RIOT BLOCKCHAIN, INC.

I, Jeffrey McGonegal, hereby certify that I am the Chief Financial Officer of Riot Blockchain, Inc. (the “Company”), a corporation organized and existing under the Nevada Revised Statutes (the “NRS”), and further do hereby certify:

That pursuant to the authority expressly conferred upon the Board of Directors of the Company (the “Board”) by the Company’s Articles of Incorporation, as amended (the “Articles of Incorporation”), the Board on November 1, 2017 adopted the following resolutions creating a series of shares of Preferred Stock designated as 0% Series B Convertible Preferred Stock, none of which shares has been issued:

RESOLVED, that the Board designates the 0% Series B Convertible Preferred Stock and the number of shares constituting such series, and fixes the rights, powers, preferences, privileges and restrictions relating to such series in addition to any set forth in the Articles of Incorporation as follows:

TERMS OF SERIES B CONVERTIBLE PREFERRED STOCK

1. Designation and Number of Shares. There shall hereby be created and established by this Certificate of Designation of Rights, Powers, Preferences, Privileges and Restrictions (this “Certificate of Designation”) a series of preferred stock of the Company designated as “0% Series B Convertible Preferred Stock” (the “Preferred Shares”). The authorized number of Preferred Shares shall be One Million Seven Hundred Fifty Thousand and One (1,750,001) shares. Each Preferred Share shall have no par value. Capitalized terms not defined herein shall have the meaning as set forth in Section 23 below.

2. Ranking. Except to the extent that the holders of at least a majority of the outstanding Preferred Shares (the “Required Holders”) expressly consent to the creation of Parity Stock (as defined below) or Senior Preferred Stock (as defined below) in accordance with Section 12, all shares of capital stock of the Company shall be junior in rank to all Preferred Shares with respect to the preferences as to dividends, distributions and payments upon the liquidation, dissolution and winding up of the Company (such junior stock is referred to herein collectively as “Junior Stock”)(except for the avoidance of doubt, with respect to the Company’s Series A Convertible Preferred Stock). The rights of all such shares of capital stock of the Company shall be subject to the rights, powers, preferences and privileges of the Preferred Shares. Without limiting any other provision of this Certificate of Designations, without the prior express consent of the Required Holders, voting separately as a single class, the Company shall not hereafter authorize or issue any additional or other shares of capital stock that is (i) of senior rank to the Preferred Shares in respect of the preferences as to dividends, distributions and payments upon the liquidation, dissolution and winding up of the Company (collectively, the “Senior Preferred Stock”), (ii) of pari passu rank to the Preferred Shares in respect of the preferences as to dividends, distributions and payments upon the liquidation, dissolution and winding up of the Company (collectively, the “Parity Stock”) or (iii) any Junior Stock having a maturity date (or any other date requiring redemption or repayment of such shares of Junior Stock) that is prior to the date no Preferred Shares remain outstanding. In the event of the merger or consolidation of the Company with or into another corporation, the Preferred Shares shall maintain their relative rights, powers, designations, privileges and preferences provided for herein and no such merger or consolidation shall result inconsistent therewith.

3. Dividends. In addition to Sections 5(a) and 11 below, from and after the first date of issuance of any Preferred Shares (the “Initial Issuance Date”), each holder of a Preferred Share (each, a “Holder” and collectively, the “Holders”) shall be entitled to receive dividends (“Dividends”) when and as declared by the Board, from time to time, in its sole discretion, which Dividends shall be paid by the Company out of funds legally available therefor, payable, subject to the conditions and other terms hereof, in cash on the Stated Value of such Preferred Share.

4. Conversion. Each Preferred Share shall be convertible into validly issued, fully paid and non-assessable shares of Common Stock, no par value per share (the “Common Stock”) on the terms and conditions set forth in this Section 4.

(a) Holder’s Conversion Right. Subject to the provisions of Section 4(e) and 4(f), at any time or times on or after the Initial Issuance Date, each Holder shall be entitled to convert any whole number of Preferred Shares into validly issued, fully paid and non-assessable shares of Common Stock in accordance with Section 4(c) at the Conversion Rate (as defined below).

(b) Conversion Rate. The number of validly issued, fully paid and non-assessable shares of Common Stock issuable upon conversion of each Preferred Share pursuant to Section 4(a) shall be determined according to the following formula (the “Conversion Rate”):

Base Amount

Conversion Price

No fractional shares of Common Stock are to be issued upon the conversion of any Preferred Shares. If the issuance would result in the issuance of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock up to the nearest whole share.

(i) Holder’s Conversion. To convert a Preferred Share into validly issued, fully paid and non-assessable shares of Common Stock on any date (a “Conversion Date”), a Holder shall deliver (whether via facsimile or otherwise), for receipt on or prior to 11:59 p.m., New York time, on such date, a copy of an executed notice of conversion of the share(s) of Preferred Shares subject to such conversion in the form attached hereto as Exhibit I (the “Conversion Notice”) to the Company. If required by Section 4(c)(vi), within five (5) Trading Days following a conversion of any such Preferred Shares as aforesaid, such Holder shall surrender to a nationally recognized overnight delivery service for delivery to the Company the original certificates representing the share(s) of Preferred Shares (the “Preferred Share Certificates”) so converted as aforesaid.

(ii) Company’s Response. On or before the first (1st) Trading Day following the date of receipt of a Conversion Notice, the Company shall transmit by facsimile, or if requested by Holder, by email, an acknowledgment of confirmation, in the form attached hereto as Exhibit II, of receipt of such Conversion Notice to such Holder and the transfer agent, which confirmation shall constitute an instruction to the transfer agent to process such Conversion Notice in accordance with the terms herein. On or before the second (2nd) Trading Day following the date of receipt by the Company of such Conversion Notice, the Company shall (1) provided that the transfer agent is participating in DTC Fast Automated Securities Transfer Program, credit such aggregate number of shares of Common Stock to which such Holder shall be entitled to such Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system, or (2) if the transfer agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver (via reputable overnight courier) to the address as specified in such Conversion Notice, a certificate, registered in the name of such Holder or its designee, for the number of shares of Common Stock to which such Holder shall be entitled. If the number of Preferred Shares represented by the Preferred Share Certificate(s) submitted for conversion pursuant to Section 4(c)(vi) is greater than the number of Preferred Shares being converted, then the Company shall if requested by such Holder, as soon as practicable and in no event later than two (2) Trading Days after receipt of the Preferred Share Certificate(s) and at its own expense, issue and deliver to such Holder (or its designee) a new Preferred Share Certificate representing the number of Preferred Shares not converted.

(iii) Record Holder. The Person or Persons entitled to receive the shares of Common Stock issuable upon a conversion of Preferred Shares shall be treated for all purposes as the record holder or holders of such shares of Common Stock on the Conversion Date.

(iv) Company’s Failure to Timely Convert. If the Company shall fail, for any reason or for no reason, except in the case that the relevant Preferred Share Certificate is required to be and shall not have been timely received by the transfer agent, to issue to a Holder within two (2) Trading Days after the Company’s receipt of a Conversion Notice (whether via facsimile or otherwise) (the “Share Delivery Deadline”), a certificate for the number of shares of Common Stock to which such Holder is entitled and register such shares of Common Stock on the Company’s share register or to credit such Holder’s or its designee’s balance account with DTC for such number of shares of Common Stock to which such Holder is entitled upon such Holder’s conversion of any Preferred Shares (as the case may be) (a “Conversion Failure”), then, in addition to all other remedies available to such Holder, such Holder, upon written notice to the Company, (x) may void its Conversion Notice with respect to, and retain or have returned (as the case may be) any Preferred Shares that have not been converted pursuant to such Holder’s Conversion Notice, provided that the voiding of a Conversion Notice shall not affect the Company’s obligations to make any payments which have accrued prior to the date of such notice pursuant to the terms of this Certificate of Designations or otherwise and (y) the Company shall pay in cash to such Holder on each day after such third (3rd) Trading Day that the issuance of such shares of Common Stock is not timely effected an amount equal to 1.5% of the product of (A) the aggregate number of shares of Common Stock not issued to such Holder on a timely basis and to which the Holder is entitled and (B) the Closing Sale Price of the Common Stock on the Trading Day immediately preceding the last possible date on which the Company could have issued such shares of Common Stock to the Holder without violating Section 4(c). In addition to the foregoing, if within two (2) Trading Days after the Company’s receipt of a Conversion Notice (whether via facsimile or otherwise), the Company shall fail to issue and deliver a certificate to such Holder and register such shares of Common Stock on the Company’s share register or credit such Holder’s or its designee’s balance account with DTC for the number of shares of Common Stock to which such Holder is entitled upon such Holder’s conversion hereunder (as the case may be), and if on or after such third (3rd) Trading Day such Holder (or any other Person in respect, or on behalf, of such Holder) purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by such Holder of all or any portion of the number of shares of Common Stock, or a sale of a number of shares of Common Stock equal to all or any portion of the number of shares of Common Stock, issuable upon such conversion that such Holder so anticipated receiving from the Company, then, in addition to all other remedies available to such Holder, the Company shall, within two (2) Business Days after such Holder’s request and in such Holder’s discretion, either (i) pay cash to such Holder in an amount equal to such Holder’s total purchase price (including brokerage commissions and other out-of-pocket expenses, if any) for the shares of Common Stock so purchased (including, without limitation, by any other Person in respect, or on behalf, of such Holder) (the “Buy-In Price”), at which point the Company’s obligation to so issue and deliver such certificate or credit such Holder’s balance account with DTC for the number of shares of Common Stock to which such Holder is entitled upon such Holder’s conversion hereunder (as the case may be) (and to issue such shares of Common Stock) shall terminate, or (ii) promptly honor its obligation to so issue and deliver to such Holder a certificate or certificates representing such shares of Common Stock or credit such Holder’s balance account with DTC for the number of shares of Common Stock to which such Holder is entitled upon such Holder’s conversion hereunder (as the case may be) and pay cash to such Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock multiplied by (B) the lowest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the date of the applicable Conversion Notice and ending on the date of such issuance and payment under this clause (ii).

(v) Pro Rata Conversion; Disputes. In the event the Company receives a Conversion Notice from more than one Holder for the same Conversion Date and the Company can convert some, but not all, of such Preferred Shares submitted for conversion, the Company shall convert from each Holder electing to have Preferred Shares converted on such date a pro rata amount of such Holder’s Preferred Shares submitted for conversion on such date based on the number of Preferred Shares submitted for conversion on such date by such Holder relative to the aggregate number of Preferred Shares submitted for conversion on such date. In the event of a dispute as to the number of shares of Common Stock issuable to a Holder in connection with a conversion of Preferred Shares, the Company shall issue to such Holder the number of shares of Common Stock not in dispute and resolve such dispute in accordance with Section 22.

(vi) Book-Entry. Notwithstanding anything to the contrary set forth in this Section 4, upon conversion of any Preferred Shares in accordance with the terms hereof, no Holder thereof shall be required to physically surrender the certificate representing the Preferred Shares to the Company following conversion thereof unless (A) the full or remaining number of Preferred Shares represented by the certificate are being converted (in which event such certificate(s) shall be delivered to the Company as contemplated by this Section 4(c)(vi)) or (B) such Holder has provided the Company with prior written notice (which notice may be included in a Conversion Notice) requesting reissuance of Preferred Shares upon physical surrender of any Preferred Shares. Each Holder and the Company shall maintain records showing the number of Preferred Shares so converted by such Holder and the dates of such conversions or shall use such other method, reasonably satisfactory to such Holder and the Company, so as not to require physical surrender of the certificate representing the Preferred Shares upon each such conversion. In the event of any dispute or discrepancy, such records of such Company establishing the number of Preferred Shares to which the record holder is entitled shall be controlling and determinative in the absence of manifest error. A Holder and any transferee or assignee, by acceptance of a certificate, acknowledge and agree that, by reason of the provisions of this paragraph, following conversion of any Preferred Shares, the number of Preferred Shares represented by such certificate may be less than the number of Preferred Shares stated on the face thereof. Each certificate for Preferred Shares shall bear the following legend:

ANY TRANSFEREE OR ASSIGNEE OF THIS CERTIFICATE SHOULD CAREFULLY REVIEW THE TERMS OF THE CORPORATION’S CERTIFICATE OF DESIGNATIONS RELATING TO THE SHARES OF SERIES B PREFERRED STOCK REPRESENTED BY THIS CERTIFICATE, INCLUDING SECTION 4(c)(vi) THEREOF. THE NUMBER OF SHARES OF SERIES B PREFERRED STOCK REPRESENTED BY THIS CERTIFICATE MAY BE LESS THAN THE NUMBER OF SHARES OF SERIES B PREFERRED STOCK STATED ON THE FACE HEREOF PURSUANT TO SECTION 4(c)(vi) OF THE CERTIFICATE OF DESIGNATIONS RELATING TO THE SHARES OF SERIES B PREFERRED STOCK REPRESENTED BY THIS CERTIFICATE.

(d) Taxes. The Company shall pay any and all documentary, stamp, transfer (but only in respect of the registered holder thereof), issuance and other similar taxes that may be payable with respect to the issuance and delivery of shares of Common Stock upon the conversion of Preferred Shares.

(e) Limitation on Beneficial Ownership. Notwithstanding anything to the contrary set forth in this Certificate of Designation, at no time may all or a portion of the Series B Preferred Stock be converted if the number of shares of Common Stock to be issued pursuant to such conversion would exceed, when aggregated with all other shares of Common Stock owned by the Holder at such time, the number of shares of Common Stock which would result in the Holder beneficially owning (as determined in accordance with Section 13(d) of the 1934 Act and the rules thereunder) more than 4.99% of all of the Common Stock outstanding at such time (the “4.99% Beneficial Ownership Limitation”); provided, however, that upon the Holder providing the Corporation with sixty-one (61) days’ advance notice (the “4.99% Waiver Notice”) that the Holder would like to waive this Section 4(e) with regard to any or all shares of Common Stock issuable upon conversion of the Preferred Shares, this Section 4(e) will be of no force or effect with regard to all or a portion of the Series B Preferred Stock referenced in the 4.99% Waiver Notice but shall in no event waive the 9.99% Beneficial Ownership Limitation described below. Notwithstanding anything to the contrary set forth in this Certificate of Designation, at no time may all or a portion of the Preferred Shares be converted if the number of shares of Common Stock to be issued pursuant to such conversion, when aggregated with all other shares of Common Stock owned by the Holder at such time, would result in the Holder beneficially owning (as determined in accordance with Section 13(d) of the 1934 Act and the rules thereunder) in excess of 9.99% of the then issued and outstanding shares of Common Stock outstanding at such time (the “9.99% Beneficial Ownership Limitation” and the lower of the 9.99% Beneficial Ownership Limitation and the 4.99% Beneficial Ownership Limitation then in effect, the “Maximum Percentage”). By written notice to the Company, a holder of Preferred Shares may from time to time decrease the Maximum Percentage to any other percentage specified in such notice. For purposes hereof, in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other public filing with the Securities and Exchange Commission, as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written or oral request of a holder of Preferred Shares, the Company shall within two (2) Business Days confirm orally and in writing to such holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including the Preferred Shares, by the Holder and its Affiliates since the date as of which such number of outstanding shares of Common Stock was reported, which in any event are convertible or exercisable, as the case may be, into shares of the Company’s Common Stock within 60 days’ of such calculation and which are not subject to a limitation on conversion or exercise analogous to the limitation contained herein. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 4(e) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation.

(f) Issuance Restrictions. If the Company has not obtained the approval of its shareholders in accordance with NASDAQ Listing Rule 5635(d), then the Company may not issue upon conversion of the Preferred Shares a number of shares of Common Stock, which, when aggregated with any other shares of Common Stock underlying the Preferred Shares issued pursuant to the Exchange Agreement would exceed 19.99% of the shares of Common Stock issued and outstanding as of the Effective Date, subject to adjustment for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock that occur after the date of the Exchange Agreement (such number of shares, the “Issuable Maximum”). The Holder and the holders of the other Preferred Shares issued pursuant to the Exchange Agreement shall be entitled to a portion of the Issuable Maximum equal to the quotient obtained by dividing (x) the amount of the Holder’s Preferred Shares by (y) the aggregate Preferred Shares issued to all holders pursuant to the Exchange Agreement. In addition, the Holder may allocate its pro-rata portion of the Issuable Maximum among Preferred Shares held by it in its sole discretion. Such portion shall be adjusted upward ratably in the event a Holder no longer holds any Preferred Shares and the amount of shares issued to such Holder pursuant to its Preferred Shares was less than such Holder’s pro-rata share of the Issuable Maximum.

5. Rights Upon Issuance of Purchase Rights and Other Corporate Events.

(a) Purchase Rights. In addition to any adjustments pursuant to Section 7 below, if at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of Common Stock (the “Purchase Rights”), then each Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which such Holder could have acquired if such Holder had held the number of shares of Common Stock acquirable upon complete conversion of all the Preferred Shares (without taking into account any limitations or restrictions on the convertibility of the Preferred Shares) held by such Holder immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, to the extent that such Holder’s right to participate in any such Purchase Right would result in such Holder exceeding the Maximum Percentage, then such Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for such Holder until such time, if ever, as its right thereto would not result in such Holder exceeding the Maximum Percentage).

(b) Other Corporate Events. In addition to and not in substitution for any other rights hereunder, prior to the consummation of any Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make appropriate provision to insure that each Holder will thereafter have the right to receive upon a conversion of all the Preferred Shares held by such Holder (i) in addition to the shares of Common Stock receivable upon such conversion, such securities or other assets to which such Holder would have been entitled with respect to such shares of Common Stock had such shares of Common Stock been held by such Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions on the convertibility of the Preferred Shares contained in this Certificate of Designations) or (ii) in lieu of the shares of Common Stock otherwise receivable upon such conversion, such securities or other assets received by the holders of shares of Common Stock in connection with the consummation of such Corporate Event in such amounts as such Holder would have been entitled to receive had the Preferred Shares held by such Holder initially been issued with conversion rights for the form of such consideration (as opposed to shares of Common Stock) at a conversion rate for such consideration commensurate with the Conversion Rate. The provisions of this Section 5(b) shall apply similarly and equally to successive Corporate Events and shall be applied without regard to any limitations on the conversion of the Preferred Shares contained in this Certificate of Designations.

6. Rights Upon Fundamental Transactions.

(a) Assumption. The Company shall not enter into or be party to a Fundamental Transaction unless (i) the Successor Entity assumes in writing all of the obligations of the Company under this Certificate of Designations and the Exchange Agreement in accordance with the provisions of this Section 6 pursuant to written agreements in form and substance satisfactory to the Required Holders and approved by the Required Holders prior to such Fundamental Transaction, including agreements to deliver to each holder of Preferred Shares in exchange for such Preferred Shares a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Certificate of Designations, including, without limitation, having a stated value and dividend rate equal to the stated value and dividend rate of the Preferred Shares held by the Holders and having similar ranking to the Preferred Shares, and reasonably satisfactory to the Required Holders and (ii) the Successor Entity (including its Parent Entity) is a publicly traded corporation whose shares of common stock are quoted on or listed for trading on an Eligible Market. Upon the occurrence of any Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Certificate of Designations and the Exchange Agreement referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Certificate of Designations and the Exchange Agreement with the same effect as if such Successor Entity had been named as the Company herein and therein. In addition to the foregoing, upon consummation of a Fundamental Transaction, the Successor Entity shall deliver to each Holder confirmation that there shall be issued upon conversion of the Preferred Shares at any time after the consummation of such Fundamental Transaction, in lieu of the shares of Common Stock (or other securities, cash, assets or other property (except such items still issuable under Sections 5 and 11, which shall continue to be receivable thereafter)) issuable upon the conversion of the Preferred Shares prior to such Fundamental Transaction, such shares of publicly traded common stock (or their equivalent) of the Successor Entity (including its Parent Entity) which each Holder would have been entitled to receive upon the happening of such Fundamental Transaction had all the Preferred Shares held by each Holder been converted immediately prior to such Fundamental Transaction (without regard to any limitations on the conversion of the Preferred Shares contained in this Certificate of Designations), as adjusted in accordance with the provisions of this Certificate of Designations. The provisions of this Section 6 shall apply similarly and equally to successive Fundamental Transactions and shall be applied without regard to any limitations on the conversion of the Preferred Shares.

7. Rights Upon Issuance of Other Securities.

(a) Intentionally Omitted.

(b) Adjustment of Conversion Price upon Subdivision or Combination of Common Stock. Without limiting any provision of Sections 5 and 11, if the Company at any time on or after the Effective Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced. Without limiting any provision of Sections 5 and 11, if the Company at any time on or after the Effective Date combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Conversion Price in effect immediately prior to such combination will be proportionately increased. Any adjustment pursuant to this Section 7(b) shall become effective immediately after the effective date of such subdivision or combination. If any event requiring an adjustment under this Section 7(b) occurs during the period that a Conversion Price is calculated hereunder, then the calculation of such Conversion Price shall be adjusted appropriately to reflect such event.

(c) Other Events. In the event that the Company (or any Subsidiary) shall take any action to which the provisions hereof are not strictly applicable, or, if applicable, would not operate to protect any Holder from dilution or if any event occurs of the type contemplated by the provisions of this Section 7 but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features), then the Board shall in good faith determine and implement an appropriate adjustment in the Conversion Price so as to protect the rights of such Holder, provided that no such adjustment pursuant to this Section 7(c) will increase the Conversion Price as otherwise determined pursuant to this Section 7, provided further that if such Holder does not accept such adjustments as appropriately protecting its interests hereunder against such dilution, then the Board and such Holder shall agree, in good faith, upon an independent investment bank of nationally recognized standing to make such appropriate adjustments, whose determination shall be final and binding and whose fees and expenses shall be borne by the Company.

(d) Calculations. All calculations under this Section 7 shall be made by rounding to the nearest one-hundred thousandth of a cent or the nearest 1/100th of a share, as applicable. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company, and the disposition of any such shares, other than a return thereof to the Company’s treasury for cancellation, shall be considered an issue or sale of Common Stock.

8. Authorized Shares.

(a) Reservation. The Company shall initially reserve out of its authorized and unissued Common Stock a number of shares of Common Stock equal to 100% of the Conversion Rate with respect to the Base Amount of each Preferred Share as of the Initial Issuance Date (assuming for purposes hereof, that all the Preferred Shares issuable pursuant to the Exchange Agreement have been issued, such Preferred Shares are convertible at the Conversion Price and without taking into account any limitations on the conversion of such Preferred Shares set forth in herein) issuable pursuant to the terms of this Certificate of Designations from the Initial Issuance Date through the second anniversary of the Initial Issuance Date assuming (assuming for purposes hereof, that all the Preferred Shares issuable pursuant to the Exchange Agreement have been issued and without taking into account any limitations on the issuance of securities set forth herein). So long as any of the Preferred Shares are outstanding, the Company shall take all action necessary to reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose of effecting the conversion of the Preferred Shares, as of any given date, 100% of the number of shares of Common Stock as shall from time to time be necessary to effect the conversion of all of the Preferred Shares issued or issuable pursuant to the Exchange Agreement assuming for purposes hereof, that all the Preferred Shares issuable pursuant to the Exchange Agreement have been issued and without taking into account any limitations on the issuance of securities set forth herein), provided that at no time shall the number of shares of Common Stock so available be less than the number of shares required to be reserved by the previous sentence (without regard to any limitations on conversions contained in this Certificate of Designations) (the “Required Amount”). The initial number of shares of Common Stock reserved for conversions of the Preferred Shares and each increase in the number of shares so reserved shall be allocated pro rata among the Holders based on the number of Preferred Shares held by each Holder on the Initial Issuance Date or increase in the number of reserved shares (as the case may be) (the “Authorized Share Allocation”). In the event a Holder shall sell or otherwise transfer any of such Holder’s Preferred Shares, each transferee shall be allocated a pro rata portion of such Holder’s Authorized Share Allocation. Any shares of Common Stock reserved and allocated to any Person which ceases to hold any Preferred Shares shall be allocated to the remaining Holders of Preferred Shares, pro rata based on the number of Preferred Shares then held by such Holders.

(b) Insufficient Authorized Shares. If, notwithstanding Section 8(a) and not in limitation thereof, at any time while any of the Preferred Shares remain outstanding the Company does not have a sufficient number of authorized and unissued shares of Common Stock to satisfy its obligation to have available for issuance upon conversion of the Preferred Shares at least a number of shares of Common Stock equal to the Required Amount (an “Authorized Share Failure”), then the Company shall promptly take all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve and have available the Required Amount for all of the Preferred Shares then outstanding. Without limiting the generality of the foregoing sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than ninety (90) days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its shareholders or conduct a consent solicitation for the approval of an increase in the number of authorized shares of Common Stock. In connection with such meeting or consent solicitation, the Company shall provide each shareholder with a proxy statement or information statement, as relevant, and shall use its commercial best efforts to solicit its shareholders’ approval of such increase in authorized shares of Common Stock and to cause its Board to recommend to the shareholders that they approve such proposal. Nothing contained in this Section 8 shall limit any obligations of the Company under any provision of the Exchange Agreement.

9. Voting Rights. Except as otherwise expressly required by law, each holder of Preferred Shares shall be entitled to vote on all matters submitted to shareholders of the Company and shall be entitled to the number of votes for each Preferred Share owned at the record date for the determination of shareholders entitled to vote on such matter or, if no such record date is established, at the date such vote is taken or any written consent of shareholders is solicited, equal to the number of shares of Common Stock such Preferred Shares are convertible into (voting as a class with Common Stock), but not in excess of the conversion limitations set forth in Section 4(e) and/or 4(f) herein. Except as otherwise required by law, the holders of Preferred Shares shall vote together with the holders of Common Stock on all matters and shall not vote as a separate class.

10. Liquidation, Dissolution, Winding-Up. In the event of a Liquidation Event, the Holders shall be entitled to receive in cash out of the assets of the Company, whether from capital or from earnings available for distribution to its shareholders (the “Liquidation Funds”), before any amount shall be paid to the holders of any of shares of Junior Stock, an amount per Preferred Share equal to the greater of (A) the Base Amount thereof on the date of such payment and (B) the amount per share such Holder would receive if such Holder converted such Preferred Shares into Common Stock immediately prior to the date of such payment, provided that if the Liquidation Funds are insufficient to pay the full amount due to the Holders and holders of shares of Parity Stock, then each Holder and each holder of Parity Stock shall receive a percentage of the Liquidation Funds equal to the full amount of Liquidation Funds payable to such Holder and such holder of Parity Stock as a liquidation preference, in accordance with their respective certificate of designations (or equivalent), as a percentage of the full amount of Liquidation Funds payable to all holders of Preferred Shares and all holders of shares of Parity Stock. To the extent necessary, the Company shall cause such actions to be taken by each of its subsidiaries so as to enable, to the maximum extent permitted by law, the proceeds of a Liquidation Event to be distributed to the Holders in accordance with this Section 10. All the preferential amounts to be paid to the Holders under this Section 10 shall be paid or set apart for payment before the payment or setting apart for payment of any amount for, or the distribution of any Liquidation Funds of the Company to the holders of shares of Junior Stock in connection with a Liquidation Event as to which this Section 10 applies.

11. Participation. In addition to any adjustments pursuant to Section 7(b), the Holders shall, as holders of Preferred Shares, be entitled to receive such dividends paid and distributions made to the holders of shares of Common Stock to the same extent as if such Holders had converted each Preferred Share held by each of them into shares of Common Stock (without regard to any limitations on conversion herein or elsewhere) and had held such shares of Common Stock on the record date for such dividends and distributions. Payments under the preceding sentence shall be made concurrently with the dividend or distribution to the holders of shares of Common Stock (provided, however, to the extent that a Holder’s right to participate in any such dividend or distribution would result in such Holder exceeding the Maximum Percentage, then such Holder shall not be entitled to participate in such dividend or distribution to such extent (or the beneficial ownership of any such shares of Common Stock as a result of such dividend or distribution to such extent) and such dividend or distribution to such extent shall be held in abeyance for the benefit of such Holder until such time, if ever, as its right thereto would not result in such Holder exceeding the Maximum Percentage).

12. Vote to Change the Terms of Preferred Shares. In addition to any other rights provided by law, except where the vote or written consent of the holders of a greater number of shares is required by law or by another provision of the Articles of Incorporation, without first obtaining the affirmative vote at a meeting duly called for such purpose or the written consent without a meeting of the Required Holders, voting together as a single class, the Company shall not: (a) amend or repeal any provision of, or add any provision to, its Articles of Incorporation or bylaws, or file any certificate of designations or articles of amendment of any series of shares of preferred stock, if such action would adversely alter or change in any respect the preferences, rights, privileges or powers, or restrictions provided for the benefit, of the Preferred Shares, regardless of whether any such action shall be by means of amendment to the Articles of Incorporation or by merger, consolidation or otherwise; (b) increase or decrease (other than by conversion) the authorized number of Preferred Shares; (c) purchase, repurchase or redeem any shares of capital stock of the Company junior in rank to the Preferred Shares (other than pursuant to equity incentive agreements (that have in good faith been approved by the Board) with employees giving the Company the right to repurchase shares upon the termination of services); (d) without limiting any provision of Section 2, pay dividends or make any other distribution on any shares of any capital stock of the Company junior in rank to the Preferred Shares; or (e) without limiting any provision of Section 16, whether or not prohibited by the terms of the Preferred Shares, circumvent a right of the Preferred Shares.

13. Intentionally Omitted.

14. Lost or Stolen Certificates. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of any certificates representing Preferred Shares (as to which a written certification and the indemnification contemplated below shall suffice as such evidence), and, in the case of loss, theft or destruction, of an indemnification undertaking by the applicable Holder to the Company in customary and reasonable form and, in the case of mutilation, upon surrender and cancellation of the certificate(s), the Company shall execute and deliver new certificate(s) of like tenor and date.

15. Remedies, Characterizations, Other Obligations, Breaches and Injunctive Relief. The remedies provided in this Certificate of Designations shall be cumulative and in addition to all other remedies available under this Certificate of Designations and the Exchange Agreement, at law or in equity (including a decree of specific performance and/or other injunctive relief), and no remedy contained herein shall be deemed a waiver of compliance with the provisions giving rise to such remedy. Nothing herein shall limit any Holder’s right to pursue actual and consequential damages for any failure by the Company to comply with the terms of this Certificate of Designations. The Company covenants to each Holder that there shall be no characterization concerning this instrument other than as expressly provided herein. 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 a Holder 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 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, each Holder shall be entitled, in addition to all other available remedies, to an injunction restraining any such breach or any such threatened breach, without the necessity of showing economic loss and without any bond or other security being required. The Company shall provide all information and documentation to a Holder that is requested by such Holder to enable such Holder to confirm the Company’s compliance with the terms and conditions of this Certificate of Designations.

16. Noncircumvention. The Company hereby covenants and agrees that the Company will not, by amendment of its Articles of Incorporation, bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, 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 of this Certificate of Designations, and will at all times in good faith carry out all the provisions of this Certificate of Designations and take all action as may be required to protect the rights of the Holders. Without limiting the generality of the foregoing or any other provision of this Certificate of Designations, the Company (i) shall not increase the par value of any shares of Common Stock receivable upon the conversion of any Preferred Shares above the Conversion Price then in effect, (ii) shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable shares of Common Stock upon the conversion of Preferred Shares and (iii) shall, so long as any Preferred Shares are outstanding, take all action necessary to reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose of effecting the conversion of the Preferred Shares, the maximum number of shares of Common Stock as shall from time to time be necessary to effect the conversion of the Preferred Shares then outstanding (without regard to any limitations on conversion contained herein).

17. Failure or Indulgence Not Waiver. No failure or delay on the part of a Holder 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. No waiver shall be effective unless it is in writing and signed by an authorized representative of the waiving party. This Certificate of Designations shall be deemed to be jointly drafted by the Company and all Holders and shall not be construed against any Person as the drafter hereof.

18. Notices. The Company shall provide each Holder of Preferred Shares with prompt written notice of all actions taken pursuant to the terms of this Certificate of Designations, including in reasonable detail a description of such action and the reason therefor. Whenever notice is required to be given under this Certificate of Designations, unless otherwise provided herein, such notice must be in writing and shall be given in accordance with the Exchange Agreement. Without limiting the generality of the foregoing, the Company shall give written notice to each Holder (i) promptly following any adjustment of the Conversion Price, setting forth in reasonable detail, and certifying, the calculation of such adjustment and (ii) at least fifteen (15) days prior to the date on which the Company closes its books or takes a record (A) with respect to any dividend or distribution upon the Common Stock, (B) with respect to any grant, issuances, or sales of any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property to all holders of shares of Common Stock as a class or (C) for determining rights to vote with respect to any Fundamental Transaction, dissolution or liquidation, provided, in each case, that such information shall be made known to the public prior to, or simultaneously with, such notice being provided to any Holder.

19. Transfer of Preferred Shares. Subject to the restrictions set forth in Exchange Agreement, a Holder may transfer some or all of its Preferred Shares without the consent of the Company.

20. Preferred Shares Register. The Company shall maintain at its principal executive offices (or such other office or agency of the Company as it may designate by notice to the Holders), a register for the Preferred Shares, in which the Company shall record the name, address and facsimile number of the Persons in whose name the Preferred Shares have been issued, as well as the name, address, facsimile number and tax identification number of each transferee. The Company may treat the Person in whose name any Preferred Shares is registered on the register as the owner and holder thereof for all purposes, notwithstanding any notice to the contrary, but in all events recognizing any properly made transfers.

21. Shareholder Matters; Amendment.

(a) Shareholder Matters. Any shareholder action, approval or consent required, desired or otherwise sought by the Company pursuant to the NRS, the Articles of Incorporation, this Certificate of Designations or otherwise with respect to the issuance of Preferred Shares may be effected by written consent of the Company’s shareholders or at a duly called meeting of the Company’s shareholders, all in accordance with the applicable rules and regulations of the NRS, the Company’s Articles of Incorporation and Bylaws. This provision is intended to comply with the applicable sections of the NRS permitting shareholder action, approval and consent affected by written consent in lieu of a meeting.

(b) Amendment. This Certificate of Designations or any provision hereof may be amended by obtaining the affirmative vote at a meeting duly called for such purpose, or written consent without a meeting in accordance with the NRS, of the Required Holders, voting separate as a single class, and with such other shareholder approval, if any, as may then be required pursuant to the NRS and the Company’s Articles of Incorporation and Bylaws.
