We report the detection of exoplanet candidates in orbits around HD 60292 and HD 112640 from a radial velocity (RV) survey. The stars exhibit RV variations with periods of 4953 days and 6136 days, respectively. These detections are part of the Search for Exoplanets around Northern Circumpolar Stars (SENS) survey using the ber-fed Bohyunsan Observatory Echelle Spectrograph installed at the 1.8-m telescope of the Bohyunsan Optical Astronomy Observatory in Korea. The aim of the survey is to search for planetary or substellar companions. We argue that the periodic RV variations are not related to surface inhomogeneities; rather, Keplerian motions of planetary companions are the most likely interpretation. Assuming stellar masses of 1:7  0:2M⊙ (HD 60292) and 1:8  0:2M⊙ (HD 112640), we obtain minimum planetary companion masses of 6:5  1:0MJup and 5:0  1:0MJup, and periods of 495:4  3:0 days and 613:2  5:8 days, respectively.
