I'm not in that business; but I have had some experience with Covenants Not to Compete.
Before signing anything, remember you are already in the business . . . . in that territory.
By signing something like this, and subsequently parting ways, you could find yourself "out of business" at least in that territory . . . . and far worse off than you are now.
if our company will sign a no compete clause ?
I'd respond with "depends how it's worded". How restrictive; how small a Territory; and what is the definition of the business in which you would be prevented form engaging after severing your relationship? Let your Texas Attorney determine if it's too risky for you to sign.
