Pure Evil

i need to get a hosting account (shared is fine) for a small mainstream project im about to start working on. Thanks to a friend, i've had an offer from a very reputable mainstream hosting company for a customized package including 150GB disk space and 1.5TB monthly transfer (1500GB) on a dual-core P4 box with (RAID) SCSI drives. My cost for all of this comes out to just under $150/yr.

now here is my question. i was reading the TOS and under Server Resources it reads:
Any Web site that uses a high amount of server resources (such as, but not limited to, CPU time, memory usage, and network resources) will be given the option to either pay additional fees (which will depend on the resources required), reduce the resources used to an acceptable level, or upgrade its service to a Dedicated Server plan. We will be the sole arbiter of what is considered to be a high server usage level. Any Web Hosting and Ecommerce account deemed to be adversely affecting server performance or network integrity will be shut down without prior notice.

is this pretty much stardard TOS for hosting companies or should i be concerned about this? i dont want my shit to just be taken offline without any notice.
