Yes __X__ No ____ Part I - DISTRIBUTION INFORMATION Item 1. Distribution and Pool Performance Information On March 20, 2007 a revision was made to the December 26, 2006 distribution which was made to holders of Lehman Mortgage Trust 2006-6. The reason for this revision is Lehman informed Wells Fargo that there were some potential payments differences within their portfolio. Due to the nature of senior/sub deals, this difference in allocation of scheduled vs. unscheduled principal affected the cash flows for the individual certificates in the deal, overpaying the senior class and underpaying the subordinate class principal. The revised distribution report is attached as an Exhibit to this Form 10-D/A. Please see Item 9(b), Exhibit 99.1 for the related information. Part II - OTHER INFORMATION Item 9. Exhibits.
