Scope of Transaction Coverage Relating to the Auction Terms
Will the Auction Terms affect my single name LCDS trades?
Yes. Single name LCDS trades documented under either (a) the Bullet Syndicated Secured Loan Credit Default Swap Standard Terms Supplement (the “Bullet LCDS Standard Terms”) published by ISDA on April 5, 2010 or (b) the Syndicated Secured Loan Credit Default Swap Standard Terms Supplement (the “LCDS Standard Terms”) published by ISDA on May 22, 2007 will be subject to the Auction Terms. Transactions in category (b) would include LCDS transactions documented under the LCDS Standard Terms published by ISDA on June 8, 2006, provided both parties adhered to the ISDA LCDS Protocol. Thus, single name LCDS trades on First Lien Loans documented on this basis will be subject to the procedures set forth in the Auction Terms.

Auction
Who runs the auction?
The auction will be administered by Creditex and Markit and not by ISDA.

When is the auction?
The auction will be held on Tuesday September 21, 2010. Details of the auction results will be posted at www.creditfixings.com .

Physical Settlement through the auction
I want to physically settle through the auction, what do I have to do?
Parties who wish to deliver or receive Deliverable Obligations may place a Physical Settlement Request with a Participating Bidder.  A Physical Settlement Request is an order to sell or buy Deliverable Obligations at the Final Price.  A Physical Settlement Request must be submitted in the form of the Customer Physical Settlement Request Letter set out in Exhibit 2 to the Auction Terms.  Please click here for a form of Customer Physical Settlement Request Letter. Parties wishing to submit a Customer Physical Settlement Request Letter should contact their dealer that is acting as a Participating Bidder in advance of the auction. A list of Participating Bidders is available on our website.

Following the auction, each party that submitted a Physical Settlement Buy or Sell Request that is matched in the auction will be treated as if they had entered into an agreement with the relevant Participating Bidder on terms equal to a Representative  Auction-Settled Transaction (RAST). Parties that submitted a Physical Settlement Sell Request must send a Notice of Physical Settlement to the relevant Participating Bidder, specifying which Deliverable Obligations they will deliver in settlement of that transaction.  A form of Notice of Physical Settlement is contained as an exhibit to the Auction Terms.  The deadline for sending this notice is specified as the "Notice of Physical Settlement Date" in the Auction Terms.

Cash Settlement Date and Accruals
When is the cash settlement date?
The cash settlement date (referred to in the auction terms as the "Auction Settlement Date") will be September 28, 2010.

How are accruals calculated?
Depending on the timing of the auction settlement process relative to standard payment dates for LCDS contracts, accruals are calculated and settled using either a "stub accrual" methodology or a "full coupon and rebate" methodology. Please see below for the methodology applied to the Auction and further explanation of these methodologies.

For Boston Generating LLC, the 'full coupon and rebate' methodology will apply. The day after the Common Event Determination Date is August 20, 2010, and the standard payment date is September 20, 2010. ''Full coupon'' is payable on September 20, 2010, and 31 days' accrual will be rebated, EXCEPT for transactions that matured on September 20, 2010, for which 32 days' accrual will be rebated.

Under the "stub accrual" methodology, the Fixed Rate in respect of the relevant Reference Entity accrues from and including the previous payment date (or the Effective Date if it is the first accrual period) to and including the Common Event Determination Date and the resulting Fixed Amount in respect of the relevant Reference Entity is paid on the Cash Settlement Date. For tranche transactions, the "resulting Fixed Amount" is the accrual on the loss amount or recovery amount incurred on the relevant tranche (if any).

The "full coupon and rebate" methodology is generally applied when a standard CDS contract payment date (the "Affected Payment Date") occurs after the Event Determination Date, but before the auction settlement process is completed. This reflects the same economics as the "stub accrual" methodology (i.e. Fixed Rate accrues to and including the Common Event Determination Date), but the payment mechanics are different in order to facilitate settlement. Under the "full coupon and rebate" methodology, the Fixed Rate in respect of the relevant Reference Entity accrues from and including the previous payment date (or the Effective Date if it is the first accrual period) to but excluding the Affected Payment Date for purposes of the payment due on that date (unless the transaction matures on that date), i.e. "full coupon" is paid on that date. However, a rebate of the Fixed Rate accrual in respect of the relevant Reference Entity for the period from and including the calendar day after the Common Event Determination Date, to but excluding the Affected Payment Date, will be added to the Cash Settlement Amount to be paid to Buyer on the Cash Settlement Date. For tranche transactions, the "Fixed Rate accrual in respect of the relevant Reference Entity" is the accrual on the loss amount or recovery amount incurred on the relevant tranche (if any). For avoidance of doubt, in the "full coupon and rebate" the accrual for the "full coupon" is calculated on the pre-event total recovery and loss whereas the rebate is calculated using the event loss amount or recovery amount incurred. If the relevant transaction matures on the Affected Payment Date, the accrual is to and including the Affected Payment Date, then the Fixed Rate and the rebate will accrue to AND INCLUDING the Affected Payment Date. Finally, please note that if the Affected Payment Date falls on a non-business day, then the end of the accrual period for purposes of the Fixed Rate accrual and the rebate will adjust to the following business day, EXCEPT where the transaction matures on the Affected Payment Date, in which case it does NOT adjust, pursuant to Section 1.6 of the 2003 ISDA Credit Derivatives Definitions.
