Communication regarding urgency of transaction ,
 Here's a stab at it:

Many of you have received, or will receive in the next few days, requests for information that is necessary for regulatory filings related to the proposed merger with Dynegy.  Providing this information in the most accurate and expeditious manner possible is of the highest priority.   Thank you for your cooperation.

A slightly softer version would be:

Many of you have received, or will receive in the next few days, requests for information that is necessary for regulatory filings related to the proposed merger with Dynegy.  We recognize that you are facing many demands at this time, but please note that providing this information in the most accurate and expeditious manner possible is of the highest priority.  Thank you for your cooperation.
