4.  Covenants of Issuer during Unwind Period.  Issuer agrees with Dealer that during the Unwind Period:

For an Unwind Date Price falling between the amounts appearing in such column, the Amendment Payment Amount per Warrant will be calculated by Dealer using linear interpolation.  If the Amendment Payment Amount per Warrant is otherwise not determinable pursuant to the foregoing because the Unwind Date Price is less than the lowest Unwind Date Price set forth above, the Amendment Payment Amount per Warrant will be determined by Dealer by linear extrapolation based on the two lowest Unwind Date Prices set forth above.

ANNEX B
SHARE SETTLEMENT PROVISIONS
1.    Payment of any Daily Amendment Payment in Shares by Issuer shall be made by delivery on the Payment Date of a number of Shares satisfying the conditions set forth in paragraph 2 below (the “Registered Settlement Shares”), or a number of Shares not satisfying such conditions (the “Unregistered Settlement Shares”), in either case with a value equal to such Daily Amendment Payment, with such Shares’ value determined by Dealer in good faith and in a commercially reasonable manner (which value shall, in the case of Unregistered Settlement Shares, take into account a commercially reasonable illiquidity discount).


2.    Issuer may only deliver Registered Settlement Shares pursuant to paragraph 1 above if:
(a)    a registration statement covering the public resale of the Registered Settlement Shares by Dealer (the “Registration Statement”) shall have been filed with the Securities and Exchange Commission under the Securities Act and been declared or otherwise become effective on or prior to the date of delivery, and no stop order shall be in effect with respect to the Registration Statement; a printed prospectus relating to the Registered Settlement Shares (including any prospectus supplement thereto, the “Prospectus”) shall have been delivered to Dealer, in such quantities as Dealer shall reasonably have requested, on or prior to the date of delivery; 
(b)    the form and content of the Registration Statement and the Prospectus (including, without limitation, any sections describing the plan of distribution) shall be reasonably satisfactory to Dealer;
(c)    as of or prior to the date of delivery, Dealer and its agents shall have been afforded a reasonable opportunity to conduct a due diligence investigation with respect to Issuer customary in scope for underwritten offerings of equity securities and the results of such investigation are satisfactory to Dealer, in its good faith discretion; and
(d)    as of the date of delivery, an agreement (the “Underwriting Agreement”) shall have been entered into with Dealer in connection with the public resale of the Registered Settlement Shares by Dealer substantially similar to underwriting agreements customary for underwritten offerings of equity securities of a similar size by companies similar to Issuer, in form and substance reasonably satisfactory to Dealer, which Underwriting Agreement shall include, without limitation, provisions substantially similar to those contained in such underwriting agreements for offerings of a similar size by companies similar to Issuer relating, without limitation, to the indemnification of, and contribution in connection with the liability of, Dealer and its affiliates and the provision of customary opinions, accountants’ comfort letters and lawyers’ negative assurance letters.
3.    If Issuer delivers Unregistered Settlement Shares pursuant to paragraph 1 above:
(a)    all Unregistered Settlement Shares shall be delivered to Dealer (or any affiliate of Dealer designated by Dealer) pursuant to the exemption from the registration requirements of the Securities Act provided by Section 4(a)(2) thereof;
(b)    as of or prior to the date of delivery, Dealer and any potential purchaser of any such Unregistered Settlement Shares from Dealer (or any affiliate of Dealer designated by Dealer) identified by Dealer shall be afforded a commercially reasonable opportunity to conduct a due diligence investigation with respect to Issuer customary in scope for private placements of equity securities of a similar size by companies similar to Issuer (including, without limitation, the right to have made available to them for inspection all financial and other records, pertinent corporate documents and other information reasonably requested by them); 


10









(c)    as of the date of delivery, Issuer shall enter into an agreement (a “Private Placement Agreement”) with Dealer (or any affiliate of Dealer designated by Dealer) in connection with the private placement of such Unregistered Settlement Shares by Issuer to Dealer (or any such affiliate) and the private resale of such Unregistered Settlement Shares by Dealer (or any such affiliate), substantially similar to private placement purchase agreements customary for private placements of equity securities of a similar size by companies similar to Issuer, in form and substance commercially reasonably satisfactory to Dealer, which Private Placement Agreement shall include, without limitation, provisions substantially similar to those contained in such private placement purchase agreements for offerings of similar size by companies similar to Issuer relating, without limitation, to the indemnification of, and contribution in connection with the liability of, Dealer and its affiliates and the provision of customary opinions, accountants’ comfort letters and lawyers’ negative assurance letters, and shall provide for the payment by Issuer of all commercially reasonable fees and expenses in connection with such resale, including all commercially reasonable fees and expenses of counsel for Dealer, and shall contain representations, warranties, covenants and agreements of Issuer reasonably necessary or advisable to establish and maintain the availability of an exemption from the registration requirements of the Securities Act for such resale; and
(d)    in connection with the private placement of such shares by Issuer to Dealer (or any such affiliate) and the private resale of such shares by Dealer (or any such affiliate), Issuer shall, if so requested by Dealer, prepare, in cooperation with Dealer, a private placement memorandum in form and substance reasonably satisfactory to Dealer and customary for private placements of equity securities of similar size by companies similar to Issuer.   
4.    Dealer, itself or through an affiliate (the “Selling Agent”) or any underwriter(s), will sell, in a commercially reasonable manner and over a commercially reasonable period, all, or such lesser portion as may be required hereunder, of the Registered Settlement Shares or Unregistered Settlement Shares and any Makewhole Shares (as defined below) (together, the “Settlement Shares”) delivered by Issuer to Dealer pursuant to paragraph 5 below in a commercially reasonable manner commencing on the date one Settlement Cycle following the Termination Date (such date, the “Net Share Settlement Date” for purposes of Net Share Settlement by Issuer) and continuing until the date on which the aggregate Net Proceeds (as such term is defined below) of such sales, as determined by Dealer in a commercially reasonable manner, is equal to the Amendment Payment (such date, the “Final Resale Date”).  If the proceeds of any sale(s) made by Dealer, the Selling Agent or any underwriter(s), net of any commercially reasonable fees and commissions (including, without limitation, commercially reasonable underwriting or placement fees) customary for similar transactions of a similar size under the circumstances at the time of the offering, together with commercially reasonable carrying charges and expenses incurred in connection with the offer and sale of the Shares (including, but without limitation to, the covering of any over-allotment or short position (syndicate or otherwise)) (the “Net Proceeds”) exceed the Amendment Payment, Dealer will refund, in USD, such excess to Issuer on the date that is three (3) Currency Business Days following the Final Resale Date, and, if any portion of the Settlement Shares remains unsold, Dealer shall return to Issuer on that date such unsold Shares.  
5.    If the Calculation Agent determines that the Net Proceeds received from the sale of the Registered Settlement Shares or Unregistered Settlement Shares or any Makewhole Shares, if any, pursuant to this paragraph 5 are less than the Amendment Payment (the amount in USD by which the Net Proceeds are less than the Amendment Payment being the “Shortfall” and the date on which such determination is made, the “Deficiency Determination Date”), Issuer shall on the Exchange Business Day next succeeding the Deficiency Determination Date (the “Makewhole Notice Date”) deliver to Dealer, through the Selling Agent, a notice of Issuer’s election that Issuer shall either (i) pay an amount in cash equal to the Shortfall on the day that is one (1) Currency Business Day after the Makewhole Notice Date, or (ii) deliver additional Shares.  If Issuer elects to deliver to Dealer additional Shares, then Issuer shall deliver additional Shares in compliance with the terms and conditions of paragraph 2 or paragraph 3 above, as the case may be (the “Makewhole Shares”), on the first Clearance System Business Day which is also an Exchange Business Day following the Makewhole Notice Date in such number as the Calculation Agent commercially reasonably believes would have a market value on that Exchange Business Day equal to the Shortfall.  Such Makewhole Shares shall be sold by Dealer in accordance with the provisions above; provided that if the sum of the Net Proceeds from the sale of the originally delivered Shares and the Net Proceeds from the sale of any Makewhole Shares is less than the Amendment Payment then Issuer shall, at its election, either make such cash payment or deliver to Dealer further Makewhole Shares until such Shortfall has been reduced to zero. 


11









6.    Notwithstanding the foregoing, and without limiting the Issuer’s ability to elect to settle any Daily Amendment Payment in Shares, as provided in this Annex B, in no event shall the aggregate number of Settlement Shares and Makewhole Shares required to be delivered by the Issuer upon settlement of all Daily Amendment Payments so settled in Shares, in the aggregate, be greater than 250,000 Shares (the “Maximum Number of Shares”). For the avoidance of doubt, in no event will the Company be required to deliver cash in the event the aggregate number of Settlement Shares and Makewhole Shares required to be delivered by the Issuer upon settlement of all Daily Amendment Payments so settled in Shares, in the aggregate, would, but for the foregoing sentence, exceed the Maximum Number of Shares.
