Certificate of Determination shall be filed to reflect the revised terms;

thereafter have the right to acquire and receive in lieu of or in addition to (as the case may be) the shares of Common Stock immediately theretofore acquirable and receivable upon the conversion of such Holders Series A Preferred Shares, such
shares of stock, securities or assets as may be issued or payable with respect to or in exchange for the number of shares of Common Stock immediately theretofore acquirable and receivable upon the conversion of such Holders Series A Preferred
Shares had such Organic Change not taken place. In any such case, the Company will make appropriate provision (in form and substance satisfactory to a majority of the Holders) with respect to such Holders rights and interests to insure that
the provisions of Section 2(d) below will thereafter be applicable to the Series A Preferred Shares (including, in the case of any such consolidation, merger or sale in which the successor entity or purchasing entity is other than the Company,
an immediate adjustment of the Conversion Price to the value for the Common Stock reflected by the terms of such consolidation, merger or sale, if the value so reflected is less than the Conversion Price in effect immediately prior to such
consolidation, merger or sale). The Company will not effect any such consolidation, merger or sale, unless prior to the consummation thereof, the successor entity (if other than the Company) resulting from consolidation or merger or the entity
purchasing such assets assumes, by written instrument (in form and substance reasonably satisfactory to a majority of the Holders) the obligation to deliver to each Holder such shares of stock, securities or assets as, in accordance with the
foregoing provisions, such Holder may be entitled to acquire. Person shall mean an individual, a limited liability company, a partnership, a joint venture, a corporation, a trust, an unincorporated organization and a government or
any department or agency thereof.

(iv) Notices.

(A) Immediately upon any adjustment pursuant hereto of the Adjusting Closing Bid Prices or the Fixed Conversion Price, the Company will
give written notice thereof to each Holder, setting forth in reasonable detail and certifying the calculation of such adjustment.

(B) The Company will give written notice to each Holder 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, or
(II) for determining rights to vote with respect to any Organic Change, dissolution or liquidation; provided that in no event shall such notice be provided to such Holder prior to such information being made known to the public.



---

(C) The Company will also give written notice to each Holder at least twenty
(20) days prior to (i) the date on which any Organic Change, dissolution or liquidation will take place and (ii) the anticipated closing date of any Subsequent Financing.

(v) Successive adjustments in the Adjusting Closing Bid Prices and the Fixed Conversion Price shall be made whenever any event specified
above shall occur. All calculations under this Section 2(c) shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be. No adjustment in the Conversion Price shall be made if the amount of such adjustment
would be less than $0.01, but any such amount shall be carried forward and an adjustment with respect thereto shall be made at the time of and together with any subsequent adjustment which, together with such amount and any other amount or amounts
so carried forward, shall aggregate $0.01 or more.

(d) Mechanics of Conversion. Subject to the Companys
inability to fully satisfy its obligations under a Conversion Notice (as defined below) as provided for in Section 4 below:

(i) Holders Delivery Requirements. To convert Series A Preferred Shares into full shares of Common Stock on any Conversion Date, the Holder thereof shall (A) deliver or transmit by facsimile, for receipt on or prior to
11:59 p.m., Eastern Time on such date, a copy of a fully executed notice of conversion set forth on the reverse of the Certificates of the Series A Preferred Shares (the Conversion Notice), to the Company or its designated
transfer agent (the Transfer Agent), and (B) on the same date, surrender to a common carrier for delivery to the Company or the Transfer Agent, the original certificates representing the Series A Preferred Shares 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 and any other materials
required by Section 13.

(ii) Companys Response. Upon receipt by the Company of a facsimile copy of a
Conversion Notice, the Company shall by the next business day send, via facsimile, a confirmation of receipt of such Conversion Notice to such Holder. Upon receipt by the Company or the Transfer Agent of the Preferred Stock Certificates to be
converted pursuant to a Conversion Notice, together with the originally executed Conversion Notice, the Company or the Transfer Agent (as applicable) shall, on the next business day following the date of receipt (or the second business day following
the date of receipt if received after 11:00 a.m. local time of the Company or Transfer Agent, as applicable), (I) issue and surrender to a common carrier for overnight delivery to the address as specified in the Conversion Notice, a certificate,
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, or



---

(II) if the Holder requests and if such shares shall not require any restrictive legend, credit such aggregate number of shares of Common Stock to which the
Holder shall be entitled to the Holders or its designees balance account with The Depository Trust Company or (III) if the Holder requests and if such shares shall not require any restrictive legend, issue shares in electronic format
(e.g., via DWAC).

(iii) Dispute Resolution. In the case of a dispute as to the determination of the Conversion
Price, the Company shall promptly issue to the Holder the number of shares of Common Stock that is not disputed and shall submit the disputed determinations or arithmetic calculations to the Holder via facsimile within one (1) business day of
receipt of such Holders Conversion Notice. If such Holder and the Company are unable to agree upon the determination of the Conversion Price within one (1) business day of such disputed determination or arithmetic calculation being
submitted to the Holder, then the Company shall within one (1) business day submit via facsimile the disputed determination of the Conversion Price to an independent, reputable accounting firm of national standing acceptable to the Company and
such Holder of Series A Preferred Shares. The Company shall cause such accounting firm to perform the determinations or calculations and notify the Company and the Holder of the results no later than forty-eight (48) hours from the time it
receives the disputed determinations or calculations. Such accounting firms determination shall be binding upon all parties absent manifest error.

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

(v) Companys Failure to Timely
Convert. If the Company shall fail (other than as a result of the situations described in Section 4(a) with respect to which the Holder has elected, and the Company has satisfied its obligations under, one of the options set forth in
subparagraphs (i) through (iv) of Section 4(a)) to issue to a Holder on a timely basis as described in this Section 2(d), a certificate for the number of shares of Common Stock to which such Holder is entitled upon such
Holders conversion of Series A Preferred Shares, the Company shall pay damages to such Holder equal to the greater of (A) actual damages incurred by such Holder as a result of such Holders needing to buy in shares of
Common Stock to satisfy its securities delivery requirements (Buy In Actual Damages) and (B) after the effective date of the Registration Statement if the Company fails to deliver such certificates within five days after the
last possible date which the Company could have issued such Common Stock to such Holder without violating this Section 2(d), on each date such conversion is not timely effected, in an amount equal to 1% of the product of (A) the number of
shares of Common Stock not issued to the Holder on a timely basis and to which such Holder is entitled and (B) the Closing Bid Price of the Common Stock on the last possible date which the Company could have issued such Common Stock to such
Holder without violating this Section 2(d).



---

(e) Mandatory Conversion. If any Series A Preferred Shares remain outstanding on
the Mandatory Conversion Date (as defined below), then all such Series A Preferred Shares shall be converted as of such date in accordance with this Section 2 as if the Holders had given the Conversion Notice on the Mandatory Conversion Date,
and the Conversion Date had been fixed as of the Mandatory Conversion Date, for all purposes of this Section 2. All Holders shall thereupon and within two (2) business days thereafter surrender all Preferred Stock Certificates, duly
endorsed for cancellation, to the Company or the Transfer Agent. No person shall after the Mandatory Conversion Date have any rights in respect of Series A Preferred Shares, except the right to receive shares of Common Stock on conversion thereof as
provided in this Section 2. Mandatory Conversion Date means August 21, 2002; provided, however, the Mandatory Conversion Date may be extended as set forth in Sections 3(d) (i) and (ii) hereof.

(f) Fractional Shares. The Company shall not issue any fraction of a share of Common Stock upon any conversion. All
shares of Common Stock (including fractions thereof) issuable upon conversion of more than one Series A Preferred Share by a Holder shall be aggregated for purposes of determining whether the conversion would result in the issuance of a fraction of
a share of Common Stock. If, after the aforementioned aggregation, 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 or down to the nearest whole
share.

(g) Taxes. The Company shall pay any and all taxes which may be imposed upon it with respect to the issuance
and delivery of Common Stock upon the conversion of the Series A Preferred Shares.

(3) Conversion/Redemption Upon Major Transaction;
Redemption Option Upon Triggering Event; Company Redemption Option.

(a) Conversion/Redemption Upon Major
Transaction. Upon (i) a public announcement by the Company of a Major Transaction (the Announcement Date) or (ii) receipt by the Holders of a Notice of Major Transaction (as defined below), then following the vote of
at least a majority of the Series A Preferred Shares, all of the Series A Preferred Shares then outstanding shall automatically be converted in accordance with Sections 2(d) and 3(e) hereof, calculated as if a Conversion Notice had been given to the
Company on the Announcement Date and effective just prior to the consummation of such transaction; provided, however, if the Company is unable to deliver Common Stock that may be forthwith sold pursuant to an effective Registration Statement to the
Holders to satisfy the request set forth in such Conversion Notice, the Company shall be obligated to (i) deliver to the Holders as many shares of Common Stock as may be forthwith sold pursuant to an effective Registration Statement and then
(ii) pay the Holders the balance of the value of such outstanding Series A Preferred Shares in cash at a price per Series A Preferred Share equal to the product of (A) the aggregate number of shares of Common Stock for which each such
Series A Preferred Share would be converted into pursuant to such Conversion Notice (the Mandatory Transaction Shares) multiplied by (B) the closing price of the Common Stock on such date (Major Transaction
Redemption Price). In the event that the Company fails to pay the Holders as provided in this Section 3(a), interest shall



---

accrue at the rate of 2% per month (or such leaser amount allowed by law) on such outstanding amounts and be due and payable in arrears on the last day
of each month (the Mandatory Interest). The Company may elect at any time to pay such outstanding cash amounts by delivering to the Holders Common Stock that immediately may be sold pursuant to an effective Registration Statement
in an amount equal to the aggregate of (i) the Mandatory Transaction Shares and (ii) the number of shares of Common Stock that the Mandatory Interest then due and payable could purchase on such date at the average of the Closing Bid Prices
for the five trading days immediately preceding. If conversion does not occur under this Section 3(a), any Holder may, by delivery of a notice of election to redeem no later than three (3) business days prior to the consummation of the
Major Transaction, require the Company to redeem, immediately prior to the consummation of the Major Transaction, such Holders Series A Preferred Shares at a price per Series A Preferred Share equal to the sum of (i) 120% of the Stated
Value, or in the event of the merger or consolidation of the Company into another Person (or a reverse triangular merger), 130% of the Stated Value, plus (ii) accrued but unpaid dividends thereon. In the event a Major Transaction is not
consummated subsequent to delivery to the Company of a notice of election to redeem with respect to such failed Major Transaction, then such notice shall be deemed null and void and such Holders shall be treated as though such failed Major
Transaction was not contemplated.

(b) Redemption Option Upon Triggering Event. In addition to all other rights of
the Holders contained herein, after a Triggering Event (as defined below), each Holder of shall have the right in accordance with Section 3(f), at such Holders option, to require the Company to redeem all or a portion of such
Holders Series A Preferred Shares at a price per Series A Preferred Share equal to the sum of (i) 130% of the Stated Value plus (ii) accrued but unpaid dividends thereon (the Triggering Event Redemption Price and,

provided that any demand for redemption under this Section 3(d)(i) must be made by a Holder within 30 days after receipt of notice from the Company of the termination of a Suspension Period Default;

(ii) failure of the Common Stock issued or issuable upon conversion of the Series A Preferred Shares to be saleable under the Registration

of such Holders Series A Preferred Shares by delivering written notice thereof via facsimile and overnight courier (Notice of Redemption at Option of Holder Upon Triggering Event) to the Company, which Notice of Redemption
at Option of Holder Upon Triggering Event shall indicate (i) the number of Series A Preferred Shares that such Holder is requesting redemption for and (ii) the applicable Redemption Price, as calculated pursuant to Section 3(b) above.

(g) Redemption At Option of the Company. At any time after the second anniversary of the Initial Issuance Date, the
Company, solely at its option, may elect to redeem the Series A Preferred Shares, in whole or in part, pro rata (by number of Series A Preferred Shares held) from all of the Holders by delivering notice to the Holders of the Companys election
to redeem not less than that number of shares of Series A Preferred Shares which would require an aggregate Company Redemption Price of at least $500,000 (Notice of Company Redemption) at a redemption price per Series A Preferred
Share equal to the sum of (i) 125% of the Stated Value plus (ii) accrued but unpaid dividends thereon (the Company Redemption Price).

(h) Payment of Redemption Price. Upon (i) the occurrence of a Major Transaction, (ii) the Companys receipt of a
Notice(s) of Redemption at Option of Holder Upon Triggering Event from any Holder or (iii) the delivery by the Company of a Notice of Company Redemption, the Company shall immediately notify each Holder by facsimile of the mechanics of the
delivery of each Holders Preferred Stock Certificates and each Holder shall thereafter promptly (or in the case of a Notice of Company Redemption, prior to the specified date) send such Holders Preferred Stock Certificates to be redeemed
to the Company. The Company shall deliver the applicable Redemption Price or Company Redemption Price, as applicable, to such Holder (i) within ten (10) days after the Companys delivery of a Notice of Major Transaction or the
Companys receipt of notices to affect a redemption or (ii) on the date specified on the Notice of Company Redemption, which date shall be no less than sixty (60) days after delivery of the Notice of Company Redemption; 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 Shares, (i) in the case of the occurrence of a Major Transaction or
receipt of a Notice of Redemption at Option of Holder Upon Triggering Event, the Company shall redeem an amount from each Holder equal to such Holders pro-rata amount (based on the number of Series A Preferred Shares to be redeemed by such
Holder relative to the number of Series A Preferred Shares to be redeemed by all Holders) of all Series A Preferred Shares being redeemed and (ii) in the case of the Company Redemption Option, the Companys redemption election shall be
null and void.



---

(i) In the case of the occurrence of a Major Transaction or the receipt of Notice(s) of
Redemption at Option of Holder Upon Triggering Event, if the Company shall fail to redeem all of the Series A Preferred Shares 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 may have under this Certificate of Determination and the Securities Purchase Agreement between the Company and the initial Holders (the Securities Purchase Agreement), the Redemption Price
payable in respect of such unredeemed Series A Preferred Shares shall bear interest at the rate of 1.25% per month (prorated for partial months) until paid in full. In the case of a Triggering Event or delivery of a Notice of Company
Redemption, until the Company pays such unpaid Redemption Price or Company Redemption Price, as applicable, in full to each Holder, Holders of the Series A Preferred Shares submitted for redemption pursuant to this Section 3 and for which the
applicable Redemption Price or Company Redemption Price, as applicable, has not been paid, shall have the option (the Void Optional Redemption Option) to, in lieu of redemption, require the Company to promptly return to each
Holder all of the Series A Preferred Shares that were submitted for redemption by such Holder under this Section 3 and for which the Redemption Price or Company Redemption Price, as applicable, 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 Redemption Price or Company Redemption Price,
as applicable, to each Holder, (i) the Notice(s) of Redemption at Option of Holder Upon Triggering Evens or Notice of Company Redemption shall be null and void with respect to those Series A Preferred Shares submitted for redemption and for
which the Redemption Price or Company Redemption Price, as applicable, has not been paid, and (ii) the Company shall immediately return any Series A Preferred Shares submitted to the Company by each Holder for redemption under this
Section 3(i) and for which the Redemption Price or Company Redemption Price, as applicable, has not been paid. Notwithstanding the foregoing, in the event of a dispute as to the determination of the arithmetic calculation of the Redemption
Price, or Company Redemption Price, as applicable, such dispute shall be resolved pursuant to Section 2(d)(iii) above. Payments provided for in this Section 3 shall have priority to payments to other stockholders in connection with a Major
Transaction.

(j) In the event of a Suspension Period, Effectiveness Suspension Period or Delisting Period, then the
Mandatory Conversion Date shall by extended by the aggregate number of days in all applicable periods multiplied by 1.5 (the product of which shall be rounded up to the nearest whole number). Furthermore, in the event of (i) a Suspension Period
Default, (ii) a Delisting Period Default or (iii) an Effectiveness Suspension Period for either any thirty (30) non-consecutive trading days in any period of 365 consecutive days or for any six (6) non-consecutive trading days in the
180 day period commencing from the date the Registration Statement is declared effective, then the Conversion Percentage then in effect shall be reduced by (x) 0.02 immediately following such event identified in (i), (ii) or
(iii) above and (y) an additional 0.02 for each aggregated 30 trading days of any of the events set forth in (i), (ii) and (iii) above after the occurrence of any such event.



---

(4) 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 for any reason, including, without limitation, because the Company (x) docs not have a sufficient number of shares of Common Stock authorized and
available, (y) is otherwise prohibited by applicable law, the Nasdaq Cap or by the rules or regulations of any stock exchange, interdealer quotation system or other self-regulatory organization with jurisdiction over the Company or its
securities from issuing all or any portion of the Common Stock which is to be issued to a Holder pursuant to a Conversion Notice or (z) 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 2(d) above and, with respect to the unconverted Series A Preferred
Shares, the Holder, solely at such Holders option, can elect to (unless the Company issues and delivers the Conversion Shares underlying the unconverted Series A Preferred Shares prior to the Holders election hereunder, in which case
such Holder shall only be entitled to receive Buy In Actual Damages under Section 2(d)(v)):

(i) require the Company to
redeem from such Holder those Series A Preferred Shares for which the Company is unable to issue Common Stock in accordance with such Holders Conversion Notice (Required Redemption) at a price per Series A Preferred Share
(the Required Redemption Price) equal to the aggregate of (i) 130% of the Stated Value plus (ii) accrued but unpaid dividends thereon;

(ii) if the Companys inability to fully convert Series A Preferred Shares is pursuant to Section 4(a)(z) above, require the Company
to issue restricted shares of Common Stock in accordance with such Holders Conversion Notice and pursuant to Section 2(d) above;

(iii) void its Conversion Notice and retain or have retained, as the case may be, the reconverted Series A Preferred Shares that were to be converted pursuant to such Holders Conversion Notice; or

(iv) if the Companys inability to fully convert Series A Preferred Shares is pursuant to such rules and regulations described in
Section 4(a)(y) above, require the Company to issue shares of Common Stock in accordance with such Holders Conversion Notice and pursuant to Section 2(d) above at a Conversion Price equal to the average of the Closing Bid Prices of
the Common Stock for the five (5) consecutive trading days preceding such Holders Notice in Response to Inability to Convert (as defined below) (but only if doing so would not contravene such rules and regulations).

(b) Mechanics of Fulfilling Holders Election. The Company shall forthwith send via facsimile to a Holder, upon receipt of a
facsimile copy of a Conversion Notice from such Holder which cannot be fully satisfied as described in Section 4(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 Shares which cannot be converted and (iii) the applicable Required Redemption Price. Such Holder must within five (5) business days of receipt of such Inability to Fully Convert Notice deliver written
notice via facsimile to the Company (Notice in Response to Inability to Convert) of its election pursuant to Section 4(a) above. Failure to deliver a Notice in Response to Inability to Convert shall be deemed an election
pursuant to Section 4(a)(i).

(c) Payment of Required Redemption Price. If such Holder shall elect to have its
shares redeemed pursuant to Section 4(a)(i) above, the Company shall pay the Required Redemption Price in cash to such Holder within ten (10) days of the Companys receipt of the Holders Notice in Response to Inability to
Convert (the Required Redemption Payment Period). If the Company shall fail to pay the applicable Required Redemption Price to such holder on a timely basis as described in this Section 4(c) (other than pursuant to a dispute
as to the determination of the arithmetic calculation of the Required Redemption Price), in addition to any remedy such Holder may have under this Certificate of Determination and the Securities Purchase Agreement, such unpaid amount shall bear
interest at the rate of 1.25% per month (prorated for partial months) until paid in full. From and after the expiration of the Required Redemption Payment Period until the full Required Redemption Price is paid in full to such Holder, such
Holder may void the Required Redemption with respect to those Series A Preferred Shares for which the full Required Redemption Price has not been paid and receive back such Series A Preferred Shares. Notwithstanding the foregoing, if the Company
fails to pay the applicable Required Redemption Price within such ten (10) day time period due to a dispute as to the determination of the arithmetic calculation of the Required Redemption Price, such dispute shall be resolved pursuant to
Section 2(d)(iii) above.

(d) Pro-rata Conversion and Redemption. In the event the Company receives a Conversion Notice from
more than one Holder on the same day and the Company can convert and redeem some, but not all, of the Series A Preferred Shares pursuant to this Section 4, the Company shall convert and redeem from each Holder electing to have Series A
Preferred Shares converted and redeemed at such time an amount equal to such Holders pro-rata amount (based on the number of Series A Preferred Shares held by such Holder relative to the number of Series A Preferred Shares outstanding) of all
Series A Preferred Shares being converted and redeemed at such time.

(5) Reissuance of Certificates. In the event of a conversion
or redemption pursuant to this Certificate of Determination of less than all of the Series A Preferred Shares represented by a particular Preferred Stock Certificate, the Company shall promptly cause to be issued and delivered to the Holder of such
Series A Preferred Shares a Preferred Stock Certificate representing the remaining Series A Preferred Shares which have not been so converted or redeemed.

(6) Reservation of Shares. The Company shall, so long as any of the Series A Preferred Shares 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 Shares, such number of shares of Common Stock as shall from time to time be sufficient to effect the conversion of all of the Series A Preferred Shares then outstanding.



---

(7) Dividends. The Holders shall be entitled to receive cumulative dividends at the rate of 3% of
the Stated Value per annum per Series A Preferred Share (the Dividend). Such Dividend shall be payable quarterly in arrears on the last day of March, June, September and December of each year, commencing on September 30, 1998
(each of such dates being a Dividend Payment Date). Such Dividend shall accrue on each Series A Preferred Share from the Initial Issuance Date (with appropriate proration for any partial dividend period) and shall accrue from
day-to-day, whether or not earned or declared. Dividend payments made with respect to Series A Preferred Shares may be made, subject to the terms hereof, in cash or, at the option of and in the sole discretion of the Board of Directors of the
Company, in whole or in part, by issuing fully paid and non-assessable Common Stock (valued at the average Closing Bid Price for the ten (10) trading days immediately preceding the Dividend Payment Date) plus the amount of cash dividend paid in
part, if any, is equal to the amount of the cash dividend which would otherwise be paid on such Dividend Payment Date if such Dividend were paid entirely in cash. The issuance of such Common Stock (plus the amount of cash dividend, if any, paid
together therewith) shall constitute full payment of such Dividend. In no event shall an election by the Board of Directors of the Company to pay Dividends, in whole or in part, in cash on any Dividend Payment Dates preclude the Board of Directors
of the Company from electing any other available alternative in respect of all or any portion of any subsequent Dividend. On the Initial Issuance Date, the Company shall provide written notice to the Holders specifying whether Dividends shall be
paid in the future in cash, Common Stock or a specified combination thereof. This notice shall remain in effect unless the Company delivers a notice changing the individual payment method at least twenty (20) days prior to a Dividend Payment Date.

(8) Liquidation, Dissolution, Winding-Up. In the event of any voluntary or involuntary liquidation, dissolution or winding up of
the Company, 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 stockholders (the Preferred Funds), before any amount shall be
paid to the holders of any of the capital stock of the Company of any class junior in rank to the Series A Preferred Shares in respect of the preferences as to the distributions and payments on the liquidation, dissolution and winding up of the
Company, an amount per Series A Preferred Share equal to the sum of (i) Stated Value and (ii) all accrued and unpaid dividends (such sum being referred to as the Liquidation Value); provided that, if the Preferred Funds are
insufficient to pay the full amount due to the Holders and holders of shares of other classes or series of preferred stock of the Company that are of equal rank with the Series A Preferred Shares as to payments of Preferred Funds (the Pari
Passu Shares), then each Holder and each holder of Pari Passu Shares shall receive a percentage of the Preferred Funds equal to the full amount of Preferred Funds payable to such holder as a liquidation preference, in accordance with their
respective Certificate of Determination, as a percentage of the full amount of Preferred Funds payable to all Holders and holders of Pari Passu Shares. The purchase or redemption by the Company of stock of any class, in any manner permitted by law,
shall not, for the purposes hereof, be regarded as a liquidation, dissolution or winding up of the Company. Neither the consolidation or merger of the Company with or into any other Person, nor the sale or transfer by the Company of less than
substantially all of its assets, shall, for the purposes hereof, be deemed to be a liquidation, dissolution or winding up of the Company.



---

(9) Preferred Rank. Prior to the one year anniversary of the Initial Issuance Date, all shares of
Common Stock of the Company and all other series of capital stock authorized or issued by the Company (other than pari passu shares of preferred stock approved by a majority of the then outstanding Series A Preferred Shares) shall be of junior rank
to all Series A Preferred Shares in respect to the preferences as to distributions and payments upon the liquidation, dissolution and winding up of the Company. Following the one year anniversary of the Initial Issuance Date, as long as the Series A
Preferred Shares initially issued remain outstanding, then without the prior express written consent of the Holders of not less than a majority of the then outstanding Series A Preferred Shares, the Company shall not hereafter authorize or issue
additional or other capital stock that is of senior rank to the Series A Preferred Shares in respect of the preferences as to distributions and payments upon the liquidation, dissolution and winding up of the Company. Without the prior express
written consent of the Holders of not less than a majority of the then outstanding Series A Preferred Shares, the Company shall not hereafter authorize or make any amendment to the Companys Articles of Incorporation or bylaws, or file any
resolution of the Board of Directors of the Company with the California Secretary of State containing any provisions, which would adversely affect or otherwise impair the rights or relative priority of the Holders relative to the holders of the
Common Stock or the holders of any other class of capital stock. In the event of the merger or consolidation of the Company whereby the Company is the surviving corporation in such merger or consolidation (other than a reverse triangular merger),
the Series A Preferred Shares shall maintain their relative powers, designations and preferences provided for herein and no such merger shall result inconsistent therewith.

(10) Restriction on Redemption and Cash Dividends With Respect to Other Capital Stock. Until all of the outstanding Series A Preferred Shares have
been converted or redeemed as provided herein, the Company shall not, directly or indirectly, redeem or declare or pay any cash dividend or distribution on its Common Stock or any other series of preferred stock of the Company without the prior
express written consent of the Holders of not less than a majority of the then outstanding Series A Preferred Shares.

(11) Limitation
on Number of Conversion Shares. The Company shall not be obligated to issue, in the aggregate, more than that number of shares of Common Stock (such amount to be proportionately and equitably adjusted from time to time in the event of stock
splits, stock dividends, combinations, reverse stock splits, reclassification, capital reorganizations and similar events relating to the Common Stock) (the Nasdaq Cap) that upon conversion of the Series A Preferred Shares, would
constitute a breach of the Companys obligations under the rules or regulations of Nasdaq or any other principal securities exchange or trading market upon which the Common Stock becomes traded; provided, however, that if the
Company cannot issue shares of Common Stock upon receipt of a Conversion Notice due to the Nasdaq Cap, the Company shall use its best efforts to obtain shareholder approval to exceed the Nasdaq Cap, and to the extent such approval is not received,
then the Holders shall be entitled to those rights and remedies contained herein, including those rights and remedies identified in Section 4. The Nasdaq Cap shall be allocated among the Series A Preferred Shares pro rata based on the total
number of authorized Series A Preferred Shares.



---

(12) Vote to Change the Terms of Series A Preferred Shares. 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 a majority of the then outstanding Series A Preferred Shares, shall be required for any change to this Certificate of Determination 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 Shares.

(13) 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 Series A Preferred Shares, and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder 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, the Company shall not be obligated to re-issue Preferred Stock Certificates
if the Holder contemporaneously requests the Company to convert such Series A Preferred Shares into Common Stock.

C. The authorized number
of shares of Preferred Stock of said corporation is 18,000,000, none of which has been issued. The authorized number of shares of Series A Convertible Preferred Stock of said corporation is 3,000, none of which has been issued.

We further declare under penalty of perjury under the laws of the State of California that the matters set forth in this Certificate are true and correct
of our own knowledge.
