    WHEREAS, Borrower has requested that

    NOW,
THEREFORE, FOR MUTUAL CONSIDERATIONS, the receipt and sufficiency of which is
hereby acknowledged, the undersigned Borrower and Lender do hereby modify the
Loan Documents as follows:

    

    1) Capitalized
Terms.  Any capitalized term used but not defined herein shall
have the meaning ascribed to it in the Loan Documents.  All references
to the “Loan Documents” in the Loan Agreement and any of the other Loan
Documents shall include, without limitation, this Agreement and all other such
Loan Documents, as modified by this Agreement.

     

    
      
        
        

      

      
        1

        
          

        

      

      
        
        

      

    

     

    2) Extension of Maturity Date;
Waiver. Subject to Borrower’s compliance with all representations,
warranties, covenants and agreements contained in this Agreement and all the
other Loan Documents as modified hereby:

     

    (a) Maturity
Date.  The “Maturity Date” set forth in the Loan Agreement and
elsewhere in the Loan Documents is hereby modified to mean August 29, 2008 (the
“New Maturity
Date”).

     

    (b) Waivers.  Lender
hereby extends the Waivers for a period through and including the New Maturity
Date.

     

    3) Modification of the
Note.  The Note and, where applicable, the other Loan Documents
are hereby modified as follows:

     

    a. Interest
Rate.  From and after June 30, 2008 through and including the
New Maturity Date, interest shall accrue on the outstanding principal balance of
the Note at a fixed annual rate equal to the LIBOR Rate, as hereinafter defined,
plus three hundred fifty (350) basis points (LIBOR Rate + 3.50%). As used
herein, the term "LIBOR Rate" refers to the sixty (60) day London Interbank
Offered Rate, as determined by Lender in its sole (but reasonable)
discretion.  The LIBOR Rate shall be determined by Lender as of June
30, 2008 (or, if such date is not a business day, then on the next preceding
business day).  Interest shall be calculated on the basis of a 360 day
year and the actual number of calendar days elapsed.  Notwithstanding
anything else in this instrument to the contrary, in no event shall the maximum
rate of interest payable in respect to the indebtedness evidenced hereby exceed
the maximum rate of interest allowed to be charged by applicable
law.

     

    b. Payment
Schedule.  Said principal and accrued interest thereon shall be
due and payable as hereinafter set forth:

     

    i) Concurrently
with Borrower’s execution hereof, Borrower shall pay to Lender:

     

    (1) all
accrued and unpaid interest due on the Loan through and including June 30, 2008,
in the amount of Eight Hundred Twenty Eight Thousand Four Hundred Thirty Two
Dollars and 72/100 ($828,432.72); and

     

    (2) Four
Hundred Ninety Five Thousand One Hundred Seventy Five Dollars and 63/100
($495,175.63) as prepayment of (and to be credited against) interest on the Loan
at the aforesaid rate, as and when such interest accrues, for the period
beginning July 1, 2008; provided, that if a Termination Event, defined below,
occurs prior to the New Maturity Date, then any portion of such prepayment that
remains uncredited at the time of such Termination Event shall, at Lender’s sole
option, be applied to the outstanding principal balance of the
Loan.

     

    
      
        
        

      

      
        2

        
          

        

      

      
        
        

      

    

     

    ii) On the
New Maturity Date the entire outstanding principal balance of the Loan, any
accrued and unpaid interest thereon, and all incurred fees shall be due and
payable without demand.

     

    c. No New
Advances.  Borrower may not reborrow any sums repaid under the
Loan, and Lender has no obligation to advance any new loan proceeds under the
Loan.

     

    4) Conditions of Extension of
Maturity Date;
Waiver. Lender’s agreement to extend the Maturity Date and Waivers
is conditioned upon and subject to the timely satisfaction by Borrower of each
of the following conditions (collectively the “Conditions of
Modification”):

     

    a. Correctness and
Warranties.  Except as expressly modified or waived herein, all
representations and warranties made by Borrower to Lender under this Agreement
and the other Loan Documents (including without limitation all of Borrower’s
representations and warranties set forth in Sections 3.5 and 3.9 of the Loan
Agreement) are and shall remain true and correct through and including the New
Maturity Date and payment in full of the Loan.

     

    b. No Defaults
Hereunder.  Borrower shall not breach any promise or covenant
contained in this Agreement and shall not be in default under any provision
of this Agreement or the other Loan Documents (except with respect to the
Waivers, as waived hereby).

     

    5) Termination
Events.  Each of the following shall constitute a Termination
Event and an Event of Default under this Agreement and all other Loan Documents
without any further cure or grace period, notwithstanding anything to the
contrary in the Loan Documents (each, a “Termination
Event”):

     

    a. Conditions of Modification;
Compliance.  If Borrower shall fail to comply in a timely
manner with any of the Conditions of Modification set forth above.

     

    b. Bankruptcy. If
Borrower shall become a debtor in bankruptcy by means of either a voluntary or
involuntary petition.

     

    c. Receivership;
Insolvency.  If any kind of receivership or insolvency
proceeding is commenced by or against Borrower.

     

    6) New Maturity Date;
Acceleration of Loan.  Borrower agrees that the Loan
automatically, and without notice, shall be immediately all due and payable in
full upon the earlier of:

     

    a. New
Maturity Date; or

     

    b. The
occurrence of any Termination Event, as defined above.

     

    The entire amount of the Loan,
including all accrued and unpaid interest, shall be immediately due and payable
upon the earlier to occur of the New Maturity Date or the occurrence of any
Termination Event, and Lender shall be entitled immediately to exercise all of
its rights and remedies under the Loan Documents, all without further notice to
Borrower.

     

    
      
        
        

      

      
        3

        
          

        

      

      
        
        

      

    

     

    7) Representations, Warranties
and Covenants.  As an inducement to Lender to enter into this
Agreement, Borrower makes the following representations, warranties and
covenants:

     

    a. Enforceability.  The
Loan, this Agreement, and all the other Loan Documents are fully
enforceable, and the Loan is not subject to any defense or counterclaim or any
claim of setoff or recoupment by Borrower.

     

    b. Representation by
Counsel. Borrower has been represented by, or advised to consult
with, counsel in connection with the negotiation and execution of this
Agreement; this Agreement represents an arms-length transaction; and Borrower
has acted in good faith in the making of this Agreement.

     

    c. Consents. The
execution and performance of this Agreement by Borrower does not and will not
violate any agreement to which Borrower is a party, and the execution and
performance of this Agreement by Borrower does not require the consent of any
third party, or if the consent of a third party is required, such consent has
been previously obtained by Borrower.

     

    d. Sale of
Assets.  Through and including the New Maturity Date, Borrower
will not dispose of any of its property outside the ordinary course of business
or as otherwise provided for in this Agreement.

     

    e. New
Debt.  Through and including the New Maturity Date, Borrower
will not incur any additional debt except for unsecured trade debt incurred in
the ordinary course of business without the prior written consent of Lender in
its sole and absolute discretion.

     

    f. Impairment.  Borrower
will take no action which would impair its ability to perform its obligations
hereunder or to satisfy any of the Conditions of Modification.

     

    g. Extension
Fee. Concurrently with Borrower’s execution hereof, Borrower shall
pay (i) Lender a fee of one-quarter of one percent (1/4%) of the current
outstanding $48,300,000.00 principal balance of the loan, or $120,750.00, and
(ii) Lender’s attorneys fees in connection herewith in the amount of
$3,500.00.

     

    8) Further
Assurances.  At any time and from time to time after the date
of this Agreement, at the request of Lender, Borrower shall, without further
consideration, and at Borrower’s sole expense, execute and deliver such
documents and instruments, and take such actions, as Lender may deem necessary
(a) to perfect any of Lender’s security interests or liens granted in any of the
Loan Documents, and/or (b) to carry out the purposes and intentions of this
Agreement and the Loan Documents.

     

    9) Effectiveness of the
Loan.  This Agreement shall not constitute a novation of any of
the other Loan Documents, and all the Loan Documents shall survive the execution
of this Agreement and remain in full force and effect subject only to the
Waivers as set forth herein and to any express modifications thereto as herein
provided.  The lien and security interest on the Collateral granted
pursuant to the Pledge is hereby extended, and the lien and security interest on
the Collateral shall continue to secure the remaining amounts outstanding in
respect of all indebtedness that may be due and owing pursuant to the terms of
the Loan Documents, including without limitation principal and interest on all
amounts loaned pursuant to the Note. There are no oral representations or
assurances from Lender to Borrower which survive the execution of this
Agreement.

    10) Release and
Waiver.  Borrower hereby acknowledges and stipulates that it
has no claims or causes of action of any kind whatsoever against
Lender.  Borrower represents that it is entering into this Agreement
freely, and with the advice of counsel as to its legal
alternatives.  Borrower hereby releases Lender from any and all
claims, causes of action, demands and liabilities of any kind whatsoever whether
direct or indirect, fixed or contingent, liquidated or unliquidated, disputed or
undisputed, known or unknown, which Borrower has or may acquire in the future
relating in any way to any event, circumstance, action or failure to act to the
date of this Agreement.  The release by Borrower herein, together with
the other terms and provisions of this Agreement, is executed by Borrower
advisedly and without coercion or duress from Lender, Borrower having determined
that the execution of this Agreement, and all its terms and provisions are in
Borrower's economic best interest.

     

    11) No Obligation to Extend; No
Waiver.  Borrower acknowledges and agrees that Lender is not
obligated and does not agree to any additional extensions of the New Maturity
Date or any further Waivers except as expressly set forth
herein.  Except as expressly provided herein as to the New Maturity
Date and the Waivers, (i) this Agreement shall not constitute a waiver by Lender
of any defaults under the Loan Documents, (ii) Lender reserves all of its rights
and remedies under the other Loan Documents, and (iii) all of the Loan Documents

or delay by Lender with respect to exercising any right, power or privilege of
Lender under the Loan Documents or this Agreement, shall operate as a waiver
thereof, except to the extent expressly provided herein.

CERTIFICATE OF DESIGNATION OF THE RELATIVE RIGHTS AND

PREFERENCES

OF THE

SERIES A CONVERTIBLE PREFERRED STOCK

OF

DENTALSERV.COM

     The undersigned, the Chief Executive Officer of Dentalserv.com, a Nevada corporation (the “Company”), in accordance with the provisions of the Nevada Revised Statutes, does hereby certify that, pursuant to the
authority conferred upon the Board of Directors by the Articles of Incorporation of the Company, the following resolution creating a series of preferred stock, designated as Series A Convertible Preferred Stock, was duly adopted on September 5,
2007, as follows:

     RESOLVED, that pursuant to the authority expressly granted to and vested in the Board of Directors of the Company by provisions of the Articles of Incorporation of the Company (the “Articles of
Incorporation”), there hereby is created out of the shares of the Company’s preferred stock, par value $0.01 per share, of the Company authorized in Article VI of the Articles of Incorporation (the “Preferred Stock”), a
series of Preferred Stock of the Company, to be named “Series A Convertible Preferred Stock,” consisting of 6,668,230 shares, which series shall have the following designations, powers, preferences and relative and other special rights and
the following qualifications, limitations and restrictions:

     1. Designation and Rank. The designation of such series of the Preferred Stock shall be the Series A Convertible Preferred Stock, par value $0.01 per share (the “Series A Preferred Stock”). The
maximum number of shares of Series A Preferred Stock is 6,668,230 shares. The Series A Preferred Stock shall rank senior to the Company’s common stock, par value $0.01 per share (the “Common Stock”), and to all other classes and
series of equity securities of the Company which by their terms do not rank senior to the Series A Preferred Stock (“Junior Stock”). The Series A Preferred Stock shall be subordinate to and rank junior to all indebtedness of the Company
now or hereafter outstanding.

     2. Dividends.

          (a) Payment of Dividends. Commencing on the date of the initial issuance (the “Issuance Date”) of the Series A Preferred Stock, the holders of record of shares of Series A Preferred Stock shall be
entitled to receive, out of any assets at the time legally available therefor and as declared by the Board of Directors, cash dividends at the rate of five percent (5%) of the stated Liquidation Preference Amount (as defined in Section 4 hereof) per
share per annum (the “Dividend Payment”), and no more, payable on the date of payment of the Liquidation Preference Amount to the holders of Series A Preferred Stock, pursuant to Section 4 hereof, in the event of a dissolution, liquidation
or winding up of the Company. In the case of shares of Series A Preferred Stock outstanding for less than a full year, dividends shall be pro rated based on the portion of each year during which such shares are outstanding. Dividends on the Series A
Preferred Stock shall be cumulative, shall accrue and be payable in the event of a dissolution, liquidation or winding up of the Company pursuant to Section 4 hereof. Dividends on the Series

A Preferred Stock are prior and in preference to any declaration or payment of any distribution (as defined below) on any outstanding shares of Junior Stock. Such dividends shall accrue on each share of Series A Preferred Stock from day to day
whether or not earned or declared so that if such dividends with respect to any previous dividend period at the rate provided for herein have not been paid on, or declared and set apart for, all shares of Series A Preferred Stock at the time
outstanding, the deficiency shall be fully paid on, or declared and set apart for, such shares on a pro rata basis with all other equity securities of the Company ranking pari passu with the Series A Preferred Stock as to the payment of dividends
before any distribution shall be paid on, or declared and set apart for Junior Stock.

          (b) So long as any shares of Series A Preferred Stock are outstanding, the Company shall not declare, pay or set apart for payment any dividend or make any distribution on any Junior Stock (other than dividends or
distributions payable in additional shares of Junior Stock), unless at the time of such dividend or distribution the Company shall have paid all accrued and unpaid dividends on the outstanding shares of Series A Preferred Stock,

          (c) In the event of (i) a mandatory redemption pursuant to Section 9 hereof or (ii) a redemption upon the occurrence of a Major Transaction (as defined in Section 8(c) hereof) or a ‘triggering Event (as defined in
Section 8(d) hereof), all accrued and unpaid dividends on the Series A Preferred Stock shall be payable on the date of such redemption. In the event of a conversion pursuant to Section 5(a) hereof, all accrued and unpaid dividends on the Series A
Preferred Stock being converted shall be payable on the Conversion Date (as defined in Section 5(b)(i) hereof).

          (d) For purposes hereof, unless the context otherwise requires, “distribution” shall mean the transfer of cash or property without consideration, whether by way of dividend or otherwise, payable other than in
shares of Common Stock or other equity securities of the Company, or the purchase or redemption of shares of the Company (other than redemptions set forth in Section 8 below or repurchases of Common Stock held by employees or consultants of the
Company upon termination of their employment or services pursuant to agreements providing for such repurchase or upon the cashless exercise of options held by employees or consultants) for cash or property.

     3. Voting Rights.

          (a) Class Voting Rights. So long as the shares of Preferred Stock outstanding shall equal at least two hundred thousand (200,000), the Company shall not, without the affirmative vote or consent of the holders of
at least seventy-five percent (75%) of the shares of the Series A Preferred Stock outstanding at the time, given in person or by proxy, either in writing or at a meeting, in which the holders of the Series A Preferred Stock vote separately as a
class: (i) authorize, create, issue or increase the authorized or issued amount of any class or series of stock ranking pari passu or senior to the Series A Preferred Stock, with respect to the distribution of assets on liquidation, dissolution or
winding up; (ii) amend, alter or repeal the provisions of the Series A Preferred Stock, whether by merger, consolidation or otherwise, so as to adversely affect any right, preference, privilege or voting power of the Series A Preferred Stock;
provided, however, that any creation and issuance of another series of Junior Stock shall not be deemed to adversely affect such rights, preferences, privileges or voting powers; (iii)

4

repurchase, redeem or pay dividends on, shares of Common Stock or any other shares of the Company’s Junior Stock (other than de minimus repurchases from employees of the Company in certain circumstances, and any contractual redemption
obligations existing as of the date hereof as disclosed in the Company’s public filings with the Securities and Exchange Commission); (iv) amend the Articles of Incorporation or By-Laws of the Company so as to affect materially and adversely
any right, preference, privilege or voting power of the Series A Preferred Stock; provided, however, that any creation and issuance of another series of Junior Stock shall not be deemed to adversely affect such rights, preferences, privileges
or voting powers; (v) effect any distribution with respect to Junior Stock other than as permitted hereby; (vi) reclassify the Company’s outstanding securities in a way that adversely affects the rights, preferences, privileges or voting powers
of the Preferred Stock; (vii) voluntarily file for bankruptcy, liquidate the Company’s assets or make an assignment for the benefit of the Company’s creditors; or (viii) no longer are involved in the business of commercializing medical
devices,

          (b) General Voting Rights. Except with respect to transactions upon which the Series A Preferred Stock shall be entitled to vote separately as a class pursuant to Section 3(a) above and except as otherwise
required by Nevada law, the Series A Preferred Stock shall have no voting rights. The Common Stock into which the Series A Preferred Stock is convertible shall, upon issuance, have all of the same voting rights as other issued and outstanding Common
Stock of the Company, and none of the rights of the Preferred Stock.

     4. Liquidation Preference.

          (a) In the event of the liquidation, dissolution or winding up of the affairs of the Company, whether voluntary or involuntary, the holders of shares of Series A Preferred Stock that are outstanding shall be entitled to
receive, out of the assets of the Company available for distribution to its stockholders, an amount equal to $1.81 per share (the “Liquidation Preference Amount”) of the Series A Preferred Stock plus any accrued and unpaid Dividend
Payments, to be paid as an accreting liquidation preference, before any payment shall be made or any assets distributed to the holders of the Common Stock or any other Junior Stock. If the assets of the Company are not sufficient to pay in full the
Liquidation Preference Amount plus any accrued and unpaid dividends payable to the holders of outstanding shares of the Series A Preferred Stock and any series of Preferred Stock or any other class of stock ranking pari passu, as to rights on
liquidation, dissolution or winding up, with the Series A Preferred Stock, then all of said assets will be distributed among the holders of the Series A Preferred Stock and the other classes of stock ranking pari passu with the Series A Preferred
Stock, if any, ratably in accordance with the respective amounts that would be payable on such shares if all amounts payable thereon were paid in full. The liquidation payment with respect to each outstanding fractional share of Series A Preferred
Stock shall be equal to a ratably proportionate amount of the liquidation payment with respect to each outstanding share of Series A Preferred Stock. All payments for which this Section 4(a) provides shall be in cash, property (valued at its fair
market value as determined by an independent appraiser reasonably acceptable to the holders of a majority of the Series A Preferred Stock) or a combination thereof; provided, however, that no cash shall be paid to holders of Junior Stock
unless each holder of the outstanding shares of Series A Preferred Stock has been paid in cash the full Liquidation Preference Amount plus any accrued and unpaid dividends to which such holder is entitled as provided herein. After payment of the
full Liquidation Preference Amount plus any accrued and unpaid dividends to which each

5

holder is entitled, such holders of shares of Series A Preferred Stock will not be entitled to any further participation as such in any distribution of the assets of the Company.

          (b) A consolidation or merger of the Company with or into any other corporation or corporations, or a sale of all or substantially all of the assets of the Company, or the effectuation by the Company of a transaction or
series of related transactions in which more than 50% of the voting shares of the Company is disposed of or conveyed, shall not be deemed to be a liquidation, dissolution, or winding up within the meaning of this Section 4. In the event of the
merger or consolidation of the Company with or into another corporation, the Series A Preferred Stock shall maintain its relative powers, designations and preferences provided for herein and no merger shall result which is inconsistent therewith
unless otherwise approved by at least seventy-five percent (75%) of the then outstanding shares of Series A Preferred Stock; provided, however, that the number of outstanding shares of Preferred Stock must be greater than two hundred thousand
(200,000) for the voting rights set out in this Section to apply.

          (c) Written notice of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, stating a payment date and the place where the distributable amounts shall be payable, shall be
given by mail, postage prepaid, no less than forty-five (45) days prior to the payment date stated therein, to the holders of record of the Series A Preferred Stock at their respective addresses as the same shall appear on the books of the
Company.

     5. Conversion. The holder of Series A Preferred Stock shall have the following conversion rights (the “Conversion Rights”):

          (a) Right to Convert. At any time on or after the Issuance Date, the holder of any such shares of Series A Preferred Stock may, at such holder’s option, subject to the limitations set forth in Section 7
herein, elect to convert (a “Conversion”) all or any portion of the shares of Series A Preferred Stock held by such person (provided that the minimum amount of such shares converted shall be two hundred thousand (200,000)) into a number of
fully paid and nonassessable shares of Common Stock equal to the quotient of (i) the Liquidation Preference Amount of the shares of Series A Preferred Stock being converted by (ii) the Conversion Price (as defined in Section 5(d) below) then in
effect as of the date of the delivery by such holder of its notice of election to convert. In the event of a notice of redemption of any shares of Series A Preferred Stock pursuant to Section 8 hereof, the Conversion Rights of the shares designated
for redemption shall terminate at the close of business on the last full day preceding the date fixed for redemption, unless the redemption price is not paid on such redemption date, in which case the Conversion Rights for such shares shall continue
until such price is paid in full. In the event of a liquidation, dissolution or winding up of the Company, the Conversion Rights shall terminate at the close of business on the last full day preceding the date fixed for the payment of any such
amounts distributable on such event to the holders of Series A Preferred Stock. In the event of such a redemption or liquidation, dissolution or winding up, the Company shall provide to each holder of shares of Series A Preferred Stock notice of
such redemption or liquidation, dissolution or winding up, which notice shall (i) be sent at least fifteen (15) days prior to the termination of the Conversion Rights (or, if the Company obtains lesser notice thereof, then as promptly as possible
after the date that it has obtained notice thereof) and

6

(ii) state the amount per share of Series A Preferred Stock that will be paid or distributed on such redemption or liquidation, dissolution or winding up, as the case may be.

          (b) Mechanics of Conversion. The Conversion of Series A Preferred Stock shall be conducted in the following manner:

               (i) Holder’s Delivery Requirements. To convert Series A Preferred Stock into full shares of Common Stock on any date (the “Conversion Date”), the holder thereof shall (A) transmit by facsimile (or
otherwise deliver), for receipt on or prior to 5:00 p.m., New York time on such date, a copy of a fully executed notice of conversion in the form attached hereto as Exhibit I (the “Conversion Notice”), to the Company at (817 Winchester
Road, Suite 200, Lexington, Kentucky 40505), Attention: Chief Executive Officer, and (B) deliver via overnight delivery service to the Company as soon as practicable following such Conversion Date the original certificates representing the shares of
Series A Preferred Stock being converted (or an indemnification undertaking with respect to such shares in the case of their loss, theft or destruction) (the “Preferred Stock Certificates”) and the originally executed Conversion
Notice.

               (ii) Company’s Response. Upon receipt by the Company of a facsimile copy of a Conversion Notice, the Company shall immediately send, via facsimile, a confirmation of receipt of such Conversion Notice to such
holder. Upon receipt by the Company of a copy of the fully executed Conversion Notice and any original certificates representing the shares of Series A Preferred Stock being converted, the Company or its designated transfer agent (the “Transfer
Agent”), as applicable, shall, within three (3) business days following the date of receipt by the Company of the fully executed Conversion Notice and any original certificates representing the shares of Series A Preferred Stock being
converted, issue and deliver to the Depository Trust Company, (“DTC”) account on the Holder’s behalf via the Deposit Withdrawal Agent Commission System (“DWAC”) as specified in the Conversion Notice, or via
physical certificate if so specified in the Conversion Notice, registered in the name of the holder or its designee, for the number of shares of Common Stock to which the holder shall be entitled. Notwithstanding the foregoing to the contrary, the
Company or its Transfer Agent shall only be obligated to issue and deliver the shares to the DTC, on a holder’s behalf via DWAC if a registration statement providing for the resale of the shares of Common Stock issuable upon conversion of the
Series A Preferred Stock is effective or such shares are otherwise eligible for legend removal, and if the Transfer Agent is a participant in the DWAC system. If the shares of Common Stock to be received pursuant to the Conversion Notice are not
registered or otherwise eligible for legend removal, the Transfer Agent shall issue a physical certificate in the name of the holder representing such shares with a restrictive legend as set forth in the Purchase Agreement and a notation that such
shares are deemed owned by the holder as of the Issuance Date for purposes of determining the holder’s holding period under Rule 144 of the Securities Act of 1933, as amended. If the number of shares of Preferred Stock represented by the
Preferred Stock Certificate(s) submitted for conversion is greater than the number of shares of Series A Preferred Stock being converted, then the Company shall, as soon as practicable and in no event later than three (3) business days after receipt
of the Preferred Stock Certificate(s) and at the Company’s expense, issue and deliver to the holder a new Preferred Stock Certificate representing the number of shares of Series A Preferred Stock not converted.

7

               (iii) Dispute Resolution. In the case of a dispute as to the arithmetic calculation of the number of shares of Common Stock to be issued upon conversion, the Company shall cause its Transfer Agent to promptly
issue to the holder the number of shares of Common Stock that is not disputed and shall submit the arithmetic calculations to the holder via facsimile as soon as possible, but in no event later than two (2) business days after receipt of such
holder’s Conversion Notice. If such holder and the Company are unable to agree upon the arithmetic calculation of the number of shares of Common Stock to be issued upon such conversion within one (1) business day of such disputed arithmetic
calculation being submitted to the holder, then the Company shall within one (1) business day submit via facsimile the disputed arithmetic calculation of the number of shares of Common Stock to be issued upon such conversion to the Company’s
independent, outside accountant. The Company shall cause the accountant to perform the calculations and notify the Company and the holder of the results no later than seventy-two (72) hours from the time it receives the disputed calculations. Such
accountant’s calculation shall be binding upon all parties absent manifest error. The reasonable expenses of such accountant in making such determination shall be paid by the Company, in the event the holder’s calculation was correct, or
by the holder, in the event the Company’s calculation was correct, or equally by the Company and the holder in the event that neither the Company’s or the holder’s calculation was correct. The period of time in which the Company is
required to effect conversions or redemptions under this Certificate of Designation shall be tolled with respect to the subject conversion or redemption pending resolution of any dispute by the Company made in good faith and in accordance with this
Section 5(b)(iii).

               (iv) Record Holder. The person or persons entitled to receive the shares of Common Stock issuable upon a conversion of the Series A Preferred Stock shall be treated for all purposes as the record holder or
holders of such shares of Common Stock on the Conversion Date.

               (v) Company’s Failure to Timely Convert. If within seven (7) business days of the Company’s receipt of an executed copy of the Conversion Notice (so long as the applicable Preferred Stock Certificates
and original Conversion Notice are received by the Company on or before such third business day) (the “Delivery Date”) the Transfer Agent shall fail to issue and deliver to a holder the number of shares of Common Stock to which such holder
is entitled upon such holder’s conversion of the Series A Preferred Stock or to issue a new Preferred Stock Certificate representing the number of shares of Series A Preferred Stock to which such holder is entitled pursuant to Section 5(b)(ii)
(a “Conversion Failure”), in addition to all other available remedies which such holder may pursue hereunder and under the Series A Convertible Preferred Stock Purchase Agreement (the “Purchase Agreement”) among the Company and
the initial holders of the Series A Preferred Stock (including indemnification pursuant to Section 6 thereof), the Company shall pay additional damages to such holder on each business day after such seventh (7th) business day that such
conversion is not timely effected in an amount equal to 0.5% of the product of (A) the number of shares of Common Stock not issued to the holder on a timely basis pursuant to Section 5(b)(ii) and to which such holder is entitled and, in the event
the Company has failed to deliver a Preferred Stock Certificate to the holder on a timely basis pursuant to Section 5(b)(ii), the number of shares of Common Stock issuable upon conversion of the shares of Series A Preferred Stock represented by such
Preferred Stock Certificate, as of the last possible date which the Company could have issued such Preferred Stock Certificate to such holder without violating Section 5(b)(ii) and (B) the Closing

8

Bid Price (as defined below) of the Common Stock on the last possible date which the Company could have issued such Common Stock and such Preferred Stock Certificate, as the case may be, to such holder without violating Section 5(b)(ii). If the
Company fails to pay the additional damages set forth in this Section 5(b)(v) within fifteen (15) business days of the date incurred, then such payment shall bear interest at the rate of 2.0% per month (pro rated for partial months) until such
payments are made. The term “Closing Bid Price” shall mean, for any security as of any date, the last closing bid price of such security on the OTC Bulletin Board or other quotation venue or principal exchange on which such security is
traded as reported by Bloomberg, or, if no closing bid price is reported for such security by Bloomberg, the last closing trade price of such security as reported by Bloomberg, or, if no last closing trade price is reported for such security by
Bloomberg, the average of the bid prices of any market makers for such security as reported by the Pink Sheets LLC. If the Closing Bid Price cannot be calculated for such security on such date on any of the foregoing bases, the Closing Bid Price of
such security on such date shall be the fair market value as mutually determined by the Company and the holders of a majority of the outstanding shares of Series A Preferred Stock.

               (iv) Buy-In Rights. In addition to any other rights available to the holders of Series A Preferred Stock, if the Company fails to cause its Transfer Agent to transmit to the holder a certificate or certificates
representing the shares of Common Stock issuable upon conversion of the Series A Preferred Stock on or before the Delivery Date, and if after such date the holder is required by its broker to purchase (in an open market transaction or otherwise)
shares of Common Stock to deliver in satisfaction of a sale by the holder of the shares of Common Stock issuable upon conversion of Series A Preferred Stock which the holder anticipated receiving upon such conversion (a “Buy-In”), then the
Company shall (1) pay in cash to the holder the amount by which (x) the holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the
number of shares of Common Stock issuable upon conversion of Series A Preferred Stock that the Company was required to deliver to the holder in connection with the conversion at issue times (B) the price at which the sell order giving rise to such
purchase obligation was executed, and (2) at the option of the holder, either reinstate the shares of Series A Preferred Stock and equivalent number of shares of Common Stock for which such conversion was not honored or deliver to the holder the
number of shares of Common Stock that would have been issued had the Company timely complied with its conversion and delivery obligations hereunder. For example, if the holder purchases Common Stock having a total purchase price of $11,000 to
cover a Buy-In with respect to an attempted conversion of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (1) of the immediately preceding sentence the Company shall be
required to pay to the holder $1,000. The holder shall provide the Company written notice indicating the amounts payable to the holder in respect of the Buy-In, together with applicable confirmations and other evidence reasonably requested by
the Company. Nothing herein shall limit a holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the
Company’s failure to timely deliver certificates representing shares of Common Stock upon conversion of the Series A Preferred Stock as required pursuant to the teams hereof.

          (c) Intentionally omitted.

9

          (d) Conversion Price.

               (i) The term “Conversion Price” shall mean $1.95 per share on a 1 to 1 basis, subject to adjustment under Section 5(e) hereof. Notwithstanding any adjustment hereunder, at no time shall the Conversion
Price be greater than $1.95 per share except if it is adjusted pursuant to Section 5(e)(i).

               (ii) Notwithstanding the foregoing to the contrary, if during any period (a “Black-out Period”), a holder of Series A Preferred Stock is unable to trade any Common Stock issued or issuable upon
conversion of the Series A Preferred Stock immediately due to the postponement of filing or delay or suspension of effectiveness of the Registration Statement or because the Company has otherwise informed such holder of Series A Preferred Stock that
an existing prospectus cannot be used at that time in the sale or transfer of such Common Stock (provided that such postponement, delay, suspension or fact that the prospectus cannot be used is not due to factors solely within the control of the
holder of Series A Preferred Stock or due to the Company exercising its rights under Section 3(n) of the Registration Rights Agreement (as defined in the Purchase Agreement) or the deadline for the effectiveness of the Registration Statement has not
passed as set forth in the Registration Rights Agreement, such holder of Series A Preferred Stock shall have the option but not the obligation on any Conversion Date within ten (10) trading days following the expiration of the Black-out Period of
using the Conversion Price applicable on such Conversion Date or any Conversion Price selected by such holder of Series A Preferred Stock that would have been applicable had such Conversion Date been at any earlier time during the Black-out Period
or within the ten (10) trading days thereafter.

          (e) Adjustments of Conversion Price.

               (i) Adjustments for Stock Splits and Combinations. If the Company shall at any time or from time to time after the Issuance Date, effect a stock split of the outstanding Common Stock, the Conversion Price shall
be proportionately decreased. If the Company shall at any time or from time to time after the Issuance Date, combine the outstanding shares of Common Stock, the Conversion Price shall be proportionately increased. Any adjustments under this Section
5(e)(i) shall be effective at the close of business on the date the stock split or combination becomes effective.

               (ii) Adjustments for Certain Dividends and Distributions. If the Company shall at any time or from time to time after the Issuance Date, make or issue or set a record date for the determination of holders of
Common Stock entitled to receive a dividend or other distribution payable in shares of Common Stock, then, and in each event, the Conversion Price shall be decreased as of the time of such issuance or, in the event such record date shall have been
fixed, as of the close of business on such record date, by multiplying the Conversion Price then in effect by a fraction:

                    (1) the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date; and

10

                    (2) the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of
shares of Common Stock issuable in payment of such dividend or distribution.

               (iii) Adjustment for Other Dividends and Distributions. If the Company shall at any time or from time to time after the Issuance Date, make or issue or set a record date for the determination of holders of Common
Stock entitled to receive a dividend or other distribution payable in securities of the Company other than shares of Common Stock, then, and in each event, an appropriate revision to the applicable Conversion Price shall be made and provision shall
be made (by adjustments of the Conversion Price or otherwise) so that the holders of Series A Preferred Stock shall receive upon conversions thereof, in addition to the number of shares of Common Stock receivable thereon, the number of securities of
the Company which they would have received had their Series A Preferred Stock been converted into Common Stock on the date of such event and had thereafter, during the period from the date of such event to and including the Conversion Date, retained
such securities (together with any distributions payable thereon during such period), giving application to all adjustments called for during such period under this Section 5(e)(iii) with respect to the rights of the holders of the Series A
Preferred Stock; provided, however, that if such record date shall have been fixed and such dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the Conversion Price shall be adjusted pursuant to
this paragraph as of the time of actual payment of such dividends or distributions, and provided further, however, that no such adjustment shall be made if the holders of Series A Preferred Stock simultaneously receive (i) a dividend or other
distribution of shares of Common Stock in a number equal to the number of shares of Common Stock as they would have received if all outstanding shares of Series A Preferred Stock had been converted into Common Stock on the date of such event or (ii)
a dividend or other distribution of shares of Series A Preferred Stock which are convertible, as of the date of such event, into such number of shares of Common Stock as is equal to the number of additional shares of Common Stock being issued with
respect to each share of Common Stock in such dividend or distribution,

               (iv) Adjustments for Reclassification, Exchange or Substitution. If the Common Stock issuable upon conversion of the Series A Preferred Stock at any time or from time to time after the Issuance Date shall be
changed to the same or different number of shares of any class or classes of stock, whether by reclassification, exchange, substitution or otherwise (other than by way of a stock split or combination of shares or stock dividends provided for in
Sections 5(e)(i), (ii) and (iii), or a reorganization, merger, consolidation, or sale of assets provided for in Section 5(e)(v)), then, and in each event, an appropriate revision to the Conversion Price shall be made and provisions shall be made (by
adjustments of the Conversion Price or otherwise) so that the holder of each share of Series A Preferred Stock shall have the right thereafter to convert such share of Series A Preferred Stock into the kind and amount of shares of stock and other
securities receivable upon reclassification, exchange, substitution or other change, by holders of the number of shares of Common Stock into which such share of Series A Preferred Stock might have been converted immediately prior to such
reclassification, exchange, substitution or other change, all subject to further adjustment as provided herein.

               (v) Adjustments for Reorganization, Merger, Consolidation or Sales of Assets. If at any time or from time to time after the Issuance Date there shall be a capital

11

reorganization of the Company (other than by way of a stock split or combination of shares or stock dividends or distributions provided for in Section 5(e)(i), (ii) and (iii), or a reclassification, exchange or substitution of shares provided for in
Section 5(e)(iv)), or a merger or consolidation of the Company with or into another corporation where the holders of outstanding voting securities prior to such merger or consolidation do not own over 50% of the outstanding voting securities of the
merged or consolidated entity, immediately after such merger or consolidation, or the sale of all or substantially all of the Company’s properties or assets to any other person (an “Organic Change”), then as a part of such Organic
Change an appropriate revision to the Conversion Price shall be made if necessary and provision shall be made if necessary (by adjustments of the Conversion Price or otherwise) so that the holder of each share of Series A Preferred Stock shall have
the right thereafter to convert such share of Series A Preferred Stock into the kind and amount of shares of stock and other securities or property of the Company or any successor corporation resulting from Organic Change. Notwithstanding the
foregoing, the prohibitions set forth above regarding an Organic Change shall not pertain to the Merger (as defined below), the issuance of Common Stock in connection with any future strategic acquisitions which are approved in writing by the
holders of at least seventy-five percent (75%) of the then outstanding shares of the Series A Preferred Stock, provided that the shares of Series A Preferred Stock then outstanding equal at least two hundred thousand (200,000), and
provided further that, such approval will not to be unreasonably withheld (each a “Permitted Future Transaction”). In any such case appropriate adjustment shall be made in the application of the provisions of this Section
5(e)(v) with respect to the rights of the holders of the Series A Preferred Stock after the Organic Change to the end that the provisions of this Section 5(e)(v) (including any adjustment in the Conversion Price then in effect and the number of
shares of stock or other securities deliverable upon conversion of the Series A Preferred Stock) shall be applied after that event in as nearly an equivalent manner as may be practicable.

               (vi) Adjustments for Issuance of Additional Shares of Common Stock.

          (A) For a period of twelve (12) months after the Issuance Date (the “Price Protection Period”), in the event the Company shall issue or sell any additional shares of Common Stock (otherwise than as provided in
the foregoing subsections (i) through (v) of this Section 5(e) or pursuant to Common Stock Equivalents (hereafter defined) granted or issued prior to the Issuance Date) (the “Additional Shares of Common Stock”), at a price per share
(“New Price”) less than the Conversion Price then in effect (“Down Round”), or without consideration, the Conversion Price shall be reduced concurrently with such issue to the New Price. After the Price Protection Period, the
Conversion Price shall be reset to the Conversion Price in effect immediately prior to the Down Round, and thereafter, for so long as the Series A Preferred Stock has not been converted into Common Stock, but only for a period of twelve (12) months,
the Conversion Price then in effect upon each issuance of a Down Round shall be adjusted to that price (rounded to the nearest cent) determined by multiplying the Conversion Price by a fraction:

                    (1) the numerator of which shall be equal to the sum of (A) the number of shares of Common Stock outstanding immediately prior to the issuance of such Additional Shares of Common Stock plus (B) the number of
shares of Common Stock (rounded to the nearest whole share) which the aggregate consideration for the total number of such

12

Additional Shares of Common Stock so issued would purchase at a price per share equal to the then Conversion Price, and

                    (2) the denominator of which shall be equal to the number of shares of Common Stock outstanding immediately after the issuance of such Additional Shares of Common Stock. This Section and the adjustments described herein
shall not apply to (i) the issuance of Common Stock pursuant to the agency agreement between SGPF, LLC and Medpro Safety Products, Inc. (“Medpro”), in connection with the contemplated merger between the Company and Medpro (the
“Merger”), (ii) a Permitted Future Transaction, (iii) the issuance of warrants for up to 3,000,000 shares of Common Stock of the Company in connection with an employee stock option program, incentive stock option program, or other
qualified or non-qualified employee benefit plan (an “ESOP”) to be established concurrent with the closing of the Merger, priced at $1.81 per share, to be issued to the current management of Medpro and the future management of
the Company (the “ESOP Warrants”), (iv) 68,036 warrants to be issued to Chrystal Research (the “Chrystal Research Warrants”), (v) 533,458 warrants to be issued to SC Capital Partners, LLC (the “SC Capital
Warrants”).

No adjustment of the number of shares of Common Stock shall be made under paragraph (A) of Section 5(e)(vi) upon the issuance of any Additional Shares of Common Stock which are issued pursuant to the exercise of any warrants or other subscription or
purchase rights or pursuant to the exercise of any conversion or exchange rights in any Common Stock Equivalents (as defined below); if any such adjustment shall previously have been made upon the issuance of such warrants or other rights or upon
the issuance of such Common Stock Equivalents (or upon the issuance of any warrant or other rights therefore) pursuant to Section 5(e)(vii).

               (vii) Issuance of Common Stock Equivalents. The provisions of this Section 5(e)(vii) shall apply if (a) the Company, at any time after the Issuance Date, shall issue any securities convertible into or
exchangeable for, directly or indirectly, Common Stock (“Convertible Securities”), other than the Series A Preferred Stock, or (b) any rights or warrants or options to purchase any such Common Stock or Convertible Securities (collectively,
the “Common Stock Equivalents”) shall be issued or sold. If the price per share for which Additional Shares of Common Stock may be issuable pursuant to any such Common Stock Equivalent shall be less than the applicable Conversion Price
then in effect, or if, after any such issuance of Common Stock Equivalents, the price per share for which Additional Shares of Common Stock may be issuable thereafter is amended or adjusted, and such price as so amended shall be less than the
applicable Conversion Price in effect at the time of such amendment or adjustment, then the applicable Conversion Price upon each such issuance or amendment shall be adjusted as provided in the first sentence of subsection (vi) of this Section 5(e).
No adjustment shall be made to the Conversion Price upon the issuance of Common Stock pursuant to the exercise, conversion or exchange of any Convertible Security or Common Stock Equivalent where an adjustment to the Conversion Price was made as a
result of the issuance or purchase of any Convertible Security or Common Stock Equivalent. For avoidance of doubt, the foregoing shall not apply to the ESOP Warrants.

               (viii) Consideration for Stock. In case any shares of Common Stock or Convertible Securities other than the Series A Preferred Stock, or any rights or warrants or options to purchase any such Common Stock or
Convertible Securities, shall be issued or sold:

13

                    (1) in connection with any merger or consolidation in which the Company is the surviving corporation (other than any consolidation or merger in which the previously outstanding shares of Common Stock of the Company
shall be changed to or exchanged for the stock or other securities of another corporation), the amount of consideration therefore shall be, deemed to be the fair value, as determined reasonably and in good faith by the Board of Directors of the
Company, of such portion of the assets and business of the nonsurviving corporation as such Board may determine to be attributable to such shares of Common Stock, Convertible Securities, rights or warrants or options, as the case may be; or

                    (2) in the event of any consolidation or merger of the Company in which the Company is not the surviving corporation or in which the previously outstanding shares of Common Stock of the Company shall be changed into or
exchanged for the stock or other securities of another corporation, or in the event of any sale of all or substantially all of the assets of the Company for stock or other securities of any corporation, the Company shall be deemed to have issued a
number of shares of its Common Stock for stock or securities or other property of the other corporation computed on the basis of the actual exchange ratio on which the transaction was predicated, and for a consideration equal to the fair market
value on the date of such transaction of all such stock or securities or other property of the other corporation. If any such calculation results in adjustment of the applicable Conversion Price, or the number of shares of Common Stock issuable upon
conversion of the Series A Preferred Stock, the determination of the applicable Conversion Price or the number of shares of Common Stock issuable upon conversion of the Series A Preferred Stock immediately prior to such merger, consolidation or
sale, shall be made after giving effect to such adjustment of the number of shares of Common Stock issuable upon conversion of the Series A Preferred Stock. In the event any consideration received by the Company for any securities consists of
property other than cash, the fair market value thereof at the time of issuance or as otherwise applicable shall be as determined in good faith by the Board of Directors of the Company. In the event Common Stock is issued with other shares or
securities or other assets of the Company for consideration which covers both, the consideration computed as provided in this Section (5)(e)(viii) shall be allocated among such securities and assets as determined in good faith by the Board of
Directors of the Company.

               (ix) Record Date. In case the Company shall take record of the holders of its Common Stock or any other Preferred Stock for the purpose of entitling them to subscribe for or purchase Common Stock or Convertible
Securities, then the date of the issue or sale of the shares of Common Stock shall be deemed to be such record date.

               (x) Certain Issues Excepted. Anything in Section 5(e) or otherwise in this Agreement to the contrary notwithstanding, the Company shall not be required to make any adjustment to the Conversion Price upon (i)
securities issued (other than for cash) in connection with a merger, acquisition, or consolidation, (ii) securities issued pursuant to the conversion or exercise of convertible or exercisable securities issued or outstanding on or prior to the date
of the Purchase Agreement or issued pursuant to the Purchase Agreement (so long as the conversion or exercise price in such securities are not amended to lower such price and/or adversely affect the holders), (iii) Common Stock issued or the
issuance or grants of options to purchase Common Stock pursuant to the Issuer’s stock option plans and employee stock purchase plans outstanding as they exist on the date of the purchase Agreement, (iv) any

14

warrants issued to the placement agent and its designees for the transactions contemplated by the Purchase Agreement, (v) ESOP Warrants, (vi) the Chrystal Research Warrants, (vii) the SC Capital Warrants, (viii) the issuance of Common Stock pursuant
to Medpro’s agency agreement with SGPF, Inc., (ix) issuance of Common Stock issued in connection with a Permitted Future Transaction, (x) the Merger.

          (f) No Impairment. The Company shall not, by amendment of its Articles of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any
other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in the carrying out of all the provisions of this
Section 5 and in the taking of all such action as may be necessary or appropriate in order to protect the Conversion Rights of the holders of the Series A Preferred Stock against impairment. In the event a holder shall elect to convert any shares of
Series A Preferred Stock as provided herein, the Company cannot refuse conversion based on any claim that such holder or any one associated or affiliated with such holder has been engaged in any violation of law, unless (i) an order from the
Securities and Exchange Commission prohibiting such conversion or (ii) an injunction from a court, on notice, restraining and/or adjoining conversion of all or of said shares of Series A Preferred Stock shall have been issued and the Company posts a
surety bond for the benefit of such holder in an amount equal to 120% of the Liquidation Preference Amount of the Series A Preferred Stock such holder has elected to convert, which bond shall remain in effect until the completion of
arbitration/litigation of the dispute and the proceeds of which shall be payable to such holder in the event it obtains judgment in its favor.

          (g) Certificates as to Adjustments. Upon occurrence of each adjustment of readjustment of the Conversion Price or number of shares of Common Stock issuable upon conversion of the Series A Preferred Stock pursuant
to this Section 5, the Company at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to each holder of such Series A Preferred Stock a certificate setting forth such adjustment and
readjustment, showing in detail the facts upon which such adjustment or readjustment is based. The Company shall, upon written request of the holder of such affected Series A Preferred Stock, at any time, furnish or cause to be furnished to such
holder a like certificate setting forth such adjustments and readjustments, the Conversion Price in effect at the time, and the number of shares of Common Stock and the amount, if any, of other securities or property which at the time would be
received upon the conversion of a share of such Series A Preferred Stock. Notwithstanding the foregoing, the Company shall not be obligated to deliver a certificate unless such certificate would reflect an increase or decrease of at least one
percent of such adjusted amount.

          (h) Issue Taxes. The Company shall pay any and all issue and other taxes, excluding federal, state or local income taxes, that may be payable in respect of any issue or delivery of shares of Common Stock on
conversion of shares of Series A Preferred Stock pursuant hereto; provided, however, that the Company shall not be obligated to pay any transfer taxes resulting from any transfer requested by any holder in connection with any such
conversion.

15

          (i) Notices. All notices and other communications hereunder shall be in writing and shall be deemed given if delivered personally or by facsimile or three (3) business days following being mailed by certified or
registered mail, postage prepaid, return-receipt requested, addressed to the holder of record at its address appearing on the books of the Company. The Company will give written notice to each holder of Series A Preferred Stock at least twenty (20)
days prior to the date on which the Company closes its books or takes a record (I) with respect to any dividend or distribution upon the Common Stock, (II) with respect to any pro rata subscription offer to holders of Common Stock or (III) for
determining rights to vote with respect to any Organic Change, dissolution, liquidation or winding-up and in no event shall such notice be provided to such holder prior to such information being made known to the public. The Company will also give
written notice to each holder of Series A Preferred Stock at least twenty (20) days prior to the date on which any Organic Change, dissolution, liquidation or winding-up will take place and in no event shall such notice be provided to such holder
prior to such information being made known to the public.

          (j) Fractional Shares. No fractional shares of Common Stock shall be issued upon conversion of the Series A Preferred Stock. In lieu of any fractional shares to which the holder would otherwise be entitled, the
Company shall round the number of shares to be issued upon conversion up to the nearest whole number of shares.

          (k) Reservation of Common Stock. The Company shall, so long as any shares of Series A Preferred Stock are outstanding, reserve and keep available out of its authorized and unissued Common Stock, solely for the
purpose of effecting the conversion of the Series A Preferred Stock, such number of shares of Common Stock that are not issued or reserved for issuance as of the Issuance Date; provided, however, upon the Company filing the Charter Amendment
(as defined in the Purchase Agreement), the Company shall take all action necessary to at all times have authorized, and reserved for the purpose of issuance, free of preemptive rights and other similar contractual rights of stockholders, a number
of shares of Common Stock equal to one hundred fifty percent (150%) of the number of shares of Common Stock as shall from time to time be sufficient to effect the conversion of all of the shares of Series A Preferred Stock then outstanding. The
initial number of shares of Common Stock reserved for conversions of the Series A Preferred Stock and any increase in the number of shares so reserved shall be allocated pro rata among the holders of the Series A Preferred Stock based on the number
of shares of Series A Preferred Stock held by each holder of record at the time of issuance of the Series A Preferred Stock or increase in the number of reserved shares, as the case may be. In the event a holder shall sell or otherwise transfer any
of such holder’s shares of Series A Preferred Stock; each transferee shall be allocated a pro rata portion of the number of reserved shares of Common Stock reserved for such transferor.

          (l) Retirement of Series A Preferred Stock. Conversion of Series A Preferred Stock shall be deemed to have been effected on the Conversion Date. Upon conversion of only a portion of the number of shares of Series
A Preferred Stock represented by a certificate surrendered for conversion, the Company shall issue and deliver to such holder at the expense of the Company, a new certificate covering the number of shares of Series A Preferred Stock representing the
unconverted portion of the certificate so surrendered as required by Section 5(b)(ii.).

16

          (m) Regulatory Compliance. If any shares of Common Stock to be reserved for the purpose of conversion of Series A Preferred Stock require registration or listing with or approval of any governmental authority,
stock exchange or other regulatory body under any federal or state law or regulation or otherwise before such shares may be validly issued or delivered upon conversion, the Company shall, at its sole cost and expense, in good faith and as
expeditiously as possible, endeavor to secure such registration, listing or approval, as the case may be.

     6. No Preemptive Rights. Except as provided in Section 5 hereof and in the Purchase Agreement, no holder of the Series A Preferred Stock shall be entitled to rights to subscribe for, purchase or receive any part
of any new or additional shares of any class, whether now or hereinafter authorized, or of bonds or debentures, or other evidences of indebtedness convertible into or exchangeable for shares of any class, but all such new or additional shares of any
class, or any bond, debentures or other evidences of indebtedness convertible into or exchangeable for shares, may be issued and disposed of by the Board of Directors on such terns and for such consideration (to the extent permitted by law), and to
such person or persons as the Board of Directors in their absolute discretion may deem advisable.

     7. Conversion Restriction. Notwithstanding anything to the contrary set forth in Section 5 of this Certificate of Designation, at no time may a holder of shares of Series A Preferred Stock convert shares of the
Series A Preferred Stock if the number of shares of Common Stock to be issued pursuant to such conversion would cause the number of shares of Common Stock owned by such holder at such time to exceed, when aggregated with all other shares of Common
Stock owned by such holder at such time, the number of shares of Common Stock which would result in such holder beneficially owning (as determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and the rules
thereunder) in excess of 9.9% of the then issued and outstanding shares of Common Stock outstanding at such time; provided, however, that upon a holder of Series A Preferred Stock providing the Company with sixty-one (61) days notice
(pursuant to Section 5(i) hereof) (the “Waiver Notice”) that such holder would like to waive Section 7 of this Certificate of Designation with regard to any or all shares of Common Stock issuable upon conversion of Series A Preferred
Stock, this Section 7(a) shall be of no force or effect with regard to those shares of Series A Preferred Stock referenced in the Waiver Notice.

8. Redemption.

          (a) Redemption Option Upon Major Transaction. In addition to all other rights of the holders of Series A Preferred Stock contained herein, simultaneous with the occurrence of a Major Transaction (as defined
below), each holder of Series A Preferred Stock shall have the right, at such holder’s option, to require the Company to redeem all or a portion of such holder’s shares of Series A Preferred Stock at a price per share of Series A Preferred
Stock equal to one hundred percent (100%) of the Liquidation Preference Amount, plus any accrued but unpaid dividends (the “Major Transaction Redemption Price”); provided that the Company shall have the sole option to pay the Major
Transaction Redemption Price in cash or shares of Common Stock. If the Company elects to pay the Major Transaction Redemption Price in shares of Common Stock, the price per share shall be based upon the Conversion Price then in effect on the day
preceding the date of delivery of the Notice of Redemption at Option of Buyer Upon

17

Major Transaction (as hereafter defined) and the holder of such shares of Common Stock shall have demand registration rights with respect to such shares.

          (b) Redemption Option Upon Triggering Event. In addition to all other rights of the holders of Series A Preferred Stock contained herein, after a Triggering Event (as defined below), each holder of Series A
Preferred Stock shall have the right, at such holder’s option., to require the Company to redeem all or a portion of such holder’s shares of Series A Preferred Stock at a price per share of Series A Preferred Stock equal to one hundred
twenty percent (120%) of the Liquidation Preference Amount, plus any accrued but unpaid dividends and liquidated damages the “‘Triggering Event Redemption price” and, collectively with the “Major Transaction Redemption
Price,” the “Redemption Price”); provided that with respect to the Triggering Events described in clauses (i), (ii), (iii) and (vii) of Section 8(d), the Company shall have the sole option to pay the Triggering Event Redemption
Price in cash or shares of Common Stock.; and provided, further, that with respect to the Triggering Event described in clauses (iv), (v), (vi) and (viii) of Section 8(d), the Company shall pay the Triggering Event Redemption Price in cash.
If the Company elects to pay the Triggering Event Redemption Price in shares of Common Stock in accordance with this Section 8(b), the price per share shall be based upon the Conversion Price then in effect on the day preceding the date of delivery
of the Notice of Redemption at Option of Buyer Upon Triggering Event and the holder of such shares of Common Stock shall have demand registration rights with respect to such shares.

          (c) “Major Transaction”. A “Major Transaction” shall be deemed to have occurred at such time as any of the following events occur:

               (i) the consolidation, merger or other business combination of the Company with or into another Person (other than (A) pursuant to a migratory merger effected solely for the purpose of changing the jurisdiction of
incorporation of the Company, (B) a Permitted Future Transaction, or (C) a consolidation, merger or other business combination in which holders of the Company’s voting power immediately prior to the transaction continue after the transaction to
hold, directly or indirectly, the voting power of the surviving entity or entities necessary to elect a majority of the members of the board of directors (or their equivalent if other than a corporation) of such entity or entities).

               (ii) the sale or transfer of more than 50% of the Company’s assets other than inventory in the ordinary course of business in one or a related series of transactions; or

               (iii) closing of a purchase, tender or exchange offer made to the holders of more than fifty percent (50%) of the outstanding shares of Common Stock in which more than fifty percent (50%) of the outstanding shares of
Common Stock were tendered and accepted.

          (d) “Triggering Event”. A “Triggering Event” shall be deemed to have occurred at such time as any of the following, events:

               (i) so long as any shares of Series A Preferred Stock are outstanding, the effectiveness of the Registration Statement, after it becomes effective, (i) lapses for any reason (including, without limitation, the issuance
of a stop order) and such lapse continues for a

18

period of twenty (20) consecutive trading, days, or (ii) is unavailable to the holder of the Series A Preferred Stock for sale of the shares of Common Stock, and such lapse or unavailability continues for a period of twenty (20) consecutive trading
days, and the shares of Common Stock into which such holder’s Series A Preferred Stock can be converted cannot be sold in the public securities market pursuant to Rule 144(k) (“Rule 144(k)”) under the Securities Act of 1933, as
amended, provided that the cause of such lapse or unavailability is not due to factors solely within the control of such holder of Series A Preferred Stock.

               (ii) the suspension from listing or trading, without subsequent listing on any one of or the failure of the Common Stock to be listed or traded on at least one of, the OTC Bulletin Board, the Nasdaq National Market, the
Nasdaq Global Market, the New York Stock Exchange, Inc. or the American Stock Exchange, Inc., for a period of five (5) consecutive trading days;

               (iii) the Company’s notice to any holder of Series A Preferred Stock, including by way of public announcement, at any time, of its inability to comply (including for any of the reasons described in Section 9) or
its intention not to comply with proper requests for conversion of any Series A Preferred Stock into shares of Common stock; or

               (iv) the Company’s failure to comply with a Conversion Notice tendered in accordance with the provisions of this Certificate of Designation within fifteen (15) business days after the receipt by the Company of the
Conversion Notice and the Preferred Stock Certificates; provided, however, that this Triggering Event is only a Triggering Event as to the entity tendering the Conversion Notice the Company failed to comply with and the other provisions in this
Section 8 shall only be effective upon this Triggering Event, as to this one entity; or

               (v) the Company deregisters its shares of Common Stock and as a result such shares of Common Stock are no longer publicly traded; or

               (vi) the Company consummates a “going private” transaction and as a result the Common Stock is no longer registered under Sections 12(b) or 12(g) of the Securities Exchange Act of 1934, as amended; or

               (vii) the Company breaches any representation, warranty, covenant or other term or condition of the Purchase agreement, this Certificate of Designation or any other agreement, document, certificate or other instrument
delivered in connection with the transactions contemplated thereby or hereby, except to the extent that such breach would not have a Material Adverse Effect (as defined in the Purchase Agreement) and except, in the case of a breach of a covenant
which is curable, only if such breach continues for a period of a least ten (10) business days.

          (e) Mechanics of Redemption at Option of Buyer Upon Major Transaction. No sooner than thirty (30) days nor later than ten (10) days prior to the consummation of a Major Transaction, but not prior to the public
announcement of such Major Transaction, the Company shall deliver written notice thereof via facsimile and overnight courier (“Notice of Major Transaction”) to each holder of Series a Preferred Stock. At any time after receipt of a Notice
of

19

Major Transaction (or, in the event a Notice of Major Transaction is not delivered at least ten (10) days prior to a Major Transaction, at any time within ten (10) days prior to a Major Transaction), any holder of Series A Preferred Stock then
outstanding may require the Company to redeem, effective immediately prior to the consummation of such Major Transaction, all of the holder’s Series A Preferred Stock then outstanding by delivering written notice thereof via facsimile and
overnight courier (“Notice of Redemption at Option of Buyer Upon Major Transaction”) to the Company, which Notice of Redemption at Option of Buyer Upon Major Transaction shall indicate (i) the number of shares of Series A Preferred Stock
that such holder is electing to redeem and (ii) the applicable Major Transaction Redemption Price, as calculated pursuant to Section 8(a) above.

          (f) Mechanics of Redemption at Option of Buyer Upon Triggering Event. Within five (5) business days after the Company obtains knowledge of the occurrence of a Triggering Event, the Company shall deliver written
notice thereof via facsimile and overnight courier (“Notice of Triggering Event”) to each holder of Series A Preferred Stock except in the case of a Triggering Event under Section 8(d) (iv). At any time after the earlier of a holder’s
receipt of a Notice of Triggering Event and such holder becoming aware of a Triggering Event, any holder of Series A Preferred Stock then outstanding may require the Company to redeem all of the Series A Preferred Stock by delivering written notice
thereof via facsimile and overnight courier (“Notice of Redemption at Option of Buyer Upon Triggering Event”) to the Company, which Notice of Redemption at Option of Buyer Upon Triggering Event shall indicate (i) the number of shares of
Series A Preferred Stock that such holder is electing to redeem and (ii) the applicable Triggering Event Redemption Price, as calculated pursuant to Section 8(b) above.

          (g) Payment of Redemption Price. Upon the Company’s receipt of a Notice(s) of Redemption at Option of Buyer Upon Triggering Event or a Notice(s) of Redemption at Option of Buyer Upon Major Transaction from
any holder of Series A Preferred Stock, the Company shall immediately notify such holder of Series A Preferred Stock by facsimile of the Company’s receipt of such Notice(s) of Redemption at Option of Buyer Upon Triggering Event or Notice(s) of
Redemption at Option of Buyer Upon Major Transaction and each holder which has sent such a notice shall promptly submit to the Company such holder’s Preferred Stock Certificates which such holder has elected to have redeemed. Other than with
respect to the Triggering Event described in clause (iv) of Section 8(d), the Company shall have the sole option to pay the Redemption Price in cash or shares of Common Stock in accordance with Sections 8(a) and (b) and Section 9 of this Certificate
of Designation. The Company shall deliver the applicable Major Transaction Redemption Price immediately prior to the consummation of the Major Transaction, provided that a holder’s Preferred Stock Certificates shall have been so
delivered to the Company; provided further that if the Company is unable to redeem all of the Series A Preferred Stock to be redeemed, the Company shall redeem an amount from each holder of Series A Preferred Stock being redeemed equal to
such holder’s pro-rata amount (based on the number of shares of Series A Preferred Stock held by such holder relative to the number of shares of Series A Preferred Stock outstanding) of all Series A Preferred Stock being redeemed. If the
Company shall fail to redeem all of the Series A Preferred Stock submitted for redemption (other than pursuant to a dispute as to the arithmetic calculation of the Redemption Price), in addition to any remedy such holder of Series A Preferred Stock
may have under this Certificate of Designation and the Purchase Agreement, the applicable Redemption Price payable in respect of such unredeemed Series A Preferred Stock shall bear interest at the

rate of 1.0% per month (prorated for partial months) until paid in full. Until the Company pays such unpaid applicable Redemption Price in full to a holder of shares of Series A Preferred Stock submitted for redemption, such holder shall have the
option (the “Void Optional Redemption Option”) to, in lieu of redemption, require the Company to promptly return to such holder(s) all of the shares of Series A Preferred Stock that were submitted for redemption by such holder(s) under
this Section 8 and for which the applicable Redemption Price has not been paid, by sending written notice thereof to the Company via facsimile (the “Void Optional Redemption Notice”). Upon the Company’s receipt of such Void Optional
Redemption Notice(s) and prior to payment of the full applicable Redemption Price to such holder, (i) the Notice(s) of Redemption at Option of buyer Upon Major Transaction or Notice(s) of Redemption at Option of Buyer Upon Triggering Event (as
applicable) shall be null and void with respect to those shares of Series A Preferred Stock submitted for redemption and for which the applicable Redemption Price has not been paid and (ii) the Company shall immediately return any Series A Preferred
Stock submitted to the Company by each holder for redemption under this Section 8(d) and for which the applicable Redemption Price has not been paid; provided that no adjustment shall be made if such adjustment would result in an increase of
the Conversion Price then in effect. A holder’s delivery of a Void Optional Redemption Notice and exercise of its rights following such notice shall not effect the Company’s obligations to make any payments which have accrued prior to the
date of such notice other than interest payments. Payments provided for in this Section 8 shall have priority to payments to other stockholders in connection with a Major Transaction.

          (h) Demand Registration Rights. If the Redemption Price upon the occurrence of a Major Transaction or a Triggering Event is paid in shares of Common Stock and such shares have not been previously registered on a
registration statement under the Securities Act, a holder of Series A Preferred Stock may make a written request for registration under the Securities Act pursuant to this Section 8(h) of all of its shares of Common Stock issued upon such Major
Transaction or Triggering Event. The Company shall use its reasonable best efforts to cause to be filed and declared effective as soon as reasonably practicable (but in no event later than the one hundred and twentieth (120th) day after
such holder’s request is made) a registration statement under the Securities Act, providing for the sale of all of the shares of Common Stock issued upon such Major Transaction or Triggering Event by such holder. The Company agrees to use its
reasonable best efforts to keep any such registration statement continuously effective for resale of the Common Stock for so long as such holder shall request, but in no event shall the Company be required to maintain the effectiveness of such
registration statement later than the date that the shares of Common Stock issued upon such Major Transaction or Triggering Event may be offered for resale to the public pursuant to Rule 144(k).

     9. Inability to Fully Convert.

          (a) Holder’s Option if Company Cannot Fully Convert. If, upon the Company’s receipt of a Conversion Notice, the Company cannot issue shares of Common Stock registered for resale under the Registration
Statement (and such Registration Statement is required to be in effect per the terms of the Registration Rights Agreement) for any reason, including, without limitation, because the Company (w) does not have a sufficient number of shares of Common
Stock authorized and available, (x) is otherwise prohibited by applicable law or by the rules or regulations of any stock exchange, interdealer quotation system or other self-

21

regulatory organization with jurisdiction over the Company or its securities from issuing all of the Common Stock which is to be issued to a holder of Series A Preferred Stock pursuant to a Conversion Notice or (y) subsequent to the effective date
of the Registration Statement, fails to have a sufficient number of shares of Common Stock registered for resale under the Registration Statement, then the Company shall issue as many shares of Common Stock as it is able to issue in accordance with
such holder’s Conversion Notice and pursuant to Section 5(b)(ii) above and, with respect to the unconverted Series A Preferred Stock, the holder, solely at such holder’s option, can elect, within five (5) business days after receipt of
notice from the Company thereof to:

               (i) require the Company to redeem from such holder those Series A Preferred Stock for which the Company is unable to issue Common Stock in accordance with such holder’s Conversion Notice (“Mandatory
Redemption”) at a price per share equal to the Major Transaction Redemption Price as of such Conversion Date (the “Mandatory Redemption Price”); provided that the Company shall have the sole option to pay the Mandatory Redemption
Price in cash or, subject to Section 7 hereof, shares of Common Stock; or

               (ii) if the Company’s inability to fully convert Series A Preferred Stock is pursuant to Section 9(a)(y) above, require the Company to issue restricted shares of Common Stock in accordance with such holder’s
Conversion Notice and pursuant to Section 5(b)(ii) above; or

               (iii) void its Conversion Notice and retain or have returned, as the case may be the shares of Series A Preferred Stock that were to be converted pursuant to such holder’s Conversion Notice (provided that a
holder’s voiding its Conversion Notice shall not effect the Company’s obligations to make any payments which have accrued prior to the date of such notice); or

               (iv) exercise its Buy-In rights pursuant to and in accordance with the terms and provisions of Section 5(b)(vi) hereof.

          (b) Mechanics of Fulfilling Holder’s Election. The Company shall promptly send via facsimile or overnight courier to a holder of Series A Preferred Stock, upon receipt of an original or facsimile copy of a
Conversion Notice from such holder which cannot be fully satisfied as described in Section 9(a) above, a notice of the Company’s inability to fully satisfy such holder’s Conversion Notice (the “Inability to Fully Convert
Notice”). Such Inability to Fully Convert Notice shall indicate (i) the reason why the Company is unable to fully satisfy such holder’s Conversion Notice, (ii) the number of Series A Preferred Stock which cannot be converted and (iii) the
applicable Mandatory Redemption Price, Such holder shall notify the Company of its election pursuant to Section 9(a) above by delivering written notice via facsimile to the Company (“Notice in Response to Inability to Convert”).

          (c) Payment of Redemption Price. If such holder shall elect to have its shares redeemed pursuant to Section 9(a)(i) above, the Company shall pay the Mandatory Redemption Price to such holder within thirty (30)
days of the Company’s receipt of the holder’s Notice in Response to Inability to Convert, provided that prior to the Company’s receipt of the holder’s Notice in Response to Inability to Convert the Company has not
delivered a notice to such holder

22

stating, to the satisfaction of the holder, that the event or condition resulting in the Mandatory Redemption has been cured and all Conversion Shares issuable to such holder can and will be delivered to the holder in accordance with the terms of
Section 2(g). If the Company shall fail to pay the applicable Mandatory Redemption Price to such holder on a timely basis as described in this Section 9(c) (other than pursuant to a dispute as to the determination of the arithmetic calculation of
the Redemption Price), in addition to any remedy such holder of Series A Preferred Stock may have under this Certificate of Designation and the Purchase Agreement, such unpaid amount shall bear interest at the rate of 2.0% per month (prorated for
partial months) until paid in full. Until the full Mandatory Redemption Price is paid in full to such holder, such holder may (i) void the Mandatory Redemption with respect to those Series A Preferred Stock for which the full Mandatory Redemption
Price has not been paid, (ii) receive back such Series A Preferred Stock, and (iii) require that the Conversion Price of such returned Series A Preferred Stock be adjusted to the lesser of (A) the Conversion Price and (B) the lowest Closing Bid
Price during the period beginning on the Conversion Date and ending on the date the holder voided the Mandatory Redemption.

          (d) Pro-rata Conversion and Redemption. In the event the Company receives a Conversion Notice from more than one holder of Series A Preferred Stock on the same day and the Company can convert and redeem some, but
not all, of the Series A Preferred Stock pursuant to this Section 9, the Company shall convert and redeem from each holder of Series A Preferred Stock electing to have Series A Preferred Stock converted and redeemed at such time an amount equal to
such holder’s pro-rata amount (based on the number shares of Series A Preferred Stock held by such holder relative to the number shares of Series A Preferred Stock outstanding) of all shares of Series A Preferred Stock being converted and
redeemed at such time.

     10. Vote to Change the Terms of or Issue Preferred Stock. The affirmative vote at a meeting duly called for such purpose or the written consent without a meeting, of the holders of not less than seventy-five
percent (75%) of the then outstanding shares of Series A Preferred Stock; provided, however, that this provision is no longer effective once shares of Preferred Stock outstanding shall equal less than two hundred thousand (200,000) (in addition to
any other corporate approvals then required to effect such action), shall be required (a) for any change to this Certificate of Designation or the Company’s Articles of Incorporation which would amend, alter, change or repeal any of the powers,
designations, preferences and rights of the Series A Preferred Stock or (b) for the issuance of shares of Series A Preferred Stock other than pursuant to the Purchase Agreement.

     11. Lost or Stolen Certificates. Upon receipt by the Company of evidence satisfactory to the Company of the loss, theft, destruction or mutilation of any Preferred Stock Certificates representing the shares of
Series A Preferred Stock, and, in the case of loss, theft or destruction, of any indemnification undertaking by the holder to the Company that is reasonably acceptable to the Company and, in the case of mutilation; upon surrender and cancellation of
the Preferred Stock Certificate(s), the Company shall execute and deliver new preferred stock certificate(s) of like tenor and date, provided, however, that the Company shall not be obligated to re-issue Preferred Stock Certificates if the
holder contemporaneously requests the Company to convert such shares of Series A Preferred Stock into Common Stock.

23

     12. Remedies, Characterizations, Other Obligations, Breaches and Injunctive Relief. The remedies provided in this Certificate of Designation shall be cumulative and in addition to all other remedies available
under this Certificate of Designation, at law or in equity (including a decree of specific performance and/or other injunctive relief). No remedy contained herein shall be deemed a waiver of compliance with the provisions giving rise to such remedy
and nothing herein shall limit a holder’s right to pursue actual damages for any failure by the Company to comply with the terms of this Certificate of Designation. Amounts set forth or provided for herein with respect to payments, conversion
and the like (and the computation thereof) shall be the amounts to be received by the holder thereof and shall not, except as expressly provided herein, be subject to any other obligation of the Company (or the performance thereof). The Company
acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the holders of the Series A Preferred Stock and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the
event of any such breach or threatened breach, the holders of the Series A Preferred Stock shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and
without any bond or other security being required.

     13. Specific Shall Not Limit General; Construction. No specific provision contained in this Certificate of Designation shall limit or modify any more general provision contained herein. This Certificate of
Designation shall be deemed to be jointly drafted by the Company and all initial purchasers of the Series A Preferred Stock and shall not he construed against any person as the drafter hereof.

     14. Failure or Indulgence Not Waiver. No failure or delay on the part of a holder of Series A Preferred Stock in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or privilege.

24

     IN WITNESS WHEREOF, the undersigned has executed and subscribed this Certificate and does affirm the foregoing as true this 5th day of September, 2007.
