“Material Breach” is not specifically defined in the Decile Base material provided, so the safest answer is:

- It generally means a **serious breach of the LPA**, not a minor admin error.
- Related “for cause” concepts commonly include:
- fraud
- willful misconduct
- gross negligence
- material breach of the LPA
- certain regulatory disqualifications

Once in **Limited Operations Mode**:
- it is triggered by LPs holding **more than 66 ⅔%** of commitments giving written notice
- the parties must **negotiate in good faith**
- the period lasts **90 days**
- it can be extended in additional **90 day** periods by further notice from the requisite majority

I can’t confidently confirm more specific GP powers from the provided material.
