Adjustments

Section 7.1. Dilution Adjustments. Following the declaration by the Company of the terms of any Potential Adjustment Event, Buyer will determine whether such Potential Adjustment Event would have a dilutive or concentrative effect on the theoretical value of the Common Stock and, if so, Buyer will (i) calculate the corresponding adjustment, if any, to be made to any one or more of the Base Amount, the Settlement Ratio, the Cap Level, the Floor Level, any Closing Price and any other variable relevant to the settlement terms of this Agreement (including, without limitation, the amount or type of property to be delivered hereunder) as Buyer determines appropriate to account for that dilutive or concentrative effect and (ii) determine the effective date of that adjustment. Buyer may (but need not) determine the appropriate adjustment by reference to the adjustment in respect of such Potential Adjustment Event made by an options exchange to options on the Common Stock traded on that options exchange or, if there are no options on the Common Stock traded on any options exchange, by reference to the rules of and precedents set by any such options exchange.

For these purposes, “Potential Adjustment Event” means the declaration by the Company of the terms of any of the following:

(a)  A subdivision, consolidation or reclassification of shares of Common Stock (other than a Merger Event), or a free distribution or dividend of any shares of Common Stock to existing holders of Common Stock by way of bonus, capitalization or similar issue.

(b)  A distribution or dividend to existing holders of Common Stock of (i) shares of Common Stock; or (ii) other share capital or securities granting the right to payment of dividends and/or the proceeds of liquidation of the Company equally or proportionately with such payments to holders of Common Stock; or (iii) any rights or warrants to purchase securities described in (i) or (ii) of this paragraph (b) for payment (cash or other) at less than the prevailing market price as determined by Buyer.

(c)  A dividend or distribution consisting of any property except for (y) securities of a type described in paragraph (b) of this Section 7.1, or (z) cash dividends and distributions on shares of Common Stock. However, cash dividends and distributions on shares of Common Stock that are either (A) Excess Cash Dividends, (B) Extraordinary Cash Dividends or (C) consideration in connection with a Merger Event are subject to special treatment as described below. For purposes of clarification:

(d)  A call in respect of shares of Common Stock that are not fully paid.

(e)  A repurchase by the Company of shares of Common Stock, whether out of profits or capital and whether the consideration for such repurchase is cash, securities or otherwise.

(f)  Any other similar event that may have a dilutive or concentrative effect on the theoretical value of the Common Stock.

Section 7.2. Merger Events; Nationalization; Insolvency.

(a)  If any Merger Event shall be announced prior to the Settlement Date (regardless of whether the Merger Date associated therewith occurs prior to or after the Settlement Date), Buyer will determine whether such Merger Event, if consummated, would have an economic effect on the transaction contemplated by this Agreement and, if so, Buyer will calculate the corresponding adjustment, if any, to be made to any one or more of the Base Amount, the Settlement Ratio, the Cap Level, the Floor Level, any Closing Price, and any other variable relevant to the settlement terms of this Agreement (including, without limitation, the amount or type of property to be delivered hereunder) as Buyer determines appropriate to account for such economic effect. The parties agree that any such adjustment, if not made sooner, shall be made by Buyer upon the earlier of (i) the Merger Date and (ii) the Maturity Date. “Merger Event” means any (A) reclassification, change or other offer of or for the Common Stock that results in a transfer of or an irrevocable commitment to transfer 20% or more of the outstanding shares of Common Stock or (B) consolidation, amalgamation or merger of the Company with or into another entity (other than a consolidation, amalgamation or merger in which the Company is the continuing entity and which results in reclassification or change of less than 20% of the outstanding shares of Common Stock). “Merger Date” means, in respect of any Merger Event, the date upon which holders of the necessary number of shares of Common Stock to constitute a Merger Event have agreed or have irrevocably become obligated to transfer their shares of Common Stock.

(b)  If, prior to the Settlement Date, (i) all the outstanding shares of Common Stock or all the assets or substantially all the assets of the Company are nationalized, expropriated or are otherwise required to be transferred to any governmental agency, authority or entity (a “Nationalization”); or (ii) by reason of the voluntary or involuntary liquidation, bankruptcy or insolvency of or any analogous proceeding affecting the Company (an “Insolvency”): (A) all of the outstanding shares of Common Stock are required to be transferred to a trustee, liquidator or other similar official; or (B) holders of shares of Common Stock become legally prohibited from transferring them, then, in any such event, Buyer shall have the right, upon becoming aware of such event, to notify Seller of such event and terminate this Agreement as of a date set forth in such notice, following which Seller shall make a payment to Buyer as provided in Section 7.3.

Section 7.3. Payments on Termination. Following termination of this Agreement as a result of any Nationalization or Insolvency as provided in Section 7.2(b), Buyer shall determine the amount (“Termination Amount”) of the cash payment to be made by Seller to Buyer in settlement of this Agreement. The Termination Amount shall equal the Acceleration Value (calculated, for purposes of this Section 7.3, as if the Termination Date were the Acceleration Date, calculated on the basis of, in addition to the factors indicated in Section 8.1, a value ascribed to the Common Stock equal to the consideration, if any, paid or to be paid in respect of the Common Stock at the time of the Nationalization or Insolvency). As promptly as reasonably practicable after calculation of the Acceleration Value, Buyer shall deliver to Seller a notice (“Termination Amount Notice”) specifying the Termination Amount. Not later than three Business Days following delivery of a Termination Amount Notice by Buyer, Seller shall make a cash payment, by wire transfer of immediately available funds to an account designated by Buyer, to Buyer in an amount equal to the Termination Amount.

“Termination Date” means (i) in respect of a Nationalization, the date of the first public announcement of a firm intention to nationalize, and (ii) in respect of an Insolvency, the earlier of the date the shares of Common Stock are required to be transferred to a trustee, liquidator or other similar official or the date the holders of shares of Common Stock become legally prohibited from transferring the Common Stock that, in the case of a Nationalization or an Insolvency (whether or not amended or on the terms originally announced), leads to the Nationalization or the Insolvency, as the case may be, in each case as determined by Buyer.

Section 7.4 Cash Dividends.

(a)            Seller shall be entitled to retain any Ordinary Cash Dividend it receives.

(b)            If there is an Excess Cash Dividend, Seller shall, promptly (but in any case within seven days) following the date on which such Excess Cash Dividend is paid to holders of Common Stock generally, pay to Buyer an amount in cash equal to the per share amount of the Excess Cash Dividend multiplied by the Base Amount.

(c)            If an Extraordinary Cash Dividend with an ex-dividend date occurring during the Dividend Period is paid on the Common Stock:

Seller shall make any such payment promptly (but in any case, within seven days) following the date on which such Extraordinary Cash Dividend is paid to holders of Common Stock generally.

Section 7.5. Miscellaneous. For the avoidance of doubt, for the purposes of this Section, Article 7 generally and Section 8.1(f), without limitation as to applicability to any other provision of this Agreement or the Pledge Agreement, unless the context otherwise requires, any reference to Common Stock shall be deemed to apply severally to any class of securities, cash or other property that shall have been distributed with respect to the Common Stock or into which Common Stock shall have been converted or otherwise exchanged (whether as a result of a Potential Adjustment Event, a Merger Event or otherwise) and any such other class of securities, cash or other property resulting from the successive application of this sentence.

Section 8.1. Acceleration. If one or more of the following events (each an “Event of Default”) shall occur:

(a)  any legal proceeding shall have been instituted or any other event shall have occurred or condition shall exist that in Buyer’s judgment could have a material adverse effect on the financial condition of Seller or on Seller’s ability to perform Seller’s obligations hereunder, or that calls into question the validity or binding effect of any agreement of Seller hereunder or under the Pledge Agreement;

(b)  Seller makes an assignment for the benefit of creditors, files a petition in bankruptcy, is adjudicated insolvent or bankrupt, petitions or applies to any tribunal for any receiver of or any trustee for Seller or any substantial part of Seller’s property, commences any proceeding relating to Seller under any reorganization, arrangement, readjustment of debt, dissolution or liquidation law or statute of any jurisdiction, whether now or hereafter in effect, or there is commenced against or with respect to Seller or any substantial portion of its property any such proceeding and an order for relief is issued or such proceeding remains undismissed for a period of 30 days;

(c)  at any time, any representation made or repeated or deemed to have been made or repeated by Seller under this Agreement or the Pledge Agreement or any certificate delivered pursuant hereto or thereto would be incorrect or misleading in any material respect if made or repeated as of such time;

(d)  Seller fails to fulfill or discharge when due any of its obligations, covenants or agreements under or relating to this Agreement or the Pledge Agreement, including Seller’s obligations to deliver shares of Common Stock (or security entitlements in respect thereof) or cash on the Settlement Date;

(e)  due to the adoption of, or any change in, any applicable law after the date hereof, or due to the promulgation of, or any change in, the interpretation by any court, tribunal or regulatory authority with competent jurisdiction of any applicable law after the date hereof, it becomes unlawful for Seller to perform any absolute or contingent obligation to make payment or delivery hereunder or to comply with any other material provision of this Agreement or the Pledge Agreement;

(f)  in the reasonable judgment of Buyer, it becomes impracticable to freely trade (long or short) in the market for the Common Stock (or security entitlements in respect thereof), or any other securities deliverable hereunder as a result of the application of Article 7, or borrow on reasonable terms the Common Stock (or security entitlements in respect thereof), or any other securities deliverable hereunder as a result of the application of Article 7; or

(g)  a Collateral Event of Default within the meaning of the Pledge Agreement shall occur

then, upon the delivery of written notice to Seller from Buyer at any time following an Event of Default, an “Acceleration Date” shall be deemed to have occurred, and Seller shall become obligated to deliver immediately upon receipt of the Acceleration Amount Notice (as defined below) a number of shares of Unrestricted Stock equal to the Acceleration Amount; provided that if Buyer proceeds to realize upon any collateral pledged under the Pledge Agreement and to apply the proceeds of such realization as provided in paragraph second of Section 10(d) thereof, then, to the extent of such application of proceeds, Seller’s obligation to deliver Unrestricted Stock pursuant to this paragraph shall be deemed to be an obligation to deliver an amount of cash equal to the aggregate Market Value of such Unrestricted Stock on the Acceleration Date. “Acceleration Amount” means the quotient obtained by dividing: (i) the Acceleration Value, as defined below, by (ii) the Market Value per share of the Common Stock on the Acceleration Date.

“Acceleration Value” means an amount determined by Buyer representing the fair value to Buyer of an agreement with terms that would preserve for Buyer the economic equivalent of the payments and deliveries that Buyer would, but for the occurrence of the Acceleration Date, have been entitled to receive after the Acceleration Date under Article 2 (taking into account any adjustments pursuant to Section 7.1 that may have been calculated on or prior to the Acceleration Date). Buyer shall calculate such amount based on the following factors (and such other factors as it deems appropriate): (i) the volatility of the Common Stock; (ii) dividends on the Common Stock; and (iii) prevailing interest rates.

As promptly as reasonably practicable after calculation of the Acceleration Value, Buyer shall deliver to Seller a notice (“Acceleration Amount Notice”) specifying the Acceleration Amount of shares of Common Stock (or security entitlements in respect thereof) required to be delivered by Seller.

Buyer and Seller agree that the Acceleration Value is a reasonable pre-estimate of loss and not a penalty. Such amount is payable for the loss of bargain and, if Seller delivers the Acceleration Amount in the manner provided above, Buyer will not be entitled to recover any additional damages as a consequence of loss resulting from an Event of Default, a Nationalization or an Insolvency.
