Emily was a Java programmer employed with SunMicrosystems in Palo Alto, California. Upon beginning employment, Emily signed a contract which included a noncompetition clause that prevented her from taking another Java programming position with any of five companies Sun listed as ‘‘direct competitors'' within three months of terminating her employment.

Later that year Emily resigned and two months later accepted a position with Hewlett-Packard (HP) in Houston, Texas. HP was listed in Emily's contract as a ‘‘direct competitor,'' but she argues that due to the significant geographic distance between both jobs, the contract is not enforceable. Explain whether the contract is enforceable.
