H.R. 3743 amends the SBA disaster loan program to enable SBA to better respond to major disasters. Specifically, the bill authorizes such sums as necessary in Fiscal Years 2010 and 2011 to administer the program and increases the limit for disaster loans to $3 million (from $1.5 million) and increases the aggregate loan limit amount for a borrower to $3 million (from $2 million).

The bill further allows SBA to issue grants of up to $100,000 for small businesses affected by a disaster. Such sums as may be necessary are authorized for $100 million in such grants in each of Fiscal Years 2010 and 2011. H.R. 3743 authorizes $50 million in loan applicant assistance grants for each of Fiscal Years 2010 and 2011. These grants would go to women's business centers, small business development centers, Veteran Business Outreach Centers, and chambers of commerce in an area affected by a disaster.
