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)

Transaction Documents, will be duly and validly issued, fully paid and nonassessable, free and clear of all Liens imposed by the

the Securities Act, which became effective on June 14, 2013 (the “Effective Date”), including the Prospectus,
and such amendments and supplements thereto as may have been required to the date of this Agreement. The Registration Statement
is effective under the Securities Act and no stop order preventing or suspending the effectiveness of the Registration Statement
or suspending or preventing the use of the Prospectus has been issued by the Commission and no proceedings for that purpose have
been instituted or, to the knowledge of the Company, are threatened by the Commission. The Company, if required by the rules and
regulations of the Commission, shall file the Prospectus with the Commission pursuant to Rule 424(b). At the time the Registration
Statement and any amendments thereto became effective, at the date of this Agreement and at the Closing Date, the Registration

The capitalization of the Company is as set forth in the SEC Reports. The Company has not issued any capital stock since its most

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 set

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. Except as set forth in
the Disclosure Schedules, the issuance and sale of the Shares 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 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, except as otherwise disclosed on Schedule 3.1(h). The authorized shares
of the Company conform in all material respects to all statements relating thereto contained in the Registration Statement, the
Base Prospectus and the Prospectus Supplement. The offers and sales of the Company’s securities were at all relevant times
either registered under the Securities Act and the applicable state securities or Blue Sky laws or, based in part on the representations
and warranties of the purchasers, exempt from such registration requirements. No further approval or authorization of any stockholder,
the Board of Directors or others is required for the issuance and sale of the Shares. 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.

enforceability of any of the Transaction Documents or the Shares or (ii) could, if there were an unfavorable decision, have or
reasonably be expected to result in a Material Adverse Effect. Neither the Company nor any Subsidiary, nor any current 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

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,

as amended, including the regulations and published interpretations thereunder (“ERISA”), or
Section 4975 of the Internal Revenue Code of 1986, as amended from time to time (the “Code”)) or
“accumulated funding deficiency” (as defined in Section 302 of ERISA) or any of the events set forth in Section 4043(b)

transportation, handling, treatment, disposal, discharge, emission, or other release of any kind of toxic or other wastes or other
hazardous substances regulated by Environmental Laws (“Hazardous Substances”) by

for whose acts or omissions the Company or any Subsidiary is or may otherwise be liable) upon any of the property now
or previously owned or leased by the Company or any Subsidiary, or upon any other property, in violation of any law, statute,
ordinance, rule, regulation, order, judgment, decree or permit or which would, under any law, statute, ordinance, rule (including

now leased by the Company or any Subsidiary or into the environment surrounding such property of any Hazardous Substance,
except for any such disposal, discharge, emission, or other release in violation of Environmental Laws which could not reasonably

(r)           Insurance.
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. 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.


 


(s)          Transactions

or any such employee has a substantial interest or is an officer, director, trustee, stockholder, member or partner, in each case
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

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. Except as set forth in the SEC Reports, the Company and the

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.

by the Company, any Subsidiary or Affiliate of the Company to any broker, financial advisor or consultant, finder, placement agent,
investment banker, bank or other Person with respect to the transactions contemplated by the Transaction Documents. To the Company’s
knowledge, there are no other arrangements, agreements or understandings of the Company or, to the Company’s knowledge, any
of its stockholders that may affect the Purchasers’ compensation, as determined by FINRA. The Company has not made any direct

in consideration of such person raising capital for the Company or introducing to the Company persons who raised or provided capital

or be an Affiliate of, an “investment company” within the meaning of the Investment Company Act of 1940, as 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.


 


(w)         Registration
Rights. No Person has any right to cause the Company or any Subsidiary to effect the registration under the Securities Act
of any securities of the Company or any Subsidiary.


 


(x)          Listing
and Maintenance Requirements. The Shares are registered pursuant to Section 12(b) of the Exchange Act, and the Company has
taken no action designed to, or which to its knowledge is likely to have the effect of, terminating the registration of the Shares
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 Shares are
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. Except as set forth in the Prospectus Supplement or the SEC Reports, 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.

corporation and the Company is current in payment of the fees to the Depository Trust Company (or such other established clearing
corporation) in connection with such electronic transfer.

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)

(z)          Disclosure;
10b-5. 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 which is not
otherwise disclosed in the Prospectus Supplement. The Company understands and confirms that the Purchasers will rely on the foregoing
representation in effecting transactions in securities of the Company. The Registration Statement (and any further documents to
be filed with the Commission incorporated into the Registration Statement) contains all exhibits and schedules as required by the
Securities Act. Each of the Registration Statement and any post-effective amendment thereto, if any, at the time it became effective,
complied in all material respects with the Securities Act and the Exchange Act and the applicable rules and regulations under the
Securities Act and did not and, as amended or supplemented, if applicable, will not, contain any untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary to make the statements therein in light of the
circumstances under which they were made not misleading. The Base Prospectus and the Prospectus Supplement, each as of its respective
date, comply in all material respects with the Securities Act and the Exchange Act and the applicable rules and regulations promulgated
thereunder. Each of the Base Prospectus and the Prospectus Supplement, as amended or supplemented, did not and will not contain
as of the date thereof any untrue statement of a material fact or omit to state a material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made, not misleading. The SEC Reports, when they were filed
with the Commission, conformed in all material respects to the requirements of the Exchange Act and the applicable rules and regulations
promulgated thereunder, and none of such documents, when they were filed with the Commission, contained any untrue statement of
a material fact or omitted to state a material fact necessary to make the statements therein (with respect to the SEC Reports incorporated
by reference in the Base Prospectus or Prospectus Supplement), in light of the circumstances under which they were made not misleading;
and any further documents so filed and incorporated by reference in the Base Prospectus or Prospectus Supplement, when such documents
are filed with the Commission, will conform in all material respects to the requirements of the Exchange Act and the applicable
rules and regulations, as applicable, and will not contain any untrue statement of a material fact or omit to state a material
fact necessary to make the statements therein, in light of the circumstances under which they were made not misleading. No post-effective
amendment to the Registration Statement reflecting any facts or events arising after the date thereof which represent, individually
or in the aggregate, a fundamental change in the information set forth therein is required to be filed with the Commission. There
are no documents required to be filed with the Commission in connection with the transaction contemplated hereby that (x) have
not been filed as required pursuant to the Securities Act or (y) will not be filed within the requisite time period. There are
no contracts or other documents required to be described in the Base Prospectus or Prospectus Supplement, or to be filed as exhibits
or schedules to the Registration Statement, which have not been described, incorporated by reference or filed as required. The
press releases disseminated by the Company during the twelve months preceding the date of this Agreement taken as a whole do 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.

(aa)        No
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 Shares to be integrated with prior offerings by the Company for purposes of any applicable shareholder approval provisions
of any Trading Market on which any of the securities of the Company are listed or designated.


 


(bb)       Solvency.
Based on the consolidated financial condition of the Company as of the Closing Date, after giving effect to the receipt by the
Company of the proceeds from the sale of the Shares 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. The SEC Reports set 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 $50,000 (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 $50,000 due under leases required
to be capitalized in accordance with GAAP.

(cc)        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. The provisions for taxes payable, if any, shown on the financial statements
filed with or as part of the Registration Statement are sufficient for all accrued and unpaid taxes, whether or not disputed, and
for all periods to and including the dates of such consolidated financial statements. The term “taxes” mean all federal,
state, local, foreign, and other net income, gross income, gross receipts, sales, use, ad valorem, transfer, franchise, profits,
license, lease, service, service use, withholding, payroll, employment, excise, severance, stamp, occupation, premium, property,
windfall profits, customs, duties or other taxes, fees, assessments, or charges of any kind whatsoever, together with any interest
and any penalties, additions to tax, or additional amounts with respect thereto. The term “returns” means all returns,
declarations, reports, statements, and other documents required to be filed in respect to taxes. The Company and each Subsidiary has
not engaged in any transaction which is a corporate tax shelter or which could be characterized as such by the Internal Revenue
Service or any other taxing authority.  The accruals and reserves on the books and records of the Company in respect
of tax liabilities for any taxable period not yet finally determined are adequate to meet any assessments and related liabilities
for any such period, and since the date of the most recent audited financial statements included in the SEC Reports, the Company
and each Subsidiary has not incurred any liability for taxes other than in the ordinary course.


 


(dd)       Foreign
Corrupt Practices. Neither the Company nor any Subsidiary, nor to the knowledge of the Company or any Subsidiary, any agent
or other person acting on behalf of the Company or any Subsidiary, has (i) directly or indirectly, used any funds for unlawful
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. The Company has taken reasonable steps to ensure that its accounting controls and procedures are sufficient
to cause the Company to comply in all material respects with the FCPA.


 


(ee)       Accountants.
To the knowledge and belief of the Company, the Company Auditor (i) is an independent registered public accounting firm as required
by the Exchange Act and (ii) has expressed its opinion with respect to the financial statements to be included in the Company’s
Annual Report for the fiscal year ended June 30, 2013. The Company Auditor has not, during the periods covered by the financial
statements included in the Base Prospectus or Prospectus Supplement, provided to the Company any non-audit services, as such term
is used in Section 10A(g) of the Exchange Act.

Food, Drug and Cosmetic Act, as amended, and the regulations thereunder (“FDCA”) that is manufactured, packaged,
labeled, tested, distributed, sold, and/or marketed by the Company or any of its Subsidiaries (each such product, a “Product”),
such Product is being manufactured, packaged, labeled, tested, distributed, sold and/or marketed by the Company in compliance with
all applicable requirements under FDCA and similar laws, rules and regulations, except where the failure to be in compliance would
not have a Material Adverse Effect.  There is no pending, completed or, to the Company's knowledge, threatened, action (including
any lawsuit, arbitration, or legal or administrative or regulatory proceeding, charge, complaint, or investigation) against the
Company or any of its Subsidiaries, and none of the Company or any of its Subsidiaries has received any notice, warning letter
or other communication from the FDA or any other governmental entity, which (i) contests the approval of, the uses of, the distribution
of, the manufacturing or packaging of, the sale of, or the labeling and promotion of any Product, (ii) withdraws its approval of,

violation of any laws, rules or regulations by the Company or any of its Subsidiaries, and which, either individually or in the
aggregate, would have a Material Adverse Effect.  The properties, business and operations of the Company have been and are
being conducted in all material respects in accordance with all applicable laws, rules and regulations of the FDA.  The Company
has not been informed by the FDA that the FDA will prohibit the marketing, sale, license or use in the United States of any product

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 this Agreement and otherwise
to carry out its obligations hereunder and thereunder. The execution and delivery of this Agreement and performance by such Purchaser
of the transactions contemplated by this Agreement 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 is acquiring the Securities as principal for its own account and has no direct or indirect
arrangement or understandings with any other persons to distribute or regarding the distribution of such Securities (this representation
and warranty not limiting such Purchaser’s right to sell the Securities pursuant to the 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 Shares, it was, and as of the date hereof it is an “accredited investor”
as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the Securities Act.


 


(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 Shares, 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 Shares and, at the present time, is able to afford a complete loss of such investment.


 


(e)          Access
to Information. Such Purchaser acknowledges that it has had the opportunity to review the Transaction Documents (including
all exhibits and schedules thereto) and the SEC Reports and has been afforded (i) the opportunity to ask such questions as it has
deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering
of the Shares and the merits and risks of investing in the Shares; (ii) access to information about the Company and its financial
condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment;
and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable
effort or expense that is necessary to make an informed investment decision with respect to the investment.  Such Purchaser
acknowledges and agrees that neither the Placement Agent nor any Affiliate of the Placement Agent has provided such Purchaser with
any information or advice with respect to the Securities nor is such information or advice necessary or desired.  Neither
the Placement Agent nor any Affiliate has made or makes any representation as to the Company or the quality of the Securities and
the Placement Agent and any Affiliate may have acquired non-public information with respect to the Company which such Purchaser
agrees will not be provided to it.  In connection with the issuance of the Securities to such Purchaser, neither the
Placement Agent nor any of its Affiliates has acted as a financial advisor or fiduciary to such Purchaser.


 




    	25



    	 



    

 


(f)          Certain
Transactions and Confidentiality. Other than consummating the transactions contemplated hereunder, such Purchaser has not,
nor has any Person acting on behalf of or pursuant to any understanding with such Purchaser, directly or indirectly 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 pricing 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 Shares 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.

in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Shares for purposes of the rules and

Trading Market regulations, in which case the Company shall provide the Purchasers with prior notice of such disclosure permitted
under this clause (b).


 


4.4         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 Shares
under the Transaction Documents or under any other agreement between the Company and the Purchasers.


 


4.5         Non-Public
Information. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents,

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.

4.6         Use
of Proceeds. The Company shall use the net proceeds from the sale of the Shares hereunder for working capital purposes and

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.

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,

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 a Purchaser
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 any of the representations, warranties, covenants or agreements made by
such Purchaser Party in this Agreement or in the other Transaction Documents. The indemnification required by this Section 4.7
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.

application all of the Shares, and will take such other action as is necessary to cause all of the Shares to be listed or quoted
on such other Trading Market as promptly as possible. The Company will then take all action reasonably necessary to continue the
listing and trading of its Common Stock on a Trading Market and will comply in all respects with the Company’s reporting,
filing and other obligations under the bylaws or rules of the Trading Market. The Company agrees to maintain the eligibility of
the Common Stock for electronic transfer through the Depository Trust Company or another established clearing corporation, including,
without limitation, by timely payment of fees to the Depository Trust Company or such other established clearing corporation in
connection with such electronic transfer.


 


4.9         [RESERVED]


 


4.10       Subsequent
Equity Sales.


 


(a)          From
the date hereof until 75 days after the Closing Date, 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 75 days after the Closing Date, 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 (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 issue 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.


 




    	29



    	 



    

 


(c)          Notwithstanding
the foregoing, this Section 4.10 shall not apply in respect of an Exempt Issuance, except that no Variable Rate Transaction shall
be an Exempt Issuance.


 


4.11       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 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 Shares or otherwise.


 


4.12       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 4.3.  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 4.3, such Purchaser will maintain the confidentiality of the existence and terms of this transaction and
the information included in 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 4.3, (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 4.3 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
4.3.  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 Shares covered by this Agreement.

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.


 


5.6         Headings.
The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect
any of the provisions hereof.


 


5.7         Successors
and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted
assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of
each Purchaser (other than by merger). Any Purchaser may assign any or all of its rights under this Agreement to any Person to
whom such Purchaser assigns or transfers any Shares, provided that such transferee agrees in writing to be bound, with respect
to the transferred Shares, by the provisions of the Transaction Documents that apply to the “Purchasers.”

5.8         No
Third-Party Beneficiaries. The Placement Agent shall be the third party beneficiary of the representations and warranties of
the Company in Section 3.1 and the representations and warranties of the Purchasers in Section 3.2. 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 4.7 and this Section 5.8.


 


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 suit, action
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, suit or proceeding to enforce any provisions of the Transaction Documents, then, in addition to the obligations of the
Company under Section 4.7, 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 Shares.


 


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.

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.


 


5.14       Replacement
of Shares. If any certificate or instrument evidencing any Shares is mutilated, lost, stolen or destroyed, the Company shall
issue or cause to be issued in exchange and substitution for and upon cancellation thereof (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 Shares.


 


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.

5.17       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 the Placement Agent. 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.


 


5.18       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.


 


5.19       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.


 


5.20       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.
