	4.	take any other action of any type whatsoever in connection with the foregoing which, in the opinion of the Attorney-in-Fact, may be of benefit to, in the best interest of, or legally required by, Filer, it being understood that the documents executed by such Attorney-in-Fact on behalf of Filer pursuant to this Power of Attorney shall be in such form and shall contain such terms and conditions as such Attorney-in-Fact may approve in their discretion.

      The undersigned hereby grants to Attorney-in-Fact full power and authority to do and perform any and every act and thing whatsoever requisite, necessary, or proper to be done in the exercise of any of the rights and powers herein granted, as fully to all intents and purposes as the Filer might or could do if personally present, with full power of substitution or revocation, hereby ratifying and confirming all that such Attorney-in-Fact, shall lawfully do or cause to be done by virtue of this Power of Attorney and the rights and powers herein granted.

	Filer acknowledges that Attorney-in-Fact, in serving in such capacity at the request of Filer, is not assuming any of Filer's responsibilities to comply with Section 16 of the Exchange Act.
