This Confirmation amends, restated and supersedes in its entirety the Confirmation in respect of the Transaction dated as of June 25, 2007. This Confirmation constitutes a “Confirmation” as referred to in the Agreement specified below.

     The definitions and provisions contained in the 2000 ISDA Definitions (the “Swap Definitions”) and the 2002 ISDA Equity Derivatives Definitions (the “Equity Definitions” and, together with the Swap Definitions, the “Definitions”), in each case as published by the International Swaps and Derivatives Association, Inc., are incorporated into this Confirmation. In the event of any inconsistency between the Swap Definitions and the Equity Definitions, the Equity Definitions will govern, and in the event of any inconsistency between the Definitions and this Confirmation, this Confirmation will govern. References herein to a “Transaction” shall be deemed to be references to a “Share Option Transaction” for the purposes of the Equity Definitions and to a “Swap Transaction” for the purposes of the Swap Definitions. For purposes of this Transaction, “Warrant Style”, “Warrant Type”, “Number of Warrants” and “Warrant Entitlement” (each as defined below) shall be used herein as if such terms were referred to as “Option Style”, “Option Type”, “Number of Options” and “Option Entitlement”, respectively, in the Definitions.

This Confirmation (notwithstanding anything to the contrary herein), shall be subject to, and form part of, an agreement in the 1992 form of the ISDA Master Agreement (Multicurrency Cross Border) (the “Master Agreement” or “Agreement”) as if we had executed an agreement in such form (but without any Schedule and with elections specified in the “ISDA Master Agreement” Section of this Confirmation) on the Trade Date. In the event of any inconsistency between the provisions of that Agreement and this Confirmation, this Confirmation will prevail for the purpose of this Transaction. The parties hereby agree that the Transaction evidenced by this Confirmation shall be the only Transaction subject to and governed by the Agreement.

Net Physical Settlement:		In the event that the Counterparty elects to settle this Transaction by Net Physical Settlement, subject to “Conditions of Net Physical Settlement” below, Counterparty shall deliver to Dealer on the Settlement Date a number of Shares (the “Delivered Shares”) equal to the Share Delivery Quantity, provided that in the event that the number of Shares calculated comprises any fractional Share, only whole Shares shall be delivered and an amount in cash equal to the value of such fractional share shall be payable by the Counterparty to Dealer in lieu of such fractional Share.
Share Delivery Quantity:		For each Exercise Date, a number of Shares, as calculated by the Calculation Agent, equal to the Net Physical Settlement Amount for such Exercise Date

OTC Warrant Confirmation (amended)

		divided by the Settlement Price on the Valuation Date in respect of such Settlement Date plus an amount in cash in lieu of any fractional shares (based on the applicable Settlement Price).
Net Physical Settlement Amount:		For any Exercise Date, an amount equal to the product of (i) the Number of Warrants being exercised on the relevant Exercise Date, (ii) the Strike Price Differential for such Exercise Date and (iii) the Warrant Entitlement.
Strike Price Differential:		For any Valuation Date, (i) if the Settlement Price is greater than the Strike Price, an amount equal to the excess of such Settlement Price over the Strike Price for such Valuation Date or (ii) if such Settlement Price is less than or equal to the Strike Price, zero.
Settlement Date:		Settlement with respect to each Exercise Date shall occur on the third (3rd) Full Exchange Business Day following the final Valuation Date, provided that Dealer shall have the right to request by prior written notice to Counterparty a Settlement Date with respect to any Exercise Date and the related Share Delivery Quantity that is three (3) Full Exchange Business Days following such Exercise Date. Such request shall not unreasonably be denied.
Conditions to Net Physical Settlement:		If, in connection with or six months following delivery of Shares hereunder, Dealer notifies the Counterparty that Dealer has reasonably determined after advice from counsel that there is a considered risk that such Shares are subject to restrictions on transfer in the hands of Dealer pursuant to the rules and regulations promulgated under the Securities Act of 1933, as amended (the “Securities Act”), then Counterparty shall either (i) deliver Shares that are covered by an effective registration statement of Counterparty for immediate resale by Dealer or (ii) agree to deliver additional Shares so that the value of such Shares as determined by the Calculation Agent to reflect an appropriate liquidity discount, equals the value of the number of Shares that would otherwise be deliverable if such Shares were freely tradable upon receipt by Dealer.
		(A) If Counterparty elects to deliver Shares as described in above clause (i), then promptly following such notification from Dealer
				(a) Counterparty shall afford Dealer a reasonable opportunity to conduct a due diligence investigation with respect to Counterparty that is customary in scope for underwritten offerings of equity securities that yields a result reasonably satisfactory to Dealer;
				(b) Counterparty shall promptly make available to Dealer an effective registration statement for immediate resale (the “Registration Statement”) in form and content reasonably satisfactory to Dealer and filed pursuant to Rule 415 under the Securities Act, and such prospectuses as Dealer may reasonably request to comply with the applicable prospectus delivery requirements (the “Prospectus”) for the resale by Dealer of such number of Shares as Dealer shall reasonably specify in accordance with this paragraph, such Registration Statement to be effective and Prospectus to be current until the earliest of the date on which (1) all Delivered Shares have been sold by Dealer, (2) Dealer has advised Counterparty that it no longer requires that such Registration Statement be effective, (3) all remaining Delivered Shares could be sold by Dealer without registration pursuant to Rule 144 promulgated under the Securities Act (the “Registration Period”) or (4) Counterparty has provided a legal opinion in form and substance satisfactory to Dealer

OTC Warrant Confirmation (amended)

				(with customary assumptions and exceptions) that the Shares issuable upon exercise of these Warrants will be freely tradable under the Securities Act upon delivery to Dealer and not subject to any legend restricting transferability. It is understood that the Registration Statement and Prospectus will cover a number of Shares equal to the aggregate number of Shares (if any) reasonably estimated by Dealer to be potentially deliverable by Counterparty in connection with Net Physical Settlement hereunder (not to exceed the Maximum Deliverable Share Amount) and shall be subject to the same suspension of sales during “blackout dates” as provided in the following paragraph. Clause (B)(c) below shall apply mutatis mutandis in the event of any blackout dates occurring during Dealer’s selling efforts during the Registration Period; and
				(c) Counterparty will enter into a registration rights agreement with Dealer in form and substance reasonably acceptable to Dealer, which agreement will contain among other things, customary representations and warranties and indemnification, restrictions on sales during “blackout dates” as provided for in the registration rights agreement (the “Registration Rights Agreement”) entered into by Counterparty on or about the date hereof, provide for delivery of comfort letters and opinions of counsel and other rights relating to the registration of a number of Shares equal to the number of Delivered Shares and other Shares deliverable hereunder up to the Maximum Deliverable Share Amount.
		(B) If Counterparty elects to deliver Shares as described in above clause (ii), then promptly following such notification from Dealer
				(a) Counterparty shall afford Dealer and any potential institutional purchaser of any Shares identified by Dealer a reasonable opportunity to conduct a due diligence investigation with respect to Counterparty that is customary in scope for private placements of equity securities subject to execution of any customary confidentiality agreements;
				(b) Counterparty shall enter into an agreement (a “Private Placement Agreement”) with Dealer on commercially reasonable terms in connection with the private placement of such Shares (including any additional Shares pursuant to clause (c) below) by Counterparty to Dealer or an affiliate and the private resale of such shares by Dealer or such affiliate, substantially similar to private placement purchase agreements customary for private placements of equity securities, in form and substance commercially reasonably satisfactory to Dealer and Counterparty, which Private Placement Agreement shall include provisions relating to the indemnification of, and contribution in connection with the liability of, Dealer and its affiliates, shall provide for the payment by Counterparty of all expenses in connection with such resale, including all reasonable and documented fees and expenses of counsel for Dealer, shall contain representations, warranties and agreements of Counterparty reasonably necessary or advisable to establish and maintain the availability of an exemption from the registration requirements of the Securities Act for such resales, and shall use reasonable best efforts to provide for the delivery of accountants’ “comfort letters” to Dealer or such affiliate with respect to the financial statements and certain financial information contained in or incorporated

OTC Warrant Confirmation (amended)

				by reference into the offering memorandum prepared for the resale of such Shares;
				(c) Dealer shall sell the Delivered Shares in a commercially reasonable manner until the amount received by Dealer for the sale of the Shares (the “Proceeds Amount”) is equal to the Net Physical Settlement Amount. Any remaining Delivered Shares shall be returned to Counterparty. If the Proceeds Amount is less than the Net Physical Settlement Amount, Counterparty shall promptly deliver upon notice from Dealer additional Shares to Dealer until the dollar amount from the sale of such Shares by Dealer equals the difference between the Net Physical Settlement Amount and the Proceeds Amount. In no event shall Counterparty be required to deliver to Dealer a number of Shares greater than the Maximum Deliverable Share Amount.
		(C) Notwithstanding the foregoing: (I) if Counterparty has elected to deliver Shares as described in clause (i) above and either (a) Counterparty does not provide for the sale of the Shares under the Registration Statement as provided in the Registration Rights Agreement or (b) some Shares cannot be registered under the Registration Statement due to Rule 415(a)(4) under the Securities Act, then the provisions of sub-paragraph (B) shall apply to the extent Counterparty has not satisfied its obligations hereunder by the delivery of Shares pursuant to sub-paragraph (A). (II) If sub-paragraph (B) is applicable and Counterparty fails to satisfy its obligations under such sub-paragraph (B), then Counterparty may deliver unregistered Shares of equivalent value to the Net Physical Settlement Amount (or, if applicable, the unsatisfied portion thereof). The value of any unregistered Shares so delivered shall be discounted to reflect an appropriate liquidity discount (determined by Dealer in a commercially reasonable manner, taking into account Dealer’s policies and determinations with respect to any transfer restrictions that Dealer deems it advisable to observe in connection with sales of such Shares). (III) If some or all of the Delivered Shares cannot be used to close out stock loans in the shares of Counterparty entered into to establish or maintain short positions by Dealer in connection with this Transaction without a prospectus being required by applicable law to be delivered to such lender, then the value of any such Delivered Shares shall reflect the cost (determined by Dealer in good faith and in a commercially reasonable manner) to Dealer of trading Shares in order to close out its hedge position if any, in all cases for purposes of calculating the Delivered Shares. In no event shall Counterparty be required to top-up the delivery in cash.
Limitations on Net Physical Settlement by Counterparty:		Notwithstanding anything herein or in the Agreement to the contrary, the number of Shares that may be delivered at settlement by Counterparty shall not exceed 2,603,418 at any time (“Maximum Deliverable Share Amount”), as adjusted by Calculation Agent to account for any subdivision, stock-split, stock combination, reclassification, certain distributions, dividends and payments to holders of Counterparty’s common stock or similar dilutive or anti-dilutive event with respect to the Shares.
		Counterparty represents and warrants that the number of Available Shares as of the Trade Date is greater than the Maximum Deliverable Share Amount. Counterparty covenants and agrees that (i) Counterparty shall not take any action of corporate governance or otherwise to reduce the number of Available Shares below the Maximum Deliverable Share Amount and (ii) Counterparty shall use its reasonable efforts to cause the number of Available Shares at all times to be greater than the Maximum Deliverable Share Amount.

OTC Warrant Confirmation (amended)

		For this purpose, “Available Shares” means the number of Shares Counterparty currently has authorized (but not issued and outstanding) less the maximum number of Shares that may be required to be issued by Counterparty in connection with stock options, convertibles, and other commitments of Counterparty that may require the issuance or delivery of Shares in connection therewith.
Dividends:
Dividends:		If at any time during the period from and including the Trade Date, to but excluding the final Expiration Date, an ex-dividend date for a cash dividend occurs with respect to the Shares (an “Ex-Dividend Date”), and that dividend is different from the Regular Dividend on a per Share basis, then the Calculation Agent will adjust the Strike Price, the Number of Warrants, the Daily Number of Warrants, the Warrant Entitlement and any other variable to preserve the fair value of the Warrant after taking into account such dividend.
Regular Dividend:		Initially USD $0.06 per Share per quarter in respect of the Shares. In the event that, in any quarter, a regular quarterly Ex-Dividend Date occurs for which the amount of the corresponding cash dividend is different (the “New Dividend Amount”) from the Regular Dividend or no Ex-Dividend Date occurs (in which case the New Dividend Amount shall be zero), then following the adjustment by the Calculation Agent pursuant to “Dividends” above, the Regular Dividend shall equal the New Dividend Amount.
Extraordinary Dividends:		Any dividend other than Regular Dividends. For the avoidance of doubt, if more than one Ex-Dividend Date occurs in a quarter, the Calculation Agent shall designate any cash dividend other than a Regular Dividend as an Extraordinary Dividend and will adjust the Strike Price, the Number of Warrants, the Daily Number of Warrants, the Warrant Entitlement and any other variable to preserve the fair value of the Warrant after taking into account such dividend.
Extraordinary Events:
Consequences of Merger Events:		(a) Share-for-Share: Cancellation and Payment (Calculation Agent Determination) (b) Share-for-Other: Cancellation and Payment (Calculation Agent Determination) (c) Share-for-Combined: Cancellation and Payment (Calculation Agent Determination)
Tender Offer:		Applicable
Consequences of Tender Offers:		(a) Share-for-Share: Modified Calculation Agent Adjustment
		(b) Share-for-Other: Cancellation and Payment (Calculation Agent Determination)
		(b) Share-for-Combined: Component Adjustment

OTC Warrant Confirmation (amended)

		With respect to any Extraordinary Events hereunder, upon the occurrence of Cancellation and Payment in whole or in part, the parties agree that the amount to be paid, in accordance with the Equity Definitions, shall constitute a Transaction Early Termination Amount, subject to satisfaction by the payment or delivery of Shares or cash as set forth in the Early Termination section below.
Nationalization, Insolvency or Delisting:		Cancellation and Payment (Calculation Agent Determination) (subject to satisfaction by payment or delivery of Shares or cash as set forth in “Early Termination” below). In addition to the provisions of Section 12.6(a)(iii) of the Equity Definitions, it will also constitute a Delisting if the Shares are not listed on a United States national securities exchange or approved for quotation and trading on a national automated dealer quotation system or established automated over-the-counter trading market in the United States or ceases to be so traded or quoted in contemplation of a delisting or withdrawal of approval; if the Shares are immediately re-listed, re-traded or re-quoted on any such exchange or quotation system, such exchange or quotation system shall thereafter be deemed to be the Exchange.

Non-Reliance:		Applicable
Agreements and
Acknowledgments Regarding
Hedging Activities:		Applicable
Additional Acknowledgments:		Applicable
Other Provisions:
Additional Agreements:		If Counterparty would be obligated to pay cash to Dealer pursuant to the terms of this Confirmation or the Agreement for any reason without having had the right (other than pursuant to this paragraph) to elect to deliver Shares in satisfaction of such payment obligation, then Counterparty may elect to deliver to Dealer a number of Shares (whether registered or unregistered) having a cash value equal to the amount of such payment obligation. Such number of Shares to be delivered shall be the number of Shares, determined by the Calculation Agent, sufficient for Dealer to realize the cash equivalent of such payment obligation from proceeds of the sale of such number of Shares over a reasonable period of time taking into account any applicable discount (determined in a commercially reasonable manner) to reflect any restrictions on transfer as well as the market value of the Shares. Settlement relating to any delivery of Shares pursuant to this paragraph shall occur within a reasonable period of time. The number of Shares delivered pursuant to this paragraph shall not exceed the Maximum Deliverable Share Amount and shall be subject to the provisions under “Early Termination” hereof regarding Proceeds Amount and the provisions set forth in subsection (c) under “Additional Agreements, Representations and Covenants of Counterparty, Etc.” below.
Early Termination:		Notwithstanding any provision to the contrary, upon the designation of an Early Termination Date or the occurrence of Cancellation and Payment in whole or in part hereunder, Counterparty’s payment obligation in respect of this Transaction (which shall, in the case of an Early Termination Date be determined in

OTC Warrant Confirmation (amended)

		accordance with Second Method and Loss) (the “Transaction Early Termination Amount”) may, at the option of Counterparty, be satisfied by the delivery of a number of Shares equal to the Transaction Early Termination Amount divided by the Termination Price (“Early Termination Stock Settlement”); provided, however, that Counterparty must notify Dealer of its election of Early Termination Stock Settlement by the close of business on the day that is two Exchange Business Days following the day that the notice designating the Early Termination Date, or notice that an Extraordinary Event has resulted in the cancellation or termination of the Transaction in whole or in part, is effective. “Termination Price” means the market value per Share on the Early Termination Date, as determined by the Calculation Agent in a commercially reasonable manner taking into account any applicable discount to reflect any restrictions on transfer.
		A number of Shares calculated as being due in respect of any Early Termination Stock Settlement will be deliverable on the third Clearance System Business Day following the date that notice specifying the number of Shares deliverable is effective; provided that, if Counterparty is delivering Shares as a result of a Merger Event, the Settlement Date for such delivery will be immediately prior to the effective time of the Merger Event and the Shares will be deemed delivered at such time such that Dealer will be a holder of the Shares prior to such effective time. Section 6(d)(i) of the Agreement is hereby amended by adding the following words after the word “paid” in the fifth line thereof: “or any delivery is to be made, as applicable.”
		On or prior to the Early Termination Date or date on which notice that an Extraordinary Event has resulted in the cancellation or termination of the Transaction in whole or in part is effective, as applicable, if Early Termination Stock Settlement is elected and if so requested by Dealer upon advice of counsel, Counterparty shall (subject to its right to make the election described in the immediately succeeding paragraph) enter into a registration rights agreement with Dealer in form and substance reasonably acceptable to Dealer which agreement will contain among other things, customary representations and warranties and indemnification, restrictions on sales during “blackout dates” as provided for in the Registration Rights Agreement and shall satisfy the conditions contained therein and Counterparty shall file and diligently pursue to effectiveness a Registration Statement pursuant to Rule 415 under the Securities Act. If and when such Registration Statement shall have been declared effective by the Securities and Exchange Commission, Counterparty shall have made available to Dealer such Prospectuses as Dealer may reasonably request to comply with the applicable prospectus delivery requirements for the resale by Dealer of such number of Shares as Dealer shall specify (or, if greater, the number of Shares that Counterparty shall specify). Such Registration Statement shall be effective and Prospectus shall be current until the earliest of the date on which (i) all Shares delivered by Counterparty in connection with an Early Termination Date have been sold, (ii) Dealer has advised Counterparty that it no longer requires that such Registration Statement be effective or (iii) all remaining Shares could be sold by Dealer without registration pursuant to Rule 144 promulgated under the Securities Act (the “Termination Registration Period”). It is understood that the Registration Statement and Prospectus will cover a number of Shares equal to the Number of Shares plus the aggregate number of Shares (if any) reasonably estimated by Dealer to be potentially deliverable by Counterparty in connection with Early Termination Stock Settlement hereunder, but in no event exceeding the Maximum Deliverable Share Amount. On each day during the Termination Registration Period Counterparty shall represent that each of its filings under the

OTC Warrant Confirmation (amended)

		Securities Act, the Exchange Act or other applicable securities laws that are required to be filed have been filed and that, as of the respective dates thereof and as of the date of this representation, they do not contain any untrue statement of a material fact or omission of a material fact required to be stated therein or necessary to make the statements made, in the light of the circumstances under which they were made, not misleading.
		If Counterparty elects not to deliver Shares subject to an effective Registration Statement (or if some or all of the Shares delivered cannot be used to close out stock loans in the shares of Counterparty entered into to establish or maintain short positions by Dealer in connection with this Transaction without a prospectus being required by applicable law to be delivered to such lender), the provisions of sub-paragraphs (B) and (C) set forth above under “Conditions to Net Physical Settlement” shall apply, mutatis mutandis, as if the Net Physical Settlement Amount were the Transaction Early Termination Amount. In no event shall Counterparty be required to deliver to Dealer a number of Shares greater than the Maximum Deliverable Share Amount.
Compliance With Securities Laws:		Each party acknowledges that the offer and sale of the Transaction to it is intended to be exempt from registration under the Securities Act by virtue of Section 4(2) thereof. Accordingly, each party represents and warrants to the other party that (i) it has the financial ability to bear the economic risk of its investment in the Transaction and is able to bear a total loss of its investment, (ii) it is an “accredited investor” as that term is defined in Regulation D as promulgated under the Securities Act and (iii) the disposition of the Transaction is restricted under this Confirmation, the Securities Act and state securities laws.
		Counterparty further represents and warrants that:
		(a) Counterparty is not entering into this Transaction to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for Shares);
		(b) Counterparty represents and acknowledges that as of the date hereof and without limiting the generality of Section 13.1 of the Equity Definitions, Dealer is not making any representations or warranties with respect to the treatment of the Transaction under FASB Statements 149 or 150, EITF Issue No. 00-19 (or any successor issue statements) or under FASB’s Liabilities & Equity Project;
		(c) Counterparty is not, and after giving effect to the Transaction contemplated hereby, will not be, an “investment company” as such term is defined in the Investment Company Act of 1940, as amended;
		(d) As of the Trade Date and each date on which a payment or delivery is made by Counterparty hereunder, (i) the assets of Counterparty at their fair valuation exceed the liabilities of Counterparty, including contingent liabilities; (ii) the capital of Counterparty is adequate to conduct its business; and (iii) Counterparty has the ability to pay its debts and other obligations as such obligations mature and does not intend to, or believe that it will, incur debt or other obligations beyond its ability to pay as such obligations mature.

Agreement Regarding Shares:		Counterparty agrees that, in respect of any Shares delivered to Dealer, such Shares shall be, upon such delivery, duly and validly authorized, issued and outstanding, fully paid and non-assessable and subject to no adverse claims of any other party. The issuance of such Shares does not and will not require the consent, approval, authorization, registration or qualification of any government authority, except such as shall have been obtained on or before the delivery date of any Shares or as may be required in connection with any Registration Statement filed with respect to any Shares.
Bankruptcy Rights:		In the event of Counterparty’s bankruptcy, Dealer’s rights in connection with this Transaction shall not exceed those rights held by common shareholders. For the avoidance of doubt, the parties acknowledge and agree that Dealer’s rights with respect to any other claim arising from this Transaction prior to Counterparty’s bankruptcy shall remain in full force and effect and shall not be otherwise abridged or modified in connection herewith.

Transfer:		Neither party may transfer its rights or delegate its obligations under this Transaction without the prior written consent of the other party, except that Dealer, after payment in full of the Premium, may assign its rights and delegate its obligations hereunder, in whole or in part, to any other person (an “Assignee”) without the prior consent of the Counterparty, effective (the “Transfer Effective Date”) upon delivery to Counterparty of an executed acceptance and assumption by the Assignee (an “Assumption”) of the transferred obligations of Dealer under this Transaction (the “Transferred Obligations”). Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities to or from Counterparty, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities and otherwise to perform Dealer’s obligations in respect of this Transaction and any such designee may assume such obligations.

Notwithstanding the foregoing, recourse to Buyer shall be limited to recoupment of Seller’s monetary damages and Seller hereby waives any right to seek specific performance by Buyer of its obligations

Indemnity:		Seller agrees to indemnify Dealer, its Affiliates and their respective directors, officers, agents and controlling parties (each such person being an “Indemnified Party”) from and against any and all losses, claims, damages and liabilities, joint and several, to which such Indemnified Party may become subject because of a breach of any representation or covenant hereunder, in the Agreement or any other agreement relating to the Agreement or Transaction and will reimburse Indemnified Party for all reasonable expenses (including reasonable legal fees and expenses) as they are incurred in connection with the investigation of, preparation for, or defense of, any pending or threatened claim or any action or proceeding arising therefrom, whether or not such Indemnified Party is a party thereto. Seller will not be liable under the foregoing Indemnity provision to the extent that any loss, claim, damage, liability or expense is found in a final judgment by a court to have resulted from Dealer’s gross negligence or willful misconduct.

Additional Agreements, Representations and Covenants of Counterparty, Etc.:

(a)

Counterparty hereby represents and warrants to Dealer, on each day from the Trade Date to and including the earlier of (i) July 29, 2007 (ii) the date by which Dealer is able to initially complete a hedge of its position created by this Transaction, that:

	(1)		it will not, and will not permit any person or entity subject to its control to, bid for or purchase Shares during such period except pursuant to transactions or arrangements which have been approved by Dealer or an affiliate of Dealer; and
	(2)		it has publicly disclosed all material information necessary for it to be able to purchase or sell Shares in compliance with applicable federal securities laws.

(b)		No collateral shall be required by either party for any reason in connection with this Transaction.
(c)		Notwithstanding anything to the contrary herein, Dealer shall not be entitled to exercise any Warrant or receive any Shares deliverable hereunder, and Automatic Exercise shall not apply with respect to any Warrant to the extent (but only to the extent) that after such receipt of any Shares upon the exercise of such Warrant or otherwise hereunder Dealer, or its ultimate parent entity would, directly or indirectly, be the beneficial owner (as such term is defined for purposes of Section 13(d) of the Exchange Act) at any time of more than 8.0 percent of the class of the Counterparty’s outstanding equity securities that is comprised of the Shares (an “Excess Share Owner”).
		Dealer shall provide prior notice to Counterparty if the exercise of any Warrant or delivery of Shares hereunder would cause Dealer to become directly or indirectly, an Excess Share Owner; provided that the failure of Dealer to provide such notice shall not alter the effectiveness of the provisions set forth in the preceding sentence and any purported exercise or delivery in violation of such provisions shall be void and have no effect. If any delivery owed to Dealer hereunder is not made, in whole or in part, as a result of this provision, Counterparty’s obligation to make such delivery shall not be extinguished and Counterparty shall make such delivery as promptly as practicable after Dealer gives notice that such delivery would not result in Dealer being an Excess Share Owner.
		If Dealer is not entitled to exercise any Warrant because such exercise would cause Dealer to become, directly or indirectly, an Excess Share Owner and Dealer thereafter disposes of Shares owned by it or any action is taken that would then permit Dealer to exercise such Warrant without such exercise causing it to

OTC Warrant Confirmation (amended)

become, directly or indirectly, an Excess Share Owner, then Dealer shall provide notice of the taking of such action to Counterparty and such Warrant shall then become exercisable by Dealer to the extent such Warrant is otherwise or had otherwise become exercisable hereunder. In such event, the Expiration Date with respect to such Warrant shall be the date on which Counterparty receives such notice from Dealer, and the related Settlement Date shall be as soon as reasonably practicable after receipt of such notice but no more than three (3) Exchange Business Days thereafter (but in no event shall the Settlement Date occur prior to the date on which it would have otherwise occurred but for the provisions of this subsection); provided that the related Net Physical Settlement Amount shall be the same as the Net Physical Settlement Amount but for the provisions of this subsection. In addition, within 30 calendar days of any Settlement Date, Counterparty shall use its reasonable efforts to refrain from activities that could reasonably be expected to result in Dealer’s ownership of Shares exceeding 10% of all issued and outstanding Shares.

     (ii) any “person” or “group” (as such terms are used in Sections 13(d) and 14(d) of the Exchange Act) is or becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act, except that a person shall be deemed to have beneficial ownership of all shares that such person has the right to acquire, whether such right is exercisable immediately or only after the passage of time), directly or indirectly, of voting stock representing 50% or more of the total voting power of all outstanding voting stock of the Issuer;

     (iii) the Issuer consolidates with, or merges with or into, another person or the Issuer sells, assigns, conveys, transfers, leases or otherwise disposes of all or substantially all of its assets to any person, other than

     (iv) during any consecutive two-year period, the Continuing Directors cease for any reason to constitute a majority of the board of directors of the Issuer. “Continuing Directors” means, as of any date of determination, any member of the board of directors of the Issuer who was (a) a member of such board of directors on the Effective Date or (b) nominated for election or elected to such board of directors with the approval of a majority of the Continuing Directors who were members of such board at the time of such nomination or election; or

     (v) the adoption of a plan of liquidation or dissolution of the Issuer.

Notwithstanding the foregoing, a transaction set forth in clause (ii), (iii) or (iv) above will not constitute an Additional Termination Event if 100% of the consideration for the Shares (excluding cash payments for fractional shares and cash payments made in respect of dissenters’ appraisal rights) in such transaction or transactions consists of common stock and any associated rights listed on a United States national securities exchange or quoted on a national automated dealer quotation system, or which will be so traded or quoted when issued or exchanged in connection with such transaction or transactions otherwise constituting an Additional Termination Event under clauses (ii), (iii) or (iv) above.
