II. Settlement A. Notice and Settlement Amount 1. The Company may on any Exchange Trading Day up to and including the Maturity Date, upon the giving of five (5) Business Days telephonic notice to UBS, settle all or part of this Transaction. Such notice shall specify: (i) the number of Underlying Shares subject to such settlement (the "Settlement Shares"), (ii) the settlement method (Cash, Stock or Net Stock Settlement, as such methods are described below), and (iii) the date upon which such settlement shall begin ("Day S"), which must be an Exchange Trading Day; provided however, that if in UBS' reasonable judgment the settlement of the Settlement Shares would potentially violate or contravene any legal or regulatory prohibition or requirement applicable to UBS or cause UBS to contravene any established UBS corporate policy or compliance policy (other than any corporate policy limiting the amount of UBS's investment in another entity), then UBS shall at least three (3) Business Days prior to the proposed Day S, notify the Company telephonically (confirmed by writing) of any such impediment and its estimate of the period during which such impediment will preclude UBS' ability to settle all or part of this Transaction, in which case the Company may upon telephonic notice to UBS at least one (1) Exchange Trading Day prior to the proposed Day S withdraw its settlement notice. Such notice shall be effective only if the notice requirements specified above are fulfilled, provided, that if no settlement method is specified, then the settlement method shall be deemed to be Cash Settlement. In the case of any partial settlement ("Partial Settlement"), following such settlement the number of Underlying Shares to which this Transaction shall relate shall be adjusted by subtracting the number of Settlement Shares from the number of Underlying Shares to which the Transaction related (as the same may have been adjusted prior to such Partial Settlement) immediately prior to such partial settlement. The Settlement Shares shall not be subject to forward accretion and shall be treated separately from the remaining Underlying Shares, during any Unwind Period. 2. On Day S, the Settlement Price for the Settlement Shares and the Settlement Amount shall be determined for Day S. 3. The Settlement Amount shall be settled pursuant to the settlement method (B, C, or D of this Article II) selected by the Company in its sole discretion. 4. If settlement with respect to the Settlement Shares (this section does not apply for Interim Net Stock Settlement) shall occur on or before the 180th day following the Effective Date, then the Settlement Price for purposes of such settlement shall be increased by any positive amount, calculated by UBS as follows: -2- Forward Stock Purchase Spread x Forward Price x (180 - calendar days since Trade Date) -------------------------------------- 360 5. It shall be a condition precedent to any right of the Company to elect Stock Settlement (II. C. below) or Net Stock Settlement (II. D. below), that the Company must (i) notify UBS of such election at least 5 Business Days prior to Day S and (ii) prior to Day S, cause to be filed with the Securities and Exchange Commission (the "Commission") and cause to become effective under the Securities Act of 1933, as amended (the "Securities Act") a resale registration statement covering all Common Shares to be delivered by the Company to UBS LLC for the account of UBS in effecting such Stock Settlement or Net Stock Settlement, such registration statement to include one or more preliminary prospectuses, prospectuses, and any amendments and supplements thereto such that any preliminary prospectus or prospectus, as amended or supplemented, shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances under which they are made The Company further agrees that it will cause any such Registration Statement to remain in effect until the earliest of the date on which (i) all Common Shares issued pursuant hereto and not required to be delivered to the Company hereunder have been sold by UBS LLC for the account of UBS and UBS agrees to notify the Company of such fact, within two (2) Business Days of its occurrence, (ii) UBS LLC for the account of UBS is able to sell the Common Shares subject thereto under Rule 144(k), or (iii) UBS has advised the Company that it no longer requires that such registration statement be effective. B. Cash Settlement The Company shall settle by delivering cash in an amount equal to the Settlement Amount in exchange for the Settlement Shares ("Cash Settlement") on the Exchange Trading Day immediately succeeding Day S. UBS LLC for the account of UBS shall deliver the Settlement Shares to the Company on the Exchange Trading Day immediately succeeding Day S upon receipt of such Cash Settlement. C. Stock Settlement If the Company elects to meet its payment obligations by delivering Common Shares in exchange for the Settlement Shares ("Stock Settlement"), the number of Common Shares to be delivered (the "Stock Settlement Shares") shall be equal to (a) the Settlement Amount divided by (b) the Stock Settlement Unwind Price. The mechanics for settlement are set forth in II. E.2. below and Article V. D. Net Stock Settlement If the Company determines that it will elect to meet its payment obligations under II.A. or its delivery obligations under III.A. on a net stock basis ("Net Stock Settlement"), the number of net stock settlement shares (the "Net Stock Settlement Shares") shall equal: i) the number of Settlement Shares, times ii) the Settlement Price minus the Stock Settlement Unwind Price, divided by iii) the Stock Settlement Unwind Price. If such calculation yields a negative number, this shall indicate the number of Common Shares to be delivered from UBS LLC for the account of UBS to the Company. The mechanics for settlement are set forth in II. E. below and Article V. -3- Forward Stock Purchase E. Stock and Net Stock Settlement Mechanics 1. Preliminary Stock Settlement. If the Company has chosen Stock Settlement, the Company shall deliver to UBS LLC for the account of UBS, by 11:00 a.m. on Day S, that number of Common Shares, registered, for resale under an effective registration statement (the "Preliminary Stock Settlement Shares"), equal to the product of (i)(a) the Settlement Amount divided by (b) the closing price of the Common Shares on the Exchange Trading Day immediately preceding Day S, times (ii) 110%.

(i) if Stock Settlement Shares are greater than the sum of (a) Preliminary Stork Settlement Shares plus (b) any shares previously delivered pursuant to this settlement under this subparagraph (i), then the Company shall deliver that number of registered, freely tradable Common Shares equal to the difference between Stock Settlement Shares and Preliminary Stock Settlement Shares to UBS LLC for the account of UBS, and (ii) on the final day of the Unwind Period, if the sum of (a) Preliminary Stock Settlement Shares plus (b) any shares previously delivered pursuant to this settlement under this subparagraph (i) are greater than Stock Settlement Shares, then UBS LLC, for the account of UBS, shall deliver Common Shares equal to the difference between the sum of (a) and (b) above and Stock Settlement Shares to the Company's Margin Account, (b) For Net Stock Settlement: Net Stock Settlement Shares shall be calculated as if such Exchange Trading Day were Day S except that (a) there shall be no adjustment to the Settlement Amount and (b) for purposes of calculating the Stock Settlement Unwind Price, the Unwind Period shall be deemed to have ended on the Exchange Trading Day on which the calculation is made.

E. 1. above), and deliver all such Common Shares to the Company with the dollar value of all fractional shares settled in cash. 6. In the event of Stock or Net Stock Settlement (this section does not apply for Interim Net Stock Settlement), the Company shall pay an unwind accretion fee, in cash or stock, calculated in accordance with the following formula: Settlement Amount x (days in Unwind Period) x [1 month USD LIBOR + Spread] --------------------- -------------------------- 2 360 7. In the event of Stock or Net Stock Settlement (this section does not apply for Interim Net Stock Settlement), the Company shall pay a placement fee to UBS LLC for the account of UBS calculated as: Settlement Amount x 0.50% III.

On each Reset Date, if the Forward Price exceeds the closing price of the Common Shares on such Reset Date, on the Business Day following the Fifth Exchange Trading Day thereafter the Company shall deliver Common Shares registered for resale by URS to UBS LLC (if the Company is restricted by law or regulation or self-regulatory requirements or related policies and procedures, whether or not such requirements, policies or procedures are imposed by law directly or have been voluntarily adopted by the Company to insure compliance with applicable laws or in its reasonable judgment is otherwise unable or unwilling to deliver registered Common Shares, see III.B. below) for the account of UBS equal to the Interim Settlement Shares. B. In the event that the Company fails to deliver registered shares pursuant to Paragraph III.A. due to an inability described in such paragraph, the Company shall deliver cash collateral in an amount equal to the market value of the Interim Settlement Shares specified in III.A. to a collateral account at UBS. Such collateral account will earn interest at USD LIBOR for a designated maturity of 1 month, adjusted for any interest breakage costs (whether positive or negative). All other aspects of Interim Net Stock Settlement shall be unaffected. At the Company's option, upon delivering an effective resale registration statement to UBS LLC for the account of UBS, the Company may deliver freely salable registered shares to UBS equal in salable market value, based on closing market prices during a commercially reasonable valuation period, to the value of the collateral held in the collateral account at UBS.

If the Company fails to deliver an effective resale registration statement within 90 days of the Trade Date, until an effective resale registration statement is provided and an Interim Net Stock Settlement can be effected, the Company shall deliver cash collateral in an amount calculated as specified in III.A. to a collateral account at UBS. Such collateral account will earn interest at USD LIBOR for a designated maturity of 1 month, adjusted for any interest breakage costs.
