Syncing Google Calendar with a non-Google Calendar?

[AC Question]

I have a company issued Galaxy S5 running Android 5.0. It uses Airwatch to retrieve my corporate calendar from the corporate Exchange server and display it in the default calendar app (and other apps, like Google Calendar, aCalendar, etc.).

I would like a way to sync events from that calendar to my Google Calendar, so that I could see them on other devices, like my Nexus 7, or even using a browser to view the Google Calendar from a laptop. In a perfect world, this would be a two-way Sync so I could also enter events on the Nexus and have them replicate to the Airwatch/Exchange calendar, but I'll settle for one-way.

The solution must be an Android app as I don't have privileges to install PC based solutions (e.g., CompanionLink). Does not have to be a free app.

Thanks in advance...
