Introduction
Jonathan Winnick represents financial institutions that provide trustee and agency services in secured and unsecured financings, with concentrations in domestic and international project finance, corporate and municipal debt, mergers and acquisitions, and asset-backed securitizations.
My focus
My practice focuses on corporate trust matters. I represent major financial institutions and trust companies in a broad range of financing and restructuring transactions, serving as trustee, administrative agent, collateral agent, intercreditor agent, account bank, exchange agent, paying agent, escrow agent, and other agency and fiduciary capacities. I have extensive experience representing clients in project financings, corporate and municipal issuances of debt, private placements, escrow arrangements, mergers and acquisitions, and asset-backed securitizations. My project finance work includes cross-border transactions in Latin America. In addition, I advise my corporate trust clients on the development of product-related policies and procedures, and other risk management and regulatory compliance matters.
Representative experience
The representative experience listed below includes representations from a prior firm.
- Served as counsel to the administrative agent, offshore collateral agent and intercreditor agent in connection with VMOS S.A.’s $2 billion syndicated secured term loan facility to finance the development of the Vaca Muerta Sur Oil Pipeline project in Argentina. This transaction is the largest commercial loan for an infrastructure project in Argentine history and one of the top five oil and gas financings in Latin America.

The two financings combined were used to fund the acquisition by Castillo Hermanos, a Guatemala-based multinational diversified business group, of Harvest Hill, which is one of the nation's largest independent branded beverage companies.
- Served as counsel to the trustee, collateral agent, intercreditor agent and account bank in connection with Yinson Production’s USD 1.168 billion 144A/Reg S senior secured notes, which proceeds were used to refinance the floating production, storage and offloading vessel FPSO Maria Quitéria.
