Is there any alternative to fisher exact test if cell count is less than 5?

When I ran proc freq I get warming where it indicated cell count are less than 5 and chi square may not be valid. Then I tried using fisher exact test, it was taking forever to run the proc freq with fisher test and not able to compute anything. If there is any alternative to fisher exact test if cell count are less than 5. Thank you.

/*You could MC option for Exact Fisher Test*/
proc freq data=sashelp.class;
table sex*age/fisher;
exact fisher/mc maxtime=60;
run;
