Is the long sentence okay?

What does "Phrase" mean?

Reference in any part of this Agreement, including this Description, the Revised Quotations, the Outline and/or the Time Line to any work to be done by either party in Phrase 4 is intended to be reflective only of the discussions of the parties to date and what they anticipate will be included in such a separate Phrase 4 agreement, if one is reached, although the parties do anticipate that the general framework of this Agreement will also apply to any such a separate Phrase 4 agreement, if and when one is finally negotiated.

Should it be 'Phase 4', Jobb?

If so, the paragraph would seem to be part of a agreement for some kind of work or service, with particular reference to 'Phase 4' of that work or service. (Perhaps an IT agreement.)

The paragraph seems to say that the agreement of which it is part applies only provisionally to the eventual separate agreement for 'Ph(r)ase 4'.

I would revise it as follows:

References that appear in any part of this Agreement in respect of any work to be done by either party in Phase 4, including references to this Description, the Revised Quotations, and the Outline and/or Time Line, are intended to reflect only the discussions of the parties to date and what the parties anticipate will be included in a separate Phase 4 agreement should such an agreement be reached. The parties do, however, anticipate that the general framework of this Agreement will also apply to any such separate Phase 4 agreement.

Jobb, I hope this helps until someone else comes along and maybe defines it better than I.
It is about foods? Autos? Or economy, etc.?

That is much clealer, taiwandave. Emotion: big smile

I guess "phase" means "an aspect, a part". Right?
