Relocation

Upon accepting my new position my first contract had a clause that states "if you voluntarily terminate your employment within one year of employment or within one year of your relocation to your location of your assignment with the company whichever is later, you will be required to reimburse the company. By your acceptance of this offer of employments and its relocation benefits, you acknowledge your understanding and acceptance of this policy.
I signed this policy in September and its been 4 months since I have relocated. In December I accepted a promotion and with that came a new contract. The new contract wording is the same except for the salary cost as changed and the entire relocation clause was removed. Based on the new contract I signed and it not having any verbiage about relocation if I break my new contract prior to 12 months and I still liable for the original contract I signed stating I must work 12 months or reimburse the company? If not what can I do to protect myself from the company coming after me? I am considering this because the company did not keep their promises they stated before I as hired.
Thanks for all of your advice.
