- Security Trust Agreement: Grants a security interest in substantially all of WEST's assets to the Security Trustee for the benefit of Note holders. These assets are ring-fenced and not available for Willis's general obligations.
- Servicing and Administrative Fees: Willis will serve as servicer and administrative agent, receiving fees based on net rents (8.0% senior rent-based fee, 3.5% subordinated rent-based fee, and 2.0% administrative fee) and a 3.0% fee on asset sale proceeds.
Risks and Contingencies: The Notes are not registered under the Securities Act of 1933 and were offered only to qualified institutional buyers under Rule 144A and outside the U.S. under Regulation S. The filing does not provide specific quantitative risk factors beyond standard covenant limitations.
