NOTICE TO MARKET PARTICIPANTS

Re: Revision to Q4/09 Report

The MSA published its Q4/09 Report on February 2, 2010. It has come to our attention that there is an error that affects a value in Section 1.1 of the report on Page 2. The last paragraph on Page 2 should read “Over the course of 2009, more than 500 MW were added to the generating capacity”. The revised version of the 2009 Quarterly Report is now posted to our web site.

We apologize for the error and any inconvenience that it may have caused.

Regards,

“Original Signed”
