| • |     | secure all debt securities then outstanding with respect to which this covenant is made equally and ratably with 
 the Secured Debt; or                                                                                             |

| • |     | deliver to the trustee bonds, notes or other evidences of indebtedness secured by the Lien (as defined below)                                                                                                                                        
 which secures the Secured Debt in an aggregate principal amount equal to the aggregate principal amount of the debt securities then outstanding with respect to which this covenant is made and meeting certain other requirements in the indenture. |
