(a)  The Borrower, and each other Obligor, agrees that at any time and from time to time, at the expense of the Borrower or such other Obligor, it will promptly execute and deliver all further instruments and documents, and take all further action that may be reasonably necessary, or that the Administrative Agent may reasonably require, to perfect and protect any Lien granted or purported to be granted hereby or by the other Credit Documents, or to enable the Security Agent to exercise and enforce its rights and remedies with respect to any Collateral.  Without limiting the generality of the foregoing, the Borrower will execute, if required, and file, or cause to be filed, such financing or continuation statements under the UCC (or any non-U.S. equivalent thereto), or amendments thereto, such amendments or supplements to the Collateral Vessel Mortgages (including any amendments required to maintain Liens granted by such Collateral Vessel Mortgages), and such other instruments or notices, as may be reasonably necessary, or that the Administrative Agent may reasonably require, to protect and preserve the Liens granted or purported to be granted hereby and by the other Credit Documents.
