The year lease that you signed last month (June 2001) is a contract between you and the lessor. As such, there is really no way to break (breach) the lease/contract without suffering some repercussions unless allowed either by the lease or by the other contract party (landlord).
I would suggest that you either read the lease to see if there are any provisions allowing for early release (unlikely) or contact the landlord and see if he/she would consider your changing to a shorter term or month-to-month.
Additionally, most states do not allow the landlord to unilaterally keep security deposits as a result of breach. The security deposit is intended to protect against damages and unpaid rent, fees or penalties. As such, if your landlord re-leases the property shortly after your termination, he should not be able to keep the remaining portion of the deposit (depending on your state laws).
Here is an example: Rent is $750 per month and you breach the lease on September 1, 2001, and have $250 worth of damages. If you pay your rent for September, you're paid through Sept 31, allowing the owner several weeks to try to re-lease. Lets say he has a new tenant who starts paying rent on October 1. The landlord should only be able to deduct the $250 in damages from your deposit, and return $2750. However, if the new tenant rent doesn't start until November 1, then the landlord can deduct another $750 (rent for October) from your deposit and should return $2,000 to you.
Depending on your rent obligation and possible damages, it could be pretty hard for the landlord to keep the full amount of deposit.
