I am working on LEED CI 2009 Retail Shop. This shop is using existing wall, roof and floors and existing AC units in a shopping mall. In this shop there is window provision and surrounded by other shops also. There is no provision to provide window or making any opening for Fresh air required by ASHRAE 62.1-2007. Also in this mall there is Fresh air handling unit to provide fresh air in any shop so in this shop also there is no provison for mechanical ventilation. In both case mentioned above there is no chance to provide Fresh air required by ASHRAE 62.1-2007.
In this case, can this pre-requistes exempted? or is there any other way to comply with this prerequisite?

There is no exemption. You need to comply with ASHRAE 62.1-2007. If there's a fresh air system serving the mall, you'll want to work with the mall operators to see if adjustments can be made to supply enough ventilation air to the retail shop.
