Section&nbsp;1(d) are applicable, by notifying the Company that this Warrant is being exercised pursuant to a Cashless Exercise (as defined in Section&nbsp;1(d)). The Holder shall not be required to deliver the original Warrant in order to effect an

other type of guarantee or notarization) with respect to any Exercise Notice be required. Execution and delivery of the Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation of the original
Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares and the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant
Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three (3)&nbsp;Trading Days of the date on which the final Notice of Exercise is
delivered to the Company. Upon delivery of the Exercise Notice to the Company, the Company shall issue and dispatch by overnight courier to the address as specified in the Exercise Notice, a certificate, registered in the name of the Holder or its
designee, for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise. Upon delivery of the Exercise Notice, the Holder shall be deemed for all corporate purposes to have become the holder of record and beneficial
owner of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date of delivery of the certificates evidencing such Warrant Shares. If this Warrant is physically delivered to the Company in connection with any
exercise pursuant to this Section&nbsp;1(a) and the number of Warrant Shares represented by this Warrant submitted for exercise is greater than the number of Warrant Shares being acquired upon an exercise, then the Company shall as soon as
practicable and in no event later than three (3)&nbsp;Trading Days after any exercise and at its own expense, issue and deliver to the Holder (or its designee) a new Warrant (in accordance with Section&nbsp;6(d)) representing the right to purchase
the number of Warrant Shares issuable immediately prior to such exercise under this Warrant, less the number of Warrant Shares with respect to which this Warrant is exercised. The Company shall pay any and all transfer, stamp, issuance and similar
taxes, costs and expenses which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant. The Company&#146;s obligations to issue and deliver Warrant Shares in accordance with the terms and subject to
the conditions hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action
to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination; <U>provided</U>, <U>however</U>, that the Company shall not be required to deliver Warrant Shares with respect to an exercise prior to the Holder&#146;s

action reasonably necessary to increase the Company&#146;s authorized shares of Series C Preferred Stock and Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount for this Warrant then outstanding. Without
limiting the generality of the foregoing sentence, if the Authorized Share Failure is the result of a failure to have a sufficient number of authorized and unreserved shares of Common Stock to satisfy the Company&#146;s obligation to reserve for
issuance the Required Reserve Amount, then as soon as practicable after the date of the occurrence of such Authorized Share Failure, but in no event later than ninety (90)&nbsp;days after the occurrence of such Authorized Share Failure, the Company
shall hold a meeting of its stockholders for the approval of an increase in the number of authorized shares of Common Stock. In connection with such meeting, the Company shall provide each stockholder with a proxy statement and shall use its
reasonable best efforts to solicit its stockholders&#146; approval of such increase in authorized shares of Common Stock and to cause its board of directors to recommend to the stockholders that they approve such proposal. Notwithstanding the
foregoing, if any such time of an Authorized Share Failure, the Company is able to obtain the written consent of a majority of the shares of its issued and outstanding shares of Common Stock to approve the increase in the number of authorized shares
of Common Stock, the Company may satisfy this obligation by obtaining such consent and submitting for filing with the SEC an Information Statement on Schedule 14C. </P>

price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction). Upon the consummation of each Fundamental Transaction, the Successor Entity shall succeed to, and be

consummation of each 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 &#147;<B>Corporate Event</B>&#148;), the
Company shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon an exercise of this Warrant at any time after the consummation of the applicable Fundamental Transaction but prior to the Expiration

in a form and substance reasonably satisfactory to the Holder. The provisions of this Section&nbsp;3 shall apply similarly and equally to successive Fundamental Transactions and Corporate Events. Notwithstanding the foregoing, in the event of a
Change of Control, at the request of the Holder delivered before the 30th day after such Change of Control, the Company (or the Successor Entity) shall purchase this Warrant from the Holder by paying to the Holder, within five (5)&nbsp;Business Days
after such request (or, if later, on the effective date of the Change of Control), an amount equal to the Black Scholes Value of the remaining unexercised portion of this Warrant on the effective date of such Change of Control, payable in cash;

the Corporation shall not effect any conversion of the Series C Preferred Stock and a Holder shall not have the right to convert any portion of the Series C Preferred Stock, to the extent that, immediately prior to or after giving effect to an
attempted conversion set forth on an applicable Notice of Conversion, such Holder together with the other Attribution Parties, collectively would beneficially own a number of shares of Common Stock in excess of the Beneficial Ownership Limitation
(as defined below).&nbsp;For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by such Holder and its Attribution Parties shall include the number of shares of Common Stock held by such Holder and all other
Attribution Parties plus the number of shares of Common Stock issuable upon conversion of the Series C Preferred Stock subject to the Notice of Conversion with respect to which such determination is being made, but shall exclude the number of shares
of Common Stock which would be issuable upon (A)&nbsp;conversion of the remaining, unconverted Series C Preferred Stock beneficially owned by such Holder or any of its Attribution Parties, and (B)&nbsp;exercise or conversion of the unexercised or
unconverted portion of any other securities of the Corporation (including, without limitation, any convertible notes or convertible preferred stock or warrants) beneficially owned by such Holder or any of its Attribution Parties that are subject to
a limitation on conversion or exercise similar to the limitation contained herein.&nbsp;Except as set forth in the preceding sentence, for purposes of this Section&nbsp;6(c), beneficial ownership shall be calculated in accordance with
Section&nbsp;13(d) of the Exchange Act and the applicable regulations of the Commission. To the extent that the limitation contained in this Section&nbsp;6(c) applies, the determination of whether shares of Series C Preferred Stock may be converted
by the Holder (in relation to other securities owned by the Holder together with its Attribution Parties) and of the number of shares of Series C Preferred Stock that may be converted shall be in the sole discretion of the Holder, and the
Corporation shall have no obligation to verify or confirm the accuracy of such determination. For purposes of this Section&nbsp;6(c), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding
shares of Common Stock as reflected in (A)&nbsp;the Corporation&#146;s most recent Annual Report on Form <FONT STYLE="white-space:nowrap">10-K,</FONT> Quarterly Report on Form <FONT STYLE="white-space:nowrap">10-Q</FONT> and Current Reports on Form <FONT
STYLE="white-space:nowrap">8-K</FONT> or other public filing with the Commission, as the case may be, (B)&nbsp;a more recent public announcement by the Corporation, or (C)&nbsp;any other written notice by the Corporation or the transfer agent
setting forth the number of shares of Common Stock outstanding (the &#147;<B><U>Reported Outstanding Share Number</U></B>&#148;).&nbsp;If the Corporation receives a Notice of Conversion from a Holder at a time when the actual number of outstanding
shares of Common Stock is less than the Reported Outstanding Share Number, the Corporation shall notify the Holder in writing of the number of shares of Common Stock then outstanding and, to the extent that such Notice of Conversion would otherwise
cause the Holder&#146;s beneficial ownership, as determined pursuant to this Section&nbsp;6(c), to exceed the Beneficial Ownership Limitation, the Holder must notify the Corporation of a reduced number of shares of Series C Preferred Stock to be
converted pursuant to such Notice of Conversion. For any reason at any time, upon the written or oral request of the Holder, the Corporation shall within one (1)&nbsp;Business Day confirm orally and in writing or by electronic mail to the Holder the
number of shares of Common Stock then outstanding.&nbsp;In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to any actual conversion or exercise of securities of the Corporation, including shares of
Series C Preferred Stock, by such Holder or its Attribution Parties since the date as of which the Reported Outstanding Share Number was reported. In the event that the issuance of Common Stock to the Holder upon conversion of shares of Series C
Preferred Stock results in the Holder and the other Attribution Parties being deemed to beneficially own, in the aggregate, more than the Beneficial Ownership Limitation of the number of outstanding shares of Common Stock (as determined under
Section&nbsp;13(d) of the Exchange Act), the number of shares of Common Stock so issued by which the Holder&#146;s and the other Attribution Parties&#146; aggregate beneficial ownership exceeds the Beneficial Ownership Limitation (the
&#147;<B><U>Excess Shares</U></B>&#148;) shall be deemed null and void and shall be cancelled ab initio, and the Holder shall not have the power to vote or to transfer the Excess Shares. As soon as reasonably practicable after the issuance of the
Excess Shares has been deemed null and void, the Corporation shall return to the Holder the number of shares of Series C Preferred Stock corresponding to such excess. The &#147;<B><U>Beneficial Ownership Limitation</U></B>&#148; shall be 4.99% (or
such other percentage (not to exceed 19.99%) that the Holder has elected by written notice to the Company prior to the date of this Certificate of Designation in respect of Series C Preferred Stock or any warrant or other security convertible into
or exercisable for shares of Common Stock) of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock pursuant to such Notice of Conversion (to the extent permitted pursuant to
this Section&nbsp;6(c)). A Holder may, upon providing written notice to the Corporation, elect to increase or decrease the Beneficial Ownership Limitation (not to exceed 19.99%); provided that (i)&nbsp;any increase will not be effective until the
sixty-first (61<SUP STYLE="font-size:85%; vertical-align:top">st</SUP>) day after delivery of such notice to the Corporation, (ii)&nbsp;the Holder may elect, upon delivery of written notice to the Corporation, not to have the right to increase the
Beneficial Ownership Limitation from and after such time as may be specified in such notice, and any such election shall be irrevocable (and, if the Holder has made such irrevocable election prior to the date of this Certificate of Designation in
respect of Series C Preferred Stock or any warrant or other security convertible into or exercisable for shares of Common Stock, then the Holder shall not have the right to increase the Beneficial Ownership Limitation at any time), and
(iii)&nbsp;any such increase or decrease will apply only to the Holder and the other Attribution Parties and not to any other holder of Series C Preferred Stock that is not an Attribution Party of the Holder. For purposes of clarity, the shares of
Common Stock issuable upon conversion of the Series C Preferred Stock in excess of the Beneficial Ownership Limitation shall not be deemed to be beneficially owned by the Holder for any purpose included for purposes of Section&nbsp;13(d) or Rule <FONT
STYLE="white-space:nowrap">16a-1(a)(1)</FONT> of the Exchange Act. No prior inability to convert shares of Series C Preferred Stock pursuant to this Section&nbsp;6(c) shall have any effect on the applicability of the provisions of this
Section&nbsp;6(c) with respect to any subsequent determination of conversion. The provisions of this Section&nbsp;6(c) shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section&nbsp;6(c) to the
extent necessary to correct this Section&nbsp;6(c) or any portion of this Section&nbsp;6(c) which may be defective or inconsistent with the intended beneficial ownership limitation contained in this Section&nbsp;6(c) or to make changes or

might otherwise limit such obligation of the Corporation to such Holder in connection with the issuance of such Conversion Shares. The Corporation understands that a delay in the delivery of the Conversion Shares after the Share Delivery Date could
result in economic loss to the Holder. As compensation to the Holder for such loss, if (i)&nbsp;the Corporation fails to cause the Corporation&#146;s transfer agent to transmit to the Holder the Conversion Shares in accordance with the provisions of
Section&nbsp;6(a) above pursuant to a Notice of Conversion on or before the Share Delivery Date (other than a failure caused by incorrect or incomplete information provided by the Holder to the Corporation) and (ii)&nbsp;the Holder has not exercised

in a manner otherwise than in strict conformity with the terms of this provision to the extent necessary to correct this provision or any portion of this provision which may be defective or inconsistent with the intended treatment of such instrument
or transaction (in any such case, a &#147;<B><U>Fundamental Transaction</U></B>&#148;), then, upon any subsequent conversion of this Series C Preferred Stock the Holders shall have the right to receive, in lieu of the right to receive Conversion
Shares, for each Conversion Share that would have been issuable upon such conversion immediately prior to the occurrence of such Fundamental Transaction (without regard to any limitations on conversion), the same kind and amount of securities, cash
or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of one share of Common Stock (the &#147;<B><U>Alternate
Consideration</U></B>&#148;). For purposes of any such subsequent conversion, the determination of the Conversion Ratio shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable
in respect of one share of Common Stock in such Fundamental Transaction, and the Corporation shall adjust the Conversion Ratio in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If
holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holders shall be given the same choice as to the Alternate Consideration it receives upon any conversion of
Series C Preferred Stock following such Fundamental Transaction. To the extent necessary to effectuate the foregoing provisions, any successor to the Corporation or surviving entity in such Fundamental Transaction shall file a new Certificate of
Designation with the same terms and conditions and issue to the Holders new preferred stock consistent with the foregoing provisions and evidencing the Holders&#146; right to convert such preferred stock into Alternate Consideration. The terms of
any agreement to which the Corporation is a party and pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this Section&nbsp;7(b) and insuring
that this Series C Preferred Stock (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction. The Corporation shall cause to be delivered to each Holder, at its last address
as it shall appear upon the stock books of the Corporation, written notice of any Fundamental Transaction at least 20 calendar days prior to the date on which such Fundamental Transaction is expected to become effective or close. </P>

default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the securities, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable
provision of the Securities Act of 1933, as amended (the &#147;Securities Act&#148;), amending the list of selling holders to include the pledgee, transferee or other successors in interest as selling holders under this prospectus. The selling
holders also may transfer the securities in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In connection with the sale of our securities or interests therein, the selling holders may enter into hedging transactions with
broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The selling holders may also sell securities short and deliver these securities to close
out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The selling holders may also enter into option or other transactions with broker-dealers or other financial institutions or the
creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell
pursuant to this prospectus (as supplemented to reflect such transaction). </P>

will be the purchase price of the securities less discounts or commissions, if any. Each of the selling holders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of
securities to be made directly or through agents. We will not receive any of the proceeds from the sale of any securities by the selling holders. Upon any exercise of the warrants by payment of cash, however, we will receive the exercise price of
the warrants. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The selling holders also may resell all or a portion of the securities in open market transactions in reliance upon Rule

any underwriters, broker-dealers or agents that participate in the sale of the securities or interests therein may be &#147;underwriters&#148; within the meaning of Section&nbsp;2(11) of the Securities Act. Any discounts, commissions, concessions or
profit they earn on any resale of the securities may be underwriting discounts and commissions under the Securities Act. The selling holders may indemnify any broker-dealer that participates in transactions involving the sale of the securities
against certain liabilities, including liabilities arising under the Securities Act. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">To the extent required, the securities to be sold,

registered or licensed brokers or dealers. In addition, in some states the securities may not be sold unless they have been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied
with. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We have advised the selling holders that the anti-manipulation rules of Regulation M under the Securities Exchange Act of 1934, as
amended, may apply to sales of securities in the market and to the activities of the selling holders and their affiliates. These rules may limit the timing of purchases and sales of the securities by such selling holders. Regulation M may also
restrict the ability of any person engaged in the distribution of the securities to engage in market-making activities with respect to the securities. All of the foregoing may affect the marketability of the securities and the ability of any person
or entity to engage in market-making activities with respect to the securities. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We have agreed to indemnify the selling holders against

to contribution. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We have agreed with the selling holders to use reasonable best efforts to cause the registration statement of which this
prospectus constitutes a part effective and to remain continuously effective until the earlier of (1)&nbsp;such time as all of the securities covered by this prospectus have been disposed of pursuant to and in accordance with such registration
statement or (2)&nbsp;the date on which all of the securities may be sold without restriction pursuant to Rule 144 of the Securities Act. </P>
