	client or the client's custodian or trustee bank has the
	right to receive dividends paid with respect to, and

	The ultimate power to direct the receipt of dividends paid with
	respect to, and the proceeds from the sale of, such securities,
	is vested in the individual and institutional clients which
	Price Associates serves as investment adviser.  Any and all
	discretionary authority which has been delegated to Price
	Associates may be revoked in whole or in part at any time

	Except as may be indicated if this is a joint filing with one
	of the registered investment companies sponsored by Price Associates
	which it also serves as investment adviser ("T. Rowe Price Funds"),
	not more than 5% of the class of such securities is owned by any
	one client subject to the investment advice of Price Associates.

	(2)	With respect to securities owned by any one of the
	T. Rowe Price Funds, only the custodian for each of such Funds,
	has the right to receive dividends paid with respect to, and proceeds
	from the sale of, such securities.  No other person is known to have
	such right, except that the shareholders of each such Fund participate
	proportionately in any dividends and distributions so paid.

	the securities and were not acquired and are not held in connection with

	T. Rowe Price Associates, Inc. hereby declares and affirms that the filing
