How to Query Contract Terms Template Clauses

Hi Everyone,

I need to extract all data on Contract Terms Templates page, and don´t know how to join the Terms Template Table with Clauses and Contracts too. as I've found a join from contracts to okc_terms_templates_all table stuck at identifying the join between clauses and templates.

Terms Template Table: 
- OKC_TERMS_TEMPLATES_ALL
   Key: TEMPLATE_ID

Clauses Table: 
- OKC_ARTICLES_ALL 
- OKC_ARTICLE_VERSIONS
   Key: ARTICLE_ID

Has anyone tell me how to link these tables?
