NC-2009 EAc1: Optimize Energy Performance
Is it acceptable to conduct the LEED 2009 Energy Modeling using Carrier HAP 4.3 version?
I read that HAP 4.3 is based on ASHRAE 90.1-2004 whereas in LEED 2009 the reference standard is 90.1-2007..so will there be any compliance issues if HAP 4.3 is used?

HAP is OK. The software does not create the baseline for you, so you'll have to create a baseline based on 90.1-2007.

Yep HAP is fine. It is just the "LEED Report" that HAP generates that is based on the LEED v2 (i.e. 90.1-2004) template reporting.
