an “investment company” subject
to registration under the Investment Company Act of 1940, as amended.

Company has taken no action designed to, or which to its knowledge is likely to have the effect of, terminating the registration
of the Common Stock under the Exchange Act nor has the Company received any notification that the Commission is contemplating terminating
such registration. The Company has not, in the 12 months preceding the date hereof, received notice from any Trading Market on
which the Common Stock is or has been listed or quoted to the effect that the Company is not in compliance with the listing or
maintenance requirements of such Trading Market. The Company is, and has no reason to believe that it will not in the foreseeable
future continue to be, in compliance with all such listing and maintenance requirements.

 

(w)        Application
of Takeover Protections. The Company and the Board of Directors have taken all necessary action, if any, in order to render
inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement)
or other similar anti-takeover provision under the Company’s certificate of incorporation (or similar charter documents)
or the laws of its state of incorporation that is or could become applicable to the Purchasers as a result of the Purchasers and
the Company fulfilling their obligations or exercising their rights under the Transaction Documents, including without limitation
as a result of the Company’s issuance of the Securities and the Purchasers’ ownership of the Securities.

 

(x)        Disclosure.
Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents, the Company
confirms that neither it nor any other Person acting on its behalf has provided any of the Purchasers or their agents or counsel
with any information that it believes constitutes or might constitute material, non-public information. The Company understands
and confirms that the Purchasers will rely on the foregoing representation in effecting transactions in securities of the Company.
All of the disclosure furnished by or on behalf of the Company to the Purchasers regarding the Company and its Subsidiaries, their
respective businesses and the transactions contemplated hereby, including the Disclosure Schedules to this Agreement, when taken
together as a whole, is true and correct and does not contain any untrue statement of a material fact or omit to state any material
fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading.

not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary
in order to make the statements therein, in light of the circumstances under which they were made and when made, not misleading.
The Company acknowledges and agrees that no Purchaser makes or has made any representations or warranties with respect to the transactions
contemplated hereby other than those specifically set forth in Section 3.2 hereof.

Integrated Offering. Assuming the accuracy of the Purchasers’ representations and warranties set forth in Section 3.2,
neither the Company, nor any of its Affiliates, nor any Person acting on its or their behalf has, directly or indirectly, made
any offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering
of the Securities to be integrated with prior offerings by the Company for purposes of: (i) the Securities Act which would require

(z)        Solvency.
Based on the consolidated financial condition of the Company as of the Closing Date, and the Company’s good faith estimate
of the fair market value of its assets, after giving effect to the receipt by the Company of the proceeds from the sale of the
Securities hereunder: (i) the fair saleable value of the Company’s assets exceeds the amount that will be required to be
paid on or in respect of the Company’s existing debts and other liabilities (including known contingent liabilities) as they
mature, (ii) the Company’s assets do not constitute unreasonably small capital to carry on its business as now conducted
and as proposed to be conducted including its capital needs taking into account the particular capital requirements of the business
conducted by the Company, consolidated and projected capital requirements and capital availability thereof, and (iii) the current
cash flow of the Company, together with the proceeds the Company would receive, were it to liquidate all of its assets, after taking
into account all anticipated uses of the cash, would be sufficient to pay all amounts on or in respect of its liabilities when
such amounts are required to be paid. The Company does not intend to incur debts beyond its ability to pay such debts as they mature
(taking into account the timing and amounts of cash to be payable on or in respect of its debt). The Company has no knowledge of
any facts or circumstances which lead it to believe that it will file for reorganization or liquidation under the bankruptcy or
reorganization laws of any jurisdiction within one year from the Closing Date. Schedule 3.1(z) sets forth as of the date
hereof all outstanding secured and unsecured Indebtedness of the Company or any Subsidiary, or for which the Company or any Subsidiary
has commitments. For the purposes of this Agreement, “Indebtedness” means (x) any liabilities for borrowed money
or amounts owed in excess of $250,000 (other than trade accounts payable incurred in the ordinary course of business), (y) all
guaranties, endorsements and other contingent obligations in respect of indebtedness of others, whether or not the same are or
should be reflected in the Company’s consolidated balance sheet (or the notes thereto), except guaranties by endorsement
of negotiable instruments for deposit or collection or similar transactions in the ordinary course of business; and (z) the present
value of any lease payments in excess of $250,000 due under leases required to be capitalized in accordance with GAAP. Neither
the Company nor any Subsidiary is in default with respect to any Indebtedness.

 

(aa)        Tax
Status.         Except for matters that would not,
individually or in the aggregate, have or reasonably be expected to result in a Material Adverse Effect, the Company and its Subsidiaries
each (i) has made or filed all United States federal, state and local income and all foreign income and franchise tax returns,
reports and declarations required by any jurisdiction to which it is subject, (ii) has paid all taxes and other governmental assessments
and charges that are material in amount, shown or determined to be due on such returns, reports and declarations and (iii) has
set aside on its books provision reasonably adequate for the payment of all material taxes for periods subsequent to the periods
to which such returns, reports or declarations apply. There are no unpaid taxes in any material amount claimed to be due by the
taxing authority of any jurisdiction, and the officers of the Company or of any Subsidiary know of no basis for any such claim.

(bb)        Foreign
Corrupt Practices. Neither the Company nor any Subsidiary, nor to the knowledge of the Company or any Subsidiary, any agent

contributions, gifts, entertainment or other unlawful expenses related to foreign or domestic political activity, (ii) made any
unlawful payment to foreign or domestic government officials or employees or to any foreign or domestic political parties or campaigns
from corporate funds, (iii) failed to disclose fully any contribution made by the Company or any Subsidiary (or made by any person
acting on its behalf of which the Company is aware) which is in violation of law or (iv) violated in any material respect any provision
of FCPA.

 

(cc)        Accountants.
The Company’s accounting firm is set forth on Schedule 3.1(cc) of the Disclosure Schedules. To the knowledge and belief
of the Company, such accounting firm: (i) is a registered public accounting firm as required by the Exchange Act and (ii) shall
express its opinion with respect to the financial statements to be included in the Company’s Annual Report for the fiscal
year ending July 31, 2012.

thereby. The Company further acknowledges that no Purchaser is acting as a financial advisor or fiduciary of the Company (or in
any similar capacity) with respect to the Transaction Documents and the transactions contemplated thereby and any advice given
by any Purchaser or any of their respective representatives or agents in connection with the Transaction Documents and the transactions
contemplated thereby is merely incidental to the Purchasers’ purchase of the Securities. The Company further represents to
each Purchaser that the Company’s decision to enter into this Agreement and the other Transaction Documents has been based

for any specified term, (ii) past or future open market or other transactions by any Purchaser, specifically including, without
limitation, Short Sales or “derivative” transactions, before or after the closing of this or future private placement
transactions, may negatively impact the market price of the Company’s publicly-traded securities, (iii) any Purchaser, and
counter-parties in “derivative” transactions to which any such Purchaser is a party, directly or indirectly, may presently

understands and acknowledges that (y) one or more Purchasers may engage in hedging activities at various times during the period
that the Securities are outstanding, including, without limitation, during the periods that the value of the Underlying Shares
deliverable with respect to Securities are being determined, and (z) such hedging activities (if any) could reduce the value of
the existing stockholders' equity interests in the Company at and after the time that the hedging activities are being conducted. 
The Company acknowledges that such aforementioned hedging activities do not constitute a breach of any of the Transaction Documents.

with the terms of the Company’s stock option plan and (ii) with an exercise price at least equal to the fair market value

3.2         Representations
and Warranties of the Purchasers. Each Purchaser, for itself and for no other Purchaser, hereby represents and warrants as
of the date hereof and as of the Closing Date to the Company as follows (unless as of a specific date therein):

 

(a)        Organization;
Authority. Such Purchaser is either an individual or an entity duly incorporated or formed, validly existing and in good standing
under the laws of the jurisdiction of its incorporation or formation with full right, corporate, partnership, limited liability
company or similar power and authority to enter into and to consummate the transactions contemplated by the Transaction Documents
and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of the Transaction Documents and
performance by such Purchaser of the transactions contemplated by the Transaction Documents have been duly authorized by all necessary
corporate, partnership, limited liability company or similar action, as applicable, on the part of such Purchaser. Each Transaction
Document to which it is a party has been duly executed by such Purchaser, and when delivered by such Purchaser in accordance with
the terms hereof, will constitute the valid and legally binding obligation of such Purchaser, enforceable against it in accordance
with its terms, except: (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium
and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating
to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification
and contribution provisions may be limited by applicable law.

 

(b)        Understandings
or Arrangements. Such Purchaser understands that the Securities are “restricted securities” and have not been registered
under the Securities Act or any applicable state securities law and is acquiring the Securities as principal for its own account
and not with a view 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 (this representation and warranty not limiting such Purchaser’s right to sell the Securities pursuant to a Registration
Statement or otherwise in compliance with applicable federal and state securities laws). Such Purchaser is acquiring the Securities
hereunder in the ordinary course of its business.

 

(c)        Purchaser
Status. At the time such Purchaser was offered the Securities, it was, and as of the date hereof it is, and on each date on
which it exercises any Warrants or converts any shares of Preferred Stock it will be either: (i) an “accredited investor”
as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the Securities Act or (ii) a “qualified institutional
buyer” as defined in Rule 144A(a) under the Securities Act. Such Purchaser is not required to be registered as a broker-dealer
under Section 15 of the Exchange Act.

 

    	22

    	 

    

 

(d)        Experience
of Such Purchaser. Such Purchaser, either alone or together with its representatives, has such knowledge, sophistication and
experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment
in the Securities, and has so evaluated the merits and risks of such investment. Such Purchaser is able to bear the economic risk
of an investment in the Securities and, at the present time, is able to afford a complete loss of such investment.

 

(e)        Certain
Transactions and Confidentiality. Other than consummating the transactions contemplated hereunder, such Purchaser has not directly
or indirectly, nor has any Person acting on behalf of or pursuant to any understanding with such Purchaser, executed any purchases
or sales, including Short Sales, of the securities of the Company during the period commencing as of the time that
such Purchaser first received a term sheet (written or oral) from the Company or any other Person representing the Company setting
forth the material terms of the transactions contemplated hereunder and ending immediately prior to the execution hereof.
Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio
managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment
decisions made by the portfolio managers managing other portions of such Purchaser’s assets, the representation set forth
above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision
to purchase the Securities covered by this Agreement. Other than to other Persons party to this Agreement, such Purchaser has maintained
the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this
transaction). Notwithstanding the foregoing, for avoidance of doubt, nothing contained herein shall constitute a representation
or warranty, or preclude any actions, with respect to the identification of the availability of, or securing of, available shares
to borrow in order to effect Short Sales or similar transactions in the future.

 

The Company acknowledges and agrees that the
representations contained in Section 3.2 shall not modify, amend or affect such Purchaser’s right to rely on the Company’s
representations and warranties contained in this Agreement or any representations and warranties contained in any other Transaction
Document or any other document or instrument executed and/or delivered in connection with this Agreement or the consummation of
the transaction contemplated hereby.

ARTICLE IV. 

OTHER AGREEMENTS OF THE PARTIES

 

4.1          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, to the Company or to an Affiliate of a Purchaser or in
connection with a pledge as contemplated in Section 4.1(b), 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 the Registration Rights Agreement and shall have the rights and obligations of a Purchaser under this
Agreement and the Registration Rights Agreement.

 

(b)        The
Purchasers agree to the imprinting, so long as is required by this Section 4.1, of a legend on any of the Securities 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 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.
THIS SECURITY [AND THE SECURITIES ISSUABLE UPON [EXERCISE] [CONVERSION] OF THIS SECURITY] MAY BE PLEDGED IN CONNECTION WITH A BONA
FIDE MARGIN ACCOUNT WITH A REGISTERED BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION THAT IS AN “ACCREDITED INVESTOR”
AS DEFINED IN RULE 501(a) UNDER THE SECURITIES ACT OR OTHER LOAN SECURED BY SUCH SECURITIES.

 

The Company acknowledges
and agrees that a Purchaser may from time to time pledge pursuant to a bona fide margin agreement with a registered broker-dealer
or grant a security interest in some or all of the Securities to a financial institution that is an “accredited investor”
as defined in Rule 501(a) under the Securities Act and who agrees to be bound by the provisions of this Agreement and the Registration
Rights Agreement and, if required under the terms of such arrangement, such Purchaser may transfer pledged or secured Securities
to the pledgees or secured parties. Such a pledge or transfer would not be subject to approval of the Company and no legal opinion
of legal counsel of the pledgee, secured party or pledgor shall be required in connection therewith. Further, no notice shall be
required of such pledge. At the appropriate Purchaser’s expense, the Company will execute and deliver such reasonable documentation
as a pledgee or secured party of Securities may reasonably request in connection with a pledge or transfer of the Securities, including,
if the Securities are subject to registration pursuant to the Registration Rights Agreement, the preparation and filing of any
required prospectus supplement under Rule 424(b)(3) under the Securities Act or other applicable provision of the Securities Act
to appropriately amend the list of selling stockholders thereunder.

 

    	24

    	 

    

 

(c)        Certificates
evidencing the Underlying Shares shall not contain any legend (including the legend set forth in Section 4.1(b) hereof): (i) while
a registration statement (including the Registration Statement) covering the resale of such security is effective under the Securities
Act, (ii) following any sale of such Underlying Shares pursuant to Rule 144, (iii) if such Underlying 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 Underlying Shares and without volume or manner-of-sale restrictions or (iv) if such legend is not required
under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff
of the Commission). The Company shall cause its counsel to issue a legal opinion to the Transfer Agent promptly after the Effective
Date if required by the Transfer Agent to effect the removal of the legend hereunder. If all or any shares of Preferred Stock are
converted or any portion of a Warrant is exercised at a time when there is an effective registration statement to cover the resale
of the Underlying Shares, or if such Underlying Shares may be sold under Rule 144 or if such legend is not otherwise required under
applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the
Commission) then such Underlying Shares shall be issued free of all legends. The Company agrees that following such time as such
legend is no longer required under this Section 4.1(c), it will, no later than three Trading Days following the delivery by a Purchaser
to the Company or the Transfer Agent of a certificate representing Underlying Shares, as applicable, issued with a restrictive
legend (such third Trading Day, the “Legend Removal Date”), deliver or cause to be delivered to such Purchaser
a certificate representing such shares that is free from all restrictive and other legends. The Company may not make any notation
on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 4.
Certificates for Underlying Shares subject to legend removal hereunder shall be transmitted by the Transfer Agent to the Purchaser
by crediting the account of the Purchaser’s prime broker with the Depository Trust Company System as directed by such Purchaser.

 

(d)        In
addition to such Purchaser’s other available remedies, the Company shall pay to a Purchaser, in cash, as partial liquidated
damages and not as a penalty, for each $1,000 of Underlying Shares (based on the VWAP of the Common Stock on the date such Securities
are submitted to the Transfer Agent) delivered for removal of the restrictive legend and subject to Section 4.1(c), $10 per Trading
Day (increasing to $20 per Trading Day five (5) Trading Days after such damages have begun to accrue) for each Trading Day after
the Legend Removal Date until such certificate is delivered without a legend. Nothing herein shall limit such Purchaser’s
right to pursue actual damages for the Company’s failure to deliver certificates representing any Securities as required
by the Transaction Documents, and such Purchaser shall have the right to pursue all remedies available to it at law or in equity
including, without limitation, a decree of specific performance and/or injunctive relief.

 

    	25

    	 

    

 

(e)        Each
Purchaser, severally and not jointly with the other Purchasers, agrees with the Company that such Purchaser will sell any Securities
pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements,
or an exemption therefrom, and that if Securities are sold pursuant to a Registration Statement, they will be sold in compliance
with the plan of distribution set forth therein, and acknowledges that the removal of the restrictive legend from certificates
representing Securities as set forth in this Section 4.1 is predicated upon the Company’s reliance upon this understanding.

 

4.2         Acknowledgment
of Dilution. The Company acknowledges that the issuance of the Securities may result in dilution of the outstanding shares
of Common Stock, which dilution may be substantial under certain market conditions. The Company further acknowledges that its obligations
under the Transaction Documents, including, without limitation, its obligation to issue the Underlying Shares pursuant to the Transaction
Documents, are unconditional and absolute and not subject to any right of set off, counterclaim, delay or reduction, regardless
of the effect of any such dilution or any claim the Company may have against any Purchaser and regardless of the dilutive effect
that such issuance may have on the ownership of the other stockholders of the Company.

 

4.3        Furnishing
of Information; Public Information.

 

(a)        Until
the earliest of the time that (i) no Purchaser owns Securities or (ii) the Warrants have expired, the Company covenants to maintain
the registration of the Common Stock under Section 12(b) or 12(g) of the Exchange Act and to timely file (or obtain extensions
in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date
hereof pursuant to the Exchange Act even if the Company is not then subject to the reporting requirements of the Exchange Act.

 

(b)        At
any time during the period commencing from the six (6) month anniversary of the date hereof and ending at such time that all of
the Securities may be sold without the requirement for the Company to be in compliance with Rule 144(c)(1) and otherwise without
restriction or limitation pursuant to Rule 144, if the Company shall fail for any reason to satisfy the current public information
requirement under Rule 144(c) (a “Public Information Failure”) then, in addition to such Purchaser’s other available
remedies, the Company shall pay to a Purchaser, in cash, as partial liquidated damages and not as a penalty, by reason of any such
delay in or reduction of its ability to sell the Securities, an amount in cash equal to two percent (2.0%) of the aggregate Stated
Value of Preferred Stock held by such Purchaser on the day of a Public Information Failure and on every thirtieth (30th) day (pro
rated for periods totaling less than thirty days) thereafter until the earlier of (a) the date such Public Information Failure
is cured and (b) such time that such public information is no longer required for the Purchasers to transfer the Underlying Shares
pursuant to Rule 144. The payments to which a Purchaser shall be entitled pursuant to this Section 4.3(b) are referred to herein
as “Public Information Failure Payments.” Public Information Failure Payments shall be paid on the earlier of
(i) the last day of the calendar month during which such Public Information Failure Payments are incurred and (ii) the third (3rd)
Business Day after the event or failure giving rise to the Public Information Failure Payments is cured. In the event the Company
fails to make Public Information Failure Payments in a timely manner, such Public Information Failure Payments shall bear interest
at the rate of 1.5% per month (prorated for partial months) until paid in full. Nothing herein shall limit such Purchaser’s
right to pursue actual damages for the Public Information Failure, and such Purchaser shall have the right to pursue all remedies
available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief.

 

    	26

    	 

    

 

 

4.4           Integration.
The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined
in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities in a manner that would require
the registration under the Securities Act of the sale of the Securities or that would be integrated with the offer or sale of the
Securities for purposes of the rules and regulations of any Trading Market such that it would require shareholder approval prior
to the closing of such other transaction unless shareholder approval is obtained before the closing of such subsequent transaction.

 

4.5           Conversion
and Exercise Procedures. Each of the form of Notice of Exercise included in the Warrants and the form of Notice of Conversion
included in the Certificate of Designation set forth the totality of the procedures required of the Purchasers in order to exercise
the Warrants or convert the Preferred Stock. No additional legal opinion, other information or instructions shall be required of
the Purchasers to exercise their Warrants or convert their Preferred Stock. The Company shall honor exercises of the Warrants and
conversions of the Preferred Stock and shall deliver Underlying Shares in accordance with the terms, conditions and time periods
set forth in the Transaction Documents.

date hereof, issue a press release disclosing the material terms of the transactions contemplated hereby, and shall file a Current

after the issuance of such press release, the Company represents to the Purchasers that it shall have publicly disclosed all material,
non-public information delivered to any of the Purchasers by the Company or any of its Subsidiaries, or any of their respective
officers, directors, employees or agents in connection with the transactions contemplated by the Transaction Documents. The Company
and each Purchaser shall consult with each other in issuing any other press releases with respect to the transactions contemplated
hereby, and neither the Company nor any Purchaser shall issue any such press release nor otherwise make any such public statement
without the prior consent of the Company, with respect to any press release of any Purchaser, or without the prior consent of each
Purchaser, with respect to any press release of the Company, which consent shall not unreasonably be withheld or delayed, except
if such disclosure is required by law, in which case the disclosing party shall promptly provide the other party with prior notice
of such public statement or communication. Notwithstanding the foregoing, the Company shall not publicly disclose the name of any
Purchaser, or include the name of any Purchaser in any filing with the Commission or any regulatory agency or Trading Market, without
the prior written consent of such Purchaser, except: (a) as required by federal securities law in connection with the filing of
final Transaction Documents with the Commission and (b) to the extent such disclosure is required by law or Trading Market regulations,
in which case the Company shall provide the Purchasers with prior notice of such disclosure permitted under this clause (b).

4.7           Shareholder
Rights Plan. No claim will be made or enforced by the Company or, with the consent of the Company, any other Person, that any
Purchaser is an “Acquiring Person” under any control share acquisition, business combination, poison pill (including
any distribution under a rights agreement) or similar anti-takeover plan or arrangement in effect or hereafter adopted by the Company,
or that any Purchaser could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving Securities
under the Transaction Documents or under any other agreement between the Company and the Purchasers.

 

4.8           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 any Purchaser or its
agents or counsel with any information that the Company believes constitutes material non-public information, unless prior thereto
such Purchaser shall have entered into a written agreement with the Company regarding the confidentiality and use of such information.
The Company understands and confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions in
securities of the Company.

 

4.9           Use
of Proceeds. Except as set forth on Schedule 4.9 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: (a) for 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) for the redemption of any Common Stock or Common Stock Equivalents, (c) for the settlement of any outstanding litigation
or (d) in violation of FCPA or OFAC regulations.

4.10        Indemnification
of Purchasers. Subject to the provisions of this Section 4.10, the Company will indemnify and hold each Purchaser and its directors,
officers, shareholders, members, partners, employees and agents (and any other Persons with a functionally equivalent role of a
Person holding such titles notwithstanding a lack of such title or any other title), each Person who controls such Purchaser (within
the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, shareholders,
agents, members, partners or employees (and any other Persons with a functionally equivalent role of a Person holding such titles
notwithstanding a lack of such title or any other title) of such controlling persons (each, a “Purchaser Party”)
harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments,
amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation that any such Purchaser
Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or
agreements made by the Company in this Agreement or in the other Transaction Documents or (b) any action instituted against Purchaser
Parties in any capacity, or any of them or their respective Affiliates, by any stockholder of the Company who is not an Affiliate
of such Purchaser Party, with respect to any of the transactions contemplated by the Transaction Documents (unless such action
is based upon a breach of such Purchaser Party’s representations, warranties or covenants under the Transaction Documents
or any agreements or understandings such Purchaser Party may have with any such stockholder or any violations by such Purchaser
Party of state or federal securities laws or any conduct by such Purchaser Party which constitutes fraud, gross negligence, willful
misconduct or malfeasance). If any action shall be brought against any Purchaser Party in respect of which indemnity may be sought
pursuant to this Agreement, such Purchaser Party shall promptly notify the Company in writing, and the Company shall have the right
to assume the defense thereof with counsel of its own choosing reasonably acceptable to the Purchaser Party. Any Purchaser Party
shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses
of such counsel shall be at the expense of such Purchaser Party except to the extent that (i) the employment thereof has been specifically
authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time to assume such defense and
to employ counsel or (iii) in such action there is, in the reasonable opinion of counsel, a material conflict on any material issue
between the position of the Company and the position of such Purchaser Party, in which case the Company shall be responsible for
the reasonable fees and expenses of no more than one such separate counsel. The Company will not be liable to any Purchaser Party
under this Agreement (y) for any settlement by a Purchaser Party effected without the Company’s prior written consent, which
shall not be unreasonably withheld or delayed; or (z) to the extent, but only to the extent that a loss, claim, damage or liability
is attributable to any Purchaser Party’s breach of its representations, warranties or covenants under the Transaction Documents
or any agreements or understandings such Purchaser Party may have with any such stockholder or any violations by such Purchaser
Party of state or federal securities laws or any conduct by such Purchaser Party which constitutes fraud, gross negligence, willful
misconduct or malfeasance. The indemnification required by this Section 4.10 shall be made by periodic payments of the amount thereof
during the course of the investigation or defense, as and when bills are received or are incurred. The indemnity agreements contained
herein shall be in addition to any cause of action or similar right of any Purchaser Party against the Company or others and any
liabilities the Company may be subject to pursuant to law.

 

4.11        Reservation
and Listing of Securities.

 

(a)        The
Company shall maintain a reserve from its duly authorized shares of Common Stock for issuance pursuant to the Transaction Documents
in such amount as may then be required to fulfill its obligations in full under the Transaction Documents.

 

(b)        If,
on any date, the number of authorized but unissued (and otherwise unreserved) shares of Common Stock is less than the Required
Minimum on such date, then the Board of Directors shall use commercially reasonable efforts to amend the Company’s certificate
or articles of incorporation to increase the number of authorized but unissued shares of Common Stock to at least the Required
Minimum at such time, as soon as possible and in any event not later than the 75th day after such date.

 

    	29

    	 

    

 

(c)        The
Company shall, if applicable: (i) in the time and manner required by the principal Trading Market, prepare and file with such Trading
Market an additional shares listing application covering a number of shares of Common Stock at least equal to the Required Minimum
on the date of such application, (ii) take all steps necessary to cause such shares of Common Stock to be approved for listing
or quotation on such Trading Market as soon as possible thereafter, (iii) provide to the Purchasers evidence of such listing or
quotation and (iv) maintain the listing or quotation of such Common Stock on any date at least equal to the Required Minimum on
such date on such Trading Market or another Trading Market.

 

4.12        Participation
in Future Financing.

 

(a)        Subject
only to the rights of investors party to that certain securities purchase agreement dated July 8, 2011, from the date hereof until
the date that is the 12 month anniversary of the Closing Date, upon any proposed issuance by the Company or any of its Subsidiaries
of Common Stock, Common Stock Equivalents for cash consideration, Indebtedness or a combination thereof, other than (i) a rights
offering to all holders of Common Stock (which may include extending such rights offering to holders of Preferred Stock) or (ii)
issuance of shares of Common Stock for the purpose of paying bona fide non-Affiliate vendors of goods and services to the
Company at fair market value at the time of issuance (not to exceed $75,000 per calendar quarter through the earlier of June 30,
2012 or all of the Preferred Stock has been converted), (a “Subsequent Financing”), each Purchaser shall have
the right to participate in up to an amount of the Subsequent Financing equal to 100% of the Subsequent Financing (the “Participation
Maximum”) on the same terms, conditions and price provided for in the Subsequent Financing, unless the Subsequent Financing
is an underwritten public offering, in which case the Company shall offer each Purchaser the right to participate in such public
offering when it is lawful for the Company to do so, but no Purchaser shall be entitled to purchase any particular amount of such
public offering.

 

(b)        At
least five (5) Trading Days prior to the closing of the Subsequent Financing, the Company shall deliver to each Purchaser a written
notice of its intention to effect a Subsequent Financing (“Pre-Notice”), which Pre-Notice shall ask such Purchaser
if it wants to review the details of such financing (such additional notice, a “Subsequent Financing Notice”).
Upon the request of a Purchaser, and only upon a request by such Purchaser, for a Subsequent Financing Notice, the Company shall
promptly, but no later than one (1) Trading Day after such request, deliver a Subsequent Financing Notice to such Purchaser. The
requesting Purchaser shall be deemed to have acknowledged that the Subsequent Financing Notice may contain material non-public
information. The Subsequent Financing Notice shall describe in reasonable detail the proposed terms of such Subsequent Financing,
the amount of proceeds intended to be raised thereunder and the Person or Persons through or with whom such Subsequent Financing
is proposed to be effected and shall include a term sheet or similar document relating thereto as an attachment.

 

(c)        Any
Purchaser desiring to participate in such Subsequent Financing must provide written notice to the Company by not later than 5:30
p.m. (New York City time) on the fifth (5th) Trading Day after all of the Purchasers have received the Pre-Notice that
the Purchaser is willing to participate in the Subsequent Financing, the amount of such Purchaser’s participation, and representing
and warranting that such Purchaser has such funds ready, willing, and available for investment on the terms set forth in the Subsequent
Financing Notice. If the Company receives no such notice from a Purchaser as of such fifth (5th) Trading Day, such Purchaser
shall be deemed to have notified the Company that it does not elect to participate.

 

    	30

    	 

    

 

(d)        If
by 5:30 p.m. (New York City time) on the fifth (5th ) Trading Day after all of the Purchasers have received the Pre-Notice,
notifications by the Purchasers of their willingness to participate in the Subsequent Financing (or to cause their designees to
participate) is, in the aggregate, less than the total amount of the Subsequent Financing, then the Company may effect the remaining
portion of such Subsequent Financing on the terms and with the Persons set forth in the Subsequent Financing Notice.

 

(e)        If
by 5:30 p.m. (New York City time) on the fifth (5th) Trading Day after all of the Purchasers have received the Pre-Notice,
the Company receives responses to a Subsequent Financing Notice from Purchasers seeking to purchase more than the aggregate amount
of the Participation Maximum, each such Purchaser shall have the right to purchase its Pro Rata Portion (as defined below) of the
Participation Maximum.  “Pro Rata Portion” means the ratio of (x) the Subscription Amount of Securities
purchased on the Closing Date by a Purchaser participating under this Section 4.12 and (y) the sum of the aggregate Subscription
Amounts of Securities purchased on the Closing Date by all Purchasers participating under this Section 4.12.

 

(f)        The
Company must provide the Purchasers with a second Subsequent Financing Notice, and the Purchasers will again have the right of
participation set forth above in this Section 4.12, if the Subsequent Financing subject to the initial Subsequent Financing Notice
is not consummated for any reason on the terms set forth in such Subsequent Financing Notice within thirty (30) Trading Days after
the date of the initial Subsequent Financing Notice.

 

(g)        The
Company and each Purchaser agree that if any Purchaser elects to participate in the Subsequent Financing, the transaction documents
related to the Subsequent Financing shall not include any term or provision whereby such Purchaser shall be required to agree to
any restrictions on trading as to any of the Securities purchased hereunder (for avoidance of doubt, the securities purchased in
the Subsequent Financing shall not be considered securities purchased hereunder) or be required to consent to any amendment to
or termination of, or grant any waiver, release or the like under or in connection with, this Agreement, without the prior written
consent of such Purchaser.

 

(h)        Notwithstanding
anything to the contrary in this Section 4.12 and unless otherwise agreed to by such Purchaser, the Company shall either confirm
in writing to such Purchaser that the transaction with respect to the Subsequent Financing has been abandoned or shall publicly
disclose its intention to issue the securities in the Subsequent Financing, in either case in such a manner such that such Purchaser
will not be in possession of any material, non-public information, by the tenth (10th) Business Day following delivery of the Subsequent
Financing Notice. If by such tenth (10th) Business Day, no public disclosure regarding a transaction with respect to the Subsequent
Financing has been made, and no notice regarding the abandonment of such transaction has been received by such Purchaser, such
transaction shall be deemed to have been abandoned and such Purchaser shall not be deemed to be in possession of any material,
non-public information with respect to the Company or any of its Subsidiaries.

 

    	31

    	 

    

 

(i)        Notwithstanding
the foregoing, this Section 4.12 shall not apply in respect of (i) an Exempt Issuance, (ii) an underwritten public offering of
Common Stock or (iii) shares of Common Stock issued in settlement of outstanding severance packages with former officers and directors
of the Company.

 

4.13       Subsequent
Equity Sales.

 

(a)        Except
as provided in paragraphs (c) and (d), below, From the date hereof until 60 days after the date the initial Registration Statement
is declared effective by the Commission, neither the Company nor any Subsidiary shall issue, enter into any agreement to issue
or announce the issuance or proposed issuance of any shares of Common Stock or Common Stock Equivalents.

 

(b)        From
the date hereof until the later of (i) the date that is the 12 month anniversary of the Closing Date and (ii) such time as not
more than 15% of the originally issued Preferred Stock remains outstanding, the Company shall be prohibited from effecting or entering
into an agreement to effect any issuance by the Company or any of its Subsidiaries of Common Stock or Common Stock Equivalents
for cash consideration (or a combination of units thereof) involving a Variable Rate Transaction. “Variable Rate Transaction”
means a transaction in which the Company (i) issues or sells any debt or equity securities that are convertible into, exchangeable
or exercisable for, or include the right to receive, additional shares of Common Stock either (A) at a conversion price, exercise
price or exchange rate or other price that is based upon, and/or varies with, the trading prices of or quotations for the shares
of Common Stock at any time after the initial issuance of such debt or equity securities or (B) with a conversion, exercise or
exchange price that is subject to being reset at some future date after the initial issuance of such debt or equity security or
upon the occurrence of specified or contingent events directly or indirectly related to the business of the Company or the market
for the Common Stock or (ii) enters into any agreement, including, but not limited to, an equity line of credit, whereby the Company
may sell securities at a future determined price. Any Purchaser shall be entitled to obtain injunctive relief against the Company
to preclude any such issuance, which remedy shall be in addition to any right to collect damages.

 

(c)        Notwithstanding
the foregoing, this Section 4.13 shall not apply in respect of (i) any rights offering, (ii) shares of Common Stock for the purpose
of paying bona fide non-Affiliate vendors of goods and services to the Company at fair market value at the time of issuance
(not to exceed $75,000 per calendar quarter through the earlier of June 30, 2012 or all of the Preferred Stock has been converted),
or (iii) any Exempt Issuance, except that no Variable Rate Transaction, other than the issuance of Common Stock upon exercise of
Warrants outstanding on the date hereof, shall be an Exempt Issuance.

 

    	32

    	 

    

 

(d)        Paragraph
4.13(a) shall not apply to the issuance of securities by the Company’s Subsidiary, Antigen Express, Inc. (“Antigen”),
the sale of Antigen securities by the Company or the distribution of Antigen securities to the Company’s stockholders.

 

4.14    
   Equal Treatment of Purchasers. 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 this Agreement unless the same consideration is also offered to all of the parties to this Agreement. For
clarification purposes, this provision constitutes a separate right granted to each Purchaser by the Company and negotiated
separately by each Purchaser, and is intended for the Company to treat the Purchasers as a class and shall not in any way be
construed as the Purchasers acting in concert or as a group with respect to the purchase, disposition or voting of Securities
or otherwise. 

 

4.15        Most
Favored Nation Provision. From the date hereof until such time as no Purchaser holds any of the Securities, in the event that
the Company issues or sells any Common Stock or Common Stock Equivalents, if a Purchaser then holding Securities reasonably believes
that any of the terms and conditions appurtenant to such issuance or sale are more favorable to such investors than are the terms
and conditions granted to the Purchasers hereunder, upon notice to the Company by such Purchaser within five Trading Days after
disclosure of such issuance or sale, the Company shall amend the terms of this transaction as to such Purchaser only so as to give
such Purchaser the benefit of such more favorable terms or conditions. This Section 4.15 shall not apply with respect to an Exempt
Issuance, and shall only apply as to price terms in respect of any rights offering, or in respect of issuances of Common Stock
to vendors as otherwise permitted in Sections 4.12 and 4.13. The Company shall provide each Purchaser with notice of any such issuance
or sale in the manner for disclosure of Subsequent Financings set forth in Section 4.12.

 

4.16        Certain
Transactions and Confidentiality. Each Purchaser, severally and not jointly with the other Purchasers, covenants that neither
it, nor any Affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases or sales, including
Short Sales, of any of the Company’s securities during the period commencing with the execution of this Agreement and ending
at such time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release
as described in Section 4.6.  Each Purchaser, severally and not jointly with the other Purchasers, covenants that until such
time as the transactions contemplated by this Agreement are publicly disclosed by the Company pursuant to the initial press release
as described in Section 4.6, such Purchaser will maintain the confidentiality of the existence and terms of this transaction and
the information included in the Transaction Documents and the Disclosure Schedules. Notwithstanding the foregoing, and notwithstanding
anything contained in this Agreement to the contrary, the Company expressly acknowledges and agrees that (i) no Purchaser makes
any representation, warranty or covenant hereby that it will not engage in effecting transactions in any securities of the Company
after the time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press
release as described in Section 4.6, (ii) no Purchaser shall be restricted or prohibited from effecting any transactions in any
securities of the Company in accordance with applicable securities laws from and after the time that the transactions contemplated
by this Agreement are first publicly announced pursuant to the initial press release as described in Section 4.6 and (iii) no Purchaser
shall have any duty of confidentiality to the Company or its Subsidiaries after the issuance of the initial press release as described
in Section 4.6.  Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby
separate portfolio managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct
knowledge of the investment decisions made by the portfolio managers managing other portions of such Purchaser’s assets,
the covenant set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made
the investment decision to purchase the Securities covered by this Agreement.

 

    	33

    	 

    

 

4.17           Capital
Changes. Until the one year anniversary of the Closing Date, the Company shall not undertake a reverse or forward stock split
or reclassification of the Common Stock without the prior written consent of the Purchasers holding a majority in interest of the
shares of Preferred Stock, unless such reverse split is made in conjunction with the listing of the Common Stock on a national
securities exchange.

 

4.18           Form
D; Blue Sky Filings. The Company agrees to timely file a Form D with respect to the Securities as required under Regulation
D and to provide a copy thereof, promptly upon request of any Purchaser. 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 Purchasers
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 Purchaser.

MISCELLANEOUS

 

5.1           Termination. 
This Agreement may be terminated by any Purchaser, as to such Purchaser’s obligations hereunder only and without any effect
whatsoever on the obligations between the Company and the other Purchasers, by written notice to the other parties, if the Closing
has not been consummated on or before February 7, 2012; provided, however, that such termination will not affect
the right of any party to sue for any breach by any other party (or parties).

 

5.2           Fees
and Expenses. At the Closing, the Company has agreed to reimburse Alpha Capital Anstalt the non-accountable sum of $25,000

payments, the aggregate amount that Alpha is to pay for the Securities at the Closing shall be reduced by $25,000 in lieu thereof.
Except as expressly set forth in the Transaction Documents to the contrary, each party shall pay the fees and expenses of its advisers,
counsel, accountants and other experts, if any, and all other expenses incurred by such party incident to the negotiation, preparation,

any fees required for same-day processing of any instruction letter delivered by the Company and any conversion or exercise notice
delivered by a Purchaser), stamp taxes and other taxes and duties levied in connection with the delivery of any Securities to the
Purchasers.

in the case of an amendment, by the Company and the Purchasers holding at least 67% in interest of the Securities then outstanding
or, in the case of a waiver, by the party against whom enforcement of any such waived provision is sought. No waiver of any default
with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future
or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay
or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right.

Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors
and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except as otherwise
set forth in Section 4.10.

 

5.9           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 New York, 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, partners, members, employees or agents) shall be commenced
exclusively in the state and federal courts sitting in the City of New York. Each party hereby irrevocably submits to the exclusive
jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan for the adjudication of any
dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect
to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any action,
suit or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or
proceeding is improper or is an inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of
process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or
certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under
this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing
contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law. If either
party shall commence an action or proceeding to enforce any provisions of the Transaction Documents, then, in addition to the obligations
of the Company under Section 4.10, the prevailing party in such action, suit or proceeding shall be reimbursed by the other party
for its reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution
of such action or proceeding.

 

5.10           Survival.
The representations and warranties contained herein shall survive the Closing and the delivery of the Securities.

 

5.11           Execution.
This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same
agreement and shall become effective when counterparts have been signed by each party and delivered to each other party, it being
understood that the parties need not sign the same counterpart. 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.

 

    	36

    	 

    

 

5.12           Severability.
If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal,
void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full
force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially
reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated
by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that
they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be
hereafter declared invalid, illegal, void or unenforceable.

 

5.13           Rescission
and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of)
any of the other Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction
Document and the Company does not timely perform its related obligations within the periods therein provided, then such Purchaser
may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand
or election in whole or in part without prejudice to its future actions and rights; provided, however, that in the
case of a rescission of a conversion of the Preferred Stock or exercise of a Warrant, the applicable Purchaser shall be required
to return any shares of Common Stock subject to any such rescinded conversion or exercise notice concurrently with the return to
such Purchaser of the aggregate exercise price paid to the Company for such shares and the restoration of such Purchaser’s
right to acquire such shares pursuant to such Purchaser’s Warrant (including, issuance of a replacement warrant certificate
evidencing such restored right).

 

5.14           Replacement
of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company
shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), 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. The applicant for a new certificate or instrument under such circumstances shall
also pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement Securities.

 

5.15           Remedies.
In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of
the Purchasers and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that
monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the
Transaction Documents and hereby agree to waive and not to assert in any action for specific performance of any such obligation
the defense that a remedy at law would be adequate.

 

5.16           Payment
Set Aside. To the extent that the Company makes a payment or payments to any Purchaser pursuant to any Transaction Document
or a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or
exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from,
disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person
under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action),
then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived
and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

 

    	37

    	 

    

 

5.17           Usury.
To the extent it may lawfully do so, the Company hereby agrees not to insist upon or plead or in any manner whatsoever claim, and
will resist any and all efforts to be compelled to take the benefit or advantage of, usury laws wherever enacted, now or at any
time hereafter in force, in connection with any claim, action or proceeding that may be brought by any Purchaser in order to enforce
any right or remedy under any Transaction Document. Notwithstanding any provision to the contrary contained in any Transaction
Document, it is expressly agreed and provided that the total liability of the Company under the Transaction Documents for payments
in the nature of interest shall not exceed the maximum lawful rate authorized under applicable law (the “Maximum Rate”),
and, without limiting the foregoing, in no event shall any rate of interest or default interest, or both of them, when aggregated
with any other sums in the nature of interest that the Company may be obligated to pay under the Transaction Documents exceed such
Maximum Rate. It is agreed that if the maximum contract rate of interest allowed by law and applicable to the Transaction Documents
is increased or decreased by statute or any official governmental action subsequent to the date hereof, the new maximum contract
rate of interest allowed by law will be the Maximum Rate applicable to the Transaction Documents from the Closing Date thereof
forward, unless such application is precluded by applicable law. If under any circumstances whatsoever, interest in excess of the
Maximum Rate is paid by the Company to any Purchaser with respect to indebtedness evidenced by the Transaction Documents, such
excess shall be applied by such Purchaser to the unpaid principal balance of any such indebtedness or be refunded to the Company,
the manner of handling such excess to be at such Purchaser’s election.

 

5.18           Independent
Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several
and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance
or non-performance of the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any
other Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the
Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers
are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction
Documents. Each Purchaser shall be entitled to independently protect and enforce its rights, including, without limitation, the
rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser
to be joined as an additional party in any proceeding for such purpose. Each Purchaser has been represented by its own separate
legal counsel in its review and negotiation of the Transaction Documents. For reasons of administrative convenience only, each
Purchaser and its respective counsel have chosen to communicate with the Company through EGS. EGS does not represent any of the
Purchasers and only represents Alpha. The Company has elected to provide all Purchasers with the same terms and Transaction Documents
for the convenience of the Company and not because it was required or requested to do so by any of the Purchasers. It is expressly
understood and agreed that each provision contained in this Agreement and in each other Transaction Document is between the Company
and a Purchaser, solely, and not between the Company and the Purchasers collectively and not between and among the Purchasers.

5.19           Liquidated
Damages. The Company’s obligations to pay any partial liquidated damages or other amounts owing under the Transaction
Documents is a continuing obligation of the Company and shall not terminate until all unpaid partial liquidated damages and other
amounts have been paid notwithstanding the fact that the instrument or security pursuant to which such partial liquidated damages
or other amounts are due and payable shall have been canceled.

 

5.20           Saturdays,
Sundays, Holidays, etc.If the last or appointed day for the taking of any action or the expiration of any right required
or granted herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding
Business Day.

 

5.21           Construction.
The parties agree that each of them and/or their respective counsel have reviewed and had an opportunity to revise the Transaction
Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting
party shall not be employed in the interpretation of the Transaction Documents or any amendments thereto. In addition, each and
every reference to share prices and shares of Common Stock in any Transaction Document shall be subject to adjustment for reverse
and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock that occur after
the date of this Agreement.

 

5.22           WAIVER
OF JURY TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY, THE PARTIES
EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY, UNCONDITIONALLY, IRREVOCABLY
AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY.
