These two sentences are literally side by side and seem to be saying opposite things.
All deliverables and associated documents...developed by Contractor during the term of this Agreement shall belong to Agents or its clients for whom work is being performed by Contractor. Contractor retains all rights to source code or content, pre-existing code or content...or other methods it may employ in the course of creating deliverables for Agent.
With Deliverables defined as
Software provided in object and/or source format or documentation or any other materials required by Contractor by Agent...
In this scenario would it be interpreted in favor of the person who did not draft the terms? In general, does position in contract matter where a term occurs? For example if term A) is written on line 10 and term B) is written on line 11, is it reasonable to assume term B) takes precedence or modifies term A?
