Furthermore, the Lease Agreement contains an "adverse action" clause, which provides for payments by the PRPA to Aerostar in the event that any Puerto Rico governmental authority takes an action that is expected to be principally borne by Aerostar, private operators of comparable public airports or certain other classes of parties and that has a material and adverse effect on Aerostar's lease interest in LMM Airport. Payments to Aerostar as a result of an "adverse action" are guaranteed by the Government Development Bank of Puerto Rico.The text of the Lease and Use Agreements is available at the website of the Puerto Rico P3 Committee at http://www.app.gobierno.pr/?page_id=121.
