On or after the date fixed for redemption by the Holders, each Holder of Series B Notes shall surrender his, her or its certificates evidencing all Series B Notes to be redeemed to the Company at its principal executive offices and shall thereupon be entitled to receive payment of the redemption price for the Series B Notes redeemed within 90-days of delivery of the redemption notice provided pursuant to this Section 2(a).

Section 4.    Conversion.

(a)    Conversion Right. Subject to the terms hereof, the Holder shall have the right, at such Holder’s option, at any time and from time to time, to convert the outstanding Principal Amount under this Series B Note in whole or in part by delivering to the Company a fully executed notice of conversion in the form of conversion notice attached hereto as Exhibit A (the “Conversion Notice”), which may be delivered in the manner for providing notices to the Company provided for in the Purchase Agreement.

(b)    Common Stock Issuance upon Conversion.

(i)    Conversion Date Procedures. Upon conversion of this Series B Note pursuant to Section 4(a), the outstanding Principal Amount hereunder shall be converted into such number of shares of Common Stock as is determined by dividing (x) the Principal Amount elected to be converted, by (y) the then-applicable Conversion Price. The date of any Conversion Notice is referred to herein as the “Conversion Date”. If the Holder is converting less than all of the outstanding Principal Amount hereunder pursuant to a Conversion Notice and has delivered this Series B Note to the Company, the Company shall promptly deliver to the Holder (but no later than five Trading Days after the Conversion Date) a Series B Note for such outstanding Principal Amount as has not been converted if this Series B Note has been tendered to the Company for partial conversion. The Holder shall not be required to physically surrender this Series B Note to the Company upon any conversion or hereunder unless the full outstanding Principal Amount represented by this Series B Note is being converted or repaid. The Company shall maintain accurate records showing the outstanding Principal Amount so converted and repaid and the dates of such conversions or repayments.

(ii)    Stock Certificates or DWAC. The Company will deliver to the Holder not later than three Trading Days after the Conversion Date, a certificate or certificates (which shall be free of restrictive legends and trading restrictions if a Registration Statement has been declared effective covering such shares or such shares may be resold pursuant to Rule 144 under the Securities Act), representing the number of shares of Common Stock being acquired upon the conversion of this Series B Note. In lieu of delivering physical certificates representing the shares of Common Stock issuable upon conversion of this Series B Note, provided the Company’s transfer agent is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer (“FAST”) program, upon request of the Holder, the Company shall use commercially reasonable efforts to cause its transfer agent to electronically transmit such shares issuable upon conversion to the Holder (or its designee), by crediting the account of the Holder’s (or such designee’s) prime broker with DTC through its Deposit Withdrawal at Custodian system (provided that the same time periods herein as for stock certificates shall apply). If in the case of any conversion hereunder, such certificate or certificates are not delivered to or as directed by the Holder by the third Trading Day after the Conversion Date, the Holder, in addition to any other remedy the Holder may have at law or in equity, shall be entitled by written notice to the Company at any time on or before its receipt of such certificate or certificates thereafter, to rescind such conversion, in which event the Company shall immediately return this Series B Note tendered for conversion.

Any adjustment made pursuant to this Section 3(c)(i) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination.

(iii)    Rounding of Adjustments. All calculations under this Section 4 or Section 1 shall be made to the nearest 4 decimal places or the nearest 1/100th of a share, as the case may be.

(iv)    Notice of Adjustments. Whenever the Conversion Price is adjusted pursuant hereto, the Company shall promptly deliver to each holder of the Series B Notes, a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment, provided that any failure to so provide such notice shall not affect the automatic adjustment hereunder.

(v)    Change in Control Transactions.

The terms of any such Change in Control Transaction shall include such terms so as to continue to give to the Holders the right to receive the amount of securities, cash or property upon any conversion or redemption following such Change in Control Transaction to which a holder of the Underlying Shares would have been entitled in such Change in Control Transaction.

(vi)    Notice of Certain Events. If:

A.    the Company shall declare a dividend (or any other distribution) on its Common Stock;

B.    the Company shall declare a special nonrecurring cash dividend on or a redemption of its Common Stock;

C.    the Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights;

E.    the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company;

then the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of this Series B Note, and shall cause to be mailed to the Holder at its last address as it shall appear upon the books of the Company, on or prior to the date notice to the Company’s stockholders generally is given, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange.

(vii)    Purchase Rights. 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 the Common Stock (“Purchase Rights”), then the Holder will be entitled to acquire, upon conversion of this Series B Note in accordance with its terms, a portion of the aggregate Purchase Rights which the Holder would have acquired if the Holder had held all Underlying Shares immediately before the date on which a record is taken to determine holders of the Common Stock for the grant, issue or sale of such Purchase Rights. Such portion will be determined based on the Principal Amount converted on the applicable Conversion Date in accordance the terms hereof relative to aggregate Principal Amount on the Conversion Date.

(d)    Reservation and Issuance of Underlying Securities. The Company will at all times reserve and keep available out of its authorized and unissued Common Stock solely for the purpose of issuance upon conversion of this Series B Note, free from preemptive rights or any other actual contingent purchase rights of persons other than the holders of the Series B Notes, not less than such number of shares of Common Stock as shall (subject to any additional requirements of the Company as to reservation of such shares set forth in the Purchase Agreement) be issuable upon the conversion of this Series B Note hereunder in Common Stock. The Company covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid, and nonassessable.

(e)    No Fractions. Upon a conversion hereunder the Company shall not be required to issue fractions of shares of Common Stock, but may if otherwise permitted, make a cash payment in respect of any final fraction of a share based on the closing price of a share of Common Stock on the applicable Conversion Date; provided that, if at any time the Common Stock is not traded on a securities exchange or an automated quotation system or in the over-the-counter market, the cash payment provided for by this Section 4(e) will be based on the fair market value of a share of Common Stock as determined in good faith by the Company’s board of directors and the fractional share not required to be issued pursuant to the foregoing. If the Company elects not, or is unable, to make such a cash payment, the Holder shall be entitled to receive, in lieu of the final fraction of a share, one whole share of Common Stock.

(f)    Charges, Taxes and Expenses. Issuance of certificates for shares of Common Stock upon the conversion of this Series B Note (including repayment in stock) shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the Company, and such certificates shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the event certificates for shares of Common Stock are to be issued in a name other than the name of the Holder, this Series B Note when surrendered for conversion shall be accompanied by an assignment form; and provided further, that the Company shall not be required to pay any tax or taxes which may be payable in respect of any such transfer.

(g)    Cancellation. After all of the Principal Amount has been paid in full or converted into Common Stock, this Series B Note shall automatically be deemed canceled and the Holder shall promptly surrender the Series B Note to the Company at the Company’s principal executive offices.

(h)    Notices Procedures. Any and all notices or other communications or deliveries to be provided by the Holder to the Company hereunder, including, without limitation, any Conversion Notice, shall be in writing and delivered in the manner provided for in the Purchase Agreement. Any and all notices or other communications or deliveries to be provided by the Company hereunder shall be in writing and delivered personally, by facsimile, or by a nationally recognized overnight courier service addressed to the Holder at the facsimile telephone number or address of the Holder appearing on the books of the Company, or if no such facsimile telephone number or address appears, at the principal place of business of the Holder. Any notice or other communication or deliveries hereunder shall be deemed delivered at the times provided for in the Purchase Agreement.

Section 5.    Defaults and Remedies.

(a)    Events of Default. An “Event of Default” is: (i) a default in payment of any amount due hereunder which default continues for more than five Business Days after the due date thereof; (ii) the occurrence of an “Event of Default” under the September 2013 Notes; (iii) a default in the timely issuance of Underlying Shares upon and in accordance with terms hereof, which default continues for five Business Days after the Company has received written notice informing the Company that it has failed to issue shares or deliver stock certificates within the fifth day following the Conversion Date; (iv) failure by the Company for five Business Days after written notice has been received by the Company to comply with any material provision of any of the Transaction Documents; (v) a material breach by the Company of its representations or warranties in the Transaction Documents; (vi) if at any time the Company is not subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act; (vii) if at any time the Common Stock shall not be listed or quoted for trading on the Nasdaq Stock Market, the New York Stock Exchange or the NYSE MKT; (viii) any default after any cure period under, or acceleration prior to maturity of, any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by the Company in excess of $50,000 or for money borrowed the repayment of which is guaranteed by the Company for in excess of $50,000, whether such indebtedness or guarantee now exists or shall be created hereafter (and which indebtedness or guarantee, for the avoidance of doubt, does not include the Company’s trade payables); or (ix) if the Company is subject to any Bankruptcy Event.

(b)    Remedies. If an Event of Default occurs and is continuing with respect to any of the Series B Notes, the Holder may (a) declare all of the then outstanding Principal Amount of this Series B Note to be due and payable immediately, except that in the case of an Event of Default arising from events described in clause (viii) of Section 5(a), this Series B Note shall become due and payable without further action or notice and (b) exercise any and all rights and remedies available to it under applicable law or the Transaction Documents. The remedies under this Series B Note, the Transaction Documents and applicable law shall be cumulative.

(b)    Savings Clause. In case any provision of this Series B Note is held by a court of competent jurisdiction to be excessive in scope or otherwise invalid or unenforceable, such provision shall be adjusted rather than voided, if possible, so that it is enforceable to the maximum extent possible, and the validity and enforceability of the remaining provisions of this Series B Note will not in any way be affected or impaired thereby. In no event shall the amount of interest paid hereunder exceed the maximum rate of interest on the unpaid principal balance hereof allowable by applicable law. If any sum is collected in excess of the applicable maximum rate, the excess collected shall be applied to reduce the principal debt. If the interest actually collected hereunder is still in excess of the applicable maximum rate, the interest rate shall be reduced so as not to exceed the maximum allowable under law.

(c)    Amendment. Neither this Series B Note nor any term hereof may be amended, waived, discharged or terminated other than by a written instrument signed by the Company and the Holder.

(d)    Assignment, Etc. The Holder may assign or transfer this Series B Note to any transferee only with the prior written consent of the Company, which may not be unreasonably withheld or delayed, provided that (i) the Holder may assign or transfer this Series B Note to any of such Holder’s affiliates without the consent of the Company and (ii) upon any Event of Default, the Holder may assign or transfer this Series B Note without the consent of the Company. The Holder shall notify the Company of any such assignment or transfer promptly. This Series B Note shall be binding upon the Company and its successors and shall inure to the benefit of the Holder and its successors and permitted assigns.

(e)    No Waiver. No failure on the part of the Holder to exercise, and no delay in exercising any right, remedy or power hereunder, shall operate as a waiver thereof, nor shall any single or partial exercise by the Holder of any right, remedy or power hereunder preclude any other or future exercise of any other right, remedy or power. Each and every right, remedy or power hereby granted to the Holder or allowed it by law or other agreement shall be cumulative and not exclusive of any other, and may be exercised by the Holder from time to time.

(f)    Governing Law. THIS SERIES B NOTE WILL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO ANY CONFLICTS OF LAWS PROVISIONS THEREOF THAT WOULD OTHERWISE REQUIRE THE APPLICATION OF THE LAW OF ANY OTHER JURISDICTION.

(g)    Replacement Series B Notes. This Series B Note may be exchanged by Holder at any time and from time to time for a Series B Note or Series B Notes with different denominations representing an equal aggregate outstanding Principal Amount, as reasonably requested by Holder, upon surrendering the same. No service charge will be made for such registration or exchange. In the event that Holder notifies the Company that this Series B Note has been lost, stolen or destroyed, a replacement Series B Note identical in all respects to the original Series B Note (except for registration number and Principal Amount, if different than that shown on the original Series B Note), shall be issued to the Holder, provided that the Holder executes and delivers to the Company an agreement reasonably satisfactory to the Company to indemnify the Company from any loss incurred by it in connection with the Series B Note.

(h)    Waivers of Demand, etc. The Company hereby waives demand, presentment, notice of dishonor or nonpayment, protest and notice of protest and acceptance of partial payments, whether before, at, or after the Maturity Date, all which may be made without notice to the Company and without affecting its liability to the Holder.
