(b) *Optional Right to Convert*. Each share of Series A Preferred Stock shall be convertible, atthe option of the holder thereof, at any time and from time to time, into such number of fully paid and nonassessable shares of Common Stock as is determined by dividing $11.00 per share of Series A Preferred Stock (the “Original Series AIssue Price”), plus (to the extent the Company and such holder jointly elect to include the amount of Accrued Dividends in the conversion) Accrued Dividends, by the Conversion Price (as defined below) in effect at the time of conversion.The Conversion Price at which shares of Common Stock shall be deliverable upon conversion of Series A Preferred Stock without the payment of additional consideration by the holder thereof (the “Conversion Price”) shall initially bethe Original Series A Issue Price.

In the event of a liquidation of the Company, the Conversion Rights shall terminate at the close of business on the first full daypreceding the date fixed for the payment of any amounts distributable on liquidation to the holders of Series A Preferred Stock. 

(c) *Mechanics of Conversion*. 

(i) In order to convert shares of Series APreferred Stock into shares of Common Stock in accordance with this Section 5, the holder shall (A) in the event of a conversion pursuant to Subsection 5(a)(i)(B) or Subsection 5(b) (an “Elective Conversion”), providewritten notice to the Company that such holder elects to convert all or any number of the shares represented by such certificate or certificates and the date of conversion which notice, if notice is provided after February 26, 2014, must bereceived by the Company at least sixty (60) days prior to the date selected by the holder for conversion (the “Conversion Notice”), (B) surrender the certificate or certificates for such shares of Series A Preferred Stockat the office of the transfer agent (or at the principal office of the Company if the Company serves as its own transfer agent), and (C) state in writing such holder’s name or the names of the nominees in which such holder wishes thecertificate or certificates for shares of Common Stock to be issued. If required by the Company, certificates surrendered for conversion shall be endorsed or accompanied by a written instrument or instruments of transfer, in form satisfactory to theCompany, duly executed by the registered holder or his or its attorney duly authorized in writing. The conversion date shall be the date for conversion specified in the Conversion Notice in the case of an Elective Conversion or in any other case onthe date of receipt of such certificates by the transfer agent or the Company following the occurrence of the event (other than an Elective Conversion) giving rise to conversion. The Company shall, as soon as practicable after the conversion date,issue and deliver at such office to such holder, or to his nominees, a certificate or certificates for the number of shares of Common Stock to which such holder shall be entitled, together with cash in lieu of any fraction of a share and, except asprovided in Section 2(c), cash in the amount of any Accrued Dividends (through the date one day prior to the date the shares of Series A Preferred Stock were converted) payable in respect of the shares of Series A Preferred Stock convertedpursuant to this Section 5. 

(ii) The Company shall at all times during which the Series A Preferred Stock shall beoutstanding, reserve and keep available out of its authorized but unissued stock, for the purpose of effecting the conversion of the Series A Preferred Stock, such number of its duly authorized shares of Common Stock as shall from time to time besufficient to effect the conversion of all outstanding Series A Preferred Stock (including any Accrued Dividends). Before taking any action which would cause an adjustment reducing the Conversion Price below the then par value of the shares ofCommon Stock issuable upon conversion of the Series A Preferred Stock, the Company will take any corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue fully paid andnonassessable shares of Common Stock at such adjusted Conversion Price. 

(iii) All shares of Series A Preferred Stock whichshall have been surrendered for conversion as herein provided shall no longer be deemed to be outstanding and all rights with respect to such shares shall immediately cease and terminate on the applicable conversion date, except only the right ofthe holders thereof to receive shares of Common Stock in exchange therefor. Any shares of Series A Preferred Stock so converted shall be retired and cancelled and shall not be reissued, and the Company may from

time to time take such appropriate action as may be necessary to reduce the number of shares of authorized Series A Preferred Stock accordingly. 

(iv) If the conversion is in connection with an underwritten offer of securities registered pursuant to the Act, the conversion may atthe option of any holder tendering Series A Preferred Stock for conversion be conditioned upon the closing with the underwriter of the sale of securities pursuant to such offering, in which event the person(s) entitled to receive the Common Stockissuable upon such conversion of the Series A Preferred Stock shall not be deemed to have converted such Series A Preferred Stock until immediately prior to the closing of the sale of securities. 

(d) *Conversion Price Adjustments of Series A Preferred Stock for Certain Dilutive Issuances, Splits and Combinations*. 

(i) The Conversion Price of the Series A Preferred Stock, as applicable, shall be subject to adjustment from time to time as follows:

(A) If the Company shall issue, after the date upon which any shares of Series A Preferred Stock were first issued (the“Purchase Date”), any Additional Stock (as defined below) without consideration or for a consideration per share less than the Conversion Price for Series A Preferred Stock in effect immediately prior to the issuance of suchAdditional Stock, the Conversion Price for such Series A Preferred Stock in effect immediately prior to each such issuance shall forthwith (except as otherwise provided in this clause (i)) be adjusted to a price determined by multiplying suchConversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including shares of Common Stock deemed to be issued pursuant to subsection 5(d)(i)(E)(1) or(2)) plus the number of shares of Common Stock that the aggregate consideration received by the Company for such issuance would purchase at such Conversion Price; and the denominator of which shall be the number of shares of Common Stockoutstanding immediately prior to such issuance (including shares of Common Stock deemed to be issued pursuant to subsection 5(d)(i)(E)(1) or (2)) plus the number of shares of such Additional Stock; provided, however, for purposes of suchcalculation (1) it shall not include any additional shares of Common Stock issuable with respect to shares of Preferred Stock, convertible securities, or exercisable options, warrants or other rights for the purchase of shares of stock orconvertible securities, solely as a result of the adjustment of such Series A Conversion Price (or other conversion ratios) resulting from the issuance of Additional Stock causing such adjustment and (2) the grant, issue or sale of AdditionalStock consisting of the same class of security, and warrants to purchase such security and notes convertible into such security, issued or issuable at the same price at two or more closings within a six month period shall be aggregated and shall betreated as one sale of Additional Stock occurring on the earliest date on which such securities were granted, issued or sold. 

(B) No adjustment of the Conversion Price for the Series A Preferred Stock shall be made in an amount less than one cent per share,provided that any adjustments that are not required to be made by reason of this sentence shall be carried forward and shall be either taken into account in any subsequent adjustment made prior to three (3) years from the date of the eventgiving rise to the adjustment being carried forward, or shall be made at the end of three (3) years from the date of the event giving rise to the adjustment being carried forward. Except to the limited extent provided for in subsections (E)(3)and (E)(4), no adjustment of such Conversion Price pursuant to this subsection 5(d)(i) shall have the effect of increasing the Conversion Price above the Conversion Price in effect immediately prior to such adjustment. 

(C) In the case of the issuance of Common Stock for cash, the consideration shall be deemed to be the amount of cash paid thereforbefore deducting any discounts, commissions or other expenses allowed, paid or incurred by the Company for any underwriting or otherwise in connection with the issuance and sale thereof. 

(D) In the case of the issuance of the Common Stock for a consideration in whole or in part other than cash, the consideration otherthan cash shall be deemed to be the fair value thereof as determined in good faith by the Board of Directors irrespective of any accounting treatment, taking into consideration the relevant terms of any underlying transaction documents.

(iii) In the event the Company should at any time or from time to time after a Purchase Date fix a record date for the effectuation of asplit or subdivision of the outstanding shares of Common Stock or the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in additional shares of Common Stock or other securities or rightsconvertible into, or entitling the holder thereof to receive directly or indirectly, additional shares of Common Stock (hereinafter referred to as “Common Stock Equivalents”) without payment of any consideration by such holder forthe additional shares of Common Stock or the Common Stock Equivalents (including the additional shares of Common Stock issuable upon conversion or exercise thereof), then, as of such record date (or the date of such dividend distribution, split orsubdivision if no record date is fixed), the Conversion Price of the Series A Preferred Stock shall be appropriately decreased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be increased inproportion to such increase of the aggregate of shares of Common Stock outstanding and those issuable with respect to such Common Stock Equivalents with the number of shares issuable with respect to Common Stock Equivalents determined from time totime in the manner provided for deemed issuances in subsection 5(d)(i)(E). 

(iv) If the number of shares of Common Stockoutstanding at any time after a Purchase Date is decreased by a combination of the outstanding shares of Common Stock, then, following the record date of such combination, the Conversion Price for the Series A Preferred Stock shall be appropriatelyincreased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be decreased in proportion to such decrease in outstanding shares.

(f)*Recapitalizations.* If at any time or from time to time there shall be a recapitalization of the Common Stock (other than a subdivision, combination or merger or sale of assets transaction provided for elsewhere in this Section 5 orSection 3) provision shall be made so that the holders of the Series A Preferred Stock shall thereafter be entitled to receive upon conversion of such Preferred Stock the number of shares of stock or other securities or property of the Companyor otherwise, to which a holder of Common Stock deliverable upon conversion would have been entitled on such recapitalization. In any such case, appropriate adjustment shall be made in the application of the provisions of this Section 5 withrespect to the rights of the holders of such Preferred Stock after the recapitalization to the end that the provisions of this Section 5 (including adjustment of the Conversion Price then in effect and the number of shares purchasable uponconversion of such Preferred Stock) shall be applicable after that event as nearly equivalent as may be practicable.

(h) *No Fractional Shares and Certificate as to Adjustments*. 

(i) No fractional shares shall be issued upon the conversion of any share or shares of theSeries A Preferred Stock, and the number of shares of Common Stock to be issued shall be rounded to the nearest whole share (with one-half being rounded upward). The calculation of the number of shares to be issued shall be determined on the basisof the total number of shares of Series A Preferred Stock the holder is at the time converting into Common Stock and the number of shares of Common Stock issuable upon such aggregate conversion. 

(ii) Upon the occurrence of each adjustment or readjustment of the Conversion Price of Series A Preferred Stock pursuant to thisSection 5, the Company, at its expense, shall promptly compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to each holder of such series of Preferred Stock a certificate setting forth suchadjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Company shall, upon the written request at any time of any holder of Series A Preferred Stock, furnish or cause to be furnished tosuch holder a like certificate setting forth (A) such adjustment and readjustment, (B) the Conversion Price and (C) the number of shares of Common Stock and the amount, if any, of other property that at the time would be received uponthe conversion of a share of Series A Preferred Stock.

(k) *Notices.*Any notice required by the provisions of this Section 5 to be given to the holders of shares of Series APreferred Stock shall be deemed given if deposited in the United States mail, postage prepaid, and addressed to each holder of record at his address appearing on the books of the Company or by electronic transmission in the manner permitted by theGeneral Corporation Law of the State of Delaware.

6. *Redemption of the Preferred Stock*. 

(a) At any time and from time to time on or after February 26, 2014, the Preferred Supermajority may require, by providing writtennotice thereof to the Company (a “Redemption Election”), that all or part of the issued and outstanding shares of Preferred Stock be redeemed by the Company out of funds lawfully available therefor; provided, however, that any suchredemptions shall be for an aggregate Redemption Price, as defined below, of at least $5,000,000. Within fourteen (14) days following the receipt by the Company of a Redemption Election, the Company shall provide written notice to all holdersof Preferred Stock of the Redemption Election (a “Redemption Notice”) which shall set forth the date of such redemption (the “Redemption Date”) and shall allow all other holders of Preferred Stock the opportunity toparticipate in the redemption transaction by providing written notice to the Company (an “Election Notice”) within ten (10) days following the receipt of the Redemption Notice of such holder’s election to participate andthe number and series of shares held by such holder to be redeemed by the Company. The Redemption Date shall be determined by the Company and shall be (i) a date not less than forty-five (45) days and not more than one hundred and eighty(180) days after the date of the Redemption Notice (a “Standard Redemption Date”), or (ii) a date that is more than one hundred and eighty (180) days after the date of the Redemption Election but prior to the datewhich is eighteen months following such date (a “Delayed Redemption Date”). On the applicable Redemption Date, concurrently with surrender by the holders of the certificates representing such shares to be redeemed, the Companyshall, to the extent it may lawfully do so, redeem all issued and outstanding 

shares of Series A Preferred Stock to be redeemed by paying an amount per share therefor equal to (i) in the event such redemption occurs on a Standard Redemption Date, the greater of(A) the Fair Market Value (as defined in Section 6(d) below) per share of Series A Preferred Stock, as of the date of the Redemption Election or (B) the Series A Accreted Value; or (ii) in the event such redemption occurs on aDelayed Redemption Date, the greater of (x) the Fair Market Value per share of Series A Preferred Stock, as of the date which is sixty (60) days prior to the Delayed Redemption Date, or (y) the Series A Accreted Value, (in each case,the “Redemption Price”). Each holder of Preferred Stock to be redeemed shall surrender to the Company the certificate or certificates representing such shares, in the manner and at the place designated in the Redemption Notice, andthereupon the applicable Redemption Price of such shares shall be payable to the order of the person whose name appears on such certificate or certificates as the owner thereof and each surrendered certificate shall be cancelled. In the event lessthan all the shares represented by any such certificate are redeemed, a new certificate shall be issued representing the unredeemed shares. If the Company does not have sufficient funds legally available to redeem on any Redemption Date all sharesof Preferred Stock to be redeemed on such Redemption Date, (i) the Company shall redeem a pro rata portion of each holder’s redeemable shares of Preferred Stock out of funds legally available therefor, based on the respective amounts whichwould otherwise be payable in respect of the shares to be redeemed if the legally available funds were sufficient to redeem all such shares, and shall redeem the remaining shares to have been redeemed as soon as practicable after the Company hasfunds legally available therefore, and (ii) the Company shall use commercially reasonable efforts to obtain sufficient legally available funds in order to effectuate the complete redemption of all shares of Preferred Stock to be redeemed on theRedemption Date as soon as practicable after the Redemption Date. 

(b) In the event the Company sets a Delayed RedemptionDate, upon written notice to the Company not less than thirty (30) days prior to the Delayed Redemption Date, each holder of shares of Preferred Stock electing to redeem shares pursuant to an Election Notice shall have the right, by writtennotice to the Company, to revoke their election to have such shares redeemed. 

(c) From and after a Redemption Date, allrights of the holders of the shares of Preferred Stock designated for redemption as holders of Preferred Stock (except the right to receive the Redemption Price, without interest, upon surrender of their certificate or certificates) shall cease withrespect to such shares, and such shares shall not thereafter be transferred on the books of the Company or be deemed to be outstanding for any purpose whatsoever. The shares of Preferred Stock covered by an Election Notice but not redeemed due tothe Company’s having insufficient funds legally available for redemption thereof shall remain outstanding and entitled to all the rights and preferences provided herein until redeemed as provided in Section 7(a) above. 

(d) For purposes of calculating the Redemption Price, the “Fair Market Value” per share of Series A Preferred Stock,shall be determined in good faith by the Board of Directors (other than those directors affiliated with or nominated by any holder of Preferred Stock that has submitted an Election Notice) as of the applicable date and in making such determinationit shall not give consideration to any discount related to shares representing minority interest or related to any illiquidity or lack of marketability of shares arising from restrictions on transfer under applicable federal or state securitieslaws, but shall take into consideration the rights and preferences of the Preferred Stock. If the holders of a majority of the Preferred Stock to be redeemed disagree with such determination of Fair Market Value, such holders shall provide writtennotice to the Company thereof (a “Value Dispute”) and the Fair Market Value per share of the Series A Preferred Stock, shall be determined by the following procedures. Each of the Company, on the one hand, and the holders of SeriesA Preferred Stock submitting the Value Dispute, on the other hand, shall appoint an independent appraiser, each of whom shall independently determine the Fair Market Value per share of Series A Preferred Stock (the “AppraisedValues”). If the higher of the Appraised Values is not more than 25% higher than the lower of the Appraised Values, then the Fair Market Value per share will be the average of the two Appraised Values. If the higher of the Appraised Valuesis more than 25% higher than the lower of the Appraised Values, then the parties shall appoint a third independent appraiser who shall, within thirty (30) days following receipt of the Appraised Values, select one of the two Appraised Values asthe Fair Market Value per share which is closest to the Fair Market Value per share determined by such third party appraiser (the “Third Party Determination”). The Third Party Determination shall be binding on and non-appealable bythe Company and the holders of the shares of Preferred Stock to be redeemed. Following the receipt of the Third Party Determination, the Redemption Date shall be deemed to be the date which is ten (10) days thereafter. All costs of theappraisers pursuant to this Section 6(d) shall be split equally by the Company on the one hand and the holders of Preferred Stock to be redeemed on the other hand. 

7. *Sinking Fund*. 

There shall be no sinking fund for the payment ofdividends, or liquidation preferences on the Series A Preferred Stock or the redemption of any shares thereof. 

8.*Amendment*. 

This Certificate of Designation constitutes an agreement between the Company and the holders of the Series APreferred Stock. It may be amended by vote of the Board of Directors of the Company and the written consent of the Preferred Supermajority; 

*provided, however*, that nothing in this Section 8 shall be deemed to alter any statutory provision entitling a particular class or series of shares to vote as a class or series withrespect to such amendment; *provided further, however*, any such amendment that would have a material adverse effect on the rights of a particular holder of shares of Preferred Stock provided in this Certificate of Designation, but would nothave a similar material adverse effect on all holders of Preferred Stock generally, shall require the consent of such materially adversely affected holder.
