Not having the lease to read, I cannot give you a concrete answer. There is not an 'out' in California statutes for this with a commercial lease, there are some outs in residential leases.
If you have an illness or disability, I would approach your landlord with a compromise to terminate the lease. You may even want to consider trying to find someone to take over the lease or better yet, enter into a new lease with the landlord and thus releasing you completely.
If you did not personally guarantee the lease and you quit the lease early and he sues the company, you can always file for bankruptcy protection for the company and that halts the suit. Or if you wish to stay in the store and file for Chapter 11 protection, this would put him and your other creditors on a payment plan and thus give you the opportunity to ride out this wave of financial crisis and hopefully come out of Chapter 11 or if the economy does not turn around in time, you can convert to a Chapter 7. Either way, it gives you an out of the lease.
Now, if you signed personally, he can go after you personally. Look at your lease and see if there is the term 'guarantee' anywhere in the document and if you signed twice, onces as officer or director and once as an individual. If you did, then you are on the hook personally and you can file Chapter 13 for personal in addition to the Chapter 11 for the business.
If you tell him that if he does not help you and if he sues you that you will be forced to file bankruptcy that may make him more reasonable in his dealings with you.
I wish you the best.
