(ii) If Vendor's contract with its applicable Subcontractor precludes AT&T from directly conducting an audit or inspection, Vendor shall use reasonable best efforts to enable AT&T to perform an audit of the Subcontractor with Vendor coordinating the audit process. Failing those efforts, Vendor shall, upon AT&T's request and at AT&T's expense, conduct the audit or inspection on behalf of AT&T, subject to terms agreed to by Vendor and AT&T for the Subcontractor audit, such as areas to be audited, applicable fees, and the timeframe for reporting audit results to AT&T. If AT&T's request for a Vendor audit or inspection arises from, in AT&T's good faith opinion, materially or consistently deficient Service provided by the Subcontractor under AT&T's account, and the audit in both Parties' opinions confirms such deficiencies, Vendor shall not charge AT&T a fee for the Vendor's audit of its Subcontractor. (iii) If Vendor's contract with its applicable Subcontractor does not allow Vendor access to the facilities and systems of Subcontractor required to conduct the audit described in Subsection (b) above, then Vendor shall provide a list of such Subcontractors and the services being provided by such Subcontractor to AT&T for its review. To the extent AT&T deems it reasonably necessary to require such access, then Vendor will renegotiate its contract with the applicable Subcontractor in order to obtain the audit rights described in Subsection (b) above.

Vendor may not obtain financing from any Restricted Entity or use any Cell Sites or Material owned, leased from, operated or financed by any Restricted Entity. 3.33 Severability. If any provision of this Agreement is determined to be invalid, illegal, or unenforceable, the Parties agree that the remaining provisions of this Agreement shall remain in full force if both the economic and legal substance of the transactions contemplated by this Agreement are not affected in any manner that is materially adverse to either Party by severing the provision determined to be invalid, illegal, or unenforceable. 3.34 Supplier Citizenship and Sustainability. Vendor shall conduct business with an abiding respect for corporate citizenship, sustainability, and human rights ("Citizenship and Sustainability"). Upon AT&T's request, which request may only be made once per calendar year, Vendor shall provide to AT&T reasonable information, reports, or survey responses to demonstrate Vendor's operation of its business in the context of Citizenship and Sustainability. 3.35 Survival of Obligations.
