Despite all the anxiety and uncertainty of the present, this is actually a very good time to prepare for a transition toward "life after CVS." I spent this weekend updating my resume, knowing I'll probably need to fine-tune a few details as this scenario progresses.
Other things to do in preparation, even if nothing materializes:
Have a few printed copies of your resume printed and ready to distribute on short-notice. Draft it so any changes that may be necessitated in the future can be easily made.
Prepare a cover letter template that you can easily edit and print (&/or save) should the need arise.
Find and set links to whatever unemployment benefits may be available. Pay particular notice if/how severance may affect your UI benefits. It's better to prepare ahead of time and not need the services than it is to scramble around later.
Make sure any job, or career, sites you use (or plan to use) are updated accordingly.
Basically, this advice is elementary "Job Search 101," but in these stressful times it's important to dust off the job-hunting skills and tools that many of us haven't needed to use for a long time.
