Regex to extract a field between 2 fixed words

Hi, I am having events, Number1=ABCDAS Number2=10 Number1=hsd gdsf Number2=1 Number1=ADG FHK Number2=11 Number1=HGSF Number2=4

I would like to extract the field value of Number1, Field value does not displaying any value after space in Splunk fields. Probably regex will help to extract ABCDAS, hsd gdsf, ADG FHK, HGSF Could anybody help to extract? Number1 & Number2 are constant fields...
